Abstract

PURPOSE: To detect the incomplete connection of a terminal without any contact between a probe and terminal metal fittings by supporting a holder with a check pin and a contact probe using the casing of an inspection part so that the holder can travel back and forth and detecting the deformation of a lance with the contact of the check pin. CONSTITUTION: An inspection part is brought closer to a connector retention part by operating a lever. When terminal metal fittings 62 is positively inserted into a housing 61, a lance 63 is engaged to the metal fittings 62 and does not exist in a space 64 and a check pin 33 enters the space 64, a contact probe 34 contacts the metal fittings 62 for electrical conduction. On the other hand, when the meTal fittings 62 is not positively inserted, the lance 63 is not engaged to the metal fittings 62, remains to be displaced within the space 64 and the pin 33 contacts the lance 63. When an inspection part is brought closer to a retention part against the elastic energization of the pin 33, a holder H moves in a direction away from the retention part in reference to the retention part and the probe 34 cannot contact the metal fittings 62 for conduction, thus detecting the semi-inserted state of the metal fittings 62.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for inspecting a connector having a housing and terminal fittings attached to the housing. More specifically, the present invention relates to a connector inspection device that prevents a terminal fitting from coming off by engaging a lance provided in the housing with a terminal fitting inserted in a housing.

[0002]

2. Description of the Related Art Generally, a wire harness has a connector attached to its end. The connector is
It has a terminal fitting attached to an end of an electric wire which is a component of a wire harness, and a housing in which the terminal fitting is mounted. Then, the connector and the connector attached to the wire harness to be connected to each other or the connector attached to the side of the other electrical components are fitted to each other, so that the terminal fittings of both connectors come into contact with each other, thereby, Electrical connection between the wire harnesses and between the wire harnesses and other electrical components is achieved.

The work for attaching the connector is usually performed by previously crimping the terminal fitting to the end of the electric wire and inserting the crimped terminal fitting into the housing. Therefore,
In order to complete the assembly of the connector and to achieve a reliable electrical connection by fitting the connectors together, make sure that the terminal fittings are securely inserted into the housing and that the inserted terminal fittings are in the housing. It is required to prevent it from coming off easily.

First, in response to the above requirement, conventionally, a means is adopted in which an elastically deformable engaging claw called a lance is formed in the housing, and a bending space for allowing the elastic deformation of the lance is provided in the housing. There were cases. That is, when the terminal fitting is inserted into the housing, the lance is elastically deformed by being pushed by the terminal fitting, and is temporarily displaced in the bending space. Then, when the terminal fitting is inserted to the regular position, the displacement of the lance is elastically restored and the lance engages with the terminal fitting. As a result, the terminal fitting can be prevented from coming off.

On the other hand, in response to the above demand, conventionally, for example, an operator inserts the terminal metal fitting into the housing with great care, and empirically confirms the reliable insertion by hand. For example, after inserting the terminal fitting, pull it in the half-insertion direction. If the terminal fitting does not come off in this state, it can be determined that the terminal fitting is securely inserted to the predetermined position. However, in this work, there are cases in which the operator may erroneously recognize that the terminal metal fitting has been reliably inserted, although the terminal metal fitting is not surely inserted. For example, if you forget to pull the terminal metal fitting in the half-insertion direction to confirm that it is inserted securely, or if the operator does not insert the terminal metal fitting to the proper position, move it in the half-insertion direction. When pulling, the terminal metal may accidentally get caught in the housing, and it may be mistakenly recognized that the terminal metal has been securely inserted. In such a case, even if the connectors are fitted together, electrical continuity between the terminal fittings cannot be obtained, and as a result, the electrical connection between the wire harnesses that should be connected to each other is not achieved, and the electrical components are not electrically connected. Various adverse effects such as malfunction of products and the like occur.

In order to prevent such an adverse effect, conventionally, in the process of manufacturing a wire harness, a connector inspection is performed to check whether or not the terminal fitting is completely attached to the housing. This inspection is performed using a dedicated inspection device, and this device is called a connector inspection device (see Japanese Patent Laid-Open No. 7-73949). FIG. 10 is a conceptual diagram schematically showing the concept of a conventional connector inspection and connector inspection device. Referring to FIG. 1, the connector inspection apparatus includes a holding unit U1 that holds a connector to be inspected in a positioning state during inspection, and an inspection unit U2 that is disposed so as to face the holding unit U1 and that can contact and separate from the holding unit U1. And have.
The inspection unit U2 includes a continuity inspection probe 2 that comes into contact with the terminal fitting 1 of the connector to be inspected, and a lance check pin 4 to detect whether or not the lance 3 formed in the housing of the connector to be inspected is deformed. ing. The lance check pin 4 constitutes a normally closed switch 4a, and when the lance check pin 4 is pushed rightward in the drawing, the switch 4a is opened. The continuity inspection probe 2 and the switch 4a are
They are arranged in series and connected to the continuity inspection circuit 5.

FIG. 11 is a view showing the positional relationship among the terminal fitting 1, the lance 3 and the lance check pin 4. To describe with reference to FIGS. 10 and 11, in order to perform the inspection, the inspection unit U2 and the holding unit U1 are brought close to each other, and the connector to be inspected is fitted to the inspection unit U2. At this time, if the terminal fitting 1 is properly attached, the terminal fitting 1
Since the lance 3 is engaged with the lance 3, the lance check pin 4 enters the bending space 3a (see FIG. 11A) and the continuity inspection probe 2 contacts the terminal fitting 1. As a result, electrical continuity between the terminal fitting 1 and the continuity inspection probe 2 is obtained, and as a result, it is detected that the terminal fitting 1 is properly mounted.

On the other hand, when the terminal fitting 1 is not properly mounted, the lance 3 remains displaced in the bending space 3a (see FIG. 11 (b)). Therefore, the lance check pin 4 trying to enter the flexible space 3a is
Abut. As a result, the lance check pin 4 is relatively pushed to the right side in the drawing to open the switch 4. In other words, even if the continuity inspection probe 2 is in contact with the terminal fitting 1, it is impossible to obtain electrical continuity between the two because the switch 4 is opened. As a result, the terminal fitting 1
Is detected to be not properly attached.

[0009]

The inspection is performed as described above. In the conventional connector inspection apparatus, the lance check pin 4 has a switch function, and the switch 4a is opened by contacting the lance 3. It was necessary to make the structure. Therefore, the structure of the lance check pin 4 is complicated, and as a result, the connector inspection device is expensive as a whole.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive connector inspection device having a simple structure and capable of inspecting the complete mounting of the terminal fitting and the reliable retaining.

[0011]

In order to achieve the object of the present invention, a connector inspection device according to claim 1 has a plurality of terminal fittings and a housing into which each terminal fitting is inserted.
Inside the housing, there are provided elastic engaging claws formed corresponding to the respective terminal fittings and a bending space formed corresponding to each elastic engaging claw for allowing elastic deformation of the elastic engaging claws. Each of the elastic engagement claws is elastically displaced into the bending space once the terminal fitting inserted into the housing comes into contact therewith, and the elastic displacement is restored when the terminal fitting is inserted in a predetermined position. Is engaged with the terminal fittings,
A connector inspection device which is applied to a connector designed to prevent the terminal metal fitting from coming off, and inspects the connector according to the presence or absence of electrical continuity with the terminal metal fitting. It has a connector receiving portion to be held, an inspection portion arranged to face the connector receiving portion, and a displacement means for moving the opposing distance between the both by moving at least one of the connector receiving portion and the inspection portion. The inspection section is provided corresponding to each terminal fitting of the connector held in the connector receiving section, and the detector that can come into contact with each terminal fitting when the inspection section and the connector receiving section are close to each other, and the connector receiving section. Are provided corresponding to the positions of the respective bending spaces formed in the housing of the connector held by the connector, and the inspection unit and the connector receiving unit are close to each other. Check member that can be moved into the bending space in a stationary state, a holder that holds each detector and check member in common, a holder that is slidably supported along the slide direction of the inspection unit, and a holder that always receives a connector. And a slide mechanism for elastically urging the section.

Further, in order to achieve the object of the present invention, the connector inspection apparatus according to a second aspect is the connector inspection apparatus according to the first aspect, wherein the inspection section has a casing for supporting the holder, and the slide is provided. The mechanism has a slide groove formed in the casing into which the holder is fitted, and an elastic member interposed between the casing and the holder.

[0013]

According to the connector inspection apparatus of the first aspect, the connector to be inspected is held by the connector receiving portion, and the inspection portion and the connector receiving portion are brought relatively close to each other. At this time, if the terminal fitting is securely inserted to the predetermined position of the housing, the elastic engaging claws engage with the terminal fitting.
Does not exist in the flexure space. Therefore, the check member enters the bending space and the detector contacts the terminal fitting. As a result, electrical continuity between the detector and the terminal fitting can be obtained.

On the other hand, if the terminal fitting is not securely inserted, the elastic engaging claw cannot be engaged with the terminal fitting and remains displaced in the bending space, so that the check member will enter the bending space. Then, the check member and the elastic engagement claw come into contact with each other. The check member is held by a holder, and the holder is always elastically biased toward the connector receiving portion side via a slide mechanism. Therefore, even if the check member and the elastic engagement claw are in contact with each other, the check member is relatively pressed by the elastic engagement claw when the inspection part is brought close to the connector receiving part against the elastic force. . As a result, the holder slides in the direction away from the connector receiving portion with respect to the inspection portion. As a result, the detector cannot come into contact with the terminal fitting, and the electrical continuity between the detector and the terminal fitting is not achieved.

According to the connector inspection device of the second aspect, the same operation as the invention according to the first aspect is achieved. In particular,
In the invention according to the present claim, the holder is biased toward the connector receiving portion side by the elastic member, and the holder comes into contact with the elastic engaging claw so that the holder is attached to the casing of the inspection portion. Slide along the slide groove. Thus, the structure of the slide mechanism is extremely simple.

[0016]

The base member 10 is formed, for example, in a U-shaped cross section and can be fixed to a substrate called an inspection drawing board. As a result, the connector inspection device A
It is designed to be mounted on the inspection drawing board. That is, the connector attached to the end can be inspected while the assembled wire harness is placed on the inspection drawing board.

The connector receiving portion 20 is for holding the connector to be inspected by pushing it in from above (in the direction of the white arrow). Here, a connector generally means a connector including a terminal fitting and a housing.
The terminal metal fitting is a metal fitting crimped to each electric wire end included in the electric wire bundle that constitutes the wire harness, and is inserted into the housing.

The connector receiving portion 20 is made of synthetic resin, for example. A notch 22 is formed in the connector receiving portion 20 from its upper surface 21 downwardly, so that the connector receiving portion 20 is formed in a substantially U-shaped block shape. The connector has the cutout 2
It is designed to be housed and held so that it does not move within 2. That is, the shape of the inner peripheral surface of the cutout portion 22 is formed so as to match the shape of the side peripheral surface of the housing of the connector to be inspected, and the housing fits the cutout portion 22 in a state of protruding toward the inspection portion 30 side. It is designed to be fitted.

FIG. 2 is a plan view of the inspection unit 30. FIG.
With reference to FIG. 2 and FIG. 2, the inspection unit 30 is for fitting with the connector held by the connector receiving unit 20 to establish electrical continuity with the connector. Inspection section 3
Reference numeral 0 denotes a substantially rectangular parallelepiped block shape, a casing 31 having a concave portion 31a opened on the front surface 30a and the upper surface 30b, and a holder H fitted in the concave portion 31a.
And a check pin 33 provided on the holder H and a contact probe 34 as a detector. Reference numeral 31c indicates a lid member attached to the casing 31. By attaching the lid member 31c, a space into which the connector to be inspected is fitted is defined.

The recessed portion 31a of the casing 31 will be described in detail. The recessed portion 31a extends in order from the front surface 30a side of the casing 31 to the rear surface side thereof and the general fitting portion 3 in that order.
6. A slide groove portion 37 and a penetrating portion 38 are formed. The inner surface shape of the general fitting portion 36 is such that when the inspection portion 30 is brought close to the connector receiving portion 20,
The connector retained in the is finished in a shape that allows it to fit snugly.

The slide groove portion 37 is continuous with the general fitting portion 36 and extends by a predetermined length toward the rear surface side of the casing 31. The slide groove portion 37 is for sliding the holder H in the front-back direction, that is, in the state of being guided in the same direction as the slide direction of the inspection unit 30.
In other words, the inner surface shape of the slide groove portion 37 is the same as the general fitting portion 3
The lateral width of 6 is expanded to form a rectangular shape, and the slide piece 51b of the holder H is formed along the slide groove portion 37.
Is designed to slide. Also, the penetration portion 38
Is formed so as to be continuous with the slide groove portion 37 and penetrate the rear surface of the casing 31. The inner surface shape of the penetrating portion 38 is formed in a rectangular shape, and the lateral width thereof is narrower than the lateral width of the general fitting portion 36.

The holder H has a block shape and is disposed in the recess 31a. The holder H has a fixed piece 51.
It has a and the slide piece 51b. Fixed piece 5
1a is fitted in the penetrating portion 38 and is slidable on the side surface 38a (see FIG. 2) of the penetrating portion 38. In addition, the slide piece 51b includes the slide groove portion 3 described above.
7, and the side surface 3 of the slide groove 37.
7a (see FIG. 2) is slidable.

A coil spring SP is arranged inside the slide groove 37 (see FIG. 2). As a result, the holder H is constantly elastically biased toward the front surface 30a of the casing 31. Therefore, from the state of FIG.
When the holder 32 is pushed in the direction of the white arrow against the elastic force of P, the holder 32 slides with respect to the casing 31.

A check pin 33 and a contact probe 34 are attached to the holder H. The check pin 33 and the contact probe 34 are arranged so as to project toward the connector receiving portion 20.
When the holder H slides, the check pin 33 and the contact probe 34 also slide integrally with the holder 32 as shown in FIG.

In this embodiment, the inspection unit 30 is for a so-called 4-pole connector, and the check pin 33 is used.
And four contact probes 34 are provided respectively. The check pin 33 can be composed of, for example, a metal rod. The check pin 33 is embedded in the holder H, and the tip portion thereof is largely projected forward from the holder H. Contact probe 3
The holder 4 is also supported by the holder H, and its front end portion slightly projects from the holder H forward, and its rear end portion projects slightly rearward from the holder H. A lead wire RE for taking out a signal is connected to the rear end of the contact probe 34, and is connected to an inspection device (not shown).

The lever device 40 has a lever 41 and an interlocking mechanism. The lever 41 is rotatably attached to the stay 12 erected at the end of the base member 10 via a pin P. The interlocking mechanism includes an interlocking shaft 41a provided on the lever 41 and a connecting arm 41b connecting the interlocking shaft 41a and the casing 31 of the inspection unit 30.

Therefore, when the lever 41 is rotatably raised in the direction of the white arrow, the interlocking shaft 41a moves in conjunction with the lever 41, and the connecting arm 41b causes the interlocking shaft 4a to move.
The inspection unit 30 is moved in association with the movement of 1a. Since the inspection unit 30 is allowed to be displaced only in the direction along the rail 11, the inspection unit 30 is operated by operating the lever 41.
Are moved closer to the connector receiving portion 20 side. In addition, if the lever 41 is rotated in the direction opposite to the direction of the white arrow,
The inspection unit 30 returns to the original position. Although the inspection unit 30 is slid by the lever device 40 in the present embodiment, the inspection unit 30 may be fixed and the connector receiving unit 20 may be slid.

Next, with reference to FIGS. 4 to 6, how to use the connector inspection device A will be described together with operational effects. 4 to 6 are diagrams schematically showing the positional relationship between the connector 60 to be inspected and the holder H when the inspection unit 30 is viewed from the side. In this embodiment, a female terminal fitting is attached to the connector 60 to be inspected.

First, referring to FIG. 1, the connector 60 to be inspected is mounted on the connector holding portion 20, and the connector 60 is held in a positioned state. At this time, the connector 60,
The positional relationship with the holder H is as shown in FIG. The connector 60 will be described in detail with reference to FIG. 4. The connector 60 includes a housing 61 and a female terminal fitting (hereinafter referred to as “terminal fitting”) inserted therein.
62 and. A lance 63 is formed in the housing 61 integrally with the housing 61. The lance 63 is elastically deformable. In addition, the housing 61 is formed with a bending space 64 that allows the deformation of the lance 63 when elastically deformed.

The connector 60 is assembled by inserting the terminal fitting 62 into the housing 61. The relative positional relationship between the terminal fittings 62 when they are inserted into the housing 61 is as follows. That is, when the terminal fitting 62 is inserted into the housing 61, the terminal fitting 62 contacts the lance 63. This is the terminal fitting 62
When is pushed in, the lance 63 is elastically deformed once so as to be pushed away by the terminal fitting 62. This variant is
The lance 63 is allowed to move into the bending space 64. When the terminal fitting 62 is correctly inserted to the proper position, the lance 63 engages with the terminal fitting 62. That is, the elastic deformation of the lance 63 is restored,
The lance 63 engages with the terminal fitting 62 by retracting from the bending space 64 and returning to the original state. On the other hand, if the terminal fittings 62 are not installed correctly, the lance 6
3 cannot be engaged with the terminal fitting 62 while being elastically deformed. Therefore, the lance 63 has the bending space 64.
It remains displaced inward.

Referring again to FIG. 1, then lever 41
Is operated to bring the inspection unit 30 close to the connector holding unit 20. With reference to FIG. 5, at this time, if the terminal fitting 62 is securely inserted to the predetermined position of the housing 61, the lance 63 is engaged with the terminal fitting 62, and therefore does not exist in the bending space 64. . Therefore, the check pin 33 can enter the bending space 64 without any trouble, and the contact probe 34 comes into contact with the terminal fitting 62. As a result, the contact probe 34 and the terminal fitting 6
2 is electrically connected to each other, and as a result, the terminal fitting 62
Can detect that the correct position has been inserted.

Referring to FIG. 6, on the other hand, if the terminal fitting 62 is not securely inserted, the lance 63 will be
When the check pin 33 tries to enter the flexible space 64, the check pin 33 and the lance 63 come into contact with each other, because the check pin 33 cannot be engaged with 2 and is still displaced in the flexible space 64. The check pin 33 is held by the holder H, and the holder H is constantly elastically biased toward the connector receiving portion 20 (in the direction of the white arrow in the drawing) by the coil spring SP. Therefore, even if the check pin 33 and the lance 63 are in contact with each other, the check pin 33 is relatively pushed by the lance 63 when the inspection part 30 is brought close to the connector receiving part 20 against the elastic force. The holder H is slid with respect to the inspection unit 30 in the direction away from the connector receiving unit 20. As a result, the contact probe 34 cannot contact the terminal fitting 62, and the contact probe 34 and the terminal fitting 6 do not contact each other.
No electrical continuity with 2 is achieved. That is, the terminal fitting 6
2 can detect that it has not been correctly inserted to the proper position (referred to as a "semi-inserted state").

As described above, in this embodiment, the terminal fitting 62
In order to detect the half-inserted state, the presence or absence of deformation of the lance 63 is detected. That is, by bringing the check pin 33 into contact with the deformed lance 63, the contact probe 34 is moved away from the terminal fitting 62 and the contact between the two is interrupted, whereby the terminal fitting 62 is half-inserted due to the deformation of the lance 63. Detect the condition. Therefore, the terminal fitting 62
Since a switch mechanism for detecting the half-inserted state is not provided, the connector inspection device A can be provided at low cost. Particularly, in the present embodiment, as a mechanism for sliding the holder H, the holder H is fitted into the slide groove portion 37 formed in the casing 31, and the holder H is elastically biased forward by the coil spring SP, which is extremely simple. Since the structure is simple, the connector inspection device A can be provided at a lower cost.

The present invention is not limited to the above embodiment, and the following modified examples can be considered. (1) In the above embodiment, the terminal fitting 62 of the connector 60 to be inspected has been described as a female one, but a connector equipped with a male terminal fitting can also be subjected to the same connector inspection.

FIG. 7 is a perspective view of a connector inspection apparatus A used when inspecting a connector to which a male terminal fitting is attached. The connector inspection apparatus A according to this modification is different from the above-described embodiment in the shape of the holder H of the inspection unit 30. That is, in the connector inspection device A according to this modification, the holder H of the inspection unit 30 has the base portion 51 and the guide portion 52 provided on the front surface of the base portion 51. Base 5
Reference numeral 1 has the same shape as the holder H in the above-described embodiment, and has a fixed piece 51a and a slide piece 51b. The description of the fixed piece 51a and the slide piece 51b is omitted. In addition, in FIG. 7, the lid member 31c of the inspection unit 30 is shown in a removed state.

The guide portion 52 has a substantially cubic shape,
A terminal fitting insertion hole 52a and a check pin insertion hole (not shown) opened on the front surface are formed. The terminal metal fitting insertion hole 52a is adapted to be inserted with the terminal metal fitting of the connector to be inspected when the inspection part 30 is brought close to the connector receiving part 20. The tip of a contact probe (not shown) provided on the base 51 is arranged. The check pin insertion hole guides the check pin 33, and the check pin 33 attached to the base portion 51 is inserted therein. The tip of the check pin 33 projects as shown in the figure. Since other configurations are similar to those of the above-described embodiment, the same reference numerals are given to the same configurations and their description is omitted.

According to this modification, if the terminal fitting of the connector to be inspected is correctly inserted to the proper position of the housing, the check pin 33 enters the bending space of the connector and the terminal fitting is Terminal fitting insertion hole 52a
It is inserted inside, and the terminal fitting and the contact probe come into contact with each other, so that conduction between them is obtained. As a result, the normal insertion of the terminal fitting can be detected. On the other hand, if the terminal fitting is not inserted correctly, the check pin 33 cannot enter into the bending space as in the above embodiment, and as a result, conduction is obtained between the terminal fitting and the contact probe. It is possible to detect that the terminal fitting is not correctly inserted to the proper position.

(2) FIG. 8 shows another modified example of the casing 31 and the holder H, and is a perspective view in which a part of these is broken. FIG. 9 is a partial cross-sectional side view showing a state where the connector 60 is inspected by the inspection unit 30 having the casing 31 and the holder H. With reference to FIGS. 8 and 9, a feature of this modified example is that the holder H is supported by the casing 31 so as to be slidable in the front-rear direction, and the front surface 3 of the casing 31.
0a through the opening 39 provided in the casing 31
The coil spring SP is interposed between the holder H and the casing 31, and the holder H is urged so as to always protrude forward from the opening 39 of the casing 31. Point, the tip of the holder H has a so-called slotted groove 5
Two of them 6 are formed, the contact probe 34 is arranged in the groove 56, and a projecting piece 55 is formed on the tip end surface of the holder H outside the groove 56. The piece 55 is that it constitutes a check pin.

More specifically, the casing 31 has a container-shaped member 31b whose rear surface is open and a lid member 31c attached to the rear surface. Container-like member 31
A rectangular opening 39 is provided on the front surface 30a (the front surface of the casing) 30b. On the other hand, the holder H has a substantially prismatic shape whose outer peripheral surface conforms to the inner peripheral surface of the opening 39, and is fitted exactly into the opening 39.
At the rear end of the holder H, the holder H has a casing 31.
A flange F is formed to prevent the flange F from coming off. The coil spring SP is arranged between the inner surface of the lid member 31c and the end surface of the flange F. As a result, the holder H is urged in the direction of protruding from the casing 31, and the flange F is pushed by the container-shaped member 31c.
The holder H is prevented from popping out by coming into contact with the inner surface of the holder (state of FIG. 8).

According to this modification, if the terminal fittings 62 are properly mounted, as in the above embodiment, the protruding piece 5
5 enters the bending space 64 of the housing 61 of the connector 60 to be inspected, and the terminal fitting 62 enters the groove 56 and comes into contact with the contact probe 34, thereby detecting the correct mounting of the terminal fitting 62. can do. Further, as shown in FIG. 9, when the terminal fitting 62 is in the half-inserted state, the protruding piece 55 contacts the lance 63, and the holder H retracts with respect to the casing 31. As a result, the terminal fitting 62 cannot come into contact with the contact probe 34, which makes it possible to detect that the terminal fitting 62 is not correctly mounted.

Besides, various design changes can be made within the scope of the present invention.

[0044]

According to the first aspect of the invention, when the terminal fitting is in the half-inserted state, the check member comes into contact with the elastic engaging claw displaced in the bending space, and the holder is connected to the connector via the slide mechanism. Slide in the direction away from the receiving part.
As a result, electrical continuity between the detector and the terminal fitting is not achieved, and as a result, it is possible to detect incomplete insertion of the terminal fitting and incomplete removal prevention. In other words, when the terminal fitting is in the half-inserted state, the detector and the terminal fitting cannot contact each other, so that electrical continuity cannot be obtained between them, and a sensor for detecting the half-inserted status of the terminal fitting is provided. No need for switches or switches. Therefore, the connector inspection device can be provided at low cost.

According to the invention of claim 2, the same effect as that of the invention of claim 1 can be obtained. In addition, since the holder slides along the slide groove of the casing provided in the inspection unit and is biased by the elastic member interposed between the holder and the casing, the structure of the slide mechanism is simple. Therefore, the cost of the connector inspection device can be further reduced.
