Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides one crimp terminal of the crimp terminal strip for the end of the electric wire.
The present invention relates to a strip-shaped body of an electric wire end portion identification display device suitable for being attached to the electric wire end portion before or after crimping as an independent operation, or in cooperation with an operation of continuously crimping while separating each piece.

<Prior Art> A wide range of wiring methods are available in which a large number of electric wires fitted with conductive terminals are collectively attached to a male / female pair of connectors, and simultaneous electrical connection / disconnection of the large number of electric wires is possible. It is being appreciated. In addition, it is often necessary to connect many wires in a complicated state. In these cases, it has been widely practiced to attach a marker to each wire end to eliminate mistakes in wire connection work, but since it was mostly done manually in the past, identification to a huge number of wire ends was done. Fixture mounting was extremely complicated and inefficient.

<Problems to be Solved by the Invention> In view of the above-mentioned circumstances, the present applicant has filed a patent application for “a wire end identifier mounting method and device” on December 29, 1991. A wire identification indicator suitable for use in a device, in particular, a strip-shaped body formed by connecting and forming a large number of wire identification indicators suitable for inserting the holder (11) for holding and expanding the indicator in the device into the aligned tip end portion. For the purpose of providing.

<Means for Solving the Problem> In order to achieve this object, the strip of the electric wire identification and display device according to the present invention is formed from a flexible synthetic resin flat plate-shaped main body portion in the vicinity of both end edges of the rear surface to form a partial arc shape. A pair of projecting pieces having inner surfaces of the projecting pieces are connected in parallel to each other, and the tip edges of the projecting pieces are parallel to each other and substantially parallel to the plate-like body portion. A large number of display devices, each having a reversibly expandable / reducible clearance formed between them, are connected in parallel to each other in a strip shape via a connecting portion, and the display devices at the ends extend in an ear shape via the connecting portion. And a width of the ear-shaped extension is the same as the length of each indicator, and a vertical fold of substantially the same length as the protruding piece from both end edges to the same side as the protruding piece. It is characterized in that the bent portion is continuously provided.

The electric wire identification display tool strip of the present invention is designed to facilitate smooth and easy supply to the device of the above-mentioned prior invention of the present applicant, and to reliably use the display tool at the end of the strip without waste. It is desirable that the tongue pieces are provided so as to project from the outer edges of both sides of the connecting portion in order to accurately and easily carry the apparatus or the display device separating apparatus in the preceding step thereof or the printing apparatus.

The above-mentioned ear-shaped extension part is additionally extended from the end display part through the connecting part so that the display parts connected in a required number of strips can be used up to the last one under the same conditions. Therefore, the width of the ear-shaped extension portion is the same as the length of each display tool, that is, the substantial width of the strip-shaped member, and the width of the vertical bent portion continuously provided from both end edges to the same side as the protruding piece. The height is almost the same as that of the protrusion.

The pair of the projecting pieces having a partially arcuate inner surface extends over the entire length of the plate-like main body portion on which the identification mark is to be printed, affixed or stamped on the front side, or a length of 1/2 or less thereof. Alternatively, it has a length of 1/2 or more and is projected from the back side of the main body portion.

Further, in the case where the opposed tip edges of the both protruding pieces of each unit display tool form a tapered wide notch region that gradually recedes in a direction away from each other toward the one end side of the clearance, When loading into the prior application device, it is convenient and easy to insert the display tool holding and expanding holder (11) of the device into the aligned tip end portion, which is convenient.

<Operation> The electric wire identification display device of the present invention has the band-shaped body adapted to be conveyed to the prior application device as described above. Therefore,
First, the main part of the prior application device will be briefly described with reference to FIG. 15. As shown in FIG. 15F, the wire end portion D to which the crimp terminal T is attached is as shown in FIG. It is held on the wire mounting table (S) at the bottom of the device. A pair of swing arms (Y) and (Y) are pivotally attached to the lower part of a reciprocating body (R) that is sandwiched between guide rollers (G) and moves up and down toward the mounting table, and the arms are outwardly directed. They are always biased toward each other and in an open position. However, when the guide rollers (G) are in a regulated state ((a) in the figure) and the pair of display tool holding / expanding holders (11) fixedly attached to the lower surface of the arm have the aligned tip portions. In the state where the tool (H) is thrust into the clearance (4) (described later) and is restrained ((b) to (c) in the figure), the open posture cannot be taken. That is, as the reciprocating body (R) descends, the electric wire end (D) enters the space between the holders (11) while interrupting, and at that time, the tip end of the holder (11) clears the clearance (4) of the display tool (H). ) Is extended, the electric wire end portion (D) reaches the bottom of the electric wire accommodating recess of the display tool (H), and then the reciprocating body (R) descends slightly against the elasticity of the spring (B). In the state of (d), the protruding piece (2) added to the arm (11)
After being released from the restraint (described later), the arm retracts to the side. At the same time, the protrusion itself of the display tool (H) is also restored to the original posture and the clearance is also restored to the original width. Therefore, in the display tool, the wire end portion is surrounded by almost the entire circumference thereof. Will be installed. Thus, the electric wire mounting base (S) is left with the end of the electric wire as shown in the same figure (g) with the display tool (H) attached, and then the reciprocating body (R) is attached as shown in the same figure (e). When going up, the end of the electric wire is ready to be taken out of the apparatus, while the guide roller (G) again restricts the swinging arm (Y) to return to the closed posture, and as shown in FIG. Return to the state.

Since the electric wire identification indicator which constitutes the strip of the present invention is used in the method and apparatus of the prior application, as described above, the flat plate-like main body portion made of a flexible synthetic resin is near the both end edges of the back surface. A pair of projecting pieces that are continuous from each other and have partial arc-shaped inner surfaces and are parallel to each other are formed between the tips of the plate-shaped main body portions in parallel with each other, and the reversibly widen clearance allows external force to be applied. The width in the normal state without addition is made as narrow as possible, and the thickness of the aligned tip portions of the pair of holders (11) for expanding and holding the display tool fixed to the lower surface of the device swing arm is also as follows. Corresponding to that, the structure is related to the fact that it is made thin enough.

That is, the width of the holder (11) is narrow in the direction parallel to the aligned front end of the holder (11), that is, in the direction of the axis of the recess for accommodating the end of the wire provided in the display tool (the direction perpendicular to the paper surface in FIG. 15 (a)). When the clearance is inserted into the thin-walled holder-aligned tip portion, both tip edges on one end side of the clearance are gradually retracted in the direction away from each other toward the one end. The wide notch acts as a guide for the insertion and facilitates the insertion operation.

Moreover, since the tapered wide notch region stops near the edge of the clearance and is shorter than the entire length of the clearance, there is no fear of impairing the force of attaching the display tool to the end of the wire.

The above is a description of the display device as a single body which constitutes the band-shaped body in advance. The action of the band-shaped body itself peculiar to the present invention is as follows.

That is, in the strip, two rows of rectangular tongues projecting at regular intervals along both outer edges of the strip are accurately engaged and disengaged from a pair of sprocket wheel-like feed mechanisms (not shown),
Therefore, it is supplied to the prior application device in the direction of the arrow (Z) in FIG. 16 (a) without skewing.
Then, in the process of feeding to the above-mentioned device, for example, an alphanumeric type identification symbol (9) is printed on the surface of the plate-shaped main body portion (1), and then cut lines (C) and (C) in FIG. They are cut out one by one, and then inserted into the device in the direction of arrow (X) in FIG.

In the band-shaped body of the present invention, the ear-shaped extension portion as described above,
Since it extends from the end of the display devices connected in strips, the strip is supplied to the prior application device even when the display device at the end is cut off, or a cutting mechanism for cutting into a single unit. Alternatively, it is securely held without any fear of causing vertical and horizontal glare when being processed inside the printing mechanism or the like, and these processes can be uniformly performed up to the last display tool.

If a rectangular cutout is provided in the connecting portion on which the tongue piece is projected, it is sufficient to cut along the short cut line (C) leading to the cutout while avoiding the tongue piece, and therefore the cutting is easy.

In addition, since the tongue piece is automatically cut off at the same time when the display tool is disconnected, the presence of the tongue piece adversely affects the use and action of the wire identification tool as a single piece. There is no fear of it.

<Embodiment> An illustrated embodiment will be described below with reference to Figs.
In this wire identification indicator (H) made by injection molding using polypropylene in the first embodiment of the figure, the flat plate-shaped main body portion (1) has a partial arc-shaped inner surface from the vicinity of both end edges of the back surface. A pair of projecting pieces (2) having parallel lines are provided in parallel with each other, and the tip edges (3) and (3) of the projecting pieces (2) are parallel to each other and with respect to the plate-shaped main body portion (1). However, a clearance (4) capable of widening is formed between the two leading edges (3) and (3), and both leading edges (3) on one end side of the clearance (4) are formed. , (3) gradually recedes in a direction away from each other as they go toward the one end, forming a tapered wide notch region (5).

As shown in FIG. 2 (a), the electric wire identification display tool (H) is
A large number of strips are formed in parallel with each other through the connecting portions (6), (6) arranged near both ends to form a strip, which is directed to the above-mentioned prior application device in the direction of arrow (Z) in FIG. 16 (a). After being supplied, an alphanumeric type identification symbol (9) is printed on the surface of the plate-like body portion (1) in the process, and then the second
Cut one by one along the cutting line (C) (C) in the figure,
Then, it is inserted into the device in the direction of the arrow (X) in FIG. Specifically, as described above, the aligned tip end portion of the holder (11) as shown in FIG. 15 (f) is tightly fitted into the clearance (4). At this time, the tapered wide notch region (5) on the one end side of the clearance acts as a guide portion, and the fitting can be performed easily and reliably. The contents of the subsequent operation are as already described in the <action> column, and the display tool is finally applied to the end of the electric wire in the direction of the arrow (F) in FIG.

A further important point in the present invention is that the end of the display device is connected so that a series of display devices (H) in the form of strips can be supplied to the end in the arrow (Z) direction of FIG. 16 (a) under the same conditions. The point is that the ear-like extension (10) is extended through (6). As shown in FIGS. 2 (a) and 2 (b), the width of the ear-like extension (10) is the same as the length of each display tool (H), and is the same as the protruding piece (2) from the vicinity of both end edges thereof. A vertical bent portion (10a) having the same height as the projecting piece is continuously provided on the side. Therefore, the posture is constant even when the last display tool (H ') forming a strip is cut off, and the last cut off display tool (H') is fed to the inside of the supply mechanism in the prior application device. The supply can be ensured.

A tongue piece (7) is projected from the outer edges of the pair of facing connecting portions (6) and (6), which is accurate when supplying the belt-shaped body to the device. The rectangular notch (8) between the connecting portions (6) and (6) not only saves the material but also the cut line (C) shown in FIG. 2 (a). ) Has the effect of facilitating cutting.

Further, the protrusion (2) has a shape in which it gradually transitions from the base portion (2a) in which the inner diameter of the inner surface of the partial arc shape is increased to the extension portion (2b) of the small inner diameter. This is in consideration of the fact that the cylindrical portion (T ') of the crimp terminal (T) fixed to () is larger than the outer diameter of the wire. In this example, the length of the extension portion (2b) is about 1 / l of the “remaining” length of the plate-shaped main body portion (1) when the length corresponding to the base portion (2a) is disregarded. It is a composition that has reached the point of 2. As a result, it is possible to maintain sufficient flexibility of the wire end portion in the vicinity of the wire identification indicator (H) and also to secure the fixing strength of the display tool to the end portion.

FIGS. 5 and 6 show a single-piece display having a shape suitable for use in a case where the flexibility of bending of the electric wire end near the display tool (H) is particularly desired. That is, the extension portion (2b) is made extremely short, and the length of the "remaining" portion of the plate-shaped main body portion (1) is about the same.
Although it is terminated at about 1/5, the tongue piece, the ear-like extension (10) and other points are the same as those in FIG.

On the contrary, in the embodiment of FIGS. 7 to 14, the flexibility of the wire end portion near the display tool (H) is not so desired, and the strong attachment of the display tool is strongly desired. (7th ~
(Fig. 9) is a case in which strips are continuously provided (Figs. 10 to 14). The extension portion (2b) has a length that extends over the entire length of the plate-shaped main body portion (1), but is configured as a band, that is, the shape of the tongue and the ear-shaped extension portion (10) and vertical bending. The part (10a) is the same as the above example.

On the back surface of the plate-shaped main body portion (1), the protrusion (1a) protruding at the location of the base (2a) is engaged with the pressure-bonding concave portion of the cylindrical portion (T ') of the pressure-bonding terminal (T). In this case, the display tool (H) is prevented from falling off.

Various modifications are made to the above invention, for example, a tongue piece (10b) having the same shape and the same size as the tongue piece (7) in the connecting portion (6) as shown by a broken line in FIG. Ear extensions (10)
If they are provided so as to project from both outer edges, there is an advantage that the feeding to the above device can be performed more reliably up to the end of the band. Regarding the display unit alone, the inner and outer diameters of the partial arcuate inner surface of the protruding piece (2) are made uniform over the entire length, and the tubular portion of the crimping terminal is avoided when it is wrapped with a resin coating in advance. Or a tapered wide cutout area is provided at both ends of the clearance so that the display tool holding and expanding holder (11) of the prior application device can be installed in either forward or reverse direction. (1
It is also possible to adopt a configuration such that it can be inserted into the aligned tip of 1).

<Effects of the Invention> According to the present invention, a projecting piece having a shape capable of surrounding and flexing substantially the entire circumference of the wire end is projectingly provided from the plate-shaped main body part, and the width between the tip edges thereof is the minimum necessary. A plurality of single display devices each having a thin and reversibly expandable / reducible clearance are provided in series, tongues are arranged in rows along both outer edges, and an ear-like extension is connected from the end of the single display device. A strip of the installed configuration is provided. Therefore, the belt-shaped body can be accurately moved straight by an appropriate sprocket-shaped feeding member without any fear of skewing, and moreover, it is possible to surely supply the above-mentioned prior application device up to the single display device at the end. It is very significant that it contributes to the improvement of the efficiency of the work of mounting the display tool in the case of.

In particular, since the tongue piece is provided at the connecting portion, the tongue piece is automatically cut off at the same time as the connecting portion when the single piece is cut off. There is no possibility of adversely affecting the use and action, and since the ear-like extension has substantially the same width and height as the main body of the belt, conveyance to the display tool on the end side of the belt,
The band-shaped body can be gripped when handling such as printing and cutting and handling in the same manner as for the part from the starting end side of the band-shaped body to the middle of the length direction. Since it is possible to effectively use all the display devices having a band-shaped structure without needing them, there are advantages such as improved work efficiency and elimination of waste.

As described above, the indicator strip of the present invention has an extremely simple structure, but after the identification symbol is attached to the surface of the plate-like body, the indicator alone can be steadily and highly efficiently attached to the end portions of many wires. Can be installed in sequence, and its practical value is enormous.
