Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention has a slit that can be expanded over the entire length in the longitudinal direction of the central part of a cylindrical part formed on the back surface of a rectangular plate part made of synthetic resin. The present invention relates to an electric wire end identification piece attaching device for attaching an existing identification piece to an electric wire end, and particularly to a manual electric wire end identification piece attaching device that can be applied before or after crimping a conductive terminal to the electric wire end. .

<Prior art> A large number of wire connection methods have been widely used in which a large number of electric wires that have been fitted with conductive terminals are collectively attached to a pair of male and female connectors, and the electric connection between the plurality of electric wires can be made simultaneously. ing. In addition, it is often necessary to connect many wires in a complicated state. In these cases, the work of attaching some kind of mark to each wire end after or before crimping the conductive terminal is widely performed as an identification means for preventing mistakes in the wire connection work, but it is conventionally complicated with fingertips. Due to the difficult manual work that required movement, it was extremely complicated and inefficient to attach the identification tool to the end of a large number of wires.

<Problems to be Solved by the Invention> Therefore, the present applicant has continued to devise and improve a wire end identification piece suitable for mechanical attachment. In particular, the purpose of the present invention is to manually An object of the present invention is to provide a device capable of reliably and quickly attaching the identification piece to the end of the electric wire by a simple operation. However, the wire end portion identification piece applied to the device of the present invention has a slit that can be expanded over the entire length in the central portion longitudinal direction of the cylindrical portion formed on the back surface of the rectangular plate portion made of synthetic resin. There is a need.

The tubular portion may extend the entire length of the plate-shaped portion, or may be half or less than half of the length.

<Means for Solving the Problems> In order to achieve this object, the wire end identification piece attaching device of the present invention has a slider at the tip of a slider that is extruded in the guide hole of the main body toward its tip. The identification piece gripping body that is pushed by the guide hole and can move back and forth on the extension line of the guide hole, and the electric wire receiving body that keeps a constant distance from the main body are arranged. A pair of holders with which a claw capable of approaching and retreating in the shape of a letter are abutted, and the claw is inserted into a slit over the entire length of the cylindrical portion of the identification piece to widen the slit. In a device having a pressing piece facing the claw of the slider and connected to the slider tip through a spring, the main body is pivotally attached to the grip at the base, and is swung toward the grip. With a manual arm A pinion that engages with a rack having an arcuate tip end of the manual arm and a rack provided at the rear portion of the slider is rotatably supported by the wall of the guide hole, and the identification piece gripping body and the electric wire receiver are provided. The body is held or formed by an extension frame, and the frame is detachably connected to the main body.

The extension frame is mounted such that it can rotate with respect to the main body, and the center line of the identification piece gripping body on the frame matches or is at least parallel to the center line of the slider of the main body. It is preferable.

The slits are formed by, for example, projecting leg-shaped pieces having a U-shaped cross-section from each side edge of the plate-shaped portion and interposing a gap between the tips of the U-shaped portions. It may be formed by a method. The point is that the width of the void is expanded by an external force having an appropriate strength and elastically restored to the original width by removing the external force.

In one embodiment of the device of the present invention, the size and overall shape are similar to those of a pistol for the convenience of handling, but other shapes may be used as long as the above-mentioned components are included.

<Operation> Each part of the wire end identification piece attaching device of the present invention operates as follows.

At the retracted position, the wire end identification is made to the aligned claws of the pair of holders, which are held in the posture of forcibly abutting each other against the biasing force of the spring by the restraining means in the retracted position. Insert the slit in the piece and load the piece into the holder. On the other hand, the end of the electric wire to which the identification piece is attached is placed on the electric wire receiver. In this state, when the manual arm is pulled toward the grip portion against the biasing means, the slider is advanced by the rack mechanism, and the identification piece gripping body having the holder causes the extension frame to receive the electric wire receiver. Sliding towards the body. In the process, first, the holders gradually released from the restraint means are expanded by the elastic force of the springs in the directions away from each other. Therefore, the pair of claws inserted into the slit of the identification piece are also separated from each other, and the tubular portion of the identification piece is opened slightly larger than the outer diameter of the wire end portion.

When the slider is further advanced, the identification piece is half-fitted to the end of the wire while receiving resistance due to the presence of the crimp terminal having an outer diameter slightly larger than the end of the wire, and at the same time, the restraint of the restraint means to the holder is complete. The holder and the pawl forming a part thereof are completely separated from the wire end and the identification piece. When the manual arm is more strongly attracted to the grip, the pressing piece receives the force of the slider tip through the spring, and the plate-like surface side of the identification piece (the side on which the identification mark is printed).
Is strongly pressed to the end of the electric wire, and the fitting of the identification piece to the end of the electric wire is completed. After that, when the hand force applied to the manual arm is released, the manual arm automatically returns to the original position by the biasing means, and the force at the time of the return causes the holder to retract, so that Both claws are also retracted to the original position where they contact each other again.

In short, for one wire end, mount it on the receiving body, load the identification piece on the claw of the holder, and then pull the manual arm to the grip part to attach the identification piece. Can be performed, and thereafter, this operation only needs to be repeated as many times as necessary.

In particular, in a configuration that is a feature of the present invention, that is, in a configuration in which the identification piece gripping body and the electric wire receiving body are held or formed on an extension frame and the frame is detachably connected to the main body portion, the identification piece A cylindrical piece disposed at the rear part of the grip body is removably attached to the front end concave portion of the slider on the main body side, and a pair of retainer tip hooks pivotally supported on both sides of the tip of the main body and projecting forward Since it is detachably engaged with the circumferential groove formed in the base portion of the extension frame, the extension frame is strongly pushed in the direction of separating from the main body portion while the hook portion is detached from the circumferential groove. By pulling, the spring-loaded small balls on the inner surface of the recess at the front end of the slider can be forcibly disengaged from the circumferential groove of the cylindrical piece at the rear end of the identification piece holder. As a result, the extension frame can be separated from the main body portion and can be replaced with another extension frame. In that case, first, the extension frame to be newly attached should be applied while opening the retainer to the outside of the main body portion against the biasing force, and the rear end cylindrical piece should be strongly pushed into the recess at the front end of the slider. As a result, the spring-loaded small spheres on the inner surface of the recess are elastically fitted into the peripheral grooves on the outer peripheral surface of the cylindrical piece for reconnection.

<Embodiment> An embodiment will be described below with reference to the drawings. An electric wire end identification piece (S) applied to the device of the present invention is a rectangular plate portion (S) made of synthetic resin as shown in FIGS. 8 to 10.

The quadrangular prism-shaped rear portion (5b) of the slider (5) is slidably tightly fitted in the quadrangular cylindrical guide hole (4). The identification piece gripping body (6) has a cylindrical piece (11c) sandwiched and fixed to the rear portion of the bottom plate (11a) and the lid piece (11b), and is inserted and fixed from the rear end of the cylindrical piece (11c). A spring (10) is interposed between the front end of the piece (11d) and the rear end of the pressing piece (11) in a compressed state, and the cylindrical piece (11d) is
c) is inserted into the front cylindrical concave portion of the tip cylindrical portion (5a) of the slider (5), and the small sphere (11e) held by the inner surface of the concave portion is held by the spring of the cylindrical piece (11c). The cylindrical piece (11c) is elastically fitted in the circumferential groove, and the cylindrical piece (11c) is rotatable relative to the tip cylindrical portion (5a) and cannot be pulled out from the cylindrical portion (5a) by an external force less than the spring biasing force. It is a retained structure. The number (11f) is a stopper that prevents the pressing piece (11) from coming off the front.

In the main body (H), the base (13
There is provided a manual arm (13) pivotally attached (13b) in (a) and swingable by an attractive force toward the grip (12). This swinging is performed against the elastic force of a spring (not shown), for example, a spring interposed between the rear end portion (13c) of the manual arm (13) and the grip portion (12). Then, a pinion (16) constantly meshing with the rack (14) having the arcuate tip end of the manual arm (13) and the rack (15) provided on the lower surface of the quadrangular prism-shaped rear part (5b) of the slider (5) is provided. Is rotatably supported by the wall of the guide hole (4) (16a).

An important feature of the device of the present invention is that the identification piece gripping body (6) is held by the extension frame (F), and the wire receiving body (7) is formed as a part of the extension frame (F). The extension frame (F) is removable from the main body (H) and is connected to the main body so as to be rotatable relative to the main body (arrow A in FIG. 2). Therefore, not only can the identification piece be attached easily regardless of the relative angle between the user's hand angle and the end of the wire and the terminal, but also the identification piece or the end of the wire with different specifications such as dimensions. When dealing with, it is possible to replace it with another extension frame with specifications according to this.

The above-mentioned relative rotatable connection is made by the identification piece gripping body (6).
The cylindrical piece (11c) is attached to the front end recess of the slider (5) on the main body side so as to be relatively rotatable and separable, as shown in FIG. 1, and as shown in FIG. (H) It was pivotally supported (17a) on both sides of the tip and projected forward 1
This is because the distal end hook portions (17b) of the pair of retainers (17) are slidably engaged with the circumferential groove (18) formed in the base portion of the extension frame (F) by the spring biasing force ( (See FIG. 4, arrow Q).

A spring biasing means (not shown) is provided at the base of the retainer (17), and the retainer is disengaged from the circumferential groove (18) against the elastic force of the means, and then the spring is pressed as described above. The frame (F) can be removed from the main body (H) by strongly pulling the extension frame (F) in order to forcibly disengage the biasing small ball (11e) from the circumferential groove of the cylindrical piece (11c). .
Therefore, it is possible to replace with another suitable extension frame depending on the specifications of the wire end portion.

(F) An insertion hole (19) is formed in the bottom plate. A cylindrical identification piece loading device (20) is rotatably fixed near the insertion hole (19) of the bottom plate. Specifically, as shown in FIG. 4, a spindle (21a) projecting from the disc body (21) and having a split tip is inserted into the central hole (22) of the loader (20), A small recess (21b) at the tip of the support shaft (21a) is fitted into a small protrusion (23a) on the inner surface of the blind hole (23) of the bottom plate (see arrow P in FIG. 4). The identification pieces (S) can be housed in the small chambers (24) arranged at equal intervals around the support shaft (21). Since the loading tool (20) is made of a transparent material, for example, transparent synthetic resin, the identification piece (S) in the small chamber (24) is rotated by hand and the identification piece (S) is inserted into the insertion hole (19). After visually recognizing that the disc is aligned, the identification piece (S) is directed toward the holder (9) by the push rod (25) penetrating the spring chamber (25a) provided on the outer surface side of the disc body (21). ) Stick out. As a result, the identification piece is loaded into the gripping body (6) with the pair of claws (8), (8) being cut into the slit (3). Spring chamber (25
a) Since the internal spring (25b) biases the push rod (25) outward, the rod is automatically returned to the position shown in FIG. 1 after the identification piece is projected.

After the identification piece (S) is thus loaded, or before the wire end portion (D) is placed on the wire receiving body (7), the receiving body (7) is attached to the extension frame (F). On a vertical plate (7a) protruding in parallel with the holder (9) at the tip side, a pedestal (7b) and a top receiving plate (7d) having a recess (7c) flush with it are formed. The extension frame bottom plate is provided with a crimp terminal receiving hole (7e) at a position corresponding to the recess (7c).

If the identification piece (S) and the wire end portion (D) are loaded as described above, the two will face each other in the position shown in FIG. 9 in the state shown in FIG. After that, when the manual arm (13) is pulled as shown by the arrow (Y), the slider (5) moves forward as shown by the arrow (T) as shown in FIG. 6 and reaches the state of FIG. 7 as described above. As shown in FIG. 10, the identification piece (S) is attached to the wire end (D), the details of which are as described in the section <Action>.

When the holder (9) is in the retracted position in FIG. 5, the restraining member (26) prevents the spring (not shown) from expanding in the direction of the arrow (R). When 6) advances and the side surface of the holder (9) separates from the restraining member (26), the spring expands it as shown in FIG. 6, and the identification piece (S).
Enlarge the gap of the slit (3). When the holder (6) is retracted, the arcuate guide surface (26a) of the member (26) forces the holder to the posture shown in FIG. 5 while resisting the elasticity of the spring (not shown). And restore smoothly.

For the above-described embodiment of the present invention, for example, without providing a special grip portion, the cylindrical portion of the main body surrounding the slider guide hole is used as the grip portion, and the manual arm is pivotally attached to one end side of the cylindrical portion. In addition, the pinion has a two-stage gear shape and adopts a structure in which the displacement of the manual arm is amplified and transmitted to the slider, and as a result, the overall appearance shape is a kind of thick rod-shaped body, and various modifications are made. Can be added.
