Description

  The present invention relates to a wire-conditioning jig used to align terminal conductor wires extending from an end of a cable used in various electronic devices.

  In general, a wide variety of cables are used as internal and external wirings for information devices such as personal computers and electronic devices such as home appliances. When such a cable is electrically connected to each conductor part such as another cable or a board, a connector wired to the terminal part of the cable is usually interposed. When connecting to a portion, first, a plurality of terminal conductor wires extending from the end of the cable body are aligned so as to be substantially parallel to each other, and the aligned terminal conductors are arranged. A wire is inserted into the inner side of the connector so as to be fixed to the connection portion.

  At this time, the terminal conductor wires extending from the end of the cable main body described above are in an aligned state that is essentially aligned in parallel, but the state of delivery etc. before connecting the connectors Depending on the case, for example, as shown in FIG. 6, a plurality of terminal conductor wires 1, 1,... May be in a broken state, or may be bent due to pitch deviation or solder pool. In many cases, it is often difficult to connect to the connection portion inside the connector.

  Therefore, in the prior art, it is the present situation that the terminal conductor wires 1 are straightened to be in parallel with each other, that is, the wire alignment operation is manually performed one by one. Is a cause of productivity reduction because it requires a lot of labor. In addition, when the wire-alignment work is insufficient, a terminal failure may occur, resulting in poor connection, and the cable may be cut when the terminal failure is corrected. It is a problem in both productivity. Furthermore, although various jigs as found in the following patent documents have been proposed, the terminal conductor wires are not arranged in parallel with the regular shape.

In the operation position, it is pressed onto the set fixing base 23e provided on the base substrate 21 side. Then, in the state where the pressing plate 23c is pressed from the upper side to the set fixing base 23e via the laminate tape 14 at the cable end described above, the holding action between the set fixing base 23e and the set fixing base 23e described above. The laminated tape 14 of the terminal conductor wire 12 extending from the restriction groove portion 22a is sandwiched, and the terminal conductor wire 12 is positioned and fixed.

  Operation gripping arms 23d and 23d are attached to such a pressing plate 23c so as to protrude in both directions, and the user grips each of the operation gripping arms 23d to swing the pressing plate 23c. Is to be done.

  On the other hand, a fixed column 24 is erected substantially vertically on the back side portion of the base substrate 21 described above. One end portion of a base support 25 formed in a beam shape is fixed at an appropriate height position in the fixed support 24. The base support 25 extends from the fixed support 24 in a cantilevered manner so as to be in a substantially parallel state on the upper side of the base substrate 21 described above. An operating shaft 26a that constitutes the moving operation mechanism 26 is attached to the extended tip portion so as to be reciprocally movable in the vertical direction.

  The operation shaft 26a is configured to move up and down by the turning operation of the up and down operation lever 26b provided on the base support 25 described above. A support bracket 26c is fixed to the operation shaft 26a at the tip of the upward projecting portion from the base support 25, and a coil spring 26d is interposed between the support bracket 26c and the base support 25. The operation shaft 26a is mounted coaxially. The operation shaft 26a is constantly pushed upward by the upward biasing force of the coil spring 26d.

  Further, a stopper pin 26e protruding downward toward the base support 25 is attached to the support bracket 26c described above, and a lower end portion of the stopper pin 26e is located on the base support 25. On the other hand, the lowest position of the operation shaft 26a described above is regulated at a position abutted from above.

  That is, when the operation shaft 26a is lowered by the above-described rotation operation of the up / down operation lever 26b, the lower end portion of the operation shaft 26a protrudes downward from the lower surface side of the base support body 25. A fixing plate 26f is attached to the lower end portion of the operation shaft 26a so as to protrude from the operation shaft 26a in a cantilever manner. The fixing plate 26f is attached so as to extend to a position directly above the set base 22, and a heating means is provided at an extending end portion of the fixing plate 26f, that is, a position directly above the set base 22. 27 is fixed so as to extend in a substantially vertical direction.

  The heating support 27a is formed from an elongated, substantially cylindrical member, and an appropriate heater (not shown) is built in the heating support 27a, and the lower end side of the heating support 27a. The shaping pressurizing body 28 is continuously provided via the connecting shaft 27b. And the heat_generation | fever from the heater of the heating support body 27a mentioned above is transmitted to the shaping pressurization body 28 through a connection shaft.

  At this time, the shaping pressurizing body 28 is formed of a plate-like member disposed at a position directly above the restriction groove portion 22a of the set base 22, and the vertical operation lever 26b serving as the movement operation mechanism 26 described above.
