Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire swelling preventing jig which is inserted into, for example, a connection terminal of a connector and prevents the electric wire drawn in a horizontal direction perpendicular to the insertion direction from swelling.

[0002]

2. Description of the Related Art When wiring a wire harness to an automobile, for example, as shown in FIG. 6, a wire harness 103 connected to a mating connector 101a of a connection box 101 via a connector 102 is inserted in a terminal insertion direction of the connector 102. There is a case where the electric wire 104 is pulled out and arranged in the lateral direction Y orthogonal to X.

[0003] A wire harness 103 for a connector 102 for pulling out such an electric wire in the horizontal direction (hereinafter, such a connector is also referred to as a horizontal connector) is formed as shown in FIG. That is, a box jig 105 having a connector mounting portion 105b having an upper surface opening provided at an upper end of a shaft portion 105a erected on a wire harness assembly drawing board 109 is used, and a connector is mounted on the connector mounting portion 105b. 102 is set such that the terminal accommodating chamber 102a faces upward. After that, the connection terminal 106 attached to the tip of the electric wire 104 is inserted into the terminal accommodating chamber 102a from above, and the electric wire 104 is bent in the lateral direction Y, and the middle of the electric wire 104 is bound by a tape to be formed. .

[0004] Thereafter, the connector 102 is detached from the connector mounting portion 105b and fitted and connected to a predetermined connection box.

When the electric wire 104 is bent in the lateral direction Y, the electric wire 104 is pulled in the lateral direction from the position where the electric wire 104 comes out of the connector 102, and the connector 10
The connection terminal 106 in the second terminal accommodating chamber 102a may be inclined. In this state, if the connection terminals 106 are bound in a tape, that is, taped, the connection terminals 106 will not be in a proper posture, and there is a problem that the connection terminals 106 cannot be easily fitted when attached to the mating connector of the automobile.

Accordingly, a technique has been proposed in which a spacer is mounted on the box jig so as to be positioned above the connector set in the box jig, and the electric wire in a portion protruding upward from the spacer is laterally bent. (Japanese Unexamined Patent Publication No. 09-180853)
issue). In the case of this proposed technique, the height dimension between the lower end of the wire portion (referred to as a parallel wire portion) protruding from the side-projecting connector parallel to the connector upper surface and the connector upper surface becomes substantially equal to the thickness of the spacer. Therefore, the connection terminal can be held in the normal posture.

[0007]

However, in the prior art including the above-mentioned proposed technology, the height from the upper surface of the connector to the upper end of the parallel electric wire portion is not regulated, so that there are the following problems.

That is, since the above-described electric wire is taped in a state where the position of the lower end of the parallel electric wire portion is regulated, the electric wire swells so that the height from the connector 102 increases as time elapses after the taping. . For this reason, when the horizontal connector 102 is used, for example, in an engine room, the wires swelled with the passage of time as described above interfere with metal pipes and the like arranged in the vicinity thereof and rub against each other. The coating of the electric wire is damaged, and the core wire is exposed, and there is a possibility that an electric trouble occurs.

The present invention has been made to solve such problems of the prior art, and can suppress the inclination of the connection terminal connected to the connector, and furthermore, the connection terminal is pulled out from the connector in the lateral direction. An object of the present invention is to provide an electric wire swelling prevention jig capable of suppressing the electric wire from expanding with time.

[0010]

According to the present invention, there is provided a jig for preventing swelling of an electric wire, comprising a box-shaped jig having a connector mounting portion having an upper surface opening on which a connector is set by insertion from above.

A sliding member having a parallel portion parallel to the upper surface of the connector set on the box jig is slidably mounted in a direction along the upper surface of the connector, and the parallel member slides along the sliding member. Between the lower end of the parallel electric wire portion parallel to the upper surface of the connector and the upper surface of the connector, it is possible to secure a gap for suppressing the connection terminal from being inclined by sliding of the parallel portion, and Order to the distance between the upper end and the connector top surface of said parallel electric wire portion to be equal to or less than a predetermined size,
The distance between the lower surface of the parallel portion and the upper surface of the connector is regulated.

In the electric wire swelling preventing jig of the present invention, a connector is set on a connector mounting portion of a box jig, and a connection terminal attached to the electric wire is inserted from above into a terminal accommodating chamber of the connector. Thereafter, when the slide member is slid toward the connector side with respect to the box jig, the slide causes the parallel portion to bend the electric wire in the slide direction. At this time, since the interval between the lower surface of the parallel portion and the upper surface of the connector is regulated, the connection terminal is located between the lower end of the parallel electric wire portion pressed by the lower surface of the parallel portion and made parallel to the upper surface of the connector and the upper surface of the connector. A gap for suppressing the inclination due to the sliding of the parallel portion is secured, and the distance between the upper end of the parallel electric wire portion and the upper surface of the connector is equal to or less than a predetermined dimension. Therefore, by performing taping in this state, it is possible to suppress the wire drawn laterally from the connector from expanding over time, and to suppress the connection terminal connected to the connector from tilting. Can be.

Further, it is preferable that a curved portion for preventing damage to the electric wire is provided at an end of the parallel portion on the side where the electric wire is bent in the lateral direction. By doing this,
There is no danger that the parallel portion of the slide member will damage the wires. In addition, you may make it provide a bending part also in the edge part by the side opposite to the side which bends an electric wire laterally.

In the wire bulging prevention jig according to the present invention, the slide member has a pair of legs along the side surface of the box jig on both sides of the parallel portion, and the tips of both legs are box jigs. The tool may be bent inward so as to enter long grooves formed on two opposing side surfaces of the tool, and the bent front ends may be slidable along the long grooves.

In this configuration, it is only necessary to mount the slide member with the tip of the leg portion of the slide member inserted into the long groove of the box jig. Inexpensively can be made.

The wire swelling prevention jig of the present invention sets a connector on the connector mounting portion of a box-shaped box jig having a connector mounting portion having an upper surface opening into which a connector is set by insertion from above. An electric wire swelling prevention jig for forming a wire harness for inserting a connection terminal from above into a terminal accommodating chamber opened on an upper surface of the connector, and bending a wire to which the connection terminal is attached in a lateral direction, It has a pressing portion provided near the box jig and provided so as to be able to contact and separate from the upper surface of the connector set in the box jig, and a swing lever, and the swing operation of the swing lever A mechanical movement mechanism for moving the pressing portion toward and away from the connector, and a parallel electric wire pressed by a lower surface of the pressing portion to be parallel to the upper surface of the connector when the pressing portion approaches the upper surface of the connector by the operating force. The lower end of the part and the Between the upper end of the parallel electric wire portion and the upper surface of the connector can be reduced to a predetermined dimension or less. In order to achieve this, a stop member for stopping the mechanical motion mechanism when the distance between the pressing portion and the connector upper surface reaches a certain size is provided.

In the electric wire swelling prevention jig of the present invention, a connector is set on a connector mounting portion of a box jig, and a connection terminal attached to the electric wire is inserted from above into a terminal accommodating chamber of the connector. Subsequently, the electric wire is held in a state where the electric wire is slightly or largely bent in a desired bending direction, and then the swing lever is operated so that the pressing portion approaches the connector. Thereby, the pressing portion approaches the connector, and bends the electric wire in a desired bending direction. In this situation, when the distance between the pressing portion and the upper surface of the connector becomes constant, the stop member stops the mechanical movement mechanism. In this stopped state, a gap is formed between the lower end of the parallel electric wire portion parallel to the upper surface of the connector at the lower surface of the pressing portion and the upper surface of the connector to suppress the connection terminal from being inclined by the pressing of the pressing portion. The distance between the upper end of the parallel electric wire portion and the upper surface of the connector is not more than a predetermined dimension. Therefore, by performing taping in this state, it is possible to suppress the wire drawn laterally from the connector from expanding over time, and to suppress the inclination of the connection terminal connected to the connector. Can be.
