JP2571619Y2 - Connector with protective cap - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a connector with a protective cap used for connection of a wire harness or the like for an automobile.

[Conventional technology]

FIG. 5 shows a connector protective cap a made of synthetic resin, which has an opening b on one side of a rectangular parallelepiped case and an engaging portion d on the side of the opening b of the side wall c.

The cap a is fitted to an unused optional circuit connector f in the wire harness e to engage the engaging portion d with the lock portion g (FIG. 6).

The optional circuit connector f is to be connected to the vehicle-side device when the wire harness e is assembled to the vehicle. At this time, the operator presses the lock portion g with one hand to release the lock g while using another hand. The workability is poor because the cap a is pulled out.

Further, in this structure, the cap a may be attached to the connector f in a half-fitted state, which may drop off during transportation and lack dust protection and terminal protection, and the stable operation of the electric circuit in the vehicle assembled state. Will cause trouble.

[Problems to be solved by the invention]

The present invention pays attention to the above-mentioned drawbacks of the prior art, and ensures that the cap is completely fitted to the connector and that the cap can be easily removed from the connector.

[Means for solving the problem]

In order to achieve the above object, in the present invention, one of the connector and the protective cap fitted to each other is provided with a flexible spring piece which is urged toward the other, and when the connector and the protective cap are locked together. The flexible spring piece is deformed by accumulating a repulsive force in a direction in which the fitting is released by contact with a counterpart.

[Action]

During the lock connection process and the lock connection of the protective cap to the connector, the flexible spring piece acts on the protective cap in a direction of detaching from the connector.

〔Example〕

In FIG. 1, A is a protective cap for a connector made of synthetic resin, which has an opening 1a on one side of a main body 1 having a rectangular parallelepiped case shape, and a side plate 2 inside a cutout 2a of the side plate 2.
And a two-sided flexible spring piece 3 integrally formed with the other side plate portion 4 and a lock engagement portion 5. The flexible spring piece 3 is urged in the direction of the opening 1a.

B is a connector connected to the wire harness C,
Around the periphery, a contact portion 6 for the flexible spring piece 3 and a lock portion 7 for the lock engagement portion 5 are provided.

In the above configuration, when the cap A is fitted to the connector B, the flexible spring piece 3 comes into contact with the contact portion 6 and repels the fitting,
When the lock portion 7 and the engaging portion 5 are engaged with each other, the lock portion 7 is maintained in a completely locked state against a repulsive force in a direction in which the engagement is disengaged. This prevents the half-fitted state in which no is engaged (FIG. 2).

In the coupled state of the cap A and the connector B, when the lock portion 7 is detached from the engagement portion 5, the flexible spring piece 3 acts on the connector B so that the cap A automatically floats, and the cap A can be easily removed. Becomes

FIG. 3 shows a case where the connector B is integrally provided on the electric connection box D, and the surface 8 of the electric connection box D is a contact portion of the flexible spring piece 3.

In the embodiment shown in FIG. 4, the flexible spring piece 3 in the notch 2a of the protective cap A 'is omitted, and the double-ended flexible spring piece 3' is mounted on the protrusion 6 'around the connector B'. Are urged in the direction of fitting with the protective cap A '. At the time of coupling, the flexible spring piece 3 'is deformed while accumulating a repulsive force by contacting the contact portion 2b facing the notch 2a of the protective cap A'.

[Effect of the invention]

According to the present invention, as described above, one of the connector and the protective cap fitted to each other is provided with a flexible spring piece urged toward the other, and the flexible spring piece is locked when the connector and the protective cap are locked. Since the piece is deformed while accumulating a repulsive force in a direction in which the fitting is disengaged by contact with the other party, the operation of removing the protective cap from the connector is easy, and the protective cap is incompletely locked to the connector. Can be reliably prevented.
