Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fixture for a connector used for connecting electric wiring for an automobile or the like.

[Conventional technology]

In FIG. 8, brackets a and b are provided with connectors c and d which are connected to each other. The connector c has a ring-shaped elastic support piece e on the upper, lower, left and right sides, and is attached by engaging the ring-shaped elastic support piece e with the support groove a ₁ of the bracket a (FIG. 9).

When the connector c is connected to the opposing connector d, the ring-shaped elastic support piece e absorbs the dimensional tolerance, so that the connector can be easily connected (Japanese Utility Model Laid-Open No. 142345/1989).

However, this structure cannot absorb the dimensional tolerances of the brackets a and b in the front-rear direction.

[Problems to be solved by the device]

The present invention focuses on the above points, and provides a connector mounting tool capable of absorbing dimensional tolerances in the vertical and horizontal directions and the front and rear directions.

[Means for Solving the Problems]

To achieve the above object, the connector with a fixture of the present invention comprises a pair of connectors that are fitted to each other, and one of the connectors is an elastic bracket for supporting a connector, which includes a mating direction extension piece and a cross direction extension piece. And the other connector has an elastic bracket for supporting a connector, which comprises an extension piece in the fitting direction and an extension piece in the cross direction displaced by approximately 90 ° from the extension piece in the cross direction.

[Action]

The cross-direction extension pieces of the pair of brackets are displaced in the left-right direction or the vertical direction, and the fitting-direction extension pieces are displaced in the front-rear direction.

〔Example〕

In FIG. 1, A is a synthetic resin female connector, and B is a synthetic resin male connector, which are fitted to each other.

The female connector A is integrally provided with a crank-shaped elastic bracket C for supporting the connector, and the male connector B is integrally provided with an elastic bracket D for supporting the crank-shaped connector.

The bracket C includes a fitting extension piece 2 extending rearward from one side wall 1 of the connector A, a crossing direction extension piece 3 extending laterally from a rear end of the fitting direction extension piece 2, and an outer end of the crossing direction extension piece 3. The bracket D includes a fitting direction extension piece 4 extending rearward, and the bracket D extends laterally from a rear end of one side wall 5 of the connector B, and extends rearward from an outer end of the crossing direction extension piece 6. Fitting direction extension piece 7 and fitting direction extension piece 7
And a cross direction extension piece 8 extending further outward from the rear end. Mounting holes for the mating direction extension piece 4 and the crossing direction extension piece 8
4a and 8a are drilled and fixed to a vehicle body, a mounting block or the like with screws 9.

In Brats C and D of connectors A and B that are fitted to each other,
The cross direction fitting piece 2 and the cross direction fitting piece 6 are in a positional relationship of being displaced by 90 °, and the connector A has a front-rear direction p and a left-right direction q.
The connector B can be displaced in the front-rear direction p and the vertical direction r.

When the connectors A and B are fitted together, the fitting guide rod 10 projecting from the connector A is engaged with the fitting guide hole 11 of the connector B, and the brackets C and D are positioned vertically, horizontally and in the front-rear direction. Adjust to absorb the dimensional tolerance. At the time of fitting, the fitting guide rod 10 penetrates the connector B, so that complete fitting can be confirmed.

FIG. 2 shows a fitted state of the connectors A and B when the dimensional tolerance in the front-rear direction is positive, and FIG. 3 shows a fitted state when the dimensional tolerance in the front-rear direction is negative.

4, 5, 6, and 7 show a connector supporting elastic bracket D integrally provided with the male connector B.
A modification of (FIG. 1) is shown.

In the case of FIG. 4, the bracket D ₁ includes a fitting direction extension piece 7 extending rearward from one side wall 5 of the connector B, and a cross direction extension piece extending laterally outward from the rear end of the fitting direction extension piece 7. 6
And a fitting direction extension piece 7'extending rearward from the outer end of the crossing direction extension piece 6. In the case of FIG. 5, the bracket D ₂ is a fitting direction extension piece 7 extending rearward from one side wall 5 of the connector B, and a cross direction extension piece extending laterally inward from the rear end of the fitting direction extension piece 7. 6 and a fitting direction extension piece 7'extending rearward from the inner end of the crossing direction extension piece 6.

In the case of FIG. 6, the bracket D ₃ includes a fitting direction extension piece 7 extending rearward from one side wall 5 of the connector B, and a cross direction extension piece extending laterally outward from the rear end of the fitting direction extension piece 7. 6
And a fitting direction extension piece 7'extending forward from the outside of the cross direction extension piece 6.

In the case of FIG. 7, the racket D ₄ is a crosswise extension piece 6 extending laterally from the rear end of one side wall 5 of the connector B, and a fitting direction extension extending from the outer end of the crosswise extension piece 6 to the front side. It comprises a piece 7 and a cross direction extension piece 8 which extends further outward from the front end of the fitting direction extension piece 7.

In these cases, the connector B can be displaced in the front-rear direction P and the up-down direction r, as described above.

In addition, the connector support elastic bracket C of the female connector A
Also, various combinations of the fitting direction extension pieces 2 and 4 and the crossing direction extension piece 3 are possible.

[Effect of device]

As described above, the present invention comprises a pair of connectors fitted to each other, one connector having a connector supporting elastic bracket comprising a fitting direction extension piece and a crossing direction extension piece, and the other connector. Since it has a connector supporting elastic bracket consisting of a mating direction extension piece and the crossing direction extension piece in a state of being displaced by approximately 90 ° with the crossing direction extension piece,
The bracket can absorb the dimensional tolerances in the up-down, left-right, and front-rear directions when the pair of connectors are coupled, and can easily fit the pair of connectors.
