Description

[Detailed description of the invention] [Industrial application field] The invention is mainly used for connection of electric wiring of an automobile, and a pair of opposed housings are fitted and detached by operating a cam member. It relates to an electrical connector.

[Conventional technology]

In FIG. 3, a is a female housing, b is a male housing, c is an operation cam member, and female and male housings a and b constituting a pair of connectors house terminal fittings respectively.

The hood portion a ₁ of the female housing a, sliding guide long hole a ₂ of the engagement operating cam member c combined covered thereto are formed, bifurcated frame-shaped fitting operating cam the inner surface of the member c, the drive projection c ₁ is provided projecting hood portion a ₁ engages with the sliding guide long hole a _2.

Then, on the outer surface facing each of the male housing b, the tapered driven groove b ₂ Following the introduction groove b ₁ entering of the drive projection c ₁ is formed.

In the above configuration, by facing the male housing b in the female housing a in a state where the engagement operating cam member c is positioned on one side of the female housing a, it is opposed to the introduction groove b ₁ to the drive protrusion c ₁ ( Figure 4 (a)), the driving protrusion c ₁ by pushing the male housing b from the introduction groove b ₁ is positioned at the inlet of the tapered driven groove b ₂ in this state (FIG. 4 (b)), the state in the drive projection c ₁ by moving the engagement operating cam member c to the right side in the drawing via a tapered driven groove b ₂ draws male housing therein, to connect both of the terminal fitting (Figure 4 (C)).

[Problems to be solved by the invention]

In the prior art described above, it is impossible to immediately combine the male housing b unless the cam member c for fitting operation is at the desired operation start position with respect to the female housing a.
An extra step for moving the fitting operation cam member c to a desired position before the fitting operation of the pair of housings is required.

The present invention has been made focusing on the above points,
Even when the fitting operation cam member is not at a predetermined desired operation start position, the fitting operation cam member is automatically driven by the initial fitting operation of the pair of opposing housings. It is possible to move to a desired position for operation start.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, a male housing and a female housing which are fitted to each other, and slide in a direction perpendicular to the fitting direction of the male housing in a sleeve of the female housing. A cam member for fitting operation provided so as to be able to be provided, and one of a pair of sliding plate portions of the facing outer surface of the male housing and the cam member for fitting operation in the fitting direction. A connector having a fitting operation cam groove that is inclined with respect to the other and a projection that engages with the fitting operation cam groove on the other side. The cam member for driving the cam member which is inclined is formed continuously with the cam groove for fitting operation.

〔Example〕

In FIG. 1, A is a female housing made of synthetic resin, B
Is a male housing made of synthetic resin, C is a cam member for fitting operation made of synthetic resin, and female and male housings A and B have
As is well known, each terminal fitting (not shown) is accommodated.

A cam member C for fitting operation is inserted into the sleeve 1 of the female housing A through the opening 2 on one side. The cam member C for fitting operation has a pair of sliding plates 4, 4 formed bifurcated with respect to the operating portion 3, and two projections 5 project from the inner surfaces of the sliding plates 4, 4. ing. The cam member C for fitting operation is fixed to the female housing A by the temporary lock piece 6 which has passed over the opening 2 by press fitting.
Has been prevented from leaving.

As is well known, tapered female and male housings A and B follow the introduction groove 7 on opposite outer surfaces of the male housing B.
A cam groove 8 that is inclined with respect to the fitting direction of the cam member is formed. Cam part 9
Are formed.

FIG. 2 (a) shows a case where the cam member C for fitting operation is deviated from the set position. In this state, when the male housing B is inserted into the body 1 of the female housing A, the cam member driving The cam portion 9 abuts against the protrusion 5, and the fitting operation cam member C is moved to the set position via the protrusion 5, and the protrusion 5 is positioned in the introduction groove 7 (FIG. 2 (b)).

Then, in this state, by pushing the cam member C for fitting operation by the operating part 3 moved to the set position, the male connector housing B is formed by the projection 5 through the cam groove 8.
In this state, the engaging portion 10 formed at the free end of the sliding plate portion 4 is engaged with the main lock piece 11 of the female housing A.

The cam groove 8 and the cam member 9 for driving the cam member may be provided on the cam member C for fitting operation, and the projection 5 may be provided on the male housing B.

〔effect〕

As described above, according to the present invention, a male housing and a female housing to be fitted to each other, and a fitting provided in a sleeve portion of the female housing so as to be slidable in a direction intersecting the fitting direction of the male housing. A cam member for mating operation, and is fitted to one of a pair of sliding plate portions of the male housing and a pair of sliding plate portions of the cam member for mating operation. A connector having a cam groove for mating operation and a projection provided on the other side for engaging with the cam groove for mating operation, wherein a cam member inclined with respect to the mating direction in front of the cam groove for mating operation. Since the driving cam portion is formed continuously with the fitting operation cam groove, when the fitting operation cam member is not at a desired setting position required for the fitting operation of the connector housing, , A pair of housings in the connector Since the fitting operation cam member can be automatically moved to the set position by the fitting initial operation, the number of manual operations required to move the fitting operation cam member to the desired setting position is reduced. Can be omitted.
