DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connector, and more particularly to a connector with a cam member which can completely fit a housing of a mating connector and its own housing with a small force by operating a sliding cam member. Things.

[0002]

2. Description of the Related Art A connector provided with a slide type cam member of this type is disclosed, for example, in Japanese Utility Model Laid-Open No. 6-11275 or 6-5.
As disclosed in Japanese Patent No. 4255, the cam member can be moved from a preparatory position where it can be engaged with the housing of the mating connector in the temporary mating position to a position where the housing of the mating connector can be moved to the fully mating position. By sliding to the position, the housing of the mating connector and its own housing can be completely fitted with a small force.

[0003]

By the way, in order to reliably perform the connection work with the mating connector, it is necessary for the worker to quickly slide the cam member to the completed position during the connection work. It is preferable to be able to confirm. However, conventional connectors with cam members are:
It was difficult for the operator to check whether the cam member was slid to the completion position. Therefore, the connection work is difficult to be performed, and the connection work is likely to be completed without sliding the cam member to the completion position. Particularly, depending on the technical field, the two connectors may be connected in a groping state, and in such a case, it is more difficult to confirm that the cam member has been moved to the completion position.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible for an operator to quickly and surely move a slide-type cam member to a completion position to surely connect with a mating connector. It is another object of the present invention to provide a connector with a cam member that can be confirmed.

[0005]

In order to achieve the above object, a connector with a cam member according to the present invention comprises a housing and a slide-type cam member attached to the housing, and each of the cam members has a cam groove. The housing and the mating connector have two formed walls extending in parallel to each other and a side wall connecting the both walls, and by sliding the cam member from a preparation position to a completion position. In the connector with a cam member capable of completely fitting with the housing, the cam member extends from the side wall portion in the sliding direction of the cam member, and the cam member moves to the completion position when the cam member moves to the completion position. An elastic piece located outside the housing and having a first surface extending substantially parallel to the sliding direction and elastically deformable in a direction substantially perpendicular to the sliding direction is provided. Is, in the housing, the contact portion having a sliding direction and a second surface extending substantially parallel is provided on one of the elastic piece and the contact portion,
When the cam member slides from the preparation position to the completion position, a convex portion that bends and deforms the elastic piece in the substantially right-angle direction while slidingly contacting the other, and on the other hand, the cam member moves to the completion position. A concave portion for receiving the convex portion at the time of movement and elastically restoring the elastic piece is provided, and the second surface is provided on the first surface of the restored elastic piece.
Is provided at a position where the contact sound is generated by contact with the surface.

[0006] The above-mentioned concave portion includes a step-shaped one and a hole-shaped one in addition to a normal concave one.

[0007]

According to the connector with the cam member of the present invention, when the slide type cam member moves from the preparation position to the completion position, the first surface of the elastic piece and the first surface of the contact portion have the same. The two surfaces make contact with each other when the elastic pieces are elastically restored and emit a contact sound. Therefore, the worker who performs the connection work with the mating connector can quickly and surely confirm whether or not the cam member has moved to the completion position by distinguishing whether or not this contact sound has occurred. .

Since the elastic piece and the abutting portion are provided at a portion located outside the housing, the abutting sound is easily transmitted, and the operator can easily confirm the occurrence of the abutting sound. In addition, the vibration when the first surface of the elastic piece and the second surface of the contact portion come into contact with the housing and the cam member is transmitted to the housing and the cam member together with the generation of the contact sound. It is also possible to confirm that the cam member has moved to the completion position also by feeling in the hand.

Next, a second embodiment of the present invention will be described. FIG. 5 is an exploded perspective view of a connector with a cam member according to a second embodiment of the present invention, and FIG. 6 is a sectional view showing a state in which an elastic piece of the cam member and a contact portion of a housing are engaged with each other.

The connector 10A of the present embodiment has a cam member 30A.
Only the structure of the elastic piece 40A and the contact portion 50A of the housing 12A is different from the first embodiment. The elastic piece 40A of the cam member 30A extends in the direction B in the drawing from the upper end of the side wall 33 of the cam member 30A, and extends above the upper wall 31 substantially parallel to the upper wall 31. The elastic piece 40A has a first surface 41 on a side facing the upper wall portion 31, and a convex portion 42 having a slope 42a protruding downward is formed on the first surface.

On the other hand, the contact portion 50A of the housing 12A has only a rear end portion connected to the upper surface of the housing 12A via the connecting wall 53.
This embodiment is significantly different from the first embodiment in that it is connected to the second member 12a and can be elastically deformed so as to be largely bent in the vertical direction similarly to the elastic piece 40A of the cam member 30A. In the central portion of the contact portion 50A, as in the first embodiment, a hole for receiving and engaging with the convex portion 42 of the elastic piece 40A.
A second surface 55 is formed on the upper surface side of the contact portion 50A, while the second surface 55 that makes contact with the first surface of the elastic piece 40A when engaged is formed.

In the first embodiment, the elastic piece 40 enters the lower side of the contact portion 50, and the convex portion 42 is configured to engage with the hole portion 54 from the lower side. As shown in FIG. 6, the elastic piece 40A overlaps above the contact portion 50A,
42 is formed to engage with the hole 54 from above.
The functions of the elastic piece 40A and the contact portion 50A are the same as in the first embodiment, and a detailed description is omitted.

In this embodiment, since the contact portion 50A is configured to be elastically deformable, the first surface 41 of the elastic piece 40A and the second surface 55 of the contact portion 50A may be in contact with each other. There is an advantage that a contact sound is easily generated. When the engagement between the elastic piece 40A and the contact portion 50A that are engaged with each other is released, the elastic piece 40A is pressed downward from above, and both the elastic piece 40A and the contact portion 50A are moved downward. Bend into the elastic piece 40
The engagement between the convex portion 42 of A and the hole 54 of the contact portion 50A may be released.

Next, a third embodiment of the present invention will be described. FIG. 7 is an exploded perspective view of a connector with a cam member according to a third embodiment of the present invention.

The connector 10B of the present embodiment has a cam member 30B.
The elastic piece 40B is formed at a position displaced rearward in the figure from the position above the upper wall portion 31 of the cam member 30B, and the contact portion 50B of the housing 12B corresponds to the elastic piece 40B.
The only difference from the first embodiment is that it is formed at a position shifted rearward in the figure from the position above the upper surface 12a of the upper surface 12B. The functions of the elastic piece 40B and the contact portion 50B are the same as in the first embodiment, and a detailed description thereof will be omitted.

Although the embodiment of the present invention has been described above, the connector with a cam member of the present invention is not limited to the specific embodiment of the embodiment, and various changes can be made.

For example, in each of the above embodiments, the convex portion is formed on the elastic side and the hole is formed on the contact portion side. However, a hole may be provided on the elastic side and the convex portion may be formed on the contact portion side. In addition, the hole may be an ordinary concave (hollow) shape.

Also, contrary to the above embodiment, an elastic piece which can be elastically deformed may be formed on the housing side, and a contact portion may be formed on the cam member side.
