Abstract

PROBLEM TO BE SOLVED: To provide a compact-sized connector for a cable which is superior in operability for inserting a cable therein and can prevent an actuator from falling out. SOLUTION: In a connector for a cable in relation to the invention, a first contact 20 among two kinds of contacts is provided with a first engagement and support part 23 and a first contact part 21. A first cam part 41 of an actuator 40 comprises a first cam-pressing plane for pressing the rear side of a cable 50 and an engagement cam semicircular plane, which engages the first engagement and support part 23 of the first contact 20. Since the first contact 20 comprises a spring part 24, which can be deformed elastically, the first cam- pressing plane is forced in the direction of the depth of the cable 50 by the first engagement and support part 23. A second engagement support part 13 of a second contact 10 engages with an engagement cam part 44, and as a result, it is guided in the direction of the depth of the cable 50. In other words, the second engagement and support part 13 is engaged with the engagement cam part 44. As a result, the engagement cam part 44 prevents the second contact 10 from moving in the direction of the depth of the cable 50 by more than a fixed distance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a flexible printed circuit (FPC).
The present invention relates to a rotary cable connector that opens and closes an actuator suitable for connecting a sheet-like cable such as a printed circuit to a substrate.

[0002]

2. Description of the Related Art This type of FPC (Flexible Printed Circular)
In the cable connector, the cable is inserted into the opening of the housing together with the substrate after the actuator is opened, and the cable is pressed into the housing while the actuator is closed.

As conventional examples, there are Japanese Utility Model Laid-Open Publication No. Hei 6-77186 and Japanese Patent Laid-Open Publication No. Hei 1-315976.

[0004]

However, referring to FIG. 3 of Japanese Utility Model Laid-Open Publication No. Hei 6-77186, the rotation support portion 5 will be described.
And the engaging means of the concave portion 11 of the pressing member (actuator) 7, the concave portion 11
It is easy to move in the direction of pulling out.

[0005] In the case of a cable connector having a large number of cores and extending in the longitudinal direction, when inserting and fitting a cable, the concave portion 11 cannot go under the rotation supporting portion 5 and it is difficult to insert the cable. There are drawbacks.

In the structure disclosed in Japanese Patent Application Laid-Open No. 1-315976, FIG. 2 and FIG. Since the cam (actuator) 100 shown in FIG. 5 is supported only by the holes 84 on both sides of the housing 4, there is a drawback that the cam (actuator) 100 easily comes off and comes off.

[0007] In addition, there are many demands for miniaturization by narrowing the pitch of connectors.

It is therefore an object of the present invention to provide a small-sized cable connector which has excellent cable operability and can prevent the actuator from coming off.

[0009]

To solve the problems of the present invention, the following means are adopted.

(1) A cable connector for receiving a cable having one surface and an opposite surface, wherein the contact has a contact portion facing the one surface and an engaging pivotal portion facing the opposite surface, and the contact A housing having a housing for inserting and holding the contact in a predetermined direction, and an actuator having a cam portion engaging with the engagement pivot portion, and having an actuator for pressing the cable against the contact portion. Comprises first and second contacts having first and second contact portions and first and second engagement pivot portions, wherein the cam portion engages with the first and second engagement pivot portions. A first cam pressing surface for pressing an opposite surface of the cable; and an engagement engaging with a first engagement pivot of the first contact. A cam surface, and the actuator is provided with a through hole adjacent to the first engagement cam surface so as to orbit around the first cam pressing surface and the engagement cam surface, whereby the The second cam portion is rotatably supported by a first engagement pivot portion of one contact, the second cam portion presses an opposite surface of the cable, and the second cam pivot portion of the second contact receives the second cam push portion. A cable connector comprising:

(2) The cable connector according to (1), wherein the first and second engagement pivots include a spring portion that is elastically deformable in a thickness direction of the cable. Connector.

(3) In the cable connector according to (1), in a state in which the cable is not connected, the engagement cam portion contacts the second engagement pivot portion to reduce the thickness of the cable. A connector for a cable, which is guided in a direction.

(4) In the cable connector described in (1), since the engaging cam portion is an engaging cam notch that receives and engages with the second engaging pivot portion, the second cam pressing portion is provided. Is formed as a reduced pressing portion, whereby when the actuator is in a closed state, the second pivot portion abuts a portion near the reduced pressing portion adjacent to the engaging cam notch. Thus, the second contact locks the actuator.

[0014]

(1) The first engagement pivot of the first contact is disposed in the through hole of the actuator. One surface, that is, the lower surface of the cable is in contact with and contacts the first contact portion of the first contact. On the other hand, the opposite surface, that is, the upper surface, of the cable is pressed by the first cam pressing surface of the first cam portion adjacent to the through hole of the actuator. In this way, in the through hole of the actuator, the first contact acts to wrap the first cam portion with the first engagement pivot.

On the other hand, the second contact also has a second contact portion and a second engagement pivot. The second engagement pivot is disposed on the engagement cam. The engagement cam portion is a small groove that opens (releases) in one direction.

With respect to the second contact, one surface, that is, the lower surface, of the cable is in contact with and contacts the second contact portion. On the other hand, the opposite surface, that is, the upper surface, of the cable is pressed by the second cam pressing portion of the second cam portion. In this way, the second engagement pivot of the second contact fits into the engagement cam of the actuator. Thereby, the second engagement pivot portion acts to support the curved surface forming the engagement cam portion.

Incidentally, if the connector has a large number of contacts extending in the longitudinal direction, it is better to alternately arrange two types of contacts. Since the through-hole may be formed only at the position corresponding to the first contact as compared with the connector including all the first contacts, the cable connector of the present invention acts so that the pitch can be reduced.

(2) The respective spring portions of the contacts cooperate in directions approaching each other. Thereby, each contact can be reduced in the thickness direction of the cable, and the connector can be downsized.

(3) When the actuator is released before the cable is inserted, the second engagement pivotal portion acts so as to fit into the engagement cam portion. As a result, the engagement cam portion restricts the second contact from moving more than a certain distance in the thickness direction of the cable.

To reiterate, the second engagement pivot is
It engages with and engages with the engaging cam portion. Therefore, before insertion of the cable, positioning (positioning) can be performed in the thickness direction of the cable. As a result, it acts to improve the cable insertability.

(4) An engaging cam notch may be used instead of the engaging cam that opens (releases) in one direction. The engagement cam notch has a substantially L shape that is released in two directions.

In a state where the actuator is closed, the second pivot portion acts so as to abut on a portion (inner edge portion) of the engaging cam notch near the reduced pressing portion. Thus, the second contact locks the actuator.
