2. Description of the Related Art Japanese Patent Laid-Open Publication No. Hei 6-77186 and Japanese Unexamined Patent Publication No. Hei 1-315
No. 976.

On the other hand, the applicant of the present invention (Japan Aviation Electronics Industry, Ltd.) filed a patent application No. 4 on January 11, 1999.
No. 558 has been filed.

There is also Japanese Patent Application Laid-Open No. 10-228957 of the present applicant (Japan Aviation Electronics Industry, Ltd.).

[0005]

However, in the conventional examples disclosed in Japanese Utility Model Laid-Open Publication No. 6-77186, Japanese Patent Laid-Open Publication No. 1-315976, and Japanese Patent Application No.
If the actuator is excessively rotated in the release direction to open the actuator to insert the (cable), there is a disadvantage that the actuator (slider) comes off.

In the structure disclosed in Japanese Patent Application Laid-Open No. 10-228957, the engaging projections 142 and the engaging grooves 145 are intertwined with each other and are kept in a released state.

However, this structure has an engaging projection 1
There is a disadvantage that the groove 42 and the engagement groove 145 are shaved when the actuator (slider) rotates.

Further, in the initial state, the released state in which the FPC insertion slot is opened is maintained.
When inserting an FPC (cable) into the PC insertion slot,
It is necessary to insert the actuator (slider) while holding it by hand in the released state, which impairs the workability.

[0009] Therefore, an object of the present invention is to prevent the actuator (slider) from coming off in any direction and not to cut off even if the actuator (slider) is rotated. To provide a connector.

[0010]

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

(1) A connector for a cable for receiving a cable having one surface and an opposite surface, wherein a contact having a contact portion facing the one surface and a pivot portion facing the opposite surface is provided, and the contact is provided in advance. In a cable connector having a housing that is inserted and held in a predetermined direction and an actuator that presses the cable against the contact portion, the pivot portion has a hook portion at a tip, and the hook portion includes The actuator is formed with a through-hole into which the pivot portion is inserted, and a cam portion having a protrusion and a dent adjacent to the through-hole, which protrudes in a direction orthogonal to the predetermined direction. The actuator includes a through-hole arrangement structure for arranging a pivot portion of the contact so as to penetrate the through-hole, and The actuator rotates while being supported / engaged by the pivot portion of the contact so that the lock portion fits into the depression and slides on the protrusion, and the actuator rotates in one of an open state and a closed state. When the actuator is connected to the cable.
The actuator displaces the pivot when closed
Let is by deforming the contact, before the cable connector, wherein the Kikururu Branch urges the cam portion to the cable.

(2) In the cable connector according to (1), a hook portion at a tip of the pivot portion has a concave shape, and the hook portion holds the protrusion while pivotally supporting the protrusion. A connector for a cable, wherein a pivot portion presses the cam portion as a result, thereby pressing the cam portion toward the cable, cooperating with the contact portion, and increasing a contact pressure.

[0013]

(1) The cam portion of the actuator has a recess formed adjacent to the through hole. The pivot portion of the contact is disposed in the through hole of the actuator, and the hook portion at the tip of the pivot portion of the contact is guided so as to fit into the recess of the cam portion of the actuator so as to support the cam portion of the actuator from above to below. If so, the actuator is in an open or released state.

When the actuator is rotated from the open state to the closed state, the hook at the tip of the pivot portion of the contact slides on the outer periphery of the protrusion. (2) In the case where the pivot portion has a concave portion, detachment of the actuator is further prevented when opening / closing and rotating the actuator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cable connector 11 according to a first embodiment of the present invention will be described with reference to FIGS.

The cable connector 11 includes the pivot 1
3 and a housing 19 for receiving a plurality of contacts 15 while receiving an FPC 17 which is a sheet-like cable having upper and lower surfaces.
An actuator 21 that opens and closes or rotates by being supported by the pivot portion 13 of the contact 15 implanted in the housing 19 to press the contact 17 against the contact 15.

The housing 19 has an upper opening for incorporating the actuator 21 and a number of holes 9 for inserting and implanting a number of contacts 15 in a predetermined direction, that is, from right to left in FIG. A right side opening formed; More specifically, bearing portions 20 are formed at both ends of the upper opening of the housing 19. Shafts 22 are provided at both ends of the actuator 21, and when assembled, the shafts 22 of the actuator 21 are housed in bearings 20 of the housing 19 from above the housing 19, respectively.

On the left side of the housing 19, a number of holes 10 for receiving a number of contacts 16 are arranged and formed so as to substantially correspond to the number of holes 9. The plurality of contacts 16 are inserted and arranged in the plurality of holes 10 so that the upper portion of the plurality of contacts 16 (see FIG. 2)
Slides when the FPC 17 is inserted from the left side (FIGS. 7 and 8). Note that the number of contacts 16 and the number of holes 10 may not be provided.

Referring to the features of the present invention, as shown in FIG. 2, the actuator 21 has a through hole 12 through which the pivot portion 13 of the contact 15 passes.
A cam portion 25 having a recess 23 and a protrusion 24 is formed adjacent to the through hole 12.

As shown in FIG. 2, the tip, that is, the hook portion, which constitutes the concave portion of the pivot portion 13 of the contact 15, protrudes in a direction perpendicular to a predetermined direction, that is, downward from above. Contact 1 in recess 23 of cam 25
The tip of the fifth pivot 13 is fitted and engaged. Pivot 13
Acts as a hook portion so as to fit into the recess 23 of the actuator 21 while supporting the cam portion 25 of the actuator 21 downward from above.

To reiterate, the pivot portion 13 of the contact 15 used in the cable connector 11 of the first embodiment of the present invention shown in FIGS. Is received.

The operation of the cable connector 11 according to the first embodiment of the present invention will be described.

The tip of the pivot 13 of the contact 15 is supported and engaged with the actuator 21 as a hook portion. In FIGS. 1 to 4, the tip of the pivot 13 of the contact 15 is This is an open state of the actuator 21 fitted in the recess 23.

Referring to FIG. 5 to FIG. 8, F
The PC 17 is inserted from the upper opening or the left side of the housing 19, and the actuator 21 is rotated to the left to close. At this time, the actuator 21 rotates while the hook portion at the distal end of the pivot portion 13 of the contact 15 slides on the protrusion 24, and the actuator 21 changes from the open state to the closed state. At this time, FIG. 2 is compared with FIG.
As is clear, the pivot 13 is displaced and contacts
15 is deformed. Therefore, the actuator 21
In the closed state, the pivot 1
3 urges the cam portion 25.

[0025]

As described above, the cable (FPC) connector according to the present invention has the actuator closed.
When the state is set, the pivot is biased toward the cam.
Is provided with the formation, regardless of the orientation of the even That arrangement be oriented any direction, an effect called Ru prevents the actuator from disengaging.

Further, if the hook portion at the tip of the pivot portion is formed in a concave shape, the protrusion of the cam portion of the actuator is supported while being pinched while being supported, so that the effect of completely preventing the actuator from coming off can be obtained. Play.
