2. Description of the Related Art This type of connector is disclosed, for example, in Japanese Patent Laid-Open No.
It is disclosed in Japanese Patent No. 35828, Japanese Patent Laid-Open No. 9-92411, and the like. These connectors are FFC and FPC.
A plurality of contacts each having a contact portion facing one surface of a plate-like object and a supporting portion facing the opposite surface of the plate-like object, an insulator holding the contacts, and a contact part of the plate-like object with this contact. Includes a manipulator for pressure contact with. In order to obtain the connection, first, the plate-like object is inserted from the front of the connector between the contact portion of the contact and the cam portion of the operator. Next, the operator is rotated, and the plate member is brought into pressure contact with the contact portion of the contact by the cam portion of the operator.

Further, for example, Japanese Patent Application Laid-Open No. 7-142130 discloses an example of a structure in which an operator is rotatably assembled to an insulator. With this structure, the shaft portion provided on the operator is inserted into a semicircular recess formed on the rear surface of the insulator. According to this structure,
After assembly, you can expect stable rotation of the operator.

[0004]

However, the assembly of the operator from the rear is hindered by the shape of the insulator, so that there is a problem in the assembling property of the operator. That is, when the operator is assembled from the front, the insulator and the operator have a special structure in order to allow the shaft portion to be inserted into the recess, for example, the structure that allows the insulator to be elastically deformable and the operator can be expanded and contracted. It is necessary to have a structure to do so. These structures are disadvantageous for miniaturization of the connector.

Therefore, an object of the present invention is to provide a plate-shaped connector having a structure which is stable in operation and advantageous in size reduction.

BEST MODE FOR CARRYING OUT THE INVENTION A plate-shaped connector according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. This plate-shaped connector is an insulator 12 that receives an FPC 11 as one of the plate-shaped objects to be connected.
This insulator 12 includes a large number of conductive contacts 13 arranged in a row at a predetermined pitch on the left and right and fixedly held, and an operator 14 for pressing the FPC 11 to the contact 13.

The contact 13 integrally includes a contact portion 15 facing one surface of the FPC 11 and a support portion 16 facing the opposite surface of the FPC 11. That is, the contact portion 15 and the support portion 16 are opposed to each other in the up-down direction with a space therebetween. The supporting portion 16 has a concave portion 1 at a position facing the contact portion 15.
7 are formed.

A cable insertion portion 18 is formed on the insulator 12 so as to match the distance between the contact portion 15 and the support portion 16. The FPC 11 is inserted into the cable insertion portion 18. The distance between the contact portion 15 and the support portion 16 is FPC1.
Since it is sufficiently larger than the thickness dimension of No. 1, the FPC 11 can be easily inserted.

The operator 14 is a plate-shaped member that is long in the left and right, and has a large number of holes 19 formed in a one-to-one correspondence with the supporting portions 16 of the contacts 13. With the support portion 16 inserted in these holes 19, the operator 14 is moved to the insulator 1
Assemble to 2. The hole 19 is formed to have a size such that the supporting portion 16 is inserted with a gap.

The operator 14 has a cam portion 21 located in the recess 17 of the support portion 16 when assembled to the insulator 12. The cam portion 21 has a cross-section having a shape in which two semicircles are connected by two straight lines, but various modifications are possible. In this way, the operator 14 is engaged with the supporting portion 16 so as to be rotatable around the cam portion 21.

Furthermore, at the left and right ends of the operator 14,
As shown in FIG. 3, a shaft portion 22 is provided. on the other hand,
The insulator 12 has a guide groove 23 extending forward and backward,
The engaging groove 2 extending upward from the rear of the guide groove 23
4 and. The guide groove 23 serves to guide the shaft portion 22 to introduce the cam portion 21 between the contact portion 15 and the support portion 16 when the operator 14 is assembled. The engagement groove 24 allows the cam portion 21 to move toward the support portion 16 side from a notch formed in the wall portion 12 a that defines the upper side surface of the guide groove 23. As a result, the engagement groove 24 and the support portion 16 cooperate to support the operator 14 rotatably.

With reference to FIGS. 4 and 5, the work of assembling the operating element 14 to the insulator 12 will be described. First, the manipulator 14 is positioned in front of the insulator 12 as shown by a chain line in FIG. 5, and the manipulator 14 is moved rearward while guiding the shaft portion 22 to the guide groove 23. As a result of this work, the cam portion 21 contacts the contact 1 as shown by the solid line in FIG.
3 is introduced between the contactor 15 and the supporting portion 16. When the shaft portion 22 reaches the rear portion of the guide groove 23, the operator 14 is pulled up and the shaft portion 22 is inserted into the engagement groove 24. Thus,
The plate connector shown in FIGS. 1 and 2 is obtained.

Next, with reference to FIG. 6 and FIG. 7, the connecting work of the FPC 11 by the plate-shaped connector will be described. When the operator 14 is in the open first position as shown in FIG. 6, the cam portion 21 is held in a state of lying in the recess 17. As a result, a gap wider than the thickness dimension of the FPC 11 is maintained between the contact portion 15 of the contact 13 and the cam portion 21. Therefore, when the operator 14 is in the first position, the FPC 11 can be easily inserted into the cable insertion portion 18 of the insulator 12.

When the operator 14 is rotated from the first position to the second position shown in FIG. 7 with the FPC 11 inserted in the cable insertion portion 18, the FPC 11 rotates the cam portion 21 of the operator 14. It is pressed by the movement. As a result, the FPC 11 is pressed against the contact portion 15 with the elastic deformation of the contact portion 15 of the contact 13, and an electrical connection is obtained. When the operating element 14 is in the fitted state (that is, the second position), the cam 21 receives a force for closing the operating element 14 by the supporting portion 16 and the contact portion 15 via the FPC 11. Therefore, when in the fitted state, the operator 14 does not easily move in the disengagement direction (that is, the direction toward the second position).

According to this plate-shaped connector, it is possible to obtain a sufficient contact force with a small operating force by utilizing the boosting force of the lever, so that it is possible to maintain an appropriate operability even if the number of cores is increased to some extent. . Further, since the cam portion 21 of the operator 14 is restricted from moving upward, leftward and rightward by the support portion 16 of the contact 13 and the engaging groove 24 of the insulator 12, the cam portion is increased even if the number of cores is increased. 21 is not swept out due to friction with the FPC 11, and all cores can be reliably connected.

[0020]

As described above, according to the connector for plate-like object of the present invention, the operating force can be small even when the number of cores of the plate-like object is large. In addition, the operation is reliable even when the number of cores of the plate-like object is large. Furthermore, the reliability of the connection is increased.
It is also advantageous in terms of downsizing.
