る。 Referring to FIG. 1, there is shown a cross-section of a flat cable 1 running in a direction perpendicular to the plane of the paper, and a substantially U-shaped pressure contact portion 2 of a connector forming a connection therewith. Flat cable 1 is
A cable core 1' is coated with an insulating material 3,
The contact portion 2 has sharp blades 2', 2' which bite into the insulator and connect to the cable core 1'. At this time, if the pitch between the cable cores 1' and 1' is equal to the pitch a on the center side of the contact part 2, the connection to the flat cable 1 is completed, but as shown in FIG. If there is a pitch deviation in b as shown in a, the cable core wire 1' may be cut, resulting in incomplete connection. Such an error may occur due to a pitch shift in the cable core or a pitch shift in the contact portion.

を固定する固着部８が形成されている。 FIG. 2a shows a perspective view of the connector 4 according to the invention. The connector 4 includes a rod-shaped fitting part 5 that connects to another member such as a printed board or a socket having substantially the same shape as this connector, and a substantially U-shaped pressure contact part 2.
These two parts are integrally connected by a flexible flat plate-shaped connecting part 6, and above the fitting part 5 there is a cylindrical part 7 for reinforcement and A fixing portion 8 is formed in the connector to fix the connector by biting into an insulating block to be described later.

の動きは、第２図ａにおいては矢印ｉで示す方向
の動きである。 The connector 4 is assembled into a block 9 shown partially cut away in FIG. 2b, on which the flat cable 1 shown in FIG. 1 is placed and pushed downward. Then, cable core wire 1'
and the contact portion 2 of the connector are connected. At this time, as shown in FIG. 3a, it is assumed that there is a pitch shift indicated by b in the figure. At this time, as the flat cable 1 is lowered, the contact part 2 moves as shown by the arrow i in FIG.
If the bull also moves as shown by arrow ii, this pitch deviation will be corrected. Contact part 2 shown in Figure 3b
The movement is in the direction indicated by arrow i in FIG. 2a.

なしうる。 Such movement of the contact portion 2 is made possible by the bending of the connecting portion 6. That is, referring to FIG. 2a, when there is a movement of the contact part 2 in the direction of arrow i parallel to that surface, the connecting part moves downward as shown by arrow ii, and vice versa. . Thus, with the connector 4 according to the present invention, the core wire 1' and the contact portion 2 can be accurately connected despite the pitch error of the flat cable.

度を高くすることは難しい。 By the way, when the connector 4 is assembled to the block 9 [FIG. 2b], the pitch a between the contact parts 2 and the pitch c between the fitting part 5 are different. In FIG. 2b, for the connector 4 in the center of the block 9, the center of the contact part 2 and the center of the fitting part 5 coincide with each other in the direction perpendicular to the flat cable 1, but as they move away from the center, ,
The deviation between the two centers becomes large. As mentioned above, this misalignment was corrected by the elastic bending of the connecting part 6 of the connector 4, but as a result, the contact part 2 twisted or fell down, making it difficult to improve the pitch accuracy of the contact part. .

の機能を十分に発揮することが可能となる。 In order to solve this problem, as shown in FIG. 4, a contact hole 10 having a width indicated by d in the figure is formed in the block 9 that houses the connector 4, and the contact portion 2 is inserted into the hole 10. Referring to the diagram, make it movable in the left and right directions. Here, if the width of the lower part of the contact part is e, the contact part 2 is
At its bottom it is movable within a distance of (de). By forming such a contact hole 10 in the block 8, the contact portion 2 can fully perform its original function.

とが理解されよう。 Returning to FIG. 3, when there is a pitch deviation b between the cable core 1' and the contact part 2, as shown in FIG. 3, as the flat cable 1 is pushed down, the cable core 1' is indicated by arrow ii in Figure 3b.
The contact portion 2 moves as shown by arrow i, and accurate pressure contact is performed. This pitch deviation b is caused by the lower part of the cable core 1'
Since it is sufficient to hit the blade 2' of the contact portion 2, it will be understood that a pitch error of up to b<a/2 is allowed.

他の部材との接続についても問題がある。 In the embodiment described above, the pitch deviation of the contact part 2 and the flat cable can be accommodated, but there is a problem with the fitting part 5. The fitting part 5 is
Typically, a socket 12 as shown in FIG. 5 is fitted to form a connection. There is also a problem with connection of such a fitting part 5 with other members.

影響を及ぼす。 As mentioned above, the connector 4 is fixed in the block 9 by its fastening part 8. By the way, the block 9 is also subject to some pitch error in the formation of the hole for accommodating the connector 4, and this error increases as the number of core wires in the flat cable increases. Therefore, such a pitch error affects the insertion and removal of the fitting portion 5, and becomes an obstacle to accurate formation of the connection portion. Alternatively, it causes an increase in insertion force and removal force that impairs operability. In the illustrated embodiment, the fitting part 5 is formed into a pin shape as a male contact, but the fitting part 5 is formed as a female contact, that is, a socket, and the mating member is not a socket but a male contact (pin). In some cases. In such a case, a high degree of accuracy is required for the positioning of both, and the pitch error of the holes in the block described above has a serious effect.

ロツク９との組立体の信頼性が向上する。 In order to absorb the pitch error that affects the fitting part 5, a flexible part 11 corresponding to the above-mentioned connecting part 6 is formed between the cylindrical part 7 and the fixed part 8 in the connector 4. Thereby, for example, the fitting part 5
Even if it hits the left part of socket 12,
As the socket 12 rises or the block 9 moves downwards, the mating part 5 moves to the right in the figure and enters the center of the socket 12, making insertion easy and ensuring accurate positioning. be done. In order to enable such movement of the fitting part 5, the flexible part 11 is formed to have sufficient springiness.
By doing so, it becomes possible to absorb the pitch error on the side of the fitting portion 5 of the connector 4, and the reliability of the assembly of the connector 4 and the block 9 is improved.
