Force) type connector.

2. Description of the Related Art Conventionally, as an example of this type of connector, the one disclosed in Japanese Patent Application Laid-Open No. 57-105986 can be cited. This connector is provided with one connector having a plurality of contacts each having a contact portion opened in a U-shaped cross section on the tip side, and a plurality of mating contacts inserted into and contacting the contact portions of each of these contacts. Made up of the other mating connector. When connecting with this connector, as a first operation, both connectors are brought close to each other in the axial direction in which each contact extends, and each connector in one connector has an opening at the contact portion of each contact, and each mating side in the other mating connector. After inserting the tips of the contacts, the second operation is to move both connectors relative to each other in a direction perpendicular to the axial direction of the contacts, so that the tips are respectively attached to one of the three-sided walls of the contacts. Contact is made.

As another example, the connector disclosed in Japanese Examined Patent Publication No. 3-28024 has a plurality of contacts each having a contact portion having a U-shaped cross-section on the tip side and a bent portion extending from the contact portion in the middle. It is composed of one connector and the other mating connector having a plurality of mating contacts that are inserted and locked into the contact portions of these contacts. When connecting with this connector, by mating both connectors close to each other in the axial direction in which each contact extends, each mating side of the other mating connector having a size larger than the inner diameter of each contact part. One part of each contact is locked to each contact part, and each contact of both connectors is brought into contact with each other by receiving the restoring force from the deformed bent part of each contact of one connector. That is, in the case of this connector, connection can be performed by one operation.

Further, as another example, the connector disclosed in Japanese Patent Laid-Open No. 6-89764 includes a plurality of arcuate contacts having protrusions protruding from both ends, and allows each contact to buckle. From one connector having an opening for holding the connector, and the other pair of mating connectors each having a plurality of mating contacts that are sandwiched from both sides and are pressed into contact with the protrusions of the contacts. Made of When connecting with this connector, connect both sides of one connector to the other so that the mating contacts of the other pair of mating connectors abut against the protrusions at both ends of each contact of the one connector. By sandwiching and pressing and fixing with the mating connector, the contacts of both connectors are brought into contact with each other by receiving the restoring force from the deformed arcuate portion of each contact of one connector.

[0005]

In the case of the connector of the above-mentioned example, two steps of operation are required to connect each connector, and the structure for that is complicated, and it takes time and effort to operate and manufacture. There's a problem.

In addition, in the case of the connector of another example, while the connector has an advantage that the connection operation can be easily performed, each contact of one connector has a bent portion and extends in the axial direction, so that the connector is bent. There is a disadvantage that the size of the connector in the extending direction of the part becomes large.

Further, in the case of the connector of another example, the bow-shaped contacts of one connector are provided in the opening and are brought into contact with the mating contacts of the other mating connector by the restoring force when they are buckled. Therefore, there is a problem in that the buckled state of each arcuate contact varies, and the contact state of each contact in both connectors tends to become unstable.

The present invention has been made to solve such a problem, and its technical problem is that the operation and the manufacturing are not troublesome and the contact of the contact is improved without having unnecessary dimensions. It is to provide a connector that can be stably performed at a density.

According to the present invention, one connector in which a plurality of contacts having open contact portions are arranged in parallel, and the connector is inserted from the openings of the plurality of contacts to contact the contact portions. It is composed of the other mating connector in which a plurality of mating contacts extending in the uniaxial direction are arranged side by side, and one connector and the other mating connector are fitted close to each other in the uniaxial direction at the tips of the mating contacts. A buckling-deformable connector is obtained, which is brought into abutting contact with the contact portion when mated and the intermediate portion is buckled and deformed in a direction perpendicular to the uniaxial direction. In this buckling-deformable connector, it is preferable that, with respect to the plurality of mating contacts, an end opposite to the tip is fixed to the body of the mating connector.

Further, according to the present invention, a pair of connectors in which a plurality of contacts each having an opened contact portion are arranged side by side, and both ends are brought into contact with the contact portion by being inserted between the openings of the pair of connectors. It consists of multiple mating contacts that extend in the uniaxial direction, and both ends of the mating contacts contact the contact parts when a pair of connectors are fitted close to each other in the extending direction of the contacts. A buckling-deformable connector is obtained which is brought into contact with each other and whose middle portion is buckled and deformed in a direction perpendicular to the extending direction.

Further, according to the present invention, in any one of the above-mentioned buckling deformation type connectors, the middle portions of the plurality of mating contacts are partially bent in advance to prescribe the direction of buckling deformation. It is possible to obtain a buckling deformable connector having a plurality of mating contacts, or a buckling deformable connector having a plurality of mating contacts in which conductors are stacked on the surface of an elastic insulator.

The connector includes a connector and a plurality of mating contacts 40 that are inserted between the openings of each of these connectors and extend in one axial direction so that both ends contact the contact parts. Regarding each mating contact 40 here,
Both ends of the contacts come into contact with the contact parts when a pair of connectors are fitted close to each other in the extending direction of the contacts 3 and 3 ', and the middle part thereof is in a direction perpendicular to the extending direction. It is designed to be buckled and deformed.

Even if each mating contact 40 is formed as a separate body as described above, when each of the contacts 3 and 3'and the mating contact 40 are brought into contact with each other, the same as in the case described with reference to FIG. Both ends of each mating contact 40 come into contact with the contact portions of the contacts 3 and 3'at three points indicated by the tips of the three arrows, and the drag forces F1 and F2 from the contact portions along the directions of the arrows. , F3, and as a result, both ends of each mating contact 40 are contacted with each contact 3, 3 '.
It will be contacted to the contacting part in a very stable state.

By the way, each of the above-mentioned mating contacts 4,
The shapes of 4'and 40 may be plate shapes, but regarding the mode of the buckling deformation and the restoring force, the mating contacts 4, 4 '
Fine adjustment can be made by forming the conductors 4'and 40 on the surface of an elastic insulator having a desired elasticity.
