The edge body applies a preload to the contact terminal and connects the object to be contacted with this? It is a connector that is inserted diagonally into the edge body without any insertion force, and by making the wave guide means horizontal, it clamps the contact terminal or the object to be contacted and establishes an electrical connection.It is easy to insert, and the contact terminal Since the preliminary direction 1 is applied to , a strong clamping force can be obtained by rotating the object to be contacted by a slight angle.

[Fields of use of Yutojo]

The present invention relates to a connector into which a plug portion (edge portion) of a contact object for double-sided contact, such as a gate board, is inserted without any insertion force.

With the increasing density and multipolarity of contact terminals, no-insertion-force type connectors with zero insertion force have recently been proposed and put into practical use.
The amount used tends to increase more and more. [Problems to be solved by conventional techniques and inventions] JP-A-54-137664, JP-A-54-13766
As disclosed in Publication No. 2 and Japanese Patent Application Laid-Open No. 137663/1989, etc., conventional connectors of this type have a structure in which a cam and a moving body for elastically deforming the contact terminals are built into an insulator, and the number of parts is reduced. There are many parts, and the assembly becomes complicated.
It was expensive.

In addition, in conventional connectors, the contact part of the contact terminal is only pressed against the contact part of the object to be contacted, and there is almost no sliding contact, so the wiping effect of the contact is small, and there is a high risk of chips etc. intervening or adhering to the contact part. There were problems such as contact failure.

In order to solve these problems, the present invention proposed a connector filed on June 22, 1985, but in this proposal, the contact terminal is P! with all its spring force applied. Because it was held in a box, a large angle of rotation was required to insert the object into contact, level it, and apply the desired clamping force, and the multiple contact terminals were not aligned, causing them to collide and deform when the object was inserted. There was a fear that it would happen.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a plurality of contact terminals each having a bent piece at a tip portion, a contact portion, a fixed portion at an intermediate portion, and a terminal portion at a rear end portion; The contact insertion portion of the bent piece locking portion and the contact insertion portion of the contacted body, which fixes the fixed portion by leading out the contact portion and the terminal portion so that the contact portion and the terminal portion are fixed, and applies a preload to the contact terminal by locking the bent piece. P! has an insertion port into which it is inserted. The body is stomatous,
comprising at least a rotatable guide means for guiding the object to be contacted to the insertion opening of the insulator, and the contact terminals arranged in two rows have their contact portions positioned above and below with the insertion opening sandwiched between them,
The bending piece is installed so that a preload is applied to the bending piece locking part of the insulator, and the contact part on one side is set so that the upper and lower contact parts are displaced in the direction along the insertion direction of the object to be contacted. is arranged so as to be able to contact one side of the contact insertion part at a far position, and the contact part on the other side is arranged so as to be able to come into contact with the other side of the contact insertion part at a nearby position, and the contact part is arranged so as to be able to come into contact with the other side of the contact insertion part at a position close to the contact insertion part, and the contact part is arranged so as to be able to contact one side of the contact insertion part at a position close to the other side of the contact insertion part. By inserting the contact insertion part into the insertion opening of the insulator from an oblique direction and rotating the guide plate horizontally, the contact part is elastically deformed and the contact insertion part is clamped with a desired contact pressure. [Operation] According to the above means, a series of insertion/attachment operations (insertion,
In order to achieve contact using the rotary action, the structure of the connector itself is simple, such as installing a rotatable guide means, and the contact can be made by elastically deforming the contact terminals. Sliding contact is performed or attended. Since the preload 1 is applied to the contact terminal, a desired clamping force can be obtained by rotating the object to be contacted by a slight angle.

The bent piece 2 at the tip is locked by the bent piece locking portion 7VC@ provided on the insulator 6, so that a preload is applied to the contact portion 3°3'9. The nine contact portions 3.3' are shifted from each other, and the contact pattern (Fig. (not shown), and the contact portion 3 on the other side can contact a contact pattern (not shown) formed in the other direction of the printed board 10 at a position near the insertion end of the printed board 10. .

However, due to the relief @ of the insulator 6, the fixed position of the fixed part 4 is located closer to the fixed position of the fixed part 4', and as a result, the lead-out lengths of the contact parts 4 and 4' are made almost equal, and the stiffness of both is reduced. Formed to match.

Next, the guide means of this embodiment has a through hole 12 into which the cassette 9 can be inserted, and the lower and side surfaces of the guide means extend through the insulator 6.
