関し、殊にICリード等がピン端子である場合に
好適に用いられる接触子に係る。[Detailed Description of the Invention] The present invention relates to a contactor used in an IC socket or the like, and particularly to a contactor suitably used when the IC lead or the like is a pin terminal.

圧のバラツキを招来しがちとなる。 Many of the contacts used in IC sockets, etc. are of the type that are equipped with a pair of elastic contact pieces, and an IC lead is inserted between the opposing surfaces of both contact pieces to achieve a pressure contact. When the lead is a pin terminal with a circular cross section, the contact between the smooth surface and the circular surface causes the pin terminal to slide sideways, the elastic contact piece torsion, etc., causing the contact point to move out of its normal position. This tends to lead to variations in contact pressure for each pin terminal.

が望まれている。 In addition, if there is contact between a smooth surface (contact piece) and a circular surface (pin terminal), the cleaning effect on the contact surface cannot be expected to be very effective, and furthermore, as mentioned above, the pin terminal will be displaced in the escape direction and the contact pressure will increase. Since contact pressure is weakened and contact pressure cannot be expected to concentrate at sharp parts, it is desired to provide a contact that enables more reliable contact, in response to the trend toward miniaturization of pin terminals and contact pieces. ing.

is arranged to face the terminal holding groove 6, and similarly to the terminal holding groove 6, extends in the pin terminal insertion direction, and the pin terminal 8 is disposed between the edges 11 of the ends of both terminal holding pieces 10. A terminal clamping gap 12 is formed which is narrower than the diameter of the terminal.

The contact piece 1 waits in an open state with respect to the contact piece 2 depending on the usage example, and after the pin terminal 8 is inserted, it closes and contacts the side surface of the pin terminal.

Preferably, each terminal holding piece 10 and the gap 12 are arranged symmetrically with respect to one end of the diameter line R of the terminal 8 (the pin terminal generatrix that intersects with one end of the diameter line), as shown in FIG. , Similarly, the terminal holding grooves 6 are arranged symmetrically with respect to the other end of the same diameter line R (the pin terminal bus line that intersects with the other end of the diameter line), and apply side pressure in completely opposite directions to the pin. Balanced placement so that it can be applied to the terminal.

接触を得ることができる。 In the present invention, the pin terminal can be guided into the proper contact position with the contact piece by both the terminal retaining groove extending in the direction of insertion of the pin terminal and the V-shaped terminal retaining piece. In particular, by forming the terminal retaining groove by making one of the opposing surfaces a convex curved surface, even if there is some misalignment between the terminal retaining groove and the pin terminal, the contact piece can be corrected or the pin terminal can be elastically displaced while sliding into the retaining groove without easily slipping off. This eliminates the problem of the terminal slipping off and becoming difficult to return to its original position due to misalignment or variations in the accuracy of the cutting and raising of the retaining pieces, which occurs when, for example, terminal retaining pieces are cut and raised on both opposing surfaces, and allows the pin terminal to be securely captured and good four-point contact with the other terminal retaining piece can be obtained.

接触を図ることができる。 The present invention also prevents an increase in the distance between adjacent surfaces due to the formation of double-convex curved surfaces, such as when a contact piece is tilted forward or bent to make both opposing surfaces convexly curved to form a terminal gripping groove. It is possible to achieve stable contact by reducing the same distance as much as possible without inviting the enemy.

期待できる。 According to the present invention, the pin terminal is inserted into the terminal holding piece extending in the insertion direction of the pin terminal cut and raised in a V-shape from the opposing surface of one contact piece, and the pin terminal formed on the protruding curved surface of the opposing surface of the other contact piece. The terminal gripping groove extending in the direction cooperates to exert the above-mentioned relative positioning effect between the pin terminal and the contact piece, while the left and right edges of the terminal gripping piece and the terminal gripping groove move the pin terminal in the circumferential direction. Pressure contact is concentrated on the pin terminal surface at four locations, and a good cleaning effect on the pin terminal surface and highly reliable electrical contact can be expected.
