The object is to reduce the overall size by surrounding 0 and not exposing it to the outside. [Structure] An elastic metal thin plate is punched to form bottom wall 16 and upright side walls 18 and 20 on both sides thereof, and first and second extension portions 26 and 28 bent inward from both ends of bottom wall 16 in a U shape. The distal end of the second extension portion 28 is formed into the spring contact portion 30 so as to overlap the first extension portion 26, and the side edge portions 36 of the side walls 18 and 20 are provided to surround the spring contact portion 30.
Bend 38 to define the pin contact insertion opening 48.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a socket contact that inserts a pin contact element to connect an electric circuit between electronic devices.

[0002]

[Prior Art]

 In a socket contact manufactured by pressing or forming a thin elastic metal plate with a forming machine, a part of the thin metal plate is formed in the spring part that contacts the pin contact, and in order to protect this contact part from the outside, Conventionally, many socket connectors have been provided which are formed by bending the parts on both sides into a box shape and surrounding the contact part from three sides. As examples thereof, utility model application publication No. 60-110930, utility model application publication No. 2-77876, and U.S. Pat. Nos. 3,836,947 and 4,540,233 can be seen.

By the way, this type of connector is increasingly required to be downsized, but all of the conventional connectors have the disadvantage that the size of the portion surrounding the contact portion becomes large.

[0004]

[Problems to be solved by the device]

 The problem to be solved by this invention is that it is difficult to miniaturize the size of the socket contact of the type in which the spring portion in contact with the pin contact is completely surrounded and protected. ..

[0005]

[Means for Solving the Problems]

 The present invention realizes a socket contact molded from an elastic metal thin plate that completely encloses a portion to be electrically contacted by inserting a pin contact and can reduce the size thereof. did.

[0006]

【Example】

 In the preferred embodiment of the invention, as shown in FIG. 1, the socket contact 10 comprises a box-shaped pin contact receiving portion 12 for receiving the pin contact. The socket contact 10 is formed by punching an elastic thin metal plate as shown in FIG. 2 and bending each part.

The socket contact 10 is bent from the folding lines 12 and 14 so as to stand upright, and the pin contact receiving portion including the bottom wall 16 and the side walls 18 and 20, the core wire crimping portion 22, and the covering caulking portion. And a U-shaped groove forming an electric wire crimping portion composed of 24 and 24. The socket contact 10 further includes a first extension portion 26 and a second extension portion 28 which extend from the bottom wall 16 in the longitudinal direction, respectively. First, the first extension portion 26 is bent inward in a U-shape and then Similarly, the second extension portion 28 is bent inwardly in a U-shape, and its end portion is overlapped above the bent first extension portion 26 and is inserted into the pin contact receiving portion. The spring contact 30 (not shown in the drawing).

Further, in the pin contact receiving portion, the side edges 36 and 38 are bent inward at right angles from the outer folding lines 32 and 34 of the side walls 18 and 20, respectively, as shown in FIG. It is formed in the top wall of the pin contact receiving portion and surrounds the spring contact portion 30.

Next, the outer tabs 40 and 42 of the side walls 18 and 20 are bent inward at right angles from the fold lines 44 and 46, respectively, to form side edges 36 and side edges 36 that form the tops. And 38 form a pin contact insertion port 48 and serve as a pin contact receiving portion cover of the socket contact 10 so that the pin contact can be accurately inserted into the spring contact portion 30.

[0010]

[Effects of the Invention] As will be readily understood from the above-described detailed description, the socket contact of the present invention can be manufactured by pressing an elastic thin metal plate and the bottom wall of the contact. 16 and side walls 18 and 20 standing upright on both sides thereof, and further having first and second extensions 26 and 28 bent inwardly from both ends of the bottom wall 16 to be bent. Further, the tip of the second extended portion 28 is formed on the spring contact portion 30 with the pin contact so as to overlap with the first extension portion 26, and the upright side wall is formed so as to surround the spring contact portion 30. The side edges 36, 38 of the 18, 20 and the tabs 40, 42 at the tips thereof are bent inward at a right angle to limit the insertion port 48 of the pin contact and the spring contact portion 30 inside the socket contact 10. Is protected from the outside.

Therefore, the delicate spring contact portion 30 to be brought into contact with the pin contact of the socket contact 10 is completely surrounded, there is no possibility of being damaged by an external force, and the size of the socket contact 10 is reduced to the conventional one. It has an excellent effect that it can be made extremely small compared to the conventional one.
