Providing socket contacts. [Structure] A plurality of socket contact bodies 1 are formed, and guide groove portions 4 for accommodating a part of the pin contacts are formed on the pin contact sandwiching surfaces of these socket contact bodies 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a socket connector used for a narrow pitch connector.

[0002]

[Prior Art]

 In recent years, as electronic devices have become smaller, connectors are also required to have smaller sizes and narrower pitches.

Conventionally, a socket contact 100 as shown in FIG. 7 is known as a contact used for a narrow pitch connector. This socket contact 100 is formed by arranging a plurality of socket contact members 101 having a single layer structure as shown in FIG. 6 in parallel as shown in FIG.

Since the insulating partition wall cannot be formed by the molding technique, in order to insulate the adjacent socket contact bodies 101, as shown in FIG. 7, both side surfaces of the socket contact body 101 made of a conductive metal are used. This is done only by arranging the insulating material 102 on the surface where the socket contact bodies 101 face each other. Then, as shown in FIG. 8, the pin contact 103 was fitted while being held by the holding portion of the socket contact body 101.

[0005]

[Problems to be solved by the device]

 However, when there is a slight dimensional deviation in the arrangement of the pin contacts 103, as shown in FIG. 8, the pin contacts 103 and the socket contact bodies 101 do not fit properly and the pin contacts 103 are adjacent to each other. There were many cases where the pin contact 103 was brought into contact with the pin contact 103 to cause a short circuit.

An object of the present invention is to prevent a pin contact from being brought into contact with an adjacent pin contact by a socket contact body even in a narrow-pitch connector having no insulating partition so that adjacent pin contacts come into contact with each other. The purpose is to provide socket contacts.

[0007]

[Means for Solving the Problems]

 According to the present invention, there is provided a socket contact comprising a plurality of socket contact bodies, and a guide groove portion for accommodating a part of the pin contact is formed on a pin contact holding surface of these socket contact bodies.

Further, according to the present invention, in the socket contact, each of the socket contact bodies includes a base body and outer layer bodies formed on both side surfaces of the base body with a material different from that of the base body. A socket contact is obtained in which at least a part of the periphery of the outer layer body is configured to project from the base portion.

[0009]

【Example】

 FIG. 1 shows materials for manufacturing the socket contact of the present invention. The base body 2 of the socket contact body 1 is made of a Cu-based alloy material, and both side surfaces (upper and lower surfaces in the figure) of the base body 2 are outer layers made of a stainless steel-based material having excellent corrosion resistance. The part 3 has a rectangular shape integrally attached thereto. The material is not limited to a rectangular shape, because a press punching process is performed later. Next, the rectangular material is pressed to form a blank as shown in FIG. A portion corresponding to the fitting portion of the blank thus obtained is subjected to etching as shown in FIG. 3 to obtain a guide groove portion 4 having a concave section in the plate thickness direction. Since the base portion 2 is made of Cu alloy and both outer layer portions 3 are made of stainless alloy, they have different workability to etching. The present invention is obtained by utilizing such a difference in workability between both materials.

Although the base portion 2 and the outer layer portion 3 are made of different materials in the above embodiment, the present invention is not limited to this. That is, as shown in FIG. 1, both the base portion 2 and the outer layer portion 3 are made of a Cu-based alloy, the base portion 2 is made of a soft material, and the outer layer portion 3 is made of a hard material. A blank is obtained by punching as in FIG. The blank thus obtained is subjected to abrasive grain processing such as buffing or sandblasting to remove a small portion of the surface of the soft base portion (similar to FIG. 3) to form a concave guide groove portion 4.

The plurality of socket contact bodies 1 thus obtained are arranged in parallel as shown in FIG. 4, and the insulating material 5 is arranged on both side surfaces of the socket contact body 1. Such an insulating material 5 is usually placed on the surface at the material stage, and is usually punched simultaneously with the base metal by the press punching process. It should be noted that such an insulating partition wall 5 does not necessarily have to be provided in a narrow pitch connector.

FIG. 5 shows a state in which the socket contact body 1 holds the pin contact 6 therebetween. The pin contact 6 is held and housed in a concave guide groove portion 4 formed on the holding surface of the socket contact body 1.

[0013]

[Effect of the device]

 According to the present invention, even in a narrow-pitch connector in which an insulating partition wall cannot be provided between the socket contact bodies, the pin connector is guided by the guide groove formed on the pin holding surface of the socket contact body. In addition, since it is properly accommodated and held in the fitted state, it is possible to prevent the pin contact from coming into contact with the adjacent pin contact even when the pin contact is bent or not aligned.
