Abstract

PURPOSE:To make replacable a second main body which is frequently connected and disconnected so as to allow a general worker to replace the housing with a new one in a short time by dividing the edge connector main body into two parts i.e., a first main body which is mounted on a member to be attached and a second main body to which a printed wiring board is mounted. CONSTITUTION:The edge connector main body is formed as a laminated struc ture divided into two parts i.e., a first main body 2 which is mounted to a member to be attached and a second main body 3 to which a printed wiring board 1 is mounted, and the second main body 3 is capable of being detachably connected to the first main body 2. For example, the printed wiring board 1 is pulled out and a fixing screw 10 by which the second housing 3 causing nonconformity is fixed is removed and the second housing 3 is pulled out of the first housing 2 and replaced with a new, conforming second housing 3. In this case, the recessed portion 4b of the first housing 2 and the projecting portion 6b of the second housing 3 are detachably fitted with each other where by the second housing 3 can be replaced. Thus even a general worker can replace the housing with a new one in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stacked edge connector and a socket, and particularly to an edge connector to which a printed wiring board is attached and detached, and a socket to which a semiconductor integrated circuit device is attached and detached. The present invention relates to a technique that is effective when applied to a stacked edge connector and socket in which the edge connector and socket main body is divided into two parts, and the main body side to which a printed wiring board and a semiconductor integrated circuit device are attached can be easily replaced.

[Prior Art] For example, when a printed wiring board is mounted in a target electronic device, or in an aging device and quality inspection device for operation tests, characteristic tests, etc., multiple connections of the printed wiring board are required. Edge connectors are generally used in which a plurality of electrode contacts are disposed at positions corresponding to the contacts and are fitted into the connection contacts.

By the way, as an edge connector for such a printed wiring board, for example, "Comprehensive Electronic Components Handbook JP1035-P1" published by Dempa Shimbunsha, May 20, 1980,
As described in documents such as No. 037, there are connectors in which a mounting groove into which a printed wiring board is mounted is formed in the connector body, and a plurality of electrode contacts are arranged on both sides of the mounting groove. Then, the printed wiring board is attached to the edge connector, and each connection contact of the printed wiring board contacts and is held by each electrode contact of the edge connector, so that the printed wiring board is electrically connected through the edge connector.

Similarly, regarding sockets into which semiconductor integrated circuit devices are installed, for example, Dempa Shimbunsha, May 20, 1980.

For example, repeated attachment and detachment of printed wiring boards and semiconductor integrated circuit devices may cause electrical malfunctions due to deterioration or damage to the electrode contacts of edge connectors and sockets, or mechanical damage such as structural damage to edge connectors and socket bodies. A problem has occurred.

In order to deal with such a defect and replace the edge connector and socket with a non-defective one, there is a drawback that a general worker cannot do the replacement because a sophisticated technique is required.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to divide the edge connector body into two parts: a first body to be attached to a member to be attached, and a second body to which a printed wiring board is attached, so that attachment and detachment can be frequently performed. It is an object of the present invention to provide a laminated edge connector in which a second main body is replaceable and can be easily replaced in a short time even by a general worker who has not acquired specific skills.

Another object of the present invention is that the socket main body is divided into two parts, the first main body and the second main body, as described above, and the second main body, which is frequently attached and detached, can be replaced, so that general work can be carried out easily. The object of the present invention is to provide a laminated socket that can be easily replaced even with the skill of an expert.
