It is intended to be attached to the dip-type socket 20. The tip surface of the dip-type socket 10 is exposed from the opening 21 in the attached state.

First, the dip type socket 10 will be described. The tip surface of the socket main body 11 made of a rectangular tubular resin molded product or the like has a plug connecting portion where the plug is connected through the opening 21.
13 and a positioning flange 111 is provided on the outer frame portion of the plug connecting portion 13. The base end side of the socket body 11 is a mold portion 12, and the lower end surface of the mold portion 12 has a connecting pin 12 electrically connected to the plug connecting portion 13.
1 is protruding.

The dip type socket 10 having such a structure is mounted on the substrate 50 by soldering. That is, the connection pin 121 is inserted into the through hole 51 formed in the board 30, and the tip end portion of the connection pin 121 protruding from this is soldered to the land and the like formed on the board 50. 10 is adapted to be attached to the board 50.

However, the dip type socket 10 is
Instead of being screwed to the housing 20 via 50, it is screwed to the housing 20 via a socket holding member 30 described below. In addition to the through hole 51 described above, a positioning hole 52 and an escape hole 53 are provided on the substrate 50, respectively. The escape hole 53 is a socket holding member.
It is assumed that the screw 30 is slightly larger than the head of the screw 53 required to attach it to the housing side.

The socket holding member 30 is a socket holding base formed by bending an iron plate or the like into a box shape as shown in FIG. 2, and a socket insertion hole having a shape corresponding to the outer frame of the socket body 11 is formed on this surface. 31 is provided. The lower end portion of the socket holding member 40 is provided with a positioning piece 32 and a screw insertion hole 33, which will be described in detail later. The height of the socket holding member 30 is set to a length corresponding to the distance between the positioning flange 111 of the dip type socket 10 and the lower end surface of the flange portion 12.
