The male contacts make contact and the connection between the connector socket and the plug is reached.

[0003]

In the conventional small-sized multi-pole connector socket, the circumference of the annular groove 2 is further covered with the insulating body 1. Therefore, the outer peripheral portion of the insulating body existing above and below the annular groove 2 is particularly important. 5 and 6 have a disadvantage that the height H cannot be reduced. Further, when the projecting piece 8 having the mounting hole 7 is provided so as to project on the upper surface, there is a disadvantage that the height H becomes higher.

That is, as a recent tendency, miniaturization, particularly thinness, is required for a device such as a notebook personal computer, an electronic notebook or a portable word processor. Therefore, a short connector socket is also required for the connector socket. It is an object of the present invention to provide a connector socket which is short and yet almost completely shielded.

[0005]

According to the present invention, an insulating body is composed of a columnar body and a flange formed so as to project toward the rear end side of the columnar body, and a shield cover is brought into contact with the outer periphery of the flange. The structure is such that the insulating body is covered with a shield cover by bending.

Therefore, according to the connector socket of the present invention, the height H of the connector socket can be reduced because the shield covers are directly present on the upper and lower sides of the columnar body. The shield cover has a shape in which the columnar portion is covered with a circle, or the columnar portion is U-shaped.
The structure can be covered with a shield cover bent in a letter shape.

In the case where the insulating body is covered with the U-shaped shield cover, the U-shaped open end can be used as the mounting surface on the printed circuit board.
By using the U-shaped open end as the mounting surface to the printed circuit board in this manner, compared to the case where the columnar portion is circularly covered with the shield cover, the shield cover is attached to the printed circuit board at the mounting surface. The height can be reduced by the thickness of the plate.
