The barrel 11 is used to accommodate the central conductor that can be connected with the coaxial cable described below. The extension length, radial dimension and specific shape of the cylinder 11 are set according to requirements. In this embodiment, the barrel 11 is roughly cylindrical. A blocking portion 111 is disposed on the outer peripheral wall of the barrel 11 . The specific shape and structure of the blocking portion 111 is sufficient as long as it can block the shielding member 20 , for example, the blocking portion 111 may be a structure such as a buckle, a boss, or a boss. In this embodiment, the blocking portion 111 includes an inclined guiding surface (not shown in the figure) and a blocking plane (marked in the figure). The inclined guide surface intersects with the outer peripheral wall of the cylinder body 11 and is arranged obliquely, so as to facilitate the installation of the shielding member 20 . The blocking plane is connected to the inclined guiding surface, and the blocking plane is vertically arranged on the outer peripheral wall of the barrel 11, so as to achieve the best blocking effect. The number of the blocking parts 111 is selected according to needs, and may be one, two or more. In order to block the force evenly, when there are multiple blocking portions 111 , the spacing between any two blocking portions 111 in the plurality of blocking portions 111 is equal. In this embodiment, there are four blocking parts 111 .

The shielding fitting portion 15 is disposed at the end of the barrel 11 . In this embodiment, the shielding matching portion 15 is disposed at the front end of the barrel 11 .

In this embodiment, the limiting grooves 16 are set at equal depths. Both ends of the limiting groove 16 are opened (not shown in the figure), so as to facilitate the movement of the mounting claw 25 of the shield 20 described below in the opening direction of the limiting groove 16 . It is conceivable that the two ends of the restriction groove 16 are connected end to end with the two sides respectively.

In order to securely arrange the shielding member 20 on the body 10 to obtain stable electromagnetic shielding performance, the body 10 further includes a pressing table 18 . The abutting platform 18 is arranged on the bottom surface of the limiting groove 16 , and is arranged on the cylindrical body 11 to form a conical surface.

A free end of the mounting claw 25 is bent to form a contact portion 251 . The contact portion 251 is in contact with the abutting platform 18 so as to be in contact with it. All the contact portions 251 may be radial with respect to the central axis of the shield 20 .

In order to prevent the installation claw 25 from being pressed radially along the body 10 (such as the extrusion of the casing 40 described below), it is convenient to further cooperate with the installation structure (such as the recessed portion 48 of the casing 40 described below) to limit the shielding The movement of the shielding member 20 also includes a protrusion 23 .

Then, the shielding member 20 is rotated so that the mounting claw 25 moves into the corresponding limiting slot 163 . According to needs, the shielding member 20 can continue to be moved forward, so that the installation claw 25 moves to abut against the abutting platform 18; it can also be pushed by the casing when installing the following casing (or press down) so that the mounting claw 25 moves to abut against the abutting platform 18 .
