Embodiment 1

[0019] The first embodiment of the connector of the present invention includes a shielding structure provided at the end of the connector, wherein the shielding structure is as figure 1 As shown, the housing 1 and the tail nut 2 connected to the tail of the housing 1 are included. The axes of the housing 1 and the tail nut 2 extend in the front-rear direction. The rear end of the housing 1 is provided with an external thread section 10, and the tail screw The cap 2 is connected to the housing 1 through a screw thread, and the housing 1 and the tail nut 2 are provided with a threading channel extending back and forth for cables to pass through.

[0020] The housing 1 is also provided with a spring coil 7 extending back and forth along its axis. The spring coil 7 is electrically connected to the housing 1. The housing 1 is provided with a front stop structure on the front side of the coil 7 to prevent it from moving forward. The rear side of the ring 7 is provided with a rear pushe...

Embodiment 2

[0025] The second embodiment of the connector of the present invention: the difference from the first embodiment is that the front side of the coil is not provided with a front pusher, and the coil directly contacts the inverted edge of the front end of the housing and realizes the connection with the housing Electrical connection.

Embodiment 3

[0026] The third embodiment of the connector of the present invention: the difference from the first embodiment is that the front stop structure is a radially inwardly protruding stopper provided on the inner peripheral surface of the housing. Set to evenly spaced.

[0027] The fourth embodiment of the connector of the present invention: the difference from the first embodiment is that the force transmission structure is a tubular structure that is integrally provided with the tail nut and extends forward from the inverted edge of the tail nut and extends into the housing , The front end of the tubular structure is matched with the rear pusher.

[0028] The fifth embodiment of the connector of the present invention: the difference from the first embodiment is that the compression ring and the tail nut are integrally arranged.

[0029] The sixth embodiment of the connector of the present invention: the difference from the first embodiment is that there is no front pusher in the housi...

Abstract

The invention provides a shielding structure and a connector employing the same. The shielding structure comprises a shell and a tail cap, wherein the tail cap is connected to the tail part of the shell; threading channels which extend back and forth are formed in the shell and the tail cap; a spring coil of which the axis extends along the front-back direction is arranged in the shell; the spring coil is electrically connected with the shell; the shell is provided with a front stopping structure for preventing the shell from moving forwards at the front side of the spring coil; the rear side of the spring coil is provided with a rear pushing element; the front side of the rear pushing element is provided with a front conical surface, of which the diameter is gradually increased from back to front and which is used for pushing the spring coil when the tail cap moves forwards, so that the spring coil radially shrinks and is in electric contact with a cable shielding layer; and a force transmission structure is arranged between the rear cap and the rear pushing element. The connector provided by the invention is simple in structure, convenient to use and relatively good in antimagnetic shielding effect.

Description

Technical field [0001] The invention relates to a conductive connection device, in particular to a shielding structure and a connector using the shielding structure. Background technique [0002] In order to improve the stability of the electrical signal transmitted by the connector, the tail of the connector is generally provided with a shielding structure for shielding electromagnetic interference. For example, the Chinese invention patent with application publication number CN102509960A and application publication date of 2012.06.20 discloses a shielding structure of a circular electrical connector. This shielding structure includes a tail shell, a tail sleeve, and a tail sleeve. The shielding spring ring is provided with a clamp ring at both ends and an elastic spring sleeve with a concave arc surface in the middle. When in use, the cable passes through the tail casing and the tail casing, and its shielding layer is tightly connected with the shielding coil. The shielding co...
