Drawings
Fig. 1 is a cross-sectional view of the spring type electromagnetic shielding connector provided in this embodiment.
Detailed Description
The spring type electromagnetic shielding connector of the present invention is further described with reference to fig. 1.
A spring electromagnetic shielding joint is characterized in that: comprising a housing 1, a sealing ring 2 and an elastic shielding ring 3. The casing 1 comprises a tubular body 12 and a connecting cap 11, which are connected to each other and are made of POM or PPS material. The sealing ring 2 is fixed in the connecting cap 11. The elastic shielding ring 3 is fixed in the tubular body 12.
As a preferred way of connecting the connecting cap to the tubular body, the connecting cap 11 is connected with the tubular body 12 by screw-fitting. That is, an internal thread is provided on the inner side wall of the connecting cap 11, and an external thread to be fitted to the internal thread is provided on the outer side wall of the tubular body 12.
As a preferred embodiment of the sealing ring in the connecting cap, an end of the connecting cap 11 facing away from the tubular body 12 is provided with an inward flange 111 against which the second end of the sealing ring 2 abuts, and the first end of the sealing ring 2 abuts against the end wall of the tubular body 12. In a connection state of the connecting cap 11 and the tubular main body 12, one end of the tubular main body 12, which faces the connecting cap 11, is located in the connecting cap 11 and protrudes out of the inner wall of the connecting cap 11, so that the first end of the sealing ring 2 abuts against and is supported by the first end; the second end of the sealing ring 2 is supported on the inner flange 111. After tightening the connection cap 11, the sealing ring 2 can be pressed between the turned-in edge 111 and the end wall of the tubular body 12, achieving the positioning of the sealing ring 2.
In order to improve the clamping effect of the sealing ring on the cable, the outer side wall of the sealing ring 2 is provided with a ring groove 21. When the sealing ring 2 is extruded by the inner flanging 111 and the end wall of the tubular main body 12, the ring groove 21 structure on the outer side wall of the sealing ring 2 makes the sealing ring 2 stressed unevenly, and the position of the sealing ring 2 corresponding to the ring groove 21 deforms to the center position of the sealing ring 2, so that the clamping effect on the cable passing through the sealing ring 2 is achieved.
As a preferable mounting structure of the elastic shielding ring in the tubular body, the tubular body 12 has an annular mounting groove 121 on an inner wall thereof, the elastic shielding ring 3 is disposed in the annular mounting groove 121, and the elastic shielding ring 3 and the tubular body 12 are of a concentric structure.
As a preferable fitting structure of the elastic shield ring and the annular mounting groove, the section of the annular mounting groove 121 is a dovetail structure, the section of the elastic shield ring 3 is a triangular structure, and the apex 31 of the triangle extends toward the center of the elastic shield ring 3. Under this structure can make the stable block of elasticity shield ring in mounting groove 121, the elasticity shield ring apex angle 31 towards elasticity shield ring 3 center can be with the cable steady contact simultaneously, plays electromagnetic shield effect.
In the specific use process, compared with the housing 1 composed of the metal connecting cap 11 and the metal tubular body 12 in the prior art, the tubular body 12 and the connecting cap 11 made of POM or PPS material can significantly reduce the overall weight of the cable joint, and can also reduce the cost of the cable joint. When the shell 1 is required to have a conductive function, the connecting cap 11 and the tubular main body 12 are made of POM materials.
