Description

A kind of shielding spring coil

Technical field

The present invention relates to electromangnetic spectrum field more particularly to a kind of shielding spring coils.

Background technology

Although communicating equipment product volume is smaller and smaller, the electromagnetic interference between the multiple ports of inside communication equipment is asked Topic is increasingly severe, it is therefore desirable to be electromagnetically shielded to being designed on each port of inside communication equipment, be set for realizing communication It is standby from external electromagnetic interference, while but also the electromagnetic wave that port itself generates can not cause other ports to external radiation Interference.

Currently, there are two ways to realizing electromagnetic shielding to communication equipment port：One, using conducting foam or rubber ring sleeve It is connected on port outer wall, and bonding with the screening cover that is set to port outer wall, two, using with multiple inside bending spring teeth Metal ring plate is socketed on port outer wall, and bonding with the screening cover that is set to port outer wall.

But in place of the equal Shortcomings of above two method, disadvantage is that：In first method, electric foam Or the weatherability of rubber ring sleeve, reliability and resilience are all poor, and not reproducible installation uses, once using long, then shields Performance is covered to decline seriously；In the second approach, although metal ring plate overcomes weatherability, reliability using metallic resilient material And the problem that resilience is all poor, but due to there is wide arc gap between multiple spring teeth so that shield effectiveness declines, especially When interval takes positive limit tolerance between metal ring plate and screening cover, shield effectiveness declines apparent.

Specific implementation mode

To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing Step ground detailed description.

As shown in Figure 1 to Figure 3, it is in the embodiment of the present invention, a kind of shielding spring coil of proposition can be sheathed on offering The screening cover 3 of via on port outer wall matches, including inner ring 1 and outer ring 2；Wherein,

Inner ring 1 is including the first top surface 11, the first bottom surface 12 and through the first top surface 11 and the first bottom surface 12 and can be arranged In the first cavity 13 of port outer wall, and the one or more first for being located at 13 outside of the first cavity is equipped on the first top surface 11 Spring tooth 14；

Outer ring 2 is including the second top surface 21, the second bottom surface 22 and through the second top surface 21 and the second bottom surface 22 and can be arranged In the second cavity 23 of port outer wall, and it is equipped on the second top surface 21 and is located at the outside of the second cavity 23 and can be with corresponding the One spring tooth 14 carries out matched one or more second spring teeth 24, mutually solid with screening cover equipped with can be used on the second bottom surface 22 Fixed cohesive material；

When inner ring 1, which is embedded in outer ring 2, to be fixed, by every 1 first spring tooth 14 respectively with corresponding second spring tooth 24 Closed connection is formed after being mutually engaged.

It should be noted that after inner ring 1 and outer ring 2 are fixed, pass through the cohesive material of the second bottom surface 22 of outer ring 2（Such as Conductive gum）It fixes, can avoid at port in temperature changing process, shielding spring coil position occurs with screening cover 3 with 3 phase of screening cover It moves, to reduce shield effectiveness；Simultaneously as the first spring tooth 14 of inner ring 1 carries out being engaged formation with the second spring tooth 24 of outer ring The effect of closed barrier shield is played in closed connection, itself and screening cover 3 are socketed on after port outer wall for making up shielding spring coil Between there are the harmful effects such as build-up tolerance, therefore can go out to avoid the electromagnetic radiation generated at port, it is preferable to reach Shield effectiveness.

In one embodiment, it shields the inner ring 1 of spring coil and outer ring 2 is all made of metallic resilient material and is made, commonly use Metallic resilient material have beryllium copper, and be integrally formed by metal plate punching technique, wait for that inner ring 1 passes through to be welded with outer ring 2 and fix After forming shielding spring coil together so that the shielding spring coil is simple in structure, and has preferable weatherability.

In order to realize the effect of good earth, further avoid at port in temperature changing process, shielding spring coil and shielding There is offset phenomena between lid 3, to reduce shield effectiveness the phenomenon that occurs, therefore inner ring 1 is equipped with along the first cavity 13 Inside wall edge extends and protrudes from the first bottom surface 12 and can be with default portion in 3 via of screening cover（It is not shown）Mutually multiple the of occlusion One fixation grabs 15.

It is further to avoid offset phenomena occur between shielding spring coil and screening cover 3, it is additionally provided on inner ring 1 along the first sky The inside wall edge of chamber 13 extends and protrudes from multiple first flaps 16 of the first bottom surface 12, each first flaps 16 can be with screen The inner wall for covering 3 via of lid leans, to effectively prevent offset phenomena occur.

Further to avoid occurring offset phenomena between shielding spring coil and screening cover 3, outer ring 2 extends along its outer wall edge Go out 22 certain length of the second bottom surface and portion can be preset with shielding cover outer wall（It is not shown）Mutually multiple the second of occlusion, which are fixed, grabs 25.

Further to avoid offset phenomena occur between shielding spring coil and screening cover 3, outer ring 2 is also prolonged along its outer wall edge Multiple second flaps 26 of 22 certain length of the second bottom surface are stretched out, each second flaps 26 can be with the outer wall phase of screening cover 3 Against to effectively prevent offset phenomena occur.

Implement the embodiment of the present invention, has the advantages that：

In embodiments of the present invention, due to shielding spring coil by can be socketed on port outer wall inner ring and outer ring assemble and At, be mutually engaged with the second spring tooth of outer ring by the first spring tooth of inner ring, realize shielding spring coil on all spring teeth formed Closed connection, while underrun cohesive material securely fixes together with screening cover so that the shielding spring coil has structure Simply, good weatherability and high reliability can prevent port electromagnetism from being radiate by the spring tooth of closed connection, and energy It prevents in temperature changing process, shielding spring coil displacement occurs and reduce shield effectiveness with screening cover, good to reach shield effectiveness Purpose.

It is above disclosed to be only a preferred embodiment of the present invention, the power of the present invention cannot be limited with this certainly Sharp range, therefore equivalent changes made in accordance with the claims of the present invention, are still within the scope of the present invention.
