Here, the ring bodies of shielding spring is the ring bodies of opening, is provided with and leads on tubular power line pluging handhole hole wall
To muscle, the elastic slice for the shielding spring being compressed on shading ring opens the ring bodies of shielding spring, and guiding rib then suppresses shielding
The ring bodies of spring opens, so that shielding spring be made closely to connect with shading ring and tubular power line pluging handhole.
It inserts in the hole in tubular power line and is provided with flange, to prevent shielding spring from moving in terminal box.
Seal rubber inner sidewall and lateral wall have multiple annular recess, to promote the effect of its sealed motive force line.
Beneficial effect
1. the processing and manufacturing of terminal box is simple, the tubular power line pluging handhole for installing power line does not need to be finished, favorably
In raising yield rate manufacture efficiency.
2. using the seal rubber coil structures of multiple groove, sealing effect is more preferable.
3. the click-on design in terminal box does not need to install fixed tail-hood with bolt, easy to operate, in vehicle operational process
In can prevent tail-hood from falling off.
4. the shielded layer of power line is directly compressed with shading ring, shielded cable and shield terminal and bolt are saved, and
And it can achieve 360 ° of shield effectiveness.
