In shape groove 306, and the chuck being engaged with the side wall of round boss 302 is formed between platform 403 and rectangular preiection 405；Arc is consolidated
Between the top of fixed board 4 and arc convex 407 for extend out from bottom to top domatic 408 so that the conductive head 701 of subheader can be
This slides on domatic 408 and snapped onto after overcoming the elastic force of ring spring 5 in arc-shaped recess 304；
For another example, restriction arc is respectively arranged with around the upper and lower part of some lateral walls of arc fixed plate 4 to fix
The spacing ring 6 of the maximum extent of plate 4；
For another example, the limit card slot 702 of annular is provided with the conducting rod 7 of the subheader, the limit card slot 702 is consolidated with arc
The arc convex 407 that the upper inner wall of fixed board 4 is provided with is engaged, and conductive head 701 is locked in cavity 401；
Again for another example, the female connecting hole 703 of tool is provided with one end in the insertion of the conducting rod 7 insulation leather sheath 9,
The connecting hole 703 is threadedly coupled with the connector 801 of the end of cable core 8；
Finally, in order to solve the problems, such as whole joint sealing waterproof, following structure can be used：
First, the material selection silica gel material of elastic rubber sleeve 2, its height is concordant with arc fixed plate 4, and top also has
There is the shielding part 203 of phase same material（That is, integral shielding part 203 is provided with the top of elastic rubber sleeve 2）, covering
A patchhole 202 passed through for subheader is opened in portion 203, and patchhole 202 is interference fitted with subheader；
Then, cover plate is set on the top of insulating sleeve 1, shielding part 203 and elastic rubber sleeve 2 are entirely sealed in by cover plate
Wherein, there is the hole with the position of patchhole 202 and size all same on cover plate；
Meanwhile the conducting rod 7 of subheader makes following structure, inside is a conductive core 705 being connected with conductive head 701,
The outer wrap insulator 704 of conductive core 705, the other end of conductive core 705 are contacted with cable core 8, and ring is provided with insulator 704
The limit card slot 702 of shape, the arc convex 407 that the limit card slot 702 is provided with the upper inner wall of arc fixed plate 4 match
Close；Moreover, be inserted into subheader in cavity 401, when conductive head 701 is with 304 clamping of arc-shaped recess, the end energy for the leather sheath 9 that insulate
Enough it extend into patchhole 202；
After said structure, after the conducting rod 7 of subheader is inserted into cavity 401 by patchhole 202, due to subheader
It is interference fit with cavity 401, so extending out arc fixed plate 4 and then extruding elastic rubber sleeve 2, because elastic rubber sleeve 2 is silicon
Glue material matter, therefore, elastic rubber sleeve 2 deforms, and then patchhole 202 is diminished, so as to improve sealing performance.
