Fixed plate 4, wherein, the bottom of conductive deck 3 is provided with the wire 303 for drawing insulating sleeve 1, the outward flange of conductive deck 3 and
Center is respectively arranged with ring baffle 305 and round boss 302, and the equal activity in bottom of some arc fixed plates 4 is set
Put in the annular groove 306 formed between ring baffle 305 and round boss 302, so that every piece of arc fixed plate 4 can be in ring
Along the radially movable of annular groove 306 in shape groove 306；Upper and lower part around all outsides of arc fixed plate 4 is provided with ring
Shape spring 5, so as to surround the cavity 401 inserted for subheader between all arc fixed plates 4, cavity 401 is matched somebody with somebody with subheader for interference
Close, i.e., after subheader is inserted into cavity 401, arc fixed plate 4 is overcome clamping subheader after the elastic force of ring spring 5；In arc
Elastic rubber sleeve 2 is provided between fixed plate 4 and the side wall of insulating sleeve 1, the round boss 302 is stretched into cavity 401, and its end
Portion is provided with the arc-shaped recess 304 for blocking subheader end；The subheader includes an insulation leather sheath 9 and one end insertion insulation leather sheath 9
Interior conducting rod 7, one end that conducting rod 7 is located in insulation leather sheath 9 is connected with cable core 8, and the other end, which has, extend into cavity 401
And the conductive head 701 contacted with arc-shaped recess 304.
Above for the present invention basic embodiment, can more than on the basis of further improved, optimized and limited：
Such as, described surround has gap, the number of arc fixed plate 4 between the arc fixed plate 4 of cavity 401 and round boss 302
Amount is at least 4-12, and the height that round boss 302 extend into cavity 401 is the 1/4-1/2 of the whole height of cavity 401；
And for example, the connected unit 301 that the conductive deck 3 is set by its bottom is threadedly coupled with the bottom wall of insulating sleeve 1；
And for example, the side wall of the ring baffle 305 towards arc fixed plate 4 is inclined domatic, and this is domatic from bottom up
Towards the sidewall slope of insulating sleeve 1, so that arc fixed plate 4 can have certain outer after subheader is inserted into cavity 401
Expand surplus；
And for example, the ring spring 5 has 4, and every two are one group, and two groups of ring springs 5 are circumferentially positioned at arc and consolidated respectively
The upper and lower part in the outside of fixed board 4；
For another example, the bottom outside of the elastic rubber sleeve 2 is provided with the extension between insertion ring baffle 305 and the side wall of insulating sleeve 1
Portion 201, and extension 201 forms the chuck structure being stuck on ring baffle 305 with the junction of elastic rubber sleeve 2；
For another example, the upper and lower part of the lateral wall of arc fixed plate 4 is respectively arranged with the deep-slotted chip breaker 402 of positioning ring spring 5,
The upper and lower part of the madial wall of arc fixed plate 4 is respectively arranged with arc convex 407 and rectangular preiection 405, and arc convex 407
Depressed part 406 is formed between rectangular preiection 405；The bottom of arc fixed plate 4 is movably arranged on annular groove by platform 403
In 306, and the chuck being engaged with the side wall of round boss 302 is formed between platform 403 and rectangular preiection 405；Arc fixed plate 4
Top and arc convex 407 between for extend out from bottom to top domatic 408 so that the conductive head 701 of subheader can be on the slope
Slide and snapped onto after overcoming the elastic force of ring spring 5 in arc-shaped recess 304 on face 408；
For another example, it is respectively arranged with restriction arc fixed plate 4 most around the upper and lower part of some lateral walls of arc fixed plate 4
The spacing ring 6 of big spreading range；
For another example, the spacing neck 702 of annular, the spacing neck 702 and arc fixed plate are provided with the conducting rod 7 of the subheader
The arc convex 407 that 4 upper inner walls are provided with is engaged, and conductive head 701 is locked in cavity 401；
Again for another example, the female connecting hole 703 of tool, the company are provided with one end in the insertion of the conducting rod 7 insulation leather sheath 9
The connector 801 that hole 703 is connect with the end of cable core 8 is threadedly coupled；
Finally, in order to solve whole joint sealing waterproof the problem of, 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 phase
The shielding part 203 of same material（That is, being provided with integral shielding part 203 on the top of elastic rubber sleeve 2）, in shielding part
A patchhole 202 passed through for subheader is opened on 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 it by cover plate
In, 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, and inside is a conductive core 705 being connected with conductive head 701, conductive
The outer wrap insulator 704 of core 705, the other end of conductive core 705 is contacted with cable core 8, and annular is provided with insulator 704
Spacing neck 702, the arc convex 407 that the spacing neck 702 is provided with the upper inner wall of arc fixed plate 4 is engaged；And
And, it is inserted into subheader in cavity 401, when conductive head 701 is with 304 clamping of arc-shaped recess, the end of insulation leather sheath 9 can extend into
Into patchhole 202；
After said structure, after the conducting rod 7 of subheader is inserted into by patchhole 202 in cavity 401, due to subheader and sky
Chamber 401 is interference fit, so extending out arc fixed plate 4 and then extruding elastic rubber sleeve 2, because elastic rubber sleeve 2 is silica gel material
Matter, therefore, elastic rubber sleeve 2 is deformed, and then patchhole 202 is diminished, so as to improve sealing performance.
