Preferably, described fastening seat afterbody inwall is provided with annular flange flange, and described rubber sealing boot outer wall is provided with the annular groove coordinated with described flange seal.
Preferably, described rubber sealing boot comprises I and II that axially sets gradually, and described I is stretched in fastening seat afterbody, and described II is positioned at fastening nut; The contact-making surface of described fastening nut inwall and described II outer wall is wedge surface.Like this, when tightening fastening nut, be sealed and matched by wedge surface, and compress rubber sealing boot and rubber seal plug further, meanwhile, also mouth compression through wires hole, seals individual cord and through wires hole further.
Preferably, described II inwall near one end of clamp nut end face is provided with boss, and described boss is connected to the outer wall of described rubber seal plug.
Preferred further, described II is provided with multiple open slot vertically from one end end face near clamp nut end face, and multiple described open slot hoop interval is arranged, and the inner and outer wall of described II is communicated with by described open slot.Like this, II of rubber sealing boot existing certain activity when extruding, being beneficial to the sealing of individual cord.
Preferably, the external diameter that described II external diameter is greater than described I, and one end of described II is connected on the end face of described fastening seat afterbody.
Further preferred, described II is annular serrated contact face with the contact-making surface of the end face of described fastening seat afterbody.
The beneficial effects of the utility model are: when the moment of fastening nut reaches certain moment, due to stressed extruding between rubber sealing boot and fastening nut, between rubber sealing boot and rubber seal plug, between through wires hole and individual cord, its seal clearance is more and more less, finally reach IP67 waterproof requirement, thus realize the positiver sealing of high-tension connector afterbody, effectively prevent under the low air pressure condition of high-altitude, cause creepage intensity to decline due to poorly sealed, cause that product is withstand voltage to be punctured.
Accompanying drawing explanation
Fig. 1 is exploded perspective view of the present utility model
Fig. 2 is cross-sectional schematic of the present utility model
In figure: the serrated contact face 6 of fastening seat 1, fastening nut 2, rubber sealing boot 3, rubber seal plug 4, wedge surface 5, annular;
Wherein: flange 11, step 31, annular groove 32, I 33, II 34, boss 35, open slot 36, through wires hole 41.
Embodiment
As depicted in figs. 1 and 2, the automobile high-tension connector of the utility model design is to multicore cable waterproof construction, and comprise hollow metal fastening seat 1, described fastening seat 1 afterbody is threaded with the fastening nut 2 of both ends open; Be provided with rubber sealing boot 3 between described fastening seat 1 and fastening nut 2, described rubber sealing boot 3 one end is positioned at described fastening seat 1, and the other end is positioned at fastening nut 2; Also be arranged with rubber seal plug 4 in described rubber sealing boot 3, described rubber seal plug 4 is provided with multiple through wires hole 41 passed for multicore cable individual cord along its axis; Described rubber seal plug 4 one end be connected to be located at described rubber sealing boot 3 inwall step 31 on, the other end is connected on described fastening nut 2.Preferably, described fastening seat 1 afterbody inwall is provided with annular flange flange 11, and described rubber sealing boot 3 outer wall is provided with the annular groove 32 be sealed and matched with described flange 11.
Again as depicted in figs. 1 and 2, preferably, described rubber sealing boot 3 comprises I 33 and II 34 that axially sets gradually, and described I 33 is stretched in fastening seat 1 afterbody, and described II 34 is positioned at fastening nut 2; The contact-making surface of described fastening nut 2 inwall and described II 34 outer wall is wedge surface 5.Like this, when tightening fastening nut 2, be sealed and matched by wedge surface 5, and compress rubber sealing boot 3 and rubber seal plug 4 further, meanwhile, also mouth compression through wires hole 41, seals individual cord and through wires hole 41 further.
