Specific embodiment
The utility model provides a kind of closed type electrocution-proof protection structure at connector mating end.Below in conjunction with attached drawing to this
Utility model technical solution is described in detail, so that it is more readily understood and grasps.
A kind of closed type electrocution-proof protection structure at connector mating end, as shown in Figure 1 to Figure 3, including connector shell
1, it is socketed end cap 2 and sealing ring 3, is socketed the structure annular in shape of capping 4 of end cap 2.
Wherein, connector shell 1 is equipped with mating port 5, and mating port 5 is equipped with elongated end 6, elongated end 6 and mating end
Land 7 is formed between the outer wall of mouth 5, socket end cap 2 is socketed on elongated end 6, and the limit of sealing ring 3 in land 7 and is socketed
Between the lid mouth of end cap 2, port and 4 inner wall of capping of elongated end 6 are abutted against.
It specifically describes, firstly, socket end cap 2 that have the capping 4 of cyclic structure are designed as a protection against electric shock,
It can play the role of electrocution-proof protection, by being socketed the design of end cap 2 and elongated end 6, and be easy to the axial of sealing ring 3 and fix,
It is recessed without being equipped with ring on mating 5 outer wall of port.
Refinement description is carried out to sealing ring 3, if the outer wall of sealing ring 3 is equipped with the sealing ring rib of arterial highway axially spaced-apart setting
