Abstract

The utility model relates to a water-proof positioning plug, which is composed of an outer shell (1), an inner seat (2), an inner cover (3), an electric wire (4), and an insert edge (5), wherein, an inner cover for sealing is additionally arranged on the inner seat (2) of the plug, and a section of sandwich part (22), (23) and a reverse-buckling rim (23), (33) extend out at the tail end; the whole body can clamp the electric wire (4) after the whole body is sandwiched in the inner part of the outer shell, and the reverse-buckling rim (23), (33) and the tail end of the outer shell can just buckle and clamp each other. Thus, a fixed and stable plug which is water-proof is obtained.

Description

A kind of waterproof polarized plug

The utility model relates to the electric elements class, particularly a kind of waterproof polarized plug.

As everyone knows, the slotting head or tail that general lamp string is used is inserted structure, water-proof function must be arranged, in order to avoid when outdoor application, because of the infiltration of rainwater causes short circuit, cause and damage or fire, because reaching between interior seat two members, the shell of plug only utilizes simple urgent combination usually in addition, so the steadiness deficiency, when using, can cause getting loose or separating of shell and interior seat, produce adverse consequences.

The purpose of this utility model is exactly the shortcoming that exists at the plug that above-mentioned lamp string is used, and a kind of waterproof polarized plug is provided.

Technical conceive of the present utility model:

According to the purpose of this utility model, a kind of waterproof polarized plug is provided, its structure mainly is an interior inner cap that adds with sealing usefulness at plug, and extend one section sandwich part and back-off edge at tail end, integral body can plug together after enclosure, clamp electric wire, and the back-off edge card that just can interlock with the clamping edge of shell tail end.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is a three-dimensional appearance schematic diagram of the present utility model.

Fig. 2 is the perspective exploded view of shell of the present utility model and interior seat.

Fig. 3 is a perspective exploded view of the present utility model.

Fig. 4 is a cross-sectional schematic of the present utility model.

Fig. 5 is an embodiment perspective exploded view of the present utility model.

(1) be that shell, (11) are that sandwich part lower edge, (23) for down back-off edge, (3) for inner cap, (31) for combined hole, (32) be sandwich part upper limb, (33) for last back-off edge, (34) for brace, (4) for electric wire, (5) for slotting sword, (6) be conducting strip for interior seat, (21) for column, (22) for clamping edge, (2).

As accompanying drawing 1 to shown in the accompanying drawing 4, the utility model is made of shell (1), interior seat (2), inner cap (3), electric wire (4), slotting sword (5), top mat a connecting piece (34) of seat (2) is provided with an inner cap (3) wherein, seat (2) each angle end is established with several columns (21) and inner cap (3) relative position and is established with several combined holes (31) in cooperating, and makes the two be able to easy integrated positioning; The tail end of inner cap (3) is provided with a sandwich part upper limb (32), and interior seat (2) tail end is provided with relative sandwich part lower edge (22), make electric wire (4) be placed in interior seat (2) inside in conjunction with inserting sword (5), and electric wire (4) is protruding by the sandwich part place, and is the closely clamping of inner arc surface institute of upper limb (32) and lower edge (22); Be provided with back-off edge (33) in the outer end of sandwich part upper limb (32), and sandwich part lower edge (22) is provided with down back-off edge (23), when whole when inserting the endoporus of shell (1) together with electric wire (4), two back-off edge (33), (23) just can with the clamping edge (11) that is located at shell (1) tail end buckle mutually, form firm combined effect and make interior seat (2) more tight, will not break away from shell with the associativity of inner cap (3); Under the dual folder bundle of inner cap (3) and clamping edge (11) and back-off edge (23), (33), make sandwich part firmly be clamped electric wire, can prevent that electric wire from being pullled and the situation of separating with slotting sword or conducting strip takes place, and can waterproof.

Be Application Example of the present utility model as shown in Figure 5:

Utilize conducting strip (6) combination electric wire (4) in interior seat (2), can obtain similar waterproof effect and firm associativity.
