Further, the protective case is identical as the quantity of contact pin of the male plug part.

Further, a plurality of number of recesses on the insulating sleeve inner sidewall is at least 6.

Further, a plurality of groove surfaces are equipped with electro-insulating rubber.

Further, a plurality of pillar material is electro-insulating rubber.

Beneficial effect

The safety type power connector, the end face periphery that male plug part is connected with mother board are equipped with insulating sleeve, can prevent public affairs Get wet electric leakage when plug-in unit and mother board grafting；The a plurality of groove being arranged in insulating sleeve is equipped with the phase of pillar with mother board periphery Cooperation, can preferably be engaged, and connect stronger；Groove surfaces are equipped with electro-insulating rubber, pillar material is electro-insulating rubber, again Prevent the electric leakage that gets wet；The contact pin of male plug part is surrounded by protective case, and the end face of mother board one end is equipped with protector, works as male and female It is that anticreep effect can be played to single contact pin that plug-in unit, which links together, further improves the safety of the power connection.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of male plug part in the utility model.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings

A kind of safety type power connector, including mother board 1, male plug part 2, the male plug part 2 are connected with the mother board 1 End face periphery be equipped with insulating sleeve 3,3 inner sidewall of insulating sleeve is uniformly provided with a plurality of groove 4, a plurality of groove 4 with The axis of the male plug part 2 is parallel, and 1 periphery of mother board is equipped with concave surface 5, and the concave surface 5 is equipped with pillar 6, works as institute State male plug part 2 and when the mother board 1 is plugged in together, the groove 4 on the insulating sleeve 3 with it is convex on the mother board 1 Column 6 is adapted, and the contact pin 7 of the male plug part 2 is surrounded by protective case 8, the protective case 8 and the contact pin 7 of the male plug part 2 Distance is greater than 10mm, and one end of the protective case 8 is fixedly connected with the end face of the male plug part 2, the axis of the protective case 8 and 7 axis of contact pin of the male plug part 2 coincides；The mother board 1 end face corresponding with the male plug part 2 is equipped with protection Slot, size, shape, the quantity of the protector are corresponding with the protective case 8 on the male plug part 2, the axis of the protector Line is parallel with the axis of the mother board 1, and the protective case 8 is identical as the quantity of contact pin of the male plug part 2, the insulation A plurality of 4 quantity of groove on 3 inner sidewall of casing is at least 6, and a plurality of 4 surface of groove is equipped with electro-insulating rubber, a plurality of 6 material of pillar is electro-insulating rubber.

The power source connector structure is simple, in male plug part 2 and 1 grafting of mother board, first, and insulating sleeve 3, the second, groove 4 Surface is equipped with electro-insulating rubber, 6 material of pillar as electro-insulating rubber, and third, the protector that protective case 8 is adapted therewith can play Good leakproof electro ultrafiltration, a plurality of groove 4 for improving the security performance of the power connection, while being arranged in insulating sleeve 3 with 1 periphery of mother board is equipped with matching for pillar 6, can preferably be engaged, and connects stronger.

The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
