The utility model provides a technical problem adopt following technical scheme to realize: the utility model provides a fast-plug waterproof electric connector for high-speed train, which comprises a rubber sleeve A, a rubber sleeve B, a plug terminal A and a plug terminal B, wherein the rubber sleeve A and the rubber sleeve B are respectively sleeved outside two connected electric wires, the plug terminal A and the plug terminal B are respectively pressed on the wire cores of the two connected electric wires, and the plug terminal A and the plug terminal B are matched through plug connection to realize the electric connection between the two electric wires;
the rubber sleeve A is provided with a connecting bulge on the inner side of one end facing the rubber sleeve B, the rubber sleeve B is provided with a connecting groove matched with the connecting bulge, and after the rubber sleeve A and the rubber sleeve B are spliced, the connecting bulge is matched with the connecting groove, so that the rubber sleeve A and the rubber sleeve B are connected together;
the inside of the terminal surface of the rubber sleeve A towards the rubber sleeve B is provided with an inward protruding positioning protrusion, the wiring terminal B is pressed on a wire core of the wire, and the positioning protrusion is clamped between the wiring terminal B and an insulating sheath of the wire, so that the rubber sleeve B is connected to the wire, and the axial displacement of the rubber sleeve B is prevented.
The end part of the rubber sleeve B facing the rubber sleeve A is also provided with a hoop part which is bound on the outer side of the rubber sleeve A.
The utility model has the advantages that: the utility model discloses mainly adopt the rubber material to make, the processing cost and material cost are very low, simple structure, and waterproof reliability is good. And simultaneously, the utility model discloses have less diameter, very big convenient wiring.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the cable comprises a wire 1, a wire core 2, a plug terminal A3, a plug terminal B4, a rubber sleeve A5, a connecting bulge 6, a rubber sleeve B7, a hoop part 8 and a positioning bulge 9.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
the embodiment comprises a rubber sleeve A5, a rubber sleeve B7, a plug terminal A3 and a plug terminal B4, wherein the rubber sleeve A5 and the rubber sleeve B7 are respectively sleeved on the outer sides of two connected electric wires 1, the plug terminal A3 and the plug terminal B4 are respectively pressed on wire cores 2 of the two connected electric wires 1, and the plug terminal A3 and the plug terminal B4 are in plug fit to realize the electric connection between the two electric wires 1. In the structure, the rubber sleeve A5 and the rubber sleeve 7 are respectively hooped on the outer side of the electric wire 1 through self elasticity, so that no gap exists between the electric wire 1 and the rubber sleeve A5, and the waterproof requirement is met. The plug terminal A3 and the plug terminal B4 are connected to the wire core 2 by a crimping process, which is the most common method of connecting terminals to the wire core 2 in the prior art, and the principle is that the plug terminal A3 and the plug terminal B4 are plastically deformed by applying pressure to be clamped at the end of the wire core 2.
The rubber sleeve A5 is provided with a connecting bulge 6 towards the inner side of one end of the rubber sleeve B7, the rubber sleeve B7 is provided with a connecting groove matched with the connecting bulge 6, and after the rubber sleeve A5 and the rubber sleeve B7 are spliced, the connecting bulge 6 is matched with the connecting groove, so that the rubber sleeve A5 and the rubber sleeve B7 are connected together. The connecting protrusion 6 can effectively improve the connecting strength between the rubber sleeve A5 and the rubber sleeve B7, thereby ensuring the waterproof performance of the joint between the rubber sleeve A5 and the rubber sleeve B7.
The rubber sleeve B7 is provided with a positioning bulge 9 protruding inwards towards the inner side of the end face of the rubber sleeve A5, after the wiring terminal B4 is pressed on the wire core 2 of the electric wire 1, the positioning bulge 9 is clamped between the wiring terminal B4 and the insulating sheath of the electric wire 1, and therefore the rubber sleeve B7 is connected on the electric wire 1 and is prevented from axial displacement.
The rubber sleeve B7 is also provided with a hoop part 8 at the end part facing the rubber sleeve A5, and the hoop part 8 is bound on the outer side of the rubber sleeve A5. The hoop ring part 8 is a thin-wall structure, and the wall thickness is not more than 2 mm. Before the rubber sleeve A5 and the rubber sleeve B7 are inserted, the hoop part 8 can be turned outwards (the hoop part 8 is easier to turn outwards because the rubber has elasticity and the wall thickness of the hoop part 8 is smaller), and after the protrusion 6 to be connected enters the matching position shown in figure 1, the hoop part 8 is clamped outside the end part of the rubber sleeve A5 again (namely, the position shown in figure 1). The provision of the hoop portion 8 effectively prevents the rubber bush a5 from expanding radially at the coupling projection 6, thereby further preventing the rubber bush a5 and the rubber bush B7 from being disengaged.
The utility model discloses mainly adopt the rubber material to make, the processing cost and material cost are very low, simple structure, and waterproof reliability is good. And simultaneously, the utility model discloses have less diameter, very big convenient wiring.
