[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0018] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0019] like Figures 1 to 3 As shown, a waterproof power connector that can be quickly installed according to an embodiment of the present invention includes a female connector 1 and a connector base 2. The female connector 1 includes a positioning member 11 and a plurality of elastic buckles 12 disposed on the positioning member 11 perpendicular to the connection surface of the female connector 1 and the male connector. The positioning member 11 includes a housing and a positive connection unit, a negative connection unit and a plurality of signal terminal connection units disposed in the housing. The positive connection unit includes a positive socket 13 and a negative terminal 14 with a blade-type insert structure disposed in the positive socket 13. The negative connection unit includes a multi-point elastic structure positive contact 15 and a positive connection piece 16 connected to the multi-point elastic structure negative contact. The signal terminal connection unit includes a terminal connection contact with a symmetrical contact design and a signal terminal connection piece 18 disposed at the end of the terminal connection contact. It is evident that the positive terminal connection unit includes a positive terminal socket 13 and a negative terminal 14 with a blade-type insert structure disposed in the positive terminal socket 13. The negative terminal connection unit includes a multi-contact elastic structure positive terminal contact 15 and a positive terminal connecting piece 16 connected to the multi-contact elastic structure negative terminal contact, realizing a male and female terminal structure design, effectively ensuring reliability and safety.

[0020] In addition, the elastic claw structure on the positioning component 11 can be quickly pushed into the battery housing, so that the connector has no additional screw holes or other installation structures, the overall size is extremely small, and the compatibility is stronger. At the same time, based on actual use needs, in addition to the waterproof effect brought by the tight connection of the elastic buckle 12, the waterproof requirements for outdoor use scenarios also need to be considered. Therefore, an additional sealing mechanism needs to be added to the surface of the connection position. In specific implementation, a rectangular flange structure 5 is set on the end of the shell facing away from the connector 2, and a seal is set on the side of the flange structure 5 facing the connector 2 to achieve supplementary waterproofing.

[0021] The specific configuration of this seal is achieved by combining a radial sealing lip ring 3 and an axial end face sealing serrated gasket 4. The lip ring 3 and the serrated gasket 4 are integrally formed, which can fully fill the gap between the female connector 1 and the connecting seat 2 in the assembled state, and achieve excellent sealing and waterproof effect.

[0022] In addition, the narrow end of the flange structure 5 is provided with a square anti-misalignment mounting position 6. The design of the anti-misalignment mounting position 6 can effectively prevent misalignment damage and sealing gaps caused by improper operation during insertion. Specifically, the terminal contact point is set as a tuning fork-shaped terminal contact point 17, which can realize the stable embedding of the signal terminal in the insertion state. At the same time, the end of the negative contact of the multi-point elastic structure is provided with an anti-over-insertion limit block 7, which can effectively prevent excessive insertion in the connection state from causing damage to the connection device.

[0023] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
