Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Reference Figures 1-4 This utility model provides a technical solution: a waterproof high-current female connector, including a connector body 1, with a connector 2 and a connector 4 respectively provided at both ends of the connector body 1. A fastening ring 3 is provided on the outer surface of the connector body 1, and the fastening ring 3 is located close to the connector 2. The outer surface of the fastening ring 3 is provided with anti-slip texture 5. Through the anti-slip texture 5, when the external plug is inserted into the connector 2 by rotating the fastening ring 3, the external plug and the connector 2 are fastened, making the insertion more stable and preventing the problem of falling off. In addition, the anti-slip texture 5 on the outer surface of the fastening ring 3 can effectively prevent the problem of slippage between the palm and the fastening ring 3 when the fastening ring 3 is held and rotated, which facilitates the rotation of the fastening ring 3, that is, facilitates the connection between the connector 2 and the external plug.
[0025] The fastening ring 3 has a first sealing component 6 inside. The first sealing component 6 includes a snap-fit groove 61 and a sealing ring 62. The snap-fit groove 61 is opened inside the fastening ring 3, and the sealing ring 62 is movably snapped into the inside of the snap-fit groove 61.
[0026] A spring 63 is fixedly connected between the inner surface of the snap-fit groove 61 and the sealing ring 62, which is inserted into one side surface inside the snap-fit groove 61. The thickness of the sealing ring 62 corresponds to the opening size of the snap-fit groove 61. A fixing sleeve 64 is provided inside the spring 63. A movable insertion post 65 is movably inserted into the inside of the fixing sleeve 64. One end of the movable insertion post 65 is fixedly connected to one side surface of the sealing ring 62. The fixing sleeve 64 is fixedly installed on the inner surface of the snap-fit groove 61. In actual use, as the fastening ring 3 rotates, it can tighten the seal. As the fastening ring 3 moves toward the external plug, one side of the sealing ring 62 comes into contact with the external plug. During this contact, the sealing ring 62 slowly retracts into the snap-fit groove 61. Under the action of the spring 63, one side of the sealing ring 62 fits tightly against the external plug, achieving a seal between the connector 2 and the external plug. This increases the sealing effect during insertion and prevents humid air from entering the device during prolonged use in a humid environment, ensuring a safe connection.
[0027] Furthermore, by using the fixed sleeve 64 and the movable plug 65, when the sealing ring 62 moves toward the inside of the snap-fit groove 61, the movable plug 65 can simultaneously retract into the fixed sleeve 64. This arrangement can prevent the sealing ring 62 from rotating inside the snap-fit groove 61 after contacting the external plug, thus increasing the stability of the sealing ring 62.
[0028] The second connector (4) includes a sealing sleeve (71) that is connected to an external plug harness and a second sealing component (7) that is detachably fitted on the outside of the sealing sleeve (71).
[0029] Positioning blocks 72 are fixedly installed on both sides of connector 2 4. A positioning frame 74 is provided above connector 2 4. Positioning blocks 75 are fixedly installed on both sides of positioning frame 74. Positioning blocks 75 correspond to the positions of positioning blocks 72. Threaded holes 73 are provided inside both positioning blocks 75 and threaded holes 73. Fastening bolts 76 are threaded into the threads of the threaded holes 73. Through the provided second sealing component 7, another external plug can be fixed in actual use. That is, after the other external plug is inserted into connector 2 4, the positioning frame 74 can be fastened. The outer surface of connector 2 4 is aligned with the threaded hole 73 and the positioning block 2 75. Then, the fastening bolt 76 is inserted into the threaded hole 73 of the positioning block 2 75 and the positioning block 1 72. By rotating the fastening bolt 76, the positioning frame 74 can move downward above connector 2 4 until the inner wall of the positioning frame 74 is in contact with the sealing sleeve 71. Continue to tighten the fastening bolt 76, and the inner wall of the positioning frame 74 can squeeze the sealing sleeve 71, tightly covering the wire harness of the other external plug, thereby achieving the purpose of further preventing moisture from entering.
[0030] Specifically, the working process or working principle of this waterproof high-current female connector is as follows: During use, by holding and rotating the fastening ring 3, the fastening ring 3 can be moved towards the external plug. As the fastening ring 3 moves, one side surface of the sealing ring 62 can contact the external plug. During the contact process, the sealing ring 62 can slowly retract into the inside of the snap-fit groove 61, and under the action of the spring 63, one side surface of the sealing ring 62 can be tightly fitted with the external plug, realizing the seal between connector 1 2 and the external plug. By rotating the fastening bolt 76, the positioning frame 74 can move downward above connector 2 4 until the inner wall of the positioning frame 74 is fitted with the sealing sleeve 71. Continue to tighten the fastening bolt 76, and the inner wall of the positioning frame 74 can squeeze the sealing sleeve 71, tightly covering the wire harness of the other external plug, realizing further sealing.
[0031] It should be noted that both the sealing ring 62 and the sealing sleeve 71 are rubber pads, and both are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
