Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a highly compatible waterproof connector. Background Technology
[0002] Connectors, also known as plugs or sockets, are generally electrical connectors, which are devices that connect two active devices to transmit current or signals.
[0003] The existing 2PIN and 3PIN connectors have different overall structural distributions, so different molds are required during production. However, the mold opening cost is high, which greatly increases the production cost of various models of products, thereby reducing the production efficiency of enterprises. Utility Model Content
[0004] The purpose of this invention is to provide a highly compatible waterproof connector to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly compatible waterproof connector, comprising a female terminal upper shell and a first female terminal bullet piece, wherein a mounting plate is fixed to the outer side of the female terminal upper shell, and a waterproof gasket is provided on one side of the mounting plate, and a waterproof cover is connected to the bottom of the waterproof gasket; a connection hole is provided at the top of one end of the female terminal upper shell; the first female terminal bullet piece is disposed at the top of one end of the female terminal upper shell, and a second female terminal bullet piece is disposed at the top of one end of the female terminal upper shell; a third female terminal bullet piece passes through the middle of the female terminal upper shell, and hooks are rotatably connected to both sides of the female terminal upper shell.
[0006] Furthermore, the upper part of the third mother-end bullet piece is F-shaped, and one end of the third mother-end bullet piece is pointed.
[0007] Furthermore, the male terminal lower shell is slidably connected to the other end of the female terminal upper shell, and the male terminal lower shell is fixed with locking blocks on both sides.
[0008] Furthermore, one end of the locking block is arc-shaped, and the upper shell of the female terminal engages with the lower shell of the male terminal through the locking hook and the locking block.
[0009] Furthermore, a male terminal upper shell is disposed inside the lower shell of the male terminal, and a nut fitting is snapped into the upper shell of the male terminal, wherein a hardware nut is disposed inside the nut fitting.
[0010] Furthermore, the hardware nut is rectangular, and the hardware nut matches the groove on the nut fitting.
[0011] Furthermore, a male bullet piece is installed inside the hardware nut by screws, and the male bullet piece is fitted into the male terminal shell.
[0012] Furthermore, a silicone ring is fitted on the outer side of the lower shell of the male terminal, and the silicone ring abuts against the upper shell of the female terminal.
[0013] This utility model provides a highly compatible waterproof connector with the following advantages: This invention, through the arrangement of a first female end bullet piece, a second female end bullet piece, and a third female end bullet piece, allows for the installation of these three pieces inside the upper shell of the female terminal when producing a 3-pin connector, using screws and nuts. When producing a 2-pin connector, only two first female end bullet pieces need to be installed inside the two ends of the upper shell of the female terminal, making the connector compatible with both 3-pin and 2-pin connectors. Therefore, no additional molds are required during production, achieving cost reduction and efficiency improvement. This utility model, through the setting of hooks and blocks, can quickly lock and fix the upper shell of the female terminal and the lower shell of the male terminal after they are inserted, preventing slippage. At the same time, this product is a matching product, and its structure in multiple positions is simplified, reducing operation steps and making installation and maintenance easier. 3. The silicone ring of this utility model can seal between the upper shell of the female terminal and the lower shell of the male terminal, and the waterproof gasket will seal between the mounting plate and the equipment, thereby ensuring the waterproof performance of the connector. When not in use, the waterproof cover can be used to cover the opening of the upper shell of the female terminal, so that this product can more effectively extend its service life in rain, snow and other harsh weather conditions.
