Description
Technical Field
[0001] The utility model relates to the technical field of connectors, and more specifically to a novel waterproof power connector. Background Art
[0002] A waterproof connector usually refers to a power base connector with a new waterproof design. This connector uses new waterproof materials, structures or processes to improve the waterproof performance of the connector in a humid environment, thereby protecting the power transmission system from moisture and humidity. When the existing popular single-port or dual-port connectors transmit signals, when there is a need for multi-channel signal transmission, the number of PCB board end connections is increased to match the multi-channel signal transmission requirements. The number of PCB boards increases, the space occupied in the connector increases, and ultimately the size of the connector increases.
[0003] In view of the above problems, with regard to the technical problem that the existing connector increases the space occupied by the connector by adding a PCB board, thereby making the connector larger in size, after a lot of searches, a connector with patent number CN220306562U was found, comprising: a first terminal, a second terminal and a connector; the connector has a first end face and a second end face, and the first end face and the second end face are connected by a mounting groove, the mounting groove is used to install the first terminal or the second terminal, and the mounting grooves correspond to the holes on the first end face and the second end face, which are distributed in a rectangular shape; the mounting grooves are provided on the connector, the mounting grooves are distributed in a rectangular shape on the first end face and the second end face, and are used to install the first terminal and the second terminal. When in use, the number of mounting grooves and the corresponding number of first terminals and second terminals can be increased on the connector according to the law of rectangular distribution according to specific transmission needs, without increasing the number of PCB boards to meet the multi-channel transmission requirements. Compared with the connector with increased number of PCB boards, the connector has the advantages of more compact structure, convenient and quick use, and detachable, but the technical solution provided by the patent has the following problems:
[0004] (1) When the board end of the connector is not connected to the wire end, it cannot meet the waterproof requirements from the mating interface and cannot achieve the waterproof effect;
[0005] (2) After the line end and the board end are matched with each other, the joint cannot be waterproof, which affects the service life of the connector.
[0006] Before the board end of the utility model is matched with the wire end, it can meet the waterproofing of the whole process from the mutual matching interface to the PCB crimping end, and then cooperate with other assembly structures to achieve a waterproof effect. After the two cooperate with each other, the joint of the two can be waterproof.
