Description

Technical Field

[0001] The present invention relates to an electrical connector, and more particularly to a vehicle-mounted waterproof connector and an assembly method thereof. Background Art

[0002] At present, the automotive industry has increasingly high requirements for the waterproof performance of connectors, and the demand is also increasing. However, existing vehicle-mounted connectors usually only have a single axial waterproof structure or need to be provided with a large number of sealing rings to achieve effective waterproofing. A waterproof connector with only a single axial waterproof structure cannot ensure the reliability of the connector during actual use. However, if a large number of sealing rings are provided, if one of the sealing rings fails, the waterproof performance of the entire waterproof connector will be lost, and the manufacturing cost of the product is relatively high, and the manufacturing process is relatively complex.

[0003] For example, a coaxial waterproof connector disclosed in Chinese Patent CN211655162U includes an outer housing and a coaxial cable. An outer conductor is provided inside the outer housing. The coaxial cable extends into the outer housing. The main body of the coaxial cable is located behind the outer conductor. The core of the coaxial cable extends into the outer conductor to be connected to an inner conductor provided inside the outer conductor. A compression tube for pressing and fastening the outer conductor to the coaxial cable is sleeved on the outer conductor. This invention uses too many sealing rings for waterproof treatment of the connector, resulting in too high cost. Moreover, if one of the sealing rings fails, the waterproof performance of the entire part will be lost.

[0004] For example, a reinforced waterproof connector disclosed in Chinese Patent CN210957097U includes a metal outer conductor and a metal inner conductor. The metal inner conductor is provided with a first groove and a second groove from outside to inside. A second rubber sealing ring is provided in the first groove, and a multi-tooth rubber sealing ring is provided in the second groove. A first insulating medium is sleeved on the metal inner conductor, and the first groove is wrapped inside. A first rubber sealing ring is provided on the first insulating medium. A second insulating medium is sleeved on the inner end of the metal inner conductor. The metal outer conductor is sleeved on the first insulating medium, the multi-tooth rubber sealing ring and the second insulating medium, and fixes the first insulating medium, the multi-tooth rubber sealing ring and the second insulating medium. A third groove is provided on the metal outer conductor, and a third rubber sealing ring is provided in the third groove. When the multi-tooth sealing ring of this invention is squeezed, the sealing ring is easily torn, resulting in the loss of the waterproof performance of the product.

[0005] Therefore, how to design a vehicle-mounted waterproof connector and an assembly method thereof, which can reduce the number of used sealing rings, reduce costs, reduce assembly processes, can provide extrusion protection for the sealing rings, and can effectively waterproof the product is an urgent matter to be solved, and has very important significance.
