Background
The existing pure electric vehicle with new energy is driven by electric energy, and a power system in the vehicle transmits the electric energy through a connector and a wiring harness, so that each power system in the vehicle requires that the assembly of the connector and the wiring harness needs to be waterproof. The compressor system of the new energy vehicle is an important power system. The compressor system of the new energy vehicle consists of a compressor body and a compressor controller, so that the controller is required to be incapable of feeding water when the vehicle is soaked in rainwater and washed by a high-pressure gun, and the product is prevented from being damaged. The control of the controller is debugged with the wire harness through the low-voltage connector, which requires the low-voltage connector to reach a waterproof grade IP67, and more highly requires the high-pressure water gun to reach a waterproof grade IP 69K.
The design scheme of the low-pressure connector of the existing new energy compressor controller is roughly divided into the following two types: 1. designing pins and a shell pin type, and then performing pin dispensing treatment; 2. the pin and the shell are designed in an injection molding mode. In the process of welding, maintaining and disassembling the pins of the connector in the scheme 1, the pins are easy to be knocked off, so that the air tightness of the connector is invalid, the waterproofness is reduced, and the use requirement cannot be met (IP 67); the connector of scheme 2 is the stitch and shell injection molding formula design, and the gas tightness of this scheme, waterproof nature uniformity can not reach the design requirement, and some connectors gas tightness are invalid, and the main reason is that there is cooling shrinkage stress in stitch and plastic, has minimum gap between stitch and the plastic, can't pass waterproof requirement (IP 67).
In view of the defects of the two schemes, the utility model aims to provide a connector with a structure of preventing a needle from falling off, and the waterproof performance of the connector reaches IP 67.

The low-voltage waterproof connector has the following beneficial effects:
1) the injection molding and anti-drop needle structure is adopted, repeated welding and maintenance can be carried out for many times, and pins cannot loosen or drop, so that the air tightness and the waterproof performance of the connector cannot be influenced.
2) The connector has good air tightness and waterproof performance reaching IP 67.
3) The stitch drawing force of the connector is high, the single stitch drawing force is more than 60N, and the stitch is more stable.
4) The arrangement of the bending does not adversely affect the air tightness and the water resistance of the connector.
5) The connector is wide in application range, and is suitable for other power supply systems of new energy vehicles.
