[0002] In the field of electrical connection technology, watertight connectors are widely used in electrical connections in harsh environments such as waterproof and dustproof. The traditional watertight connector has the following shortcomings:

[0003] The traditional watertight connector usually adopts a fixed pin jack design, that is, the position and size of the pin and the jack are strictly fixed, and the requirement for the production process is extremely high. Since the diameter of the pin and the jack is usually very small, such as a 1.02mm diameter pin, and the number is large, such as dozens of contact pieces, small deviations in the manufacturing process can cause the pin and the jack to fail to be connected smoothly, and even cause serious problems such as pin breakage.

[0004] In view of this, the present application is proposed. UTILITY MODEL CONTENTS

In detail, by setting the limiting groove 71, the limiting block designed on the pin 9 cooperates with the limiting groove 71 in the second through hole 7, which not only ensures the stability of the pin 9 during plugging and unplugging, but also allows the pin 9 to have a certain activity allowance within the limited range, so as to adapt to and allow certain manufacturing errors;

[0025] When the jack 8 and the pin 9 are connected, the width of the limiting groove 71 is greater than the width of the limiting block, so that the jack 8 can smoothly accommodate the pin 9 and maintain a certain tightness, facilitating plugging and unplugging operations; the compression nut 10 is arranged at the end of the first shell 1 and the second shell 2 respectively, for further fastening and sealing the entire connector to prevent moisture or other impurities from entering; the setting of the grounding copper ring 11 ensures the grounding performance of the connector, improving the safety and stability of electrical connection.
