[0019] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely below with the embodiment.

[0020] EMBODIMENT

[0021] As Figure 1 , Figure 2 , Figure 3 Indicated, Figure 1 It shows the overall schematic diagram of the connector in the embodiment. Figure 2 It shows the explosion schematic diagram of the connector in the embodiment. Figure 3 It shows the cross-sectional structure schematic diagram of the connector in the embodiment.

[0022] The device comprises:

[0023] Shell assembly 10 and terminal assembly, the shell assembly 10 includes extension shell 11 and outer shell 12 arranged in sequence in the outside of terminal assembly, and the terminal assembly includes extension end 201, and the extension end 201 extends from one end of shell assembly 10 to the outside of shell assembly 10.

[0024] A waterproof glue 32 is arranged at the end of the extension shell 11 close to the extension end 201 to seal the gap between the extension end 201 and the extension shell 11.

[0025] A waterproof ring 31 is arranged at the end of the extension shell 11 away from the extension end 201.

[0026] Specifically, the extension shell 11 and the outer shell 12 are integrated by laser welding, and the whole is waterproof and dustproof; the extension shell 11 and the outer shell 12 are provided with a welding joint;

[0027] The waterproof ring 31 is arranged to enable the contact surface of the connector and the equipment to adopt elastic contact, and the waterproof ring 31 can be deformed to enable the connector and the equipment to be assembled to form a closed dustproof and waterproof surface, which is convenient to assemble and reliable in waterproofing. The terminal assembly is integrally formed by inlaying to achieve dustproof and waterproofing. The end of the extension shell 11 close to the extension end 201 is filled with waterproof glue 32 to seal the gap between the extension end 201 and the extension shell 11, which can further improve the dustproof and waterproof effect to avoid water entering from the tail end of the connector and causing safety hazards. The waterproof ring 31 is a solid elastic body.

[0028] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 1 Fig. 1 shows a schematic diagram of the whole connector in the embodiment; Figure 2 Fig. 2 shows an exploded schematic diagram of the connector in the embodiment; Figure 3 Fig. 3 shows a schematic diagram of the cross-sectional structure of the connector in the embodiment;

[0029] The terminal assembly includes a main body 21 and a contact part 22, and the contact part 22 is connected with a two-shot module, which is formed by embedding a terminal group one 23, a center piece 24 and a terminal group two 25;

[0030] The terminal group one 23 is formed by embedding the upper row of terminals, and the terminal group two 25 is formed by embedding the lower row of terminals.

[0031] The two-shot module is formed by embedding once and twice. Before the first shot, the upper row of terminals and the lower row of terminals are optimized by computer-aided engineering (CAE) simulation. In the process after the optimization, the terminal stamping die adopts a double-belt paving type to simultaneously produce the upper row of terminals and the lower row of terminals. Then, in the first shot, the upper row of terminals and the lower row of terminals adopt an unbalanced cavity structure, and the cavity is designed in a hot runner type. After molding, the terminal group one 23 and the terminal group two 25 are obtained. In the second shot, the terminal group one 23, the center piece 24 and the terminal group two 25 after the first shot are sequentially clamped together, and then the whole is integrally formed by embedding.

[0032] The waterproof ring 31 is sleeved on the limiting end 110.

[0033] In order to avoid the waterproof ring 31 from being separated from the extension shell 11, with reference to Figure 1 and Figure 3 , the extension shell 11 is outwardly protruded at one end away from the extension end 201 to form the limiting end 110, the waterproof ring 31 is limited by the limiting end 110, and the gap between the shell assembly 10 and the equipment is sealed, so that the elastic contact is achieved.

[0034] Working principle: the waterproof ring 31 is arranged, so that the contact surface of the connector and the equipment can adopt elastic contact, the waterproof ring 31 can be deformed, so that the connector and the equipment are assembled to form airtight dustproof and waterproof, the waterproof adhesive 32 is arranged, and the dustproof and waterproof effect can be further improved, so that water is prevented from entering from the tail end of the connector, and a safety hazard is avoided.

[0035] The above embodiments are only used to illustrate the technical solutions of the utility model, and not limit them.
