[0026] like Figure 1 As shown, the present invention provides a connector 10, comprising a terminal module 1 and a housing 2 enclosing the terminal module 1. The gap between the terminal module 1 and the housing 2 is sealed by a seal 3, which encloses the same end of the terminal module 1 and the housing 2. By enclosing the terminal module 1 and the housing 2 with the seal 3, the reliability of the connection between the terminal module 1 and the housing 2 is improved, and the waterproof performance of the connector 10 is improved.

[0027] In the prior art, connectors need to be waterproofed during the production process. Specifically, after the terminal module and the housing are assembled, glue is injected into the gap between the terminal module and the housing. After standing and drying, the entire waterproofing process is completed. The existing waterproofing process requires a lot of steps, and each step has high requirements for the degree of refinement. The degree of refinement mainly includes the amount of glue, time, temperature, injection location, and operator proficiency. Once an error occurs in one of the steps, the waterproof performance of the connector will deteriorate, and it may even fail the waterproof performance test. Due to the numerous steps, the production efficiency of the connector is low.

[0028] Preferably, the seal 3 is injection molded. Direct waterproofing by injection molding has a simple process and therefore requires less refinement, which not only improves the waterproof performance of the connector 10 but also improves the production efficiency of the connector 10.

[0029] like Figure 2 Preferably, the housing 2 includes a first sub-housing 21 and a second sub-housing 22 connected to the first sub-housing 21. The cross-sectional area of ​​the first sub-housing 21 is larger than the cross-sectional area of ​​the second sub-housing 22. The first sub-housing 21 and the second sub-housing 22 are both hollow structures. Figure 1-2As shown, the second sub-housing 22 is wrapped by the seal 3 and the upper surface of the seal 3 is flush with the upper surface of the first sub-housing 21 , which not only reduces the volume of the connector 10 but also improves the reliability of the connection between the seal 3 and the housing 2 .

[0030] Specifically, the housing 2 is trumpet-shaped.

[0031] Preferably, the first sub-housing 21 and the second sub-housing 22 are an integrally formed structure, thereby improving the waterproof performance of the connector 10 .

[0032] like Figure 4 As shown, preferably, the terminal module 1 includes an insulating body 11 and a terminal 12 provided on the insulating body 11, the insulating body 11 includes a tongue plate 111 and a limiting portion 112 connected to the tongue plate 111, and the limiting portion 112 is used to abut against the end surface of the housing 2. Figure 2 As shown, the limiting portion 112 abuts against the end surface of the housing 2 , so that the terminal module 1 is always located in the housing 2 during the assembly process, thereby improving the assembly efficiency of the connector 10 .

[0033] Specifically, the height of the limiting portion 112 is higher than that of the tongue plate 111. When the tongue plate 111 passes through the housing 2, the protruding limiting portion 112 abuts against the end surface of the housing 2, so that the tongue plate 111 is always located in the housing 2, thereby improving the assembly efficiency of the connector 10.

[0034] like Figure 4 As shown, preferably, a positioning member 113 is provided on the limiting portion 112, and the positioning member 113 is used to abut against the inner wall of the sealing member 3 to prevent the sealing member 3 from moving. The positioning member 113 can prevent the sealing member 3 from moving, so that the sealing member 3 can reliably seal the gap between the terminal module 1 and the housing 2, thereby improving the waterproof performance of the connector 10.

[0035] Specifically, a positioning member 113 is provided on both the first end surface 1121 and the second end surface 1122 of the limiting portion 112. The positioning members 113 provided on the first end surface 1121 and the second end surface 1122 can further prevent the sealing member 3 from moving.

[0036] Preferably, the terminal module 1 and the housing 2 are interference fit. During the assembly process, the interference fit can automatically correct the assembly position of the terminal module 1, so that the terminal module 1 and the housing 2 achieve a tight assembly effect, so that the connector 10 after production has high consistency, thereby improving the quality of the connector 10.

[0037] Preferably, the tongue plate 111 and the limiting portion 112 are an integrally formed structure, thereby improving the strength of the terminal module 1 .

[0038] Injection molding process:

[0039] First, the terminal module 1 is assembled onto the housing 2 , and then the gap between the terminal module 1 and the housing 2 is sealed by the seal 3 through injection molding, and finally a semi-finished product after injection molding is obtained.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
