[0029] See Figures 1 to 7The figure shown is a schematic diagram of a preferred embodiment of the present invention.

The first terminal module 2 is assembled on the insulating body 1 and provides a contact portion 21 and a first splicing portion 22. The contact portion 21 is inclined in the plug cavity 11 of the insulating body 1 to obtain corresponding elasticity to achieve contact and conduction with the external plug (crystal plug). The second terminal module 3 is assembled on the insulating body 1 and provides a welding portion 31 and a second splicing portion 32. The welding portion 31 extends from the insulating body 1 for welding assembly; as shown in FIG. Figure 1 、 2 As shown in , 4, and 6, the soldering portion 31 is designed to meet the requirements of the SMT process. Figure 7 As shown, the soldering portion 31 is designed to meet the requirements of the DIP process. Different types of soldering portions can be selected according to actual needs and are interchangeable. The second splicing portion 32 is in contact with the first splicing portion 22 and is electrically connected to form the first terminal module 2 and the second terminal module 3. By modularizing the terminals into segments and assembling them onto the insulating body before conducting them together, the terminal molding dimensions and structure are more stable during production, which is conducive to production and assembly. Modular assembly facilitates automated production, ensures assembly structure and quality, and is also convenient for disassembly and maintenance. The second terminal module can be selectively assembled to meet the production requirements of the SMT process or the DIP process. It is interchangeable and standardized, greatly improving the production and implementation of the connector and reducing inventory backlogs in accessory production.

[0030] Figures 1 to 6As shown, in this embodiment, the first terminal module 2 includes a first tongue 23 and multiple first conductors 24 that are bent to form a contact portion 21 and a first splicing portion 22. The multiple first conductors 24 are arranged and injection-molded integrally with the first tongue 23. As shown in the figure, the contact portion 21 extends from the first tongue 23 and is bent accordingly, while the first splicing portion 22 is positioned on the first tongue 23 and exposed from the corresponding side of the first tongue 23 for contact and conduction. The second terminal module 3 includes a second tongue 33 and multiple second conductors 34 that are bent to form a soldering portion 31 and a second splicing portion 32. The multiple second conductors 34 are arranged and injection-molded integrally with the second tongue 33. As shown in the figure, the second tongue 33 is injection-molded around the middle section of the second conductor 34, while the soldering portion 31 and the second splicing portion 32 extend from the two side ends of the second tongue 33. The number and arrangement of the first and second conductors 24 and 34 match each other to meet the requirements of constructing a corresponding RJ45 connector. A first implantation groove 12 and a second implantation groove 13 are provided on the insulating body 1, and the first implantation groove 12 is connected with the plug cavity 11 and the second implantation groove 13 respectively; in this way, the first terminal module 2 can be implanted and installed on the insulating body 1 corresponding to the first implantation groove 12, and the second terminal module 3 can be implanted and installed on the insulating body 1 corresponding to the second implantation groove 13. The second splicing part 32 and the first splicing part 22 are in contact and conductive in the area where the first implantation groove 12 and the second implantation groove 13 are connected, thereby achieving modular assembly implementation and being detachable, and making the product manufacturing and use more flexible.

[0031] As shown in the figure, the insulating body 1 has a front end 14 and a rear end 15. The plug-in cavity 11 is a concave hole that is concave from the front end and extends toward the rear end. The first implantation groove 12 and the second implantation groove 13 are opened from the rear end and extend toward the front end, and the first implantation groove 12 partially overlaps with the plug-in cavity 11. The first implantation groove 12 and the second implantation groove 13 form a back-to-back relationship separated by a back plate 16. The area where the first implantation groove 12 and the second implantation groove 13 communicate is a notch that is partially hollowed out of the back plate 16. The structure is simple and compact, and is also conducive to assembly implementation. The cross-sectional shape of the first implantation groove 12 in the figure is a U-shaped shape, while the cross-sectional shape of the second implantation groove 13 is a C-shaped shape, which can obtain the corresponding assembly limit. Furthermore, a positioning rib 161 is provided on the side of the back plate 16 facing the first implantation groove 12, and the positioning rib 161 extends along the extension direction of the first implantation groove 12. A positioning groove 231 is provided on the first tongue piece 23 of the first terminal module 2. When the first terminal module 2 is implanted into the first implantation groove 12, the positioning rib 161 cooperates with the positioning groove 231 to guide and limit. At the same time, an anti-retraction clamping structure is also provided between the first implantation groove 12 and the first tongue piece 23 to stabilize the implantation depth of the first terminal module 2 and prevent it from loosening and exiting, and further stabilize the contact portion 21 in an inclined posture in the connector cavity 11 of the insulating body 1, which is conducive to product plugging and use. The back plate 16 is provided with a backstop groove 162 on the side facing the second implantation groove 13, and a backstop protrusion 331 is provided on the corresponding side of the second tongue piece 33 of the second terminal module 3. The second tongue piece 33 is also provided with symmetrically arranged wings 332. When the second terminal module 3 is implanted in the second implantation groove 13, the wings 332 are correspondingly inserted into the preset card groove 131 inside the second implantation groove 13, and the backstop protrusion 331 slides into the backstop groove 162 and forms an anti-backstop connection, multi-point positioning and limiting, improving assembly accuracy and stability. The first implantation groove 12 is also provided with a top pressure rib 121. The top pressure rib 121 faces the back plate 16 at a distance. The top pressure rib 121 cooperates with the back plate 16 to clamp the first tongue piece 23, and a limiting rib groove 232 is provided on the first tongue piece 23 corresponding to the top pressure rib 121. The cross-section of the top pressure rib 121 and the limiting rib groove 232 in the figure is V-shaped, which increases support and limiting. The anti-retraction clamping structure comprises an anti-retraction tooth 122 provided at the end of the first implantation slot 12. This tooth 122 is formed from the elastic adhesive remaining after a partial cut at the rear end of the insulating body 1, making it easy to manufacture. After the first tongue 23 is implanted in the first implantation slot 12, the anti-retraction tooth 122 supports the implanted end of the first tongue 23, similarly achieving multi-point positioning and limiting, improving assembly accuracy and stability. This ensures relative stability between the components of the connector product after assembly, a stable and durable electrical connection between the first terminal module 2 and the second terminal module 3, and excellent shock resistance.

[0032] Figure 1 、 2As shown in Figures 3 and 4, the first splicing portion 22 is a flat surface where the corresponding section of the first conductor 24 is embedded in the first tongue 23 and partially exposed. The second splicing portion 32 is an elastic head formed by bending the corresponding section of the second conductor 34 from the second tongue 33. Due to its elasticity, the second splicing portion 32 continuously abuts against the first splicing portion 22, achieving contact and conductive connection with the first splicing portion 22. This structural design facilitates the production of the first terminal module 2 and the second terminal module 3, ensures electrical connection between the first terminal module 2 and the second terminal module 3, and prolongs the product life.

[0033] The utility model achieves the following beneficial effects by modularizing the terminals into segments, assembling them onto the insulating body, and then conducting and connecting them together:

[0034] 1. The terminal forming size and structure are stable, which is conducive to production and assembly;

[0035] 2. Modular assembly facilitates automated production, ensures assembly structure and quality, and is easy to disassemble and maintain;

[0036] 3. The second terminal module can be selectively assembled to meet the production needs of SMT or DIP processes. It is interchangeable and standardized, greatly improving the production and implementation of connectors and reducing inventory backlogs in accessory production.
