[0012] Furthermore, in some embodiments, the side wall of the housing is provided with an inwardly bent insert-type buckle, and the base is provided with a positioning block that matches the insert-type buckle, the positioning block being engaged in the insert-type buckle.

[0013] Furthermore, in some embodiments, the base is provided with a plurality of LED lights, and a spacer strip is provided between adjacent LED lights, the spacer strip being disposed on the base;

[0015] Furthermore, in some embodiments, the insert buckle adopts a U-shaped buckle (7-shaped buckle) structure, the positioning block is a right-angled trapezoid, the sloping waist of the positioning block faces the edge of the shell, and the right-angled waist of the positioning block is away from the edge of the shell;

[0016] The hook surface at the front end of the insert-type buckle is pressed against the right-angle waist of the positioning block.

[0017] Furthermore, in some embodiments, the insulating seat includes a middle horizontal seat, which is disposed below the upper seat body, and the middle rear wall of the middle horizontal seat is disposed adjacent to the rear wall plate;

[0018] The central cross seat has longitudinally distributed grooves.

[0019] Furthermore, in some embodiments, the groove is disposed between adjacent terminals of the terminal assembly, with the bottom end of the groove disposed in the middle cross seat and the top end of the groove extending into the upper seat body;

[0028] The grooves are located at both ends in the upper seat and the middle horizontal seat.

[0029] This invention is applied to network connectors. By using the spacer structure between the upper rear wall and the rear wall plate (equivalent to digging a groove in the insulating base), the pressure resistance of the terminal assembly and the housing is optimized to meet the pressure resistance requirements and increase the pressure resistance specification. Digging a groove or directly hollowing out the insulating base results in high air resistance and avoids short circuits under high voltage (pressure resistance) conditions.

[0045] The present invention includes a housing 12, a base 14 embedded within the housing 12, an insertion interface 15 at one end of the base 14, and an opening in the housing 12 corresponding to the insertion interface 15. An inwardly bent insert-type buckle 13 is provided on the side wall of the housing 12, and a positioning block 16 corresponding to the insert-type buckle 13 is provided on the base 14, the positioning block 16 being engaged in the insert-type buckle 13. A frame 11 is fitted onto the outer side of the housing 12 near the insertion interface 15, and a rear wall plate 36 is provided on the side of the housing 12 away from the insertion interface 15.

[0046] Furthermore, in one embodiment, the base 14 is provided with a plurality of LED lights 18, and a spacer 17 is provided between adjacent LED lights 18. The spacer 17 is provided on the base 14, and the top surface of the housing 12 is provided with a guide groove 35 facing the spacer 17. The tail end of the spacer 17 is located at the end of the base 14 away from the insertion interface 15, that is, the rear end of the spacer 17 is located adjacent to the end of the base 14 away from the insertion interface 15, and the other end (front end) of the spacer 17 is inserted into the guide groove 35.

[0047] The base 14 is provided with a terminal assembly 31, which includes a contact portion 32 and a solder portion 33. The contact portion 32 is disposed in the insertion interface 15. The end of the contact portion 32 away from the insertion interface 15 is provided with a solder portion 33 that is bent upward. A fixing cross plate 19 is provided on the contact portion 32, and the contact portion 32 is embedded in the fixing cross plate 19. The fixing cross plate 19 is disposed in the base 14.

[0048] The welding part 33 is provided with an insulating seat 21, and the welding part 33 is embedded and formed on the insulating seat 21; the top end of the welding part 33 passes through the insulating seat 21 and is positioned above the insulating seat 21, and the insulating seat 21 is positioned in the base 14.

[0049] The insulating base 21 includes a middle horizontal base 23 and an upper base 22. The middle rear wall 25 of the middle horizontal base 23 is disposed adjacent to the rear wall plate 36. The middle horizontal base 23 is provided with longitudinally distributed grooves 27. The grooves 27 are disposed between adjacent terminals of the terminal assembly 31. The bottom end of the groove 27 is disposed in the middle horizontal base 23, and the top end of the groove 27 extends into the upper base 22. The top end of the groove 27 is disposed on the upper base 22.

[0050] Furthermore, in one embodiment, a stepped platform 26 with a certain distance is provided between the upper rear wall 28 and the middle rear wall 25 of the upper seat 22. Side protrusions 24 protruding backward are provided on both sides of the upper seat 22. The protruding end of the side protrusion 24 is disposed adjacent to the rear wall plate 36. The end of the side protrusion 24 away from the upper seat 22 is located on the same plane as the middle rear wall 25, that is, the protruding end of the side protrusion 24 abuts against the middle rear wall 25 on the rear wall plate 36.

[0051] Furthermore, in one embodiment, the side protrusion 24 extends out from the rear end of the upper seat 22 and abuts against the rear wall panel 36, see attached figure. Figure 10 As shown, the distance D between the end of the upper rear wall 28 and the end face of the side protrusion 24 is 0.25–0.4 mm, that is, the length of the side protrusion 24 extending from the upper rear wall 28 (equivalent to the distance D) is 0.25–0.4 mm; this ensures that the upper rear wall 28 and the rear wall plate 36 have a certain gap, see Appendix Figure 9As shown, in other words, there is a certain distance between the upper rear wall 28 and the rear wall plate 36. The distance D between the upper rear wall 28 and the rear wall plate 36 is equal to the length of the side protrusion 24, that is, the distance D between the upper rear wall 28 and the rear wall plate 36 is 0.25~0.4mm.

[0052] In other words, the distance D between the upper rear wall 28 and the rear wall plate 36 is equal to the distance D between the end of the rear wall 28 and the end face of the side protrusion 24.

[0053] Furthermore, preferably, the side protrusion 24 extends 0.3 mm from the upper rear wall 28 by a length D, and the distance D between the upper rear wall 28 and the rear wall plate 36 is 0.3 mm.

[0054] The groove 27 is located at both ends in the upper seat 22 and the middle horizontal seat 23; the middle horizontal seat 23 is provided with a lower seat 29 on the side away from the upper seat 22, and the lower seat 29 is located below the middle horizontal seat 23.

[0055] This invention is applied to network connectors. By using the spacing structure between the upper rear wall 28 and the rear wall plate 36 (equivalent to creating a groove in the insulating base 21), the pressure resistance of the terminal assembly 31 and the housing 12 is optimized to meet the pressure resistance requirements and increase the pressure resistance specification. Because of the injection molding process, the injection block will expose the terminals. If the iron shell of the housing 12 is too close to the terminals, it will affect the electrical characteristics. Therefore, creating a groove or directly hollowing out the insulating base 21 results in high air resistance and avoids short circuits under high voltage (pressure resistance) conditions.

[0056] Furthermore, in one embodiment, the top end of the groove 27 is located in the upper seat 22, the bottom end of the groove 27 is located in the middle cross seat 23, and the groove 27 is longitudinally arranged across the adjacent portion of the upper seat 22 and the middle cross seat 23.

[0057] A spacer strip 17 is provided next to (between) the LED lights 18. Several spacer strips 17 are arranged in parallel on the base 14. The spacer strips 17 improve the crosstalk interference between the LED lights 18.

[0058] The insert-type buckle 13 (U-shaped buckle, side-rotating Π-shaped buckle) design optimizes assembly and prevents deformation of the metal shell during assembly. The insert-type buckle 13 matches the corresponding positioning block 16, which is a right-angled trapezoid with its sloping waist facing the edge of the shell 12. Figure 7 As shown, the right-angled waist of the positioning block 16 is away from the edge of the housing 12. The hook and latch surface of the insert-type buckle 13 presses against the right-angled waist of the positioning block 16.

[0059] The welding end 33 is wide in the middle and narrow at both ends, and the middle section of the welding end 33 has a perforation; that is, the welding end 33 has a perforated extrusion structure; furthermore, the extrusion structure of the welding end 33 is a fisheye structure.
