DETAILED DESCRIPTION

[0035] The utility model will be described in further detail in combination with the embodiments.

[0036] In order to solve the problems in the prior art, the basic idea of the utility model is that the rear end face of the rib plate on the shell can limit the forward movement of the limiting protrusion when the terminal module is assembled into the shell, thereby preventing the terminal module from deforming forward, and further preventing the grounding spring or the signal spring on the terminal module from being deformed and damaged by impacting the shell.

[0037] The specific embodiment 1 of the connector provided by the utility model is as follows:

[0038] The end of the connector matched with the adapter connector is defined as the front end, the plug-in direction of the connector is the first direction, the second direction and the third direction are perpendicular to each other and perpendicular to the first direction.

[0039] The connector comprises a shell 1 and a terminal module 2 inserted into the shell 1.

[0040] Referring to the accompanying drawings, Figure 3 The shell 1 comprises a front end wall 11, shell side walls 12 located at both ends of the front end wall 11 in the second direction, rib plates 13 located between the two shell side walls 12 and extending along the second direction and arranged at intervals in the third direction, and the space between adjacent rib plates 13 constitutes an insertion slot for the terminal module 2.

[0041] Referring to the accompanying drawings, Figure 4 The terminal module 2 comprises a sheet-shaped insulator 21, shielding sheets 22 located at both sides of the insulator 21 in the thickness direction, i.e. the third direction, ground terminals and signal terminals fixed on the insulator 21, the front ends of the ground terminals and the signal terminals protruding from the insulator 21 and forming grounding springs 25 and signal springs 26 respectively. The insulator 21 is provided with limiting protrusions 23 at both ends in the second direction, and the shell side wall 12 is provided with a clamping hole 14 for clamping with the limiting protrusion 23, and each limiting protrusion 23 corresponds to one clamping hole 14. In the process of inserting the terminal module 2 into the shell 1, the limiting protrusion 23 first pushes the shell side wall 12 apart in the second direction, and when the limiting protrusion 23 reaches the position of the clamping hole 14, the shell side wall 12 returns to its original state, and the limiting protrusion 23 is clamped with the clamping hole 14. The specific structure of the limiting protrusion 23 and the clamping hole is the prior art, which is not described here.

[0042] After the limiting protrusion 23 is clamped with the clamping hole 14, the terminal module 2 cannot move forward or backward relative to the shell 1. Specifically, the front end wall 11 of the limiting protrusion 23 is located behind the front side wall of the clamping hole 14, and the cooperation of the front end wall 11 of the limiting protrusion 23 and the front side wall of the clamping hole 14 prevents the terminal module 2 from moving forward relative to the shell 1 after being assembled in place.

[0043] The insulator 21 is integrally formed with a limiting protrusion 24 protruding from the insulator 21 in the third direction, and the limiting protrusion 24 is arranged on one side of the insulator 21. The limiting protrusion 24 has a rectangular cross section perpendicular to the third direction, i.e., the limiting protrusion 24 has a quadrangular prism structure. The shielding sheet 22 is provided with a through hole 224 corresponding to the limiting protrusion 24.

[0044] After the limiting protrusion 23 is engaged with the clamping hole 14, referring to Fig. 4, the rear end surface of the rib plate 13 can limit the forward movement of the limiting protrusion 24. The rear end surface of the rib plate 13 constitutes a stop surface for stopping the limiting protrusion 24 when the terminal module 2 is excessively inserted, and the surface of the limiting protrusion 24 corresponding to the stop surface is a matching surface. After the terminal module 2 is assembled with the shell 1, the limiting protrusion 24 is located behind the stop surface, and the distance between the front end of the limiting protrusion 24 and the stop surface is greater than or equal to zero, i.e., the limiting protrusion 24 is not in interference fit with the stop surface, so as to prevent the terminal module 2 from being difficult to assemble with the shell 1. Figure 6

[0045] The shielding sheet 22 on the side of the terminal module 2 where the limiting protrusion 24 is arranged includes a sheet body 221 and a plurality of connecting bodies 222 integrally connected with the sheet body 221. The connecting bodies 222 extend in the third direction and extend into the insulator 21 to be conductively connected with the grounding terminals. Specifically, the connecting bodies 222 are in interference fit with the corresponding openings arranged on the grounding terminals. The connecting bodies 222 are directly processed on the shielding sheet 22, referring to Fig. 6. Specifically, a U-shaped long hole is first punched on the shielding sheet 22, and then the tongue-shaped part surrounded by the long hole is bent towards the inner side of the shielding sheet 22 to form the connecting bodies 222. After the connecting bodies 222 are formed, a processing hole 223 is left at the original position. In order to reduce the processing procedures, the embodiment does not additionally arrange the through hole 224, but uses a part of the processing hole 223 as the through hole 224. Figure 5

[0046] On the insulator 21, referring to Fig. 7, a through hole 27 is arranged at the position corresponding to the opening, and the through hole 27 is a waist-shaped hole for the connecting body to pass through. One side wall of the through hole 27 is coplanar with one side wall of the limiting protrusion 24, so that the space of the through hole 223 can be maximally utilized, and the area of the matching surface on the limiting protrusion 24 is maximally expanded. Figure 7

[0047] ​​​The connecting body 222 on the shielding sheet 22 is arranged along the path of the grounding terminal, and one connecting body 222 is arranged at the front of each grounding terminal, and the machining hole 223 formed by machining the connecting body 222 is used as the through hole 224, so that the through hole 224 does not need to be separately formed, and the position of the through hole 224, that is, the position of the limiting protrusion 24, corresponds to each grounding terminal. Since the length of the grounding spring 25 is generally longer than that of the signal spring 26, the grounding spring 25 is more likely to hit the front end wall 11 of the shell 1 after the terminal module 2 is deformed, and the position of the limiting protrusion 24 corresponds to each grounding terminal, which can effectively prevent the terminal module 2 from deforming forward at each grounding terminal. In the embodiment, the limiting protrusion 24 is provided with three limiting protrusions 24, the three limiting protrusions 24 are arranged at intervals in the second direction, and one of the limiting protrusions 24 is located at the middle position of the insulator 21 in the second direction, and the other two limiting protrusions 24 are symmetrically arranged about the middle limiting protrusion 24, which improves the reliability of preventing the grounding terminal from deforming forward.

[0048] In other embodiments, the side wall of the limiting protrusion can also be coplanar with the side wall of the through hole.

[0049] In other embodiments, the limiting protrusion can also be provided with two, four or five, and the specific number can be set as needed. The limiting protrusion can also be provided with only one, and in this embodiment, the limiting protrusion needs to be provided at the middle position of the terminal module in the second direction. The limiting protrusion needs to be provided at least in the middle of the terminal module, so as to stop cooperation with the limiting protrusion when the terminal module is excessively inserted, and the middle of the terminal module refers to the middle of the front end of the terminal module.

[0050] In other embodiments, a through hole for the limiting protrusion to pass through can also be separately formed on the shielding sheet, so that the setting position of the limiting protrusion has more choices.

[0051] In other embodiments, the cross-sectional shape of the limiting protrusion can also be circular or triangular, and the specific shape can be set as needed. When the limiting protrusion is circular, it does not have a cooperation plane, and at this time, the outer peripheral wall of the limiting protrusion cooperates with the stop surface.

[0052] In other embodiments, the terminal module can also be provided with a shielding sheet on only one side. In this embodiment, the limiting protrusion can be provided on the side without the shielding sheet, so that the through hole does not need to be formed on the shielding sheet.

[0053] In other embodiments, the clamping protrusion can be provided on the shell, and the clamping hole can be provided on the insulator. In this embodiment, the clamping hole is a blind hole.

[0054] The specific embodiments of the terminal module provided by the utility model:

[0055] The terminal module is the terminal module in the specific embodiment of the connector, which is not described herein.

[0056] Finally, it needs to be explained that the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solution recorded in the foregoing embodiments can be modified without creative labor, or some technical features can be replaced equivalently. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
