[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0031] like Figure 1 As shown, the existing modular connector 100' (such as RJ 45 modular connector) generally includes an insulating body 1', a terminal module and a metal shielding shell 3' covering the insulating body 1', and the insulating body 1' is provided with a receiving space 11' for receiving the docking connector. In order to improve the performance of the modular connector, the terminal module also includes a built-in circuit board electrically connected to the external circuit board.

[0032] During the assembly process of the module connector 100', the metal shielding shell 3' and the insulating body 1' are generally installed in an up-and-down plug-in manner. The metal shielding shell 3' is a square shell, and the two opposite sides of the metal shielding shell 3' are usually designed to be bendable. After the metal shielding shell 3' is sleeved on the insulating body 1', the two opposite sides of the metal shielding shell 3' are bent downward to fit the insulating body 1' and buckled using a snap structure. Since the two movable sides of the metal shielding shell 3' cannot be positioned, it is easy to shift and shake during the assembly process, resulting in a position deviation between the welding pin 31' on the metal shielding shell 3' and the external circuit board, thereby affecting the subsequent welding accuracy of the welding pin 31' and the external circuit board, and reducing the quality of the finished product of the module connector 100'.

[0033] In order to solve the technical problem in the prior art that the metal shielding shell cannot be effectively positioned, resulting in a position deviation between the welding feet on the metal shielding shell and the external circuit board, thereby affecting the subsequent welding accuracy between the welding feet and the external circuit board, the present application provides a module connector that can effectively position the metal shielding shell, reduce the position error between the welding feet on the metal shielding shell and the external circuit board, improve the subsequent welding accuracy between the welding feet and the external circuit board, and ensure the finished product quality of the module connector.

[0034] Figures 2 to 5 A module connector 100 provided for an embodiment of the present application includes an insulating body 1, a terminal module 2 and a metal shielding shell 3, the insulating body 1 is provided with a first docking surface 11, a mounting surface 12 and a receiving space 13 penetrating the first docking surface 11, the mounting surface 12 is used to cooperate with an external circuit board 200, and the receiving space 13 is used to receive a docking connector; the terminal module 2 is at least partially installed in the insulating body 1, and the terminal module 2 is electrically connected to the external circuit board 200; the metal shielding shell 3 is sleeved on the insulating body 1 and is snap-connected to the insulating body 1, the metal shielding shell 3 has a fixed surface 31, a positioning surface 32 connected to the fixed surface 31, a second docking surface 33 connected to the fixed surface 31 and a movable surface 34 connected to the second docking surface 33; the second docking surface 33 is arranged away from the external circuit board 200, and the movable surface 34 can be bent toward the inside of the metal shielding shell; a first buckling structure 4 is provided between the movable surface 34 and the positioning surface 32, and a second buckling structure 5 is provided between the second docking surface 33 and the insulating body 1.

[0035] During the assembly process, the terminal module 2 is first installed in the insulating body 1, and then the mounting surface 12 of the insulating body 1 is placed toward the external circuit board 200, and then the metal shielding shell 3 is pushed toward the insulating body 1 along the first direction. A limiting space is formed between the external circuit board 200, the fixing surface 31 and the positioning surface 32, so that the insulating body 1 is located in the limiting space, and the fixing surface 31 and the positioning surface 32 limit the displacement of the insulating body 1 in the first direction and the second direction. The external circuit board 200 and the second docking surface 33 limit the displacement of the insulating body 1 in the third direction, which plays a positioning role, thereby reducing the position error between the welding foot 311 on the metal shielding shell 3 and the external circuit board 200, improving the subsequent welding accuracy of the welding foot 311 and the external circuit board 200, and ensuring the finished product quality of the module connector 100.

[0036] Optionally, the first direction is the X-axis shown in the figure, the second direction is the Y-axis shown in the figure, and the third direction is the Z-axis shown in the figure.

[0037] Furthermore, the bent movable surface 34 and the fixed surface 31 are arranged opposite to each other and are respectively located on both sides of the first direction, two positioning surfaces 32 are provided and are respectively located on both sides of the second direction, and the first direction and the second direction intersect.

[0038] The bent movable surface 34 and the fixed surface 31 limit the displacement of the insulating body 1 in the first direction, and the two positioning surfaces 32 limit the displacement of the insulating body 1 in the second direction, so that the installed insulating body 1 is not easy to move, further ensuring the finished product quality of the module connector 100.

[0039] Alternatively, if Figure 2 As shown, a through groove 343 is provided at the connection between the movable surface 34 and the second butt joint surface 33 to increase the stress at the connection between the movable surface 34 and the second butt joint surface 33 and facilitate bending of the movable surface 34 .

[0040] In some embodiments, Figure 3 As shown, the first buckle structure 4 includes a first buckle 41 disposed on the positioning surface 32, and both sides of the movable surface 34 are bent to form first buckle surfaces 42 abutting against the positioning surface 32, and the first buckle surface 42 is provided with a first slot 43 that is buckled and connected to the first buckle 41. Preferably, the first buckle surface 42 and the movable surface 34 are perpendicular to each other.

[0041] The first buckle 41 and the first slot 43 are connected by a snap connection to improve the connection strength between the movable surface 34 and the positioning surface 32 , thereby improving the overall structural strength of the module connector 100 .

[0042] In some embodiments, Figure 3 and Figure 4 As shown, the second buckling structure 5 includes a second slot 51 provided on the insulating body 1, and the two sides of the second docking surface 33 are respectively bent to form a second buckling surface 52 abutting against the insulating body 1, and the second buckling surface 52 is provided with a second buckle 53 that is buckled and connected to the second slot 51. Preferably, the second buckling surface 52 and the second docking surface 33 are perpendicular to each other.

[0043] The second buckle 53 and the second slot 51 are connected by a snap connection to limit the movement of the insulating body 1 in the second direction, thereby improving the connection strength between the insulating body 1 and the second buckling surface 52 and further improving the overall structural strength of the module connector 100 .

[0044] In some embodiments, Figure 3 As shown, a positioning groove 321 is provided on the positioning surface 32 , and a positioning block 14 which is snap-connected with the positioning groove 321 is provided on one side of the insulating body 1 facing the positioning surface 32 .

[0045] The clamping connection between the positioning block 14 and the positioning groove 321 can limit the displacement of the insulating body 1 in the second direction, and can play a role of pre-positioning when the insulating body 1 is pushed into the metal shielding shell 3.

[0046] In some embodiments, Figure 3 As shown, a welding foot 311 is provided at one end of the fixing surface 31 close to the external circuit board 200, and an opening 15 is provided on the insulating body 1 to be clamped and connected with the welding foot 311. By providing the opening 15 to be clamped and connected with the welding foot 311, the welding point between the external circuit board 200 and the metal shielding shell 3 is positioned to prevent the welding foot 311 from deviating, thereby improving the welding accuracy of the welding foot 311 and the external circuit board 200.

[0047] In some embodiments, one end of the soldering foot 311 close to the external circuit board 200 is bent transversely to form a soldering surface 312 to increase the soldering connection area. A soldering groove 313 for accommodating solder is provided on the soldering surface 312 to enhance the connection strength.

[0048] In some embodiments, Figure 5 As shown, the terminal module 2 includes an insulating main body 21, a built-in circuit board 22 installed on the insulating main body 21, and a terminal module 23 installed on the insulating main body 21. The built-in circuit board 22 and the terminal module 23 are electrically connected. A receiving groove for accommodating the built-in circuit board 22 is provided on the insulating body 1, and a first elastic arm 341 extending into the receiving groove and used to abut against the built-in circuit board 22 is provided on the movable surface 34 to perform a grounding function for the built-in circuit board 22.

[0049] In some embodiments, a groove 342 is formed on the first elastic arm 341 to form a plurality of elastic contacts. Compared with the traditional one-piece contact, the multi-contact design can reduce the risk of poor grounding of the product due to one of the contacts not being in contact.

[0050] In some embodiments, the second docking surface 33 is provided with a second elastic arm 331 extending into the accommodating space 13 and used to abut against the docking connector to perform a grounding function for the docking connector.
