After the metal shielding shell is sleeved on the insulating body, the two opposite sides of the metal shielding shell are bent downward to fit the insulating body and snapped together using a snap-on structure. Since the two sides of the metal shielding shell cannot be positioned, it is easy to shift and shake during the assembly process, resulting in a deviation in the position between the welding feet on the metal shielding shell and the external circuit board, thereby affecting the subsequent welding accuracy of the welding feet and the external circuit board, and reducing the quality of the finished product of the module connector.

This application provides a module connector to solve the technical problem that the metal shielding shell cannot be effectively positioned during the assembly process of the module connector, resulting in a position deviation between the welding pins on the metal shielding shell and the external circuit board, thereby affecting the subsequent welding accuracy between the welding pins and the external circuit board.

The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeatedly refer to numbers and/or letters in different examples. This repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and/or settings discussed.

For ease of description, spatially relative terms may be used in the text 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 spatially 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 movement state change, then these directional indications will 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..." can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

As shown in FIG1 , the existing traditional modular connector 100 ' (such as an RJ 45 modular connector) generally includes an insulating body 1 ', a terminal module, and a metal shielding shell 3 ' covering the insulating body 1 '. The insulating body 1 ' is provided with a receiving space 11 ' for receiving a 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 an external circuit board.

During the assembly process of the modular 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-fit 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 pins 31' on the metal shielding shell 3' and the external circuit board, thereby affecting the subsequent welding accuracy of the welding pins 31' and the external circuit board, and reducing the quality of the finished product of the module connector 100'.

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

FIG. 2 and FIG. 5 are a modular connector 100 provided in an embodiment of the present application, comprising an insulating body 1, a terminal module 2 and a metal shielding shell 3. As shown in FIG. 4, the insulating body 1 is provided with a first mating surface 11, a mounting surface 12 and a receiving space 13 penetrating the first mating surface 11, the mounting surface 12 is used to match with an external circuit board 200 (FIG. 2), and the receiving space 13 is used to receive a mating connector. As shown in FIG. 4, the terminal module 2 is at least partially mounted in the insulating body 1, and the terminal module 2 is electrically connected to the external circuit board 200. Please refer to Figures 2, 3 and 5 at the same time. The metal shielding shell 3 is sleeved on the insulating body 1 and connected to the insulating body 1 by snapping. The metal shielding shell 3 has a fixed surface 31, a positioning surface 32 connected to the fixed surface 31, a second butt surface 33 connected to the fixed surface 31, and a movable surface 34 connected to the second butt surface 33; the second butt 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 buckle structure 4 is provided between the movable surface 34 and the positioning surface 32, and a second buckle structure 5 is provided between the second butt surface 33 and the insulating body 1.

As shown in FIG. 4 and FIG. 5 , 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 second direction (e.g., the coordinate axis Y direction). As shown in Figures 2 and 3, 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. The fixing surface 31 and the positioning surface 32 limit the displacement of the insulating body 1 in the first direction (for example, the coordinate axis X direction) and the second direction (for example, the coordinate axis Y direction). The external circuit board 200 and the second mating surface 33 limit the displacement of the insulating body 1 in the third direction, playing 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.

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.

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

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

Optionally, as shown in FIG. 2 , a through groove 343 is provided at the connection between the movable surface 34 and the second butting surface 33 to increase the stress at the connection between the movable surface 34 and the second butting surface 33 and facilitate bending of the movable surface 34 .

In some embodiments, as shown in FIG. 3 , the first buckle structure 4 includes a first buckle 41 disposed on the positioning surface 32, and the two sides of the movable surface 34 are respectively bent to form a first buckle surface 42 abutting against the positioning surface 32, and the first buckle surface 42 is provided with a first slot 43 connected to the first buckle 41. Preferably, the first buckle surface 42 and the movable surface 34 are perpendicular to each other.

The first buckle 41 and the first slot 43 are connected by a snap connection to enhance the connection strength between the movable surface 34 and the positioning surface 32, thereby enhancing the overall structural strength of the modular connector 100.

In some embodiments, as shown in FIG. 3 and FIG. 4 , the second buckling structure 5 includes a second slot 51 disposed on the insulating body 1, and the two sides of the second abutting surface 33 are respectively bent to form a second buckling surface 52 abutting against the insulating body 1, and the second buckle 53 connected to the second slot 51 is disposed on the second buckling surface 52. Preferably, the second buckling surface 52 and the second abutting surface 33 are perpendicular to each other.

By the snap connection between the second snap buckle 53 and the second snap slot 51, the movement of the insulating body 1 in the second direction is limited, and the connection strength between the insulating body 1 and the second snap-fit surface 52 can be improved, thereby improving the overall structural strength of the modular connector 100.

In some embodiments, as shown in FIG. 3 , a positioning groove 321 is provided on the positioning surface 32, and a positioning block 14 is provided on the side of the insulating body 1 facing the positioning surface 32 and is connected to the positioning groove 321 by a clamp.

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 pre-positioning role in the process of pushing the insulating body 1 into the metal shielding shell 3.

In some embodiments, as shown in FIG. 3 , 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 connected to the welding foot 311. By providing the opening 15 to be connected to 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.

In some embodiments, one end of the welding foot 311 close to the external circuit board 200 is bent horizontally to form a welding surface 312 to increase the welding connection area. A welding groove 313 that can accommodate solder is provided on the welding surface 312 to enhance the connection strength.

The movable surface 34 is provided with a first elastic arm 341 extending into the receiving groove and used to abut against the built-in circuit board 22, so as to perform a grounding function for the built-in circuit board 22.

In some embodiments, a groove 342 is provided 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.
