[0029] The present utility model provides an RJ45 connector and an electrical port module. Figures 1 - 6 This is a specific embodiment of an RJ45 connector provided by the present utility model.

[0030] As Figures 1 - 3 , an embodiment of the present utility model provides an RJ45 connector 100, which includes a fixed bracket 1 and a plurality of pin pins 2. The pin pins 2 have a contact section 21 for connecting with an RJ45 connector and a welding portion 22 for connecting with a circuit board 3. The plurality of pin pins 2 are detachably inserted into the fixed bracket 1. Among them, the contact sections 21 are adjacent to each other to form a connector area 28, and the welding portions 22 are adjacent to each other to form a welding area 27. The connector area 28 and the welding area 27 are respectively exposed outside the fixed bracket 1.

[0031] It can be understood that the RJ45 connector 100 is connected to the circuit board 3 through the welding portion 22. After the RJ45 connector is in contact and conduction with the contact section 21, it can realize the function of conducting the network cable and the circuit board 3 as a connector.

[0032] In the present utility model, the multiple pin pins 2 are pluggably inserted on the fixed bracket 1. There is no need to fix the PIN pins by injection molding, which reduces the cost and is easy to operate. Moreover, the pin pin 2 has a contact section 21 for connecting with the RJ45 connector and a welding part 22 for connecting with the circuit board 3. The RJ45 connector 100 can be directly welded to the circuit board 3 through the welding part 22, without the need for other connection structures, reducing the use of molds and materials, greatly reducing the production cost, and reducing the production process.

[0033] Specifically, please refer to Figure 2 , in some embodiments, a plurality of installation channels 11 for accommodating the pin pin 2 are defined and arranged at intervals on the fixed bracket 1, and a fixing groove 12 communicated with the installation channels 11 is provided. The pin pin 2 further has a fixing section 23, the contact section 21 and the welding part 22 are respectively connected to two ends of the fixing section 23, and the fixing section 23 is detachably inserted into the fixing groove 12. When inserting and removing the pin pin 2, the fixing section 23 and the contact section 21 of the pin pin 2 can pass through the installation channel 11, and then the fixing section 23 is detachably inserted into the fixing groove 12.

[0034] Furthermore, a limiting structure 231 for detachably connecting with the fixing groove 12 is provided on the side of the fixing section 23. In this embodiment, the limiting structure 231 includes a limiting convex part protruding from the side of the fixing section 23. Preferably, the limiting convex parts are arranged on both sides of the fixing section 23. In this way, the detachable insertion of the pin pin 2 can be realized through the interference fit between the limiting convex part and the fixing groove 12.

[0035] Specifically, in some embodiments, a stepped part 13 is recessed on one side of the fixed bracket 1 close to the joint area 28. The installation channel 11 and the fixing groove 12 are respectively arranged on two adjacent stepped surfaces of the stepped part 13. This recessed area can provide an exposed deduction for the contact section 21 of the pin pin 2, reducing the volume of the fixed bracket 1, reducing the material cost, and being beneficial to the miniaturized design of the product.

[0036] Specifically, in order to ensure that the welding part 22 can be exposed outside the fixing bracket 1, in some embodiments, an extension section 25 is connected between the fixed section 23 and the welding part 22 for exposing the welding part 22 outside the fixing bracket 1. The extension section 25 is accommodated in the installation channel 11. In this way, the welding part 22 can be exposed through the extended part of the extension section, providing a welding space for the welding part 22 when it is welded to the circuit board 3 subsequently. It should be noted that the extension direction of the extension section 25 is not specifically limited. For example, in this embodiment, the extension section extends in an L shape and is adapted to the installation channel 11.

[0037] Specifically, in some embodiments, the pin 2 further includes a bending section 24 provided between the fixed section 23 and the contact section 21 and having a certain bending angle. The fixed section 23 and the contact section 21 are respectively connected to both ends of the bending section 24 and are located on the same side of the bending section 24. Since the contact section 21 is the part for contact connection with the RJ45 connector, when the RJ45 connector is inserted into the interface of the electrical port module, the RJ45 connector will press down the contact section 21. At this time, the bending section will provide sufficient upward elastic force (i.e., positive force) for the contact section 21, enabling the contact section 21 to have a good contact rate with the RJ45 connector, facilitating signal transmission. Moreover, by connecting the fixed section 23 and the contact section 21 through the bending section 24, the occupied space of the pin 2 can be reduced, which is beneficial to designing a smaller fixing bracket 1 adapted to the pin 2.

[0038] Specifically, please refer to Figure 4 , in some embodiments, a pre-pressure section 26 is connected to the end of the contact section 21 away from the bending section 24. The pre-pressure section 26 abuts against the inner side wall of the installation channel 11. In this way, the inner side wall of the installation channel 11 will limit the bending angle of the bending section 24 by abutting against the pre-pressure section 26, so that the contact section 21 is maintained within a certain inclination angle. Preferably, the inclination angle of the contact section 21 relative to the fixed section 23 through the bending section 24 is 20°.

[0039] Specifically, in some embodiments, the welding parts 22 in the welding area 27 are distributed to form a plurality of welding groups. Each welding group is distributed in sequence along the insertion and extraction direction. Each welding group includes a plurality of welding parts 22 that are sequentially and spaced apart along the adjacent direction of the welding parts 22 in the welding area 27. For example, please refer to Figure 2Specifically, in one embodiment, the welding group is provided with two groups, and the welding parts 22 of each group are distributed in sequence along the plug-in and pull-out direction, that is, it can be seen from the figure that the welding parts 22 of one group and the welding parts 22 of the other group are distributed in sequence in the plug-in and pull-out direction, and each welding group includes a plurality of welding parts 22 distributed in sequence along the spacing direction of each pin needle 2, so that adjacent welding parts 22 can be staggered in the plug-in and pull-out direction, thereby increasing the welding space, facilitating the welding process, and also facilitating the arrangement of the pads corresponding to the welding parts 22 on the circuit board 3.

[0040] Specifically, the fixing bracket 1 is an injection molded part, and a process groove 14 is provided on the fixing bracket 1. The process groove 14 can improve the deformation and shrinkage of the fixing bracket 1 caused by uneven wall thickness during the injection molding process.

[0041] See also Figure 6 The utility model also discloses an electrical port module, including a circuit board 3 and the above-mentioned RJ45 connector 100, the fixing bracket 1 is provided with a first positioning portion 15, the circuit board 3 is provided with a second positioning portion 31, the fixing bracket 1 is installed on the circuit board 3 and is positioned and matched by the first positioning portion 15 and the second positioning portion 31, and each of the pin needles 2 is respectively soldered to the circuit board 3 through the soldering portion 22.

[0042] Specifically, the first positioning portion 15 includes a positioning protrusion convexly provided on the fixing bracket 1, and the second positioning portion 31 includes a positioning hole provided on the circuit board 3. In this way, the relative position of the fixing bracket 1 and the circuit board 3 during the installation process is ensured through positioning and matching, so that the soldering portion 22 of the PIN needle can be accurately positioned and inserted into the soldering pad hole of the circuit board 3. Preferably, the cross-section of the positioning column is D-shaped.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
