[0001] This application relates to the field of RJ45 connector technology, and particularly to an RJ45 connector with a welded structure. Background Technology

[0002] RJ45 connectors are a type of connector used in cabling systems for information sockets (i.e., communication leads). Currently, the conventional RJ45 connectors on the market use a fork-shaped terminal (two-prong or three-prong) to connect to the cable by piercing the copper core wire with a riveting process. This type of connection can cause the terminals to loosen due to thermal expansion and contraction during thermal shock, resulting in unstable cable connections.

[0003] Furthermore, when riveting pierces the core wire, terminal riveting rebound is prone to occur, which is more pronounced when riveting single-strand copper core wires, resulting in poor riveting consistency. Utility Model Content

[0025] RJ45 connectors are a type of connector used in cabling systems for information sockets (i.e., communication leads). Currently, the conventional RJ45 connectors on the market use a fork-shaped terminal (two-prong or three-prong) to connect to the cable by piercing the copper core wire with a riveting process. This type of connection can cause the terminals to loosen due to thermal expansion and contraction during thermal shock, resulting in unstable cable connections.

[0026] In addition, when riveting punctures the core wire, terminal riveting rebound is also prone to occur, which is more prominent when riveting single-strand copper core wire, and the riveting consistency is poor.

[0027] In view of this, this application proposes an RJ45 connector with a welded structure.

[0028] In the embodiments of this application, reference is made to Figures 1 to 5 The RJ45 connector with the above-mentioned welded structure includes: a housing 1, a plurality of S-type terminals 2 and a fixing cover 3; Several S-type terminals 2 are respectively disposed in terminal slots 101 inside the housing 1, and a fixing cover 3 is disposed at the opening end of the housing 1 to fix the S-type terminals 2. S-type terminal 2 is connected to external cables by soldering.

[0029] Specifically, several S-type terminals 2 are inserted into the pre-set terminal slots 101 inside the housing 1 to ensure that the terminal positions match the RJ45 standard interface. The fixing cover 3 is fastened to the open end of the housing 1, and the structure of the fixing cover 3 limits the movement of the S-type terminals 2 from coming out of the terminal slots 101 or shifting. The copper core of the external cable is directly connected to the welding end of the S-type terminal 2 using a welding process to complete the electrical connection between the cable and the connector. The dual constraint of the terminal slots 101 and the fixing cover 3 of the housing 1 restricts the displacement of the S-type terminals 2 in the up, down, left, right, and front-back directions, solving the problem of easy rebound and displacement of traditional crimped terminals. Welding replaces the crimping and piercing of traditional fork-type terminals, and metal bonding achieves a rigid connection between the terminal and the cable, avoiding the risk of loosening of the crimped structure under thermal shock.

[0030] In this embodiment, the S-type terminal 2 includes a contact portion 201, a soldering portion 202, and a transition portion 203. The contact portion 201 has a U-shaped structure and is used to contact the socket cable. The soldering portion 202 is used to solder external cables. The transition portion 203 connects the contact portion 201 and the soldering portion 202 at its two ends, respectively. The contact portion 201 faces the socket mating end of the housing 1 and is used to contact the terminal of the external RJ45 socket. The soldering portion 202 faces the cable entry end of the housing 1 and is used to solder external cables. The transition portion smoothly connects the contact portion 201 and the soldering portion 202, ensuring that the terminal is subjected to balanced force. The U-shaped structure has elastic deformation capability, and when mating with the socket, it can maintain stable contact pressure through slight deformation, avoiding poor contact caused by wear during insertion and removal.

[0031] In this embodiment, several S-type terminals 2 are distributed in a straight line at equal intervals, and the positions of the welding portions 202 of adjacent S-type terminals 2 are staggered. The several S-type terminals 2 are distributed in a straight line at equal intervals along the terminal slots 101 inside the housing 1 to ensure that the terminal spacing conforms to the international standard of RJ45 interface; during assembly, the welding portions 202 of adjacent S-type terminals are staggered in the direction perpendicular to the arrangement, such that the welding portions 202 of odd-numbered terminals are slightly higher and the welding portions of even-numbered terminals are slightly lower, to avoid the welding portions 202 overlapping on the same plane; the staggering of adjacent welding portions 202 can increase the welding operation space, prevent solder from flowing onto adjacent terminals during welding and causing short circuits, and at the same time facilitate the precise positioning of the welding gun or welding head.

[0032] In this embodiment, a first fixing groove 102 or a first fixing block 103 is provided on the housing 1 corresponding to the transition portion 203 of the S-type terminal 2, and the positions of the first fixing groove 102 and the first fixing block 103 are staggered. A second fixing block 302 is provided on the fixing cover 3 corresponding to the first fixing groove 102, and a second fixing groove 301 is provided on the fixing cover 3 corresponding to the first fixing block 103. The transition portion 203 of the S-type terminal 2 is clamped between the first fixing groove 102 and the second fixing block 302 or between the first fixing block 103 and the second fixing groove 301. The transition portion of the S-type terminal 2 is placed into the first fixing groove 102 of the housing 1 or abuts against the first fixing block 103, and then the fixing cover 3 is fastened, so that the second fixing block 302 is embedded in the first fixing groove 102 and the second fixing groove 301 is fitted around the first fixing block 103. The transition portion is clamped and fixed by the groove and block cooperation. Through the complementary structure of the groove and block of the housing 1 and the fixing cover 3, clamping force is applied from the upper and lower sides of the transition portion to limit the displacement of the terminal in the vertical direction. At the same time, the cooperation of the groove and block also limits the sliding of the terminal in the horizontal direction. And it can accurately fix each S-type terminal 2, prevent the S-type terminal 2 from shifting due to vibration and impact, and avoid poor contact. In addition, the cooperation of the groove and block has a positioning function, which can help the S-type terminal 2 to quickly find the correct position during assembly, improve assembly efficiency and consistency.

[0033] In this embodiment, the S-type terminal 2 is a one-piece structure made of phosphor bronze. Phosphor bronze has a high elastic modulus and can recover its original shape after repeated deformation (fatigue resistance), making it suitable as a contact terminal that needs to maintain contact pressure for a long time. At the same time, its surface easily forms an oxide film, which can prevent corrosion and improve environmental resistance. The one-piece structure can avoid structural weak points caused by splicing multiple parts, ensure the overall strength of the terminal, and reduce the risk of breakage.

[0034] In this embodiment, a shielding cover 4 is provided on the outer side of the housing 1, and a soldering pad 401 for connecting wires is provided on the shielding cover 4. As a metal conductor, the shielding cover 4 can block external electromagnetic interference signals from penetrating into the interior of the housing 1, avoiding interference with the network signals transmitted by the S-type terminal 2; at the same time, it can also prevent signals inside the housing 1 from leaking outward, avoiding interference with surrounding electronic equipment; by grounding the shielding cover 4 through the soldering pad 401, the interference current absorbed by the shielding cover 4 can be conducted to the ground, avoiding secondary radiation of the interference current inside the shielding cover 4, further improving the shielding effect.

[0035] In this embodiment, the shielding cover 4 is made of stainless steel or brass. Brass has high conductivity and strong ability to reflect and absorb electromagnetic waves, resulting in high shielding efficiency, making it suitable for EMI-sensitive scenarios. Stainless steel has excellent corrosion resistance and wear resistance, and can withstand harsh environments such as humidity and acids and alkalis, but its conductivity is lower than that of brass, resulting in slightly lower shielding efficiency, making it suitable for scenarios with harsh environmental conditions. Users can choose the material according to their actual needs.

[0036] In this embodiment, the shielding cover 4 is provided with locking blocks 402 on both sides opposite to the fixing cover 3, and the fixing cover 3 is provided with a slot 303 at the corresponding locking block 402. The mechanical engagement of the locking block 402 and the slot 303 enables the shielding cover 4 and the fixing cover 3 to be quickly connected without the need for additional fasteners. After the shielding cover 4 and the fixing cover 3 are connected, the displacement of the fixing cover 3 can be further restricted, which indirectly enhances the fixing effect of the fixing cover 3 on the S-type terminal 2, forming a linkage and stable structure of shielding cover 4-fixing cover 3-terminal.

[0037] In this embodiment, the S-type terminal 2 is connected to an external cable via HB welding. HB welding, through the synergistic effect of heating and pressurization, enables plastic deformation and diffusion at the contact surfaces of two different metals, forming a metallic bond connection. Compared to traditional riveting mechanical connections, this results in higher bonding strength and lower contact resistance.

[0038] In this embodiment, the welding temperature of the HB welding process is 200-300℃, and the welding time is 1-3s. The temperature range of 200-300℃ allows the contact surface between the copper core of the cable and the S-type terminal 2 (phosphor bronze) to fully melt, while avoiding excessive temperature that could cause the terminal or cable insulation layer to burn out; the welding time of 1-3s ensures sufficient metal diffusion to form a stable weld point, while avoiding excessive time that could cause oxidation or deformation of the weld point, and excessive time that could lead to a cold weld.

[0039] This application's technical solution comprises a housing, several S-type terminals, and a fixing cover. The S-type terminals are respectively positioned within terminal slots inside the housing, while the fixing cover is located at the open end of the housing to secure them. The S-type terminals are connected to external cables via welding. Each S-type terminal is inserted into a pre-set terminal slot inside the housing, ensuring the terminal position matches the RJ45 standard interface. The fixing cover is fastened to the open end of the housing, and its structural restraint prevents the S-type terminals from detaching or shifting from the terminal slots. A welding process is used to directly connect the copper core of the external cable to the welded end of the S-type terminal, completing the electrical connection between the cable and the connector. This structure fundamentally solves two major defects of traditional crimping structures: first, the problem of loosening and unstable cable connection caused by thermal shock; and second, the problem of poor connection consistency caused by crimping rebound.
