The connector includes a terminal module, and electrical connection is achieved through a circuit board on the terminal module. Among them, the terminal module includes a base shell and a terminal seat for mounting the circuit board. The terminal seat is assembled in the base shell. However, it is found in actual use that after the terminal seat is welded to the PCB board, the force is uneven, the terminal seat is prone to position deviation, the electrical connection pins are not stably connected to the PCB board, and the PCB board is damaged. Content of the Utility Model

[0003] Aiming at the shortcomings of the above-mentioned existing technologies, the purpose of the utility model is to provide a connector terminal seat that has uniform force with the PCB board, stable connection and is not easy to deviate, and can also make the PCB board safer to use.

[0004] The technical solution adopted by the utility model to solve its technical problems is a connector terminal seat, which includes a seat body and a plurality of terminals. The seat body includes a vertical plate and a horizontal plate. The horizontal plate is connected to the left or right side surface of the vertical plate. The terminals are arranged side by side on the vertical plate, and the lower ends are horizontally bent outward to form horizontal welding feet. At least two support members are connected to the distal end of the bottom of the horizontal plate. The support members are arranged side by side at intervals in the front and back. The support members are made of metal materials, and the lower ends are horizontally bent in the opposite direction to the horizontal welding feet to form horizontal support feet. The bottom of the horizontal support feet and the horizontal welding feet are at the same height.

[0005] Advantages of adopting the above technical solution: By providing support members made of metal materials, the horizontal support feet of the support members can be welded to the PCB board through a welding process to form auxiliary support after the horizontal welding feet and the PCB board are welded. The connection of the terminal seat is stable and the force is more uniform. The terminal seat is not easy to deviate during use, which can effectively ensure the service life of the PCB board, and the overall structure design is reasonable.

[0006] Further, a support block is also provided at the connection between the bottom of the horizontal plate and the corresponding support member. The bottom of the support block is flush with the bottom of the vertical plate.

[0007] Advantages of adopting the above technical solution: By providing a support block flush with the bottom of the vertical plate, the support member can be more stably connected to the horizontal plate, and the use effect is better.

[0008] Further, limiting blocks are arranged at intervals in the front - rear direction at the bottom of the transverse plate. The limiting blocks are arranged inside the supporting blocks and are used to limit excessive deformation of the horizontal support feet and the horizontal welding feet.

[0009] Advantages of adopting the above - mentioned technical solution: The limiting blocks can effectively prevent the horizontal support feet and the horizontal welding feet from being deformed due to excessive force, ensuring the safety of use and having a reasonable structural design.

[0010] Further, the limiting blocks are arranged side by side. First connecting studs and second connecting studs are respectively arranged at the bottoms of the limiting blocks. The heads of the first connecting stud and the second connecting stud are both conical, and the outer diameter of the first connecting stud is also larger than that of the second connecting stud.

[0011] Advantages of adopting the above - mentioned technical solution: By respectively arranging the first connecting stud and the second connecting stud on the two limiting blocks to achieve positioning connection with the PCB board, the welding positions of the horizontal support feet and the horizontal welding feet are more accurate. Moreover, the heads of the first connecting stud and the second connecting stud are both conical, which can quickly be inserted into the connecting holes on the PCB board by means of the conical heads. Also, the outer diameter of the first connecting stud is set to be larger than that of the second connecting stud, thus achieving the anti - misoperation function.

[0012] Further, strip - shaped guiding columns are arranged on the width sides of the vertical plate. The top of the guiding column protrudes with a tapered head, and the column body of the tapered head gradually shrinks upward.

[0013] Advantages of adopting the above - mentioned technical solution: The arrangement of the guiding columns realizes the stable assembly of the seat body and the external shell. The arrangement of the tapered head makes the installation more convenient and smoother, and the structural design is reasonable.

[0014] Further, a first insertion hole is vertically penetrated through the vertical plate. The first insertion hole corresponds to the terminal and is used for the terminal to pass through and be fixed. A second insertion hole is formed at the bottom of the transverse plate corresponding to the support member.

[0015] Advantages of adopting the above - mentioned technical solution: The terminal is connected to the vertical plate through cooperation with the first insertion hole, and the support member is connected to the transverse plate through cooperation with the second insertion hole. The assembly structure is simple, has high reliability, is convenient for assembly and maintenance, and has strong applicability.

[0016] Further, the upper end of the terminal is horizontally bent backward to form a horizontal insertion section. Corresponding spaced columns are also protruded at the upper end of the vertical plate, and adjacent spaced columns are arranged on both sides of the horizontal insertion section.

[0017] Advantages of adopting the above technical solution: The upper end of the terminal is set as a horizontally inserted section bent reversely horizontally, making the space occupied by the connector more reasonable.

Detailed Embodiment

[0023] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model and / or the prior art, the specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained. Additionally, the terms related to orientation only represent the relative positional relationship between components, rather than the absolute positional relationship.

[0024] Please refer to Figures 1 to 4As shown, a connector terminal seat includes a seat body 1 and a plurality of terminals 2. The seat body 1 includes a vertical plate 3 and a horizontal plate 4. The horizontal plate 4 is connected to the left side or right side of the vertical plate 3. The terminals 2 are arranged side by side on the vertical plate 3 and the lower ends are horizontally bent outward to form horizontal welding legs 5. More specifically, the horizontal welding legs 5 are bent along the side away from the horizontal plate 4. At least two support members 6 are connected to the far end of the bottom of the horizontal plate 4. The support members 6 are arranged side by side with a front-to-back spacing. The support members 6 are made of metal material, and the lower ends are horizontally bent in the opposite direction relative to the horizontal welding legs 5 to form horizontal support legs 7. , and the bottom of the horizontal supporting foot 7 and the horizontal welding foot 5 are located at the same height. By setting a supporting member 6 made of metal material, the horizontal supporting foot 7 of the supporting member 6 can be welded to the PCB board through a welding process. After welding, the horizontal supporting foot 7 forms an auxiliary support for the horizontal welding foot 5 after welding with the PCB board, so that the connection between the horizontal welding foot 5 and the PCB board is highly stable. Therefore, after the terminal block is connected to the PCB board, the connection is stable and the force is more uniform. It is not easy to deviate from the position during use, which can effectively ensure the service life of the PCB board, and the overall structural design is reasonable.

[0025] In this embodiment, a support block 8 is further provided at the connection between the bottom of the transverse plate 4 and the corresponding support member 6. By providing the support block 8, the support member 6 can be more stably connected to the transverse plate 4, and the use effect is better. The bottom of the support block 8 is flush with the bottom of the vertical plate 3, that is, the bottom of the transverse plate 4 will be higher than the bottom of the vertical plate 3.

[0026] In this embodiment, limit blocks 9 are provided at intervals in front and back of the bottom of the transverse plate 4. The limit blocks 9 are arranged on the inner side of the support block 8. The limit blocks 9 are used to limit excessive deformation of the horizontal supporting legs 7 and the horizontal welding legs 5. In the above structure, the limit blocks 9 can effectively prevent the horizontal supporting legs 7 and the horizontal welding legs 5 from being excessively stressed and deformed, thereby ensuring the safety of use and a reasonable structural design. Since the bottom of the transverse plate 4 will be higher than the bottom of the vertical plate 3, the setting of the limit blocks 9 will not cause the horizontal supporting legs 7 and the horizontal welding legs 5 to be too far away from the bottom surface of the seat body 1.

[0027] In this embodiment, the limiting blocks 9 are arranged side by side. More specifically, the limiting blocks 9 are arranged in the middle of the bottom surface length of the seat body 1. At the bottom of the limiting blocks 9, a first connecting plug post 10 and a second connecting plug post 11 are respectively provided. The heads of the first connecting plug post 10 and the second connecting plug post 11 are both conical, and the outer diameter of the first connecting plug post 10 is larger than that of the second connecting plug post 11. By respectively arranging the first connecting plug post 10 and the second connecting plug post 11 on the two limiting blocks 9, the positioning connection with the PCB board is realized, so that the welding positions of the horizontal support feet 7 and the horizontal welding feet 5 are more accurate. Moreover, the heads of the first connecting plug post 10 and the second connecting plug post 11 are both conical, which can quickly snap into the connecting holes on the PCB board by means of the conical heads. The outer diameter of the first connecting plug post 10 is set to be larger than that of the second connecting plug post 11, thus realizing the anti-fooling function.

[0028] In this embodiment, strip-shaped guiding columns 12 are provided on the width sides of the vertical plates 3. A tapered head 13 protrudes from the top of the guiding column 12, and the column body of the tapered head 13 gradually shrinks upward. The arrangement of the guiding columns 12 realizes the stable assembly of the seat body 1 and the external housing. The setting of the tapered head 13 makes the installation more convenient and smoother, and the structural design is reasonable.

[0029] In this embodiment, a first insertion hole 14 is vertically penetrated through the vertical plate 3. The first insertion hole 14 corresponds to the terminal 2 for the terminal 2 to be inserted and fixed. A second insertion hole 15 is formed at the bottom of the horizontal plate 4 corresponding to the support member 6. The terminal 2 is connected to the vertical plate 3 through the cooperation with the first insertion hole 14, and the support member 6 is connected to the horizontal plate 4 through the cooperation with the second insertion hole 15. The assembly structure is simple, has high reliability, is convenient for assembly and maintenance, and has strong applicability.

[0030] In this embodiment, the upper end of the terminal 2 is horizontally bent reversely to form a horizontal insertion section 16. A corresponding spacer post 17 also protrudes from the upper end of the vertical plate 3. The adjacent spacer posts 17 are arranged on both sides of the horizontal insertion section 16 relative to each other. Setting the upper end of the terminal 2 as the horizontally bent reverse horizontal insertion section 16 makes the space occupied by the connector more reasonable. The setting of the spacer posts 17 can make the horizontal insertion section 16 remain relatively parallel after being bent, thus avoiding the phenomenon of skewed contact and being safer to use.
