Abstract
Description
Technical Field
[0001] This application belongs to the technical field of electrical connection devices, and specifically relates to a connector for a feeder terminal. Background Technology
[0002] A feeder terminal is an intelligent terminal device installed in a power distribution room or on a feeder line. It integrates functions such as telemetry, remote signaling, remote control, protection, and communication, and has the advantage of small size. Connectors are an important component of the feeder terminal, mainly used to connect the feeder terminal to other hardware in the power distribution network. Because feeder terminals have requirements for signal acquisition, power supply, communication, and control output, the connectors used for feeder terminals need to have multiple pins to meet the various needs of the feeder terminal through a single connector.
[0003] Currently, connectors for feeder terminals typically include an insulator, a circuit board, and multiple pins located on the insulator. These pins are usually electrically connected to the circuit board via wires. Due to the large number of pins and the small size of the connector, the connection points between the wires and the circuit board are densely distributed, which affects the voltage withstand performance of the circuit board. Furthermore, the limited internal space of the connector increases the difficulty of assembling the connector.
[0004] To improve the voltage withstand performance of the circuit board, some connectors are equipped with two spaced-apart circuit boards, and some pins are designed to be extended. The extended pins are connected to the circuit board away from the insulator, while the pins without extension are connected to the circuit board closer to the insulator. Although this reduces the density of pin-to-circuit board connection points and improves the voltage withstand performance of the circuit board, it increases the production cost of the connector because it requires two circuit boards. Utility Model Content
[0005] This application provides a connector for feeder terminations to reduce the production cost of the connector while ensuring the voltage withstand performance of the circuit board.
[0006] The technical solution adopted in this application is as follows:
[0007] A connector for a feeder terminal includes an insulator, a circuit board, a plurality of first pins, and a plurality of second pins. The insulator has a mating end face, and the circuit board is located on the side of the insulator opposite to the mating end face. The insulator has a central region and an edge region surrounding the central region. Each first pin has a first mating segment located in the central region and a first connecting segment connected to the circuit board. The projection of the first connecting segment toward the mating end face is located inside the first mating segment. Each second pin has a second mating segment located in the edge region and a second connecting segment connected to the circuit board. The projection of the second connecting segment toward the mating end face is at least partially located outside the second mating segment and on the side of the second mating segment opposite to the first mating segment.
[0008] By adopting the above technical solution, since the first plug segment is located in the central area, the first pin is located in the central area of the insulator, and since the second plug segment is located in the edge area, the second pin is located in the edge area. This allows the first pin and the second pin to be placed at different positions on the insulator, thereby reducing the distribution density of the first pin and the second pin on the insulator, and further reducing the distribution density of the first pin and the second pin at the connection position with the circuit board.
[0009] Furthermore, since the projection of the first connecting segment toward the plug-in end face is located inside the first plug-in segment, and the projection of the second connecting segment toward the plug-in end face is at least partially located outside the second plug-in segment and on the side of the second plug-in segment away from the first plug-in segment, the distance between the second connecting segment and the first connecting segment is increased. This allows the connection position of the second connecting segment and the circuit board to be located at the edge of the insulator, thereby increasing the distance between the connection positions of the first connecting segment and the circuit board and the connection positions of the second connecting segment and the circuit board. This reduces the distribution density of the connection positions of the first connecting segment and the second connecting segment with the circuit board, thereby improving the voltage withstand performance of the circuit board, ensuring the service life of the connector, and improving the user experience.
[0010] Furthermore, compared to the prior art where pins are connected to the circuit board via wires, the connector in this application not only reduces the distribution density of the pin-to-circuit board connection points but also reduces the assembly difficulty of the connector, thereby improving the production efficiency of the connector. Compared to the prior art connector with two circuit boards, the number of circuit boards is reduced, thereby reducing the production cost of the connector.
[0011] Optionally, the second connecting segment extends at an angle away from the central area from the second plug-in segment in the direction of the circuit board.
[0012] By adopting the above technical solution, since the second connecting segment extends at an angle away from the central area from the second plug-in segment to the circuit board, on the one hand, the projection of the second connecting segment toward the plug-in end face is at least partially located outside the second plug-in segment, and on the other hand, the production difficulty of the second pin is reduced.
[0013] Optionally, the second connecting segment includes a bent portion connected to the second plug-in segment and a straight portion connected to the bent portion, the straight portion being connected to the circuit board and arranged parallel to the first connecting segment.
[0014] By adopting the above technical solution, since the second connecting segment includes a curved part and a straight part, and the straight part is connected to the circuit board and is arranged parallel to the first connecting segment, on the one hand, the projection of the second connecting segment toward the plug-in end face is at least partially located outside the second plug-in segment, and on the other hand, the connection difficulty between the second connecting segment and the circuit board is reduced, thereby improving the production efficiency of the connector.
[0015] Optionally, the insulator has a receiving groove on the side opposite to the plug end face, and the bent portion is located in the receiving groove.
[0016] By adopting the above technical solution, since the bent part is located in the receiving groove, the second pin can be positioned and limited by the receiving groove to increase the stability of the second pin. On the other hand, the bent part can be hidden inside the insulator so that the circuit board can abut against the end face of the insulator away from the plug end face to increase the stability of the circuit board. Furthermore, the amount of raw materials required for the insulator during production can be reduced to reduce the manufacturing cost of the insulator, thereby reducing the production cost of the connector.
[0017] Optionally, the circuit board is provided with a first connection hole and a second connection hole. The first connection hole is provided in a one-to-one correspondence with the first connection segment, and each first connection segment passes through its corresponding first connection hole. The second connection hole is provided in a one-to-one correspondence with the second connection segment, and each second connection segment passes through its corresponding second connection hole.
[0018] By adopting the above technical solution, since each first connecting segment is inserted through its corresponding first connecting hole and each second connecting segment is inserted through its corresponding second connecting hole, the connection stability between the first connecting segment and the second connecting segment and the circuit board is increased on the one hand, and the circuit board can be positioned by the first connecting segment and the second connecting segment to increase the stability of the circuit board on the other hand.
[0019] Optionally, the second connecting segment is inclined, and the central axis of the second connecting hole is parallel to the inclined direction of the second connecting segment.
[0020] By adopting the above technical solution, since the second connecting segment is inclined and the central axis of the second connecting hole is parallel to the inclined direction of the second connecting segment, on the one hand, it can reduce the difficulty of the second connecting segment passing through the second connecting hole, thereby reducing the production difficulty of the connector and improving the production efficiency of the connector; on the other hand, it can also use the cooperation of multiple second connecting segments with the hole wall of the second connecting hole to achieve the limiting of the circuit board, thereby further increasing the stability of the circuit board.
[0021] Optionally, the second connection segment includes a blocking portion located on the side of the circuit board away from the insulator, and the blocking portion extends parallel to the direction from the center area to the edge area.
[0022] By adopting the above technical solution, since the blocking part is located on the side of the circuit board away from the insulator and extends parallel to the direction from the center area to the edge area, the blocking part can block the circuit board to further increase the stability of the circuit board. At the same time, it can also increase the connection area between the second connecting section and the circuit board to increase the electrical connection stability between the second connecting section and the circuit board.
[0023] Optionally, the circuit board is provided with positioning holes, and the insulator is provided with positioning posts, the positioning posts being able to extend into the positioning holes.
[0024] By adopting the above technical solution, since the positioning post can extend into the positioning hole, after the circuit board is installed on the insulator, the circuit board can be positioned by the insertion and cooperation of the positioning post and the positioning hole, so as to further increase the stability of the circuit board. At the same time, it avoids the possibility that the circuit board may shake relative to the insulator, which would affect the electrical connection stability between the circuit board and the first connecting segment and the second connecting segment, so as to ensure the electrical connection stability between the first connecting segment and the second connecting segment and the circuit board.
[0025] Optionally, the length of the positioning post passing through the positioning hole is greater than the length of the first connecting segment passing through the circuit board and greater than the length of the second connecting segment passing through the circuit board.
[0026] By adopting the above technical solution, since the length of the positioning post passing through the positioning hole is greater than the length of the first connecting segment passing through the circuit board and greater than the length of the second connecting segment passing through the circuit board, the positioning post is inserted into the circuit board before the first and second connecting segments when installing the circuit board. This allows the circuit board to be positioned by the insertion and cooperation of the positioning post and the positioning hole, thereby reducing the difficulty of installing the circuit board and improving the production efficiency of the connector.
[0027] Optionally, the first plug segment is provided with a stop portion, the stop portion being located on the side of the plug end face close to the circuit board, and the stop portion being able to cooperate with the insulator stop in the direction close to the plug end face.
[0028] By adopting the above technical solution, since the stop part can cooperate with the insulator stop in the direction close to the plug end face, the stop part can block the first pin when the connector is separated from the plug, so as to prevent the pin from separating from the insulator under the action of the plug, thereby increasing the connection stability between the first pin and the insulator; at the same time, the stop part can also limit the depth of the first pin inserted into the insulator, thereby reducing the installation difficulty of the first pin, and further improving the production efficiency of the connector.
[0029] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0030] 1. The connector in this application includes an insulator, a circuit board, a plurality of first pins, and a plurality of second pins. The insulator has a mating end face, and the circuit board is located on the side of the insulator opposite to the mating end face. The insulator has a central region and an edge region surrounding the central region. Each first pin has a first mating segment located in the central region and a first connecting segment connected to the circuit board. The projection of the first connecting segment toward the mating end face is located inside the first mating segment. Each second pin has a second mating segment located in the edge region and a second connecting segment connected to the circuit board. The projection of the second connecting segment toward the mating end face is at least partially located outside the second mating segment and on the side of the second mating segment opposite to the first mating segment. This increases the distance between the second mating segment and the first mating segment, allowing the connection position of the second connecting segment and the circuit board to be located at the edge of the insulator. This increases the distance between the connection positions of the first connecting segment and the circuit board and the connection positions of the second connecting segment and the circuit board, thereby reducing the distribution density of the connection positions of the first and second connecting segments with the circuit board. This improves the voltage withstand performance of the circuit board, ensuring the service life of the connector and improving the user experience.
[0031] 2. In this application, the second connecting segment extends at an angle away from the central area from the direction of the second plug-in segment to the circuit board. This achieves, on the one hand, that the projection of the second connecting segment toward the plug-in end face is at least partially located outside the second plug-in segment, and on the other hand, reduces the manufacturing difficulty of the second pin.
[0032] 3. The second connecting segment in this application includes a bent portion connected to the second plug-in segment and a straight portion connected to the bent portion. The straight portion is connected to the circuit board and is arranged parallel to the first connecting segment. This achieves, on the one hand, that the projection of the second connecting segment toward the plug-in end face is at least partially located outside the second plug-in segment, and on the other hand, reduces the difficulty of connecting the second connecting segment to the circuit board, thereby improving the production efficiency of the connector.

[0047] Reference Figures 1 to 6A connector for a feeder terminal is disclosed, comprising an insulator 1, a circuit board 2, a plurality of first pins 3 and a plurality of second pins 4. The insulator 1 has a mating end face, and the circuit board 2 is located on the side of the insulator 1 opposite to the mating end face. The insulator 1 has a central region 11 and an edge region 12 surrounding the central region 11. Each first pin 3 has a first mating segment 31 disposed in the central region 11 and a first connecting segment 32 connected to the circuit board 2. The projection of the first connecting segment 32 toward the mating end face is located inside the first mating segment 31. Each second pin 4 has a second mating segment 41 disposed in the edge region 12 and a second connecting segment 42 connected to the circuit board 2. The projection of the second connecting segment 42 toward the mating end face is at least partially located outside the second mating segment 41 and on the side of the second mating segment 41 opposite to the first mating segment 31.
[0048] It is understood that multiple first pins 3 are located in the central area 11 and are spaced apart circumferentially along the central area 11, and multiple second pins 4 are located in the edge area 12 and are spaced apart circumferentially along the edge area 12. The first connecting segment 32 is fixedly connected to the circuit board 2 by soldering, and the second connecting segment 42 is connected to the circuit board 2 by soldering.
[0049] Since the first plug segment 31 is located in the central region 11, the first pin 3 is located in the central region 11 of the insulator 1. Since the second plug segment 41 is located in the edge region 12, the second pin 4 is located in the edge region 12. This allows the first pin 3 and the second pin 4 to be located at different positions on the insulator 1, thereby reducing the distribution density of the first pin 3 and the second pin 4 on the insulator 1 and further reducing the distribution density of the first pin 3 and the second pin 4 at the connection positions with the circuit board 2.
[0050] Furthermore, since the projection of the first connecting segment 32 toward the plug-in end face is located inside the first plug-in segment 31, and the projection of the second connecting segment 42 toward the plug-in end face is at least partially located outside the second plug-in segment 41 and on the side of the second plug-in segment 41 away from the first plug-in segment 31, the distance between the second connecting segment 42 and the first connecting segment 32 is increased. This allows the connection position of the second connecting segment 42 and the circuit board 2 to be located at the edge of the insulator 1, thereby increasing the distance between the connection positions of the first connecting segment 32 and the circuit board 2 and the connection positions of the second connecting segment 42 and the circuit board 2. This reduces the distribution density of the connection positions of the first connecting segment 32 and the second connecting segment 42 with the circuit board 2, thereby improving the voltage withstand performance of the circuit board 2, ensuring the service life of the connector, and improving the user experience.
[0051] Furthermore, compared to the prior art where pins are connected to circuit board 2 via wires, the connector in this application not only reduces the distribution density of the connection points between the pins and circuit board 2, but also reduces the assembly difficulty of the connector, thereby improving the production efficiency of the connector; compared to the prior art connector with two circuit boards 2, the number of circuit boards 2 is reduced, thereby reducing the production cost of the connector.
[0052] Specifically, the insulator 1 is provided with a plurality of first mounting holes 111 and a plurality of second mounting holes 121 extending through its own axial direction. The first mounting holes 111 are provided one-to-one with the first pins 3. The first insertion segment 31 of each first pin 3 is inserted into its corresponding first mounting hole 111 and is press-fitted with the hole wall of the first mounting hole 111. The second mounting holes 121 are provided one-to-one with the second pins 4. The second insertion segment 41 of each second pin 4 is inserted into its corresponding second mounting hole 121 and is press-fitted with the hole wall of the second mounting hole 121.
[0053] The better one is to refer to Figure 3 The axis of the first mounting hole 111 and the axis of the second mounting hole 121 are both parallel to the axis of the insulator 1, so as to facilitate the insertion and mating of the connector with the external plug.
[0054] This application does not specify the number of the first pin 3 and the second pin 4. Preferably, refer to Figures 1 to 4 The connector has four first pins 3 and ten second pins 4 to meet the requirements of the feeder terminal. In other embodiments, the number of first pins 3 and second pins 4 can be other than 14, as long as their sum equals 14.
[0055] This application does not specifically limit the extension direction of the first connecting segment 32; preferably, refer to... Figure 2 and Figure 5 The first connecting segment 32 extends parallel to the axial direction of the first insertion segment 31, and the first connecting segment 32 and the first insertion segment 31 are coaxially arranged to reduce the manufacturing difficulty of the first pin 3. In other embodiments, the extending direction of the first connecting segment 32 may also be at an angle to the axial direction of the first insertion segment 31, for example, at an angle of 1° or 1.5°, as long as the projection of the insertion end face of the first connecting segment 32 is located inside the first insertion segment 31.
[0056] This application does not specifically limit the formation of the second connecting segment 42 with its projection toward the insertion end face at least partially located outside the second insertion segment 41, and it can adopt any of the following embodiments:
[0057] In this embodiment, the second connecting segment 42 extends obliquely from the direction of the second plug-in segment 41 to the circuit board 2 toward the direction away from the central area 11.
[0058] It is understandable that the extension direction of the second connecting segment 42 is set at an angle to the axis of the second plug-in segment 41.
[0059] Since the second connecting segment 42 is inclined and extends from the second plug segment 41 to the circuit board 2 in a direction away from the central area 11, on the one hand, the projection of the second connecting segment 42 toward the plug end face is at least partially located outside the second plug segment 41, and on the other hand, the production difficulty of the second pin 4 is reduced.
[0060] Implementation Method Two: In this implementation method, refer to... Figure 2 , Figure 3 and Figure 6 The second connecting segment 42 includes a bent portion 421 connected to the second plug-in segment 41 and a straight portion 422 connected to the bent portion 421. The straight portion 422 is connected to the circuit board 2 and is arranged parallel to the first connecting segment 32.
[0061] It is understood that the curved portion 421 is located on the side of the second insertion segment 41 away from the central area 11, so that the straight portion 422 is located on the side of the second insertion segment 41 away from the central area 11.
[0062] Since the second connecting segment 42 includes a bent portion 421 and a straight portion 422, and the straight portion 422 is connected to the circuit board 2 and is arranged parallel to the first connecting segment 32, on the one hand, the projection of the second connecting segment 42 toward the plug-in end face is at least partially located outside the second plug-in segment 41, and on the other hand, the connection difficulty between the second connecting segment 42 and the circuit board 2 is reduced, thereby improving the production efficiency of the connector.
[0063] This application does not specifically limit the structure of the curved portion 421 and the straight portion 422. Preferably, refer to Figure 2 and Figure 3 Both the curved portion 421 and the straight portion 422 are cylindrical structures with circular cross-sections to ensure the structural strength of the second connecting segment 42. In other embodiments, both the curved portion 421 and the straight portion 422 may also be sheet-like structures.
[0064] Furthermore, refer to Figure 2 and Figure 3 An accommodating groove 122 is provided on the side of the insulator 1 away from the plug end face, and the bent part 421 is located in the accommodating groove 122.
[0065] Understandably, after the second pin 4 is installed on the insulator 1, the bent section is hidden in the receiving groove 122.
[0066] Since the bent portion 421 is located in the receiving groove 122, the receiving groove 122 can be used to position and limit the second pin 4 to increase the stability of the second pin 4. On the other hand, the bent portion 421 can be hidden inside the insulator 1 so that the circuit board 2 can abut against the end face of the insulator 1 away from the plug end face to increase the stability of the circuit board 2. Furthermore, the amount of raw materials required for the insulator 1 during production can be reduced to reduce the manufacturing cost of the insulator 1, thereby reducing the production cost of the connector.
[0067] In a preferred embodiment, refer to Figure 2 The circuit board 2 is provided with a first connection hole 21 and a second connection hole 22. The first connection hole 21 is provided in a one-to-one correspondence with the first connection segment 32, and each first connection segment 32 passes through its corresponding first connection hole 21. The second connection hole 22 is provided in a one-to-one correspondence with the second connection segment 42, and each second connection segment 42 passes through its corresponding second connection hole 22.
[0068] Since each first connecting segment 32 is inserted through its corresponding first connecting hole 21 and each second connecting segment 42 is inserted through its corresponding second connecting hole 22, the connection stability between the first connecting segment 32, the second connecting segment 42 and the circuit board 2 is increased on the one hand, and the first connecting segment 32 and the second connecting segment 42 can be used to position the circuit board 2 to increase the stability of the circuit board 2 on the other hand.
[0069] Furthermore, the second connecting segment 42 is inclined, and the central axis of the second connecting hole 22 is parallel to the inclined direction of the second connecting segment 42. This reduces the difficulty of the second connecting segment 42 passing through the second connecting hole 22, thereby reducing the production difficulty of the connector and improving the production efficiency of the connector. On the other hand, it can also use the cooperation of multiple second connecting segments 42 with the hole wall of the second connecting hole 22 to limit the circuit board 2, thereby further increasing the stability of the circuit board 2.
[0070] It should be noted that when the second connecting segment 42 is inclined and the central axis of the second connecting hole 22 is parallel to the inclined direction of the second connecting segment 42, the second connecting segment 42 needs to be inserted into the circuit board 2 first, and then the insulator 1 is installed on the circuit board 2 so that the second plug segment 41 is inserted into the insulator 1.
[0071] Furthermore, the second connection segment 42 includes a blocking portion located on the side of the circuit board 2 away from the insulator 1, and the blocking portion extends parallel to the direction from the center region 11 to the edge region 12.
[0072] It is understandable that the blocking part is formed by the partial bending of the second connecting section 42 through the second connecting hole 22.
[0073] Since the blocking part is located on the side of the circuit board 2 away from the insulator 1, and the blocking part extends parallel to the direction from the center area 11 to the edge area 12, the blocking part can block the circuit board 2 to further increase the stability of the circuit board 2. At the same time, it can also increase the connection area between the second connecting section 42 and the circuit board 2 to increase the electrical connection stability between the second connecting section 42 and the circuit board 2.
[0074] This application does not specifically limit the structure of the blocking part. When the cross-section of the curved part 421 and the straight part 422 is circular, the blocking part is also circular; when the curved part 421 and the straight part 422 are sheet-like structures, the blocking part is also sheet-like.
[0075] In a preferred embodiment, refer to Figure 2 and Figure 3 The circuit board 2 is provided with a positioning hole 23, and the insulator 1 is provided with a positioning post 123, which can extend into the positioning hole 23.
[0076] Understandably, after the circuit board 2 is installed on the insulator 1, the positioning post 123 extends into the positioning hole 23.
[0077] Since the positioning post 123 can extend into the positioning hole 23, after the circuit board 2 is installed on the insulator 1, the circuit board 2 can be positioned by the insertion and cooperation of the positioning post 123 and the positioning hole 23, so as to further increase the stability of the circuit board 2. At the same time, it avoids the possibility that the circuit board 2 may shake relative to the insulator 1, which would affect the electrical connection stability between the circuit board 2 and the first connecting section 32 and the second connecting section 42, so as to ensure the electrical connection stability between the first connecting section 32 and the second connecting section 42 and the circuit board 2.
[0078] This application does not specifically limit the location of the positioning post 123. Preferably, the positioning post 123 is located on the end face of the insulator 1 away from the insertion end face, so as to reduce the volume of the insulator 1. In other embodiments, the positioning post 123 may also be located on the side of the insulator 1.
[0079] Furthermore, the length of the positioning post 123 passing through the positioning hole 23 is greater than the length of the first connecting segment 32 passing through the circuit board 2 and greater than the length of the second connecting segment 42 passing through the circuit board 2. Therefore, when installing the circuit board 2, the positioning post 123 is inserted into the circuit board 2 before the first connecting segment 32 and the second connecting segment 42, so that the circuit board 2 can be positioned by the insertion and cooperation of the positioning post 123 and the positioning hole 23, thereby reducing the installation difficulty of the circuit board 2 and improving the production efficiency of the connector.
[0080] In a preferred embodiment, refer to Figure 2 and Figure 5The first insertion section 31 is provided with a stop 311, which is located on the side of the insertion end face close to the circuit board 2. The stop 311 can cooperate with the insulator 1 in the direction close to the insertion end face. When the connector is separated from the plug, the stop 311 can block the first pin 3 to prevent the pin from separating from the insulator 1 under the action of the plug, thereby increasing the connection stability between the first pin 3 and the insulator 1. At the same time, the stop 311 can also limit the depth of the first pin 3 inserted into the insulator 1 to reduce the installation difficulty of the first pin 3, thereby further improving the production efficiency of the connector.
[0081] Specifically, the first mounting hole 111 is a stepped hole, with the smaller end of the stepped hole located on the side of the insulator 1 away from the circuit board 2, and the larger end of the stepped hole located on the side of the insulator 1 close to the circuit board 2. The stop part 311 abuts against the end wall at the point where the diameter of the stepped hole changes.
[0082] This application does not specifically limit the structure of the stop portion 311; preferably, refer to... Figure 5 The stop portion 311 is an annular structure extending circumferentially along the first insertion segment 31 to increase the stopping and mating area between the stop portion 311 and the insulator 1, thereby further increasing the connection stability between the first pin 3 and the insulator 1. In other embodiments, the stop portion 311 may also be a block structure disposed on the outer peripheral surface of the first insertion segment 31.
