Technical Field

[0001] This utility model relates to the field of electronic device technology, and in particular to a novel connector. Background Technology

[0002] Pin headers and sockets are types of electronic connectors, typically used in pairs. Pin headers are assemblies with multiple metal pins, while sockets are their corresponding assemblies with multiple sockets. They achieve a reliable connection to the circuit board through the mating of the pins and sockets. Pin headers and sockets act as bridges between interrupted or isolated circuits, facilitating the transmission of current or signals. They are widely used in various electronic devices.

[0003] In existing technologies, in some application scenarios, to ensure better alignment of the metal pins of the female connector with the PCB board and to ensure a stable connection, a metal structure for alignment is added to the pins of the female connector that mate with the PCB board. This metal structure is only used for alignment, but it requires separate stamping, electroplating, and assembly with the plastic housing. This increases material usage, and the forming and assembly process is cumbersome and costly. Furthermore, these special metal structures generally require manual assembly, which is prone to deformation, preventing the product from being properly positioned on the board. Manual assembly also increases assembly time.

[0034] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please see Figures 1 to 3 This utility model provides a novel connector 100, including a terminal assembly 30, a plastic base 10, and a plastic housing 20. The terminal assembly 30 includes a plurality of terminal pieces 31 for electrical connection. The plastic base 10 includes a seat 11, on which a plurality of mounting cavities 14 for mounting the terminal pieces 31 are formed. One end of each terminal piece 31 is mounted within a mounting cavity 14 and protrudes beyond the seat 11 to mate with a PCB board. Positioning posts 12 are provided protruding along the thickness direction of the seat 11 on its side for positioning on the PCB board. The positioning posts 12 and the seat 11 are integrally formed, resulting in a more stable and easier-to-mold structure. The plastic housing 20 has a hollow receiving cavity 201, which is engaged with the plastic base 10 to cover the terminal assembly 30. The plastic housing 20 has multiple fixing cavities 22 at the end away from the plastic base 10, and the terminal piece 31 is installed in one of the fixing cavities 22 at the end away from the plastic base 10. It is understood that the terminal piece 31 includes a first connecting end 311 and a second connecting end 312. The first connecting end 311 is located within the mounting cavity 14 of the plastic base 10 and is used for connection to the PCB board. The second connecting end 312 is located within the fixing cavity 22 of the plastic housing 20 and is used for connection to other connectors. The terminal piece 31 passes through the end of the plastic housing 20 where the fixing cavity 22 is located, and then that end is installed within the plastic base 10. Guide portions are provided on the surfaces of the fixing cavity 22 and the mounting cavity 14 for the terminal piece 31 to pass through.

[0036] Compared with the prior art, the novel connector 100 of this utility model includes a terminal assembly 30, a plastic base 10, and a plastic housing 20. The terminal assembly 30 is installed within the plastic base 10 and the plastic housing 20. The terminal assembly 30 includes a plurality of terminal pieces 31. The plastic base 10 includes a seat 11, and a plurality of mounting cavities 14 for mounting the terminal pieces 31 are formed through the seat 11. The plastic housing 20 is provided with a hollow receiving cavity 201, and the plastic housing 20 is engaged with the plastic base 10 so that the receiving cavity 201 covers the terminal assembly 30. A plurality of fixing cavities 22 are formed at the end of the plastic housing 20 away from the plastic base 10, and the end of the terminal piece 31 away from the plastic base 10 is installed in the fixing cavity 22. Among them, a positioning post 12 for positioning is provided on the side of the seat 11 along the thickness direction of the seat 11, and the positioning post 12 is integrally formed with the seat 11. The positioning post 12 can mate with the PCB board for positioning, making the installation more stable and the overall structure more robust. The positioning post 12 and the base 11 are integrally molded, which not only makes molding easier and lowers costs but also reduces deformation and provides good positioning performance. This novel connector 100 of the present invention offers easier molding, lower costs, and better positioning performance.

[0037] Please see Figure 4 and Figure 5 In some optional embodiments, the positioning post 12 includes a first positioning block 121, a second positioning block 122, and a connecting portion 120. The first positioning block 121 and the second positioning block 122 are connected to the base 11 via the connecting portion 120. A movable space 123 is provided between the first positioning block 121 and the second positioning block 122, allowing them to move elastically relative to each other. It is understood that both the first positioning block 121 and the second positioning block 122 can move elastically within a certain range. When the first positioning block 121 and the second positioning block 122 are installed in the mounting holes of the PCB board, a slight elastic compression of the first positioning block 121 and the second positioning block 122 allows them to move elastically within a certain range through the movable space 123, resulting in a more stable fit between the first positioning block 121 and the second positioning block 122 and the mounting holes on the PCB board, leading to a better installation effect.

[0038] Please see Figure 4 and Figure 5In some optional embodiments, the ends of the first positioning block 121 and the second positioning block 122 away from the plastic base 10 both have a gradually decreasing cross-sectional area to form a guide portion 125 for easy installation. It is understood that, to facilitate the installation of the first positioning block 121 and the second positioning block 122 into the mounting holes of the PCB board, the ends of the first positioning block 121 and the second positioning block 122 that are in contact with the PCB board are provided with guide portions 125 to guide the first positioning block 121 and the second positioning block 122 to be installed more conveniently into the mounting holes.

[0039] Please see Figure 4 and Figure 5 In some optional embodiments, a limiting block 124 is provided on the first positioning block 121 or the second positioning block 122, and a limiting groove is formed in the mounting hole on the PCB board. The limiting block 124 cooperates with the limiting groove to strengthen the assembly of the positioning post 12 and the PCB board. In this embodiment, positioning posts 12 are provided on both sides of the plastic base 10, and the positioning posts 12 on both sides of the plastic base 10 can be symmetrically arranged. Among the positioning posts 12, the first positioning block 121 is located on the outer side, and the second positioning block 122 is located on the inner side. The limiting block 124 can be set on the first positioning block 121 so that the first positioning block 121 is pressed from the outside, so that the limiting block 124 disengages from the limiting groove to release the plastic base 10 on the PCB board, thereby releasing the entire novel connector 100. It can be understood that the first positioning block 121 and the second positioning block 122 are installed in the mounting hole of the PCB board, and the limiting block 124 is engaged in the limiting groove in the mounting hole to make the overall structure stable and reliable. When the new connector 100 needs to be disassembled, the first positioning block 121 on the outer side is pressed elastically, causing the limiting block 124 to disengage from the limiting groove, thereby allowing the new connector 100 to be disassembled from the PCB board. The structure of the first positioning block 121 and the second positioning block 122 makes the installation and disassembly of the new connector 100 more convenient, and the connection is stable, with a stable overall structure.

[0040] Please see Figure 4 and Figure 5 In some optional embodiments, the positioning post 12 is L-shaped and includes a connecting portion 120. The connecting portion 120 forms an L-shape with the first positioning block 121 and the second positioning block 122. The connecting portion 120 is connected to the base 11. The first positioning block 121 and the second positioning block 122 are both disposed on the connecting portion 120 and are approximately perpendicular to the connecting portion 120, so that the first positioning block 121 and the second positioning block 122 can be well positioned and engaged with the PCB board.

[0041] Please see Figures 1 to 5In some optional embodiments, at least one positioning post 12 is provided on one or both sides of the base 11. That is, at least one positioning post 12 can be provided on one side of the base 11, or positioning posts 12 can be provided on both sides of the base 11, with at least one positioning post 12 on each side. The number of positioning posts 12 on both sides can be the same or different. In addition, positioning posts 12 can also be provided on the surface of the base 11 that mates with the PCB board. As long as the positioning posts 12 can reinforce the mating between the base 11 and the PCB board, it is acceptable. In this embodiment, the positioning posts 12 are provided on both sides of the base 11 to facilitate installation and disassembly operations.

[0042] Please see Figures 1 to 6 In some optional embodiments, the plastic base 10 is provided with a first engaging portion 13, and the plastic housing 20 is provided with a second engaging portion 21. The second engaging portion 21 engages with the first engaging portion 13 to secure the plastic housing 20 onto the plastic base 10. The plastic base 10 and the plastic housing 20 are securely connected by the first engaging portion 13 and the second engaging portion 21, resulting in a stable connection. A plurality of ribs 23 are protruding within the plastic housing 20, forming a positioning space 24 between two ribs 23. This positioning space 24 allows for better positioning and isolation of adjacent end pieces 31.

[0043] Please see Figure 7 and Figure 8 In some optional embodiments, the end of the terminal piece 31 extending out of the plastic base 10 is a first connecting end 311, used for electrical connection with the PCB board. The end of the terminal piece 31 located within the fixing cavity 22 is a second connecting end 312, used for electrical connection with other connectors. The first connecting end 311 has a groove formed thereon, which is a positioning groove 3111. The positioning groove 3111 can mate with the PCB board to better position and connect the first connecting end 311 and the PCB board.

[0044] like Figures 1 to 8As shown, the novel connector 100 of this utility model includes a terminal assembly 30, a plastic base 10, and a plastic housing 20. The terminal assembly 30 is installed within the plastic base 10 and the plastic housing 20. The terminal assembly 30 includes multiple terminal pieces 31. The plastic base 10 includes a seat 11, and multiple mounting cavities 14 for mounting the terminal pieces 31 are formed through the seat 11. The plastic housing 20 is provided with a hollow receiving cavity 201, and the plastic housing 20 is engaged with the plastic base 10 so that the receiving cavity 201 covers the terminal assembly 30. Multiple fixing cavities 22 are formed at the end of the plastic housing 20 away from the plastic base 10, and the end of the terminal piece 31 away from the plastic base 10 is installed in the fixing cavity 22. A positioning post 12 for positioning is provided protruding along the thickness direction of the seat 11 on the side of the seat 11, and the positioning post 12 is integrally formed with the seat 11. The positioning post 12 can cooperate with the PCB board for positioning, making the installation more stable and the overall structure more robust. The positioning post 12 and the base 11 are integrally formed, which not only makes the forming easier and lowers the cost, but also makes it less prone to deformation and provides a good positioning effect. The positioning post 12 includes a first positioning block 121 and a second positioning block 122 that can move elastically relative to each other. The first positioning block 121 is provided with a limit block 124, which makes the overall installation and disassembly easier and the connection more stable. Previously, similar connectors were installed on the plastic base 10 together with the terminal piece 31 using a metal structure of other shapes for positioning. The metal structure needed to be stamped and electroplated separately before being assembled with the plastic base 10, which increased the materials and made the forming and assembly process cumbersome and costly. Moreover, the special metal structure generally requires manual assembly, but manual assembly is prone to deformation, which can prevent the product from being positioned on the board, resulting in inconvenient installation and increased assembly time. The new connector 100 of this utility model is easier to form, lower in cost, and provides a better positioning and installation effect.

[0045] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
