Description

Technical Field

[0001] The present invention relates to the technical field of connector pin sockets, and particularly to a compact connector pin socket. Background Art

[0002] In the design of traditional connector pin sockets, the pin socket with a pin pitch of 4.2 mm (pin distance) has a large size and is difficult to meet the layout requirements of high-density electronic devices; while the existing pin socket with a pin pitch of 3.0 mm saves space, but its height is generally lower than 12.8 mm and it cannot directly be compatible with the device interface designed for the 4.2 mm pin socket. In addition, the redundant insert structures arranged on both sides of the conventional 3.0 mm pin socket further occupy the lateral space, making it difficult to achieve stable replacement and installation in a narrow space. Therefore, it cannot meet the usage requirements. Summary of the Invention

[0003] Aiming at the defects of the above-mentioned existing technologies, the present invention provides a compact connector pin socket, which has a compact structure, small space occupation, is suitable for high-density circuit layout, has stable connection and meets the usage requirements.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A compact connector pin socket includes a pin socket body. There are several pins arranged in the pin socket body. The pins are high-elastic alloy pins. A double-contact elastic piece is arranged at the end of the pin. The double-contact elastic piece is arranged in a stepped shape. The distance between adjacent pins is 3.0 mm, and the height of the pin socket body is 12.7 mm - 12.9 mm.

[0006] Further, the height of the pin socket body is 12.8 mm.

[0007] Further, the pins are gold-plated copper alloy pins.

[0008] Further, a guiding groove is arranged at the top of the housing.

[0009] Further, the depth of the guiding groove is 2.5 mm.

[0010] Further, the pin socket body is integrally formed.

[0011] Further, reinforcing ribs are arranged on both sides of the pin socket body, and the thickness of the reinforcing ribs is 1.2 mm.

[0012] The beneficial effects produced by the present invention are as follows: The pin socket body is provided with a plurality of pins. The pins are high-elastic alloy pins, and the ends of the pins are provided with double-contact elastic pieces. The double-contact elastic pieces are arranged in a stepped shape. The stepped contact layout and the high-elastic alloy pins are adopted to maintain the equivalent current-carrying capacity and signal integrity with the standard pin socket under the compact design; the distance between adjacent pins is 3.0 mm, and the height of the pin socket body is 12.7 mm - 12.9 mm. The pin pitch is reduced from 4.2 mm to 3.0 mm, significantly reducing the lateral space occupation and adapting to the requirements of high-density circuit layout. The overall height of the pin socket is set to 12.7 mm - 12.9 mm, which is the same as the height of the standard 4.2 mm pin pitch pin socket, ensuring that direct replacement can be achieved without modifying the existing device interface; the structure of this product is compact, occupies little space, adapts to high-density circuit layout, has stable connection, and meets the usage requirements.

[0017] To more clearly elaborate the structural features, technical means, and the specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0018] In this embodiment: As Figures 1-3 shown, a compact connector pin socket includes a pin socket body 10. The pin socket body 10 is integrally injection-molded with a high-temperature resistant nylon material. The pin socket body 10 is provided with a plurality of pins 11. The pins 11 are gold-plated copper alloy pins 11. The ends of the pins 11 are provided with double-contact elastic pieces 14. The double-contact elastic piece design is adopted at the ends of the pins 11 to increase the contact pressure and ensure the connection reliability in a high-vibration environment. The double-contact elastic pieces 14 are arranged in a stepped shape. The stepped contact layout and the high-elastic alloy pins 11 are adopted to maintain the equivalent current-carrying capacity and signal integrity with the standard pin socket under the compact design;

[0019] A guiding groove 12 is provided at the top of the housing. The depth of the guiding groove 12 is 2.5 mm, which is convenient for docking with the standard interface;

[0020] The pitch between adjacent pins 11 is 3.0 mm, and the height of the socket body 10 is 12.8 mm. Reducing the pin 11 pitch from 4.2 mm to 3.0 mm significantly reduces the lateral space occupancy and adapts to the requirements of high-density circuit layouts. The overall height of the socket is set at 12.8 mm, which is the same as the height of the socket with a 4.2 mm pin 11 pitch standard, ensuring direct replacement without modifying the existing device interface.

[0021] Reinforcing ribs 13 are provided on both sides of the socket body 10, and the thickness of the reinforcing ribs 13 is 1.2 mm. The unnecessary auxiliary inserts on both sides of the traditional socket are cancelled, further reducing the lateral dimension. The insert installation areas on both sides of the traditional socket are replaced with symmetrically distributed reinforcing ribs 13 to enhance the structural strength and ensure the lateral bending strength, compensating for the mechanical stability after the reduction of the inserts.

[0022] This product improves the structural design of the socket body 10. The pin 11 pitch is reduced from 4.2 mm to 3.0 mm, significantly reducing the lateral space occupancy and adapting to the requirements of high-density circuit layouts; the height of the socket body 10 is increased to 12.8 mm, making it the same as the height of the socket with a 4.2 mm pin 11 pitch standard, ensuring direct replacement without modifying the existing device interface; at the same time, by setting reinforcing ribs 13 on both sides of the socket body 10, the stability of the socket body 10 is ensured; the stepped contact layout and high-elastic alloy pins 11 are adopted to maintain the current-carrying capacity and signal integrity equivalent to the standard socket under the compact design, ensuring the electrical performance of the socket body 10, avoiding affecting the stability and electrical performance of the socket body 10 and the spatial layout of the surrounding components due to size changes, adapting to high-density circuit layouts, with stable connection and meeting the usage requirements.

[0023] It should be noted that the number of pins 11 of the socket body 10 in this embodiment can be 2×1Pin - 2×12Pin.

[0024] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments according to the technical solutions of the present invention still fall within the scope of the technical solutions of the present invention.
