Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a plug-in connector. Background Technology

[0002] In electronic devices, connectors, as essential components for achieving electrical connections, are widely used in various electrical systems. Traditional connector structures typically include pins, a connector plate, and a base. The pins are inserted into the connector plate to form a pin assembly, and then the connector plate is assembled onto the base to achieve the electrical connection function.

[0003] However, this structure has certain drawbacks in practical applications. Since the pins are uniformly fixed to the connector plate, if one or more pins are damaged, bent, or have poor contact, the entire connector plate must be disassembled and replaced during repair or replacement, resulting in high maintenance costs, low efficiency, and wasted resources. Furthermore, the connection between the pins and the connector plate is usually fixed, lacking flexibility and hindering modular design and high-reliability maintenance. Therefore, an improved connector structure is urgently needed that allows for individual pin replacement, reducing maintenance costs, improving assembly and repair efficiency, and ensuring the reliability and stability of the electrical connection. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a splicing connector that can realize the individual replacement of the pins, reduce maintenance costs, and improve assembly and maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plug-in connector, comprising a base, a plug plate, and pins. The plug plate includes at least two assembly plates. The base has assembly cavities corresponding to the number of assembly plates. At least one locking block is provided on each of the longitudinal sides of the opening of the assembly cavity. Columnar structures are provided on each of the transverse sides. A vertical sliding groove is provided along the longitudinal direction of the columnar structures. A detachable stop block is provided at the end of the columnar structures. The stop block is used to cover or expose the vertical sliding groove. The assembly plate has a plug piece adapted to one of the vertical sliding grooves and an assembly seat corresponding to the locking block. The assembly seat has a second vertical sliding groove adapted to the locking block. The end face of the assembly plate has multiple pin slots for pin assembly. The first vertical sliding groove, the second vertical sliding groove, and the pin slots are all coaxially arranged.

[0006] The present invention is further configured such that: the columnar structure is located between two adjacent assembly cavities, and each of the assembly cavities on both sides is provided with a vertical sliding groove; the stop block is threadedly fixed to the columnar structure; and the height of the columnar structure with the stop block is greater than the height of the needle extending out of the needle groove.

[0007] The present invention is further configured such that: the first end of the stop is provided with a threaded block, and the tail end is provided in a frustum shape, with the end with the smaller bottom surface away from the threaded block.

[0008] The present invention is further configured such that: two locking blocks are provided on both sides of the assembly cavity along its longitudinal direction, and two assembly seats are provided at both ends of the assembly plate, with vertical sliding grooves adapted to the locking blocks on the assembly seats.

[0009] The present invention is further configured such that the assembly plate, insert, and assembly base are integrally formed.

[0010] By adopting the above technical solutions, individual replacement of pins within a small range can be achieved, reducing maintenance costs. There is no need to disassemble the entire connector board, making operation more convenient. The foolproof design of the stop block takes into account both safety and repair. The height of the detachable stop block on the columnar structure is higher than the exposed size of the pin, forming a physical barrier during transportation or maintenance to prevent the pin from being deformed by external forces. At the same time, setting the stop block to be detachable can also stabilize the assembly of the connector board and improve the compactness of the overall connector structure.

[0018] Reference Figures 1 to 6 The embodiments of this utility model will be further described below.

[0019] A plug-in connector includes a base 1, a plug plate 2, and pins 3. The plug plate 2 includes at least two mounting plates 20. The base 1 has mounting cavities 10 corresponding to the number of mounting plates 20. At least one locking block 11 is provided on each of the longitudinal sides of the opening of the mounting cavity 10. Columnar structures 12 are provided on each of the transverse sides. A vertical sliding groove 13 is provided along the longitudinal direction of the columnar structure 12. A detachable stop block 14 is provided at the end of the columnar structure 12. The stop block 14 is used to cover or expose the vertical sliding groove 13. The mounting plate 20 is provided with a insert 21 corresponding to the vertical sliding groove 13 and a mounting seat 22 corresponding to the locking block 11. The mounting seat 22 is provided with a vertical sliding groove 23 that is adapted to the locking block 11. The end face of the mounting plate 20 is provided with multiple pin slots for mounting the pins 3. The vertical sliding groove 13, the vertical sliding groove 23, and the pin slots are all coaxially arranged.

[0020] The columnar structure 12 is located between two adjacent assembly cavities 10, and each of the assembly cavities 10 on both sides is provided with a vertical sliding groove 13. The stop block 14 is threadedly fixed to the columnar structure 12. The height of the columnar structure 12 with the stop block 14 is greater than the height of the pin 3 extending out of the pin groove. The first end of the stop block 14 is provided with a threaded block 15, and the tail end is provided in a frustum shape, with the end with the smaller bottom surface away from the threaded block 15.

[0021] The assembly cavity 10 has two spaced locking blocks 11 on both sides along its longitudinal direction, and the assembly plate 20 has two assembly seats 22 at both ends. The assembly seats 22 are provided with vertical sliding grooves 23 that are adapted to the locking blocks 11. The assembly plate 20, the insert 21 and the assembly seats 22 are integrally formed.

[0022] Working principle: The insert plate 2 is composed of multiple independent assembly plates 20. After the pin 3 is assembled on each assembly plate 20, it is installed in the assembly cavity 10 of the base 1. During installation, the stop block 14 of the columnar structure 12 is first removed to expose the opening of the vertical slide groove 13. Then, the insert piece 21 on the assembly plate 20 is aligned with the vertical slide groove 13, and the vertical slide groove 23 on the assembly base 22 is aligned with the locking block 11 on the side wall of the assembly cavity 10. The assembly plate 20 is continuously pushed towards the assembly cavity 10 for fixed assembly. After the assembly plate 20 is in place, the stop block 14 is screwed onto the columnar structure 12 to further lock the assembly plate 20 in place. It has the advantages of convenient disassembly and assembly, and easy maintenance and replacement. After the stop block 14 is assembled, the height of the columnar structure 12 is greater than the height of the pin 3, which protects the pin 3 and prevents it from bending during transportation and storage.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
