Description

Technical Field

[0001] This invention belongs to the field of connector technology, and specifically relates to a splicing interlocking PIN header assembly for electrical connectors. Background Technology

[0002] As electronic devices continue to evolve towards miniaturization, high performance, and integration, the performance and reliability of electronic components have become key factors determining the overall performance of equipment. PIN header connectors, as electrical connection components widely used in various electronic devices, undertake the important tasks of signal transmission and power connection. With the increasing complexity of electronic product functions, the demand for connectors is no longer limited to simple connections, but requires higher stability, reliability, and flexible interlocking functions to adapt to diverse application scenarios and complex working environments. Traditional PIN header connectors have a fixed number of pins during the design phase, a limitation that becomes increasingly apparent when facing complex and ever-changing circuit functional requirements. When it is necessary to expand the number of connection points to accommodate more functional modules, the fixed-pin header connector often cannot directly meet the needs. While bolt splicing can be used to increase the number of connection points, this process is cumbersome, requiring manual operation of each connector individually, consuming significant time and labor costs, resulting in low assembly efficiency. Furthermore, bolt-spliced ​​connectors cannot achieve effective interlocking in their structure, and under vibration and impact, they are prone to loosening, leading to signal transmission interruption or instability, severely affecting the normal operation of the equipment. Summary of the Invention

[0003] (1) Technical problems to be solved To address the shortcomings of existing technologies, the present invention aims to provide a splicing interlocking PIN header assembly for electrical connectors. This addresses the problems of traditional PIN header connectors that use bolt splicing to increase the number of connection points, resulting in low assembly efficiency and inability to achieve effective interlocking. Furthermore, in vibration environments, these connectors are susceptible to various vibrations and impacts, which can easily lead to loosening and consequently signal transmission interruption or instability.

[0004] (2) Technical solution To address the aforementioned technical problems, this invention provides a splicing interlocking PIN header assembly for electrical connectors, comprising a plug, a socket, and a splicer. Both the plug and socket are formed by splicing multiple bases together. A pin is installed within the base of the plug, and a insertion hole for engaging the pin is provided within the base of the socket. The splicer is used to lock adjacent bases together. The splicer includes a detachably connected first locking member, a second locking member, and interlocking members disposed on the upper and lower sides of the first locking member. The first locking member includes a first locking ring and a first ratchet portion fixedly connected to both ends of the first locking ring. The second locking member includes a second locking ring and a second ratchet portion fixedly connected to both ends of the second locking ring. The shapes of the first and second ratchet portions are adapted to achieve mutual locking. When the first and second locking members are connected, the interlocking members on the plug and the interlocking members on the socket are locked together.

[0005] Preferably, locking points are provided at both ends of the base, and mating parts are formed on the inner sides of the first locking ring and the second locking ring. The locking points and mating parts are used to provide locking force to adjacent bases.

[0006] Preferably, the locking point includes an extension fixedly connected to both ends of the base, and both sides of the extension are fixedly connected with protrusions and form grooves. The mating part includes a limiting groove formed inside the first locking ring and the second locking ring. The inner walls of the front and rear sides of the limiting groove form a limiting platform corresponding to the groove between the outer surfaces of the first locking ring and the second locking ring.

[0007] Preferably, the groove is inclined on the side near the protrusion, and the inner walls of both the front and rear sides of the limiting groove are inclined.

[0008] Preferably, a positioning groove is provided on one side extension of the base, and a positioning post adapted to the positioning groove is fixedly connected to the other side extension of the base.

[0009] Preferably, the distance between the extension and the left and right sides of the base is different, so that the splicer does not protrude from the surface of the base.

[0010] Preferably, a flat surface is provided on the side of the first ratchet portion at both ends of the first locking ring that is close to each other, and the flat surface is used to fit against the surface of the extension portion.

[0011] Preferably, the interlocking component includes a fixed base, an elastic part, and a locking block connected in sequence. The fixed base is fixedly connected to the first locking ring. The fixed base has an insertion hole, and the inner top wall of the insertion hole has a locking groove that matches the locking block.

[0012] Preferably, the interlocking component is integrally formed with the first locking component, and the elastic part is a bent arc shape.

[0013] Preferably, the splicer is made of an elastic material to restore the disassembled interlocking components to their original shape.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In the above scheme, the connector plug and socket are designed as multiple independent modules. Each module contains a base and a certain number of pins or sockets. Users can select an appropriate number of modules to splice and combine according to the actual number of connection points required, so as to realize the flexible adjustment of the number of connector pins. Furthermore, modular assembly is carried out through the splicer, which not only makes the assembly firm but also improves the assembly efficiency. (2) In the above scheme, interlocking components are set on the upper and lower sides of the first locking component. When the plug pin is inserted into the socket, the locking block of the left interlocking component can be inserted into the socket. After the plug and socket are fully inserted, the restoring force of the elastic part makes the locking block lock in the slot, thereby forming a firm interlocking connection. This interlocking structure can effectively prevent the connector from loosening due to external force in a vibration environment, ensuring the stable and reliable connection between electronic devices. Moreover, the connector can be separated by a simple pressing action, which improves the operating efficiency. Attached Figure Description

[0019] like Figures 1-8As shown, an embodiment of the present invention provides a splicing interlocking PIN header assembly for an electrical connector, including a plug 1, a socket 2, and a splicer 3. Both the plug 1 and the socket 2 are formed by splicing multiple bases 4 together. Pins 5 are installed within the base 4 of the plug 1. The pins 5 can be straight or bent, and the number is 2-5. The base 4 of the socket 2 has a mating hole 6 that mates with the pins 5. An elastic conductive element is disposed inside the mating hole 6. The pins 5 are the conductive parts of the connector, responsible for transmitting electrical signals or power. The elastic conductive element ensures good contact with the pins 5, forming a conductive path and guaranteeing the stability and reliability of the connection. The pins 5, the elastic conductive element, and the connecting wires are shown in the schematic diagram. The splicer 3... Used to lock adjacent bases 4, bases 4 are made of engineering plastics with good insulation properties, such as polybutylene terephthalate (PBT) and liquid crystal polymer (LCP). These materials have high mechanical strength, good heat resistance, and dimensional stability, providing stable support and reliable insulation protection for the pins 5, ensuring that no electrical short circuits occur between the pins 5 under various working environments. The pins 5 are generally made of copper alloy materials with excellent conductivity, such as phosphor bronze and beryllium bronze. Copper alloy materials not only have excellent conductivity, effectively reducing resistance loss during signal transmission and ensuring stable signal transmission, but also have a certain degree of elasticity and mechanical strength, allowing the pins 5 to be inserted and removed from the elastic conductive parts. During the process, it can maintain good contact performance and is not easily deformed or broken; the splicer 3 includes a detachably connected first locking member 7, a second locking member 8, and interlocking members 9 disposed on the upper and lower sides of the first locking member 7. The first locking member 7 includes a first locking ring 701 and a first ratchet portion 702 fixedly connected to both ends of the first locking ring 701. The second locking member 8 includes a second locking ring 801 and a second ratchet portion 802 fixedly connected to both ends of the second locking ring 801. The shapes of the first ratchet portion 702 and the second ratchet portion 802 are adapted to achieve mutual locking. When the first locking member 7 and the second locking member 8 are connected to each other, the interlocking member 9 on the plug 1 locks with the interlocking member 9 on the socket 2, and a lock is formed between the interlocking member 9 and the first ratchet portion 702. The V-shaped structure, with the distance between the interlocking part 9 and the first ratchet 702 being greater than the thickness of the second ratchet 802, allows the connector's plug 1 and socket 2 to be designed as multiple independent modules. Each module includes a base 4 and a certain number of pins 5 or sockets 6. Users can select an appropriate number of modules to combine according to the actual number of connection points required, thus flexibly adjusting the number of connector pins. This design not only improves the connector's versatility and flexibility but also reduces the cost and difficulty of equipment upgrades and modifications. Furthermore, the modular design makes connector maintenance and replacement more convenient. When a module fails, only the corresponding module needs to be replaced, without replacing the entire connector, thus improving the availability and reliability of the equipment.

[0020] In this embodiment, locking points are provided at both ends of the base 4, and mating parts are formed on the inner sides of the first locking ring 701 and the second locking ring 801. The locking points and mating parts are used to provide locking force to the adjacent bases 4, so that the adjacent bases 4 will not move up, down, left, right or back and forth, and will be close together.

[0021] like Figures 1-4 As shown, in this embodiment, the locking point includes an extension 401 fixedly connected to both ends of the base 4. Both sides of the extension 401 are fixedly connected to a protrusion 402 and form a groove 403. The mating part includes a limiting groove 404 opened inside the first locking ring 701 and the second locking ring 801. The inner walls of the front and rear sides of the limiting groove 404 form a limiting platform 405 corresponding to the groove 403 between the outer sides of the first locking ring 701 and the second locking ring 801. By engaging and locking the first ratchet 702 of the first locking ring 701 with the second ratchet 802 of the second locking ring 801, that is, the ratchet of the first ratchet 702 and the second ratchet 802 are deformed by pressing, thereby locking and fixing, so that the limiting platform 405 is inserted into the groove 403, and the plane 7021 contacts the upper and lower sides of the extension 401, thereby firmly splicing the two bases 4 of the plug 1 together, without any front-back or left-right movement.

[0022] To ensure that the first locking member 7 and the second locking member 8 are pressed and fixed together, and the two bases 4 are tightly fixed, such as... Figure 6 As shown, in this embodiment, the side of the groove 403 near the protrusion 402 is inclined, and the inner walls of the front and rear sides of the limiting groove 404 are both inclined; in this way, after the limiting platform 405 is inserted into the groove 403, the inclined surface causes the two bases 4 to generate a force that brings them closer to each other, thus preventing loosening after fixing.

[0023] To make the two bases 4 more stable horizontally and vertically after splicing, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, a positioning groove 406 is provided on one side extension 401 of the base 4, and a positioning post 407 adapted to the positioning groove 406 is fixedly connected on the other side extension 401 of the base 4. The positioning post 407 has a round head structure to facilitate guidance and insertion. There are at least two of them to prevent rotation after the two bases 4 are inserted. When splicing, the two bases 4 of the plug 1 are brought close together. At this time, the positioning post 407 on the rear side of the base 4 is inserted into the positioning groove 406 on the front side of the base 4. The positioning post 407 and the positioning groove 406 are slightly interference-fitted to perform initial positioning and prevent movement.

[0024] In this embodiment, the distance between the extension 401 and the left and right side surfaces of the base 4 is different, so that the splicer 3 does not protrude from the surface of the base 4, such as... Figure 1 and Figure 5As shown, the second locking ring 801 of the plug 1 will be recessed into the base 4, so that after the plug 1 and the socket 2 are connected, the pin 5 can be fully inserted into the socket 6 without being blocked by the splicer 3.

[0025] like Figure 1 and Figure 4 As shown, in this embodiment, a plane 7021 is provided on one side of the first ratchet portions 702 at both ends of the first locking ring 701 that are close to each other. The plane 7021 is used to fit against the surface of the extension portion 401. In this way, after the first locking member 7 and the second locking member 8 lock the adjacent base 4, the plane 7021 contacts the upper and lower sides of the extension portion 401 to prevent vertical movement.

[0026] To achieve interlocking between plug 1 and socket 2, such as Figure 1 , Figure 7 and Figure 8 As shown, in this embodiment, the interlocking component 9 includes a fixed base 901, an elastic part 902, and a locking block 903 connected in sequence. The fixed base 901 is fixedly connected to the first locking ring 701. The fixed base 901 has an insertion hole 904. The inner top wall of the insertion hole 904 has a locking groove 905 that matches the locking block 903. The interlocking component 9 is integrally formed with the first locking component 7. The elastic part 902 is a bent arc shape, and the end of the elastic part 902 near the locking block 903 is narrowed, so that the locking block 903 can be inserted into the insertion hole 904. The right side of the locking block 903 is arc-shaped, and the left side has a locking surface. When the pin 5 of the plug 1 is inserted into the socket 2, the locking block 903 of the left interlocking component 9 can be inserted into the insertion hole 904. After the plug 1 and the socket 2 are fully inserted, the restoring force of the elastic part 902 causes the locking block 903 to lock into the locking groove 905, thereby forming a firm interlocking connection.

[0027] In this embodiment, the splicer 3 is made of an elastic material to restore the original shape of the disassembled interlocking parts 9. The elastic material is an engineering plastic material with a certain deformation capacity, which allows the ratchet to deform during locking for better engagement.

[0028] The technical solution provided by this invention involves installing fixed pins 5 inside the base 4 of the plug 1. During assembly, the two bases 4 of the plug 1 are brought together tightly. At this time, the positioning pin 407 on the rear side of the base 4 is inserted into the positioning groove 406 of the front base 4. Initial positioning is achieved through the interference fit between the positioning pin 407 and the positioning groove 406. Then, the first locking member 7 and the second locking member 8 are placed on the left and right sides of the two bases 4. The first ratchet portion 702 of the first locking ring 701 and the second ratchet portion 802 of the second locking ring 801 are engaged to lock the limit platform 405 into the groove. Inside 403, the plane 7021 contacts the upper and lower sides of the extension 401, thereby firmly splicing the two bases 4 of the plug 1 together. Then, using the same method, the two bases 4 of the socket 2 are firmly spliced ​​together. Since interlocking members 9 are provided on the upper and lower sides of the first locking member 7, when the pin 5 of the plug 1 is inserted into the socket 2, the locking block 903 of the left interlocking member 9 can be inserted into the socket 904. After the plug 1 and the socket 2 are fully inserted, the restoring force of the elastic part 902 causes the locking block 903 to engage in the slot 905, thereby forming a firm interlocking connection.
