[0027] See also Figure 1-9The utility model provides a technical solution: a new type of socket harness connector fixing structure, including a socket PCB welding assembly 1, a socket input harness 9, and a harness connector 12. The socket PCB welding assembly 1 is composed of a red and green LED 2, a socket grounding plug 3, a socket left plug 4, a socket right plug 5, a socket spring bracket 6, a direct-mounted small switch 7, and a socket PCB board 8; the harness connector 12 is composed of a crimping terminal 10 and a pin seat 11. The socket input harness 9 is provided with two types, one of which is provided with a crimping terminal 10 at one end, and the crimping terminal 10 is connected to the socket PCB board 8. The pin sockets 11 are connected to each other; another socket input harness 9 is twisted and tinned, and is welded to the socket PCB board 8; the socket PCB board 8 is provided with reserved holes for plugging and assembling with the red and green LEDs 2, the socket grounding plug 3, the socket left plug 4, the socket right plug 5, the socket spring bracket 6, and the direct-mounted small switch 7, and is welded and fixed by automatic wave soldering equipment; the socket input harness 9 is connected to the socket PCB welding assembly 1 through the harness connector 12, and is welded and fixed by automatic wave soldering equipment using solder, together forming a socket output module assembly 14.

[0028] Furthermore, the socket output module assembly 14 is fastened by a snap-fit ​​structure reserved on the socket bottom 18 , and the socket bottom 18 is equipped with a socket top cover 16 that are snap-fitted to each other, and the socket bottom 18 and the socket top cover 16 together constitute the socket finished product 13 .

[0029] Furthermore, the socket upper cover 16 is hinged with a socket flip cover 15 , and a socket protection door mechanism 17 is provided in the socket finished product 13 to be assembled with the socket output module assembly 14 .

[0030] Furthermore, the head of the crimping terminal 10 has an anti-pin-backward structure, which is arranged as a gourd-shaped structure with a conical end; the head size of the anti-pin-backward structure is larger than the diameter of the reserved hole on the socket PCB board 8.

[0031] Furthermore, an inverted spring piece is provided on the side of the crimping terminal 10 , and the inverted spring piece and the inverted spring piece stopper reserved on the pin seat 11 are mutually clamped.

[0032] Furthermore, the crimping terminal 10 is formed by stamping phosphor bronze, and the surface is plated with conductive metal; the pin seat 11 is formed by injection molding of nylon 66.

[0033] Working principle: In the socket input harness 9, the length of each sub-wire is pre-cut into place using an automatic wire cutting machine and the end is peeled. A crimping terminal 10 with an anti-pin-retraction structure is crimped to the end of each sub-wire, and then all sub-wires with crimping terminals 10 are inserted into the pin seat 11 according to the wiring harness drawing to form an input harness connector 12, and the remaining socket input harness 9 is twisted and tinned. On the socket PCB board 8, the direct-mounted small switch 7, the socket spring bracket 6, the socket grounding plug 3, the socket left plug 4, the socket right plug 5, and the red and green LED 2 are inserted in sequence according to the position, and then the automatic wave soldering equipment is used for soldering to complete the production of the socket PCB welding assembly 1.

[0034] The socket input harness 9 and the socket PCB welding assembly 1 are welded by solder through an automatic wave soldering device to form a socket output module assembly 14, which can be directly fastened with the socket bottom 18 through the buckle reserved on the socket bottom 18. The socket bottom 18 can be fastened to the socket cover 16 through the buckle on the bottom to complete the assembly of the socket finished product 13. Using the crimping terminal 10 with an anti-pin-retraction structure to crimp the harness and the harness connector 12 combined with the pin seat 11, the required harness in the socket input harness 9 can be inserted into the socket PCB board 8 at one time for welding; for the additional socket input harness 9, that is, the neutral wire, the live wire, and the ground wire, the tinned twisted wire part can be easily inserted into the guide hole of the socket PCB board 8 through the guide hole on the socket spring bracket 6. After the socket input harness 9 and the socket PCB welding assembly 1 are welded, the socket output module assembly 14 is formed, which realizes the function of the socket design through the printed circuit in the socket PCB board 8. The harness connector 12 can ensure the correctness of each line sequence by conducting a conduction test in advance, and make the connection effect between all sub-wires with crimping terminals 10 and the socket PCB board 8 consistent and stable, thereby improving the consistency and quality stability of the product. At the same time, it can also avoid the confusion of the wiring inside the socket, especially when there are multiple signal harnesses that need to be connected, which can significantly improve the welding and assembly efficiency of the socket. Furthermore, the use of the fixed structure of this harness connector 12 can further improve the utilization rate of the internal space of the socket, especially in small sockets or socket products with high integration, the fixed structure of this harness connector 12 has more obvious advantages in improving production efficiency, safety, and stability.

[0035] During the process of inserting the harness connector 12 into the socket PCB board 8, since the head of the crimping terminal 10 has a gourd-shaped anti-pin-retraction structure, that is, the size of the terminal head is slightly larger than the diameter of the reserved hole on the socket PCB board 8 and the middle part of the terminal, and the raw material has good elasticity, the head bending structure is compressed during insertion so that it can pass through the socket PCB board 8 smoothly, and the terminal head immediately rebounds to the size before compression after passing through. After rebounding, the head of the crimping terminal 10 interferes with the reserved hole on the socket PCB board 8, making it impossible for the harness connector 12 to be easily pulled out or withdrawn from the socket PCB board 8. The side of the crimping terminal 10 has an inverted spring piece to prevent itself from falling out of the pin seat 11 after insertion; the pin seat 11 structure reserves an inverted spring piece block to cooperate with the crimping terminal 10 to achieve the anti-retraction function. During the process of inserting the crimping terminal 10 into the pin seat 11, the spring sheet is compressed first. After the crimping terminal 10 is fully in place, the spring sheet bounces up and is blocked by the reverse stopper. The two interfere with each other, and the crimping terminal 10 cannot be easily separated from the pin seat 11. The connection method between the socket input harness 9 and the socket PCB welding assembly 1 is simple and fast, with high installation efficiency, low solder consumption, and short welding time. It can be selected to use automated or manual equipment for welding according to the situation. Choosing automated production can greatly improve product production efficiency. Compared with directly manually welding the harness to the PCB, the efficiency can be increased several times. The socket PCB board 8 used in conjunction is a small printed circuit board, which has the advantages of being sturdy and durable, easy to install, space-saving, high reliability, and strong designability. It is suitable for welding, fixing and installing with the harness connector 12. The flying wire inside the socket is eliminated, which not only reduces the amount of harness and reduces the cost, but also can effectively improve the fireproof performance and structural aesthetics of the socket. Moreover, the selected parts are all flame-retardant engineering materials, eliminating the hidden danger of fire. The use of the pin holder 11 reduces the area and position of the exposed wires, and the nylon pin holder 11 is insulated on the outside of the metal conductor, reducing the risk of short circuit inside the socket and the risk of electric shock to personnel. The crimping terminal 10 is stamped from phosphor bronze, and the surface is tinned or plated with other conductive metals as required, and has good elasticity and conductivity; the pin holder 11 is injection molded from nylon 66, and has good high temperature resistance, insulation and structural strength. The phosphor bronze used in the crimping terminal 10 is a common raw material for the crimping terminal 10, and has excellent stamping performance, and can meet the design requirements of complex shapes, such as the bending structure of the terminal head and the undercut of the spring clip. The nylon 66 used in the pin holder 11 has the advantage of good molding effect for complex structures.
