Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a plug and socket assembly. Background Technology

[0002] Plug and socket assemblies are widely used in various electrical appliances and are an important component of power transmission. With the continuous improvement of electrification, the safety and reliability of plugs and sockets have become a major concern. Existing plug and socket designs are diverse, aiming to improve the stability and safety of connections and reduce failure rates and safety hazards.

[0003] Currently, common solutions to address issues like poor contact and wire detachment that may occur during plug and socket use include: first, using metal springs to enhance contact pressure and ensure good electrical contact; second, improving the overall insulation performance of the plug and socket by adding insulating materials to prevent short circuits and leakage; and third, using screws to securely fix the wires inside the plug, ensuring they don't loosen or detach. However, these traditional solutions still have some shortcomings. For example, metal springs may fatigue and deform after prolonged use, leading to a decrease in contact pressure and consequently poor contact; while screw fastening is reliable, frequent disassembly and reassembly can damage the threads, reducing lifespan; and snap-fit ​​structures may have unreliable locking due to low manufacturing precision, also affecting the plug and socket's performance.

[0022] like Figure 1-2 As shown, the present invention discloses a plug and socket assembly, including a mounting block 1 and a guide head 2. One end of the mounting block 1 is provided with a first groove, and the inner wall of the first groove is provided with a second groove. The guide head 2 is fixedly disposed in the second groove. The other end of the mounting block 1 is provided with a plurality of third grooves that communicate with the second grooves. The plurality of third grooves are not interconnected, and each of the plurality of second grooves is provided with a first through hole that communicates with the second groove. A wire 3 is fixedly disposed in each of the plurality of third grooves. The wire 3 passes through the first through hole and is connected to the guide head 2. The other end of each of the plurality of wires 3 extends out of the third groove and passes through a wire threading assembly. Each of the plurality of wires 3 is connected to the wire threading assembly.

[0023] In this invention, the multi-layered arrangement of grooves and wires 3 ensures the stability and reliability of the plug and socket assembly, reduces the risk of poor contact and wire 3 detachment, and the connection method of the guide head and wires can effectively improve the overall performance of the plug and socket assembly.

[0024] This design, through the arrangement of multi-layered grooves and wires 3, ensures the stability and reliability of the plug and socket assembly, and reduces the risk of poor contact and wire 3 detachment.

[0025] In an optional embodiment, the outer end of the mounting block 1 is provided with two hand grips 7, which can be raised handles or recessed grip areas, making it easier and more convenient for users to plug and unplug the plug.

[0026] In an optional embodiment, the outer end faces of multiple wires 3 are provided with waterproof adhesive. This step can not only prevent moisture from entering the inside of the wires 3 and affecting the normal operation of the circuit, but also extend the service life of the wires 3, which is especially important when used in humid environments.

[0027] In an optional embodiment, the threading assembly includes a fixing block 4, on which a number of second through holes, equal to and corresponding one-to-one with a plurality of wires 3, are arranged side by side. The plurality of second through holes are interconnected, and the wires 3 pass through the second through holes and are connected to the fixing block 4 through connecting units. This design allows the wires 3 to be more evenly distributed inside the fixing block 4, avoiding damage to the wires 3 caused by local stress concentration.

[0028] In an optional embodiment, one end of the wire 3 passing through the second through hole is provided with a tin-immersion layer 6, which can act as a flux in subsequent installation and soldering processes, improving the quality and speed of soldering.

[0029] In an optional embodiment, the outer peripheral surface of the fixing block 4 away from the mounting block 1 is provided with an external thread 8, which can be connected to other components (such as cable sheaths) to form a complete protection system.

[0030] Specifically, the connecting unit includes welding adhesive 5. The wire 3 has a first notch at the second through hole, and the welding adhesive 5 is located at the first notch. The wire 3 is welded to the inner wall of the second through hole through the welding adhesive 5, and multiple first notches are staggered. This design can better distribute the heat of the welding point and avoid damage to the wire 3 due to local overheating.

[0031] Specifically, the welding adhesive 5 is a special polymer material with good flowability and adhesion. It can effectively fill the gap between the wire 3 and the second through hole, ensuring a tight contact between the two. The design of the first notch is to provide more welding area, thereby improving the reliability and stability of the welding. The staggered arrangement of multiple first notches can further disperse the heat at the welding point and reduce the possibility of local overheating;

[0032] The welding adhesive 5 and the specially designed first notch achieve an efficient and reliable connection between the wire 3 and the fixing block 4. The welding adhesive 5 not only fills the gap between the wire 3 and the second through hole but also provides additional mechanical support, improving overall stability and reliability. The design of the first notch further optimizes the welding process, avoiding potential risks from localized overheating. These improvements work together to ensure that this plug and socket assembly maintains excellent performance even in harsh environments such as high temperature and high humidity.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
