[0020] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0021] Please see Figures 1-5 In this embodiment of the utility model, a plug-in type three-stage male connector includes a male connector body, which includes an injection-molded fixing block 1, an outer insert tube 2, and an inner insert tube 3. The male connector body can be inserted into and contacted with an external female connector 12. A center pin 5 is passed through and fixedly connected to the fixing block 1. The inner insert tube 3 is fitted with the center pin 5 and fixedly installed on the fixing block 1. A second slot 7 for insertion into and contacting the female connector 12 is defined between the inner insert tube 3 and the center pin 5. The outer insert tube 2 is fitted with the inner insert tube 3 and fixedly installed on the fixing block 1. A first slot 6 for insertion into and contacting the female connector 12 is defined between the outer insert tube 2 and the inner insert tube 3. A first pin 8 and a second pin 9 that pass through the fixing block 1 are fixedly connected to the outer insert tube 2 and the inner insert tube 3, respectively.

[0022] Specifically, in this embodiment, the fixing block 1 provides stable support for the entire structure. The outer tube 2 and the inner tube 3 are made of metal with a certain degree of elasticity. When the male connector body is connected to the female connector 12, preliminary alignment is required. The external dimensions of the male connector and the interface dimensions of the female connector 12 are matched. The inner tube 3 and the outer tube 2 are inserted into the female connector 12, so that the male connector body and the female connector 12 are connected to form a connected structure, ensuring the transmission of lines and electrical signals. When the male connector body is inserted into the female connector 12, the first slot 6 between the outer tube 2 and the female connector 12 begins to function, and the corresponding structures of the outer tube 2 and the female connector 12 fit tightly together. At the same time, the second slot 7 between the inner tube 3 and the center pin 5 also engages with the female connector. The corresponding structure of 12 makes contact. The center pin 5 and the first pin 8 and second pin 9 on the outer tube 2 and inner tube 3 will make contact with the corresponding external conductive structure. For example, it can be installed on a circuit board or external circuit. When the male body is connected to the female 12, the electrical signal is conducted through the center pin 5, inner tube 3 and outer tube 2. The overall structure is simple to operate and suitable for various plug-in boards and very small electronic products. It can match the PCB board and can quickly perform soldering to prevent the soldering from being reversed. Secondly, it is simple and convenient to operate in the production process, with short loading and unloading time and high processing efficiency. The processed products greatly save manpower, materials and costs in this industry, improve the product yield and reduce the generation of defective products.

[0023] It should be noted that when the male connector needs to be removed, a certain external force is applied to overcome the friction between the male connector body and the female connector 12, thereby achieving the disassembly of the two. During the separation process, as the contact parts of the male connector body and the female connector 12 gradually separate, the electrical connection is also broken in sequence. Secondly, in practical applications, the shape and size of the fixing block 1 can be designed according to the specific usage scenario to ensure the matching degree between the male connector and the female connector 12. In addition, the material of the fixing block 1 can be selected as plastic with certain strength and insulation properties to ensure the electrical performance of the male connector.

[0024] In this embodiment of the utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, a through hole 10 is provided on the fixing block 1, and the center pin 5 is fixedly installed in the through hole 10. The first pin 8 and the second pin 9 are arranged opposite to each other along the center pin 5. Specifically, the first pin 8 and the second pin 9 are arranged opposite to each other along the center pin 5 to avoid contact between the outer tube 2 and the inner tube 3, thus ensuring the normal use of the device. It should be noted that in actual applications, the length and position of the first pin 8 and the second pin 9 can be adjusted according to specific usage requirements.

[0025] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, multiple grooves 4 are spaced apart along the circumference of the inner tube 3 and the outer tube 2. Specifically, the arrangement of multiple grooves 4 allows the inner tube 3 and the outer tube 2 to undergo a certain deformation relative to their own axis. At the same time, under the elasticity of the outer tube 2 and the inner tube 3, the mating contact between the two and the female socket 12 can be tighter, thereby improving the stability of the connection between the male head body and the female socket 12.

[0026] In this embodiment of the utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, the top of the fixing block 1 has multiple fixing grooves 11, which are specifically used to fix external wires.

[0027] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 5 Figure 1 Figure 2 Figure 5 As shown, the inner tube 3, outer tube 2, and center pin 5 are preferably made of copper. Specifically, copper has good electrical and thermal conductivity. Therefore, choosing copper as the material for the inner tube 3, outer tube 2, and center pin 5 can improve the electrical and heat dissipation performance of the male connector. In practical applications, in addition to copper, other materials with good electrical and thermal conductivity can also be selected, such as silver and aluminum. Furthermore, the cost and processing difficulty of the material should also be considered when selecting materials.

[0028] Working principle: When the male connector is inserted into the female connector 12, the first slot 6 between the outer tube 2 and the female connector 12 begins to function, and the corresponding structures of the outer tube 2 and the female connector 12 fit tightly together. At the same time, the second slot 7 between the inner tube 3 and the center pin 5 also contacts the corresponding structure of the female connector 12. The first pin 8 and the second pin 9 on the center pin 5, the outer tube 2, and the inner tube 3 will contact the corresponding external conductive structure, such as a circuit board or external circuit. After the male connector is connected to the female connector 12, the electrical signal is conducted through the center pin 5, the inner tube 3, and the outer tube 2. The overall structure is simple to operate and suitable for various plug-in boards and very small electronic products. It can match PCB boards and can quickly perform soldering, preventing reverse soldering. Furthermore, it is simple and convenient to operate during production, with short loading and unloading time and high processing efficiency. The processed products greatly save manpower, materials, and costs in the industry, improve product yield, and reduce the production of defective products.
