[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-2 As shown, the present invention proposes a four-core plug-in male connector, including a mounting block 1. One end of the mounting block 1 is provided with a first groove 2. The inner wall of the first groove 2 is provided with a second groove for mounting a guide head 4. The guide head 4 is fixedly disposed in the second groove. The other end of the mounting block 1 is provided with a plurality of third grooves arranged side by side. The plurality of third grooves are all interconnected with the second groove, but are not interconnected with each other. A wire 5 is fixedly disposed between the plurality of third grooves. The plurality of wires 5 are respectively connected to the guide head 4. A limiting component for mating installation is provided in the first groove.

[0024] The implementation principle of this embodiment is as follows: by optimizing the design and installation method of the guide head 4, and by reasonably arranging the third groove and the wire 5, the four-core plug-in male connector can still maintain good electrical performance and mechanical stability after multiple plugging and unplugging, which solves the problem of poor contact and short circuit of traditional connectors in complex application environments. Furthermore, the limiting component can effectively improve the stability of the device during subsequent use.

[0025] Specifically, mounting block 1 is the basic structure of the entire four-pin male connector and can be made of various materials. For example, commonly used materials include ABS plastic, high-strength engineering plastics such as nylon, and metal materials such as aluminum alloy and stainless steel can also be used to improve its mechanical strength and durability. Mounting block 1 is manufactured by injection molding, which has high precision and consistency.

[0026] The length of mounting block 1 is preferably 23 mm, which ensures sufficient mechanical strength without being too bulky and easy to operate.

[0027] A portion of the guide head 4 can extend from the first groove 2 for better docking with other components. The distance by which the guide head 4 extends out of the first groove 2 is preferably 5 mm. This ensures the effective contact area of ​​the guide head 4 while avoiding damage caused by excessive length. The extension distance and shape design of the guide head 4 help to increase the contact area and contact pressure, reducing the risk of poor contact.

[0028] The second groove is located on the inner wall of the first groove 2 and is used to fix the guide head 4. The shape and size of the second groove need to match the guide head 4 to ensure that the guide head 4 can be firmly embedded therein.

[0029] The third groove is located at the other end of the mounting block 1, arranged side by side, with the number matching the number of pins on the guide head 4. Each third groove is connected to the second groove, forming a closed channel, allowing the wire 5 to pass through smoothly and connect to the guide head 4. The width and depth of the third groove need to be adjusted appropriately according to the diameter of the wire 5 to ensure that the wire 5 can be inserted smoothly without twisting or breaking. To prevent the wire 5 from loosening during repeated insertion and removal, an elastic clamping device, such as a rubber washer or spring sheet, can be installed at the entrance of the third groove. These devices can, to some extent, offset the effects of external vibrations and maintain the stability of the wire 5.

[0030] The conductor 5 is typically made of copper or aluminum wire and wrapped with an insulation layer to prevent current leakage. To improve the soldering performance of the conductor 5, a tin-impregnated layer 7 can be provided on the outer circumference of both ends, especially at the end near the conductor head 4. The length of the tin-impregnated layer 7 is preferably 2.5 mm. This design not only facilitates the formation of solder joints but also reduces contact resistance and improves signal transmission efficiency.

[0031] If conditions permit, the surface of conductor 5 can also be coated with an anti-corrosion coating, such as epoxy resin or polyurethane, to extend its service life.

[0032] The handheld part 6 is a structure designed to facilitate user grip and operation. It is generally set on the outer peripheral surface of the mounting block 1. The number and position of the handheld part 6 can be adjusted according to actual needs. For example, two opposing handheld parts 6 can be set on both sides of the mounting block 1 with a moderate distance between them, which is convenient for one-handed operation.

[0033] The handle 6 can be cylindrical, oval, or other ergonomically designed, and its surface can be textured with anti-slip patterns to increase friction and prevent slippage. Furthermore, the color and material of the handle 6 can differ from the main body of the mounting block 1, serving a visual guidance function to help users quickly identify the correct operating part.

[0034] The elastic clamping device in the third groove can absorb external vibrations to a certain extent and protect the wire 5 from damage; the design of the handheld part 6 improves the user's operating convenience and comfort, and improves the overall reliability of the product and user experience.

[0035] In an optional embodiment, the limiting component includes a locking block 8, a transmission block 9, and a spring 10. A fourth groove is provided on the inner wall of the first groove. The locking block 8 is slidably disposed in the fourth groove. The locking block 8 and the inner wall of the fourth groove are connected by the spring 10. The outer end of the mounting block 1 is provided with a first through hole that communicates with the inner wall of the fourth groove. The transmission block 9 is slidably disposed in the first through hole and connected to the locking block 8. After the device is installed, the locking block 8 and the spring 10 can abut against the inner wall of the groove of the mating connector, thereby improving the stability of the mating. Furthermore, the transmission block 9 can easily drive the locking block 8 to move, thereby eliminating the need for fixing between the mating parts.

[0036] 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. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
