DETAILED DESCRIPTION

[0020] The embodiments of the utility model will be described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other examples obtained by the ordinary skilled in the art without making creative efforts belong to the scope of protection of the utility model.

[0021] In combination with Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown, a signal line with a card connector joint includes a shielded wire 1, the two ends of which are respectively connected with a male head 2 and a female head 3, both of which follow the standard card interface specification, ensuring wide compatibility and flexibility of application.

[0022] The male head 2 and the female head 3 have an insertion end 4 connected with external devices, facilitating quick and accurate plugging and improving the convenience of operation. In addition, the connection end 5 connected with the core of the shielded wire 1 not only ensures high reliability of electrical connection, but also effectively resists vibration and tension, prolonging the service life of the signal line. The precise machining of the connection end 5 and the selection of high-quality materials further improve the stability and efficiency of signal transmission.

[0023] In order to further enhance the protection performance of the connection part, a sealing protection mechanism 6 is provided around the connection end 5, which includes a connecting head 61 arranged on the connection end 5, which is tightly attached to the connection end 5, forming a preliminary sealing barrier. The connecting head 61 is connected with a protective sleeve 62, which has good flexibility and sealing performance, and can tightly wrap around the periphery of the connection end 5, forming an additional protective layer. The protective sleeve 62 wraps around the periphery of the connection end 5. Not only can it effectively prevent moisture, dust and other pollutants from entering the connection part, but also can to some extent alleviate the impact of external impact and vibration on the stability of the connection, thereby ensuring the long-term reliable operation of the signal line.

[0024] In combination with Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the connecting head 61 is provided with external threads 611, and the inner wall of the protective sleeve 62 is provided with internal threads 621 matched with the external threads 611, which not only simplifies the installation process, but also makes it easy for users to achieve tight connection with the connecting head 61 by rotating the protective sleeve 62, and greatly improves the stability and sealing performance of the connection.

[0025] The protective sleeve 62 is wrapped around the periphery of the connection end 5 through threaded connection. In actual application, the protective sleeve 62 is tightly wrapped around the periphery of the connection end 5 through the threaded connection of its internal threads 621 and external threads 611. Not only can it effectively prevent moisture, dust and other pollutants from entering the interior through the connection gap, causing damage to the connection end 5 and the shielded wire 1, but also can to some extent alleviate the impact of external impact and vibration on the stability of the connection. At the same time, due to the fastening of the threaded connection, the protective sleeve 62 is not easy to loosen or fall off during long-term use, thereby ensuring the long-term reliable operation of the signal line.

[0026] When the protective sleeve 62 needs to be replaced due to long-term use or accidental damage, the user can easily remove it from the connector 61 by reversing the rotation, and then install a new protective sleeve 62. Not only reduces the maintenance cost, but also improves the maintainability and service life of the signal line.

[0027] In combination Figure 1 , Figure 2 , Figure 3 and Figure 4 , the insertion end 4 includes a shell 8, which not only has excellent mechanical strength and impact resistance, but also can effectively resist corrosion and pollution in the external environment, thereby prolonging the service life of the insertion end 4. A plurality of terminal blocks 7 are arranged inside the shell 8. The number and arrangement of the terminal blocks 7 are customized according to the specific application scenarios and transmission requirements of the signal line, to meet the connection requirements of different devices and systems. During the plugging process, it can tightly fit with the interface of the external device to form a reliable electrical connection.

[0028] In combination Figure 2 , Figure 3 , Figure 4 and Figure 5 , the insertion end 4 of the male head 2 is provided with a metal ring 21, which not only improves the overall aesthetics, but also reduces friction and resistance during plugging, and improves the smoothness and stability of the connection.

[0029] A positioning hole 22 is formed on the metal ring 21. Through the positioning hole 22, the user can use screws, buckles 33 and other fixing elements to firmly install the male head 2 on the device or panel, avoiding connection problems caused by loosening or falling off. At the same time, the position and number of the positioning hole 22 can also be customized according to actual needs to meet the requirements of different application scenarios and installation environments. Not only reduces the maintenance cost, but also improves the maintainability and service life of the signal line.

[0030] In combination Figure 2 , Figure 3 , Figure 4 and Figure 5 , the insertion end 4 of the female head 3 is provided with a mounting groove 31, which not only provides convenience for subsequent assembly and fixation, but also enhances the stability and reliability of the connection between the female head 3 and the external device.

[0031] The mounting groove 31 is provided with a spring 32, which not only has excellent mechanical strength and fatigue resistance, but also can quickly recover to its original shape when subjected to external force, thereby ensuring the stability and reliability of the buckle 33.

[0032] The spring 32 is provided with a buckle 33. It realizes the firm connection of the external device.

[0033] In practical application, when the female head 3 needs to be connected with an external device, the user only needs to press the buckle 33, press the elastic sheet 32 downward, make the buckle 33 flush with the surface of the female head 3, insert the female head 3 into the interface of the external device, and release the buckle 33 after the female head 3 is fully inserted. The buckle 33 will quickly pop up under the elastic force of the elastic sheet 32, thereby realizing the firm connection of the plug. Not only does it simplify the connection process and improve the convenience of connection, but also ensures the stability and reliability of the connection.

[0034] In combination with Figure 2 , Figure 3 and Figure 4 , the outer side of the buckle 33 is provided with sawtooth-shaped anti-falling lines 331. The locking effect and anti-falling ability of the buckle 33 are greatly enhanced. The edges of the sawtooth-shaped anti-falling lines 331 are sharp and uniformly distributed, which can provide greater friction and resistance when subjected to external force. Not only does it increase the contact area between the buckle 33 and the interface of the external device, but also effectively prevents the female head 3 from accidentally falling off or loosening under the action of vibration or external force through its sawtooth-shaped structure.

[0035] In practical application, when the female head 3 is connected with an external device, the buckle 33 will quickly close under the elastic force of the elastic sheet 32 and tightly grip the corresponding part of the plug. At this time, the sawtooth-shaped anti-falling lines 331 can tightly engage the surface of the connector, forming a solid anti-falling barrier. Even in complex external environments such as vibration, impact, etc., the buckle 33 can ensure that the plug is always firmly connected to the female head 3 and will not fall off or loosen due to external force.

[0036] In order to improve the stability and safety of the user during operation, in combination with Figure 1 , Figure 2 and Figure 3 , the surface of the shell 8 and the protective sleeve 62 is provided with anti-slip lines. By increasing the roughness and friction of the surface, it prevents accidental falling or operation errors caused by slippery hands during plugging, holding or rotating. Not only does it improve the texture of the shell 8, but also makes the user feel more stable and comfortable when holding. In the plugging process, the anti-slip lines can effectively prevent the shell 8 from falling off due to slippery hands, thereby ensuring the stability and safety of the operation.

[0037] In order to ensure the stability, durability and overall aesthetics of the connection, in combination with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the shell 8 is integrally formed with the protective sleeve 62 by injection molding process, which ensures a seamless connection between the shell 8 and the protective sleeve 62, eliminates the gaps and interfaces that may exist in the conventional connection mode, and thus improves the overall sealing performance and waterproof and dustproof capability.

[0038] The preferred specific embodiment of the utility model is described above, but the protection scope of the utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model carries out equivalent replacement or change, and all should be covered in the protection scope of the utility model.
