Cable joints are used to lock and secure incoming and outgoing cables, providing waterproofing, dustproofing, and vibration protection. However, existing cable joints often lack sufficient clamping force for the incoming and outgoing cables, thus failing to achieve the desired locking and securing effect. Summary of the Invention

[0005] Preferably, the height of the clamping ridge increases sequentially from the outside to the inside.

[0006] Preferably, the inner wall of the first connecting cavity is provided with an internal thread, and the outer surface of the male connector is provided with an external thread, and the external thread is threadedly connected to the internal thread.

[0007] Preferably, the first connecting cavity has a connecting position for limiting and fixing the annular sealing cylinder, and the surface of the connecting position is connected to the rear end face of the annular sealing cylinder.

[0008] Preferably, a cavity is formed between the inner wall surface of the first connecting cavity and the outer wall surface of the annular sealing cylinder to facilitate threaded connection of the male connector.

[0020] like Figure 1-2This is a schematic diagram of a preferred embodiment of the present invention for a cable connector. In this embodiment, the cable connector mainly includes a male connector 1 and a female connector 2. The female connector 2 has the following structure: a cylindrical first connecting cavity 21 is formed axially inside the female connector 2. An internal thread 23 is machined on the inner wall of the first connecting cavity 21. An annular connecting position 24 is formed at the bottom of the first connecting cavity 21. This connecting position 24 is a raised stepped surface used to axially limit the annular sealing cylinder 22. The annular sealing cylinder 22 is fixedly installed inside the first connecting cavity 21, with its rear end face abutting against the surface of the connecting position 24, thus being axially fixed. A certain gap is left between the outer wall surface of the annular sealing cylinder 22 and the inner wall surface of the first connecting cavity 21, forming a cavity 25. This cavity 25 provides the necessary space for the male connector 1 to be screwed in, avoiding interference. Multiple clamping ridges 221 are uniformly fixedly connected circumferentially to the inner wall of the annular sealing cylinder 22. These clamping ridges 221 extend axially along the annular sealing cylinder 22. Crucially, the height of these clamping ridges 221 increases sequentially from the outer end near the inlet of the annular sealing cylinder to the inner end near the connection position 24.

[0021] In this embodiment, the male connector 1 has a second connecting cavity 11 axially formed inside, and an external thread 14 is machined on the outer wall surface of the male connector 1. The external thread 14 matches the internal thread 23 of the female connector 2. A clamping sleeve 12 is fixedly installed in the second connecting cavity 11. The clamping sleeve 12 is cylindrical in shape, and its outer wall contacts the clamping ridge 221.

[0022] Working principle

[0023] In practical use, align the male connector 1 with the female connector 2, and screw the external thread 14 of the male connector 1 into the internal thread 23 of the female connector 2. As the male connector 1 is screwed in, its end gradually enters the first connecting cavity 21 of the female connector 2. At this time, the clamping sleeve 12 installed in the second connecting cavity 11 begins to contact and insert into the annular sealing cylinder 22 of the female connector 2. The outer wall surface of the clamping sleeve 12 contacts the clamping ridge 221 on the inner wall of the annular sealing cylinder 22. Since the height of the clamping ridge 221 increases from the outside to the inside, when the clamping sleeve 12 moves axially inward as the male connector 1 is screwed in, the clamping sleeve 12 first contacts the lowest point of the clamping ridge 221, generating initial contact pressure. As the screwing depth increases, the clamping sleeve 12 continues to move inward, gradually contacting the higher inner clamping ridge 221. Due to its higher height, the clamping ridge 221 causes the clamping sleeve 12 to be compressed to a greater extent, thereby generating a progressively increasing radial clamping pressure. The clamping sleeve 12 is deformed as it is squeezed by the clamping ridge 221, ensuring that the clamping force can be applied evenly and effectively to the clamping sleeve 12. Finally, a reliable radial clamping force is formed between the outer wall of the clamping sleeve 12 and the annular sealing cylinder 22, thereby further ensuring the clamping force on the cable. At the same time, the reliable clamping force can generate a reliable seal.

[0024] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
