[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses an anti-disconnection signal conversion device. (Refer to...) Figure 1 , Figure 2 and Figure 3 A signal conversion device with anti-disconnection capability includes a signal converter body 1, a plug 2 on one side of the signal converter body 1, and an anti-disconnection mechanism 3 on the surface of the signal converter body 1.

[0023] The anti-disengagement mechanism 3 includes a connector 301, which is located on one side of the signal converter body 1. Two locking blocks 302 are fixedly connected to the surface of the plug 2. Two slots 303 are formed on the inner wall of the connector 301. The surface of the locking blocks 302 contacts the inner wall of the slots 303. An annular groove 304 is formed at one end of each slot 303. The annular groove 304 cooperates with the locking blocks 302. A torsion spring 305 is provided on the inner wall of the signal converter body 1. The torsion spring 305 cooperates with the connector 301. By setting up the anti-disengagement mechanism, the mechanism is designed to prevent disengagement. Mechanism 3, by setting a locking block 302 on the surface of plug 2, and opening a locking groove 303 and an annular groove 304 on the inner wall of connector 301, works in conjunction with torsion spring 305. When the locking block 302 is in the annular groove 304, it can lock plug 2 and signal converter body 1, preventing plug 2 from accidentally falling off due to external pulling or other reasons, and ensuring the stability of signal transmission. At the same time, connector 301 can prevent dust from entering the connection between plug 2 and signal converter body 1, reducing problems such as poor contact caused by the accumulation of dust and other impurities.

[0024] Reference Figure 3A limiting block 11 is fixedly connected to the bottom of the connecting seat 301. A limiting groove 10 is opened on the inner wall of the signal converter body 1. The limiting block 11 is rotatably connected to the inner wall of the limiting groove 10. The connecting seat 301 is rotatably connected to one side of the signal converter body 1 through the limiting block 11 and the limiting groove 10. By setting the limiting block 11 and the limiting groove 10, the connecting seat 301 can be connected to the signal converter body 1, ensuring the stability of the rotation of the connecting seat 301.

[0025] Reference Figure 2 and Figure 4 A spring sleeve 4 is fitted on the surface of the plug 2. Both ends of the spring sleeve 4 are fixedly connected to clamps 5. The clamps 5 are set on the surface of the plug 2. By setting the spring sleeve 4 and the clamps 5, the bend of the plug 2 can be provided with additional support and protection, and the bend of the plug 2 can be prevented from bending excessively.

[0026] Reference Figure 4 Both clamps 5 have bolts 6 threadedly connected to their surfaces, and nuts 7 are threadedly connected to the other end of bolts 6. The clamps 5 are fixedly connected to the surface of plug 2 by bolts 6 and nuts 7. The bolts 6 and nuts 7 are used to fix the spring sleeve 4 and clamps 5, ensuring that the spring sleeve 4 and clamps 5 can be fitted onto the surface of plug 2.

[0027] Reference Figure 4 One of the clamps 5 has a positioning block 8 fixedly connected to its inner wall, and the plug 2 has a positioning groove 9. The surface of the positioning block 8 contacts the inner wall of the positioning groove 9. By setting the positioning block 8 and the positioning groove 9, the clamp 5 at one end can be connected to the plug 2, so as to prevent the spring sleeve 4 and the clamp 5 from shifting when the plug 2 is bent.

[0028] Reference Figure 3 The inner wall of the signal converter body 1 is provided with a groove 12. The torsion spring 305 is disposed in the inner cavity of the groove 12. One end of the torsion spring 305 is fixedly connected to the inner wall of the groove 12, and the other end of the torsion spring 305 is fixedly connected to the bottom of the connecting seat 301. By providing the groove 12, the installation space for the torsion spring 305 can be provided, and the torsion spring 305 can be prevented from shifting during the torsion process.

[0029] Working principle: When connecting plug 2 to signal converter body 1, the user inserts plug 2 into clamp 5 and spring sleeve 4, and engages the positioning block 8 in the clamp 5 at one end with the positioning groove 9 of plug 2, thus fixing clamp 5 to plug 2 at one end. Bolt 6 and nut 7 are used to further tighten clamp 5, ensuring it fits tightly against the surface of plug 2 and preventing slippage or loosening during use. Spring sleeve 4 is located at the easily bent part of plug 2 and has good flexibility and resilience, providing necessary support when plug 2 is subjected to external forces, preventing damage caused by excessive bending. The user rotates connector 301 to... The slot 303 inside the connector 1 is aligned with the locking block 302 on the surface of the connector 2. The connector 301 rotates in the limiting groove 10 through the connected limiting block 11, which can limit the connector 301. When the connector 301 rotates, the torsion spring 305 in the groove 12 will also rotate and store the torsional force. After the user inserts the connector 2 into the signal converter body 1, the locking block 302 will enter the annular groove 304. At this time, the user releases the rotating connector 301. Due to the force of the torsion spring 305, the connector 301 will rebound, so that the locking block 302 is firmly embedded in the annular groove 304, thereby locking the connection between the connector 2 and the signal converter body 1.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
