Description

Technical Field

[0001] The utility model relates to the technical field of silicone plugs, in particular to a cable silicone plug. Background Art

[0002] Cable silicone plugs are usually made of silicone material. This material is soft, durable, and has excellent high-temperature resistance, corrosion resistance, and insulation properties. The function of cable silicone plugs is to fix and protect cables. Cables often need to be connected to various devices. If the cables are loose or fall off, it may cause equipment failures or safety hazards. Using cable silicone plugs can effectively prevent this phenomenon from occurring and improve the safety and stability of the equipment.

[0003] Application No. 201920406930.5 discloses a cable silicone plug, including a silicone seat, a wire splitting seat, and a hard shell protection seat. The wire splitting seat is connected above the silicone seat. The silicone seat and the wire splitting seat are connected inside the hard shell protection seat. The silicone seat is provided with a wire passing hole, a fixing ring, and two anti-slip mechanisms. The anti-slip mechanisms are evenly distributed inside the fixing ring. It has good sealing effect and waterproof property, and adding a hard shell protection seat can prevent rats from biting and affecting the use of the cable.

[0004] The above solution has deficiencies during use. When the cable is bent, the hard shell protection seat will form a certain resistance to the cable, and can resist the bending force to a certain extent when the cable is bent. This resistance may also have a certain impact on the cable. The hard shell protection seat may limit the bending radius of the cable. If the cable needs to be bent frequently or the bending angle is large, the hard shell protection seat may have an adverse impact on the bending performance of the cable, resulting in problems such as premature fatigue fracture of the cable. When the cable is bent, the hard shell protection seat may cause excessive stress concentration on the cable, resulting in the core wire inside the cable being squeezed or rubbed, thereby affecting the transmission performance and service life of the cable. For this reason, we provide a cable silicone plug. Summary of the Utility Model

[0005] The utility model provides a cable silicone plug to solve the technical problems existing in the above background art.

[0006] The purpose and effect of a cable silicone plug of the utility model are achieved by the following specific technical means: A cable silicone plug includes a protective shell. A sealing component is arranged at the top end of the protective shell. A connecting component is arranged at the bottom end of the protective shell. Two anti-friction components are arranged inside the protective shell. Each anti-friction component includes a telescopic pad arranged inside the protective shell. An annular shell is fixedly connected to the outer surface of each telescopic pad. A silicone sleeve is fixedly connected to the inner wall of the protective shell.

[0007] The closed component includes an annular groove formed on the upper surface of the protective shell. The inner wall of the annular groove is clamped with an annular plate, and the upper surface of the annular plate is fixedly connected with a telescopic sleeve.

[0008] The connection component includes a connecting cylinder. The upper surface of the connecting cylinder is connected to the bottom surface of the protective shell, and two annular snap rings are fixedly connected to the outer surface of the connecting cylinder.

[0009] A set of springs is fixedly connected to the outer surface of each annular shell, and one end of each set of springs away from the annular shell is connected to the inner wall of the protective shell.

[0010] Each anti-friction component includes a set of struts fixedly connected to the outer surface of the annular shell, and a baffle is fixedly connected to one end of each strut away from the annular shell.

[0011] The two anti-friction components are symmetrically arranged, and the two anti-friction components are respectively located above and below the silica gel sleeve.

[0012] Beneficial effects:

[0013] Through the cooperation of the protective shell, the closed component and the connection component, the protective shell can protect the silica gel sleeve, and the closed component can seal the protective shell, achieving the effect of waterproof and dustproof. Then, the connection component facilitates the installation of the protective shell by the staff. Through the anti-friction component provided, the position of the cable can be stabilized. When the cable is bent, it can prevent friction and avoid fatigue fracture, ensuring the transmission effect and service life.

[0014] Through the cooperation of the telescopic pad, the annular shell, the spring, the strut and the baffle, the telescopic pad can prevent contact friction between the cable and the annular shell. When the cable is bent, it will drive the annular shell to squeeze the spring. At the same time, the contraction of the spring will also exert a reaction force on the annular shell. When the annular shell drives the strut to move, the protective shell will resist the baffle, which can limit the position of the cable, prevent friction, avoid premature fatigue fracture of the cable, and ensure the transmission performance and service life of the cable. Through the cooperation of the annular groove, the annular plate and the telescopic sleeve, the telescopic sleeve can penetrate the cable and closely fit with the outside of the cable. Then, by clamping the annular plate into the annular groove, the telescopic sleeve can be fixed, thus achieving the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown in the attached Figure 1 to the attached Figure 4 As shown: A cable silicone plug includes a protective shell 1. A closed component 2 is provided at the top end of the protective shell 1. The closed component 2 includes an annular groove 201 opened on the upper surface of the protective shell 1. An annular plate 202 is clamped on the inner wall of the annular groove 201. The upper surface of the annular plate 202 is fixedly connected with a telescopic sleeve 203. By using the telescopic property of the telescopic sleeve 203, it can be closely attached to the outside of the cable. Then, through the clamping of the annular plate 202 and the annular groove 201, the sealing of the top of the protective shell 1 is formed.

[0023] A connection component 3 is provided at the bottom end of the protective shell 1. The connection component 3 includes a connection cylinder 301. The upper surface of the connection cylinder 301 is connected to the bottom surface of the protective shell 1. Two annular snap rings 302 are fixedly connected to the outer surface of the connection cylinder 301. The connection cylinder 301 facilitates the staff to splice the bottom of the protective shell 1, and the annular snap rings 302 outside the protective shell 1 can enhance the stability of the connection between the connection cylinder 301 and the device.

[0024] There are two anti-friction components 4 arranged inside the protective shell 1. Each anti-friction component 4 includes a telescopic pad 401 arranged inside the protective shell 1. The outer surface of each telescopic pad 401 is fixedly connected with an annular shell 402. The length of the telescopic pad 401 is greater than the length of the annular shell 402. The telescopic pad 401 extends above the annular shell 402 and a part below the annular shell 402, which can avoid the contact friction between the cable and the annular shell 402.

[0025] A set of springs 403 are fixedly connected to the outer surface of each annular shell 402. One end of each set of springs 403 away from the annular shell 402 is connected to the inner wall of the protective shell 1. The number of each set of springs 403 is six. When the annular shell 402 tilts to any side, the spring 403 will hold the annular shell 402.

[0026] Each anti-friction component 4 includes a set of struts 404 fixedly connected to the outer surface of the annular shell 402. One end of each strut 404 away from the annular shell 402 is fixedly connected with a baffle 405. The number of each set of struts 404 and each set of baffles 405 is six. And each baffle 405 is arc-shaped and is adapted to the inner angle of the protective shell 1. When the annular shell 402 offsets, the baffle 405 will contact the protective shell 1, thereby restricting the moving position of the annular shell 402.

[0027] The inner wall of the protective shell 1 is fixedly connected with a silica gel sleeve 5. The two anti-friction components 4 are symmetrically arranged. The two anti-friction components 4 are respectively located above and below the silica gel sleeve 5. The silica gel sleeve 5 is made of silica gel material and can protect the cable. The silica gel sleeve 5 is located between the two anti-friction components 4 and can further protect the cable, effectively preventing the cable from being damaged by friction.

[0028] Working principle: When in use, first pass the cable through the inside of the telescopic sleeve 203. The telescopic sleeve 203 will closely fit with the outside of the cable. Then pass the cable out through the top telescopic pad 401, pull the cable through the silica gel sleeve 5 and the bottom telescopic pad 401, and the cable will be stable inside the protective shell 1. Then connect the annular plate 202 with the annular groove 201, so as to form a seal at the top of the protective shell 1. When the cable is bent, the cable will squeeze the telescopic pad 401, thereby pulling the annular shell 402. The annular shell 402 will squeeze the spring 403 on the bent side of the cable. The spring 403 will contract and generate a reaction force, which can exert a reaction force on the annular shell 402, thereby preventing the cable from frictionally contacting the protective shell 1, avoiding premature fatigue fracture of the cable, and preventing the wire core from being squeezed and rubbed, ensuring the transmission performance and service life of the cable.
