[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0032] like Figures 1 to 5As shown, this utility model discloses an anti-detachment cable connector, applied to cable 4. The anti-detachment cable connector is mainly used to ensure a firm connection between cable 4 and the connector, preventing cable 4 from falling off or being damaged due to vibration, pulling, or improper operation during use. The anti-detachment cable connector includes a plug assembly 1, a fixing member 2, and a protective sleeve 3. The plug assembly 1 includes a housing 11 and a core assembly 12. The housing 11 is made of stainless steel, which has corrosion resistance, high strength, and stability. The outer side of the housing 11 has a flange structure, which can effectively connect with other components. The housing 11 is used to protect the core assembly 12. The core assembly 12 is attached to the inside of the housing 11 to ensure that it is not easily displaced. One end of the core assembly 12 is connected to the cable 4 to receive and transmit electrical signals or power. The cable 4 and the core assembly 12 can be connected by welding, crimping or plugging, etc., and can be adapted as needed. The fixing member 2 has a hollow column structure. The radial dimension of the fixing member 2 is larger than the radial dimension of the cable 4. The fixing member 2 is sleeved on the cable 4 and connected to the housing 11. The fixing member 2 is used to protect the connection part between the cable 4 and the core assembly 12, effectively preventing external pulling force and contact and wear on the connection part during use, thereby reducing the loosening or slippage of the cable 4, and thus achieving fixation and safety.

[0033] Continue to refer to Figures 1 to 5 The protective sleeve 3 is fitted onto the outer wall of the fixing member 2. The protective sleeve 3 is the external protective part of the entire anti-detachment cable connector. It can be made of a flexible and elastic material and can be adapted to the usage environment, extending along the direction of the cable 4 (e.g., Figure 1 (As shown in the y direction), the length of the protective sleeve 3 is greater than that of the fastener 2, which can expand the protection range and prevent external physical damage from causing damage to the connection between the cable 4 and the fastener 2 and the core assembly 12, as well as the connection between the fastener 2 and the core assembly 12. At the same time, the protective sleeve 3 also has the functions of waterproof, dustproof and UV protection, thereby enhancing the service life of the cable 4.

[0034] In this application, the operator first connects one end of the cable 4 to the core assembly 12 of the plug assembly 1. Then, the fixing member 2 is fitted onto the cable 4 and connected to the housing 11 of the plug assembly 1, so that the fixing member 2 serves as the first protective layer for the connection between the cable 4 and the core assembly 12. Finally, the operator fits or injection molds the protective sleeve 3 onto the fixing member 2, so that one end of the protective sleeve 3 is connected to the housing 11 and the other end is connected to the cable 4. Due to the extension direction of the cable 4 (e.g., ... Figure 1In the y-direction shown, the length of the protective sleeve 3 is greater than that of the fastener 2. Therefore, the protective sleeve 3 tightly wraps around the fastener 2, making the protective sleeve 3 a second protective layer for the connection between the cable 4 and the fastener 2 and the connection between the fastener 2 and the housing 11. Through the double protective layer, the cable 4 and the plug assembly 1 are effectively connected, thereby achieving the stability and safety of the cable 4 connection.

[0035] In some embodiments, the material of the fastener 2 can be adapted as needed. For example, the fastener 2 can be made of stainless steel. Stainless steel fasteners 2 have characteristics such as corrosion resistance, high strength, good thermal properties, and plasticity, ensuring practicality and robustness. Figure 2 and Figure 3 As shown, the fixing member 2 has a first end 21 and a second end 22. The first end 21 is connected to the housing 11 of the plug assembly 1, and the second end 22 is connected to the cable 4. The connection method between the fixing member 2 and the housing 11 can be plug-in, snap-fit, or threaded connection, etc. In one example, continue to refer to... Figure 2 and Figure 3 The fastener 2 is threadedly connected to the housing 11. The side wall of the first end 21 is provided with an internal thread 5, and one side of the housing 11 is provided with an external thread 6. The external thread 6 and the internal thread 5 are matched with each other. The threaded connection has high tensile and torsional strength, ensuring that the fastener 2 is firmly fixed in the housing 11. When subjected to external forces or vibrations, it can effectively maintain the stability of the connection and avoid poor connection due to loosening. It is also detachable, which is convenient for operators to maintain and replace. At the same time, it provides higher stability, reliability and durability for the entire anti-detachment cable connector.

[0036] In some embodiments, such as Figures 1 to 3 As shown, the inner wall of the second end 22 of the fastener 2 is provided with multiple annular protrusions 7. The second end 22 is connected to the cable 4 through the annular protrusions 7. The multiple annular protrusions 7 are along the extending direction of the fastener 2 (e.g., Figure 3 The annular protrusions 7 are spaced apart in the y-direction shown in the diagram to ensure that each annular protrusion 7 can contact the outer surface of the cable 4 at different positions and provide support. This allows the fastener 2 to be fixedly connected to the cable 4 through multiple annular protrusions 7, effectively dispersing the pressure of external forces and enhancing the stability of the connection. The number of annular protrusions 7 can be two, four, seven, etc., and can be adapted as needed. This application does not impose too many limitations on this. During installation, one end of the cable 4 passes through the second end 22 of the fastener 2. The annular protrusions 7 of the second end 22 make close contact with the outer surface of the cable 4, forming a physical locking effect, effectively restricting the position of the cable 4, thereby firmly fixing the cable 4 in the fastener 2. At the same time, the annular protrusions 7 effectively prevent the cable 4 from sliding or loosening in the second end 22 of the fastener 2, thereby ensuring the reliability of long-term use.

[0037] In some embodiments, such as Figures 1 to 3 As shown, the outer surface of the fastener 2 is provided with a plurality of through holes 23, that is, the plurality of through holes 23 are located on the outer surface near the first end 21, and the plurality of through holes 23 are arranged along the circumference of the fastener 2 (e.g., Figure 3 The through holes 23 are arranged at intervals in the H direction shown in the diagram. The shape of the through holes 23 can be circular, square, elliptical, etc. In one example, such as... Figure 3 As shown, the middle of the through hole 23 has a square structure, and both ends have an arc-shaped structure, thus providing stability and the ability to withstand greater external forces. Figure 1 , Figure 3 and Figure 5 As shown, there is a gap 8 between the cable 4 and the fixing member 2. The gap 8 is used to accommodate filler. The gap 8 is connected to the outside through the through hole 23. During the assembly process, the operator fills the gap 8 through the through hole 23 to fill and fix the connection between the cable 4 and the core assembly 12, so as to prevent the connection from breaking or loosening. It should be noted that the filler can be solid, powder or liquid glue, as long as it can wrap and fix the connection between the cable 4 and the core assembly 12. This application does not impose too many restrictions on this.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the outer surface of the fastener 2 away from the through hole 23 is a smooth surface, that is, the smooth surface is located on the outer surface near the second end 22. There is a protrusion 24 between the smooth surface and the through hole 23. The smooth surface is convenient for the operator to squeeze with a squeezing device. The protrusion 24 is used to limit the position of the squeezing device so that the second end 22 is tightly attached to the outer surface of the cable 4. In the assembled state, after the fastener 2 is sleeved on the cable 4, since the radial direction of the fastener 2 is greater than that of the cable 4, the second end 22 of the fastener 2 is in contact with the outer surface of the cable 4. However, depending on the size of the cable 4, there may be looseness and the connection is not tight. For example, when the radial dimension of the cable 4 is much different from the radial dimension of the fastener 2, the operator needs to use a squeezing device to adjust the radial dimension of the second end 22 of the fastener 2 and press it tightly towards the side with the cable 4. That is, the difference between the radial dimension of the second end 22 and the radial dimension of the cable 4 gradually decreases, so that the second end 22 is tightly attached to the outer surface of the cable 4, thereby fixing the cable 4 and preventing the cable 4 from slipping off the fastener 2 and loosening.

[0039] In some embodiments, such as Figure 1 , Figure 4 and Figure 5As shown, the protective sleeve 3 has a frustum structure. The frustum structure of the protective sleeve 3 can match both the housing 11 and the cable 4 and provide effective protection. The protective sleeve 3 has a larger end 31 and a smaller end 32. The larger end 31 is fitted onto the housing 11 and fits tightly, ensuring that the protective sleeve 3 is firmly fixed to the outside of the housing 11 of the plug assembly 1 and effectively preventing the connection between the housing 11 and the first end 21 of the fixing member 2 from being directly damaged by external forces. The smaller end 32 is fitted onto the cable 4 and fits tightly, ensuring that the protective sleeve 3 is firmly fixed to the outer surface of the cable 4, so that the connection between the cable 4 and the second end 22 of the fixing member 2 is effectively protected, thereby preventing the connection of the cable 4 from directly contacting the external environment and reducing the impact of friction, impact and pulling on the cable 4.

[0040] In some embodiments, such as Figure 5 As shown, a sealed space 9 is formed between the housing 11, the protective sleeve 3, and the cable 4. The fastener 2 is located in the sealed space 9 and fits against the protective sleeve 3, thereby effectively protecting the connection between the cable 4 and the housing 11, the connection between the cable 4 and the fastener 2, and the connection between the fastener 2 and the housing 11. This prevents harmful substances such as dust, liquids, and chemicals from entering the sealed space 9 and protects the connection from loosening due to external environmental influences, thereby improving durability and practicality.

[0041] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the protective sleeve 3 has an injection hole 33. Operators can inject adhesive into the protective sleeve 3 through the injection hole 33 to enhance the connection strength of the connecting parts. In one example, when the protective sleeve 3 and the fastener 2 are tightly fitted without gaps, the injection hole 33 is used to inject adhesive into the gap 8. That is, the operator fills the gap 8 with adhesive through the injection hole 33 and the through hole 23, so that there is no gap between the cable 4 and the core assembly 12, and the connecting part of the cable 4 and the core assembly 12 is tightly wrapped and adhered to by the adhesive, avoiding... To prevent the connection from breaking or loosening, in another example, the glue injection hole 33 is used to inject glue into the sealed space 9 to fill the sealed space and gap 8, so that there is no gap between the protective sleeve 3, the fastener 2 and the cable 4, which enhances the tightness of the connection and extends the service life. It should be noted that the glue can be adhesive, epoxy resin, polyurethane, etc., and can be adapted as needed, as long as it can fill the gap between the protective sleeve 3, the fastener 2 and the cable 4 without gaps. This application does not impose too many restrictions on this.

[0042] In some embodiments, the protective sleeve 3 is a rubber protective sleeve, which has the characteristics of elasticity, durability and adsorption, and can be tightly adsorbed onto the housing 11, the fixing member 2 and the cable 4, thereby providing all-round protection to achieve flexibility and safety.

[0043] In some embodiments, such as Figures 1 to 5 As shown, the core assembly 12 includes a core 120 with a cylindrical structure and multiple pins 121. The core 120 is connected to the housing 11, and the connection method can be adhesive, snap-fit, etc., which can be adapted as needed. This will not be elaborated further in this application. The core 120 is made of plastic, which is lightweight, has good electrical insulation, heat insulation, and corrosion resistance, effectively protecting the pins 121. One end of each pin 121 is fixed to the core 120, and the other end is electrically connected to the cable 4. The pins 121 are aligned along the axial direction of the core 120 (e.g., ...). Figure 2 As shown in the y-direction, a pinhole 122 is formed on the side of the core 120 away from the pin 121 to facilitate subsequent installation and use. The number of pins 121 can be five or seven. It should be noted that the pins 121 correspond to the pinholes 122. In this application, seven pins 121 are used, that is, the plug assembly 1 is a seven-pin plug assembly. The pins 121 and the core 120 are an integral structure, thereby ensuring the stability and practicality of the entire core assembly 12.

[0044] The working principle of the anti-detachment cable connector of this application is as follows:

[0045] like Figures 1 to 5 As shown, firstly, the operator connects one end of the cable 4 to the pin 121 of the core assembly 12, and then attaches the fixing member 2 to the cable 4 so that the first end 21 of the fixing member 2 is threadedly connected to the housing 11 of the plug assembly 1. The second end 22 of the fixing member 2 contacts and connects to the cable 4 through the annular protrusion 7. Since the radial direction of the fixing member 2 is greater than that of the cable 4, the second end 22 of the fixing member 2 contacts the outer surface of the cable 4 but is not tightly. Therefore, the operator needs to use a pressing device to adjust the radial dimension of the second end 22 and press it tightly towards the side with the cable 4. That is, the difference between the radial dimension of the second end 22 and the radial dimension of the cable 4 gradually decreases, so that the second end 22 is tightly attached to the outer surface of the cable 4, thereby fixing the cable 4 and preventing the cable 4 from slipping off and loosening from the fixing member 2. Thus, the fixing member 2 serves as the first protective layer for the connection between the cable 4 and the core assembly 12.

[0046] Afterwards, the operator attaches or injection molds the protective sleeve 3 onto the fixing component 2, so that one end of the protective sleeve 3 is connected to the housing 11, and the other end contacts and connects with the cable 4. This is because, in the extension direction of the cable 4 (e.g., ...), ... Figure 1In the y-direction shown, the length of the protective sleeve 3 is greater than the length of the fastener 2. Therefore, the fastener 2 is located inside the protective sleeve 3, and the protective sleeve 3 tightly wraps around the fastener 2, so that the protective sleeve 3 serves as a second protective layer for the connection between the cable 4 and the fastener 2, as well as the connection between the fastener 2 and the housing 11. Through the double protective layer, the stable connection between the cable 4 and the plug assembly 1 is effectively ensured.

[0047] Finally, there is a sealed space 9 between the protective sleeve 3 and the fixing member 2, and a gap 8 between the fixing member 2 and the cable 4. The operator can inject the required glue into the sealed space 9 through the glue injection hole 33 on the protective sleeve 3, and at the same time inject it into the gap 8 through the through hole 23 to fill it, so that there is no gap between the protective sleeve 3 and the fixing member 2 and between the fixing member 2 and the cable 4, thereby improving the strength of the connection part and thus realizing the stability and safety of the cable 4 connection.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
