Description

Technical Field

[0001] This utility model relates to the field of cable end clip technology, and in particular to a cable end clip. Background Technology

[0002] To secure and protect cables or optimize connection structures, ensure stable cable operation, extend service life, or improve overall safety, a tail clip can be used to fix the relative position of the cable to the equipment housing after the cable exits the housing. This prevents the cable from being pulled when plugging, unplugging, or moving equipment, and avoids loosening of interfaces, poor contact, or even detachment of internal solder joints.

[0003] However, current cables are composed of multiple strands of wire, and cables with different numbers of wires require different sized end clips for fixing. Therefore, it is necessary to frequently match specifications, which reduces the efficiency of end clip installation. Utility Model Content

[0004] This utility model provides a cable end clip that can be expanded by pulling the expansion shell, allowing the annular end clip expansion plate to slide out from the cavity inside the expansion shell. This increases the diameter between the expansion shell and the annular end clip expansion plate, enabling the cables composed of wires inside the expansion shell and the annular end clip expansion plate to pass through. This eliminates the need for multiple specifications of end clips, achieving a ready-to-use effect and improving the installation efficiency of end clips.

[0005] This utility model provides a cable end clip, including:

[0006] The expansion cover has two symmetrically arranged on the left and right sides. The inner side of the expansion cover has a cavity, and the two end faces of the expansion cover have waist-shaped grooves.

[0007] An annular tailplate expander, two of which are symmetrically arranged above and below, are slidably disposed inside a cavity. The cavity is configured to allow the annular tailplate expander to slide inside it, so as to change the diameter between the expansion shell and the annular tailplate expander.

[0008] A tight-shell assembly is disposed at the end of the expansion shell and the annular tailplate expansion plate. The tight-shell assembly includes symmetrically arranged arc-shaped springs. An end connector and an end plate are fixedly disposed at both ends of the arc-shaped springs, respectively. A sliding short column is fixedly disposed on the side of the end connector near the expansion shell. The sliding short column is fixedly disposed at the end of the annular tailplate expansion plate and is slidably disposed inside the waist arc groove.

[0009] In a cable end clip according to one embodiment of the present invention, the termination plate is fixedly disposed on the end face of the expansion housing, and an arc guide plate is slidably disposed on the outer side of the sliding short column, and the arc guide plate is fixedly disposed between the termination plates.

[0010] In one embodiment of the present invention, a movable slide is fixedly provided on the outer side of the other end of the expansion shell and the annular tail clip expansion plate. A guide rail shell is slidably provided on the outer side of the movable slide, and an installation ring plate is fixedly provided on the outer side of the guide rail shell. The wire and cable tail clip is fixedly connected to the equipment shell through the installation ring plate.

[0011] In a wire and cable end clip according to an embodiment of the present invention, protective pads are fixedly provided on the inner sides of both the expansion shell and the annular end clip expansion plate, and handles are fixedly provided on the outer sides of both the expansion shell and the end clip. The protective pads are made of rubber material.

[0012] In a wire and cable end clip according to an embodiment of the present invention, a stabilizing assembly is provided at the end of the expansion housing. The stabilizing assembly includes connecting guide arms arranged symmetrically at the top and bottom. A first upright plate and a second upright plate are respectively rotatably arranged at the two ends of the connecting guide arms. An elastic member is fixedly arranged on one side of the first upright plate. The elastic member is fixedly connected to the connecting guide arm. The first upright plate is fixedly arranged on the outside of the annular end clip expansion plate. The second upright plate is connected to the annular end clip expansion plate through the tail ring plate and the elastic housing.

[0013] In a wire and cable end clip according to an embodiment of the present invention, the second upright plate is fixedly disposed on the outer side of the end ring plate. Two end ring plates are symmetrically disposed above and below the end ring plate. The elastic cover is fixedly disposed between the end ring plate and the annular end clip expansion plate. The elastic cover has a notch on the outer side of the end near the annular end clip expansion plate.

[0014] In a wire and cable end clip according to an embodiment of the present invention, the elastic member is arranged in a "V" shape and is made of shape memory alloy material.

[0015] The technical solution provided in this application embodiment can include the following beneficial effects: This application designs a wire and cable tail clip. Pulling the expansion shell to both sides causes the expansion shell to expand, so that the annular tail clip expansion plate can slide out from the cavity inside the expansion shell, thereby increasing the diameter between the expansion shell and the annular tail clip expansion plate. The arc spring in the tight shell assembly provides a contraction force for the expansion shell and the annular tail clip expansion plate. In this way, the expansion shell and the annular tail clip expansion plate can pass through the cable composed of wires inside them. There is no need to equip multiple specifications of tail clips, which can achieve the effect of being ready to use and improve the installation efficiency of tail clips.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0024] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5 As shown, this application provides a cable end clip, including: an expansion housing 2, two expansion housings 2 are symmetrically arranged on the left and right, a cavity is opened on the inner side of the expansion housing 2, and an arc groove 2011 is opened on both ends of the expansion housing 2; two annular end clip expansion plates 3 are symmetrically arranged on the top and bottom, and the annular end clip expansion plates 3 are slidably arranged inside the cavity. The cavity is set to allow the annular end clip expansion plates 3 to slide inside it, so as to change the diameter between the expansion housing 2 and the annular end clip expansion plates 3. A protective pad 202 is fixedly arranged on the inner side of both the expansion housing 2 and the annular end clip expansion plates 3, and a handle 201 is fixedly arranged on the outer side of both the expansion housing 2. The protective pad 202 is made of rubber material.

[0028] After adopting the above technical solution, if more wires need to be passed through the tail clip, the handle 201 can be pulled so that the expansion housing 2 can be pulled to both sides, so that the annular tail clip expansion plate 3 can slowly slide out from the cavity inside the expansion housing 2, thereby increasing the diameter between the expansion housing 2 and the annular tail clip expansion plate 3, making it easier to pass through more wires. Moreover, it is not necessary to equip multiple specifications of tail clips for cables of different diameters, nor is it necessary to frequently match different specifications of tail clips, thus improving the installation efficiency of tail clips.

[0029] Specifically, a movable slide 102 is fixedly installed on the outer side of the other end of the expansion shell 2 and the annular tail clip expansion plate 3. A guide rail shell 101 is slidably installed on the outer side of the movable slide 102. An installation ring plate 1 is fixedly installed on the outer side of the guide rail shell 101. The wire and cable tail clip is fixedly connected to the equipment shell through the installation ring plate 1.

[0030] As the expansion housing 2 and the annular tail clip expansion plate 3 expand or contract, the movable slide 102 will slide inside the guide rail housing 101, thereby preventing the expansion housing 2 and the annular tail clip expansion plate 3 from shifting. Furthermore, the mounting ring plate 1 can be fixedly connected to the outside of the equipment by bolts. Therefore, when adjusting the diameter of the expansion housing 2 and the annular tail clip expansion plate 3, the installation position of the tail clip will not change, facilitating the passage of wires.

[0031] For example, the tight-shell assembly 4 is disposed at the end of the expansion shell 2 and the annular tail clip expansion plate 3. The tight-shell assembly 4 includes an arc spring 401 arranged symmetrically at the top and bottom. An end seat 402 and an end plate 403 are respectively fixedly disposed at both ends of the arc spring 401. A sliding short column 404 is fixedly disposed on the side of the end seat 402 near the expansion shell 2. The sliding short column 404 is fixedly disposed at the end of the annular tail clip expansion plate 3. The sliding short column 404 is slidably disposed inside the waist arc groove 2011. The end plate 403 is fixedly disposed on the end face of the expansion shell 2. A waist arc guide plate 405 is slidably disposed on the outside of the sliding short column 404. The waist arc guide plate 405 is fixedly disposed between the end plates 403.

[0032] In an optional embodiment, as the expansion housing 2 and the annular tail clamp expansion plate 3 expand and contract, the movement of the annular tail clamp expansion plate 3 will drive the sliding short column 404 to move, thereby driving the end connector 402 to move. Taking the expansion housing 2 and the annular tail clamp expansion plate 3 expansion as an example, the movement of the end connector 402 will cause the arc spring 401 to compress. At the same time, the sliding short column 404 will slide on the inner side of the waist arc guide plate 405 to guide the movement of the sliding short column 404. The elastic force of the arc spring 401 will cause the annular tail clamp expansion plate 3 to have a contraction force, so that the expanded housing 2 and the annular tail clamp expansion plate 3 can clamp and fix the wires and cables after expansion. If the wires and cables are taken out, the expanded housing 2 and the annular tail clamp expansion plate 3 can return to their original state by the rebound force of the arc spring 401, which is convenient for the next use.

[0033] For example, the end of the expansion shell 2 is provided with a stabilizing assembly 5. The stabilizing assembly 5 includes a connecting guide arm 501 arranged symmetrically at the top and bottom. The two ends of the connecting guide arm 501 are respectively rotatably provided with a first upright plate 502 and a second upright plate 503. An elastic member 504 is fixedly provided on one side of the first upright plate 502. The elastic member 504 is fixedly connected to the connecting guide arm 501. The first upright plate 502 is fixedly provided on the outside of the annular tail clip expansion plate 3. The second upright plate 503 is connected to the annular tail clip expansion plate 3 through the tail ring plate 505 and the elastic shell 506. The elastic member 504 is arranged in a "V" shape and is made of shape memory alloy material.

[0034] In an optional embodiment, as the expansion housing 2 and the annular tailplate expansion plate 3 expand, the elastic housing 506 also expands accordingly, so that the wires and cables can be tightly attached to the inner side of the tailplate 505. When the wires and cables bend and cause the elastic housing 506 to deform, the connecting arm 501 will be driven to move up and down. At the same time, the elastic member 504 will deform. Through the rebound force of the elastic member 504, the wires and cables will recover after bending, and the wires and cables that have been bent for a long time can be reset, reducing the fatigue of the wires and cables.

[0035] For example, the second upright plate 503 is fixedly disposed on the outside of the tail ring plate 505. There are two tail ring plates 505 arranged symmetrically on the top and bottom. The elastic cover 506 is fixedly disposed between the tail ring plate 505 and the annular tail clip expansion plate 3. The elastic cover 506 has a notch on the outer side of the end near the annular tail clip expansion plate 3.

[0036] In an optional embodiment, the elastic cover 506 allows the wires and cables to bend freely and prevents excessive bending, thus providing a certain degree of protection for the wires and cables. The notch is provided to prevent the elastic cover 506 from affecting the use of the tight-fitting assembly 4 when it deforms.
