[0002] After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called an intermediate joint, and the cable joints at both ends of the line are called terminal heads.

[0003] At present, in the prior art, a cable joint needs to be provided with a cable joint connector, which is also called a protective cover, for protecting the cable joint to prevent problems with the cable joint from causing interruption of the current and affecting the subsequent work process. The existing cable joint protective cover needs to be fixed with a large number of bolts when in use, which makes the installation of the cable joint connector very inconvenient. In addition, this structure often results in a relatively stable structure of the connector itself, but relative sliding may occur between the cable joint and the connector. This makes the cable structure more susceptible to damage when the cable is subjected to a strong external force, and the cable joint will still fall off. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0026] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: See Figures 1 to 3 This embodiment discloses a cable joint anti-drop-off connector, comprising a first component 1 and a second component 2 which are separately arranged, and the two components can form an anti-drop-off protection structure at the cable joint after being assembled together.

[0028] Among them, combined Figure 1 and 2 As shown, the first component 1 is composed of a cone 11 and a first flange 12, and the first flange 12 is located at one axial end of the cone 11. A first through hole a for the cable to pass through is provided inside the cone 11, and a first claw 4 is provided at one axial end of the cone 11. In this embodiment, the first claw 4 is provided on the first flange 12.

[0029] Furthermore, the middle area of ​​the cone 11 is a variable diameter structure, and the first flange 12 is located on the large diameter side of the variable diameter structure. That is to say, the cable connector is located on the large diameter side of the variable diameter structure during installation. The variable diameter structure forms an anti-outward movement structure for the cable in the axial direction. Since the outline of the cable connector after installation (whether a connector device is added or a direct twist connection) is often larger than the outline of the cable itself, if the cable is subjected to an external pulling force, the variable diameter structure can effectively prevent the cable from moving outward under the conditions of appropriate size specifications.

[0030] On the basis of the above technical solution, the cone cylinder 11 is provided with a side hole 6 on the small diameter side of the variable diameter structure. The side hole 6 radially penetrates the side wall of the cone cylinder 11, and an internal thread structure is provided on the inner wall of the side hole 6. When in use, the bolt can be threadedly connected to the side hole 6 to lock the bolt, so that the inner end of the bolt can be tightly abutted against the cable in the first through hole a to form another constraint structure.

[0031] Furthermore, a binding piece 3 is provided on the side of the cone 11 close to the second component 2, one end of the binding piece 3 is connected to the cone 11, and the other end is a free end, and the binding piece 3 can be tightly clamped on the cable connector located inside after being folded radially inward. This structure makes the installation of the first component 1 more convenient and efficient.

[0032] Among them, the connection side of the binding piece 3 is a base 31, which plays a role of fixing and pulling when the binding piece 3 is bent and deformed. A hollow portion 32 is provided in the middle of the binding piece, which makes the binding piece form a "D"-shaped structure, making its structure thinner and more flexible, and having a larger binding contact area. It should be noted that the inner wall of the binding piece 3 is an arc structure at an axial angle, which enables it to fit more closely to the clamped cable. In this embodiment, two symmetrically arranged binding pieces 3 are provided on the first flange 12, which are used to restrain and fix both sides of the cable at the same time. In other embodiments, the number of binding pieces 3 can be designed according to actual needs. In addition, an anti-slip structure, such as barbed fine lines, can be provided on the inner wall of the binding piece 3.

[0033] The first claw 4 is a strip-shaped sheet structure axially arranged relative to the cone 11. The first claw 4 is provided with a first bend 41. The first bend 41 causes the first claw 4 to undergo a structural change in the radial direction, which is conducive to improving its structural stability and will not be easily deformed. A first hook body 42 is provided at the end of the first claw 4 for connecting the second component 2.

[0034] Combination Figure 1 and Figure 3 As shown, the second component 2 includes a straight cylinder 21, and an external thread structure is provided on the outer wall of the straight cylinder 21, so that it can be connected and fixed with the external kit. A second through hole b is provided inside the straight cylinder 21 for the cable to pass through. The straight cylinder 21 is provided with a second flange 22 at one end close to the first component 1. The second flange 22 has the same structure as the first flange 12, but in the opposite direction. A second claw 5 and a restraining plate 3 are provided on the second flange 22.

[0035] The second clamping claw 5 is a strip-shaped sheet structure axially arranged relative to the straight tube 21 , and two second bends 51 are arranged on the second clamping claw 5 , which have the same effect on the first bend 41 .

[0036] The second claw 5 is provided with a second hook body 52 matched with the first hook body 42 at one end close to the first component 1 . The first hook body 42 and the second hook body 52 can be engaged with each other in the axial direction to form the engaging and limiting structure.

[0037] During installation, the first claw 4 and the second claw 5 are staggered in the radial direction relative to the first component 1, and the first claw 4 is located inside the second claw 5, the first hook body 42 is bent outward, and the second hook body 52 is bent inward. This structure prevents the hook structure from being exposed, thereby reducing safety hazards.

[0038] The second flange 22 is also provided with two symmetrically arranged binding pieces 3 for tightly connecting the cables.

[0039] In the specific implementation process, the conical cylinder 11 and the straight cylinder 21 are axially aligned, and the adjacent sides of the first claw 4 and the second claw 5 are provided with a clamping limit structure to prevent mutual axial outward movement, which is beneficial to prevent the connector from sliding relative to the cable after installation and causing the cable connector to fall off.

[0040] Example 2: Based on Example 1, Figure 4 As shown, in order to increase the structural strength of the first component 1 itself and the firmness of the connecting cable, the side wall of the cone 11 is provided with an inner folding portion 13 with a radially concave structure. In this embodiment, the two inner folding portions 13 are symmetrically arranged to form two inner concave point structures on the inner wall of the cone 11. The function of this structure is to enhance the contact friction between the first component 1 and the cable, thereby enhancing the connection stability between the two. In actual use, tools such as contact pliers can also be used to pressurize and deform the cone 11 after the cable is passed through, and the inner folding portion 13 is used to tightly connect the first component 1 and the cable.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
