Description

Technical Field

[0001] The utility model relates to the technical field of cable connection devices, and specifically, to a connection structure for cables. Background Art

[0002] After retrieval, a patent with the publication number CN221042306U discloses a connection structure for communication cables. By rotating a threaded cylinder, it moves along an external thread, and then a T-shaped block drives a connection block to move along a guiding through hole. During this process, a resisting plate is driven to deflect, so that the end of the resisting plate abuts against the outer side of the cable, achieving stable fixing and limiting, facilitating the limiting and fixing of cables with different diameters, and being convenient for actual installation and use.

[0003] Although the resisting plate in the above device is for the stable fixing and limiting of the cable, directly abutting against the outer side of the cable will cause internal damage to the cable after long-term use. The main reason is that the direct abutment of the resisting plate against the outer side of the cable will produce indentations on the cable surface, and such long-term contact will gradually damage the insulating layer or outer skin of the cable, thus increasing the risk of cable failure during use. Therefore, a connection structure for cables is needed. Summary of the Utility Model

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] A cable is a collection of conductive wires used to transmit power or electrical signals. It usually consists of multiple thin wires or one or more insulated conductors, covered with insulating materials and protective layers. The main function of a cable is to transmit power or data from one place to another while protecting the wires from external environmental influences and mechanical damage.

[0025] Although the contact plate in the existing device is used to stabilize and limit the cable, it directly contacts the outside of the cable, which may cause internal damage to the cable after long-term use. The main reason is that the direct contact of the contact plate with the outside of the cable will produce indentations on the cable surface. Such long-term contact will gradually damage the insulation layer or outer skin of the cable, thereby increasing the risk of cable failure during use. Figures 1-5 The embodiment provides a cable connection structure, including a penetration tube 1 and a cable 2 arranged inside the penetration tube 1.

[0026] refer to Figures 2-5As shown, although the contact plate in the existing device is used to stably fix and limit the cable 2, it directly contacts the outside of the cable 2, which will cause internal damage to the cable 2 after long-term use. The main reason is that the direct contact of the contact plate with the outside of the cable 2 will produce indentations on the surface of the cable 2. Such long-term contact will gradually damage the insulation layer or outer skin of the cable 2, thereby increasing the risk of failure of the cable 2 during use. In order to extend the service life and stability of the cable 2, the following settings are made. The right end of the through-tube 1 is provided with a device for fixing the cable 2. The positioning assembly 3 for limiting and fixing includes a rotary plate 31 arranged at the right end of the penetration tube 1 and three positioning plates 38 arranged inside the penetration tube 1. The side of the rotary plate 31 is fixedly connected with an inner cylinder 32 rotatably sleeved inside the penetration tube 1. The end of the inner cylinder 32 away from the rotary plate 31 is fixedly connected with a ring plate 33 rotatably connected to the inner wall of the penetration tube 1. The cable 2 is passed through the inside of the penetration tube 1. The rotary plate 31 is rotated to drive the inner cylinder 32 to rotate. The rotation of the inner cylinder 32 causes the ring plate 33 to rotate synchronously. The rotation of the ring plate 33 provides driving force for the power assembly. The side of the ring plate 33 is provided with a power assembly for driving the three positioning plates 38 to expand and contract simultaneously to limit and fix the cables 2 of different diameters. The power assembly includes three arc grooves 34 equidistantly arranged on the ring plate 33 in an annular manner. The inside of the three arc grooves 34 is provided with a sliding sleeve of a sliding rod 35. The end face of the sliding rod 35 is fixedly connected with a slider. The inner wall of the tube 1 is fixedly connected with a vertical plate 36. The vertical plate 36 is vertically provided with a sliding groove for the slider to slide on the side close to the ring plate 33. The rotation of the ring plate 33 causes the sliding rods 35 inside the three arc grooves 34 to move synchronously relative to each other, causing the slider to slide in the sliding groove. The friction between the slider and the sliding groove is relatively large, and the slider cannot slide in the sliding groove without external force. The end of the sliding rod 35 away from the slider is fixedly connected with a connecting plate 37. The positioning plate 38 is fixed at the bottom end of the connecting plate 37. The synchronous relative displacement of the sliding rod 35 causes the positioning plates 38 to move closer to each other, thereby limiting and fixing the cables 2 of different diameters, thereby facilitating actual installation and use.

[0027] refer to Figure 3As shown, a flexible cushion layer 39 is fixedly connected to the bottom of the positioning plate 38. The material of the flexible cushion layer 39 can be silicone or the like. The function of the flexible cushion layer 39 in the fixed connection at the bottom of the positioning plate 38 is to provide better adaptability and fixing effect, especially for cables 2 with different diameters. And the thickness of the flexible cushion layer 39 is greater than the thickness of the positioning plate 38. Due to the existence of the flexible cushion layer 39, even if the diameter of the cable 2 is different, better fixing effect can be obtained by compressing or expanding the flexible cushion layer 39. At the same time, the flexible cushion layer 39 can provide a more uniform pressure distribution, thereby enhancing the contact area and friction force between the cable 2 and the positioning plate 38, making the fixing more firm and reliable. At the same time, the flexible cushion layer 39 can reduce the risk of damage suffered by the cable 2 during the fixing process, such as scratching or extrusion deformation. It provides a certain buffering effect and reduces the influence of mechanical stress on the cable 2.

[0028] Reference Figures 2-5 As shown, an external viewing mechanism 4 for real-time temperature measurement of the surface temperature of the cable 2 is arranged inside the threading tube 1. The external viewing mechanism 4 includes a linkage plate 41 fixed to the side surface of the connecting plate 37. One end of the linkage plate 41 away from the connecting plate 37 is fixedly connected with a cable contact plate 42. A heat-conducting telescopic rod 43 is fixedly connected to the top of the cable contact plate 42. The top end of the heat-conducting telescopic rod 43 is slidably sleeved with a heat-conducting telescopic tube 44 fixed to the inner wall of the threading tube 1. The cable contact plate 42, the heat-conducting telescopic rod 43 and the heat-conducting telescopic tube 44 are all made of metal materials with high heat-conducting coefficients and can effectively conduct heat. A thermosensitive material 45 for changing color according to the change of the surface temperature of the cable 2 is coated on the top end of the heat-conducting telescopic tube 44. The cable contact plate 42 can effectively absorb the heat generated by the operation of the cable 2 by contacting the surface of the cable 2. This is because of the contact between the cable contact plate 42 and the surface of the cable 2, and the heat is absorbed into the metal structure by using the high heat-conducting property of the cable contact plate 42. The heat absorbed on the cable contact plate 42 is transmitted through the heat-conducting telescopic rod 43 and the heat-conducting telescopic tube 44. These components are made of metal materials with high heat-conducting coefficients, so the heat can be effectively transmitted from the cable contact plate 42 to the thermosensitive material 45 at the top end of the heat-conducting telescopic tube 44. The thermosensitive material 45 at the top end of the heat-conducting telescopic tube 44 is responsible for showing the transmitted heat, so that external staff can intuitively monitor the heat condition of the cable 2 system for appropriate adjustment and maintenance to ensure the safe operation of the cable 2 system.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
