Description

Technical Field

[0001] This utility model relates to the field of cable accessories technology, specifically to a cable terminal block. Background Technology

[0002] Currently, terminals are widely used in power systems as key connection components between cables and power equipment. This process involves meticulous operation: first, the insulation layer at the cable end must be precisely stripped to ensure the wire core is exposed and undamaged; then, the exposed wire core is precisely inserted into the designed terminal lug, and a stable and reliable electrical connection is achieved through crimping, welding, or fastening to ensure the safety and efficiency of power transmission.

[0003] Currently, in some electrical connection operations, after the terminal lugs are joined to the cable, workers still need to manually operate hydraulic clamps to tighten the lugs and secure the connection of the wire cores. However, this step not only causes inconvenience to the operators, but its tediousness is also obvious. The handling and precise operation requirements of the hydraulic clamps undoubtedly increase the complexity of the on-site work, prolong the operation time, and increase the overall cost. Utility Model Content

[0004] The purpose of this invention is to provide a cable terminal block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable terminal block, including a connecting shell, and further comprising: a connecting end fixed on one side of the surface of the connecting shell, an observation port opened on the surface of the connecting shell, connecting blocks fixed on both sides of the inner cavity of the connecting shell, a pressing block fixed on the surface of the connecting block, a pressing mechanism for pressing the pressing block provided in the inner cavity of the connecting shell, and a tightening mechanism for driving the pressing mechanism to work provided on the surface of the pressing mechanism.

[0006] Preferably, a heat shrink tubing is provided on one side of the surface of the connecting shell, and the heat shrink tubing is tapered.

[0007] Preferably, the extrusion mechanism includes a rotating block that rotates on the surface of the connecting shell. Metal wires are fixed on both sides of the surface of the rotating block. The metal wires pass around the surface of the extrusion block, and a fixed end is fixed at the other end of the metal wires. The other end of the fixed end is fixed to the inner cavity of the connecting shell.

[0008] Preferably, a twisting block is provided on one side of the surface of the rotating block, and the twisting block is hexagonal in shape.

[0009] Preferably, the tightening mechanism includes a driven tooth, a limiting block, a driving tooth, a base, a rotating rod, and a connecting rod. The driven tooth is fixed to the surface of the rotating block, the limiting block is fixed to the surface of the connecting shell, the base rotates on the surface of the limiting block, the driving tooth is fixed to the surface of the base, the connecting rod is fixed to one side of the surface of the driving tooth, and the rotating rod is fixed to one end of the connecting rod in a circular array.

[0010] Preferably, the size of the active tooth is larger than that of the driven tooth.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When this utility model is in use, after the inner core of the cable is connected between the two pressing blocks, the pressing mechanism can press the two pressing blocks under the action of the pressing mechanism, causing the pressing blocks to deform. Thus, the inner core of the cable can be fixed under the action of the two pressing blocks. In addition, the pressing mechanism can be assisted by the tightening mechanism to improve the practicality of the device. Attached Figure Description

Detailed Implementation

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Please see Figure 1-4As shown, a cable terminal includes a connecting shell 1, a connecting end 2 fixed on one side of the surface of the connecting shell 1, an observation port 4 opened on the surface of the connecting shell 1, connecting blocks 5 fixed on both sides of the inner cavity of the connecting shell 1, a pressing block 6 fixed on the surface of the connecting block 5, a pressing mechanism 7 for pressing the pressing block 6 in the inner cavity of the connecting shell 1, and a tightening mechanism 8 for driving the pressing mechanism 7 to work on the surface of the pressing mechanism 7.

[0020] When this utility model is in use, after the inner core of the cable is connected between the two pressing blocks 6, the pressing mechanism 7 can press the two pressing blocks 6 to deform them, thereby fixing the inner core of the cable under the action of the two pressing blocks 6. In addition, the tightening mechanism 8 can assist the pressing mechanism 7 in working, improving the practicality of this device.

[0021] A heat shrink tube 3 is provided on one side of the surface of the connecting shell 1. The heat shrink tube 3 is tapered. In this embodiment, the heat shrink tube 3 can guide the core of the cable, and the connection between the connecting shell 1 and the cable can be strengthened after the heat shrink tube 3 is heated.

[0022] The extrusion mechanism 7 includes a rotating block 71 that rotates on the surface of the connecting shell 1. Metal wires 72 are fixed on both sides of the surface of the rotating block 71. The metal wires 72 pass around the surface of the extrusion block 6. The other end of the metal wires 72 is fixed with a fixed end 73. The other end of the fixed end 73 is fixed to the inner cavity of the connecting shell 1. In this embodiment, by setting up the rotating block 71, the metal wires 72 and the fixed end 73, when the rotating block 71 rotates, the metal wires 72 on both sides can be wrapped around each other. Under the limitation of the fixed end 73, the metal wires 72 on both sides gradually extrude the extrusion block 6, so that the extrusion block 6 is deformed under the action of the connecting block 5, thereby pressing and fixing the cable core with the extrusion blocks 6 on both sides.

[0023] A screw block 9 is provided on one side of the surface of the rotating block 71. The screw block 9 is hexagonal in shape. In this embodiment, the screw block 9 makes it easier for workers to use tools to rotate the rotating block 71, thus improving the practicality of the device.

[0024] The tightening mechanism 8 includes a driven tooth 81, a limiting block 82, a driving tooth 83, a base 84, a rotating rod 85, and a connecting rod 86. The driven tooth 81 is fixed to the surface of the rotating block 71, the limiting block 82 is fixed to the surface of the connecting shell 1, the base 84 rotates on the surface of the limiting block 82, the driving tooth 83 is fixed to the surface of the base 84, the connecting rod 86 is fixed to one side of the surface of the driving tooth 83, and the rotating rod 85 is fixed to one end of the connecting rod 86 in a circular array. In this embodiment, by setting the driven tooth 81, the limiting block 82, the driving tooth 83, the base 84, the rotating rod 85, and the connecting rod 86, the height and position of the base 84 and the driving tooth 83 can be limited under the action of the limiting block 82, thereby causing the driving tooth 83 and the driven tooth 81 to mesh. Under the action of the rotating rod 85, the connecting rod 86 drives the driving tooth 83 and the driven tooth 81 to rotate, thereby enabling the extrusion mechanism 7 to work.

[0025] The size of the active tooth 83 is larger than that of the driven tooth 81. In this embodiment, this arrangement facilitates the meshing of the active tooth 83 and the driven tooth 81, achieving a labor-saving effect.

[0026] Working principle: When connecting one end of the cable, the operator first removes the insulation from one end of the cable to expose the inner core. Then, the inner core is inserted into the heat shrink tubing 3, allowing it to pass between the two compression blocks 6. After this process, the operator uses the compression mechanism 7. Under the action of the rotating block 71, the metal wire 72 rotates. With the cooperation of the metal wire 72 and the fixed end 73, the two metal wires 72 intertwine, thus compressing both sides. The compression block 6 is squeezed, causing the compression block 6 to deform. Through the mutual compression of the two compression blocks 6, the inner core of the cable can be fixed. In addition, the operator can use the tightening mechanism 8 to make the compression mechanism 7 work. Under the action of the rotating rod 85, the connecting rod 86 drives the active tooth 83 and the driven tooth 81 to mesh, thereby making the compression mechanism 7 work. It is worth noting that the tightening mechanism 8 in this application is movable. After the cable and the connecting shell 1 are connected, the tightening mechanism 8 can be used for the next cable connection work.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
