Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a cable joint butt protection structure for electric power supply. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly used for control installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. Since cables are charged, installation requires special care. When connecting two cables, a docking protection mechanism is required to connect them to avoid damage.

[0003] For example, the authorization announcement number is "CN219329423U", which is a cable connector docking protection structure for electric power supply. When the cable is pulled by the outside world during use, the cable can use the cooperation of the winding rod and the spring to make the cable in the protective shell play a certain buffering role when it extends outward, thereby avoiding the problem of directly pulling the cable and causing the cable connector to break. However, when one end of the cable is pulled, the cable connector docking protection structure for electric power supply will tilt to one side because the protective shell is not fixed, which causes the cable connector to break from one side, thereby reducing the working quality of the cable connector docking protection mechanism. At the same time, when the protective shell of the cable connector docking protection structure for electric power supply is opened, the operator needs to use bolts to disassemble the cover plate, which increases the workload of the operator. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when one end of the cable is pulled, the protective shell is not fixed and thus tilts to one side, which causes the cable joint to break from one side, thereby reducing the working quality of the cable joint docking protection mechanism and requiring the operator to use bolts to disassemble the cover plate when the protective shell is opened, which increases the workload of the operator. A cable joint docking protection structure for electric power supply is proposed to solve the problem.

[0012] The utility model proposes a cable joint butt protection structure for electric power supply, which has the beneficial effect that: through the cooperation of the shell and the cable joint fixing mechanism, the knob drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the double-headed stud to rotate, the double-headed stud drives the clamping plate to move, and the clamping plate clamps the cable joint. The above method can avoid cracking of the cable joint, which improves the working quality of the cable joint butt protection structure.

[0013] Through the cooperation of the shell and the transparent plate moving mechanism, the pull block drives the pull rod to move, and the pull rod drives the first spring to compress and drives the clamping block away from the shell. Then the operator pushes the slider, and the slider drives the transparent plate to move. After the transparent plate is moved away from the shell, the first spring drives the clamping block to reset, so that the clamping block presses against the shell to prevent the transparent plate from moving. The above method can make it more convenient for the operator to open the shell, which reduces the workload of the operator. BRIEF DESCRIPTION OF THE DRAWINGS
