Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a mechanical high-voltage switchgear with optimized line connection reliability. Background Technology

[0002] Electrical switchgear is widely used in industrial, fire protection, and power systems. Electronic components are installed in electrical switchgear to protect them. A large number of connecting wires are used during the installation of electronic components. In order to make the wiring neat and to ensure a reliable connection between the wiring and the electrical components, wiring fixing devices are usually used.

[0003] However, in the existing technology, most electrical switch cabinet wiring fixing devices adopt a bundling method, which results in poor wiring fixing effect, easy entanglement between wires, and affects the safety of electrical components. Moreover, bundling multiple wires together is not conducive to later inspection and maintenance of the wiring. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a mechanical high-voltage switchgear with optimized line connection reliability.

[0005] The technical solution of this utility model is as follows: a mechanical high-voltage switchgear with optimized line connection reliability, including a cabinet body, a pull-out plate that slides and snaps into the cabinet body, and a limiting component set on the pull-out plate; a cabinet door is movably hinged to the front end of the cabinet body; There are two pull-out panels, which are arranged parallel to each other inside the cabinet. The two pull-out panels are slidably engaged inside the cabinet via guide rails. Several mounting holes are evenly distributed on the upper surface of the two pull-out panels. The limiting assembly includes a lower limit seat fixedly mounted on the upper surface of the pull-out panel and an upper limit seat movably hinged above the lower limit seat; a clamping screw that can be threadedly connected to the lower limit seat is rotatably engaged on the upper limit seat; an array of limiting slots are symmetrically arranged on the opposite side of the upper and lower limit seats; and a terminal block is provided at the rear end of the cabinet at a position corresponding to each limiting slot.

[0006] Furthermore, the cabinet is equipped with a linkage assembly that connects to the pull-out panel. The linkage assembly includes a support rod that is rotatably engaged with the rear end of the cabinet and a linkage rod that is movably hinged between the support rod and the pull-out panel. The two ends of the support rod are respectively rotatably engaged with sliders that are slidably engaged with the inner wall of the cabinet. The two sides of the cabinet side wall are respectively equipped with guide rods that are slidably engaged with the two sliders one by one. Each of the two guide rods is fitted with a damping spring that abuts against the bottom surface of the slider at the corresponding position. Note: After the electrical switch is connected to the terminal block by a wire, the support rod moves upward along the guide rod under the action of the damping spring, so that the wire is always taut and the wires on different electrical switches are not tangled together, which would affect the safety of the electrical switch. When the pull-out panel is pulled out of the cabinet, the linkage rod pulls the support rod downward along the guide rod.

[0007] Furthermore, several partition plates are evenly distributed on the strut; Explanation: The separator is used to separate the wires on different electrical switches, thus preventing safety accidents caused by friction between the wires on different electrical switches.

[0008] Furthermore, a rubber buffer block is installed at the rear end of the cabinet interior, corresponding to the position of the pull-out panel; Note: When the pull-out panel moves along the guide rail into the cabinet under the action of the damping spring, the rubber buffer block can buffer the impact of the pull-out panel on the cabinet.

[0009] Furthermore, positioning blocks are slidably engaged on both sides of the pull-out plate near the linkage component; Note: After the pull-out panel is pulled out of the cabinet, the positioning blocks are used to lock the pull-out panel to the outer wall of the cabinet, thereby providing a stable and reliable installation environment for electrical switches.

[0010] Furthermore, a junction box located outside the terminal block is movably hinged at the rear end of the cabinet; Note: Junction boxes can isolate terminals from the external environment, preventing them from being corroded by moisture and improving their reliability.

[0011] Furthermore, the lower limit seat is provided with an arc-shaped push plate inside the limit slot at the corresponding position. The arc-shaped push plate is movably connected to the lower limit seat through a plug rod. The lower limit seat is provided with a compression spring that abuts against the plug rod. Note: When the lower limit seat and the upper limit seat are engaged, the arc-shaped push plate, under the action of the compression spring, always presses the connecting wire inside the limit slot, so that this utility model can limit and fix the connecting guides of different diameters.

[0012] The working principle of this utility model is as follows: In use, install and fix the electrical switch (commercially available product) to the mounting holes on the pull-out plate using bolts. Then, connect one end of the connecting wire to the corresponding terminal block, and connect the other end of the connecting wire through the support rod and the limit slot to the electrical switch. Then, use the clamping screw to fix the upper limit seat and the lower limit seat. When the upper limit seat is close to the lower limit seat, it limits and fixes the connecting wire. At this time, the support rod moves upward along the guide rod under the action of the damping spring, so that the connecting wire is always in a taut state. Then, connect the outer end of the terminal block to the external power supply line. When it is necessary to replace the electrical switch, pull the pull-out plate out of the cabinet. At this time, the linkage rod pulls the support rod downward along the guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects: First, the structure of this utility model is reasonably designed. It uses the upper limit seat and the lower limit seat to limit and fix the connecting wire, which prevents the connecting wire from being pulled off during the movement of the electrical switch, and helps to improve the connection reliability between the electrical switch and the connecting wire. Secondly, this utility model utilizes a support rod that can move up and down inside the cabinet to provide movable support for the connecting wires, so that the connecting wires are always taut, avoiding the tangling of connecting wires on different electrical switches, thereby improving the safety of using the electrical switches. Third, this utility model provides an arc-shaped push plate inside the limiting slot on the lower limiting seat. When the lower limiting seat and the upper limiting seat are engaged, the arc-shaped push plate presses the connecting wire inside the limiting slot under the action of the compression spring, so that this utility model can limit and fix the connecting guides of different diameters.
