Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] see Figure 1~3 , in an embodiment of the present invention, a capacitor cover plate includes a cover plate body 1, an insulating plate 2, a rotary knob 7, a main push block 9 and a friction block 14. The cover plate body 1 is made of a high-temperature reinforced plastic HPT plate, and the cover plate An extension part 6 is arranged around the upper end of the board body 1, an insulating board 2 is arranged in the middle of the cover boar...

A lid plate of a capacitor cover body, Insulating plate, rotary knob, A main push block and a friction block, the cover plate body is made of high-temperature reinforced plastic HPT plate, At that periphery of the upper end of the cover plate body, An insulating plate is arranged in the middle of the cover plate main body, an explosion-proof valve is arranged at the upper end of the cover plate main body on the rear side of the insulating cover plate, conductive terminals are arranged on the left and right sides of the insulating plate, a mounting groove is arranged in the middle of the conductive terminals, the lower end of the conductive terminals is connected with a conductive core, the lower end of the conductive core penetrates the cover plate main body, and a sealing ring is sleevedon the lower part of the conductive core. As that main push block is driven down by the forward rotation rotary knob, the passive pushing block is further driven to slide outward, the friction block is tightly close to the inn wall of the housing, the cover plate body and the housing are firmly fixed, the firmness of the capacitor cover plate is improved, and the safety of the capacitor is also increased.
Description
technical field [0001] The invention relates to an electronic component accessory, in particular to a capacitor cover plate. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. Definition 1: A capacitor, as its name implies, is a 'charged container', a device that holds charges. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and are very close to each other form a capacitor. [0003] At present, most of the capacitor cover plates on the market are not well installed and easy to loosen, which is not conducive to the safety of the capacitor, and the cost performance is not high. Therefore, those skilled in the art provide a capacit...
