Meanwhile, the first dust cover 180 and the second dust cover 190 form a containing cavity, and the components such as the bonding main body 110 and the like are arranged in the containing cavity, so that dust particles can be prevented from entering, and the service life of a product is prolonged.
Third embodiment
Referring to fig. 12, the present embodiment provides a multipoint centralized grounding system 200, which includes a plurality of grounding wires 210, a fixed grounding pipe 230 and a multipoint centralized grounding apparatus 100, wherein the basic structure and principle of the multipoint centralized grounding apparatus 100 and the technical effects are the same as those of the second embodiment, and for brevity, the details of the second embodiment are referred to in the description of the present embodiment.
The multipoint centralized grounding device 100 comprises a grounding main body 110, a grounding encircling member 130 and a plurality of wiring terminals 150, wherein the grounding encircling member 130 is arranged on a grounding surface, a grounding opening 131 is formed in the grounding encircling member 130, the grounding main body 110 is detachably connected with the grounding encircling member 130, the bottom of the grounding main body 110 stretches into the grounding opening 131 and is used for being in electrical contact with the grounding surface, and the wiring terminals 150 are detachably connected to two sides of the grounding main body 110 and are in electrical contact with the grounding main body 110. The plurality of ground wires 210 are connected to the plurality of connection terminals 150 in one-to-one correspondence, and the fixed ground pipe 230 has a ground surface on which the ground strap 130 is disposed.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
