Description
Technical field
The utility model relates to and the electronic circuit association area, is specifically related to working signal earthing device under high-strength impact, vibration adverse circumstances.
Background technology
Existing earthing device is simple bolt and connects, and it is simple in structure, and is easy for installation, but comes off easily; The mode that also has the welding adopted, its sound construction, but be not easy to debugging and replacing.
The utility model content
The technical problems to be solved in the utility model is the deficiency that comes off easily or be not easy to debug and change at present most of earthing device, provide a kind of and can satisfy the specific (special) requirements of working under the adverse circumstances in high-strength impact, vibration, and the earthing device that can not have a negative impact to other dependency structure and product.
The technical solution of the utility model is as follows:
A kind of detachable anti-loose earthing device, include mount pad, it is characterized in that: the below of described mount pad is provided with grounding nut, there is grounding screw to pass described mount pad from top to bottom and extend in the described grounding nut, the bottom of described grounding screw and the end of described grounding nut have multidiameter and the step trough that cooperatively interacts respectively, are threaded engagement between described grounding screw and the described grounding nut; Described grounding screw is connected to one by clamp nut and described mount pad, has the gap between described grounding nut and the described clamp nut.
Described detachable anti-loose earthing device is characterized in that: clamp leaded inserted sheet in the gap between described grounding nut and the described clamp nut.
Described detachable anti-loose earthing device is characterized in that: be respectively equipped with several installing holes on the described mount pad.
Grounding nut one word loading hatch is applicable to universal straight screwdriver; Grounding nut hexagon nut wrench handling body can be selected the standard series of different sizes according to erection unit size and actual installation needs for use.
Principle of the present utility model is: individual parts connect as one, installing hole by erection unit, be fastenedly connected on this equipment, circuit signal ground is connected on the detachable anti-loose earthing device by the lead-in wire inserted sheet, and fastening grounding nut is installed firmly circuit signal ground lead-in wire inserted sheet.Grounding nut and grounding screw all have the step trough or the multidiameter that cooperatively interact to be prevented to come off; Grounding nut connects the fastening absent-mindedness that prevents with grounding screw by being threaded and directly processing the elastic deformation groove by machine work on grounding nut, making.
The beneficial effects of the utility model:
The utlity model has shock resistance, sealing and anti-corrosive properties, and dismounting is simple, is convenient to debugging and changes locking, anticreep.
