Summary of the invention
This utility model provides a kind of built-in lightning-protection module advanced for instrument, to solve to propose in above-mentioned background technology Problem.
This utility model is solved the technical problem that and is realized by the following technical solutions: this utility model provides one For the built-in lightning-protection module that instrument is advanced, including module body, described module body is cylindrical-shaped structure, by main body and the end Seat grafting forms, and the top of main body is plugged with the attaching plug for connecting power line, and the bottom of main body is provided with boss, boss Bottom be provided with ground pin, the top of base is provided with the groove matched with described boss, and connects with described The grounding receptacle that ground plug matches, described grounding receptacle is provided with first annular groove and the second cannelure, two annulars Being inlaid with the first copper ring and the second copper ring in groove respectively, two copper rings are connected to the first ground copper and the second grounding copper Sheet, the first ground copper and the second ground copper are drawn from the bottom of base, are filled with insulation pottery in the housing of described base Porcelain.
The both sides of described boss are machined with one group of plane being parallel to each other, and main body is plugged on base by above-mentioned plane On.The through hole for module body being fixed on instrument housing it is provided with in described main body and base.
The beneficial effects of the utility model are:
1, this utility model is by being optimized design to the structure of existing lightning-protection module, especially module body is set It is set to cylindric, only existing instrument housing need to be lengthened, module body can be placed in the instrument of tubular structure smoothly In table, compared with prior art, lightning-protection module is become built-in from external, and lightning-protection module is hardly damaged;When manufacturing instrument, Ke Yifang Just quickly this utility model is arranged in instrument, when instrument is installed, only needs once mounting just to can reach lightning protection purpose, install Convenient, construction cost is low.
2, this utility model arrange two copper rings and two ground coppers, it is provided that two independent grounded circuits, make The reliability obtaining lightning protection increases further.
3, ground pin and grounding receptacle are separately positioned on main body and base, and ground pin and grounding receptacle grafting coordinate After play the role of positioning, it is ensured that the accurate positioning between main body and base is errorless.
4, the plane of the both sides processing of boss, can prevent from relatively rotating between main body and base, so that the two it Between connection more firm.
5, power line is connected in main body by attaching plug so that connects power line and is to protect against wiring, thus improves Efficiency of assembling.
6, it is provided with through hole on main body and base, for module body is fixed on instrument housing, it is ensured that module Being stably connected with between body and instrument housing.
7, the contact of ground pin and grounding receptacle uses copper ring structure, compared with existing copper sheet contact, connecing of contact Contacting surface is long-pending bigger, is electrically connected more reliable.
