Abstract
The utility model discloses a wiring hammer device of a pedestal of a fuse for protecting a photovoltaic system. The wiring hammer device comprises a wire pressing hammer and a binding post, wherein each of the wire pressing hammer and the binding post is equipped with an installation hole, a wire pressing fastener for pressing a lead penetrates through the installation holes of the wire pressing hammer and the binding post, the wire pressing hammer comprises two sidewalls arranged oppositely and a connecting wall connecting the two sidewalls, the installation holes are arranged in one of the sidewalls, and the other sidewall includes an arch-shaped recessed surface which recesses towards the installation holes. The wiring hammer device of the utility model effectively prevents loosening of a bolt caused by vibration, and it is ensured that the wiring hammer device can press wires tightly.
Description
Technical field
The utility model relates to a kind of fuse mounting, and more particularly, it relates to fuse base wiring hammer device for a kind of photovoltaic system protection.
Background technology
Photovoltaic system protection comprises line ball hammer and binding post with fuse base wiring hammer device; generally be bolted line ball hammer and binding post; by tighting a bolt to compress the electric wire between binding post and line ball end face; in prior art, the line ball end face of line ball hammer is set to smooth end face; in the long-term situation about using of this design, easily because of vibrations, cause bolt looseness; directly affect contact between electric wire and circuit disconnects, cause the misunderstanding of thinking the too high fuse opening of electric current.
Utility model content
The deficiency existing for prior art; the purpose of this utility model is to provide fuse base wiring hammer device for a kind of photovoltaic system protection; by changing the line ball end face of line ball hammer; reach the shockproof function of wiring hammer device, prevent bolt and use loosening and cause the situation of the loose contact of electric wire long-term.
For achieving the above object; the utility model provides following technical scheme: fuse base wiring hammer device for a kind of photovoltaic system protection; comprise line ball hammer and binding post; described binding post and line ball hammer are bolted; described line ball hammer is set to U-shaped; U-shaped dual-side one side is provided with installing hole, and opposite side is set to arc-shaped concave, the recessed side to installing hole of described arc-shaped concave.
By adopting technique scheme; described line ball hammer and binding post are bolted; while tighting a bolt; the lug boss of bolt extruding arc-shaped concave compresses the electric wire between line ball hammer and binding post; be provided with arc-shaped concave and when photovoltaic system is protected with fuse operation vibration, play cushioning effect; prevent vibrations to be directly passed to bolt and cause bolt looseness, causing the loose contact of electric wire.
The utility model is further set to: described line ball securing member is bolt.
By adopting technique scheme, bolt is easily tightened fixedly line ball hammer and binding post by instrument, has guaranteed that bolt can fully push arc-shaped concave.
The utility model is further set to: in described arc-shaped concave, be provided with some lug bosses.
By adopting technique scheme, while further having guaranteed photovoltaic system protection with fuse operation vibration, wiring hammer can fully contact with electric wire.
The utility model is further set to: described line ball hammer adopts No. 65 manganese steel to make.
By adopting technique scheme, described No. 65 manganese steel are a kind of elastic metallic, have further played the effect of buffering, anyway bolt looseness while shaking when guaranteeing conductivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of fuse base wiring hammer device embodiment for the protection of the utility model photovoltaic system;
Fig. 2 is the line ball hammer structural representation of fuse base wiring hammer device embodiment for photovoltaic system protection.
Drawing reference numeral explanation:
1, binding post; 2, line ball hammer; 21, arc-shaped concave; 22, lug boss; 23, installing hole; 3, bolt.
Embodiment
Referring to figs. 1 through Fig. 2, the protection of the utility model photovoltaic system is described further with fuse base wiring hammer device embodiment.
Fuse base wiring hammer device for a kind of photovoltaic system protection; comprise all and hammering into shape and binding post with the line ball of installing hole; both installing holes wear and are connected with for compressing the line ball securing member of wire; it is characterized in that: described line ball hammer comprise two sidewalls that are oppositely arranged and with the connecting wall that is connected two side; the described installing hole sidewall that is placed in one; another sidewall is set to arc-shaped concave, and described arc-shaped concave is towards installing hole one side depression.
By adopting technique scheme; described line ball hammer 2 is connected by bolt 3 with binding post 1; tight a bolt 3 o'clock; the lug boss 22 of bolt 3 extruding arc-shaped concaves 21 compresses the electric wire between line ball hammer 2 and binding post 1; be provided with arc-shaped concave 21 and when photovoltaic system is protected with fuse operation vibration, play cushioning effect; prevent vibrations to be directly passed to bolt 3 and cause bolt 3 loosening, causing the loose contact of electric wire.
Described line ball securing member is bolt 3.
By adopting technique scheme, bolt 3 is easily tightened fixedly line ball hammer 2 and binding post 1 by instrument, has guaranteed that bolt 3 can fully push arc-shaped concave 21.
In described arc-shaped concave 21, be provided with some lug bosses 22.
By adopting technique scheme, while further having guaranteed photovoltaic system protection with fuse operation vibration, wiring hammer can fully contact with electric wire.
Described line ball hammer 2 adopts No. 65 manganese steel to make.
By adopting technique scheme, described No. 65 manganese steel are a kind of elastic metallic, have further played the effect of buffering when guaranteeing conductivity, anyway bolt 3 is loosening while shaking.
