The top planes of part body 11, pin plate 1 are connected by a connecting plate 121 with the top of lightning protection component body 11.
Setting direction using view direction in Fig. 1 as the lightning protection component with trip gear, by pin plate 12 and even
The connection structure of fishplate bar 121, can just cause pin plate 12 to be located at the lower section of 14 gravity direction of insulation barrier, be conducive to insulation barrier
14 are slided under the pulling force effect of tension spring 15.
The operation principle of the utility model:The fixing end of dropout shrapnel 13 is fixedly attached on fixing piece, then will be anti-
Thunder device body 11 is also connected on corresponding fixing piece, takes insulation barrier 14, and the square through hole 141 of insulation barrier 14 is right
Just to corresponding a certain setting position in pin plate 12, the elastic tip of dropout shrapnel 13 is pushed and with pin plate 12 square logical
Scolding tin connection is carried out in hole 141;
When scolding tin cools down, the elastic tip of dropout shrapnel 13 is with after 12 stable connection of pin plate, connection is installed by tension spring 15
Between extension board 132 and insulation barrier 14, insulation barrier 14 is stuck in scolding tin junction by square through hole 141, so that
Tension spring 15 has pulling force;
When the lightning protection component works normally, shielded circuit can be electrically connected by conductor and dropout shrapnel 13, together
When be also just electrically connected by pin plate 12 and lightning protection component body 11;
Break down when due to shielded circuit so that 11 near short circuit of lightning protection component body, lightning protection component body 11 is then
Largely fever high temperature can be produced, and high temperature scolding tin is transmitted by pin plate 12 and is gradually melted, when melting to a certain extent,
The elastic tip of dropout shrapnel 13 can pop up so that the circuit between dropout shrapnel 13 and pin plate 12 disconnects, and threads off;
Insulation barrier 14 slides under the pulling force effect of tension spring 15 at the same time, and welding plane 133 is in guide plane 131
Guiding under can smoothly skid off very much square through hole 141 so that insulation barrier 14 is obstructed between dropout shrapnel 13 and pin plate 12,
So as to ensure the normal dropout of lightning protection component, prevent to occur that showing for arc discharge occurs between scolding tin wire drawing and tin heap
As.
The operation principle of the above-mentioned lightning protection component with trip gear for being this preferred embodiment.
The lightning protection component with trip gear of this preferred embodiment between pin plate and dropout shrapnel by setting
Insulation barrier, after scolding tin thawing, controls insulation barrier barrier fully to be protected between pin plate and dropout shrapnel by tension spring
Hindered the normal dropout of lightning protection component, incomplete phenomenon of threading off can be prevented substantially, prevent from occurring when threading off scolding tin wire drawing with
And there is a phenomenon where arc discharge between tin heap;
Wherein, dropout shrapnel is arcuation, and the elastic tip of dropout shrapnel is used to be connected with pin boards solder by being bent to form
Welding plane, it is simple in structure while also by being bent to form the guide plane for guiding welding plane to skid off square through hole,
And can smoothly it be slided to by guide plane welding plane on the plate face of insulation barrier.
In conclusion although the utility model is disclosed above with preferred embodiment, above preferred embodiment is not used
To limit the utility model, those of ordinary skill in the art, without departing from the spirit and scope of the utility model, can make
It is various to change and retouch, therefore the scope of protection of the utility model is subject to the scope that claim defines.
