Utility model content
This utility model is for header box upper connecting terminal in prior art and fuse separately distribution, cause the technical problem that distribution box space availability ratio is low, a kind of binding post with fuse is provided, on the premise of ensureing security performance, improves the space availability ratio of distribution box.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: the binding post of band fuse, including terminal block, input terminal and the left and right sides being arranged on terminal block of outlet terminal symmetry, it is characterized in that the quantity of described input terminal and outlet terminal is two right, in the middle part of described terminal block dismountable equipped with carry melt, a pair input terminal and outlet terminal are connected by the copper bar within terminal block, and input terminal and outlet terminal are connected by another by carrying the fuse element on melt.
Further, two pairs of input terminals and the trapezoidal formula of outlet terminal are distributed up and down, under a pair input terminal and outlet terminal connected by copper bar, connected by fuse element at a pair upper input terminal and outlet terminal.
Further, two melt intermediate plates are set between the input terminal and the outlet terminal that are connected with described fuse element, melt intermediate plate near input terminal is connected with input terminal, melt intermediate plate near outlet terminal is connected with outlet terminal, and described fuse element is clamped between two melt intermediate plates and input terminal and outlet terminal is connected.
Further, described carrying has the vestibule for placing fuse element on melt, and the space between described vestibule and two melt intermediate plates is corresponding, and when making load melt be arranged on terminal block, fuse element is clamped between two fusing intermediate plates.
Further, described load melt is connected or plug-in connection for being threaded into formula with terminal block.
The beneficial effects of the utility model are:
nullTwo are arranged to input terminal and outlet terminal in terminal block，One pair of which input terminal and outlet terminal are connected by copper bar，Input terminal and outlet terminal are connected by another by fuse element，Input terminal and outlet terminal through copper bar connection form binding post，Input terminal and outlet terminal through fuse element connection form fuse，Will a binding post and a fuse be arranged in a terminal block，And the circuit of fuse is completely separable with the circuit of binding post，Ensure safety during wiring，Connect during header box same as the prior art，The negative pole of header box is connected fuse inlet wire，Positive pole connects the inlet wire of binding post，The structure arranged apart relative to the fuse on header box in prior art and binding post，This utility model is effectively reduced taking up room of fuse and binding post，Improve the space availability ratio of distribution box.
Accompanying drawing explanation
