Description
Technical Field
The utility model belongs to the technical field of high-low voltage switch cabinet assembly process equipment, especially, relate to a signal fuse base in auxiliary circuit in low-voltage switch cabinet.
Background
In a low-voltage switch cabinet, a signal fuse is generally connected in parallel below fixing screws of cover plates at two ends of a main circuit fuse link, when the main circuit fuse link is fused, a signal fuse fusing impact body acts immediately to eject a striker to push a microswitch to send a signal or automatically switch a circuit. Conventional signal fuse base selects and installs according to signal fuse's specification, and signal fuse's a great variety, and different in size selects the fuse base that different specifications just need to be disposed to different fuses, causes a great deal of inconvenience to the design of cubical switchboard and assembly, so conventional signal fuse base can't satisfy the demand of modern assembly design.

The utility model aims to improve the defects of the existing products and provide a novel universal fuse base which is convenient to install, easy to disassemble, strong in universality and interchangeability, safe, reliable and small in operating force.
The utility model aims at realizing like this, a novel universal fuse base, including insulating base and fuse, its characteristics are fixed with micro-gap switch in insulating base's one end, and the fuse one end and the micro-gap switch contact at the metal chuck are installed to two sets of metal chucks that are used for installing the fuse setting at the both ends of insulating base upper surface, and insulating base's below both ends are fixed with a connecting plate respectively.
In order to further realize the utility model discloses an aim at, can be that insulating base upper and lower surface is opened there is the constant head tank, is equipped with the guiding hole in the constant head tank, and metal chuck and connecting plate can be fixed at the guiding hole optional position.
In order to further realize the utility model discloses an aim at, can be that insulating base one end is opened there is the fixed orifices, and the fixed orifices lower part corresponds to be opened there is the hexagonal hole, and the downthehole outer hexagon nut that is equipped with of hexagonal, micro-gap switch pass through the bolt and the hexagon nut cooperation is fixed.
In order to further realize the utility model discloses a can be that the connecting plate upper end is opened has the bar hole that is arranged in according to main loop in fuse length adjusting position, and the lower extreme is opened there are spliced eye and line ball hole, and the spliced eye is used for its direct grafting on parallelly connected fuse, and the line ball hole is used for being connected to the fuse of main loop with the wire for the connecting plate on.
In order to further realize the purpose of the utility model, the microswitch is 1 normally open and 1 normally closed.
Compared with the prior art, the utility model has the advantages of obvious characteristics and positive effect: the universal fuse base is fixed at two ends of the insulating base through two groups of metal chucks and connecting plates through bolts, and has simple structure form and convenient installation and operation; the insulating base is provided with a guide hole and a positioning groove, and the metal chuck and the connecting plate can be fixed at any position in the guide hole and are suitable for installing signal fuses of various length specifications; one end of the insulating base is provided with a fixing hole, the lower part of the fixing hole is correspondingly provided with a hexagonal hole, and an external hexagonal nut is arranged in the hexagonal hole, so that the micro switch is convenient to mount and dismount and is safe and reliable; the fuse base is cast and molded by DMC material (or equivalent), the processing is convenient, the volume is small, the weight is light, and the strength is high; the metal chuck is provided with the guide arc, so that the fuse can be conveniently clamped, the installation is convenient, the disassembly is easy, the clamping force is large, and the safety and the reliability are realized; the upper end of the connecting plate is provided with a strip-shaped hole which can be assembled according to a drawing or reversely assembled, namely the connecting plate is installed by rotating 180 degrees, so that the position of the connecting plate can be adjusted according to the length of a fuse link in a main loop, the length requirements of various main loop fuses are met, the lower end of the connecting plate is provided with an inserting hole and a line pressing hole, the inserting hole is convenient for being directly inserted into the fuse link connected in parallel, the line pressing hole can realize that the connecting plate is connected onto the fuse link of the main loop by a wire, and the multi-mode connection with the main loop fuse link is realized so as to adapt to different installation; a microswitch is fixed on the insulating base, after the signal fuse is fused, the fusing impactor acts to eject the striker to push the microswitch to send a signal or automatically switch a circuit, and the microswitch is normally opened 1 and normally closed 1, so that the volume is small and the weight is light.
