Description
[technical field]
The utility model relates to a kind of short connector, especially relates to a kind of signal school line short connector.
[background technology]
When the line operation of signal school is carried out to electrical equipment, intercepting one section of electric wire is conventional way as short connector, direct electric wire short circuit needs the terminal of short circuit, earth terminal or holding wire core, easily occur that electric wire grips inconvenience and causes electric wire to grip the drawbacks such as unstable, electric wire easily occurs when gripping unstable missing the situations such as short circuit voltage dropping element, operator's personal injury may be caused, when carrying out the core short circuit of on-the-spot table meter, as carried out having a power failure and insulating wrapping when holding wire carries dangerous voltage, but often there is when operating the situation that holding wire cannot have a power failure.
[summary of the invention]
In order to overcome the deficiency in background technology; the utility model discloses a kind of signal school line short connector; by arranging fuse in master meter pen inside; protruding ring is set in major-minor test pencil front end, blocks finger, prevent operator from getting an electric shock; when needs accommodate unfixed core and other signaling point; chuck can be connected with plug, play fixation with chuck, keep the scene intact when reaching operator's field operation mistake short circuit voltage dropping element the object of operator from flash burn.
In order to realize described goal of the invention, the utility model adopts following technical scheme:
A kind of signal school line short connector, comprise chuck, master meter pen, subtabulation pen and line, described chuck comprises crocodile clip, socket is provided with in the lower end of crocodile clip, the jack of opening in lower end is provided with in socket, plug is respectively equipped with in the upper end of master meter pen and subtabulation pen, protruding ring is respectively equipped with on the outer edge surface top of master meter pen and subtabulation pen, groove is provided with in the bottom of master meter pen, the two ends of described line connect the lower end of master meter pen and the lower end of subtabulation pen respectively, described chuck is two, and two chucks connect two plugs respectively.
Described signal school line short connector, is covered with insulating sleeve in the outside of crocodile clip.
Described signal school line short connector, is provided with fuse in groove.
Described signal school line short connector, is covered with fuse protection cover at groove mouth.
Owing to have employed technique scheme, the utility model has following beneficial effect:
Signal school described in the utility model line short connector, by the test pencil design adopting universal instrument popular in master meter pen and subtabulation pen, in master meter pen inside, fuse is set, whether the convenient fuse of observing of transparent mode fuse protection cover fuses, in major-minor test pencil front end, protruding ring is set, block finger, prevent operator from getting an electric shock, when needs accommodate unfixed core and other signaling point, chuck can be connected with plug, play fixation with chuck, keep the scene intact when reaching operator's field operation mistake short circuit voltage dropping element the object of operator from flash burn; The utility model structure is simple, applied widely, easy to use, wide market.
