Abstract
The utility model discloses a rated current divider, which comprises a sampling resistance sheet, a left electric conducting sheet positioned at the left end of the sampling resistance sheet, and a right electric conducting sheet positioned at the right end of the sampling resistance sheet. The rated current divider is characterized in that a groove is respectively formed on the front end and the rear end of the sampling resistance sheet and at least one notch is formed on the bottom of one groove. The rated current divider is convenient in detection and has a small detection error before leaving a factory, so that higher precision of an outgoing product is guaranteed.
Description
Technical field
The utility model belongs to shunting device structure-design technique field, is specifically related to a kind of definite value shunt.
Background technology
Shunt is that the principle that produces voltage according to DC current during through resistance at the resistance two ends is processed.Shunt is widely used in and enlarges the instrument measurement range of current, and fixed definite value shunt and Precise Alloy resistor are arranged, and current limliting is done in the loops such as power supply that all can be used for communication system, complete electronic set, robotization control, and the current-sharing sampling detects.When DC current passes through, produce pressure drop, supply DC ammeter to show.Whether qualified definite value shunt (so-called qualified be that the actual resistance of definite value shunt equates with rated value of resistance perhaps in the error allowed band) directly have influence on measurement result; Therefore; Each product all will detect the resistance value of sample resistance sheet before dispatching from the factory, and product is specification product to guarantee to dispatch from the factory; And the testing of the definite value shunt resistance on the existing market is comparatively loaded down with trivial details and detect data itself just existence than mistake, thereby " specification product " that cause dispatching from the factory but not real qualified.
The utility model content
To the above-mentioned deficiency that prior art exists, the utility model provides a kind of definite value shunt, before the definite value shunt of this kind structure dispatches from the factory testing convenient and to detect error little, thereby the product that guarantees to dispatch from the factory has higher precision.
The technical scheme that realizes the utility model purpose is:
A kind of definite value shunt, the right conducting strip that comprises the sample resistance sheet, is positioned at the left conducting strip of sample resistance sheet left end and is positioned at sample resistance sheet right-hand member; The rear and front end of said sample resistance sheet respectively is provided with a groove; The bottom of a groove is provided with at least one short slot therein.
In the technique scheme, the cross sectional shape of said short slot is a rectangle.
In the technique scheme, on said left conducting strip and right conducting strip, respectively be provided with a binding post.
In the technique scheme, said binding post is for being screwed onto the screw on left conducting strip and the right conducting strip respectively.
In the technique scheme, be equipped with pilot hole on said left conducting strip and the right conducting strip.
In the technique scheme, said pilot hole is a manhole.
In the technique scheme, the plate body between two grooves of said sample resistance sheet is provided with rectangular through-hole.
In the technique scheme, said left conducting strip and right conducting strip are red copper conducting strip or brass conductive sheet, and said sample resistance sheet is the copper-manganese resistor disc.
The good effect that the utlity model has is:
Definite value shunt in the utility model respectively is provided with a groove through the rear and front end at said sample resistance sheet; The bottom of a groove is provided with at least one short slot therein; Through the resistance value that short slot detects the sample resistance sheet of definite value shunt is set; The definite value shunt that surpasses rated value of resistance for actual resistance can promptly dwindle the sample resistance sheet through the degree of depth that will increase groove and overcome; Testing is convenient and error is little, thereby the product that guarantees to dispatch from the factory has higher precision.
