Description

DC current sensor

Technical field

The utility model is related to sensor field, more particularly to a kind of DC current sensor.

Background technology

Current sensor is a kind of detection means, can experience the information of tested electric current, and can will detect the letter experienced Breath is for conversion into the electric signal for meeting certain standard needs according to certain rules or the information of other required forms exports to meet letter Transmission, processing, storage, display, record and control of breath etc. require that wherein DC current sensor is one kind therein, for example Fig. 1 senses for existing DC current, and it includes being all provided with magnetic core array 1 and lower magnetic core array 2, upper magnetic core array 1 and lower magnetic core array 2 Inner fovea part 3 is equipped with, the through hole that the formation of inner fovea part 3 passes through for wire is carried out wire to be measured through through hole during use Detection, for the ease of detecting some wires connected the line, upper one end of magnetic core array 1 is articulated with lower magnetic core array 2, and the other end leads to Bolt is crossed to fix with lower magnetic core array 2, but so when needing to open magnetic core array 1, it is necessary to bolt be pulled down, the process of dismounting It is cumbersome and efficiency is low.

Utility model content

The purpose of this utility model is to provide a kind of DC current sensor, with being easy to open the excellent of upper magnetic core array Point.

Above-mentioned technical purpose of the present utility model technical scheme is that：

On a kind of DC current sensor, including upper magnetic core array and lower magnetic core array, the upper magnetic core array and lower magnetic core array Inner fovea part is provided with, the inner fovea part formation supplies the through hole that wire passes through, and described upper magnetic core array one end is articulated with lower magnetic core array, institute State and offer what is passed through for closing piece on the closing piece that magnetic core array is rotatably connected to strip away from the one end being hinged, the lower magnetic core array Bar groove.

By the way that in this way, on turning down during magnetic core array, closing piece can enter bar groove and through bar groove, and due to closing piece and Bar groove is strip, so as to rotate the i.e. achievable effect pinned in position that closing piece to itself and bar groove is not at coordinating, and is being needed When overturning the upper magnetic core array of opening, as long as when rotating closing piece to the position coordinated with bar groove, operating more convenient, have Effect improves efficiency.

The utility model is further set：The closing piece is fixed with rubber layer close to a side surface of upper magnetic core array.

Stiction when closing piece is in locking-in state further can be improved by the setting of rubber layer, so that closing piece is not Easily there is the situation of unintentional rotation so that what closing piece can more be stablized is in locking-in state.

The utility model is further set：It is fixed with fixed cover, the closing piece and is fixed with and solid on the upper magnetic core array The elastic component that driving projection is moved toward fixed cover bottom wall direction is provided with the projection of the fixed flexible connection of set, the fixed cover.

The telescopic moving for realizing closing piece is so set, so as to can cause rubber by being drawn outside closing piece when needing to rotate closing piece Layer is not contacted with lower magnetic core array surface, and reduction frictional resistance more rotates closing piece, and it can make in elastic component after closing piece is unclamped Restored to the original state with lower, so also cause closing piece that there is certain regulating power in addition, the lower magnetic core of different-thickness can be applied to Body.

The utility model is further set：The elastic component includes spring, is provided with the opening of the fixed cover removable The perforation passed through for projection is offered on the lid unloaded, the lid, the end of the projection is provided with bulge loop, the spring one End is connected to bulge loop, and the other end is connected to lid inwall.

Cause the good installation of spring by the setting of bulge loop and lid first, so that can be fine by the elastic force of spring The reset response for realizing projection, in addition lid be detachably easy to the installation or replacing of spring.

The utility model is further set：The lid is threadedly coupled with fixed cover.

The regulation to spring force can be realized during by being so arranged on rotating cover, therefore can be according to reality Border needs to carry out rotating cover to cause spring to keep suitable elastic force, more applicability.

The utility model is further set：The projection is abutted with the inner ring of spring.

Because projection is abutted with the inner ring of spring, so that by projection support can be played a part of to spring so that bullet What spring can be stablized is stretched vertically.

The utility model is further set：The both sides of the closing piece offer hand-held groove.

So people are when needing to rotate closing piece, and the setting of hand-held groove easily facilitates the hand-held of people, rotates the behaviour of closing piece Make more easily laborsaving.

The utility model is further set：Convex portion is provided with the upper magnetic core array and lower magnetic core body sidewall, it is described convex Portion, which is combined on projection, the projection, is socketed with the framework coordinated with it.

The fixation of upper magnetic core array and lower magnetic core array can further be realized by the setting of convex portion and framework, realized dual solid Fixed effect, even if so that upper magnetic core array and lower magnetic core array are still firm when closing piece is opened accidentally is fixed together, and needing Framework need to be only removed when dismantling, it is convenient and swift.
