Abstract
A split type large current direct-discharging Hall current sensor comprises an upper casing, a lower casing, two iron cores, a sheath, a main circuit printed board, a Hall component and a shielding line. One end of the shielding line is connected with the iron cores, the other end of the shielding line is connected with the main circuit printed board, the two iron cores are arranged in the upper casing and the lower casing respectively, the sheath is arranged between the two iron cores, a hole for placing the Hall component is arranged in the middle of the sheath, the sheath is limited through a limit rib arranged on the casings, and the main circuit printed board is fixed on a fixing column of the casings and a fixing column of the sheath. The split type large current direct-discharging Hall current sensor has the advantages that the split type large current direct-discharging Hall current sensor is not easy to deform, Hall location is accurate, the main circuit printed board is firm in fixation, and product quality is good.
Description
Technical field
This practicality relates to a kind of current sensor, the particularly split type Hall current sensor of directly putting.
Background technology
Existing split type big electric current is directly put Hall current sensor and had following shortcoming: shell length is very long up and down for (1), sensor, the phenomenon of interior compression deformation in the middle of being prone to cause.(2), manually-operated is adopted in the location of Hall air gap, the very difficult production air gap consistance that guarantees.(3), main circuit board and housing location is insufficient, is difficult to guarantee constant intensity.
Summary of the invention
This practical technical matters to be solved is to overcome the above-mentioned deficiency of prior art and provide a kind of split type big electric current directly to put Hall current sensor, makes that its shell is not yielding, Hall accurate positioning, quality be good.
This practicality solves the problems of the technologies described above the technical scheme that is adopted:
Split type big electric current is directly put Hall current sensor; Comprise up and down two shell, two iron cores, sheath, main circuit printed panel, Hall element, shielding line; Shielding line one end is connected with iron core, and the other end is connected with the main circuit printed panel, and two iron cores place lower casing respectively; Sheath is arranged between two iron cores; The hole of placing Hall element is set in the middle of the sheath, and sheath is spacing by the spacing muscle that shell is provided with, and the main circuit printed panel is fixed on the anchor post of fixed leg and sheath of shell.
By thin progressive additive, the centre also all is provided with reinforcement from both sides to the centre for above-mentioned upward shell and lower casing, to strengthen going up the intensity of lower casing.
The above-mentioned lower casing two parts of going up are realized being connected and locating through the boss and the cooperation in hole.
At the last lower casing place that matches, the binding face of the cooperation place of a shell is merely two ends screw assembling place.
Above-mentioned main circuit printed panel also can be fixed more firm by the anchor post welding of sheath like this.
Compared with prior art, this practical advantage is:
Last shell and lower casing from both sides to the centre by thin progressive additive, the centre also all is provided with reinforcement, has improved anti-deformation.
Increased the spacing muscle of sheath; Reach accurate location to sheath; Guarantee to rely on the size of gaps between the iron core of sheath location, made that to rely on the iron core of sheath location more accurate with the location of shell, passed through the main circuit printed board of the fixedly Hall element weld of sheath anchor post simultaneously; Guaranteed the accurate location of Hall element, constant intensity also is significantly improved.
Increased main circuit printed panel anchor post on the shell, the main circuit printed board is fixed with self-tapping screw and shell, convenient fixing, intensity enhancing.
Because shell two parts is up and down realized the location through boss and cooperating of hole, the impression that produces through interference fit makes product accurate positioning when repeated removal is installed, and reduces the repetition installation errors.
At the lower casing place that matches with last shell, its binding face of lower casing mating surface is merely two ends screw assembling place, thereby reduces to install the unstable problem of performance that distortion brings.

Embodiment
Embodiment further describes this practicality below in conjunction with accompanying drawing.
Like Fig. 1, shown in Figure 2; Split type big electric current is directly put Hall current sensor; Comprise shell 1, lower casing 8, upper core 2, lower core 6, sheath 5, main circuit printed panel 3, shielding line 7, two iron cores place lower casing respectively up and down, and sheath 5 is arranged between upper core 2, the lower core 6; Shielding line 7 one ends link to each other with upper core 2, and the other end is connected with main circuit printed panel 8.
Above-mentioned sheath 5 surfaces also are provided with positioning pillars 51, are used for supporting and location main circuit printed panel 8, can hot pick pillar 51 and make main circuit printed panel 8 fixing more firm.
Above-mentioned sheath 5 also is provided with hole 52, places Hall element in the hole 52, can accurately locate Hall element.
The spacing muscle 13 that above-mentioned sheath 5 also is provided with by shell 1 cooperates spacing, reaches the accurate location to sheath 5, has guaranteed to rely on the size of gaps between the iron core of sheath 7 location, sees Fig. 5.Cooperation through sheath and the spacing muscle of shell makes that to rely on the iron core of sheath location more accurate with the location of shell, passes through the fixedly main circuit printed board of Hall weld of hot pick of sheath pillar simultaneously, has guaranteed the accurate location of Hall.
Above-mentioned main circuit printed panel 8 is fixed on through screw 4 on the fixed leg 11 of shell 1 setting, and main circuit printed board 8 usefulness self-tapping screws 4 are fixed with last shell 1, see Fig. 3, Fig. 4, and easy to operate like this, intensity is big.
Above-mentioned go up shell 1 outer wall from both sides to the centre by thin progressive additive, and in the centre reinforcement 12 is set and supports shell walls, improve the problem of interior compression deformation in the middle of the lower casing.
Last shell is located with the realization that cooperates in the hole 14 of last shell through the boss 84 of lower casing with lower casing two parts, and the impression that produces through interference fit makes product accurate positioning when repeated removal is installed, and reduces the repetition installation errors.
Last lower casing up and down under the shell place of the matching shell its binding face of mating surface be merely two ends screw assembling place, and fixing with screw 9, see Fig. 6, thereby reduce to be out of shape the performance shakiness problem of bringing because of installing.
