Description
Technical field
The present invention relates to closed-loop Hall current sensor.
Background technology
Closed loop or magnetic balance type Hall current sensor are the sensors utilizing Hall effect big current to be transformed to secondary small voltage signal, because of its have that measurement range is wide, electrical isolation performance is good, measuring accuracy is high, the interference performance of the factor such as good, the anti-external electromagnetic of the linearity and temperature is strong, current-rising-rate large, fast response time, overload capacity strong, install the features such as simple, convenient, is widely used in the aspects such as industrial automation technology, detection technique and information processing.But complex procedures during components and parts assembly operation in closed-loop Hall current sensor in the market, time-consuming, affect production efficiency, be therefore necessary to improve.
Summary of the invention
Technical matters to be solved by this invention be overcome prior art above-mentioned deficiency and a kind of closed-loop Hall current sensor is provided, there is the features such as structure is simple, easy to assembly.
The present invention's adopted technical scheme that solves the problem is: the heat sink that closed-loop Hall current sensor comprises triode, device has heating radiator, main circuit board assembly, connector, coil, coil fixing support, heat sink has circular hole, main circuit board Components integration is in printed board, printed board also has the circular hole concentric with the circular hole on heat sink, be provided with square hole stud above coil fixing support and coil fixing support is provided with groove.Triode and heat sink are fixed by heat-conducting double-sided adhesive tape, square hole stud on coil fixing support is fixed by screw through after printed board circular hole, heat sink circular hole successively, and between printed board and heat sink, square hole stud overcoat has spacer, coil relies on adhesive tape to be bundled in below coil fixing support, adhesive tape is wrapped in the groove of coil fixing support, connector is also socketed with every post outward, and above-mentioned components and parts, assembly load shell, and are solidified by casting glue.
Compared with prior art, the invention has the advantages that: heating radiator and triode are fixed by heat-conducting double-sided adhesive tape, both ensure that radiating effect, make again simple to operation; Coil fixing support, printed board, heat sink are fixed by square hole stud, screw, and coil is bundled on coil fixing support by blend compounds band, and operation is simple, save man-hour, and the intensity adopting square hole stud, screw fixing is high.

Embodiment
Below in conjunction with accompanying drawing, embodiment, the present invention is further described.
Embodiment, closed loop Hall current sensor as Figure 1 and Figure 4, comprise shell 1, coil 2, coil fixing support 3, printed board 4, spacer 5, triode 6, heat-conducting double-sided adhesive tape 7, heat sink 8, connector 9, every post 10, adhesive tape 11, screw 12.On heat sink 8, device has heating radiator, and edge has circular hole, comprise the main circuit board Components integration of Hall element in printed board 4, printed board 4 edge also has the concentric circle holes corresponding with heat sink 8, square hole stud 31 is provided with above coil fixing support 3, square hole stud 31 can pass circular hole, and coil fixing support is provided with groove 32.
Assembling process as shown in Figure 2 and Figure 3, first selects the heat-conducting double-sided adhesive tape 7 that viscosity is strong, thermal resistance is little, coefficient of heat conductivity is high to bond fixing by triode 6 and heat sink 8; Again the square hole stud 31 on coil fixing support 3 is passed printed board circular hole, heat sink circular hole successively, and between printed board 4 and heat sink 8, square hole stud 31 overcoat has spacer 5, the external diameter of spacer 5 is greater than the diameter of circular hole, make to leave enough spaces between printed board 4, heat sink 8, prevent components and parts short circuit or be extruded, screw 12 is screwed in stud 31, coil fixing support 3, printed board 4 and heat sink 8 are fixed together; Adopt adhesive tape 11 to be bundled in below coil fixing support 3 by coil 2 afterwards, due to coil fixing support 3 leaving groove 32, coil fixing support 3 and printed board 4 are equivalent to leave a gap after fixing between the two, and adhesive tape 11 can pass in this gap.In like manner, lost efficacy to prevent connector 9 to be extruded, the outer also cover of connector 9 has every post 10.After the components and parts assembled, assembly are put into inductor shell 1, solidified by casting glue, process flow as shown in Figure 5.Obviously, heat-conducting double-sided adhesive tape, adhesive tape, square hole stud, screw can be replaced by other equivalent unit.
