Background technology
Existing open-loop current sensor, comprise shell, iron core, screen layer, printed board assembly, magnetic induction part, magnetic induction part is arranged in the opening of iron core, and is electrically connected with printed board assembly, also needs to arrange power interface and signaling interface, connect looser between all parts, in order to increase physical strength, usually adopt overall encapsulating, but because the factor effect such as being heated, the air gap of iron core may be caused to change, make it measure and depart from setting value.And when needing mass production, each open-loop current sensor all needs independent installation, produce complicated, precision is difficult to unified, and consistance is poor, and therefore product percent of pass is lower.Need to test each open-loop current sensor, debugging work load is large simultaneously.
Utility model content
Technical problem to be solved in the utility model is the modular open-loop current sensor providing a kind of convenient production, good product consistency for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above adopted technical scheme:
Modular open-loop current sensor, comprise shell, iron core, screen layer, printed board assembly, cap, shell is arranged the cylinder of several arrangement in step, correspondingly screen layer is by the several annulus equal with cylinder number that can be enclosed within cylinder, the iron core of corresponding number is pressed on annulus, and iron core is connected on shell by stator again, and on shell, also relative set holds the groove of printed board assembly, printed board assembly is fixed on groove, and the magnetic induction part on printed board assembly enters in the opening of iron core.
Above-mentioned cap arranges the flange identical with cylinder quantity, and cap is fastened on shell, and the flange of cap is buckled on cylinder, and such cap and shell are fixed better.
Above-mentioned screen layer several annulus composition one, once can put into several annulus, convenient installation.
Compared with prior art, the utility model has the advantage of: by the electromagnetic component modularization of each open-loop current sensor, by the modularization assembling of iron core, screen layer, make structure compacter, production and assembly facilitate and do not need encapsulating, save material and cost of labor, reduce operation and maintenance cost; As required, the quantity of current sensor can also be selected.Can debug multiple current sensor is unified, save debug time, and ensure that the consistance of product.

Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is further described.
With reference to figure 1,2,3,4, modular open-loop current sensor, comprises shell 1, iron core 3, screen layer 2, printed board assembly 5, cap 13.
Shell 1 is the matrix of whole product, and the height that this shell 1 arranges accommodation four iron cores is the cylinder 14 of stepped profile and the groove 21 of accommodation one piece of printed board assembly.
Bottom shell 1 groove 21, convex tendon 23 is set, correspondingly bottom printed board 5, breach 22 is set, inserts convex tendon 23 by breach 22 and locate printed board 5.
Shell 1 each stepped cylindrical 14 side all arranges the fixed leg for fixing stator 12, to be pressed on iron core 3 by stator 12 iron core 3 is fixed on shell 1 by self-tapping screw 11.
Groove 21 limit of shell 1 arranges fixed leg 25, correspondingly printed board 5 arranges fixed pin 10, and printed board 5 is fixed on the fixed leg 25 of shell 1 by the through hole 24 of screw 11 by fixed pin 10.
Cap 13 also arranges buckle 27, correspondingly shell 1 arranges the draw-in groove matched, by buckle 27 and draw-in groove, shell 1 and cap 13 are fixed together.
Cap 13 is provided with four flanges 28, and each flange 28 is mutually nested with the edge circular hole 29 of each cylinder of shell 1 14.
The boss 15 that shell 1 arranged outside can combine mutually and hole 16, be convenient to multiple shell 1 and linked together by boss 15 and hole 16.
