A Hall sensor skeleton

Abstract

The invention discloses a novel Hall sensor skeleton, which includes a primary skeleton and a secondary skeleton. The primary skeleton includes a box body, a cover plate, a frame body, and a primary adapter plate; the design of a sealed box is adopted to completely install the primary coil in the In the box, the primary high-voltage side coil is completely isolated physically, which greatly increases the insulation reliability; the primary skeleton soldering pin is removed, and the design of the adapter board is added so that the high-voltage side coil does not pass through the secondary printed board to further improve Insulation reliability is improved; the size of the primary skeleton is reduced so that the total volume will not increase greatly after it is installed in the sealed box; through the design of the corresponding bayonet and slot, the frame body, box body, cover plate and printed board Fixed together, easy and reliable installation.

Description

technical field [0001] The invention relates to the technical field of Hall current sensors, in particular to a novel Hall sensor framework with a primary and secondary framework completely isolated, which can meet the use requirements in a high-voltage working environment. Background technique [0002] As shown in Figure 1, it is an existing Hall current sensor, including a magnetic core and two skeletons. The secondary frame includes a straight square frame, and three parallel annular flanges are uniformly arranged on the outer periphery of the direction frame, and the direction frame between two adjacent flanges is used for winding compensation coils. The square frame of the primary skeleton is only provided with flanges at both ends. The bottoms of the two skeletons are provided with supporting legs for supporting the skeletons; there is also a soldering pin on both sides of the bottom, the upper ends of the soldering pins are respectively welded to one end of the two h...

Problems solved by technology

However, the insulation between the primary and secondary skeletons is generally realized only by the insulation of the enameled wire itself and the potting glue, and the insulation capacity of the enameled wire itself is limited, and the insulation effect of the potting glue is greatly affected by the structural spacing and the effect of potting bubbles; at the same time, the primary high-voltage coil Passing through the secondary printed board will cause insulation hazards. These factors make the existing Hall sensor skeleton unable to meet the requirements of high-reliability insulation in high-voltage environments
