Three sides are equipped with the snap seats matched with the snap collar, and the 4th side of the lower case is equipped with buckle boss, institute
The 4th side for stating upper cover is equipped with the second snap collar matched with the buckle boss, and the upper lid is equipped with and its one
Change the control panel of preparation, the inside of the control panel is equipped with to the contact chip for buckling and extending outside boss, described
The inside of lower case is additionally provided with the hall sensing chip being welded on the control panel.
Further, galvanic contact head there are four being set on the contact chip.
Further, the bottom of the lower case is annulus shape, and first through hole is equipped in the lower case.
Further, the upper cover is equipped with and the first through hole internal diameter the second through-hole of a size.
(2) beneficial effect
The utility model has the beneficial effects that compared with the prior art, the utility model is equipped with control panel, control in upper cover
The inside of plate is equipped with to the contact chip that extends outside buckle boss, and the inside of lower case is additionally provided with and is welded in control
Hall sensing chip on plate, has good impact resistance and high-intensity performance, and Environmental Safety is more convenient to install and make
With the current sensor for solving the prior art has certain limitation requirement to installation environment and system power supply, checks precision
Bigger, the bad technical problem of stability is influenced by disturbing factors such as ambient temperatures.
Detailed description of the invention
