Abstract
The utility model discloses a Hall element support, comprising a body, wherein middle of the body is magnetic steel, lower end of the body is provided with a Hall element, at least two base pins are arranged on the Hall element, at least two enclosed grooves are arranged at the side surface of the body, distance between a groove bottom of the enclosed groove and the magnetic steel is no greater than 0.45 mm, the based pins are disposed in the enclosed grooves, and the magnetic steel is prepared by neodymium iron boron strong magnetic material. Three originally open grooves equipped with the Hall element base pins are enclosed to form three hole-shaped chambers, the Hall elements are inserted into the holes and disposed in the grooves, thus the Hall element base pins can no longer form a short circuit with a shell, product quality is more reliable, and yield is substantially increased. The magnetic steel is prepared by neodymium iron boron strong magnetic material instead of weak magnetic ferrite magnet, so magnetizing amount is increased.
Description
Technical field
The utility model relates to a kind of Hall element support.
Background technology
The utility model is the part in the speed probe produced of my company, speed probe is contained in the engine gear top, magnetic field when gear rotates a tooth around the Hall element changes, the characteristic of Hall element is by changing the magnetic flux around it and then producing a pulse signal, pulse signal is transferred to car running computer, the speed when demonstrating running car then through circuit amplification, shaping after handling.The Hall element support is that to add glass fibre GF35 by nylon PA66 injection molded, and it mainly acts on is fixedly Hall element and magnet steel, joins with printed board again.
As shown in Figure 1, body 1 structure of Hall element support is subjected to the restriction of size at present, the centre of body 1 is a magnet steel 2, the groove of placing the pin 4 of Hall element 3 is an open slot 5, during design the logical of row, allow Hall element 3 when bending, keep an angle of 90 degrees, but in the production of reality, can not reach an angle of 90 degrees in the perfect condition after pin 4 bendings of Hall element 3 and be close to bottom land, cause the pin 4 of Hall element 3 can exceed the Outside Dimensions of Hall element rack body 1, bring very big trouble for the assembling of back, and can make Hall element 3 and shell short circuit, no signal occurs and export or burn out the serious consequence of Hall element circuit, can only seal with insulating tape temporarily, increase cost in order to remedy this defective, reduce production efficiency and make product quality unreliable.
Summary of the invention
Technical problem to be solved in the utility model provides the Hall element support of a kind of good insulation preformance, reliable product quality.
The technical solution of the utility model is:
A kind of Hall element support, comprise body, the centre of body is a magnet steel, the lower end of body is provided with Hall element, Hall element is provided with at least two pins, the side of body is provided with at least two enclosed slots, and the bottom land of enclosed slot and the distance of magnet steel are not more than 0.45 millimeter, and pin is placed in the enclosed slot.
The material of described magnet steel is a ndfeb magnetic material.
Beneficial effect: the utility model changes size little when satisfying required magnetic flux, then the space that remains out is used for improving the structure of Hall element support, originally three grooves that the Hall element pin is housed that open wide are closed, form three similar poroid chambeies, Hall element inserts in the hole and is placed in the groove, the Hall element pin can be not again and the shell short circuit, product quality is more reliable, yield rate increases greatly, make original magnetic steel material into ndfeb magnetic material by weak magnet Gan oxygen magnet, the amount of magnetizing is increased, though increased the little cost of producing magnet steel, cut but greatly reduce, paste the artificial of insulating tape, the expense of adhesive tape, the Hall element that burns out, many big costs such as the finished product of scrapping have improved production efficiency and yield rate widely.

Fig. 1 is a Hall element support synoptic diagram of the prior art;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the vertical view of Fig. 3.
Among the figure: 1-Hall element support, 2-magnet steel, 3-Hall element, 4-pin, 5-open slot, 6-enclosed slot.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of Hall element support, comprise body 1, the centre of body 1 is a magnet steel 2, the lower end of body 1 is provided with Hall element 3, Hall element 3 is provided with at least two pins 4, the side of body 6 is provided with at least two enclosed slots 6, and the distance of the bottom land of enclosed slot 6 and magnet steel 2 is not more than 0.45 millimeter, and pin 4 is placed in the enclosed slot 6.
The material of described magnet steel 2 is a ndfeb magnetic material.
Earlier change magnet steel 2 sizes into 5.1 * 4.8X5mm by 5.1 * 5.1 * 5mm, again the material of magnet steel 2 changed into ndfeb magnetic material by weak magnet Gan oxygen magnet, charge into identical magnetic flux, with body 1 size by
*
Mm changes into
*
Mm, change open slot and magnet steel 2 close wall thickness into 0.45mm by 0.65mm again, make saved space change the open slot that opens wide into enclosed slot 6, pin 4 with Hall element 3 inserts in the enclosed slots 6 so again, and three pins 4 of Hall element 3 just are placed in three enclosed slots 6 not can be again and the shell short circuit.The utility model is simple in structure, and it is convenient to implement, and can reach needs in the production and can raise the efficiency and yield rate, reduces cost.
Claims (2)
