Abstract
The utility model discloses a sensing head of a vehicle sensor. The sensing head of the vehicle sensor includes a plastic shell and sensing components disposed in the plastic shell. The sensing components include a coil, a coil frame, a wiring terminal, an iron core and a steel magnet. The coil is coiled on the coil frame. The coil is connected with a lead electrically through the wiring terminal. The iron core and the steel magnet are arranged in an inner hole of the coil frame. The sensing head of the vehicle sensor is characterized in that an opening of the plastic shell for receiving the sensing components is filled with epoxy resin. The sensing head of the vehicle sensor provided by the utility model can be applied to an ABS (Anti-lock Block System) sensor, a crankshaft position sensor, a camshaft position sensor and other automobile sensors. The sensing head of the vehicle sensor has advantages of good sealing performance, good electromagnetic interference capacity, high flexibility and low cost.
Description
[technical field]
The utility model relates to a kind of sensor, is specifically related to a kind of sensing head of automobile sensor.
[background technology]
Automobile sensor comprises ABS anti-lock braking system sensor, crankshaft position sensor, CMPS Camshaft Position Sensor etc., and it has vital meaning to safe driving and the automatic control of automobile.Sensing head is the core component of sensor, and the ubiquitous deficiency of sensing head has at present: relatively poor, the anti-electromagnetic interference performance of sealing property is relatively poor, sensitivity is lower, cost is higher.
[summary of the invention]
For the deficiency that prior art exists, the purpose of this utility model aims to provide a kind of good seal performance, anti-electromagnetic interference performance is good, highly sensitive, cost is low automobile sensor sensing head.
The utility model is implemented by the following technical programs:
The sensing head of automobile sensor, comprise plastic casing and pack the interior sensing element of plastic casing into, sensing element comprises coil, coil former, connection terminal, iron core and magnet, coil is on coil former, coil is electrically connected with wire by connection terminal, iron core and magnet are located at the endoporus of coil former, it is characterized in that: pack into the opening packing ring epoxy resins of sensing element of plastic casing.Pack into a side end face of sensing element of plastic casing is provided with the stainless steel protective cover.The end face that magnet deviates from iron core arranges pure iron.
The sensing head that the utility model provides, the opening packing ring epoxy resins of sensing element because plastic casing is packed into, epoxy resin after the curing has the characteristics such as adhesion is strong, shrinkability is little, insulativity is excellent, can sensing element be played a very good protection good seal performance; The stainless steel protective cover effectively block electromagnetic undesired signal is set, guaranteed the integrality of sensing head collection signal; In addition, arranging of pure iron replaced original a part of magnet, so the thickness attenuation of magnet has not only reduced cost, and can strengthen magnetic flux, thus the sensitivity that improves sensing head.
[description of drawings]
Description of drawings:
Fig. 1 is structural representation of the present utility model.
[embodiment]
With reference to accompanying drawing 1; the sensing head of automobile sensor of the present utility model; comprise plastic casing 5; sensing element in stainless steel protective cover 1 and the plastic casing 5 of packing into; sensing element comprises coil 10; coil former 9; connection terminal 4; iron core 8; magnet 7 and pure iron 6; coil 10 is on coil former 9; coil 10 is electrically connected with wire 2 by connection terminal 4; iron core 8; magnet 7 and pure iron 6 are located at the endoporus of coil former 9; pack into the opening packing ring epoxy resins 3 of sensing element of plastic casing 5; epoxy resin 3 after the curing has improved the sealing of sensing head; sensing element is played a very good protection; stainless steel protective cover 1 is connected to pack into a side end face of sensing element of plastic casing 5; effective block electromagnetic undesired signal; guaranteed the integrality of sensing head collection signal; described pure iron 6 is located at the end face that magnet 7 deviates from iron core 6; arranging of pure iron 6 replaced original a part of magnet; so thickness attenuation of magnet; not only reduced cost; and can strengthen magnetic flux, thereby improve the sensitivity of sensing head.
