Abs sensor mainly comprises linear wheel speed sensors, annular wheel speed sensors and Hall wheel speed sensor, and present existing hall sensor is mainly by the Hall pipe, shell, electrical lead, the electrical lead sheath, plug, plug body consists of, described Hall pipe is loaded in the shell, be connected by electrical lead between Hall pipe and the plug, structurally there is following defective in it: (1) is because in the existing hall sensor, on the link circuit of its Hall pipe and plug-in power pack corresponding overcurrent is not set, overvoltage, the protection such as filtering and wave shaping components and parts, therefore when the outside electric current of inputting and overtension or when unstable, not only can affect the accuracy of sensor measurement, but also can shorten the serviceable life of sensor; (2) junction of electrical lead sheath and shell and plug body is because there is the gap usually in the impact of machining precision and error, easy water leaking-in etc. in the use procedure, thus cause security incident.
Summary of the invention
For the deficiencies in the prior art, the invention provides the Hall-type abs sensor that a kind of structure is more reasonable, security performance is more reliable and stable.
For achieving the above object; the invention provides a kind of Hall-type abs sensor; comprise Hall subassembly; shell; electrical lead; the electrical lead sheath; plug; plug body; described Hall subassembly is loaded in the shell; be connected by electrical lead between Hall subassembly and the plug; described Hall subassembly comprises wiring board; the Hall pipe; described Hall pipe is loaded on the wiring board; also be provided with the overcurrent protection resistance that is electrically connected with the Hall pipe on the described wiring board; power filtering capacitor; stabilivolt; wave shaping electric capacity; wiring board is fixedly arranged in the shell by injection moulding; and be coated with dense glue-line in 704 between the resin injection molded layers of wiring board and shell; electrical lead is loaded in the electrical lead sheath; electrical lead sheath two ends are connected with shell and plug body respectively, and the junction of electrical lead sheath two ends and shell and plug body is provided with the zigzag capillary groove.
The invention has the beneficial effects as follows: adopt said structure; because the present invention has set up overcurrent protection resistance at the link circuit of Hall pipe and plug-in power pack; power filtering capacitor; stabilivolt; wave shaping electric capacity; therefore no matter how foreign current and voltage change; can both guarantee the normal measurement of sensor and the accuracy of measurement; described Hall pipe of while; overcurrent protection resistance; power filtering capacitor; stabilivolt; wave shaping electric capacity all is fixedly arranged on the wiring board; described wiring board and shell are by injection mo(u)lding; can make reliable and stable that each components and parts on wiring board and the wiring board install; also be coated with dense glue-line in 704 between the resin injection molded layers of wiring board and shell; expanding with heat and contract with cold of casting resin impacts the components and parts on wiring board and the wiring board in the time of can preventing injection moulding; the junction of electrical lead sheath two ends and shell and plug body is provided with the zigzag capillary groove in addition; can realize the effect of multilayer flashing; avoid causing sensor to seep water because of the impact of machining precision and error, can improve widely the security performance of sensor.
The present invention can further be set to be provided with in the described plug body plug and plug locating piece, described plug is made of plug contact jaw and plug handle, and the external diameter of plug handle is greater than the external diameter of plug contact jaw, described plug locating piece is fixedly arranged in the plug body, the plug locating piece is provided with lug, and described lug is provided with the through hole suitable with the plug contact jaw.
Adopt said structure, because described lug is provided with the through hole suitable with the plug contact jaw, therefore when the assembling plug, the plug contact jaw can be passed the through hole of lug, its plug handle is stayed the lug inboard, so just can avoid the workman in assembling during plug, because the length that passes of accurate polarized plug causes and assembles the different in size of rear each plug, thus the problems such as loose contact that cause.
The link that the present invention also can further be set to described Wire sheath and shell is provided with the injection moulding buckle, described shell be provided with Wire sheath on the catching groove that is interlocked of injection moulding buckle.
Adopt said structure, link at described Wire sheath and shell arranges the injection moulding buckle, the catching groove that the injection moulding buckle is interlocked on described shell setting and Wire sheath can be avoided causing the misconnection of each components and parts on wiring board and the wiring board logical because of injection moulding buckle misplug.
