Abstract
The utility model relates to a sensor for measuring wheel speed by automotive electronics, in particular to a passive wheel speed sensor. The passive wheel speed sensor comprises a framework, a coil, magnetic steel, a sleeve, a fixing shell and a cable, wherein the coil is arranged at the outer surface of the framework; the left end of the magnetic steel is connected with the right end of the framework; the fixing shell is positioned at the right end of the magnetic steel; the right end face of the fixing shell is provided with a pin; an anode and a cathode of the coil are respectively communicated with pins after passing through a through hole on the fixing shell; the pins are communicated with the cable; the coil, the fixing shell and the magnetic are respectively sheathed with a sleeve externally; the through hole on the fixing shell is internally provided with a plastic isolation dowel; and connecting leads between the coil and the pin are respectively positioned at two sides of the plastic isolation dowel. The advantages are as follows: the sensor is simple in structure and convenient in manufacturing, increases the production efficiency by isolating left and right pins through the plastic isolation dowel and reduces the rejection rate of products.
Description
Technical field
The utility model relates to the sensor that a kind of automotive electronics is measured wheel speed, particularly a kind of passive wheel speed sensor.
Background technology
At present, at home and abroad on high-grade car and the high-grade truck employed sensor the most widely used be passsive sensor.And because the passsive sensor production run need encapsulate by injection moulding, cable is connected with the welding of left and right sides contact pin again, and the injection moulding process that adds high pressure at high temperature causes the short circuit phenomenon of left and right sides cable or stitch easily, thereby makes product rejection.
The utility model summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, and a kind of short circuit phenomenon that causes that can avoid in the sensor production process is provided, and adds the passive wheel speed sensor that spacing block is isolated in the middle of the contact pin of the left and right sides.
In order to achieve the above object, the utility model adopts following technical scheme: passive wheel speed sensor, comprise skeleton, coil, magnet steel, sleeve pipe, set casing and cable, coil is arranged on the skeleton outside surface, the magnet steel left end is connected with the skeleton right-hand member, set casing is positioned at the magnet steel right-hand member, described set casing right side is provided with contact pin, the both positive and negative polarity of coil passes on the set casing through hole respectively with contact pin be communicated with, contact pin be connected with cable, coil, set casing and magnet steel are socketed with sleeve pipe outward respectively, it is characterized in that: be provided with the plastic barrier pin on the described set casing in the through hole, be connected the both sides that lead lays respectively at the plastic barrier pin between coil and the pin.
For a kind of optimization of the present utility model, described set casing outer tube and cable front end encapsulate the formation holder by sealing filler respectively.
The utility model is compared with background technology, has simple in structurely, easily manufactured, by the plastic barrier pin left and right sides stitch is isolated, and has increased the production efficiency in producing, and has reduced the scrappage of product.
