Abstract
The utility model relates to a vehicle speed sensor with simple structure, convenient connection and difficulty to be damaged, comprising the vehicle speed sensor; the outer wall of a plastic outer shell of the vehicle speed sensor is provided with a secondary boss in the circumferential direction; a metal protection ring is internally embedded in the inner wall of the plastic shell; a plug is connected with inner wall of the metal protection ring in the plastic shell; and the metal protection ring is internally provided with magnetic steel and a coil. The vehicle speed sensor has the advantages that: firstly, the outer wall of the plastic outer shell is provided with the secondary boss in the circumferential direction, thus being capable of being convenient to fixedly connect the sensor; and secondly, the metal protection ring is internally embedded in the inner wall of the plastic shell, thus strengthening the structure strength of the sensor and playing a role in protecting the magnetic steel and the coil.
Description
Technical field
The utility model relates to a kind of simple in structure, easy to connect and non-damageable vehicle speed sensor, belongs to vehicle speed sensor and makes the field.
Background technology
CN2459222, title " car speed sensor ", transmission shaft one end of this vehicle speed sensor is a gear, be connected with the automobile gearbox output terminal, the other end is equipped with magnet steel, at the magnet steel end face one inductive coil is housed, the iron core of coil has one or more pairs of utmost point pawls to be arranged in around the magnet steel, when the gear driven magnet steel rotates, form the magnetic field of a rotation, in inductive coil, produce induced potential, the variation of induced potential has reflected the variation of the polarity of rotary pole, has also just reflected the variation of automobile speed.Its weak point: the one, there is not the direct and processor connection structure connecting of energy, install inconvenient; The 2nd, easy damage, serviceable life is short.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of simple in structure, easy to connect and non-damageable vehicle speed sensor.
Design proposal: in order to realize above-mentioned purpose of design.1, the plastic casing outer wall hoop in the vehicle speed sensor is provided with the design of secondary boss, is one of technical characterictic of the present utility model.The purpose of doing like this is: when vehicle speed sensor was connected with measured piece, measured piece can be by fastening the secondary boss, thereby guarantee that measured piece is connected with the tight of sensor.2, the metal coating ring is embedded in the design of plastic casing inwall, is two of technical characterictic of the present utility model.The purpose of doing like this is: the metal coating ring can strengthen the structural strength of sensor; owing to be provided with magnet steel and coil in the metal coating ring; the metal coating ring can play the effect of protection magnet steel and coil again, avoids the damage of magnet steel and coil, guarantees that vehicle speed sensor normally moves.3, the design that is connected of the metal coating ring inwall in plug and the plastic casing is three of a technical characterictic of the present utility model.The purpose of doing like this is: plug can connect vehicle speed sensor and processor, and is provided with two contact pins in the plug, and the signal that vehicle speed sensor records can be transferred to processor by contact pin, changes into numerical value and demonstration.
Technical scheme: vehicle speed sensor; it comprises vehicle speed sensor, and the plastic casing outer wall hoop in the described vehicle speed sensor is provided with the secondary boss, and the metal coating ring is embedded in the plastic casing inwall; metal coating ring inwall in plug and the plastic casing is connected, and is provided with magnet steel and coil in the metal coating ring.
The utility model is compared with background technology, and the one, plastic casing outer wall hoop is provided with the secondary boss, can make things convenient for the fixedly connected of sensor; The 2nd, the metal coating ring is embedded in the plastic casing inwall, has strengthened the structural strength of sensor, and magnet steel and coil are played a protective role.
Description of drawings
Fig. 1 is the structural representation of vehicle speed sensor.
Fig. 2 be among Fig. 1 A to structural representation.
Fig. 3 be among Fig. 1 B to structural representation.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of vehicle speed sensor; it comprises vehicle speed sensor; plastic casing 1 outer wall hoop in the described vehicle speed sensor is provided with secondary boss 7; metal coating ring 2 is embedded in plastic casing 1 inwall; metal coating ring 2 inwalls in plug 3 and the plastic casing 1 are connected, and are provided with magnet steel 5 and coil 6 in the metal coating ring 2.
Be provided with two contact pins 4 in the described plug 3.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
