Abstract
The utility model discloses a magneto-electric gear sensor, which comprises an outer shell, wherein a sensor component is arranged in the outer shell and comprises a fixed bracket, an electromagnetic coil, an ion core and a magnet; the fixed bracket is fixedly arranged in the outer shell; the electromagnetic coil is wound on the fixed bracket; the ion core is inserted into the fixed bracket and used for cutting the electromagnetic coil; the magnet is arranged in the fixed bracket; and one end of the magnet is attracted with the ion core, and an elastic plastic plug is arranged between the other end of the magnet and the fixed bracket. By adoption of the structure, the elastic plastic plug is arranged between the magnet and the fixed bracket, so impact force generated by attraction or non-attraction of the magnet and the ion core can be effectively reduced, damage to all parts in the sensor component caused by impact can be effectively avoided, and the overall service life of the sensor is prolonged.
Description
Technical field
The utility model relates to a kind of magneto-electric gear sensor.
Background technology
The magneto-electric gear sensor is a kind of magnetoelectric sensor that is used for prototype gear wheel speed, and its structure mainly comprises shell body, is equiped with sensor module in the described shell body; Described sensor module comprises fixed support, solenoid, iron core, magnet; Fixed support is installed in the shell body, and solenoid is set around on the fixed support, and described iron core is arranged in the fixed support; And formation is to the cutting of solenoid; Also be equiped with magnet in the described fixed support, an end of magnet is inhaled mutually with iron core and is joined, and the other end of magnet pushes up with fixed support mutually joins.Because in the working sensor process; Magnet and iron core ceaselessly adhesive or separate in the other end of magnet will constantly clash into fixed support; And be that join on rigid top between magnet and the fixed support in the prior art; Any snubber assembly is not set, and therefore each parts in the sensor module are damaged easily in rigid knockout process, and then shorten the whole service life of sensor.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of magneto-electric gear sensor that increases the service life.
For realizing above-mentioned purpose, the utility model provides a kind of magneto-electric gear sensor, comprises shell body; Be equiped with sensor module in the described shell body, described sensor module comprises fixed support, solenoid, iron core, magnet, and fixed support is installed in the shell body; Solenoid is set around on the fixed support; Described iron core is arranged in the fixed support, and constitutes the cutting to solenoid, also is equiped with magnet in the described fixed support; One end of magnet is inhaled mutually with iron core and is joined, and is equiped with the elastoplast plug between the other end of magnet and the fixed support.
The beneficial effect of the utility model is: adopt said structure; Because the utility model has been set up the elastoplast plug between magnet and fixed support; Therefore can effectively alleviate the impact that magnet is produced with the iron core adhesive or when separating; Thereby can effectively avoid each parts in the sensor module to be damaged, and then prolong the whole service life of sensor because of bump.
The utility model can further be set to described elastoplast plug and be located on the fixed support through nylon glue is sticking.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1ly provided a kind of magneto-electric gear sensor; Comprise shell body 1, be equiped with sensor module 2 in the described shell body 1, described sensor module 2 comprises fixed support 21, solenoid 22, iron core 23, magnet 24; Fixed support 21 is installed in the shell body 1; Solenoid 22 is set around on the fixed support 21, and described iron core 23 is arranged in the fixed support 21, and constitutes the cutting to solenoid 22; Also be equiped with magnet 24 in the described fixed support 21; One end of magnet 24 is inhaled mutually with iron core 23 and is joined, and is equiped with elastoplast plug 3 between the other end of magnet 24 and the fixed support 21, and described elastoplast plug 3 is through nylon glue 4 sticking being located on the fixed support 21.Adopt said structure; Because the utility model has been set up elastoplast plug 3 between magnet 24 and fixed support 21; Therefore can effectively alleviate the impact that magnet 24 is produced with iron core 23 adhesives or when separating; Thereby can effectively avoid each parts in the sensor module 2 to be damaged, and then prolong the whole service life of sensor because of bump.
