Abstract
A kind of magnetic tunnel junction sensor, T-shaped structure, comprise superposed transverse magnetic conductor and the dish type connector being positioned at bottom, narrow portion is provided with in the centre of described transverse magnetic conductor, the region of dish type connector described in the region overlay in described narrow portion, is connected with upright tunnel magnet on the top of described dish type connector, and described tunnel magnet is vertical with described transverse magnetic conductor, and be provided with an iron core extended out at the center of described tunnel magnet, described iron core is through described dish type connector.The magnetic tunnel junction sensor that the utility model provides, does not need the problem considering more numerous and diverse tunnel cross in the process manufactured, and directly adopts the shaping structures namely inserted, so technique is comparatively simple in the process manufactured, waste of material reduces.
Description
Technical field
The utility model relates to a kind of magnetic tunnel junction sensor, belongs to permanent magnetic sensor technical field.
Background technology
The tunnel junction sensor of prior art, a kind of tunnel junction structure that such as ZL98108447 announces, its structure is comparatively complicated, and in the process manufactured, cost is very high, so often adopt substitute in the process of marketing.But due to the advantage of tunnel junction structure itself, so be difficult to give up completely and need not.
Utility model content
The purpose of this utility model is to provide a kind of magnetic tunnel junction sensor, solves the problem that its manufacturing cost is high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of magnetic tunnel junction sensor, T-shaped structure, comprise superposed transverse magnetic conductor and the dish type connector being positioned at bottom, narrow portion is provided with in the centre of described transverse magnetic conductor, the region of dish type connector described in the region overlay in described narrow portion, is connected with upright tunnel magnet on the top of described dish type connector, and described tunnel magnet is vertical with described transverse magnetic conductor, and be provided with an iron core extended out at the center of described tunnel magnet, described iron core is through described dish type connector.
The both sides in described narrow portion are connected with the two ends transition of transverse magnetic conductor respectively by a covering of the fan.
Described iron core is cylindrical, and permanent magnetic material is contained on the surface of iron core.
The magnetic tunnel junction sensor that the utility model provides, does not need the problem considering more numerous and diverse tunnel cross in the process manufactured, and directly adopts the shaping structures namely inserted, so technique is comparatively simple in the process manufactured, waste of material reduces.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural drawing of the magnetic tunnel junction sensor described in the utility model embodiment.
