[technical field]
The utility model relates to ground connection and the fixed sturcture of sensor, and in particular, the utility model relates to a kind of ground connection and fixed sturcture of sensor.
[background technology]
Three kinds of modes of the general employing of currently used sensor ground connection and fixed form: the one, adopt directly to stamp out ground connection/stator (be that betal can and ground connection/stator are an integral body, ground connection/stator is the part of betal can); The 2nd, adopt butt-joint that ground connection/stator and betal can are linked together; The 3rd, with techniques such as butt-joints with sensor metal shell and complete machine altogether.With the upper type complex process, operation easier is large, efficient is low, come off easily, reliability is low.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, provides that a kind of operating procedure is simple, operation easier is low, efficient is high, and ground connection and the fixed sturcture of the high sensor of reliability.
The technical solution of the utility model is achieved in that it comprises the betal can of sensor, its improvements are: described betal can is the pole body of a hollow, be fixed with a spacing catch on the betal can, go back fixed card on the described betal can and be provided with a copper ring, be equipped with a ground connection stator between described spacing catch and copper ring, this ground connection stator comprises an annular button and ground connection and the stiff end of the sheet that is fixedly connected with annular button;
In the said structure, described betal can is provided with a step, and this step is divided into first end betal can and the second end betal can with betal can, and above-mentioned spacing catch, copper ring and ground connection stator all are arranged on the second end betal can;
In the said structure, the diameter of the first end betal can of described betal can is 2.5mm, and the diameter of the second end betal can is 4.0mm;
In the said structure, the external diameter of described annular button is 6.9mm, and internal diameter is 3.9mm;
In the said structure, the external diameter of described copper ring is 6.9mm, and internal diameter is 3.9mm, and thickness is 3.4mm;
In the said structure, be provided with thermistor in the hollow part of described betal can;
In the said structure, described ground connection stator and copper ring are fixed on the betal can by the mode of punching press.
The beneficial effects of the utility model are: the utility model is fixed with a spacing catch and a copper ring at betal can, between described spacing catch and copper ring, be equipped with a ground connection stator, the processing mode of this structure is simple, operation easier is low, substituted the mode of original direct punching press or butt-joint, and its punching structure is reliable and stable, be not easy to come off, solved the original problem of client, market is comparatively wide; In addition, the ground connection stator comprises an annular button and ground connection and the stiff end of the sheet that is fixedly connected with annular button, and annular button is buckled on the betal can by impact style, and ground connection and stiff end may be stuck on the electrical equipment, and fixed form is convenient, and it is also very convenient to use.
