Abstract
A surface acoustic wave wireless temperature sensor for measuring power switch cabinet static contact temperature is characterized in that: a sensor comprises an antenna, a surface acoustic wave temperature sensitive element, a metal fixed part, a metal casing and a spring binding ligature; the antenna and the surface acoustic wave temperature sensitive element are arranged on the metal fixed part, and screwed in the metal casing, and the metal casing by the spring binding ligature is fixed on the power switch static contact.
Description
Technical field
The utility model relates to sensor field, relates in particular to the structural design of temperature sensor.
Background technology
Surface acoustic wave wireless temperature sensor is a kind of passive wireless temperature sensor, have completely passive (not needing powered battery), temperature-measuring range wide, the advantage such as can wirelessly read, be applicable to the thermometric of power equipment, motor-car wheel shaft etc.Surface acoustic wave wireless temperature sensor is generally comprised of surface acoustic wave temperature-sensing element (device), fixed sturcture, heat transfer structure, antenna and packaging part.The like product for power switch cabinet static contact thermometric occurring in the market has following characteristics and shortcoming:
1) fixed sturcture using P.e.c. (PCB) plate as surface acoustic wave temperature-sensing element (device) and antenna.Pcb board is organic material normally, and long-time high temperature can produce the problems such as buckling deformation, carbonization be frangible.
2) sensor is fixed on columniform static contact by inelastic band.Band does not have elasticity, cannot guarantee the close contact of sensor and tested surface, or causes sensor to damage because band installs too tight.
Summary of the invention
For the problem of existing product on market, the utility model proposes a kind of surface acoustic wave wireless temperature sensor of new construction, have advantages of easy for installation, temperature tracing property is good, reliability and durability, is applicable to the thermometric of this class cylindrical object of power switch cabinet static contact.
Surface acoustic wave wireless temperature sensor of the present utility model, is characterized in that: sensor is comprised of antenna, surface acoustic wave temperature-sensing element (device), metal fixing, metal shell and spring binding strip; Antenna and surface acoustic wave temperature-sensing element (device) are arranged on metal fixing, and are screwed in metal shell, and metal shell is fixed on power switch cabinet static contact by spring binding strip.
In order to have good contacting with the cylindrical static contact of power switch cabinet, arc-shaped concave is arranged at side or the bottom of metal shell, for column type measured object close contact.
For the ease of linking springs binding strip, on metal shell, there are two Screws, for twisting, connect spring binding strip.
Surface acoustic wave wireless temperature sensor of the present utility model is not used PCB, can use by long term high temperature.By spring binding strip and static contact, fix, can select according to actual needs the elasticity of spring, guarantee reliability and the convenience of installing.
Below in connection with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the integrally-built specific embodiment of sensor..
Fig. 2 is the structural drawing after antenna, surface acoustic wave temperature-sensing element (device) and metal fixing assembling.
Embodiment
Fig. 1 is the integrally-built specific embodiment of sensor.The centre of aluminium shell is a screw, and side is an arc-shaped concave.The diameter of arc-shaped concave is determined according to the specification of static contact, and therefore typical diameter has 35mm, 49mm, 55mm, 79mm, 109mm etc.Arc-shaped concave respectively have up and down a Screw, for linking springs.Shell and spring form a lasso with retractility like this, are enclosed within on static contact.
Fig. 2 is the structural drawing after antenna, surface acoustic wave temperature-sensing element (device) and the assembling of copper fixture.Antenna is screwed in the screw of fixture, and surface acoustic wave temperature-sensing element (device) is welded on the concave station of copper fixture, and joins with antenna.The structure of Fig. 2 can be screwed in aluminium shell by the external thread on fixture.
Above example is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
