Description
Technical field
The utility model relates to electric energy meter technical field, is specifically a kind of electric energy meter cover opening alarm structure.
Background technology
The electric energy meter cover opening alarm structure of prior art comprises upper cover, wiring board and lower cover, and described upper cover is fixedly connected with lower cover, and described wiring board is fixed on down and covers and described wiring board is located between upper cover and lower cover.Described wiring board is provided with a pushbutton switch, covers the push rod being provided with for the pushbutton switch of conflicting on described.There is following defect in the electric energy meter switch alarm structure of said structure: electric energy meter is in the transportation of long distance, and push rod is easy to fracture or push rod deflects away from button in actual use procedure, thereby trigger the warning circuit of uncapping of electric energy meter.Therefore, the electric energy meter cover opening alarm structure functional reliability of prior art is poor.
Utility model content
The technical problems to be solved in the utility model is that the electric energy meter cover opening alarm structure that a kind of functional reliability is high is provided.
The technical solution of the utility model is, a kind of electric energy meter cover opening alarm structure is provided, and comprises upper cover, wiring board and lower cover, and described upper cover is fixedly connected with lower cover, and described wiring board is fixed on down and covers and described wiring board is located between upper cover and lower cover; On described, be covered with a telescopic metal conducting bar, described wiring board is provided with a through hole inserting for metal conducting bar, and described through-hole wall is provided with two electrodes, between described two electrodes, is provided with insulating part.
Described telescopic metal conducting bar comprises that one is provided with an opening and is fixed on the housing that covers, a portable plate, a spring, a guide pole and by the Metallic rod of opening, described Metallic rod and guide pole are separately fixed at two surfaces of portable plate, and described portable plate is slidably fitted in housing; One end of described spring is fixed on housing bottom, and the other end and the portable plate of described spring offset.
Two described electrodes are also provided with two for being close to the metal clips of metal conducting bar.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
The structure of the utility model electric energy meter cover opening alarm structure metal conducting bar and the through hole object of reporting to the police of uncapping, due to metal conducting bar not frangibility and metal conducting bar in through hole, be difficult for deviating from, therefore can not trigger the warning circuit of uncapping of electric energy meter.Therefore, the functional reliability of the utility model electric energy meter cover opening alarm structure is higher.
As improvement, two described electrodes are also provided with two for being close to the metal clips of metal conducting bar, this metal clips add the functional reliability that can effectively increase the utility model electric energy meter cover opening alarm structure.
