Description
Technical field
The utility model relates to electric energy meter technical field, is specifically a kind of prepayment meter.
Background technology
At present, prepayment meter is easy to be subject to electromagnetic interference (EMI) and makes the relay of its inside cannot adhesive or disconnection.Therefore, after the expense practicality of prepayment, some users by large magnet adsorption on electric energy meter, with the normal disconnection of interference relay with normally electricity consumption, thus can bring about great losses to grid company.Therefore, for these reasons, urgently need a kind of prepayment meter, under the interference of magnet, relay still can normally adhesive or disconnection, to solve the problem for this prepayment meter.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of prepayment meter, and relay still can normally adhesive or disconnection under the interference of magnet for this prepayment meter.
The technical solution of the utility model is, provides a kind of prepayment meter, comprises electric energy meter casing, wiring board and relay, and described wiring board is arranged in electric energy meter casing; Described relay welding in the circuit board; Described relay outside surface is coated with the ferrous casings that one deck prevents magnet from disturbing, and described ferrous casings is made up of the first iron plate, the second iron plate, the 3rd iron plate; The first described iron plate and the 3rd iron plate are parallel to each other; The second described iron plate is connected with the side of the first iron plate, the side of the 3rd iron plate respectively; The first described iron plate or the 3rd iron plate are provided with the through hole stretched out for relay stitch.
The both sides of the first described iron plate or the 3rd iron plate are also provided with two limited blocks.
Described first iron plate, the second iron plate, the 3rd iron plate are all bonding with the outside surface of relay.
The thickness of described first iron plate, the second iron plate, the 3rd iron plate is 1-3mm.
After adopting above structure, the utility model compared with prior art, has the following advantages:
The relay outside surface of the utility model prepayment meter is coated with the ferrous casings that one deck prevents magnet from disturbing, and this ferrous casings effectively prevent the interference of magnet, makes relay can normally adhesive or disconnection, thus effectively prevent stealing.
As improvement, the both sides of the first described iron plate or the 3rd iron plate are also provided with two limited blocks.The setting of this limited block prevents the slip of ferrous casings effectively, thus can reliably prevent magnet from disturbing.
As improvement, described first iron plate, the second iron plate, the 3rd iron plate are all bonding with the outside surface of relay.The setting of this bonded structure prevents the slip of ferrous casings effectively, thus can reliably prevent magnet from disturbing.
As improvement, the thickness of described first iron plate, the second iron plate, the 3rd iron plate is 1-3mm.This thickness can prevent magnet from disturbing well again on the basis ensureing whole electric energy meter cost.
