Abstract
A coil-type relay comprises a shell, a coil, static polar plates, and movable polar plates, and characterized in that the positioned and movable polar plates provide screw holes, and include bolts and washers matched with the screw hole. Due to the structure, the positioned and movable pole-plates are connected with leads or electric elements and positioned with bolts tightly, so that oxidation to the positioned and movable polar plates, which is caused by high current during switch process, can be prevented. Compared with existing technologies, the device can accordingly prolong service life because it can avoid the oxidation to the positioned and movable polar plate. Therefore, the installation is convenient and circuit breaking can be prevented in order to longer service life.
Description
Technical field
The utility model relates to a kind of coil type relay.
Background technology
Present prior art, as shown in Figure 1, a kind of coil type relay comprises shell 1, coil, static plate electrode 2, movable plate electrode 3.When being applied to instant electric water heater's when other powerful household electrical appliances (or), quiet, movable plate electrode 2,3 and connection electric component grafting, because contact is not the tight of ten minutes, power is bigger in addition, long-term work, can cause the sparking of quiet, moving electrode plate, oxidation, the one, cause open circuit, the 2nd, shortened useful life.
Summary of the invention
The purpose of this utility model is: a kind of coil type relay is provided, and not only easy for installation, and can prevent to open circuit long service life.
The utility model is achieved in that a kind of coil type relay comprises shell, coil, static plate electrode, movable plate electrode, and its special character is: on described quiet, the movable plate electrode screw is arranged, also comprise cooperating screw rod, packing ring with screw.
Described coil type relay, its special character is: described quiet, movable plate electrode is plate always.
Described coil type relay, its special character is: described quiet, movable plate electrode is quiet in addition respectively, moving folding is along plate, quiet, moving folding is along screw is arranged on the plate.
A kind of coil type relay of the utility model has a screw on described quiet, the movable plate electrode, also comprises cooperating screw rod, packing ring with screw.Because adopt such structure, quiet, movable plate electrode is connected with lead or electric component, fixes with screw rod, combine closely, big caused quiet, the movable plate electrode oxidation of electric current in the time of preventing switch, compared with prior art, owing to can prevent oxidation quiet, movable plate electrode, correspondingly prolonged useful life.So not only easy for installation, and can prevent to open circuit long service life.
