Description
Technical field
The utility model relates to a kind of relay, relates in particular to a kind of time relay.
Background technology
The time relay is a kind of use on the circuit of lower voltage or small electric stream, the electric component of the circuit that is used for switching on or off high voltage, larger electric current.Meanwhile, the time relay is also a kind of control apparatus that utilizes electromagnetic principle or theory of mechanics to realize time delay control.At present, the most time relay exists and manufactures complexity, poor reliability, failure rate is high, the life-span is short, high in cost of production shortcoming.
Utility model content
For solving existing problem in above-mentioned prior art, the utility model provides the time relay of growing a kind of failure rate is low, mechanical endurance.
The utility model adopts following technical scheme to realize: a kind of time relay, comprise base and time relay body, described time relay body comprises shell and is arranged on the circuit part of shell inner cavity, described circuit part comprises electromagnetic relay assembly, circuit board assemblies, show control assembly and Power Supply Assembly, described electromagnetic relay assembly, show control assembly, Power Supply Assembly is all electrically connected with described circuit board assemblies, described electromagnetic relay assembly is provided with 13 pins, on described base, be provided with the jack coordinating with described pin, described pin passes in the jack that described shell is plugged on described base, on the panel of described shell, be provided with opening, described demonstration control assembly passes described opening, the armature winding of described Power Supply Assembly is connected between pin (1) and pin (2), the secondary winding of described Power Supply Assembly is connected on the power input of described circuit board assemblies, pin (2) and pin (7) are by wire short circuit, between pin (7) and pin (8), be serially connected with normally closed delay switch.
Preferably, described demonstration control assembly comprises display screen and dial-up controller.
Preferably, described Power Supply Assembly is transformer.
Compared with prior art, the utlity model has following beneficial effect: the utility model circuit is simple, use simple, pin (2) and pin (7) are passed through to wire short circuit, effectively reduce failure rate, extended mechanical endurance, improved reliability.
