Transparent cover plate of the cover on each terminal screw is provided on pedestal, and corresponds on transparent cover plate and is set respectively at each terminal screw
There is wiring hole, /V raised line is provided on the lower face of the transparent cover plate, be provided on the pedestal and /V raised line
Matched limiting slot, the /V raised line is installed in limiting slot, and multiple cards are provided on the lower face of transparent cover plate
It hooks, the card slot for being both provided with and being adapted at each hook is corresponded on the pedestal, the hook is installed in card slot and forms
The clamping engagement of transparent cover plate and pedestal.
The advantageous effect of said structure is：The electromagnetic relay have it is simple in structure, performance is stable, it is safe and reliable, work
The advantages of state instruction understands by being provided with transparent cover plate of the cover on terminal screw on pedestal, can avoid operator
Member touches terminal screw, and transparent cover plate is connected with pedestal by the way of snapping connection, convenient for pedestal and transparent cover plate
Assembling, and the /V raised line of position-limiting action has been provided on transparent cover plate, it ensure that the connection of pedestal and transparent cover plate is more compact.
Particularly, the instruction device includes the wiring board being arranged on the bobbin of electromagnetic system, is arranged on circuit
LED light on plate is provided with transparent light guide column on the lower face of the transparent cover plate, and the lower end of transparent light guide column passes through
Through hole on pedestal and the surface of LED light is extended in, and optically focused groove is provided on the lower face of transparent light guide column, institute
Corresponded on the transparent cover plate stated at the surface of transparent light guide column set it is fluted, spherical transparent protective cover is provided in groove.
By being arranged above transparent light guide column in LED light, the optically focused groove on transparent light guide column can be by LED light
Light source is gathered on transparent light guide column, and the groove on transparent cover plate can avoid the light source of LED light from reflecting entire transparent
On cover board, so as to which the light source of LED light can be all incident upon on spherical transparent protective cover by transparent light guide column, consequently facilitating behaviour
Make personnel clearly, be visually observed that the working condition of the electromagnetic relay.
