Accompanying drawing explanation
Fig. 1 is the structural representation of the signal output apparatus for oil fuse of the present invention;
Fig. 2 is the A direction view in Fig. 1;
Fig. 3 is the scheme of installation of the signal output apparatus for oil fuse of the present invention.
Embodiment
In order to understand technical scheme of the present invention better, be also described in detail by reference to the accompanying drawings below by specific embodiment.
Refer to Fig. 1 and Fig. 2, the signal output apparatus for oil fuse of the present invention, is arranged on the fusing carrier of fuse, and this signal output apparatus comprises switch cover 41, sensitive switch 42 and binding post 43; Wherein:
The front end face that switch cover 41 comprises cover plate 411, be connected to the outer ring 412 on the front end face of cover plate 411 and be connected to cover plate 411 is positioned at the switch groove 413 of outer ring 412, the cover plate 411 of this switch cover 41 is offered a cable punching hole be communicated with switch groove 413; The material of switch cover 41 is unsaturated-resin polyester;
Sensitive switch 42 to be arranged in the switch groove 413 of switch cover 41 in its contact lever mode forward and to be fixed by epoxy glue and seal;
Binding post 43 is located at the outside of switch cover 41 and is connected with three contacts of sensitive switch 42 through the three core RVV 44 of cable punching hole on switch cover 41 by one.
Refer to Fig. 3 again, oil fuse comprises the cylinder base 1 of unidirectional opening and is successively set on fusing carrier in base 1 and fuse member from base 1 opening direction; Fusing carrier comprises handle 2, and is connected with the leading section of handle 2 and the rear hookup, being packed in the rear end of the fuse member front hookup that is packed in the front end of fuse member and the linkage 3 that is movably connected on handle 2.Handle 2 comprises handle 21 and connecting rod 22, and the central authorities of handle 21 are provided with an axially extending bore, and the rear port of this axially extending bore is provided with internal thread.
The outer ring 412 of the switch cover 41 of signal output apparatus of the present invention is provided with external screw thread, makes switch cover 41 can be threaded connection with rear port at handle 21.
Signal output apparatus of the present invention, in order to be applicable to being arranged in oil fuse, the outer ring 412 of switch cover 41 is set with a sealing ring 45 again, makes switch cover 41 be encapsulated in the rear port of handle 21.Sealing ring 45 is O RunddichtringO and is made up of high temperature resistant, ageing-resistant elastomeric material.
