Abstract
The invention relates to an isolating switch which comprises a cover, a base seat, a connecting/disconnecting plate, an arc extinguishing plate, a handle, moving contacts, static contacts, and a spring; four groups of moving contacts, total 8 moving contacts, are installed on the connecting/disconnecting plate and connected and disconnected with the static contacts on the base seat; and the switch is a novel isolating switch which has low contact resistance, high arc extinguishing capability and small operating force.
Description
Technical field
The present invention relates to a kind of novel isolating switch, is a kind of isolating switch in the electric equipment products field.
Background technology
Isolating switch mainly is used among the electric wiring, and the usefulness of play connection, cutting off the electricity supply all is to be contained in the switch cubicle basically; The present isolating switch that uses, the operating mechanism complexity, operating physical force is big, and also inconvenient, arc-control device is simple, and the arc extinguishing ability does not reach arc quenching effect fast and effectively, and contact mechanism is also complicated, and the cost height especially can not adopt best single line contact method.Therefore produce bigger contact resistance.
Summary of the invention
The purpose of this invention is to provide a kind of novel isolating switch, its operating mechanism is simple, and operating physical force is little, convenient; The arc extinguishing ability is strong, reaches arc quenching effect fast and effectively, and contact mechanism is simple, can adopt the single line line to connect, and resistance is little when separately contacting, and can not produce big pick-up current, can not damage contact-making surface, and cost is low.
For achieving the above object, the solution that the present invention adopts is: novel isolating switch, it comprises lid, base, close branch plate, fixed contact, handle, first spring, second spring, arc quenching plate, moving contact, on base, establish a groove, after closing branch plate and lid and installing, a combination slot is arranged, close the branch plate and respectively do four U type grooves up and down;
The handle of this switch is contained in and covers, and first spring is contained on the handle, and is in the groove, makes switch close the branch function; Moving contact separates this with the fixed contact connection and partly installs arc quenching plate up and down, is in fully in the middle of the arc quenching plate, reaches arc extinguishing effect fast and effectively; Close on the branch plate and load onto a moving contact in every U type groove, load onto one second spring on the every moving contact after, install in the groove on the base, by handle, the effect of first spring makes fixed contact corresponding on moving contact and the base carry out the single line line and connects, separates.
Description of drawings
Fig. 1 is the front view of the embodiment of a kind of isolating switch of the present invention.
Fig. 2 is the cutaway view of Fig. 1;
Among the figure: 1-lid, 2-base, 3-close branch plate, 4-U type groove, 5-fixed contact, 6-handle, 7-first spring, 8-combination slot, 9-second spring, 10-bottom tub, 11-arc quenching plate, 12-moving contact.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description.
Referring to a kind of isolating switch of Fig. 1, Fig. 2, handle 6 is contained in and covers on 1, and first spring 7 is contained on the handle 6, and is in the groove 8.
As Fig. 1, Fig. 2, close in eight U type grooves 4 on the branch plate 3, respectively adorn a moving contact 12, after moving contact 12 installs, on moving contact 12, adorn one second spring 9.The branch plate 3 that closes that installs moving contact 12, second spring 9 is installed in the groove on the base 2, effect by handle 6, first spring 7, make to install closing in the bottom tub 10 of branch plate 3 on base 2 of moving contact 12, second spring and move, reach the function that fixed contact 5 corresponding on moving contact 12 and the base 2 carries out the connection of single line line, separates.
As Fig. 1, Fig. 2, moving contact 12 and fixed contact 5 are connected, separately arc quenching plate 11 all is equipped with in this part top, bottom, and dynamic and static contact is in the middle of the arc quenching plate 11 fully, reaches the effect of arc extinguishing effectively fast.
As Fig. 1, Fig. 2, four fixed contacts 5 are respectively adorned on base 2 enterprising outlet limits; Totally eight, the end that fixed contact 5 contacts with moving contact 12 is made as wedge shape.
