The utility model content
To this, technical problem to be solved in the utility model is the wiring complex operation of traditional isolating switch existence and the problem of easy loose contact.
The technical scheme that realizes the utility model purpose is:
A kind of isolating switch, comprise terminal block, quiet contact and moving contact; Described quiet contact is fixed on the end of described terminal block near described moving contact, and described terminal block connects gland away from an end of moving contact by the first bolt fastening component, is provided with wiring hole between described gland and described terminal block.
In technique scheme, described moving contact comprises two contact chips that be arranged in parallel;
Described quiet contact comprises the U-shaped Connection Block consisted of two connecting plates and the base plate that is connected two connecting plates, described base plate is fixedly connected with described terminal block, the top bilateral symmetry of each connecting plate is fixed with fingertip and shell fragment, two fingertips are between two shell fragments, the top of the bottom of described fingertip, the bottom of described shell fragment and described connecting plate is fixedly connected with by rivet, and the top of described shell fragment is against on the top lateral wall of described fingertip;
When dynamic and static contact was connected, two fingertips that are arranged on same connecting plate clamped corresponding a slice contact chip.
In technique scheme, described base plate is fixedly connected with described terminal block by the second bolt fastening component.
In technique scheme, described quiet contact is provided with quiet muffler, and described moving contact is provided with moving muffler.
The utlity model has positive effect:
(1) in isolating switch of the present utility model, owing at terminal block, being provided with gland away from moving contact one end, and be provided with wiring hole between gland and terminal block, when wiring operates, only the end of wire need be inserted in wiring hole, and make terminal block and gland that wire is compressed and can realize being electrically connected to of wire and terminal block by fastening the first bolt fastening component, it is very convenient that whole wiring operates, and being connected between wire and terminal block is very reliable, can not come in contact bad.
(2) in isolating switch of the present utility model, the top that shell fragment is set is against on the lateral wall of described fingertip, so, can make two fingertips that are arranged on same connecting plate have larger chucking power by corresponding a slice contact chip clamping, thereby guarantee the reliability be electrically connected between dynamic and static contact, have good result of use.Has good result of use.
