Description
Technical field
The utility model is related to a kind of contact apparatus, more particularly, to a kind of contact apparatus of automatic transfer switching electric appliance.
Background technology
Current PC grades of automatic transfer switching electric appliance, it be greatly to be formed by two disconnecting switch overlap joints to have, that is, derive from
Type automatic transfer switching electric appliance.It is due to being two disconnecting switch overlap joints, so will respectively there is two sets to connect dynamic with disjunction
Contact and static contact.This has resulted in that small product size is big, parts are more, and high cost, interlocking mechanism are excessively cumbersome etc..Due to zero
Part is more, easily causes mechanism's clamping stagnation, and interlocking is unsuccessfully etc..Additionally, due to being two sets of independent dynamic/static contact systems, its leading-out terminal band need to
Conflux, greatly improve its cost.
Utility model content
The purpose of this utility model is exactly to provide a kind of automatic conversion for the defect for overcoming above-mentioned prior art to exist
The contact apparatus of device for switching.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of contact apparatus of automatic transfer switching electric appliance, including moving contact, static contact, and it is described dynamic and static for installing
The shell of contact, described static contact includes being arranged on shell side and in two groups of end of incoming cables static contacts being distributed up and down, and
One group of leading-out terminal static contact of the opposite side of shell is arranged on, described moving contact is arranged on by two groups of end of incoming cables static contacts and one
The centre position of the triangle that group leading-out terminal static contact is surrounded, and can be rotated around the central rotation of triangle point；
When moving contact is pressed different directions and is rotated in place around central rotation, leading-out terminal stationary contact described in the end thereof contacts of moving contact
Head, the other end contacts two groups of end of incoming cables static contacts respectively.
Preferably, described moving contact includes the contact body in yi word pattern, and around central rotation point rotation
Rotating disk, described contact body is fixed at disk edge.
It is furthermore preferred that the two ends of described contact body process oriented open-ended U-type groove respectively；
When moving contact is rotated in place, the end of the static contact is slipped into correspondence U-type groove, and is closely connect with U-type groove inwall
Touch.
Even more preferably, the side of described U-type groove is machined with the chamfering structure for being easy to static contact to slip into.
Even more preferably, the width of described U-type groove is not more than the thickness of the end of the static contact for slipping into.
Preferably, described static contact is fixedly mounted on shell by fixing screws.
Compared with prior art, the utility model has advantages below：
(1) using the set-up mode of dynamic/static contact of the present utility model, it is possible to reduce the quantity of dynamic/static contact, whole touching is made
Head apparatus structure is simplified.
(2) leading-out terminal only has one group of static contact, it is no longer necessary to conflux in addition so that cost is substantially reduced.
