Detailed description of the invention
Below by specific embodiment, the contact mechanism of a kind of switch described in the utility model is described in further detail.
nullSuch as Fig. 1，2，Shown in 3，A kind of contact mechanism of switch，Group is touched including the stationary contact group being used in conjunction with each other is dynamic with first、Second dynamic tactile group，Described stationary contact group includes static contact 1、First stationary contact 2 and the second stationary contact 3，First stationary contact 2 and the second stationary contact 3 are all fixedly installed in static contact 1，Described static contact 1 is fixedly installed on static terminal 4，First dynamic group of touching includes the first movable contact spring 5 and the first movable contact 6，The middle part of the first movable contact spring 5 is installed on first and moves support 7，First movable contact 6 is installed on the one end of the first movable contact spring 5，First movable contact 6 matches with the first stationary contact 2，Second dynamic group of touching includes the second movable contact spring 8、Second movable contact 9 and extension spring 12，The middle part of the second movable contact spring 8 is installed on second and moves support 10，Second movable contact 9 is installed on the one end of the second movable contact spring 8，Second movable contact 9 matches with the second stationary contact 3，First movable contact spring 5 and the second movable contact spring 8 side-by-side parallel are arranged，And first movable contact 6、Second movable contact 9 is respectively arranged in first movable contact spring 5 and the same side of the second movable contact spring 8，First moves support 7 and second moves support 10 and is mounted on moved end 11，Described extension spring 12 one end is fixedly installed on moved end 11，The other end of extension spring 12 is fixedly installed in the second movable contact spring 8 bottom and near the second movable contact 9，The other end of described first movable contact spring 5、The other end of second movable contact spring 8 coordinates with the first force section on the push-rod assembly of switch and the second force section respectively，Described push-rod assembly controls the first movable contact 6 and first connects with the second movable contact 9 with the first stationary contact 2 to the second stationary contact 3，Described push-rod assembly controls the first movable contact 6 and the first stationary contact 2 to the second stationary contact 3 and the second movable contact 9 separates evening，The most first connect and the realization of separation in evening is to be realized by the position of the first force section and the second force section，When i.e. pressing the first movable contact spring to make the first movable contact and the second movable contact connect under the first force section，Second force section still press against the other end of the second movable contact spring，Make the second stationary contact and the second movable contact also not in contact with，When push rod continues to move along，The second force section is just made to separate with the other end of the second movable contact spring，Now the second movable contact spring 8 makes the second stationary contact 3 contact with the second movable contact 9 under the effect of extension spring 12，And during physical cabling，First dynamic group touch group dynamic with second of touching is in parallel，And it is same，When push rod reversely retreats，Now the second force section can first press against the other end of the second movable contact spring，The second movable contact 9 and the second stationary contact 3 is made to separate，Now，First stationary contact 2 still contacts with the first movable contact 6，Therefore motor still conducting，When push rod is further continued for reversely retreating，First force section coordinates with the first movable contact spring makes the first movable contact 6 separate with the first stationary contact 2.
This contact mechanism also includes at the first dynamic pressing plate 13 touched between group and the second dynamic tactile group, this pressing plate 13 is installed on static terminal 4 and the top of moved end 11 and static terminal 4 and moved end 11 is pressed on the pedestal of switch, the fit structure matched with push-rod assembly it is additionally provided with on pressing plate 13, in the present embodiment, pressing plate 13 is L-shaped, pressing plate 13 includes horizontal plate face and vertical plate face, the horizontal plate face of pressing plate 13 and static terminal 4 and moved end son 11 equal compressive contact.Certainly, pressing plate 13 can also be the structure of other shapes.
Described fit structure includes the boss 131 being arranged on vertical plate face and the gathering sill 132 being arranged on horizontal plate face, this boss 131 is for installing the compression spring of push-rod assembly, described gathering sill 132 coordinates with the guide pad bottom push rod in push-rod assembly, in the present embodiment, described boss 131 is that cross is protruding, and this cross projection matches with the compression spring of push-rod assembly.
This contact mechanism also includes braking tactile group, the dynamic tactile group of brake, the brake stationary contact group that group includes cooperating is touched in described brake, the dynamic group of touching of brake includes the movable contact 14 that brakes, described brake movable contact 14 is installed on the other end of the first movable contact spring 5, brake stationary contact group includes the stationary contact 15 that brakes, described brake stationary contact 15 is installed on brake terminal 16, one end of described brake terminal 16 is installed on the pedestal of switch and is compressed by pressing plate 13, when the movable contact 14 that brakes contacts with brake stationary contact 15, group is touched in this brake can realize the fast braking of motor.
Described static contact 1 can be to use integrated mode with static terminal 4.
nullDuring use，By push rod 17 to the direction of the first movable contact 6 and the second movable contact 9 motion and under press，First movable contact spring is pressed for 5 times by push-rod assembly first with the first force section，First movable contact 6 moves closer to the first stationary contact 2 and contacts，First movable contact spring 5 is moving seesaw-type structure，First movable contact 6 contacts rapidly with the first stationary contact 2，Now switch connection，Due to the first dynamic tactile group、Second dynamic touching between group is in parallel，Achieve the rapid connection of switch，When push-rod assembly continues motion, the second force section separates with the other end of the second movable contact spring 8，Under the effect of extension spring 12，Second movable contact 9 is done step-by-step with the second stationary contact 3 and contacts，And due to the effect of trombone slide 12 after contacting，Second movable contact 9 and the second stationary contact 3 all-the-time stable firm contact，Adapt to macroseism environment，And when switch needs to disconnect，Push-rod assembly adverse movement，First the second movable contact 9 is separated with the second stationary contact 3，Then the first movable contact 6 is separated with the first stationary contact 2，Owing to both are in parallel，When only concurrently separating，Switch just disconnects，Therefore，After second movable contact 9 separates with the second stationary contact 3，When first movable contact 6 does not separates with the first stationary contact 2，Switch is still connected，When then waiting the first movable contact 6 to separate with the first stationary contact 2，Switch just disconnects，And the first movable contact spring is moving seesaw-type structure，Disconnect rapidly.
