Abstract
The utility model relates to a single contact-bridge bilateral moving contact mechanism for s thumb-operated switch. The mechanism comprises a moving contact support and a contact bridge; the contact bridge (3) is arranged in the moving contact terminal support (1); bilateral moving contact terminals (4) are arranged on both ends of the contact bridge; moving contact pressure springs are arranged on the upper and lower surfaces at the center of the contact bridge; one end of the upper pressure spring (8) is arranged in a slip mass (2) and the other end is supported on the moving contact terminal support; the slip mass (2) is supported on positive stops (6) arranged on both sides of the inner wall of the moving contact terminal support; one end of the lower pressure spring (5) is contacted with the lower surface of the contact bridge and the other end is supported on the moving contact terminal support. In the utility model, one contact bridge acts as two contact bridges, therefore compared with the existing two-contact-bridge structure, the volume of the moving contact structure is evidently reduced and the requirement of the thumb-operated switch to the moving contact structure volume is effectively solved; furthermore the utility model is more reasonable in the structure and better in the working stability.
Description
One, technical field
What the utility model related to a kind of Push switch singly touches the two-way dynamic contact mechanism of bridge.
Two, background technology
At present, manually, the Push switch used on the electric tool, unidirectional moving contact and two-way dynamic contact mechanism are arranged, be suitable for the Push switch of difference in functionality.The utility model relates to a kind of two-way dynamic contact mechanism, background technology is characterized in adopting and twoly touches bridge construction as shown in Figure 1, and promptly two-way moving contact is distributed in two and touches on the bridge, and two are touched and settle compression spring between the bridge.The dynamic contact mechanism of this structure owing to use two to touch bridge, make that mechanism's volume is bigger, and cost is higher, certainly will influence Push switch and use such as optimizing on manual, the electric tool.
Three, summary of the invention
It is little that the utility model aims to provide a kind of volume, good stability, and the structure rational Push switch list that more becomes touches the two-way dynamic contact mechanism of bridge, to adapt to Push switch to dynamic contact mechanism volume and performance demands.
For achieving the above object, the technical solution adopted in the utility model is to replace existing two bridge construction that touches with the single bridge construction that touches, promptly in moving contact frame, be provided with one and touch bridge, touch the bridge two ends and be provided with two-sided moving contact, touch and settle upper and lower moving contact stage clip on the upper and lower faces of bridge centre, compression spring one end is arranged in gliding mass, the other end is bearing on the moving contact support body, gliding mass is bearing on the positive stop of moving contact support body inwall both sides, following stage clip one end in contact is touched the bridge lower plane, and the other end is bearing on the moving contact support body.When moving contact frame promotes, following stage clip compression, touch that corresponding fixed contact closely contacts in moving contact and the Push switch above the bridge, when the trip switch button, moving contact frame is nature, touch moving contact below the bridge under the compression spring effect with Push switch in corresponding fixed contact closely contact.
Because one of the utility model employing is touched bridge and is played two effects of touching bridge, touch bridge construction than existing two, obviously reduce the volume of dynamic contact mechanism, solved the requirement of Push switch effectively the dynamic contact mechanism volume, and structure more becomes rationally, and job stability is better.
Four, description of drawings
Fig. 1 is the two structural representations that touch the two-way dynamic contact mechanism of bridge of background technology.
Fig. 2 touches the structural representation of the two-way dynamic contact mechanism of bridge for a kind of embodiment list of the utility model.
Fig. 3 touches the two-way dynamic contact mechanism of bridge user mode schematic diagram in Push switch for the utility model list.
Five, embodiment
Fig. 2, Fig. 3 provide a kind of embodiment list of the utility model and touch the structural representation of the two-way dynamic contact mechanism of bridge and the state that this mechanism uses in Push switches.The present embodiment dynamic contact mechanism comprises moving contact frame 1 and touches bridge 3, be provided with one in the moving contact frame and touch bridge, touch the bridge two ends and be provided with two-sided moving contact 4, touch and settle upper and lower moving contact stage clip on the upper and lower surface in bridge centre, compression spring 8 one ends are arranged in gliding mass 2, and the other end is bearing on the moving contact support body, and gliding mass 2 is bearing on the positive stop 6 of moving contact support body inwall both sides, one end in contact of following stage clip 5 is touched the bridge lower plane, and the other end is bearing on the moving contact support body.Gliding mass 2 preferably is concave shape, and projection 7 is arranged at the bottom, and compression spring 8 one ends are positioned on the projection, touches the bridge centre and preferably is the Jiong shape, and following stage clip one end is positioned on the Jiong body.Can make upper and lower stage clip position more stable like this, make operating state more stable.
This dynamic contact mechanism is provided with hanging groove 9, and whole dynamic contact mechanism is connected with dynamic pressure spring support 11 in the Push switch 12 by hanging groove 9, and is installed in the Push switch.Moving contact frame adopts the are-tight plastic cement of high temperature insulation, the excess of stroke pressure of the elastic force of upper and lower stage clip and moving contact, open apart from be when this integral body in regulation moves up and down scope, by moving contact stage clip, the mutual motion decision of touching bridge and moving contact support body upper limit position block.In the moving contact frame to be positioned at the upper and lower moving contact 4 that touches on the positive and negative of bridge two ends corresponding with the fixed contact 10 on being fixed on the Push switch seat separately.
Claims (3)
