Fig. 1 is explosive view of the present utility model;
The schematic diagram that the guide post that Fig. 2 provides for the utility model coordinates with gathering sill:
Fig. 3 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the stable engaging means of a kind of switch contacts that the utility model provides mainly comprises switch enclosure 100, connecting rod 200, movable contact bridge contact apparatus 300, spring and fixed contact 500.
The shell of switch enclosure 100，Wei Ben mechanism, for settling connecting rod 200, movable contact bridge contact apparatus 300, spring and fixed contact 500 these parts, and protects these parts.
On switch enclosure 100, be provided with bar shaped resettlement groove 110, for settling connecting rod 200
Connecting rod 200, is specifically set to U-shaped shape, and in dismountable resettlement groove 110 that is placed in switch enclosure 100, it is for movable contact bridge contact apparatus 300 is fixed on the resettlement groove 110 of switch enclosure 100, and provides movement locus for movable contact bridge contact 300 devices.
Connecting rod 200 specifically by its top link 220 match with the draw-in groove 120 on switch enclosure 100 tops, in dismountable resettlement groove 110 that is vertically placed on switch enclosure 100, be convenient to like this connecting rod 200 fixing in resettlement groove 110, prevent when operation, connecting rod 200 is loosening in resettlement groove 110, impact effect.
At the middle part of connecting rod 200, open a U-lag 210 matching with itself shape, U-lag 210 is for settling spring and movable contact bridge contact 300 devices.
On U-lag 210 both sides, symmetry offers gathering sill 230, and gathering sill 230 is specifically comprised of several irregular circular curves, when guide pad 321 moves on gathering sill 230, can move according to the track of gathering sill 230.
Movable contact bridge contact apparatus 300, is placed in the U-lag 210 of connecting rod 200, and it is to be fixed in the resettlement groove 110 of switch enclosure 100 by connecting rod 200, and can in the resettlement groove 110 of switch enclosure 100, move forward and backward.
Movable contact bridge contact apparatus 300 comprises movable contact bridge contact 310 and guider 320.
Movable contact bridge contact 310 specifically can be arranged to strip, and the two ends in the middle of movable contact bridge contact 310 are symmetrically arranged with link 311, for the spring being fixedly attached thereto.
On guider 320, be also provided with guide pad 321, guide pad 321 is connected with the gathering sill 230 on U-lag 210, and guide pad 321 can move on gathering sill 230.
Fixed contact 500, the resettlement groove 110 both sides of symmetrical placement on switch enclosure, for being communicated with movable contact bridge contact 310.
Like this, movable contact bridge contact apparatus 300 moves on gathering sill 230 by guide pad 321, thereby move on the U-lag 210 of connecting rod 200, movable contact bridge contact 310 just can move forward and backward by connecting rod 200 in switch enclosure 100 like this, thus with fixed contact 500 UNICOMs that are arranged on resettlement groove 110 both sides.
Spring, comprise the first spring 400 and the second spring 410, be connected with the link 311 on movable contact bridge contact apparatus 300 respectively, and spring matches and is placed in the U-lag 210 of connecting rod 200 with movable contact bridge contact apparatus, can provide elastic force for the movable contact bridge contact apparatus 300 in U-lag 210 interior movements like this, after movable contact bridge contact 310 and fixed contact 500 Surface Contacts, on the motion track that guide pad 321 can provide at gathering sill 230, be fixed (referring to Fig. 2), spring can be stablized again contacting between movable contact bridge contact 310 and fixed contact 500 like this, prevent that movable contact bridge contact 310 is in the interior movement of U-lag 210, affect contacting between movable contact bridge contact 310 and fixed contact 500.
This mechanism utilizes guide pad 321 to go to connect disjunction by gathering sill 230 directions in connecting rod 200, and the contact surface that can reach moving contact 310 and fixed contact 500 is self-cleaning, reduces the contact resistance of oxidation, increases the service life, and reaches the stable object of signal code transmission.
The execution mode following (referring to Fig. 3) of this mechanism:
In distribution line transmission line, when the closed connection of auxiliary switch, spring utilizes bounce to promote guide post 330 and movable contact bridge contact 310 moves upward, on the running orbit of guide pad 321 meetings gathering sill 230 on connecting rod 200, move, after movable contact bridge contact 310 and fixed contact 200 Surface Contacts, guide pad 321 can arrive and stablize after conduction position along gathering sill 230, and switch contacts is connected, thereby reaches stable object.
