Abstract
A combined alternately positioned layer flame-retarding device comprises a flame-retarding spring, an upper barrier plate, a lower barrier plate, a sliding cover, a cover spring and a positioning pin. The two ends of the flame-retarding spring are fixed on the upper and the lower barrier plates respectively to make the two barrier plates in alternate positions so as to retard flame. The sliding cover is arranged at the position having a larger hole-diameter and can slide along a path limited by the upper and the lower barrier plates by pressing the cover spring. When a contacting element is removed, the two barrier plates are alternately positioned under action of the flame-retarding spring and the sliding cover covers the hole under action of the cover spring; thus flame-retarding of an electric connector with a large hole-diameters difference is achieved. The utility model has the advantages of simple structure, convenient operation, small volume, and high flame-retarding effect, and is suitable for electric connector of contacting elements with different sizes.

The flame preventing device of electric connector mainly contains staggered floor and two kinds of versions of layering, and wherein staggered floor construction is used comparatively extensive because of having characteristics such as the axial space that takies is little, simple in structure.Two fire resistant baffle plates of the general employing of its version, the position, hole on the dislocation backboard is blocked mutually, and passing through of blocking-up flame forms the protection to electric connector electric contacting part position.Because the displacement of dislocation is a fixed value, when the aperture size on the baffle plate is close, flame just can be blocked in the dislocation back, but have multiple contact specification simultaneously when electric connector, cause that the bigger position of dislocation back aperture just can not be blocked fully when aperture size on the baffle plate differed big, and exist the hole to stitch, flame just can pass flame preventing device, and ablation electric contacting part position causes the inefficacy of electric connector.In sum, existing staggered floor flame preventing device has multiple contact specification simultaneously at electric connector, causes when aperture size differs big, just can't block flame fully, does not have good fire resistant protective effect.
Three, summary of the invention
The purpose of this utility model is primarily aimed at the problem that staggered floor flame preventing device with multiple aperture size exists, and proposes the new construction of a kind of " compound staggered floor fire resistant ", the realization aperture size fire resistant function under the situation that differs greatly.
Compound staggered floor flame preventing device of the present utility model is made up of fire resistant extension spring, overhead gage, lower baffle plate, slide cover, cover spring and alignment pin.The fire resistant extension spring is an extension spring, one end and overhead gage are fixed, the other end and lower baffle plate are fixed, keep upper and lower baffle plate to be in the dislocation state, have only the fire resistant extension spring that stretches under external force, just can make position, the hole alignment of upper and lower baffle plate, after external force or obstacle are removed, upper and lower baffle plate continues to keep the dislocation state under the effect of fire resistant extension spring, shelters from the position, hole mutually, blocks passing through of flame.Because upper and lower baffle-plate misplacement only can shelter from close position, aperture mutually, the position that differs greatly in the aperture then specialized designs local flame preventing device.Local flame preventing device is made up of slide cover, cover spring and alignment pin; slide cover is in closure state under the effect of cover spring; all the time shelter from the position, hole that needs protection; promote slide cover; then compressible cover spring makes slide cover slide along the track that upper and lower baffle plate limits.In order to prevent the cover spring unstability, designed alignment pin, alignment pin and overhead gage install and fix, one end of cover spring is through on the alignment pin, the other end is then packed in the spacing hole of slide cover, make cover spring can finish promotion and support, when compression, unstable phenomenon can not take place again, realize operate as normal slide cover.In order to make compound staggered floor flame preventing device have operability, be designed to consistent with the direction that slide cover is pushed open the pushing direction of upper and lower baffle holes position alignment, and the external force of slide cover is pushed in utilization open, promote upper and lower baffle plate and make its position, hole alignment, slide cover is when pushing open like this, alignment has also been realized in the position, hole of upper and lower baffle plate, allows contact to pass flame preventing device.After contact was removed, upper and lower baffle plate is dislocation automatically under the effect of fire resistant extension spring, and slide cover also auto-closing under the effect of cover spring shelters from the position, hole that needs protection, and forms the blocking-up to flame.The same in the operation with existing staggered floor flame preventing device, realized one the step finish, have good operability.
Compound staggered floor flame preventing device of the present utility model, realized the fire resistant of the electric connector that the aperture size difference is bigger, have simple in structure, easy and simple to handle, volume is little, the blocking-up flame characteristics such as function admirable, be applicable to the fire resistant of the electric connector of multiple contact specification, have good application value.
