Abstract
The invention provides a clamping pin structure of an electrical element arranged on a guide rail. The clamping pin structure comprises an insulation shell, wherein the rear side surface of the insulation shell is provided with a fixed mounting pin and an elastic mounting pin which are respectively positioned on the upper and lower parts of the rear side surface of the insulation shell; the elastic mounting pin is of a cantilever shape, and the root part of the elastic mounting pin is fixedly connected to the rear side surface of the insulation shell; the elastic mounting pin is extended from the root part to the lower part of the insulation shell and then is extended toward the rear side of the insulation shell in an arc mode; the lower part of the rear side surface of the insulation shell is backwards provided with a spacing bulge; the spacing bulge is opposite to the external arc surface of the steering part of the elastic mounting pin, and a gap is formed between the spacing bulge and the external arc surface of the steering part of the elastic mounting pin; the steering part of the elastic mounting pin is arc-shaped, so that stress concentration in operation is reduced, the elasticity is ensured, the clamping pin structure can deform easily during operation, less in breakage possibility, large in movement range and convenient in mounting operation, and the spacing bulge can be used for preventing over-deformation of the elastic mounting pin.
Description
Technical field:
The present invention relates to electric field, relate in particular to low-voltage electrical apparatus, particularly a kind of fastener structure of the electric component of installing on guide rail.
Background technology:
Low-voltage electrical element for example circuit breaker, lightning guard, residual current operated protective device extensively adopts rail mounting structure.The rear side of the insulation shell of this type of low-voltage electrical element is provided with two plastic mounting pin, two plastic mounting pin lay respectively at the top and the bottom of insulation shell rear side, can close with the checkpost up and down of guide rail respectively, one of them plastic mounting pin adopts cantilever design and has elasticity, after this plastic mounting pin stress deformation, can increase two distances between plastic mounting pin, be convenient to plastic mounting pin and engage with guide rail.After plastic mounting pin engages with guide rail, plastic mounting pin, under elasticity restitution, applies active force to guide rail, prevents that insulation shell from coming off from guide rail.In prior art, this adopts the plastic mounting pin of cantilever design to be first parallel to insulation shell trailing flank to downward-extension, in right angle mode, turn to the rear of backward insulation shell to extend again, too concentrated at its right-angle steering place stress, easily fracture, and the scope of activities of the rear end of this plastic mounting pin is little, the distance increasing between two plastic mounting pin is limited, so inconvenient operation.
Summary of the invention:
The object of the present invention is to provide a kind of fastener structure of the electric component of installing on guide rail, the plastic mounting pin of employing cantilever design that the fastener structure of the described this electric component of installing on guide rail will solve the insulation shell rear side of prior art mesolow electric component easily fractures, scope of activities is little, the technical problem of inconvenient operation.
The fastener structure of this electric component of installing on guide rail of the present invention, comprise an insulation shell, on the trailing flank of described insulation shell, be provided with a fixed installation pin and an elasticity installation foot, described fixed installation pin and elasticity installation foot lay respectively at the upper and lower of insulation shell trailing flank, wherein, described elasticity installation foot is cantilever-shaped, the root of elasticity installation foot is fixedly connected on the trailing flank of insulation shell, elasticity installation foot first extends to the below of insulation shell from its root, with arc form, turn to the rear of backward insulation shell to extend again, the bottom of insulation shell trailing flank is rearward provided with a spacing preiection, the exterior arc surface of the turning part of described spacing preiection and elasticity installation foot in opposite directions and be provided with a gap.
Further, elasticity installation foot is provided with a breach in the extension at insulation shell rear, in described fixed installation pin, be also provided with a breach, the breach in elasticity installation foot extension is arranged in a plane that is parallel to insulation shell trailing flank in opposite directions and all with the breach in fixed installation pin.
Operation principle of the present invention is: elasticity installation foot first extends and turns to the rear of backward insulation shell to extend with arc form to the below of insulation shell from its root, stress while having reduced operation is concentrated, can guarantee the elasticity of elasticity installation foot, easily deformable when operation, frangibility not, the scope of activities of elasticity installation foot increases, and facilitates fitting operation, the bottom of insulation shell trailing flank rearward arranges spacing preiection, can prevent elasticity installation foot excessive deformation.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention is arranged to circular arc by the steering structure of the elasticity installation foot of insulation shell rear side, and the stress while having reduced operation is concentrated, and can guarantee the elasticity of elasticity installation foot, easily deformable when operation, frangibility not, the scope of activities of elasticity installation foot increases, and facilitates fitting operation.Meanwhile, in the bottom of insulation shell trailing flank, spacing preiection is rearward set, can prevents elasticity installation foot excessive deformation.
Accompanying drawing explanation:
Fig. 1 is the structural representation of the fastener structure of a kind of electric component of installing on guide rail of the present invention.
