Abstract
A clamping foot structure for installing an electrical element on a guide rail is disclosed. The clamping foot structure comprises an insulation shell body, the rear side face of the insulation shell body is provided with a fixed installation foot and an elastic installation foot, the fixed installation foot and the elastic installation foot are respectively positioned at the upper part and the lower part of the rear side face of the insulation shell body, the elastic installation foot is shaped like a cantilever, the root part of the elastic installation foot is fixedly connected onto the rear side face of the insulation shell body, the elastic installation foot extends from the root part thereof firstly to a position below the insulation shell body, then the elastic installation foot extends to a position behind the insulation shell body after changing direction in a circular arc manner, a limiting protrusion is arranged backwards at the lower part of the rear side face of the insulation shell body, the limiting protrusion and the outer circular arc surface of a direction change part of the elastic installation foot face toward each other, and a gap is arranged between the limiting protrusion and the outer circular arc surface. The direction change part of the elastic installation foot is arc in shape, stress concentration in operation processes can be reduced, elasticity can be ensured, the direction change part is easy to deform in operation processes and is not easy to break, a moving range is increased, and convenience for installation and operation is realized. Excessive deformation of the elastic installation foot can be prevented by the limiting protrusion.
Description
Technical field:
The utility model relates to electric field, relates 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 adopt 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, turn to the rear of backward insulation shell to extend in right angle mode 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, therefore inconvenient operation.
Summary of the invention:
The purpose of this utility model is to provide a kind of fastener structure of the electric component of installing on guide rail, and the plastic mounting pin that the fastener structure of the described this electric component of installing on guide rail will solve the employing cantilever design of 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 utility model, 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, turn to the rear of backward insulation shell to extend with arc form 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 utility model 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 in the time of operation, not frangibility, 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 utility model and prior art are compared, and its effect is actively with obvious.The steering structure of the elasticity installation foot of insulation shell rear side is arranged to circular arc by the utility model, and the stress while having reduced operation is concentrated, and can guarantee the elasticity of elasticity installation foot, easily deformable in the time of operation, not frangibility, 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 the electric component of installing on guide rail of the present utility model.
