Abstract
The utility model discloses a multi-hole protective ring which belongs to the technical field of electrical equipment parts. The protective ring is characterized in that the main structure is a multi-hole collar; both ends of the multi-hole collar are provided with inner flanges and outer flanges; the middle object of the multi-hole collar is axially provided with a set of wire hole; the wire hole is conical with the diameter of the inner end larger than the diameter of the outer end. The multi-hole protective ring has novel design and reasonably structure; in the structure adopting the protective ring, wires and cables can go through the wire hole in a closed way, which prevents the wires and the cables from shaking, and steam, fog, hazardous gas or foreign matter from entering into the equipment, thereby improving the protection level of the electric appliance equipment, increasing the thickness of the multi-hole protective ring between the lead wire and a frame, improving the mechanical safety performance and electrical safety performance as well as the tensile resistance of the lead wire.
Description
Technical field
The utility model belongs to electric equipment accessory technical field, is used to protect the Porous Coil-Protecting ring of electric wire when being specifically related to a kind of electric wire cross-under by casing for electric appliances.
Background technology
In electric equipments such as household electrical appliance, motor, electric tool, power line isoelectric line cable usually is that cross-under is drawn by the fairlead that is provided with on the electrical equipment shell, and Porous Coil-Protecting ring of clamping prevents that to separate lead-in wire and casing electric wire from rocking, preventing that electric wire from being hurt and preventing that foreign matter is from the fairlead access arrangement on fairlead.The Porous Coil-Protecting ring that generally adopts is the structure of the hollow ring body of cylindricality two ends arranged outside rib at present, and electric wire is drawn from hollow ring body.In the use, cross-under and between the electric wire crossed, still have certain clearance between electric wire and the hollow ring body, the less foreign matter of steam, cloud, pernicious gas or particle still enters easily, can destroy internal insulating layer, reduce the degree of protection of electrical equipment, foreign matters such as particle enter motor, electric tool inside, also cause motor rotation blockage easily.Outside two, the cavity ring body structure of existing Porous Coil-Protecting ring makes that the outer wall support strength is relatively poor, and when being used for the protection of portable power source lines such as motor, electric tool, Porous Coil-Protecting ring wearing and tearing easily breaks.
The utility model content
The utility model aims to provide a kind of Porous Coil-Protecting ring technical scheme based on porous collar, energy close-fitting lead-in wire, to overcome problems of the prior art.
Described Porous Coil-Protecting ring, it is characterized in that agent structure is a porous collar, limit, porous collar two ends is equipped with inner retaining side, outer rib, and one group of fairlead axially is set on the intermediate entities of porous collar, described fairlead is a bellmouth, and its inner diameter is greater than the outer end diameter.
Described Porous Coil-Protecting ring is characterized in that described one group of fairlead is 2～6.
Described Porous Coil-Protecting ring it is characterized in that described outer rib, inner retaining side are circular configuration, and outer rib diameter is greater than the inner retaining side diameter.
Described Porous Coil-Protecting ring is characterized in that cylindrical body porous collar and inner retaining side, the outer rib structure that is formed in one.
Described Porous Coil-Protecting ring is characterized in that adopting the one-body molded formation of rubber or engineering plastics.
Above-mentioned Porous Coil-Protecting ring is novel, rational in infrastructure, adopt the protective ring of this structure, electric wire can airtight cross-under from fairlead, can prevent that cable from rocking, prevent steam, cloud, pernicious gas or foreign matter access arrangement inside, improve the degree of protection of electric equipment, the Porous Coil-Protecting ring thickness between lead-in wire and the casing increases, machine security performance and electrical safety performance can be improved, and the resistance to tension of lead-in wire can be improved.

Among the figure: 1-inner retaining side, 2-porous collar, the outer rib of 3-, 4-fairlead.
Embodiment
Now, describe embodiment of the present utility model in detail in conjunction with Figure of description:
As shown in the figure, the agent structure of Porous Coil-Protecting ring is a porous collar 2, and limit, porous collar 2 two ends is equipped with inner retaining side 1, outer rib 3, by inner retaining side 1, outer rib 3 protective ring is connected on the apparatus casing, inner retaining side 1 is in housing, and outer rib 3 is outside housing.Outer rib 3, inner retaining side 1 are circular configuration, and outer rib 3 diameters are convenient to the slave unit outside protective ring is snapped in greater than inner retaining side 1 diameter.One group of fairlead 4 axially is set on the intermediate entities of porous collar 2, and fairlead 4 is generally 2～6, can increase or reduce according to number of leads.Described fairlead 4 is a bellmouth, its inner diameter is greater than the outer end diameter, and the line that is connected footpath is between the aperture, two ends, and lead-in wire closely cooperates with the fairlead inwall in the outer end, can prevent effectively that lead-in wire from rocking, and prevents steam, cloud, pernicious gas or foreign matter access arrangement inside.Described cylindrical body porous collar 2 and inner retaining side 1, outer rib 3 structure that is formed in one adopts rubber or the one-body molded formation of engineering plastics.
