Abstract
The utility model relates to a shielded cable for an elevator encoder solving a technical problem that the provided cable can be applied to coordinate with anti-pull-off bayonet of an elevator encoder and having features of excellent high frequency insulating property, high abrasive resistance and corrosion resistance. The technical scheme is characterized in that: the shielded cable special for an encoder comprises a cable shield, a shielding layer, a cladding layer and a plurality of insulating cores, wherein the cable shield, the shielding layer and the cladding layer are arranged from outside to inside; the insulating cores are cladded by the cladding layer; the insulating core comprises a conductor and an insulating layer cladding the outer periphery of the conductor; the insulating layer is high density polyethylene; the shielding layer comprises an aluminum foil layer cladding the outer periphery of the cladding layer and a cooper wire braiding mesh cladding the outer periphery of the aluminum foil layer; and the cladding layer belongs to non-woven fabrics.
Description
Technical field
The utility model relates to a kind of cable, especially the shielded type cable of elevator own coding device.
Background technology
Elevator own coding device (claiming rotary encoder again) is the routine configuration of existing elevator, and its effect is that the revolution pulse through per second is write down the speed of service of elevator and fed back to control cubicle with elevator position.
The junction of existing elevator own coding device (being generally import parts) and shielded cable is provided with the anti-slip bayonet socket of standard, and this bayonet socket has strict requirement to the cable outside dimension.Yet,, can't adapt to the requirement of above-mentioned bayonet socket because external diameter is bigger than normal according to the cable of present shielded cable standard production.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that the above-mentioned background technology exists; A kind of improvement of elevator encoder shielded type cable is provided; This cable should be able to be used with elevator own coding device anti-slip bayonet fittings, and has high-frequency insulation function admirable, resistance to wear is good and corrosion resistance is strong characteristics.
The technical scheme that the utility model provides is: encoder private mask cable; Comprise from outside to inside cable cover(ing), screen, the integument that is provided with and several insulated wire cores that coated by integument, described insulated wire cores is by conductor and the insulating barrier that is coated on the conductor excircle; It is characterized in that described insulating barrier is a high-density polyethylene layer.
Described screen is made up of aluminium foil layer that is coated on the integument excircle and the copper wire mesh grid that is coated on the aluminium foil layer excircle.
Said integument is a nonwoven layer.
The beneficial effect of the utility model is: because the insulating barrier of the insulated wire cores of this cable adopts high density polyethylene (HDPE) (HDPE) material; Thereby can coat under all satisfactory prerequisite of continuity with insulation by online core insulation resistance; Significantly reduced the line footpath, and then realized and the effective fit applications of elevator own coding device anti-slip bayonet socket; Can also directly require to realize down the multiple-core of cable at the cable of regulation.The conventional PVC Insulation Material of HDPE has better wear resistance, corrosion resistance, the high-frequency insulation function admirable simultaneously.
Description of drawings
Fig. 1 is the cross-sectional structure sketch map of the utility model.
Embodiment
As shown in the figure; Encoder private mask cable; Comprise cable cover(ing) 1, screen 2, the integument 3 that is provided with from outside to inside and several insulated wire cores 4 that coat by integument; Described insulated wire cores is by conductor 5 and the insulating barrier 6 (clear for drawing, the hatching of insulating barrier omits) that is coated on the conductor excircle; Described screen is formed (clear for drawing, the hatching of insulating barrier also omits) by aluminium foil layer that is coated on the integument excircle and the copper wire mesh grid that is coated on the aluminium foil layer excircle.This is the conventional structure of encoder private mask cable.
Because the insulating barrier of existing cable adopts conventional PVC Insulation Material, thereby the line footpath can't reduce, thus can not with the supporting application of elevator own coding device anti-slip bayonet socket, the discontinuous phenomenon of insulation parcel appears simultaneously easily.
The improvement of the utility model is: change the original PVC Insulation Material that adopts of insulating barrier into the high density polyethylene (HDPE) material; The high-density polyethylene layer that forms thus can significantly reduce the line footpath satisfying under core insulation resistance and the successional prerequisite of insulation coating, enables and the supporting application of elevator own coding device anti-slip bayonet socket; In addition, also can realize multiple-core (16 cores of demonstration among the figure of cable; Also can increase core quantity as required).
Said integument adopts nonwoven fabrics to make usually, forms nonwoven layer.
The utility model manufacturing is also identical with existing cable, and what just adopt in the injection molding machine is high density polyethylene (HDPE) material (but not PVC Insulation Material).
