Abstract
The utility model discloses a kind of elevator hoistways light conduits, comprise main cable and many branch cables, described main cable is provided with many places branch node, and branch node comprises tie point and insulated tube, branch cable is connected with tie point, and insulated tube is wrapped in outside tie point.Described main cable comprises the branched trunk core being arranged side by side, and trunk core comprises metal inside and the insulated hull that is wrapped in metal inside, and described tie point is one section of exposed metal inside of having peelled off insulated hull.It is a kind of elevator hoistways light conduits reliable, that processing is loaded down with trivial details, not simple in structure that connects.
Description
Technical field
The utility model relates to elevator technology field, particularly a kind of elevator hoistways light conduits.
Background technology
In elevator field, all can use well lighting cable, elevator is the cable combination of carrying out illuminating lamp and the power supply control of control cubicle power supply box and transmission with well lighting cable, the operation principle of well lighting cable is to draw a cable laying in elevator hoistways by power supply box, the fixed position of specifying at cable makes tie point, and the conductor of the branch cable that illuminating lamp is drawn mode in accordance with regulations couples together.
At present, this well lighting cable all adopts closed end terminal to carry out the connection of wire conductor between cable, in the time adopting closed end terminal to connect, first the manual outer field ambroin shell of wire conductor that needs are connected divests, the conductor of electric wire snaps in the metal tube of closed end terminal inside after tightening mutually contact, then the metal tube of closed end terminal inside is compressed; Or in elevator erecting bed, wiring is laid in hoistway, then connection lighting.More than connect processing technology complexity, processing trouble, and also branch cable makes the conductor that the more multiplex cables of structural requirement carry out between cable and connects, thereby increased production cost, and waste resource, reduce operating efficiency.
Summary of the invention
Based on this, the purpose of this utility model is to overcome the defect of prior art, and a kind of elevator hoistways light conduits reliable, that processing is loaded down with trivial details, not simple in structure that connects is provided.
Its technical scheme is as follows:
A kind of elevator hoistways light conduits, comprises main cable and many branch cables, and described main cable is provided with many places branch node, and branch node comprises tie point and insulated tube, and branch cable is connected with tie point, and insulated tube is wrapped in outside tie point.
Described main cable comprises the branched core being arranged side by side, and core comprises metal inside and the insulated hull that is wrapped in metal inside, and described tie point is one section of exposed metal inside of having peelled off insulated hull.
Described branch node comprises multiple described tie points, and the quantity of described tie point is not more than the quantity of described trunk core.
Described branch cable comprises many branch cores, and the junction of branch core and tie point is also provided with metal band.
Described metal band is also provided with insulating tape outward.
In described insulated tube, be also filled with the PUR for sealing.
Advantage to aforementioned techniques scheme or principle describe below:
1, on main cable, designed dexterously branch node, separate branch cable from branch node and connect illuminating lamp, this branch node place does not need severing, choose suitable tie point but take to peel off the method that a bit of core insulated hull exposes metal inside, and can not affect the pulling force of main cable.
2, the branch core in branch cable and tie point achieve a fixed connection by the mode of copper strips crimping, and swathe insulating tape, thereby ensure safety and good laser propagation effect, and material cost easy to process is lower.
3, branch node place is also provided with insulated tube, is filled with seal hot melting glue in pipe, thereby makes branch cable 21 and main cable coupling part herein have good sealing, further guarantees safety and good laser propagation effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
As shown in Figure 1 to Figure 2, for a kind of elevator hoistways light conduits, comprise main cable 10 and many branch cables 20, branch cable 20 can external illuminating lamp, in main cable 10, comprise the branched trunk core 11 being arranged side by side, in branch cable 20, comprise branched branch core 21, trunk core 11 comprises metal inside and is wrapped in the insulated hull of metal inside, this main cable 10 is provided with many places branch node 16, each branch node 16 comprises multiple tie points 12 and insulated tube 15, here insulated tube 15 adopts the heat-shrink tube of insulation, the quantity of tie point 12 is not more than the quantity of trunk core 11, tie point 12 is the exposed metal inside of insulated hull that had peelling off of a bit of length, and this tie point 12 is connected with branch core 21, tie point 12 is wrapped up in copper strips 13 with the inner core connecting place of branch core 21, outside copper strips 13, wrap up in again with insulating tape 14, then after all tie points 12 all connect with branch core 21, wrap again with insulated tube 15 (in Fig. 2 for ease of mark and understand, therefore having vacated a tie point 12 is not connected with branch core 21), gap outside contacting with cable in insulated tube 15 is filled with seal hot melting glue.
As shown in Figure 3, the elevator hoistways light conduits described in the present embodiment is being laid after elevator hoistways, just can be by control cabinet power supply box 31 and power supply box 32 control circuit break-makes.
The advantage that the present embodiment has is as follows:
1, on main cable 10, designed dexterously branch node 16, separate branch cable from branch node 16 and connect illuminating lamp, these branch node 16 places do not need severing, choose suitable tie point but take to peel off the method that a bit of core insulated hull exposes metal inside, and can not affect the pulling force of main cable 10.
2, the branch core 21 in branch cable achieves a fixed connection by the mode of copper strips crimping with tie point 12, and swathes insulating tape 14, thereby ensures safety and good laser propagation effect, and material cost easy to process is lower.
3, branch node 16 places are also provided with insulated tube 15, are filled with seal hot melting glue in pipe, thereby make branch cable 21 and main cable 10 coupling part herein have good sealing, further guarantee safety and good laser propagation effect.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
