Abstract

The utility model relates to a novel guide rail for a lamp power supply. The guide rail is made of thermoplastic fire-retardant insulative materials, and a pair of conduction laths covered by insulating layers are embedded in the guide rail. Connecting screws for wiring or lengthening are arranged on both ends of each conduction lath. Because a spring clamp type lamp connector is adopted, the connecting screws tightly contact the conduction laths in the guide rail by spring copper sheets. The guide rail for a power supply effectively overcomes the defect of the bad contact of the existing guide rail for a lamp power supply; the power of a lamp can be increased to hundreds of watts or thousands of watts; the utility model can be arbitrarily lengthened or bent into arbitrary shapes without adding a connector.

Description

The lamp power guide rail

The utility model relates to guide rail and the connector thereof that power supply is provided to light fixture.

The employed power rail of light fixture is all made with the aluminium alloy extrusions of rigidity at present, embeds the plastics row culture insulating barrier of a pair of trough of belt, and interior logical bare copper wire is made electric conductor.Light fixture radially contacts the acquisition power supply by the copper sheet end of connector with conductor wire.Because contact-making surface is little, it is little to bear power, and every light fixture at most can only tens watts.Simultaneously,, cause loose contact easily, even the generation arc spark burns out light fixture because contact is not tight.In addition, guide rail needs to use complicated special connecting piece to connect at lengthening or when turning, and its angle of bend limits because of being subjected to the connector shape, only 90 spend about, and can not curve curve shape, thereby cause very big restriction and inconvenience in actual applications.

The purpose of this utility model provides a kind of novel lamp power guide rail, and it not only can overcome the defective of existing lamp power guide rail loose contact, increases bearing power, and need not to add in addition connector and can extend arbitrarily or bend to arbitrary shape.

The utility model is achieved in that power rail comprises guide rail, electric conductor, light fixture connector and supporting member, guide rail is made with the thermoplastic flame-retardant insulating material of tool, be embedded with the conduction lath of a pair of external application insulating barrier, conduction lath two ends are provided with the connecting screw of wiring or lengthening usefulness.Adopt the light fixture connector of spring clip type, closely contact with conduction lath in the guide rail by spring copper sheet.

Because guide rail of the present utility model has thermoplasticity, thereby when installing, only need to use simple heating mode (soak as hair dryer, boiling water etc.) heating a moment, it can be bent to needed arbitrary shape, so that light fixture is combined into different patterns to intending crooked position.As the need lengthening, then can utilize the connecting screw of rail end to plug into into random length.Simultaneously because the utility model adopts the light fixture connector of spring clip type, spring copper sheet is pressed on the interior conduction lath of guide rail by the elastic force effect, contact-making surface is big and closely, not only avoided the generation of arc spark effectively, and lamp power can be increased to hundreds of watts to last kilowatt.

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is the partial enlarged drawing of power rail;

Fig. 3 is a light fixture connector structure chart;

Fig. 4 is the schematic diagram that the light fixture connector cooperates with guide rail;

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

With reference to Fig. 1, Fig. 2, power rail is made up of guide rail 1, conduction lath 2, connecting screw 4, light fixture connector 8, supporting member 7.Material extrusion moldings such as guide rail 1 usefulness flame-proof ABS engineering plastics or fire-retardant polyethylene, polyvinyl chloride, polystyrene, polypropylene, Merlon are shaped, and its cross section is the II font of approximate Roman number.Be embedded in the conduction lath 2 of external application insulating barrier 3 in the guide rail grooves on two sides.Connecting screw 4 is equipped with at conduction lath two ends, and the outside is surrounded by the insulation sealed piece 5 that can be connected with supporting member 7.Sealed piece 5 comprises and seals sleeve pipe 9, demarcation strip 6 and cover 13.Sealing sleeve pipe 9 matches with the outer wall of guide rail 1.Sealing the sleeve pipe upper end has hollow screwed pipe to be connected with supporting member 7, and its hollow hole is used for penetrating power line.Demarcation strip 6 inserts the hollow part of guide rails, and matches with the guide rail inwall.The effect of sealed piece 5 is to make the interior two conduction laths of guide rail seal fully, separate behind wiring or lengthening, to guarantee Electrical Safety.Cover 13 and after set of rails is dressed up Len req, make sealed at both ends usefulness.Supporting member 7 is made up of the hollow pipe and the base of TBE (threaded both ends), makes with insulating material.By supporting member 7, can be suspended to guide rail under the ceiling or on the floors such as stage, sales counter, also can vertically be loaded on wall, the post.

With reference to Fig. 3, Fig. 4, light fixture connector 8 by shell 12, inner casing 11, and two spring copper sheets 10 formed.Spring copper sheet 10 is made arc, is loaded in the housing of being made up of inside and outside shell.Inner casing 11 cooperatively interacts with shell 12, and is provided with guide vane end stop, drops out from shell to prevent inner casing.Have dividing plate to be separated into both sides in the middle of the inner casing 11, every limit embeds a spring copper sheet 10.Shell 12 two ends have in order to put into the breach of guide rail.After guide rail was pressed into along the shell breach, inner casing was depressed to spacing place by guide rail, and spring copper sheet is stopped by outer casing inner wall, inwardly was depressed into the conduction lath of guide rail both sides.Because it is crooked behind the spring copper sheet pressurized, produce elastic force, copper sheet can closely be contacted with the conduction lath and area big (the conductive plate bar insulation layer at this place scrapes off before installing), make copper sheet that shell is produced reaction force on the other hand again, add the double action of light fixture gravity, connector is fastened on the guide rail.Externally threaded hollow hole is with in the lower end of light fixture connector inner casing 11, and in order to connect light fixture, lamp power cord then passes hollow hole and compressed by spring copper sheet.
