Abstract

The utility model discloses a casing of an electronic ballast which is particularly applicable to outdoor illuminator. The utility model overcomes the disadvantages of the prior art that the prior casing of electronic ballast is poor in sealing and is not favorable to waterproof, and adopts the technology that the middle of the casing of an electronic ballast is designed into a hollow metal shell; two ends of the metal shell are sleeved with polymer shells made of dies, and the docking diameters of the polymer shells and the metal shell are matched; a plurality of line holes are opened at the outside of the polymer shells. Thus the utility model is good in heat dissipation, which avoids the aging of the wire caused by high temperature and prolongs the service life thereof. And the utility model has favorable sealing and waterproof effect, which is particularly applicable to illuminators in all outdoor environment.

Description

The electronic ballast shell

The utility model has related to a kind of electronic ballast shell, belongs to field of illuminating device.

Existing electronic ballast shell, it is assembled into convex shape by the metal of moulding, plastic material cutting as Chinese patent 99241387.7 disclosed " a kind of small-sized ballast shell ", because sealing is poor, is unfavorable for waterproof, be unsuitable for field uses such as lamp box advertisement out of doors.

The purpose of this utility model is to provide that a kind of technology is simple, cost is low, good heat dissipation, good sealing property is arranged, and is applicable to the waterproof electronic ballast shell of outdoor use.

The utility model ballast shell middle part is hollow metal-back, its two ends and the polymer shell socket of using Mold Making, and polymer shell docks bore with metal-back and matches, and the polymer shell outside has a plurality of lines hole according to the line number.

For better effect: between polymer shell and the metal-back with binding or/and the fixture bonding is fixing.

Seal with binding between the line hole in the polymer shell outside and the line.

Metal-back is adopted at the utility model middle part, helps distributing of heat, and electric wire and the internal electronic element of having avoided high temperature to cause are aging impaired, have prolonged its useful life; Two ends are with the polymer shell socket that bore matches, and add fixtures such as binding or screw and are bondd fixingly, have played good water-tight effect, help the all-environment out of doors use of lighting device.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model one embodiment cutaway view.

Fig. 2 is the polymer shell end view of the utility model one embodiment.

Embodiment 1

Make the hollow metal shell 1 at middle part, electronic ballast shell of aluminium alloy, its two ends are docked bore with polytetrafluoroethylene polymer shell 2 with Mold Making with metal-back 1 and are matched, both closely connect together, and fix with the binding glue bond, the polymer shell outside has a plurality of lines hole 3 according to the line number, after line passes from the hole, also with binding glue bond sealing.

Embodiment 2

Make the hollow metal shell 1 at middle part, electronic ballast shell of iron sheet, its two ends are docked bore with polyvinyl chloride polymer shell 2 with Mold Making with metal-back 1 and are matched, both closely connect together, and fix with the fixture screw, in its slit, fill binding glue, polymer shell 2 outsides have a plurality of lines hole 3 according to the line number, after line passes from the hole, also with binding glue bond sealing.
