Abstract
A sealing structure between a lamp housing and an electric wire comprises a lamp housing body, and is characterized in that an elastic sealing part is arranged and fixed on an opening portion on the back surface of the lamp housing body, the electric wire penetrates through the opening portion, and an electric wire hole which is arranged in the elastic sealing part and penetrated with the electric wire is in expansion sealing matching with the electric wire. The sealing structure is simple and reasonable in structure, few in component, fast in production and assembly and low in cost, and can meet requirements of electric wire penetrating of vacuum type energy-saving lamps.
Description
Technical field
The utility model relates to a kind of lamp housing hermetically-sealed construction.
Background technology
The patent No. is that 200410024951.9 Chinese patent is open and reported the vacuum energy-saving light fixture, this kind energy-saving lamp, it includes lamp casing, be mounted with luminous lamp body in the lamp casing, the lamp casing opening part is mounted with lampshade, it is characterized in that the space between described lampshade and the lamp casing is evacuated, its vacuum degree control at 40 millimetres of mercury height with interior scope; It is provided with aspirating hole at outer surface position described lamp casing, or lampshade is provided with aspirating hole in its outer surface position; Described aspirating hole is provided with automatic sealing device.
But defective is not report for the electric wire perforation structure, because lamp housing need be installed illuminating part, certainly will the electric wire in the external world need be extended to go in the lamp socket of lamp housing the inside, if do not solve the sealing problem of the electric wire perforation of lamp housing, the vacuum energy-saving light fixture still is an empty verbiage, so need do new improvement design.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of lamp housing of simple and practical, easy assembling use and the hermetically-sealed construction between the electric wire.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the hermetically-sealed construction between a kind of lamp housing and the electric wire, it comprises the lamp housing body, it is characterized in that the lamp housing body back side is mounted with elastic sealing element at the perforate position that places electric wire, the wire hole and the electric wire that are used for placing electric wire in the elastic sealing element are that tensioner is sealed and matched.
Described elastic sealing element sidepiece around it molds annular slot, is fixed on by draw-in groove on the perforate position at the lamp housing back side.
Described elastic sealing element is divided into independently each seal for many wires, and the annular slot of each seal by separately is connected in the perforate separately on the lamp housing body back side.
Described elastic sealing element is made integral seal spare for many wires, and integral seal spare is connected in the cooperation perforate at the lamp housing body back side by annular slot.
Described perforate position is to be arranged in the indent installation cavity at the lamp housing body back side.
Compared with prior art, advantage of the present utility model is: simple and reasonable, parts are few, and production and assembly are quick, and are with low cost, satisfy the needs of vacuum energy-saving light fixture electric wire perforation.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Examples of implementation 1
Illustrate as Fig. 1-2, hermetically-sealed construction between a kind of lamp housing and the electric wire, it comprises lamp housing body and lampshade, the crucial part of its invention is that lamp housing body 1 back side is mounted with elastic sealing element 2 at the perforate position that places electric wire, elastic sealing element 2 sidepiece around it molds annular slot 2.1, be fixed on by draw-in groove 2.1 in the perforate 1.1 at lamp housing body 1 back side, elastic sealing element 2 adopts rubber to make integral seal spare, 4 wire holes 2.2 that are used for placing electric wire have distributed, wire hole 2.2 diameters are slightly less than the diameter of electric wire, thereby making the wire hole 2.2 on the elastic sealing element is that tensioner is sealed and matched with electric wire, obtains sealing effectiveness.Last perforate 1.1 positions are to be arranged in the indent installation cavity 1.2 at lamp housing body 1 back side.
Examples of implementation 2
Anticipate as shown in Figure 3-4, hermetically-sealed construction between a kind of lamp housing and the electric wire, it comprises lamp housing body and lampshade, the crucial part of its invention is that lamp housing body 1 back side is mounted with elastic sealing element 2 at the perforate position that places electric wire, elastic sealing element 2 adopts rubber to make four seal 2a, each seal 2a sidepiece around it molds annular slot 2.1, and each seal 2a is distributed with a wire hole 2.2 that is used for placing electric wire, accordingly, four perforates 1.1 that distributed of perforate position, each seal 2a is fixed in each perforate 1.1 at lamp housing body 1 back side by draw-in groove separately, each seal 2a is connected in separately the perforate 1.1, wire hole 2.2 diameters are slightly less than the diameter of electric wire, are that tensioner is sealed and matched thereby make the wire hole 2.2 on the elastic sealing element 2 with electric wire, obtain sealing effectiveness.Last perforate position is to be arranged in the indent installation cavity 1.2 at lamp housing body 1 back side.
