Abstract

Disclosed is a dual-purpose safety lamp holder for screw and jack. An insulated casting is respectively provided with a capping, a connection base and a sheath from top to bottom. The connection base is fixedly equipped with a couple of power line terminals. The utility model is characterized in that a conductive sheath is arranged at the inner-around of the sheath, the lower segment of the conductive sheath is provided with a helical casing matching with the screw holder and upper segment of the conductive sheath is provided with a jack casing matching with the socket bulb. The jack groove on the jack casing directly is penetrated the helical casing, the notch of the jack groove is arranged on the bottom port of the helical casing. In the conductive sheath, the connection base is respectively equipped with an offest electrode and a peripheral electrode which are correspondingly connected with a couple of power line terminals, and the peripheral electrode is electrically connected with the conductive sheath. In terms of position, the offest electrode and the peripheral electrode not only correspond to a bipolar electrode of the socket bulb, but also the offest electrode corresponds to a center electrode of the screw bulb. The utility model is generally and conveniently applied to the screw bulbs and socket bulbs.

Description

Screw socket socket dual-purpose safe lamp holder

Technical field:

The utility model relates to the lamp holder in the lighting device.

Background technology:

Existing lamp holder for people to use has two kinds of screw socket and sockets, is special lamp cap, and corresponding illuminator lamp bubble also is divided into two kinds of screw socket and sockets, mutually can not be general.People often run into such inconvenience when urgent need: the inapplicable socket lamp holder of screw-socket bulb is arranged, or the inapplicable screw cap of socket lamp holder is arranged, make troubles for people's daily life.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of screw socket socket dual-purpose safe lamp holder is provided, so that two kinds of bulbs of screw socket and socket can be general on a kind of lamp holder, bringing convenience to daily life.

The technical scheme that the utility model technical solution problem is adopted is:

The utility model adopts insulation casing, and described insulation casing is respectively block, wiring pedestal and sheath from top to bottom, fixedly installs a pair of power-line terminal on described wiring pedestal.

Design feature of the present utility model is week conductive sleeve to be set in described sheath, the thread bush of described conductive sleeve hypomere for matching with screw cap, epimere is the socket cover that cooperates with socket bulb, and the socket groove that described socket puts runs through on thread bush, and its notch is positioned at the end mouth of thread bush; In described conductive sleeve, be positioned at the offest electrode and the periphery electrode that are provided with on the wiring pedestal respectively with the corresponding connection of a pair of power-line terminal of wiring pedestal, wherein, the periphery electrode is electrically connected with conductive sleeve, on the position, described offest electrode and periphery electrode are both corresponding to the bipolar electrode of socket bulb, also with the central electrode of its offest electrode corresponding to screw-socket bulb.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model can optionally be used screw socket and socket bulb, greatly convenient the use.

2, the utility model is simple in structure, safe and reliable.

3, the utility model is widely used in the circuit of the following various electric pressures of 380V-220V, be applicable to messenger wire lamp holder, short footlights head, Waterproof lampholder and small-sized, special lamp is first-class.

Fig. 1 is the utility model structural representation.

Fig. 2 is offest electrode and a periphery electrode position schematic diagram in the utility model.

Fig. 3 is the utility model conductive sleeve structural representation.

Number in the figure: 1 block, 2 wiring pedestals, 3 sheaths, 4 power-line terminals, 5 conductive sleeves, 6 socket grooves, 7 offest electrodes, 8 periphery electrodes.

Embodiment:

Referring to Fig. 1, present embodiment adopts insulation casing, and insulation casing is respectively block 1, wiring pedestal 2 and sheath 3 from top to bottom, fixedly installs a pair of power-line terminal 4 on wiring pedestal 2.

Shown in Figure 1, sheath 3 conductive sleeve 5 is set in interior week, the thread bush of conductive sleeve 5 hypomeres for matching with screw cap, epimere is the socket cover that cooperates with socket bulb, the socket groove 6 that socket puts runs through on thread bush, and its notch is positioned at the end mouth (shown in Figure 3) of thread bush.

Shown in Fig. 1,2, in conductive sleeve 5, be positioned at the offest electrode 7 and the periphery electrode 8 that are provided with on the wiring pedestal 2 respectively with a pair of power-line terminal 4 corresponding connections of wiring pedestal, wherein, periphery electrode 8 is electrically connected with conductive sleeve 5, on the position, as shown in Figure 2, offest electrode 7 and periphery electrode 8 are both corresponding to the bipolar electrode of socket bulb, also with the central electrode of its offest electrode 7 corresponding to screw-socket bulb.

In concrete the enforcement, should suitably distribute on the position offest electrode 7 and periphery electrode 8 make it accurately to contact safely and reliably with the electrode of screw-socket bulb and socket bulb.The concrete setting comprises: periphery electrode 8 is electrically connected with conductive sleeve 5, be positioned at periphery, offest electrode 7 suitable off-centre are positioned at week, must guarantee in the voltage security distance range between periphery electrode 8 and the offest electrode 7, tool ensures that bulb reliably contacts with lamp holder electrode, and contact area is at 5mm ²More than.

In addition, whole insulation casing should guarantee no any electric conductor exposure, the neat appearance in the lamp holder.

During concrete the use, screw-socket bulb and socket bulb all and between the lamp holder are all installed in the usual way.

According to above setting, withstand voltage design of the present utility model is applicable to the circuit of 380-220V and following all electric pressures, and the power of making illumination or indication usefulness is that 500W is following, the electrode safe distance is more than the 8mm, meets the safe distance requirement.
