Abstract
The utility model provides a safety screw lamp-cap without electrification, which is provided with a lamp head body and a lamp head cover. A wire connection post connected with the power supply, a lamp head leg contacting the bulb and screw thread for installing the bulb are installed in the lamp head body. The utility model is characterized in that a push rod is arranged in the lamp head body, and a moving wafer is connected to the push rod. One end of the moving wafer is matched with a wire connection post, and the other end thereof is connected with an electric conduction strip which is connected with the lamp cap leg, and a spring can be installed on the lamp head leg. The power supply of the utility model is transferred to the electric conduction strip through the wire connection post and the moving wafer, and then transferred to the bulb through the lamp head leg. When the bulb is not installed on the utility model, the lamp head leg is not electrified and is safe in use.
Description
The utility model relates to the incandescent lamp screw cap.
Existing incandescent lamp screw cap, the lamp holder pin at screw nut in its lamp holder and center is connected with the binding post of joining power all the time, therefore, when mains switch is opened, charged on lamp holder pin and the lamp holder nut, if being installed, do not run into because of carelessness by bulb, can cause electric shock accidents.Just in case bulb is installed turning on the power switch under the situation, also be very unsafe exactly.
The purpose of this utility model is that the nut of design in a kind of lamp holder is uncharged, the lamp holder pin in the lamp holder when bulb not being installed with the safe screw cap of binding post disconnection.
The utility model not technical scheme of charged safe screw cap is: body and lamp holder lid is arranged, the binding post and the lamp holder pin that contacts bulb of joining power are installed in the body, and the screw thread that bulb is installed, catch bar is arranged in body, interlock contact on the catch bar, of movable contact spring matches with binding post, and the other end of movable contact spring connects conducting strip, conducting strip links to each other with the lamp holder pin, or wherein a conducting strip links to each other with nut.
The not charged safe screw cap of the utility model has static contact under binding post, static contact matches with movable contact spring.On the lamp holder pin, regulating spring is installed.
Compared with the prior art not charged safe lamp holder of the present utility model, has safe in utilizationly, and when bulb not being installed, lamp holder pin and nut are not charged.
Fig. 1 is that the not charged safe screw cap screw thread of the utility model is the insulator schematic diagram;
Fig. 2 is that the not charged safe screw cap screw thread of the utility model is conduction nut schematic diagram;
Fig. 3 is the not charged safe screw cap movable contact spring vertical view of the utility model.
Describe embodiment of the present utility model in detail below in conjunction with Fig. 1-Fig. 3.
1, lamp holder lid; 2, binding post; 3, static contact; 4, movable contact spring; 5, conducting strip; 6, spring; 7, lamp holder pin; 8, catch bar; 9, body; 10, screw thread; 11, catch bar; 12, lamp holder pin; 13, conducting strip; 14, movable contact spring; 15, binding post; 16, nut; 17, conducting strip; 18, screw.
The utility model discloses not charged safe screw cap, lamp holder lid 1 and body 9 are arranged, the binding post 2,15 of joining power line is arranged in the body, binding post can be directly installed on the body, also can install by static contact 3.At the body center lamp holder pin 12 is arranged, lamp holder pin 12 cooperates with the bulb head, and lamp holder pin 12 can be positioned in the conducting strip 13, on regulating spring 6 is arranged, conducting strip 13 can be not cylindrical yet, connect the lamp holder pin under it, last interlock contact 14, movable contact spring are circular arc sheet metal (as shown in Figure 3), movable contact spring has catch bar 11 below 14 other ends, when people installed bulb, bulb up pushed up catch bar (insulator), and catch bar 11 is pushing away movable contact spring 14 and matching with binding post or static contact.When above-mentioned bulb is installed, another root catch bar 8 is also up pushed up (as shown in Figure 1), catch bar 8 is pushing away movable contact spring 4 and is matching with binding post 2 or static contact 3.The other end of movable contact spring 4 conducting strip 5 of ining succession, conducting strip connects lamp holder pin 7, and lamp holder pin 7 matches with the thread part of bulb, and regulating spring 6 is arranged on the lamp holder pin 7.This structure screw thread 10 only plays a part bulb is installed, and is non-conductive.And another kind of scheme as shown in Figure 2, is connected with conducting strip 17 by movable contact spring 4 without lamp holder pin 7, conducting strip 17 attaching nuts 16, nut 16 matches with the screw of bulb, like this, source current is through binding post 2, by movable contact spring 4, conducting strip 17, nut 16 to bulb.Movable contact spring the 4, the 14th, the circular arc sheet is installed in the body 9 by screw 18.
