Description

decorative lamp holder

technical field

The utility model relates to a lamp holder, in particular to a lamp holder for a decorative lamp or a holiday lamp which works in series.

Background technique

In the prior art, many low-voltage small bulbs of festival lights are lit simultaneously in series. Because it is a series circuit, as long as one or several bulbs are fused, the whole circuit is disconnected. To solve this problem, Chinese patent CN95226975.9 discloses a light bulb with a resistance wire, which can form a path through the resistance wire when the tungsten wire of the light bulb is fused, without affecting the normal operation of other light bulbs. There is also a bulb 001 with a fuse as shown in Figure 1 on the market now. A fuse 0011 is arranged between the two poles of the bulb 001. The fuse can be an aluminum wire with oxide skin. , due to the insulating effect of the oxide skin, no current flows through the fuse 0011. When the tungsten filament of the bulb is blown, because the resistance between the two electrodes of the bulb is infinite, a momentary high voltage appears between the two electrodes, and the high voltage breaks down the oxide skin of the fuse, making the fuse become a The permanent path between the two electrodes of a bulb. Fig. 2 is a known decorative lamp holder with resistance wire or fuse. The lamp holder 100 is composed of a wire 102 and a casing 101. The bulb 001 is connected to the wire 102 with a welding point 103 by welding. The resistance wires or fuses of the above two technologies are all arranged in the bulb, and when the bulb falls off, there will still be an open circuit, and the whole string of lights cannot be used.
