Improved lights for string of lights

Abstract

The disclosed improved lamp in use for lamp string includes following parts: shell; base holder; bulb including a pair of leader line of filament; being located at low part of base holder, first separator is extended downwards; a pair of terminal is extended to the shell, two pieces of spring terminal; and supporting block with hollow structure at upper part. Being fixed on the supporting block, two pieces of spring terminal are elastic contacted to each other. The supporting block is fixed inside the shell. The pair of terminal inside the shell is electrically connected to two pieces of spring terminal correspondingly. The supporting seat is extended from bottom of the supporting block. When bulb is put into the shell, low end of the first separator is contacted to or supported by the supporting seat. Second separator is extended from bottom of the supporting block. When bulb is not in socket, circuit is still kept on state. Features are: good safety and easy of assembly.

Description

technical field [0001] This invention relates to lamps for use in light strings, and more particularly to bulb bases for connection to sockets which will continue to conduct current even when one or more individual light bulbs are not in the socket and Keep the rest of the lights in the string glowing. Background technique [0002] Light strings having lights electrically connected in series are well known, especially around festive seasons, for decorative purposes. Typically, strings of lamps are electrically connected in series rather than in parallel. A particular disadvantage of this string of lights is that when the bulb is removed from the socket or the filament in the bulb is blown, the current cannot continue to flow through the socket due to the gap created in the socket, causing the bulbs in other series-connected sockets to fail. A circuit is formed that renders the entire series path inoperable. Only when a "good" bulb is plugged into a socket can a circuit be...

Problems solved by technology

But, although this invention is the reasonable representative of current prior art, still there is following deficiency: 1, be directly connected with terminal lead wire (wire) by spring terminal (when making, spring terminal is to be connected on the copper sheet wiring on terminal lead wire) After the terminal is extended and formed), the longer spring terminals often collude with each other, one is not easy to assemble, and the other is that the spring terminal is easily deformed during the assembly process, resulting in poor contact; 2. Because the wire is directly connected to the spring terminal connection, when the wire shakes, it directly affects the contact performance of the spring terminal

However, this invention still has room for improvement: 1. Since most of the light strings are used outdoors or in the open air, dewdrops will enter the lamp holder in humid weather, and the dewdrops hanging at the lower end of the spacer will easily cause a short circuit. security risk

2. This patent is more suitable for use when plugging between the light string and the socket. When connecting with a non-slot wire, there is still the problem of poor contact
