Abstract
The utility model relates to a double thread screw lamp base and lamp holder, which is characterized in that a center post of the lamp base is provided with thread screw holes, and a center post of the lamp holder is provided with external screw threads. Due to the large area of electrical contact of the utility model, and therefore, the utility model has the obvious advantages of strong capacity of contact shock resistance; furthermore, the utility model can be used for electric light sources with strong shock and large power. The processing and the operation of the utility model are also convenient.
Description
The utility model relates to a kind of lamp holder, lamp base, refers to spiral lamp holder, lamp base especially.
Known spiral lamp holder, lamp base are used for the large power, electrically light source, are used for the violent places of concussion such as car, ship, high mast lighting, because the lamp holder anti-seismic performance is limited, cause the electric fault of loose contact easily.Be subjected to size restrictions, contact area is limited, and for the large power, electrically light source, contact resistance is bigger.
The purpose of this utility model is a kind of new scheme of design, improves the anti-seismic performance of lamp holder, increases lamp holder newel contact area.
The purpose of this utility model is achieved in that in the lamp holder newel outside guide groove, or the newel cross section is processed into squarely, and newel can only be stretched, and can not rotate; Be provided with screwed hole at the newel center, its size and supporting lamp base newel thread size adapt.
Because the contact of lamp holder, lamp base all is a thread connection, increased contact area on the one hand, reduced contact resistance; On the other hand, reduced the influence of concussion, strengthened anti-seismic performance, and the processing of this kind lamp holder, lamp base and use also are very easily electric contact.Be used for high-power, super high power electric light source, be used for outdoor lighting, be used for concuss places such as car, ship, advantage is obvious.
Below, in conjunction with the accompanying drawings and exemplary embodiments, the utility model is described in further detail.
Fig. 1 is novel lamp base schematic diagram, wherein: 1--lamp base newel; 2--lamp base screw thread.
Fig. 2 is the New-type lamp-holder profile, wherein: the 3--lamp holder base; The 4--spring leaf; The 5--lamp shell; The 6--screw sheel; 7--lamp holder newel; 8--screw sheel pin; 9--lamp holder newel screwed hole.
