Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp assembly technology, specifically relating to a welding fit structure between a halogen lamp and a lamp holder. Background Technology

[0002] Halogen lamps are a common type of lighting in daily life. There are many types of halogen lamps, and different lamp holders are needed to fix them according to different specifications. Some halogen lamps use a structure in which they are directly inserted into a rectangular lamp holder and electrically connected to the lamp holder and the pin. The lamp body has two lamp feet. One lamp foot is welded to one end of the pin located below the lamp holder, and the other lamp foot is welded to a solder joint formed on the lamp holder. However, during the welding process, it was found that because the thickness of the pin is much greater than the thickness of the lamp holder shell, and the wall of the lamp holder at the solder joint position is also relatively thin, when pressure is applied to the lamp foot and the pin for welding, the lamp foot is very stable and there will be no cold solder joint. However, when pressure is applied to the solder joint on the lamp holder for welding, the position of the solder joint often shifts away from the side where the pressure is applied, which may cause cold solder joint between the lamp foot and the solder joint formed on the lamp holder, resulting in an increased defect rate of the manufactured halogen lamps.

[0003] In view of the above, it is necessary to design a simple welding structure for halogen lamps and lamp holders that can stably weld the lamp holder and lamp base. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0004] The objective of this invention is to provide a welding fit structure between a halogen lamp and a lamp holder, which helps to improve the lamp holder structure, making the welding between the lamp holder and the lamp base more stable and avoiding the occurrence of incomplete welds, thereby reducing the defect rate in halogen lamp processing.

[0005] The present invention achieves its objective as follows: a welding and fitting structure for a halogen lamp and a lamp holder, comprising a lamp body and a lamp holder, wherein one end of the lamp body forms a lamp body socket, and the lamp body is inserted into the lamp holder through the lamp body socket; a fixed window is respectively opened on the front and rear sides of one end of the lamp holder, and a fixed locking foot is respectively bent towards each other on the two sides of the two fixed windows, the fixed locking foot clamping the front and rear sides of the lamp body socket; a pair of lamp feet are provided at the lower end of the lamp body; the lamp holder is characterized by having a welding window respectively opened below the two fixed windows, and a lamp holder welding foot is respectively provided on the upper edge of the welding window; the two lamp holder welding feet are bent towards each other and arranged in parallel to form a clamp shape; one of the lamp feet is inserted between the two lamp holder welding feet and is clamped before being welded and fixed.

[0006] In a specific embodiment of this utility model, a filament is provided in the lamp body, and a pair of molybdenum plates are provided in the lamp body socket. The filament feet at both ends along the length of the filament are respectively connected to the upper end of a molybdenum plate on the corresponding side. The lamp feet are respectively connected to the lower ends of the two molybdenum plates, and the lamp feet extend out of the lamp body socket. A pin is provided at the lower end of the lamp holder, and an insulating sleeve is provided between the pin and the lamp holder. One end of the pin extends downward out of the lamp holder, and the other end passes upward through the insulating sleeve to form a pin welding foot. The other lamp foot of the pair is welded and fixed to the pin welding foot.

[0007] In another specific embodiment of this utility model, the lamp holder is a hollow cuboid structure that runs vertically through the body.

[0008] In another specific embodiment of this utility model, the insulating sleeve is made of ceramic material.

[0009] In another specific embodiment of this utility model, the lamp holder has a fixed groove punched at a position corresponding to the front and rear sides of the insulating sleeve.

[0010] In another specific embodiment of this utility model, a lamp body socket has a lamp body socket slide bar protruding from the edge of the front and rear sides, and the lamp body socket slide bar rubs against the inner wall of the lamp holder during the process of inserting the lamp body socket into the lamp holder.

[0011] The present invention has the following advantages due to the above-mentioned structure: by adopting a structure in which a pair of lamp holder welding feet are formed on the lamp holder for clamping and welding, it can avoid the lamp holder welding feet from shifting during the pressure welding process and causing incomplete welding, thus effectively reducing the defect rate of halogen lamp processing and saving production and labor costs.
