Description

Technical Field

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

[0002] Halogen lamps are high-efficiency incandescent lamps based on the halogen tungsten cycle principle. Their core structure includes a quartz glass shell, a tungsten filament, and halogen gas. When the filament is energized, it emits light at high temperatures. The evaporated tungsten combines with the halogen gas to form tungsten halide, which is then re-deposited on the filament surface through a cycle, thereby slowing down tungsten filament wear and improving luminous efficiency. Their compact size, high brightness, and color temperature stability make them widely used in automotive headlights, industrial lighting, and other fields.

[0003] There are many types of halogen lamps. One type of halogen lamp is directly plugged into a lamp holder. One of the two lamp legs of the halogen lamp is connected to the lamp holder, and the other is connected to a socket that is insulated and fixed to the lamp holder. The lamp holder usually has inwardly bent claws, which guide and fix the lamp body. The corresponding lamp body needs to be provided with guide grooves for cooperating with the claws. During the insertion of the lamp body, the clamping force of the claws must be overcome. The claws often apply pressure to the lamp body through their edges. The edges of the claws are relatively sharp. As is well known, under the same force, the smaller the force-bearing area, the greater the pressure, and the easier it is for the object to concentrate local stress and break. Therefore, when the pressure applied by the claws is too great, it is easy for the lamp body to break.

[0004] In view of the above, it is necessary to design a halogen lamp and lamp holder mating structure that can both prevent the halogen lamp and lamp holder from being crushed and broken during assembly and reduce the number of processing steps. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Utility Model Content

[0005] The objective of this invention is to provide a mating structure for a halogen lamp and a lamp holder, which helps to improve the lamp holder structure by eliminating the traditional claw fixing method, allowing the lamp body to be inserted and fixed along the lamp holder without being squeezed and broken. At the same time, it reduces the corresponding processing steps, which is conducive to reducing production costs and improving the product qualification rate.

[0006] The present invention achieves its objective by providing a halogen lamp and lamp holder assembly structure, comprising a lamp body, a lamp holder fixed to the lamp body, and an insulated pin fixed below the lamp holder. The lamp body is electrically connected to the lamp holder and the pin. The lamp holder has a pair of fixing bosses stamped along its length on one side near the upper end, extending into the lamp holder cavity. When the lamp body is inserted into the lamp holder from top to bottom, the fixing bosses press one side of the lamp body against it, causing the other side of the lamp body to abut against the side wall of the lamp holder opposite to the fixing bosses. Thus, the pair of fixing bosses presses and fixes the lamp body tightly within the lamp holder cavity.

[0007] In a specific embodiment of this utility model, the fixing boss has a platform formed in the middle of one side facing the lamp holder cavity.

[0008] In another specific embodiment of this utility model, one end of the lamp body is configured with a lamp body socket, the lamp body is inserted into the lamp holder through the lamp body socket, the lamp body is provided with a filament, the lamp body socket is provided with a pair of molybdenum plates, the two filament legs of the filament are respectively connected to the upper end of a molybdenum plate, the lower end of the molybdenum plate is respectively connected to a lamp foot, and the lower end of the lamp foot extends downward out of the lamp body.

[0009] In another specific embodiment of this utility model, the lamp holder has a hollow cuboid structure and is open from top to bottom.

[0010] In another specific embodiment of this utility model, the lamp holder has a fixed window on each of the front and rear sides near the top, and a welding window is provided on each of the two fixed windows below the lamp holder. A lamp holder welding foot is provided on the upper edge of each welding window.

[0011] In another specific embodiment of this utility model, an insulating sleeve is provided between the plug and the lamp holder, and a plug welding foot extends upward from the plug.

[0012] In a further specific embodiment of this utility model, the insulating sleeve is made of ceramic material.

[0013] In a further specific embodiment of this utility model, the two sides of the lamp body socket are formed with lamp body socket surfaces, and the two lamp body socket surfaces are respectively in close contact with the platform on the fixed boss and the side wall of the lamp holder opposite to the fixed boss.

[0014] The present invention has the following advantages due to the adoption of the above-mentioned structure: by abandoning the traditional claw guidance and fixing structure, and adopting a structure in which the stamped fixing boss squeezes the side of the lamp body and the fixing boss and the inner side wall of the lamp holder together clamp the lamp body, the lamp body will not be squeezed and broken when it is inserted into the lamp holder for fixing. At the same time, it reduces the corresponding processing steps, which is conducive to reducing production costs and improving product qualification rate. Attached Figure Description
