Abstract

The utility model relates to a fluorescent lamp clamping plug structure. The plug structure comprises a poly carbonate (PC) cover and an aluminum chute which are clamped and connected tightly; clamping holes are formed in the aluminum chute; the plug structure also comprises a rotation plug upper cover, a rotation plug lower cover, a round head self tapping screw, and a spring sleeved on the round head self tapping screw; the rotation plug upper cover and the rotation plug lower cover are fixedly connected through the round head self tapping screw; the rotation plug lower cover is provided with a clamp; the clamp is coupled with the clamping holes rightly and is provided with a boss; the clamping holes comprise a small hole position and a large hole position; and the boss is coupled with the small hole position. The clamp on the plug is tightly clamped and connected with the hole positions, so that the fluorescent lamp clamping plug structure is stable in structure and convenient to assemble and disassemble, and improves production efficiency. The self tapping screw is arranged in the middle of the plug structure, so that the structural stability is improved further, and the fluorescent lamp clamping plug structure is attractive in appearance; and the aluminum chute contributes to the heat radiation of a printed circuit board (PCB), so that the service life of a lamp tube is prolonged.

Description

A kind of fluorescent lamp buckle plug structure

Technical field

The utility model relates to LED lighting apparatus field, is specifically related to a kind of LED fluorescent lamp buckle plug structure.

Background technology

At present; The lighting engineering of employing light emitting diode (LED) fluorescent tube has been widely used in commercial production, the life illumination; The LED lamp generally comprises body and the plug that is positioned at the body two ends, and contact pin is set on the plug, is used for cooperating with socket; The plug of existing LED fluorescent tube generally adopts integral structure, and the plug of this structure and the fixed form of body generally are divided into two kinds:

First kind is to adopt glue fixing, and this scheme workman's operation is easy to realize, but glue can be coated in appearance easily, influences the attractive in appearance of its appearance; The hardening time of glue is long, causes product efficiency low, and the contact pin on the plug adopts welding fixing, and the workman operating space is little; Be difficult for welding, can cause the fraction defective of product to raise, production efficiency is difficult to ensure, after the glue fixing; Plug is difficult to dismounting, and the product inconvenient maintenance is because the cause of glue; Cause louvre to reduce, the heat that power supply produces is difficult to distribute, and influences service life.

Second kind is to adopt screw to fix, and utilizes screw that plug is fixed on the two ends of body, though that this scheme is keeped in repair is more convenient; But the guest when mounted or guest when touching the fluorescent tube that is using, and screw is too near from the distance of high-pressure side, is easy to make screw and feeder ear generation high voltage arc; The person is damaged, and screw leaks the outward appearance that influence product in the outside, adopt when welding fixedly at contact pin; The operating space of flatiron is little, is difficult for welding, causes the fraction defective of product to improve; Production efficiency is low, causes the wasting of resources.

The utility model content

The problem that the utility model will solve provides a kind of LED fluorescent tube buckle plug structure, and in the middle of the plug inside configuration, self-tapping screw is set, and makes to accomplish not only on the structure that firmly its installing/dismounting all makes things convenient for.

For addressing the above problem; The utility model is realized through following scheme: a kind of fluorescent lamp buckle plug structure; This plug structure comprises PC cover, aluminium barrel and is fixedly installed on pcb board and the LED lamp on the aluminium barrel, and said PC cover links closely each other with the aluminium barrel and is connected, and said aluminium barrel is provided with block button hole; Said plug structure comprises rotation plug loam cake, rotation plug lower cover, round end self-tapping screw and is enclosed within the spring on the round end self-tapping screw; Said rotation plug loam cake is connected through the round end self-tapping screw with rotation plug lower cover to be fixed, and said rotation plug lower cover is provided with buckle, and said buckle and block button hole just are coupled.

One convexity is arranged on the said buckle.

Said block button hole is divided into aperture position and slotted hole position.

Said convexity and said aperture position are coupled.

The utility model adopts to link closely each other between buckle and the button hole position on the plug and is connected, and makes and accomplishes not only on the structure that firmly its installing/dismounting all makes things convenient for, and has improved production efficiency.Its self-tapping screw is arranged in the middle of the plug inside configuration, further improves structural stability, profile attractive in appearance more simultaneously, and the aluminium barrel helps the heat radiation of pcb board, the service life of prolonging lamp tube.

Below be to combine the specific embodiment and description of drawings that the utility model is done further description:
