Abstract

The utility model discloses a PCB (Printed Circuit Board) fixing device of an LED (Light Emitting Diode) fluorescent tube. A PCB is installed on a radiating partition of an aluminum tube of the tube; the fixing device comprises plastic buckles, a plurality of small holes which mutually correspond are respectively formed in the PCB and the radiating partition of the aluminum tube of the tube, and clamping grooves of the plastic buckles are formed in the small holes; and each plastic buckle comprises a big end and a small end, wherein each big end is used for pressing, each small end is used for passing through the small holes, and each big end and each small end are mutually connected to form an annular clamping groove. According to the PCB fixing device, the plastic buckles are adopted to fixedly connect the PCB with the radiating partition of the aluminum tube of the tube, and connection can be realized only by pressing by hand; the PCB fixing device has the advantages of simplicity and rapidity in operation, high efficiency, convenience in disassembly and assembly, safety and reliability; and the problem of influence on production because the smaller clamping grooves of the traditional fixing device cannot be used for assembly and the problem of potential safety hazards due to inadequate creepage distance caused by the fact that self-tapping screws are adopted to fix are solved.

Description

A kind of pcb board fixture of LED fluorescent tube

Technical field

The utility model relates to a kind of assembling device of LED fluorescent tube, relates in particular to a kind of pcb board fixture of LED fluorescent tube.

Background technology

The LED fluorescent lamp is the electronic product that the skill achievement in fields such as applied power electronics, optics, calorifics, semiconductor material science, Metal Material Science is developed out, has the characteristics of long-life, high light efficiency, high-color rendering, environmental protection and energy saving.The PCB(of existing LED fluorescent tube is aluminium base) fixing aluminium section bar draw-in grooves chuckings that adopt between the heat radiation dividing plate of the aluminum pipe of plate and fluorescent tube are fixing more, and how axial direction is fixed with pushing the two ends draw-in groove, or attack screw with self tapping and fix.All there is defective in above-mentioned two kinds of fixed forms: the aluminium section bar draw-in groove often diminishes because draw-in groove appears in the mould problem, can not assemble influence and produce; Adopt tapping screw to fix and then can have potential safety hazard because creep age distance is not enough.

The utility model content

The purpose of this utility model just is to provide in order to address the above problem a kind of pcb board fixture of simple and feasible and safe and reliable LED fluorescent tube.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The pcb board fixture of LED fluorescent tube described in the utility model, described pcb board is installed on the heat radiation dividing plate of aluminum pipe of described fluorescent tube, described fixture comprises plastic buckle, be respectively equipped with the aperture of a plurality of mutual correspondences on the heat radiation dividing plate of the aluminum pipe of described pcb board and described fluorescent tube, the draw-in groove of described plastic buckle places in the described aperture.Adopt the heat radiation dividing plate of the aluminum pipe of the fixedly connected pcb board of plastic buckle and fluorescent tube, only with hand is pressed and can be realized, and is very convenient.

Particularly, described plastic buckle comprises be used to the big termination of pressing with for the small end head that passes described aperture, interconnects and form annular slot between described big termination and the described small end head.

Further, the outer end of described small end head is tapered, and the middle part of described small end head is provided with opening at axial direction.

Be respectively equipped with three apertures on the heat radiation dividing plate of the aluminum pipe of described pcb board and described fluorescent tube.

The beneficial effects of the utility model are:

The utility model adopts the heat radiation dividing plate of the aluminum pipe of the fixedly connected pcb board of plastic buckle and fluorescent tube, only with hand is pressed and can be realized, simple to operate, quick, efficient is high, dismantle easy to assembly and safe and reliable, and solved that conventional fixation means exists can not assemble the problem that influence produces and adopt the fixing problem that can have potential safety hazard because of creep age distance inadequately of tapping screw because draw-in groove diminishes.

Description of drawings

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is the perspective view of plastic buckle described in the utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As depicted in figs. 1 and 2, pcb board 3 described in the utility model is installed on the heat radiation dividing plate 6 of aluminum pipe 5 of fluorescent tube, the pcb board fixture of LED fluorescent tube described in the utility model comprises plastic buckle 7, plastic buckle 7 comprises be used to the big termination 8 of pressing with for the small end head 11 that passes aperture, interconnect and around joint pin 10, form annular slot 9 between big termination 8 and the small end head 11 by joint pin 10, the outer end of small end head 11 is tapered, and the middle part of the middle part of small end head 11 and joint pin 10 is provided with opening 12 at axial direction; Be respectively equipped with three aperture (not shown)s of correspondence mutually on the heat radiation dividing plate 6 of the aluminum pipe 5 of pcb board 3 and fluorescent tube, the annular slot 9 of plastic buckle 7 places in the described aperture.

Also show lamp holder 1, PC cover 2 and led light source 4 among Fig. 1.

In conjunction with Fig. 1, Fig. 2 and Fig. 3, during installation, pcb board 3 is placed on the heat radiation dividing plate 6 of aluminum pipe 5, make its position, hole alignment, direct small end head 11 patchhole positions with plastic buckle 7, because opening 12 makes small end head 11 and joint pin 10 have elasticity, and the outer end of small end head 11 is tapered, so, can easily plastic buckle 7 be pressed into aperture and pass aperture, after passing, utilize the elastic reset of small end head 11 and joint pin 10, this moment, the annular slot 9 of plastic buckle 7 placed in the aperture, and the outside of pcb board 3 and heat radiation dividing plate 6 closely contacts with the inboard of small end head 11 with big termination 8 respectively, realizes fixed installation.
