Abstract
The utility model discloses a kind of LED lamp heat sink cover plate, comprise the cover board body of circular plate, cover board body is provided with screw hole, described cover board body edge is provided with flange upwards, and described screw hole is provided with turned welt.The basis of the circular hole screw hole of the utility model before improvement stretches to screw hole, in the turned welt structure that the upper formation one of radiator cover plate is protruding, be convenient to effective tooth number that can increase screw thread when follow-up assembling aluminium base, strengthen the fixation to screw.
Description
Technical field
The utility model relates to LED, particularly relates to LED lamp heat sink cover plate.
Background technology
Along with LED radiator cost constantly decline, the continuous lifting of matching requirements, the requirement of radiator cover plate is improved constantly, there is the phenomenon of cover plate median rise in the cover plate before improvement, causes aluminium base and cover plate contact area to reduce, can not well dispel the heat when assembling; Circular hole screw hole before improvement does not have to be easy to when connector occur when aluminium base assembles loosening in radiator casing inside, once occur that the whole radiator cover plate of situation of sliding tooth has just been scrapped, adds follow-up cost.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of LED lamp heat sink cover plate, avoids the sliding tooth of screw hole outlet.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LED lamp heat sink cover plate, comprises the cover board body of circular plate, cover board body is provided with screw hole, described cover board body edge is provided with flange upwards, and described screw hole is provided with turned welt.
Preferably, described turned welt protrudes above cover plate.
Preferably, described turned welt protrudes below cover plate.
Preferably, described turned welt passes through drawing and forming.
Preferably, the height of described turned welt is 1mm ~ 5mm.
The basis of the circular hole screw hole of the utility model before improvement stretches to screw hole, in the turned welt structure that the upper formation one of radiator cover plate is protruding, be convenient to effective tooth number that can increase screw thread when follow-up assembling aluminium base, strengthen the fixation to screw, also play and do not allow effect easy to slip teeth.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of LED radiating subassembly;
Fig. 2 is the top view of radiator cover plate;
Fig. 3 is embodiment 1 cover plate A-A sectional view;
Fig. 4 is embodiment 2 cover plate A-A sectional view;
Fig. 5 is embodiment 3 cover plate A-A sectional view;
Fig. 6 is embodiment 4 cover plate A-A sectional view.
Detailed description of the invention
Embodiment 1 of the present utility model, as shown in Figure 1 to Figure 3, a kind of LED radiating subassembly, the connector 2 comprising radiator casing 3 and be located in radiator casing 3 and radiator cover plate 1, described radiator casing 3 is for moulding alclad structure, described radiator casing inner bottom surface is provided with around inner bottom surface centre bore and supports anchor ring 31, connector bottom support is on support anchor ring, radiator cover plate 1 gland is on connector 2, this radiator cover plate 1 comprises the cover board body 10 of circular plate, cover board body is provided with screw hole 101, the corresponding screw hole of described connector 2 is provided with circular hole 21, described cover board body edge is provided with flange 11 upwards, described radiator casing inwall is provided with inner circle section 33 on the upside of female cone section 32, described flange coordinates with radiator casing inner circle section contact internal walls, described flange and cover board body connecting part are provided with chamfering.
In the present embodiment, as shown in Figure 3, flange 11 is annular.Cover plate before improvement is few with the contact area of moulding alclad when assembling, and heat dispersion is poor, can only do the LED that wattage is lower.This radiator cover plate only turns over a limit, reduces the operation of punching press, reduces cost.Increase the contact area (approximately increasing by the contact area of 7.62%) of lid surface and aluminium base, aluminium base can better be dispelled the heat; Add large cover and the contact area of moulding alclad, high-power LED can be made.
In embodiment 2, as shown in Figure 4, described screw hole is provided with turned welt 102, and described turned welt protrudes above cover plate.Before improving, aluminium base is when screwing, and does not have locating hole, needs manual-alignment, time-consuming, effort, also may causing hole misalignment, and screw trains off.It is circular hole screw hole before improvement basis on reverse-drawing is carried out to hole, a protruding shape is formed at the reverse side of radiator cover plate, be convenient to effective tooth number that can increase screw thread when follow-up assembling aluminium base, strengthen the fixation to screw, also play and do not allow effect easy to slip teeth.
In addition, in the present embodiment, described flange 11 is provided with reinforcement structure, and described reinforcement structure is the concave inward structure 111 that chamfer site caves in inside cover board body.Described concave inward structure and radiator cover plate integrated punching shaping, define the structure of reinforcement.
In embodiment 3, as shown in Figure 5, described turned welt protrudes below cover plate.It is circular hole screw hole before improvement basis on hole is stretched, directly play the effect of fixing aluminium base when aluminium base is screwed, reduce employee's unnecessary time to hole, save time, laborsaving.
Embodiment 4, as shown in Figure 6, described flange is U-shaped bending structure, can increase the area of dissipation of cover plate.
Claims (5)
