Abstract
The utility model discloses a power device fixing apparatus which is a spring pressing plate. A power device is fixed at the inner side of the side wall of a radiator by the spring pressing plate, a part, which presses against the power device, of the spring pressing plate is U-shaped, and the outer side of the spring pressing plate is provided with round concave spots and clings to the outer side of the radiator. The power device fixing apparatus is simple and reasonable in structure, the power device is fixed through the spring pressing plate, the part, which presses against the power device, of the spring pressing plate is U-shaped, the outer side of the spring pressing plate is provided with the round concave spots, and contact between the U-shaped pressing plate and the power device and contact between the round concave spots and the radiator are both improved into point contact from surface contact, thereby greatly increasing the fixing force, and improving the assembling efficiency of the power device. The assembling efficiency can be more than double the traditional assembling efficiency, and the problem that the power device is broken down easily by residual stress generated by traditional screw locking is solved.
Description
Technical field
The utility model relates to the mounting technique of power device, particularly a kind of fixture of power device.
Background technology
In the installation component of existing power tube, according to different installation methods two kinds of corresponding installation components are arranged: first kind is that the installing hole that directly passes metal-oxide-semiconductor (field effect transistor) with screw is fixed on the radiator, but to have rotation stress residual for the power tube pin after fix, and the power tube that stress is big is breakdown easily; Second kind is to press power tube with " 7 " font assembly, passes radiator shell with screw then and is locked on the 7 font assemblies.Above technology all needs with screw locking, complex process, and the production efficiency of assembling is low, and first method also may cause power tube breakdown.Present known fixed mode, the MOA pipe radiator structure (Chinese patent publication number CN202526681U) that is used for electrodeless lamp electronic ballast, wherein describe and use silicon steel clip fixed clamp fixedly metal-oxide-semiconductor and shell, portion and warping part and metal-oxide-semiconductor are plane contact but clip arches upward, its stationarity is limited, easily causes to come off.
The utility model content
The purpose of this utility model provides a kind of fixture of the power device that addresses the above problem.
The purpose of this utility model is realized by following technical scheme: a kind of fixture of power device, it is spring pressuring plate, spring pressuring plate is fixed on power device the inside sidewalls of radiator, press to the power device place and be U-shaped shape, the spring pressuring plate arranged outside has circular concave point, the held against heat sink outside.
Described power device adopts dielectric film to seal, and power device and radiator and spring pressuring plate are isolated, and reaches the insulation purpose.
Described U-shaped compressing tablet is for be interrupted arranging, economical with materials and can increase bed knife.
The utility model is simple and reasonable, it is by spring pressuring plate constant power device, press to the power device place and be U-shaped shape, the spring pressuring plate arranged outside has circular concave point, U-shaped compressing tablet is improved to a some contact with contacting all of radiator from the face contact with power device and circular concave point, has increased bed knife greatly, improves the efficiency of assembling of power device, efficiency of assembling can reach tradition more than 2 times, and solves the stress-retained power device breakdown problem easily of leading of traditional locks screw generation.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred forms;
Fig. 2 is the structural representation of the utility model spring pressuring plate.
Embodiment
Now further specify the execution mode of the best of this practicality in conjunction with Figure of description:
As Fig. 1, shown in Figure 2, a kind of fixture of power device, it is spring pressuring plate 5, and spring pressuring plate 5 is fixed on the inside sidewalls of radiator 1 with power device, presses to the power device place and is U-shaped shape 6, spring pressuring plate 5 arranged outside have circular concave point 7, the held against heat sink outside.Wherein printed circuit board (PCB) 2 is located in the radiator 1, and power device stitch 4 is welded on the printed circuit board (PCB) 2.
Described power device 3 adopts dielectric film 8 to seal, and power device 3 and radiator 1 and spring pressuring plate 5 are isolated, and reaches the insulation purpose.
Described U-shaped compressing tablet is for be interrupted arranging, economical with materials and can increase bed knife.
Claims (3)
1. the fixture of a power device is characterized in that, this fixture is spring pressuring plate, this spring pressuring plate is fixed on power device the inside sidewalls of radiator, press to the power device place and be U-shaped shape, the spring pressuring plate arranged outside has circular concave point, the held against heat sink outside.
