Abstract

A radiator fixing apparatus is operable to fix a radiator on a circuit board. A groove is formed at the top of the radiator. The radiator fixing apparatus comprises a pressure rod accommodated in the groove, a fixing member and two positioning columns fixed on the circuit board. The two ends of the pressure rod are hung on the two positioning columns, and the fixing member penetrates through the pressure rod and then is fixed to the radiator. The radiator fixing apparatus is simple in structure and convenient for operation.

Description

Fixer for heat radiator

Technical field

The present invention relates to a kind of fixer for heat radiator.

Background technology

Radiator being fixed on circuit board usually through screw is electronic element radiating on circuit board, and this fixed form disassembly process is loaded down with trivial details, and during work consuming.

Summary of the invention

In view of more than, be necessary to provide a kind of fixer for heat radiator easy for installation.

A kind of fixer for heat radiator, for a radiator is fixed on a circuit board, the top of this radiator is provided with a groove, the reference column that this fixer for heat radiator comprises a depression bar being contained in groove, a fixture and two is fixed on circuit board, the two ends of this depression bar are hooked in this two reference column, and this fixture is fixed on radiator through after depression bar.

This fixer for heat radiator, structure is simple, easy to operate.

Main element symbol description

Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.

Embodiment

Referring to Fig. 1, the better embodiment of fixer for heat radiator 30 of the present invention, is that the electronic component 50 on circuit board 10 dispels the heat in order to a radiator 20 is fixed on a circuit board 10.

This fixer for heat radiator 30 comprises depression bar 31, fixture 33, two reference column 35 and an elastic component 37.In present embodiment, fixture 33 is a screw, and elastic component 37 is spring.

This radiator 20 comprises a square base 201.This base 201 is vertically provided with one first fin 207 and some the second fins 203 being positioned at these the first fin 207 both sides.The top of these the second fins 203 is recessed to form a groove 205 downwards along the diagonal of base 201.The height of this first fin 207 is less than the second fin 203, and the thickness of this first fin 207 is greater than the second fin 203.The middle part of the end face of this first fin 207 is provided with a fixing hole 208.

See also Fig. 2, this depression bar 31 comprises the force section 315 that kink 312 kink and two upwards bent from the middle part of depression bar 31 is connected to the both sides of kink 312.The center of this kink 312 is provided with a through hole 313.Each force section 315 is provided with a breach 317 away from one end of kink 312.This two breach 317 opening direction is contrary, and runs through the both sides of depression bar 31 respectively.

Refer to Fig. 1 and Fig. 5, each reference column 35 comprises the neck 355 of head 351, cylinder 353, connection header 351 and cylinder 353.Neck 355 compares head 351 and cylinder 353 is narrower.

Refer to Fig. 1 to Fig. 5, during installation, circuit board 10 is fixed in the bottom of this two reference column 35 and opposing electronic element 50 symmetric arrays.Radiator 20 is placed in the end face of this electronic component 50, depression bar 31 is positioned in this groove 205, the neck 355 of this two reference column 35 is made to be sticked in two breach 317 of depression bar 31, simultaneously between this force section 315 head 351 of being folded in reference column 35 and cylinder 353.By fixture 33 successively through the fixing hole 208 being fixed on this first fin 207 after the through hole 313 of depression bar 31 and elastic component 37.Elastic component 37 abuts kink 312 and the first fin 207.Namely this radiator 20 is fixed in circuit board 10.

This through hole 313 is positioned at the middle part of depression bar 31 and this fixing hole 208 is located at the middle part of the first fin 207, and when radiator 20 is fixed on circuit board 10, radiator 20, at radiator 20 center, can be stably fixed on circuit board 10 by stress point.
