Abstract

The invention relates to a radiation device assembly used for radiating heating electronic elements on a circuit board, which comprises a radiator and a fastener. The radiator comprises a bottom plate and a plurality of radiation fins arranged on the bottom plate. A channel is formed between every two adjacent radiation fins. The fastener comprises a body contained in the channel and two fastening hooks connected with the two ends of the body and buckled with the circuit board. The body of the fastener comprises a pair of abutting parts abutting against the bottom plate. The tail end of each abutting part extends to form a fastening arm. The tail end of each fastening arm is bent to extend to form an operation part connected with the fastening hooks. The operation part is bent to form an operation face on which outer force acts. Each operation part is bent toward the direction away from the abutting part and is provided with an opening facing the abutting part. The abutting part is in a linear shape and the operation face of the operation part is used for receiving the application of an external force. Thus, the fastening arms are rotated with the abutting parts as the rotating shafts thereof, so as to be connected with or separated from the circuit board. Since the fastener of the radiation device assembly is provided with operation parts and operation faces on which the outer force acts, the touch area between the outer force and the fastener is increased. The radiation device assembly has the advantages of convenient operation, time saving and labor saving.

Fig. 2 is the three-dimensional combination figure of combination of radiating device among Fig. 1, and wherein the part radiating fin removes.
Fig. 3 is the end view of combination of radiating device among Fig. 1.
Fig. 4 is the structural representation that combination of radiating device is installed in a circuit board among Fig. 1.
Embodiment
Fig. 1 to Fig. 4 discloses the combination of radiating device in one embodiment of the present invention, it is used for distributing the heat of the electronic component (not shown) generation that is installed on the circuit board 100, and this combination of radiating device comprises a radiator 10 and is used for radiator 10 is fixed to a fastener 20 of fitting with electronic component on the circuit board 100.
Radiator 10 is by one-body molded making such as high thermal conductivity material such as copper, aluminium or its alloys.Radiator 10 comprises roughly rectangular base plate 12 and some radiating fins 14 of extending vertically upward from base plate 12.These radiating fin 14 spaces and a pair of long side that is parallel to base plate 12 form the runner (indicating) that air feed stream passes through between the per two adjacent radiating fins 14.Form the groove 18 of a vertical bar shaped between centre two adjacent radiating fin 14a, the 14b of base plate 12.Groove 18 is used for accommodating fastener 20.Two adjacent radiating fin 14a, 14b extend a pair of protuberance 16a, 16b relatively, the base portion thickness of radiating fin 14a, 14b is large than other radiating fins 14 at this moment, its purpose is to dwindle the distance between this two radiating fin 14a, the 14b, thereby form the groove 18 corresponding with the width of fastener 20, moreover, also strengthen simultaneously the intensity of this two radiating fin 14a, 14b, thereby can bear the fastening power that produces when fastener 20 fastens radiator 10.
Fastener 20 is the line style fastener, is formed by elastic metal wire one bending, and it comprises a body (figure is mark), two pressure sections 22 that this body comprises a support portion 21 and 21 both ends horizontal is extended from the support portion.Two pressure sections, 22 outer ends are extended two extensions, 23, two extensions, 23 outer ends and are continued to tilt to extend upward two button arms 24.An operating portion 25 is extended in each button arm 24 bending, and the end of each operating portion 25 forms a clasp 26.
Support portion 21, pressure section 22 be shape linearly all, and its total length just is the length (please refer to the drawing 2) of the base plate 12 of radiator 10.Support portion 21, pressure section 22 can just be contained in the groove 18 of base plate 12 of radiator 10.Two pressure sections 22 are formed by the downward horizontal-extending in the two ends of support portion 22 respectively.And this two pressure section 22 21 is and is symmetrical arranged and is parallel to support portion 21 along the support portion.The end of two pressure sections 22 vertically extends to form two extensions 23 more up, and this two extension 23 is perpendicular to two pressure sections 22, and this two extension 23 is along pressure section 22 and is symmetrical arranged.Extension 23 has certain height, thus for operating portion 25 provides certain operating space, when avoiding operating portion 25 operation and radiator 10 interfere.The thickness of the base plate 12 of the vertical height of extension 23 and radiator 10 about equally.This two extension 23 just places the both sides of the base plate 12 of radiator 10, thereby makes two button arms 24 be positioned over the both sides of the base plate 12 of radiator 10, and provides certain operating space for operating portion 25.
Two button arms 24 are inclined upwardly to extend by the end of extension 23 respectively and form.Two button arms 24 all tilt with extension 23, but two button arms 24 oppositely arrange with respect to support portion 21.The ends of two button arms 24 bend respectively and extend to form operating portion 25, operating portion 25 by after the 24 terminal upwards bendings of button arm again back bending form, i.e. operating portion 25 bendings surround an operating surface, when External Force Acting during at fastener 20, can provide a larger contact-making surface.Each operating portion 25 roughly takes the shape of the letter U, and operating portion 25 bending extends to form an opening 250, and its opening 21 is offered towards the support portion.The clasps 26 that the ends of two button arms 24 form are extended by the 24 terminal upwards bendings of button arm and form, clasp 26 be used for this circuit board 100 on clasp 120 fasten and radiator 10 be fixed to this circuit board 100.
Utilizing fastener 20 with radiator 10 fixedly the time, support portion 21, the pressure section 22 of fastener 20 passed two radiating fin 14a, the 14b of radiator 10 and place in the groove 18 of base plate 12 of radiator 10, the clasp 120 that respectively clasp 26 is fastened on the circuit board 100 again gets final product.Because pressure section 22 shape linearly, so that fastener 20 can do to rotate on a large scale relative to radiator 10 in that groove 18 is interior, thereby make things convenient for the clasp 120 on clasp 26 and the circuit board 100 to be interlocked.When external force acts directly on the operating portion 25 of fastener 20, because the bending structure of operating portion 25 design, the operating surface that operating portion 25 provides for external force, increase the contact area between external force and the operating portion 25, namely need not too large external force and just can utilize fastener 20 that radiator 10 is fixed on the circuit board 100, easy to operate, time saving and energy saving.
