Abstract
The invention relates to an improved IC fixed spring plate of an automobile power amplifier. The improved IC fixed spring plate of automobile power amplifier is formed by an elastic sheet metal. The elastic sheet metal is bent in an S shape; pins are respectively arranged at two ends of the elastic sheet metal; all the pins are formed by bending of two ends of the elastic sheet metal; and bending directions of the two pins is opposite to the bending direction of the elastic sheet metal. The width of one pin is greater than the width of the other pin. A pair of IC fixed spring plate fixed grooves are arranged at inner walls of a radiator; and the IC fixed spring plate fixed grooves include two channel sections. And the pins at the two ends of the elastic sheet metal are respectively inserted into the channel sections. When the elastic sheet metal is deformed elastically, an outboard of an arc bending portion of the elastic sheet metal enables an IC integrated circuit chip to be pressed at the inner wall of the radiator. According to the invention, an elastic sheet metal is cooperated with a radiator with two channel sections during an extrusion process as well as the elastic sheet metal is deformed elastically, so that fixing and heat radiation are realized; it is unnecessary to independently process IC fixed spring plate fixed grooves on the radiator; and the manufacturing cost of the radiator can be reduced to the greatest degree.
Description
Technical field
The present invention relates to electricity field, relate in particular to the power amplifier that is used for hoot device, particularly a kind of improved vehicle power amplifier IC fixation spring tab.
Background technology
The IC chip that uses in the power of vehicle amplifier (IC) element, its heat loss power is bigger, in order to guarantee IC element operate as normal, needs radiator that it is dispelled the heat.For the heat that makes IC can fully be delivered on the radiator, available technology adopting IC fixation spring tab is fixed IC, makes IC ability held against heat sink, guarantees the heat radiator that is delivered to as much as possible on the IC.For fixing IC fixation spring tab, on radiator, process screw hole, hold-down screw is fixed to the IC fixation spring tab on the radiator through screw hole.The binding face of IC and radiator is perpendicular to radiator extrusion molding cross section, need be after the radiator extrusion molding each heat sink part be processed screw fixed hole separately with fixing IC fixation spring tab, increased the radiator manufacturing cost.
Summary of the invention
The object of the present invention is to provide a kind of improved vehicle power amplifier IC fixation spring tab, described this improved vehicle power amplifier IC fixation spring tab will solve the technical problem that radiator needs independent fixed processing hole that the IC fixation spring tab is installed in the prior art.
This improved vehicle power amplifier IC fixation spring tab of the present invention is made up of an elastic sheet metal; Wherein, The S-shaped bending of described elastic sheet metal; The two ends of elastic sheet metal are respectively arranged with pin, and any described pin constitutes in two ends bendings by elastic sheet metal, and the overbending direction of two pins and elastic sheet metal is opposite.
Further, the width of the pin of an end of elastic sheet metal is greater than the width of the pin of the other end.
Further, the width of the pin of the other end of elastic sheet metal equals the width of elastic sheet metal.
Operation principle of the present invention is: it extrudes the inwall upper edge of radiator direction and is provided with a pair of IC fixation spring tab holddown groove; IC fixation spring tab holddown groove is made up of two draw-in grooves; The pin at elastic sheet metal two ends inserts draw-in groove respectively; Elastic sheet metal generation strain, the outside of an arc-shaped bend portion of elastic sheet metal is pressed in the IC IC chip on the inwall of radiator.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes the elastic sheet metal of S-shaped bending to constitute the IC fixation spring tab; The radiator that elastic sheet metal has two draw-in grooves when extruding cooperates; Strain takes place, and the outside of an arc-shaped bend portion of elastic sheet metal can be pressed in the IC IC chip on the inwall of radiator, realizes fixing and heat radiation; Need not to process separately IC fixation spring tab holddown groove on the radiator, farthest reduce the manufacturing cost of radiator.

Embodiment:
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; A kind of improved vehicle power amplifier IC fixation spring tab of the present invention is made up of an elastic sheet metal 1, wherein; Described elastic sheet metal 1 S-shaped bending; The two ends of elastic sheet metal 1 are respectively arranged with pin 2 and pin 3, and bending constitutes pin 2 at two ends by elastic sheet metal 1 with pin 3, and pin 2 is opposite with the overbending direction of elastic sheet metal 1 with pin 3.
Further, the width of the pin 2 of an end of elastic sheet metal 1 is greater than the width of the pin 3 of the other end.
Further, the width of the pin 3 of the other end of elastic sheet metal 1 equals the width of elastic sheet metal 1.
The course of work of present embodiment is: it extrudes the inwall upper edge of radiator 4 direction and is provided with a pair of IC fixation spring tab holddown groove; IC fixation spring tab holddown groove is made up of two draw-in grooves 5; The pin at elastic sheet metal 1 two ends inserts draw-in groove 5 respectively; Strain takes place in elastic sheet metal 1, and the outside 6 of an arc-shaped bend portion of elastic sheet metal 1 is pressed in IC IC chip 7 on the inwall of radiator 4.
