Abstract
A securing fixture for the heat sink on a PC board, being made from a winding wire to get the advantage of low cost and convenient mounting and detachment. The structural body of the securing fixture is formed by extending a movable rod section downwardly and then bending it to form an insertion end which is wider on the upper portion and is narrower on the lower end thereof, and then by extending upwardly to form an action rod section of which the top is wound toward the lower end to form a spring section. The movable rod section and the action rod section are enveloped in the spring section, while the insertion end is at the bottom of the spring section. The insertion end is provided on the top thereof with a limiting portion with a width larger than the inner diameter of an engaging hole of the PC board. Thus the insertion end is engaged beneath the engaging hole of the PC board, while the spring section is stopped above the engaging hole of the heat sink, hence the heat sink is fixed on the PC board by means of the securing fixture.
