Position is placed on chip, and the Z-shaped torsional spring is placed on limited cover, and the both ends by being connected with hook are fixed.
Further, the limited cover shape is consistent with chip shape, and bottom surrounding is to having several limit convex edges,
Center offers observation window, and top two sides are equipped with torsional spring limiting slot.
Further, the limit convex of the limited cover bottom matches along the rectangular surfaces size and chip shape surrounded.
Further, each torsional spring limiting slot is recessed by two arc convex and the arc between arc convex
Slot is constituted.
Further, the Z-shaped torsional spring is spring steel wire, and shape is in " Z " font, and the two-arm of the Z-shaped torsional spring upwarps, and
Both ends are equipped with the straight hook upwarped.
Further, the long hook end of the hook is welded on wiring board, and the diameter of the hook of the hook is greater than Z-shaped torsional spring
Gauge of wire.
Further, the tube socket bottom is equipped with pin corresponding with chip pin position, and top is communicated with pin
Bore, the bore is interior to be equipped with reed.
Compared with the existing technology, chip fixture apparatus of the present invention has the advantage that
Chip fixture apparatus of the present invention passes through limited cover, Z-shaped torsional spring and extension on the basis of traditional plug connection
The setting of hook eliminates fine motion, the friction between chip pin and tube socket bore, solves chip and electrically connect under vibration
Integrity problem is touched, product failure caused by avoiding because of vibration.
