A chip fixing device

Abstract

The present invention provides a chip fixing device. The device comprises a circuit board, a Z-shaped torsional spring, a hook, a tube socket and a spacing cover. The tube socket and the hook are welded on the circuit board, the hook is located at the opposite angles of the tube socket, a chip is inserted on the tube socket, the spacing cover is arranged on the chip, the Z-shaped torsional spring is arranged on the spacing cover and is fixed through the two ends connected with the hook. The chip fixing device can eliminate the final motion and the friction between the chip pin and the tube socket hole caused in the vibration environment to solve the problem of the chip electrical contact reliability and avoid the product fault caused by vibration.

Description

technical field [0001] The invention belongs to the technical field of chip installation on engines, and in particular relates to a chip fixing device. Background technique [0002] Diesel engines are now electronically controlled, and the ECU is installed on the diesel engine, so the vibration is relatively large. There is a program chip in the ECU. In the process of use, especially in the development stage, there is a need for chip replacement. Therefore, in order to facilitate chip insertion, the tube socket is usually used after welding, and the chip is inserted on the tube socket. Under the action of vibration, the chip Micro-movement is easy to occur between the pin and the socket hole. Under the long-term micro-motion action, the contact part between the pin and the socket hole will be blackened by friction, and the electrical contact will be poor, which will lead to product failure. Contents of the invention [0003] In view of this, the present invention aims to ...
