Problems solved by technology
[0004] 1. Due to the small size of the lead wires of the micro resistors, the positive and negative lead wires are relatively thin, and the connection position is fixed by soldering. During the vibration operation of the machine, the lead wire connection position will be broken due to the vibration, which will affect the operation of the control circuit. ;
[0005] 2. Due to the large power of the circuit board of the large computer, the heat generated by the current is high, and it is easy to cause melting at the soldering position, which will cause the micro-resistor and the circuit board to fall off, causing circuit failure
[0006] To this end, a micro-resistor installation structure on the surface of the computer host controller is provided to solve the vibration problem of the micro-resistor and the solder melting problem

The invention relates to the technical field of resistance installation of computer circuit boards, in particular to a micro-resistor installation structure on the surface of a computer host controller, including a circuit board. The circuit board is composed of a main substrate, an upper insulating layer and a soldering layer. The upper end is provided with a pair of left and right symmetrical jacks, the lower end surface of the installation frame is provided with a pair of mutually symmetrical conductive brackets, and the inner cavity of the installation frame is provided with an installation inner cavity. The large mounting frame and thick conductive bracket realize the electrical connection with the circuit board, thereby avoiding the breakage of the thin lead wires, greatly improving the stability of the installation, and reducing the influence of heat and vibration on the connection position; The upper connection position is equipped with folded buffer leads and rubber buffer rods to realize the buffering of the installation position of the micro-resistor, reduce the impact of vibration on the circuit connection, and improve the shock resistance and stability of the connection of the circuit pair.
Description
technical field [0001] The invention relates to the technical field of resistance installation of computer circuit boards, in particular to a micro-resistor installation structure on the surface of a computer host controller. Background technique [0002] More micro-resistors need to be installed on the surface circuit board of the computer controller, and traditional micro-resistors are usually provided with two mutually symmetrical lead wires to realize soldering connection with the circuit board. [0003] However, for industrial or large-scale computer controller circuit boards, there are many defects in micro-resistors: [0004] 1. Due to the small size of the lead wires of the micro resistors, the positive and negative lead wires are relatively thin, and the connection position is fixed by soldering. During the vibration operation of the machine, the lead wire connection position will be broken due to the vibration, which will affect the operation of the control circuit...
