Wiring optimization method based on high-precision electro-hydraulic converter

Abstract

The invention discloses a wiring optimization method based on a high-precision electro-hydraulic converter, and belongs to the technical field of welding processes. According to the invention, the wiring optimization method comprises the steps of cutting out a wire, welding the wire with a right-angle insertion spring, welding the right-angle insertion spring with an electro-hydraulic converter binding post, and detecting the welding firmness. The wiring optimization method based on the high-precision electro-hydraulic converter is used; compared with the existing laser welding or spot weldingtechnology; according to the technical scheme, a right-angle insertion spring and seepage welding combined method is adopted; the wire can be connected to the electro-hydraulic converter more firmly,the problems of welding spot falling and wire strand breaking caused by vibration during work of the electro-hydraulic converter are avoided, and the wiring optimization method has the advantages ofbeing firm, reliable, practical, easy and convenient to install and low in cost and is suitable for field maintenance of the high-precision electro-hydraulic converter in the production line.

Description

technical field [0001] The invention relates to the technical field of electric wire connection technology, in particular to a connection method between a terminal head and a wire of a high-precision electro-hydraulic converter. Background technique [0002] When the existing electrical wires are electrically connected, soldering or laser welding is usually used. The electro-hydraulic converter is an important device that converts electrical signals into hydraulic signals to drive hydraulic actuators. It is often used in generator sets. The electro-hydraulic converter consists of two parts: one part is the electric-displacement conversion part; the other part is the hydraulic pressure amplification part. The electrical-displacement conversion part is to place a group of coils in the air gap of the magnetic circuit composed of permanent magnet steel, iron core, etc. The coil is balanced in the middle position by a spring. There are usually three coils in this group, two of...

AI Technical Summary

Problems solved by technology

[0004] 1) The connection method of wires and terminal posts is crossed, and the installation is not firm enough, because the wires do not have enough support due to the soldering method of crosses, and can only be fixed by welding points, so that the wires of the electro-hydraulic converter will be damaged. At the same time, it receives the up and down traction force, the left and right stretching force and the vibration frequency signal of the equipment. After long-term work, the connection will not be firm or even fall off;

[0005] 2) Spot tin soldering is easy to desolder, because spot tin soldering has high requirements for the current installation conditions and installation process, which will make the solder on the contact surface unable to be completely covered, so that the process cannot be effectively guaranteed. Deviation, then in the state of long-term low-frequency vibration, such a welding method will lead to desoldering, which will make the equipment unable to be effectively controlled;

[0006] 3) The method of laser welding has high environmental requirements and high cost. Laser welding needs to be processed by special equipment in the factory before it can be implemented. It is not suitable for follow-up maintenance at the use site of the electro-hydraulic converter;

[0007] 4) In the way of direct soldering or laser welding, the electrical wires are often not effectively protected, and are prone to aging and wear; due to the precision requirements of the electro-hydraulic converter, the diameter of the wires is generally ≤0.5mm, and ordinary wire lugs are used. The method makes the connection of the wires unable to be effectively protected against oil and vibration, and long-term operation will cause wire wear and strand breakage
