What causes bad contact of wire crimping machine? For machines, poor contact has always been one of the main causes of failure, from small mobile phones, large computers, larger end-to-end sub-machines or aviation equipment. Since this problem is so important, we must pay attention to it. Let Fortune Sky wire crimping machine manufacturer analyze the bad contact problem of wire crimping machine today.
For a computer, the most common malfunction is the memory chip. For a wire crimping machine, the most common malfunction is the metal conductor inside the terminal. This part is the core part of the terminal. It transmits the voltage, current or signal from external wires or cables to the contacts corresponding to its matching connectors.
Because of its importance, the wire crimping machine is required to have stable and reliable contact and good conductivity. So what factors will cause poor contact of wire crimping machine contact structure?
In fact, this is a common factor, such as excessive processing size, unreasonable surface treatment technology such as heat treatment and plating, poor storage environment, poor and improper use and operation, etc., may make contact parts and coordination parts of automatic wire crimping machine poor contact.
Common fatal faults at terminals?
1. Poor contact
The metal conductor inside the terminal is the core part of the terminal. It transmits the voltage, current or signal from the external wire or cable to the contacts corresponding to its matching connector. Therefore, the contact parts must have excellent structure, stable and reliable contact retention and good conductivity. Due to the unreasonable structure design, wrong material selection, unstable die, excessive processing size, rough surface, unreasonable surface treatment process such as heat treatment and electroplating, improper assembly, poor storage and use environment and improper operation, all of these will cause poor contact at the contact and coordination parts of the contact parts.
2. Poor insulation
The function of insulator is to keep the contacts in the correct position, and to protect the contacts from the contacts and the shells from each other by insulating the conveyor. Therefore, insulators must have excellent electrical performance, conveyor protection mechanical performance and process forming performance. Especially with the wide use of high density and miniaturized terminals, the effective wall thickness of insulators becomes thinner and thinner. This puts forward more stringent requirements for insulation materials, precision of injection moulds and moulding technology. Due to the existence of metal redundancy, surface dust, flux and other contaminations on the surface or inside of insulators, the amalgamation of organic material precipitates and harmful gas adsorption film with surface water film to form ionic conductive channels, moisture absorption, long mold, aging of insulating materials and other reasons, will cause short circuit, leakage, breakdown, low insulation resistance and other bad insulation phenomena.
3. Poor fixation
Insulators not only play an insulating role, but also provide precise centering and protection for extended contacts. They also have the functions of installation, positioning and locking and fixing on equipment. Poor fixing, light impact on contact reliability, resulting in instantaneous power failure, the serious is product disintegration. Disintegration refers to the abnormal separation between plugs and sockets and between pins and sockets caused by unreliable structure due to material, design, process and other reasons, which will result in serious consequences of power transmission and signal control interruption of computer stripper in control system. Due to unreliable design, wrong material selection, improper selection of forming process, poor quality of heat treatment, die, assembly, welding and other processes, inadequate assembly will cause poor fixation.
In addition, due to coating peeling, corrosion, bruising, plastic shell flying edge, rupture, rough contact parts processing, deformation and other reasons caused by poor appearance, due to positioning and locking with poor size, poor consistency of processing quality, total separation force and other reasons caused by poor interchange, is also a common disease, frequently occurring. These kinds of faults can be found and eliminated in time in the process of inspection and use.
