During the use of the connector terminals of the connector, the surface of the coating may peel, corrode, collide, fray, break, and parts in close contact with the workpiece may become rough or deformed, resulting in poor appearance.

1. Bad insulation of connector terminals

The function of the connector terminal insulator is to hold the contacts in the correct position and to insulate them from the contacts and from the housing.Therefore, insulators must have excellent electrical properties, mechanical properties and processing and molding properties.In particular, with the widespread use of high density and miniaturized terminals, the effective wall thickness of insulators is getting thinner.This puts forward more strict requirements for insulating materials, injection mold precision and molding process.

2. The connector terminal is not properly fixed

The connector terminals need to be fixed in a specific position to achieve a stable connection.If the installation is not ideal or the life cycle of product insertion and removal is insufficient, the immobility is poor. Slight contact will affect contact, resulting in instantaneous power failure and severe product disintegration.Disintegration refers to the abnormal separation between the plug and socket due to the unreliability of the structure due to the material, design, process and other reasons. The power transmission of the control system is caused by the disconnection of the power supply.Terminal.Serious consequences of signal control interruption.Due to unreliable design, incorrect material selection, improper molding process selection, poor quality of heat treatment, mold, assembly, welding, etc.,

3. Bad connector terminal contact

The metal conductor inside the connector terminal is the core part of the terminal, which will transmit power, signal and so on to the other parts in contact with it. Therefore, the metal conductor inside the terminal must have good conductive performance.Contacts at connector terminals may be defective if contacts are not properly designed, materials are selected incorrectly, dimensions are not standard, or plating is not handled properly.
