Comment juger si le matériau utilisé dans le connecteur à baïonnette est bon ou mauvais ?

In an increasingly competitive market, product quality is key, and customers or users are paying more and more attention to it. Each cardholder connector manufacturer has developed relative quality standards, but some manufacturers, in order to reduce costs, so the material on the big deal, such as using iron to replace copper as the conductor, resulting in the product quality has a great hidden danger. The key elements of the Card Holder Connector are made up of two parts, the first being the plastic insulator, the second the metal conductor. Today, Mo Kai Electronics on the two main parts, share how to distinguish the material used in the cardholder connector good or bad.

1, the insulating part of the card holder connector.
The cardholder connector insulator is to use our sense of smell and vision to identify, using the ignition of the plastic insulator to identify the strengths and weaknesses of the material. Some poor quality plastic materials in combustion, there will be a very strong pungent smell, and there is no draw of combustion fibres. On the contrary, the quality of the plastic material retained in the combustion, will not produce pungent smell, and the combustion fiber pulling a long time.

2, the conductive part of the card holder connector.
The conductive part of the card holder connector (we often say the terminal) must come from the use of high quality copper, to ensure that the card holder connector products have excellent transmission signal and conductive function. Because the surface of the terminal will have a layer of plating, we must use a blade to remove the plating surface, under a magnifying glass to see the colour of the bare material to distinguish the use of excellent material. If it is copper, we will see under the magnifying glass that the bare material appears red or yellow. If it is iron, it should appear black.
