ZH1.5 White PA66 LCP Connector Wafer SMT H6.0 Lying Paste
Connector pins use plastic raw materials: Nylon, polyester, Nylon, high temperature - PBT, polyester - PCT, PPS, LCP, and so on, different liquidity in the process of molding, plastic material flow length, shrinkage, water imbibition, linear expansion coefficient is different, in plastic mold development has a lot to do with the materials used is accurate calculation.
The needle seat is generally said to be the line to the board connector, because only the line to the board connector said the needle seat, the line to the line connector does not have the needle seat, the board to the board connector is about the row of pins and female, etc. Of course, there are some exceptions, such as the SAN90/180 degree (also known as JC20-90 degree) connector, is a wire-to-board connector, but there is no pin holder.
The material of the needle holder is generally phosphor bronze or alloy and then the surface is tinned or copper plated with gold, according to the needs of the product. The drawing force of the needle seat is also very important. Generally, in important products, the drawing force will be considered, as well as the number of inserting and pulling so that the quality of the needle seat will be tested. The needle seat of the wire to the plate connector is the core of the core.
Connector is a component that our electronic engineers and technicians often contact. Its function is very simple: in the circuit is blocked or isolated between the circuit, set up a communication bridge, so that the current flow, so that the circuit to achieve the desired function. Connectors are indispensable parts of electronic equipment. Follow the path of current flow and you will always find one or more connectors. Connector forms and structures are ever-changing, with the application object, frequency, power, application environment and so on, there are different forms of connector. For example, the connector used to light the lights on the court is very different from the connector used to light the hard drive or the connector used to light the rocket. But no matter what kind of connector, it is necessary to ensure that the current flows smoothly and continuously and reliably. In general terms, the connector is not only connected to the current, in the rapid development of optoelectronic technology today, the carrier of signal transmission in optical fiber system is light, glass and plastic instead of ordinary circuit wire, but optical signal path also use connectors, their role is the same as the circuit connector.
