What should be noted when selecting the pin header connector Pin header connector processing requirements of the material

What should be noted when selecting the needle row mother connector? Many customers to the editorial response in the selection of the row of pins and rows of female connectors do not know what to pay attention to, then we have sorted out the following seven points of attention: 1, the selection of the row of pins and rows of female connectors from a practical point of view, according to the use of the selection. Such as for radio, recorders, television external input, playback output, etc. can choose a small two, three heart row pin row mother connector. Such as for audio equipment, recording equipment, mechanical interfaces can be selected round pin-row female connectors YC type. 2, the selection of pin-row female connectors, pay attention to the size of the external dimensions, installation dimensions, the size of the opening size, can not be too large, not too small. 3, the selection of contact parts, pay attention to the number of pairs of connectors and the number of needs to be consistent, but also can be a little more, but not too much. 4, in the maintenance of the found to have a damaged In the maintenance found in a damaged pin row mother connector, the first to be based on the repair, and then for replacement processing. Replacement should try to use the same specifications. 5, the selection of row pin row mother connector, pay attention to row pin row mother connector rated voltage, rated current to meet the requirements of the working circuit, and to leave a margin. 6, in the use of row pin row mother connector, pay attention to can not be inserted in reverse or misplaced, when the dial plug is not smooth, can not be forced to pull the plug to prevent damage. 7, in the use of integrated circuits in sockets; be sure to clarify the direction of the premise, and then inserted into the integrated circuits. When using the integrated circuit socket; be sure to figure out the direction of the premise, and then inserted into the integrated circuit, otherwise it will cause damage to the integrated circuit.

Pin row mother, in the electronic connector of all metal elements, copper metal in the conductive material in the best function; silver (about 1.06 times the copper) > copper > gold (about .077 times the copper), but the gold and silver metal, generally only in the connector plating materials used to reduce the touch impedance outside, but also to increase the external white oh antioxidant effect. Copper metal is inexpensive, and good conductivity, so in the wire and cable in the selection of pure copper as electricity, wire, information transmission in a wide range of applications, but also in the electronic connectors in this profession for the best choice of materials pure copper conductivity, although good, but its mechanical strength and heat resistance. Not enough to reach the standard of the connector industry, so the need to add some alloying elements to improve its own mechanical strength and heat resistance, pure copper conductivity is good, but its mechanical strength and heat resistance, not enough to meet the needs of the electronic connector, so we must increase the alloying elements to improve its mechanical strength and heat resistance. However, because of the increase in the metal itself has a specific scale of atoms, when added to pure copper, back to the difference between the atoms and distort the placement of copper atoms, and then lead to a weakened transmission process or blocked. Common on the market are: brass (Cu-Zn); brass (Cu-Sn); white alloy (CU-Ni); but its mechanical strength and heat resistance are better than pure copper. Pin row mother processing requirements for the choice of material as described above, such as the need for this product, welcome to contact the Suzhou Huicheng yuan electronics company's customer service, we try our best to serve you.
