Q series connector

 

Q series of circular electrical connector are featured by small volume and light weight. The bayonet would be connected quickly. The pins and the down-leads of jack are welded. The operation is simple and convenient. The advanced structure and excellent electrical connection capability of the commodity, with the low price. It is widely used in series of electronic apparatus electrical equipments. All the articles are manufactured according to the electronic industry standard called SJ1744. All the pins and jacks can be exchanged to match your equipment.
