The contact part of Murr connector is the part of the connector to complete the electrical connection function. Generally, the contact pair consists of a positive contact and a negative contactThe electrical connection is completed by inserting and closing the negative and positive contacts. For a one-piece printed circuit connector, the positive contact is the line at the edge of the printed circuit boardContact strip. The male contact is a rigid part, and its shape is cylindrical (round pin), square cylindrical (square pin & gt; or flat (insert). positiveThe contact parts are generally made of brass and phosphor bronze, and the processing technology is turning (round pin, new technology also uses copper sheet punching and curling) or punching（Square pin, insert piece). The female contact, namely the socket, is the key part of the contact pair. It depends on the elastic structure to produce elastic deformation when it is inserted with the pin It can produce elastic force and form close contact with the positive contact to complete the connection.

The basic categories of Murr connectors represented by Qingdao sured are as follows:
1. Cable connector: this type of connector can connect the connector with cable with the connector on the chassis, through wall connector or another connector with cablePlug in the connector.
2. Cabinet connector: this kind of connector is generally used for drawer cabinet, plug-in components and other applications that are difficult to plug in the connectorUse the occasion.
3. Printed circuit connector: this type of connector is used to interconnect the printed circuit board with the cable, rack or backplane.

4. Coaxial connector: in RF and audio circuits, if you want to maintain a stable, predetermined impedance and capacitance, or need to shield the external electrical dryInterference, you must use coaxial connectors to interconnect.

The above is a brief introduction to the basic categories of Murr connectors. In addition, we also act as an agent for electronic products such as device optical instruments and HARTING industrial connectors. Customers who need them can call at any time.
