Q1:What are connectors?

A1:Connectors are connected to the electrical and mechanical components of electrical circuits.They are widely used in various electrical circuits, plays the role of connecting or disconnecting the circuit.

Q2:What classification do connectors have?

A2: In accordance with the frequency points, a high-frequency connector and the low frequency connectors; in accordance with the shape divided circular connectors, rectangular connectors; in accordance with the zoning, there are connectors for printed boards, cabinets, socket connector, connectors for audio equipment, power connector, connectors, etc. for special purposes.

Q3:What is rated voltage?

A3:Rated voltage also known as operating voltage, which mainly depend on the connector insulation material used, the spacing between the size of contact. Some of the components or devices in less than its rated voltage may not be completed to its functions.

Q4:What is rated Current?

A4: Rated current, also known as operating current. With the rated voltage, as in the case below the rated current, air plug in general can work properly. Plug in the aviation design process, through the thermal design of the connector to meet the requirements of the rated current, because in contact with on a current flow out of date, due to conductor resistance and contact resistance, contact on will be heat. When the heat exceeds a certain limit, the plug will damage the insulation and the formation of air exposure on the surface of the coating to soften, resulting in failure.

Q5:Why choose cnlinko?

A5: Our product have passed UL,CUL,CCC,CE and ROHS certification. Use PBT material that import from abroad with stable,compression, anti-explosion and anti-deformation; Use Zinc alloy material against high frequency noise and electromagnetic interference Use gold-plated contact with high performance of corrosion resistance and electrical conductivity effectively deal with temperature rise.

Q6:Is there cheap shipping cost to import to our country?

A6: For small order,express will be best.And for bulk order,sea ship way is best but take much time. For urgent orders,we suggest via air to airport plus our ship partner send to your door.

Q7:Can we get support if we have our own market position?

A7: Please inform us your detailed mind on your market demand,we will discuss and propose helpful suggestion for you,to find the best solution for you
