Characteristics of LED lighting connectors

The characteristics of connector products are important. Especially in the LED lighting industry, there are stringent requirements for varying tolerances and environmental robustness. Key features include voltage rating, current rating, plugging and unplugging force, durability and form factor. Rated Voltage: The rated voltage or operating voltage of the connector is the maximum continuous voltage during normal operation and will not cause physical deformation or electrical failure. The voltage rating of the connector is determined by the insulation material characteristics and contact spacing requirements parameters. Rated current: The rated current or operating current of the connector is the maximum current expressed in amps (A), which is determined by parameters such as contact material, contact resistance of the mating surface of the conductive element, and operating temperature. The designer should select a current rating that meets the ambient temperature and heat requirements of the application.

Plug and Plug Force: These characteristics describe the force required to fit and separate a connector pair and are directly affected by connector design characteristics, including lock characteristics, wire gauge, pressure fitting design, and pressure fitting quality. The plug force of the connector directly affects the impact and vibration performance in harsh environments. Durability: The durability of a connector is the maximum fitting period the component can withstand before wearing out to the point of failure. If the connector operates within the rated range and is below the maximum number of fatigue cycles, the specified electrical characteristics must also be stated. Form Factor: The physical size and shape or form factor of the connector is another important mechanical characteristic. Especially in today's smaller, lighter electronic designs. In LED lighting, connectors with large z-axis height profiles generate shadows that negatively affect the quality and clarity of the brightness output. Compact, low form factor connectors also help save motherboard space, incorporating other components and features. In addition, certain new shapes can improve the electrical characteristics of connectors. For example, AVX's insulator-free single-contact solution has a higher current-carrying capacity than an insulated version of the same contact. This helps reduce thermal reliability issues in certain LED lighting applications as it releases heat more efficiently. When choosing to use connectors in the LED lighting industry, engineers must consider the identified connector characteristics, design efficiency, performance and more. Existing connectors may cost better, but today's connectors offer a variety of features and benefits to meet demanding electrical, mechanical, manufacturability, reliability, cost and availability requirements.
