A high-performance connector provides an efficient electrical connection and helps to protect equipment from damage or malfunction. It should also be able to withstand environmental factors such as water and dust, mechanical stress, corrosive environments and a high number of mating cycles. The key characteristics of a high-performance connector include:
Contact spring: The contacts, or pins, in an electrical connector are mechanically formed by the contact spring. This spring is a rigid element that deflects the receptacle contact to generate the contact normal force, which is required to achieve proper alignment during mating. The contact spring should be constructed of a durable material that minimizes resistance and maximizes conductivity for optimal signal transmission.
Insulator: The insulator is an essential Souriau component that separates and protects the pins from each other, as well as other components inside the connector. It should be made from a durable and non-conductive material that is abrasion resistant to prevent damage. Insulators can be made from a variety of materials including polyphenylene sulfide (PPS), teflon, polybutylene terephthalate (PBT), acrylonitrile butadiene styrene (ABS), liquid crystalline polymer (LCP), or polycyclohexylenedimethylene terephthalate (PCT).
What are the key characteristics of a high-performance connector?
Shell: The shell is the outer covering that protects the built-in insulating mounting plate and pins from physical damage. It also ensures that the plug and socket are properly aligned after mating. It can be made from various materials including plastics, metals and composites. Some common shell materials include polybutylene terephthalate, liquid crystalline polymer, FR-4, and polyethylene terephthalate (PET).
The design of a connector can influence its performance and reliability. The shape of the housing can impact the size and weight of the connector, while the material can determine its ability to withstand different environmental conditions. For example, some plastics are better able to resist chemicals than other materials, while stainless steel is more able to withstand mechanical stresses and corrosion.
Other important design features to consider for a high-performance connector include: Insertion and withdrawal cycles: How many times can the connector be inserted and unplugged without damaging it? The higher the cycle durability, the more reliable the connector is. Noise and vibration: Choosing a connector that can withstand noise, vibrations, or shocks will help to ensure a stable connection and reduce the likelihood of accidental disconnections or intermittent faults.
EMI and RFI shielding: If the connector will be used in an environment with electromagnetic interference or radio-frequency interference signals, it is important that it has effective EMI/RFI shielding to avoid disrupting these signals.
Lane is an approved Souriau assembler and offers a large range of Souriau 8D/38999 and Souriau 8STA HD circular connectors that are suitable for harsh and critical applications such as aerospace, industrial and automotive. They are available in six shell sizes, with contacts ranging from size 26 to 3A and are constructed of gold plated copper alloy and have a silicone rubber insulator and seal. The connectors meet MIL-DTL-38999 and are designed for use in a wide variety of industries and are rated up to 1000 mating cycles.
