Contacts in high quality din 41612 type h connectors are distributed in three ways: single high-current contacts, multiple parallel low-current contacts and hybrid contacts. Each approach has its advantages and limitations. This article Cornewall connector manufacturers, mainly share the advantages and disadvantages of high quality din 41612 type h connectors distribution contacts!

Special high quality din 41612 type h connectors have the advantage of using a contact whose rated current capacity is on the data sheet. It is required that the tests and standards for all considered contacts must be the same to ensure that the rated current is equal, regardless of the thermal interaction between multiple parallel signal contacts.

Special high quality din 41612 type h connectors Contacts are limited by contact size and termination method, size considerations arise from the need to reduce the resistance of the contact body. There are three resistance sources in the connector, namely, the permanent connection resistance, the body resistance of the contact itself and the contact interface resistance. In signal or small current connectors, the body resistance is usually the main source of contact resistance. Therefore, the message is that the body resistance of the high quality din 41612 type h connectors needs to be significantly reduced. The reason is Joule heat, which is more pronounced at high currents and drives many design and material decisions for power contacts and connectors.

The resistance depends on the conductivity and geometry of the contact spring member. Increasing the cross-sectional area of the connector contacts reduces the contact resistance, which is why high-current contacts are often larger than signal contacts. For the same reason, the conductor that terminates the contact will of course be larger. This increase in size is a limitation of special high-current connector contacts.

In addition, the permanent connection resistance decreases due to the increase in connector contact, conductor size and contact area. However, it is important to ensure that the connector contacts themselves are sized to fit the conductor. If the contacts are used for a certain range of wire or bus sizes, the connector is required to be able to carry the current of the largest conductor size in that range. However, the termination method of the connector can also be more problematic due to the increased size of the contacts and conductors and the need for higher end connections, such as crimped connections or bolted assemblies, which are also the limitations of dedicated high quality din 41612 type h connectors contacts.
