HA1521500000G

HA1521500000G (hereinafter referred to as HA series) is a terminal block product with the application of the wire-to-board terminals, where the wire-to-board connection and control are needed. It belongs to the category of plug-in terminal blocks. In essence, its construction is very simple, while still being reliable and therefore it is vast in application including home appliances, automotive, information technology, industrial control and other fields.

The overall design of the HA series terminal blocks is a two-piece structure. It consists of two parts, the insulation plastic part and the metallic part. The insulation body of this series is made up of self-extinguishing polyamide 6.6 material. The metallic body is made up of zinc-plated steel which ensures excellent contact and connector. The overall construction of HA series terminal blocks provides excellent retention and a secure mating due to a mechanical retention force that resists against pull-offs.

The working principle of HA series terminal blocks is quite straightforward and it is based on electrical interference. It primarily comprises of a socket, a spring, a column, an insulation sleeve and a plate. In order to make a connection, the plug should be inserted into the socket with the contact spring between two plates. When the assembly is in the fully-closed position, the contact spring will be compressed and make contact between column and plate, thus completing the connection. The insulating sleeve prevents the contact spring from vibrating and it ensures that the contact spring will not be damaged.

The HA series terminal blocks are widely used in the fields of computers, communications, machine building, home appliances, transportation, electronic products and audio-visual products. Furthermore, it is very commonly used to link electric wires with printed circuit boards, enabling a reliable connections. Customers can also order custom specifications of the HA series terminal blocks for their needs, depending on the exact type of their wires.
