Low frequency connector. Usually refers to connectors that transmit signal frequencies below 100MHz. These connectors have a wide range of transmission currents and are mostly multi wire in structure.

Classification of low-frequency connectors

1. Low frequency connector. Usually refers to connectors that transmit signal frequencies below 100MHz. These connectors have a wide range of transmission currents and their structures are mostly multi wire (up to hundreds of wires), including:

a. Cable connectors. This type of connector is terminated with multi stranded wire cables or shielded cables, as well as solid wires, etc. The free end connector is composed of a free end mating connector or a fixed connector.

b. Cabinet connectors. Composed of two paired fixed connectors. They are installed on the framework of the system and on the unit components, and are connected and separated by the linear reciprocating motion of the unit components.

c. Connectors for audio equipment. There are many types and varieties of this type of connector, such as the YS1 circular connector used in audio equipment, concentric connectors, plugs, and sockets.

d. Connectors for household appliances. This type of connector is mainly used in household appliances such as black and white televisions and color televisions, as well as in devices with similar structures.

e. Connectors for office equipment. This type of connector is mainly used in devices such as copiers, Chinese and English computer printers, microprocessors, etc.

f. Power connectors for electronic and electrical equipment.

g. Environmentally resistant connectors.

h. Special connectors.

2. Hybrid high and low frequency connectors. Usually refers to a connector that includes both low-frequency and high-frequency contact pairs.

Current carrying design of low-frequency connectors

Generally, low-frequency connectors have multiple contacts, with the number of contacts ranging from a few, dozens to over a hundred. The current passing through each contact is an important design parameter for low-frequency connectors. The current carrying capacity of low-frequency connector contacts should not be designed too high, otherwise it will cause excessive temperature rise and insulation damage; At the same time, excessive current carrying safety factors should not be used, as this can lead to situations where large connectors transmit small currents.
