Some knowledge about electronic connectors

In the electrical and mechanical industry and manufacturing, each of a pair of mating connectors or fasteners is typically designated as male or female. A "female" connector is typically a socket that houses and holds a "male" connector. Sometimes the connector pairing terms "male" and "female" are called the end of A and B respectively, and some standard names also conflict with this because they contain the letters A or B in the name; but it is rare, the term includes Plugins and sockets or jacks, although this can be confusing when used in everyday sessions.

In some cases, the electrical flow of an electronic connector from one device to another will select the gender of the connector according to strict rules to enforce a one-way sense of direction. This gender distinction is implemented to enhance security or ensure proper functionality by preventing unsafe or non-functional configurations from being set up. In the case of mathematical graph theory, the power distribution network consisting of a plug and a socket is a directed tree, and the directional arrows correspond to the electrical conversion of the electrical to the mother through each mating connection. Male and female connectors are deliberately designed and distributed to physically implement a secure network topology without forcing a one-way flow through connector gender assignment. The flow through the pipeline network can be bidirectional, as in a groundwater distribution network with design redundancy. It is desirable in the case of a one-way flow conduit, which is achieved by other means, such as gravity flow, one-way check valves, rather than through a male-female gender regime. Let's talk about the sex of the connector's mechanical fasteners and the gender choice in the electronic connector design!

Connector mechanical fastener gender

In the mechanical design of the connector, the prototype "convex" component is a threaded bolt, but the alignment post, mounting boss or sheet metal joint connector can also be considered convex. Accordingly, the nut, the alignment hole, the mounting groove or the metal plate slot connector are considered to be negative. While the mechanical design of some connectors is a "one-off" custom setup and is not intended to be repeated, the entire fastener industry is dedicated to manufacturing mass-produced or semi-custom components. To avoid unnecessary confusion, the traditional definition of fastener gender has been defined and agreed upon.

Gender selection in electronic connector design

Electronic connector designers often choose female jack connectors to be fixedly mounted on the electronics they design. This is usually because the female connector is more resistant to damage or contamination due to its hidden or recessed electrical contacts. Damaged motherboard connectors can result in the disposal of expensive electronic equipment. The risk of costly damage can be reduced by downgrading more exposed male contacts to the connecting cable, which can be repaired or replaced at a lower cost.
