In plumbing situations where one-way flow is desired, it is implemented through other means (e.g. Flows through piping networks can be bidirectional, as in underground water distribution networks which have designed-in redundancy. In other contexts, such as plumbing, one-way flow is not enforced through connector gender assignment. This is an example where male and female connectors have been deliberately designed and assigned to physically enforce a safe network topology. In terms of mathematical graph theory, an electrical power distribution network made up of plugs and sockets is a directed tree, with the directionality arrows corresponding to the female-to-male transfer of electrical power through each mated connection. This gender distinction is implemented to enhance safety or ensure proper functionality by preventing unsafe or non-functional configurations from being set up. a flow of power from one device to another). In some cases (notably electrical power connectors), the gender of connectors is selected according to rigid rules, to enforce a sense of one-way directionality (e.g.
Extension of the analogy results in the verb to mate being used to describe the process of connecting two corresponding parts together.
The assignment is a direct analogy with male/female sexual intercourse, the part bearing one or more protrusions or which fits inside the other being designated male, in contrast to the part containing the corresponding indentations, or fitting outside the other, being designated female. In some cases, the pins on the connector may have the opposite nominal gender to the mounted connector, such as the RCA connector. Sometimes the terms plug and socket or jack are used, particularly in reference to electrical connectors. The female connector is generally a receptacle that receives and holds the male connector. In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally assigned the designation male or female.

#Male to male adapter plus#
If someone has made you one, we’d advise you get rid of it, because it can shock you or someone else, plus it can short out on tinsel or any metal it comes in contact with and cause a fire.Īnother solution is to plug both of the male ends into an extension cord long enough to reach the outlet. The reality is that there are no double male end plugs available on the market because they are dangerous. The problem is that they’ve ended up with the female end of the string of lights by the wall outlet, which is also a female end. If you have need of this type of adapter it means you’ve hung a string of lights backwards.Įvery year we have people come in who already have their Christmas lights up and want to find a double male end plug. Double male end “adapters” are illegal, dangerous and a fire hazard.
