In many cases these terms are more common than male and female, especially in documentation intended for the non-specialist. Where the relationship is equal, such as when two flexible cables are connected, each is considered a plug. 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. Commercial Electric CE Wire Connector Blue Qty 75 . Some audio multicore cables are fitted with hermaphroditic multipin quick-disconnect connectors for ease of use in the field. But we need an in-depth discussion of what the new terminology should be. Other people say the female coaxial connector is more prone to damage.[11][12]. Adding to this potential for confusion, some gender changers also combine additional functions such as cross-over pin-outs or even embedding micro-controllers for performance, or for logic level or protocol adaptations, which would properly make them an adapter, but this nomenclature is sometimes neglected in marketing materials or common parlance. Easily adapt your RV's 50-amp power cord for use with a 30-amp outlet. In a different design, if the power adapter were intended to supply a voltage sufficient to cause electrical shock, the semi-exposed center contact of the female plug would be considered unacceptably hazardous, requiring a different choice of power connector. In the United Kingdom, for example, the connector on the end of a headphone lead is known as a "jack", that plugs into a socket on the main unit. Straight-blade plugs and connectors are compatible with straight-blade receptacles and are used in residential, commercial, and industrial applications.

The older PC/104 embedded PC modules use a similar stackable format for interconnection. [15] A specific gender changer can be referred to by either the gender of its connectors, or the gender which it is designed to connect to, resulting in a thoroughly ambiguous terminology. Mechanical interlock devices are receptacles that allow compatible plugs to be attached only when the power is turned off, and they prevent the plug from being removed from the receptacle while the power is on.

A male plug, with fully exposed protruding contacts, is installed on the cord of (or directly onto) the device receiving the power. Typically, the airflow through a ductwork connection is from male to female. A unique connector configuration where the contacts are hermaphroditic is the ELCO Varicon where the contacts are bifurcated and nest with one another axial at a 90 degree rotation in cross-shaped wells. Kapla or KEVA planks are extremely simple genderless systems interconnected only by gravity. Similarly, a male standard-density D-sub with a size 1 shell can be named DE9M or DE9P; a female standard-density D-sub with a size 2 shell can be named DA15F or DA15S; a male high-density D-sub with a size 3 shell can be named DB44M or DB44P; and so forth.

Sheet metal ductwork for conveying air in HVAC systems typically uses gendered connections. The Connectors, plugs... are conductive pieces used to connect two or more conductors by adjustment.They usually consist of a male connector and a corresponding female connector. Stickle bricks, using interlocking plastic protrusions, are effectively genderless. [13] Another style of connector uses hybrid male/female pins with a receiving slot fitted in the center of each two-tine pin, and relies on 90-degree rotation of the pin axes to mate. Have any Questions? In the case of electrical power connections, designers do not reverse connector gender in such a casual fashion, because exposing live AC line power on male connectors is unsafe and generally illegal. Shop Plugs & Connectors top brands at Lowe's Canada online store. In plumbing fittings, the "M" or "F" usually comes at the beginning rather than the end of the abbreviated designation.

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. However, since one-way flow is implemented by forced-air fans or blowers, "backwards" gendered connections can be seen frequently in some systems, since all connections are typically sealed with duct sealing mastic or tape to prevent leakage anyway. Correspondingly, a threaded nut, an alignment hole, a mounting recess, or sheet metal slot connector is considered to be female. In this case the connector is designated a jack (J ref des) regardless of the contact gender because the housing for the contacts is in fact configured as the receptacle even though its mate (the plug) goes around the receptacle.

Get the best deals on Electrical Plugs when you shop the largest online selection at eBay.com. Such cost and reliability considerations probably drove the design decision to use female jack connectors on many computer terminals (and some personal computers) for the serial port, in direct violation of the connector gender convention specified in the RS-232 standard for "DTE" computer equipment. For example, a female high-density D-subminiature connector with a size 1 shell can be named DE15F or DE15S (see accompanying pictures). Some electrical connectors are hermaphroditic because they include both male and female elements in a single unit intended to interconnect freely, without regard for gender. Find a Store Near Me. For the same reason, several spacecraft docking mechanisms are designed to be "androgynous", Depending on the design of the power adapter, it may react to a short circuit by shutting down temporarily, or instead by blowing out an internal safety fuse. ], the word "jack" may refer to the plug on the end of a removable cable.
