Attach the connector to the wire by applying pressure.Place the connector onto the exposed length of wire.Use these cuts as leverage to peel back the jacket and then the wire braiding beneath, going back the same length as the connector Make a small incision towards the end of the cable, deep enough to expose the underlying copper, and then a second cut in the outer jacket of the cable – in both cases being careful not to cut into the underlying layers. Prepare the coaxial cable, using a wire stripper or similar device.It may respond to a simple twist or you may need to make use of a tool such as a construction knife or wire strippers If there is already a connector in place, remove it.Electrical shocks and injuries could result from adjusting a live coaxial cable Ensure that the cable is removed from any power sources.How Do You Connect or Change a Coaxial Connector?Ĭoaxial cables and their corresponding connectors have different uses but the fundamentals of connecting or replacing them remain much the same. They are not the right choice for installations in which a carefully controlled flow of current in a single direction is required for safety or functionality reasons. Genderless coaxial connectors are also known as combination connecters. They have a reverse electrical polarity, with a pin protruding from the female socket and slot in the male plug designed for that pin. They allow cabling within complex installations to be repurposed or reconnected quickly, without awkward removal and repositioning if it needs to be connected to a different component or cable. Genderless coaxial connectors combine male protrusion points and female slots in the same connection point, enabling these to be connected to either male or female connectors of matching size and type. The latter functions as an electrical contact point, alongside the inner tube. This is surrounded by an insulating layer and then an outer cylinder, typically referred to as the barrel or sleeve. Male coaxial connectors typically have a straightforward design, combining a central pin designed to fit a compatible plug on the female connector, alongside a spring-loaded electrical contact point located at the side.įemale coaxial connectors normally feature a metallic tube designed to precisely contain the corresponding male pin, normally called the tip. Widely used electrical standard IEC60320 does not specify gender types for the latter. Note that the terms ‘male’ and ‘female’ are not universally used, especially in relation to lower voltage domestic appliances. Typically, female connectors are more resistant to damage than male ones so these tend to be placed in crucial areas with males relegated to connecting cables, which can be replaced more easily. Connecting a male to a female connector is referred to as ‘mating’ them.Ĭoaxial cable genders were designed not just to allow physical connections but also to ensure that power or signal data flows in the correct direction, from male to female connectors with matching electrical polarity, preventing interference and unsafe installations. The former typically have a connecting pin or protrusion of some kind that is inserted into indentations or slots in the latter – for example, plugs and sockets (also known as jacks). In electrical engineering, coaxial and other electrical cables are conventionally divided into two types: male and female. Male connectors have protruding metal pins while female connectors have a recess designed to receive the pins Whether a male or female connection is required.When selecting a coaxial connector, you will need to know the key parameters of the cable you plan to connect. The former is primarily used for video signals and the latter for data.Ĭoaxial cables can come in many sizes, including: Most coaxial cables have an impedance of either 75 or 50 Ohm. Impedance refers to the level of electrical resistance in the wire. Gauge refers to the thickness of the cable and is given a given a Radio Guide or RG number, with higher numbers indicating thinner conducting cores. Coaxial cables are the default cabling choice for many low voltage consumer electronics.Ĭoaxial cables are available in a variety of types, distinguished by their gauge and impedance. Their design allows rapid signal transmission (around 10 megabits per second) with minimal electro-magnetic interference or signal loss. They contain an inner conducting wire, usually copper, surrounded by a protective double insulating layer and then an outer plastic sheath, giving them a distinctive appearance.Ĭoaxial cables are durable, easy to install, and have a broad range of uses. Coaxial or coax cables are electrical cables created to carry high frequency, multi-megahertz electrical signals.
