A terminal may simply be the end of a wire or it may be fitted with a connector or fastener. "A terminal is the point at which a conductor from an electrical component, device or network comes to an end and provides a point of connection to external circuits. Cable glands, known as cable connectors in the US, connect wires to devices mechanically rather than electrically and are distinct from quick-disconnects performing the latter." In computing, an electrical connector can also be known as a physical interface. ![]() Connectors may join two lengths of flexible copper wire or cable, or connect a wire or cable or optical interface to an electrical terminal. There are hundreds of types of electrical connectors. An adapter can be used to effectively bring together dissimilar connectors. The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or devices. Connectors consist of plugs (male-ended) and jacks (female-ended). ![]() "An electrical connector is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly. Use it for drawing the wiring diagrams, electrical layouts, electronic schematics, and circuit diagrams. This is true regardless of whether the line is balanced, and indeed the shield performance is MORE critical in an unbalanced line obviously, so you are mistaken, the drain is actually more advantageous there, not less so.The vector stencils library "Terminals and connectors" contains 43 element symbols of terminals, connectors, plugs, polarized connectors, jacks, coaxial cables, and conductors. It's the same as with a braided shield, again you could use that as a conductor if you wanted to as well, but for similar reasons it is not designated as a conductor in the cable specs usually.Īnd the drain is not unnecessary at all, it aids the foil shield for the two reasons I explained above. A braided copper shield often has low enough resistance that the drain isn't needed, compared to a foil shield. This is Belden's standard designation as well, the drain is not included in the conductor or pair count, but is designated in the specs, and is usually used on conjunction with a foil shield. So a single-pair (2-conductor) cable with a foil shield+ a drain wire is still normally called a 2-conductor cable (or a 1-pair cable) from any cabling manufacturer I'm familiar with. You could, however, use it as one if you wanted to, or as a common ground for stereo if you so desired. No, the drain is not normally considered one of the conductors. Which pin is it supposed to go to?īottom line, if some manufacturer is responsible for this idea, they should be offering recommendations on cable, connectors or both, to accomplish it. Likewise, going with the single multi-conductor cable route, there will be only one drain wire. If you use eight installation-grade cables, there will be a drain for each of them. But the problem we have there is, it’s doubtful you’re going to find a DB connector that will physically take eight cables stuffed under it, even if you use the relatively thin installation-grade wire. That’s a good idea that could avoid the problems mentioned above. the diagram you attached) calls for drain connections tells me that whoever came up with this expects you to use eight individual cables. In other words, the break-out will be extremely flimsy and fragile. Second, the individual wires to each of the RCAs are going to be an extremely small gauge with no outer jacket. To begin with, for the length of wiring where the individual wires split out to the RCA connectors, there will be no shielding. The problem comes with the break-out to the 8 RCAs. The first option would presumably use a cable with a single, overall shield. ![]() Basically, there are two ways to accomplish it: Either with a multi-conductor cable, or a separate cable for each of the eight channels. Your project in particular has some daunting challenges. The drain wire is terminated as the shield connectionĪlspoll - as someone with extensive experience making custom cables, I don’t really see this project as “doable.” To start with, DB connectors are a royal pain in the neck – not recommended for a novice cable maker in any way, shape or form. Click to expand.It’s standard with installation-grade cable, which uses a foil shield that can’t be terminated to a connector.
