This is the seventh installment in the series of [[:Category:Cursed Connectors|Cursed Connectors]] and presents Cursed Connectors #46: The Sheet Bend. At the time of release this was the lowest number used for a cursed connector, with #286: [[2507: USV-C]] being the one with the highest number after those seven comics.

This comic shows two double-core wires being joined to make an electrical connection. Instead of the join being made the conventional way, that is, silver being joined to silver and gold being joined to gold within the insulating white cable, the diagram shows each core being connected to a ductile outer sheath, then the wires being tied together such that the outer sheaths touch and the connection is completed that way.

This is not the way electrical connections are usually made, as you might get an electric shock from touching the outer side of the wires, if the current being passed was significant enough, and the possibility of contact between any of the wire's conductors and any other item (bridging gaps, leaking signal or possibly even ''introducing'' external interference) could be problematic for both high and low ampage cables (e.g. used to transmit power or just signals). Most connectors, even those like the relatively exposed {{w|punch-down block}} or {{w|screw terminal block}} types, would use some structural housing (and even {{w|AC power plugs and sockets#Protection from accidental contact|other methods}}) to ensure that the 'live' ends of a socket/plug/hybrid terminator are not trivially contactable to other exposed wires or objects/people, generally according to the relative dangers from, or to, the equipment to which the cable is connected.

If this knot were tightened, the gold and silver connectors would probably touch, shorting out the circuit, but there is also the possibility of the cable slipping loose (perhaps by improper tensioning or handling of the knot, from the start) and the exposed conducting sheaths making other improper/dangerous connections across or beyond the knot itself. In both cases, the connection of the 'connector' would be at least become unreliable, even if it only disconnected the intended contact-points due to slippage – whether or not it became mechanically untied.

The knot used to tie the two halves of the cable is a {{w|sheet bend}}, which is often used to join two ropes of different thicknesses, and explains the name for this type of cursed connector.

The title text says that a left handed sheet bend would provide a weaker connection. An actual left handed sheet bend provides less strength to the knot. This makes the title text a pun on the double meaning of "moderate load" (as in a moderate amount of physical tension applied through the cables ''or'' a moderate amount of electrical current passing through them). The difference between a left handed and right handed sheet knot is the free ends of the knots are on the same side in a right handed sheet knot (here both on the bottom side), but on opposite sides in a left handed sheet knot.

:[Above the drawing there is a header. Below the header there is a double-core wire going in from the left and stopping just past the middle of the picture. It shows how the inside of the wire looks and how the silver and golden wires inside are connected to two rectangular pieces of silver and golden material respectively. The golden piece is to the left and the silver piece to the right, closest to the end of the wire. Beneath this wire is shown two double-core wires forming a knot of the sheet bend type. Here it becomes clear that the silver and golden pieces are on the outside of the wires (but connected to the wires running inside the wires). In the knotted part of the wires gold touches gold and silver touches silver, without them touching the other color. Beneath this knot there is a label for the connector.]

-This comic shows two double-core cables being joined in a knot to make an electrical connection. The knot used to tie the two halves of the cable is a {{w|sheet bend}}, which is often used to join two ropes of different thicknesses, and explains the name for this type of cursed connector, which seems to be made by ensuring each cable end is terminated with identical electrical connections to the outer sleeving in a manner similar to various 'ring' connections in {{w|Phone connector (audio)|'phone' connectors}}, but as significantly longer and more separated sleeves.

-In contrast to more normal methods, [[Randall]] has proposed yet another of his 'cursed' connectors. This one requires ''no'' additional plugs, sockets, enclosures or even tools to use. Any two cables with such ends can be brought together and simply knotted together. This particular knot, and the specific spacing of its two external conductors, appears to be chosen in order to rather elegantly create consistent connections between the respective contacts, with a minimum of fuss.
+This is not the way electrical connections are usually made, as you might get an electric shock from touching the outer side of the wires, if the current being passed was significant enough, and the possibility of contact between any of the wire's conductors and any other item (bridging gaps, leaking signal or possibly even ''introducing'' external interference) could be problematic for both high and low ampage cables (e.g. used to transmit power or just signals).

-However, there are potentially many unaddressed but conspicuous problems with this connection method, thus rendering it a 'cursed' connector. Among the issues are:
+If this knot were tightened, the gold and silver connectors would probably touch, shorting out the circuit, but there is also the possibility of the cable slipping loose (perhaps by improper tensioning or handling of the knot, from the start) and the exposed conducting sheaths making other improper/dangerous connections across or beyond the knot itself. In both cases, the connection of the 'connector' would be at least become unreliable, even if it only disconnected the intended contact-points due to slippage – whether or not it became mechanically untied.
-* The need to have suitable ends to any cables, which would involve issues in the manufacture (and the materials used) as cable's cores must be separately tapped and reliably connected to an external length of conductive sleeving.
-* The consistent ability of a cabler to tie the correct knot, which is a skill that will need practice. Done wrongly the electrical connections may not be made correctly, or at all (including as discussed in the title text).
-* Even if initially tied correctly, knots can slip or distort when subsequently pulled more taut.
-* Even if the user is a competent and consistent knot-tier, this is inherently more effort, and therefore less convenient, than the more usual practice of simply pushing two connectors together.
-* The external conducting patches of the cable are an uncommon feature of electrical junctions, with issues in both high-power and low-power situations.
-** If the cables are supposed to carry high voltages, any bare conductors ought to be safely isolated from easy contact with equipment/people. In particular, plugs and sockets that carry anything approaching mains-voltages have active and passive elements integrated which protect the person connecting or disconnecting the equipment. There is no physical precaution visible to protect the person tying or untying the cable from potential shock. Instead, they must rely upon the ''other'' end of the potentially 'live' cable being disconnected. And, when left unattended, there would continue to be a high risk of injury (including death), fire or more basic damage due to the lack of any proper physical isolation.
-** Low-voltage cables that pass signals between equipment (e.g. networking data or audio signals) are susceptible to external contact disrupting the flow. Random static charges, built up and transfered into the connector, instead make other equipment or people the potential threat to the cabled-up equipment, causing disruption to the normal purpose of the cable, where a more standard plug-and-socket/hard-wired connection would not.
-* The bending, twisting and rubbing of the cables each time the cables are connected and disconnected will very likely cause wear and damage over time.
-* The knot provides a possible snag point by which the cable could be caught; anything which catches or tugs on the knot could cause disconnection.
-The title text says that a left-handed sheet bend would provide a weaker connection. The difference between a left-handed and right-handed sheet knot is that the two free ends of the knotted 'cords' are in the same orientation for a right-handed sheet knot (here, both on the lower side of the image), but on opposite sides for a left-handed sheet knot. A left-handed sheet bend provides less strength to the knot, due to the possibility of distorting (e.g. {{w|Knot#Capsizing|''capsizing''}}) and/or allowing one or both cables to pull through the knot.
+The knot used to tie the two halves of the cable is a {{w|sheet bend}}, which is often used to join two ropes of different thicknesses, and explains the name for this type of cursed connector.
-This makes the title text a pun on the double meaning of "moderate load", which could be a moderate amount of physical tension applied through the cables ''or'' a moderate amount of electrical current passing through them. Together, it would be expected that tension drawing two conductive surfaces together would create less resistance between them, strengthening the electrical connection as well, but only if the knot holds as expected.
