===Soldered connectors===
{{see also|Soldering}}
Many plug and socket connectors are attached to a wire or cable by '''soldering''' conductors to electrodes on the back of the connector. Soldered joints in connectors are robust and reliable if executed correctly, but are usually slower to make than crimped connections.<ref name="ieee" /> When wires are to be soldered to the back of a connector, a [[#Backshell|backshell]] is often used to protect the connection and add strain relief. Metal ''solder buckets'' or ''solder cups'' are provided, which consist of a cylindrical cavity that an installer fills with solder before inserting the wire.<ref>{{cite web |url=https://www.rs-online.com/designspark/field-installable-the-secret-to-mastering-connectors |title=Field Installable: The secret to mastering connectors |website=Design Spark |publisher=RS Components |date=16 March 2017 |access-date=1 July 2019 |at=Solder connectors}}</ref>

When creating soldered connections, it is possible to melt the [[dielectric]] between pins or wires. This can cause problems because the thermal conductivity of metals causes heat to quickly distribute through the cable and connector, and when this heat melts plastic dielectric, it can cause [[short circuit]]s or "flared" (conical) insulation.<ref name="crimp-vs-solder" /> Solder joints are also more prone to mechanical failure than crimped joints when subjected to vibration and compression.<ref name="hpacademy">{{cite web |url=https://www.hpacademy.com/technical-articles/solder-vs-crimping/ |last1=Simon |first1=Andre |website=High Performance Academy |title=Solder Vs Crimping |access-date=1 July 2019}}</ref>
