A meter collar adapter may include an upper assembly having a housing to protect inner electrical components from adverse environmental conditions and a lower assembly to house electrical components, one or more conductors that pass through at least the lower assembly. Each conductor includes a first end to electrically interface with a meter socket and a second end to electrically interface with an electrical meter. The meter collar adapter further includes thermally conductive heat sinks to transfer heat from the lower assembly.

An electrical connector includes a male element and a female element configured to form a rivet for fastening the electrical connector to a piece of material; and a neck washer, which has a washer portion and a neck portion and which is configured to be placed between the male element and the female element of the rivet. The washer portion is configured to form an electrical connection area for an electrical conductor of the piece of textile and the neck portion is configured to electrically connect the washer portion to at least one of the male element and the female element. The electrical connector can be used independently of the position of the electrical conductor in relation to one or more layers of materials in the piece of material.
