An electrical connector configured to maintain an electrical connection with a conductor during heating and cooling cycles is provided. The electrical connector includes connector sections, each comprising a base portion and top portion extending from the base portion. Each connector section defines a portion of a channel configured to receive one or more conductors and includes a bore in its base or top portion that communicates with the channel. A fastener inserted into the bore is configured to retain the conductor inserted into the channel, and the top portions are configured to deflect substantially independently of each other to provide a spring force that secures the fastener against the conductor.

Electrical connector

An electrical connector configured to maintain an electrical connection with a conductor during heating and cooling cycles is provided. The electrical connector includes a base portion and an arm extending from the base portion. The arm and the base portion combine to define an opening configured to receive the conductor, and one of the arm and the base portion defines a bore communicating with the opening. A fastener inserted into the bore is configured to retain the conductor inserted into the opening, and the arm is configured to deflect to provide a spring force that secures the fastener against the conductor during the heating and cooling cycles.

Electrical connector with cantilever arm

A connector includes a base member and a cap designed to be fitted onto each other. The base member or the cap may have a double-wall configuration to improve stability, strength, and durability of the connector unit as a whole. The base member includes a plurality of ribs forming wire-receiving channels and having at least one groove therebetween. The cap includes a conductive connecting plate configured to fit in the groove of the ribs of the base member. The connecting plate itself includes grooves configured to align with the channels of the ribs of the base member to thereby cut and remove insulation of at least one cable housed in the channels.
