Abstract (en)
A terminal block assembly for connecting an insulated electrical conductor with a stationary electrical contact, has; <??>(i) a hollow terminal block made of synthetic plastic insulating material and having chamber(s); <??>(ii) a bus bar mounted within the block; <??>(iii) a horizontal resilient electrical contact supported by the bar within the chamber; <??>(iv) a generally U-shaped resilient support spring; and <??>(v) an actuator mounted for movement within the chamber. <??>A terminal block assembly (2) for connecting an insulated electrical conductor with a stationary electrical contact (15), comprises: <??>(a) a hollow terminal block (4) formed of synthetic plastic insulating material and containing chamber(s); <??>(b) a bus bar (14) mounted within the terminal block; <??>(c) a horizontal resilient electrical contact supported by the bus bar within the chamber; <??>(d) a generally U-shaped resilient support spring (22) mounted within the terminal block; and <??>(e) an actuator (26) mounted for movement within the terminal block chamber between engaged and disengaged positions. <??>The contact has a bifurcated end portion provided with a pair of knife edges (16) separated by a slit that extends within a conductor contact portion of the stationary contact. The support spring includes a horizontal base portion that extends in spaced relation below and parallel with the stationary contact; and a pair of vertical leg portions (54) extending upwardly on opposite sides of, and in lateral supporting engagement with, the stationary contact conductor contact portion. The actuator contains a vertical bore for receiving an end portion of the insulated conductor when the actuator is in the disengaged position. The stationary contact is supported within the chamber that as the actuator is displaced toward the engaged position the conductor is laterally supported by the support spring leg portions as the conductor is progressively introduced within the stationary contact slit to cause the knife edges to penetrate the conductor insulation and to come into electrical contact with the stationary contact.
