CN203690548U - Guide-rail-type wiring terminal - Google Patents

Abstract

The utility model relates to a guide-rail-type wiring terminal and mainly solves a problem of lead pin and terminal burning caused by resistor contact and temperature rise due to poor contact since a lead pin on an inserting end of a plug-type wiring terminal is not easy for aligning in a plugging or unplugging process. The guide-rail-type wiring terminal includes a wiring terminal support connected with a circuit breaker body, a wiring terminal connecting block provided with a slot and an inserting end terminal fitting the slot. The wiring terminal connecting block is fixed on the wiring terminal support. Mounting rails are arranged outside the terminal. Two sides of the wiring terminal support and two sides of the mounting rails are provided with guide rail assemblies used for leading the inserting end to align and fit with and the slot. According to the utility model, a guide rod sleeve and a guide rod are added. Alignment for the inserting end and the slot is prepared in advance through alignment and socket cooperation of the guide rod and the guide rod sleeve before the inserting end contacts the slot, so that displacement is not easy to occur after the inserting end fits with the slot. A shortcoming of being easy to break is overcome and a potential safety hazard of poor contact is eliminated.
