Abstract
An electric switch assembly including a multipolar quick-assembly appliance and a quick-connect appliance, wherein the body of an appliance, or its power terminal strip, is directly fixed and interlocked with to the body of an adjacent appliance. The interconnection between the various appliances is rapidly performed by multipolar blocks capable of being pressed on the front surfaces of appliances and being elastically plugged into their terminals.
Claims11
An electric switch assembly comprising:
- two multipolar appliances, each comprising an external body having a front face, with upper and lower transverse faces, side faces and a rear face for fixing to a support, at least one of the appliances having breaker properties;
- polar power links comprising internal power conductors housed in the body and upstream and/or downstream power connection terminals having apertures that open onto the front face for connecting external conductors to the power conductors, wherein:
- coupling means are located for mechanically coupling both appliances together,
- a multipolar interconnection block is attached to at least one of the front faces of the coupled appliances and comprises pins plugged into power terminals facing the matching poles for ensuring respective polar links between the appliances,
- the pins of the block and the power connection terminals facing each other to cooperate by a resilient effect, and
- a power terminal strip comprising the power terminals is fixed to the external body of at least one of the appliances for partly or entirely forming, by its upper or lower face, the upper or lower transverse face of the at least one of the appliances, and the coupling means comprise fitting means with protrusions or slots located on an upper or lower face of the power terminal strip.
An assembly comprising two superimposed switch appliances, each having an external body with a front face located thereon, a rear face, upper and lower transverse faces and side faces, and means for fixing one of the appliances to a rear support, wherein:
- one of the appliances comprises a power terminal strip as an insert on an external body and terminals located close to and opening onto the front face of the external body through passages for connection,
- the power terminal strip comprises upper and lower power terminal strip portions, wherein
- the lower appliance is directly fastened to the upper appliance by the lower power terminal strip portion located on the upper plane face of the lower appliance, with first protrusions or slots for fitting into second protrusions or slots of a first complementary shape located on the lower face of the upper appliance, and
- the upper appliance is directly fastened to the lower appliance by the upper power terminal strip portion located on the lower plane face of the upper appliance, with third protrusions or slots for fitting into fourth protrusions or slots of a second complementary shape located on the upper face of the lower appliance.
