SWITCHING DEVICE WITH SEVERAL REGIONS OF CONNECTION

摘要

An electromagnetic switching device, with several distinct regions (10, 20, 30, 40), where each region separates and places the terminals and the connection means in an improved form which make easy the identification of the terminals for the user when the contactor is fixed inside the panel; where the first region (10), have function of fixing the contactor on the panel and also houses the electromagnet; a second region (20) comprising the power terminals (21); a third region (30) that houses the auxiliary terminals (31, 32) and the command terminals (33); a fourth region (40) that is used for the connection of accessories; the third region presents a clear distinction between auxiliary terminals (31, 32) and command terminals (33), given by the asymmetry created viewed from the top; combined with a proposed uneven disposition X1 and X2 of the command terminals (31, 32) and auxiliary terminals (33) viewed from the front in the same third region.

主权项

1. An electromagnetic switching device with several regions of connection, including a contactor having a plurality of command terminals and one or more auxiliary terminals wherein the contactor provides a visual distinction between the command terminals and the auxiliary terminals, the device comprising:
a first region, wherein the first region includes a base that is adapted for fixing the contactor to a panel, and a housing that accessibly encloses an electromagnet, the electromagnet comprising a fixed armature and a coil; a second region, wherein the second region occupies an area located substantially above the first region and is releasably attached to a top of the first region, the second region further comprising a plurality of power terminals, each power terminal adapted to receive a power conductor, and a plurality of moveable power contacts, each moveable power contact being associated with one of the power terminals and adapted to controllably close a circuit associated with the power terminal; a third region, wherein the third region occupies an area located substantially above the second region and comprises the command terminals and the one or more auxiliary terminals, the command terminals being electrically connected to the coil and located at a first height above a bottom of the third region, and the one or more auxiliary terminals being located at a second height above the bottom of the third region, the first and second heights being different from each other, and wherein the command terminals and the auxiliary terminals are distributed across the third region in an asymmetrical manner that groups the auxiliary terminals together and leaves the command terminals standing apart from the auxiliary terminals so that the command terminals are visually distinguishable from the auxiliary terminals; and a fourth region, wherein the fourth region occupies an area located substantially above the third region, the fourth region being adapted for connection of accessories.
