Abstract
The electromagnetic clutch (10) includes a rotor assembly (12), an armature assembly (14) and a field assembly (16). The field assembly (16) includes a ring and flange assembly (86). A terminal passage (104) is provided through the base portion (100) of the circular ring 96 with a U-shaped cross-section that form as a toroidal chamber (98). An electromagnetic coil (90) is encased in a bobbin (88) and a cap (92) and inserted into the toroidal chamber with a bobbin terminal post (110) extending into the terminal passage (104). A terminal housing (120) with a terminal sleeve (142) telescopically receives the bobbin terminal post (110) and the terminal sleeve (142) extends into the terminal passage (104). Leads (112 and 114) from the electromagnetic coil (90) extend into the terminal housing (120). Terminals (122) are housed in terminal apertures (136 and 138) in the terminal housing ( 120) and are in contact with the leads (112 and 114). A terminal cover (124) holds the terminals (122) in place and rotatably and axially fixes the terminal housing (120) relative to the ring 96. The terminal cover (124) is clamped to the ring (96) and held in a fixed position relative to the ring.
