Abstract: The cables are configured to supply electric power from an inverter to a motor. The cables include a connector and plural terminals fixed to the connector. A housing of the connector includes a first rib, provided between the adjacent terminals, connecting mutually facing surfaces of the housing. The terminal block is attached to an enclosure of the inverter or motor. The terminal block includes plural retaining walls, each of which encloses and retains a nut. The terminal block includes a second rib connecting adjacent retaining walls. One of the first and second ribs includes a recess. The connector is connected to the terminal block when each of the terminals is fastened to the terminal block with a bolt and the nut. The other of the first and second ribs is disposed in the recess and the ribs intersect when the connector is connected to the terminal block.

Abstract: A terminal block in which a plurality of conductive plates (10) connected to device-side busbars provided in a motor are made integral by a connector housing (50) made of synthetic resin includes a plurality of cores (65) in which the conductive plates (10) are made integral to a primary molded portion (61); a metal plate (30) to be attached and fixed to a motor case; and a secondary molded portion (70) integrally forming the plurality of cores (65) held in contact side by side and the metal plate (30). A contact portion (66) is provided between a pair of adjacent cores (65, 65) and the pair of adjacent cores (65, 65) are held in contact via the contact portion (66).

Abstract: A terminal block in which a plurality of metal conductive plates (10) to be connected to device-side busbars provided in a motor are made integral by a connector housing (50) includes a primary molded article (60) integrally formed to a primary molded portion (61) made of synthetic resin with a plurality of conductive plates (10) arranged side by side in a lateral direction; a metal plate to be attached and fixed to a motor case; and a secondary molded portion (70) integrally forming the primary molded article (60) and the metal plate (30). Resin entering spaces, into which molding resin for forming the secondary molded portion (70) can enter, are arranged to cross straight parts of the primary molded portion (61) extending in the lateral direction in the primary molded portion (61) before the secondary molded portion (70) is formed.

The secondary molded portion (70) is formed by a secondary molding die including both upper and lower dies (90, 91) and a slide die (92). Pairs of tight holding portions (69, 69) for tightly holding the slide die (92) are provided on the primary molded portion (61) before the secondary molded portion (70) is formed.

Abstract: A mounting structure for a shielding shell (70) is provided for covering a housing (50) to be connected to a motor case. The mounting structure includes a metal plate (30) integrally to the housing (50) and adapted to attach the housing (50) to the motor case by mounting bolts. A first shielding shell (70A) has two overlapping pieces (76) and is adapted to cover the front side of the housing (50). A second shielding shell (70B) includes two fixing pieces (72) and is adapted to cover upper, left and right sides of the housing (50). The overlapping pieces (76) and the fixing pieces (72) are plates extending along the metal plate (30) and fastened together with the metal plate (30) to the motor case by the mounting bolts while being placed one over the other.
