A connector includes an insulation housing formed with a plurality of terminal slots, and a plurality of terminals inserted into the plurality of terminal slots. Each of the plurality of terminals has a pin protruding from a bottom of the insulation housing for insertion into a terminal hole in a circuit board. At least one latch is formed on the insulation housing for insertion and locking into a latch hole defined in the circuit board.

A terminal base includes a straight, strip plate-shaped bus bar having a first end and a second end, the first end having a bolt insertion hole, a bolt configured to be inserted into the bolt insertion hole for electrical connection, the bolt having a head, a housing into which the bus bar is inserted from the second end of the bus bar such that the second end extends out of the housing, an O-ring configured to be mounted on the bus bar at a middle of the bus bar to seal a gap between the bus bar and the housing and a holder configured to regulate a movement of the O-ring. The holder is provided on the bus bar. The holder includes a bolt holding portion configured to hold an outer periphery of the head of the bolt over an entire circumference of the outer periphery of the head.

Disclosed is a terminal block including: a lower bus bar and an upper bus bar that overlap each other at overlap portions and an insulating middle cover disposed between the overlap portion of the lower bus bar and the overlap portion of the upper bus bar, wherein the lower bus bar and the upper bus bar are provided with their respective ones of first to fourth terminals exposed from the middle cover, at positions different from the overlap portions and the first to fourth terminals are disposed at positions radially spaced apart from the overlap portions.

A conductor connecting structure includes: first and second conductors having terminal portions; a support having recessed portions; first screw members accommodated in the recessed portions; and second screw members that co-fasten the terminal portions of the first and the second conductors by screwing to the first screw members. The recessed portions have first and second wall surfaces that face each other in an opposing direction, and restricting surfaces along the opposing direction to restrict the rotation of the first screw members. The first and second wall surfaces configure a retaining portion to retain the first screw member before being screwed, and an allowable portion located closer to the inlet of the recessed portion. The distance between the first and the second wall surfaces in the allowable portion is greater than the distance in the retaining portion.

A connector (10) has a housing (20) including a body (21). A work hole (23) long in a lateral direction penetrates through the body (21). Terminals (30) are held in the housing (20) and are arranged side by side in the lateral direction in the work hole (23). Each terminal (30) includes an embedded portion (31) embedded in the housing (20), an internal connecting portion (32) connected to the embedded portion (31) and disposed inside the work hole (23) and an external connecting portion (33) connected to the internal connecting portion (32) and disposed outside the work hole (23). Protection walls (22) project from the body (21) at both sides of a terminals (30). Tip parts of the protection walls (22) are more distant from the body (21) than the external connecting portions (33) in a penetration direction of the work hole (23).

A terminal block assembly for wire connection of a motor, which includes: a terminal block body; one or more bus bar supports which are formed on the terminal block body; one or more bus bar bodies which have bent shapes corresponding to outer surfaces of the bus bar supports and are rested on the terminal block body or the bus bar supports; one or more terminal connectors which are formed at one ends of the bus bar bodies and are held in contact with one or more connector terminals; and one or more coil connectors which are formed at the other ends of the bus bar bodies and are connected to one or more coils of a motor.

A low profile interposer with multiple electrical contacts held in a housing via a process, such as heat staking, that deforms portions of the housing into protuberances that lock the electrical contacts within openings of the housing. The contacts may be arranged in multiple parallel columns and may have an elongated dimension that is aligned at an acute angle with respect to the column direction. Distal tips of the contact portions of the electrical contacts may be bent to extend into an opening in the housing, even when the electrical contact is in an uncompressed state.

A drive unit includes: a rotating electric machine having a rotation axis extending in a horizontal direction; a rotating electric machine case which accommodates the rotating electric machine; and a power conversion device converting electric power supplied to the rotating electric machine and electric power supplied from the rotating electric machine. The power conversion device is arranged on one side of the rotating electric machine. A first connector portion, to which a power line connected to a battery is connected, is provided on an upper portion of the power conversion device to face the horizontal direction. The first connector portion includes an internal connection portion connected to a conductive member arranged inside the power conversion device, and the first connector portion has a configuration in which the internal connection portion permits access from an upper side of the power conversion device.

A junction box assembly and a terminal assembly configured to prevent a short circuit is provided. In one aspect, the terminal assembly includes a pair of terminals spaced apart from each other and a spacer configured to retain the pair of terminals in a fixed position with respect to each other. In another aspect, the spacer includes a plurality of fuses, and each fuse is electrically connected to a corresponding slot so as to help prevent a power surge through a respective output portion of the terminal. In yet another aspect, the terminal housing has a side wall having a rib extending a height at least as high as the combined height of the output portion and terminal connector when the two are laid on top of each other, preventing the terminal connector from coming into contact with an adjacent terminal connector.

A terminal block includes a housing having sidewalls defining a cavity. One of the sidewalls defines a hole opening into the cavity. A conductor is supported in the cavity and is configured to electrically connect with an inverter. A terminal lug extends through the hole. The terminal lug includes a body having a first end disposed in the cavity and attached to the conductor and a second end external to the cavity and configured to attach to a terminal lead of an electric machine. The terminal lug further includes a support integrally formed with the body and disposed between the first and second ends to be located within the hole. A sealing member is attached to the support and is in sealing engagement with the hole to prevent fluid from entering the cavity
