Apparatus direct mounting connector

Abstract

It is possible to reduce the size of an inverter (apparatus) and a connection structure for connecting two motors. There is provided an apparatus direct mounting connector having six independent bus bars (21-26) for connecting two auxiliary apparatuses and one apparatus for 3-phase AC. Two terminal units (11, 12) of the U pole, two terminal units (13, 14) of the V pole, and two terminal units (15, 16) of the W pole of the 3-phase AC to be connected to an apparatus are arranged adjacent to each other, respectively. Each of the terminal units (11-16) is arranged at first end of each of the bus bars (21-26). At the second ends of the bus bars, two sets of terminal units (31-33, 34-36) each set consisting of the U pole, the V pole, and the W pole for connecting the two auxiliary apparatuses are arranged apart from each other. The bus bars (22, 25) have extension portions (22c, 25c) extending between the two sets of the terminal units (31-33, 34-36) at the second end side. The bus bars (21-26) are molded into the insulation resin portion.

Description

technical field [0001] The present invention relates to a connector for direct mounting equipment having a bus bar for connecting two three-phase AC motors (auxiliary machines) and an inverter (equipment) of an electric vehicle, for example. Background technique [0002] 11 to 12 show a conventional direct-mounting device connector (for example, refer to Patent Document 1). [0003] The direct installation equipment connector 61 is arranged on the housing (indicated by symbol 64) of the converter (equipment) 64 for connecting the three-phase AC motors 62, 63 (FIG. 13) of the electric vehicle, and has a connection with the equipment side. The three busbar terminals 68-70 corresponding to the UVW three-pole circuits 65-67 (Fig. 4), the wires 73 with terminals connected to the busbar terminals 68-70 by bolts 71, and the insulating resin for accommodating each terminal 72 The casing 74 and the sealing cover 75 made of conductive metal for covering the outside of the casing 74 ....

AI Technical Summary

Problems solved by technology

[0013] However, in the above-mentioned conventional (FIG. 11-FIG. 12) direct mount device connector and connection structure using it, for example, as shown in FIG. The wiring (wiring) of circuits 65 to 67 such as bus bars connecting the equipment main body (inverter) 64a and each pole (UVW) of each connector 61, 61' is complicated, and the equipment 64 is enlarged.

In addition, since the circuits 65 to 67 are complicated, the connection operation is troublesome, requiring many man-hours, and connection errors may occur.

[0014] In addition, the circuits 65 to 67 in the equipment are used to manage the current value, and a current sensor for the management is installed in the equipment, so the size of the equipment 64 is increased.

[0015] In addition, the busbar structure 110 of the above-mentioned conventional (FIG. 15) is connected to the connection conductor and the connection plate via the terminal plate, but for example, when the busbar structure 110 is applied to a connector for direct mounting equipment (substantially no ), in order to arrange one end portion 116 of the bus bar 113 in the housing of the device 121 shown in FIG. The horizontal direction protrudes in parallel up and down, and in this state, the opposite side connector (connector on the opposite side) 123 is connected from the protruding direction (horizontal direction) of the other end portion 119 of the bus bar 113, and the connector connection structure may protrude toward the bus bar protruding direction. hypertrophy problem

[0016] In addition, as shown in FIG. 17 , when two busbars 124 are bent upward in the connector 125 for direct mounting equipment, and the opposite side connector 126 is connected downwardly, since the other end 127 of each busbar 124 The front and back are arranged in two rows, so there is a possibility that the connection structure, that is, the problem of enlargement of the arrangement direction (horizontal direction) of the connectors 125 for direct mounting equipment at the other end 127 of the bus bar may occur.
