Problems solved by technology

Therefore, in this state, the contact conductor 221 is only insulated by the insulating plate 222, so the insulation distance cannot be obtained, and depending on the situation, the contact conductor 221 may be short-circuited with the plug housing 224 via the cover plate 223.

Embodiment Construction

[0031] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0032] figure 1 It is a side view showing a hybrid excavator 1 as a construction machine according to this embodiment, figure 2 The general structure of the power source used for this construction machine is shown schematically.

[0033] exist figure 1 Among them, the hybrid excavator 1 is configured as a hybrid vehicle including a crawler-type undercarriage body 2 and an upper revolving body 3 rotatably provided on the upper part of the undercarriage body 2 , and is hydraulically driven. The lower traveling body 2 and the work implement 5 described later drive the upper revolving structure 3 by electric energy.

[0034] On the upper revolving structure 3, a box-shaped cab 4 on which an operator rides and a work implement 5 are provided. The work implement 5 is composed of a boom 5A, an arm 5B, a bucket 5C, and a plurality of hydraulic actuators 5D for driving them. S...

Abstract

The present invention provides a connector and a construction machine. The connector (20) is used to connect a power cable for power transmission to an electrical device mounted on a vehicle, and includes: a device-side socket; a cable-side plug (22 ), which is plugged and unplugged relative to the socket on the equipment side; the detection switch (30), which is electrically connected and disconnected by using the mechanical contacts on the socket on the equipment side and the plug (22) on the cable side; on the equipment side The contact terminal of the detection switch (30) is provided on the socket, and the plug (22) on the cable side is provided with: a plug shell (41) electrically grounded by connecting with the socket on the equipment side; covering the plug shell (41) ), the cover plate (43) has: an insulating plate body (51); the contact conductor (52) of the detection switch (30) in contact with the contact terminal, the plate body (51) and the contact conductor (52) are integrally formed.

Description

technical field [0001] The present invention relates to a connector and a construction machine, for example, to an improvement of a connector for a power cable of a hybrid construction machine. Background technique [0002] Conventionally, a hybrid construction machine is known in which a generator motor and a hydraulic pump are driven by an engine, an electric swing motor for rotating the upper swing body is driven by electric power generated by the generator motor, and pressure from the hydraulic pump is used to drive the electric swing motor. Oil drives the hydraulic actuators of the work equipment and the hydraulic motors of the traveling body. [0003] In this hybrid construction machine, electric devices mounted thereon are electrically connected by power cables, such as between a generator motor and an inverter and between an electric swing motor and an inverter (for example, refer to Patent Document 1). Figure 6 A connector 200 for connecting the power cable 10 and ...
