Abstract

<P>PROBLEM TO BE SOLVED: To provide a grounding conductor strip 3 which is of simple structure and enables many grounding wires 6 to be connected in saved space, being a grounding conductor strip 3 which is built in a distribution board or the like and connects with an electric apparatus 2 such as a lightning arrestor by a grounding wire 6. <P>SOLUTION: For the structure of the grounding conductor strip 3, it is bent in the shape of roughly U so that it may surround the electric apparatus 2, and also it is provided with a plurality of tapped holes 4, thus this grounding conductor strip 3 enables many grounding wires 6 to be connected in the limited space of a distribution board or the like. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention provides a grounding conductor for grounding an electrical device by connecting to a terminal of an electrical device such as a circuit breaker for interrupting a circuit or a lightning arrester for preventing a lightning surge from flowing to a load device by a connecting wire or a connecting conductor. It relates to the structure of the belt.

Conventionally, the grounding conductor 31 is formed in a straight line, and a plurality of screw holes 32 are processed. The terminal portion 34 of the lightning arrester 33 and the grounding conductor 31 are connected by a grounding wire 35, connected from the grounding conductor 31 to the grounding terminal of the load device by a grounding wire 36, and grounded in the cabinet that houses these electrical devices. A main ground line 37 is connected to the terminal, and the circuit is grounded.

  However, the grounding conductor in the above prior art has a long grounding conductor and occupies a wide space in order to connect a large number of ground wires.

  Further, when connecting the ground wire from multiple directions, the distance to the ground conductor is long, and it is necessary to route the ground wire extra.

  Therefore, the present invention has an object to provide a grounding conductor that can connect a large number of grounding wires with a simple structure and space-saving, and the structure is such that the grounding conductor surrounds the periphery of the electrical equipment. It is characterized in that it is bent in a substantially U shape and provided with a plurality of screw holes.

  The ground conductor according to the present invention is formed in a substantially U shape so as to surround the periphery of the electric device, and a plurality of screw holes are provided, so that a large number of ground wires can be connected from multiple directions in a small space. Is possible. Further, the wiring distance between the lightning arrester and the grounding conductor can be shortened, and the grounding wire may be short. During assembly work, man-hours can be reduced, workability can be improved, materials used can be reduced, and production costs can be reduced.

  The purpose of making it possible to connect a large number of grounding wires in a space-saving manner was realized by improving the workability by forming a grounding conductor in a U shape so as to surround the electrical equipment.

  The structure of the grounding conductor according to the present invention will be described with reference to the attached drawing of FIG.

  An electric device 2 such as a breaker or a lightning arrester is arranged on the base 1. These electrical devices 2 can be grounded via the ground conductor 3.

  The grounding conductor 3 is bent in a substantially U shape so as to surround the electric device 2. A plurality of screw holes 4 are provided on the grounding conductor 3. A grounding wire 6 is fixed and connected to the terminal portion 5 of the electric device 2 and the nearest screw hole 4 by screwing or the like. From the grounding conductor 3, a main grounding wire 8 is connected to a grounding wire 7 connected to the grounding terminal of the protected device and a grounding terminal of a cabinet that houses the electrical device 2.

  Since the grounding conductor 3 is bent in a substantially U shape, the space required for the installation of the electrical equipment 2 and the grounding conductor 3 is suppressed, and when installed on a distribution board, it is space-saving and limited. Space can be used effectively. The ground wire 6 is also connected to the ground conductor from multiple directions because the ground conductor is provided in the vicinity of the terminal portion of the electric device 2. Connection is possible with a short grounding wire. The grounding wire enters the panel and is not disturbed, preventing incorrect connections.

  The grounding conductor 3 can be connected to a breaker and a lightning arrester. However, the breaker and the lightning arrester will be arranged in separate systems.

  By bending the ground conductor band into a substantially U shape, the number of man-hours can be reduced in connection work, workability can be improved, and it can be provided at low cost.

It is explanatory drawing which shows the structure of the grounding conductor which concerns on this invention. Example 1 It is explanatory drawing which shows the structure of the conventional grounding conductor.
