Problems solved by technology

[0008] However, in the above-mentioned previous example, a space for placing the power distribution box 130 is required on the top surface of the server rack 120
However, if an air conditioner for cooling the devices (servers) in the rack is installed on the top of the server rack 120, and the distance from the ceiling to the top of the server rack 120 is shortened, the power distribution box cannot be installed. 130
Alternatively, if the strength of the roof portion of the server rack 120 is insufficient, it will be difficult to place the power distribution box 130

Embodiment Construction

[0059] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings constituting a part of this specification. In all the drawings, the same reference signs are attached to the same or similar parts, and explanations thereof are omitted.

[0060] Such as figure 1 As shown in (a), the plug for wiring ducts (hereinafter, simply referred to as "plug") P of this embodiment includes: a contact element 2 that contacts the conductor 101 of the wiring duct 100 and conducts with the core wire of the power supply cable 150; The current sensor (current transformer) 4 detects the current flowing from the contact element 2 through the power supply cable 150; and the frame body 1 accommodates the contact element 2 and the current sensor 4 inside. in the figure 1 In (a), the plug P to which only one feeder cable 150 is connected is shown in figure.

[0061] The wiring duct 100 is also known previously as described in Pate...

Abstract

PROBLEM TO BE SOLVED: To detect easily an electric current supplied to an electric apparatus. SOLUTION: A plug for a wiring duct P includes: a contact piece 2 contacting with a conductor 101 of a wiring duct 100; a cable way 3 connecting a power supply cable 150 with the contact piece 2; a current sensor (current transformer) 4 detecting an electric current flowing from the contact piece 2 to the power supply cable 150; and a housing 1 housing the contact piece 2, the cable way 3, and the current sensor 4 therein and into which the power supply cable 150 is led. That is, the current sensor 4 is housed in the housing 1. Thus, unlike conventional electric apparatuses, a box 130 incorporating the current sensor (current transformer) does not need to be installed on a top surface of each server rack 120, and the electric current supplied to an electric apparatus 170 is easily detected.

Description

technical field [0001] The present invention relates to a plug for a wiring duct (duct). Background technique [0002] Conventionally, there have been provided plugs for wiring ducts detachably attached to the wiring duct (for example, refer to Patent Document 1 and Patent Document 2). Wiring ducts are installed in buildings such as factories or data centers that use multiple pieces of electrical equipment. For example, if Figure 7 As shown, power is supplied to a server rack (server rack) 120 from a conduit 100 installed on the ceiling of the data center via a conduit plug (hereinafter, simply referred to as a plug) 110 . In addition, the term "data center" is a general term for buildings used to install and operate Internet servers, data communication, fixed / portable / Internet Protocol (IP) telephones, and the like. Furthermore, the server rack 120 is, for example, a storage cabinet (rack) for storing a plurality of servers. [0003] In the illustrated example, in order...
