A design nameplate 11 is used as the closing plate, and an annular slit 14 is provided at a part of the design nameplate 11 facing the electric connector. A cutting tool insertion hole 15 is provided by enlarging a part of the width of the slit 14. The annular slit 14 is constituted of first slit through fourth slits 14a-14d, and coupling parts 17 for coupling the inner peripheral side and outer peripheral side of the annular slit 14 are formed between the first slit through fourth slits 14a-14d.

Description

  The present invention provides an electronic device that attaches a closing plate that closes an unconnected electrical connector and closes the electrical connector with the closing plate, thereby preventing damage to components inside the unit due to external static electricity during transportation or the like. It relates to equipment units.

The following three methods are adopted as a method of closing the electrical connector.
(1) A cap matched to the electrical connector is formed by resin molding or the like. Remove the cap when using the electrical connector.
(2) The top of the electrical connector is closed with a sheet metal or resin blocking plate. When using an electrical connector, remove the closing plate.
(3) A seal is affixed from the top of the electrical connector. When using an electrical connector, remove the seal.

As a method of closing the electric connector (2) above with a sheet metal or resin closing plate,
There are Patent Documents 1 and 2.

However, the conventional method for closing an electrical connector has the following problems.
(1) When a cap is used, the number of parts increases by using the cap as a separate part, resulting in an increase in cost. Since it is necessary to prepare the electrical connector according to the type and the number of poles, the types of parts increase. When parts are made of resin molded products, mold costs are incurred and initial costs are incurred.
(2) Even when a sheet metal or a resin-made closing plate is used, the number of parts increases by using the closing plate as a separate part, resulting in an increase in cost. Further, a screw or the like for attaching the closing plate is required. It is necessary to provide an attachment hole for attaching the blocking plate, and a space for the attachment hole is required. In addition, a space for attaching the closing plate around the electrical connector is required, which hinders downsizing of the electronic device unit.
(3) Even when a seal is used, the number of parts is increased by using the seal as a separate part, resulting in an increase in cost. There is a risk of peeling if the adhesiveness of the seal is poor. In order to ensure adhesion, it is necessary to make the size of the seal larger than the hole of the electrical connector. For this reason, a space is required around the electrical connector, which hinders downsizing of the electronic device unit.

  The present invention aims to reduce the number of parts by using a design nameplate in which an identifier such as a connector application or the name of an electronic device to be attached is used as the closing plate, and cuts and removes a part of the design nameplate. Thus, the blockage of the electrical connector can be released.

The present invention is an electronic device unit in which a closing plate for closing an unconnected electrical connector is attached, and the electrical connector is closed by the closing plate,
A cutting tool that uses a design nameplate as the closing plate, and has an annular slit having one or more connecting portions at the electrical connector facing portion of the design nameplate, and enlarges a part of the slit to cut the connecting portion. A cutting tool insertion hole for inserting the tip of the was provided.

  Since the design nameplate is used as the closure plate and the closure plate and the design nameplate are integrated, the conventional closure plate and the design nameplate are separately formed, for example, described in paragraphs [0015] to [0017] of Patent Document 2 The number of parts can be reduced as compared with the case where a sticker displaying an identifier is pasted on the closed plate.

  Also, if one end of the cutting tool is inserted into the cutting tool insertion hole and the other end of the cutting tool is pressed against the electronic device unit side, the cutting tool acts like an insulator and adds the design nameplate from the inside. The inner part of the slit from which the connecting part is cut can be taken out of the design nameplate.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an electronic device unit 1. The electronic device unit 1 includes a connector placement portion 2 below the one side surface 1a. The connector placement unit 2 is provided with a plurality of device connection connectors 3... 3 and electrical connectors 4 for connecting various devices. A design nameplate 11 that covers the device connector 3... 3 and the electrical connector 4 is attached to the front surface of the connector placement portion 2.

  As shown in FIG. 2, the design nameplate 11 has through holes 12... 12 formed at positions facing the device connection connectors 3... 3, respectively. The identifiers 13... 13 for displaying the usage of the device connection connectors 3... 3 and the names of devices to be attached are displayed.

  In addition, the design nameplate 11 includes an annular slit 14 at a position facing the electrical connector 4, and a cutting tool insertion hole 15 into which a distal end portion of a cutting tool 18 described later is inserted into a part of the slit 14. . An identifier 16 for displaying the electrical connector 4 is formed outside the annular slit 14.
