Description

  The present invention relates to an electric device to which different types of connector elements can be attached.

  As a conventional electric device, for example, as shown in Patent Document 1 and Patent Document 2, an AC plug provided in the main body of the electric device can be fitted with a conversion plug suitable for a foreign outlet so that it can be adapted to an outlet in each country. What to do is considered.

  The conversion plug is formed with a plug insertion portion into which the plug blade of the AC plug in a state of protruding outward from the electric device body is inserted, and the plug blade of the AC plug is inserted into the plug insertion portion. Thus, the conversion plug is configured to be attached to the electric device body.

  However, since the plug plug inserts the plug blade of the AC plug, it is necessary to make the thickness more than the length of the plug blade of the AC plug, and the size of the conversion plug is limited by the length of the plug blade of the AC plug. There is a problem that it ends up. In addition, when the conversion plug is used, the AC plug provided in the electric device main body becomes an unnecessary part.

  Furthermore, it is necessary to provide the conversion plug with a contact terminal for making electrical contact with the AC plug, and in order to make electrical contact between the contact terminal and the plug pin of the conversion plug, Since it is necessary to connect with solder or the like and the structure becomes complicated, the manufacturing cost and the component cost increase.

  Therefore, in order to solve the above-mentioned problems, the present invention has been made by taking away from the idea of attaching the conversion plug to the AC plug provided in the electric device main body without removing the AC plug from the electric device main body. A configuration in which a conversion plug (second connector element) of a type different from that of the first connector element can be directly attached to the electric equipment body in a state where the AC plug (first connector element) provided in the electric equipment body is not attached. Thus, the main problem is to make the electric device main body common and to reduce extra parts such as connection terminals, lead wires, and solder for contacting the AC plug and the conversion plug.

  That is, an electrical device according to the present invention includes an electrical device main body having a first connector element mounting portion to which a first connector element is mounted and a circuit board that can be electrically connected to a contact terminal of the first connector element. In a device, the second connector element attached to the electric device main body is formed with a second connector element different in type from the first connector element in a state where the first connector element is not attached to the electric device main body. The contact terminal of the second connector element is electrically connected to the circuit board.

If it is such an electric equipment, the 2nd connector element is attached to the 2nd connector element attachment part in the state where the 1st connector element is not attached, and the contact terminal of the 2nd connector element concerned Since it is electrically connected to the receiving terminal of the circuit board, the electric device main body can be shared by different types of connector elements. Thereby, component parts, such as a case and a circuit board which comprise an electric equipment main body, can be shared. Therefore, the manufacturing cost can be reduced.
Further, since the conversion plug that is the second connector element is not inserted into the rotary plug that is the first connector element as in the prior art, the first connector element is not necessary when manufacturing an electrical device having the second connector element. It becomes. Accordingly, the second connector element can be thinned without being restricted by the first connector element, and it is not necessary to provide an intermediate terminal for electrically connecting the second connector element to the first connector element. Manufacturing costs can be reduced.

It is desirable that the second connector element is externally attached to the electric device main body.
In this case, it is not necessary to incorporate a connector element when assembling the electric device main body, and it is only necessary to attach the second connector element after assembling the electric device main body, so that the assembling work can be facilitated.

The first connector element attachment portion may be an opening for exposing the first connector element to the outside when the first connector element is attached to the electric device body.
If it is this, since the electric equipment main body provided with the opening part which exposes the 1st connector element to the exterior can be diverted when manufacturing the electric equipment which has the 2nd connector element, manufacturing cost can be reduced.

The second connector element mounting portion is constituted by the opening, the second connector element has an insertion portion to be inserted into the opening, and the insertion portion is inserted into the opening. Accordingly, it is preferable that the second connector element is attached to the electric device main body.
If this is the case, the opening for exposing the first connector element to the outside and the second connector element mounting portion are common, and there is no need to form a dedicated mounting portion for mounting the second connector element. The configuration of the electric device body can be simplified.

The first connector element is rotatably mounted between a state accommodated in the electric device main body and a state protruding from the electric device main body, and the opening rotates the first connector element. It is desirable to be for moving.
If it is this, an electric equipment main body can be shared between the electric equipment whose 1st connector element is a rotary plug. In particular, the second connector element can be attached by taking advantage of the main body configuration unique to the electric device having the rotary plug.

A fixing mechanism for fixing the second connector element to the electric device main body, and the fixing mechanism includes an engaging portion provided on one of the electric device main body or the second connector element; It is desirable that the device main body or the second connector element is provided on the other side of the device main body or an engaged portion that engages with the engaging portion.
In this case, when the second connector element is screwed to the main body of the electric device, the second connector element is fixed to the main body of the electric device by the fixing mechanism, so that the screw fixing work can be facilitated.

It is preferable that the second connector element is attached to the electric device main body by rotating the second connector element in contact with the electric device main body.
If it is this, it can fix only by making a part of 2nd connector element contact and rotate to an electric equipment main body, and the attachment operation | work of a 2nd connector element can be made easy.

It is desirable that the contact terminal of the second connector element is in contact with a receiving terminal that is provided on the circuit board and contacts the contact terminal of the first connector element.
In this case, in the circuit board, it is not necessary to provide a receiving terminal for each type of connector element, and the receiving terminal can be shared by different types of connector elements. Thereby, the circuit configuration of the circuit board can be simplified, the number of parts can be reduced, and the cost can be reduced.

The position where the receiving terminal and the contact terminal of the second connector element are in contact with each other is preferably different from the position where the receiving terminal and the contact terminal of the first connector element are in contact with each other.
In this case, the position of the contact terminal of the second connector element can be set without being restricted by the position of the contact terminal of the first connector element, and the degree of freedom in design can be expanded.

  According to the present invention configured as described above, the connector element such as the conversion plug is attached to the electric device main body in a state where the connector element such as the AC plug is not attached, and the contact terminal of the connector element such as the conversion plug is provided. Since it is electrically connected to the receiving terminal of the circuit board, the electric device main body can be shared by different types of connector elements.
