Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric device equipped with a power supply unit which can be taken in and out.

[0002]

2. Description of the Related Art In electrical equipment, a unit is composed of a circuit board which constitutes a control circuit for controlling the function of the equipment, and a power source section provided with parts such as a transformer and a capacitor for supplying electric power to the circuit board. Configured independently of the circuit board, these circuit board and power supply unit are housed inside the equipment case, and the power supply unit can be put in and taken out of the equipment case for convenient maintenance and replacement of parts. There is something I did.

In such an electric device, the distance between the power supply unit and the circuit board differs when the power supply unit is housed inside the device case and when the power supply unit is taken out of the device case.

Therefore, the power supply unit and the circuit board are electrically connected by a connection cable having a length that allows a large number of single wires to be bundled and the power supply unit can be taken out from the equipment case.

That is, when the power supply unit is housed inside the equipment case, the connection cable is folded inside the equipment case because the distance between the power supply unit and the circuit board is short. Be accommodated.

When the power supply unit is taken out of the equipment case, the distance between the power supply unit and the circuit board becomes long, so that the connection cable is pulled out of the equipment case together with the power supply unit and deployed.

[0007]

However, the circuit board, which is housed and fixed in the equipment case, and the power supply unit, which is housed in the equipment case so as to be removable, can be taken out of the equipment case. In the configuration connected by a connection cable with a length that enables
There are the following problems.

That is, when the power supply unit is inserted and housed in the equipment case, the connection cable is pushed toward the inside of the equipment case by the power supply unit and is housed inside the equipment case in a disorderly and randomly bent state.

Here, the chaotically and randomly bent connection cable has many spaces, and the shape of the bent connection cable changes each time the power supply unit is inserted into the equipment case.

Therefore, the space inside the equipment case requires a large space portion to accommodate the connection cable which is disorderly and randomly bent, and as a result, the entire equipment case becomes large.

Further, the connection cable pushed into the equipment case in a chaotically and randomly bent state constitutes an electronic component attached to a circuit board and a power supply unit by being randomly and randomly bent. It may come into contact with parts, which may adversely affect the performance of electrical equipment.

Therefore, it is conceivable to provide the circuit board and the power supply unit with a cover for avoiding contact of the connection cable. However, in this case, the number of parts increases, which is uneconomical, and the configuration becomes complicated.

The present invention has been made based on the above circumstances, and avoids an increase in the size of the equipment case when the connection cable for connecting the circuit board and the power supply unit is housed inside the equipment case, and the connection cable is It is an object of the present invention to provide an electric device that can prevent contact with electric components of a circuit board and a power supply unit.

[0014]

In order to achieve the above object, an electric device according to the present invention is an electric device in which a circuit board is housed in a device case and a power supply unit is housed in and out of the device case. The board and the power supply unit are connected by a connection cable having a plurality of connection lines bundled and having flexibility and having a length that enables the power supply unit to be removed from the device case. Has one end connected to one end of the power supply unit, the other end connected to the other end of the circuit board, and the power supply unit further includes a connection cable support member along a direction connecting the one end and the other end. The support member is provided with a mounting portion that receives the connection cable on the lower side and the power supply unit that is inserted into the device case and contacts the circuit board. And having a said connecting cable upright portion erecting at the position serving as the power supply unit moving direction rearward with respect to when moving in the direction of.

[0015]

When the power supply unit is taken out from the inside of the equipment case, the connection cable is pulled out by the power supply unit and is pulled out to the outside of the equipment case while being detached from the supporting member provided in the power supply unit.

Therefore, the power supply unit can be pulled out to the outside of the equipment case.

When the power supply unit is inserted into the equipment case, as the power supply unit is inserted into the equipment case, the connection cable is provided on the power supply unit from one end to the other end thereof. Supported by.

That is, the connection cable is accommodated inside the equipment case while being supported linearly on the power supply unit side by the support member.

As described above, when the power supply unit is housed in the equipment case, the connection cable is forcibly and neatly housed in the equipment case.

Therefore, since it is not necessary to secure a large internal space in the equipment case as compared with the case where the connection cables are housed in a disorderly and disordered state, it is possible to prevent the equipment case from becoming large.

Further, when the power supply unit is housed in the equipment case, the connection cables are not housed in a disorderly and disordered state, and the circuit board and the parts of the power supply unit are not contacted.
