Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a card basket device for mounting a printed circuit board in electronic equipment or the like.

In the conventional card basket device of this type, as shown in FIGS. 1 to 3, a connector 5 is attached to an upper card guide 3 and a lower card guide 4 provided between side plates 1 and 2.
A printed circuit board 6 guided and supported by upper and lower card guides 3 and 4 is inserted into this connector 5.

In this conventional device, a stabilized power supply unit is provided outside the card basket device, and power is supplied from this power supply unit to the printed circuit board 5 via the connector 5 of the card basket device.

Further, the rectifying and smoothing section of the stabilizing blade source unit is provided outside the card basket device, and the constant voltage blind pupil (AVR) section is mounted as an AVR card inside the card basket device, side by side with other printed circuit boards 6. However, with this conventional method,
Care must be taken to separate wiring due to noise issues.

Furthermore, when an AVR card is mounted in a card basket device, it is necessary to reduce the thermal influence on other cards alongside the AVR card. Additionally, there are disadvantages in that the number of structural components increases, the heat dissipation fins of the power supply unit become larger, and the weight becomes heavier. This invention was made to solve the drawbacks of these conventional devices, and by using a stabilized power supply unit as a part of the component parts of the card basket device, the entire card basket device has a heat dissipation effect, and the power supply unit The idea is to reduce the weight by reducing the size of the heat dissipation fins, and to create a structure that is resistant to noise by using a busbar to connect the secondary side of the power supply unit, which carries a large amount of current, and the connector on the printed circuit board. be.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 8.

That is, in FIGS. 4 to 8, numerals 3 to 6 indicate the same or corresponding parts as those in FIGS. 1 to 3. 7 is a support that is attached to the upper and lower card guides 3 and 4 by screws 8 and serves as a side plate and also serves as a component of the stabilized power supply 9; 1; a cooling fin attached to the power supply unit 9;
11 is a fuse attached to the power supply unit 9, 12 is a primary terminal of the power supply unit 9, and 13 is a 2nd terminal of the power supply unit 9.
A secondary terminal 14 is a push bar connected to the secondary terminal 13 with a screw or the like and connected to the connector 5 by soldering.

With this configuration, power is supplied from the power supply unit 9 to the printed circuit board 6 via the busbar 14 and the connector 5.

In this case, the heat generated from the power supply unit 9 is radiated from the cooling fins 10, but at the same time, it is also radiated from the upper and lower card guides 3 and 4 via the support 7, so it is possible to make the heat radiating fins 10 smaller. can. In the card basket device, a power supply unit with cooling fins is directly attached to a support that also serves as the side plate of the upper and lower card guides to which connectors are attached. Since the heat generated in the power supply unit is directly connected to the power supply unit, it is dissipated not only from the cooling fins of the power supply unit, but also from the support and the upper and lower card guides, which improves the cooling effect of the card basket device. Not only is this significantly improved, but
Since the cooling fins of the power supply unit can be made smaller, this has an excellent effect of contributing to the miniaturization of not only the power supply unit but also the card basket device.
