Description

VRT's Power Supply Fixed Structure

The present invention is a power supply fixing structure of a video cassette tape recorder (hereinafter referred to as' V'al), and more specifically, a power supply which converts power supplied to a V'al to a prescribed voltage and at the same time stabilizes the voltage. It relates to the improvement of the fixing structure.

In general, V-Cal moves relatively low speed relative to the head drum assembly while the magnetic tape is in contact with the periphery of the high speed rotating head drum assembly. An apparatus for reading or recording video signals recorded on magnetic tape.

The head drum assembly is mainly installed on the deck assembly having a predetermined traveling system to rotate by the driving force of the capstan motor, the deck assembly is installed in the main chassis forming a predetermined space. In addition, the V-Cal is fixed to various electronic components for supplying electricity to the various electrical components provided to the deck assembly or processing signals input or output to the video head, the main PC and the main to allow the electricity between these electronic components It includes a front PCB provided with various control switches actuated by the operating force of a knob operated by actual users at the front of the chassis.

The main PC ratio and the front PC ratio are mainly made of a synthetic resin material and are formed with a complex pattern on the surface to process various electrical signals, and have to withstand external shocks sufficiently to provide good signal transmission and stable support for a large number of electronic components. It must have a structurally stable fixed structure.

Here, referring to FIG. 1, the overall configuration of the conventional VRC is mainly made of a synthetic resin material, and is provided with a main chassis 10 of a cube having an upper portion open and having a predetermined installation space therein. The main PC ratio 20 is assembled to the inner lower part of the main chassis 10 by screws, and the deck assembly 30 having the head drum assembly thereon is assembled.

In addition, the upper cover 40 and the lower cover 50 are respectively fixed to the upper and lower surfaces of the main chassis 10 by screws. The front panel 60, which is provided with various knobs, is fixed to the front of the main chassis 10.

Electronic components such as a transformer 22 and a power supply 24 to which an external power source is connected are fixed to the main PC 20. The power supply 24 acts together with the transformer and changes the supply voltage to the required voltage required by V-Cal and stabilizes the voltage.

As shown in FIG. 2 and FIG. 3, the power supply 24 has a plurality of leads 24a protruding downwardly by being inserted into the fixing holes 22 formed in the main PC ratio 20 and soldered thereto. The upper surface is formed with a plurality of heat dissipation holes 22 for dissipating heat inside. In addition, a shock absorbing member 26 is provided at the top of the power supply 24. The shock absorbing member 26 is made of rubber having a relatively good elastic force, and after assembly is completed, the upper surface is pressed by the upper cover 40 to protect the power supply 24 when the impact is applied from the outside and at the same time the power supply. The 24 is prevented from being separated from the main PC ratio 20.

However, the conventional power supply fixing structure as described above requires an expensive shock absorbing member 26 that restricts the detachment of the power supply 24 during the drop test, which requires a lot of manufacturing cost, and further, the power supply 24 There was a problem that could not effectively limit the exit.

In other words, V-Cal performs various drop tests such as plane drop test, side drop test and edge drop test to maintain the reliability of the product. However, in the conventional structure, the lead 24a of the power supply 24 is directly inserted into the fixing hole 22 of the main PC ratio 20 to fix the lead 24a as well as to fix the lead 24a before soldering. Since it is possible to flow in the hole 22, it is assembled in a structurally weak form. Accordingly, the drop of the power supply 24 of the relatively heavy weight during the drop test, so that the damage to the periphery of the fixing hole 22 of the main PC ratio 20 as well as the problem that the copper foil formed in the main PC ratio 20 floats Will have This problem occurs intensively during the plane test, and in order to prevent the expensive buffer member 26 is inserted between the power supply 24 and the upper cover 40, the manufacturing cost is increased as well as the buffer member ( The installation of 26) alone could not effectively prevent the above problems.

The present invention has been devised to solve the conventional problems as described above, the purpose of which does not require an expensive buffer member, to maintain a good bond strength to minimize the risk of departure during the drop test It is to provide the power supply fixing structure of V-CAL.
