The present invention relates to a front panel fixing device mounted on the front face of a video tape recorder (FRONT COVER).

In general, the front cover of the video tape recorder is equipped with various adjustment button knobs, digitrons, and remote control receivers, and the front panel can cover the installation space of various adjustment button knobs while making the exterior of the VTR beautiful. The panel and the front window are fixedly installed and the PCB board (timer PCB) is fixedly installed inside the front panel. Conventionally, as shown in FIG. 5, various adjustment knobs (B), a cassette insertion hole (C), and a digital display are generally installed. Front window (T) fixed to the front cover (A) of the VTR in which the Tron (D) and the remote control receiver (E) are installed, and separately formed in the digitron (D) portion of the front cover (A) and the remote control receiver (E). In addition to the attachment of W) with an adhesive, the PCB board P fixed inside the front panel F has an insertion groove H around the front cover A. Because be formed by inserting a P.C.B substrate (P) has the spacing of the front cover (A) with P.C.B substrate (P) is very narrow.

Therefore, in the conventional method, the front panel and the front window are separately manufactured and attached and fixed as fusion or adhesive, respectively, so that the assembly and fixing work is complicated and the work efficiency is reduced, and the front panel and the front window are separated. Since it is fixed and attached, the appearance of the front part of the VTR is not beautiful and the quality of the product is reduced. Also, the clearance between the PCB board and the front cover fixedly fixed to the front cover becomes very narrow. The work was very inconvenient, and it was not very economical due to the breakage phenomenon during the initial separation of the PCB because it did not form many holes in the production of the PCB itself. If you are not careful, To force the adhesive to bury a product made abuse thus lowering the operating efficiency and reduced productivity, and becomes a factor of increasing the manufacturing cost.

The object of the present invention is to compensate for the above-mentioned conventional problems to form a front panel and the front window fixed to the front cover of the front cover of the VTR as a single body, to form a tension engaging piece integrally protruding the front panel around the inner side of the front panel The PCB board fixed to the inside of the front panel can also be easily and easily fixed to the cover, and the front cover and the PCB board are separated by a predetermined distance (L) by fixing the PCB and the locking tension protrusion protruding from the front cover. As to provide a front cover fixing device, when the present invention will be described in detail by the accompanying drawings as follows.

In the construction of the present invention, as shown in FIG. 1, a plurality of catching grooves are provided around the front cover 1 of the VTR provided with a cassette insertion hole 2, a remote control receiver 3, a digitron insertion hole 4, and the like. 5) is formed, the protruding toward the front surface is formed with a plurality of locking projections (6) for fixing the PCB substrate (P) is formed on the lower side and the engaging tension projection (7) is formed on the upper side, the front cover (1) A plurality of insertion grooves 8 are formed at the periphery of the PCB board P installed at the front side, and a plurality of fixing protrusions 10 are disposed at the front panel 9 which is covered and fixed to the front of the PCB board P. They are formed to protrude around the front cover 1 and the front panel 7 and the front panel 7 to cover the digitron 4 and the remote control receiver 3 installed on the PCB board (P) is formed integrally.

If described in detail the effect of the assembly installation of the present invention as follows.

When the locking projection 6 protruding from the front of the front cover 1 of the VTR and the locking tension projection 7 coincide with the insertion groove 8 formed around the PCB board P, the front cover 1 is pushed upward. The locking tension projection 7 is pushed and is fixed while maintaining the front cover (1) and the electrical separation (L) by holding the PCB substrate (P) while the tension operation. In this way, the PCB substrate P is first fixed to the front cover 1 front side, and then, as shown in FIG. 2, the fixing protrusion 10 protruding inside the front panel 9 has an insertion groove of the front cover 1. As shown in FIG. 3 (a) (b), the front cover 1 and the PCB substrate P are spaced apart by the tension force of the locking projection 7 as shown in FIG. In the state spaced apart by (L), the front panel 9 is firmly installed on the front. Therefore, the front panel can be fixed to the front cover by a process of forming the front panel and the front window integrally and inserting them at once without separately separating and attaching the separately manufactured front panel and the front window separately. The operation is very easy and simple, which reduces the manufacturing cost by improving the work efficiency and productivity, and is also installed at a certain distance (L) between the front cover and the PCB, so it is easy to organize the wiring connected to the back of the PCB. Since it is possible to assemble the PCB board easily and there is no shape on the front surface of the PCB board, it is possible to form a large number of machine holes, which prevents damage during the initial separation of the board. In addition, the front panel and front window As a result, it was possible to enhance the product while enhancing the front appearance of the VTR, and to eliminate the use of adhesives, which also reduces the consumption of raw materials because the productivity is improved due to the simplification of the work process and the product is not made defective by the adhesive. It is economical and reduces the manufacturing cost.

Claims (1)

In the fixing device of the front panel 9 provided on the front of the front cover 1 of the VTR, the front panel 9 is integrally formed with the front window, and the fixing projection 10 is formed around the inner surface of the front panel 9. The front panel 9, which is integral with the front window, is fixedly installed in the engaging groove 5 formed in the front cover 1, and the PCB substrate P is placed inside the front panel 9. The front panel (P) is spaced apart by a predetermined distance (L) by the tension force of the engaging tension projection (7) by fixing it to the latching projection (6) and the engaging tension projection (7) protruding from the (1). 9) The front panel fixing device of the VTR, which is fixedly installed on the inside.
