The present invention relates to a wire fixing device of the main circuit board. More specifically, the assembly of the case is simplified by forming a wire connected to the magnetization elimination coil when assembling the case of the monitor. The present invention relates to a wire fixing device of a main circuit board which can be prevented.

In general, a computer used in an OA device or an information and communication field includes a main body for storing data, a keyboard for modifying and utilizing the data, and a monitor that can be displayed on a screen. (CRT) and electronic components are mounted, and the main circuit board on which the circuit pattern is formed is fixedly installed to perform each function.

1 and 2 illustrate a conventional main circuit board and a chassis frame for fixing the main circuit board, and a rear end of the main circuit board 10 is connected to a magnetization erasing coil (not shown). On the main circuit board 10, a power switch 12 for applying a current is provided, and the front end portion of the main circuit board 10 is turned on and off by applying pressure from the outside. A knob 13 to be provided is provided.

Meanwhile, a chassis frame 20 is installed in a monitor case (not shown) to fix the main circuit board 10. The chassis frame 20 has a step shape in the longitudinal direction and a c-shape in front of both side walls. The bent part 21 bent by this is formed, and the latching step 21a is processed below this bent part.

In addition, a guide rail 22 into which the main circuit board 10 is inserted is fitted into the engaging step 21a, and the guide rail 22 is inserted into and supported by the insertion groove 22a and the engaging step 21a. The engaging pieces 23 are formed in both side ends as much as possible.

When the conventional main circuit board configured as described above is fixed to the chassis frame, the guide piece 22 of the guide rail 22 is caught on the rear side wall by the engaging step 21a formed on the chassis frame 20. The rail 22 is fixed, and the main circuit board 10 is pushed and fixed in the longitudinal direction while both sides of the front end portion of the main circuit board 10 are inserted into the insertion grooves 22a of the guide rail 22.

When the knob 13 provided on the same axis of the power switch 12 is pressed in the state in which the main circuit board 10 is assembled, one end of the knob 13 comes into contact with the operation shaft 14, and the operation shaft ( 14) The power switch 12 is operated by touching the input unit of the power switch 12 while sliding.

In addition, as the power switch 12 is operated, various electronic components installed on the power switch 12 and the main circuit board 10 are operated to achieve a predetermined purpose.

However, when the main circuit board configured as described above is fixed to the chassis frame and mounted in the case, as shown in FIG. 2, since the wire connected to the magnetization erasing coil flows freely, the wire between the case is assembled during the case assembly of the monitor. As a result, the assembly work becomes cumbersome, as well as the main circuit board on which the electronic components are mounted and the wire connected to the magnetization scavenging coil are in contact with the power supply noise, thereby reducing the reliability of the product.

Therefore, this invention is to solve the above problems, and the object of this invention is to mold the wire connected to the magnetization erase coil to the mold frame in which the main circuit board is broken, thereby reducing the time when assembling the case of the monitor The present invention provides a wire fixing device for a main circuit board which can reduce a process and prevent power supply noise caused by contact between a wire connected to a main circuit board and a magnetization erase coil to improve product reliability.

A feature of the wire fixing device of the main circuit board according to the present invention for achieving the above object is, in the monitor case, the chassis frame is installed, the main circuit board is equipped with electronic components fixed to the chassis frame, A mold frame to which the main circuit board is fixed is provided, and a snap is formed on the mold frame so as to easily shape the wire connected to the magnetization erase coil.

Hereinafter, a preferred embodiment of the wire fixing device of the main circuit board according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a view illustrating a wire fixing device of a main circuit board according to the present invention, and includes a mold frame 40 for easily fixing the main circuit board 10, and corresponds to both sides of the mold frame 40. A first protrusion 41 is formed, and a second protrusion 42 is formed on the first protrusion 41 so as to form a predetermined gap.

In addition, the protrusion 43 is protruded in a horizontal direction to prevent bending of the main circuit board 10 due to the load of the electronic component on the bottom of the mold frame 40, the magnetization on the upper surface of one side of the mold frame 40 To form the wire 11 connected to the erasing coil to form a snap 44 of the L-shaped fixing means is integrally formed, or the snap 44 is formed on both sides of the mold frame 40 protruding.

The snaps 44 are protruded at equal intervals so that the surfaces facing the upper surface of the mold frame 40 are alternately protruded from each other, or the wires 11 connected to the magnetization erase coils are staggered and shaped.
