The present invention relates to a neck portion fixing device of the deflection yoke, and more particularly, by preventing the neck portion of the deflection yoke from flowing upward and downward, the deflection yoke is installed on the neck portion of the CRT, and the screen characteristic is changed while flowing in all directions. It relates to a neck fixing device of a deflection yoke so that its neck is not twisted when adjusted.

In general, deflection yoke is installed in the neck portion of the CRT, and is composed of a combination of horizontal deflection coils 2 and vertical deflection coils 3 as shown in FIG. 1 and a pair of coils separated from each other. After the horizontal deflection coil 2 is installed on the inner circumferential surface of the separator 1, a pair of coil separators 1 are coupled to each other by a locking jaw 5b and a locking groove 5a formed in the neck portion 5. In addition, a vertical deflection coil 3 is installed on the outer circumferential surface thereof in a coupled state, and a pair of ferrite cores 4 are provided on the outer circumferential surface of the coil separator 1 so as to reinforce the magnetic field of the vertical deflection coil 3. .

The deflection yoke configured as described above deflects the electron beam emitted from the electron gun of the CRT in the left, right, and up and down directions to collide with the RGB formed on the fluorescent surface of the CRT. However, conventionally, the neck portion 5 of the deflection yoke is fixedly installed in the neck portion of the CRT, and then the neck portion 5 is twisted in the process of flowing in all directions to adjust the screen characteristics thereof. There is this. That is, the neck portion 5 has a disadvantage in that the coupling force is strong while the torsion stress is weak because the locking jaw 5b and the locking groove 5a are simply coupled.

The present invention was devised to solve the conventional problems, and an object of the present invention is to prevent the neck portion from being twisted by forming support means for suppressing the flow in the up and down directions in the neck portions corresponding to the coil separators separated from each other. A neck fixing device of a deflection yoke is provided.

In order to achieve the above object, the present invention provides a horizontal deflection coil for horizontally deflecting an electron beam on a pair of coil separator inner circumferential surfaces separated from each other, and a vertical deflection coil for vertically deflecting an electron beam on an outer circumferential surface thereof, respectively. The engaging jaw and the engaging groove which are coupled to each other are formed at the end of the neck of the coil separator, respectively, and the supporting means is provided at the rear end of each neck to suppress the flow in the up and down directions.

Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings in detail as follows.

2 is an exploded perspective view of the neck portion of the present invention, and FIG. 3 is a cross-sectional view of the present invention deflection yoke. Horizontal deflection coils 11 for horizontally deflecting the electron beam are provided on the inner circumferential surface of the pair of coil separators 10 separated from each other, and vertical deflection coils 12 for deflecting the electron beam in the vertical direction on the outer circumferential surface of the coil separator 10. Is installed. In addition, the ferracoite core 13 is provided on the outer circumferential surface of the coil separator 10 to reinforce the magnetic field of the vertical deflection coil 12.

In addition, the engaging jaw 15 and the engaging groove 16 are formed at the ends of the neck portion 14 corresponding to each other of the pair of coil separators 10 to be coupled to each other, and the upper and lower sides at the rear ends of the neck portions 14, respectively. Support means 17 for suppressing the flow in the direction is provided. The support means 17 prevents the neck portion 14 coupled to each other from twisting, and the neck portion 14 is provided with a protrusion 18 on one side of the neck portion 14, and the protrusion 18 is fitted on the other neck portion 14 corresponding thereto. Each losing groove 19 is provided. These protrusions 18 and the grooves 19 are alternately formed in the diagonal direction of the neck portion 14 corresponding to each other.

According to the present invention configured as described above, horizontal deflection coils 11 are respectively installed on inner circumferential surfaces of the coil separator 10 separated from each other, and then they are stacked and coupled to each other. In addition, the engaging jaw 15 formed at the front end of each neck portion 14 in the process of being coupled is fitted into the corresponding engaging groove 16 does not come back. Therefore, the pair of coil separators 10 are not separated in the coupling direction. In addition, the protrusions 18 alternately formed in the process of coupling each neck 14 are fitted in the groove 19. When they are fitted together, the assembled neck portion 14 does not flow in the upward and downward directions and thus has a torsion stress.

In addition, a vertical deflection coil 12 is installed on the outer circumferential surface of the coil separator 10 coupled to each other, and a ferrite core 13 for reinforcing its magnetic field is provided. The deflection yoke of the present invention, which is assembled as described above, flows in all directions for screen adjustment while installed in the neck portion of the CRT. In addition, the neck portion 14 flows in the up and down direction in the flow process, the screen adjustment is made precisely because the flow is suppressed by the projections 18 and the groove (19).

As described above, according to the present invention, when the engaging jaw and the engaging groove are respectively formed in the neck portions of the coil separators separated from each other, they are not separated in the coupling direction. In addition, protrusions and grooves are provided at the rear of each neck to prevent flow in the up and down directions so that the necks are not twisted when they are coupled to each other. Therefore, when the deflection yoke is installed in the CRT and flows in all directions for the screen adjustment, the neck portion of the deflection yoke flows in the up and down direction, and thus the screen adjustment is accurately performed.
