Description

[Detailed Description of the Invention] The present invention relates to a terminal plate fixing device for connecting lead wires of a deflection yoke device.

Generally, a deflection yoke device consists of a pair of saddle-shaped horizontal coils attached to the inner circumferential surface of a conical coil separator made of synthetic resin, etc., and a toroidal-type vertical coil attached to the outer circumferential surface.
A terminal board device for connecting lead wires is provided to connect each coil to an external circuit.

This terminal plate is generally fixed to the rear enlarged portion of the coil separator.

One such means is a structure shown in FIGS. 1 and 2, for example.

That is, the deflection yoke device 1 includes a saddle-shaped horizontal coil (not shown) attached to the inner peripheral surface of a conical coil separator consisting of a front enlarged part 2 and a conical cylinder part (not shown) and a rear enlarged part 3, and A toroidal vertical coil is attached to the surface.

The rear enlarged portion 3 of the coil separator includes a first pair of tongues 4□, 4□′ that face each other at a constant interval and have hook-shaped tips; this first pair of tongues 4□; 4,'
A second pair of tongue pieces 42, 4□', which are formed in the same manner as above and are disposed opposite to the first tongue pieces 4a, 4□', are formed so as to protrude from each other.

These tongues have elasticity on opposite sides of the circumference of each pair of tongues.

(In the direction of arrow A in the figure) 5 is a terminal board, which has a plurality of relay terminal fittings 6, and square through holes 7, 7' near both ends.
is formed.

That is, by elastically press-fitting the pair of tongue pieces 4□, 41' and 42.42' protruding from the coil separator into the through holes 7 and 7' of the terminal plate 5,
As shown in the sectional view of FIG. 3, the terminal plate 5 is fixed to the coil separator.

The lead wire of the deflection coil is fixed to the terminal fitting 6 of the terminal plate 5 by soldering.

However, according to such a fixing method that utilizes the elastic force of a pair of opposing tongues in opposing directions, for example, when adjusting the deflection coil, transporting it, or installing it into a television receiver, the problem shown in FIG. Terminal board 5 in the direction of arrow B shown in
When the terminal board is twisted, the force causes the tongue to bend and the terminal board has the disadvantage of being easily pulled out.

This may lead to breakage of the lead wire.

The present invention provides a deflection yoke terminal plate fixing device that has a simple structure, secures the fixation, and has an excellent terminal plate structure in such a method for attaching a terminal plate.

Embodiments of the present invention will be described in detail below with reference to FIGS. 5 to 7.

In the present invention, the coil separator of the deflection yoke and the tongue protruding from the coil separator are the same as those shown in FIG. 1, so a detailed explanation of these parts will be omitted.

That is, FIG. 5 shows a terminal board main body 10 made of a thermoplastic resin such as polypropylene, and a terminal board 12 having a relay terminal fitting 11 on one side is formed.

Near both ends of this terminal plate 12 are square through holes 13, 13'.
is formed.

The through holes 13 and 13' are open to both ends of the terminal plate 12 through cutouts 14 and 14' having a diameter smaller than that of the through holes.

At the open end of this notch 14, 14' there are hooks 15, 15.
' is formed.

Next, a cover portion 17 having approximately the same area as the terminal plate 12 is integrally formed from the terminal plate 12 via a hinge portion 16.16'.

From the middle of both ends of this cover part 17 is a hinge part 19.19.
T-shaped arm portions 18, 18' having substantially the same width as the notches 14 and 14' are formed to protrude through the notches 14 and 14'.

Projections 20, 20' project from the arms 18, 18'.

The terminal board main body 10 configured in this manner includes a pair of first and second tongue pieces 4 of the coil separator. ．． 4. ', 4□
.

The through holes 13, 13' are elastically fitted into the holes 42'.

After the lead wire of the deflection coil is clamped and soldered to the relay terminal fitting 11, the cover 7 part 17 is attached to the terminal board via the hinge part 16. Fold it to cover 12.

Then, the T-shaped arms 18, 18' of the cover part 17 are bent through the hinge parts 19°19', and the arm parts 18, 18' are bent.
into the notch 14°14' against the hooks 15, 15'.

As a result, the protrusions 20, 20' of the arms 18, 18' are connected to the pair of tongue pieces 4□, 4,' and 4□ in the through holes 13, 13'.
, 4□'.

The arm parts 18, 18' are locked by the hook parts 15, 15' of the notch 14, 14', and the T-shaped tips of the arm parts 18, 18', so that the cover part 17 is not pulled out. can completely cover the wiring portion of the terminal board 12.

Since the protrusions 20 and 20' of the arm portions 18 and 18' are fitted between the pair of tongue pieces of the coil spacer after the terminal plate is fitted, for example, as shown in FIG. Arrow B
Even if a force in a torsional direction is applied, the pair of opposing tongues will not bend, and therefore the terminal plate will not come off.

As described above, according to the present invention, the integral structure of the terminal board and part of the cover completely covers the live terminal part of the deflection yoke to prevent the risk of electric shock, and the structure in which the cover is attached prevents the terminal board from being exposed to electric shock. It is possible to obtain an extremely functional and excellent terminal board fixing device that can completely prevent the terminal board from coming off.

Furthermore, by integrating the cover and the terminal board, it not only simplifies the production management of individual products but also contributes to lower prices.
