[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anode cap terminal for electrically and mechanically connecting to an anode of a cathode ray tube (CRT) of a television receiver, for example.

[0002]

2. Description of the Related Art An anode cap of this type is, for example, a coil spring or an anode engaging terminal composed of a pair of opposed leaf springs, and a cable for holding a high-voltage cable and connecting it to the core wire (often by soldering). It is generally composed of a connecting portion and an insulating cover covering the connecting portion. Then, the high-voltage cable is connected to the cable connection portion of the terminal body after the terminal body of the anode cap is formed.

[0003]

However, such an anode cap is not stable in the engagement with the anode (forming the recessed portion), and is not easy to remove after the engagement, and further the cable cannot be removed. There was a problem that it took time to connect.

[0004]

In order to solve the above problems, the terminal for a CRT anode cap of the present invention is a CRT.
A pair of terminal plates of substantially T-shape that are opposed to each other are formed on each of a pair of terminal portions that lock with the anode of the cable, and a cable grip portion for crimping the insulation coating of the cable and a core wire connection for connecting to the core wire of the cable. The parts are connected in a bridge shape.

[0005]

[Operation] The terminal of the present invention, before assembling the terminal body,
A pair of terminal plates formed on each of the terminal parts by connecting the cable insulation part and the core wire of the cable to the cable gripping part and the core wire connecting part, which are connected to each other, and after assembling the terminals, put the rubber caps on. To the anode of the CRT.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show a state before assembly of a terminal body according to the present invention. A plurality of terminal bodies are connected to the carrier, one of which is illustrated in the drawing. When using, separate each terminal body from the carrier. As shown in FIG. 3 and subsequent figures, the separated terminal body is formed by folding a cable connecting portion described later into a bridge shape, and both ends of the terminal body are locked to each other.

In the figure, the terminal body is a shield substrate 10.
A pair of terminal portions 30, a pair of support plates 20 and 20 extending from the shielding substrate to support the terminal portions, and a cable connecting portion 40. Each of the support plates extends downward from one side of the shield substrate so as to face each other. The terminal portions project from one of the supporting plates toward the opposing supporting plates. The cable connection portion is formed on the side of the shield substrate opposite to the support plate.

Each of the terminal portions has a pair of substantially T-shaped terminal plates 31, 31 facing each other. Each of the terminal boards has a locking piece 32 protruding in a direction opposite to the shield board. The locking piece is formed in a hook shape for locking with the anode of the CRT. The cable connecting portion 40 is composed of a cable gripping portion 41 for crimping an insulating coating of the cable, and a core wire connecting portion 42 which is connected to the cable connecting portion and connected to the core wire of the cable. Such a cable connecting portion is formed as a bridge between two opposing sides of the shielding plate.

In the illustrated embodiment, each of the terminal portions 30, 30 is formed as a box-shaped terminal having a rectangular cross section. The terminal portion is also directed toward the terminal board 21 extending downward from each of the support plates, the T-shaped terminal boards 31 and 31 protruding from both ends of the terminal board, and the other terminal portion. It is composed of a pair of half side plates 33, 33 protruding from the sides of the terminal plate in the direction of the opposing terminal plate.

The terminal portions 30, 30 protruding from the support plate are constructed so as to face each other with a gap therebetween. For this reason, the pair of terminal portions are flexible so that they can move closer to and further away from the support plate as a fulcrum.

In actual use, the pair of support plates are sandwiched by fingers, the two terminal portions are brought close to each other, and then the terminal portions are inserted into the anode electrode of the CRT. Even when the terminal portion is removed from the anode electrode, both support plates may be similarly sandwiched by fingers.

In addition, the substantially T-shaped terminal plates 31, 31 are provided with stop pieces 34, 34 on the side opposite to the engaging pieces 32, 32. Therefore, both terminal portions will not be bent more than necessary.

Next, the cable connecting portion 40 extends from one side of the shield substrate facing each other, and its tip is connected to the other side of the shield substrate. As a connecting means, for example, one tip portion is inserted into a slit provided in the other, and the tip portion penetrating the slit is bent.

[0014]

The terminal portion of the terminal for the CRT anode cap according to the present invention is box-shaped, so that it is more flexible when attached to the CRT anode electrode (recessed fitting portion) than the plate-shaped terminal portion. Incorrectly, they are correctly opposed to the anode electrode, and both are locked extremely stably and reliably.

In the cable connecting portion of the terminal of the present application, the cable gripping portion and the core wire connecting portion are integrally connected to each other, and unlike the case where the cable gripping portion and the core wire connecting portion are formed separately from each other, Before assembling the terminal body, connect the insulation coating of the cable and the core wire of the cable to the cable gripping part and the core wire connecting part respectively, because the positional relationship (the distance is constant) does not change before and after assembling the terminal body. You can Moreover, since the present invention does not require soldering work, the work of connecting the cable and the terminal is simplified.

Since the distance between the cable gripping portion and the core wire connecting portion is fixed, the positional relationship between the two is also fixed when the cable is connected. Therefore, as in the conventional example in which both are formed separately. There is a variation between the two, and there is no need for complicated work such as adjusting the length of the core wire to compensate for the variation.

Next, since the stop piece is projected on the substantially T-shaped terminal plate of the terminal portion, when the terminal of the present application is locked to the anode electrode, even if the terminal plate is sandwiched and bent inward. ,
Due to the action of the stop piece, it is not bent more than necessary.

As can be seen from the illustrated embodiment, the anode cap terminal of the present invention has a large X-ray attenuation effect because the shielding substrate can cover the entire anode electrode of the CRT. Further, in comparison with the conventional structure in which the cable gripping portion projects outward from the terminal body, in the present invention,
The cable connecting portion is comfortably housed in the insulating cover without digging into the insulating cover that covers the terminals, so that a sufficient insulating distance can be secured.
