Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ground terminal mounting structure for a cathode ray tube.

[0002]

[Prior Art]

 Conventionally, for smoothing high voltage in a cathode ray tube, a condenser is formed inside and outside the cathode ray tube, and the outside of the condenser is integrally connected with an earth wire from the board that is attached to the rear part of the cathode ray tube by a ground wire and is guided to an external earth. ing. Or directly led to the main board.

In the conventional ground terminal mounting structure described above, for example, as shown in FIG. 3, for example, the ground wire 12 of the cathode ray tube 11 is generally connected to the cathode ray tube substrate 13, and the substrate 13 is provided with the earth terminal 14. Either by mounting and connecting the connector 16 provided at the end of the ground wire 15 to the ground terminal 14 or by connecting the end of the ground wire 15 to the rear side of the insertion hole 13a of the cathode ray tube substrate 13 as shown in FIG. The structure is such that after passing through the side, it is fixed to the copper foil of the cathode ray tube substrate 13 by soldering or the like.

[Problems to be solved by the device]

 However, in the above-mentioned conventional ground terminal mounting structure, it is necessary to mount the ground terminal on the cathode-ray tube board and pass the end of the ground wire through the back side of the board for soldering. Since parts such as connectors attached to the parts are required, the work of assembling these parts is troublesome, and the work for soldering the ground wire is troublesome, and there is a problem in reliability.

The object of the present invention is to solve the above-mentioned conventional problems. By providing a ground terminal in a part of the socket mounted on the cathode ray tube, the ground terminal attached to the cathode ray tube base plate can be reduced. In order to obtain a ground tube ground terminal mounting structure that simplifies the work of mounting the ground terminal.

[Means for Solving the Problems]

 In order to achieve such an object, the structure for mounting the ground terminal of the cathode ray tube according to the present invention is a socket body that is attached to the cathode ray tube substrate and attached to the cathode ray tube. It is characterized by being assembled with terminals.

[0007]

[Action]

 Based on such a configuration, according to the present invention, since the ground terminal is provided in a part of the socket attached to the cathode ray tube, the ground terminal attached to the cathode ray tube substrate can be reduced. The work can be simplified and the cost can be reduced.

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a socket showing a ground terminal mounting structure of a cathode ray tube according to the present invention, FIG. 2 is a perspective view of a focus gap ground metal fitting to which a ground terminal is attached, 1 is a cathode ray tube, 2 is a cathode ray tube substrate, Denoted at 3 are sockets attached to the cathode ray tube substrate 2 and attached to the cathode ray tube 1.

In the socket 3, a body 4 made of an insulator is provided with various terminal groups 5 and a focus gap ground metal fitting 6 which is discharged when a high voltage is applied to the cathode ray tube 1 to flow to an external earth.

The body 4 of the socket 3 is integrally assembled with a ground terminal 7 in which a part of the focus gap ground metal fitting 6 is modified. The shape and take-out position of the ground terminal 7 are arbitrary and are set so as not to interfere with the cathode ray tube substrate 2 to which the socket 3 is attached.

Therefore, in the embodiment of the present invention having the above-described structure, the number of ground terminals attached to the CRT substrate can be reduced by a simple structure in which a ground terminal is provided in a part of the socket attached to the CRT. .
