The present invention relates to a mounting structure of a cabinet body and a front panel in a television receiver.

In a television receiver in which the cabinet body is made of a plate made of wood or the like, the front panel mounted so that the front portion of the CRT is directed toward the opening portion is fitted in such a manner as to be inserted into the front opening portion of the cabinet body. The mounting position of the front panel with respect to the cabinet body is regulated by mating the fitting recesses formed on the rear end face of the panel and the fixed block disposed on the inner side of the cabinet body. The front panel and the cabinet body are fixed by attaching a mounting base or the like on the inner side of the cabinet body and inserting a fixing screw from the base.

In the case of adopting the above-described configuration, in order to mount the fixed block requiring extremely high mounting accuracy on the inner side after assembling the cabinet main body, not only the workability is remarkably bad but also it is difficult to give accurate accuracy. . Moreover, the workability of assembly is also bad in that many fixing screws are required for fixing to the cabinet main body of a front panel.

In recent television receivers, in order to reduce the weight of the electric circuit components, blocks of the respective circuits are formed, and a structure having no chassis is provided. In the absence of such a chassis, the load of the CRT is applied to the front panel and, further, to the mounting portion of the front panel to the cabinet body. For this reason, it is required that the holding portion of the front panel in the cabinet body is sufficiently high in mechanical strength. However, if there is an increase in assembly parts and processes in order to increase the mechanical strength, the purpose of no chassis is attenuated.

Therefore, the present invention eliminates the above-mentioned defects as described above, solves the above problems caused by the absence of a chassis, increases the accuracy of the mounting position of the front panel with respect to the cabinet body, and also simplifies the assembly process. It is intended to provide a device capable of achieving sufficient mechanical strength.
