The terminal part for connecting the television and connecting the shield wire to the substrate provided in the shield case is provided. That is, the following has been announced as such a TV outlet.

Japanese Utility Model Laid-Open No. 59-118281 discloses a boss portion (output terminal) for fitting an outer contact in which a through hole for inserting a central contact is formed axially as an inexpensive TV outlet having a high shield effect. Part) and a thermoplastic resin cover having a mounting means for mounting to a mounting frame, and two U-shaped parts made of conductor and fitted to each other, and a shield case in which these are locked and fixed is adopted. It has been announced that a substrate on which electronic components are mounted is provided in the shield case.

Although the above-mentioned conventional ones have their respective merits, a considerable number of man-hours are required for assembling them. That is, a case made of an insulating material, a ground terminal in the case, a contact pin,
It is clear that the installation and fixing of the insulating part, the circuit board, the chassis, etc. are required, and the coaxial cable is also required to be installed. It is inevitably complicated and inevitably requires a great deal of labor for distribution, repair, and inspection.

[0007] Regarding the above-mentioned proposals, even if each part is required to have some effect, there is basically no improvement in mounting and assembling of the outlet as a whole. In particular, since brazing, soldering, or twisting is required for mounting and fixing the above-mentioned respective parts, not only the mounting and assembling but also inspection and repair work are doubled.

Further, as described above, such outlets are set in a limited space such as an iron box buried in the wall surface, or in combination with other switches or outlets. In addition, since a coaxial cable having a diameter larger than that of a mere conductor wire or lead wire is introduced and connected, inductive connection of the coaxial cable at both end surfaces is not easy and stable connection tightening is difficult to obtain.

(3) A cover engaging portion is provided opposite to the insulating case, and locking claws provided opposite to the chassis cover are engaged with the cover engaging portions. The television outlet according to item (1).

[0013]

A locking portion for supporting and setting the circuit board in an inclined shape with respect to the width direction axis of the mounting bottom surface in the middle of the chassis is provided between the coaxial cable mounting seats oppositely disposed on both sides of the chassis. By setting and supporting the circuit board on the coaxial cable mounting seat, the coaxial cable can be stably mounted by the relatively wide cable saddle at the coaxial cable mounting seat, and the coaxial cable can be stably and appropriately introduced into the cable saddle.

By supporting and setting the circuit board between the coaxial cable mounting seats as described above, the front and back surfaces of the circuit board are completely exposed when the chassis cover is removed, and the circuit connecting portion and the electronic components installed are formed. Make it easy to repair and inspect parts.

By providing a contact fixing insulator holding a contact pin at the center of the bottom surface of the case made of an insulating material, and fixing the setting relation position of the contact fixing insulator by supporting and setting the circuit board on the chassis, the contact pin is fixed. Also, by inserting the contact fixing insulator into the case and setting the circuit board, an appropriate mounting relationship between them is formed without requiring special fixing means or fixing process.

A cover engaging portion is provided opposite to the insulating case,
By engaging the locking claws provided opposite to the chassis cover with the cover engaging portions, it is possible to fix the circuit board inserted as described above with the chassis cover and the chassis. The cover fixes the coaxial cable mounting portion of the case to stabilize and ensure the mounting relationship of each component body, and facilitates the whole assembly and disassembly.
