The present invention relates to a mounting structure of a novel antenna terminal plate. Specifically, the present invention relates to a structure in which an antenna terminal plate installed in an electronic device having a function of receiving broadcast waves such as a television receiver, an FM receiver, and the like is installed in the chassis, and the antenna terminal plate is very simple to a support member installed in the chassis. It is an object of the present invention to provide a new antenna terminal plate mounting structure that can be installed by the device and that the workability in the manufacturing process of this kind of device can be improved.

In the structure of the antenna terminal plate of the present invention, the antenna terminal plate provided with the antenna input terminal is provided on the support member provided in the chassis of the electronic device, and the engagement portion formed on the support member by the antenna terminal plate and the sliding movement can be engaged freely. By providing the part, the antenna terminal plate can be at least temporarily installed on the supporting member, thereby improving workability in the manufacturing process of this kind of equipment.

For example, in an electronic apparatus having a function of receiving broadcast radio waves such as a television receiver or an FM receiver, an input terminal is usually provided in a state of being fixed to an appropriate member of a plate or relatively thin case shape, that is, an antenna terminal plate. In addition, there are various types of such antenna input terminals. Conventionally, for example, a type such as that found in Japanese Utility Model Publication No. 49-13048, i.e., stripping the lead wire from one end of the feeder line, In general, a type of fastening it to a connection member is generally used. However, in recent years, a connector connected to one end of an antenna cord, such as a feeder wire or a shield wire, is detachably fitted, and thus the antenna cord and the antenna input terminal Many types of connection (hereinafter, referred to as connector type antenna input terminals) have been used.

By the way, such an antenna terminal board needs to be installed so that the antenna input terminal and other input terminals may be located outward from the outer case of the electronic apparatus, for example, a cabinet of a television receiver, in the state where it is installed in the electronic apparatus. For this reason, the antenna terminal plate is appropriately installed at the position toward the cabinet of the chassis member fixed directly to the cabinet or disposed inside the cabinet, as shown in Japanese Utility Model Publication No. 49-13048 described above. It is attached to the support member.

FIG. 8 shows an example of a mounting structure of a conventional antenna terminal plate in which an antenna terminal plate is fixed to a support member provided in the chassis.

In the figure, a is an antenna terminal plate. The antenna terminal plate a is formed almost in a plate shape, and a fixing swelling b b (only one of which is shown in the drawing) is formed, through which fixing screws are inserted at both ends in the longitudinal direction thereof. c is a well-known connector type antenna input terminal fixed to the center part of an antenna terminal board (a), and this antenna input terminal (c) has the fitting part (d) in the back of an antenna terminal board (a), ie, in the figure In the state which protrudes from the surface toward the right side, it is being fixed to the antenna terminal board a by the nut e. The base f of the fitting portion d of the antenna input terminal c is formed into a substantially cylindrical shape by a conductive metal material, and the base f is a grounding conductor and at the same time the base f is The signal terminal g is disposed in the center of the circuit, and an insulating member h is provided between the signal terminal g and the base f.

i is a rear case which constitutes a cabinet of a television receiver, and since this rear case i is combined with the front case which is not shown in figure, an almost box-shaped cabinet is formed.

j is an opening for antenna terminal plate arrangement formed in the rear portion of the rear case i.

k is a chassis board supported on the front case side (not shown). The chassis substrate k is provided with a predetermined circuit, and at the same time, the base f of the circuit and the antenna input terminal c and the signal terminal g ) Is grounded by a conductor (not shown).

l is a supporting member of the antenna terminal plate fixing yaw fixed to the rear long part of the upper surface of the chassis substrate k, and this supporting member l is hooked from above by the sheet metal material. At the same time it is formed in the shape of The supporting piece m (only one of which is shown in the drawing) is integrally formed so as to roll at right angles in opposite directions from each of the two opposing ends in the shape of each other. The hole n is formed.

Thus, the antenna terminal plate a is fixed to the support member 1 by screws Q screwed into the holes n of the support member 1 through the installation holes b.

In addition, when the rear case i of the cabinet is combined with the front case (not shown), the antenna terminal plate a is positioned to close the opening j formed in the rear case i, whereby the antenna input terminal ( The fitting portion d of c) is located outside the cabinet.

p is a connector provided at one end of the antenna cord q (shield wire), and is fitted with a fitting tube r that fits tightly from the outside to the base f of the fitting portion d of the antenna input terminal c. It has the signal pin s arrange | positioned at the center part of the cylinder r. However, when the fitting tube r (connected with the shield) of the connector p is fitted outside the fitting portion d of the antenna input terminal c, the signal pin s on the connector p side (Connected with the core wire) and the signal terminal q on the antenna input terminal c are fitted, whereby a circuit formed on the chassis substrate k and an antenna (not shown) are connected.

According to the mounting structure of the antenna terminal board shown in FIG. 8, some problems arise in the operation | work in the manufacturing process of this electronic device, especially the occupation process in an inspection process or adjustment fixing.

That is, according to the mounting structure of the antenna terminal plate shown in FIG. 8, the antenna terminal plate a is supported only by the screwing on the support member 1 provided in the chassis board k. Therefore, in the process until the manufacture of the television receiver is completed, for example, in order to check whether the antenna input terminal c is defective, the operation of fitting the connector p to it and pulling it out is performed. In this case, the operation of fitting or withdrawing the connector p to the antenna input terminal c is performed.

However, since the antenna input terminal c and the connector p are easily fitted in the fitted state, it is not necessary to pull this easily and strongly to the extent that the connector p is lightly pulled out during the operation as described above. However, in doing so, a strong tensile force may be applied to the support member 1 so that the support member 1 may be deformed or, in some cases, peeled off the chassis substrate k.

Thus, conventionally, the antenna terminal plate a is screwed to an appropriate support member other than the support member 1 until the work related to the antenna input terminal c is completed, and the inspection work performed in this state or The handling as the adjustment work is performed.

When the antenna terminal plate a is handled in this way, not only an extra jig is required, but also the work of screwing the antenna terminal plate a is required at least twice, so the workability is bad, and in some cases, A problem arises in that the conductor connecting the antenna input terminal c and the circuit on the chassis substrate k is made longer than necessary.

Thus, the installation structure of the inventive antenna terminal plate is characterized by forming an engagement portion in which the antenna terminal plate is engaged by almost one operation with respect to the support member on which the antenna terminal plate is supported.

Therefore, according to the present invention, when the antenna terminal plate is temporarily installed on the supporting member, the flame adjustment is performed, and when the connector of the antenna cord side is removed from the antenna input terminal or when the connector is fitted to the antenna input terminal, the antenna terminal plate is mounted on the supporting member. When the replacement is performed, the stress at the time of replacement or installation is not applied to the support member. In addition, the antenna terminal plate temporarily attached to the support member only allows the antenna terminal plate to be pulled out in a predetermined direction, i.e., the replacement and installation of the support member can be performed by one very simple operation, so that the work efficiency does not decrease.
