Description

[Detailed Description of the Invention] The present invention relates to a terminal board device, and particularly relates to a terminal board device, in which a terminal board and a conductive member that is electrically connected by this terminal board can be independently attached to a device body such as a cabinet or a base body such as a chassis. It is structured.

Conventionally, rod antennas used in electronic devices such as radio receivers and tape recorders with radio receivers are
With the configuration shown in the figure, electrical conduction is achieved with a tuner section disposed within the main body of the device.

In the antenna shown in FIG. 1, a rod antenna 1 is inserted into an antenna insertion part 3a formed in a cabinet 2, and a screw 4 is inserted into a tongue piece 3 for installation with a screw insertion hole provided at the base end. When installing the lead wire to the cabinet 2, the lead wire 5 connected to the tuner section disposed inside the device body is soldered between the tongue piece 3 and the inner surface of the cabinet 2. The terminal plate 7 connected to the tuner section 6 is inserted into the screw 4 through the screw insertion hole, and is fixed at the same time as the rod antenna 1, thereby establishing electrical continuity between the tuner section and the rod antenna 1. There is.

The terminal plate 7 is attached to the antenna terminal mounted on the inner surface of the cabinet 2 by inserting the boss insertion hole into the boss 8 to prevent rotation.

In a structure in which the terminal plate 7 is attached to the base end side of the rod antenna 1 to establish electrical continuity between the rod antenna 1 and the tuner section, for example, due to the structure of the device, the tuner section may be connected to the rod antenna 1. When placed on the upper side of the device, the lead wire 5 is arranged along an electric circuit section other than the tuner section, which is arranged between the tuner section and the base end of the rod antenna 1. As a result, it is influenced by the electric circuit section and causes out-of-tuning.

In addition, items such as the rod antenna 1 that are extended from the cabinet 2 and are likely to be damaged during use must be replaced as necessary, but such items as shown in Figure 1 mentioned above cannot be replaced. Since the terminal plate 7 must also be removed when replacing the rod antenna 1, it is not possible to remove the screw 4 and remove only the rod antenna 1 independently for replacement.

Therefore, when replacing the rod antenna 1, the cabinet 2 must be opened and the replacement work is extremely difficult.

Therefore, the present invention has a structure in which the terminal board and the conductive members such as rod antennas that are electrically connected by the terminal board are each independently attached to the equipment body such as a cabinet or a board such as a chassis, and the above-mentioned conductive members can be replaced. In addition to making it easier, the conduction position between the conductive member and the terminal board can be freely selected, and the lead wire connecting the conductive member and the specified electric circuit section is not adversely affected by other electric circuit sections. This is how it was done.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

FIG. 2 shows an example in which the present invention is applied to the case of establishing electrical continuity between a rod antenna 11 and a tuner section provided in the main body of the device. The lead wires are attached from a base 16 provided with a fitting part 15 that is inserted and fitted into a boss part 14 that is integrally planted on a base 13 of a cabinet or the like formed of metal and molded with synthetic resin. 17 and an elastic contact piece 18 as shown in FIG.

The elastic contact piece 18 is formed by bending the tip of the connecting piece 19 extending from the base 13 and further extending it, and the elastic contact piece 18 is in contact with one side of the rod antenna 11 which is a conductive member. A contact portion 20 is provided for electrical conduction.

Further, a screw insertion hole 2 for fixing the terminal plate 12 to the base body 13 is bored in the connecting piece 19 portion.

The terminal board 12 formed as described above has the fitting portion 15 fitted into the boss portion 14 set on the base 13, and the fixing screw 22 is inserted through the screw insertion hole 21. By fixing this screw 22 to a screw fixing portion 23 set on the base body 13, it is attached to the base body 13 as shown in FIG.

After the terminal plate 12 is attached in this way, the rod antenna 11 is inserted into the antenna insertion part 24 formed on the base 13, and the screw insertion hole provided at the base end is installed by inserting the screw into the tongue piece 25. 26 is inserted from the outside of the base 13 to fix the rod antenna 11, the contact portion 20 of the elastic contact piece 18 provided on the terminal plate 12 comes into contact with one side of the rod antenna 11 under elastic deflection force. , rod antenna 11
Conductivity is established between the terminal board 12 and the terminal board 12.

The lead wires of the terminal plate 12 are attached to the portion 17 through the lead wires 27 connected by soldering or the like to establish electrical continuity between the rod antenna 11 and the tuner portion disposed within the main body of the device.

FIGS. 4 and 5 show another embodiment of the present invention, in which the terminal plate 12 can be fixed to the base body 13 without using fixing screws 22. In this case, a pair of elastic clamping pieces 29 and 29 are provided on the base 16 provided with the fitting portion 15 of the terminal plate 12, and a pair of elastic clamping pieces 29 and 29 are provided with a locking claw 28 at the tip. The engaging recess 31 that engages with the rib 30 provided on the surface is connected to the fitting part 1.
5 consecutively.

Then, when the engagement recess 31 is engaged with the rib 30 and the fitting part 15 is inserted and fitted into the boss part 14, the terminal plate 12 is prevented from rotating due to the engagement between the engagement recess 31 and the rib 30. , the boss portion 1 is held by the pair of elastic clamping pieces 29 and 29.
4 is fixed to the boss portion 14 of the base body 13 in such a manner as to sandwich it therebetween.

Here, as in the case described above, the rod antenna 11 is attached to the base 1.
3, the lead wire of the terminal plate 12 can be attached between the rod antenna 11 and the tuner section in the main body of the device at section 17.
Continuity is achieved through a lead wire connected to.

In the terminal plate device according to the present invention as described above, a conductive member such as a rod antenna can be attached independently of the terminal plate, so that only the conductive member can be independently removed if necessary.

Particularly in the case of the above-mentioned rod antenna, the rod antenna can be removed simply by removing screws inserted from the outside of the cabinet serving as the base, making it extremely easy to replace or repair the rod antenna.

In addition, since the terminal board can be mounted independently at a desired position where it can come into contact with the conductive member, it becomes possible to arrange the lead wire in a place where it is unlikely to be adversely affected by various electric circuits and to achieve conduction. Flexibility can be provided in the design of electronic devices such as radio receivers.

Furthermore, according to the present invention, the installation position of the terminal board is determined by fitting it into the boss, making installation extremely easy, and in particular, it can be installed even in a small space inside the device. becomes.

Although the above-mentioned embodiment has been described with reference to the case where the rod antenna is intended to be electrically conductive, the present invention is not limited to this case and can be applied to various other parts that require electrical conduction.
