Description

[Detailed Description of the Invention] The present invention relates to a terminal device used in radio receivers, television receivers, etc., and is designed to provide a stable connection state with a simple configuration.

Generally, in radio receivers, television receivers, etc., antenna terminals are formed in the same shape on both the positive and negative sides.

The commonly used terminal structure is simply a terminal block with an insert pin with a cap-shaped knob at the tip screwed together.The lead wire is wound around the insert pin and the lead wire is tightened by tightening the insert pin. is sandwiched between a terminal plate and a cap-shaped knob, and crimped onto a butterfly pin.

By the way, in this type of conventional terminal device, not only when a normal lead wire is used as the antenna lead wire, but even when using a coaxial cable, the core wire and the braided wire are individually wrapped around the butterfly pin. Needs to be tightened.

This makes it especially difficult to connect the braided wires, and there is a problem in that the braided wires come apart after being tightened once, making the connection state unstable.

The present invention eliminates the above-mentioned drawbacks of the prior art, and provides an excellent terminal device that is extremely easy to connect, especially when using a coaxial cable, and whose installation is extremely stable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The terminal device of the present invention will be described below with reference to drawings of one embodiment.

In the figure, 1 is a terminal board made of synthetic resin or other insulating board, 2 is a board mounted on the front surface of the terminal board 1, 3 and 4 are fastening fittings each mounted on the back surface of the terminal board 1, and 5 and 6 are Similarly, the terminal pieces 7 and 8 attached to the back surface of the terminal board 1 have a cap-like knob 9.10 at the tip, and the above-mentioned tightening metal fitting 3
, 4 is an insert pin screwed into the screw hole 4; 11 is a coaxial cable fixing fitting that is fitted into the insert pin 7 and has a U-shaped bent portion 11a at the tip; 2a is a U-shaped U-shaped fixing fitting 11; Bending part 11
This is a knurled portion formed on a part of the substrate 2 facing a.

Note that the insert pin 7 is provided at a slightly higher position than the insert pin 8, and the position of the U-shaped bent portion 11a of the coaxial cable fixing fitting 11 fitted to the insert pin 7 is the same as that of the insert pin 8. They are set at the same height.

In the above embodiment, when a normal lead wire is used as the antenna lead, one lead wire is wound around the insert pin 7, the other lead wire is wrapped around the insert pin 8, and the insert pins 7 and 8 are tightened respectively. That's fine.

When a coaxial cable is used as the antenna lead, the braided wire 12 of the coaxial cable 12 as shown in FIG.
A is exposed on the outer periphery of the coaxial cable 12, this part is inserted between the U-shaped bent part 11a and the knurled part 2a of the coaxial cable fixing fitting 11, and the core wire 12b of this coaxial cable 12 is wound around the insert pin 8. By attaching and tightening, the coaxial cable 12 can be easily electrically connected to each terminal piece 5, 6.

In this case, the coaxial cable 12 is firmly tightened and fixed by the fixing fitting 10, and the knurling part 2a bites into a part of the outer periphery, so the installation state of the coaxial cable 12 itself becomes extremely stable, and the braided wire 12 A can be electrically connected to the fixing fitting 11 by simply turning it over and exposing the entire outer periphery of the coaxial cable 12 without having to twist it into a linear shape each time, making the connection work easier.
The electrical connection also becomes extremely stable.

Claims (1)

[Scope of utility model registration request] Attach a board and a clamp to the front and back sides of the terminal board, respectively, screw together a pair of insert pins each having a cap-shaped knob at the tip of the board and the clamp, and attach the tip to one of the insert pins. A fixing fitting having a bent part for fixing the coaxial cable is fitted to the fixing fitting, and a knurled part is formed on the surface of the substrate opposite to the bent part of the fixing fitting, so that the braided wire exposed on the outer periphery of the coaxial cable is fixed. Insert it between the bent part of the fixing metal fitting and the knurled part of the board, and tighten one of the insert pins to tighten the fixed metal fitting with its cap-like knob, and connect the bent part to the exposed braided wire. A terminal device in which the core wire of the coaxial cable is wrapped around the other insert pin, and the core wire is crimped to the other insert pin by tightening the other insert pin.
