Abstract

PURPOSE:To eliminate need of a connecting part for connection and make easy connection possible by connecting and fixing the core wire of a coaxial feeder by spring support, and connecting and fixing a coating wire with a clip of a hose band. CONSTITUTION:A cylinder part 2a of a terminal main body 2 covers a core wire 8a and an exposed part 8b of a coating wire of a coaxial feeder 8. A spring contact is formed in a hollow part of the cylinder part 2a through an electrostatic body at a coaxial position. This spring contact consists of a pipe of electric conductor, and the end of the pipe is folded, where a slit is provided to give a spring force. The core wire 8a of the feeder is inserted into the spring contact to be continuous electrically, and the core wire 8a and the coating wire 8b are bound by a clip for holding electric continuity. They can thus be jointed securely and easily without using a connector. Oxidation is prevented in addition, and stability to reliability and change by time can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input/output terminal attached to a transmitting/receiving facility that supplies high frequency signals using an unbalanced coaxial feed line.

[Conventional technology]

Conventionally, as this type of input/output terminal, there are cases where a coaxial connector is used and cases where a simple type input/output terminal is used.

In the former case, as shown in FIG.
It is of a structure that is screwed to 2.

In the latter case, as shown in FIG.
Insert the covered wire 8b coaxial with a into the fixing metal plate 22,
This structure is such that the covered wire 8b is fastened with a retaining screw 23.

[Problem to be solved by the invention]

In the conventional input/output terminal described above, when the coaxial connector shown in Fig. 4 is used, the structure requires that the connector be attached to the terminal side and the feeder line side, so the cost of parts increases. However, there were many disadvantages such as the laborious installation work and the need to attach connectors to both ends of the trunk line each time when transmitting/receiving equipment was connected in multiple stages. In addition, in the case of the simple terminal shown in Fig. 5, for example, the simple terminal used in television sets, etc., it is easy to sell to some extent, but the covered wire is exposed to the outside. It is easily oxidized and has disadvantages in terms of reliability and stability against aging. Furthermore, since the core wires are fixed with screws, accidents such as cutting of the core wires are likely to occur.

An object of the present invention is to provide an input/output terminal that eliminates the above-mentioned problems.

[Differences between the invention and the prior art]

In contrast to the conventional input/output terminal described above, the present invention has a structure in which the core wire of the coaxial feeder line is connected and fixed by spring support, and the covered wire is further connected and fixed with a hose band-like clip. When connecting, all the power supply lines at the connection part are protected by entering inside the terminal, and in addition,
The difference is that no other intermediate parts are used during connection, making connection extremely easy.

[Means for Solving the Problems] The present invention provides an input/output terminal attached to a transmitting/receiving equipment that supplies high-frequency signals using an unbalanced coaxial feed line, by crimping the core wire of the coaxial feed line to maintain electrical continuity. a spring contact, a clip that tightens the core wire of the coaxial power supply line and the coated wire on the coax to maintain an electrically conductive state, and exposed portions of the core wire and the coated wire of the coaxial power supply line that are electrically connected to the spring contact and the clip. This is an input/output terminal of a transmitting/receiving equipment, characterized by having a cylindrical portion covering a cylindrical portion.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

(Example 1) Figure 1 is a perspective view showing Example 1 of the present invention, Figure 2 (a)
is the same side view, and FIG. 2(b) is a cross-sectional view.

In the figure, the terminal main body 2 includes a cylindrical portion 2a and a mounting flange 2b. The present invention provides a spring contact 4 which is crimped to the core wire 8a of the unbalanced coaxial feeder line 8 to maintain electrical continuity, and a covered wire 8b coaxial with the core wire 8a of the coaxial feeder line 8 is tightened to the terminal body 2. Clip 3 that maintains electrical continuity
It has the following.

The spring contact 4 is made of an electric conductor pipe 4a, and has a structure in which the tip of the pipe 4a is folded inward and a slit is made in the folded part 4b to give it spring properties. By press-fitting into the portion 4b, the folded portion 4b is crimped to the core wire 8a by spring force to maintain electrical continuity. It is fixed with a dielectric material 5.

On the other hand, the clip 3 consists of a circularly curved ring-shaped tightening part 3a and flanges 3b provided at both ends of the tightening part 3a, and the ring-shaped tightening part 3a of the clip 3 is positioned in front of the spring contact 4. and the tightening part 3a is attached to the cylindrical part 2a of the terminal main body 2.
The front and rear ends are positioned using rings 6°6,
The flange 3b of the clip 3 is passed through a slit in the cylindrical portion 2a to protrude to the outside, and the tightening screw 1 is fastened between the protruding flanges 3b.

Next, the operation of attaching the unbalanced coaxial feeder line 8 to the input/output terminal according to the present invention will be explained based on FIG. 3. first,
Loosen the tightening screw 1 to expand the diameter of the ring-shaped tightening portion 3a. On the other hand, the core wire 8a of the coaxial power supply line 8 is exposed over a certain length, and a covered wire 8b coaxial with the core wire 8a is exposed over a certain length at a position rearward from the core wire 8a. Then, the coaxial feeder line 8 is attached to the ring-shaped tightening portion 3a of the clip 3.
The core wire 8a of the coaxial feed line 8 is press-fitted into the cylindrical folded portion 4b of the spring contact 4. The folded portion 4b of the spring contact 4 is crimped to the core wire 8a of the coaxial power supply line 8 by spring force, and maintains electrical continuity. on the other hand,
The clamping screw 1 is tightened between the flanges 3b of the clip 3, and the ring-shaped clamping portion 3a is crimped around the coated wire 8b of the coaxial power supply line 8 to maintain electrical continuity. As shown in FIG. 3, the terminal body 2 is mounted on a chassis 7, and a signal line 9 is connected to the spring contact 4.
