Description

[Detailed description of the invention] This invention connects a coaxial cable to a connector installed in a TV signal amplifier or distributor used indoors or outdoors, or a series unit installed on an indoor wall. The purpose of this product is to make it easy to connect to the stopper seat, and even with such a simple connection, to ensure that it is not firmly mechanically fixed. The purpose of the present invention is to provide a connecting tool that can be used in conjunction with other devices.

The drawings showing the embodiments of the present application will be described below.

In FIGS. 1 to 3, 1 is a board of a communal receiving device;
Reference numeral 2 denotes a well-known connector seat fixed to a substrate 1, which includes a main body 3 made of a metal material, a center conductor connection piece 4 made of an elastic metal material, and an insulator 5 to insulate both. It is empty.

In addition, in the main body 3, 6 is a seat part, 7 is an external conductor connection part,
A screw 8 is formed on the outer peripheral surface.

9 indicates a mounting screw portion. Next, in the connector 10, 11
The main body is made of a metal material (for example, brass, particularly JISH 342m cut brass is suitable) that has good electrical conductivity, good workability, and a certain degree of elasticity.

12 is an engagement protrusion formed on the inner peripheral surface of the main body 11;
It is formed in a spiral shape with the same pitch as the screw 8 of the external conductor connecting portion 7.

As clearly shown in FIG. 3, the slope 12a of this protrusion 12 in the pressing direction (direction of arrow A in FIG. 1), which will be described later, is a slope that is gentler than the slope 8a' of the thread 85 of the screw 8. (
The slope 12b on the side opposite to the pressing direction (direction opposite to arrow A) is steeper than the slope of the thread 8a (in this example, the surface perpendicular to the axis). It is a form of formality.

Reference numeral 13 denotes a bottom portion integrally formed with the main body 11, and numeral 14 denotes a coaxial cable fixing portion integrally formed with the bottom portion 13, which has the same shape as that of a well-known connector.

Reference numeral 15 indicates a through hole for inserting the internal insulator of the coaxial cable.

Reference numeral 16 denotes a center conductor provided at the axial center of the main body 11, and as is well known, the center conductor of a coaxial cable, which will be described later, can be used as is.

Reference numeral 17 denotes a slit formed in the main body 11, which extends parallel to the axis of the main body 11 from the end in the pressing direction as shown.

Next, reference numeral 18 indicates a well-known coaxial cable, which is separated from a jacket 19, an outer conductor 20, an inner insulator 21, and a center conductor 22.

A tightening ring 23 is used to fasten the coaxial cable 18 to the coaxial cable fastening portion 14.

When connecting the connector 10 with the above configuration to the plug seat 2, the main body 11 of the connector 10 is pushed over the external conductor connection portion 7 of the plug seat 2 in the direction of arrow A.

In this case, as shown in FIG. 3A, the slope 12a advances in the direction of the arrow while contacting the tip of the thread 8a.

For this reason, each part 11a, lla, .

), the protrusion 12 passes over the thread 8a.

Such crossing is performed for each thread 8a of the screw 8, and as shown in FIG. 3B and FIG. Physical fixing and electrical connection are distantly related.

In this connected state, the tips of the protrusions 12 are in contact with the slopes of the threads 8a, so that they are firmly fixed.

In this case, the center conductor 16 is also connected to the center conductor connector piece 4 as shown in FIG.

Next, FIGS. 4 and 5 show examples of how the connector 10 is used.

First, FIG. 4 shows a state in which the connectors 10 are respectively connected to the connector seats 2.2.2 closely provided on the bottom surface 25 of the community receiving device 24.

Since the connector 10 can be pushed over the external conductor connecting portion 7 of the connector seat 2 in the axial direction thereof, it is possible to Connections can be easily made.

FIG. 5 shows a state in which the connector 10 is connected to the faucet seat 2 provided in the series unit 26 provided on the wall of a room.

Next, FIG. 6 shows a different embodiment of the present application, in which the protrusion 1
This shows an example in which the slope 12be on the side opposite to the pressing direction in 2e is formed to have the same slope as the slope $a'e of the thread 8ae.

Even in this case, a firm fixation can be obtained as in the case described above.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

(Furthermore, the alphabets f9g and h are sequentially added to the following items based on the same idea, and redundant explanation will be omitted.

) Next, FIG. 7 shows an example in which the inner peripheral surface of the main body 11f is provided with a protrusion 12f only once.

Next, in Figure 8, six slits 17g are formed in the main body 11.
An example in which g is divided into six is shown.

Further, in this example, the slit 17g is designed to reach a part of the bottom 13g.

Next, FIG. 9 shows a concave groove 2 provided on the outer peripheral surface of the main body 11h.
7 is fitted with a ring 28 having the shape shown in FIG. 10 and made of an elastic material, and the main body 11
This shows an example in which the tightening force (force that attempts to contract the diameter) of h is increased.

As described above, in this invention, the slit 17 is formed in the main body 11, and the slope 12a on the pressing direction side of the protrusion 12 provided on the inner peripheral surface of the main body 11 is connected to the external conductor. Since the slope is gentler than the slope Ha' of the thread 8a at the outer conductor connection part, the main body 11
When connecting the main body 11 in a push-over manner, the diameter of the main body 11 can be easily expanded by pressing the main body 11 with a light force, and the diameter of the main body 11 can be easily expanded by the above-mentioned gentle slope 12a. The screw thread 8a can be easily climbed over, and the connection work can be easily performed.

Moreover, even if the electrical connection is made possible with a simple operation as described above, the inner peripheral surface of the main body 11 is provided with an engagement protrusion 12 having a chevron-shaped cross section, and the protrusion 1
Since the slope 12b on the side opposite to the pressing direction (the side in the removal direction) in 2 is steeper than the slope fJa' of the thread 8a in the external conductor connection part 7, electrical connection can be easily performed as described above. Just by making the connection, the protrusion 12 engages with the thread 8a of the external conductor connection portion 7, and a firm mechanical fixation can be established, and the connection can be firmly maintained. effective.

Moreover, even if the main body 11 is difficult to remove from the external conductor connection part 7 due to the steep slope 12b as described above, when the main body 11 is to be pulled out from the external conductor connection part 7 by grasping the main body 11 by hand, the external conductor connection Since the part 7 protrudes from the base plate 1, as shown in FIG. By relatively moving the finger 32 in the direction of the arrow 33, the external conductor connecting portion 7 and the main body 11 are connected.
It is possible to apply a large pulling force between the main body 11 and the main body 11, which is difficult to remove under normal usage conditions, so that when the operator wants to remove the main body 11, the main body 11 can be easily removed.
