Description

[Detailed Description of the Invention] This invention relates to a high-frequency connector that is removed from a connector and a connector seat that are normally used when connecting a cable to an electronic device.

As shown in FIGS. 4 and 5, a cylindrical body 20 constituting the outer conductor is provided with a large number of slits 21 parallel to the cylindrical direction, and each of these slits is mutually connected to each other. The configuration is such that a large number of conductor elements 22 remaining between the connectors can easily adhere to the outer surface of the outer conductor of the connector.

However, with the above configuration, the high frequency signal cannot pass through the slit 21 portion, and as a result, the high frequency signal only passes through the conductor elements 22 between the slits.

When looking at this as a whole, the high-frequency signal does not pass through the entire circumference of the external conductor 20 evenly, but passes unevenly (unevenly distributed), which has the disadvantage of impeding the high-frequency electrical characteristics. there were.

Therefore, the present invention has been developed so that even if Surin 1 is provided on the cylindrical body (outer conductor) of the connector seat, it will not have much negative effect on the passage of high frequency signals, in other words, it will spread evenly over the entire circumference of the outer conductor. The present invention aims to provide a high-frequency connector configured to allow high-frequency signals to pass therethrough.

1 to 3 showing embodiments of the present application will be described below.

A is a connector for connecting a plug seat attached to the tip of a coaxial cable 4 for signal transmission, and this is an example of a well-known example, and 1 is a central conductor made of a metal bar. , 2 is an outer conductor located concentrically with the center conductor,
It consists of a hollow metal cylinder.

The bases of the center conductor 1 and the outer conductor 2 are kept insulated from each other, and 3 indicates an insulating cover that covers these parts.

Next, the plug seat B will be explained in detail.

Reference numeral 5 denotes a center conductor, which is usually formed of a hollow cylinder having an inner diameter slightly smaller than the outer diameter of the rod-shaped body 1, and is configured to have a crack formed in a part of the center conductor so that it can be slightly bent outward. However, when the rod-shaped body 1 is inserted, the two are tightly joined.

6 is an extending rod connected to the base of the central conductor 5;
It is integrally formed with a metal material.

Reference numeral 7 denotes an insulator for holding the center conductor, which is provided around the outer periphery of the rod, and is usually made of resin material, and is formed by a well-known insert method or other molding means.

Reference numeral 8 denotes an outer conductor located concentrically with the center conductor 5, which is made of a hollow cylindrical body made of a metal plate formed by press working like a normal conductor, and has a screw insertion hole 9' at one end. The mounting collar 9 is provided with a mounting collar 9 to enable attachment of the electronic device to the case 10, and the other end is provided with an embedded piece 11 as shown in FIG. 2 to enable connection with the insulator 7. be.

Further, in the cylindrical body 8, reference numerals 12 and 13 denote edges located on both sides in the direction of the cylinder core, and numerals 14 and the like denote a large number of slits bored at equal intervals between the both edges 12 and 13.
They are formed long in the direction of the cylinder, and are arranged side by side with their elongated directions inclined with respect to the cylindrical core 19.

Reference numerals 15 and the like indicate a large number of rectangular conductive elements formed between the slits 14.

Incidentally, the degree of inclination of each of the above-mentioned slots 14 is usually at the upper end 14 in at least one slot l- (see Fig. 3).
It is preferable that a and the lower end 14b are not located on the vertical axis (axis parallel to the cylindrical center) 16, that is, they are located far away from each other in the left and right directions.

Further, it is preferable that the width of each slit 1 is narrow and the distance between the slits is wide, but this is appropriately selected depending on the size or material of the cylindrical body 8.

Furthermore, the cylindrical body 8 is usually expanded so that the opening 8' on the connector insertion side (the portion of the one edge 12) has a slightly larger diameter than the outer diameter of the cylindrical body 2 on the connector side. The inner surface 15' of each conductor element 15 is designed so that the connector can be easily inserted, and the inner diameter of the middle portion (the portion where the conductor element is present) is formed to correspond to a diameter slightly smaller than the outer diameter of the cylindrical body 2. (
I-E- is configured to press into contact (elastically).

Further, considering the durability of the elasticity of the conductor element, the cylindrical body 8 is preferably formed of a metal plate having spring properties.

Next, when attaching the above-configured plug seat B to the case 10, use the mounting hole 10 of the case 10 in the same way as a normal one.
a, and in that state insert screws 17 and 17 into holes 9' respectively.
, 9', and screw it onto the female screws 10', 10' of the case.

After installation, the center conductor 5 and the electronic circuit inside the case are electrically connected via, for example, a lead wire 18, as shown in FIG.

Further, the external conductor 8 is connected to the ground part of the electronic circuit as necessary (it is necessary if the case 10 is made of plastic, and may not be necessary if the case 10 is made of metal).

For example, as shown by the two-dot chain line, a soldered lead wire 18' may be used, or a grounding section on a well-known printed circuit board on which an electronic circuit is formed may be placed close to the outer conductor 8. In this case, it is directly connected to the ground part by soldering.

Next, when connecting the connector A to the plug seat B attached to the ground, the connector A can be smoothly connected by simply pushing the connector A through the opening 8' of the plug seat B.

In the state where they are connected in this way as shown in Figure 2,
The other center conductor 1 is closely fitted into one center conductor 5, and the outer surface of the outer conductor 2 of the connector is tightly attached to the inner surface of the outer conductor 2 of the connector seat (mainly the inner surfaces of the multiple conductor elements 15). A solid mechanical connection and a good electrical connection are obtained.

Moreover, since each slit 14 provided in the outer conductor 8 of the plug seat is diagonal, the remaining state of the conductor seen from the signal passing direction (direction of the cylinder core) is almost uniform over the entire circumference.
As a result, high frequency signals can pass through in a substantially good condition.

As described above, in this invention, the cylindrical body 8 constituting the external conductor on the side of the plug seat has both edges 12 in the direction of the cylinder center.
, 13 are arranged in parallel in the middle to form a large number of conductor elements 15. Therefore, when the connector A and the connector seat B are fitted together, each of the above-mentioned A large number of conductive elements 15 in the form of rectangles
is in close contact with the outer circumferential surface of the outer conductor 2 on the connector side, making it possible to integrate the two, and controlling good high-frequency transmission without causing deterioration of electrical characteristics in that part (for example, effects due to poor contact). effective.

Moreover, in the present invention, as described above, the cylindrical body 8 of the connector seat
By arranging a large number of slits 14 in parallel, even if the structure causes uneven distribution of high-frequency signal passages in the cylindrical body (if there are slits, high-frequency signals cannot be transmitted there, Even though the high frequency signal passing through the cylinder cannot be transmitted evenly around the entire circumference and may impede the high frequency characteristics), each of the slits 14 is inclined with respect to the cylinder center. Along with this, a large number of conductor elements 15 are also arranged in parallel in an inclined state, so when looking at the distribution state of these from the direction in which the high frequency signal passes (viewed from the direction parallel to the cylinder core), on each passing line The remaining amount of a certain conductor is almost uniform over the entire circumference, and therefore the passage state of the high-frequency signal is almost uniform over the entire circumference. Even in a configuration in which a large number of slits 14 are provided to improve contact between the inner surface of the external conductor 8, the adverse effects caused by the provision of the slits can be eliminated, and the high-frequency signal passing through the external conductor 8 can be uniformly distributed all around the circumference. This has the excellent effect of allowing signal passage through distribution.
