Abstract

PURPOSE:To reduce the number of parts and parts to be soldered by a method wherein a coaxial connector is structured so that an SMA type connector can be removed. CONSTITUTION:A connecting part 2 is soldered at the end of a coaxial cable 3, and a male screw part 10 of an SMA type connector 1 is screwed into a female screw part 22 formed at the center of its flange part 21 to realize a structure with the SMA type connector l mounted at the end of the coaxial cable. At the connection part 2, a center conductor 6 of the coaxial cable protrudes from the center of the flange part 21. A center pin 5 of the connector 1 is of double socket contact type, and the coaxial cable wherein the tip of the center conductor 6 has been processed in a cone shape is inserted into this pin 5. At the time of packaging an antenna, the connector 1 is removed, an antenna element 10 is soldered to the center conductor with the connection part 2 left at the coaxial cable end and the connection part 2 is connected to a machine console 13 by a screw 24.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a coaxial connector, and particularly to a coaxial connector suitable for coaxial cables.

[Prior Art] Conventionally, a single connector has one fixed state, for example, when realizing a panel mount receptacle at the end of a coaxial cable.

As shown in FIG. 5, a panel mount receptacle type female coaxial connector 14 and a coaxial cable 3
A mail-type coaxial connector 15 is mounted on the end of the cable. 10 is an antenna element, 11 is a dielectric, 12
1 is a matching adjustment sleeve, and 13 is a device housing.

[Problems to be Solved by the Invention] In the conventional structure described above, for example, when considering power feeding to an antenna, the number of parts is 2 (male type, female type coaxial connector), even if you look only at the connection part. The number of soldering points is 3. However, considering the equipment on board a satellite,
materials and manufacturing costs.

From the viewpoint of reliability (which deteriorates in proportion to the number of parts, number of soldering points, etc.), it is required to reduce the number of parts and soldering points as much as possible.

[Means for Solving the Problems] A coaxial connector according to the present invention includes a connecting portion at an end of a coaxial cable, and the connecting portion has a flange and a female threaded portion at the center. The center conductor of the coaxial cable is protruding.

The present invention is characterized in that an SMA type connector having a socket contact at the center and a male threaded portion screwed into the female threaded portion of the connecting portion is detachably attached to the connecting portion.

[Embodiment] FIG. 1 is a sectional view of an embodiment of the present invention. A connecting part 2 is soldered to the end of the coaxial cable 3, and the male threaded part 10 of the SMA type connector 1 is screwed into the female threaded part 22 formed at the center of the flange part 21, so that the end of the coaxial cable 3 An SMA type connector 1 (female type in this case) is attached to the connector. Connection part 2
Again.

As shown in FIG. 2, the center conductor 6 of the coaxial cable 3 protrudes from the center of the flange portion 21. Here, SMA
The center pin 5 of the type connector 1 is of the type with socket contacts on both sides, and the center conductor 6 of a coaxial cable (here, a semi-rigid cable φ3.6 mm) is connected to this center pin 5.
A cone-shaped tip is inserted. Also,
This coaxial connector connects connection part 2 to SMA type connector l.
The second figure shows each of the divided states.
Figure 3. In FIG. 2, 23 is a hole for screwing, and in FIG. 3, 4 is a dielectric.

Figure 4 shows an example using the above coaxial connector.
Power feeding part of whip antenna element 10 (not shown)
The case where it is used is shown.

When adjusting the electrical characteristics, the characteristics of the power feeder connected to the coaxial cable 3 are measured in the state shown in FIG. 1. When mounting the antenna, remove the SMA type connector 1, solder the antenna element 10 to the center conductor 6 while leaving the connection part 2 at the end of the coaxial cable, and fix the connection part 2 to the device housing 13 with the screw 24. By doing so, an antenna connection structure as shown in FIG. 4 is obtained.

[Effects of the Invention] As explained above, the coaxial connector according to the present invention has S
By making the MA type connector detachable, S
It is characterized in that it can be used in two forms, as an MA type connector or a flange mount receptacle type coaxial connector.

By using this coaxial connector, it is possible to measure the same electrical characteristics as before, for example, at the connection between an antenna element and a power feeder, which previously required a combination of P type and J type connectors. The number of parts and soldering can be reduced.

This is particularly effective in improving the reliability of satellite-borne equipment.
