BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coaxial type ammunition connector used for communication equipment and the like.

[0002]

2. Description of the Related Art In a communication system which requires high reliability, a transmission system often has a multiplexing structure. FIG. 11 is a diagram showing a configuration example of a main part of a multiplex communication device having a multiplexing / demultiplexing circuit. In the figure, 70-N is a working demultiplexing circuit,
70-E is a backup system demultiplexing circuit. These working system demultiplexing circuit 70-N and standby system demultiplexing circuit 70-E are
The switch circuit 72a and 72b of the switch board 72 are connected to the switch 1 selectively.

By the way, in such a device, when a failure occurs in the switch board 72, the switch board 72 is removed to repair the switch board 72. Then, the active system demultiplexing circuit 70-N and the standby system demultiplexing circuit
Both of the 70-E are disconnected from the transmission line 71, resulting in disconnection of communication.

Therefore, as shown in FIG. 12, the switch board 7
In the state where 2 is removed, it is desirable to connect the transmission line 71 to the active system demultiplexing circuit 70-N. To achieve such a structure, an ammunition connector is used as a connector for connecting the switch board 72.

On the other hand, FIG. 13 is a diagram showing a configuration example of a main part of a multiplex communication device in which a transmission line has a multiplex structure. Reference numeral 70 denotes a demultiplexing circuit, which is a 0-system transmission line 71-0 and a 1-system transmission line 71-1.
Are selectively selected and connected by the switching circuits 73a and 73b of the switch board 73.

In the apparatus having such a configuration, different parties may be connected via the 0-system transmission line 71-0 and the 1-system transmission line 71-1. In this case, an ammunition connector is used as a connector for connecting the switch board 73, and when the switch board 73 is removed, the transmission line 71-0 is connected to the demultiplexing circuit 70 as shown in FIG. If, for example, the switch board 73 is removed from the state where the 1-system transmission line 71-1 is connected to the demultiplexing circuit 70 as shown in FIG. Will be connected to transmission line 71-0,
A misconnect will occur. Therefore, in such a case, a connector having no ammunition function is used.

As described above, the connector for connecting the switch board may or may not need the ammunition function. Depending on the switching mode of the switch board, the ammunition function may be used. You have to distinguish between the type with and the type without ammunition function. Therefore, when manufacturing a device using a connector with a bullet function and a device using a connector without a bullet function, it is necessary to prepare a connector for each type. This leads to higher costs and more complicated parts management at the manufacturing site.

Further, in a multiplex communication device or the like, a circuit requiring an ammunition function and a circuit not requiring an ammunition function are often mixed. In this case, it is necessary to properly use the two types of connectors for manufacturing one device, which further complicates the component management and increases the number of processes because the two types of connectors must be mounted respectively. Will be invited.

It is a BB arrow sectional view inside. In the figure, reference numeral 1 is an element body made of an insulating material such as resin. In this element body 1, two cylindrical portions 1a and 1b having the same diameter and length are arranged in parallel, and the cylindrical portions 1a and 1b are connected by a connecting portion 1c at the central portion in the longitudinal direction. Make a shape. The width of the connecting portion 1c in the direction along the longitudinal direction of the cylindrical portions 1a and 1b is smaller than the length of the cylindrical portions 1a and 1b in the longitudinal direction. Therefore, the element body 1 has four cylindrical protrusions, which are the first terminal 10-1, the second terminal 10-2, the third terminal 10-3, and the fourth terminal 10-4, respectively. .

The element body 1 has a cylindrical portion 1a,
Internal space 11 reaching near both ends along the axis of 1b
-1, 11-2 are provided respectively. Further, the element body 1 is provided with an internal space 11-3 that connects the internal space 11-1 and the internal space 11-2 in the connecting portion 1c. The internal spaces 11-1 and 11-2 are communicated with the outside of the element body 1 through openings 12-1, 12-2, 12-3 and 12-4 formed at the ends of the element body 1. Openings 12-1, 12-2, 12
-3 and 12-4 form circular openings centering on the axial centers of the cylindrical portions 1a and 1b. This opening 12-1, 12-2, 12-3, 12
-4 has an opening area having a diameter slightly larger than the diameter of the central electrode of the plugs inserted into the first terminal 10-1 to the fourth terminal 10-4, for example.

Open contacts 2-1, 2-2 and a closed contact 3 are arranged inside the internal spaces 11-1 to 11-3. Each of the open contacts 2-1, 2-2 is made of a plate-shaped conductive member whose both ends are bent to the same plane. The open contact 2-1 has its central portion fixed to the element body 1 at the longitudinal center of the cylindrical portion 1a. Both ends of the open contact 2-1 extend to the vicinity of the opening 12-1 on the terminal 10-1 side and the vicinity of the opening 12-2 on the terminal 10-2 side, respectively, and do not reach the axis of the cylindrical portion 1a. To some extent, it projects to the extension of the openings 12-1 and 12-2.
The open contact 2-2 has a cylindrical portion 1b at the center thereof.
Is fixed to the element body 1 at the center in the longitudinal direction. Both ends of the open contact 2-2 extend to the vicinity of the opening 12-3 on the terminal 10-3 side and the vicinity of the opening 12-4 on the terminal 10-4 side, and do not reach the axis of the cylindrical portion 1b. To some extent, it projects to the extension of the openings 12-3 and 12-4.

The close contact 3 is made of a conductive member having a U-shape. The close contact 3 has one end located near the opening 12-1 on the terminal 10-1 side,
The other end is connected to the terminal 10-1 of the internal space 11-1 and the terminal 10-3 of the internal space 11-3 and the terminal 10-3 of the internal space 11-2.
It is arranged so as to extend to the vicinity of the opening 12-3 on the side and is fixed to the element body 1. Closed contact 3
Are arranged in positions near the opening 12-1 and in the vicinity of the opening 12-3, apart from the extension lines of the opening 12-1 and the opening 12-3, and at this position, the open contacts 2-1 and 2-2
Are in contact with each other. On the other hand, the outer surface of the element body 1 is covered with a shell 4 made of a conductive material in most regions except both ends of the cylindrical portions 1a and 1b.

Each of the connector elements E having the above structure is used as follows. That is, the first terminal 10-1 to
As shown in FIG. 3, the coaxial cable 5 is directly connected to the fourth terminal 10-4 via a plug 6 for use.

The plug 6 has a pin-shaped central electrode 6a and a cylindrical shield electrode 6b having the central electrode 6a as an axis. The coaxial cable 5 is attached to the central electrode 6a.
Internal conductor 5a is connected. In addition, the shield electrode 6
The outer conductor 5b of the coaxial cable 5 is connected to b. The inner diameter of the shield electrode 6b is substantially the same as the outer diameter of the cylindrical portions 1a and 1b of the element body 1.

Now, when the plug 6 is inserted into the third terminal 10-3 as shown in FIG. 3, the central electrode 6a is inserted into the opening 12-3 and its tip reaches the internal space 11-2. To do. Then, the end of the open contact 2-2 on the side of the third terminal 10-3 comes into contact with the central electrode 6a, and is pushed outward by the central electrode 6a to be separated from the closed contact 3. Further, the shield electrode 6b comes into contact with the shell 4.

Thus, if another coaxial cable is connected to the fourth terminal 10-4, the coaxial cable 5 connected to the plug 6 is connected to the fourth terminal 10-4 via the open contact 2-2 and the shell 4. It will be connected to the coaxial cable connected to -4. This is the first terminal 10-1 and the second terminal 10
-2 is the same, the first terminal 10-1 and the second terminal
If a coaxial cable is connected to both 10-2, both coaxial cables are connected via the open contact 2-1 and the shell 4. The conduction state at this time is shown in FIG.

The high frequency signal is transmitted through the open contacts 2-1 and 2-2, but the periphery of the open contacts 2-1 and 2-2 is shielded by the shell 4, and the shell 4 is Since they are electrically connected to the external conductors of each coaxial cable, the transmission characteristics of high-frequency signals at the open contacts 2-1 and 2-2 are almost the same as the transmission characteristics of the coaxial cable. That is, if a coaxial cable is connected to each of the first terminal 10-1 to the fourth terminal 10-4, the cylindrical portion 1
Each of a and 1b functions as if it is a coaxial cable, and is a coaxial cable connected to the first terminal 10-1,
The signal transmitted through the coaxial cable connected to the open contact 2-1 and the second terminal 10-2 or the coaxial cable connected to the third terminal 10-3, the open contact 2-2 and the fourth terminal 10-4 When viewed from the signal transmitted through the connected coaxial cable, it is similar to the case where one coaxial cable is transmitted.

On the other hand, when the plug 6 is pulled out from the first terminal 10-1 as shown in FIG. 3, the end of the open contact 2-1 comes into contact with the close contact 3 by its elasticity. This also applies to the third terminal 10-3, and when the plug 6 is pulled out from the third terminal 10-3, the end of the open contact 2-2 comes into contact with the close contact 3. Therefore, the plug 6 is pulled out from both the first terminal 10-1 and the third terminal 10-3, and the second terminal 10-2
If another coaxial cable is respectively connected to the fourth terminal 10-4 and the fourth terminal 10-4, the inner conductors of the coaxial cables connected to the second terminal 10-2 and the fourth terminal 10-4 are connected to each other by the open contact 2- 1, 2-2 and closed contact 3
Is conducted through. The second terminal 10-2 and the fourth terminal
The outer conductors of the coaxial cables respectively connected to 10-4 are conducted through the shell 4. That is, the coaxial cables respectively connected to the second terminal 10-2 and the fourth terminal 10-4 are connected. The conduction state at this time is shown in FIG.

Even in this state, the transmission path of the high frequency signal, that is, the periphery of the open contacts 2-1, 2-2 and the closed contact 3 is shielded by the shell 4, and the shell 4 is electrically connected to the outer conductor of each coaxial cable. Therefore, the transmission characteristics of the high frequency signal at the open contacts 2-1, 2-2 and the close contact 3 are almost the same as the transmission characteristics of the coaxial cable. That is, the second terminal 10-2
If the coaxial cable is connected only to the fourth terminal 10-2, the entire connector element E functions as if it is a single coaxial cable, and the coaxial cable connected to the second terminal 10-2. From the viewpoint of the signal transmitted through the cable, the open contact 2-1, and the coaxial cable connected to the fourth terminal 10-4, it is the same as when a single coaxial cable is transmitted.

The plug 6 is removed from both the second terminal 10-2 and the fourth terminal 10-4, and another coaxial cable is attached to the first terminal 10-1 and the third terminal 10-3. When they are respectively connected, the internal conductors of the coaxial cables respectively connected to the first terminal 10-1 and the third terminal 10-3 are not connected to any of them and are in an open state. The conduction state at this time is shown in FIG.
