Description

[Detailed Description of the Invention] [Structure of the Invention] (Industrial Application Field) The present invention relates to a branch connector for relaying and branching two-core coaxial cables, and specifically relates to a branch connector and a relay using the branch connector. Concerning branching methods.

(Prior Art) Conventionally, for example, in a distributed processing system, two-core coaxial cables are connected to two-core coaxial cables Ila and Ilb with connectors 12a and 12a, respectively, as shown in FIG.
12b and the connector 12a.

12b with adapter I3.

In other words, the relay is performed using two connectors and one adapter. These two connectors and one adapter are called a relay connector. However, since such a relay connector is a two-point connection, for example, terminal 1 shown in FIG.
When branching a 2-core coaxial cable due to the addition of 4, etc.,
Two sets must be used.

Therefore, in conventional relay connectors, the number of parts increases when branching a two-core coaxial cable, and work is required to insulate the relay connector and solder the parts that make up the relay connector, which is laborious. There was a drawback that it took a while.

(Issue 8 to be solved by the invention) As mentioned above, since conventional relay connectors connect at two points, two sets are required when branching a two-core coaxial cable, increasing the number of parts. Insulation and soldering required work and had the disadvantage of being time-consuming.

The present invention was made in view of the above points, and an object thereof is to provide a branch connector and a relay branching method using the branch connector, which can relay and branch two-core coaxial cables with one set and with simple work. shall be.

[Structure of the Invention] (Means for Solving the Problems) That is, the branch connector according to the present invention includes a jack and a plug. The jack has at least one pin receiver formed by first and second contact pieces extending from the first and second terminals, respectively, in contact with each other in a separable manner. Further, the plug has at least one pin connected to H and is detachably installed in the jack.

The pin is provided facing the pin receiver, and has third terminals extending from the third and fourth terminals, respectively.

By attaching the plug to the terminal of which the third and fourth cables are connected, respectively, to the pin receiver so that the pin fits, the first and second cables connect to the third and fourth cables, respectively. Connected to the branch cable.

(Embodiment) Hereinafter, a branch connector and a relay branching method using the branch connector according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view showing its configuration, in which the branch connector is a jack 21. It is composed of a plug 22 and a cover 23. The jack 21 is provided with a connecting portion 24 for relaying and connecting two two-core coaxial cables. This connection portion 24 includes a set of three terminals 25, 26 and each terminal 25.
．． It consists of contact pieces 27, 28 extending from 26. Two core wires and a shield wire of a two-core coaxial cable are connected to the terminals 25 and 26, respectively.

Further, the contact pieces 27 and 28 are formed of, for example, a conductive spring plate, and contact each other so as to be able to separate from each other to form a pin receiver 29. In addition, terminals 25, 26 and contact pieces 27, 28
is fixed to the connecting portion 24 by screwing or the like without requiring soldering.

The plug 22 is detachably installed in the jack 21, and when attached to the jack 21, serves as a connection for branching and connecting two two-core coaxial cables that are relay-connected by the same jack 21 to other two-core coaxial cables. It has a section 30. The connecting portion 30 consists of a set of three terminals 31.32 and contact pieces 33.34 extending from each terminal 31.32.

Two core wires and a shield wire of a two-core coaxial cable are connected to the terminals 31 and 32, respectively.

The contact pieces 33 and 34 are made of conductive plates and are connected to the insulating member 3.
5, which are integrally formed in a non-contact manner and fit into the pin receiver 29 of the jack 21 to connect the contact pieces 27 and 28, respectively.
It constitutes a pin 36 which is brought into contact with the contact pieces 33, 34.

Note that the terminal 3L 32 and the contact pieces 33, 34 are fixed to the connecting portion 30 by screws or the like without requiring soldering.

Further, the cover 23 serves as a lid that covers the top of the plug 22. Note that the jack 21, plug 22, and cover 23 are
Each is made of an insulating material and is integrated with screws or the like.

Next, a relay branching method using the branching connector configured as described above will be explained.

First, when connecting a two-core coaxial cable via relay, only the jack 21 is used as shown in FIG.

The jack 21 is connected to four input/output ports A to D. At this time, the contact piece 27.2 extended from the terminal
8 is in contact. Therefore, the two two-core coaxial cables connected to the terminals t and d are connected to the contact piece 2.
It is electrically connected through 7.2B.

FIG. 2 shows two opposing input/output ports in the jack 21, for example, input/output port A and input/output port B1 or input/output port C.
This is a diagram in which two two-core coaxial cables are relay-connected using an input/output port, and signals flow in both directions as shown by arrow a through a jack 21.

In the example shown in Figure 2, two opposing input/output ports are used, but depending on the wiring design, input/output port A and input/output port C1, or input/output port B and input/output port, etc., are used. Relay connections can also be made using adjacent input/output ports.

On the other hand, when branching and connecting a two-core coaxial cable, a jack 21 and a plug 22 are used as shown in FIG. The plug 22 is provided with two adjacent input/output ports E1F, and using these input/output ports E and F, one end can be connected to a branch destination,
For example, two two-core coaxial cables connected to the terminal 41 are connected to the terminals 31 and 32 of the connection part 30. At this time, the contact pieces 33.34 extending from the terminals 31.32 are in a non-contact state with the insulating member 35 interposed therebetween. Therefore, the two two-core coaxial cables each connected to the terminal 3L 32 are not electrically connected.

Then, jack 2 connects two 2-core coaxial cables.
1, the plug 22 is attached to the jack 21 so that the pin 3B of the plug 22 fits into the pin receiver 29 of the jack 21. When the pin 3G is fitted into the pin receiver 29, the contact pieces 33.3 of the jack 21 forming the pin receiver 29 are separated, and the contact pieces 33.3 of the plug 22 forming the pin 36 are separated.
Contact 4. As a result, the two two-core coaxial cables connected by the jack 21 are branched and connected to separate two-core coaxial cables.

FIG. 3 is a diagram in which two two-core coaxial cables connected to the jack 21 are branched and connected to a terminal 41 by attaching a plug 22 to the jack 21, and signals are transmitted through the terminal 41 by arrows 1 and 2. flows in both directions, as in

In addition, in the example of FIG.
Although the two-core coaxial cable connected using one input/output port is branch-connected, it goes without saying that the two-core coaxial cable connected using the other two input/output ports of the jack 21 is branch-connected. It is also possible.

In this way, the branch connector of the present invention has a relay function with the jack 21 alone, and has a branch function by attaching the plug 22 to the jack 21. Therefore, if you install only the jack 21 in advance at the location where you plan to add a terminal and wire the 2-core coaxial cable, you can connect the 2-core coaxial cable to the terminal by simply attaching the plug 22 to the jack 21 when adding a terminal. Can be connected to a branch. In this case, the cover 23 is used to integrate the jack 21 and the plug 22, but since the jack 21, plug 22, and cover 23 are insulating parts, and can be easily integrated with screws, etc., the conventional relay connector No work is required for insulation and soldering.

In addition, while the conventional relay connector has a two-point connection, the branch connector of the present invention has a four-point connection by attaching the plug 22 to the jack 21, so one set can relay and connect two-core coaxial cables. Branch connections can be made, which reduces the number of parts, lowers costs, and enables highly expandable wiring design.

Furthermore, when installing multiple terminals, it is necessary to install a terminal equipped with a terminator (terminal resistor) at the end, but with the branch connector of the present invention, the terminator can be stored inside the branch connector. (In this case, a terminator is provided between the two core wires of the two-core coaxial cable connected to the jack 21.) This allows multiple identical terminals to be installed regardless of the termination.

[Effects of the Invention] As described above, according to the present invention, the two-core coaxial cable is relay-connected by using only a jack, and the two-core coaxial cable is branch-connected by attaching a plug to the jack. Two-core coaxial cables can be relayed and branched with one set and with simple work.
