Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit unit for intermediate coupling between connector elements which cannot be directly connected among a plurality of sets of connectors each of which is composed of a connector element such as a plug or a jack for receiving the plug. ,
For example, it is used for wiring of a duplexer, a triplexer, a SWR meter (which measures matching with an antenna), a radio device, and the like.

[0002]

2. Description of the Related Art Generally, when connecting distant circuit units in a communication system or the like, a coaxial cable having a connector element such as a plug or a jack at each end is used.

These connector elements are shown in FIG.
As shown in (b) and (c), M
There are a plurality of types such as type, N type, and BNC type which have different shapes and characteristics (frequency characteristics) according to the size of the diameter of the cable.

These several types of connector elements cannot be connected to different types. For example, for an M-type Bragg-shaped terminal 10 provided in the duplexer (circuit unit) main body 1, an M-type jack 11 and an N-type connector element are used. Plug-shaped terminal 10
a is an N-type jack 11a, and a BNC-type plug-shaped terminal 10b is a BNC-type jack 11b.
Only each can be connected.

In the conventional duplexer (circuit unit), the terminals 10, 10a, 1 determined at the time of manufacture are provided.
0b is integrated with the duplexer (circuit unit) body 1. Therefore, this terminal 1
If 0, 10a, 10b and the connector elements (jacks 11, 11a, 11b) of the coaxial cable are not of the same type but of different types, direct connection is impossible.

In such a case, the circuit unit itself or the coaxial cable itself is exchanged so that both types are the same, or, as shown in FIG.
And a connecting portion 14 that can be connected to the jack 13 respectively
By interposing the conversion connector 14 provided with a and 14b and coupling them, the conversion connector 14 is provided between the two.
I am trying to communicate through.

Further, as a means for connecting between connector elements that cannot be connected, there is one disclosed in Japanese Utility Model Laid-Open No. 3-64490. This is one in which a connector portion corresponding to a connector element is appropriately selected and a wire is provided between the selected connector portions.

[0008]

As described above, since the above-mentioned conventional circuit unit has terminals integrally formed, it is possible to change various circuit units or change the type of connector element to be connected. If it happens, the circuit unit currently in use will be disabled unless the conversion connector is used. Therefore, when the circuit unit has a plurality of terminals, a situation may occur in which the circuit unit itself cannot be used because one terminal cannot be connected.

In response to this, as one terminal, for example, three types of terminals 10, 10 as shown in FIG.
Although a plurality of circuit units each having a and 10b are provided, in a circuit unit with a large number of terminals, the number of combinations of types of connector elements to be connected also increases, and it is costly to manufacture all of them. Was also unreasonable.

Also, in the method of connecting using the conversion connector 14 shown in FIG.
Since a and 14b are integrated, the number of combinations of the terminals and the connector elements of the coaxial cable is required in the same manner as described above, which is also unreasonable in terms of manufacturing cost.

Moreover, since terminals and connector elements are respectively attached to the conversion connector 14, the portion which cannot be bent at the end of the connection is made longer than the ordinary connection portion, and especially when the system is installed, this If the connecting portion is located, for example, at a corner of a pillar or the like in a room or unevenness in a vehicle, it may not be possible to flexibly cope with it and inconvenience may occur in proper system installation.

Further, in the data communication repeater disclosed in Japanese Utility Model Laid-Open No. 3-64490, a wiring hole for connecting a lead wire is formed in the wiring portion which is the other coupling portion different from the connector portion. Is determined according to the number of pins in the connector section, and the shape of the wiring section as a whole differs for each connector section (the number of pins), so the wiring work tends to be troublesome. Have

According to the present invention, the intermediate coupling circuit unit includes:
An intermediate coupling circuit unit and various connectors are formed through a connector coupling member having a common coupling portion that can be coupled to the coupled portion by forming a coupled portion having a shape that does not depend on the type of the connector element of the connection partner. By making it possible to connect elements, it is an object to simplify the connecting operation between connector elements that cannot be directly connected.

Another object of the present invention is to enhance the convenience of the intermediate coupling circuit unit by providing a plurality of coupled parts on the input side or the output side of the intermediate coupling circuit unit.

Further, by providing a predetermined circuit portion between the coupled portion on the input side and that on the output side, not only the connection between arbitrary connector elements but also the electric signal sent between these connector elements is provided. The purpose is to perform circuit processing such as distribution and frequency discrimination.

[0016]

The intermediate coupling circuit unit of the present invention is a connector element which cannot be directly connected in a plurality of sets of connectors each of which is composed of a connector element such as a plug or a jack for receiving the plug. In an intermediate coupling circuit unit used for connecting to each other, formed on the other coupling portion of each connector coupling member in which a connector coupling portion having a shape capable of coupling with the connector element is formed on one coupling portion. The coupled parts (2, 2a, 2b) that can be coupled to the common coupling part having the same shape are formed on the input side and the output side by arranging a plurality of them on at least one of them, and A predetermined circuit portion is provided between the coupled portion and that on the output side.

[0017]

The coupled portion of the circuit unit for intermediate coupling and the common coupling portion of the connector coupling member are made detachable by using, for example, screw coupling, and this connector coupling member is used for all types of connector elements. By preparing only the components, only the connector coupling member that is the connection partner of the coupled portion can be exchanged, and the connector elements of each type can be connected through the connector coupling member.

That is, N sets of connector elements (plugs,
In the case where three coupled parts are formed in the intermediate coupling circuit unit, the connector coupling member for the plug side is 3N, and the connector coupling member for the jack side is 3N, which is 6N in total. Individual pieces are prepared, and any three of them are selected to be used by connecting them to the jointed portion.

Further, since the shape of the coupled portion of the intermediate coupling circuit unit and the shape of the common coupling portion of the connector coupling member are completely unified, the connector coupling member appropriately selected for this coupled portion. The two are integrated by a simple procedure such as attaching the common coupling part of (1), and the intermediate coupling circuit unit having a predetermined coupling portion for each connector element is easily formed.

Further, since the connector coupling member is connected to the jointed portion, the unbendable portion is made smaller than that in the case where the conventional conversion connector is used, and the (bending near the connecting portion is The degree of freedom is increased.
