BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for connection of signal paths, for example, between an antenna and a coaxial cable in a communication system, between coaxial cables, between a coaxial cable and a transmitter / receiver, etc. The present invention relates to a conversion connector element group used for connecting the connector elements that cannot be directly connected among N sets of connectors (N is a positive integer of 2 or more) composed of connector elements such as jacks that receive this.

[0002]

2. Description of the Related Art Generally, in connection between an antenna and a coaxial cable, between coaxial cables, between a coaxial cable and a transmitter / receiver, etc., a conversion connector is used when connector elements provided for each cannot be connected. To connect the two. In the present specification, plugs, jacks, etc. that constitute the connector are referred to as connector elements as necessary.

For the convenience of confirming the shape of the connector element to be connected and holding a plurality of such connectors in a holder or the like, the conversion connector is separated into two connector coupling members so as to be detachable and connectable. Japanese Patent Laid-Open Publication No. 53-50073 has been disclosed in which one having a coupling portion corresponding to the above is appropriately selected and integrated.

However, since male and female screws are coupled to integrate the connector coupling members,
It was necessary to prepare two types of connector coupling members corresponding to one type of connector element, having male threads or female threads, which was disadvantageous in terms of manufacturing cost.

Therefore, the applicant of the present invention is trying to solve such a problem in Japanese Patent Application No. 2-211127 "Conversion connector element group" as shown in FIGS. That is, conventionally, the following are disclosed. The coaxial cable 1 and the coaxial cable 2 are respectively provided with a plug 3 and a jack 4 as connector elements that cannot be connected.

Then, corresponding to each of the 2N connector elements, a connector coupling portion that can be coupled with the connector element is formed at one coupling portion, and the other coupling portion has a common coupling of the same shape. 2N or more connector connecting members as a whole, each of which has a portion formed therein.-Intermediate connecting member having a connected portion that can be connected to the common connecting portion is formed in each of the one and the other connecting portions-At least one type of connector element From the conversion connector element group, which is prepared by preparing two pieces of N connector coupling members each corresponding to, a connector coupling member 5 having a connector coupling portion 5a capable of coupling with the plug 3, a jack 4, a connector coupling member 6 having a connector coupling portion 6a that can be coupled to the intermediate coupling member 8 is selected, and the intermediate coupling member 8 is selected, as shown in FIG. b and the coupled parts 8a and 8b are integrated by screw coupling or the like to form a conversion connector, and subsequently, the plug 3 and the jack 4 are coupled to the connector coupling parts 5a and 6a. I am trying to connect.

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. In this, a connector portion corresponding to each connector element is appropriately selected, and a wire is provided between the selected connector portions to connect them.

[0008]

However, the conversion connector formed by Japanese Patent Application No. 2-211127 "Conversion connector element group" is a combination of two connector coupling members and an intermediate coupling member. Further, since the plug or the jack of the connector element is integrally attached to the conversion connector, the connecting portion is enlarged at the end of the connection.

As a result, as shown in FIG. 3 (a), the non-bendable portion is made longer than the normal connecting portion. Especially when the system is installed, for example, a corner of a pillar in a room or in a vehicle. When this connection portion is located on the unevenness, there is a problem that it may not be able to flexibly cope with it and may cause inconvenience depending on the installation situation of the system.

Further, Japanese Utility Model Publication No. 3-64490 discloses that
A connector portion is provided at one coupling portion of the coupling portion, and a wiring portion having a wiring hole for connecting a lead wire is formed as the other coupling portion. As a result of the wiring holes being determined corresponding to the number of pins of the connector section, the shape of the wiring section as a whole is different for each connector section (the number of pins).

Therefore, there is no arbitrariness in which the lead wire may be connected to any wiring hole in order to secure an appropriate communication state between the connector parts, and the wiring work is performed by the operator with his own knowledge or exclusive use. However, there is a problem that the work becomes troublesome.

Further, Japanese Utility Model Laid-Open No. 3-64490 intends to unify the shapes of the respective wiring parts so that they are connected to each other by a simple procedure using a single lead wire. Instead, the lead wires are exclusively put in the respective wiring holes for wiring, and the connector portions are connected to each other. That is, if the lead wires can be connected, the shape of the wiring portion does not have to be the same.

Therefore, in the present invention, the connection portion which cannot be bent is divided into two so as to be able to flexibly deal with the corners of the column, etc., so that the connection portion by the conversion connector does not interfere with the system installation and the conversion is performed. An object of the present invention is to provide a conversion connector element group capable of performing an assembly work for forming a connector by a simple procedure.

[0014]

According to the conversion connector element group of the present invention, the connector elements cannot be directly connected among N sets of connectors each of which is composed of a connector element such as a plug or a jack for receiving the plug. Corresponding to each of the 2N connector elements, one connecting portion is formed with a connector connecting portion that can be connected to the connector element, and the other connecting portion has the same shape. 2N or more connector coupling members that form a common coupling portion, and one and the other coupling portions each can be coupled to the common coupling portion, and by this coupling, all between the common coupling portion Is formed with a coupled portion to be electrically connected by, for example, a coaxial cable, and has a single and flexible intermediate coupling member.

[0015]

Since the single intermediate connecting member has flexibility, the connecting portion between each connector element is divided into two parts by separating the intermediate connecting member, and the non-bendable portion is formed. The degree of freedom (for bending) in the vicinity of such a connecting portion is increased as compared with the case of concentrating in one place.

The conversion connector element group of the present invention is N
For connector elements (plugs, jacks) in pairs, either between plugs or between jacks, eg,
In the case of considering the connection between plugs 2N plug-side connector coupling member N jack-side connector coupling member N intermediate coupling member 1 total (3N + 1) Plug-side connector coupling member 2N Jack-side connector coupling member 2N Intermediate coupling member One (4N + 1) conversion connector element group is prepared, and any two conversion connector elements are selected Then, each of them is connected to the intermediate connecting member for use.

Furthermore, since the shape of the jointed portion of the intermediate joint member and the shape of the common joint portion of the connector joint member are completely unified, the joint portion of the appropriately selected connector joint member is common to this joint portion. The connector coupling member and the intermediate coupling member are integrated by a simple procedure such as attaching the coupling portion to form a conversion connector for connecting arbitrary connector elements to each other.

In this integrated state, the plug 3 and the connector connecting portion 5a and the jack 4 and the connector connecting portion 6a are connected to each other, whereby the connector 3 and the connector connecting member 5 are connected between the plug 3 and the jack 4. A signal is transmitted between the coaxial cables 1 and 2 by putting them in a communication state via 6 and the intermediate coupling member 7.

Further, other than the illustrated combinations of unconnectable connector elements, there are plugs or jacks. In such a case, however, there is a connector coupling portion having a connector coupling portion capable of coupling with each plug or jack. By appropriately selecting members and attaching each of the connector connecting members to the intermediate connecting member 7, the connector elements can be connected in the same manner as described above.

In the present invention, it is sufficient that the two connector connecting members can be integrated via the intermediate connecting member, and as the connecting method, a simple inserting method or projection other than the screw connecting as shown in the drawing is used. Various known methods such as a method based on the interaction between the guide and the guide portion can be used.

Further, in the intermediate coupling member 7, a coaxial cable 7a (a cable consisting of a central conductor and an external conductor which is insulated from the central conductor and concentrically surrounded) is interposed between the coupled portions 7b and 7c. As an alternative, various known cables can be used, such as a cable in which two conductors are arranged in parallel with a predetermined width. Further, the length of the coaxial cable 7a is appropriately determined according to the situation of use.

[0024]

As described above, the present invention provides a conversion connector for connecting arbitrary connector elements to each other by a simple operation such as attaching a common connecting portion of a predetermined connector connecting member to each of the connected portions of the intermediate connecting member. In addition to being formed, since the intermediate coupling member is single and has flexibility, electrical connection between the connector coupling members is made instantaneously, and the position of each connector element to be connected and the intermediate coupling are achieved. The degree of freedom regarding the installation status of the members can be secured, and the system installation can be flexibly handled.
