Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an erroneous connector insertion prevention structure that prevents erroneous connection when connecting a plurality of connectors with cables integrated by a plurality of continuous boards to corresponding connectors on the device side.

[0002]

[Prior art]

 When connecting multiple devices, etc., with multiple cables, connect the connectors that are respectively fixed to the ends of the multiple cables that extend from one device to the other connectors that are provided on the other device. It is necessary to connect to the corresponding one, but in the past each cable had to be connected to the device side connector individually, so not only was the individual connection work complicated, but it was a mistake. Insertion was easy to occur. For example, in an AV device such as a projector with a computer, if the projector and the control console are far apart, three coaxial signal cables for red, blue, and green are provided for each of the three device side cables. Although it was necessary to make an accurate connection with the connector, it was not easy to connect in a small work space or by groping in the dark, and the error insertion rate was extremely high.

[0003]

[The purpose of the device]

 The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional connection method, and in a structure for connecting a connector fixed to a plurality of cables to a plurality of corresponding connectors, respectively, It is an object of the present invention to provide a connector mis-insertion prevention structure that does not require individual connection and can be easily connected even in a narrow place or a dark place without mis-insertion.

[0004]

[Outline of the device]

 In order to achieve the above object, the present invention has a structure in which connectors fixed to a plurality of cable ends are connected to a connector group fixed to a device side, and the connector group on the cable side is made of an elastic material. The connector is fixed by a single continuous board and the corresponding connectors are colored in the same color.Folding portions formed by folding back the continuous board are provided between the connectors to which the continuous board is fixed. The connector is characterized in that it is arranged, and the arrangement intervals of the connectors forming the connector group on the device side and the cable side are set to be non-equidistant, or the arrangement is made non-linear.

[Example of device]

 Hereinafter, the present invention will be described in detail with reference to the preferred embodiments shown in the accompanying drawings. FIG. 1 (a) is a perspective view of a device and the like for explaining the misinsertion preventing structure of the present invention, and FIG. 1 (b) is a partially enlarged view of the front panel 1a of an AV device 1 such as a projector with a computer. The red connector 2, the blue connector 3, and the green connector 4 are fixed, and the connectors 6, 7, and 8 integrally supported by the misinsertion prevention adapter 5 are collectively attached to the connectors 2, 3, and 4. Then, it is configured to be attached and detached. This adapter 5 is formed by connecting the above-mentioned connectors 6, 7, 8 fixed to the ends of the cables 6a, 7a, 8a, respectively, in parallel by a continuous board 9, and the connector 6 is connected to the connector 2. , The connector 7 is connected to the connector 3, and the connector 8 is connected to the connector 4, respectively. The connectors 2, 3, 4, 6, 7, and 8 are respectively color-coded in red, blue, and green to clearly show the correspondence between the connectors.

With this configuration, when connecting the cables 6a, 7a, 8a to the connectors 2, 3, 4 on the device side, the continuous board 9 of the adapter is held and each connector is held. It is only necessary to insert the connectors 6, 7 and 8 into the connectors 2, 3 and 4 with one touch, which not only improves the attachment / detachment operability but also eliminates the possibility of erroneous insertion.

If a resin such as plastic, hard rubber, or the like is used as the material of the continuous board 9, not only the cost is low, but also the flexibility is high and the operability of attachment / detachment is improved. Of course, one of the device side connector and the cable side connector is male and the other is female.

Next, FIG. 2 shows another embodiment of the adapter of the present invention, in which the connecting board portion located between the connectors is folded back to the cable side to form the folded portion 10, and the gap between the connectors is formed. It is characterized in that it can be expanded and contracted. That is, if the distance between the connectors in the device-side connector group and the distance between the connectors in the cable-side connector group are both fixed, the distance between the two connectors may differ due to accuracy errors during manufacturing. However, according to this embodiment, the gap between the connectors on the cable side can be easily fine-tuned at the folded portion 10, so that this gap can be absorbed and an accurate connection can be made. It becomes possible.

In each of the above-described embodiments, an example in which the device-side and cable-side connectors are arranged in a straight line at equal intervals has been shown. There is a possibility that it will be connected as it is. For this reason, as shown in FIG. 3, if the connectors that make up each connector group are arranged at different intervals or arranged in a non-linear manner so that connections can be made only from one direction, erroneous connections will occur. Can be prevented. Further, a configuration in which the embodiment of FIG. 2 and the embodiment of FIG. 3 are combined is also included in the present invention.

The present invention is not limited to the example shown in the above embodiment, and is generally applicable to the case of connecting two sets of connector groups.

[0011]

[Effect of device]

 As described above, according to the present invention, the connectors at the plurality of cable end portions are fixed to one continuous board, and each connector can be identified by a method such as color coding. It is possible to prevent erroneous connection when connecting to the connector and to connect a plurality of cables at once, so that connection work in a narrow work space, a dark place, etc. can be made easy and reliable.
