Abstract

PURPOSE:To simply correspond to a change in a signal, by providing a selecting circuit for selecting a connecting pin, an output pin for connecting the output of the circuit, and a control terminal for inputting control signals for determining the connections of the connecting pin and the output pin to the selecting circuit. CONSTITUTION:An interface signal 2 is connected to a programmable connector 1 by a connecting pin 3, and is input to an output pin 5 via a selecting circuit 4. But, when the signal 2 is changed, the connection of the connecting pin 3 to the output pin 5 is changed accordingly by transferring a signal to a control terminal 6, so that the connector 1 is varied in its function. Thus, the connector is varied in its function so that it can correspond to a change in the interface signal without changing the connector and/or the interface cable.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to connectors.

[Conventional technology]

With conventional connectors, only certain signals can be output from the output pins connected to the interface signals.

[Problem to be solved by the invention]

With the conventional connector described above, when an interface signal is changed, it is necessary to change the connector again to match the signal, which is inconvenient. Particularly when connecting various interface devices, changing the interface signal requires changing the interface cable, changing the connector of the host device, or installing an extra connector.

[Means to solve the problem]

The programmable connector of the present invention has a connection pin connected to an interface signal, a selection circuit that selects the connection pin, an output pin that connects the output of the selection circuit, and a control signal that determines the connection between the connection pin and the output pin. and a control terminal input to the selection circuit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram showing one embodiment of the present invention. In the figure, a programmable connector 1 receives input interface signals 2. Connection pin 3 for connecting interface signal 2. Selection circuit 41 for selecting connection pin 3 Output pin 5 for connecting the output from selection circuit 4. It consists of a control terminal 6 for programming which of the connection pins 3 is transmitted to which of the output pins 5.

The interface signal 2 is connected to the programmable connector 1 through a connecting pin 3, passes through a selection circuit 4, and is outputted to an output pin 5. Normally, connection pin 3 is output as is to output pin 5, but when interface signal 2 is changed, the connection of connection pin 3 to output pin 5 is changed by adding a signal to control terminal 6, and the programmable connector Change function 1. This eliminates the need to change connectors or change interface signals.

〔Effect of the invention〕

As explained above, the present invention has the advantage that when there is a change in the interface signal, it can be handled by changing the connector function without changing the connector or the interface cable.
