Description

  The present invention relates to an adapter, and more particularly to an adapter that is highly efficient when a plurality of types of electrical devices having different types of receptacles and insertion ports are connected by a cord.

  Conventionally, optical terminal and other communication devices installed at electric power companies, etc. are electrically connected by inserting a dedicated cord for measurement, such as an armor cord, into the device side and the test panel side when measuring levels, for example. The measurement is done by doing. This ammunition cord has a connector part shape that differs depending on the model corresponding to each manufacturer and communication device, and is roughly divided into three types. Depending on the case, there are also codes having different shapes at both ends.

  Specifically, there are mainly three types of connector shapes as shown in FIGS. 6 (a), (b), and (c). In these examples, the receiving port corresponding to the insertion port is determined. In the example shown in FIG. 6, only the insertion port 1 can be inserted into the receiving port A, and only the insertion port 2 can be inserted into the receiving port B. Only the insertion port 3 can be inserted into C.

  Here, the receiving port A and the insertion port 1 shown in FIG. FIG. 7 shows (a) before insertion of the insertion port 1 with respect to the reception port A, during insertion (b; however, only the receiving terminal 10 and the insertion terminal 20 are shown), and connection completed (C; however, the receiving terminal). 10 and only the plug-in terminal 20 are shown). First, by inserting the insertion terminal 20 that becomes the conductive portion of the insertion port 1 into the reception terminal 10 that becomes the conductive portion of the reception port A, the reception terminal 10 that is normally connected opens, and the reception port A Contact is made before the circuit on the side is disconnected, and the circuit on the side of the receptacle A is electrically connected via the insertion terminal 20 by further insertion after contact (during insertion). And the whole convex part of the insertion terminal 20 is fitted by the bottom face of the recessed part of the receiving terminal 10. FIG. Thereby, each terminal of the receiving terminal 10 has a contact with each corresponding terminal of the insertion terminal 20, and for example, a connection is made from a terminal at one end of the receiving terminal 10 via a terminal at one end of the insertion terminal 20. Through the meter 30, the other end of the plug-in terminal 20 is electrically connected to the other end of the receiving terminal 10 (connection complete).

  As described above, since there are several types of ammunition (connector portion) at present, for example, when measuring some value of a communication device with a test board, the communication device and the test board are securely fitted. There was a problem that it was necessary to prepare the ammunition cord for each type of the above-mentioned ammunition, and it took time to prepare for the work. In other words, it is necessary to select the ammunition cord reliably and quickly and perform the work. Along with this, there was a management problem that several types of ammunition codes had to be managed and stored.

  Moreover, as a technique related to the connector, for example, as a connector having excellent workability, a connector capable of fitting a large number of stacked connectors together with a mating connector is disclosed (see Patent Document 1). However, it is not considered in the above situation because it does not consider a configuration for improving workability when electrically connecting to apparatuses having different shapes.
