SUMMARY OF THE INVENTION The conventional cable checker as described above is an adapter cable for connecting the corresponding adapter connector to the inspection circuit according to the connector (receptacle or connector plug) at both ends of the inspection cable. Since it is attached, only a person with specialized knowledge can create an adapter, and in order to support a wide variety of cables, many types of adapter cables are required, and the production cost is high. There was a problem of becoming.

In view of the conventional problems described above, the present invention provides a cable checker in which an adapter for connecting an inspection cable can be easily manufactured, and an adapter for a large number of cables can be manufactured with a small number of parts. It was made for the purpose of.

[0007]

The feature of the present invention for solving the above-mentioned conventional problems is to provide a connector-equipped cable having a plurality of lead wires and connecting both ends of each lead wire to a connector. In a cable checker that fits both connectors into an adapter connector that is connected to an inspection circuit respectively, and inspects the connection state of the cable with connector, a pair of adapter boards is detachably attached to a support frame. The board is provided with an adapter connector through hole at one end side and a test circuit connection connector through hole at the other end side, and the adapter connector through hole is provided on either or both of the front and back sides of the adapter board. And a printed wiring pattern for electrically connecting the corresponding through holes for inspection circuit connection. A connector for fitting into a connector connected to an end of a cable with a connector to be inspected is attached to the through hole for the adapter, and the supporting frame is provided in the through hole for the inspection circuit connecting connector. The circuit connecting connector that fits into the inspection circuit connector fixed to is attached.

[0008]

In the cable checker of the present invention, for example, when one of the connectors at both ends of the connector-equipped cable to be inspected is the receptacle and the other is the connector plug, these are fitted to the pair of adapter boards. The connector plug and the receptacle are mounted on the outer surface side. At this time, the connector plug is mounted on the front surface side of one adapter board and the receptacle is mounted on the rear surface side of the other adapter board. By using the same shape for both adapter boards with the front and back reversed, the connection state of the adapter connector of both boards to the inspection circuit becomes the same.

A through-hole 13, 13 ... To which a 64-pin connector for inspection circuit connection can be connected by soldering is opened at one edge of the adapter board. Further, both through holes 12 and 13 are provided on both front and back surfaces a and b of the adapter board.
The same patterns 14a and 14b for connecting the two are printed and wired.

On the other hand, in the casing 10, as shown in FIG. 4, a pair of inspection circuit connecting connector sockets 15A, 15A, 15B and 15B are provided so as to face under both sides of the adapter boards 11A and 11B. Is fixed, and the connector sockets 15A, 15A on this one side
Is connected to a terminal on one side of the inspection circuit, and the connector sockets 15B and 15B on the other side are connected to terminals on the other side of the inspection circuit.

As an example, the cable checker of the present embodiment inspects a cable 16 with a connector in which a 25-pin receptacle 16A is connected to one end side and a 25-pin connector plug 16B having a shape fitting with the receptacle 16A is connected to the other end side. One adapter board 11A is provided with a connector plug 17A for an adapter, which is fitted to the receptacle 16A of the cable with a connector to be inspected on the board surface a side, through holes 12, 12 ... , And is connected and fixed to one end side of the through hole row. On the other hand, the other adapter board 11B has an adapter receptacle 17 on the back side b of the board, which is fitted to the connector plug 16B of the inspection cable.
B is biased to the same side as the adapter connector plug 17A in the through holes 12, 12, ...

Further, 64 is connected to the through holes 13, 13 ... On the rear surface b side of one adapter board 11A.
A pin inspection circuit connecting connector plug 18A is fixed, and a 64-pin inspection circuit connecting connector plug 18B also connected to the through holes 13, 13 ... Is fixed on the surface a side of the other adapter board 11B. There is.

The two adapter boards 11A and 11B, to which the respective connectors are fixed in this manner, are fitted into the mounting positions of the casing 10, respectively. At this time, the inspection circuit connecting connector plugs 18A and 18B are fitted in the inspection circuit connecting connector sockets 15A and 15B at positions facing each other, as shown in FIG.

In this way, the adapter boards 11A, 1
