INDUSTRIAL APPLICABILITY The present invention is used in a block in which a terminal accommodating chamber for accommodating terminal fittings is integrally formed in a frame, and distinguishes between the terminal accommodating chamber in the frame and parts other than the terminal accommodating chamber. To an identification device for doing.

[0002]

2. Description of the Related Art FIG. 11 shows a junction block (hereinafter simply referred to as "block") 1 mounted on a vehicle or the like for branching or connecting. The block 1 includes a frame body 18 and a relay 3 supported by the frame body 18.
The terminal accommodating portion 7 (the hatched portion in FIG. 11) in which the fuse 5 and the fuse 5 are mounted, and the reinforcing rib 9 between the frame 18 and the terminal accommodating portion 7.
And are integrally formed.

The terminal accommodating portion 7 is formed with a plurality of terminal accommodating chambers 15 penetrating the front and back. Flexible locking arms (not shown) project from the inner wall of these terminal accommodating chambers 15 and engage with the engaging shoulders 13a of the female terminal fittings 13 inserted into the terminal accommodating chambers 15. The female terminal fitting 13
Is caulked and connected to the end of the electric wire 11.

Further, the opening on the side opposite to the opening of the terminal accommodating chamber 15 into which the female terminal fitting 13 is inserted (the lower surface side in FIG. 11).
Is a terminal (male terminal) 3a of the relay 3 or the fuse 5,
5a is inserted and fitted into the female terminal metal fitting 13 previously housed in the terminal housing chamber 15 to be electrically connected.

In the block 1 having the above structure, first, the female terminal fitting 13 is inserted into the terminal accommodating chamber 15 in the frame 18, and is held in the terminal accommodating chamber 15 by the flexible locking arm (not shown). At this time, the operator visually confirms the position of the terminal accommodating chamber 15 and inserts the female terminal metal fitting 13 into the terminal accommodating chamber 15.

With the female terminal fitting 13 inserted in the terminal accommodating chamber 15, the terminals 3a and 5 of the relay 3 and the fuse 5 are inserted.
a is inserted into the terminal accommodating chamber 15, fitted into the female terminal fitting 13 and electrically connected.

[0007]

However, since the block 1 is downsized due to space saving, the space between the terminal accommodating portion 7 and the frame 18 becomes narrower, and the opening of the terminal accommodating chamber 15 becomes smaller.
It is difficult to distinguish the portion other than the terminal accommodating chamber 15, that is, the opening 10 formed by the reinforcing rib 9, and the female terminal fitting 13 may be mistakenly inserted into the opening 10 other than the terminal accommodating chamber 15. Therefore, the workability of inserting the terminal fitting into the terminal accommodating chamber 15 is poor.

Further, a terminal accommodating chamber 15 of another type is formed in the block 1 for mounting other types of parts such as the relay 3 and the fuse 5 on the block 1. For this reason, it is difficult to distinguish the terminal accommodating chambers 15 from each other, so that different types of female terminal fittings 13 may be inserted into the terminal accommodating chamber 15.

Further, there is a possibility that the female terminal fitting 13 may be inserted into the terminal accommodating chamber 15 in different directions (positions rotated by 180 degrees with respect to the regular insertion direction).

Therefore, the identification of the terminal accommodating chamber 15 into which the female terminal fitting 13 should be inserted, the insertion direction of the female terminal fitting 13 into the terminal accommodating chamber 15, and the female terminal fitting 13 to be inserted into the terminal accommodating chamber 15. It is difficult to identify the type of
There is a case where the terminal fitting is erroneously inserted into the housing 5 as described above, and in this case, there is a problem that the relay and the fuse cannot be branched and wired in a predetermined manner.

Therefore, in Japanese Utility Model Laid-Open No. 60-164780, a connector wiring jig having information (identification information) for inserting the terminal fitting into the terminal accommodating chamber is arranged around the opening position of the terminal accommodating chamber. A device for doing so has been proposed. According to this device, a predetermined terminal fitting can be inserted into the terminal accommodating chamber by checking the insertion information around the opening position of the terminal accommodating chamber.

However, in the device proposed in the above publication, if the jig for connector wiring is displaced with respect to the connector, incorrect insertion information will be located around the terminal accommodating chamber, and You will end up arranging. Moreover, since the identification information is located adjacent to the terminal accommodating chamber, there is a risk that a different terminal fitting may be mistakenly inserted into the terminal accommodating chamber. Therefore, there is a possibility that the terminal fitting cannot be accurately inserted into the terminal accommodating chamber.

Further, in Japanese Utility Model Laid-Open No. 64-27668, a probe at one end of a detector is inserted into a terminal accommodating chamber, and it is determined whether the terminal fitting is properly inserted depending on the displacement of the probe when the terminal fitting is inserted. There has been proposed a device for electrically detecting such a phenomenon. According to this device, if the terminal is not a proper terminal fitting, or if it is inserted in the wrong insertion direction, this is detected.

However, this device cannot detect whether the inserted terminal fitting is a proper terminal fitting or is inserted in the wrong insertion direction unless the terminal fitting is inserted into the terminal accommodating chamber. That is, although the identification can be made as a result, the terminal fitting cannot be inserted into the terminal accommodating chamber after the insertion information is confirmed in advance. If the terminal fitting inserted in the terminal accommodating chamber is incorrect or is inserted in the wrong direction, pull it out of the terminal accommodating chamber and insert it again into another terminal fitting Since it has to be inserted in the direction, there is a problem that the work is troublesome and the workability is poor.

Therefore, according to the present invention, the terminal accommodating chamber and the portion other than the terminal accommodating chamber can be easily and accurately discriminated, and the workability of inserting the terminal fitting into the terminal accommodating chamber can be improved. Further, it is an object of the present invention to provide an identification device capable of accurately inserting the terminal fitting into the terminal accommodating chamber.

An identifying part that is inserted into the terminal accommodating chamber with the tip end exposed from the opening of the terminal accommodating chamber into which is inserted, and is lowered from the opening of the terminal accommodating chamber by inserting the terminal fitting into the terminal accommodating chamber, and the identifying part. And a supporting means for supporting.

[0017]

According to the first aspect of the present invention, the identification portion supported by the supporting means is inserted into the terminal accommodating chamber inside the frame so that its tip is exposed through the opening. Thereby, the identification information of the terminal fitting in the terminal accommodating chamber is displayed on the opening of the terminal accommodating chamber by the display means. Then, when inserting the terminal fitting into the terminal accommodating chamber, the operator confirms the display means at the tip of the identification section and inserts the terminal fitting based on the identification information into the terminal accommodating compartment.
