[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal half-insertion detecting device for inspecting the continuity of a terminal fitting and detecting whether the terminal fitting is inserted into a proper receiving position in a terminal receiving chamber of a connector. The present invention relates to a structure and a connector terminal detector.

[0002]

2. Description of the Related Art FIG. 12 shows a connector 1 described in JP-A-64-54678. In the connector 1, a plurality of terminal accommodating chambers 5 are formed in a housing 3, and in these terminal accommodating chambers 5, terminal fittings 7 crimped to wire terminals (see FIG. 13A). Is housed.
A flexible locking arm (not shown) protrudes from the terminal accommodating chamber 5, and the locking step at the distal end of the locking arm engages with the locking portion of the terminal fitting 7. The terminal fitting is prevented from coming out of the terminal accommodating chamber 5.

[0003] In the housing 3 of the connector 1, a spacer 9 formed separately from the housing 3 is mounted. As shown in FIG. 12, the spacer 9 is provided with a plurality of insertion pins 11, and is inserted into the terminal receiving chamber 5 from a through hole 13 provided in the housing 3. A temporary lock piece 17 and a permanent lock piece 19 are protruded from the insertion pin 11, and as shown in FIG. 13A, the position where the temporary lock piece 17 is As shown in b), the spacer 9 is mounted on the housing 3 at a position where the lock piece 19 is engaged with the housing 3. Each of the insertion pins 11 is provided with a locking projection 21. The locking projection 21 engages with the locking portion 7a of the terminal fitting 7 when the spacer 9 is mounted at the main locking position. As a result, the terminal fitting 7 is doubly locked in the terminal accommodating chamber 5 by the locking arm and the locking projection 21.

[0004] In this connector 1, the terminal fitting 7 can be inserted into the terminal accommodating chamber 5 while the spacer 9 is mounted in the temporary locking position. When the terminal 9 is moved from the temporary lock position to the full lock position, it is engaged with the locking projection 21 to prevent the terminal fitting 7 from coming out of the terminal accommodating chamber 5.

In this connector 1, when the spacer 9 is moved from the temporary lock position to the final lock position after the terminal fitting 7 is accommodated in the terminal accommodation chamber 5, the terminal fitting 7 is partially inserted into the terminal accommodation chamber 5. In this case, the spacer 9 cannot be moved to the full lock position. This makes it possible to detect the state of the terminal fitting 7 being half-inserted into the terminal accommodating chamber 5.

However, after the terminal fitting 7 is accommodated in the terminal accommodating chamber 5, the operation of moving the spacer 9 from the temporary lock position to the final lock position may be forgotten or may not be completely moved. In this case, the terminal fitting 7 cannot be double locked in the terminal accommodating chamber 5. Also, the spacer 9 has not been moved from the temporary lock position to the full lock position,
The terminal fitting may be sent to the terminal fitting continuity inspection step while being partially inserted into the terminal accommodating chamber.

Therefore, a connector terminal detector for checking the continuity of terminal fittings is provided with a mechanism for checking whether or not the spacer is moved to the full lock position.
No. 786 has proposed this.

This connector terminal detector comprises a connector receiving portion for mounting a connector, and a detector main body which is arranged to be able to freely contact and separate from the connector receiving portion. A continuity inspection pin for inspecting is provided. Further, the connector receiving portion is formed with a detecting portion for detecting whether the spacer is at the full lock position or the temporary lock position. The detector allows the detector body to move to the connector receiving side when the spacer is in the full lock position, and allows the detector body to move to the connector receiving side when the spacer is in the temporary lock position. A locking mechanism for blocking is connected.

According to this connector terminal detecting tool, when the connector is mounted on the connector receiving portion and the detector body is moved to the connector receiving portion side, if the spacer is not at the full lock position, the detecting portion detects this. Since the lock mechanism prevents the detector main body from moving toward the connector receiving portion, it is possible to detect that the spacer is at the temporary lock position and the terminal fitting is half inserted into the terminal receiving chamber. This makes it possible to reliably detect that the terminal fitting is half-inserted into the terminal receiving chamber.

[0010]

However, when detecting the half insertion of the terminal fitting into the terminal accommodating chamber, as described above, in the structure for detecting whether or not the spacer has been inserted to the full lock position, the spacer is not used. Since it is necessary, the number of parts constituting the connector is large. In addition, an operation process for attaching the spacer to the connector is required.

Further, in order to confirm whether or not the spacer has been moved to the full lock position, the spacer is mounted on the connector receiving portion of the connector terminal detector and the lock position of the spacer is confirmed. Since it is indirectly detected whether or not the metal fitting is half-inserted, there is a problem that it takes time to detect half-insertion of the terminal fitting into the terminal accommodating chamber.
