DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a divided assembly type connector in which a plurality of sub-connectors are assembled in a connector frame, and more particularly, to the reliability of fitting of the sub-connector into the connector frame. The present invention relates to a split-assembly type connector that can easily check the fitted state of a sub-connector in the connector frame while increasing the height.

[0002]

2. Description of the Related Art As a configuration of a conventional split-assembly type connector, a configuration shown in FIGS. 4 and 5 is known. Hereinafter, the configuration of the conventional split-assembly type connector will be described.

[0003] 1A, 1B, 1C, 1D, 1E, 1F are respective sub-connectors. These sub-connectors 1A to 1F are installed in, for example, an automobile via respective wire harnesses (not shown). Connected to each device. The sub connectors 1A to 1F are
They can be collectively housed and fitted in the connector frame 2 and handled as one connector.

The configuration of the connector frame 2 is a housing type having an opening 3 only on the back surface thereof.
A plurality of sub-connectors 1A to 1F can be fitted together inside the connector frame 2. In the front wall 4 of the connector frame 2, a number of connection terminal insertion holes 6 corresponding to the mating terminal insertion holes 5 provided in each of the sub-connectors 1A to 1F fitted in the connector frame 2 are formed. Have been. In the vicinity of the opening 3 on the upper wall outer surface 7 and the lower wall outer surface 8 of the connector frame 2, locking claws 9 and 10 of a cover, which will be described later, protrude.

A cover 11 protects a wire harness (not shown) drawn from each of the sub-connectors 1A to 1F fitted into the connector frame 2 and prevents the sub-connector from falling off. An opening 12 is formed on one side to allow the wire harness to be drawn out of the cover, and a locking claw provided on the connector frame 2 is formed on the outer wall surface 13 and the lower wall surface 14 of the cover. Locking piece 1 locked to 9 and 10
5 and 16 are formed.

A support shaft 18 protrudes from the center of the upper wall outer surface 7 and the lower wall outer surface 8 of the connector frame 2.
The lever 19 has a shaft hole 19 that is supported by the lever 19. The lever 19 engages a projection formed on a mating connector frame (not shown) with a cam groove 20 provided on the lever 19. After that, the lever 19 is rotated about the support shaft 18 to maintain the fitting between the connector frame 2 and the mating connector frame 2 (not shown).

[0007]

However, in the conventional split-assembly type connector having such a structure, each sub-connector AF is fitted into the connector frame 2 and then the cover 11 is provided behind the connector frame 2. To complete the assembly of the split set connector,
In the split-assembly type connector having the conventional structure, after each sub-connector 1A to 1F is fitted into the connector frame 2,
When the cover 11 is attached to the rear opening 3 of the connector frame, for example, as shown in FIG. 5, even if any of the sub-connectors (1A in this example) is in a half-fitted state, The cover 1 is inserted into a gap (a) formed between the outer side surface and the inner side surface of the connector frame 2.
1 is fitted into the locking piece 1
The locking of the cover 11 to the connector frame 2 is achieved by locking the locking claws 9 and 10 with the locking claws 9 and 10. That is, even if the sub-connector fitted in the connector frame 2 is in an incompletely fitted state, the cover 11 can be attached to the connector frame 2, so that the cover 11 is attached to the connector frame 2. After the fitting, it was difficult to confirm whether or not each of the sub-connectors 1A to 1F fitted in the connector frame 2 was completely and accurately fitted in the connector frame 2.

That is, in the conventional connector, there is no means for confirming complete fitting of the sub-connectors 1A to 1F fitted in the connector frame 2, and after the sub-connectors 1A to 1F are fitted in the connector frame 2, Since the cover 11 can be attached to the connector frame 2 regardless of whether the sub-connectors 1A to 1F are completely or completely incompletely fitted, the sub-connectors can be attached after the cover 11 is attached to the connector frame 2. It is difficult to confirm the complete fitting of 1A to 1F, and there is a risk of using the connection terminal in an incompletely connected state.

Therefore, in order to avoid the use of the sub-connector in an incompletely fitted state in the connector frame 2 as described above, it is necessary to confirm the fitted state of the sub-connector in the connector frame 2 after assembling the connector. This requires an inspection process for performing the inspection and a dedicated inspection device used for the inspection, so that the assembling workability of the connector and the assembling economy are poor.

The present invention has been made in view of the above-mentioned facts in such a conventional split-assembly type connector. After fitting each sub-connector into a connector frame, and then attaching a cover to the connector frame, the provisional If each sub-connector fitted in the connector frame is incompletely fitted, the cover cannot be completely attached to the connector frame, thereby confirming that the sub-connector in the connector frame is in an incompletely fitted state. If it is possible to know, and if the cover is forcibly attached to the connector frame, the sub-connector that is incompletely fitted can be completely fitted to the proper position of the connector frame. The purpose is to provide.

[0011]

According to a first aspect of the present invention, there is provided a connector frame in which a plurality of sub-connectors to which a wire harness is connected are fitted, and the connector frame is fitted in the connector frame. In a split-assembly type connector having a cover for protecting a wire harness drawn out from each sub-connector and preventing detachment of each sub-connector from a connector frame, at a wire harness draw-out side end of each of the sub-connectors, Pressing projections protruding from the outer surface of the sub-connector are provided,
Further, the cover is brought into contact with a projection provided on each of the sub-connectors by an operation of attaching the cover to the connector frame, and when the cover is completely attached to the connector frame, the inside of the connector frame is removed. The connector is characterized in that it is a split-assembly type connector provided with a sub-connector pushing edge for pushing an incompletely fitted sub-connector to completely fit it into the connector frame.
