2. Description of the Related Art Japanese Unexamined Patent Publication No. 4-137474 can be cited as a prior art document of a double locking type connector.

FIGS. 9 and 10 show a conventional technique. The connector 20 includes an insulating housing 22, a double locking member 24, and a plurality of contacts 26 (only one is shown). The insulating housing 22 has an insertion hole 30 of the contact 26 at one end (contact insertion side) 28 and a contact (not shown) of a mating connector at the other end (mating side) 32.
Are formed in upper and lower two stages, respectively.
Each of the insertion holes 30 and 34 is provided in the corresponding contact accommodation room 3.
6, 36 '. The insulating housing 22
A single large opening 40 for receiving the double locking member 24 is provided in the side wall 38 of the plurality of contact receiving chambers 36,
It is formed across 36 '. Double locking member 24
Is generally formed of a synthetic resin and has a base 42 continuous in the longitudinal direction, a partition 44 extending from the base 42 at predetermined intervals,
And the insertion end 4 where the ends of the partition 44 are interconnected.
6. The base 42, the partition 44, and the insertion end 46 form a plurality of contact insertion holes 4 arranged in a line.
8 is formed, and communicates with the lower contact housing 36 of the insulating housing 22 at a temporary locking position of the double locking member 24 described later. First locking projections 52, 52 that lock into concave portions 50, 50 (only one is shown) formed on the inner wall surface of the opening 40 of the insulating housing 22 are provided at both longitudinal ends of the base portion 42 of the double locking member 24. Is provided. In addition, a second engagement member that is engaged with the inner wall 54 of the contact housing chamber 36 of the insulating housing 22 is provided on the rear end side of the base 42 (the mating contact insertion port side is the front end side and the contact insertion port side is the rear end side). Stop projections 56, 56 are provided.

The double locking member 24 inserted into the opening 40 of the insulating housing 22 locks the first locking projections 52, 52 into recesses 50, 50 provided on the inner wall surface of the opening 40. Temporarily lock to the insulating housing 22. In this temporary locking state, the contact insertion hole 48 of the double locking member 24 communicates with the lower contact housing chamber 38. Further, since the insertion end 46 of the double locking member 24 is at a position where the advancement of the upper contact 26 ′ is not hindered, the contacts 26, 26 ′ are inserted into the contact receiving chambers 36, 36 ′ from the contact insertion opening 30. can do. The inserted contacts 26, 26 'engage with housing lances 58, 58' extending from the inner wall of the insulating housing 22 into the contact accommodating chambers 36, 36 'and engaging holes 26a, 26a' of the contacts 26, 26 '. To perform primary locking.

After all the contacts 26 and 26 ′ are primarily locked, when the double locking member 24 is further pushed into the opening 40, the second locking projection 56 is moved to the lower contact housing chamber of the insulating housing 22. By engaging with inner wall 54 of 26,
The double locking member 24 is fully locked to the insulating housing 22. In this fully locked state, the engagement portions 60, 60 'at the front end of the double locking member 24 are engaged with the rear ends of the contact portions 26b, 26b' of the contacts 26, 26 'with the mating contacts. , And the contacts 26, 26 'are secondarily locked. The contacts 26, 26 'are
8, 58 'and the engaging portions 60, 60' of the double locking member 24.
Are double-locked by the
This ensures that the contacts 26, 26 'are prevented from coming off from the rear.

In order to remove the double locking member 24 from the insulating housing 22, the hole 6 adjacent to the second locking projection 56 is required.
2 can be removed by inserting a tool such as a screwdriver.

[Problem to be solved by the invention] As described above,
Since the connector of the related art has a structure including an insulating housing having a contact housing chamber and a double locking member housed in a shape crossing the contact housing chamber, an opening crossing the contact housing chamber of the insulating housing is provided. Since the mold is formed, the mold is generally composed of a slide core having a contact accommodation hole and a core pin inserted into the contact accommodation hole of the slide core. Burrs are likely to be formed on the bent portion (opening of the insulating housing), which may hinder contact insertion. Further, in the process of inserting the contact, two steps are required, and when the contact is inserted and removed, it is easy to be caught, which hinders the harness work.

The present invention is intended to eliminate the drawbacks of the conventional connector, to simplify the manufacturing process using a mold, and to provide a connector with improved harness workability when inserting and removing a contact. Things.
