Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a joint connector that can ensure fitting of short terminals.

[Background of the idea]

A conventional joint connector has a configuration as shown in FIG. This is divided into a plurality of terminal accommodating chambers 2 by a partition wall 1, and each terminal accommodating chamber 2.
It has a housing 6 which is integrally constructed with a holding lid 12 for preventing detachment of a plurality of short terminals 4 and 5 which are brought into fitting contact with joint terminals 3 inserted therein, When fitting the short terminals 4 and 5, each terminal housing chamber 2
After the short terminals 4 and 5 are fitted so that the contact tongues 7 of the short terminals 3 are in contact with the joint terminals 3 housed inside, the presser cover 12 of the housing 6 is placed on the back of the short terminals 4 and 5, and then A locking claw 8 provided on the edge of the presser cover 12 is locked in a locking hole 9 provided on the side surface of the housing 6 to prevent the short terminals 4 and 5 from coming off. In addition, 10 is an electric wire connected to each joint terminal 3, and 1
1 indicates a thin hinge connecting the presser cover 12.

However, in such a conventional joint connector, inside the housing 6,
Since six types of short terminals 5 and ten types of terminal housing chambers 2 into which four types of short terminals can be inserted are provided, for example, only six types of short terminals 5 can be inserted.
Or, when inserting only four types of short terminals 4 into the terminal accommodating chamber 2 of the housing 6, the short terminal 5 or 4 may be inserted into the terminal accommodating chamber 2 where it should not be inserted due to an insertion error, and the short terminal 4 may be inserted into the terminal accommodating chamber 2 where it should not be inserted. There were problems in that a suitable circuit could not be established and the circuit could be damaged.

[Purpose of invention]

The present invention has been developed by focusing on such conventional problems, and when inserting a short terminal into the terminal accommodating chamber 2 in the housing 6, the inserted short terminal can only be inserted into the regular terminal accommodating chamber. It is an object of the present invention to provide a joint connector that can solve the problems of the conventional example by providing a stepped portion to prevent attachment.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIG. Therefore, the explanation of its structure will be omitted.

That is, in this embodiment, a protrusion 20 is provided on the edge of the short terminal insertion side of the partition wall 1 provided in the housing 6, and the short terminal 5 inserted into each terminal accommodating chamber 2 in the housing is provided with a protrusion 20. ,
When the short terminal 5 is inserted into the proper position of each terminal accommodating chamber 2, a notch 21 is formed to avoid contact with the protrusion 20.

In this way, the housing 6 is provided with the protrusion 20, and the short terminal 5 is provided with a protrusion 20 to avoid contact with the protrusion 20 when the short terminal 5 is inserted into the housing 6 at its proper position. The short terminal 5 is configured so that the short terminal 5 can be reliably installed into the housing 6, and if the short terminal 5 is not inserted into the proper position of the housing 6, the protrusion 20 Since the short terminal 5 is not securely inserted into the housing 6 due to contact with the short terminal 5, the presser cover 12 is not attached, and therefore the short terminal 5 is not inserted in the correct position. It's starting to become clear.

Therefore, according to this embodiment, the presser cover 12 is not attached unless the short terminal 5 is inserted into the proper terminal accommodating chamber 2 of the housing 6, so there is no possibility of correct or incorrect insertion position of the short terminal 5. This makes it easy to determine whether or not a proper circuit is established by connecting the short terminals 5, which has the effect of providing a highly reliable joint connector.

In the above embodiment, the housing 6 has the protrusion 2.
0, and a notch 21 was provided on the short terminal 5 to avoid engagement with the protrusion 20.However, conversely, a protrusion having the same effect as the protrusion 20 was provided on the short terminal 5, and a cutout 21 was provided on the short terminal 5 to avoid engagement with the protrusion 20. A notch that can avoid contact may be provided in the partition wall 1 of the joint connector.

[Summary of the idea]

As described above, the present invention has a plurality of terminal accommodating chambers 2 partitioned by a partition plate 1, and a housing 6 in which joint terminals 3 are accommodated in these terminal accommodating chambers 2. In a joint connector in which a plurality of short terminals 4 and 5 each having a contact tongue piece 7 are fitted to connect the joint terminals 3 to each other, the short terminal 3 is properly fitted into the housing 6. Step portions 20 and 2 that prevent the short terminal 3 from fitting except when
1 is provided on the short terminals 4, 5 and the housing 6.

[Effect of idea]

Therefore, according to the joint connector of this invention, if the short terminal 5 is not inserted into the proper terminal accommodating chamber 2 of the housing 6, the insertion of the short terminal 5 will be incomplete, and the connection of the short terminal 5 will be interrupted. Therefore, it is possible to know very easily whether or not a proper circuit is established, and a highly reliable joint connector can be provided.
