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. 4. 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 pawl 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 the case of such a conventional joint connector, when fitting the short terminals 4 and 5 into the housing 6, the respective terminal accommodating chambers 2 of the housing 6 and these terminal accommodating chambers are There is play between the short terminals 4 and 5 connected to the terminal 3 located in the chamber 2 and the contact tongue piece 7, and between the back of the fitted short terminals 4 and 5 and the presser cover 12. Therefore, the fitting mode of the respective short terminals 4 and 5 fitted into the housing 6 may be in an inclined state as shown in FIG. There was a problem in which the short terminals 4 and 5 were short-circuited.

[Purpose of invention]

The present invention has been made to solve these conventional problems, and includes steps that can be fitted to each other on the back side edge of the short terminal and the inner surface of the holding cover of the housing. It is an object of the present invention to provide a joint connector in which stable connection of each short terminal at a proper position within a housing can be ensured by the fitting action of both stepped portions.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIGS. 1 to 3. The same parts between the structure in this embodiment and the structure shown in the conventional example are The reference numerals are given and the structural description thereof will be omitted.

A plurality of protrusions 20 each having a triangular cross section are provided on the inner surface of the presser cover 12 provided on the connector housing 6, and the protrusions 20 are integrally formed with the presser cover 12. . The other structure is the same as the connector housing 6 described in the conventional example. 21 and 22 are short terminals according to this embodiment, and these short terminals 21, 2
As in the conventional example, a plurality of contact tongue pieces 7 are integrally formed on the connector housing 6 to be in contact with the joint terminals 3 incorporated in each terminal receiving chamber 2 of the connector housing 6. Also, these short terminals 2
A plurality of triangular notches 23 into which the protrusions 20 having a triangular cross section are fitted are provided on the dorsal edges of the points 1 and 22.
is formed, and a corner 24 on the dorsal side edge is further provided with a corner 24 on which the above-mentioned protrusion 20 comes into contact. Other configurations are the same as those of the conventional example.

The above is the configuration of this embodiment.Next, its operation will be described.
1 and 22 are inserted into the connector housing 6 so as to be in contact with the joint terminals 3, and then the connector housing is assembled with the short terminals 21 and 22 by closing the holding cover 12 of the connector housing. At this time, each protrusion 20 protruding from the presser cover 12 is fitted into the notch 23 provided in the short terminals 21, 22, so that these short terminals 21, 22 are attached to the connector housing. Inside, it is inserted and held in place without any play, and a stable connection can be maintained. Further, since either of the protrusions 20 is located between the short terminals 21 and 22, the short terminals 21 and 22 are connected to each other.
This has the effect of providing a joint connector with high connection reliability and no problems caused by short circuits between the two. In the above embodiment, the protrusion 20 is held down by the lid 12.
and the notch 23 is provided in the short terminal 21, 2.
However, conversely, protrusions having the same effect as the protrusions 20 may be provided on the short terminals 21 and 22, and a notch into which these protrusions are fitted may be provided on the presser cover 12.

[Summary of the idea]

As described above, the present invention has a housing 6 which has a plurality of terminal accommodating chambers 2 partitioned by a partition plate 1 and in which joint terminals 3 are accommodated in these terminal accommodating chambers 2. A plurality of short terminals 21 and 22 having a plurality of contact tongues 7 are fitted to connect the joint terminals 3 to each other, and a presser cover 12 attached to the housing 6 is brought into contact behind these short terminals 21 and 22. In the joint connector constructed as follows, the short terminals 21, 2
2 and the step portion 2 that fits together with the presser lid 12.
2 and 23 so that the short terminals 21 and 22 are connected to the joint terminal 3 in a normal state.

[Effect of idea]

Therefore, according to the joint connector of this invention, by closing the presser cover 12 after inserting the short terminals 21 and 22 into the connector housing 6, each protrusion protruding from the presser cover 12 can be removed. 20 are fitted into the notches 23 provided in the short terminals 21 and 22, so that the short terminals 21 and 22 are fitted and held in place within the connector housing without play, and a stable connection is achieved. Can be maintained. In addition, since one of the protrusions 20 is located between the short terminals 21 and 22 on both sides, a joint connector with high connection reliability can be obtained without problems such as short circuits between the short terminals 21 and 22. There is an effect that can be provided.
