Description

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

[Conventional technology]

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 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 contact tongue 7 of the short terminals 4 and 5 connected to the terminal 3 located in the chamber 2 and between the back surface 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.

Therefore, in order to solve this problem, for example, as shown in FIGS. 5 and 6, the rear surfaces 4a, 5a of the respective short terminals 4, 5 connected to the joint terminal 3 set in the housing 6.
A plurality of ribs 14 for preventing backlash are formed on the inner surface of the presser cover 12, and after the joint terminal 3 is set in the housing 6, the presser cover 12 is closed. The rattling prevention rib 14 formed on the inner surface of the short terminal is brought into contact with the back surface 4a, 5a of each short terminal to prevent the short terminal 4, 5 from swinging within the housing 6. A device has been proposed in which the housing does not cause looseness within the housing.

[The problem that the idea aims to solve]

However, since the contact surface of the short terminal rattling prevention rib 14 with the short terminals 4 and 5 of this structure is the apex of a triangle, the apex (apex) of the rib 14 may undergo plastic deformation due to long-term use of the connector. As a result, a gap is created between the tip of the rib 14 and the back surface 4a, 5a of the short terminal, resulting in the problem that backlash occurs again.

[Means to solve the problem]

The present invention has been made to solve the above-mentioned problems of the prior art. The joint connector of the present invention has a plurality of terminal receiving chambers 2 separated by a partition plate 1, and a housing 21 in which joint terminals 3 are received in the terminal receiving chambers 2.
A plurality of short terminals 4, 5 having a plurality of contact pieces 7 are fitted to the joint terminals 3 to connect them to each other, and the rear 4 of these short terminals 4, 5 is
In the plastic joint connector, a pressing lid 22 attached to the housing 21 is abutted against the aforesaid housing 21a, 5a. An anti-rattle rib 26 is provided on the inner surface of the pressing lid 22, and a through hole 25 is formed in the central back surface of the anti-rattle rib 26 to impart elasticity to the anti-rattle rib 26.
When the pressing lid 22 is attached to the terminal 2, the anti-backlash rib 26 elastically presses the short terminals 4, 5 so that the short terminals 4, 5 are connected to the joint terminal 3 without backlash.

〔Example〕

The present invention will be explained in detail below based on the embodiment shown in FIGS. , and the explanation of the same structural parts will be omitted.

21 is a connector housing, and inside this connector housing 21, a plurality of terminal accommodating chambers 2 are formed by a partition wall 1 similar to that shown in the conventional example, and in these terminal accommodating chambers 2, joint terminals 3 are formed. are fitted. Reference numeral 22 denotes a presser cover connected to the edge of the opening of the connector housing 21 via a thin hinge 23, and the inner surface of the presser cover 22 is formed as clearly shown in FIG. That is, a rib 24 is formed at the center of the inner surface of the presser lid 22 to prevent the two rows of short terminals 4 and 5 from coming into contact with each other. In addition, on the inner surface of the presser lid 22, an appropriate number of rattling prevention ribs 26 are provided on both sides of the ribs 24, perpendicular to the ribs 24, and a through hole 25 is bored in the back surface of the central part in the length direction of the rattling prevention ribs 26. The through hole 25 penetrates through the presser cover 22 in the thickness direction. Therefore, a rattling prevention rib 26 which is perpendicular to the rib 24, spans the through hole 25, and is imparted with elasticity is formed integrally with the presser lid 22.

In this way, in this embodiment, the presser cover 22
When this presser cover is attached to the connector housing 21, the connector housing 2
1, the respective short terminals 4 and 5 inserted into
The short terminals 4 and 5 are always elastically pressed by the rattling rib 26 and are prevented from rattling.

[Effect of idea]

Therefore, according to the joint connector of the present invention,
Since the short terminals 4 and 5 housed in the connector housing 21 are always pressed elastically by the anti-backlash rib 26, plastic deformation of the rib 26 is suppressed, and play in the short terminals 4 and 5 is prevented over a long period of time. It has the effect of effectively maintaining the stop.
