JPS6011569Y2 - Flat cable connector - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector used for electrically connecting flat cables such as flat cables or ribbon cables, and particularly to a structure for preventing cables from being pulled out.

Conventionally, various structures have been proposed for this type of connector in order to prevent the cable from coming off.

However, those structures generally have the problem of being cumbersome to operate.

In addition, we make two types of connectors, one with a structure that prevents the cable from being removed and one that does not, but this is uneconomical, and the structure that prevents the cable from being removed later becomes desirable or unnecessary. However, it is inconvenient because it cannot meet that request.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a flat cable connector with a cable removal prevention structure that is extremely easy to operate.

A further object of the present invention is to make the cable removal stopper structure detachable, thereby making it possible to obtain a compact flat cable connector as needed.

Examples will be described below with reference to the drawings.

Referring first to FIGS. 1 and 2, an embodiment of the flat cable connector according to the present invention shown therein is an insulating connector incorporating a plurality of conductive contacts 1 in a row spaced apart from each other. It includes a housing 2 and a locking part 3 assembled on the outside of the housing 2.

The housing 2 incorporating the contact 1 is mounted on a printed board 4 or the like as shown in FIG. The receiver can be inserted into hole 7.

As shown in FIG. 3, the cable 5 inserted into the cable insertion hole 7 has its conductor portion 6 in contact with the contact 1, thereby establishing electrical connection with the connector.

Returning to FIG. 1, projections 8 are provided on both end surfaces of the housing 2 in the arrangement direction of the contacts 1, respectively.

On the other hand, the lock component 3 is provided with a fulcrum 9 in the center, and has spring pieces 10 on the left and right sides of the fulcrum 9, which utilize the elasticity of the material.

Furthermore, opposing arms 11 are provided at the tips of the spring pieces 10.

Further, a window 12 is formed in the arm 11.

An arm 11 is attached to the lock component 3 so as to face the end surface of the housing 2 in the arrangement direction of the contacts 1.

At this time, the protrusion 8 fits into the window 12 of the arm 11, thereby preventing the lock part 3 from coming off.

The lock component 3 assembled in the housing 2 in this manner has its center fulcrum 9 in contact with the side surface of the housing 2, and the arm 1 is pulled up by the spring force of the spring piece 10 to bring its surface 13 into contact with the protrusion 8. in a state.

When the tip of the spring piece 10 is pressed against the housing 2, the spring piece 10 is bent and the arm 11 is lowered.

That is, the arm 11 can move up and down.

The arm 11 has a finger piece 14 projecting forward of the cable insertion hole 7 at its tip.

On the other hand, notches 15 are provided at both edges near the tip of the cable 5.

To connect the cable 5 to this flat cable connector, insert the cable 5 into the cable insertion hole 7 of the housing 2 while pushing down the tip of the spring piece 10 of the lock component 3, as shown in FIG. do.

After that, when the pressing force on the spring piece 10 is released, the restoring force of the spring piece 10 causes the arm 1 to move as shown in FIG.
1 is raised, and the waist finger piece 14 enters the notch 15 of the cable 5.

In this way, the cable is not only electrically connected to the connector, but also mechanically locked to prevent it from coming off.

Furthermore, by pulling the cable 5 while pushing down the tip of the spring piece 10, the cable 5 can be easily pulled out from the connector.

Note that the lock component 3 may have three fulcrums 9 as shown in FIG. 5.

Further, the above-mentioned connector can function as a normal flat cable connector even when the lock component 3 is not assembled.

As explained above using the embodiments, according to the present invention,
A flat cable connector with a cable removal prevention structure that is extremely easy to operate is obtained.

This connector can also be used as a small flat cable connector by removing the cable removal prevention structure.
