Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mechanism of the open/close member of a flat cable connector, which allows a female connector to be inserted into a male connector with a single touch.

First, this type of conventional technology will be described.

1 to 3 are diagrams showing the structure of a conventional connector. FIG. 1 shows only a male connector A, and FIG. 2 shows a state in which a female connector B is fitted into the male connector A.

FIG. 3 shows the state in the middle of inserting the female connector B into the male connector A, and this is when the female connector is about to be inserted while the switch 6 is in the closed state. . At this time, both corners C of the mating surface on the bottom of the female connector B are obstructed by the multi-striped groove 9 provided at the upper end of the switch 6 to prevent fingers from slipping when operating the switch, and the female connector B is closed. This indicates that a malfunction occurs in which the male connector A cannot be mated.

In order to solve the above-mentioned drawbacks, the present invention improves the structure of the connector's opening/closing element, which is pivotally supported so that it can rotate in opposite directions, and becomes engaged with the female connector when rotated in the closing direction. In a male connector opener that has an upper engagement claw that is disengaged when rotated in the opening direction, there are multiple stripes on the upper end of the opener to prevent fingers from slipping during opening and closing operations. In addition to providing a groove, a rib with a smooth surface is disposed in a direction exactly or substantially perpendicular to the multi-striped groove, thereby providing a connector opening/closing element that allows male and female connectors to be fitted with one touch.

Figures 4 to 6 show the structure of an embodiment of the connector switch according to the present invention, and the upper end of the switch 6 is provided to prevent fingers from slipping when operating the switch, as in the conventional case. A multi-striped groove 9 is provided for this purpose. Ribs 10 with smooth surfaces are arranged in a direction exactly or almost perpendicular to the multi-striped grooves 9. This rib 10 is made with a dimension slightly higher than the top of the groove crest of the multi-row groove 9.

In the figure, A indicates a male connector having a male terminal 1, B indicates a female connector having a flat cable 2, and C indicates both corners of the fitting surface. Reference numeral 4 denotes a support shaft around which the open/close member 6 rotates. The opening/closing element 6 has an engaging claw 7 to prevent the female connector from falling off during the closing rotation, a push-up finger 8 for pushing up the female connector and releasing the mating of the male and female connectors during the opening rotation, and an operator's opening/closing operation. It is equipped with multiple grooves 9 to prevent fingers from slipping.

Reference numeral 10 denotes a rib, which is provided in a portion of the multi-striped groove 9 provided at the upper end of the switch 6 in a direction exactly or almost perpendicular to the multi-slotted groove. Reference numeral 16 denotes a frame of the male connector, and the upper part thereof constitutes a side wall 17 that pivotally supports the switch 6.

Now, in such a mechanism, when an attempt is made to insert the female connector B into the male connector A when the switch 6 is in the closed state as shown in FIG. becomes. This is because the ribs 10 are slightly higher than the multi-line grooves 9. If the female connector B is then pushed in further, the open/close member 6 is rotated in the opening direction about the support shaft 4 while both corners C of the female connector B slide on the smooth surface of the rib 10, as shown in FIG. Therefore, the female connector B can move in the direction of mating with the male connector A.

Although the rib 10 is placed at the center of the width of the multi-line groove 9 in this example, it can perform the same function no matter where it is placed within the width of the switch, and it goes without saying that the rib width can also be set arbitrarily. be.

As is clear from the above description, the structure of the present invention allows the female connector B to be mated simply by pushing it in even when the switch 6 is in the closed state. In other words, it provides the extremely remarkable effect of being able to mating with one touch using one hand (without having to use the other hand to open the switch 6).

Claims (1)

[Scope of utility model registration request] A pair of left and right switches are interposed between the side walls arranged in parallel on the front and rear sides of the male connector board section in which male terminals are implanted, and are pivotally supported so as to be rotatable in opposite directions. It is provided with an upper engaging pawl that engages with the female connector when the switch is rotated in the opening direction, and is disengaged when the switch is rotated in the opening direction. In a connector having a structure in which push-up fingers are provided to push up the female connector in a protruding manner, a multi-striped groove and a rib perpendicular or almost perpendicular to the multi-striped groove are provided on the inside of the upper end of the opening/closing member in the closing direction. A connector opening/closing element, characterized in that the ribs are slightly higher than the peaks of the multi-line grooves.
