[0004]

In the above-mentioned conventional connector device, when the cable is properly pulled in the direction opposite to the direction in which the receptacle 1 is fitted, the cable comes off when the pressure contact force of the contact piece 19 is exceeded. When pulled in a direction perpendicular to the correct direction or in an oblique direction, the receptacle 1
There is a risk that a prying force will act between and the fitting part 5 of the electronic device 3, leading to the destruction of either side. Specifically, in FIG. 3, there is a risk that the twisting force acts between the fitting convex portion 11 and the fitting concave portion 17 and the connection pattern 13, the contact piece 19, the fitting convex portion 11 and the like are destroyed. It was In particular, with the downsizing of electronic devices, it has been a problem that the thickness and size of parts cannot be increased to increase the strength against external forces such as the aforementioned twisting force, which is a problem. Such a problem exists not only in the receptacle but also in the plug. The same problem also exists when other metal parts or columnar terminal parts are used instead of the connection pattern and the contact piece for mechanical and electrical connection.

The present invention solves such a conventional problem, and provides a connector device which is not broken even if the cable is pulled in a direction perpendicular to the correct direction or in an oblique direction. The purpose is to

[0006]

In order to achieve the above object, the present invention provides a flange portion on the outer periphery of a housing of a plug or a receptacle to be fitted with an electronic device, and a flange is provided on a wall surface of a fitting portion of the electronic device. This is a connector device for converting the twisting force due to an external force into a rotational force and pulling it out by making the end of the part a fulcrum.

[0007]

When the cable connected via the plug or receptacle is pulled in the direction perpendicular to the correct direction or in the diagonal direction, the receptacle or plug will have a larger circle than the conventional one with the end of the flange as the fulcrum. Draw and rotate. As a result, the force that has conventionally worked as the prying force is converted into a rotational force, and becomes a force that linearly pulls out the plug or the receptacle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. An opening 7 is formed on the wall surface of the fitting portion 5 of the electronic device 3, and the printed circuit board 9 is exposed inside. The printed circuit board 9 is formed with a fitting convex portion 11 and the fitting convex portion 11 is formed.
The connection pattern 13 is formed on the surface of the. On the other hand, on the receptacle 1 side, a fitting concave portion 17 into which the fitting convex portion 11 is fitted is formed. A contact piece 19 is formed on the inner upper surface of the fitting recess 17 and corresponds to the connection pattern 13. The contact piece 19 has a tip bent and has a function of a leaf spring. The rear end is connected to the wire of the cable 15 by soldering or caulking. Further, a flange portion 25 is provided on the outer periphery of the housing 23 outside the insertion portion 22 of the receptacle 1 which is inserted inside the opening 7 of the electronic device 3 by the fitting. Then, one side dimension b of the width of the flange portion 25 is made sufficiently larger than the length dimension a of the insertion portion 22. Further, the fitting convex portion 11 has a tapered shape and is trapezoidal as a whole. The fitting concave portion 17 has a trapezoidal shape corresponding to the fitting convex portion 11. And b for a
Is the fulcrum (c or d) at the end of the flange 25.
As the receptacle 1 is rotated, the fitting concave portion 17 has a size large enough not to come into contact with the fitting convex portion 11 with a strong force that causes destruction.

Next, the operation of the above embodiment will be described.
FIG. 2 shows a state in which the receptacle 1 is fitted in the fitting portion 5 of the electronic device 3. The trapezoidal fitting protrusion 11 and the fitting recess 17 serve as guides, the fitting is performed at the correct position, and the contact piece 19 corresponding to the connection pattern 13 is correctly electrically and mechanically connected.

Now, in this fitted state, the cable 15 connected to the electronic device 3 through the receptacle 1
Consider a case in which an unexpected external force occurs. That is, when the cable 15 is pulled in a direction perpendicular to the correct direction (right direction in the drawing) (vertical direction in the drawing) or in an oblique direction, a force is applied to the receptacle 1 in the clockwise direction or the counterclockwise direction. Conventionally, this force acts as a twisting force, and there is a risk that the electronic device 3 and the receptacle 1 may be destroyed.
However, according to the present embodiment, the end portion of the flange portion 25 serves as a fulcrum, so that the receptacle 1 attempts to rotate in a large circle having a radius of the dimension b. At the beginning of this rotation, the receptacle 1 is in the correct direction (rightward in the figure).
When the tensile force exceeds the pressure contact force of the contact piece 19, the fitting is disengaged and the receptacle 1 becomes
Removed from. Although this removal is not performed completely in a straight line, since the fitting protrusion 11 and the fitting recess 17 are trapezoidal, it is possible to prevent them from coming into strong contact with each other. 11 or fitting recess 1
It is possible to prevent the destruction of 7 and the like.

In the above embodiment, the receptacle 1
However, a plug may be used in other embodiments. Further, in the above-mentioned embodiments, the description has been made assuming that the fitting convex portion 11 is formed on the electronic device 3 side and the fitting concave portion 17 is formed on the receptacle 1 side, but in other embodiments, these convex portions and concave portions are formed. It does not matter if they are reversed. Further, the electrical connection has been described as being performed by the connection pattern 13 and the contact piece 19, but in other embodiments, it may be performed by another metal component or a cylindrical terminal component.

[0012]

As is apparent from the above-described embodiment, the present invention is such that even if the cable connected by the plug or the receptacle is pulled in the direction perpendicular to the correct direction or in the oblique direction, the plug or the receptacle is provided with the end portion of the flange portion. Since it rotates in a large circle with the fulcrum as the fulcrum and is linearly removed at the beginning of rotation, avoiding the risk of breaking the fitting part of the electronic device or the plug or receptacle without receiving the prying force as in the past. it can. Therefore, in order to prevent destruction, it is possible to expect an effect that the strength of parts does not need to be increased and miniaturization of electronic devices can be promoted.
