Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for connecting a small electronic device, and more particularly to a connector provided with two contact blocks.

[0002]

2. Description of the Related Art Conventionally, such a connector has been required to have a smaller external shape, a larger number of pins and a narrower pitch connection.

FIG. 4 is an exploded perspective view of a conventional connector. As shown in FIG. 4, this connector comprises a male connector 2 and a female connector 1. The male connector 2 has a substantially rectangular parallelepiped housing 10 having an erroneous insertion prevention projection 14 formed at one end, and this housing 10 Are provided with a plurality of male contacts 4 held on opposing side surfaces. On the other hand, the female connector 1 includes a substantially concave housing 9 and a plurality of female contacts 3 embedded and held in the housing 9. Further, an erroneous insertion preventing groove 13 is formed at an end of the housing 9 so that the erroneous insertion preventing protrusion 14 of the male connector 2 can be fitted.

When the female connector 1 and the male connector 2 are fitted together, the erroneous insertion preventing projection 14 on the male connector 2 and the erroneous insertion preventing groove 1 on the female connector 1 are provided.
If 3 does not match, the structure cannot be fitted.

However, when the male connector 2 is inserted obliquely, the female contact 3 may be damaged.

For this reason, as one of measures for improving such erroneous insertion, for example, as disclosed in Japanese Patent Application Laid-Open No. 4-308673, erroneous insertion prevention means having the same height as the female connector is provided on both sides of the female connector. It has been proposed to provide a columnar connector guiding means on both sides of a female connector or a female connector, and to provide a structure in which holes provided on both sides of the male connector penetrate the connector guiding means, thereby preventing oblique insertion. I have.

As another improvement, for example, as disclosed in Japanese Patent Application Laid-Open No. 7-282904, a concave portion is formed inside both ends of a female connector housing or along a terminal portion, while a male connector housing has an error. Some are provided with insertion preventing ribs. In this case, if the concave portion of the female connector housing and the erroneous insertion prevention rib of the male connector housing do not coincide with each other, the connector cannot be fitted, so that oblique insertion and erroneous insertion can be prevented.

[0008]

Since the above-mentioned conventional connector is used for small-sized electronic equipment, there is a problem that the outer shape is restricted and the connector housing cannot be enlarged.

That is, of the above-mentioned improvement measures, in the former example, since the erroneous insertion preventing means and the column-shaped connector guiding means are provided at both outer ends on the long side of the connector housing, the outer shape becomes large. Further, in the latter example, since a concave portion is formed inside the female connector housing and a rib is provided on the male connector housing, elastic deformation at the time of oblique insertion can be prevented. Since the recess is provided, it is necessary to increase the thickness of the female connector housing. As a result, as in the former example, the outer shape must be increased.

Therefore, the conventional connector is good when there is no restriction on the outer shape, but when the outer shape is required to be small and a narrow pitch is required, the connector housing cannot be made large. There is a disadvantage that the contact of the female connector or the male connector is bent.

An object of the present invention is to provide a connector capable of preventing a contact breakage of a female connector caused by an oblique insertion of a male connector while minimizing an external size.

[0012]

According to the connector of the present invention, a plurality of first contacts are arranged on opposite sides of a rectangular parallelepiped housing, and first and second holes having different lengths are formed on a bottom surface. Male connector, and a concave housing for accommodating the male connector, and second contacts are respectively provided at positions of the male connector corresponding to the first contacts, and the inside of the concave housing is provided. And a female connector formed with first and second projections fitted on the first and second holes of the male connector on the bottom surface of the male connector.

The first and second holes of the male connector are oblique insertion preventing grooves formed along the longitudinal center line of the bottom surface of the rectangular parallelepiped housing, and the first and second holes of the female connector are formed. Are formed as oblique insertion prevention pins formed along the longitudinal center line of the bottom surface inside the concave housing.

The first and second holes formed in the rectangular parallelepiped housing of the male connector are interchanged with the first and second projections formed in the recessed housing of the female connector. It can also be formed.

Next, a connector according to the present invention is a male connector in which a plurality of first contacts are arranged on opposite sides of a rectangular parallelepiped housing, and a hole is formed on a bottom surface and at a location which is asymmetrical from the center position. And a recessed housing for accommodating the male connector, and second contacts are respectively provided at positions corresponding to the first contacts of the male connector, and on a bottom surface inside the recessed housing. A female connector formed with a projection that fits into the hole of the male connector.

The hole of the male connector is one oblique insertion preventing groove, and the projection of the female connector is
It is configured as one oblique insertion prevention projection formed at a position corresponding to the two oblique insertion prevention grooves.

The hole formed in the rectangular parallelepiped housing of the male connector and the projection formed in the recessed housing of the female connector may be interchanged.

[0018]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a connector according to an embodiment of the present invention. As shown in FIG. 1, the connector in the present embodiment is a female connector 1
And a male connector 2. The male connector 2 has a plurality of male contacts 4 buried and arranged on opposite external side surfaces of a rectangular parallelepiped male connector housing 10, and a large or small oblique insertion hole having a hole on the bottom surface. The prevention grooves 7, 8 are formed by being dug by integral molding. The female connector 1 has a female connector housing 9 having a concave shape for accommodating the male connector 2.
The female contacts 3 are arranged at positions corresponding to the male contacts 4 of the male connector 2 and along the inner side surfaces, respectively, and fitted into the holes 7 and 8 of the male connector 2 on the inner bottom surface of the concave housing 9. The large and small oblique insertion prevention pins 5 and 6 serving as projections are formed by integral molding.

In particular, the oblique insertion preventing grooves 7 and 8 serving as the first and second holes of the male connector 2 are provided in the rectangular housing 1.
The oblique insertion prevention pins 5 and 6 formed along the longitudinal center line of the bottom surface of the female connector 1 and serving as the first and second protrusions of the female connector 1 are provided in the longitudinal direction of the bottom surface inside the concave housing 9. It is formed along the center line.

In the connector having such a structure, when the rectangular parallelepiped male connector housing 10 is positioned perpendicular to the female connector housing 9 and in a normal posture, the oblique insertion prevention pins 5 and 6 on the female connector 1 side are provided. And the oblique insertion prevention grooves 7 and 8 on the male connector 2 side coincide with each other, so that both blocks can be inserted.

As a modification of the above-described embodiment,
The holes 7, 8 formed in the rectangular parallelepiped housing 10 of the male connector 2 and the projections 5, 6 formed in the recessed housing 9 of the female connector 1 may be interchanged.

FIGS. 2A and 2B are cross-sectional views of the connector shown in FIG. 1 in an obliquely inserted state and a reversely inserted state, respectively. First, as shown in FIG. 2A, when the male connector 2 is to be inserted obliquely into the female connector 1, the male connector housing 10 and the oblique insertion prevention pin 6 of the female connector 1 interfere with each other, and the insertion is not performed. Can not. Therefore, the female contacts 3 provided on the inner side surface of the female connector housing 9 are prevented from bending.

As shown in FIG. 2 (b), when the male connector housing 10 is positioned vertically with respect to the female connector housing 9 and rotated 180 degrees from the normal posture, the female connector 1 Since the oblique insertion prevention pins 5 and 6 having different lengths do not correspond to the oblique insertion prevention grooves 7 and 8 of the male connector 2, insertion of both blocks becomes impossible.

FIG. 3 is an exploded perspective view of a connector showing another embodiment of the present invention. As shown in FIG. 3, a connector according to the present embodiment includes a female connector 1 and a male connector 2.
It is the same as the above-described embodiment in that the female connector housing 9 and the male connector housing 10 each having the contacts 3 and 4 embedded therein are provided. The difference is that one oblique insertion preventing groove 12 is dug in the bottom surface of the male connector housing 10 and at a location that is asymmetrical from the center position to the left and right.
One oblique insertion prevention projection 11 that fits into the oblique insertion prevention groove 12 of the male connector housing 10 is integrally formed on the inner bottom surface.

In the connector having such a structure, when the male connector housing 10 is positioned vertically and in a normal posture with respect to the female connector housing 9, the oblique insertion prevention projection 11 on the female connector side and the oblique insertion on the male connector side are provided. The prevention grooves 12 coincide, and the insertion of both blocks becomes possible.
Therefore, even if the male connector 2 is inserted obliquely into the female connector 1, the male connector housing 10 and the oblique insertion prevention projection 11 of the female connector 1 interfere with each other and cannot be inserted. The plurality of female contacts 3 installed on the side are not bent. Also, when the male connector housing 10 is positioned perpendicular to the female connector housing 9 and rotated 180 degrees from the normal posture, the oblique insertion prevention projection 1
Since 1 does not coincide with the oblique insertion prevention groove 12 of the male connector 2, insertion of both blocks becomes possible.

As a modification of the above-described embodiment,
An oblique insertion prevention groove 12 as a hole formed in the rectangular parallelepiped housing 10 of the male connector 2 and an oblique insertion prevention protrusion 11 as a projection formed in the recessed housing 9 of the female connector 1
Can be realized in the same way even if they are formed by replacing the above.

[0027]

As described above, in the connector of the present invention, the protrusion or groove is provided on the inner bottom surface of the female connector housing, and the groove or protrusion is fitted on the bottom surface of the male connector housing. This allows both blocks to be inserted only when the male connector is positioned in the proper posture with respect to the female connector, thereby preventing erroneous insertion and preventing deformation of the female connector of the female connector due to oblique insertion. This has the effect.

Further, the connector of the present invention employs an oblique insertion prevention mechanism and has a structure capable of holding the female contact in the female connector housing, so that the thickness can be reduced and the external size can be minimized. There is an effect that the present invention can be applied to a small electronic device having a limited outer size.
