ABSTRACT:
TECHNICAL FIELD
The present invention relates to a box-shaped connector and, more particularly, to a box-shaped connector having a shape effective for preventing cracks or breakages.
BACKGROUND OF THE INVENTION
Not only in electronic devices such as TV sets or personal computers but also in automobiles or industrial devices, there have been used a number electronic parts, major ones of which can be exemplified by connectors and sockets. Most of these connectors used are generally box-shaped to have a length of several centimeters and a section of about 1 cm×1 cm. As shown in
FIG. 1
, the connector and the socket are conducted by inserting the socket into the connector so that they function as the electronic part. Usually, the connector and the socket thus function as the integral part and are therefore demanded to be accurately connected. As means for this desire, the connector is provided with an erroneous insertion preventing slot, whereas the socket is provided with a bump (or a raised portion) to be snugly fitted in that erroneous insertion preventing slot (as shown in FIG.
1
).
Thus, the bump of the socket is fitted in the erroneous insertion preventing slot of the connector. When the socket is to be inserted, there has frequently arisen a problem that a stress concentrates in the vicinity of the erroneous insertion preventing slot of the connector so that the erroneous insertion preventing slot is cracked or broken (as shown in FIG.
2
and FIG.
3
).
The present invention has been conceived from the aforementioned point of view and has an object to provide a connector which is so shaped as to properly disperse a stress generated when a socket is inserted, thereby to prevent cracks or breakages effectively.
DISCLOSURE OF THE INVENTION
We have made keen investigations and have found that the above-specified problem could be solved by making an insulating wall of such box-shaped connector into a specific shape. The present invention has been completed on the basis of such founding.
According to one aspect of the present invention,
A box-shaped connector includes upper and lower side walls and an insulating wall jointing the upper and lower side walls such that the box-shaped connector is formed to have a section generally of letter “C” by the side walls and the insulating wall, wherein a recess is formed over the face of the insulating wall on a socket insertion side and in the vicinity of a corner made between the side wall and the insulating wall, and wherein the smallest thickness (Tn) of the insulating wall is smaller than the thickness (Tr) of the side walls at portions where the face of the insulating wall on the socket inserting side intersects the side walls.
A box-shaped connector according to another aspect of the present invention, wherein a recess is formed over the face of the insulating wall on the side other than the socket inserting side and in the vicinity of a corner made between the side wall and the insulating wall.
A box-shaped connector according to yet another aspect of the present invention, wherein the recess of claim
1
has a groove depth of 0.5 to 1.0 mm.
A box-shaped connector according to yet another aspect of the present invention, wherein the groove of the recess of claim
1
or
2
has an inside corner formed of a curve having a curvature (R).
A box-shaped connector according to yet another aspect of the present invention, wherein the Tr and Tn has a relation of Tn (mm)=Tr (mm)−(0.05 to 0.15) mm.
A box-shaped connector according to yet another aspect of the present invention, wherein the material is styrene polymers mainly having a syndiotactic structure or resin composites containing the styrene polymers mainly having the syndiotactic structure.
