ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a card connector, and more specifically relates to a card connector which holds a card by means of recessed and protruding surfaces located in a card-receiving slot that accommodates the card.
BACKGROUND OF THE INVENTION
Various types of card connectors are known. For example, the card connector
100
shown in
FIG. 6
is disclosed in Japanese Patent No. 2,615,161 issued on May 28, 1997. In card connector
100
, a card-receiving slot
110
, which accommodates a card C′, is located between a frame member
102
and a cover member
104
. Electrical contacts
106
and biasing members
108
, which possess resiliency, are disposed inside the card-receiving slot
110
. When the card C′ is inserted into the card-receiving slot
110
, the card C′ and contacts
106
are electrically connected, and the card C′ is biased toward the cover member
104
by end portions
112
of the biasing members
108
.
Since the biasing members
108
of the card connector
100
are cantilever members in the form of resilient arms, which are formed from a resin material, the resiliency of the biasing members
108
drops with an increase in temperature so that the initial biasing force can no longer be obtained, thus resulting in poor durability.
Since the housing is constructed from two parts, i.e., the cover member
104
and frame member
102
, the number of parts required is increased. Since the biasing members
108
are exposed, they may easily be deformed or broken as a result of colliding with other members during the handling of the cover member
104
.
SUMMARY OF THE INVENTION
The present invention was devised in light of the above points. An important feature of the present invention is to provide a card connector having a card-holding structure that is superior in terms of durability.
Another feature of the present invention is to provide a card connector which has a card-holding structure in which there is no danger of deformation or damage, and in which looseness of the card in the card-receiving slot is prevented.
Still another feature of the present invention is to provide a card connector with a card-holding structure which is easy to manufacture, which has a simple structure and which is inexpensive.
Yet another feature of the present invention is to provide a card connector with a housing which has an integral structure.
The card connector of the present invention has a housing provided with a card-receiving slot that accommodates a card, and electrical contacts that are mounted in the housing and are exposed inside the card-receiving slot, at least one protruding surface is located in one of the two opposite inside surfaces of the card-receiving slot that are substantially parallel to the direction of insertion of the card, while recessed surfaces are located in corresponding positions in the other of the two opposite inside surfaces, and the card is held in the card-receiving slot by the protruding and recessed surfaces.
It is desirable that the card-holding structure comprising recessed and protruding surfaces be integral parts inside the housing thereby providing an integral structure.
It is desirable that card-holding structures be formed at both ends of the housing.
