Memory card connector
View Patent ↗A compact memory card connector with an extended communication distance is provided. This connector has a loading port at its one end, through which a memory card can be accommodated therein. The connector is equipped with a base made of an electrical insulating material, a plurality of contacts arranged on the base so as to electrically contact connecting terminals of the memory card inserted in the connector, and an antenna block, which houses a secondary antenna and is slidable in a direction of inserting the memory card into the connector.
1. A memory card connector having a loading port at its one end, through which a memory card with a primary antenna can be accommodated therein, wherein the memory card connector comprises:
a base made of an electrical insulating material;
a plurality of contacts arranged on said base so as to electrically contact connecting terminals of said memory card inserted in the memory card connector;
an antenna block, which houses a secondary antenna and is slidable in a direction of inserting said memory card into the memory card connector; and
a slide member connected to said antenna block and supported to be slidable relative to said base,
wherein said slide member slides together with said antenna block in synchronization with the insertion of said memory card through said loading port.
2. The memory card connector as set forth in claim 1 , wherein said slide member is configured in a substantially C shape with a pair of arms, and said antenna block is connected to said slide member through projections formed on said arms.
3. The memory card connector as set forth in claim 1 , further comprising a biasing means configured to bias said slide member in a direction of pulling out said memory card from the memory card connector.
4. The memory card connector as set forth in claim 1 , wherein said secondary antenna is housed in said antenna block to be in a face-to-face relation with said primary antenna in a state of accommodating said memory card in the memory card connector.
5. The memory card connector as set forth in claim 1 , further comprising a locking means configured to provide a locking state of inhibiting a movement of said slide member in a direction of pulling out said memory card from the memory card connector when the slide member moves in the insertion direction of said memory card and reaches a required position in the memory card connector, and wherein the locking state is released by further moving said slide member in the insertion direction of said memory card.
6. The memory card connector as set forth in claim 5 , wherein said second antenna is formed to face said primary antenna of said memory card in the locking state of said slide member, and encompass a projection range of said primary antenna of said memory card in the facing direction.
7. The memory card connector as set forth in claim 1 , wherein said antenna block comprises an electronic part for regulating a resonance frequency of said secondary antenna.
8. A memory card connector having a loading port at its one end, through which a memory card with a primary antenna can be accommodated therein, wherein the memory card connector comprises:
a base made of an electrical insulating material;
a plurality of contacts arranged on said base so as to electrically contact connecting terminals of said memory card inserted in the memory card connector; and
an antenna block, which houses a secondary antenna and is slidable in a direction of inserting said memory card into the memory card connector;
a support member configured to support said antenna block to be slidable in the insertion direction of said memory card;
a biasing means configured to bias said antenna block in a direction of pulling out said memory card from the memory card connector; and
a stopper formed at the vicinity of said loading port to limit a movement of said antenna block in the pull-out direction of said memory card.
