Card connector with a slider braking unit
A disclosed card connector includes a housing main unit including a card insertion slot through which a card is inserted into the housing main unit in a predetermined direction; a slider attached to the housing main unit in such a manner as to be slidable along the predetermined direction, wherein the card inserted into the housing main unit is ejected by moving together with the slider as a spring force moves the slider from a position away from the card insertion slot toward the card insertion slot; and a slider braking unit configured to apply a braking force to the slider in such a manner that the braking force increases as the slider moves toward the card insertion slot.
1. A card connector comprising:
a housing main unit comprising a card insertion slot through which a card is inserted into the housing main unit in a predetermined direction;
a slider attached to the housing main unit in such a manner as to be slidable along the predetermined direction, wherein the card inserted into the housing main unit is ejected by moving together with the slider as a spring force moves the slider from a first position at which the slider is away from the card insertion slot to a second position toward the card insertion slot at which the slider is stopped; and
a slider braking unit configured to apply a braking force to the slider in such a manner that the braking force increases as the slider moves from the first position to the second position.
2. The card connector according to claim 1 , wherein the slider braking unit comprises a brake shoe unit, wherein:
the brake shoe unit is formed integrally with the housing main unit and protrudes above a top surface of the housing main unit;
the brake shoe unit comprises a top face having a triangular shape viewed from the top, wherein an apex of the triangular shape is on a far side and a base of the triangular shape is on a near side with respect to the card insertion slot; and
the top face of the brake shoe unit is tilted in such a manner that the base is higher than the top surface of the housing main unit than is the apex.
3. The card connector according to claim 2 , wherein:
the brake shoe unit comprises a fixed end and a free end, wherein the fixed end is near the back of the card connector and is connected to the housing main unit and the free end is near the card insertion slot and is not connected to the housing main unit, thereby forming a cantilever structure.
4. The card connector according to claim 1 , further comprising:
a card braking unit configured to apply a braking force to the card while the card is being ejected.
5. The card connector according to claim 4 , wherein:
the card braking unit is formed on the housing main unit and protrudes above a top surface of the housing main unit; and
the card braking unit comprises one or more push-up springs configured to push up a bottom face of the card inserted into the housing main unit.
6. The card connector according to claim 5 , wherein:
a pair of the push-up springs is provided in such a manner as to support a left side and a right side of the bottom face of the card near a rear edge of the card.
7. The card connector according to claim 5 , wherein:
the push-up springs are arranged in such a manner that the card braking unit has an upside down W shape fixed at both ends to the housing main unit with two protruding parts in contact with the bottom face of the card.
8. An apparatus comprising:
a housing having a slot through which a card is inserted in a first direction;
a slider attached to the housing and slidable in the first direction, wherein the card is ejected by moving together with the slider from a first position at which the slider is away from the slot to a second position toward the slot at which the slider is stopped; and
means for applying a braking force to the slider such that the braking force increases as the slider moves from the first position to the second position.
