Abstract
Description
- This application claims priority to prior Japanese application JP 2005-41003, the disclosure of which is incorporated herein by reference.
- This invention relates to a connector connectable selectively to two types of cards different in width.
- For example, a card called an express card is used as an object to be connected to the connector. The express card is produced in accordance with a card standard defined by PCMCIA (Personal Computer Memory Card International Association) and has two types including a narrow card/34 module and a wide card/54 module. Therefore, a connector used for connection of the express card is desired to be connectable to both of the two types of cards.
- For example, a connector of the type is disclosed in Japanese Unexamined Patent Application Publication (JP-A) No. 2004-318511 and has a housing adapted to receive a card to be inserted therein. The housing has a left insertion space and a right insertion space. Between the left and the right insertion spaces, a particular mechanism is disposed for guiding the narrow card to the left insertion space or the right insertion space. The mechanism has a rotary member rotated when it is pushed by the card. Thus, the narrow card is guided by the mechanism to one of the left and the right insertion spaces to be inserted therein. On the other hand, the wide card is inserted into a wide space as a combination of the left and the right insertion spaces.
- As described above, the above-mentioned connector is adapted to connect each of two types of cards different in width. However, since the narrow card is guided by the particular mechanism having the rotary member to the left or the right insertion space, the card may not smoothly be guided to a predetermined connecting portion.
- It is therefore an object of this invention to provide a connector in which not only a wide card but also a narrow card is smoothly guided to a predetermined connecting position.
- It is another object of this invention to provide a connector reduced in size.
- It is still another object of this invention to provide a connector in which a card is smoothly ejected.
- It is yet another object of this invention to provide a connector which is capable of saving a space.
- Other objects of the present invention will become clear as the description proceeds.
- According to an aspect of the present invention, there is provided a connector adapted to be selectively connected to two types of cards inserted towards an insertion direction and different from each other in width thereof, the connector comprising a housing defining a guide space and having a guide portion for guiding an insertion of a selected one of the cards, the guide portion extending in the guide space in a particular direction intersecting the insertion direction, and an eject mechanism for moving the selected one towards a removing direction opposite to the first direction, the eject mechanism comprising an eject member to be engaged with the selected one and moved together with the selected one, an operating member for moving the eject member towards the removing direction, and a rotary member having a rotation center and rotatable around the rotation center to transmit operation of the operating member to the eject member, the rotation center being disposed in the guide space.

Theinclined guide surface 2b 1 is inclined with respect to the first direction A1. - When the insertion of the
first card 11 further proceeds, thefirst card 11 is moved in the first direction A1 and a particular direction or a second direction A2 perpendicular to the first direction A1. Then, a third stage illustrated inFIG. 7 is reached. In the third stage, thecorner portions 11 d of thefirst card 11 are started to be guided by aparallel guide surface 2b 2 of theguide space 2 b of thehousing 2. Theparallel guide surface 2b 2 is parallel to the firs direction A1. - When the insertion of the
first card 11 still further proceeds, thefirst card 11 is moved only in the first direction A1. Then, a fourth stage illustrated inFIG. 8 is reached. In the fourth stage, the taperedportion 11 e of thefirst card 11 is started to be guided by aninclined guide surface 2b 3 of theguide space 2 b of thehousing 2. Theinclined guide surface 2b 3 is also inclined with respect to the first direction. - When the insertion of the
first card 11 yet further proceeds, thefirst card 11 is moved in the first and the second directions A1 and A2. Then, a fifth stage illustrated inFIG. 9 is reached. In the fifth stage, the taperedportion 11 e of thefirst card 11 is started to be guided by aparallel guide surface 2b 4 of theguide space 2 b of thehousing 2. - When the insertion of the
card 11 further proceeds, thefirst card 11 is moved only in the first direction A1. Then, a sixth stage illustrated inFIG. 10 is reached. In the sixth stage, a left side surface of the groove 11c 1 on the left side of the bottom surface of thefirst card 11 is guided by theparallel guide surface 2b 4 of theguide space 2 b of thehousing 2. InFIG. 11 , an area between twobroken lines path 2b 5 of thefirst card 11 in theconnector 1. A combination of the inclined guide surfaces 2 b 1 and 2 b 3 will be called an inclined surface. A combination of the inclined guide surfaces 2 b 1 and 2 b 3 and theparallel guide surfaces 2 b 2 and 2 b 4 will be referred to as a guide surface. - Referring to FIGS. 12 to 17, the
connector 1 will be described in detail. - The
housing 2 has aninsertion slot 2 h through which the card is inserted into thehousing 2. Therotary lever 5 has ahole 5 a fitted over theshaft 2 g of thehousing 2. Therotary lever 5 has oneend 5 b engaged with a right-angled portion 3 b formed at an end of thefirst eject bar 3. Therotary lever 5 has theother end 5 c provided with ahole 5c 1 engaged with a protrudingportion 4 d formed in the vicinity of a curvedrear end 4 c of thesecond eject bar 4. Therear end 4 c of a smooth shape is positioned nearer to theinsertion slot 2 h than engagingportions second eject bar 4 and therotary lever 5. Theshaft 2 g of thehousing 2 is disposed in theguide space 2 b. Since therear end 4 c (seeFIG. 14 ) of thesecond eject bar 4 has an R shape (smooth shape), therear end 4 c is brought into contact with an end of the card to smoothly guide the card to a predetermined fitting position. Therear end 4 c will be referred to as a contact portion. - The
second eject bar 4 further has an extendedportion 4 e extended from therear end 4 c. Theextended portion 4 e has anend 4 f displaced from therear end 4 c towards the insertion direction or the first direction A1. - Referring to FIGS. 18 to 25 in addition, description will be made of the insertion process of the
first card 11 more in detail. - In a first stage illustrated in
FIG. 18 , thefirst card 11 is started to be inserted into thehousing 2. In the first stage, thesecond eject bar 4 is faced to thefirst card 11. - When the insertion of the
first card 11 slightly proceeds to reach a second stage illustrated inFIG. 19 , thefirst card 11 is closely adjacent to thesecond eject bar 4. Further, thecorner portions 11 d of thefirst card 11 are brought into contact with the inclined guide surface 1b 1 to be guided. - When the insertion of the
first card 11 further proceeds, a third stage illustrated inFIG. 20 is reached. In the third stage, thefront end 11 a of thefirst card 11 is brought into contact with the curvedrear end 4 c of thesecond eject bar 4. - When the insertion of the
first card 11 further proceeds, a fourth stage illustrated inFIG. 21 is reached. In the fourth stage, thefront end 11 a of thefirst card 11 pushed therear end 4 c of thesecond eject bar 4 to slide thesecond eject bar 4. At this time, theparallel surface 11 f of thefirst card 11 is guided by theparallel guide surface 2b 2 of theguide space 2 b. - When the insertion of the
first card 11 further proceeds, a fifth stage illustrated inFIG. 22 is reached. In the fifth stage, thefront end 11 a of thefirst card 11 further pushes therear end 4 c of thesecond eject bar 4 to further slide thesecond eject bar 4. In addition, the taperedportion 11 e of thefirst card 11 slides along theinclined guide surface 2b 3 of theguide space 2 b of thehousing 2. - When the insertion of the
first card 11 further proceeds, a sixth stage illustrated inFIG. 23 is reached. In the sixth stage, thesecond eject bar 4 slides to a final position of its stroke. The taperedportion 11 e further slides along theinclined guide surface 2b 3. - When the insertion of the
first card 11 further proceeds, a seventh stage illustrated inFIG. 24 is reached. In the seventh stage, the taperedportion 11 e at a left corner of the groove 11c 1 on the left side of the bottom surface of thefirst card 11 is started to be guided by theparallel guide surface 2b 4 of theguide space 2 b of thehousing 2. - When the insertion of the
first card 11 further proceeds, an eighth stage illustrated inFIG. 25 is reached. In the eighth stage, the left side surface of the groove 11c 1 on the left side of the bottom surface of thefirst card 11 is guided by theparallel guide surface 2b 4 of theguide space 2 b of thehousing 2. - In case where the
first card 11 is inserted into a left half of thehousing 2 from the outset, thefront end 11 a of thefirst card 11 pushes theeject portion 4 b of thesecond eject bar 4 without contacting theinclined guide surface 2b 1 of thehousing 2. Therefore, thesecond eject bar 4 slides in the first direction A1 inFIG. 1A . Therotary lever 5 is rotated clockwise around theshaft 2 g. Thefirst eject bar 3 slides in the opposite direction A1′ opposite to the first direction A1. - While the present invention has thus far been described in connection with the preferred embodiment thereof, it will readily be possible for those skilled in the art to put this invention into practice in various other manners. For example, although the description is made about a case where express cards are selectively used one at a time, the other cards can be used in place of the express cards.
