Abstract
Description
- 1. Field of the Invention
- The present invention generally relates to a card connector for receiving a card therein, and more particularly to a card connector capable of preventing the card from being ejected out in use.
- 2. The Related Art
- Traditionally, a card connector adapted for being soldered on a circuit board and receiving a card therein has an ejecting device used for withdrawing the card from the card connector. The ejecting device includes a sliding body, a spring and a connecting bar. While the card is inserted into the card connector, the card pushes the sliding body to move. Then the spring is compressed and the connecting bar jostles the sliding body to keep the sliding body and the spring relatively immovable. While the card will be withdrawn from the card connector, the card is again pushed inward to make the sliding body discharged from the connecting bar. And the power stored in the spring is released so as to drive the spring to reposition and further drive the sliding body to reposition. So the sliding body pushes the card to exit from the card connector.
- However, in use, if the card is accidentally pushed inward by an external force, the card connector easily springs the card out through the released power from the spring. As a result, the communication of the card and the circuit board is undeservedly interrupted and the data which is being transmitted is easily lost. So, a card connector capable of preventing the card from being ejected out in use is required.
- An object of the present invention is to provide a card connector adapted for receiving an external card. The card connector includes an insulating housing defining a receiving chamber for receiving the card therein and a sliding recess adjacent to one side of the receiving chamber, a plurality of terminals disposed in the insulating housing and projecting upward into the receiving chamber for electrically connecting the card, an ejecting device and a cover coupled on the insulating housing.
- A top of a side wall of the insulating housing beside the sliding recess defines a gap. The ejecting device includes a sliding body which is slidably disposed in the sliding recess of the insulating housing, a spring restrained between a rear sidewall of the sliding recess and the sliding body, and an ejecting pin. A top face of the sliding body defines a sliding fillister penetrating through an outside of the sliding body to communicate with the gap of the insulating housing. A bottom sidewall of the sliding fillister protrudes upward to form a blocking block spaced from a front sidewall of the sliding fillister and designating a front face thereof as a blocking face. The cover has a top plate of which one side is die-cut to form an elastic slice inclined downward into the sliding fillister and elastically against a top of the blocking block, and a side plate which is against an outside of the side wall. A portion of the side plate is opened to form an opening corresponding to and communicated with the gap of the insulating housing. A rear side edge of the elastic slice further extends outward to form a pushing portion passing through the gap and the opening to stretch outside. A front end of the pushing portion extends forward and is inclined upward to form a guiding eave.
- In the process of the card being inserted into the receiving chamber of the card connector and pushing the sliding body to move rearward, the elastic slice of the cover is elastically propped upward by the blocking block and slides forward with respect to the blocking block. When the card is inserted in place, the elastic slice slips off from the blocking block to resist against the blocking face. When the card needs to be withdrawn from the card connector, the ejecting pin is pushed rearward to reach under the pushing portion by virtue of the guide of the guiding eave, then the ejecting pin keeps being pushed rearward to gradually eject the pushing portion upward and further bring the elastic slice away from the blocking face of the blocking block so as to set free the blocking block and the spring to push the card out
- As described above, the elastic slice of the cover can resist against the blocking face of the sliding body in use, and set free the blocking block when ejecting the card out. So, in use, the sliding body keeps being locked by the elastic slice so that ensures a steady connection between the card and the terminals.
- The present invention will be apparent to those skilled in the art by reading the following description, with reference to the attached drawings, in which:
-
FIG. 1 is a perspective view of a card connector according to an embodiment of the present invention; -
FIG. 2 is a fully exploded view of the card connector ofFIG. 1 ; -
FIG. 3 is a partially exploded view of the card connector ofFIG. 1 ; -
FIG. 4 is a lateral view showing the card connector ofFIG. 1 is in use; -
FIG. 5 is a lateral view showing the card connector ofFIG. 1 is not in use; and -
FIG. 6 is a lateral view showing an external card is being inserted into the card connector ofFIG. 1 . - Referring to
FIGS. 1-6 , acard connector 100 according to an embodiment of the present invention is adapted for receiving an external card (not shown). Thecard connector 100 includes aninsulating housing 10, a plurality ofterminals 20, anejecting device 40 and acover 30. - The insulating
housing 10 defines areceiving chamber 11 for receiving the card therein, and asliding recess 12 adjacent to one side of thereceiving chamber 11. A top of aside wall 14 of theinsulating housing 10 beside thesliding recess 12 defines agap 141. Theterminals 20 are disposed in the insulatinghousing 10 and project upward into thereceiving chamber 11 for electrically connecting the card. Theejecting device 40 includes a slidingbody 41 slidably disposed in thesliding recess 12 of theinsulating housing 10, aspring 42 restrained between a rear sidewall of thesliding recess 12 and the slidingbody 41, and an ejectingpin 43. A pushingarm 411 is formed at a rear end of thesliding body 41 and protrudes sideward into thereceiving chamber 11. A top face of the slidingbody 41 defines asliding fillister 412. A bottom sidewall of thesliding fillister 412 protrudes upward to form ablocking block 413 spaced from a front sidewall of thesliding fillister 412 and designating a front face thereof as a blockingface 414. Thecover 30 is coupled on theinsulating housing 10. Thecover 30 has atop plate 31 of which one side is die-cut to form anelastic slice 311 inclined downward into thesliding fillister 412 and elastically against a top of theblocking block 413, and aside plate 32 which is against an outside of theside wall 14 of theinsulating housing 10. A portion of theside plate 32 is opened to form anopening 321 corresponding to and communicated with thegap 141 of theinsulating housing 10. A rear side edge of theelastic slice 311 further extends outward to form a pushingportion 314 passing through thegap 141 and theopening 321 to stretch outside. A front end of the pushingportion 314 extends forward and is inclined upward to form a guidingeave 315. - In the process of the card being inserted into the
receiving chamber 11 of thecard connector 100 and pushing thesliding body 41 to move rearward via resisting against the pushingarm 411, theelastic slice 311 of thecover 30 is elastically propped upward by theblocking block 413 and slides forward with respect to theblocking block 413. When the card is inserted into thecard connector 100, theelastic slice 311 slips off from theblocking block 413 and resists against the blockingface 414. When the card needs to be withdrawn from thecard connector 100, the ejectingpin 43 is pushed rearward to reach under the pushingportion 314 by virtue of the guide of theguiding eave 315. Then the ejectingpin 43 keeps being pushed rearward to gradually eject the pushingportion 314 upward and further bring theelastic slice 311 away from the blockingface 414 of theblocking block 413 so as to set free theblocking block 413 and thespring 42 to push the card out. - Referring to
FIGS. 1-6 again, a front of theside plate 32 of thecover 30 is punched outward to form anarched restraining tube 36 located in front of the guidingeave 315. A guidingpassage 361 is surrounded by therestraining tube 36 and penetrates through therestraining tube 36 along a front-to-rear direction for guiding and restraining the movement of the ejectingpin 43. A front end of theside wall 14 of theinsulating housing 10 protrudes sideward to form arestraining portion 19 with a guidingfillister 191 being opened in a top thereof. One end of a front edge of thetop plate 31 of thecover 30 extends forward and outward to form an inverted-L shapedrestraining slice 35 covered against therestraining portion 19 and defining arestraining hole 351 which is aligned with the guidingfillister 191 of therestraining portion 19 and the guidingpassage 361 of therestraining tube 36 along the front-to-rear direction. The ejectingpin 43 passes through therestraining hole 351, the guidingfillister 191 and the guidingpassage 361 to eject the pushingportion 314 and theelastic slice 311 upward. A rear edge of the opening 321 of theside plate 32 of thecover 30 extends outward to form a blockingear 37 located behind the pushingportion 314 for blocking an excessive insertion of the ejectingpin 43. - Referring to
FIGS. 2-6 , theelastic slice 311 of thecover 30 extends rearward and is inclined downward in the process of extending rearward. A free end of theelastic slice 311 protrudes downward to form a slidingblock 312. The top of the blockingblock 413 is designed as a slope 413 a substantially parallel to theelastic slice 311. In the process of inserting the card into the receivingchamber 11, the slidingblock 312 relatively slides forward along the slope 413 a of the blockingblock 413 and theelastic slice 311 is gradually propped upward by the slope 413 a. Atransition surface 415 is levelly connected between a front end of the slope 413 a and a top end of the blockingface 414 of the blockingblock 413 for buffering theelastic slice 311 before it slips off from the blockingblock 413. - Referring to
FIG. 2 ,FIG. 4 andFIG. 5 , rear ends of theelastic slice 311 and the slidingblock 312 are connected by a resistingportion 313 which has a cambered cross section for guiding theelastic slice 311 to slip down and up through the joining of the slope 413 a and the blockingface 414 of the blockingblock 413. The resistingportion 313 resists against the blockingface 414 of the blockingblock 413 after the card is inserted in place in the card connector 100 (shown inFIG. 4 ). In this embodiment, the cross section of the resistingportion 313 is substantially of semi-circular shape. A rear end of the slope 413 a of the blockingblock 413 is connected to the bottom sidewall of the slidingfillister 412 and spaced from a rear sidewall of the slidingfillister 412. The resistingportion 313 and the slidingblock 312 are against the bottom sidewall of the slidingfillister 412 between the blockingblock 413 and the rear sidewall of the slidingfillister 412 when there is no card in the card connector 100 (shown inFIG. 5 ), and are against the bottom sidewall of the slidingfillister 412 in front of the blockingblock 413 when the card is inserted in place in the card connector 100 (shown inFIG. 4 ). - Referring to
FIG. 1 andFIG. 2 , thetop plate 31 of thecover 30 defines a blockingplate 316 located over the free end of theelastic slice 311 for preventing theelastic slice 311 from being excessively pushed upward by the ejectingpin 43. In this embodiment, the blockingplate 316 is formed by being die-cut off from one side of thetop plate 31 of thecover 30 behind theelastic slice 311 and then being bent forward against a top of thetop plate 31 to stretch over the free end of theelastic slice 311. - As described above, the
elastic slice 311 of thecover 30 can resist against the blockingface 414 of the slidingbody 41 in use, and set free the blockingblock 413 when ejecting the card out. So, in use, the slidingbody 41 keeps being locked by theelastic slice 311 so that ensures a steady connection between the card and theterminals 20.
