1. Field of the Invention
The present invention is generally related to a card connector, and especially to a card connector adapted a card.
2. Description of Related Art
Card connectors are widely used in variety electrical equipments for building electrical paths between the electrical equipments and electrical cards, which are used as storage devices. Usually, card connectors are provided with ejectors to eject electrical cards received in the card connectors, and some have locking members assembled on the ejectors to prevent the electrical cards from pulling out by mistake during working.
A card connector comprises an insulating housing with a plurality of contacts and an ejector receive in the insulating housing for ejecting a card. The ejector has a locking arm retained to a slider for locking with the card. The insulating housing defines a gap on a sidewall besides the ejector thereof, a free end of the locking arm faces to the gap when the slider is at an initial position and staggers with the gap when the slider is at a final position after the card inserted into the insulating housing. That means the locking arm is movable outwardly and away from the card by the free end entering the gap at the initial position and is kept locking with the card at the final position, where the sidewall of the insulating housing limits the free end of the locking arm. However, the intensity of the sidewall is reduced by the gap, so the sidewall is destroyed easily when the card is pulled at the final position by mistake.
Hence, an improved card connector is highly desired to overcome the aforementioned disadvantages of the prior art.
Accordingly, an object of the present invention is to provide a card connector which can prevent the card from being pulled out by mistake in a normal working station.
To achieve the above object, a card connector adapted for a card comprises an insulating housing defining a card receiving space with a card insertion and ejecting direction, a plurality of contacts retained in the insulating housing, and an ejector received in the insulating housing for ejecting the card. The ejector comprises a slider formed with a heart-shaped slot and movable along the card insertion and ejecting direction, a resilient member, a pin member and a latching member retained to the slider and having a locking portion. During an insertion process of the card, the latching member moves upwardly together with the slider, and brings the locking portion to move upwardly to lock the card.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention with attached drawings.
Reference will now be made in detail to the preferred embodiment of the present invention.

The bottom wall 13 has a rib 110 adjacent to the sidewall 11 and a through hole 100 in front of the rib 110, both the rib 110 and the hole 100 extend along the card insertion and ejection direction. A slot 101 defined between the rib 110 and the sidewall 11 is used for guiding the ejector 3, an inner side surface of rib 110 can guide the card 5. The rib 110 is formed with a step on a top surface thereof by an inline surface 112 linking a high rear portion 111′ and a low front portion 111 (referring to

The latching member 33 is a metal slice and has a body 331, a locking portion 330 on a free end of the body 331 and a pair of tabs 332 on the other end of the body 331. The tabs 332 insert into gaps 304 defined on the ejecting portion 303 the slider 30 to retain the latching member 33 to the slider 30 in a bottom-to-top direction. The locking portion 330 is exposed outside the slider 30 after assembled to the slider 30 for locking the card 5.
The ejector 3 is received in to the insulating housing 1, the slider 30 together with the latching member 33 is movably received in the slot 101 of the insulating housing 1; one end of the spring 34 is disposed around a column 140 formed on the rear wall 14 and the other end is set in the receiving hole 302 of the slider 30; one end of the pin member 32 is moveably disposed in the heart-shaped slot 301 of the slider 30 and the other end is securely locked in a hole 103 formed on the blocking wall 113 (referring to

The card 5 defines a cutout 51 on a lateral side corresponding to the locking portion 330 of the latching member 33 when the card 5 inserts into the card connector. The locking portion 330 of the latching member 33 can be received in or downwardly move through the hole 100 on the bottom wall 13 when the slider 30 is at an initial position. Then the slider 30 is pushed by the inserting card 5 to move forwardly and upwardly against the top surface of the rib 110 from the low front portion 111 to the high rear portion 111′, while the card 5 just moves forwardly. So, the locking portion 330 retained to the slider 30 moves upwardly relative to the card 5 and inserts into the cutout 51 to lock the card 5 with the slider 30. At the time, the slider 30 arrives the final position, the locking portion 330 faces to the low front portion 111, not the hole 100, so the slider 30 is kept in the cutout 51. When the slider 3 return to the initial position, the locking portion 330 faces the hole 100 again and release the locking to the card 5.
While a preferred embodiment in accordance with the present invention has been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present invention are considered within the scope of the present invention as described in the appended claims.
