Abstract
An ejection mechanism for an electronic card connector includes a guiding structure (20), a lid (22), a slide rod (24), a slide block (26), an elastic element (27) and a retaining assembly (28). The guiding structure is formed in a housing of the connector. The guiding structure includes a recess (201) and an arcuate island (200) formed in a middle of the recess. A protrusion (144) is formed by the housing and protrudes in the recess. A second end (244) of the slide rod is slidably fitted in the recess.
Claims14
A card ejection mechanism for an electronic card connector, comprising:
- an elastic element;
- a slide block connecting with the elastic element, the slide block defining a fixing opening, the slide block being moved by the card and compressing the elastic element when the card is inserted into the connector;
- a slide rod having first and second ends, the first end being secured in the fixing opening of the slide block;
- and
- a guiding structure formed in a housing of the connector, the guiding structure including a recess and an arcuate island formed in a middle of the recess, a protrusion formed by the housing protruding in the recess, the second end of the slide rod being slidably fitted in the recess;
- wherein when an electronic card is fully inserted, the second end resiliently presses against the protrusion.
An electronic card connector comprising:
- a housing defining a receiving space therein for receiving an electronic card, and further defining a receiving cavity;
- a contact module secured in the housing;
- and
- ejection means received in the receiving cavity of the housing for facilitating ejection of the card, the ejection means including:
- an elastic element;
- a slide block connecting with the elastic element, the slide block defining a fixing opening, the slide block being moved by the card and compressing the elastic element when the card is inserted into the connector;
- a slide rod having first and second ends, the first end being secured in the fixing opening of the slide block;
- and
- a guiding structure formed in the housing of the connector, the guiding structure including a recess and an arcuate island formed in a middle of the recess, a protrusion formed by the housing protruding in the recess, the second end of the slide rod being slidably fitted in the recess.
An electrical card connector comprising:
- a housing with contacts therein;
- an ejection mechanism provided in the housing, said ejection mechanism including:
- a sea horse like guiding structure including a recess (201) with an arcuate island (200) formed in a middle of the recess (201), said recess (201) including a tail portion (202), a back portion (203), a top portion (204), a face portion (205), a jaw portion (206) and an abdomen portion (207) together constituting a continuous cyclic path;
- a slide block moveable relative to the housing;
- a slide rod with one end thereof receivably moving along said recess;
- and
- an elastic element constantly urging said slide block;
- wherein
- a tip of said tail portion (202) and the jaw portion (206) are two retaining positions for said end to hold said slide block in retaining positions relative to the housing;
- wherein
- said jaw portion (206) is located around a neck of a sea horse configuration of said sea horse like guiding structure, where said end of the slide rod is retainably located to define an inner position of the slide block relative to the housing, and alternately said end of the slide rod is retainably located at the tip of said tail portion (207) to define an outer position of the slide block relative to the housing.
