Abstract
The invention discloses a card connector comprising an insulating body, a plurality of terminals held into the insulating body, a shielding cover buckled onto the insulating body to form an insertion space between the shielding cover and the insulating body, and a drawer base inserted into or pulled out of the insertion space. The card connector further comprises an electric permanent magnet. When the drawer base is inserted into the insertion space, a current in a first direction is applied to the electric permanent magnet, and the magnetic force of the electric permanent magnet is increased to absorb the drawer base. When a card withdraws, a current in a second direction opposite to the first direction is applied to the electric permanent magnet, and the magnetic force of the electric permanent magnet is decreased to release the drawer base.

[detailed description of the invention]
Refer to shown in Fig. 1 to Fig. 6, card connector 100 of the present invention is used for inserting electronic cards 200. Card connector 100 includes insulating body 1, be immobilizated in insulating body 1 some terminals 2, be fastened on insulating body 1 with formed between insulating body 1 insert space 11 cover lid 4 and the drawout chassis 3 plugged in described insertion space 11 in and the electric permanent magnetism 5 being contained in insulating body 1.
Insulating body 1 is provided with front, described insertion space 11 to house the receiving space 12 of described electricity permanent magnetism 5.
Described cover lid 4 upper surface be provided with opening 41, a pair buckling piece 42 of extending in opening 41 and be positioned at opening 41 rear and a pair elastic arm 43 of extending back.
Electric permanent magnetism 5 in first embodiment includes housing 51, soft magnetism the first magnet assembly 521 prepared, Hard Magnetic the second magnet assembly 522 prepared, is surrounded on outside the first magnet assembly 521 and the second magnet assembly 522 for alive coil 54 and a pair magnetic-conductance portion 53. Described housing 51 is box shaped, is provided with host cavity 513 and retaining wall 514. Described first magnet assembly 521 close to each other with the second magnet assembly 522 and together be contained in the host cavity 513 of described housing 51. The two ends of retaining wall 514 are provided with a pair slit 515. Described housing 51 two ends arrange a pair buckle protuberance 512 further and are positioned at a pair buckle slot 511 above the pair of buckle protuberance 512. A pair magnetic-conductance portion 53 is configured at described first magnet assembly 521 and with the second magnet assembly 522 two ends and is connected with the end of the first magnet assembly 521 with the second magnet assembly 522 respectively. First magnet assembly the 521, second magnet assembly 522, coil 54 and a pair magnetic-conductance portion 53 are contained in the host cavity 513 of housing 51. Magnetic-conductance portion 53 rear end extends back a pair slit 515.
Described covering makes described electricity permanent magnetism 5 load described receiving space 12 from top to bottom from described opening 41 after lid 4 is fastened on described insulating body 1. Described buckling piece 42 slips over described buckle protuberance 512 and is snapped in described buckle slot 511.
First magnet assembly 521 is connected with magnetic-conductance portion 53 to contrary and both ends with the magnetic pole of the second magnet assembly 522, and the magnetic line of force forms loop in first magnet assembly the 521, second magnet assembly 522 and a pair these four assembly of magnetic-conductance portion 53, and external magnetic force is little. During plug-in card, drawout chassis 3 inserts described insertion space 11. The electric current of first direction is passed in coil 54, change the magnetic pole of the first magnet assembly 521 to, make the pole of the first magnet assembly 521 and the second magnet assembly 522 to identical, then the magnetic line of force by magnetic-conductance portion 53 outwards and magnetic force strengthen, the elastic force of opposing elastic arm 43, can adsorb fixing by drawout chassis 3. Remain to during interruptive current keep magnetic-adsorption drawout chassis 3.
When moving back card, pass to the electric current with first direction opposite second direction change the pole of the first magnet assembly 521 to. Make first magnet assembly 521 pole with the second magnet assembly 522 to contrary. The magnetic line of force reverts to loop again in first magnet assembly the 521, second magnet assembly 522 and a pair magnetic-conductance portion 53, and external magnetic force diminishes. Elastic arm 43 can by drawout chassis 3 automatic spring.
Electricity permanent magnetism 5 simple in construction and the horizontal space of card connector 100 will not be taken. Electricity permanent magnetism 5 loads described receiving space 12 from top to bottom from described opening 41 and can be exposed to described receiving space 12 from without taking card connector 100 height space, meets miniaturization trend. The electric current that coil 54 only need to lead to different directions just can realize plug-in card or move back card, easy to operate and reliable.
Refer to shown in Fig. 7 and Fig. 8, the electric permanent magnetism 5 ' of the second embodiment includes magnetic group some groups adjacent. Each magnetic group includes first magnet assembly 521 ' similar to corresponding assembly in the first embodiment, the second magnet assembly 522 ', magnetic conductor 53 ' and coil 54 '. Adjacent and alignment the polarity of magnet assembly is identical. The operation principle of each magnetic group of the second embodiment is similar to the operation principle of the electric permanent magnetism 5 of the first embodiment. The magnetic force that the electric permanent magnetism 5 ' of the second embodiment produces is the superposition of the magnetic force that each magnetic group produces, thus magnetic force is higher.
The foregoing is only one embodiment of the present invention, be not all, of embodiment, the change of any equivalence that technical solution of the present invention is taked by those of ordinary skill in the art by reading description of the present invention, the claim being the present invention is contained.
