Description
Technical field
The present invention relates to a kind of electronic installation and storage card connecting mechanism thereof, particularly relate to a kind of storage card connecting mechanism by magnetic drive.
Background technology
In general, the card connector of known mobile phone is taked the kenel of hot plug (hot swap) usually, wherein the hot plug connector of comparatively popularizing can be divided into two kinds of push type (push-push type) and drawer types (drawer type) again, the hot plug connector of above-mentioned push type has been disclosed in United States Patent (USP) U.S.6, in 572,392, the hot plug connector of drawer type then can be with reference to United States Patent (USP) U.S.6,805,589.
Yet above-mentioned pusher connector not only needs complicated clip mechanism, and must finish the insertion of storage card and withdraw from action by spring is set, and the spring that therefore gets off for a long time is easy to derive because of elastic fatigue the problem of reliability; On the other hand, though the drawer type connector can improve the problem of reliability,, therefore still have and withdraw from difficult shortcoming, and often cause the inconvenience in the use because it lacks automatic drawing-out mechanism.
Summary of the invention
Because the conventional store card connector has shortcoming, the invention provides a kind of storage card connecting mechanism, applicable to an electronic installation, it mainly comprises a circuit board, a chute, a bearing part, a magnetic element and an electromagnet.The foregoing circuit plate has an electrical connection section, and chute is formed on the circuit board.Above-mentioned bearing part is that magnetic element is arranged on the bearing part in order to the loading storage card.Above-mentioned electromagnet is electrically connected circuit board, and when electromagnet imposed one first magnetic force to magnetic element, bearing part was subjected to first magneticaction and enters chute, and makes storage card and electrical connection section conduct.When electromagnet effect one second magnetic force was on magnetic element, bearing part was subjected to second magneticaction and breaks away from chute, and makes storage card separate with electrical connection section.Storage card connecting mechanism also comprises a control switch, and described control switch is electrically connected circuit board, in order to the magnetic force of control electromagnet.
In a preferred embodiment, electromagnet has a solenoid and an iron core, wherein solenoid wound core periphery.
In a preferred embodiment, magnetic element is a permanent magnet.
In a preferred embodiment, electromagnet is arranged at the chute bottom.
In a preferred embodiment, first magnetic force is opposite with the direction of second magnetic force.
In order to make above and other objects of the present invention, feature and the advantage can more obvious easy to understand, below especially exemplified by preferred embodiment, and conjunction with figs. be elaborated.

Embodiment
At first with reference to Fig. 1, this figure is the schematic diagram of expression storage card connecting mechanism of the present invention, and described storage card connecting mechanism is applicable to an electronic installation, for example a mobile phone, digital camera or PDA etc.In the present embodiment, described electronic installation mainly comprises a storage card 31, a bearing part 32, a magnetic element 33, two guide blocks 34, an electrical connection section 35, a control switch 36, an electromagnet 37 and circuit boards 38.
As shown in Figure 1, magnetic element 33 is arranged on the bearing part 32, and wherein bearing part 32 can be in order to load storage card 31.In particular, guide block 34, electrical connection section 35, control switch 36 and electromagnet 37 all are arranged on the circuit board 38, and wherein control switch 36 can be by the circuit controling electromagnetism iron 37 on the circuit board 38.In addition, the bearing part 32 that is mounted with storage card 31 can enter by the guiding of guide block 34 in the chute 34 ' (as shown by arrows), and storage card 31 is combined with electrical connection section 35, and the system that is beneficial to carries out the action of access to the numerical data in the storage card 31.
In the present embodiment, the electromagnet 37 that is arranged on the circuit board 38 mainly is made up of a solenoid 371 and an iron core 312, wherein solenoid 371 is wound in iron core 312 peripheries, can form a specific magnetic fields by the electric current on the control solenoid 371, the present invention mainly is the magnetic effect by above-mentioned electric current, and then can be to the magnetic element on the bearing part 32 33 (a for example permanent magnet) effect one attraction or repulsive force.
Then in the lump with reference to Fig. 2,3, wherein Fig. 3 is the partial enlarged drawing of Fig. 2.When with storage card 31 when electrical connection section 35 on the circuit board 38 combines, the user can insert storage card 31 in the bearing part 32 earlier, then again bearing part 32 is pushed chute 34 '.At this moment, can drive electromagnet 37 generations one specific magnetic fields that is positioned at chute 34 ' end by pushing control switch 36, as shown in the figure, electromagnet 37 can produce the magnetic element 33 on the one first magnetic force F1 attraction left bearing part 32, bearing part 32 can utilize Magnetic force tracting and fully enter in the chute 34 ' like this, and storage card 31 also can arrive the location and form with electrical connection section 35 and to conduct.In Fig. 3, press control switch 36 back solenoid 371 and feed electric current, so just can form a pair of opposite magnetic pole at the both ends 3721,37 22 of iron core 371, utilize electromagnet 37 to produce one first magnetic force F1 (attraction), so can further bearing part 32 be sucked chute 34 ' inside to the magnetic element 33 of left.
Then in the lump with reference to Fig. 4,5, wherein Fig. 5 is the partial enlarged drawing of presentation graphs 4.On the contrary, when solenoid 371 is subjected to reverse electric current, the magnetic pole at iron core 371 left and right both ends 3721,3722 exchanges, 37 magnetic elements 33 (direction as shown by arrows) that produce one second magnetic force F2 (repulsive force) and then promote left of electromagnet this moment so just can force bearing part 32 to withdraw from chute 34 ' by magneticaction.In the present embodiment, the user can control the sense of current of solenoid 371 by pushing control switch 36, and then can make 37 pairs of magnetic elements of electromagnet 33 produce an attraction or repulsive force, is beneficial to inserting and withdrawing from of storage card.
Yet, even when above-mentioned solenoid 371 is not applied to electric current, also can be directly metal part and 33 of magnetic elements by electromagnet 37 produce spontaneous magnetic attracting forces, so similarly bearing part 32 can be sucked chutes 34 ' inside; On the contrary, when bearing part 32 being withdrawed from chute 34 ', can in solenoid 371, feed electric current, and produce a magnetic repulsive force, and then force bearing part 32 to withdraw from chute 34 ' by electromagnet 37 and magnetic element 33.
In sum, the present invention finishes inserting and withdrawing from of storage card by magnetic force, thus do not need to be provided with spring or other clip mechanism, thus the complexity that can simplify the internal structure of an organization; In particular, because magnetic force is to belong to contactless force, therefore compare with known push type or drawer type bindiny mechanism, the present invention can improve problems such as the component abrasion that caused because of permanent use and elastic fatigue effectively, and then can promote useful life.
Though the present invention discloses with preferred embodiment; but it is not that any those skilled in the art is not breaking away from design of the present invention and scope in order to qualification the present invention; all can make a little change and retouching, so protection scope of the present invention is defined with accompanying Claim.
