Embodiment
Be described below in detail the embodiment of exemplary of the present invention, the example of embodiment is shown in the drawings, and wherein same or analogous label represents same or analogous element.Below with reference to the accompanying drawings the embodiment described is exemplary, is intended to explain the present invention, and can not be interpreted as limitation of the present invention.
As shown in figs. 4-6, according to card connector 100 of the present invention, it comprises: an insulating body 110, which is provided with a slot 101, for grafting storage card (not shown); A pair locking member 102, lay respectively at two ends of described slot 101, described locking member 102 is suitable for moving between the locked position (as shown in Figure 4) and the off-position (as shown in Figure 5) of release storage card of locking storage card, each locking member 102 has a grab 103, and described grab 103 drives described storage card to depart from described slot 101 when described locking member 102 is moved to described off-position from described locked position; With one group of first conducting terminal 1042, be arranged in described slot 101,
Wherein said first conducting terminal 1042 comprises several first power supply terminals and several signal terminals, wherein: described card connector 100 comprises one group of second source terminal 1041 further, the resistance of described second source terminal 1041 is less than the resistance of described first power supply terminal, for transmitting the electric energy being different from the first power supply terminal through-put power.
Advantageously, the cross-sectional area of described second source terminal 1041 is greater than the cross-sectional area of the first conducting terminal.Certainly, second source terminal 1041 also can use the larger material of conductance to have less resistance thus to obtain better conductive capability.
Advantageously, along on the longitudinal direction of described slot 101, the width of described second source terminal 1041 is roughly the same with the width of described first power supply terminal 1042.Like this, the spacing (pitch) between second source terminal 1041 and the first adjacent conducting terminal 1042 is identical with the spacing between adjacent first power supply terminal.Thus second source terminal 1041 can be arranged on the position between two ends of card connector 100, near the end that also can be arranged on card connector 100.But, when near the end that second source terminal 1041 is arranged on card connector 100, might not require that the described width of described second source terminal 1041 is roughly the same with the described width of described first power supply terminal 1042.
Advantageously, the electric current that described second source terminal is suitable for conducting is greater than the electric current that the first power supply terminal transmits, according to one embodiment of present invention, described first power supply terminal is suitable for the electric current of conduction 0.5 ampere, and described second source terminal is suitable for the electric current of conduction 1.5 amperes.
Discuss the situation near end that the first power supply terminal 1042 is arranged on card connector 100 below.Particularly, as shown in figs. 4-5, described one group of second source terminal 1041 forms at least one second source terminal pair, the second source terminal 1041 of a described second source terminal centering is opposite each other in slot 101, the grab 103 being in a locking member 102 of described off-position crosses a described second source terminal to limited plane, and described grab 103 is not interfered with any one second source terminal 1041 of described second source terminal centering between the second source terminal 1041 that described second source terminal is right.
Although it should be noted that in Fig. 4-5 and be illustrated design of the present invention to transform DDR3 DIMM connector, technical scheme of the present invention also can be applied to other card connector.
Here described second source terminal represents when supposing that second source terminal 1041 is for time very thin, the plane that a pair opposed second source terminal 1041 limits limited plane.Particularly, this plane also can represent the plane that the side S of opposed a pair second source terminal 1041 limits, plane P that also can be limited together for the symmetrical center line that a pair second source terminal 1041 is respective, as shown in figures 5-6.Here the object of the introducing of plane P be for limit be in the locking member 102 of off-position grab 103 and from the position relationship between its a pair nearest second source terminal 1041, be used for representing that this grab 103 is crossed this plane P and entered between its a pair nearest second source terminal 1041, thus can not enter between the opposed splicing ear of its nearest a pair different from grab in prior art.As shown in Figure 5, can also describe like this " grab 103 being in a locking member 102 of described off-position crosses described second source terminal to limited plane P; and described grab 103 is between the second source terminal 1041 that described second splicing ear is right ", namely in Figure 5, in projection on the direction inside perpendicular to paper, the projection being in the grab 103 of the locking member 102 of off-position exists overlapping with the projection of a pair second source terminal 1041 nearest apart from it.
Because grab 103 can move between a pair second source terminal 1041 nearest apart from it, between even more multipair terminal, the space between two end locking members 102 of slot 101 and immediate splicing ear can be effectively utilized, namely the region A mentioned in background technology, thus provide other power delivery path for card connector.
The distance of grab 103 activity for locking member 102 between increasing a pair splicing ear can be adopted to realize such scheme.Particularly, as shown in Figure 6, each second source terminal 1041 of described second source terminal centering has a lead portion a, a contact site c and is connected to a beam portion b between described lead portion a and described contact site c; And described second source terminal to described in the described beam portion b of second source terminal 1041 parallel to each other or almost parallel, be in the grab 103 of off-position between the beam portion b that described second source terminal is right.Like this, the splicing ear pair used in the prior art shown in accompanying drawing 3, effectively can increase the distance between the right second source terminal of second source terminal in the scope of activities of grab 103, thus prevent grab 103 from contacting with arbitrary second source terminal 1041 of second source terminal centering or interfering in moving process.
As shown in Fig. 4,6, the contact site c of described each splicing ear 1041 of second source terminal centering is bent to form arc contact surface 105 from described beam portion, and the end of contact site c is towards the described beam portion b be connected with described contact site; Described contact-making surface 105 is for forming electrical contact with described storage card, and the right described contact-making surface 105 of described second splicing ear toward each other.
Certainly, be not in contact with it in moving process as long as can realize grab 103, the shape of second source terminal 1041 is not limited thereto.Such as, beam portion b can be cambered outwards shape, can widen the distance between relative beam portion b so further.
Can also be ensured by the position of improving the right contact site of second source terminal locking member 102 grab 103 can not with second source termination contact.Particularly, in card connector, each conducting terminal has a lead portion a, a contact site c and is connected to a beam portion b between described lead portion and described contact site, and wherein, described contact site c has the contact zone with described storage card electrical contact; On the grafting direction of described storage card, the contact zone of the second source terminal 1041 of described second source terminal centering is greater than the height h1 of contact zone apart from the bottom land of described slot of the first conducting terminal 1042 apart from the height h2 of the bottom land of described slot.Because the distance between the contact site that conducting terminal is right is minimum, improve the position of the right contact site of conducting terminal, the grab 103 just can expanding locking member 102 conducting terminal between not with the activity space of conductive terminal contacts.In this scheme, the conducting terminal 1041 of the second conducting terminal centering can be the splicing ear shown in accompanying drawing 3, can certainly be the splicing ear shown in accompanying drawing 6.
It is pointed out that the height of contact zone distance bottom land here such as represents: when the contact terminal of contact zone and storage card forms linear contact lay, this contact wire is to the distance of bottom land; When contact zone contacts with the contact terminal forming surface of storage card, the horizontal center line of contact-making surface is to the distance of bottom land.
Except designing shape and the position of the second source terminal of close locking member 102, the width perpendicular to described plane P of grab 103 can also be reduced, make the roughly centre position of grab 103 between opposed second source terminal move as far as possible, if precision is enough, this can effectively utilize the space between two end locking members 102 of slot 101 and immediate splicing ear equally, thus provides other power delivery path for card connector.
Certainly, the described width reducing grab 103 also can combine with the design of the shape of second source terminal and layout.
The second source terminal 1041 of above-mentioned second source terminal centering can provide other power delivery path for card connector 100.Such as, this second source terminal 1041 can be avoided because card connector, such as DDR3 DIMM connector power supply terminal lazy weight and the power supply problem that causes.
As shown in Figure 4, described card connector 100 can be DDR DIMM connector.Alternatively, at least one second source terminal described is to comprising two second source terminals pair, and second source terminal is near the end being arranged in slot 101, and another second source terminal is near another end being arranged in slot 101.
