As shown in Fig. 4-6, according to card connector 100 of the present invention, it comprises: an insulating body 110, which is provided with a slot 101, and be used for the storage card (not shown) of pegging graft; A pair of locking member 102, lay respectively at two ends of described slot 101, described locking member 102 is suitable between the off-position (as shown in Figure 5) of the locked position (as shown in Figure 4) of locking storage card and release storage card mobile, each locking member 102 has a grab 103, and described grab 103 breaks away from described slot 101 in that described locking member 102 is driven described storage card when described locked position moves to described off-position; With one group of first conducting terminal 1042, be arranged in the described slot 101, wherein said the first conducting terminal 1042 comprises several first power supply terminals and several signal terminals, wherein: described card connector 100 further comprises one group of second source terminal 1042, the resistance of described second source terminal 1042 is used for the electric energy that transmission is different from the first power supply terminal through-put power less than the resistance of described the first power supply terminal.
Advantageously, the cross-sectional area of described second source terminal 1041 is greater than the cross-sectional area of the first conducting terminal.Certainly, thus second source terminal 1041 also can use the larger material of conductance to obtain better conductive capability to have less resistance.
Advantageously, along on the longitudinal direction of described slot 101, the width of the width of described second source terminal 1041 and described the first power supply terminal 1042 is roughly the same.Like this, second source terminal 1041 is identical with the spacing between adjacent the first power supply terminal with spacing (pitch) between adjacent the first conducting terminal 1042.Thereby second source terminal 1041 can be arranged on the position between two ends of card connector 100, also can be arranged near the end of card connector 100.But, be arranged on when second source terminal 1041 near the situation the end of card connector 100, might not require the described width of the described width of described second source terminal 1041 and described the first power supply terminal 1042 roughly the same.

The below discusses near the situation in end that the first power supply terminal 1042 is arranged on card connector 100.Particularly, as shown in Fig. 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 that is in a locking member 102 of described off-position is crossed the described plane of second source terminal to limiting, and described grab 103 between the right second source terminal 1041 of described second source terminal and is interfered with any second source terminal 1041 of described second source terminal centering.
Although it should be noted that among Fig. 4-5 as an example of transformation DDR3 DIMM connector example design of the present invention to be illustrated,, technical scheme of the present invention also can be applied to other card connector.
The described second source terminal here to the plane that limits represent when hypothesis second source terminal 1041 when very thin, the plane that opposed a pair of second source terminal 1041 limits.Particularly, this plane also can represent the plane that the side S of opposed a pair of second source terminal 1041 limits, and the plane P that also can limit together for a pair of second source terminal 1041 symmetrical center line separately is as shown in Fig. 5-6.Here the purpose of the introducing of plane P be for restriction be in the off-position locking member 102 grab 103 and from the position relationship between its nearest a pair of second source terminal 1041, be used for representing that this grab 103 crosses this plane P and entered between its nearest a pair of second source terminal 1041, thus from prior art in grab can not enter into from different between its nearest a pair of opposed splicing ear.As shown in Figure 5, can also describe like this " grab 103 that is in a locking member 102 of described off-position is crossed the plane P of described second source terminal to limiting; and described grab 103 is between the right second source terminal 1041 of described the second splicing ear ", namely in Fig. 5, in the projection on the direction inside perpendicular to paper, be in the off-position locking member 102 grab 103 projection with exist overlapping apart from the projection of its nearest a pair of second source terminal 1041.
Because grab 103 can move to apart between its nearest a pair of second source terminal 1041, even between the how right terminal, can effectively utilize two end place's locking members 102 of slot 101 and the space between the immediate splicing ear, be the regional A that mentions in the background technology, thereby provide other power delivery path for card connector.
Can adopt the distance that strengthens grab 103 activities that supply locking member 102 between a pair of splicing ear 1041 to realize such scheme.Particularly, as shown in Figure 6, each second source terminal 1041 of described second source terminal centering has an a of pin section, a contact site c and is connected to a b of beam section between the described pin a of section and the described contact site c; And described second source terminal to described in the parallel to each other or almost parallel of the described beam b of section of second source terminal 1041, be in the grab 103 of off-position between the right b of beam section of described second source terminal.Like this, the splicing ear that uses in the prior art shown in the accompanying drawing 3 pair, can effectively increase the distance between the right second source terminal of second source terminal in the scope of activities of grab 103, thereby prevent that grab 103 from contacting with arbitrary second source terminal 1041 of second source terminal centering or interfere 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 section, and the end of contact site c is towards the described beam b of section that is connected with described contact site; Described contact-making surface 105 is used for forming with described storage card and electrically contacts, and the right described contact-making surface 105 of described the 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 to this.For example, the b of beam section can be cambered outwards shape, can further widen like this distance between the relative beam b of section.
The grab 103 that can also guarantee by the position of improving the right contact site of second source terminal locking member 102 not can with the second source termination contact.Particularly, in card connector, each conducting terminal has an a of pin section, a contact site c and is connected to a b of beam section between described pin section and the described contact site, and wherein, described contact site c has the contact zone that electrically contacts with described storage card; On the grafting direction of described storage card, the height h2 of the bottom land of the described slot of the contact zone of the second source terminal 1041 of described second source terminal centering distance is greater than the height h1 of the bottom land of the described slot of contact zone distance of the first conducting terminal 1042.Because the distance between the right contact site of conducting terminal is minimum, the position of improving the right contact site of conducting terminal, the grab 103 that just can expand locking member 102 conducting terminal between the activity space that does not contact with conducting terminal.In this scheme, the conducting terminal 1041 of the second conducting terminal centering can be the splicing ear shown in the accompanying drawing 3, can certainly be the splicing ear shown in the accompanying drawing 6.
It is pointed out that the contact zone here for example represents apart from the height of bottom land: form in the situation that line contacts with the contact terminal of storage card in the contact zone, this contact wire is to the distance of bottom land; In contact zone and situation that the contact terminal formation face of storage card contacts, the horizontal center line of contact-making surface is to the distance of bottom land.
Except designing shape and the position near the second source terminal of locking member 102, can also reduce the width perpendicular to described plane P of grab 103, try one's best so that move in the roughly centre position of grab 103 between opposed second source terminal, if precision is enough, this can effectively utilize two ends place's locking members 102 of slot 101 and the space between the immediate splicing ear equally, thereby provides other power delivery path for card connector.
Certainly, the described width that reduces grab 103 also can combine with the shape of second source terminal and the design of layout.
The second source terminal 1041 of above-mentioned second source terminal centering can provide other power delivery path for card connector 100.For example, this second source terminal 1041 can be avoided because card connector, for example 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, described at least one second source terminal is to comprising two second source terminals pair, and a second source terminal is near the end that is arranged in slot 101, and another second source terminal is near another end that is arranged in slot 101.
