Embodiment

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The schematic diagram of the jump ring that is used for the T-Flash storage card that Fig. 1 a-Fig. 1 d provides for the utility model.As shown in Figure 1a, this jump ring specifically comprises metal spacer 1, metal spring leaf 2, V-type groove 3.

Metal spacer 1 is the rectangle sheet metal, and the above has the optical locating point 11 for surface mounting technology (Surface Mounting Technology, SMT), is used for the location in SMT paster process.Metal spacer 1 can be to be (shown in Fig. 1 b, the 1c) of level or (shown in Fig. 1 d) of local perk.Metal spacer 1 is inhaled the counterweight effect of playing balance metal spring leaf 2 in the sheet process at SMT equipment suction nozzle, makes the suction sheet more firm.Adopt and be more convenient for after metal spring leaf 2 is mounted on the printed circuit board (PCB) (Printed Circuit Board, PCB) 4, metal spacer 1 being bent such as the design of metal spacer 1 local perk among Fig. 1 d.

Metal spring leaf 2 comprises the sheet metal of 8 elongate strip, be wholely set with metal spacer 1, and a parallel equally spaced side by metal spacer 1 is extended.Metal spring leaf 2 and metal spacer 1 adopt the same elastic metal material of shape memory characteristics that has, and metal spring leaf 2 is one-body molded by mould with metal spacer 1, and the relative position of 8 metal spring leafs satisfies the demand of technical standard of T-Flash.Metal spring leaf 2 comprises paster section 21 and shell fragment section 22.The lower surface of paster section 21 is jig 211, when being used for SMT and mounting and the pad on the pcb board 4 weld.The top of shell fragment section 22 contacts with hard contact on the T-Flash card 5, is used for fixedly T-Flash card 5, and plays the effect that is electrically connected between T-Flash card 5 and the pcb board 4.

There are one or a pair of V-type groove 3 up and down in the junction of metal spacer 1 and each metal spring leaf 2, is used to indicate bending and the position of the metal spacer 1 that fractures.By adopting the processing of V-type groove, make the metal thickness of junction very thin, be easy to bending, and the section on the metal spring leaf 2 after the metal spacer 1 that fractures does not stay burr.The position of V-type groove 3 can be positioned at the upper surface of metal spring leaf 2 shown in Fig. 1 b, perhaps be positioned at upper surface and the lower surface of metal spring leaf 2 shown in Fig. 1 c.

The metal spacer that Fig. 2 provides for the utility model process schematic diagram that fractures.Paster section 11 bends metal spacer 1 up and down along the direction of arrow among Fig. 2 after being mounted on the pcb board 4, until metal spacer 1 fractures from V-type groove 3, separates with metal spring leaf 2.Metal spring leaf 2 after the removal metal spacer 1 is 8 equally spaced elongated strip shaped sheet metals shown in Fig. 3 a-3b.

The device process of jump ring is: the suction nozzle of SMT equipment is drawn metal spacer 1 zone of jump ring and is got sheet, jump ring is positioned on the relevant position of pcb board 4 according to anchor point 11, the lower surface jig 211 of the paster section 21 of metal spring leaf 2 and solder joint on the pcb board 4 are welded, repeatedly bend up and down afterwards metal spacer 1, until metal spacer 1 separates with metal spring leaf 2 from 3 fractures of V-type groove.

When T-Flash card 5 inserts, shown in Fig. 4 a, T-Flash card 5 is inserted along the direction of arrow in the figure the top of metal spring leaf 2 by paster section 21 to shell fragment section 22 directions, until the hard contact 51 of T-Flash card 5 contacts with the end points of shell fragment section 22, shown in Fig. 4 b, T-Flash card 5 inserts fully.Shell fragment section 22 is pressed downward to paster section 21 near level at this moment.Because metal spring leaf 2 all is positioned at the downside of T-Flash card 5, so 2 of metal spring leafs take the area on the PCB 4 that T-Flash card 5 itself takies, and do not need to reserve for metal spring leaf 2 separately the area of extra pcb board 4, saved the space of pcb board 4.

When T-Flash card 5 is extracted, shown in Fig. 4 c, T-Flash card 5 is outwards extracted to the direction of paster section 21 by shell fragment section 22 along the direction of arrow in the figure, and after T-Flash card 5 was extracted fully, shell fragment section 22 returned to original angle with the angle angle of paster section 21.

Need to prove, in above-described embodiment, be illustrated take the jump ring that is used for the T-Flash card as the content of example to utility model, but application of the present utility model is not limited to the jump ring for the T-Flash card, is equally applicable to jump ring that other data cards use or other adopt jump ring to do in the jump ring design of electric connecting device.

The disclosed storage card jump ring of the utility model by increasing a metal spacer, makes jump ring be easier to the application surface mounting technology and mounts, and makes the metal spacer after mounting be easy to separate with metal spring leaf by the design of adopting the V-type groove.Jump ring is below pcb board places storage card, and structure is small and exquisite, and thin thickness does not take separately the area of PCB, saves the space.

Above-described embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the above only is the specific embodiment of the present invention; the protection range that is not intended to limit the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
