Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.

Should be appreciated that used hereinly such as " to have ", other element one or more do not got rid of in " comprising " and " comprising " term or the existence of its combination or interpolation.

The mainboard of current a lot of electronic product there are some structure electrical material, SIM card holder 4 in such as Fig. 2, T card deck 5 and so on, the feature of this kind of material is that often Area comparison is large, the space taking pcb board is also larger, and be all the position being distributed in pcb board edges of boards mostly, but effective pin is not but a lot, and pin all compares one side or both sides of concentrating on device, therefore the pcb board space below this kind of structure electrical material except PCB cabling, does not have other use except being sometimes used for.If when other positions of pcb board cabling space allow, can not cabling below this kind of structure electrical material, so now the space of PCB is just waste purely herein.In addition, the usual Area comparison of platelet of a lot of electronic product is little, but also be one side cloth member, and the content of the application mainly utilizes no pcb board space, the below of this kind of structure electrical material to carry out jigsaw between platelet and mainboard further, platelet is spliced to mainboard inside, make full use of the useful space on pcb board, promote the jigsaw utilance of pcb board further, reduce the cost of pcb board.

Conventional PCB jigsaw mode is platelet 3 jigsaw separately, and as shown in Figure 1, other one piece of platelet 2 and mainboard 1 are stitched together, as shown in Figure 2; Or platelet 3, platelet 2 and mainboard 1 are spelled on one block of large plate, now under the prerequisite ensureing the platelet 3 of equal number, platelet 2 and mainboard 1, whole jigsaw area must be greater than the area of jigsaw mode as shown in Figure 2.

Adopt the PCB jigsaw after the jigsaw mode of the application as shown in Figure 3, the PCB jigsaw of Fig. 3 and the PCB jigsaw area equation of Fig. 2, but the PCB jigsaw of Fig. 3 spells 4 PCB platelets 3 than the PCB jigsaw mode of Fig. 2 more, thus improve the jigsaw utilance of PCB mainboard further, reduce the cost of PCB jigsaw.

As shown in Figure 3, the utility model provides a kind of PCB jigsaw, comprising: at least two PCB mainboards 1, and it is spliced to form jigsaw main body mutually, and adjacent two PCB mainboards 1 are spliced by multiple dowel 11.Multiple deck 2, it is arranged on the edges of boards place of each PCB mainboard 1, periphery and the described PCB mainboard 1 of described deck 2 are fixed by pad solder, namely the side of deck 2 and PCB mainboard 1 are connected and fixed, instead of the bottom surface of deck 2 is direct and PCB mainboard 1 is fixed, thus reserving certain jigsaw space, described deck 2 is SIM card deck or T card deck.Wherein, the position that described PCB mainboard 1 contacts with the bottom surface of described deck 2 is hollow form, and to form hollow structure, a PCB platelet 3 is arranged on the hollow structure place of described PCB mainboard 1, hollow out by below PCB mainboard 1 upper blocking seat 2, form the splicing space of a PCB platelet 3.

In described PCB jigsaw, the one side that a described PCB platelet 3 is not provided with device contacts with the bottom surface of described deck 2 and arranges, and the back side of the SIM card deck on PCB mainboard 1 and a PCB platelet 3 are provided with one of device facing to same direction, facilitate paster.

In described PCB jigsaw, each hollow structure of described PCB mainboard 1 and the junction of PCB mainboard 1 are provided with multiple stamp hole 12, and multiple stamp holes 12 are dispersed in the periphery of hollow structure.

In described PCB jigsaw, between each hollow structure of described PCB mainboard 1 and the technique edges of PCB mainboard 1, be provided with multiple dowel 11, so that whole PCB jigsaw is fixing.

In described PCB jigsaw, described PCB mainboard 1 is also provided with multiple splicing hole 13, splicing hole major part is arranged on the periphery of PCB mainboard 1, and the 2nd PCB platelet 4 is arranged in described splicing hole 13.

Because a PCB platelet 3 is than the area point slightly of the SIM card deck 2 on PCB mainboard 1, and the one PCB platelet 3 are one side goods of furniture for display rather than for uses, what therefore adopt during jigsaw is a PCB platelet 3 is spliced to below SIM card deck 2 (PCB mainboard 1 hollows out below SIM card deck 2), simultaneously anti-jigsaw (namely a PCB platelet 3 has the device simultaneously opposite face of SIM card deck 2 on corresponding PCB mainboard 1), facilitates factory's paster.Due to the back side PCB mainboard 1 of a PCB platelet 3 having surface-mounted device SIM card deck 2 after such jigsaw completes, therefore when jigsaw two boards (or the technique edges on side) if between connection use traditional dowel 11 mode to connect, when so needing point plate after paster completes, inside PCB mainboard 1 when using board separator to divide plate, lower cutter divides plate can damage SIM card deck 2, therefore normally cannot divide plate.In order to head it off defect, ensure again the reliability between the one PCB platelet 3 and PCB mainboard 1 when paster, the scheme of the application is when jigsaw, connected mode between a PCB platelet 3 and technique edges still uses dowel 11, to ensure the reliability connected, what adopt between a PCB platelet 3 and PCB mainboard 1 inside is the connected mode of full stamp hole 12, after this mode can be cut off all dowels 11 of periphery when board separator divides plate, hand of using gently presses a PCB platelet 3 toward next, get final product normal separation the one PCB platelet 3 and PCB mainboard 1, the space on PCB mainboard 1 is made full use of when can either ensure jigsaw like this, the stability connected between each plate when can ensure again paster, ensure the exploitativeness and point plate yield that divide plate after paster completes simultaneously.

Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
