Abstract
The utility model aims to provide a high-current lead and a welding plate for a modular power supply. The problem that the input and output impedance of a power supply is required to be fully reduced and the utilization rate of the area of a circuit board is required to be improved because the input and output leads of a traditionally designed high-power and high-density power module bear high current is solved. In the high-current lead for the modular power supply, a welding neck is arranged on the end part of the lead; the tail part of the welding neck is oblate; and the height of the welding neck is equal to the thickness of a circuit board. A welding plate hole is formed in the middle of the welding plate matched with the high-current lead for the modular power supply; the diameter of the welding plate hole is slightly more than that of the welding neck; and the transverse shape of the welding plate hole is matched with the shape of the tail part of the welding neck. The high-current lead is a modular direct-current (DC)/DC power lead, is simple in appearance, is easy to process, is convenient to use without a special clamp or tool, is easy to mount and weld, and is small in the effective area of an occupied circuit board; and mass production is convenient to realize.
Description
Technical field
The utility model relates to a kind of module-power with big electric current input, output lead and pad.
Background technology
Develop rapidly along with electronic technology; The design that the miniaturization of electronic equipment and high density be integrated impels power supply develops towards the direction of light, thin, little, high efficiency and environmental protection, and traditional components and parts can't adapt to the densification designing requirement of electronic product gradually.For further promoting the performance and the integration density of electronic product, be to the constraint of the conventional thinking design of the design Gonna breakthrough of some Primary Components.For example the plug-in type components and parts have been replaced with surface mounting component; The integrated design of transformer and inductance; Promoted the power density of modular switch power supply greatly; The electric current that causes the input and output lead-in wire of power module to bear rapidly promotes, and the engineer can only constantly increase the diameter of lead-in wire for promoting the current carrying capacity of lead-in wire; Shorten the length of lead-in wire, with the internal resistance that reduces to go between.Large diameter lead-in wire will weld in the circuit board; Need intended diameter is bigger in the circuit board pad hole and pad; Also increase simultaneously the welding difficulty of lead-in wire, the more important thing is and weld a large amount of usable areas that large diameter lead-in wire has been sacrificed wiring board, compressed the space of other components and parts.
The great current lead wire of some external high-grade DC/DC power supplys need make special stand and anchor clamps could use, and only is fit to special-purpose, not general.
The utility model content
The purpose of the utility model provides a kind of module-power and uses great current lead wire; Input and output lead-in wire with the high power density power module that solves present design need bear big electric current, fully reduce the input and output impedance and the utilance that improves the wiring board area of power supply.
Another purpose of the utility model provides a kind of and module-power with the matching used pad of great current lead wire.
The utility model technical scheme is following:
A kind of module-power is used great current lead wire, and the end of lead-in wire is provided with the welding neck, and welding neck afterbody is oblate, and the height of welding neck equals the thickness of wiring board.
A kind of and module-power are with the matching used pad of great current lead wire, and the centre of pad is provided with the pad hole, and the somewhat larger in diameter in pad hole is in the diameter of said welding neck, and the horizontal shape in pad hole is suitable with the shape of welding the neck afterbody.
Lead-in wire will be used with the pad on the wiring board in the utility model; The bonding pad area that needs when welding this lead-in wire is very little, almost with the diameter of lead-in wire quite, firm welding, accurate positioning, and lead-in wire locks in the pad hole; Lead-in wire can not come off in the reflow welding process; Also can not pull from wiring board by lead-in wire, structure is also very firm, is convenient to again produce in batches.
The utility model is a modular DC/DC power supply lead wire, and succinct, the handling ease of profile is easy to use, and does not need special fixture or frock, and the effective area that is easy to install welding, busy line plate is little, convenient again batch process.Be fit to reflow soldering process welding, crest welding and manual welding, versatility is fine.

Fig. 2 is the grafting sketch map of the utility model module-power with great current lead wire and wiring board pad.
Embodiment
A kind of module-power is used great current lead wire, and the end of lead-in wire 1 is provided with welding neck 2, and welding neck afterbody 5 is oblate, and the height c of welding neck 2 equals the thickness of wiring board, and the thickness of welding neck afterbody 5 is less than the diameter of welding neck 2.
A kind of and module-power are with the matching used pad of great current lead wire, and the centre of pad 3 is provided with pad hole 4, and the somewhat larger in diameter in pad hole 4 is in the diameter of said welding neck 2, and the horizontal shape in pad hole 4 is suitable with the shape of welding neck afterbody 5.
Module-power is processed by copper rod with great current lead wire, and electroplate or gold, diameter can be 3.8mm～6.8mm, even bigger.Pad need be made metallized pads.
Use in the time of to go between, will weld neck afterbody 5 and insert in the pad holes 4, lead-in wire half-twist in pad hole 4; Welding neck 2 is stuck in pad hole 4, and can not come off can not be shifted yet, and is in position shown in Figure 2; Fill the slit in pad hole 4 more uniformly with scolding tin, wire bonds is accomplished.
