Abstract
A surface mounting structure of through hole components comprises a printed circuit board (PCB), a first fixing mount, a second fixing mount and a through hole component. The first fixing mount and the second fixing mount are both made of board type insulated high-temperature resistant materials. Surface mounting pads are preinstalled on the PCB. The first fixing mount is provided with grooves, and the shape and position of the grooves are consistent with those of the surface mounting pads on the PCB. The second fixing mount is provided with through holes, and the number, position and diameter of the through holes correspond to those of pins of the through hole component. The first fixing mount and the second fixing mount are attached to each other, and the through holes are positioned in the grooves. The pins of the through hole component are bent along the direction of the through holes after penetrating through corresponding through holes, and the pins are positioned in the grooves. The pins are soldered to corresponding pads on the PCB. The surface mounting structure of through hole components is convenient to operate and high in efficiency.
Description
Technical field
The utility model belongs to the pcb board welding technology field, specifically is a kind of straight cutting device Surface Mount mounting structure.
Background technology
In the PCB circuit design, the straight cutting alminium electrolytic condenser is a lot of as the common components mounting means, is horizontal installation, vertical installation basically, to survey vertical installation the most frequently used.The Application Design of paster alminium electrolytic condenser is also very ripe, and the Surface Mount form is also varied.For some specific industries (such as the electric bicycle controller industry); Application to the straight cutting alminium electrolytic condenser is very ripe; Many electrochemical capacitors factory can both give the electric bicycle controller straight cutting alminium electrolytic condenser of the supporting special use of design separately, but Surface Mount alminium electrolytic condenser factory can not provide the Surface Mount alminium electrolytic condenser that is suitable for mutually at present.Simultaneously, also run into similar problem for other straight cutting device.
Summary of the invention
In order to solve the problems referred to above that exist in the prior art, the utility model proposes a kind of straight cutting device Surface Mount mounting structure, comprises pcb board, first fixed mount, second fixed mount and straight cutting device; Said first and second fixed mount all is the resistant to elevated temperatures material of tabular insulation;
Be preset with the Surface Mount pad on the said pcb board;
Have groove on said first fixed mount, the Surface Mount pad is consistent on the shape of this groove and position and the pcb board;
Have through hole on said second fixed mount, the quantity of through hole, position and diameter are corresponding with quantity, position and the diameter of the pin of straight cutting device;
Said first and second fixed mount is fitted each other, and said through hole is in groove;
After the pin of said straight cutting device passed respective through hole, along the direction bending of groove, pin was in groove; Corresponding Surface Mount pad welding on pin and the pcb board.
Said first and second fixed mount is provided with corresponding alignment pin and location hole, and alignment pin is inserted in the location hole, and the height of alignment pin is not more than the degree of depth of location hole.
The shape of said first and second fixed mount is identical.
After adopting the utility model; Can be bonded at first fixed mount on the pcb board earlier; Be inserted in the straight cutting device in second fixed mount; To again first fixed mount and second fixed mount being fixed behind the pin shaping,, directly cross Reflow Soldering and get final product then first and second fixed mount group of straight cutting spare and the integral piece Surface Mount predeterminated position on pcb board that becomes.
Description of drawings
Fig. 1 is the sketch map of present technique scheme;
First fixed mount 1, second fixed mount 2, straight cutting electrochemical capacitor 3, alignment pin 4, location hole 5, groove 6.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present technique scheme is further specified as follows:
A kind of straight cutting device Surface Mount mounting structure comprises pcb board, first fixed mount, second fixed mount and straight cutting device; Said first and second fixed mount all is that (this material is to decide according to the requirement of processing to the resistant to elevated temperatures material of tabular insulation, can select kind a lot of in the prior art, does not further limit; Be preset with the Surface Mount pad on the said pcb board; Have groove on said first fixed mount, the Surface Mount pad is consistent on the shape of this groove and position and the pcb board; Have through hole on said second fixed mount, the quantity of through hole, position and diameter are corresponding with quantity, position and the diameter of the pin of straight cutting device; Said first and second fixed mount is fitted each other, and said through hole is in groove; After the pin of said straight cutting device passed respective through hole, along the direction bending of groove, pin was in groove; Corresponding Surface Mount pad welding on pin and the pcb board.Said first and second fixed mount is provided with corresponding alignment pin and location hole, and alignment pin is inserted in the location hole, and the height of alignment pin is not more than the degree of depth of location hole.The shape of said first and second fixed mount is identical.
This routine straight cutting device is the straight cutting electrochemical capacitor.
This example is a kind of fixed mount of design between straight cutting alminium electrolytic condenser and aluminum-base printed circuit board, satisfies both sides' good fit and uses.The straight cutting alminium electrolytic condenser is through simple pin shaping, and through fixed mount and aluminum-base printed circuit board good fit, and 2 of simple increases cooperate the fixing hole of usefulness just can realize locating the effect of adorning with counnter attack with fixed mount in the aluminum-base printed circuit board design.To different-diameter straight cutting alminium electrolytic condenser (in 6 kinds), optimize a few money fixed mounts (in 3 sections) and can satisfy electric bicycle controller electronic structure design application.
