Embodiment
Hereafter the present invention is further elaborated in conjunction with the accompanying drawings and embodiments.
In the power-supply controller of electric that the embodiment of the present invention provides, the integrated flexible interconnect method of coupling comprises:
Step one, according to the requirement of power-supply controller of electric Standard, circuit layout in designing power supply controller, and generate printed board structural information according to described circuit layout;
Step 1.1 obtains structural information
Described printed board structural information comprises size, installing hole size and relative position, also comprises printed board mount message and module and connector relative position information etc.As shown in Figure 1, according to the printed board housing hum pattern that circuit structure model graphics obtains.This figure comprises:
1) size information: the housing size obtained according to the information of actual unit, each edge lengths is respectively A ~ F.These information definitions printed board reality can wiring area, and device and line all can not exceed this scope.This frame size is slightly less than the size that structure is windowed, to ensure the matching of installing.
2) installing hole information: after the installation of printed board upper module, be arranged in the shell of power-supply controller of electric by the installing hole in printed board.The size of corresponding installing hole in printed board is obtained according to the size of the diameter of the connecting hole in power-supply controller of electric shell and relative position.Be respectively M1 ~ M8 for the installing hole of the present embodiment, aperture is φ x.Installing hole can adopt waist-shaped hole also can according to actual needs.What the substrate due to printed board in the present invention was selected is flexible material polyimides, so after the coefficient of elasticity considering polyimides and performance of expanding with heat and contract with cold, installing hole aperture larger than the aperture of connecting hole 5 ~ 10%, to offset structure processing and the accumulated error brought is processed in printed board, and the variations in temperature of power control box at Space-Work can be adapted to.
3) device installation site information: (information comprises connector specification for actual and relative position and module connector information according to each module of unit, connector is printed-circuit connector), draw each connector in printed board (with the private jack of connector in corresponding each module) relative position information.Connector J1 ~ J4, comprises for the structure hole of location and installation and the electrical aperture for being electrically connected.Structure aperture and electrical aperture, than actual connector mounting screw diameter and connector leg diameter large 5 ~ 10%, are convenient to install and offset the error of processing and bringing, reinforced assembly, and are adapted to the variations in temperature of power control box at Space-Work.
Step 1.2. design electrical connection
Complete above operation, show that information is drawn in complete printed board, carry out electrical connection design.As shown in Figure 2, according to electric connecting relation between each module that actual unit needs, carry out line design in printed board.
1) wiring area should keep certain safe spacing with printed board frame, is generally greater than 2mm, can effectively prevent improper electrical connection.
2) surrounding of structure installment hole and components and parts installing hole leaves safety zone, this region not cabling.Prevent printed board cabling and structure adjacent too near and be connected.
3) when having printed board cabling through connector electrical aperture, the safe spacing in cabling and hole should be set, avoid distance too little.
4) wiring takes into full account the parallel processing of signal, accomplishes not intersect as far as possible, simplified wiring process, reduces the wiring number of plies.
Step 2, making printed board
Make the substrate surface copper plating film that printed board is included in described printed board, according to described printed board structural information, described copper film is etched, form wiring.
Because electrical connection between disparate modules is by plate has connected up, printed board is without the higher device in position, also without the need to considering that conductor wiring bending process needs extra reserved operating space and the safe spacing between wire and construction panels, the design margin brought because of uncertain can be greatly reduced, effectively utilize space to greatest extent.
For ensureing assembling, reducing the rigging error brought because of mismachining tolerance, in the course of processing of printed board, taking the special processing of base material.Installing device (connector) part adopts rigid printed board base material, in order to ensure printed board installation strength; The PCB routing region be connected between connector adopts flexible parent metal, and as shown in Figure 3, Y1 ~ Y3 region, in order to offset mismachining tolerance.Flexible parent metal can flexibility, can well carry out flexible accordingly according to actual needs, ensure the smooth assembling of connector.
The welding of step 3, circuit is assembled with printed board
During printed board assembling, first by connector pre-installation, screw is fixed (ensureing not come off from printed board).The printed board and power-supply controller of electric shell that install combination hub are equipped with, check whether installing hole mates, the matching of socket and plug.Because connector electrical aperture and structure hole are all large than actual connector screw and pin footpath in printed board, socket moves within the specific limits in printed board.Can utilize during pre-installation and surplus counteracting mismachining tolerance is installed, ensure the smooth of installation.
This mount message is fixed after installing and locating by the assembly of printed board and connector and power-supply controller of electric shell.Consider operability, with electric iron by 1 of connector J1 ~ J3 and 12 means of spot welds, 1 and 8 means of spot welds of J4, ensure that the absolute position of combination hub in printed board.Then, taken off by assembly from structure, weld remaining contact, cleaning completes the assembling of assembly after checking.
The present invention's globality is in design considered, will electric and mechanical structure integrated design.To printed board be electrically connected, complete electrical connection by PCB routing.After printed board machines, according to the positional information of structure by the relevant position of connector welding in printed board, assembly carries out final assembly, first carry out pre-assembled, carry out complete assembling after completing with assembling, then complete the electrical connection of complete machine, then carry out necessary contact inspection and check, meet globality requirement, possess the condition of complete machine integration test.
Method of attachment provided by the invention, have employed flexible parent metal, greatly can reduce the weight of printed board; External form, form, fit, and function are integrated, carries out Electromechanical Design, can fitting operation be reduced, improve efficiency of assembling; PCB routing adopts planar conductor line, has more large area/volume ratio than round conductor, the diffusion of all easier heat of the passage of heat that printed board is simultaneously short.
According to the above, just the present invention can be realized.To the other changes and modifications that those skilled in the art makes in the case of without departing from the spirit and scope of protection of the present invention, be still included within scope.
Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; the Method and Technology content of above-mentioned announcement can be utilized to make possible variation and amendment to technical solution of the present invention; therefore; every content not departing from technical solution of the present invention; the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all belong to the protection range of technical solution of the present invention.
