Description

A kind of embedded computer based on flexible PCB electric interconnection

Technical field

The utility model relates to embedded computer field, especially a kind of embedded computer based on flexible PCB electric interconnection.

Background technology

Embedded computer under current vehicle environment usually relates to the process of a large amount of integrated data and several functions interface need be provided to be used for carrying out the output of signal data, generally the transmission of these signals needs a large amount of cables and wire and cable connector, easily like this cause that the bonding wire difficulty of equipment is large, the production cycle is long, and cable can take a large amount of cabinet spaces, all bring very large difficulty to design and manufaction.Simultaneously in the automotive environment usually because rack, equipment are various, space layout is compact, interconnect cable is intensive, some racks even do not have special movable Wiring structure to connect with equipment, when the important module such as board and power supply need handling, change safeguard time can be very difficult, need a large amount of steps and time just can reach maintenance effects, and like this complete machine disassembled, be unfavorable for powering in the automotive environment, fix a breakdown.How to make the productibility of embedded computer internal electrical interconnections aspect can good and important module maintainability efficiently, become an important problem.

Summary of the invention

Technical problem to be solved in the utility model proposes a kind of embedded computer based on flexible PCB electric interconnection, ensures that the productibility of embedded computer internal electrical interconnections aspect can be got well and important module maintainability is efficient.

Technical solution of the present utility model is as follows:

Based on an embedded computer for flexible PCB electric interconnection, comprise flexible PCB, PCB backboard, PCB base plate, module board, static housing, active box, guide rail, movable chute etc.Electric interconnection between backboard with base plate is connected by flexible PCB, and the active box of computer cabinet and static housing are mechanically connected by guide rail and movable chute.

Flexible board PCB is inner can integrated a large amount of signal wire, significantly can reduce the cable wire of box house, save very large line space.

Module board, modular power source etc. can easily detach static housing with active box, can carry out rapidly loading and unloading and changing maintenance.

The beneficial effects of the utility model:

Embedded computer based on flexible PCB electric interconnection of the present utility model, adopts flexible PCB to carry out electric interconnection, significantly decreases the cable connection of box house, and the productibility of computing machine can be good; Simultaneously the important module such as module board, modular power source can carry out loading and unloading and changing rapidly, and maintainability performance is high.

Embodiment

Below with reference to the drawings and specific embodiments, the utility model is described in further details:

Embodiment 1:

As Figure 1-1, a kind of embedded computer based on flexible PCB electric interconnection, comprises flexible PCB, PCB backboard, PCB base plate, module board, static housing, active box, guide rail, movable chute etc.Interconnect bus between PCB backboard integration module board, the output port of the integrated user connector of PCB base plate, the electric interconnection between backboard with base plate is connected by flexible PCB.PCB base plate is on the static housing of computing machine, and PCB backboard, module board, modular power source etc. are on active box, and active box and static housing carry out mechanical attachment by guide rail and movable chute.

As shown in Figure 1-2, the two ends of flexible PCB are rigidity PCB, rigid plate are furnished with respectively the mezzanine connector of high density multi signal, and signal corresponding between two connectors carries out electric interconnection.The bending radius of PCB flexible portion will customize little as far as possible, must contraction more freely and expansion.

As Figure 1-3, the rotating shaft of movable chute is connected with wiring board by hook, link up with the damping washer that all there is teflon material at the upper and lower two ends of part be connected with rotating shaft, by screwing the decrement of screw adjustment damping washer, the damping due to rotation between rotating shaft and hook can be adjusted, make hook and can rotate a certain angle easily around the shaft with the wiring board of its rigid attachment.Wiring board leaves M3 screw hole, being used for the flexible portion of mounting structure to flexible board PCB is fixed and protects.

As Figure 1-4, the male of the mezzanine connector at flexible PCB two ends accesses the female of backboard and base plate respectively, and is equipped with application specific architecture part and is fixed connector and protects.Simultaneously the flexible portion of flexible PCB should leave enough length surpluses in the corner of movable chute, when making it launch along with movable chute or shrink, and distortion that can not be excessive thus cause and damage even fracture failure.Sometimes to be transferred to the number of signals of PCB base plate very many for module board calorie requirement, at this moment the two even flexible PCB of greater number can be adopted to carry out electric interconnection, shown in figure is with interconnection respectively between integrated a part of module boards of two pieces of backboards and output port, then the input port of one piece of flexible PCB access base plate is respectively installed at the output port of backboard, is finally transferred to user connector exports integrated for signal.Movable chute connects active box and static housing by the web joint at two ends; the chute of requirement activity simultaneously shrinks with the stroke launched basically identical with guide rail active strokes; guarantee that active box physical efficiency detaches the enough distances of static housing so that plug and maintenance modules board, modular power source etc., the approximate location that need pull out as Figure 1-1.

In sum, flexible board PCB based on the embedded computer of flexible PCB electric interconnection is inner can integrated a large amount of signal wire, can also adopt simultaneously two even many flexible PCBs carry out electric interconnection, significantly can reduce the cable wire of box house like this, save very large line space, the working time of a large amount of minimizing bonding wire of energy and assembling, the productibility of computing machine can be greatly improved; The inner important module board, modular power source etc. of simultaneous computer can easily detach the enough distances of static housing with active box, can carry out rapidly loading and unloading and changing maintenance, the maintainability performance height very of computing machine.
