Technical field
The present invention relates to the connecting plate of the flexible transmission low frequency signal of telecommunication in a kind of communication, the TT﹠C system, more particularly, the present invention relates to a kind of being mainly used in adopts polyimide material to make the connecting plate that flexible transmission connector realizes that electricity is interconnected between extension set in electronic applications communication, the observing and controlling rack.Can think, the present invention except that be used to adopt polyimide material make flexible transmission connector interface interconnected, can also be used for the interconnect architecture of other flexible board-like connecting interfaces.
Background technology
At present, connector quantity and cable that complete electronic set equipment uses are all very many, and self-organizing system, dispersed placement, the complex optimum poor performance.Especially structural parameters are big, rack and other electronic equipments such as interconnected observing and controlling capacious, carry out signal when being connected in lead and low frequency attachment plug, need bigger interconnected space, be the flexible transmission connector of base material with the polyimides at present, owing to can not satisfy the observing and controlling rack, length needs greater than 2 meters super large connector interface, have to be connected with the connector welding interconnected with carrying out signal with lead and low frequency attachment plug in module and the little extension set, adopt assembling gang socket--the interconnect architecture at random that-cable links to each other or disperses wire bonds to link to each other, this just gives the volume of airborne complete machine, weight, power consumption, electromagnetic compatibility, assembling, very big pressure has all been brought in aspects such as maintenance.Press for improved design and assembly pattern, study new signal transmission means, help the complete machine Reduction of Students' Study Load, improve the environmental suitability of electrical property and complete machine.
The document of delivering both at home and abroad is to be flexible substrate and the interconnects that base material is made with the polyimides basically, yet there are no to directly apply to interconnected application report between the interior extension set of complete machine.Pertinent literature and data also do not adopt the ladder interconnection technique to realize direct-connected record between flexible substrate and flexible substrate, interconnects and the interconnects.
Summary of the invention
Task of the present invention is that proposition is a kind of simple in structure, connects reliably, and convenient disassembly, structural parameters are few, the interconnected syndeton of the interconnected flexible cable transmission of the low frequency signal of telecommunication capacious.To solve present length greater than 2 meters interconnected problems of super large connector interface.
Above-mentioned purpose of the present invention can reach by following measure: the interconnected syndeton of the flexible cable transmission of a kind of low frequency signal of telecommunication, comprise, at least two flexible transmission connectors of dielectric substrate that have connecting interface, and the staging pack transmission connecting plate of forming up and down the pairing overlap joint at least by above-mentioned two flexible transmission connector laminations, it is characterized in that, on the interconnection region face of described combination of transmitted connecting plate overlap joint ladder, be provided with the interconnected contact of the linear array that links to each other with flexible cable, the interconnected contact of linear array on the corresponding upper and lower surface of each stratum is arranged and is formed the corresponding mutually rectangular lattice array that connects; The staging pack transmission connecting plate clamping of the above-mentioned overlap joint of pairing up and down is between last lower platen.
The present invention and existing lead, cable and interconnected the comparing of connector welding have following technique effect:
The present invention adopts at least two flexible transmission connector lamination combinations, form the staging pack transmission connecting plate interconnect architecture of pairing overlap joint up and down, realize low frequency signal of telecommunication transmission in the complete machine rack, replace in the existing complete machine rack to look at and carry out signal with low frequency attachment plug and be connected with lead, low frequency electricity, it is many not only to have reduced the interior interconnected cable physical magnitude of complete machine rack, and overcome interconnected at random, the defective that interconnected space is bigger.And have:
1) capacity is big, and volume is littler, and structural parameters are few.On the interconnected ladder of the corresponding upper and lower surface of each stratum of the present invention, different spacing is arranged the mutual corresponding interconnected contact of rectangular lattice array that connects that forms, not only its ladder quantity can increase and decrease arbitrarily as required, and interconnected contact dot matrix area, the size laid on each step, the interconnected number of connections of laying, spacing and arrangement mode can be carried out as required freely being provided with and freely be adjusted.The expansion greatly of the interconnected capacity of ladder has solved length greater than 2 meters interconnected problems of super large connector interface.The staging pack of pairing overlap joint up and down overlaps smoothly, and the volume that takes up room is little.
2) convenient disassembly.The present invention can connect by relying on the spiral shell load, has the metal platen of good fractionation and repetition assembly properties, and crimping ladder termination is two flexible connectors up and down, realize the interconnected and signal of telecommunication conducting of correspondence position tie point, for maintainability test provides convenience.
3) simple in structure, the location is reliable.Owing to be provided with location and installation crimping hole at last lower platen and flexible connector ladder connection termination interconnect location, therefore only need control location and installation hole, machining accuracy is laid in ladder less than 1/4th and connects on the end face, determine interconnected contact minimum spacing, after can guaranteeing assembling, each interconnected contact is corresponding to be connected, and short circuit can not occur misplacing, thereby improves the reliability of complete machine.
4) making is simple and convenient, and cost is low.Ladder termination interconnect architecture can be realized that pressing plate adopts better rigidity metal material machining to form by polyimides lamination and processing technology, and interconnected securing member adopts the standard connector, and whole ladder interconnection technique is realized cheap.
5) connect reliably.The present invention is by the elasticity and the insulating properties of polyimide material itself; On the contact wire of crimping salient point correspondence on the pressing plate of pairing, form at interval by polyimides and metal interconnection tie point, under the effect of power, the deformation of polyimide material generation elastic shrinkage has guaranteed that the metal interconnection tie point reliably contacts during crimping.
The present invention is applicable to and adopts complete flexible transmission connector to replace the flexible connector interface of conductor signal transmission interconnected in the complete machine racks such as communication, observing and controlling.
