The wires are arranged side-by-side in a row at an end of each wire, where a termination element is connected. The termination element has opposed major faces, with an array of first contacts on a first face, and an array of second contacts on the opposed face, each of the first contact being electrically connected to a corresponding second contact. Each of the central conductors of the wire elements is connected to a corresponding one of the first contacts. An electronic device may include circuit boards at each end, with contacts arranged for compressive contact with the second contacts. The termination element may be captured between a clamp and the board, with an elastomeric spring maintaining compression, and pinned holes in the termination element and board ensuring registration of the contracts.
Description
Invention field
The present invention relates to multiple conductor cable, be specifically related to the small dimension coaxial line.
Background of invention and general introduction
The restriction of used wire characteristic during data at a high speed and signal transfer rate are transmitted.For the electronic system with the discrete parts that is connected by soft multiple conductor cable, signal rate not only is subjected to the restriction of the used flexible cord character of this cable, also is limited by the jockey between this cable and each parts.
In high-speed applications, can adopt all high speed cables, comprise the line of high performance coaxial line, twisted-pair feeder or other configurations.Any cable of selecting for use has certain bandwidth or frequency performance, and can adopt Low Voltage Differential Signal (LVDS) to limit the switching noise that may produce electromagnetic interference to other electric functions.Though the bandwidth of cable has its maximum in theory, but in actual applications, bandwidth regular meeting strictly is subjected to the restriction of link between cable and the circuit board, otherwise common other used components and parts also can limit effective bandwidth in the corresponding system.The discontinuity of junction can cause reflection and damped oscillation between the dissimilar connectors, thereby the time of clock cycle needs to prolong.In addition, return difference can produce deflection during the transmission of different circuits, and this needs time expand to comprise the time range that the signal that sends out on each bar circuit arrives its destination equally.
Usually, each end that is connected cable between cable and components and parts need have connector.Connector can be connected to cable and easily such as on the parts such as circuit board.For needing cable and components and parts that the system of separability is arranged, each end of cable can comprise the connector component of two couplings, and one is connected to cut cable and another is connected on the circuit board.This class connector respectively produces some discontinuity poinies, and bandwidth constraints is arrived under the theoretical performance of cable.This discontinuity betides circuit board and a connector part junction, and herein, this coupling part is to be connected with corresponding other coupling parts cooperations and with cable.The build-up effect of these discontinuity poinies it is believed that and can make frequency bandwidth reduce to make an appointment with half in some cases.
Traditional connector also can make the high speed cable system enlarge markedly cost and volume except that meeting has influence on transmission performance.Such continuator must be installed on elements and parts board and the cable, and needs the cost skilled worker.Cable may be to be provided by different suppliers with circuit system part, respectively has the part of the connector that needs cooperation, makes mismatch become problem.In addition, the cables manufacturing merchant may have the user who specifies different tie points, requires to stock different parts.Manufacturing cost also will significantly increase, and could guarantee that each lead can be connected to the suitable contact place on each connector because this cable with numerous leads must carefully assemble.
The present invention has broken through all restrictions of prior art by the cable with many coaxial lines is provided.Every coaxial line has the centre drift that is surrounded by the insulating material sheath, and this sheath surrounds for conductive shielding part.These lines are embarked on journey side by side and are connected a terminal member in this in the one end.This terminal member has two relative interareas, row first contact is arranged on first face and row second contact is arranged on relative face, each first contact corresponding second contact that is electrically connected.Each centre drift of wire element is connected on corresponding first contact.Electronic device can comprise circuit board at each end, and having contact to be arranged on the plate can contact with second contact formation extruding.Above-mentioned terminal member can be clipped between a pressing plate and the foregoing circuit plate, keeps this compressing with elastomeric spring spare, aims at the pin hole assurance contact in the circuit board with terminal member simultaneously.
