The converter comprises a converter housing and a wire-harness pin-switch circuit, wherein the converter housing is provided with a wire inlet and a wire outlet. The two plug-type interfaces are connected with the wire-harness pin-switch circuit by the wire inlet and the wire outlet. The wire-harness pin-switch circuit is mounted in the converter housing to complete corresponding pin switch of the finished-vehicle wire harness and the ECU wire harness. The wire-harness conversion apparatus provided by the utility model has the advantages of simple structure, reasonable design, low maintenance cost, low fault rate and strong universality and can really simulate an operation state of a wet clutch in a transmission finished vehicle. The conversion apparatus can detect a friction performance and reliability of the clutch under a real operation condition and test results are relatively reasonable.
Description
Technical field
The utility model relates to a kind of wire harness conversion equipment, particularly relates to a kind of wire harness conversion equipment for vehicle motor car load wire harness and ECU communication conversion.
Background technology
At present, during car load coupling engine, need to carry out upgrading to engine, or needs are upgraded to the control ECU of engine simultaneously.But behind the engine upgrading, new car load wire harness aspect hardware aspect and information counterpart can't with original ECU communication; After the control ECU of engine upgraded, owing to adopt new E CU, the car load wire harness was original ECU communication wire harness, also can't carry out communication with new E CU aspect hardware aspect and the information counterpart.If above situation occurs, can only again make Novel wire harness, and the whole piece Novel wire harness is placed the outside ECU position of introducing driver's cabin of cabin cover.This work difficulty is very large, the phenomenon of wire harness and transducer wrong very easily occurs, and the external wire harness that causes easily of wire harness damages, and is unfavorable for maintenance, the problem such as can't test for a long time.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, the wire harness conversion equipment that working stability is reliable, loading and unloading are simple, cheap.In order to achieve the above object, the technical solution adopted in the utility model is: it comprises transducer, plug-in interface and plug-in interface, described plug-in interface is connected with the plug-in interface of car load wire harness, described plug-in interface is connected with the plug-in interface of ECU wire harness, described transducer comprises converter shell and wire harness stitch built-up circuit, described converter shell contains incoming line and line outlet, the plug-in interface is connected incoming line and is connected with wire harness stitch built-up circuit with line outlet with the plug-in interface, described wire harness stitch built-up circuit is positioned at converter shell inside, finishes the switching of car load wire harness and the corresponding stitch of ECU wire harness.The utility model has the advantages that: simple in structure, reasonable in design, maintenance cost is low, failure rate is low, highly versatile, but the operating state of real simulation wet clutch in the speed changer complete machine, can detect frictional behaviour and the reliability thereof of clutch under the real work operating mode, result of the test is more reasonable.
Description of drawingsFig. 1 is the utility model structural representation; Fig. 2 is the another kind of partial structurtes form of the utility model schematic diagram.
EmbodimentBelow in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.By Fig. 1-Fig. 2 as can be known, it comprises transducer 4 the utility model, plug-in interface 3 and plug-in interface 5, described plug-in interface 3 is connected with the plug-in interface 2 of car load wire harness 1, described plug-in interface 5 is connected with the plug-in interface 6 of ECU wire harness 7, described transducer 4 comprises converter shell and wire harness stitch built-up circuit, described converter shell contains incoming line and line outlet, plug-in interface 3 is connected with the plug-in interface and is connected with wire harness stitch built-up circuit with line outlet by incoming line, described wire harness stitch built-up circuit is positioned at converter shell inside, finishes the switching of car load wire harness and the corresponding stitch of ECU wire harness.Incoming line on the described converter shell and line outlet are positioned at the two ends of converter shell.Incoming line on the described converter shell and line outlet are positioned at the same end of converter shell.Described converter shell is divided into upper shell and lower house, through after the punch forming, is connected by screw formation.The utility model comprises transducer 4, plug-in interface 3 and plug-in interface 5, and plug-in interface 3 is connected with the plug-in interface 2 of car load wire harness 1, and plug-in interface 5 is connected with the plug-in interface 6 of ECU wire harness 7.Transducer 4 comprises converter shell and wire harness stitch built-up circuit, and converter shell contains incoming line and line outlet, and plug-in interface 3 is connected with the plug-in interface and is connected with wire harness stitch built-up circuit with line outlet by incoming line.Wire harness stitch built-up circuit is positioned at converter shell inside, finishes the switching of car load wire harness and the corresponding stitch of ECU wire harness.For example, the car load wire harness is the M78 system 64 needlework bundles of Unitive Semiconductor Taiwan C.And ECU is the 81 pin ECU of M788 system of Unitive Semiconductor Taiwan C, wherein there are 31 pins identical with the M788 system in the corresponding stitch of M78 system wire harness, and the definition of different stitch is received respectively on the definition position unsettled in 64 pins, makes new E CU can use former vehicle wire harness and engine to carry out communication.Incoming line on the converter shell and line outlet can be positioned at the two ends of converter shell, and as shown in Figure 1, the incoming line on the converter shell and line outlet also can be positioned at the same end of converter shell in addition, as shown in Figure 2.These two kinds of arrangement forms can be used on a selective basis according to the installing space size of wire harness conversion equipment.The processing and manufacturing form of converter shell has multiple, generally adopts the version of upper-lower casing, and upper-lower casing is connected by screw formation after passing through punch forming respectively.Also can be the mode machine-shaping of adopting plastic shaping.Operation principle of the present utility model is: new work engine ECU control mode and original engine control mode are contrasted circuit theory diagrams, find out different places, in wire harness stitch built-up circuit, corresponding wire harness stitch is coupled together, with the conversion of settling signal, then couple together the conversion of finishing wire harness with car load wire harness 1 and Engine ECU respectively by plug-in interface 3 and 2,5 and 6.
