Description
2~s6n~0 VEHICLE WIRING HARNESS WITH WIRING HARNESS CONNECTORS
Backaround of the Invention The invention relates to a wiring harness for a motor vehicle with at least one cab wiring harness connector that can be fastened to the vehicle cab, wh~se poles can be connected electrically with electrically powered devices, operating and instrumentation equipment in the vehicle cab and with at least one further wiring harness connector connected to the cab wiring harness connector, whose poles are connected to electrical accessories of a vehicle component such as the engine or transmission.
It is known to connect wiring harnesses of various vehicle components with each other by means of wiring harness connectors. Usually, the wiring harness connectors are configured as coaxial connectors which contain a multiplicity of connector elements. Sealing of the coaxial connectors with respect to the wire bundle carried through a flexible conduit is relatively costly in view of the difference in their diameters. Furthermore, the transmission of higher currents is difficult due to the relatively thin connector elements. A
further disadvantage of the known vehicle wiring harnesses is the poor accessibility of the main fuses, the high current relays and the connections for an external battery.
Summary of the Invention Accordingly, an object of this in~ention is to provide a wiring harness of the type described above in which the problems and disadvantages noted are overcome by a simple design that is easily assembled.
These and other objects are achieved by the present invention wherein at least one main fuse and/or a high current relay and terminals for connection for an external battery are integrated into the housing of the cab wiring harness connector and/or into the housing of the further wiring harness connector. The plug in connection between one or more wiring harnesses is configured as a power distribution center.
Preferably, at least one connecting arrangement is integrated into the plug-in connection formed by the cab 2~3~
wiring harness connector and the further wiring harness connector, which operates as the positive pole for the selective connection of an external battery and is electrically connected by at least one fuse integrated into the plug-in connection to the positive pole of the vehicle battery. The positive pole is preferably pin-shaped.
Preferably, the plug-in connection is mounted in an easily accessible location of the vehicle, for example, underneath the floor plate of the vehicle cab, between the steps. As a result, the main fuses, the high current relays and, above all, the positive pole of the external battery are easily accessible.
In addition to the positive pole, a grounding pole can also be integrated into the plug-in connection formed by the cab wiring harness connector and the further wiring harness connector, so that both connections for an external battery are located close together.
The connection arrangements are preferably designed so that, in addition to their original purpose as connections for an external battery, they can simultaneously operate to attach at least one of the wiring harness connectors to the vehicle chassis or to another wiring harness connector. For example, the grounding pole may be used as an attaching bolt to attach the cab wiring harness connector to the vehicle chassis, and the positive pole may be used as an attaching bolt to attach the further wiring harness connector to the ca~ wiring harness connecter. The positive pole, which is in direct contact with a connection to each of the main fuses (for example, for the cab electrical system and the engine electrical system) may be designed so that it is used for the attachment of the main fuses in addition to its use for the external battery, the connector attachment and the transmission of the entire power - supply for the cab and the entire power supply for the engine.
The grounding pole may be used ~or the connector attachment in addition to its use as a connection for an external battery.
Preferably, the wiring harness connectors are configured as flat components that can be connected together by inserting ;2~9~
one into the other. Each wiring harness connector may consist of a shell-shaped upper part and a shell-shaped lower part which engage each other with their surrounding facing edges in a labyrinth seal and which can be snapped into each other with a detent device~ This assures a simple assembly and a junction that is tight against water spray.
The wiring penetration opening is preferably formed by cylindrical half shells extending from each of the shells, which correspond to each other. A surrounding groove is provided in the interior of each cylindrical half shell into which a sealing element may be inserted to seal the wiring penetration opening or a fastening device may be applied.
According to a preferred embodiment of the invention, the power distribution center is primarily the main separating point between the cab on the one hand and the engine and transmission on the other hand. Preferably, it contains the main fuse for the entire cab electrical system, the main fuse for the entire engine electrical system, high current relay for the intake air pre-heater, the starter pull-in coil and connecting terminals for an external battery.
The power distribution center according to the invention can fulfill all the requirements imposed on an agricultural tractor or any other agricultural or utility vehicle:
1. Safety during start with external power.
2. Safety of cab electrica3 system by main fuse protection.

Detailed Description Referring to Figs. la, lb, 4 and 5, an agricultural tractor shown in dotted lines includes front wheels lO, rear wheels ~2 and a vehicle cab 14. Under the floor plate 15 of the cab 14 between the side spars 1~, 18 of the right step of the tractor, a cab wiring harness connector 20 is attached in an easily accessible location. The cab wiring harness connector 20 is the termination of a cab wiring harness 22 through which various electrical devices, operating and instrumentation units in the vehicle cab 14, such as fuse and relay boxes 24, instrument panel components 2~, differential lock switches 28 and power lift controls 30 are connected electrically with the poles of the cab wiring harness connector 20. A grounding cable 32 connects the floor plate 15 of the cab 14 with the engine bloc~ 34, which, for its part, is connected to the negative pole of the vehicle battery o (not shown). Studs 36, 38, 40, 42, 44, projecting downward, are weided to the floor plate 15 of the cab 14 and are used to attach the cab wiring harness connector 20 and the grounding cable 32.
The cab wiring harness connector 20 shown in Fig. lb includes a generally flat, shell-shaped upper part 46 and a flat, shell-shaped lower part 48. The upper part 46 has a surrounding edge 50 which projects downward. As best seen in Fig. 5, the edge 50 is provided with a downward opening groove 52 which receives the upward-projecting edge 54 of the lower part 48 when the connector 20 is assembled. The upper edge 54 is provided with detent projections 56 that engage corresponding recesses 58 in the edge 50 of the upper part 46 when the lower part 48 is attached. The junction between the upper part 46 and the lower part 48 forms a labyrinth seal which prevents the entry of water spray and dirt into the interior of the connector 20.
The upper part 46 includes a half cylindrical tube portion 60 which mates with a half cylindrical tube portion 62 formed in the lower part 48 to form a wiring opening. Grocves 64, 66, are formed within the wiring opening. One of the grooves receives an O-ring (not shown) which seals the connector housing against a flexible conduit (not shown), in which the electric wiring of the wiring harness 22 is carried.
The other groove receives a clamping ring (not shown) for the mechanical attachment of the flexible conduit. A bayonet ring 68 may be mounted on the assembled tube portions 60, 62 to retain the upper part 46 and the lower part 48 together and to clamp the flexible conduit (not shown) therebetween.
As best seen in Fig. 4, the lower part 48 contains three multi~pole connector units 70, 72, 74, each of which contains several chambers that accommodate sleeve contacts. The contacts are crimped to the free ends of the electric lines of the cab wiring harness 22 and inserted into the chambers so as to engage a detent. Two connector units 70, 72 provide a conne~tion with the engine wiring harness 76 and together contain twenty-four slee~e contacts. The third connector unit o 74 provides the connection with the transmission wiring harness 78 and contains forty sleeve contacts.
A bolt 82 extends through an opening 80 which extends through the bottom region of the lower part 48. The bolt 82 together with a washer 84 and a nut 86 is used to secure electrically a wiring connector 88 within the connector 20 and to the cab main fuse 90 which is mounted below and on the outside of the connector 20. The wiring connector 88 is connected to the fuse and relay boxes 24. The cab main fuse 90 is preferably a 125 amp. ceramic fuse which protects the entire cab electrical system. A spacer bushing 92 is mounted between the cab main fuse 90 and the underside of the connector 20 and provides the necessary free space for the cab main fuse 90.
In order to assemble the cab wiring harness connector 20, the connector contacts of the cab wiring harness 22 are initially inserted into the chambers of the connector units 70, 72, 74 and the wiring connector 88 and the cab main fuse 90 is secured to the lower part 48 by the bolt 82. The cab wiring harness 22, enclosed in a flexible conduit, is inserted between the opening formed by half cylindrical tubes 60, 62.
A hexagonal nut 9~ is inserted into a hexagonal recess 96 in the inner surface of the lower part 48. Now the upper part 46 and the lower part 48 are snapped together. At the same time a tube-shaped projection 98 (see Fig. 5) within the upper part 46 covers the hexagonal nut 94 and prevents it from escaping from the hexagonal recess 96. An internal hexagonal recess 100 in the upper part 46 covers the hexagonal head of the bolt 82 and prevents the bolt 82 from being turned. As a result, the cab main fuse 90 can be removed and replaced without the need for opening the connector 20.
In order to secure the cab wiring harness connector 20 to ~he vehicle cab 14, it is raised from below to the floor plate 15 so that the studs 38, 40, 42, 44 extend through corresponding bores in the upper par~ 46 and the lower part 48. These are secured by washers 102 and nuts 104 tightened on the studs 38, 40, 42, 44. Now a grounding attachment pin ~c~
106, which is provided at its one end with an internal thread 107 and with a hexagonal shape at its other end, is inserted through an opening 109 in the cab wiring harness connector 20 and is fastened to the stud 40. A collar 108 of the grounding attachment pin 106 is in contact with the underside of the cab wiring harness connector 20 and forces it against the floor plate 15 of the vehicle cab 14.
The grounding attachment pin 106 thereby performs two functions. On the one hand, it fastens the cab wiring harness ~0 connector 20. On the other hand, it electrically grounds the vehicle cab 14 by its metallic connection with the floor plate 15.
Referring now to Figs. 2a and 2b, the lines of the electrical accessories of the engine 110, for example, the generator 112, the tachometer 114, the air pre-heater 116, the fuel pre-heater 118, the starter 120, the temperature sensor 122 and the oil pressure gage 124, are combined in an engine wiring harness 76 and terminate in an engine wiring harness connector 12 6.
The engine wiring harness connector 126 is configured similar to the cab wiring harness connector 20, and similarly contains an upper part 128 and a lower part 130, which engage each other in a labyrinth junction for protection against dust and water spray, snap into each other in a detent and are provided with a wiring penetration opening that consists essentially of two cylindrical half shells 132, 134 and a bayonet ring 136. The upper part 128 encloses two connector units 138, 140, that correspond in size to the connector units 70, 72 of the cab wiring harness connector 20 and whose tota~
of twenty-four pin contacts projecting upward can be inserted into the corresponding sleeve contacts of the connector units 70, 72. The pin contacts of the connector units 138, 140 are connected to the electric wires of the engine wiring harness 76.
In addition, two four-pole plug-in connectors 142, 144 are arranged in the upper part 12~, whose contacts on the underside of t~e plug~in connectors (that is, the interior of ~3~ 0 the engine wiring harness connector 126) are connected to wires of the engine wiring harness 76 and on whose outer side, Yisible in Fig. 2, relays 146 can be attached. The relays 146 are a 70 amp. starter relay and a 70 amp. relay for the intake air pre-heater arrangement.
On its upper, outer side, the engine wiring harness connector 126 supports an engine main fuse 150 that protects the entire engine and starter electrical system. This is an B0 amp. ceramic fuse. The engine main fuse 150 is attached to the engine wiring harness connector 126 in similar manner to the above described attachment of the cab main fuse 90 to the cab wiring harness connector 20. This attachment uses a bolt 152, whose hexagonal head engages a hexagonal recess 154 in the inner wall of the lower part 130 to prevent its rotation, a spacer bushing 156, a washer 158 and a nut 160. The bolt 152 is used to attach the engine main fuse 150 as well as to attach and connect electrically wiring connection 161 arranged within the engine wiring harness connector 126. The wiring connection 161 is directly connected to the connection 163 of the starter 120 which, for its part, is connected to the positive pole of the vehicle battery.
The assembly of the engine wiring harness connector 126 is similar to that of the cab wiring harness connector 20 in that initially the connector units 138, 140 and plug-in connectors 142, 144 are inserted and connected electrically with the wires of the engine wiring harness 76. The hexagonal head of the bolt 152 is inserted into the hexagonal recess 154 and the spacer bushing 156 is applied. Then the positive pole attaching pin, described further below, and the two spacer 3~ bushings 184, 186 are assembled. Then the upper part 128 and the lower part 13~ are snapped together and the bayonet ring 136 is applied. The collar 187 of the positive pole attaching pin 182 secures this against escape from the engine wiring harness connector 126.
As best seen in Fig. 4, the engine wiring harness connector 126 can be attached to the cab wiring harness connector 20 in such a way that the upper side of the upper 2~it~0 part 128 of the engine wiring harness connector 126 overlaps a portion of the underside of the lower part 48 of the cab wiring harness connector 20 and the contact of the connector units 70 and 138 as well as 72 and 140 are inserted into each other. In order to provide the necessary free space for the relays, the lower part 48 of the cab wiring harness connector 20 contains a chamber 162 that opens downward. The attachment is made by a bolt 164 that is inserted from below into through holes 166, 168 in the engine wiring harness connector 126 and is threaded into a nut 167 which is retained in the upper part 46 of the cab wiring harness connector 20. To avoid any consequent deformation of the lower part 130 and the upper part 128 of the engine wiring harness connector 126 the through hole 166 extends within a ramp 170 that is part of the inner side of the lower part 130 and is supported on the inner side of the upper part 128. The bolt 164 is secured against loss by a washer 169 and a retaining ring 171 to the engine wiring harness connector 126. The interaction of the washer 169 and retaining ring 171 assists during disassembly of the wiring harness connector in releasing the relatively high contact forces that join the connector units 70, 138, 72, 140.
The lower part 48 of the cab wiring harness connector 20 is provided with an outer, surrounding groove which can accept a seal ring 172 which seals the joint between the cab wiring harness connector 20 and the engine wiring harness connector 126 against water spray. Furthermore, the engine wiring harness connector 126 contains through bores 174, 176, through which the grounding attachment pin 106 extends in the assembled condition.
Further, through bores 178, 180 in the engine wiring harness connector 126 accept the positive pole attaching pin 182 which can be threaded into the hexagonal nut 94 which is retained in the lower part 48 of the cab wiring harness connector 20. Two spacer bushings 184, 186 provide proper spacing and may be configured identical to the spacer bushings 92, 156. ~he positive pole attaching pin 182 si~ultaneously connects the free connections of the cab main fuse 90 and the o - engine main fuse 150 to each other. In addition, it is used, along with the bolt 164, to secure the engine wiring harness connector 126 to the cab wiring harness connector 20.
As a result, the positive pole attaching pin 182 connects the positive pole of the vehicle battery with the power supply wire of the vehicle cab 14, in that a connection is established between the vehicle batter~, the connection 163 of the starter 120, the wiring connection 161, the bolt 152 of the engine main fuse 150, the positive pole attaching pin 182, the cab main fuse 90, th~ bolt 82 and the wiring connection 88 which is connected to the power supply wire of the vehicle cab ~4.
The grounding attaching pin 106 and the positiv~ pole attaching pin 182 extend downward from the lower part 130 of the engine wirin~ harness connector 126 and are provided with a hexagonal shape in the projecting region. The projecting regions are protected at the side by a side wall 188. On th~
underside of the lower part 130 a pole cover door 1~0 is attached so as to pivot and to protect the two atta~ing pins 106, 182 from below. The pole cover door lg0 permits access to the attaching pins 106, 182, so that cables, not shown, of an external battery can be connected to the attaching pins 106, 182.
Referring now to Fig. 3a, the transmission 192 of the agricultural tractor is indicated in dotted lines. The lines of the electrical accessories of the transmission 192, for example, the differential locking valve 194, the ~orce measuring pins 196, the mechanical front wheel drive (MFWD) valve 197, the safety switch 198, the clutch switch 200 and the oil pressure gage 202 are combined into a transmission wiring harness 7~ and terminate in a ~ransmission wiring harness connector 204.
Referring now to Fig. 3b, the transmission wiring harness connector 204 is similar to the engine wiring harness connector 12~, and it also contains an upper part 20Ç, a lower part 208 which engage each other in a labyrinth seal to protect against dust and water spray and can be snapped Z~ O
together over a detent and are provided with a wiring access opening that is formed generally by two cylindrical half shells 210, 212 and a bayonet ring 214. The upper part 206 accommodates a connector unit 216 whose location corresponds to the connector unit 74 of the cab wiring harness connector 20 and whose total of forty pin contacts, projecting upward, can be inserted into the corresponding sleeve contacts of the connector unit 74. The pin contacts of the connector unit 216 are connected to the electric lines of the transmission wiring harness 78.
The assembly of the transmission wiring harness connector 204 is similar to that of the engine wiring harness connector 126 in that initially the connector unit 216 is inserted into the upper part 206 and connected electrically with the lines of the transmission wiring harness 78, then the upper part 206 is snapped into the lower part 208 and the bayonet ring 214 is applied.
The pre-assembled transmission wiring harness connector 204 can be attached to the cab wiring harness connector 20 in such a way that the upper side of the upper part 206 of the transmission wiring harness connector 204 overlaps the portion of the underside of the lower part 48 of the cab wiring harness connector 20 that is not occupied by the engine wiring harness connector 126 and the contacts of the connector units 74 and 216 are inserted into each other. It is secured by a bolt 218, a washer 220 and retaining ring 222 in the same manner as the attachment of the engine wiring harness connector 126 by the bolt 164. Both bolts 164 and 218 may be configured identically. The bolt 218 is threaded into a nut 167 retained in the upper part 46 of the cab wiring harness connector 20. The junction between the cab wiring harness connector 20 and the transmission wiring harness connector 204 is sealed by a seal ring 224.
While the present invention has been described in con~unction with a specific embodiment, it is understood that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing 2l~ 0 description. Accordingly, this invention is intended to embrace all such alternatives, modifications and variations which fall within the spirit and scope of the appended claims.

Under the floor plate 15 of the cab 14 between the side spars 1~, 18 of the right step of the tractor, a cab wiring harness connector 20 is attached in an easily accessible location. The cab wiring harness connector 20 is the termination of a cab wiring harness 22 through which various electrical devices, operating and instrumentation units in the vehicle cab 14, such as fuse and relay boxes 24, instrument panel components 2~, differential lock switches 28 and power lift controls 30 are connected electrically with the poles of the cab wiring harness connector 20. A grounding cable 32 connects the floor plate 15 of the cab 14 with the engine bloc~ 34, which, for its part, is connected to the negative pole of the vehicle battery o (not shown). Studs 36, 38, 40, 42, 44, projecting downward, are weided to the floor plate 15 of the cab 14 and are used to attach the cab wiring harness connector 20 and the grounding cable 32.
The cab wiring harness connector 20 shown in Fig. lb includes a generally flat, shell-shaped upper part 46 and a flat, shell-shaped lower part 48. The upper part 46 has a surrounding edge 50 which projects downward. As best seen in Fig. 5, the edge 50 is provided with a downward opening groove 52 which receives the upward-projecting edge 54 of the lower part 48 when the connector 20 is assembled. The upper edge 54 is provided with detent projections 56 that engage corresponding recesses 58 in the edge 50 of the upper part 46 when the lower part 48 is attached. The junction between the upper part 46 and the lower part 48 forms a labyrinth seal which prevents the entry of water spray and dirt into the interior of the connector 20.
The upper part 46 includes a half cylindrical tube portion 60 which mates with a half cylindrical tube portion 62 formed in the lower part 48 to form a wiring opening. Grocves 64, 66, are formed within the wiring opening. One of the grooves receives an O-ring (not shown) which seals the connector housing against a flexible conduit (not shown), in which the electric wiring of the wiring harness 22 is carried.
The other groove receives a clamping ring (not shown) for the mechanical attachment of the flexible conduit. A bayonet ring 68 may be mounted on the assembled tube portions 60, 62 to retain the upper part 46 and the lower part 48 together and to clamp the flexible conduit (not shown) therebetween.
As best seen in Fig. 4, the lower part 48 contains three multi~pole connector units 70, 72, 74, each of which contains several chambers that accommodate sleeve contacts. The contacts are crimped to the free ends of the electric lines of the cab wiring harness 22 and inserted into the chambers so as to engage a detent. Two connector units 70, 72 provide a conne~tion with the engine wiring harness 76 and together contain twenty-four slee~e contacts. The third connector unit o 74 provides the connection with the transmission wiring harness 78 and contains forty sleeve contacts.
A bolt 82 extends through an opening 80 which extends through the bottom region of the lower part 48. The bolt 82 together with a washer 84 and a nut 86 is used to secure electrically a wiring connector 88 within the connector 20 and to the cab main fuse 90 which is mounted below and on the outside of the connector 20. The wiring connector 88 is connected to the fuse and relay boxes 24. The cab main fuse 90 is preferably a 125 amp. ceramic fuse which protects the entire cab electrical system. A spacer bushing 92 is mounted between the cab main fuse 90 and the underside of the connector 20 and provides the necessary free space for the cab main fuse 90.
In order to assemble the cab wiring harness connector 20, the connector contacts of the cab wiring harness 22 are initially inserted into the chambers of the connector units 70, 72, 74 and the wiring connector 88 and the cab main fuse 90 is secured to the lower part 48 by the bolt 82. The cab wiring harness 22, enclosed in a flexible conduit, is inserted between the opening formed by half cylindrical tubes 60, 62.
A hexagonal nut 9~ is inserted into a hexagonal recess 96 in the inner surface of the lower part 48. Now the upper part 46 and the lower part 48 are snapped together. At the same time a tube-shaped projection 98 (see Fig. 5) within the upper part 46 covers the hexagonal nut 94 and prevents it from escaping from the hexagonal recess 96. An internal hexagonal recess 100 in the upper part 46 covers the hexagonal head of the bolt 82 and prevents the bolt 82 from being turned. As a result, the cab main fuse 90 can be removed and replaced without the need for opening the connector 20.
In order to secure the cab wiring harness connector 20 to ~he vehicle cab 14, it is raised from below to the floor plate 15 so that the studs 38, 40, 42, 44 extend through corresponding bores in the upper par~ 46 and the lower part 48. These are secured by washers 102 and nuts 104 tightened on the studs 38, 40, 42, 44. Now a grounding attachment pin ~c~
106, which is provided at its one end with an internal thread 107 and with a hexagonal shape at its other end, is inserted through an opening 109 in the cab wiring harness connector 20 and is fastened to the stud 40. A collar 108 of the grounding attachment pin 106 is in contact with the underside of the cab wiring harness connector 20 and forces it against the floor plate 15 of the vehicle cab 14.
The grounding attachment pin 106 thereby performs two functions. On the one hand, it fastens the cab wiring harness ~0 connector 20. On the other hand, it electrically grounds the vehicle cab 14 by its metallic connection with the floor plate 15.
Referring now to Figs. 2a and 2b, the lines of the electrical accessories of the engine 110, for example, the generator 112, the tachometer 114, the air pre-heater 116, the fuel pre-heater 118, the starter 120, the temperature sensor 122 and the oil pressure gage 124, are combined in an engine wiring harness 76 and terminate in an engine wiring harness connector 12 6.
The engine wiring harness connector 126 is configured similar to the cab wiring harness connector 20, and similarly contains an upper part 128 and a lower part 130, which engage each other in a labyrinth junction for protection against dust and water spray, snap into each other in a detent and are provided with a wiring penetration opening that consists essentially of two cylindrical half shells 132, 134 and a bayonet ring 136. The upper part 128 encloses two connector units 138, 140, that correspond in size to the connector units 70, 72 of the cab wiring harness connector 20 and whose tota~
of twenty-four pin contacts projecting upward can be inserted into the corresponding sleeve contacts of the connector units 70, 72. The pin contacts of the connector units 138, 140 are connected to the electric wires of the engine wiring harness 76.
In addition, two four-pole plug-in connectors 142, 144 are arranged in the upper part 12~, whose contacts on the underside of t~e plug~in connectors (that is, the interior of ~3~ 0 the engine wiring harness connector 126) are connected to wires of the engine wiring harness 76 and on whose outer side, Yisible in Fig. 2, relays 146 can be attached. The relays 146 are a 70 amp. starter relay and a 70 amp. relay for the intake air pre-heater arrangement.
On its upper, outer side, the engine wiring harness connector 126 supports an engine main fuse 150 that protects the entire engine and starter electrical system. This is an B0 amp. ceramic fuse. The engine main fuse 150 is attached to the engine wiring harness connector 126 in similar manner to the above described attachment of the cab main fuse 90 to the cab wiring harness connector 20. This attachment uses a bolt 152, whose hexagonal head engages a hexagonal recess 154 in the inner wall of the lower part 130 to prevent its rotation, a spacer bushing 156, a washer 158 and a nut 160. The bolt 152 is used to attach the engine main fuse 150 as well as to attach and connect electrically wiring connection 161 arranged within the engine wiring harness connector 126. The wiring connection 161 is directly connected to the connection 163 of the starter 120 which, for its part, is connected to the positive pole of the vehicle battery.
The assembly of the engine wiring harness connector 126 is similar to that of the cab wiring harness connector 20 in that initially the connector units 138, 140 and plug-in connectors 142, 144 are inserted and connected electrically with the wires of the engine wiring harness 76. The hexagonal head of the bolt 152 is inserted into the hexagonal recess 154 and the spacer bushing 156 is applied. Then the positive pole attaching pin, described further below, and the two spacer 3~ bushings 184, 186 are assembled. Then the upper part 128 and the lower part 13~ are snapped together and the bayonet ring 136 is applied. The collar 187 of the positive pole attaching pin 182 secures this against escape from the engine wiring harness connector 126.
As best seen in Fig. 4, the engine wiring harness connector 126 can be attached to the cab wiring harness connector 20 in such a way that the upper side of the upper 2~it~0 part 128 of the engine wiring harness connector 126 overlaps a portion of the underside of the lower part 48 of the cab wiring harness connector 20 and the contact of the connector units 70 and 138 as well as 72 and 140 are inserted into each other. In order to provide the necessary free space for the relays, the lower part 48 of the cab wiring harness connector 20 contains a chamber 162 that opens downward. The attachment is made by a bolt 164 that is inserted from below into through holes 166, 168 in the engine wiring harness connector 126 and is threaded into a nut 167 which is retained in the upper part 46 of the cab wiring harness connector 20. To avoid any consequent deformation of the lower part 130 and the upper part 128 of the engine wiring harness connector 126 the through hole 166 extends within a ramp 170 that is part of the inner side of the lower part 130 and is supported on the inner side of the upper part 128. The bolt 164 is secured against loss by a washer 169 and a retaining ring 171 to the engine wiring harness connector 126. The interaction of the washer 169 and retaining ring 171 assists during disassembly of the wiring harness connector in releasing the relatively high contact forces that join the connector units 70, 138, 72, 140.
The lower part 48 of the cab wiring harness connector 20 is provided with an outer, surrounding groove which can accept a seal ring 172 which seals the joint between the cab wiring harness connector 20 and the engine wiring harness connector 126 against water spray. Furthermore, the engine wiring harness connector 126 contains through bores 174, 176, through which the grounding attachment pin 106 extends in the assembled condition.
Further, through bores 178, 180 in the engine wiring harness connector 126 accept the positive pole attaching pin 182 which can be threaded into the hexagonal nut 94 which is retained in the lower part 48 of the cab wiring harness connector 20. Two spacer bushings 184, 186 provide proper spacing and may be configured identical to the spacer bushings 92, 156. ~he positive pole attaching pin 182 si~ultaneously connects the free connections of the cab main fuse 90 and the o - engine main fuse 150 to each other. In addition, it is used, along with the bolt 164, to secure the engine wiring harness connector 126 to the cab wiring harness connector 20.
As a result, the positive pole attaching pin 182 connects the positive pole of the vehicle battery with the power supply wire of the vehicle cab 14, in that a connection is established between the vehicle batter~, the connection 163 of the starter 120, the wiring connection 161, the bolt 152 of the engine main fuse 150, the positive pole attaching pin 182, the cab main fuse 90, th~ bolt 82 and the wiring connection 88 which is connected to the power supply wire of the vehicle cab ~4.
The grounding attaching pin 106 and the positiv~ pole attaching pin 182 extend downward from the lower part 130 of the engine wirin~ harness connector 126 and are provided with a hexagonal shape in the projecting region. The projecting regions are protected at the side by a side wall 188. On th~
underside of the lower part 130 a pole cover door 1~0 is attached so as to pivot and to protect the two atta~ing pins 106, 182 from below. The pole cover door lg0 permits access to the attaching pins 106, 182, so that cables, not shown, of an external battery can be connected to the attaching pins 106, 182.
Referring now to Fig. 3a, the transmission 192 of the agricultural tractor is indicated in dotted lines. The lines of the electrical accessories of the transmission 192, for example, the differential locking valve 194, the ~orce measuring pins 196, the mechanical front wheel drive (MFWD) valve 197, the safety switch 198, the clutch switch 200 and the oil pressure gage 202 are combined into a transmission wiring harness 7~ and terminate in a ~ransmission wiring harness connector 204.
Referring now to Fig. 3b, the transmission wiring harness connector 204 is similar to the engine wiring harness connector 12~, and it also contains an upper part 20Ç, a lower part 208 which engage each other in a labyrinth seal to protect against dust and water spray and can be snapped Z~ O
together over a detent and are provided with a wiring access opening that is formed generally by two cylindrical half shells 210, 212 and a bayonet ring 214. The upper part 206 accommodates a connector unit 216 whose location corresponds to the connector unit 74 of the cab wiring harness connector 20 and whose total of forty pin contacts, projecting upward, can be inserted into the corresponding sleeve contacts of the connector unit 74. The pin contacts of the connector unit 216 are connected to the electric lines of the transmission wiring harness 78.
The assembly of the transmission wiring harness connector 204 is similar to that of the engine wiring harness connector 126 in that initially the connector unit 216 is inserted into the upper part 206 and connected electrically with the lines of the transmission wiring harness 78, then the upper part 206 is snapped into the lower part 208 and the bayonet ring 214 is applied.
The pre-assembled transmission wiring harness connector 204 can be attached to the cab wiring harness connector 20 in such a way that the upper side of the upper part 206 of the transmission wiring harness connector 204 overlaps the portion of the underside of the lower part 48 of the cab wiring harness connector 20 that is not occupied by the engine wiring harness connector 126 and the contacts of the connector units 74 and 216 are inserted into each other. It is secured by a bolt 218, a washer 220 and retaining ring 222 in the same manner as the attachment of the engine wiring harness connector 126 by the bolt 164. Both bolts 164 and 218 may be configured identically. The bolt 218 is threaded into a nut 167 retained in the upper part 46 of the cab wiring harness connector 20. The junction between the cab wiring harness connector 20 and the transmission wiring harness connector 204 is sealed by a seal ring 224.
While the present invention has been described in con~unction with a specific embodiment, it is understood that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing 2l~ 0 description. Accordingly, this invention is intended to embrace all such alternatives, modifications and variations which fall within the spirit and scope of the appended claims.
