Description

Technical area

The present invention relates to an aggregate connection for a vehicle.

State of the art

In modern motor vehicles, a variety of cables is needed to provide the individual consumers with electrical energy and to allow data exchange between components. Cable ducts are used in many places to bundle the cables and protect them against wear. The variety of cables are usually prefabricated to a cable harness. For laying a plurality of bundles of electrical conductors, the cable duct, which is often made of hard-elastic plastic, comprises U-shaped channels, which can be locally closed by cross straps. At the cable ends plug or cable lugs are arranged. When mounted in the vehicle plugs can be directly and easily connected to corresponding counterparts by a simple plug connection. The grounding of the wiring harness via a separate connection of a grounding cable with an electrically conductive component, such as the motor housing. Ground connections are usually provided in the vehicle as a bolt to which a cable lug can be connected. The cable lugs are crimped at the respective cable ends and additionally soldered in order to seal the cable end in a fluid-tight manner. Some OEMs are demanding extra moisture protection with a sock hose. The steps of crimping, soldering and attaching a sock tube are to be performed on different workstations. For crimping an extra tool and an additional test station is procured. The cable lug must be newly procured and developed for each cross section. The cable lug is therefore also validated for the application, whereby testing costs for the testing are again incurred. Thus, the placement of cable lugs on the wiring harness at the cable ends is time consuming and costly.

The current state of the art is thus found in the use of a cable lug for grounding on an existing mounting option on a conductive engine component by means of screw and threaded hole or alternatively by means of nut to threaded bolt. There is the challenge of crimping and soldering the cable lug, as well as the correct mounting of the cable lug at the ground point by the customer, both in harness manufacturing. In addition, further attachment points are required for the cable guides and shafts used.

Description of the invention

An object of the invention is therefore to provide a cost-effective connection of a cable to a contact pin such as a ground bolt in a vehicle using structurally simplest possible means. The connection to the contact pin should thus replace an existing in the prior art electrical ground connection.

The object is solved by the subject matters of the independent claims. Advantageous developments of the invention are specified in the dependent claims, the description and the accompanying figures.

An inventive aggregate connection for a vehicle comprises a contact plate and a housing open on one side. The housing is formed such that a plug can be inserted through an opening. The unilaterally open housing creates with the pins arranged therein a plug part or a socket as a counterpart to a plug part or plug, which is arranged on a wire harness or the like as a cable end. In this case, the combination of the plug part formed as part of the unit connection and a plug part formed on the cable or cable harness can be made fluid-tight and correspond to current standards and specifications for tightness. The contact plate has three sections: a contact tongue, a number of pins and a connecting portion connecting the contact tongue and the number of pins. The number of pins are arranged in the interior of the housing. The contact tongue protrudes out of the housing. The housing is fluid-tightly connected to the connecting portion. The housing thus fluid-tightly separates the contact tongue from the pins. The housing has a bottom and a collar. The bottom of the opposite side of the housing is open. The open side of the housing is also referred to as an opening. Depending on the design of the contact plate, this penetrates the housing in the region of the bottom or in the region of the collar. The floor may have a substantially rectangular, oval or round shape. The collar has a cylindrical shape whose contour is adapted to the shape or an outer contour of the bottom. Under a contact plate can be understood a cable lug, which is not crimped with one or more lines, but rather per line provides a pin, wherein a number of lines can be combined in one plug. In the connector then a per pin connected to a line contact element is provided, wherein the contact elements of the plug each contact a pin when the plug is inserted into the housing of the unit port.

In particular, the unit connection is an aggregate connection and / or ground connection for a motor-side cable set in a motor vehicle. The tightness requirement of the cable set with currently common plug connections can be taken into account.

Advantageously, in a wiring harness sealed plug can be provided, which are easily coupled with appropriate counterparts (sockets) during assembly. Such a connector assembly is also highly automated possible, whereby a consistent quality can be secured and at the same time can be produced inexpensively. Another advantage of the use of plugs in the area of a ground connection is that no screw connection is necessary, so that a simple tool-free assembly and disassembly is possible. Thus, further advantages can also be shown in the case of service.

The presented unit connection thus combines a cable lug with a plug connection, whereby a sealed connection, for example, of a number of ground cables to a ground connection is achieved.

The unit connection presented here creates an integration of a plug connection in a cable guide, also referred to as a cable duct, by means of a sheet metal part formed as a contact plate, which corresponds in function to the unit connection and represents the attachment of the cable guide.

By integrating the plug-in connection into the cable routing geometry, a standardized plug can be used instead of a standard cable lug, the assembly of which can be automated in harness production - which leads to cost savings and error reductions and also reduces the assembly effort at the OEM. Furthermore, the dismantling effort of the mass decreases in case of service, since only a plug contact must be removed and later re-infected, instead of loosening a screw and tighten again later with torque. Alternatively, the unit connection is fastened to the ground with a bolt or a screw connection, so that an electrical and mechanical connection is created.

The aggregate connection is advantageously formed against moisture (fluid-tight). Thus, the connection portion can be connected in a fluid-tight manner to the housing, in particular in accordance with IPX9K, as defined in ISO20653. Also, a connection between a connector plugged into the power connector and the power connector corresponding to IPX9K as defined in ISO20653 may be fluid-tightly connected to the housing. In this case, the tightness requirement of the cable set can be taken into account with currently common plug-in connections.

In a preferred embodiment, the contact tongue has an opening through which, for example, a ground bolt can be passed. Furthermore, in one embodiment, the contact tongue is designed as a blade contact. In this case, the contact tongue may be formed as a blade contact with a breakthrough. So a ground bolt can be passed through the opening, and then screwed the contact tongue with the ground bolt. Or in other words, after arranging the contact tongue on the ground bolt screwed onto this a screw to fix the contact tongue electrically and mechanically.

The housing is preferably made of a suitable plastic. In this case, the housing can be structurally designed such that the housing or individual parts of the housing can be produced with as little effort and preferably without the use of slides in injection molding tools. Thus, the housing may also be formed in two parts, when the two parts are fluid-tightly connected to each other.

Optionally, it is provided that the contact sheet is pretreated in the region of the connecting portion such that the fluid-tight connection to the housing is produced. Thus, the contact plate in the region of the connecting portion ribs or grooves and additionally or alternatively, the surface of the connecting portion for improved adhesion to be surface treated, such as sandblasted, plasma treated or other haftungsverlagernde measures have been performed.

Further, between the housing and the contact plate, a sealing element may be arranged, for example made of rubber or silicone. Such a sealing element may also be arranged only partially between the contact plate and the housing in a further variant in order to improve or ensure the fluid-tight connection.

Preferably, the pins of the contact sheet are aligned in the direction of the opening of the housing to be contacted simply and safely when inserting a corresponding plug.

In one embodiment, the contact tongue projects out of the bottom of the housing. In other words, the contact tongue projects in this embodiment on the opening of the housing opposite side out of the housing. Advantageously, in such an embodiment, the contact sheet can be easily and inexpensively manufactured by punching without additional bending.

Furthermore, a sealing lip can be arranged on an inner wall of the housing. The sealing lip may be configured to provide a fluid-tight connection between the housing and a plug contacting the pins. Furthermore, a first latching device can be provided on an inner wall of the housing, which is designed to engage with a second latching device on the plug contacting the pins in order to hold the plug in the unit connection.

The housing may have a fastening device on an outer side. Thus, the housing may have as fastening means a number of clips, snap-in hooks or apertures for screw fastening in order to fix the housing to an assembly of the vehicle such as the engine.

The housing may be integrally connected to a cable duct. Thus, fastening devices of the cable duct can fasten the unit connection to an assembly of the vehicle, such as the engine.

The aggregate connection can have a carrier section. Advantageously, the support portion is mechanically connected to the housing. In this case, the carrier portion may have an opening which is arranged such that the opening in the contact tongue of the contact plate is arranged overlapping thereto, so that a continuous breakthrough occurs. So a ground bolt or screw through both openings is feasible.

A manufacturing method of an aggregate terminal for a vehicle includes at least a step of providing and a step of arranging. In the step of providing an electrically conductive contact plate is provided. The contact plate has a contact tongue and a number of pins, wherein the contact tongue and the number of pins are connected via a connecting portion. In the step of arranging, an electrically insulating case is arranged to the contact plate. The housing has an opening. In this case, the arrangement provides that the contact tongue protrudes from the housing, the pins are arranged in the housing. Furthermore, the contact plate in the region of the connecting portion is fluid-tightly connected to the housing. Thus, the contact plate penetrates the housing as it were, and on one side of the penetrated wall the contact tongue projects out of the housing and on the other side the number of pins protrudes into the housing.

Preferably, the manufacturing method provides that the step of arranging is arranged as injection molding. Thus, in a preferred embodiment, the housing is molded in an injection molding process such that it is fluid-tightly connected to the connection section. It is optionally provided that a 2K method is used to produce the fluid-tight connection.

In the step of arranging, in a first substep, a preform can be fluid-tightly connected to the connecting portion, wherein the preform forms a bottom of the housing, and in a second partial step, a collar of the housing is formed. The collar is the tight interface between the unit connector and a connector dar. Here, the bottom of the housing and the collar of the housing can be made of the same plastic. Optionally, the floor can be made in a 2K process. Both the bottom and the collar can have ribs or grooves in a two-part production in order to improve the positive and / or material-locking connection of the two elements. In this case, provision may be made, in particular, for the temperature to be tempered after the injection molding in order to improve or enable a material-fit connection between the floor and the collar.

Furthermore, in the step of arranging during the injection molding of the collar additionally a cable duct and additionally or additionally a holding device for the aggregate connection or the cable connection comprising the aggregate connection can be injection-molded. Under a cable duct, a cable management can be understood.

The entire aggregate connection can also be assembled as a single assembly part in a subsequent assembly process in a form-fitting manner on the cable guide. In this case, the unit connection always serves to attach the cable harness (wiring harness) to the vehicle or engine. The holding device may be formed as a mounting element such as a dovetail. At the cable guide, a corresponding counterpart may be formed to connect the unit port with the cable guide and / or to lock. Alternatively, the holding device may have a passage or bore to be screwed to the cable guide, a ground terminal of the vehicle or an attachment point of the vehicle. In a further optional embodiment, the holding device may be integrally connected to the cable guide.
