Abstract
A device for grounding electrical components, particularly in a vehicle, comprises a bolt 1 and a connecting element 2. The bolt is attached to the body, for example by welding. The connecting element snap fits to the bolt - this makes assembly easier and gives a better connection than using a screw-threaded bolt and a nut. The connecting element 2 has numerous points at which electrical components or further connectors 6 can be connected.
Description
1 2342512 DEVICE FOR GROUNDING ELECTRICAL COMPONENTS The invention
concerns a device to ground electrical components, especially for vehicles, that comprises a grounded bolt attached (preferably permanently) to the body, and a connecting element that is releasably connected to the bolt and to which numerous electrical components can be connected.
In automobile manufacture, a threaded bolt welded to the vehicle body is usually used for connecting on-board electrical components to the frame potential. Ring cable connectors are placed on the threaded bolts, and they are fixed by a screw connection, e.g. a collared nut. The cable coming from the electrical component to be grounded is then connected with the ring cable connector. Grounding points at which such devices are located are either distributed in the vehicle at suitable sites or at a central base point, e.g. in the engine compartment.
In practice, it has been shown that such devices that use a screw connection are subject to large and undefinable voltage drops or changes in reference potential which can cause substantial problems, especially when modern bus systems are used. The use of CAN-BUS systems permits a maximum specific voltage drop in vehicles of 1.15 V that cannot be guaranteed by the systems used to date. In addition, screwing together the elements represents a complicated step in the installation process that can produce quality problems. High costs arise from this time- consuming and complicated step.
The invention is based on the problem of pi;esenting an easilyconstructed device where only low, limited voltage drops or shifts in reference potential arise.
This problem is solved with a device according to the invention according to the preamble [of claim 11 where the connector mechanically snaps onto the bolt, and at least one part of the lateral surface of the bolt forms an electrically-conductive connection to an assigned surface of the connector.
An advantage of the device according to the invention is that the snap-on connection without screwing is a simple method of installation, it saves time and costs, and prevents quality problems. No installation tools are necessary, and there is no radial load (torque) on the prior-art bolts. Since the majority of the lateral surface of the bolt represents a conductive connection with a corresponding area of the connector when the bolt and connector are locked together, there is less transition resistance in contrast to the state-ofthe-art connection, and the voltage drop is less and limited which allows e.g. the safe use of CAN-BUS systems. The device according to the invention can be used flexibly at different sites in the vehicle. A specific voltage drop or change in reference potential no longer depends on how the device was installed, i. e., the torque.
In a preferred embodiment, add-on modules are provided in addition to the connector that can be connected with each other along with the connector at the provided contact sites; an electrically conductive connection is formed between the add-on module and the bolt via the connector. The addon modules and the connector have connection sites for connecting electrical components. Alternately, just the add-on modules can have the conneqtion sites for electrical components, and the connector can have just contact sites for connecting the add-on modules but not direct connections for the electrical components.
The connection between the add-on module and connector is preferably releasable, e.g. a plug-on connection.
Such a modular system consisting of a connector and addon modules to be added as necessary allows a flexible solution when differing numbers of electrical components are to be connected to different grounding points. In particular, the number of unused connections to the grounding points can be reduced when there are few components to connect.
In addition, the overall number of grounding points in the vehicle can be reduced since the modular system according to the invention can provide a large number of connecting sites at a single grounding point.
For each add-on module to be added, the connector must have a contact site; hence the maximum number of add-on modules to be added is determined by the number of provided contact sites. Usually, a good balance is found between a high degree of flexibility and a moderate number of contacts sites on the connector with a device that has a maximum of four modules comprised of a connector and up to three add-on modules.
The components to be connected to the frame potential are preferably connected to the connector or an add-on module (connected to the connector) by a plug-in connection to the connector.
In addition to the standard required conneqtion sites, the connector and modules can have other connecting sites to connect other optional systems or services that are only used as special equipment.
A flexible solution can be easily attained for different cable crosssections, e.g. by placing tabs with different widths, especially 1.5 mm and 2.8 mm on the connector or modules.
Especially with bodies made of plastic or aluminum or hybrid bodies, all the utilized devices according to the invention connected to the respective bolt or connectoy are preferably via a cable to the negative terminal of the voltage source supplying the electrical components so that no current needs to flow via the body. This yields a particularly low voltage drop (ground return).
The connector and each add-on module are advantageously in their own housing. If in addition guide elements are provided on the housing and the guide elements of an addon module can interact with guide elements of a connector, the electrical connection between the add-on module and the connector can easily be made by pushing together the housings. When they are pushed together, a contact site of the connector electrically contacts the contact site of the relevant add-on module. To keep the housings from undesirably separating and breaking the contact, housing fasteners can be provided, e.g. on the connector to hold together the housing of the connector pushed together with the add-on housing. The plug-on force is such that the plug on process can be carried out manually in the assembly line of the vehicle manufacturer.
Other advantageous embodiments of the device according to the invention can be found in the subclaims.
The device according to the invention is primarily used to connect electrical components via cable sets to grounding points in automobiles. However, other uses are conceivable.
The invention will be further explained in the following using an exemplary embodiment with reference to drawings. Shown are:
Fig. 1: a perspective overview of the exemplary embodiment of the invention, Fig. 2: a perspective view of a bolt to be welded to the body of a vehicle according to the exemplary embodiment of the invention, Fig. 3: a perspective view of a connector according to the exemplary embodiment of the invention, Fig. 4: a perspective view of an add-on module according to the exemplary embodiment of the invention, Fig. 5: a perspective view of a connector with a housing, and Fig. 6: an exemplary distribution of the exemplary embodiment of the invention in an automobile.
Fig. I provides an overview of the portrayed exemplary embodiment of the device according to the invention that clarifies the assignment of the different parts to each other. The plastic elements belonging to the device were not shown in this view.
A bolt 1 is shown that is not connected to the other components of the device according to the invention, but it is welded to the body of a vehicle (not shown).
A connector 2 that is also shown has a connecting element 3 via which the connector 2 can lock with the bolt 1. The connector 2 also has several connection sites 4a, 4b for connecting cables (not shown) from components of the vehicle to be grounded. Likewise three contact sites 5 are also on the connector 2 to create an electrically conductive connection with an add-on element 6.
An add-on element 6 is connected to each of the contact sites 5. Each of the add-on elements 6 has other connections to connect cables. The add-on elements 6 are designed identically in this case to attain a particularly simple modular system. Depending on the requirements, add-on modules with different designs can be used.
The individual components in Fig. 1 will be described in greater detail in the following with reference to Fig. 2-4.
Fig. 2 shows a bolt 1 according to the exemplary embodiment of the invention. The bottom end of the bolt 1 has a welding site la to which the bolt 1 can be welded to the body of the vehicle to fix it and ground it. The bolt 1 is cylindrical in the middle lb. This area lb serves as a contact area for a high-current contact with the connector 2 from Fig. 1. At the top end of the bolt 1 7 - is a groove lc that serves to lock the associated element of the connector 2.
The connector 2 is displayed separately in Fig. 3. In the middle, there is an essentially hollow cylindrical element 3. The connector 2 and the hollow cylindrical element 3 are permanently attached. This element is used to attached the connector 2 to the bolt 1. The connector is attached by snapping on the connection element 3 using an embodiment (not shown) of the connecting element 3 assigned to the groove lc of the bolt 1. When snapped on, the inner surface of the hollow cylindrical connecting element 3 is tight against lateral surface of the bolt 1, especially its contact area lb. In this manner, a low-ohm transition is created from the connector 2 to the grounded bolt 1. Such a connection can be created very easily in the manufacturing process since it is a plug-on connection and not an involved screwed connection.
The connector 2 also has several connection options for electrical components of the vehicle to be grounded. Tabs 4a with different widths such as 1.5 mm and 2.8 mm are primarily suitable for such connections, as well as areas 4b that are provided for ultrasonic welding of cables.
Finally, there are three contact areas 5 on the connector 2 onto which add-on modules 6 can be correspondingly plugged.
Fig. 4 shows one of the add-on modules 6 from Fig. 1. Like the connector 2 from Fig. 1 and 3, the add-on module 6 has different connection sites for electrical components that are to be grounded. Tabs 6a and an area 6b are provided as connection sites for ultrasonic welding. Corresponding to one of the contact areas 5 of - 8 the connector 2, the add-on module 6 has a,-contact tongue 6c. The add-on module 6 is plugged onto this contact tongue 6c on one of the contact areas 5 of the connector 2 as shown in Fig. 1.
Fig. 5 shows a connector 2 from Fig. 1 or 3 with a housing 2a. The housing 2a provides access to the connection sites in the form of tabs 4a and an area for ultrasonic welding 4b for connecting electrical components, and for the contact areas 5 of the add-on modules 6. In addition, guide bars 2b can be seen by means of which the add-on modules 6 with a corresponding housing can be shoved together with the connector 2; an electrically conductive connection is created between the add-on module 6 and one of the contact areas 5 of the connector 2. The housing 2a is also provided with a housing fastener 2c that holds the connection of the shoved-together housings of the connector 2 and the addon module. This prevents the combined parts from unintentionally separating.
Fig. 6 shows a vehicle with a possible distribution of devices according to the invention in the vehicle with the exception of the engine compartment. Bolts 1 are connected to the body and provided with connectors 2 at grounding points M. The connector 2 is provided with zero to three add-on modules 6 as needed at the connections to the individual grounding points M. With the modular system that can provide a large number of connections at a single bolt 1, it is possible to have fewer grounding points M where devices are attached for grounding electrical components than is the case with prior art devices.
