Description
- The invention relates to a contact element for connecting electrical conductors, comprising connection means for electrically connecting the contact element to a conductor of a cable as well as a connection plate for connecting the contact element to a contact element of a further cable, wherein the connection plate has at least one locking element and at least one locking hole and wherein the at least one locking element is formed for engaging in a locking hole of the contact element of the further cable.
- Contact elements, often called cable lug, are used in the automotive industry for electrically connecting one or several conductors to a ground connection bolt. These several conductors are generally bundled together to a wire harness. The ground connection bolt and the car body, to which the ground connection bolt is connected, may also be called conductors. The processes during the manufacture of a wire harness or its transportation or its assembly to the ground connection bolt are hardly standardised and, therefore, prone to error and time consuming, especially then, when each cable lug of each individual conductor of a cable has to be individually connected to the ground connection bolt. Furthermore, the danger exists, that the wires get entangled or that an entanglement of the cables is produced.
- To solve this problem,
DE 10 2005 061 221 A1 describes a contact element, in which the connection plate forms at least one locking element and at least one locking hole, wherein the at least one locking element is formed for engaging the at least one locking hole of a further contact element. A locking between the two contact elements is to be ensured by means of one locking projection on a free end of the locking element. Thus, all cable lugs, which are to be connected to the ground connection bolt, can be pre-assembled to a unit. - The object of the present invention is to provide a contact element, which engagement in a further contact element ensures a secure connection during the assembly processes.
- The object is met by a contact element for connecting electrical conductors, comprising connection means for electrically connecting the contact element to a conductor of a cable as well as a connection plate for connecting the contact element to a contact element of a further cable, wherein the connection plate has at least one locking element and at least one locking hole and wherein the at least one locking element is formed for engaging in a locking hole of the contact element of the further cable, and wherein, furthermore, the at least one locking element has two locking projections, which are effective in opposed directions, for locking with the contact element of the further cable.
- The advantage of this arrangement is, that by means of the several locking projections, a secure locking of the first contact element in a further contact element is ensured. Thus, an axial as well as a radial fixation of two or more contact elements relative to each other is ensured during the transportation of the wire harness and before connecting the contact elements to a ground connection bolt. The contact elements are already pre-positioned and are secured relative to each other by means of this radial and axial fixation, so that the possibility of an undesirable wire entanglement is at least drastically reduced, if not even prevented. All contact elements connected to each other and which represent a type of a packet, can be pushed onto the ground connection bolt at the same time. This also contributes to a reduction of the process duration. These advantages are still increased, when, preferably, the locking projections are arranged at a specific minimal distance to each other.
- In a specific arrangement, it is preferred, that the locking projections are aligned facing away from each other, i.e. are effective. Generally, however, they can also face each and be effective. Preferably, the locking projections are aligned, when seen in circumferential direction, around a hole in the connection plate, facing away from each other.
- In a further embodiment the at least one locking element and the at least one locking hole are arranged on a concentrical circumference around a central hole in the connection plate. By means of the arrangement on a concentrical circumference, it is ensured, that two contact elements can be fixed to each other by means of the at least one locking element and the at least one locking hole, to be able to be pushed onto the ground connection bolt at an angle off-set to each other.
- In a further specific embodiment, several locking elements and several locking holes are provided on the concentrical circumference around the hole. Thus, a good fixation of the at least two contact elements relative to each other can be ensured. Preferably, the locking elements as well as the locking holes are, respectively, arranged diametrically opposite in pairs. More locking holes than locking elements can be provided, so that the contact elements can be positioned and fixed in several angular positions relative to each other.
- In a more concrete embodiment, the at least one locking element has two locking arms, which project from a plane of the connection plate. Thus, the necessary elasticity of the locking element is ensured. Preferably, the locking arms are made integrally from the connection plate by means of stamping and transforming. This structure can be manufactured in a simple manner.
- The locking arms can be formed such, that, respectively, one of the locking projections is arranged at the free end of the locking arms.
- When a first connection plate is coupled to a second connection plate, the connection elements of the first connection plate are passed through the locking holes of the second connection plate and project from the locking holes from the side of the second connection plate, facing away from the first connection plate. When now a third connection plate is to be coupled to the second connection plate, a space has to be provided on the third connection plate for the locking elements of the first connection plate, so that these are not again detached from their engagement. For this it can be provided, that the locking holes widen at least in the area, in which the locking elements engage, towards the side of the connection plate, which is facing away from the locking elements. Thus, the locking elements of the first connection plate can project through the locking holes of the second connection plate, engage behind these and enter the widened side of the locking holes of the third connection plate. Furthermore, the object is solved by a connection arrangement with at least two contact elements of the above described type, wherein the at least two contact elements are connected to each other, such that, respectively, a locking element of a first of the at least two contact elements is locked in a locking hole of a second of the at least two contact elements.
- In this case, it can be provided, that the locking projections of each locking element on the side of the second contact element facing way from the first of the two contact elements, engage behind the respective locking hole.
- In the following, a preferred embodiment is described by using the figures. It shows
- Figure 1
- a contact element according to the invention in a perspective view,
- Figure 2
- two contact elements locked to each other in a perspective view,
- Figure 3
- a connection arrangement with eight contact elements according to the invention,
- Figure 4
- a longitudinal sectional view through the connection arrangement of
Fig. 3 parallel to a longitudinal axis of the connection arrangement and - Figure 5
- an alternative embodiment of a contact element according to the invention.
- In the following,
Figures 1 to 4 will initially described together. - The
contact element 1 consists of aflat connection plate 3 with a central throughhole 8, which represents a central opening and by means of which thecontact element 1 can be plugged onto a ground connection bolt 11, shown inFig. 3 . Connection means 2 extend in a radial direction from theconnection plate 3 in form of a crimping connection, which serves in the present invention for contacting aconnection sleeve 12, in which opening 13 a not shown end of an electric conductor of a cable, which insulation is removed at an end, can be accommodated. Alternatively, the connection means 2 can also be formed in any other form, e.g. as an insulation displacement contact, a screwed contact or a soldered connection. - In this case, the
outer circumference 9 of theconnection plate 3 is formed octagonal. Other forms are also possible. Between theouter circumference 9 and the central throughhole 8, twolocking elements 4, 4' and sixlocking holes 6 are arranged on a concentrically enlarged circumference around the central throughhole 8 or around their geometrical centre. The twolocking elements 4, 4' are arranged diametrically to each other. Furthermore, thelocking holes 6 are arranged in pairs diametrically to each other. On the respective circumferential portions between thelocking elements 4, 4', threelocking holes 6 are arranged. - Each
locking element 4, 4' is formed by two lockingarms 5, 5', which can be manufactured by stamping and transforming from theconnection plate 3 and can project to one side vertically or nearly vertically from the plane of the connection plate. As the lockingarms 5, 5' or thelocking elements 4, 4' were produced from theconnection plate 3, material holes are produced radially within thelocking elements 4, 4'. - At their free ends, i.e. facing away from the bending area towards the
connection plate 3, the lockingarms 5, 5' have, respectively, locking projections 7, 7' in form ofprojections 16 facing parallel to theconnection plate 3. The locking projections 7, 7' can simply be formed by means of stamping and transforming. The distance of theprojection 16 to the upper face of theconnection plate 3 is, preferably, a bit larger than the material thickness of theconnection plate 3. The locking projections 7, 7' of alocking element 4, which consists of two lockingarms 5, 5', are aligned facing away from each other. This means, that the locking projections 7, 7' of onelocking arm 5, 5' are aligned, when seen in circumferential direction around the central throughhole 8 in theconnection plate 3, facing away from each other. "Aligned facing away from each other" means, that they enclose an obtuse angle between each other, i.e. that the directions, in which the locking projections 7, 7' extend, enclose a right angle or a larger angle. - As a further embodiment, but not shown, a locking element can also have three locking arms, respectively with one locking projection. In a top view onto the locking arms, these are arranged approximately 120 º off-set to each other, i.e. the directions, in which the locking projections extend, enclose an angle of approximately 120º. Thus, the locking projections are aligned facing away from each other.
- As a further embodiment, but not shown, a locking element can also have four locking arms, respectively, with one locking projection. In a top view onto the locking arms, neighbouring locking arms are arranged offset to each other by 90º concerning the directions, in which the locking projections extend. Thus, the locking projections of the locking arms, which are arranged off-set to each other by 180º, are aligned facing away from each other.
- In
Fig. 2 two identically formedcontact elements 1, 1', locked to each other, are shown, which form aconnection arrangement 10. The upper contact element 1' is locked relative to thelower contact element 1 such, that the connection means 2 are arranged at an angle to each other. In the present case, the angle off-set is 45º, because of two lockingelements 4, 4' and six lockingholes 6 which are being uniformly distributed about the circumference. It is visible, that the lockingarms 5, 5' of thelower contact element 1 project upwards through the corresponding locking holes 6 of the upper contact element 1'. When pushing the lockingarms 5, 5' through the locking holes 6, the lockingarms 5, 5' slide along angular sliding-slants of the locking projections 7, 7' through the locking holes 6, whereby the two lockingarms 5, 5' of alocking element 4 are elastically deformed towards each other, so that they are prebiased. As soon as the locking projections 7, 7' have reached the upper face of theconnection plate 3, the lockingarms 5, 5' of alocking element 4 snap because of the pre-biasing, again away from each other and the locking projections 7, 7 lock the twocontact elements 1, 1' relative to each other. Thus, thelower contact element 1 is locked, respectively, via alocking arm 5 by the locking projection 7, i.e. via theprojection 16 of thelocking arm 5 facing parallel to the plane of theconnection plate 3, relative to theconnection plate 3, i.e. relative to the upper face of theconnection plate 3, of the upper contact element 1'. - If now a further contact element, formed identically to the first two contact elements, is connected, this can be put onto the upper of the two contact elements 1', wherein this, for example, is again off-set by 45º to the upper of the two first contact elements 1'. Thus, the locking elements of the upper contact element 1' can engage in the locking holes of the further contact element. To prevent, that the locking connection between the two
first contact elements 1, 1' is not again detached by means of plugging-on the further contact element, the locking holes 6 are formed such, that they are formed enlarged in the direction towards therespective locking arms 5, 5', by which they are penetrated for locking. At least in the areas, in which the lockingarms 5, 5' engage behind the locking holes 6, i.e. in the shown embodiment, the locking holes 6, are formed enlarged relative to their extension in circumferential direction. On the narrower side of alocking hole 6, thus, this serves for engaging behind the lockingarms 5, 5'. On the wider side of thelocking hole 6, the lockingarms 5, 5' or the locking projections 7, 7' of acontact element 1, 1' can enter, which is locked to a directly neighbouringcontact element 1, 1'. The configuration of the locking holes 6 in a longitudinal sectional view is visible inFig. 4 . -
Fig. 3 shows aconnection arrangement 10 consisting of eightcontact elements 1, 1' after the plugging onto a ground connection bolt 11. By means of anut 15, thecontact elements 1, 1' are secured on the ground connection bolt 11. By means of thelocking elements 4, 4' and the locking holes 6, distributed evenly about the circumference, thecontact elements 1, 1' form a star-like arrangement. - The advantage of this locking is, that by means of the several locking projections 7, 7', a secure locking of the
first contact element 1 to a further contact element 1' is ensured. Thus, an axial as well as a radial fixing of two ormore contact elements 1, 1' to each other during the transportation of the wire harness or before the connection of thecontact elements 1, 1' to the ground connection bolt 11 is ensured. -
Fig. 5 shows an alternative embodiment of acontact element 1, wherein the lockingarms 5, 5' extend not freely radially outwards, but extend radially inwards forming a hole. For the rest, thecontact element 1 corresponds to that ofFig. 1 , wherein corresponding features are provided with the same reference numeral. -
