is Such cross connectors are used to connect several busbars

i4 one or more terminals to the same electrical potential.

is The terminals are with their insulating terminal housing e.g. on a

The terminals are fixed to the mounting rail and lined up there.

17 housing is a busbar or several busbars for electrical

18 see contacting with one pole of the cross connector.

zo If it is a single-pole cross-connector, it is simply inserted into a

21 only terminal. In this terminal, e.g. in a so-called

22-level terminal block, several busbars are arranged one above the other

23 net. When plugged into such a terminal, the cross-connector

24 binder the busbars and thereby switches them to the same electrical

25 Potential.

27 A multi-pole cross-connector is used to insert the individual poles into the

28 busbars of several terminals. In this way, busbars are connected

29 different terminals are switched to the same electrical potential.

31 During the insertion process of the contact pins into the busbars

32, the contact pins pass through a correspondingly shaped slot of the

33 busbars. Each contact pin is assigned a contact spring. The spring

34 The force of the contact spring is normally perpendicular to the longitudinal axis or to the

35 Flat surface of the contact pin. The contact pin inserted into the rail slot

36 inserted contact pin is thus clamped into contact with the busbar.

&igr; A multi-pole cross-connector is known from DE 42 23 540 A1. There, the

2 Contact spring integral component of the contact pin. The spring-loaded con-

3 contact area of the contact pin requires a complex design and

4 accordingly a large manufacturing effort for the contact pins.

5 the contact pin takes into account both spring and electrical properties

6 must be considered is the material selection and dimensioning of the

7 contact pin is made even more difficult. In order for the contact area of the contact pin &bgr; to also function as a contact spring, the contact pin must be very

9 long.

11 From DE 42 01 219 C1 a multi-pole cross-connector is known which

12 above-mentioned disadvantages by using the integrated in the busbar

13 is acted upon by a separate contact spring. The u contact springs are, however, attached to the cross connector via additional components.

15 These components increase the manufacturing effort, the costs and also the

the space required by the cross-connector. Furthermore, the contact spring itself is space-

17 elaborately constructed.

19 Based on the disadvantages described, the invention has the task

20, the construction of a cross connector of the type described above

21 while retaining the advantages of separate contact springs.

22 times. This task is solved by the combination of features of the claim

23 solved

25 In the assembled state, the contact pin and the contact spring are directly

26 and are mechanically stable connected to each other.

27 through the entire cross connector in the assembled state is essentially in

28 can be aligned in a single plane. The very flat design of the cross connector

29 allows easy manual handling. The recording rooms of the

so terminals for the cross connector can be used because of its very simple and flat

31 geometric structure can also be manufactured more easily. In addition,

32, the clamps can be made smaller so that

33 the recording rooms and the busbars located therein against possible

34 are better protected against mechanical damage.

36 The material selection of the contact spring can only be based on mechanical

37 criteria for a good spring effect, since the electrical contact

&igr; contact pins. Depending on the purpose, the electrical con-

z timing of the terminal connector with the busbars can be improved,

3 The material of the contact spring also has good electrical conductivity

4, so that when the cross connector is plugged in, its effective electrical

5 Irish contact area with the busbars is enlarged.

7 According to claim 2, the contact pins form the comb teeth of a comb-like

β structure. They are aligned in the row direction of the contact pins

&bgr; metallic crossbar mechanically and electrically connected.

10 This contact comb uses its contact pins to switch the desired

11 Series direction of adjacent busbars of several terminals

12 to the same electrical potential.

14 The cross connector consists essentially of the contact comb, the contact

15 tactile springs and suitable fastening devices. These few components

16 facilitate warehousing and thus reduce storage and logistics costs &eegr; of the cross connector. The few components also promote the mechanical

18 genetic stability of the cross-connector. Furthermore, they contribute to a variety of

ie of wear-prone fasteners between individual components

µm to save.

22 Normally the contact comb alone already has sufficient mechanical

23 mechanical stability, since it is the sole current-carrying element and has an

24 sufficient cable cross-section must be available. Here, in the case of a

25 largely automated, machine-based production can be advantageous,

26 contact springs as individual parts to be attached directly to the contact comb. The

27 contact springs can then be made from a strip material with the cross-sectional dimensions

28 ing of the contact spring. The preformed strip material is

29 in a direction perpendicular to the length of the contact comb so fed to the assigned contact pin of the contact comb and fastened and cut off in one si operation. The special advantage of this production

32 method is that the contact springs are manufactured without waste and the

33 Blank of the cross connector can be stored in continuous format.

35 Claim 3 proposes a simple connection technique for the mechanically stable

36 bile fastening of the contact springs to the associated contact pins.

8 According to claim 5, the contact springs are part of a comb-like

9 picture. This spring comb is structurally simple to manufacture. The simple

10 Structure supports the easy assembly of the cross-connector

11 The spring comb carries the contact springs. The contact springs must

13 Attach the entire spring comb to the contact comb in a single step.

ie Usually, the contact comb and the spring comb are connected via their con-

17 tact pins or contact springs connecting brackets with each other mechanically

18. Since the brackets, i.e. the cross bar and the spring clip, extend in the row direction of the contact pins, the inherent stability of the cross connector is further improved along the row direction.

22 Claim 6 supports the technically simple manufacture and the self-stabilization

23 did the feather comb.

25 The contact comb and the spring comb according to claim 7 are arranged approximately in a

26 single plane. As raw material for such contact or Fe-

27 A variety of metal plate or sheet materials are available at low cost for contact combs. The processing of these raw materials into contact combs or spring combs takes place in very few work steps.

7 According to claim 10, the contact spring is designed to be particularly simple.

8. Designed as a leaf spring, the contact spring combines in a simple

10 Spring action of the spring comb.

12 A cross-connector according to claim 11 is suitable not only for the current

13 rails of terminals in a row, but also two or more &eegr; busbars of the same terminal to be connected to each other with the same potential. is The busbars are then arranged one above the other in the longitudinal direction of the contact pin in the ie terminal, e.g. in a multi-level terminal.

&eegr; For this purpose, the pole or poles of the cross connector are

The clamping contact points are spaced apart in the longitudinal direction and

20 are assigned to the respective busbars. It is conceivable to construct a

21 pole constructed in this way for a single-pole cross-connector.

22 It is also conceivable that in a multi-pole cross-connector,

23 individual or all poles are constructed according to claim 11. Such a

24 tiger cross connector can be used with a corresponding series of

25 tier terminal blocks and terminals with a single busbar

Set 26.

28 Claim 12 proposes a simple measure for electrically isolating the

29 areas of the vehicle normally used as handling areas

so cross connector during the insertion process or during the release of 31 the busbars.

33 The insulating jacket can be made of plastic, for example,

34 of the crossbar and the adjoining areas of the contact

&igr; The two insulating half-shells are then connected to one another in one piece, e.g. by welding, with the 2 cross connectors in between.

4 Claim 13 supports the easy handling of the cross connector by

5 an operator.

7 One or more casing slots according to claim 14 can be used for further

&bgr; Simplification of the handling of the cross connector as an attack surface for a

10 connectors can be removed from the busbars without any significant effort.

12 Furthermore, the sheath slot can be used as a fixing aid for a cable attached to the cross connector.

13 optical marking can be used. This prevents, for example, an operator from confusing individual cross connectors arranged in a row.

17 According to claim 15, each contact pin is assigned a jacket slot.

18 The casing slots are usually identically designed and arranged in a row direction ie at a constant distance from one another. This allows a tool

20 tool on the cross connector in its row direction always at the currently effective

21 softest point of attack. Furthermore, the casing slots allow a

22 simple optical marking of all contact pins of the cross connector. This

2 contact spring 13 assigned.

4 The contact spring 13 has an approximately rectangular cross-sectional shape and extends

5 in the longitudinal direction of the pin 5 approximately as far as the contact pin 3. The spring force
