Description

The present invention relates to a method for mounting an electrical line arrangement according to claim 1, a prefastening element according to claim 7, a connector according to claim 11 and a twisting machine according to claim 12.

It is known to twist electrical lines in pairs in order to reduce the sensitivity of the lines for irradiation of interference signals. It is also known to dispense with a twisting of the line in the region of a transition between twisted lines and a connector connected to the twisted lines. The untwisted area typically has a length of 2 cm to 3 cm. In this area noise can be radiated by the spanned between the lines surface very effective in the lines. In addition, the impedance of the lines is reduced in this area. Both result in limitations on a maximum data rate possible for data transmission over the lines.

In the prior art lines are twisted with twisting machines, in which a gripper engages the lines behind arranged at the line ends contacts. In order to be able to subsequently arrange the contacts of the lines in a plug connector, the last 2 cm to 3 cm of the lines remain untwisted in front of the contacts arranged at the line ends.

The DE 197 35 655 C2 describes a method for producing twisted, prefabricated lines and an apparatus for carrying out this method. The method provides to clamp two individual lines in a twisting device between two brackets. Subsequently, the lines are twisted by turning at least one holder.

The object of the present invention is to provide an improved method for mounting an electrical line arrangement. The object is achieved by a method having the features of claim 1. Another object of the present invention is to provide an apparatus for mounting an electrical conduit assembly. This object is achieved by a Vorsteckelement with the features of claim 7. Another object of the present invention is to provide an improved connector. This object is achieved by a connector having the features of claim 11. Another object of the present invention is to provide an improved twisting machine. This object is achieved by a twister with the features of claim 12. Preferred developments are specified in the dependent claims.

A method of assembling an electrical lead assembly according to the present invention includes steps of disposing a first contact on a longitudinal end of a first lead, disposing a second contact on a longitudinal end of a second lead, disposing the first contact and the second contact in a male member, and twisting the first line and the second line. Advantageously, the contacts are then arranged in the correct position in the Vorsteckelement after twisting the lines, so that they can be mounted directly and without further rotation in a connector. Since no twisting of the lines is necessary after the twisting of the lines in any case, the length of a region between the contacts and the beginning of the twist of the lines can be reduced to a minimum. This improves the electrical signal transmission properties of the electrical line arrangement mounted according to the method. In particular, the susceptibility of the electrical line arrangement for irradiation or emission of interference signals is reduced. In addition, an impedance decrease of the line order in the region between the twist and arranged at the line ends contacts smaller.

In a preferred embodiment of the method, the male member is gripped by a gripper to twist the first lead and the second lead. Advantageously, the gripper thus no longer engages the individual lines in this method but directly the Vorsteckelement, in which the connected to the line ends contacts are arranged. This achieves the shortest possible distance between the contacts arranged at the line ends and the beginning of the twist of the line arrangement.

In a particularly preferred embodiment of the method causes a force exerted by the gripper on the Vorsteckelement force exerted by the Vorsteckelement on an insulating jacket of the first line and / or an insulating jacket of the second line force. Advantageously, then takes place during the twisting of the lines only a small mechanical force input into the contacts. This advantageously reduces the risk of mechanical damage to the contacts.

In a preferred embodiment of the method, this comprises a further step of arranging the first contact and the second contact in a connector housing. Advantageously, the contacts are then pushed at the line ends directly from the Vorsteckelement in the connector housing. This simplifies the assembly of the lead arrangement, which allows to minimize the length of an untwisted area between the contacts located at the lead ends and the beginning of the twist of the leads.

In a particularly preferred embodiment of the method, the preform element is arranged together with the first contact and the second contact in the connector housing. Advantageously, the assembly of the contacts in the connector housing is then particularly simple and fast.

In an expedient embodiment of the method, the contacts are arranged by crimping on the lines. Advantageously, crimping makes it possible to produce mechanically robust and reliable electrical connections and can be automated at low cost.

A pre-insertion element according to the invention comprises a contact receiving area for receiving a first contact arranged at a longitudinal end of a first line and a second contact arranged at a longitudinal end of a second line. In this case, the Vorsteckelement is formed to be gripped by a gripper to twist the first line and the second line. Advantageously, the preforming element then enables the production of a twisted line arrangement in which a region between contacts arranged at the longitudinal ends of the twisted lines and a beginning of the twisting of the lines is very short. Advantageously, the contact elements are already arranged in the correct position after twisting in the Vorsteckelement, whereby subsequent assembly steps are simplified and can optionally be performed automatically.

In a preferred embodiment of the Vorsteckelements this has a clamping element which is designed such that a force exerted by the gripper on the Vorsteckelement causes a force exerted by the clamping element on an insulating jacket of the first line and / or an insulating jacket of the second line. Advantageously, this reduces the risk of damage to contacts connected to the lines.

In a further development of the prefastening element, this has a nose, which is arranged between a first line and a second line, when a first contact connected to the first line and a second line connected to the second contact are arranged in the contact receiving area. Advantageously, the nose then ensures compliance with a minimum length of an untwisted area between the contacts and the beginning of the twist of the lines.

In an additional development of the Vorsteckelements this has a displaceable slide, which is intended to push a arranged in the contact receiving area contact from the contact receiving area. Advantageously, then simplifies a displacement of the contacts connected to the lines from the Vorsteckelement in a connector housing of a connector.

An inventive connector comprises a connector housing having a receptacle for a Vorsteckelement of the aforementioned type. Advantageously, the Vorsteckelement can then be used together with all arranged in the Vorsteckelement contacts directly into the receptacle of the connector housing. This advantageously simplifies the assembly of the connector.

A twisting machine according to the invention for twisting electrical lines has a gripper, which is designed to grip a Vorsteckelement of the aforementioned type. Advantageously, this twisting machine permits the production of twisted electrical line arrangements in which the length of an untwisted area between contacts arranged at line ends and a start of a twist of the lines is minimal.
