Definitions

  • the invention relates to a multiple contact plug with an integrated short-circuit bridge element.
  • the invention also relates to a connector arrangement with such a multiple contact connector and a mating connector.
  • Electrical lines often have to be connected to one another in a wide variety of technical fields of application. For example, in vehicle construction, electrical lines coming from vehicle components must be connected to electrical lines from other vehicle components or, for example, from a control device. Several electrical lines are often combined to form a cable harness.
  • multiple contact plugs are often provided that can be plugged together with one or more mating connectors.
  • Such multiple contact connectors are sometimes referred to as harness connectors.
  • a plurality of contacts are provided in such a multiple contact plug, each of the contacts being connected to an electrical line as a rule.
  • the contacts are accommodated in a connector housing.
  • the contacts are arranged in such a way that when the connector housing is plugged together they are brought into electrical contact with a housing of the mating connector or housings of the mating connector with mating contacts arranged there.
  • a short-circuit bridge acts in such a way that when the plug connection is loosened, i.e. pulling the mating connector from the multiple contact plug, two of the contacts provided in the multiple contact plug are specifically short-circuited.
  • a short circuit that occurs can be detected, for example, by a controller monitoring the respective lines.
  • Such a functionality can be required, for example, for plug connections with the aid of which an airbag is to be electrically connected to other components, for example a control unit in a vehicle.
  • a circuit for triggering an airbag detonator is closed via the contacts that are specifically short-circuited when the plug connection is released, thereby preventing the airbag from being triggered accidentally.
  • a plug / mating connector arrangement is known in which, in the fully plugged together state, a short-circuit line on the top of the mating connector is contacted with a conductor of the connector. Contact elements without primary locking lances are arranged in the plug.
  • a plug / mating plug arrangement with a short-circuit element is known.
  • the short-circuit element is formed separately from contact elements without primary locking lances, which are arranged in the connector / mating connector arrangement.
  • the short-circuit element short-circuits two contact elements until the connector and mating connector are correctly locked together and the short-circuit element is then pressed down with a lever on the connector.
  • Embodiments of the present invention can advantageously enable a multiple contact plug or a connector arrangement in which targeted short circuits between contacts can be effected in a structurally simple manner when a plug connection is released.
  • a multiple contact plug according to claim 1 is proposed.
  • a connector arrangement which has a multiple contact plug according to an embodiment of the first aspect of the invention and a mating connector which can be plugged together with the multiple contact plug and which has one or more mating contacts which, in a plugged together state of the multiple contact plug with the Mating connectors come into electrical contact with a respective associated one of the contacts.
  • a short-circuit isolating element is formed on the mating connector, which is designed and arranged such that it is in the In the plugged-together state, the primary lance of at least one contact is displaced from the protruding into the spring-loaded position or in the direction of the spring-loaded position, thereby interrupting the contact between the primary lance and the contact surface of the short-circuit separating element.
  • short-circuit bridges are often formed with the aid of separate metal springs which, for example, press on the outside of a contact pin when the plug connection is open.
  • a geometry or gate provided on the mating connector is pushed between the short-circuit bridge and the surface of the contact pin and thereby interrupts the short circuit.
  • the short-circuit bridge is designed like a spring in this case, additional installation space is required within the multiple contact plug for the spring travel covered by it during compression. Such installation space is scarce, in particular when the miniaturization of components of a connector arrangement is provided.
  • a short-circuit bridge designed as a metal spring is usually a relatively complex bent stamped and bent part.
  • the short-circuit bridge element provided therein can be a very simple component, for example a simple sheet metal part, which does not need to be bent or only needs to be bent in a few steps and / or which requires minimal installation space.
  • the short-circuit bridge element in the multiple contact plug proposed here does not itself need to have an elastically resilient property. Instead, use should be made of the fact that the contacts to be received in the contact receiving chambers of the housing of the multiple contact plug are in many cases equipped with an elastically resilient element in the form of an elastically reversibly resilient primary lance. This primary lance can due to its outwardly resilient property to form an electrical Connection to the stationary and even not necessarily flexibly displaceable short-circuit bridge element can be used.
  • the primary lance which is also sometimes referred to as the primary locking lance, generally projects obliquely backwards in an unloaded state, i.e. contrary to an insertion direction along which the respective contact is to be inserted into a contact receiving chamber receiving it, from a, for example, box-shaped contact base body.
  • the primary lance can, however, be elastically reversibly deflected towards the contact base body.
  • the primary lance is generally used to lock the contact at least temporarily or provisionally within the contact receiving chamber, especially while the connector housing is being fitted with several contacts, before the contact is fixed in the contact receiving chamber at a later point in time, usually with the help of a secondary fuse.
  • the primary lance is initially deflected in order to then spring outwards again in a recess adjacent to the contact receiving chamber when it reaches a target position, in the direction of the outwardly protruding position and thereby be supported on an adjacent undercut and thus the contact in to be able to lock in the desired position.
  • the resilient property of the primary lance beyond its original task to detect a loosening of the multiple contact plug on the one hand and a mating plug on the other hand (i.e. the separation of the multiple contact plug and mating plug from each other) by creating a targeted short circuit .
  • the aforementioned short-circuit bridge element is provided in the multiple contact plug.
  • This short-circuit bridge element has at least two contact surfaces formed thereon.
  • the short-circuit bridge element is designed and arranged in such a way that each of the two contact surfaces protrudes into one of the contact receiving chambers in the connector housing.
  • the short-circuit bridge element with its contact surfaces is designed and arranged in such a way that each of the contact surfaces is arranged within the associated contact receiving chamber at a position at which the primary lance of the contact latched in this contact receiving chamber can, for example, press against the respective contact surface with a part of the primary lance protruding farthest from the contact base body.
  • the primary lance of the contact comes into mechanical contact and thus also into electrical connection with the contact surface of the short-circuit bridge element.
  • the short-circuit bridge element is designed such that this applies to at least two contacts latched in different contact receiving chambers, so that the two contacts are electrically connected to one another and thus short-circuited via their primary lances resting on the contact surfaces of the short-circuit bridge element.
  • the mentioned short circuit between at least two contacts in the multiple contact plug always occurs when the multiple contact plug is not connected to a corresponding mating connector. However, as soon as a correspondingly designed mating connector of a connector arrangement is plugged together with the multiple contact connector, the short circuit should be interrupted.
  • a, for example, link-like short-circuit isolating element is provided on the mating connector. This typically protrudes from an end face of the mating connector and is designed such that it engages in a suitable position in the multiple contact connector and thereby interrupts the short circuit.
  • the short-circuit isolating element can be pushed between the primary lance of the contact and the contact surface of the short-circuit bridge element, for example, and thereby the primary lance away from the contact surface, i.e. towards their spring-loaded position.
  • a signal can be generated that can be interpreted by a controller, or, alternatively, a circuit can be opened.
  • the airbag to be contacted by means of the multiple contact plug can be "armed" in this way.
  • the short-circuit bridge element is attached to the plug housing in a fixed position.
  • the short-circuit bridge element can be fixed firmly and immovably on the connector housing.
  • the short-circuit bridge element does not need to be a component which can be displaced relative to the connector housing, for example a spring-loaded component.
  • the short-circuit bridge element can be rigidly attached to the connector housing, for example, glued, screwed, riveted to the connector housing or cast into an injection-molded connector housing.
  • the jumper element can be fixed to the connector housing in such a way that its contact surfaces come to rest on the respective inner surfaces of the connector housing towards one of the contact receiving chambers, preferably rigid and immovable, and can be contacted there by the outwardly resilient primary lances of contacts received.
  • the short-circuit bridge element is in one piece.
  • the short-circuit bridge element can be provided as a simple, as simple as possible component, which is not composed of several parts but is designed as a single component.
  • the short-circuit bridge element can be designed as a sheet metal part suitably stamped in the form.
  • the short-circuit bridge element can preferably be flat, i.e. does not necessarily need to be bent into a suitable shape.
  • the short-circuit bridge element can be a one-piece sheet metal component, of which subregions are each arranged as one of the contact surfaces in one of the contact receiving chambers.
  • the contact surfaces can, for example, protrude into the contact receiving chambers from one side.
  • the contact surfaces connected to one another by the short-circuit bridge element can be located in adjacent contact receiving chambers.
  • the contact receiving chambers can, however, also not be arranged adjacent but further away from one another, in which case the short-circuit bridge element should be designed with a suitable geometry in order to electrically connect the contact surfaces received in the remote contact receiving chambers to one another.
  • the short-circuit bridge element can also be designed to be more complex.
  • two or more contact surfaces can be formed on separate components, for example sheet metal, and the components can be electrically connected to one another by means of any electrically conductive construction, which can be one-part or multi-part.
  • the contact receiving chamber has an undercut which the primary lance engages behind in its protruding position in order to lock the contact in the contact receiving chamber, the respective contact surface of the short-circuit bridge element in a region of the contact receiving chamber adjacent to the undercut, preferably downstream of the undercut in the insertion direction , is arranged.
  • the contact surfaces of the short-circuit bridge element in the respective contact receiving chambers in such a way that they are located at or near the undercut on which the primary lance should be supported in its protruding position in order to make contact in the respective contact receiving chamber lock into place.
  • downstream is used here only to describe a relative arrangement relationship with reference to the direction of insertion. It is not to be understood as an electric current. This also applies analogously to the term “upstream”.
  • the short-circuit bridge element covers a surface of the undercut at least in some areas.
  • the short-circuit bridge element which is usually made of mechanically resistant metal, can thereby mechanically reinforce the surface of the undercut and Protect the connector housing, which is usually made of plastic, in this area, for example, against damage by the primary lance.
  • the contact surfaces of the short-circuit bridge element have a coating.
  • the coating can e.g. be designed as a metal layer.
  • the coating is particularly preferably designed as a noble metal layer.
  • a noble metal layer for example a thin gold layer covering the contact area, can help to reduce a contact resistance between the contact area and a primary lance lying thereon. Furthermore, corrosion on the contact surface can be avoided.

  • the coating can be made of a material having good electrical conductivity, e.g. Carbon nanotubes or carbon, be formed.
  • the contact surfaces of the short-circuit bridge element are positioned in the contact receiving chambers such that the primary lance of a contact in its protruding position only contacts the respective contact surface when the contact is positioned within the contact receiving chamber in a predetermined manner.
  • the short-circuit bridge element with its contact surfaces can be specially designed and arranged in such a way that the contact surfaces are not arranged arbitrarily in the respective contact receiving chambers, but rather in positions specially provided for this purpose. These positions can be selected such that one of the contact surfaces is only reached and contacted by the primary lance of the contact when the contact is in a desired position within the contact receiving chamber.
  • the occurrence of a short circuit caused by the primary lance resting on the contact surface for example when fitting a multiple contact plug, can be interpreted as an indication that the contact has been correctly received in the contact receiving chamber and locked therein.
  • a cable is attached to the contact base in an electrically conductive manner and the contact base is connected to the primary lance in an electrically conductive manner.
  • a crimping area can be provided on the contact base body, to which a stripped end of the cable can be crimped.
  • the contact base body itself can be formed from an electrically conductive material, in particular from metal, for example in the form of a stamped and / or bent metal sheet.
  • the primary lance can be electrically connected to the contact base body or even formed in one piece with it. In this way, the cable is in electrical connection with the primary lance and short circuits caused by the primary lance can be detected via the cable.

  • the mating contact receptacle can be integrated into the contact base body. It can be designed, for example, with contact blades that can be touched by the counter contact. Since the mating contact receptacle is electrically connected to the primary lance, possibly even in one piece with it in the form of a common bent stamped and bent part, short circuits caused by the primary lance can also be detected on the mating contact.
