Definitions

  • the invention relates to a locking system for plug connectors for connecting and locking a plug with its plug partner, having a primary lock, formed from at least one bayonet ring with at least one control link, coupled with one
  • Connector plug and designed for functional interaction with at least one pin assigned to the control link on a connector mating connector.
  • Such high-voltage connectors are often implemented as circular connectors with one or more plug contact pins and, in addition to reliable, detachable and permanent contact, must in particular also protect against unwanted or through
  • bayonet or screw locks are often used as primary locks in circular connectors. These securing means are usually permanently attached to the respective plug connections and are supplemented by secondary locks to protect against unintentional disconnection. In the prior art, securing means are usually used as spring-like arrangements which engage with corresponding openings or catches and thereby cause two parts of a circular connector to be locked.
  • Rotary lock which, like a bayonet lock, is attached to the plug connections in such a way that the connector pair is fixed to a locking thread by means of a locking screw.
  • Locks of this type are problematic, in particular, when the aim is to prevent the lock from being released unintentionally or improperly and / or from pulling the plug connector under voltage. In the latter case, arcs can ignite, especially in the high-voltage range, which are problematic in terms of safety and can endanger life.
  • connector locks in particular screw locks, can loosen over time as a result of these mechanical vibrations and the connector is no longer reliably connected to the mating connector.
  • a plug of this plug connection comprises an inner subassembly, an outer sleeve which is mounted displaceably with respect to the inner subassembly and at least partially encloses the inner subassembly and first locking means for locking the plug with an associated plug connector part when the plug is plugged onto the plug connector part, the locking being effected by a Displacement of the outer sleeve with respect to the inner assembly can be solved.
  • Such connectors consisting of a plug and a connector part, are known as push-pull connectors. This name is derived from the function of such connectors. These can be closed by simply plugging the connector onto the connector part in one direction of insertion (“push”).
  • the connector part can be a socket or a second plug. When plugging on or by plugging on, locking means of the plug and the
  • Connector part locked together so that the connector is not by a train z. B. can be solved on a cable connected to the connector.
  • the outer sleeve of the plug is pulled against the direction of insertion (“pull”).
  • Pull direction of insertion
  • the locking means are unlocked.
  • the plug is released from the connector part.
  • an additional operation must be performed to lock or unlock.
  • Such a process would be, for example, the raising or lowering of a locking hook serving as a locking means or an additional rotational movement of the outer sleeve, such as. B. common with so-called bayonet connectors.
  • the disadvantage is that accidental loosening of the connector can occur due to the simple unlocking process by pulling on the outer sleeve.
  • Another disadvantage of the known plug-in connectors of this push-pull type is that any person who has access to the plug connector can release such a plug connector without any further aids. Accidental, arbitrary or unauthorized loosening cannot be prevented with the known connectors of the convenient push-pull type.
  • Locking element is provided, which is slidably mounted and can be brought into at least one stable locking position in which the displacement of the outer sleeve with respect to the inner assembly is blocked, and at least one stable release position in which the displacement of the outer sleeve is released with respect to the inner assembly is.
  • Connector part and socket part consisting of coupling halves for connecting and disconnecting multi-core electrical high-voltage and / or low-voltage lines, each coupling half consisting of a substantially cylindrical receiving electrical contact elements
  • Housing exists, both of which can be coupled by means of a coupling sleeve.
  • the coupling sleeve has a radially inwardly projecting nose for engagement in a locking groove which is formed on the housing end of one of the two coupling halves.
  • the locking groove consists of an in
  • Circumferential end portion in which an axially or obliquely
  • Lead-in section opens, with a torsion spring being arranged in the union sleeve, one end of which is in the union sleeve and the other end at the not with the
  • This three-part connector device is coupled or decoupled via a bayonet system.
  • the torsion spring has the effect of a closing spring, which in the
  • a connector coupling is presented, consisting of a first coupling half, which has at least one coupling housing and a contact carrier housed therein
  • Connecting element includes suitable area of the coupling housing.
  • the primary lock is optionally available as screw connections, for example by means of
  • Notch-shaped catches are assigned on the inner circumference of the sleeve forming the connecting element.
  • a secondary locking means is attached to one of the plug connectors in such a way that the primary locking means, preferably the locking ring, is in its
  • the secondary locking or the secondary locking means is designed as a spring pin arranged between the connector and the connector socket. A so-called pogopin can be used as a spring pin.
  • the Pogopin is constructed in such a way that the spring pin pin can resiliently dip into the spring pin body and when the spring pin pin is released it can return to its original position against a spring force of a spring arranged in the spring pin body.
  • the spring pin is arranged on the connector socket in such a way that it can plunge into a recess on the locking ring of the connector after locking the locking ring by engaging the spring pin pin in a recess on the locking ring and thus securing the locking ring against loosening.
  • the spring pin engages the corresponding secondary locking recess and fixes the primary lock, preferably a locking ring, in its intended position.
  • the arrangement of the spring pin relative to the connector partners is always chosen so that the spring pin movement takes place axially to the connector in an also axially aligned recess.
  • the invention solves the problem by means of a locking system for connectors, in particular for high-voltage connectors (DC connectors) with a primary lock formed from a bayonet lock and a functionally coupled secondary lock formed from at least one locking slide.
  • the primary locking takes place according to the invention by a two-stage bayonet lock which can be locked in the locking end position by the secondary locking against unintentional release.
  • the secondary locking is provided by at least one locking slide, which is either a functionally-integrative component of the bayonet ring or of the associated connector housing.
  • the at least one backdrop of the lock solution based on the bayonet principle offers an associated pin two latching positions, which are achieved by the Z-shaped extension.
  • a first and a second insertion depth of the corresponding Steek connector mating connector is assigned to the two locking positions.
  • the bayonet ring has a rotational degree of freedom that supports two end positions.
  • the bayonet ring is designed in such a way that it has at least two positions which can be achieved by a combination of axially linear displacement and rotary movement.
  • One of the end positions supports an unlocked state of the primary lock, the other end position supports the locked position. In the unlocked position (if the connector and mating connector can be separated) the associated pin can be moved through the link. In the locked position of the
  • the functionally coupled secondary locking can be activated so that the movement out of the locking position in the link groove is locked with the result that the
  • the secondary lock designed as a locking slide, can be moved into a position that prevents the pin from moving in the link by means of a stop and locks it in the locked position.
  • the rotative degree of freedom of the secondary lock designed as a locking slide, can be moved into a position that prevents the pin from moving in the link by means of a stop and locks it in the locked position.
  • Bayonet rings blocked so that the bayonet ring cannot be moved out of its locked position.
  • High-voltage connectors with primary and secondary locking not only reduce a number of the aforementioned disadvantages of the prior art, but also achieve further advantages: In the locked position, the shock and / or vibration resistance is increased. Independent rotation of the locking ring due to vibrations can be excluded, since the ring is formed from at least one by means of the secondary lock
  • Locking slide is held in locking position
  • Unauthorized loosening of the plug connection can be prevented by the optional design of the locking position, in that the secondary locking is only released by a tool;
