Definitions

  • the invention relates to an electrical connector, having a connector housing, a locking device for locking the connector with a corresponding mating electrical connector and a locking element that can be displaced between a pre-locking position and a locking position, according to the preamble of claim 1.
  • the invention also relates to a security element for an electrical connector.
  • the invention also relates to an electrical plug connection, having an electrical plug connector and a mating electrical connector corresponding to the plug connector, according to the preamble of claim 14.
  • An electrical plug connector or an electrical mating connector can be a plug, a built-in plug, a socket, a coupling or an adapter.
  • the term "connector” or “mating connector” used in the context of the invention is representative of all variants.
  • connectors for the motor vehicle industry are subject to high demands in terms of their robustness and the safety of the connectors.
  • a plug-in connection must sometimes withstand high loads, for example mechanical loads, and remain closed in a defined manner. It must be ensured that the electrical connection is not disconnected unintentionally, for example while a vehicle is in operation.
  • the plug connectors must ensure problem-free transmission of electrical power, electrical signals and/or data even in contaminated, damp and/or chemically aggressive environments.
  • plug-in acknowledgment must also be provided for a fitter of the plug-in connection. This can be done, for example, by the mating connector only being able to be plugged into the connector if the connector has previously been installed correctly.
  • the aging of a plug connection can lead to a safety-critical problem.
  • electrical plug connectors in particular for the automotive sector, have security elements which prevent a plug connection from being unlocked unintentionally and thus prevent the mating connector from being separated from the plug connector.
  • the security elements are generally exposed to long-term mechanical and thermal stress, which causes their aging can still accelerate.
  • the fuse elements can eventually become brittle and break, which means that they can no longer fulfill their intended function.
  • the U.S. 2019/044278 A1 relates to a connection device comprising: a terminal, a housing that houses and holds the terminal and is engaged with a mating housing by being releasably locked by causing a locking portion to be locked to a locked portion shown in is provided to the mating housing when an engaged state with a mating connector is a fully engaged state; and a detection element mounted on the housing and disengaged in an engaging direction and a disengaging direction with respect to the housing between a main locking position when the engaged state is the fully engaged state and a lock release position when the engaged state is an engaged state in the fully engaged state, is relatively mobile.
  • the US 9,929,509 B1 relates to a connector assembly having a first connector with a primary locking lever pivotally attached to the first connector.
  • the second connector includes a primary striker that locks the first and second connectors together with the primary latch.
  • the assembly further includes a Connector Position Assurance (CPA) device slidably mounted to the first connector and a CPA lever defining a secondary latch.
  • CPA Connector Position Assurance
  • the secondary latch engages the side rib to prevent movement of the CPA device from an initial position to a final position until the first and second connectors are fully mated.
  • the WO 2010/032088 A1 and the US 6,491,542 B1 each also relates to an electrical connector with a CPA element and relates in particular to electrical connectors for use in motor vehicles.
  • the object of the present invention is to provide an electrical connector with an improved safety element, in order in particular to increase the ease of assembly and the service life of the connector.
  • the present invention is also based on the object of providing an improved security element for an electrical plug connector.
  • the object is achieved for the electrical connector with the features listed in claim 1. With regard to the electrical plug connection, the object is achieved by the features of claim 14.
  • An electrical connector having a connector housing, a locking device for locking the connector with a corresponding electrical mating connector, and a locking element that can be displaced between a pre-locking position and a locking position.
  • the locking element blocks the locking lock in the locking position to prevent unlocking of the mating connector.
  • the connector and the mating connector are preferably electrically and mechanically operatively connected for the intended use of power and/or signal transmission.
  • the locking device can preferably form a so-called primary latching of the plug connection with a corresponding latching element of the mating connector, for example a latching hook of the mating connector.
  • the securing element can ensure that the electrical plug connector and the electrical mating connector are held securely in their plugged-in state, since movement of the locking device for unlocking the mating connector is blocked by the securing element.
  • This principle is sometimes referred to as “housing locking” or “connector position assurance” (CPA).
  • the locking device can have a latching section for latching with the mating connector, in particular with a latching hook of the mating connector.
  • the latching section can preferably be arranged in the area of a front end of the locking device that faces the mating connector. For example, in the insertion direction of the mating connector, a recess can be provided in the locking device immediately behind the latching section, into which the latching hook of the mating connector can penetrate for locking with the connector. The latching section can thus be gripped from behind by the mating connector or by its latching hook.
  • the locking device can preferably be designed as a locking rocker.
  • the latching rocker can have the latching section for latching with the mating connector or with its latching element.
  • the latching rocker can have a recess behind the latching section in the region of a front end of the latching rocker that faces the mating connector. The latching hook of the mating connector can thus engage in the recess of the latching rocker and thus lock the connector.
  • the locking rocker can have an actuating section, in which case the locking rocker can be pivoted about an axis of rotation formed between the latching section and the actuating section by actuating the actuating section, for example by a user of the plug-in connection, in order to unlock the plug-in connection by "lifting" the latching section - at least if the securing element is not in its securing position.
  • the locking device can preferably be designed as a locking rocker of a FAKRA connector.
  • the connector housing forms a feed along which the securing element can be displaced from outside the connector housing in the direction of the longitudinal axis of the connector housing into the pre-locking position.
  • This “radial” insertion of the securing element in the direction of the longitudinal axis of the connector housing can advantageously reduce the size of the connector housing in the longitudinal direction.
  • the feed is preferably designed to move the securing element into the pre-locking position by means of a linear movement in the direction of the longitudinal axis of the connector housing. In principle, however, a curved movement can also be provided.
  • the securing element is positioned in the pre-locking position in the connector housing in such a way that the securing element is brought into a pre-securing position by plugging in the mating connector, in which the securing element is mechanically braced, with the connector housing forming a guide , along which the securing element can be displaced from the pre-securing position into the securing position and is thereby mechanically relaxed, preferably completely mechanically braced.
  • the securing element can - optionally after an intended release by a user - move from the pre-securing position into the securing position, while the securing element relaxes mechanically .
  • the mating connector has been removed, however, it can also be provided that the securing element—optionally after an intended release by a user—moves from the pre-securing position back into the pre-locking position, while the securing element relaxes mechanically.
  • the securing element starting from the pre-securing position, strives for either the securing position or the pre-locking position.
  • the pre-secured position can initially be a stable position, whereby the "automatic" movement of the securing element caused by elasticity or spring force into the secured position or into the pre-locking position can be triggered or controlled by intervention by the user of the plug connection.
  • the pre-fuse position can also be an unstable position, as a result of which the "automatic", elasticity or spring force-related movement of the fuse element into the safety position or back into the pre-locking position takes place immediately after the pre-fuse position has been reached - depending on whether the mating connector is in the connector is plugged in or not.
  • a “pre-latching position”, a “pre-securing position” or a “securing position” can mean a position (e.g. axially and/or radially with respect to the longitudinal axis of the connector housing) and/or an orientation (e.g. tilting) of the securing element .
  • the first variant of the invention can be implemented as an alternative or in addition to the second variant of the invention.
  • the two variants are related to each other in that they can increase the security of the plug connection while maintaining a simple assembly (each individually or in combination). All of the features, configurations and developments described below can advantageously relate to both variants of the invention.
  • the displacement path for the securing element ends in the securing position in which the securing element is positioned between a latching section of the locking device and an outer wall of the connector housing in order to block the locking device.
  • the securing element In the securing position, the securing element preferably does not protrude with its front end facing the mating connector beyond the latching section of the locking safeguard. In the securing position, the front end of the securing element can terminate, for example, in a coplanar manner with the outer housing of the connector, in which case the securing element can also be set back in the connector housing or can form a recess.
  • the displacement path of the securing element in the connector housing between the pre-locking position and the securing position is preferably limited, in particular the axial displacement path along the longitudinal axis of the connector housing.
  • the securing element can thus preferably no longer be pushed further, for example after the securing position has been reached.
  • the securing element is arranged in the pre-locking position in the connector housing in such a way that the securing element is completely unstressed mechanically.
  • the securing element is arranged in the securing position in the connector housing in such a way that the securing element is mechanically completely unstressed.
  • the securing element is particularly preferably completely mechanically relaxed in the securing position and in the pre-locking position.
  • the service life of the securing element can be significantly increased, since prolonged mechanical stress (when using the plugged-in connection or when storing the individual plug-in connector) can be avoided.
  • the securing element is preferably mechanically braced in the pre-securing position.
  • the feed is designed in the connector housing in such a way that the securing element can be displaced into the pre-locking position by a movement running essentially orthogonally to the longitudinal axis of the connector housing.
  • the securing element thus preferably performs a radial movement or a lateral movement in the direction of the longitudinal axis of the connector housing during insertion into the connector housing.
  • the movement can be straight or curved.
  • an axial directional component can also be provided.
  • the securing element can be displaced by a movement along a straight line in the direction of the longitudinal axis of the connector housing, with the straight line having a feed angle of 1° to 90°, preferably 10° to 90°, particularly preferably 20°, with the longitudinal axis to 90°, more preferably 45° to 90°, more preferably 70° to 90°, and even more preferably 80° to 90°.
  • the fuse element may have a front end portion and a rear end portion opposite to the front end portion along the longitudinal axis of the connector housing when the fuse element is inserted into the connector housing.
  • the securing element can have a securing area with which it is able to block the locking safeguard.
  • the displacement path for the securing element ends in the securing position in which the securing area of the securing element is positioned between the latching section of the locking device and the outer wall of the connector housing in order to block the locking device.
  • the securing area of the securing element in the securing position therefore preferably does not protrude beyond the latching section of the locking safeguard.
  • the securing area of the securing element can terminate coplanarly with the outer housing of the connector, for example, but the securing area of the securing element can also be set back in the connector housing or can form a recess.
  • the securing element has the securing area, a support area and a spring area located in between, the securing area on the front end section of the securing element facing the mating connector and the support area on the opposite side of the front end section along the longitudinal axis of the connector housing , Rear end portion of the fuse element is arranged when the fuse element is inserted into the connector housing.
  • the spring area can be designed to be deformable or at least partially elastic in order to introduce mechanical stress into the securing element.
  • the deformability or the elasticity of the spring area can be selected in such a way that the securing element can bend sufficiently reversibly for its intended use without undergoing (irreversible) plastic deformation.
  • the spring area can preferably be formed by one or more spring arms, which extend from the front end section or a middle section of the securing element in the direction of the rear end section.
  • the support area can preferably (but not exclusively) be formed directly on the free ends of the spring arm or spring arms, for example by means of laterally protruding lugs.
  • two spring arms can be provided to form the spring area, which run on opposite sides of the securing element.
  • three spring arms or more spring arms, four spring arms or even more spring arms can also be provided.
  • the securing element in a further development of the invention, provision can be made for the securing element to be positioned in the connector housing in the pre-locking position in such a way that the insertion of the mating connector results in a displacement of the securing area of the securing element running essentially orthogonally to the longitudinal axis, while the securing element is in contact with the support area supported on the connector housing, preferably such that the intermediate spring area is mechanically braced.
  • the mating connector can cause a lifting or pivoting movement of the securing element in its front end section, while the distance between the support area and the longitudinal axis of the connector housing remains (at least essentially) unchanged.
  • the optional (but preferred) bracing of the spring area during the displacement of the securing area can be achieved, for example, by bending the securing element in the connector housing instead of rotating the securing element.
  • rotation of the securing element can be mechanically prevented and, for this purpose, a central section between the front end section and the rear end section of the securing element can be held axially and/or radially in the connector housing while the mating connector moves the fuse element.
  • the pre-locking position preferably differs from the pre-locking position in the connector housing only by the alignment of the locking element and by the bracing of the spring area.

  • a "backup prevention function" can be realized as a result.
  • the securing element in the securing position blocks the locking safeguard with the securing area in a form-fitting manner.
