Definitions

  • the invention relates to a plug-in system with an electrical connector and a socket for non-positive connection of the electrical connector to the socket while contacting a plug of the socket with a socket of the electrical connector.
  • Such plug-in systems for producing a plug-in connection and in particular locking the plug-in connection are available in a plurality of variants, wherein, for example, the lock can be formed as a tab which engages over a corresponding latching lug. See eg US-A-6,491,542 ,
  • the basic idea of the present invention is to attach an at least partially resilient secondary locking means to a locking tab of an electrical connector, wherein a displacement of the secondary locking means into a locking position is enabled / released only by a locking lug of the mating connector or socket, if the mating connector is completely in electrical Plug connector is inserted.
  • the locking lug is preferably designed so that it simultaneously cares for a locking of the mating connector in the connector housing.
  • the secondary locking means prevents in its secondary locking position disengaging the Guide groove of the mating connector by limiting the spring movement of the locking tab of the connector housing.
  • an arm of the secondary locking means extends in the insertion direction S of the electrical connector and this is in particular directed in opposite directions or opposite to a guide rib on which the locking lug is formed.
  • the secondary locking means is particularly easy to lock when the arm is slidably guided in the connector housing, in particular on the locking tab.
  • the latching tab and / or the arm are resilient, the primary latch of the locking lug can be locked by snapping the locking lug in a corresponding shape of the locking tab.
  • a plug-in system in which the connector housing has at least one, in particular circumferential, guide groove for receiving the corresponding guide rib.
  • the socket housing is movable into a primary locking position in the connector housing when the secondary locking means is in a pre-assembly, in which the arm rests with its lying in the insertion direction S arm end to a locking tab stop.
  • the latching tab stop is formed by a recess which is arranged in the region of the lying in the insertion direction S of the latching tab end, the invention is further simplified structurally and the latching tab stop is formed simultaneously by the lying in the insertion direction S side wall of the recess.
  • a guide groove is provided in the connector housing and in a particular embodiment of the invention, the guide groove is configured so that the locking tab is disposed in the primary locking position between the arm and the guide rib.
  • the primary as well as the secondary locking is effected by these three components, wherein the effect of the primary locking against the direction of insertion takes place and only then can the effect of the secondary locking in the insertion direction.
  • the latching lug, the arm end and the recess in the primary locking position in the insertion direction S can be arranged at approximately the same height or on a plane and engage the latching nose and the arm end of opposite sides in the recess. Upon reaching the primary locking position, the latch snaps into the recess and at the same time presses the arm end of the arm out of the recess and releases it.
  • the insertion of the plug socket in the plug is greatly facilitated by the locking lug has a ramp for rebounding the locking tab.
  • the secondary locking means is movable into a pocket of the connector housing and a secondary locking position and thereby rebounding of the locking tab and thus a release of the locking lug from the recess is prevented.
  • the socket may be formed as a radial contact socket, which in particular has a plurality of longitudinal contact elements rotated in hyperbolic shape.
  • axial rods in the socket half are bent away allowing high current flow through the connection with minimal voltage drop.
  • the configuration with the hyperbolic punched notch guarantees a large overlap of the coaxially opposed surfaces. Since the resistance mainly depends on the contact, the normal force, the surface and the surface conditions, the best possible contact has been achieved by such a design of the connector.
  • the variety of surfaces of the flat grid guarantees the largest possible contact surface with the right plug.
  • the reduced contact pressure leads to less wear and a longer life.
  • the insertion force can also be adapted to the particular requirements by changing the twist applied to the inner grid.
  • the system inertia is minimized by the small housing and the fact that the contact has a spring force, whereby such connector endure extreme vibration and shock regardless of direction and intensity.
  • Fig. 1 shows above an electrical connector 10 with a secondary locking means 30 in a preassembled state.
  • the electrical connector 10 consists essentially of an L-shaped connector housing 12, on which a in Fig. 2 . 3 and 4 illustrated lid 12d can be attached, which closes the housing substantially.
  • the plug-in base 20 consists of a mushroom-shaped plug-type socket housing 22.
  • a cylindrical guide rib 24 extends substantially perpendicularly from a base plate 22p with coding ribs 24c formed thereon, on the one hand for preventing rotation and on the other hand for correct orientation of the plug-in socket 20 to the electrical plug-in connector 10 during mating to care.
  • a detent 23 is formed, which has a ramp 23r counter to the direction of insertion of the electrical connector 10, at the mating of the electrical connector 10 with the socket 20 in a Fig. 2 shown locking tab 13 slides along with its tapered end and finally in a primary locking position by the spring action of the resiliently configured locking tab 13, the locking lug 23 engages behind.
  • Fig. 2 . 3 and 4 the plug-in system is shown in the three essential states or positions in cross-section, wherein the cutting line (not shown) extends substantially through the center axis of the plug-in system.
  • a bushing 11 is designed as a radial contact bushing, which has a plurality of longitudinal contact elements rotated in hyperbolic form.
  • the bushing 11 is in conductive contact with the connector-side wiring harness. It is noteworthy that the connector shown here in reality has dimensions of a few millimeters and accordingly manufacturing tolerances play a much greater role. The more it depends on the structural design of the locking mechanisms to achieve a secure locking / locking of electrical connector 10 and socket 20.
  • a secondary locking means 30 is slidably formed, with a sliding movement through the structural design of the secondary locking means 30 and the connector housing 12 exclusively along the insertion direction S of the electrical connector 10 is possible.
  • an arm end 31 e is provided, which in the in Fig. 2 shown pre-assembly in the recess 15 of the locking tab 13 engages.
  • a displacement of the secondary locking means 30 is not possible in the pre-assembly due to the blocking by a locking tab stop 13a against the arm end 31e.
  • the attachment point can also be formed by any other embodiment of the secondary locking means 30, in which the relative movement of the secondary locking means 30 is blocked in the insertion direction S until the locking lug 23 has arrived in the primary locking position.
  • the stop does not necessarily take place at the end of the arm 31.
  • the secondary locking means 30 is easily accessible and operable from the outside by means of a handle 30g, which protrudes orthogonally to the insertion direction S from the secondary locking means 30. In the region of the arm end 31 e, the secondary locking means 30 dips into a corresponding pocket 16 of the connector housing 12.
  • the secondary locking position is in Fig. 4 shown. It is easy to see that by the design of the pocket 16, a rebound of the arm 31 and thus the locking tab 13 is prevented.
  • the bag 16 may also be formed by the plug base housing 22 in an alternative embodiment, as in Fig. 5 shown.
  • the key positions are the primary and Secondary locking effecting components (locking lug 23, locking tab 13, arm 31) shown.
  • the force required to release the secondary locking means can be adjusted by varying degrees of inclination (angle ⁇ ) of the arm end 31e relative to the arm 31.
  • angle ⁇ degrees of inclination
