Definitions

  • the invention relates to a contact socket holder for electrical Connectors, where the contact sockets, in longitudinal receiving chambers an insulating body which can be locked within a plug housing are recorded and secured against axial displacement, the Contact sockets in the mutually parallel receiving chambers of the insulating body over with one between their socket area and their connection area Interacting base part designed for single conductors, diagonally to the socket axis aligned holding fingers or holding lugs against axial displacement are secured and the receiving area of the contact sockets Length sections of the receiving chambers of the insulating body at least towards the free end of it a light which exceeds the bushing diameter Have width.
  • Such a contact socket holder for electrical connectors is known from DE-OS 34 08 860.
  • an insulator body which can be fixed in a plug housing consists of two mutually complementary insulated body halves with mutually cursing receiving chambers for contact sockets, one of which is equipped with holding hubs which can be deformed radially to the contact sockets inserted into their receiving chambers and the other of which has radial extensions which hold the holding hubs of the receiving chambers.
  • the holding hubs have an unloaded state, ie before the insertion of the contact socket in the area of its free end a deviating from the circular shape, in particular quadrangular cross-sectional shape and are deformed by the insertion of the contact socket, whereby the holding hubs provided on the contact sockets are held together reach behind and thereby secure the contact socket against pulling backwards. Securing the contact socket against pulling out to the front is achieved when the insulating body is assembled by the system whose retaining collars on the radially directed extensions of the receiving chambers.
  • the contact socket is assigned a special retaining clip, which on the one hand is positively engaged with the contact socket and on the other hand via a Ring radially cranked spring clip narrowing the receiving chamber for engages behind the contact socket, whereby the contact socket initially in the pull-out direction secured in the insulating body or in the receiving chamber.
  • the retaining clip is equipped with a ring of spring fingers, via which is supported on a shoulder of the narrowing of the receiving chamber and thus supports the contact socket in the insertion direction against the insulating body.
  • the invention is therefore based on the object of a contact socket holder Design for electrical connectors specified in the beginning to improve that the contact sockets even while avoiding additional parts on the one hand within the receiving chambers of the insulating body receiving them are floating radially movable, but on the other hand with each separation of the Plug connection always aligned in a position coaxial to the chamber axis become.
  • This object is essentially achieved in that everyone Contact socket one with a small distance to its free end in the associated Receiving chamber arranged and resiliently trained Centering device is assigned.
  • a resiliently designed centering device on the one hand ensures floating radial mobility the socket inside the receiving chamber so that when assembled a plug connection can align the socket with the pin to be inserted, which is particularly important for connectors with a large number of plug contacts is advantageous, but causes on the other hand after disconnecting the connector also an automatic reset of the contact socket in one to the axis of the receiving chamber coaxial position, so that permanent inclinations of contact sockets are excluded in the reception chambers.
  • An advantageous embodiment of a contact socket holder according to the invention provides that the centering devices each have at least two the socket, formed with the insulating body of the same material and centering fingers positioned obliquely against the bush axis. A exact alignment of the contact sockets is achieved in particular by that three centering fingers for the associated contact socket per receiving chamber are provided.
  • the contact sockets one that narrows over part of its length and becomes free End of expansive contour and the centering fingers in the Range of their smallest diameter to the contact sockets.
  • Such Design has the advantage that the overall size is not enlarged Receiving chamber the centering finger a relatively strong, against the Contact receptacles can have a directed inclination, which is a relative soft suspension results.
  • the arrangement or mutual alignment of the contact sockets and the Centering fingers should be chosen so that the slots of the bushing from the centering fingers are at least partially overlapped.
  • the contact sockets 1 are received in a manner known per se and not particularly shown in the drawing, in a lockable insulating body which is likewise not shown in detail and secured against axial displacement.
  • the insulating body consists of two insulating body halves 3 and 4 which are congruent in terms of their cross-sectional shape and are aligned with mutually aligned receiving chambers 2 for the contact socket 1.
  • the contact sockets 1 each comprise a socket area 8, a base part 9 and a connection area 10 designed as a crimp connection for individual conductors, the base part 9 forming the shoulder 6 assigned to the attack of a contact holding finger 7.
  • the receiving chambers 2 are designed as cylindrical cavities and have a larger clear width compared to the contact socket diameter.
  • the contact sockets 1 Approximately over the half 11 of the length of its socket region 8 facing its free end, the contact sockets 1 have a conically tapering contour profile 12, which merges again into a protruding contour profile 13 towards their free end.
  • each of the receiving chambers 2 three centering fingers 14, which are formed in one piece and in one piece with the insulating body part, are arranged, which are oriented obliquely to the axis of the receiving chamber 2 and act on the contact sockets 1 in each case in the vicinity of their free end.
  • the centering fingers 14 engage the contact sockets 1 in the transition region between the conically tapering contour profile 12 and the again protruding contour profile 13. From the illustration in FIG. 3, it can also be seen that with contact sockets 1 slotted over part of the length of their socket area 8, the mutual arrangement of contact socket 1 and receiving chamber 2 or centering fingers 14 is such that the slots 15 of the contact socket 1 each are at least partially overlapped by a centering finger.
