The invention relates to a connector with an insulating block. the continuous recesses aulwc-.st. into which a contour element connected to an electrical conductor can be inserted from one end and is detachable in the recess through a flexible element which is integrally attached to the block. wi) ^l > ei s: ch each Ricgd / urge from the Blovkvcue her in F.inMecknchlung of the Kon; ak! elemenli's extends into the recess and at the free end tire is formed as an axial and radial stop Ricge! na-, e, which : n the jerk / ugsbahn of a Gcgenansc'hla ^ esdjs contact element rat ^ t.

A connector of this type is from the DF-GM Ol 4J8 known. The bottom wall of the continuous recess of the Isolierstoffblockcs is flat Attachment for the underside of the Koniaktelcmcnlcs educated. The top wall is in the insertion direction and the distance from the insertion opening is incorrect set down on the bottom wall to form a sloping ceiling shoulder, to be continued

this sloping ceiling shoulder protrudes into the interior of the

Recess the latch tongue at its free end has a stepped locking nose that has an in Insertion direction axially facing stop and a radial direction from above on the top of the Kor.taktelementes forms cross stop. The bolt tongue is as a whole as an essentially formed straight arm, the attachment point on the top wall of the recess is flexible, wherein due to the resilient properties of the arm of the bolt tongue, the contact element against the bottom wall the recess is pressed. By forming a recess on the top of the contact element this has a recess approximately in the middle of its length. into the locking nose without touching it can intervene. At the front end of the recess, the contact element forms a contact stop. the with the axial and radial stop dt 'Kiegel.ise in eint; Ostei.kier position of the K.> ntaktclen.ciiti-s /us.im menvurM. liei 1'msi.hieben des Koni.ikielcmet.ics can Dodge the latch until the Koiuakieicmciu its fully inserted position in the recess reached, in dcr "diC Riegeinase in the locking position for Counter stop reached. If on the Kontak: element from the outside, z. B. via the electrical conductor. Retraction forces be exercised, prevents the bolt tongue together with the locking nose, the contact element is loosened from the block of insulating material. The The locking effect is greater when the retraction forces increase, because due to the arrangement of the arm of the bolt tongue around its flexible section the connection point with the top wall of the recess can bend inward, whereby the The contact element is pressed against the wall of the bocien The recess increases in this connector the entire locking force that secures the contact element against RuA / ugv krafie must be applied over the cross-section of the bendable section with which the locking tongue on the top wall of the recess attached, transferred and recorded. The insulating material block and the Riefelzun ^ ,; must therefore from made of a material that is sufficiently resistant to abrasion. This will increase the elasticity of the Riegel / unge restricted, whereby the Riegel / un.tt the insertion movement of the corr.akt element in de Opposite recess a relatively large resistance.

This task is solved by the Korrbit'ati'T. the characteristics:

When the contact element is fully inserted into the associated recess, but in the axial direction is not burdened. exists between the contact element and the bolt tongue a radial play. In this case, the bolt tongue is not pretensioned the contact element. At the same time, this means that when the contact element is inserted into the recess the locking tongue of the insertion movement of the contact element only has a low resistance opposed. This means that when the contact element is inserted in dt? Recess the friction between the two parts only slightly, so that even if the contact element is frequently exchanged, the locking tonguec including locking nose is subject to little or no wear. If, on the other hand, on that Contact element axial forces against the fin plug movement attack, the inclined guide surface takes care of the locking nose for that in cooperation between this guide surface and the countermeasure hit the locking nose is pulled radially inwards, the point of attack of the counter-stop on the locking nose over the back of this locking nose migrates radially outward until this migration by contacting the counter-stop also on the radial stop of the locking nose is put to an end. In the course of this movement, the point of attack comes between the counter-stop and the axial and radial stop of the locking nose to that of the Contact element facing away from the end of the back of the locking nose. This ensures that the now from the counter stop on the bolt tongue transferred jerk / pull forces allow an elastic deflection of the locking nose only in such a way that that this Riegelzungc in the area between their Attachment area to the top wall of the recess of the insulating block and the locking nose radially inwards This bends inwardly radial Bending of the bolt tongue. when the lock is loaded between the bolt tongue and the Contact element occurs is through a stop surface of the contact element set a limit, so that the locking tongue when loaded by the stop surface Defined deformation assumes and largely maintains this. This deformation is included such that the axial jerk / ugskraften by the radial Formation of the liiegei / un ^ e of this immediately as down on the U'-den wall of the recess deigned '.'. · radial compressive forces are exceeded. These d. Pressure creases increase the friction of the contact elemcnk-s on the Bedenwand As the bolt tongue at this training as a whole exists through corresponding deformation which itück / ugskrafic absorbs no risk of certain areas of the bolt tongue being exposed to excessive shearing forces. Therefore there is also greater freedom of choice! of Materials for the Isonstoffblock and also for go the Ricgel / unpe. which are thus made of more elastic material can exist.

The deformation of the bolt tongue radially inwards under the action of the retraction forces can also occur sharp increase in withdrawal forces to a defor- $ 3 exploitation of the element of contact at one point be, at which the contact element is connected to the electrical conductor in order to in this way the To secure connection between cem electrical conductor and the contact element in addition. For this purpose * is preferably the connection point between electrical conductor and contact element in the area d '* r Stop surface, and the contact element wetst in the area opposite the stop surface radial distance to the wall of the recess. which allows this deflection of the contact element.

The invention is explained in more detail below with reference to schematic drawings of an exemplary embodiment explained. It shows

When inserting the contact element into the Recess 14 of Isoliersioffblockes 12 needs the Latch clamps 32 only move slightly radially outwards, to ensure that the contact element is fully inserted. In the inserted position of the Kontaktclemenii-s 30 and in the unloaded state according to F 1 g. 3 J5 only criticizes the guide surface 58 in the jerk / ugs biihn di-% CiiTiMiiinM-hlagcs 5h. during the radial and the .ivi.ile stop 62, 64 radially .iiiUrüber this Riuk / iijTsbahn lnyrn.

If according to F-1 g. 4 a slight move against the -so Sick-in on the electrical conductor 38 is exercised, the Gtgenanschlag 56 transmits this Tensile force on the guide surface 58th whereby the Lock tongue 32 radially inward into the position according to F 1 g. 4 is pulled, with during this movement the counter-stop 56 slides radially outward on the guide surface 58 over the back of the locking lug 52, until it rests against the radial stop 62 and the axial stop 64 succeeded .. Since these stops on the from the contact element 30 facing away from the end of the back of the locking nose 52, it is ensured that the Riegdnase 32 under the effect of the jerk forces can only bend inward with its arm section 50. This deflection is caused by the deepening of the material 74 and the resulting increased flexibility of the Ricgel / ungo. Is the jerk force first only gennj. '. this is how the Menmendc · 42 des Koniiiktelementes from the floor wall 24 to / ur Attachment to the ceiling wall 26. like this F i g. 4 shows. If the backward force is increased, it also increases the endeavor of the arm section 50, radially inward to bulge out. However, the Kontaktelcment 30 forms Area of its connection point 40 with the electrical conductor 38 on the top of the Koniaktelementes lying stop surface against which the locking tongue 1111 area of its arm section 50 can create so that the flexible The bolt tongue remains limited .ind the retraction force over the arm section 50 into one of the \ rK <.- hljgfläche on the Kontaktclemeni 30 «acting radial pressure force is converted with which the Kontaktclcmeni now against the body wall 24 of the A'jsnchnving 14 printed wrj. like d.es Γι g. 5 shows.

Jerk / ue ^ forces primarily as Deformation forces absorbed by the rule, so the already extended film section 48 of the Ricgeizunge is relieved to a considerable extent.

As the F i g. Figures 3 and 5 show the joint 40 between contact element 30 and electrical Conductor 38 from the bottom wall 24 in the area of the contact element's AnsehlagPaehc normally one? n radial distance. This makes it possible. that when the retraction forces increase, the contact element 30 is under the pressure of the middle region 76 of the Armabichnittes 50 of the locking tongue 32 auvbiept downwards. This establishes the connection between the electrical conductor 38 and the Kontaktclcmeni 30 with increasing retraction force increases, so that the prisoner is banished. that the conductor 38 from the Konuktcletnent lost.

When comparing the F1 g. i to b it becomes clear that the bolt tongue is relatively flexible and can absorb a large part of the retraction force through internal deformation, so that a shear load on the bolt tongue remains in casting. The material of the insulating material block therefore needs to be selected less from the point of view of the shear strength. Since the bolt tongue according to FIG. 3 has a radial play compared to the contact element when the contact element is inserted but relieved, the wear on the locking tongue that occurs when the contact element is inserted and removed is very low, so that when selecting the material for the insulating block, the wear resistance of the material is only negligible · ¹ need to be taken into account.
