DETAILED DESCRIPTION

[0025] FIG. 1 illustrates the sectional front view of the plug connection 100 having a socket pin 10, which is designed as a mass connection, and having the contacting partner in the form of a lamella socket 20 in the relative position with respect to one another prior to the plugging process. The position of male the contact pin 10 flush and perpendicular to the contact socket 20 is the positioning prior to the plugging process, in other words the contact partners are (still) not in engagement. The assembly unit comprising at least the slider 110, the socket housing 120 and the socket contact 20, which is received therein, and the spring 101, is brought into the plugging position by way of the socket pin 10.

[0026] The spring 101 is designed as a helical spring, compression spring and accordingly pre-tensioned, with the result that the slider 110 is pushed in the illustrated position into an end position relative to the socket housing 120 and against the stop that is formed from at least one shoulder 112 and at least one protrusion 122.

[0027] The slider 110 is supported in this positioning situation in a non-positive locking manner with its at least one support hook 111 against the cone 11 and/or the chamfer 12 of the male contact pin 10, with the result that the assembly unit comprising at least the slider 110, the socket housing 120 and the socket contact 20, which is received therein, and the spring 101, is arranged in the defined position with respect to the socket pin 10. Likewise, the supporting arrangement of the at least one support hook 111 is relevant with regard to the flow of force for compressing the spring 101, since it functions as a counter bearing of the spring 101 with respect to the movement force and the relative movement travel of the housing 120.

[0028] The continuation of the electrical contacting arrangement to a voltage source, an electrical consumer or a mass connection, ground connection, can occur by way of a cover 130. For this purpose, the socket housing cover 130 is equipped with contacting means for the lamella contact socket 20 and said contact means comprise at least in sections the outer contour of the lamella contact socket 20.

[0029] On the male contact pin side, in other words on the plug side of the plug connection 100, all the latching and supporting geometries 11, 12 are integrated into the male contact pin 10 itself, there is no surrounding additional geometry in the form of a male contact pin housing or similar, in which these functions are accommodated. FIG. 1 illustrates a free-standing mass pin 10 that is welded for example to a vehicle body.

[0030] FIG. 2 comprises the sectional front view of the plug connection 100 having a socket pin 10, which is designed as a mass connection, and having the contacting partner in the form of a lamella socket 20 in an in part plugged situation. The plug connection 100 is plugged in part by virtue of the fact that the plugging travel of the socket pin 10 into the lamella contact sleeve 20 is (still) not fully performed up to its end position in the contact socket 20. It is preferred that the end position is realized after the maximum possible plugging travel and the latching, secondary-locking arrangement is preferably implemented in the end position.

[0031] The amount of the in part plugging travel, illustrated in FIG. 2, corresponds to the distance which the socket pin 10 is pushed into the lamella contact socket 20. The slider 110 is pushed with the plugging movement and against the spring force of the spring 101 relative to the housing 120 in an axial manner. The at least one latching hook 121 lies in this plugged situation with a hook incline 121′ against the chamfer 12 of the cone 11. The hook incline 121′ and the chamfer 12 are coordinated with one another with respect to their inclines in such a manner that the outward deflection of the latching hook 121 is supported during a further plugging travel in the direction of the end position of the socket pin 10 into the lamella contact socket 20. The angle of inclination of the hook incline 121′ is sufficiently small with regard to the axial line with the result that the inclined surface is reliably prevented from becoming jammed against the chamfer 12. Usually and depending upon the surface finish, smoothness of the surfaces that move relative to one another, an angle of inclination less than 45° is possible.

[0032] If the plugging procedure is interrupted, for example in the situation illustrated in FIG. 2, by virtue of the fact that the outer plugging force for overcoming further compression of the spring 101 is no longer exerted against its already realized spring pre-tensioning, the result is that the plug connection and the contacting situation is terminated. As a result of the stored spring force, realized pre-tensioning and by way of the force flow support of the at least one support hook 111 at the chamfer 12 of the cone 11, the spring 101 pushes the housing 120 having the lamella socket 20 in the axial direction out of the contacting position.

[0033] FIG. 3 illustrates the sectional front view of the plug connection 100 with the socket pin 10 and the contacting partner in the form of a lamella socket 20 in the plugged situation in the end position. In this case, the contact pin 10 is pushed into the contact socket 20 by the maximum possible insertion travel. The spring 101 is pushed in as far as to close to the block, the housing 120 is moved a maximum into the slider 110 and lies at the end face against the slider base.

[0034] The at least one support hook 111 of the slider 110 is located in an in part outward deflected situation which is brought about by means of the inner sleeve 123 of the housing 120 in dependence upon the insertion travel of the socket pin 10 into the lamella socket 20. The support hook 111 is included in the illustrated outward deflected situation (still) in the function of the counter bearing for the spring 101 and holds the slider 110 in the position in which, as far as geometrically possible, it receives the housing 120.

[0035] The latching function, in other words the secondary-locking of the plug connection 100, is realized in accordance with this exemplary embodiment in the end position and as a result brings about that the latching hook 121 engages, viewed in the plugging direction, behind the cone 11 against its conical surface 11′ and holds the housing 120 in a releasable non-positive locking manner.

[0036] FIG. 4 illustrates the sectional front view of the plug connection 100 having a socket pin 10 that is designed as a mass connection and having the contacting partner in the form of a lamella socket 20 in a plugged and latched, secondary-locked situation. With the outward deflection of the at least one support hook 111 out of its supporting position at and against the cone 11 and/or the chamfer 12 of the contact pin 10 and as a result thereof out of its counter bearing function, the slider 110 is pushed by means of the pre-tensioned spring 101 in an axial manner and relative to the housing 120, with the result that the part of the socket pin 10 which has hitherto still been exposed is covered by means of the housing. It is preferred that the slider end position is defined by means of a stop, the stop is illustrated on a vehicle body part. A stop is also possible on the housing 120 of the plug connection.

[0037] The spring residual pre-tensioning and the length relationship of the housing 120 and the slider 110 in the axial direction are coordinated with one another in such a manner that the tensioning of the plug contact system 100 is low in the secondary-locked end position.
