To connect the shielding of an electric cable to a metallic connector, an electrically non-conductive cable guide part that features a wall segment of an electrically conductive material that needs to be laterally opened sectionally is provided. In this case, the shielding of the electric cable lying in the interior is connected to a corresponding mating connector by means of the wall segment and an electrically conductive connector sleeve surrounding the connector.
The invention pertains to a contact element for connecting the shielding of an electric cable to a connector.
The braided shielding of an electric cable or conductor can be contacted with a connector housing to be shielded with a variety of known connectors.
In this case, it is disadvantageous that an additional component is required in most instances in order to realize the electric contacting, wherein this additional component is supplied separately, easily forgotten during the assembly or lost.
The invention is based on the objective of realizing the contacting for a connector in such a way that the user is able to easily connect the shielding to the connector, wherein the contact element is connected to the connector in a captive fashion.
For this purpose, a conventional cable guide part that is otherwise known as a “splicing ring” and arranged within a connector sleeve features a wall segment that can be laterally disengaged, wherein the cable guide part is made of an insulating material while the wall segment consists of an electrically conductive material and can be advantageously engaged with the cable guide part.
The wall segment is shaped about semicircularly in accordance with the sleeve-shaped cable guide part and provided with a toggle lever that can be inserted into the interior of the cable guide part and engages therein, but advantageously allows an outward tilting movement. In this case, it is also advantageous that the wall segment that can be disengaged forms a funnel-shaped passage for simplifying the insertion of an electric cable.
FIG. 1 an exploded perspective representation of a connector;
FIG. 4 a partially sectioned cable guide part with an engaged wall segment, and
FIG. 5 the partially sectioned cable guide part with the tilted wall segment.
FIG. 1 shows a connector 7 in the form of a partially exploded representation with an electric cable 6, a coupling ring 5 that is pushed on said cable, a sealing insert 4 and a cable guide part 1 that is also referred to as a splicing ring, as well as a plug contact insert 3, in which not-shown electric contacts are arranged.
A contact element realized in the form of a wall segment 2 is also assigned to the cable guide part 1, wherein said wall segment occupies a recessed semicircle 20A of the cable guide part and can be tilted radially outward about an acutely angled edge 29 within the angular range of the recessed section of the cable guide part.
A zone 28 with a wedge angle of 30° formed by the acutely angled edge 29 is required in order to open the wall segment, wherein the wall segment is rotatably supported by means of a toggle lever 24 inserted into the cable guide part 1.
FIG. 2 shows the connecting element 1 in the form of a perspective representation, in which part of the interior structure is visible.
The connecting element 1 as a whole has the shape of a round body and features a collar in the upper part, wherein one collar half 10 is formed by the connecting element 1 while the second collar half 20 is formed by the metallic wall segment 2.
In this case, the wall segment is shaped identical to the collar of the connecting element in the region of the collar 20 such that a circular shape is realized that features two locking grooves 11, 21, into which one respective snap-in projection 41 of the sealing insert 4 to be attached on the collar can be inserted.
The interior structure as a whole forms an about rectangular cable opening 12 with a few through-openings 13.
In this case, one individual electric conductor 61 needs to be respectively inserted into the two through-openings 13 provided within the cable opening 12, wherein the stripped cable shielding is inserted into the cable opening 12 and fixed with the aid of the two ribs 14, 22 as shown in FIG. 3, in which the wall segment is still tilted into its open position.
FIG. 4 shows a perspective representation of the cable guide part 1, in which the wall segment 2 is illustrated in the closed position, wherein the cable guide part is longitudinally sectioned about centrally such that the function of the toggle lever 24 can be elucidated.
When the close wall segment 2 is pulled or pressed radially outward as shown in FIG. 5, the toggle lever 24 situated in the rectangular opening 16 is tilted about the acutely angled edge 29 within the free space 19 in the cable guide part 1.
During this process, the snap-edge 26 on the toggle lever jumps over the snap-in edge 18 in the rectangular opening 16, wherein the wall segment 2 is freely movable in any position between 0° and 30°, but still held in the cable guide part.
The electric cable 6 can be easily installed in this opened state of the wall segment 2.
During the assembly of the electric cable and the connector, the coupling ring 5 and subsequently the sealing insert 4 are pushed on the cable end of the electric cable 6. The wires of the individual electric conductors 61 and part of the shielding 62 are then exposed.
The wall segment 2 is then closed and the sealing insert 4 is joined with the cable guide part 1, wherein one of the oppositely arranged connecting notches respectively engages into the locking groove 11, 21 such that the cable guide part and the sealing insert form one unit.
