Definitions
- the invention relates to a cable connector with an inner connector body and a metallic shield housing.
- the connector body which accommodates a large number of contact parts, is encased in a sheet metal housing in order to improve the shielding effect, particularly in the case of high-frequency lines.
- the sheet metal housing has a circumferential collar which bears against a corresponding circumferential step-shaped shoulder of an inner wall of the screen housing.
- the individual wires of the connected cable are exposed and brought up to the individual contact parts. Electromagnetic fields develop on the exposed cables and contact parts.
- the invention has for its object to increase the electromagnetic tightness of the cable connector.
- the sealing strip creates a multitude of evenly distributed connections between the sheet metal housing and the shield housing, which improves the shielding effect of the arrangement.
- the outer edge of the collar is usually designed as a cut edge that has good dimensional accuracy and cleanliness.
- the sealing strip When installing the cable connector, the sealing strip is first inserted with the spring tongues into the shield housing up to the shoulder. Then the connector body is inserted.
- the spring tongues can be deflected by bending to the extent that they are braced between the collar and the inner wall of the shield housing. This is possible, for example, in that the spring tongues are alternately bent out in the opposite direction. Due to the arrangement of the sealing strip on the circumference of the plug body, the relative position of the parts relative to one another remains independent of whether a sealing strip is used or whether its use is dispensed with if the shielding effect is less stringent.
- the spring tongues are twisted about their longitudinal axis and change the direction of torsion from tongue to tongue.
- they are contacted both with the collar and the inner wall of the shield housing, which results in a correspondingly high number of contact points with a corresponding density.
- the points of contact are on the edges of the spring tongues, which are pressed into the surfaces of the collar or the shield housing. This results in reliable contact even with contamination or with the appearance of oxide layers.
- an electrical cable 1 with a multiplicity of individual wires 2 is inserted into a shield housing 3 and connected to contact parts 4 of a plug body 5. This is enclosed by a sheet metal housing 6, which has a circumferential collar 7 in its central region.
- the shield housing for example made of die-cast aluminum, is provided on its inner wall with a step-shaped shoulder 8, on which the collar 7 rests.
- An electromagnetic sealing strip 9 made of contact spring material is bent in a frame shape around the sheet metal housing 6 along the collar. It has a plurality of spring tongues 10 arranged in a comb-like manner, which extend perpendicular to the collar 7 and shoulder 8. The distance between the collar 7 and the inner wall of the shield housing 3 is so large that the spring tongues 10 are clamped between the contact strips.
- the spring tongues 10 are rotated about their longitudinal axis so that they form sharp-edged elevations on both sides, which are pressed into the surfaces of the collar 7 and the screen housing 3.
- the direction of rotation changes from tongue to tongue, whereby the resulting frictional forces compensate each other when the tongues are pressed together.
