Definitions
- the present invention relates to a connector housing assembly and a connector housing having such a connector housing assembly.
- the housing of a high-load connector should not only have a defined electromagnetic shielding capability, but also a defined tightness. For example, it should meet the IP67 protection class in terms of waterproofness.
- an electrical intermediate connecting element for example a metal frame
- a metal frame is provided between a first housing body and a second housing body of the connector housing.
- the connector housing can thus meet the defined requirement for electromagnetic shielding, it is hardly possible to meet the requirement for watertightness in this way.
- a rubber sealing ring is provided between the first housing body and the second housing body, the area of which in the transverse direction, however, is generally larger than the corresponding area of the first housing body and the second housing body, which means that the end regions of the first housing body and of the second housing body are not in contact with one another, so that compliance with the requirement for electromagnetic shielding is hardly possible.
- a connector housing assembly comprising a housing body, the housing body having a housing body end region surrounding its opening and a sealing ring, a side surface of the housing body end region being in locking engagement with a side surface of the sealing ring .
- the outside of the housing body end region can be in latching engagement with the outside of the sealing ring.
- the inside of the housing body end region can be in locking engagement with the inside of the sealing ring.
- the housing body end area has a first recess, a second recess and a shoulder arranged between the first recess and the second recess.
- an end face of the housing body end region is designed in a step-shaped manner.
- the sealing ring has a main body, a first bulge arranged on one side of the upper region of the main body, a second bulge arranged on one side of the lower region of the main body and a sealing groove arranged between the first bulge and the second bulge, wherein an upper end of the main body is above the first bulge.
- the main body forms the first bulge and the second bulge in one piece with one another.
- first bulge can be in locking engagement with the first recess and the shoulder can be in locking engagement with the sealing groove.
- the first recess has a V-shaped cross section and an interior angle of the first bulge has a V-shaped cross section which corresponds to the V-shaped cross section of the first recess.
- the first bulge is trapezoidal.
- the first bulge has an arcuate edge which is opposite the inner angle and which extends upwards until it merges into the upper end of the main body.
- the arcuate edge protrudes upward relative to the end face of the housing body end region.
- an inner angle of the shoulder has an inverted V-shaped cross section and the sealing groove has an inverted V-shaped cross section which corresponds to the inverted V-shaped cross section of the shoulder.
- the shoulder is trapezoidal.
- the second bulge can be in locking engagement with the second recess.
- the second bulge is rectangular and the second recess has a rectangular shape which corresponds to the rectangular shape of the second bulge.
- the outside of the second bulge is offset inward by a certain distance relative to the outside of the first bulge, so that the outside of the second bulge and the outside of the first bulge form a step-shaped structure.
- a connector housing which comprises a connector housing assembly according to the first aspect of the invention and a hood, wherein an end face of the hood enclosing its opening when the hood and the housing body are in a closed state, partially directly touches an end face of the housing body end region and partially presses the arcuate edge of the first bulge, so that the first bulge is fully in positive engagement with the first recess.
- the upper end of the main body of the sealing ring with its lateral part partially encloses the hood.
- an electrical intermediate connecting element can be dispensed with thanks to the direct electrical contact of the hood with the housing body, which increases the electromagnetic shielding capability of the entire connector housing. Furthermore, the watertightness of the entire connector housing is increased by the sealing ring which is pressed between the end face of the hood and the housing body end region and which surrounds the interface between the hood and the housing body. In addition, the pressing surface of the sealing ring is enlarged thanks to the V-shaped configuration, which, in addition to ensuring watertightness, prevents the sealing ring from springing out when the connector housing is closed.

- the sealing ring 4 is located on the outer side of the housing body end region 11, as shown in the drawings, it is conceivable in another embodiment that the sealing ring is also arranged on the inner side of the housing body end region and thus the inside of the housing body - The end area is in locking engagement with the outside of the sealing ring.
- the housing body 1 is essentially rectangular overall and comprises two opposing first side walls 15 and two opposing second side walls 16.
- the outside of the housing body end region 11 of the housing body 1 has a polygonal shape and is relative to the side wall, for example the outside the first side wall 15 offset inward.
- the inside of the housing body end region has a polygonal shape and is offset inward relative to the side wall, for example the inside of the first side wall 15.
- a first recess 111 with a V-shaped cross section, a second recess 113 with a rectangular cross section and one between the first recess 111 and the are circumferentially on the outside of the housing body end region 11
- Second recess 113 arranged shoulder 112 is provided, which is substantially trapezoidal.
- An interior angle of the trapezoidal shape which is an alternating angle of an angle of the V-shaped cross section of the first recess 111, has an inverted V-shaped cross section.
- the shoulder can also have a different shape.
- the housing body end region 11 can furthermore comprise an end surface 114, which can be trapezoidal and serves to receive the associated end surface 21 of the end region of the hood 2.
- the first recess is located
- the side of the V-shape of the first recess 111 located on the outer side is shorter than the side located on the inner side in order to facilitate the insertion of the sealing ring 4.
- the angle enclosed by the shorter side and the horizontal axis of the horizontal plane is greater than 0 degrees in order to prevent the sealing ring from being released from the end region of the housing body prevent.
- the V-shape of the first recess 111 can have an angle which essentially corresponds to that of the inverted V-shape of the shoulder 112, or alternatively an angle deviating therefrom. Furthermore, in spite of the rectangular cross section in the embodiment according to FIG. 7, the second recess 113 can alternatively also have a different shape.
- the specific structure of the sealing ring 4 is discussed in greater detail below with reference to FIGS. 8 and 9.
- the sealing ring 4 is essentially rectangular and its inside has a polygonal contour, the polygonal contour of which is matched to the polygonal contour of the housing body end region 11.
- the seal ring 4 includes a main body 41, a first bulge 411 arranged on a side (inner side in the drawings) of the upper portion of the main body 41, a second bulge 413 arranged on a side (inner side) of the lower portion of the main body 41, and a Sealing out 412 arranged between the first bulge 411 and the second bulge 413.
- the main body, the first bulge and the second bulge form one piece with one another.
- the first bulge 411 is essentially trapezoidal, an interior angle of the trapezoidal shape having a V-shaped cross section which corresponds to the V-shaped cross section of the first recess 111.
- An edge of the first bulge 411 opposite the inner angle of the V-shaped cross-section is arcuate and extends upward until it merges into the inside of the upper end 414, so that the arcuate edge together with the upper end has a receiving section for receiving the end face the hood forms. It goes without saying that the first bulge can also have a different shape.
- the arcuate edge protrudes upwards relative to the end face 114 of the housing body end region 11.
- the inner side of the V-shape of the first bulge 411 is shorter than the outer side.
- the side of the V-shape located on the outer side runs parallel to the outside of the sealing ring, this side does not have to run parallel to the outside and can therefore alternatively intersect with the outside.
- the V-shape of the first bulge 411 can have an angle which essentially corresponds to that of the inverted V-shape of the sealing groove 412, or alternatively an angle deviating therefrom. Furthermore, in spite of the rectangular cross section in the embodiment according to FIG.
- the second bulge 413 can alternatively also have a different shape, for example a trapezoidal shape.
- the outside of the second bulge 413 is offset inwardly by a certain distance relative to the outside of the first bulge 411 to form a step-like structure. In other words, there is a distance d between the two components in the transverse direction, that is to say in the thickness direction of the sealing ring.
- the sealing ring is first pushed into the end of the housing body from above. Due to the step-like structure, which is formed by the outer edge of the first bulge 411 and the outer edge of the second bulge 413, the function of an assembly aid for the assembly of the sealing ring is provided and, in addition, the shoulder 112 of the housing body end region allows the sealing ring to move below avoided. The second bulge 413 then shifts downward beyond the shoulder 112 due to its elasticity and the first bulge 411 gradually slides into the first recess 111 of the housing body end region 11 and is thus in locking engagement.
- the shoulder 112 slides in the opposite direction into the sealing groove 412, the shoulder 112 serving as a stop and preventing the sealing ring from sliding down further.
- the second bulge 413 also slides over the shoulder 112 and finally into the second recess 113.
- the housing body end area is in locking engagement with the sealing ring, so that the sealing ring cannot move in the vertical direction and thus the sealing ring on the housing body. End area engages.
- the curved edge of the upper area of the first bulge of the sealing ring protrudes upward relative to the end surface of the housing body end area, the first bulge not being completely in positive engagement with the first recess of the housing body end area.
- the pressing surface of the sealing ring is enlarged, which increases the IP protection class of the sealing ring.
- FIG. 3 when the hood is pressed onto the housing body, the end face of the hood is pressed down against the curved edge of the first bulge of the sealing ring, so that due to the elastic deformation of the sealing ring, the first bulge is shifted further downwards to be fully in positive engagement with the first recess.
- Such a V-shaped structure prevents the sealing ring from springing out of the housing body end area under pressure.
- the upper end of the main body of the sealing ring with its side part partially encloses the hood, i.e. the outside of the hood as in FIG. 3, in order to protect against ingress of water and dust enable.
