Embodiment
Fig. 1 shows the assembly that connects according to execution mode of the present utility model under operating position.The assembly that connects for pass wall 4 with sealing means guiding cable 2 of Fig. 1 comprises mechanical sealing member and EMC seal.
Mechanical sealing member is arranged to prevent that deleterious particle from passing connects assembly and it comprises that elasticity connects seal 6 and mounting panel 8, elastomeric grommet 6 is attached to mounting panel 8, makes the first of elastomeric grommet 6 be positioned on first side in axial direction of mounting panel 8 and the second portion of elastomeric grommet 6 is positioned on second side in axial direction of mounting panel 8.Elastomeric grommet 6 is arranged to prevent that deleterious particle from passing through between the sheath 24 of cable and mounting panel 8, the second portion of elastomeric grommet 6 can see well in Fig. 2 that Fig. 2 illustrates the assembly that connects of Fig. 1 from radial direction.
The axial direction that connects assembly is that cable extends through the direction that connects assembly under operating position.When cable was loaded with electric current under operating position, the sense of current was parallel to axial direction.
Mounting panel 8 is made by electric conducting material and is attached to wall 4 with electrically conducting manner.Mounting panel 8 can be fixed to wall 4 by screw not shown in Figure 1.In some embodiments, the seal of being made by electric conducting material can be installed between mounting panel and the wall.
Mounting panel is smooth basically element, and under situation about using, the surface normal of mounting panel is parallel to axial direction.In Fig. 1, along being observed, the angular direction connects assembly from first side of mounting panel 8.
The EMC seal arrangement becomes to provide electromagnetic sealing.The EMC seal comprises the coronal 10 with a plurality of contact protuberances 12, and each in these contact protuberances is made by conductive sheet metal.Coronal 10 is attached to the mounting panel 8 of mechanical sealing member with electrically conducting manner, and therefore coronal 10 is grounding to wall 4 via mounting panel 8.In axial direction observe, coronal 10 is positioned on first side of mounting panel 8.Radially observe, the first of elastomeric grommet 6 extends in the coronal 10.The radial direction that connects assembly is the direction vertical with the axial direction defined above that connects assembly.
The contact protuberance 12 of coronal 10 is tightened up by the concentric earthing conductor 22 of wire rope band 14 against cable 20.In other words, with one heart earthing conductor 22 is connected to wall via coronal 10 and mounting panel 8 with electrically conducting manner.The concentric earthing conductor 22 of cable 2 exposes by the sheath 24 of peeling cable off.Earthing conductor 22 can be seen in Fig. 2 well with one heart.
According to an alternative execution mode, be placed with copper strips between the protuberance to improve conductivity concentric earthing conductor and the contacting of coronal of cable.
Fig. 3 shows the entity that is formed by coronal 10 and the mounting panel 8 that attaches to coronal 10.As seeing in Fig. 3, coronal 10 is arranged to surround in all directions cable.In other words, coronal 10 is arranged to provide the ground connection of cable 360 degree.Fig. 3 also shows the outermost portion in each contact protuberance 12 of coronal 10, and namely apart from the part of mounting panel 8 certain distances, it is radially outwardly-bent.The bandy shape of contact protuberance 12 prevents that the wire rope band from slipping away from the top in axial direction of coronal 10.
Coronal 10 directly is attached to the first surface of mounting panel 8, and this first surface is the upper surface of mounting panel 8 in Fig. 3.This direct joint can comprise solder joints.According to an alternative execution mode, thisly directly attachedly can comprise that flanging engages (crimped joint) or coronal and mounting panel is integrated.
Mounting panel 8 has the circular port that is arranged to admit cable and surrounds the elastomeric grommet of this cable.According to an execution mode, the neighboring of elastomeric grommet is provided with the groove at the edge of the circular port that is arranged to admit mounting panel, elastomeric grommet is arranged to closely press the first surface of mounting panel and the second surface of mounting panel, and second surface is positioned on the side of first surface dorsad of mounting panel.
Elastomeric grommet 6 comprises the rubber grommet of the sheath 24 that is arranged to engage cable 2.First in elastomeric grommet 6---is positioned at when in axial direction observing on first side of mounting panel---and is provided with first contact site, and the sheath 24 of first contact site on first side that is positioned at mounting panel that is arranged under the situation about using with cable 2 contacts.The second portion of elastomeric grommet 6---is positioned at when in axial direction observing on second side of mounting panel---and is provided with second contact site, and the sheath 24 of second contact site on second side that is positioned at mounting panel that is arranged under the situation about using with cable contacts.When in axial direction observing, first contact site of elastomeric grommet 6 is apart from the second contact site certain distance of elastomeric grommet 6, and namely under situation about using, elastomeric grommet 6 does not contact with the sheath 24 of cable 2 on the part between first contact site and second contact site.
Fig. 4 shows the preformed member of the coronal 10 of Fig. 3.Fig. 4 shows the preformed member of the coronal of being made by sheet material.The bottom that the top of preformed member is provided with a plurality of contact protuberances and preformed member has a plurality of connection protuberances that are arranged to be fixed to for the coronal 10 that will make mounting panel.Coronal 10 comes moulding by the columnar shape basically that the preformed member with Fig. 4 is rolled into as shown in Figure 3.According to an execution mode, before the coronal that will make is fixed to mounting panel, the end of the preformed member of coronal is attached at together.According to an alternative execution mode, be rolled into basically that the preformed member of the coronal of columnar shape is fixed to mounting panel, coronal is because the joint between coronal and the mounting panel and keep its columnar shape basically.
Be apparent that to those skilled in the art, can implement basic thought of the present utility model with different ways.Therefore, the utility model and its execution mode are not limited to above-mentioned example, but can change within the scope of claim.
