Abstract
A connection assembly has a first structural component, a second structural component and a contacting element. A first connection section and a second connection section of the structural components face each other, forming a slot between them. The first structural component comprises a groove in the first connection section, the groove being confined at least by two straight walls. The contacting element comprises a contacting portion being a helix, the contacting portion being in physical contact with the second connection section of the second structural component and with the straight walls of the first structural component. Further, a housing and an antenna are shown.
Claims15
A connection assembly for avoiding or alleviating passive intermodulation of connected structural components, having a first structural component, a second structural component and a contacting element for providing a galvanic connection between the first structural component and the second structural component;
- wherein the first structural component comprises a first connection section and the second structural component comprises a second connection section, the first connection section and the second connection section facing each other, forming a slot between them;
- wherein the first structural component comprises a groove in the first connection section open towards the second connection section, wherein the groove extends in a longitudinal direction of the slot and is confined at least by two straight walls;
- and
- wherein the contacting element comprises a contacting portion being a helix, the contacting portion extending in the longitudinal direction of the slot and being in physical contact with the second connection section of the second structural component and in physical contact with the straight walls of the first structural component.
A housing, in particular for an antenna or a mobile communication cell site, comprising a housing part, a cover part and at least one connection assembly for avoiding or alleviating passive intermodulation of connected structural components, having a first structural component, a second structural component and a contacting element for providing a galvanic connection between the first structural component and the second structural component;
- wherein the first structural component comprises a first connection section and the second structural component comprises a second connection section, the first connection section and the second connection section facing each other, forming a slot between them;
- wherein the first structural component comprises a groove in the first connection section open towards the second connection section, wherein the groove extends in a longitudinal direction of the slot and is confined at least by two straight walls;
- wherein the contacting element comprises a contacting portion being a helix, the contacting portion extending in the longitudinal direction of the slot and being in physical contact with the second connection section of the second structural component and in physical contact with the straight walls of the first structural component;
- and
- wherein the housing part comprises the second structural component of the connection assembly and the cover part comprises the first structural component of the connection assembly or vice versa.
An antenna, in particular for a mobile communication cell site, comprising (a) a housing comprising a housing part, a cover part, and at least one connection assembly and/or (b) the at least one connection assembly, the at least one connection assembly being for avoiding or alleviating passive intermodulation of connected structural components and having a first structural component, a second structural component and a contacting element for providing a galvanic connection between the first structural component and the second structural component;
- wherein the first structural component comprises a first connection section and the second structural component comprises a second connection section, the first connection section and the second connection section facing each other, forming a slot between them;
- wherein the first structural component comprises a groove in the first connection section open towards the second connection section, wherein the groove extends in a longitudinal direction of the slot and is confined at least by two straight walls;
- and
- wherein the contacting element comprises a contacting portion being a helix, the contacting portion extending in the longitudinal direction of the slot and being in physical contact with the second connection section of the second structural component and in physical contact with the straight walls of the first structural component.
