Abstract
Method and arrangement for providing a grounding element (1) configured for assuring an electrical connection between a structural element and an electrical terminal and that includes a first portion (2) provided with a thread (5), a second portion (3) provided with a thread (6), and a central section (4) having a portion (4a) with at least one projecting ridge (7) that connects the first portion (2) to the second portion (3). The central section (4) has a first contact surface (8) in the plane where the central section (4) is connected to the second portion (3).
Claims9
A grounding element (1) for making possible an electrical connection between a structural element and an electrical terminal, said grounding element (1) comprising:
- a first portion (2);
- a second portion (3) provided with a thread (6);
- a central section (4) connecting the first portion (2) to the second portion (3) and the central section (4) having a first contact surface (8) in a plane where the central section (4) is connected to the second portion (3);
- and
- the first portion (2) having a thread (5) and the central section (4) having a portion (4a) with at least one projecting ridge (7).
An elongate grounding element for affecting and facilitating an electrically grounded connection, the elongate grounding element comprising:
- an elongate body having a longitudinal axis and at least an externally threaded portion, said threaded portion having an insertible portion configured for non-threaded engagement with a support member when said threaded portion is inserted through a provided aperture in the support member;
- and
- a means for enhancing electrically conductive contact between the elongate body and the support member, said enhancement means comprising elongate ridges radially extending off of a central portion of the elongate body, said central portion being configured for non-twisting insertion into the provided aperture in the support member in a direction substantially parallel to the longitudinal axis of the elongate body, said elongate ridges forming an interference fit with the support member at a periphery of the provided aperture.
A method for providing an elongate grounding element and affecting and facilitating an electrically grounded connection between the elongate grounding element and a receiving support structure, the method comprising:
- providing an elongate grounding element having an elongate body establishing a longitudinal axis thereof and having at least an externally threaded portion;
- inserting a part of said threaded portion through a provided aperture in the support member and thereby establishing non-threaded engagement of the elongate grounding element with the support structure;
- enhancing electrically conductive contact between the elongate body and the support member by causing elongate ridges that radially extend off of a central portion of the elongate body to non-twistingly press into the provided aperture in the support member in a direction substantially parallel to the longitudinal axis of the elongate body;
- and
- forming an interference fit between the elongate ridges and the support member thereby affecting and facilitating an electrically grounded connection between the elongate grounding element and the support structure.
