| 摘要 |
The invention relates to an explosion-proof arrangement (22) comprising an electrically conductive bolt (23) which is composed of a rigid material which is not deformable in the radial direction. The bolt (23) is coaxially enclosed by an electrically insulating, elastically deformable sleeve (30) in a central section (23a). The sleeve (30) is in turn coaxially surrounded by a connecting section (41) of a plastically deformable connecting body (40). Plastic deformation of the connecting section (41) reduces the outside dimensions of said connecting section and said connecting section presses inward against the sleeve (30) which is supported on the bolt (23). This results in a force-fitting and optionally additionally interlocking connection which forms a structural unit comprising the connecting body (40), the sleeve (30) and the bolt (23). When the structural unit is produced, a first stop face (26) which is provided on the bolt (23) obliquely or radially in relation to the longitudinal axis (L) of the bolt (23) bears against a correspondingly associated first mating stop face of the sleeve (30). In addition, a second stop face can be provided on the sleeve (30), said second stop face being oriented obliquely or radially in relation to the longitudinal axis (L), and an associated second mating stop face (46) of the connecting body (40) bearing against said second stop face. |
