Battery pole terminal
View Patent ↗A battery pole terminal, having an annular section, which surrounds a cylindrical or conical receiving space at least in sections in a circumferential direction, the annular section having an interruption with respect to the circumferential direction with two opposite edges. A gripping section for a clamping mechanism is provided at each of the edges. Furthermore, the battery pole terminal has a clamping mechanism which acts on the gripping sections and can exert a clamping force on the edges, pushing the opposite edges toward each other. A force limiting mechanism is provided which, when a minimum distance between the edges is reached, prevents an increase in the clamping force on the gripping sections.
1. A battery pole terminal, having an annular section, which surrounds a cylindrical or conical receiving space at least in sections in a circumferential direction, the annular section having an interruption with respect to the circumferential direction with two opposite edges, and a gripping section for a clamping mechanism being provided at each of the edges, and having the clamping mechanism which acts on the gripping sections and can exert a clamping force on the edges, pushing the opposite edges toward each other, wherein a force limiting mechanism is provided which, when a minimum distance between the edges is reached, prevents an increase in the clamping force on the gripping sections, wherein the clamping mechanism has two clamping elements which can be moved relative to each other, and wherein the force limiting mechanism blocks movement of at least one clamping element when the minimum distance is reached by directly contacting the at least one clamping element.
2. The battery pole terminal as claimed in claim 1 , wherein the force limiting mechanism blocks movement with at least one stop when the minimum distance is reached.
3. The battery pole terminal as claimed in claim 1 , wherein the force limiting mechanism has a spacer element, with a first stop, on which a contact surface of a first gripping section and/or of a first clamping element lies when the minimum distance is reached.
4. The battery pole terminal as claimed in claim 1 , wherein the spacer element further includes a second stop on which a contact surface of a second gripping section and/or of a second clamping element lies when the minimum distance is reached.
5. The battery pole terminal as claimed in claim 3 , wherein the spacer element is a separate component which is held at the clamping mechanism and/or at at least one of the gripping sections.
6. The battery pole terminal as claimed in claim 5 , wherein the spacer element is a cylindrical sleeve, and the first and/or the second stop is/are provided at the axial ends of the sleeve.
7. The battery pole terminal as claimed in claim 3 , wherein the spacer element is formed integrally with a clamping element and/or with a gripping section.
8. The battery pole terminal as claimed in claim 7 , wherein a first clamping element has a screw and the second clamping element has a nut, wherein the nut is screwed onto the screw to apply the clamping force.
9. The battery pole terminal as claimed in claim 4 , wherein the spacer element is a separate component which is held at the clamping mechanism and/or at at least one of the gripping sections.
10. The battery pole terminal as claimed in claim 4 , wherein the spacer element is formed integrally with a clamping element and/or with a gripping section.
