ABSTRACT:
According to the state of the art, it is known to link the soldering terminal plates (10) of loudspeakers by riveting them to the loudspeaker frame. It is also known to relieve the strain on loudspeaker connection cables, which extend between the soldering terminal plate (10) and the signal source. According to the state of the art, this is accomplished most of the time by pressing the connection cable with a so-called cable tie against the magnet system of the loudspeaker. It is furthermore known to clamp the connection cable with a bracket formed on the loudspeaker frame (12). To simplify the production, the invention equips the soldering terminal plate (10) with catch hooks (13), which securely attach the soldering terminal plate (10) to the loudspeaker frame (12), after linking it to the crosspiece (11). The strain-relief for the connection cable (22) is established in such a way, that a safety bolt (18) can be inserted into openings (16) in the soldering terminal plate (10). When the safety bolt (18) has reached its final position on the soldering terminal plate (10), the safety bolt (18) locks onto the soldering terminal plate (10). The shape of the soldering terminal plate (10) and the safety bolt (18) is such, that when the safety bolt (18) has reached its final position, it clamps down on a connection cable (22) that is placed between these two components. This provides an effective strain-relief in the area of the soldering terminal plate (10).
