Definitions
- Tension spring connections of this type are known in their construction and are commercially available. For such tension spring connections, it is of great importance when operating the Tension spring for inserting a conductor to ensure that the Tension spring does not exceed permissible values and due to plastic deformation the tension spring does not deteriorate. This is the mainspring supported in their position on the conductor rail so that when they are actuated, in particular during their opening movement, an overextension of the spring is prevented.
- the insertion opening 9 is above the tension spring 1 in the housing Pocket 4 indicated, through which the tension spring 1 in the direction of assembly direction 7 in the housing pocket 4 can be inserted.
- the Tension spring 1 is provided with recesses 2 and relative to stop elements 3 is arranged, also fixed to the housing in the lower region of the housing pocket 4 are shown in principle.
- the tension spring 1 is in its lower end
- the area assigned to the housing pocket 4 has been provided with recesses 2 in such a way that that the recesses 2 release 1 space in the inserted position of the tension spring for the stop elements 3, which are arranged on the front of the tension spring 1 Walls of the housing pocket 4 are formed.
- the movable leg of the tension spring 1 has more Sections 18 which, when this leg is deformed, correspond to the associated Surfaces of the stop elements 3 can, as in FIG. 4, otherwise is identical to FIG. 3.
- the permissible pivoted position of the freely movable Leg of the tension spring 1 results in a more or less flat Contact between the more ready sections 18 of the movable leg of the Tension spring 1 and the contact surfaces of the stop elements 3. This is a inadmissible actuation of the free leg of the tension spring 1 in the direction of the actuation directions 8 safely prevented.
- FIGS. 5 and 6 show a connection element analogous to FIGS. 4 and 5, the undeformed position in FIG. 5 and the deformed position in FIG. 6 the tension spring 1 is indicated.
- the connection element of Figures 5 and 6 acts it is a connection element with an actuation primarily in accordance Figure 5 horizontal direction according to arrow VIII.
- This results in constructive Changes in the busbar 11 and of housing components in this context are not important.
- the dimensional design of the stop elements 3 which due to the assembly of the Tension spring 1 in the direction of the mounting direction 7 not so far into that of the tension spring 1 enclosed interior protrude and therefore, as can be seen in Figure 6, a not so clearly large support of the movable leg of the tension spring 1 allow.
- Through constructive measures, especially the shape of the Busbar 11 and the tension spring 1 can also the stop element 3 according to figures 5 and 6 varies and there is greater coverage between the wider ones Sections 18 of the tension spring 1 and the stop elements 3 can be reached.
