Definitions
- the invention relates to an electrical double flat spring contact according to the preamble of claim 1.
- Such a double flat spring contact is known from DE-A1 32 48 078.
- the slot in the spring base part is arranged on the same circumferential side as the slot in the reinforcement spring base part.
- the over or reinforcement spring cannot prevent the spring base from expanding.
- the invention has for its object to provide an electrical double flat spring contact, the spring of which not only increases the spring force, but also prevents the spring base from expanding.
- the double flat spring contact according to the invention is secured against widening in the area of the spring base part, since the reinforcing spring clamps radially to the spring base part with an undivided side wall or the top wall. If the slots are arranged offset from one another by 90 o , this enables the connection of two symmetrically arranged barbs on the spring, one on the floor and one on the ceiling, which can lock the contact securely in a housing. This arrangement also enables in a particularly simple manner the locking between the two spring parts shown in the further subclaims, the pushing on of the reinforcement spring in two rotational positions and a particularly narrow design with consequently high packing density in the contact housing.
- Figure 1 shows an electrical double flat spring contact in side view.
- Figure 2 shows the double flat spring contact according to Figure 1 from below.
- Figure 3 shows a reinforcement spring in side view.
- Figure 4 shows the reinforcement spring of Figure 2 in plan view, partially broken.
- FIG. 5 shows the section V-V in FIG. 4.
- Figure 6 shows the double flat spring contact with the reinforcement spring.
- FIG. 7 shows the section VII-VII in FIG. 6.
- the electrical double flat spring contact 1 made of sheet metal is composed of a rear, U-shaped insulation claw 2 and a corresponding conductor wire claw 3, which merges via an intermediate piece 4 into a box-shaped spring base part 5.
- the spring base part 5 is composed of the cover part 6, the side walls 7 and 8 and the bottom parts 9 and 10. Between the bottom parts 9 and 10 a longitudinal separation slot 11 is arranged.
- the bottom parts 9 and 10 are the first pair of spring arms 12, the ceiling part 6 is the second pair of spring arms 13 formed.
- the separating slot 11 between the bottom parts 9 and 10 between the pair of spring arms 12 continues as a slot 11a.
- the slot 14 between the pair of spring arms 13 ends at the front edge 15 of the cover part 6 of the spring base part 5.
- Both side walls 7 and 8 have recesses 16 and 17, which widen towards the spring arm pairs 12 and 13 via slopes 18 and 19. Both side walls 7 and 8 are of identical design and are arranged symmetrically to the ceiling part 6 and to the bottom parts 9 and 10.
- the recesses 16 and 17 comprise radial stop edges 20 and 21.
- the reinforcement spring 25 (FIG. 3) made of sheet metal is composed of a rear box-shaped reinforcement spring base part 26 (hereinafter referred to only as the base part). and two adjoining reinforcing spring arm pairs 27 and 28. Between the reinforcing spring arm pairs 27 and 28, a slot 29 and 30 is arranged, each of which ends at the base part 26.
- the base part 26 is composed of the base part 31, a ceiling part 32, a first side part 33 and a second side part 34.
- the side part 34 is separated by a central longitudinal slot 35 and has two on both sides of the longitudinal slot 35 near the front edge 36 of the base part 25 inwardly to 90 o angled tabs 37 (FIGS 3 to 5).
- Latch spring arms 38 and 39 are punched out of the base part 31 and the cover part 32, so that there is a recess 40 and 41, respectively.
- the ceiling part 32 ends with the edge 42, which is opposite the inner edge 43 of the recess 40 at a distance and in the same plane.
- the assembly to the complete double flat spring contact takes place by pushing the reinforcement spring 25 onto the spring base part 5.
- the reinforcement spring 25 with its base part 26 is pushed over the spring arm pairs 12 and 13, in such a way that the spring arm pairs 27 and 28 over the spring arm pairs 12 and 13 come to rest.
- the tabs 37 enter one of the recesses 16 or 17.
- the introduction is facilitated by the bevels 18 and 19, respectively. Sliding on is possible in two positions of the reinforcement spring 25, i.e. the tabs 37 can either be inserted into the left or right side wall 7 or 8 of the spring contact 1, and the slot 35 of the reinforcement spring 25 lies either to the side of the left or the right Side wall 7 or 8 of the spring contact 1.
- the spring base part 5 resists widening: by inserting a plug tongue between the spring arm pairs 12 and 13, an expanding force is transmitted to the spring base part 5, which is trying to push it apart. This spreading force is transmitted to the base part 26 of the reinforcement spring 25, which is also pressed apart. However, the spreading force acting on the reinforcement spring 25 is absorbed by the tabs 37, which are supported on the rigid stop edges 20 and 21 of the spring contact 1. An expansion of the base part of the reinforcing spring 25 and thus the base part 5 of the spring contact 1 is excluded.
- the illustrated embodiment can in particular be modified so that the axial locking does not take place as described above over the ceiling or floor parts, but over the side wall parts of the spring parts involved.
- the tabs 37 can also be used for this purpose.
