Abstract

The connection terminal has a bus bar (4) with an arrangement for contacting at least one conductor to be connected and a protective conductor connection (14,16,18) for joining the terminal to a profiled protective bus bar. The protective conductor connection is joined to the bus bar in one piece. The protective conductor connection has a base section (14) and a sprung latch section (16).

Description

The invention relates to a terminal, in particular terminal, with a busbar and at least one separately formed and electrically conductive associated spring clamp element, which is suitable for screwless mounting a conductor by a conductor end with a spring force of the Federerklemmelements excess force (or in the with an auxiliary tool open spring clamp element) is inserted and is sufficiently contacted by spring force. Such terminals are particularly common in the home and lead by eliminating screwing to considerable time savings during installation.

Such a terminal is, for example. From the DE 27 24 324 in which in holders of a current corner a leaf spring with a middle and two opposite, opposite curved turns of turns is used, each free leg are directed obliquely to contact areas of the busbar and rest against it with spring force. A disadvantage of this known Ausfühning is that the thickness of the terminal in the direction of arrangement aufgnind the fact that the leaf spring, seen in the direction of assembly, in front of the busbar is always greater than the thickness of the leaf spring, which in turn must be at least as large as the biggest picking up wire diameter.

From the DE 100 53 035 a leaf spring clamp is known which comprises a carrier block of a profile strip made of brass, to which a leaf spring is clamped. A disadvantage here is that the carrier block has a considerable material cross-section, which leads to corresponding material costs in practice.

From the DE 42 31 244 is an electrical terminal with a spring-loaded clamping element known, which is disadvantageous in terms of the minimum width to be achieved in the direction of arrangement similar to that of the DE 27 24 354 known terminal, since there is a clamping of an inserted conductor effecting spring leg, seen in the direction of assembly, before areas of a bus bar forming a terminal chamber for the conductor, whereby the thickness of the terminal in the direction of arrangement is necessarily greater than the thickness of the spring leg.

Finally, out of the DE 195 47 557 an electrical clamp with spring force clamping elements known, wherein the spring force clamping elements are integrally bent from spring steel and engages a spring end portion through a conductor receiving opening in a mounting end portion of the spring force clamping element. In this type, the spring force clamping element must be opened with a separate actuation process, before the conductor can be inserted, ie a mounting only on pressure is not possible.

Fig. 1 to 9 explain a first embodiment of a terminal according to the invention in the form of a terminal block 1, which in side and perspective view in Fig. 1 and 2 is shown. The terminal block 1 has in a conventional manner a relatively narrow in the direction of arrangement 2, insulating plastic housing 3, which serves the insulating support of a busbar 4. Fixedly connected to the busbar are two spring clamping elements 6, each having a spring leg 8 and a contact leg 10 and are conductively connected to the busbar 4.

To be connected conductors can be mounted in a time-saving plug-in technology by passing through a housing opening 14 and inserted between spring leg 8 and contact leg 10 in the direction of arrow 12, wherein the spring leg 8 is opened away from the contact leg 10, so that a contact end portion of the connected Ladder between spring and contact legs is clamped. To release the conductor, a suitable tool, for example. A screwdriver, introduced through a further housing opening 16 and the spring leg 8 is opened become. In order to avoid excessive bending back of the spring leg, a stop 18 is provided.

Fig. 3 to 7 serve to explain the held in the housing 3 busbar and spring clamping elements. As 6 and 7 show, the busbar 4 made of flat sheet material, in particular tinned copper sheet, produced by punching and has two U-shaped receiving recesses 20 for each spring clamp element 6, each receiving recess has a base portion 22 and two substantially perpendicular thereto oriented side portions 24. In the region of each base section 22, a rivet projection 26 is formed, the free end of which has a chamfer 28.

In each case, laterally adjacent to the receiving recesses 20, two spring contacts 30 are formed by narrowing and widening punch-outs, each receiving one in the direction of the arrow 29 (FIG. Fig. 1 ) Brückerfingers einzusteckenden serve.

4 and 5 explain the execution of the spring clamp elements 6. Although the spring clamping elements could be one piece, in the illustrated embodiment, for better function, a material allocation made with respect to "springs" and "conduction", each spring clamp element 6 in two parts consisting of a spring steel spring leg 8 and a essentially U-shaped contact leg 10 is formed, which are connected by rivets 9 in the region of a subsection 8a, 10a. The contact leg 10 is provided in the region of a contacting surface 10b with corrugations 31, which serve on the one hand an improved contact and on the other hand a better mechanical retention of an inserted conductor.

The contact leg 10 further has a slot-shaped opening 32 for attachment to a rivet or clamping projection 26 of the busbar. Two forked Lugs 34 overlap on both sides a projection 36 of the busbar 4 in order to prevent a transverse movement of the contact leg 10.

Based Fig. 1 to 3 It is clear that the spring clamp element is supported on the one hand with the spring leg 8 and on the other hand with the contact leg 10 against the side portions 24 of the bus bar 4 and thus, even if the spring leg 8 generates a relatively large spring force in the region of the contact leg 10 record any bending stress must, since the spring force is completely absorbed by the busbar. The contact rail 10 therefore needs to be designed only with regard to the currents occurring, but not with regard to spring forces, resulting in a significant material savings. Another advantage is that the width of the terminal ( Fig. 3 ) in the direction of assembly 2 with the width b ( Fig. 4 ) of the Federklemmelements, ie of contact leg 10 and spring leg 8 matches, which in turn is a consequence of the structural design that does not require any bent reinforcing areas on spring or contact legs.

To improve the contact between spring clamp elements and busbar, the rivet or clamping projections 26 can be deformed after attaching the spring clamp elements, so that the spring clamp elements are firmly and permanently connected to the busbar. Alternatively or additionally, a connection by soldering or welding is possible.

Another advantage of the terminal according to the invention according to Fig. 1 to 7 is that Brückerverbindungen can be made in the simplest way by punched in one piece with the bus bar spring contacts 30, which serve to accommodate comb-like Brückerfinger, which in turn are extremely inexpensive to produce. FIGS. 15 and 16 For the sake of clarity, FIG. 1 shows a bridge 160 with a web 161 from which five bridge fingers 162 depart, in a manner known per se.

8 and 9 illustrate a variant of a bus bar 4 'according to the invention, which serves with a protective conductor connection 38 for latching onto a protective conductor rail 40, while the bus bar 4' otherwise corresponds to the conductor rail 4.

10 to 14 show a further embodiment of a terminal according to the invention, wherein 10 and 11 in side and perspective view, accordingly Fig. 1 and 2 , a terminal 101 with an insulating plastic housing 103, a busbar 104 and spring clamp elements 106 show. Regarding the use and function of the terminal 101, reference is made to the relevant explanations Fig. 1 and 2 directed.

The busbar 104 of the terminal 101 according to Fig. 13 is strip-shaped made of a flat sheet material, in particular of a tin-plated copper alloy, the width of which, in contrast to the embodiment according to Fig. 1 to 9 essentially coincides with the width / thickness b of the spring clamping elements 6, as Fig. 14 shows.

Fig. 12 shows a spring clamp element 106 in an enlarged view, it can be seen that a central portion of the Federklemmelements with spring leg 108 corresponds to the spring clamp element 6 of the first embodiment, while the spring clamp element 106 is additionally provided with Abstützansätzen 150, with which it is supported relative to the bus bar 104. Free ends 150a of the support sections 150 have cutouts 152 so that the support extensions can be resiliently inserted into corresponding openings 154 of the busbar 104. For better contacting and mechanical fastening, the free ends 150a can be riveted or deformed in the region of the punched-out portions 152 after insertion into the openings 154, with a non-detachable connection being produced. Again, a soldering or welding connection is alternatively or additionally possible.

The bus bar 104 also has bridge openings 156 for receiving bridge fingers.

Substantial advantages of the above-described embodiment over the prior art are that the material of the spring clip element 106 (more specifically, the contact leg 110) including the support sections 150 can be made of a relatively thin material whose cross-section depends on the expected current strength, while the mechanical rigidity of the spring clip is maintained by the support against the bus bar 104. In addition, the terminal has a minimum width b in the mounting direction, since all components are formed of flat material extending in the width direction, without transversely bent, the mechanical stiffening serving areas are required, the width of the terminal by the amount of material thickness d ( Fig. 12 ) would increase.

Fig. 17 to 21 illustrate a further embodiment of a terminal according to the invention in the form of a terminal 201 with a busbar 204 and spring clamping elements 206, with respect to use and function of the terminal 201 to the explanations to Fig. 1 to 9 referenced.

In contrast to the first embodiment, the busbar 204 of the terminal 201 is not completely flat, but has two perpendicular to an extension plane of the busbar angled regions 270 are formed by the contact surfaces 271, the contacting of a between these and a spring leg 208 of the spring clamping element 206 inserted conductor serve. The function of the Federerklemmelements 206 thus corresponds to that of the Federerklemmelements 6 of the first embodiment, with the difference that the spring clamp member 206 is integrally formed in the form of a U- or C-shaped spring and does not require a separate contact leg, since it is formed by the power machine 204 As Fig. 17 to 21 Further, a stop 218, corresponding to the stop 18 of the first Ausfrührungsform, integrally made together with the busbar 204 made of sheet metal, resulting in further advantages both in terms of manufacturing and function. On the one hand, a one-piece production is cheaper, and on the other hand is possible because the stop is not made of plastic, but of metal, possibly a significant increase in the spring constant (spring hardness) of Ferderklemmelements 206 possible, since the spring leg 208 with increasing deflection in the direction of the stop 218 increasingly applies to the curved stop surface, so that a shortening of the effective length of the leg and thus a stronger spring action results.

Fig. 19 to 21 illustrate the design and manufacture of the bus bar 204, which consists of a single stamped sheet metal blank ( Fig. 21 ) is produced by a few simple bending operations. A protective conductor terminal 238 can be provided without much extra effort.

In all embodiments of the present invention, a decisive advantage is that the width of the terminal or terminal (dimension in Anreichrichtung 2) is not greater than the width b of the flat or spring element, so that a maximum spring force with minimum width of the terminal is reached.
