Description

The present invention relates to a spring-loaded terminal with a bus bar, which is provided for contacting an electrical conductor, in particular a stranded conductor, and with a spring which is provided for fixing the electrical conductor in the spring-loaded terminal.

Such spring terminals in one embodiment as a direct plug-in terminals (push-in) with a compression spring which presses the conductor against the busbar, are known in various embodiments. They differ mainly due to their application, for example, depending on the required current carrying capacity of the busbar, the spring force of the clamping spring and / or their installation conditions, especially their size. Here are a simple installation and a cost-effective production permanently Asked for such a terminal.

The publication US Pat. No. 7,997,915 B2 discloses a wire end ferrule, at one end of a direct plug-in terminal for non-detachable connection of an electrical conductor is arranged. The direct plug-in terminal comprises a current-carrying clamping cage for electrically contacting the electrical conductor and a spring for fixing the electrical conductor. The spring has a pivotable clamping leg, which is positioned at not inserted into the direct plug-in electrical conductor on a retaining edge, so that a free space for the electrical conductor kept and this is inserted into the clamping cage. When inserted into the direct plug-in terminal, the holding means is displaced so that the clamping leg is released and pivoted. The pivoted clamping leg presses the electrical conductor to the clamping cage.

Object of the present invention is to provide a spring terminal, in particular an attachable spring terminal, in particular for stranded conductors, which improves this mechanism, so that the electrical conductor from the spring terminal is as possible without damage again solvable.

The object is achieved with a spring-loaded terminal according to claim 1. Advantageous embodiments can be found in the dependent claims.

It is provided a spring terminal, comprising a bus bar for contacting an electrical conductor, and a clamping spring for fixing the elektrisehen Ladder in the spring-loaded terminal, wherein the clamping spring has a pivotable about a pivot axis in a pivoting clamping leg, which is pivotable from a locking state in which it is locked to a retaining means by moving the inserted into the spring terminal electrical conductor in a clamping state, in the he is unlocked from the holding means and presses the electrical conductor against the busbar.

The holding means is preferably arranged on a retaining spring, which is pivotable about a second pivot axis in and against a second pivoting direction. By giving away the retaining spring, the holding means is therefore pivotable so that the clamping leg is unlocked.

In this case, the retaining spring preferably has a pressure surface, which further preferably extends transversely to the sliding direction. It is preferred that the retaining spring is pivotable by pressure on the pressure surface in the second pivoting direction.

When moving the inserted into the spring clamp electrical conductor in the sliding direction of this device comes into contact with the pressure surface. When pushing further in the sliding direction, it presses on the printing surface. As a result, the retaining spring is pivoted in the second pivoting direction, so that the clamping leg is unlocked by the holding means and pivoted in the pivoting direction.

In principle, a pressure surface at a different angle to the sliding direction is conceivable. The arrangement of the pressure surface transversely to the sliding direction is due to the large in this arrangement attack surface for the electrical conductor but advantageous.

In order to enable a free pivoting of the clamping leg in and against the pivoting direction, it is preferred that the pressure surface is arranged in the sliding direction below the holding means.

It is also particularly advantageous that the spring-loaded terminal has a sliding sleeve which serves as an insertion aid for the conductor and which facilitate the insertion of such finely stranded conductors, which are particularly flexible.

According to an advantageous development, the spring clamp is characterized in that it comprises a return means, which is provided for pivoting back of the clamping leg. The clamping leg is zurückschwenkbar by moving the return means against the pivoting direction of the clamping state in the locking state. As a result, a previously clamped in the spring terminal clamp in the terminal state conductor of the spring terminal in the latching state can be removed again.

Preferably, the return means protrudes in the clamping state of a terminal housing of the spring terminal. This makes it very easily accessible and very easy to push in the sliding direction. The handling of the spring terminal is therefore feasible for full conductors and stranded conductors in the same way and very simple.

It is also preferred that the return means is jammed in the clamping state between the clamping leg and the terminal housing in this, so that it does not come off the terminal housing.

The clamping spring, the busbar and / or the retaining spring are preferably made as stamped and bent parts made of sheet metal, preferably made of strip material, since this is inexpensive possible with conventional methods.

In this case, the busbar is preferably made of an electrically highly conductive material, in particular of a copper-containing metal. Clamping spring and retaining spring are preferably made of a material with good spring properties.

a clamping spring and a retaining spring of the spring terminal Fig. 1 ,

Fig. 2 shows a spring terminal 1, here an attachable terminal, with a bus bar 2 for contacting an electrical conductor, acting as a compression spring clamping spring 3, which is provided for clamping the electrical conductor 6 in the spring terminal 1, and with a retaining spring 4th

On the retaining spring 4, a holding means 41 is arranged, on which the clamping spring 3 is locked in a latching state R.

The busbar 2, the clamping spring 3 and the retaining spring 4 are arranged in a terminal housing 12, which is preferably made of an electrically insulating material, in particular of a plastic. In the terminal housing 12, an insertion opening 11 for insertion of the electrical conductor 6 is provided.

The illustrated electrical conductor 6 has an electrically insulating sheath 62, which is stripped off above an open end 63 of the electrical conductor 6, so that a core 61 of the electrical conductor 6 is visible.

The clamping spring 3 has a pivotable about a pivot axis 8 in a pivoting direction 81 clamping leg 32, and a holding leg 31, with which it is supported in particular during pivoting of the clamping leg 32 in a simple and secure manner on the terminal housing 12 (in particular made of plastic). A metallic clamping cage is not provided here, but is optional conceivable. Preferably, the holding leg 32 and the clamping leg 32 are connected to each other via a bend. In this bend engages an advantageous support contour of the terminal housing, which is penetrated here by the axis of rotation 8 and which also serves as a movement limit.

The clamping leg 32 has an open end 33. In the latching state R, it is locked with its open end 33 against its restoring force with the holding means 41. The retaining spring 4 is pivotable about a second pivot axis 9 in and against a second pivoting direction 91. When giving the retaining spring 4, the holding means 41 is pivoted with it against the restoring force of the retaining spring 4. As a result, the position of the holding means 41 shifts about the second pivot axis 9, so that the open end 33 of the clamping leg 32 is unlatched.

In order to pivot the retaining spring 4 in the second pivot direction 91, it has a pressure surface 42. The pressure surface 42 is provided transversely to the sliding direction S or conductor insertion direction S. By pressure on the pressure surface 42, the retaining spring 4 in the second pivoting direction 91 is pivotable.

Between the clamping spring 3 and the busbar 2, a free space is formed, in which the electrical conductor 6 in the latching state R of the clamping leg 32 in and against the sliding direction S is freely displaceable.

When moving the introduced into the spring terminal 1 electrical conductor 6 in the sliding direction S in the housing 11, the open end 63 of the electrical conductor 6 in contact with the pressure surface 42. When pushed further in the sliding direction S, he presses on the pressure surface 42. Thus, the Retaining spring 4 pivoted in the second pivot direction 91. In this case, the clamping leg 32 is unlocked by the holding means 41 and pivoted in the pivoting direction 81. The pressure surface 42 is arranged in the sliding direction S below the holding means 41, so that a free pivoting of the clamping leg 32 in and against the pivoting direction 81 is possible.

The spring clamp 1 also comprises a return means 5. The return means 5 is displaceable in and against the sliding direction S. It is provided for pivoting back the clamping leg 32 against the pivoting direction 81. In this case, the clamping leg 32 is zurückschwenkbar by moving the return means 5 against the pivoting direction S from the clamping state K in the latching state R, so that its open end 33 with the holding means 41 locked again. Then, in the spring terminal 1 previously clamped in the terminal state K electrical conductor 6 of the spring terminal 1 in the latching state R can be removed again.

In the embodiment shown here, the return means 5 is arranged in the latching state R between the clamping spring 3 and the electrical conductor 6. In the clamping state K, it is arranged in the sliding direction S above the clamping leg 32. Therefore, the return means 5 acts in clamping state K befindlichem clamping leg 32nd when moving in the sliding direction S directly on the clamping leg 32, so that the required displacement for pivoting back of the clamping leg 32 is small.

It is visible that the return means 5 protrudes in the clamping state K from a terminal housing 12 of the spring terminal 1. This makes it very easily accessible and very easily pressed in the sliding direction S. To actuate the return means, this has an actuating groove, which simplifies an actuation with a tool such as a screwdriver. In addition, the return means 5 is clamped in the clamping state K between the clamping leg 32 and the terminal housing 12 in this, so that it does not come off the terminal housing 12.

The Fig. 2 (a) shows the clamping spring 3 in the latching state R of the clamping leg 32. The electrical conductor 6 is still disposed outside of the spring terminal 1. It is visible that the open end of the clamping leg on the holding means, which is designed here as an edge, is locked. Clearly visible is also the free space 13 between busbar 2 and clamping leg 32nd

In Fig. 2 (b) the electrical conductor 6 is inserted into the spring-loaded terminal 1 and presses on the pressure surface 42 of the retaining spring 4. Visible is the displacement of the holding means 41, by which the open end 33 of the clamping leg 32 from the holding means 41 is unlocked.

The Fig. 2 (c) shows the jammed in the spring terminal 1 electrical conductor 6. The clamping leg 32 is pivoted in the pivoting direction 81 about the pivot axis 8 and its open end 33 pushes the wire 61 of the electrical conductor 6 against the busbar 2. It is also apparent that the clamping leg 32 the Return means 5 when pivoting in the pivoting direction 81 against the sliding direction S suppressed. As a result, the return means 5 shifts against the sliding direction S, so that it protrudes from the terminal housing 12 and is easily accessible. The clamping leg 32 also has an angle 321 to the sliding direction S. It is conceivable to choose this so that the return means 5 is pressed in the clamping state K against the terminal housing 12 and is clamped self-locking.

A loosening of the electrical conductor 6 is possible by the return means 5 is moved starting from this clamping state K in the sliding direction S until the open end 33 of the clamping leg 32 again locked to the holding means 41 in the latching state R.

The object of Fig. 2 - to which reference is made - is added to the Fig. 1 (A - e) advantageously supplemented by a sliding sleeve 7, which serves as an insertion aid for the conductor. This sliding sleeve 7 is particularly advantageous when a conductor 6 is used with very finely stranded wire or wire or strand arrangement 61.

The sliding sleeve 7 is guided with a sliding portion 71 slidably in the insertion opening 11 of the housing 12. Both the sliding sleeve 7 and the insertion opening 11 have in this area corresponding sliding contours, so that the sliding sleeve 7 with a sliding portion in the insertion opening 11 is well movable.

The sliding contours can according to a preferred - but not mandatory - design corresponding rectangular, eg square, cross-sections (see Fig. 1d ) but also others, such as cylindrical cross sections.

The sliding sleeve 7 also has its own passage opening 72 into which the electrical conductor 6 stripped in its end area can be inserted. This passage opening 72 tapers such that for conductors 6 of a suitable pressure gauge whose insulation (a little) is greater than the diameter of the passage opening 72 in the narrowed section, although the core arrangement 62, but not the insulation or sheath 61 in the inserted state can protrude from the sliding sleeve 7 in the sliding direction S. The sheath 61 is rather in the inserted state of the conductor on the tapered portion 73 in the sliding direction and can thus advance the sliding sleeve in the sliding direction S in the continued movement of the conductor 6 in the sliding direction S.

The sliding sleeve also has in extension of the sliding portion 71 a web-like actuating lug 74 which extends to the retaining spring 4 and which is coupled at its end directly or in the region of a transverse web 75 with the retaining spring 4. Here, this coupling is realized in that one end of the retaining spring in a slot 76 of the actuating lug 74, here the crosspiece 75, engages. The other end of the retaining spring 4 with the holding means is preferably fixed in a slot of the housing 12. The retaining spring 4 can be deflected in its sliding direction S at its end coupled to the actuating lug 74.

The function of this arrangement is as follows.

When inserting the stripped conductor end, the insulation 61 comes on the tapered portion 73 to the plant. In this state, the wire arrangement or strand arrangement 62 protrudes from the sliding sleeve 7 in the sliding direction or in the direction of the contact point to be formed. Upon further insertion of the conductor 6, the sheathing or insulation 61 pushes the sliding sleeve 7b further in the sliding direction S. As a result, coupled to the actuating projection 71 retaining spring 4 is deflected, which finally releases the clamping spring 3 with a sufficiently wide insertion of the conductor 6 with the sliding sleeve 7, so that they relax and contact the line core.

The opening of the terminal point can be analogous to Fig. 2 done with a return means 5. This opening is in Fig. 1 (e) indicated.

Preferably, the insertion opening 61 has a gradation as a stop for the sliding means in the sliding direction S in order to define the maximum sliding path.

The spring clamp 1 of Fig. 3 - 4th differ from the spring terminal 1 of Fig. 1 in particular, and among other things by the formation of the retaining spring 104. A sliding sleeve is not shown in this embodiment, but would be supplemented. Each spring terminal of the Fig. 3 - 4th can therefore be provided with a sliding sleeve, preferably according to the type Fig. 1 is designed.

Fig. 3 shows a spring terminal 101, here a nachreihbare terminal, with a bus bar 102 for contacting an electrical conductor, acting as a compression spring clamping spring 103, which is provided for clamping the electrical conductor (not shown here) in the spring terminal 101, and with a retaining spring 104th As mentioned, the sliding sleeve to be supplemented is not shown.

On the retaining spring 104, a holding means 141 is arranged, on which the clamping spring 103 is locked in a latching state R.

The busbar 102, the clamping spring 103 and the retaining spring 104 are in a terminal housing in the manner of Fig. 2 arranged, of which in Fig. 3 only one main body that is in Fig. 3 not shown, and which is preferably made of an electrically insulating material, in particular of a plastic. In the terminal housing in turn an insertion opening for insertion of the electrical conductor is provided. It is going to the appropriate remarks too Fig. 2 directed.

The clamping spring 103 has a about a pivot axis 108 in a pivoting direction 181 pivotable clamping leg 132, and a holding leg 131, with which it is supported in particular during pivoting of the clamping leg 132 in a simple and secure manner to a metallic clamping cage, here with the busbar 10 is formed in one piece. Preferably, the holding leg 131 and the clamping leg 132 are connected to each other via a bend 130. In this bend 130 engages an advantageous support contour of the terminal housing 112, which is here interspersed by the axis of rotation 108 and which also serves as a movement limit (see Fig. 2 ).

The clamping leg 132 has an open end 133. In the latching state R, it is locked with its open end 133 against its restoring force with the holding means 141.

The spring clamp 101 also comprises a return means 105. The return means 105 is displaceable in and against the sliding direction 107. It is provided for pivoting back the clamping leg 132 against the pivoting direction 181. In this case, the clamping leg 132 is zurückschwenkbar by moving the return means 105 against the pivoting direction 107 from the clamping state K in the locking state R, so that its open end 133 with the holding means 141 locked again. Then, an electrical conductor 106, which is clamped in the spring-force terminal 101 previously in the clamping state K, of the spring-force terminal 101 in the latching state R can be removed again.

In the embodiment shown here, the return means 105 is arranged in the latching state R between the clamping spring 103 and the electrical conductor. In the clamping state K, it is arranged in the sliding direction 107 above the clamping leg 132. Therefore, the return means 105 acts in clamping state K befindlichem clamping leg 132 when moving in the sliding direction 107 directly on the clamping leg 132, so that the required displacement for pivoting back of the clamping leg 132 is small.

It is again advantageous that the return means 105 protrudes in the clamping state K from a terminal housing 112 of the spring terminal 11. This makes it very easily accessible and very easily pressed in the sliding direction 107. For actuating the return means, this has an actuating groove 151, which simplifies an actuation with a tool such as a screwdriver. In addition, the return means 105 in the clamping state K between the clamping legs 132 and the The terminal housing is jammed in this, so that it does not come loose from the terminal housing.

Shown is in (a) the clamping state K of the spring terminal 101 without the inserted conductor 106. It is visible that the open end 133 of the clamping leg 103 in this embodiment of the spring terminal 101 without the inserted conductor 106 rests against a detent 121 of the bus bar 102. The bus bar 102 of this embodiment is part of a clamping cage 120, e.g. bent in U-shape.

When not inserted into the spring terminal 101 conductor 106, the return means 105 is moved in the clamping state K far by means of the clamping leg 132 against the sliding direction 107, so that it is very easily accessible from the outside.

The retaining spring 104 of Fig. 3 and 4 has a bearing leg 140. However, this bearing leg 140 extends transversely to the sliding direction 107. It is fixed or at least supported on the main body or on a part of the clamping cage or on another part. At the bearing leg 140, the pivot leg 143 connects. However, the bearing leg 140 and the pivot leg 143 here in contrast to the embodiment of Fig. 1 connected by a bow 401 and the pivot leg is approximately L-shaped. As a result, the bearing leg 140 and the pivot leg 143 at an acute angle 192 to each other and form a (in side view) U-shaped unit.

At the pivot leg 143, the pressure surface 142 connects in this embodiment as well. In addition, the holding means 141 is also arranged on the pivot leg 143, so that it is positioned in the sliding direction 107 in front of the pressure surface 142. The holding means is compared to the prior art of Fig. 1 developed particularly advantageous.

The holding means 141 is formed by a latching edge, which is arranged on a side of the pivot leg 143 integrally formed retaining wing 410. Alternatively, on both sides of the pivot leg 143, such a retaining wing 410 can be arranged in each case.

The Fig. 3 (b) shows the spring clamp 101 during pivoting of the clamping leg 132 from the clamping state K against the first pivoting direction 181 in the locking state R. It is visible that the open end 133 of the clamping means 132 thereby comes into abutment against the holding means 141 and the retaining spring 104 while in the sliding direction 107 presses. As a result, the pivot leg 143 and the pressure surface 142 are pivoted about the second pivot axis 109 in the second pivot direction 191. As a result, the retaining spring 104 deviates in the second pivoting direction 191 and the clamping leg 132 is displaceable behind the latching edge 141.

When pivoting back the pivot leg 143, the clamping leg 132 is latched behind the locking edge 141. The spring clamp 101 is then in the latching state R. This shows the Fig. 3 (c) , The pivoting of the retaining spring 104 is in the Fig. 3 (d) shown.

The geometry of this embodiment of the retaining spring 104 has a self-locking effect, so that the clamping spring 103 is held securely by the retaining means 141 of the retaining spring 104, even under strong vibration influences. Preferably, a latching edge 410 'on one or more holding wings 410 of the holding means relative to the conductor insertion direction or sliding direction 107 has an angle alpha preferably greater than 0 °, preferably greater than and less than 45 °

Fig. 4 shows a further embodiment of the retaining spring 104 with a likewise self-locking geometry. These retaining spring 104 also has an approximately L-shaped pivot leg 143 with laterally formed retaining wings 410. The bearing leg 140 extends here but transversely to the pressure surface 142 and against the sliding direction 107. The bearing leg 140 is fixed to the holding leg 131 of the clamping spring 103, for example by means of a screw or rivet 134th
