Definitions

  • the present invention relates to a screwless electrical clamp.
  • the object of the invention is to provide a clamp of the type mentioned, which is technically simple, takes up relatively little space and can be produced inexpensively.
  • the screwless electrical terminal 10 shown in FIGS. 1 to 4 has an essentially approximately V-shaped leaf spring piece 11 with a first and a second V-leg 11a or 11b, each of which extends in a straight line and in the V-apex through a apex portion 11c running in a circular arc are connected to one another.
  • End parts 11d and 11e of the two V-legs facing away from the apex part 11c are angled towards one another and arranged and designed such that they overlap.
  • the angled end portions 11d and 11e are each provided with a first and a second circular opening 12 and 13, respectively.
  • the V-legs 11a and 11b enclose an angle between them in the range from 110 ° to 140 °, preferably from 130 °, and the two openings 12 and 13 have positions offset with respect to one another, as clearly shown in FIG Fig. 1 can be seen.
  • the openings 12 and 13 can be brought into register with one another.
  • the angled end portions 11d and 11e each have an approximately circular arc shape, at least in part gene course around the axis of curvature 14 of the apex 11c.
  • the leaf spring piece 11 is made of electrically conductive material, for example stainless steel or spring bronze.
  • One (11a) of the V-legs 11a and 11b is e.g. attached to an electrically conductive support and contact piece 16 by means of welding points 15 or by rivets (not shown).
  • the latter has an angled tab 16a, which runs approximately parallel to the angled end portion 11d on the support and contact piece 16 V-leg 11a.
  • the tab 16a of the support and contact piece 16 has a third opening 18, which is congruent with the opening 12 of the end part 11d of the V-leg 11a attached to the support and contact piece 16.
  • the leaf spring piece 11 Under the influence of its own bending elasticity, the leaf spring piece 11 then tries to relax to return, wherein the conductor 20 is pressed by means of the lower peripheral part of the opening 13 in FIG. 4 against the upper peripheral parts of the stationary openings 12 and 18 and thus clamped. It can be seen that the conductor 20 is now held by three edges and is secured against being pulled out of the terminal.
  • the clamp 10 described is suitable e.g. as a connection terminal on an electrical device.
  • Fig. 5 it is shown how a pair of clamps 10 and 10 'of the embodiment described can be arranged with a common support and contact piece 16 which, in addition to the angled tab 16a already mentioned, has a second angled tab 16b which is part of the second clamp 10 'with a leaf spring piece 11'.
  • one terminal 10 (on the right in FIG. 5) is designed to insert the conductors to be connected in a horizontal direction
  • the second terminal 10 'in FIG. 5 has a position rotated by 90 °, so that the conductors to be connected to it are to be inserted in the vertical direction from above.
  • the two terminals 10 and 10 ' have completely identical structural designs and correspondingly the same modes of operation.
  • the housing 21 has a first funnel-shaped opening 24 for the horizontal insertion of conductors into the clamp 10 and a second likewise funnel-shaped opening 25 for the vertical insertion of conductors into the clamp 10 '. Furthermore, the housing 21 is provided with an opening 26, which allows an impact tool (not shown), e.g. a screwdriver to urge the V-legs of the leaf spring piece of the first clamp 10 against each other from above. Finally, there is a further opening 27 on the housing 21, which allows a rod-shaped tool, e.g. a screwdriver to urge the V-legs of the leaf spring piece of the second clamp 10 'against each other in an approximately horizontal direction. The whole serves as a conductor connector, which enables two or more electrical conductors to be connected to one another.
  • FIGS. 6 and 7 show that, in addition to the housing 21 described, a second housing 21 ′ of the same design can be arranged in parallel and connected to the first housing 21 by a web 28.
  • the web 28 has a through bore 29 which serves for the passage of a fastening screw (not shown) by means of which the two housings 21 and 21' are placed on a suitable base can be moored.
  • the clamps 10 and 10 'described have the advantage of being structurally simple and less prone to malfunction, taking up relatively little space and being able to be produced inexpensively. They are particularly suitable for connecting or connecting electrical signal and control lines.
  • the second exemplary embodiment of the screwless electrical terminal 10 ′′ shown in FIGS. 8 to 11 differs from the example according to FIGS. 1 to 4 as follows:
  • the first and the second opening 12 'and 13' of the two end parts 11d and 11e of the leaf spring piece 11 which are angled relative to one another are each rectangular.
  • the third opening 18 'of the angled leg 16a of the support and contact piece 16 has a rectangular shape which largely coincides with the opening 12' of the V-leg 11a leaf spring piece 11 fastened to the support and contact piece 16.
  • the third opening 18 ' is formed by punching out and angling a tongue 16b which protrudes through the two openings 12' and 13 'of the leaf spring piece 11, as can be seen most clearly in FIG. 8.
  • This tongue 16b is located at the edge of the opening 12 'which is more distant from the fixed V-leg 11a and forms a contact surface for the electrical conductor 20 to be connected, as shown in FIG. 11.
  • FIGS. 8 to 11 The use of the clamp 10 "according to FIGS. 8 to 11 is the same as that of the first exemplary embodiment. However, from FIG. 11 it can be seen that the connected electrical conductor 20 under the influence of the elasticity of the unloaded leaf spring piece 11 by means of the lower edge of the opening 13 'of the movable V-leg 11b is pressed against the tongue 16b of the support and contact piece 16. This results in a larger contact area between the lead ter 20 and the support and contact piece 16 than in the first embodiment, which allows the use of this terminal 10 "for higher currents.
  • the leaf spring piece 11 is expediently pretensioned in such a way that in the idle state according to FIG. if no electrical conductor is connected yet, the lower edge of the opening 13 'of the movable V-leg 11b is pressed against the tongue 16b with a prestressing force.
  • This measure results in a sufficiently high contact pressure when connecting thin conductors and strands, the cross section of which is formed flat when pinched.
  • the pretensioning of the leaf spring piece 11 also ensures that the connected conductor 20 is sufficiently secured against being pulled out of the clamp 10 "solely by means of the lower edge of the opening 13 'of the movable V-leg 11b in FIG. 11.
  • a pair of terminals 10 "of the second embodiment described with reference to FIGS. 8 to 11 may have a common contact piece 16, as shown for example in FIG. 5.
