Definitions

  • the invention relates to a contact and clamping device according to the preamble of claim 1.
  • the receiving chamber and the threaded hole are arranged one behind the other on a common axis.
  • the receiving chamber narrows axially inwardly in a funnel shape to a narrow point at which a clamping surface that widens in a funnel shape begins.
  • a threaded pin is screwed into the threaded hole, the axially outer end region of which, depending on the application, is designed as a pin contact or a socket contact, and the axially inner end region of which is a pointed cone.
  • This contact and clamping device is provided for electrical conductors in the form of strands.
  • the invention has for its object to design a contact and clamping device for electrical connectors with an axially arranged threaded pin such that it is suitable for clamping any, even solid, electrical conductor and can be equipped with any slim pin or socket contacts.
  • FIG. 1 shows a first embodiment of a contact and adhesive device according to the invention in axial section I-I according to FIG. 2, in an unused state
  • Fig. 3 is a sectional view corresponding to FIG
  • Device with clamped electrical conductor 4 shows a second exemplary embodiment of a contact and clamping device according to the invention in axial section IV-IV according to FIG. 5, in the unused state,
  • Fig. 5 shows the cross section V-V in Fig.4
  • FIG. 6 shows a section of the device corresponding to FIG. 4, with the electrical conductor clamped in place.
  • the device shown in FIGS. 1 to 3 has an elongated contact body 10 with two flat broad sides 11, a partially cylindrical narrow side 11 'and a contact extension 12, which is drawn as a contact pin, but can also be a contact socket.
  • the contact extension 12 is preferably made in one piece with the contact body 10 as a turned part from a flattened rod profile.
  • the contact extension 12 has an axis A, which is also the main axis of the entire contact body 10.
  • the broad sides 11 and narrow side 11 ′ extend parallel to this axis A.
  • Two end faces 13 of the contact body 10 extend at right angles to it.
  • a circular cylindrical receptacle 14 with the axis B and a bore 16 of somewhat smaller diameter with the axis C are incorporated.
  • the axes B and C are arranged on each side of the axis A, parallel to it and lying with it in a common central plane D, with respect to which the contact body 10 according to FIGS. 1 to 3 is completely symmetrical.
  • an auxiliary chamber 18 is machined, for example milled, into the contact body 10, which connects the bore 16 to the receiving chamber 14. Axially outside, in FIGS.
  • the bore 16 is designed as a threaded hole 20, while its axially inner end forms a conical socket 22.
  • a clamping body 24 in the form of a flat stamped part is arranged in the secondary chamber 18.
  • the clamping body 24 has an arcuate ramp 26, which faces the threaded hole 20, and a foot 28 facing away from the threaded hole.
  • the foot 28 is semicircular and lies in the socket 22, so that the clamping body 24 about an axis C of the Bore 16 intersecting axis E normal to the center plane D is pivotable.
  • the ramp 26 forms a circular arc section of larger radius, the center of which lies in the axially inner region of the receiving chamber 14.
  • a threaded pin 30 is screwed into the threaded hole 20, which has a frustoconical pressure surface 32 at its axially inner end and, in the unused state of the contact and clamping device according to FIG. 1, only projects into the secondary chamber 18 to such an extent that the clamping body 24 is prevented to swing out of it.
  • a return spring 34 is arranged in the receiving chamber 14 in the form of an angled leaf spring, which has a foot 36 clamped in the axially inner end region of the receiving chamber 14 and a free spring leg 38.
  • the spring leg 38 is arranged in the rest state in an overlap region of the receiving chamber 14 and the secondary chamber 18 and supports the clamping body 24 in such a way that it cannot swing into the receiving chamber 14 unintentionally.
  • the contact and clamping device shown in FIGS. 1 to 3 includes a housing 42 made of insulating material, which can be of a known type. For the sake of completeness, such a housing 42 is shown in connection with the exemplary embodiment of a contact and clamping device shown in FIGS.
  • the housing 42 has parallel side walls 44, end and intermediate walls 46 arranged at right angles thereto and a housing base 48.
  • the housing 42 is divided into individual chambers by the intermediate walls 46, into each of which a contact body 10 in the direction the axes A, B and C can be inserted.
  • the contact body 10 according to FIGS. 4 to 6 differs from that shown in FIGS. 1 to 3 essentially in that the secondary chamber 18 is open not only to one of the narrow sides 11 'but also to one of the broad sides 11.
  • the secondary chamber 18 is incorporated, for example, with a C-shaped milling cutter. It is particularly advantageous if the secondary chamber 18 does not extend from one broad side 11 to the opposite but the opposite broad side 11 is preserved as an intact, albeit very thin side wall, so that the contact body 10 does not bend due to the reaction forces occurring when the threaded pin 30 is tightened becomes.
  • the contact body 10 has a base 50 between the secondary chamber 18 and the housing base 48.
  • the narrow side 11 'of the contact body 10, towards which the secondary chamber 18 is open, has a longitudinal groove 52.
  • the clamping body 24 is again a stamped part made of sheet metal, which, in contrast to the exemplary embodiment shown in FIGS and 56 are formed.
  • the ramp 26 is formed on the upper leg 54 of the clamping body 54 in FIGS. 4 and 6, which cooperates with the conical pressure surface 32 of the threaded pin 30.
  • a head 58 of the return spring 34 is clamped between the two legs 54 and 56.
  • a clamping body 24 together with a return spring 34 attached to it is first inserted into the secondary chamber 18 of each contact body 10 and thereby temporarily hold that the pressure surface 32 of the threaded pin 30 slightly increases the ramp 26 touches and also the foot 36 of the return spring 34 engages around the base 50 of the contact body 10 like a clamp. Subsequently, the contact body 10 is pushed into one of the chambers of the housing 42, whereby it pushes out a pair of lugs 60, which are formed on the inside on the side walls 44 of the housing 42 and, after the contact body has been completely inserted, engage behind its free end face 13.
  • the contact body 10 is enclosed by the housing 42 in such a way that the clamping body 24 cannot fall out of the secondary chamber 18 even if the setscrew 30 is accidentally unscrewed too far or the clamping action of the foot 36 of the return spring 34 should be low.

Abstract

Un élément de contact (10) comporte une chambre de réception (14) pour la section terminale (40) d'un conducteur électrique, ainsi d'un trou taraudé (20) dans lequel est vissée une vis sans tête (30) qui peut être serrée de manière à ce que l'extrémité terminale (40) du conducteur électrique soit pincée dans la chambre de réception (14). L'élément de contact (10) comprend sur le côté de la chambre de réception (14), une chambre latérale (18) reliée à la précédente. Cette chambre latérale (18) comprend un élément de pincement (240 qui comporte une déclivité (26). Le trou taraudé (20) débouche dans la chambre latérale (18) et la vis sans tête (30) comporte une surface de pression qui appuie sur la rampe (26) de l'élément de pincement (24) et enfonce ce dernier dans la chambre de réception (14) au moment où la vis sans tête (30) est serrée.
