Definitions

  • the invention relates to a contact device in electrical installation devices for pluggable connection with pin or tongue-shaped connecting lugs, which in turn can each be inserted into a pocket-shaped clamping piece of the installation devices and can be contacted there in a resilient manner.
  • Such a contact device is known from EP 0 467 171 A2.
  • contact elements resilient to one another are arranged within the installation devices in the manner of clamping jaws and comprise connection lugs on both sides of an associated busbar.
  • the electrical contact to the connection lugs is established via the material elasticity of the contact elements.
  • the invention has for its object to improve a plug-in contact device of the type mentioned at the outset in such a way that a secure connection between the terminal lugs of a busbar and the associated clamping piece of the installation devices is permanently ensured with low contact resistance.
  • the invention has the advantage that the contact device can be very small and can therefore be arranged in the base of the device below the existing screw terminal and connected to it. As a result, both the screw connection from the side, which is usually customary in installation devices, and plug-in contacting from the underside of the device are possible independently of one another.
  • SPARE BLADE (RULE 26) Furthermore, large dimensional tolerances can be bridged and uniform contact forces can be achieved with a plurality of contacting points in accordance with the number of turns of the spring body. On the other hand, due to the rotatable arrangement of the spring body, the insertion forces for the terminal lugs are relatively low.
  • the contact device which is only shown schematically, is arranged in the housing base of an installation device (not shown) and has a clamping piece 1, which is connected in one piece to a screw terminal 2.
  • the latter consists, in a manner known per se, of a terminal box 2.1 which can be clamped against a pressure piece 2.3 by means of a screw 2.2.
  • wire-shaped electrical conductors can be connected to the installation device from the side in a conventional manner in accordance with the drawn arrow 2.4.
  • the clamping piece 1 which is preferably formed directly as an extension of the pressure piece 2.3, is provided with a frame part 1.1, which is shaped like a pocket and accommodates a spring body 3.
  • this is a commercially available cylindrical compression spring, the axial direction of which is perpendicular to the plane of the drawing.
  • the turns of the spring body which is only secured against falling out by a schematically indicated housing contour 4, lie relatively close to one another.
  • the spring body 3 can be supported on a contact surface 1.2 together with the angled portion 1.2 'in such a way that a gap remains with an opposite contact surface 1.3, the width of which depends in a manner to be described in more detail on the dimensions of a connecting lug 5.1 projecting from a busbar 5.
  • pin-shaped or tongue-shaped connecting lugs 5.1 are arranged several times in series on standard busbars one behind the other in the pitch of the installation devices and are used in general for the electrical connection of
  • the busbar is used here for the plug connection with the contact device through a housing opening 4.1 on the underside of the device. Above this opening, the gap between the contact surface 1.3 and the outer surface of the spring body 3 is so undersized to the thickness of the terminal lug 5.1 that after insertion of a terminal lug in the direction of arrow 5.2, the associated cylindrical spring body is radially loaded and to deformed into an oval. The individual turns of the spring body 3 lie closely against the terminal lug and press it against the contact surface 1.3. At the same time, this spring force is also transmitted to the contact surface 1.2, which is conductively connected to the clamping piece 1 via the frame part 1.1. Therefore, if the spring body 3 is made of material with good electrical conductivity, the current conduction is still improved.
  • the spring body 3 Due to the large radial deformability of the spring body 3, considerable tolerances can be bridged with an almost constant contact force, which occur on the one hand due to the manufacturing process on the installation device, but in particular may have their cause in the busbar 5 as a supplier part from different manufacturers. Furthermore, the contact force can be adapted in a wide range to the technical requirements via the diameter of the spring body 3 and the wire used for its production. On the other hand, the insertion forces for the terminal lug 5.1 are relatively low, since the spring body 3 can perform a rolling movement about its longitudinal axis with minimal friction during the insertion process within the frame part 1.1.
  • the length of the spring body is adapted depending on the depth of the frame part 1.1 and with sufficient reserve to the width of the usual connecting lugs, the end windings expediently resting on the frame part with a slight prestress.
  • the cylindrical spring body could not be made of wire, but also of flat spring band, for example in the form of an adapter sleeve, without leaving the scope of the invention.

Abstract

L'invention a pour objet un dispositif de contact destiné à des appareils d'installation électriques. Un tel dispositif est utilisé pour une connexion enfichable au moyen de cosses en forme de broches ou de languettes (5.1) qui, de leur côté, sont insérables élastiquement dans une pièce de serrage en forme de poche (1) prévue sur lesdits appareils, en vue d'y assurer le contact. L'invention a pour but de garantir dans un tel dispositif, en permanence et avec une faible impédance de transfert, une connexion sûre entre les cosses (5.1) d'une barre bus (5) et la pièce de serrage correspondante (1). Ce but est atteint grâce au fait qu'un corps élastique cylindrique creux (3) est disposé dans la pièce de serrage (1), ce corps permettant d'établir, sur sa périphérie, une force de contact entre chacune des cosses (5.1) et une surface de contact (1.3) de la pièce de serrage (1). Le corps élastique (3) a de préférence la forme d'un ressort de compression dont les spires sont relativement serrées et sollicitées radialement. Le dispositif de contact est utilisé en particulier pour la connexion électrique de disjoncteurs et autres appareils montés en série sur des barres bus enfichables de type commercial.
