Definitions

  • the invention relates to a connecting terminal for connecting at least a first electrical conductor to a second electrical conductor.
  • the connecting terminal has a housing with a first conductor insertion opening for inserting the first electrical conductor and with a second conductor insertion opening for inserting the second electrical conductor.
  • the first and second conductor insertion openings are arranged on opposite sides of the housing.
  • the connecting terminal has a contact insert comprising a first clamping spring, a second clamping spring, and a busbar.
  • Such connecting terminals are known, e.g. from DE 10 2014 119 421 B4 . From the DE 75 11 815 U A screwless spring terminal with a housing that has two housing halves is known. EP 2 752 944 A2 An electrical terminal and a method for assembling it are known. DE 10 2018 101 381 A1 A connector with a spring contact is known. US 2010/0068925 A1 A conductor connection terminal with direct plug-in technology is known. DE 10 2016 116 510 A1 Another conductor connection terminal with direct plug-in technology is known.
  • the invention is based on the object of further improving such a connecting terminal.
  • connecting terminal having the features of claim 1.
  • the inner part which is provided as a separate component and inserted into the housing, creates a multifunctional component that can implement a multitude of different functions with minimal effort, as explained below.
  • the structure and complexity of the connecting terminal remain straightforward, as only a relatively small number of individual parts are required.
  • Such a connecting terminal can be designed, in particular, as a through terminal.
  • the spring-loaded terminal connections formed by the clamping spring and the busbar can be designed as direct plug-in connections (push-in).
  • the inner piece can fulfill certain mechanical and electrical functions, e.g., supporting the first and/or second clamping spring, or insulating functions, e.g., improving clearance and creepage distances.
  • the inner piece can, for example, perform the functions of conductor and spring guidance, as well as the function of a conductor stop, and also facilitate the assembly of the connecting terminal.
  • the inner piece be made of an insulating material, e.g., plastic.
  • the inner piece can be in contact with at least one inner wall of the housing.
  • the inner piece is configured to at least partially support and/or engage a portion of the first and/or second clamping spring in a form-fitting manner. This ensures that the contact insert is stably positioned and held in the housing.
  • the inner piece can have, at least in some areas, a contour that corresponds to part of the contour of the clamping spring, at least where the first and/or second clamping spring rests against the inner piece.
  • the contact insert can also be positioned and held in the housing alternatively or additionally via form-fitting retaining edges and/or snap-in connections.
  • the contact insert forms a self-supporting unit with the inner piece, which can be pre-assembled and inserted into the housing. This makes the assembly of the connecting terminal particularly simple and time-saving.
  • the first and the second clamping spring each have a clamping leg and an arcuate section, wherein the arcuate sections of the first and the second
  • the second clamping spring when assembled, should be arranged at a smaller distance from each other than the clamping legs. Accordingly, the curved sections of the clamping springs point toward each other. In this way, a compact through-terminal with direct plug-in connections on both sides can be created with little effort. A gap can be provided between the curved sections of the clamping springs.
  • the concave inner contour of the first clamping spring or the second clamping spring can, for example, be the inner contour of the arcuate section of the respective clamping spring. In this way, the first projection can be inserted particularly far into the first clamping spring, or the second projection can be inserted particularly far into the second clamping spring.
  • the first closure piece and/or the second closure piece each have window-like openings arranged in opposite side walls of the closure piece. This simplifies the fixing of the first closure piece or the second closure piece in the main housing part.
  • the window-like openings can For example, they can be arranged in pairs opposite each other on four side walls of the respective closure piece.
  • the side webs and the clamping leg protrude from a common root region of the first clamping spring, with the side webs being connected to each other at their ends remote from the root region via a cross web.
  • the cross web can thus serve to connect the side webs.
  • the crossbar is arranged on the side of the busbar facing away from the clamping leg.
  • the crossbar can be used as a fastening element for attaching the clamping spring to the busbar.
  • the first clamping spring has an edge at the free end of the root region.
  • the edge points in a direction that is predominantly opposite to the direction of the clamping leg.
  • the edge of the root area can rest against an inner wall of the housing, e.g., an inner wall of the main housing section. This allows the clamping spring to support itself against the inner wall of the housing when mounted and/or under tensile load, and possibly dig slightly into this inner wall. This further improves the support effect and generates an increase in the extraction forces.
  • the second clamping spring can be identical to the first clamping spring or designed differently.
  • the contact insert is designed as a direct plug-in connection for the direct insertion of the first and/or second electrical conductor.
  • a sufficiently rigid electrical conductor can be inserted directly into the terminal point, i.e., without separate actuation of the clamping leg.
  • the connecting terminal is designed without an actuating element for the first and/or second clamping spring. This facilitates a particularly compact and slim design of the connecting terminal.
  • clamping spring to be additionally supported by the inner piece in its curved section, which has the convex outer contour.

  • the side webs 48 are connected to one another at their ends remote from the root region 46 via a crossbar 45.
  • the crossbar 45 is arranged on the other side of the busbar 3 than the side bars 48 and the clamping leg 43.
  • the clamping leg 43 is arranged between two curved side bars 48 of a clamping spring.
