Definitions

  • Electrical connection terminal for connecting electrical cables to electrical medical devices
  • the invention is based on an electrical connection terminal for connecting electrical lines to electrical, medical devices, in particular pacemakers.
  • Pacemakers can be implanted in the human body or worn outside the body. It is an electric pulse generator, which is connected via electrical lines to the heart.
  • the electrical lines are usually electrodes, in particular wires.
  • the distal end of the electrical leads is inserted into the tissue of the heart to be sensed or controlled.
  • the pacemaker is equipped with terminals that secure the proximal end of the electrical leads.
  • the terminals must meet the requirement that both a secure mechanical connection and a reliable electrical coupling is guaranteed.
  • the electrical cables must not be disconnected from the terminals of the pacemaker.
  • the electrical coupling between the terminal and the electrical lead must ensure that the tiling of a current is not affected by the formation of an oxide layer on the electrical lead or on the terminal.
  • the terminal should be so flexible that it is not damaged when moving the electrical lines relative to the terminal.
  • the inventive electrical terminal with the features of claim 1 consists of a terminal housing, a contact pin with self-centering double conical collet chuck, a clamping body and a clamping sleeve, which clamps the collet with the terminal housing and the clamping body.
  • the proximal end of the electrical line is inserted into a socket of the contact pin.
  • the socket of the contact pin extends over almost its entire
  • the collet When screwing the clamping sleeve onto the terminal housing, the collet is compressed from two sides.
  • the terminal housing facing cone experiences a force from behind, while the clamping body facing cone experiences a force from the front.
  • the clamping jaws of the collet are pressed radially inwardly against the running in the socket electrical line.
  • the force with which the jaws press against the electrical line depends on how far the clamping sleeve is screwed onto the terminal housing.
  • the jaws are not only punctiform but within a relatively large range of the electrical line. As a result, a relatively secure, mechanical coupling is achieved, which precludes unintentional release of the electrical line from the terminal.
  • an electrical contact is made, which is not affected by selective oxidation.
  • a plurality of slots are provided in the contact pin in the axial direction. They extend over the first and second cone far into the region of the contact pin which is inserted into the socket of the terminal housing. Through the slots of the contact pin is divided with the collet into several jaws.

  • This cuff is in particular made of an insulating material, such as plastic. This rules out that a current flows through the user when the clamping sleeve is actuated.
  • the rough surface of the sleeve such as a corrugation, facilitates the actuation of the collet firmly connected to the sleeve.
  • the clamping sleeve is connected to the terminal housing such that they can not be completely detached from the terminal housing.
