Definitions

  • Connectors of the above type are widely known. These connectors are usually made of two components, namely a contact inner part and a spring element, wherein the spring element is designed as a so-called over-spring, which is the inner contact part at least partially encloses.
  • the electrical plug-in connector is plugged onto a so-called knife, with the inner contact part coming into contact with the knife.
  • the inner contact part itself is divided into several areas, namely a fastening part, to which a stripped end of an electrical connector is preferably crimped.
  • the inner contact part has a central portion, which is preferably formed like a waist, at the waist of a fastener is provided, which is designed for fixing the inner contact part and a contact portion with a contact part, which makes electrical contact with the opposite knife.
  • the contact parts are usually designed as contact blades.
  • a contact inner part has two or more opposing fins which are arranged at a distance which is smaller than the thickness of the knife. By inserting the knife, the contact blades are forced to spring. As a result, a corresponding deformation occurs, which achieves a defined normal force at the contact blades and the blade brought about contact point.
  • contact blades There are also different embodiments of the configuration of the contact blades known. On the one hand, it is provided to form contact lamellae exposed, so that they can spring open when plugged onto a knife. Another embodiment shows a bracket which clasps the contact blades, wherein the bracket is supported on the over-spring. Furthermore, an embodiment is known in which the contact blades are welded to the over-spring.
  • an electrical connector which consists as a socket contact of a contact inner part and an over-spring which surrounds the contact inner part partially.
  • the contact inner part consists of an attachment portion for an electrical line, from a central portion and at its free end of a contact portion having a plurality of contact blades which are anchored on one side to the central portion.
  • the free ends of the contact blades which are bent in an arc outward to facilitate the introduction of so-called knives of a mating connector, lie with a bias on the inside of the over-spring.
  • the insertion force is low by the initially still auspeakunpcityen free ends of the contact blades, so that the correct positioning of the connector can be detected on the mating connector.
  • an electrical connector 1 which consists essentially of two components, namely a contact inner part 2 and an over-spring 3, wherein the over-spring 3 at least partially surrounds a part of the inner contact part 2.
  • the contact inner part 2 is divided into preferably three areas, namely a first area in the form of a fastening part 4, a middle section 5 and a contact section 6. In the area of the contact section 6, the over-spring 3 preferably also extends.
  • the contact section 6 has three or more contact blades 7. In the embodiment shown in Figures 1 and 2, four contact blades are provided which differ from The middle section 5 extend freely away and between the individual contact blades 7 each have a free space 8 is provided.
  • the contact blades 7 have a contact region 9, which serves to enter into an electrical connection with a knife not shown in the drawings.
  • the contact region 9 of the respective contact blades 7 is designed such that a contact point 10 is formed between the blade, not shown here, and the respective contact blade 7.
  • the over-spring 3 In the assembled state, the over-spring 3 is arranged in the contact portion 6 such that it is held in the region of the central portion 5 via fixing elements 11.
  • the spatial dimension of the over-spring 3 is designed such that in the unassembled state, the contact blades 7 can move freely within the over-spring 3.
  • the insertion process of the electrical connector 1 according to the invention is as follows:
  • the contact blades 7 When a knife is inserted into the electrical connector 1, the contact blades 7 widen in such a way, at most up to the position up to which they rest against the inside of the over-spring 3. When obliquely plugging the electrical connector 1 on a knife, it is possible that individual contact blades 7 dodge, so that a wide opening for receiving the blade is generated. Due to the concern of the contact blades 7 on the overspring 3 further expansion of the contact blade spacing, the free ends of the contact blades 7 in the direction of the inlet opening for the knife to deform under deformation of the contact blades 7, which is possible only with increased effort, before it on the boundary elements of the inlet opening accumulate the over-spring 3, which stop any further deformation. This construction has the consequence that the insertion force increases suddenly.
