Definitions

  • the invention relates to a blind plug or isolating plug for covering or separating switching contacts in LSA-PLUS connection strips of telecommunications equipment.
  • connection system - LSA PLUS system for short - according to which the thin wires of telephone cables can be connected without soldering, screwing and stripping to specially designed contact elements, for example terminal strips.
  • These contact elements have at least two upright spring tongues, which delimit a slot into which the respective wire is pressed transversely.
  • the spring tongues and the slot are dimensioned such that when the wire is pushed in, the sharp side edges of the spring tongues cut the insulation and at the same time these side edges penetrate slightly into the conductor material of the wire.
  • the object of the invention is to develop a blind plug or isolating plug of the type mentioned at the beginning, with which the contact points of the contact elements can be covered in a space-saving and reliable manner or can be separated in a contactless manner while avoiding contamination by plastic abrasion.
  • this object is achieved in that a widened central support part connects to an upper pulling head of the plug, on the underside of which two spring tongues with latching lugs and a central guide web are arranged between them, and that the plug can be inserted into the LSA-PLUS terminal strip and therein can be locked with the locking lugs.
  • a plurality of centering projections are preferably integrally formed in the central support part.
  • extensions for separating switching contacts in the terminal block are advantageously provided on the spring tongues below the latching lugs.
  • the spring tongues with their locking lugs are designed in such a way that when the blind or isolating plug is inserted into the corresponding opening of the connection strip, they provide a space-saving and reliable cover for the switching contacts by snapping the locking lugs behind shoulders in the connection strip and, in the case of the disconnecting plug, simultaneously open the switching contacts without touching the contact points on the spring tabs of the switch contacts.
  • a secure, non-slip fit of the plug in the terminal block is ensured in the embodiment of the invention by the centering projections formed on the middle support part, which engage in the recesses provided in the terminal strips when the plug is pressed in.
  • the isolating plug 1 shown in FIGS. 1 to 3 consists of a one-piece plastic part and has a central widened support part 2, on which an upper pulling head 4 and at the bottom two spring tongues 5 with outwardly facing locking lugs 6 and a central guide web 3 are formed in between .
  • the locking lugs 6 each have a lateral inclined ramp 6a and a lower extension 6b, which serves to separate normally closed contacts in the terminal block.
  • two centering shoulders 8 with inclined surfaces are formed on both sides of the lower surface of the central support part 2. Furthermore, a through hole 7 is provided in the pulling head 4, into which a suitably designed tool can be inserted to pull out the isolating plug.
  • the spring tongues 5 When inserting the isolating plug into a corresponding opening in a terminal block (not shown), the spring tongues 5 are pushed out laterally due to the catches 6 formed inclined ramps 6a bent back. As soon as the isolating plug 1 has reached its final covering position, the two tongues 5 spring back and the latching lugs 6 engage behind corresponding recesses in the terminal strip. At the same time, the centering lugs 8 also engage in corresponding notches or recesses in the terminal block.
  • the contact points of the contact elements or the normally closed contacts are separated by the extensions 6b of the detents 6, but plastic abrasion from these parts of the isolating plug 1 at the contact points of the contact elements is avoided and these remain clean.
