Definitions

  • the present invention relates to a terminal connecting member for connecting an electric power supply to a pipe welding clamp.
  • Such welding clamps are placed over plastic pipes or plastic pipe connections. They have on their inside welding devices, such as welding wires, which provides in the supply of electric current for a tight weld the clamp with the pipe section on which the clamp sits.
  • welding can simply serve to connect two pipes, but it is also possible to supply a continuous plastic pipe in a simple manner with a tightly inserted branch by placing a weld, which has an additional pipe outlet.
  • connection connecting elements are in the prior art simply pin or socket members having a single diameter.
  • the problem now is that different electrical power supplies may also have different terminals at the cable ends, i. with different diameters. Furthermore, standardization efforts ensure that such diameters change.
  • connection element with longitudinal sections of different diameters is made GB-A-2 282 102 known.
  • connection element according to claim 1.
  • the subclaims describe preferred embodiments of the present invention.
  • terminal connection element has longitudinal sections of different diameters for engagement with counterparts of different dimensions. This creates the possibility to allow the connection of electrical power supply devices having interfaces of different sizes with a single connecting element.
  • the engagement for making contact takes place respectively at the longitudinal portion, which has the appropriate diameter; it is no longer necessary to have adapters ready.
  • the terminal connector according to the present invention is characterized in that the different diameters are 4 mm and 4.7 mm.
  • the connecting element may be a pin, so a pin-like connection point. If this is the case, it is possible to design the pin to have a small diameter upper end portion and a larger diameter lower base portion. The counterpart of the pin, if it has a larger diameter, will be firmly seated on the lower base portion, if it has a small diameter, on the upper end portion. In order to ensure a secure hold even when using the end portion with the smaller diameter, according to the invention is also possible to design the upper end portion longer than the lower base portion, in particular more than one and a half times, preferably more than twice as long.
  • connection element can also be provided in the reverse configuration to the pin, namely as a connection socket. If so, it is recommended in a preferred embodiment, the socket with an upper end portion with a larger diameter and with a lower base portion with a smaller diameter to design.
  • connection pin 1 which can sit on a welding clamp to supply them with electrical energy.
  • the terminal pin 1 is surrounded by a protective sheath 4, which is usually made of the same material (e.g., PE 100) as the welding collar, but otherwise may be made of a flexible plastic or rubber.
  • the connection pin 1 has two longitudinal sections, namely an upper end section 2 and a lower base section 3. These two sections 2, 3 can each serve to establish an electrical contact, for example by a contact bushing being pushed over at the end of a cable coming from an electrical power supply unit comes.
  • the longitudinal portions 2, 3 of the pin 1 have different diameters, the base portion 3 has the larger diameter D2 4.7 mm, and the upper end portion has the diameter D1: 4 mm.
  • connection sockets Two different types can now be plugged onto the pin 1. For example, if the female terminal has the larger inner diameter D2, it is pushed over the upper end portion 2 onto the lower base portion 4 and engaged there to make the electrical connection. If the terminal has the smaller inner diameter D1, it can be fitted on the upper end portion 2 to make the engagement and the contact there.
  • the end portion 2 is designed to be longer than the base portion 3, so that despite the smaller diameter, a sufficiently secure grip can be ensured.
