Definitions

  • the invention relates to a connector for locking electrical contacting of devices provided with round pin plugs with a circular plug-in sleeve which can be connected to an electrical cable and has at least partially designed as latching hooks contact surfaces and a round pin plug which can be locked with a corresponding latching recess.
  • a lockable plug connection for receiving a round pin plug is known, for example, from European laid-open specification 0 149 466.
  • This known plug connection is part of an electrical connection device in which the round pin plug is inserted into a metal sleeve arranged in a housing and locked there by means of latching hooks.
  • the metal sleeve serving to receive the round pin connector is in turn positively connected to the housing, which is preferably made of plastic, via latching elements.
  • a disadvantage of this known connection technology is that the metal sleeve for receiving the round pin connector is always arranged in a housing surrounding this sleeve. An application of this known connector is therefore forbidden wherever there is no space for an additional housing on the one hand and on the other hand the round pin connector is to be connected to an electrical cable.
  • a connector is known from DE-GM 68 13 698, in which locking hooks are formed in the side walls in the receiving space.
  • this connector which can be used to accommodate flat plugs, is not suitable for contacting round-pin plugs and has on the other hand, there are no special contact surfaces for engaging a round pin connector.
  • the invention has for its object to improve a connector of the type mentioned in such a way that a safe, space-saving and simple connection to an electrical cable is made possible.
  • the lockable circular socket has a receiving space for the round pin connector, which consists of a base plate with two side walls, the two free edges of which are angled inward above the base plate, with free edges forming on the contact surfaces Locking hooks pointing inwards into the receiving space are formed, which snap into a circumferential locking groove on the round pin connector.
  • the design of the connector as a circular connector that can be connected to a cable ensures that the sleeve receiving the round pin connector does not require a separate housing surrounding the sleeve, so that this connector is particularly space-saving.
  • the locking between the round pin plug and the round plug sleeve takes place via locking hooks formed on the round plug sleeve, which cooperate with the round pin plug to achieve a secure cohesion.
  • the round plug-in sleeve can be connected to an electrical cable in a simple manner via various connection options, such as, for example, a crimp connection or insulation displacement connection.
  • Such a circular plug-in sleeve is characterized in that only a small force is required for the plugging together, but on the other hand, due to the spring force of the latching hooks, a connection between the round-pin plug and the circular plug-in sleeve which is secure against vibrations and tearing forces is ensured.
  • the ends of the free edges facing away from the insertion opening for the round pin plug are cut free and angled downward, pointing into the receiving space.
  • Such a design of the locking hooks has the advantage that they are formed by simple stamping and bending processes in the manufacture of the circular plug-in sleeve can.
  • the locking hooks arranged at the ends of the free edges have a high spring force, which in turn ensures that the connecting parts are securely locked together.
  • the connector shown in the drawings consists of a circular socket 1, which can be connected, for example, via a crimp connection 2 to an electrical cable 3.
  • the circular plug-in sleeve 1 is produced from a flat sheet metal strip by punching, bending and embossing in order to obtain a circular plug-in sleeve 1 as shown in FIGS. 1 and 2a to 2c.
  • the lockable circular socket 1 has a base plate 4 with two side walls 5, the two free edges 6 of which are bent inwards in order to form a receiving space for a round pin connector 7.
  • the base plate 4 has an outward-facing indentation 8 in the middle in order to make the central region of the receiving space for the round pin connector 7 essentially circular.
  • This circular configuration of the receiving space is complemented by the fact that the mutually facing end faces of the free edges 6 are slightly bent upwards.
  • the receiving space of the round plug-in sleeve 1 designed in this way forms at least four contact surfaces 9, against which the round pin plug 7 bears on the inside of the round plug-in sleeve 1.
  • These contact surfaces 9 are, as can be seen from FIG. 1, formed on the two free edges 6 and the side walls of the embossing 8 in the base plate 4.
  • latching hooks 10 are formed on the circular plug-in sleeve 1, which engage in a circumferential locking groove 11 of the round-pin plug 7 in the assembled state.
  • the latching hooks 10 in the illustrated embodiment of a circular plug-in sleeve 1 are formed on the free edges 6 of the circular plug-in sleeve 1 serving as contact surfaces 9 by cutting free and bending.
  • the acting like barbs, engaging in the locking groove 11 of the round pin connector 7 locking hook 10 prevent involuntary loosening of the connector due to vibrations or pull-out forces, since the locking hook 10 pointing in the insertion direction prevent disconnection of the connector.
  • a plug-in connection designed in this way ensures a safe and permanent contact between the round plug-in socket 1 and the inserted round-pin plug 7 in a simple manner surrounding housing, which is why this embodiment is particularly space-saving and easy to manufacture.
