Definitions

  • the invention relates to a connector unit with an insulating body and contact elements and a manufacturing method for the insulating body.
  • Connectors that have two mutually complementary connector units are used to connect electrical lines.
  • the connector units normally include a large number of contact elements, such as contact pins or contact sockets, which are held by an insulating body and insulated from one another and can be connected to electrical lines by screwed connections or crimp connections.
  • contact elements of connector units usually include a connecting part, such as a crimping part, which can be connected to an electrical line, a contact part, such as a pin or a socket sleeve, which can be connected to a corresponding contact element of another connector unit, and a holding part, which can be connected between the connection part and the contact part is arranged and which serves to anchor the contact element in the insulating body of the connector unit.
  • a ring-shaped holding part is disclosed which encloses the contact element.
  • the US2007178741A1 discloses a female connector having a contact member having a retaining portion in the form of an annular groove.
  • the contact element is held in an insertion space of an insulating body and abuts a U-shaped stop arc at the front and is held by a lever-shaped latching element which engages in the annular groove with a latching block.
  • the annular groove has an undercut on the latching side, which leads to an annular There is a locking edge that acts on the locking block and prevents the locking block from recoiling if a pulling force is applied to the connected cable.
  • the solution described is therefore intended for specially designed contact elements.
  • the DE102014112991A1 discloses a circular connector with a metal housing, into which a cylindrical insulating body can be inserted, in which contact elements are arranged, the insulating body having a laterally arranged locking means on the outer circumference for the lateral insertion or latching of a protective conductor contact element, which after the insertion of the insulating body into the metal housing has an am Metal housing formed, penetrates a receiving opening having contacting means with a contact element section. Locking means are thus provided on the insulating body and the metal housing with the receiving opening for securely holding the protective conductor contact element.
  • the present invention is therefore based on the object of creating an improved connector unit with an insulating body and contact elements and a manufacturing method for this insulating body.
  • the insulating body of the connector unit is intended to keep a large number of contact units isolated from one another and secure.
  • the contact units should also be held securely when forces are exerted on the connected lines or when the holding parts of the contact units have no special shape, eg no undercut. It should therefore be possible to use any desired contact elements, plug-in contacts or contact sockets, which have a holding part.
  • the holding part should be realizable in various configurations.
  • the contact blocks should be kept free of play, so that the contact blocks cannot automatically shift into a position in which the contact blocks may loosen more easily when force is applied.
  • At least one additional contact element e.g.
  • the connector unit a plug or a socket, comprises an insulating body, which has receiving channels running from an input part to an output part of the insulating body, in each of which a contact element, a plug contact or a socket contact, is arranged, which contact element is a contact part facing the output part has the input part facing connection part and provided between the contact part and the connection part holding part, which is held within the associated receiving channel by a latching lever which is integrally formed on the insulating body.
  • the resilient locking lever is inclined relative to the longitudinal axis of the receiving channel and protrudes into the receiving channel, which is widened by a tool channel that extends axially from a front side of the locking lever facing the output part in the direction of the Starting part runs outwards to the end of the receiving channel.
  • mold cores or molds that correspond to one another are arranged within the injection mold for each receiving channel and enclose the injected plastic material, which is injected to form the insulating body that is provided with at least one locking lever, with a mold or mold part being provided that pushed adjacent to the front side of the locking lever to be formed in a tool channel adjoining the receiving channel and pulled out of the tool channel after the injection molding process of the insulating body with the axial withdrawal of the mold cores or molds.
  • the tool channel by means of which the receiving channel is widened on one side according to the cross section of the locking lever and which remains in it after the production of the insulating body, thus allows the locking lever to be designed advantageously.
  • the receiving channel and the associated tool channel preferably run axially parallel to one another.
  • the molds can therefore be shifted axially parallel to one another.
  • Each receiving channel, in which a locking lever is to be formed is preferably formed in a rotationally symmetrical manner and expanded on one side by the associated tool channel.
  • the width of the tool channel preferably corresponds to the width of the locking lever. The properties of the receiving channel are not affected by the tool channel, so that contact elements inserted into the receiving channel continue to be held securely.
  • the locking lever protrudes resiliently into the receiving channel and is inclined to the axis of the receiving channel.
  • the locking lever thus develops a relatively powerful lever effect and allows a contact element, a plug contact or a socket contact, inserted into the receiving channel, to be held securely and without play in position.
  • a tensile force acts on the contact elements via connected lines, this is transferred to the locking lever.
  • This force causes the latching levers to be pulled against the contact element and wedge themselves accordingly on the contact element.
  • the head of the latching lever is preferably designed in the shape of a wedge, so that the remote edge rests against the holding part. This wedge shape can be realized without additional effort if the molds are configured appropriately.
  • the detent levers can therefore only be released with a tool which is inserted into the receiving channels from the input side or the line side in order to detach the detent levers from the contact elements.
  • a special design of the contact elements e.g. an undercut on the holding part, e.g is pulled against the contact element and not pushed away.
  • the contact element is held on the one hand by the latching lever and on the front by a stop part which is provided on the output side or plug side on the receiving channel.
  • the stop part is preferably a ring segment which partially delimits an outlet opening of the receiving channel.
  • the width of the missing segment, typically a segment of a circle, of the stop part therefore preferably corresponds approximately to the width of the tool channel and thus also preferably approximately to the width of the locking lever.
  • the stop part and the locking lever are therefore arranged on opposite sides of the receiving channel, which is why it is particularly important for the contact element to be held securely by the locking lever in order to keep it in an axial alignment without play.
  • Each of the contact elements is therefore held in a stable manner between the locking lever and the stop part arranged on the front side in the receiving channel.
  • the locking lever is thus aligned against the stop part arranged on the front side and protrudes at an angle into the receiving channel.
  • the angle of inclination can be selected almost arbitrarily in a range of less than 90°, since the locking lever is pushed forward and turned sideways when the contact element is inserted.
  • An inclination angle in the range of 10° to 45°, preferably 15° to 25° is preferred.
  • the molding tool or molding tool part introduced into the tool channel is therefore correspondingly wedge-shaped.
  • the connector unit a plug or a socket, which is preferably provided with latching levers in the manner described above, has an additional contact element, an additional plug contact or an additional socket contact, e.g. a protective conductor contact element, which can be inserted into the insulating body of the connector unit .
  • Additional contact elements configured as required can be used, which have a crimp element or a screw connection with a clamping screw for connection to an electrical line.
  • the additional contact element includes an additional contact part and an additional connection part, which is designed accordingly for the realization of a screw connection or a crimp connection.
  • an additional channel is provided in the insulating body that is exposed to the outside of the insulating body and has a channel bottom and adjoining side walls on both sides and a receiving element with an outlet opening on the output part of the insulating body.
  • the additional channel is preferably designed in the form of a trough and is only closed off at the front by the outlet part.
  • Both side walls are preferably each provided with at least one anchor part which interacts with at least one additional holding part which is provided on the additional contact element.
  • the at least one anchor part and the at least one additional holding part are preferably designed as mutually corresponding formations or indentations, possibly wall curvatures, which allow the formation of a form-fitting connection.
  • the armature parts can be designed, for example, as protruding latching lugs, while corresponding latching depressions are provided on the additional connection part, which preferably extend perpendicularly to the longitudinal axis of the additional contact element.
  • the additional contact element can be inserted into the additional channel in such a way that the additional contact part or the adjoining front end piece of the additional connection part is held in the receiving element or the outlet opening and the rear end piece of the additional connection part is held by the anchor parts.
  • the additional contact element can therefore be inserted into the receiving element with the front side or the contact element first and then lowered laterally into the additional channel, with the anchor parts and the additional holding parts interacting and forming a latching connection or clamping connection or a positive and/or non-positive connection.
  • a holder is thus created by means of which the additional contact element is held securely.
  • a housing or casing can be provided for the connector units in all of the described embodiments, with or without an additional contact element, optionally taking into account the required protection class and independently of the additional contact element.
