Definitions

  • the invention relates to a connector for electrically conductive cables, in particular for stranded cables.
  • Connectors of this type are required in order to connect the cable ends of electrically conductive cables to one another at desired locations in an electrically conductive manner. It is not only important to make the electrical contact reliably, but the connection must also be able to withstand mechanical stresses, because if the connection is mechanically destroyed, the electrical contact is inevitably interrupted.
  • the most commonly used connectors are the known luster terminals, and besides, especially in motor vehicles - depending on the respective vehicle type - very specific adapters are used according to the principle of a connection with plug and coupling.
  • the luster terminals have hole-shaped openings on two opposite sides to accommodate the cable ends to be connected. These must first be stripped and then inserted into the opening using screws that are screwed in perpendicular to the cable ends.
  • the adapters - also referred to as compact plugs - are connected to the cable ends.
  • the cable ends not only have to be cut to the appropriate length, rather, it is also necessary to take off the insulation. This involves an additional work process and presupposes the presence of appropriate tools.
  • the invention has for its object to provide a connector for electrically conductive cables, which enables the establishment of a secure electrical connection without additional tools with simple means.
  • a connector is created with surprisingly simple measures, which can be referred to as a quick connector, and which enables the safe establishment of an electrically conductive connection in one easy operation. It is only necessary to lead the cable ends into corresponding cable openings in the connector and to move them briefly or jerkily in the opposite direction (pull out) in order to establish the electrical connection between the two cable ends.
  • a major advantage is therefore that the new connector does not require the cable ends to be stripped beforehand. Rather, the cable ends with their insulation can be inserted into the cable openings. Because of the spring ends located within the cavity of the connector, which are designed in the manner of a knife with a cutting edge, an electrical contact is created in that the spring ends cut into the insulation during a short movement opposite to the insertion of the cable ends, and electrically penetrate the conductive cable. In this position, the spring ends assume a stable position so that the electrical contact remains.
  • an electrically conductive connection can be made even in the tightest of spaces, since it is only necessary to insert the cable ends into the cable openings.
  • the new connector is therefore particularly suitable for the production of electrically conductive connections in a confined space, for example behind dashboards in motor vehicles.
  • a slot-shaped is above a cable opening Opening provided in the housing through which an unlocking rod can be inserted into the cavity. This makes it possible, if necessary, to disconnect the electrical connection previously made with the new connector and to remove the cable ends from the cavity.
  • the illustrated and as a whole with the Be 1 and 2 consists of a housing 14 with a cavity 12. Inside the cavity 12, a contact spring 16 with a central web 18 and two spring ends 20 is arranged. In the idle state, the contact spring 16 assumes the position shown in FIG. 1.
  • a cable opening 22 approximately at the level of the housing base 30 with a rough surface. Cable ends 24 can be inserted through these cable openings 22 and are to be electrically connected to one another. The cable ends 24 can be led up to a maximum of an insertion limit 32 provided centrally in the cavity 12.
  • the cable ends 24 are passed together with their insulation 58 through the cable openings 22, i.e. it is not necessary to strip the cable ends beforehand.
  • the spring ends 20 When the cable ends 24 are inserted, the spring ends 20 initially lift somewhat out of their rest position. As shown in FIGS. 3-5, the spring ends are knife-like at the bottom and have one in the area of a recess 34 Cutting edge 26 or a tip 36. Now that the cable ends 24 have been inserted into the cavity along the central axis 28 of the cable openings 22, they are briefly stressed in the direction of arrows A and B in FIG. 2. The spring ends 20 cut into the cable ends 24 with the cutting edges 26 or with the tip 36 and penetrate their insulation 58 as shown in FIG. 4 up to the electrically conductive strands 56. According to the illustration in FIG. 2, this is via the contact spring 16 the electrically conductive contact between the two cable ends 24, which are held mechanically stable in the connector 10. The central web 18 of the contact spring 16 runs at a distance from the upper housing wall and extends approximately to the insertion limit 32.
  • 6 to 11 show a multi-pole connector which has a contact housing 38, in which a multiplicity of cavities 12 with the associated contact springs 16 are arranged next to one another.
  • the spring housing 38 has two first lateral openings 48 on the outside and two lateral openings 50 above it. These openings are intended for receiving a fork arm 44 of a fork 40 made of insulating material.
  • the fork 40 according to FIGS. 6, 8 and 9 is guided with its one fork arm 42 through the first lateral openings 48. A secure hold is ensured by a locking lug 46 provided on the second, outer fork arm 44.
  • the fork arm 42 forms the previously mentioned insertion limitation (see FIG. 32 in FIGS. 1 and 2).
  • the fork 40 is removed and inserted with its fork arm 42 into the upper side openings 50, as shown in FIG 7, 10 and 11 is shown.
  • the fork arm 42 advantageously ensures 11 that the central web 18 according to FIG. 11 in any case maintains its bent position shown there and cannot deflect upwards, which could result in a defective electrical connection.
  • the contact housing 38 still has a slot-shaped opening 52 above the cable opening 22.
  • a flat unlocking rod 54 can be inserted if necessary, if there is a desire to remove the electrical connection and lead the cable ends 24 out of the contact housing 38 again.
  • the spring ends 20 are raised in the manner shown, so that it is now possible to remove the cable ends 24.
  • the novel connector 10 is advantageously also suitable for releasably making electrical connections.
