Definitions

  • the invention relates to a multi-pole connector arrangement with a first connector that has a first connector housing and with a second connector that has a second connector housing, with a plurality of contact elements being arranged in both connector housings, of which at least the contact elements of the first connector housing each have a connecting line are connected, wherein the first and second connector housings are connected to one another by a snap connection, which is secured against accidental disconnection by a CPA latch, and wherein the CPA latch forms a spring clip which consists of two opposing spring arms.
  • a connector housing has a CPA latch with two opposing elastic spring arms. The spring arms are used to guide and lock the CPA latch in the connector housing.
  • the publication US 2015/0162 693 A1 shows a multi-pin connector that has an attachable cable holder on which several connecting cables can be bundled. A separately mounted terminal is provided for fastening the connecting cables.
  • the cable holder can be designed to be connected to a CPA device.
  • the task was to create a connector arrangement which enables the attachment of a large number of connecting cables with a particularly low level of material and assembly effort.
  • the CPA latch simultaneously forms a cable holder for fastening several connecting cables arranged parallel to one another, and in that parallel bundled connecting cables are inserted into the spring clamp and held by the clamping force of the spring clamp.
  • the part of the CPA bar that forms the line holder is therefore designed as a spring clip which consists of two opposing spring arms.
  • the spring clips are bundled in parallel Connecting cables are easily inserted and held by the spring clip.
  • the CPA latch can advantageously be designed as a single part manufactured independently of the connector housings, which can be locked into place by plugging it into at least one of the connector housings.
  • connecting cables into a cable bundle by means of a connecting element before inserting them into the spring clip.
  • the CPA latch 40 has two opposite spring arms 43 on its side projecting from the connector housings 12, 22 (clearly visible in the Figure 2 ), which hold a cable bundle 32 of connecting cables 30 in a clamping manner.
  • Both connector housings 12, 22 have electrical contact elements that can be connected to one another, such as socket contacts and plug pins, which, however, are not shown in the figures.
  • first connector housing 12 and a CPA latch 40 are each shown as individual parts.
  • a locking slide 50 is shown.
  • the first connector housing 12 has a plurality of receiving chambers 48 which are arranged in two parallel rows.
  • the receiving chambers 48 are intended to accommodate electrical contact elements, not shown here, in a latching manner.
  • a cuboid-shaped and elongated locking plate 52 of the locking slide 50 is inserted into a locking channel 19 which runs through the entire length of the first connector housing 12.
  • a locking lever 54 arranged on the locking slide 50 locks with the first connector housing 12, whereby the locking slide 50 is fixed on the first connector housing 12.
  • the locking plate 52 inserted into the locking channel 19 engages behind a release on the contact elements and thus effects a secondary locking of all contact elements.
  • the principle of such a lock is, for example, from the German patent DE 103 32 892 B4 known.
  • the first connector housing 12 has a recess 13 in the housing wall in the middle of one of its long sides, within which a resilient lever 17 is arranged, on which two bow-like locking elements 15, 16 are arranged one above the other.
  • locking grooves 14 are formed one above the other in the housing wall of the first connector housing 12.
  • the locking grooves 14 are intended to interact with locking webs 44 that are formed on the side surfaces of the CPA latch 40. Between the side surfaces of the CPA latch 40, a formation can also be seen that forms a wedge 46.
  • the CPA bar 40 can be connected to the first connector housing 12 via the locking webs 44 and the locking grooves 14, the interaction of the locking webs 44 and the locking grooves 14 enabling at least two locking positions of the CPA bar 40 on the first connector housing 12, which are referred to below as Pre-locking position and final locking position are referred to.
  • the Figure 4 shows the CPA latch 40 in the pre-locking position on the first connector housing 12.
  • the two locking webs 44 on the side surfaces of the CPA latch 40 are inserted into the top two locking grooves 14 of the recess of the first connector housing 12.
  • the wedge 46 of the CPA latch 40 is located between the upper locking element 15 and the lower locking element 16 of the first connector housing 12.
  • the resilient lever 17 can thus continue to be pivoted so that when the first connector housing 12 is joined to the second connector housing 22, the lower locking element 16 can lock into the locking recess 24 of the second connector housing 22.
  • the CPA bar 40 is then brought into its final locking position by pressing down, which means that it is in the Figures 1 and 2 shown assembly state results.
  • the CPA latch 40 fulfills the additional function of fixing the connecting cables connected to the contact elements of the first connector part 10 to the first connector housing 12.
  • the connecting cables 30, which are optionally combined into a cable bundle 32 by an additional connecting element 34, such as a cable tie or adhesive tape, are inserted into the spring clip 42 belonging to the CPA latch 40.
  • the clamping force of the two spring arms 43 of the spring clip 30 fixes the cable bundle 32 of the connecting cables in an outlet direction that is approximately at a right angle to the plug-in direction of the two connectors 10, 20.
