Definitions

  • the document DE 35 37 722 C2 has disclosed an electrical plug connector which has a plurality of poles and comprises a cuboid contact housing having at least one row of contact chambers, into each of which a contact element can be inserted and latched, and which, for each contact chamber, has a plug-in opening for a mating contact element in the front wall.
  • the electrical plug connector comprises an elongate slot, running transversely with respect to the plug-in direction of the contact elements, in the same longitudinal wall associated with each row of contact chambers; the elongate slot penetrates the respective longitudinal wall and can have a respective locking bar pushed into it, which engages behind an edge of the respective contact element.
  • a surrounding housing containing the locking bar is pushed onto the contact housing in order to secure the contact elements situated in the chambers, with the result that the locking bar enters the elongate slot.
  • the document US 4,436,361 has disclosed a hermaphroditic cover which is pushed, transversely with respect to the plug-in direction of a plug connector, onto the contact element chambers so that the contact elements are relieved of tension.
  • this hermaphroditic cover serves as a secondary locking mechanism for the contact elements in the contact chambers, and, on the other hand, it serves as a cover for the cable outlet.
  • a particular disadvantage of these two documents is that there is no kind of simultaneous securement for the mating connector.
  • the surrounding housing or the hermaphroditic cover is used merely for fixing the electrical contacts in their corresponding chambers.
  • the document EP 0 667 654 B1 has disclosed an electrical connector having an improved unlocking and locking device.
  • This electrical connector comprises a module with plug-in shoes situated in the chambers, a connector housing, a matching cover for the latter and a mating connector housing with terminal or contact strips extending in the plugging direction.
  • the module needs to be pushed into the connector housing, with a connector housing bar which projects into the chambers providing secondary locking for the contact shoes.
  • the cover is pushed over that, so that the cables crimped into the cable shoes are relieved of tension.
  • the cover has four sliding blocks which point laterally outwards and are inserted into guide grooves made in the side walls of the mating connector.
  • a particular disadvantage of this is that, during the process of inserting the connector into the mating connector, a transverse force acts on the contact elements, because the corresponding matching contact elements encounter a component running at right angles to the plug-in direction. It is then possible for the terminal strips or the contact strips to be bent as a result of the connector becoming wedged.
  • such a connector is not suitable for breaking or making a connection between the connector and mating connector during operation (it does not enable so-called "hot plugging"), because terminal strips, for example, can successively make contact with various contact shoes, situated in consecutively arranged chambers, during the plug-in process.
  • the assembly of such a connector is time-consuming and requires a large number of parts.
  • the object of the invention is to present an electrical plug connector which is easy to assemble, requires few parts and does not bend the contact elements when plugged in.
  • the cross-slide can lock the two plugged-in connectors to one another and secure the contact elements situated in the contact chambers, and, when the cross-slide is pushed in, the locking bar projecting into the contact chambers can be moved in the groove and, at essentially the same time as this, the first two guide elements slide into one another, so that the connectors can be guided towards one another.
  • the particular advantage afforded by the invention is that it is economical because the plug connector according to the invention comprises few parts and is easy and quick to assemble.
  • Figure 1 shows an exploded view of a first embodiment of an electrical plug connector according to the invention having a contact connector 1, a cross-slide 5 and a mating connector 4.
  • the essentially cuboid contact connector 1 has contact chambers 2 which extend in the plugging direction and into which contact elements (not shown) are inserted.
  • L-shaped grooves 3 running transversely with respect to the plug-in direction are made laterally in the side faces of the contact connector so as to project into the contact chambers 2.
  • Integrally formed on each side in the bottom half of the contact connector 1 are two mutually parallel L-shaped guide shoulders 9 which extend transversely with respect to the plug-in direction and over the full width of the contact connector 1.
  • Each guide shoulder comprises two limbs 31, 32 which are of essentially the same length and form an angle of approximately 90°.
  • Two guide shoulders 9 are arranged on one side such that the two free limbs 32 point away from one another and the two attached limbs 31 are integrally formed on the side of the contact connector 1.
  • the mating connector 4 comprises the first guide elements, which are integrally formed on the two opposite side faces 15 and 16 as sliding blocks 10.
  • These guide elements 8 are in the form of a guide groove 8 which runs at an angle and whose end region 14 runs transversely with respect to the plug-in direction, the start region of this guide groove 8 opening into the top edge of the outer side walls 11.
  • the inner side walls 12 each comprise, close to their top edges, an inwardly pointing locking bar 6 which runs transversely with respect to the plug-in direction and is shaped to be complementary to the groove 3.
  • a second embodiment is described below, explaining only the differences compared with the first embodiment.
  • This embodiment has somewhat differently designed third guide elements and guide shoulders.
  • Figure 2 shows an exploded view of a second embodiment of the electrical plug connector according to the invention.
  • This likewise has a contact connector 1 having contact chambers 2 and a groove 3, and the guide shoulder 29 surrounds the bottom edge of the contact connector 1 in a U shape.
  • the contact connector 1 and the guide shoulder 29 are connected to one another by means of a baseplate 27, so that an interspace for holding the third guide element 26a, b is produced between the side faces of the contact connector 1 and the inwardly pointing edge 28 of the guide shoulder 29.
  • the mating connector 4 does not differ at all from the mating connector in the first embodiment, so that there is no need to explain it in more detail.
  • the cross-slide 5 in the second embodiment likewise has two outer side walls 11 which, unlike in the first embodiment, do not extend over the full height, and two inner side walls 12, which extend over the full height and have the L-shaped third guide elements 26a, b integrally formed on their bottom edge on the outside.
  • the outside walls and inside walls 11 and 12 are likewise connected to one another by means of a transverse web 24 and 25.
  • a groove for holding the top limb 30 of the guide shoulder 29 is produced between the transverse webs 24 and the third guide elements 26a, b.
  • the contact connector 1 is in a prelatching position in the cross-slide 5, i.e. the contact connector 1 is partially pushed into the cross-slide 5, with latching elements (not shown) locking it in this prelatching position.
  • the guide shoulders 9; 29 slide into their corresponding third guide elements 26a, b.
  • the locking bar 6 enters the groove 3 and at the same time checks whether the contact elements situated in the chambers 2 have been inserted correctly.
  • the mating connector 4 and its outwardly pointing sliding blocks 10 are now inserted into the guide groove 8.
  • the contact elements situated in the mating connector 4 are aligned with their corresponding contact elements on the contact connector 1, so that the assembler need merely push together the cross-slide 5 and the mating connector 4 transversely with respect to the plug-in direction.
  • the sliding blocks 10 slide along the guide groove 8, with the result that the mating connector 4 is guided towards the contact connector 1.
  • the plug connector is in the latched position, in which case the contact connector 1 and the mating connector 4, on the one hand, and the contact elements situated in the contact chambers 2, on the other hand, are secured by the cross-slide 5.
