  • a second coding of the coding element 88 can be created by the length of the first fastening areas 84. If the first fastening areas 84 are made relatively long, e.g. B.
  • the length of the coding nose 87 can be designed differently , ie with a long coding nose 87, a different coding is achieved than with a correspondingly shorter coding nose or if the coding nose 87 is omitted.
  • the first and / or the second receiving groove 11, 21 can also be extended even further in this cutting area 30, so that it extends beyond the groove base of the other associated receiving groove.
  • a depression is formed in the groove base of the respective receiving groove running perpendicular thereto.
  • Such a recess can be used to receive one end of a functional element. This end of the functional element can be received in a latching manner (latching edges) and / or clamping in the respective recess. In this way, extraction forces and / or torques acting on the functional element can be absorbed and neutralized.
  • the first receiving groove 11 extends beyond the groove base of the second receiving groove 21, that is to say the cutting area 30 is somewhat elongated counter to the insertion direction S and protrudes further into the material of the housing 2. In this way, a recess is formed in the groove base of the second receiving groove 21.
  • the Figures 11 and 12 show an embodiment in which the second receiving groove 21 is designed to be elongated, that is to say extends beyond the groove base of the first receiving groove 11 in the cutting area 30. In this way, a recess is formed in the groove bottom of the first receiving groove 11.
  • the Figures 13 and 14 show an embodiment in which the respectively elongated first and second receiving grooves 11, 12, as they are based on FIG Figures 9 to 12 have been described, are realized in combination with one another.
  • the first receiving groove 11 thus extends beyond the groove base of the second receiving groove 21 in the cutting area 30.
  • the second receiving groove 21 extends beyond the groove base of the first receiving groove 11 in the cutting area 30. In this way, depressions are formed both in the groove base of the first receiving groove 11 and in the groove base of the second receiving groove 21.
  • the Figure 15 shows the design of the first and second fastening elements 11, 21 in the form of receiving depressions into which the corresponding protruding fastening areas 83, 84 of functional elements 8 can be fastened by insertion.
  • the first fastening elements 11 are each designed as a recess in the first housing wall 10, the special case being shown that the first fastening elements 11 are arranged at the transition from the first housing wall 10 to the second housing wall 20. It would also be possible to form the first fastening elements 11 spaced apart from the second housing wall 20 as depressions in the first housing wall 10.
  • the second fastening elements 21 are designed as depressions in the third housing wall 23.
  • the Figure 16 illustrates the attachment of a functional element 8 in the form of a first latching element 81, which in terms of its latching arm 82 is comparable to the first latching element 81 in the embodiment of FIG Figure 6 can be formed.
  • the first latching element 81 differs from this, however, in the design of its first attachment area 84 and its second attachment area 83.
  • the first attachment area 84 is designed as an angled arm that overlaps part of the third housing wall 23 and with an angled end area into the second, designed as a receiving recess Fastening element 21 engages.
  • the second fastening area 83 is designed as an extension which runs essentially parallel to the second housing wall 20 and which engages with one end area in the first fastening element 11, which is designed as a receiving recess.
  • the end of the second fastening area 83 can be designed with a latching hook.
  • the Figure 17 shows the attachment of two functional elements 8 in accordance with FIG Figure 16 described embodiment in corresponding first and second fastening elements 11, 21 of the connector 1.
  • the functional elements 8 each engage behind a latching edge of the latching element 90 of the mating connector 9 with their latching arm 82.
  • corresponding recesses 92 are provided on the plug side to the fastening elements 11 on the connector 1, which recesses are aligned with the fastening elements 11.
  • the recesses 92 are penetrated by the fastening area 83 of the functional element 8.
  • at least the end edge of the housing of the mating connector 9 facing the fastening elements 11, 21 can be set back from the second housing wall 20 when the connector 1 and mating connector 9 are plugged in. A free space for the passage of the functional elements is thus formed between the mating connector 9 and the second housing wall 20.
