  • the interference fit structure and abutment structure of the core plug 50 also ensure that injection liquid does not enter the pin hole 15 of the connector casing 10 in the process of forming the overmoulded casing 20, thereby solving the technical problem that high liquid injection pressure during forming of the overmoulded casing 20 will cause shifting of the pin 70 and the conductive core 34, as stated in the prior art.

  • the second crimping structure 74 may also take the form of at least one clamping jaw projecting transversely from the pin body 75; for example, two, three or more clamping jaws are provided, in order to be reliably fixed in a press-fit to a peripheral surface of the conductive core 34.
  • the dimensions of the second crimping structure 74 are designed so that there is a sufficiently large crimping area between the second crimping structure and the conductive core 34.

  • a core seal 40 and a core plug 50 are fitted round each conductive core 34, specifically on the insulator 36 thereof.
  • the conductive core 34 is electrically connected to the pin 70.
