Definitions

  • the invention relates to a coaxial connector element for connection to a pin header.
  • the invention is therefore based on the object of designing a coaxial connector element in a manner suitable for connection to a pin header.
  • Such a coaxial connector element is designed either with two or with four contact blades. Sufficient contacting in some cases can already be achieved with two contact blades, but the connector element is preferably designed with four contact blades.
  • the coaxial connector element according to the invention is formed with the outer contact lamellae and the inner inner conductor bushing in a manner which is well suited for connecting a coaxial cable to the pins of a pin strip, the contact with the pins being established without additional measures simply by plugging the coaxial connector element onto the Pin header is done in a safe manner.
  • plugging the connector element for example on a 9-pin field of a pin header, two or preferably four pins and a center pin are contacted with contact lamellae in accordance with the design and arrangement.
  • a pin array of 9 x 5 pins can then be contacted with an 8-way connector in a very confined space.
  • the connector element according to the invention in spite of its formation with contact lamellae, requires practically no larger dimensions on its outer circumference, so that it can be made particularly compact and is particularly well suited for connecting coaxial cables to NF pin headers with a large number of closely adjacent pins.
  • the contact lamellae are expediently formed by spring arms of a sleeve secured against rotation on the outer circumference of the connector element.
  • the connector element is designed in a particularly simple manner with contact lamellae.
  • the resilient contact lamellae extend away from the end of the connector element in its longitudinal direction and project obliquely to its longitudinal axis in the unloaded state.
  • a ring is fixed on the connector on the side of the contact lamella facing the pin strip, e.g. is pressed on, which is provided with a number corresponding to the number of contact blades of outwardly open and aligned with the contact blades grooves.
  • a ring is used with its grooves to pre-position the connector element during the plugging process, so that the contact lamellae are securely fed onto the pins of the pin header and do not get into the spaces between the pins.
  • an insulating part with a pre-centering hole for the central pin is arranged in front of the inner conductor bushing, so that a secure engagement of the central pin in the inner conductor bushing is also ensured.
  • the coaxial connector element according to the invention is expediently constructed such that it has an outer conductor sleeve made of conductive material, on one of which The contact lamellae are provided on the outside and the inner conductor socket is arranged on the inside and a coaxial cable is connected to the other end.
  • the coaxial connector element according to the invention is particularly well suited for the connection of coaxial cables to an NF pin header.
  • the connector element is combined to form a unit together with other similar connector elements in a connector housing.
  • the connector housing can be coupled to a transfer connector provided on a mounting plate together with a pin header.
  • the connector element is formed on the outer circumference of its end which can be connected to the pin header, preferably with four resilient contact lamellae 3 which are arranged at the same distance from one another and which, in the embodiment shown in FIG fixed sleeve 4 are formed of conductive material, extend away from the end of the connector element in its longitudinal direction and project obliquely to its longitudinal axis in the unloaded state.
  • four resilient contact lamellae 3 which are arranged at the same distance from one another and which, in the embodiment shown in FIG fixed sleeve 4 are formed of conductive material, extend away from the end of the connector element in its longitudinal direction and project obliquely to its longitudinal axis in the unloaded state.
  • other embodiments of outwardly projecting contact lamellae are also possible.
  • the contact lamellae 3 are used when plugging the coaxial connector element onto a pin strip for making contact with pins, with four pins lying at the corner points of a square being contacted in the case of four contact lamellae arranged in the manner shown.
  • This contact principle is illustrated in Fig.2.
  • the four pins 6 are contacted by contact lamellae 3 and thus connected to the outer conductor sleeve 1 of the coaxial connector element.
  • the pins of the pin field 5 are arranged here with the same spacing of, for example, approximately 2.5 mm and are square, whereby they can have a cross section of, for example, approximately 0.55 to 0.65 mm.
  • the pins can also be round.
  • a ring 7 is fixed on the outer conductor sleeve 1, e.g. pressed on, which is provided with a number of grooves 8 corresponding to the number of contact blades 3, here here with four grooves, which are aligned with the contact blades and are open to the outside. With its grooves 8, this ring serves to preposition the connector element, i.e. the position assignment between the contact lamellae 3 and the pins 6 of the 9-pin field 5.
  • an inner conductor socket 10 made of conductive material is provided in the interior of the plug connector element. Slats 3 is firmly positioned.
  • the inner conductor socket 10 is surrounded by an insulating part 11 designed as a support disk and centered in the outer conductor sleeve 1 by its positioning lug 12.
  • the insulating part 11 is inserted into the outer conductor sleeve 1 from the cable side, the positioning lug 12 being guided in a longitudinal slot 13 of the outer conductor sleeve.
  • the end face 16 of which lies in front of the inner conductor socket 10 has a pre-centering hole 17 for the center pin 9 to be inserted into the inner conductor socket.
  • the Inner conductor socket 10 conductively connected to the stripped inner conductor 18 of the coaxial cable 2, for example soldered.
  • the outer conductor 20 of the coaxial cable which is freed from the outer insulation 19, for example consisting of a shield braid, is conductively connected to the outer conductor sleeve 1, for example also soldered, for which purpose the outer conductor sleeve is formed with a suitable number of solder holes 21.
  • FIG. 3 An application example of a coaxial connector element according to the invention is shown in FIG. 3 or in FIG. 6.
  • a connector element designed according to FIG. 1 with four contact lamellae, together with seven further similar connector elements, is combined as an 8-way connector 30 in a common connector housing 31 to form a unit, each for connection to a field of 9 ⁇ 5 mm.
  • the pin header 32 is as in Figure 3 with an assembly 35, e.g. a circuit board, or as connected in Figure 6 with a female connector 36.
  • the outer conductors of the coaxial cables are connected to the respective connector housing 31, so that an RF-tight coax interface transition is realized.
  • the contact lamellae 3a are formed by a contact boss 37 as projecting outwards.
  • a total of eight coaxial connector elements accommodated in a plug housing 31 can be used to pinpoint the whole 9 x 5 pin field 38 of a pin strip, the corresponding contact principle being shown in FIG. 5 and - as already with reference to of Fig. 2 was explained - with the help of the outer four contact lamellae 3 and 3a, a connection between the respective outer cable and the pins 39 located at the corner points of a square and with the help of the inner conductor socket 10, a connection between the respective inner cable and a central pin 40 of the pin field 38 takes place.
