  • the invention also includes a plug and socket arrangement for an electrical cable: the plug comprising: a cap portion surrounding an end of the cable; and a plurality of electrical connector pins, one said connector pin being electrically bonded to an earth conductor of said cable and another said electrical connector pin being connected with a signal conductor of said cable; the arrangement being that said pins extend in a direction transverse to a main length of said cable, said pins being surrounded by an insulating tubular sheath which extends beyond a lower extremity of said pins, in a direction transverse to said main length of cable; said socket being in accordance with the socket of claim 15; wherein an outer surface of said sheath is provided with a channel which is specially adapted for engaging a said spline of the socket head of the socket, the arrangement being that the spline of the socket head engages the channel on the sheath, thereby ensuring that a first male connector pin engages a first female connector pin and the second male connector pin engages a second female connector pin.
  • said sheath extends beyond a lower extremity of a connector pin, by a distance in the range 3-lOmm, and preferably at least 6.5mm.
  • Said plug is preferably formed of an inner portion which is formed in a first forming operation, and an outer portion which is formed in a second forming operation.
  • Said first and second forming operations preferably comprise moulding operations.
  • Said plug may comprise a nylon moulding.
  • a plug and socket assembly for fitment to a printed circuit board comprises a socket base 1, a socket head 2, and a plug 3.
  • the socket base comprises for example a nylon base moulding 10 having a base width a, a base length b and a base height c, an upper end of the base having a peripheral seating rim 11, extending around a perimeter of the base, and the base being provided with first and second passages 12, 13 each arranged for receiving a corresponding first or second female electrical connector pin, 20 as shown in figure 8.
  • the passages 12, 13 have a main length which extends in a direction transverse, and in particular perpendicular, to a plane defining a seating surface 15 on a lower side of the seating rim 11.
  • the passages extend between an upper end of the base and a lower end of the base.
  • the passages comprise a first substantially cylindrical section 16, and a second, substantially frusto conical section 17, as shown particularly in figures 5, 6 and 7.
  • a pin seating portion 19 At the upper end of each passage is provided a pin seating portion 19.
  • the pin seating portion in the form of a first and second arcuate walls 21, 22 respectively defining the frusto conical section 17 of the passage.
  • the first and second walls 21, 22 are separated from each other such that they face opposite sides of the passage.
  • the first and second walls are deformable from, and normally return to their frusto conical shape, in which they are originally formed.
  • the electrical connector pin 20 comprises a female crimp pin formed by rolling a sheet of resilient metal into a tubular form, to provide a female socket portion 30, and at an upper end of the pin and a crimp portion 31 at a lower end of the pin. Between the female socket portion and the crimp portion is provided a protruding ring portion 32, of diameter larger than the diameter of the female socket portion.
  • the female pin may be inserted into a said passage 12 or 13 in the base, by inserting the female socket portion 30 of the pin at an upper end of the pin into a lower end of the passage 12 or 13 at the lower end of the base, and pushing the pin in a direction along the passage towards the pin seating portion 19, such that the female socket portion 30 of the pin passes through the pin seating portion, splaying the first and second side walls 21, 22 of the pin portion apart as the ring portion 32 passes through the pin seating portion, the pin seating portion then contracting, as the ring portion passes out of the upper end of the passage, such that the electrical pin seats on top of the pin seating portion 19, the ring 32 resting on top of the ring seating portion and preventing the pin from being drawn back into the passage in a direction from the upper end of the base to the lower end of the base.
  • the crimp portion 31 remains contained within the cylindrical portion 16 of the passage. Since the crimp portion 31 is crimped around an electrical wire, and may be soldered to the electrical wire, when the pin 20 is inserted into the passage 12 or 13, and passed out of the upper end of the passage, so that the ring portion passes through the seating portion 19, if the pin passes too far through the passage, the pin may be withdrawn back towards the passage by pulling the wire connected to the crimping portion 31, such that the ring 32 seats on an upper periphery of the seating portion 19.
  • the head comprises an insulating tubular wall 30 moulded from, from example nylon, the tubular wall closed at a lower end 31 thereof by a floor portion 32 which extends across the lower end of the tubular portion 30, the tubular portion having a substantially oval cross section, the oval cross section comprising first and second semi circles spaced apart and placed oppositely from each other and separated by a linear portion extending between said first and second semi circles, as shown in plan view in particular in figure 13;
  • the lower end 31 of the socket head being provided with first and second locking portions 34, 35 respectively each locking portion comprising an extending arm of a first thickness, having a foot portion of a second, larger thickness, the foot portion comprising a tapered portion, becoming thicker towards a lower extremity of the foot portion 36, the tapered portion as viewed in cross section forming a wedge, the wedge having a lower point extending in a direction along a main length of the head and facing outwardly away from the tubular body;
  • the plug is moulded around an end of a conventional coaxial cable 50 having an outer sheath 51 surrounding concentrically an earth shielding, and contained within the earth shielding an insulator portion 53 surrounding concentrically a central conductor 54.
  • the plug comprises a moulded cap portion 55 the cap portion being moulded in two parts being a first, inner moulded part 54, which is moulded around the end of the coaxial cable, and a second, outer moulded part 57 which is moulded around the inner moulded part.
  • the outer moulded part includes an elongate tubular sheath 59 surrounding first and second substantially cylindrical cavities 60, 61 respectively.
  • first and second male connector pin Concentrically with each cavity are provided a first and second male connector pin, the first male connector pin being electrically connected with the inner conductor 54 of the coaxial cable prior to moulding the cap, and the second male pin being electrically connected with the earthing sheath of the coaxial cable, prior to moulding the head.
  • the tubular sheath 59 extends in a direction perpendicular to a main axis of the coaxial cable, such that connection of a coaxial cable to a printed circuit board may be made with the coaxial cable extending substantially parallel to a main plane of the printed circuit board, when the plug is inserted in the socket as previously described here above.
  • tubular sheath 59 is formed having a channel 63 positioned between the first and second male pins, the channel 63 arranged to engage with the spline 41 of the socket head, to ensure that the first and second male pins engage the respective first and second female pins, and that the plug cannot be inserted into the head of the socket the wrong way engaging the second male pin with the first female pin. This ensures that the earth shielding of the coaxial cable is connected to a corresponding earthed female pin of the socket.
  • an aperture 80 is formed in a printed circuit board 81, the aperture being of dimension such that it closely fits around a perimeter of the base 1.
  • the base is dropped or mechanically placed into the aperture in a direction from above the circuit board, such that the base protrudes through the circuit board, but is prevented from passing completely through the circuit board by the seating rim 11 which sits on the upper surface of the board around the perimeter of the upper end of the base.
  • the socket head is then aligned such that the lower locating lug 45 of the head portion locates within the seating rim 11 of the base, the locking arms 34, 35 respectively on either side of the head, being inserted between the base and the PCB, and through the aperture 80 in the printed circuit board, such that the tapered portions 34, 35 of the locking arms extend through the aperture and to a position below an underside of the printed circuit board.
  • the locking arms which are urged slightly towards each other when passing through the aperture, may expand away from each other their original configuration as formed, thus causing the thicker end of the tapered wedge portions to contact the underside of the printed circuit board at the periphery of the aperture 80, thereby preventing the tapered portions from returning back through the aperture, and thereby locking the lower end of the head to the PCB. Since the base is positioned between the head portion and the PCB, but is prevented from passing through the PCB by virtue of the seating rim 11, the locking arms lock the head portion and the base portion of the socket to the PCB.
  • the first and second female pin connectors may be passed from underneath the PCB, through the lower end of the passages 12, 13 in the base of the socket and, such that the ring 31 on the female pin passes through the pin seating 19, through which it cannot return, the female crimp portion of the female pin being housed within the pin housing 40 of the head portion.
  • the plug 3 may then be inserted into the head of the socket, and pushed down such that the male pins engage the corresponding respective female pin connectors to make firm mechanical and electrical contact between the plug and socket, thereby ensuring firm electrical and mechanical contact between the coaxial cable and the printed circuit board.
  • the plug and socket may be contained within a casing 100, the casing having an aperture 101 through which the upper end of the head may pass, the casing locating on an upper peripheral seating rim 102 formed around an outer surface of the tubular portion of the head. An upper end of the head is arranged to be flush with the outer surface of the casing.
  • the outer surface of the casing is accessible to a person and since the first and second female pins are provided within the tubular socket head, in the pin housings, and the pin housings and female pins are positioned at a depth of at least 11.5mm from the upper end of the socket head, a user is protected from accidentally contacting the female pins when the plug is not connected. Further, since the male pins are enclosed within the insulating sheath 59 of the plug, there being a distance of at least 6.5mm between the tip of the male pins and the lower end of the sheath, the chances of accidentally contacting the male pins and thereby incurring electric shock, are reduced.
  • Specific embodiments of the present invention may have an advantage of providing a socket which can be quickly and easily fitted to a printed circuit board from a position above the printed circuit board, and which is suitable for automated connection of the socket to the printed circuit board.
  • specific embodiments may provide an advantage of providing a socket which is physically shielded, having pins protected from accidental contact due to the inaccessibility of the female pins from a position outside the socket, for anything except the matching plug.
