Definitions

  • the present invention relates to a pin for adapting electrical connectors, and in particular for adapting a socket contact within an existing connector for use with a mating connector with sprung contacts.
  • the invention also relates to a kit of parts for adapting a socket contact, and a mating connector with sprung contacts.
  • Electrical connectors consisting of a mating pair, made up of a plug half and receptacle half, are well known. These types of connector pairs are often designed based on military standards.
  • the mating receptacle half is usually provided on a removable portion of the equipment.
  • a pin for adapting a socket contact of a connector comprising: a shaft portion having a first end and a second end, the first end being tapered; an electrical contact portion provided at the second end, having a greater diameter than the shaft portion; and at least one barb, disposed on the shaft portion, configured to engage with the connector upon insertion of the pin into the socket contact.
  • providing such a pin enables a plug and receptacle mating pair having socket contacts to be adapted for use with a sprung contacts as opposed to insertion contacts.
  • Providing the pin with at least one barb which engages with the connector prevents the pin from being removed once it is inserted, and thus permanently adapts the connector.
  • the pin therefore prevents the ingress of debris, dirt, dust, and/or moisture into the socket contact, and where such debris, dirt, dust and/or moisture is deposited on the connector it may be easily wiped off the contact portion of the pin before the sprung contact receptacle connector is coupled to the plug connector.
  • pins means that the existing, difficult to replace, socket contact connectors can remain in place, but be provided with the advantages associated with a sprung contact connector mating pair.
  • the invention will now be described with reference to use in adapting socket contacts in a plug connector for use with a receptacle connector having sprung contacts.
  • the socket contacts may be provided in a receptacle connector, the sprung contacts being provided in the plug connector.
  • the present invention may be used to adapt any suitable socket contact type connector for use with sprung contacts.
  • the tapered first end is hemispherical.
  • the first end may be conical, or frustoconical.
  • the pin has a substantially circular cross-section, and is preferably sized to be a locational interference fit within the socket contact. Sizing the pin in this manner ensures a good electrical connection between the pin and the socket contact.
  • the or each barb may comprise a tapered face, facing the first end of the shaft portion, and an engagement face, facing the second end of the shaft portion.
  • the tapered face may enable the pin to be more easily located and inserted into the socket contact.
  • the engagement face is configured to engage with the socket contact, and may engage with the rear face of a housing of the plug connector. That is to say, it engages with the internal face of the housing.
  • the housing of such a plug connector may be a socket insert, the plug connector having an outer shell for receiving the insert. The pin is therefore, in effect, permanently attached to the plug connector.
  • the socket insert may be provided in an outer shell of the receptacle connector half of the mating pair of connectors.
  • the radius of the barb portion preferably has a minimum tolerance of about 0.05 mm larger than the maximum tolerance value for the hole in the plug connector, for example the hole in the plug connector housing known as the socket insert which the pin passes through upon insertion into the socket contact. This means that when the barb portion passes through the hole it will temporarily cause the socket insert to deform, and when it has passed through returns to its original form preventing the contact from being removed for the plug connector.
  • the pin comprises a single barb, the tapered face extending around substantially the entire circumference of the shaft portion, and the engagement face extending around substantially the entire circumference of shaft portion.
  • the electrical contact portion is preferably in the form of a disc.
  • the disc has a contact face for electrically coupling with an electrical connector, such as a sprung contact receptacle connector, and a mating face, for mechanically mating with a portion of the plug connector.
  • the mating face is preferably frustoconical.
  • the contact face of the contact portion is planar.
  • the contact face of the contact portion may be concave.
  • the cross-sectional profile of the concave face may be curved, and may be symmetrical such that a dome shape is provided.
  • the concave face of the contact portion has a cross-sectional profile that is triangular. In this way, a cone shaped indentation in the contact face may be provided.
  • the distance, along the length of the shaft portion, between the at least one barb and the contact portion is configured such that, upon insertion of the pin into the socket contact of the plug connector, the barb engages with an internal surface of the connector, and an outer edge of the contact portion is substantially planar with an outer surface of the connector. It is also preferable that the distance along the length of the shaft portion between the mating face of the contact portion and the engagement face of the or each barb, is configured such that, upon insertion of the pin into the socket contact of the plug connector, a housing portion of the connector, disposed between the barb and the contact portion is placed under compression by the barb and contact portion. In this way, a secure fit is provided preventing movement of the pin relative to the plug connector's mating face and also substantially preventing the ingress of debris, dust, dirt and/or moisture into the socket contact.
  • At least the surface of the shaft portion and the surface of the contact portion may be gold-plated.
  • the entire pin is gold-plated, for ease of manufacture.
  • the pin may be coated with another non-corrosive, highly conductive, metal.
  • the electrical contacts surfaces of the pin are the outer surface of the shaft portion between the first end and the barb, and the contact face of the contact portion. It is therefore advantageous that the plating extends at least along and between these surfaces.
  • the pin may be formed of Beryllium copper (BeCu) or Phosphor bronze, and then plated with gold, or another non-corrosive, highly conductive metal.
  • a kit of parts for adapting a socket contact of a connector comprising: at least one pin for adapting a socket contact of a connector as described herein; and a mating connector with sprung contacts for electrically coupling with the adapted connector, comprising: a housing configured to be mechanically coupled to the adapted connector; at least one sprung electrical contact, mounted to the housing, to be electrically coupled to the pin, or a respective one of the pins, upon mechanical coupling of the mating connector and the connector.
  • the kit comprises a plurality of pins, the mating connector comprising a corresponding plurality of sprung electrical contacts.
  • the adapted connector is preferably a plug connector, the mating connector preferably being a receptacle connector.
  • the adapted connector may be a receptacle connector, the mating connector being a plug connector.
  • any feature in one aspect of the invention may be applied to other aspects of the invention, in any appropriate combination.
  • any, some and/or all features in one aspect can be applied to any, some and/or all features in any other aspect, in any appropriate combination.
  • FIGS 1 and 2 show a pin 100 according to the present invention.
  • the pin 100 comprises a shaft portion 102 having a first end 104 with a taper, and in this embodiment rounded taper, a second end 106 in the form of a contact portion, and a barb 108.
  • the contact portion 106 has a contact face 110 and a mating face 112.
  • the barb 108 has an engagement face 114.
  • the pin is configured to adapt a plug connector, upon insertion of the pin into the or each socket contact, to enable use with a receptacle connector having sprung contacts.
  • the shaft is substantially cylindrical in shape, and thus has a circular cross-sectional shape.
  • the pin is inserted in the existing socket contact by a user.
  • the rounded end 104 of the pin enables the pin to be more easily located and aligned in the socket contact.
  • the user must exert sufficient force to push the barb passed the outer housing, until it emerges on the other side of the outer housing, and engages with the rear, internal, surface of the outer housing.
  • the distance along the length of the shaft, between the engagement face 114 and the mating face 112 is configured such that engagement face 114 and the mating face cooperate to retain the pin within the plug connector without the pin being able to move in the axial direction of the pin 100. That is to say, the housing of the plug connector, such as a socket insert, is clamped between the barb and the contact portion.
  • the dimensions of the pin are such that the outer edge of the contact face 110 is planar with the outer surface of the housing. That is to say, the contact face is flush with the socket insert mating face.
  • the barb 108 is of a frustoconical shape facing the first end 104 of the pin 100.
  • the shape enables the pin 100 to be more easily inserted into the socket contact of the plug connector.
  • the mating face 112 of the contact portion 106 is also of a frustoconical shape, and also faces the first end 104 of the pin 100.
  • the shape of the mating face 112 is configured to correspond to the shape of the opening of the socket insert, and so may not be frustoconical.
  • the contact face 110 is substantially flat.
  • the contact face may be concave, which may improve the electrical connection between the sprung contact and the pin.
  • the pin 400 shows the cross-sectional shape of the contact face with a smooth curve 402, and thus a dome shaped contact face is provided.
  • the pin 500 shows the cross-sectional shape of the contact face as being triangular 502, and thus a cone shaped contact face is provided.
  • the pin may be formed of any suitable electrically conductive material, such as Beryllium copper (BeCu) or Phosphor bronze, and may be coated with a non-corrosive, highly conductive, metal such as gold.
  • a suitable electrically conductive material such as Beryllium copper (BeCu) or Phosphor bronze
  • BeCu Beryllium copper
  • Phosphor bronze Phosphor bronze
  • Figure 6(a) shows the pin 100 being inserted into a plug connector 600.
  • the plug connector 600 has an outer casing, known as a shell, which in use mechanically couples with the other half of the mating pair of connectors, a socket connector housing 604, in the form of a socket insert, having an external face 606 and an internal face 608, and a socket contact 610.
  • the diameter of the pin 100 is such that a locational interference fit is formed between the pin 100 and the socket contact 610.
  • the barb 108 passes through the opening in the socket insert 604, and engages with the internal face 608 of the socket insert 604.
  • the mating face of the contact portion mates with the outer surface 606 of the socket insert 604, the contact face of the pin 100 being flush with the outer surface 606.
  • Figure 7(a) shows a sprung contact receptacle connector 700, which is also known as a pogo connector, and Figure 7(b) shows the permanently adapted plug connector.
  • the receptacle connector 700 and the plug connector 600 form the complete assembly.
  • the socket insert 604 may alternatively be provided in the receptacle connector 700 outer shell.
  • the sprung contacts are provided in the plug connector outer shell.
