Definitions

  • the present invention relates to an electrical connector and, more particularly, to an electrical connector which can maintain conduction over a limited displacement during expansion or contraction of the connector.
  • a typical prior art connector includes a first connecting end electrically conductively connected to a second connecting end.
  • the electrical connection between the two is made by a braid woven from conductive material such as copper strands or the like.
  • Removeable electrical connection is made to the end of the second connecting end by a contact arm.
  • cables or other electrically conductive arrangements are connected to both the first connecting end and to the contact arm of the second connecting end.
  • an electrical connector having a first connecting end and a second connecting end and wherein the first connecting end is electrically conductively slidable with respect to the second connecting end.
  • one of the connecting ends has an electrically conductive pin protruding therefrom and the other end has a socket defined by an electrically conductive cylinder, the pin being adapted for electrically conductive slidable insertion within said cylinder.
  • the cylinder may have a circumferential groove located on an inner surface thereof adapted to retain a spring element .
  • a spring element may comprise a mid section lying in a first plane and end sections lying in a second plane, the second plane being offset a radial distance from the first plane.
  • the first plane is parallel to said second plane.
  • the mid section of the spring element may be adapted to be urged against an exterior surface of said pin whilst said end sections are adapted to be urged against an inside surface of said electrically conductive cylinder as a consequence of radially induced tension within said spring element.
  • the inside diameter of said spring element permits of an electrically conductive sliding friction connection with the exterior surface of said pin as said pin moves past said spring element within said cylinder.
  • the electrical connector includes an additional helical spring adapted to resist displacement of the connecting ends towards each other.
  • the helical spring comprises an outer spring mounted around and longitudinally along the outside of said socket and pin.
  • Fig. 1 is a partly sectioned side view of an electrical connector according to one embodiment of the present invention, with the connector shown in an expanded position,
  • Fig. 2 is a view similar to Fig. 1 with the connector shown in a contracted position
  • Fig. 3 is an enlarged view of the spring element shown in Figs. 1 and 2.
  • the electrical connector 20 comprises a first connecting end 21 and a second connecting end 22 adapted for relative axial movement with respect to one another whilst maintaining an electrical connection therebetween.
  • the first connecting end 21 includes a socket portion 23 protruding therefrom in the direction of second connecting end 22.
  • the socket portion 23 comprises an electrically conductive, open ended, hollow cylinder 24 that defines a cylindrical cavity 25 therein.
  • a circumferential groove 26 On the inner surface of the cylinder 24, located towards its open end, there is a circumferential groove 26 adapted to receive and retain electrically conductive spring element 27.
  • the spring element 27 is sized so that it can be inserted when compressed into the cylindrical cavity 25 from the open end of the cavity. The spring element 27 expands into and is retained by groove 26 as it is moved down cavity 25 at the time when the electrical connector 20 is being assembled.
  • Spring element 27 is sized and shaped such that when pin 28 is slidably inserted into cavity 25, it will be frictionally electrically connected via spring element 27 to socket 23 and hence to first connecting end 21.
  • spring element 27 comprises a mid section 37 lying in a first plane and end sections 38, 39 lying in a second plane.
  • the end sections 38, 29 are attached to opposed ends of mid section 37 by way of respective connecting portions 40, 41 such that the plane of the mid section 37 is offset a predetermined radial distance from the plane of end sections 38, 39.
  • Pin 28 protrudes in the direction of first connecting end 21 from second connecting end 22.
  • the first connecting end 21 terminates in a first cylindrical member 29 fixedly and electrically connected to pin 28.
  • the second connecting end 22 includes a second cylindrical member 30 adapted for abutting electrical connection to first cylindrical member 29 by way of contact surfaces 35, 36.
  • Outer helical spring 31 is mounted around and longitudinally along the outside of socket 23 and pin 28, as generally illustrated in Figs. 1 and 2, so as to provide resistance to the approach of pin 28 towards and into socket 23 by action against faces 32, 33.
  • an electrically conductive member such as a wire (not shown) is constrained for electrical conduction within the first connecting end 21 by compressive fit within aperture 34.
  • the second cylindrical member 30 is also electrically conductively connected to an electrically conductive member (not shown) .
  • the second cylindrical member 30 can be electrically connected to the first cylindrical member 29 by axial abuttment of contact surfaces 35, 36 which, in the process of being effected, causes the second connecting end 22 including pin 28 to approach the first connecting end 31 whereby pin 28 slides within socket 23 to a limit of contracted movement as shown in view B of Fig. 2.
  • the components comprising the first connecting end 21, (including cylinder 24), the spring element 27, the pin 28, the first cylindrical member 29 and the second cylindrical member 30 will be made from electrically conductive material so as to effect an electrically conductive connection throughout the electrical connector 20. Insulating material may be applied to the outside of the connector as appropriate and if necessary.
  • the electrical connector of the invention may be used wherever two electrical leads are to be releasably connected together.

Abstract

Un connecteur électrique (20) a une première extrémité de connexion (21) et une seconde extrémité de connexion (22), la première extrémité de connexion (21) pouvant glisser par rapport à la seconde extrémité de connexion (22), tout en conservant le contact électrique. L'extrémité de connexion (22) porte une goupille saillante et conductrice d'électricité (28) et l'extrémité de connexion (21) a une douille (23) formée par un cylindre conducteur d'électricité (24). Le cylindre (24) a une rainure circonférentielle (26) se trouvant sur une surface interne du cylindre (24), agencée pour retenir un élément de ressort (27). L'élément de ressort (27) assure une connexion électrique par friction, avec l'extérieur de la goupille (28), lorsque celle-ci se déplace.
