Definitions

  • This invention relates to a device permitting the connection of electrical conductors provided at least one of their ends with a male connecting means adapted to be engaged and detachably locked in a conductor pin mounted in an insulating support.
  • the invention also relates to supports comprising any number of such pins and adapted to serve for the appropriate connection of conductors.
  • One known type of such outlet equipment comprises essentially at least one pin composed of two parts and embedded in an insulating member, an intermediate member providing a conducting connection between the said two parts and locked in the insulating member and in each part of the pin and a male connectin-g member at one end of which the electric cable which is to be electrically connected through the partition is xed by any suitable known means, the other end of the male connecting member being engaged by a tight frictional t with the corresponding pin part, each male member being surrounded by an insulating sleeve slidable elastically in the direction of the axis of the pin so as to lock said male member against the head of the pin part, thus sealing and securing the connection.
  • the invention which likewise utilises an insulating sup port and at least one conductor pin, is more particularly characterised by the fact that a conducting member is disposed in a milled recess or cavity, of substantially cooperating shape, provided in that socket of the insulating support in which the conductor pin is inserted by force, and projects at least on one face of said support, said conducting member having at least one point of permanent contact with the pin with which it is associated.
  • the conducting member has the form of a plate which is inserted in a longitudinal recess milled in the pin socket and contacts the pin and/or the intermediate member within the socket.
  • the invention is not limited to the utilisation of the above described pins and male connecting members.
  • the invention is in fact applicable to any connection device capable of effecting detachable locking of the end of an electric wire or cable on a pin or other conducting sheath accommodated inside an insulating support or plate.
  • the invention enables an insulating assembly to .be produced which contains a plurality of conducting pins and on at least one face of which insulating assembly conducting members associated with the pins project. Nevertheless, it is possible to provide insulating supports in which the pins are only partly associated with conducting members.
  • the purpose of such members is to enable conductors to be connected as required, because by connecting the projecting parts of certain determined mem-bers or plates it is possible to shunt the corresponding conductor passages. In order to connect these projecting parts it is possible to make use of any suitable means, and in particular to use conducting plates, clips, or other similar conducting members.
  • the plate or support according to the invention may also be disposed inside a casing, the inlet and outlet for the conductors being provided on the casing.
  • FIGURE 1 shows a plan view of an insulating plate with a certain number of pins according tot the invention
  • FIGURE 2 is a section along the line II-II in FIG- URE 1;
  • FIGURE 3 is a section along the line III-III in FIG- URE 2.
  • the plate illustrated in the drawings. is composed essentially of an insulating support 1 in which conductor pins 8, 9 and 8', 9y are accommodated.
  • the support 1 is here formed of two parts 1a and 1b disposed one on each side of a plate 1c, the resulting assembly bein-g fastened by two end bolts or rivets Z and 3, with the interposition of rigid packings 4 and 5.
  • Holes 64 and 7 drilled at each end of the plate enable the connector constructed in this manner to be fastened on any suitable casing or board.
  • the pins comprise two identical members for example 8, 9 of a thin conducting material, which are split longitudinally at 10, 11 over part of their length and thus have a certain elasticity.
  • Each of the pins LS, 9 has a recessed internal clearance 12, 13 of spherical or oval shape, in which the corresponding outer bearing surface 14a, 15a of a male connecting member 14, 15 is engaged.
  • the mounting of such male members 14, 15, etc., is illustrated in FIGURE 2, this arrangement eiecting the detachable locking and fixing, respectively, on the pins 8, 9 of electric cables or wires at 16, 17 etc.
  • the hollow end parts of the pin members 8, 9 which are mounted in alignment with one another are connected electrically by intervening metal parts 18, 19.
  • metal parts or members 20 as shown in FIGURE 3 are associated with all or part of the pins 8, 9 and in the eX- ample illustrated are in the form of plates inserted in a milled recess 20a of longitudinal cooperating shape, provided in the socket 8a, 9a in which the pins 8, 9 are inserted by force.
  • these plates 20 On at least one face of the support, these plates 20 have projecting parts 21 which can be connected together by any electrical connection means, not illustrated, in order to enable the pins and corresponding conductors to be shunted as desired.
  • each male conducting member 14, 15 is a conducting stem forming a component of a connector unit CU.
  • a lirst sleeve 22 is slidably mounted on the stem 15 and has an inner end engageable with the end part of the pin 9 when the free end of the stem 15 is inserted into the pin.
  • the sleeve 22 is formed with an external ilange 22a lying Within a second sleeve 23 which is slidable on the stem 15 relatively to the ⁇ rst sleeve 22.
  • the inner endl of the sleeve 23 has an inturned flange 23a engageable with the external flange 22a on the sleeve 22, and the outer end of the second sleeve 23 has an inturned flange 23h engageable with an external llange 15b on the stem 15.
  • a compression spring 24 is interposed between the external flange 15a on the stem 15 and the first sleeve 22 for urging the latter longitudinally of the stem 1S toward the free end of the latter and into contact with the end of the hollow pin 9.
  • the connecting of the unit CU to the pin 9' may be effected by inserting the stern 15 into the pin 9 while grasping either the stem 15 itself or the second sleeve 23. In either case, the bearing surface a on the stem 15 will be inserted into the clearance 13 in the pin 9', and the inner end of the first sleeve 22 will be forced into spring loaded contact with the outer or exposed end of the pin 9'.
  • the cooperating anges 22a and 23a at the outer end of the first sleeve 22 and the inner end of the second sleeve 23 limit movement of the sleeve 22 relative to the sleeve 23 toward the free end of the stem 9'; and the cooperating flanges 23h and 15b at the outer end of the sleeve 23 and on the stem 15 limit move ment of the sleeve 23 relative to the stem 15 toward the free end of the latter.
  • a tapered female internal surface at the inner end of the sleeve 22 cooperates with a correspondingly tapered male outer surface at the exposed end of the hollow split pin 9 for clamping the pin end to the stem with the bearing surface 15a on the stem firmly held in the clearance 13 in the pin.
  • the support plate illustrated in the drawings has two parallel rows of pins 8-8, 9-9', regularly spaced apart.
  • a corresponding member of plates -20 is associated with the pins and their connecting parts 21-21 constitute two parallel lines permitting easy shuntin-g of the corresponding conductors.
