Definitions

  • the present invention relates to a socket, in particular for the production of electric garlands, comprising a substantially cylindrical outer sheath and open at its two ends, a substantially cylindrical core comprising at least two notches for housing two electrical connectors, and a door -lamp, the core and the connectors being located inside the outer sheath, each connector comprising at one end means for its attachment to a conductive wire and at the other end, means for its electrical connection to the holder- lamp.
  • Such a socket is known in particular from document GB-A-2 094 564, and comprises a core having notches 311C formed from the upper front face of the core and into which the connectors 311 A, 311 B are slid from above.
  • a clip 41 is provided for holding the wires 13A, 13B by pinching. Such pinching does not guarantee absolute immobilization of the wires.
  • the connectors can move axially inside the socket. As a result, short circuits are likely to occur.
  • the object of the invention is to propose a socket of the type defined at the start of the description, which guarantees absolute positioning of the connectors.
  • said notches are formed on the outer surface of the core and each connector comprises means for blocking it relative to the core, which cooperate with a specific notch formed on the outer surface of the core.
  • said blocking means are arranged between said fixing means and said connection means, and extend laterally on either side of the connector.
  • Another object of the invention is to provide an electrical connector arranged so that the attachment of a male part or pin of a lamp holder on it, is ensured even in the event of large tolerances, so that the pressure of contact between connector and pin is independent of the insulating materials used to make the socket.
  • the means for connecting each connector to the lamp holder comprise a cylindrical sleeve made up of two substantially semi-cylindrical branches separated from each other by a slot, this sleeve receiving a pin of corresponding shape provided on the holder. -lamp.
  • said means for fixing each connector to a conductive wire comprise a crimping ferrule.
  • the invention also relates to an electric garland equipped with at least one socket as defined above.
  • a socket according to the present invention designated by the reference 1 as a whole, comprises an outer sheath 2, in which is located a core 3 and at least two electrical connectors 4 and 5.
  • a lamp holder 6 can be mounted on such a socket 1.
  • the outer sheath 2 is substantially cylindrical and open at its two ends.
  • the lower part of this sheath 2 can be frustoconical, that is to say narrowing in the direction of the lower end for reasons which are explained below.
  • the core 3 is also substantially cylindrical and of a diameter at most equal to that of the sheath 2 in which it is normally located. It is held in position in the sheath 2 thanks to the frustoconical lower part of the latter, according to the present embodiment. It has on its periphery at least two notches 7 and 8 in which the electrical connectors 4 and 5 are arranged respectively.
  • Each electrical connector 4, 5 which is produced for example from a metal foil in particular by cutting and winding, consists of a vertical part 28 comprising at its upper end a cylindrical sleeve 9 and at least one crimping ferrule at its lower end.
  • the cylindrical sleeve 9 consists of two branches 10 and 11 which are substantially semi-cylindrical and separated from each other by a slot 12.
  • This electrical connector comprises, according to the present embodiment, two ferrules 13 and 14, at its lower end, arranged one at- below each other.
  • the ferrule 13, or lower ferrule is crimped around the insulating part 15 of a conductive wire 16 and the ferrule 14, or upper ferrule, is crimped around the conductive part 17 of this same conductive wire 16.
  • Each electrical connector comprises also two locking elements 18 and 19 symmetrically opposite.
  • the core 3 comprises at least two notches 7 and 8 in which the electrical connectors are arranged: these notches therefore more or less conform to the shape of these connectors.
  • Each notch consists of an upper cutout 20 in which the sleeve 9 is located, which is substantially higher and wider than it and which is open at its upper part, a lower cutout 21 in which is located the lower part of the connector comprising the two ferrules 13 and 14, and an intermediate cutout 22 for housing the locking elements 18 and 19.
  • the electrical cables must be crimped onto each electrical connector using their ferrules 13 and 14, thread them into the outer sheath 2, place each connector in position in its respective notch provided in the core 3, press the assembly into the sheath 2 until this assembly is blocked, and finally introduce the lamp holder 6 fitted with its lamp 30.
  • Means may be provided for locking the core 3 in the sheath 2, as shown in particular in FIG. 4.
  • a boss 23 is located towards the lower end of the sheath 2, cooperating with a groove 24 located at the bottom of the core 3.
  • the present invention offers in particular the advantage of allowing pre-tightening on automatic machine of the electrical connectors on the cables.
  • the tightness of the passage of the cables in the sheath is very satisfactorily ensured by the very fact that they are clamped in the notches provided in the core to immobilize the parts during assembly. and compress at the end of assembly.
  • the tensile effects on the cable are therefore taken up both by the connector and by the assembly: there follows a strong improvement in the tensile strength which is exerted in the direction of blocking of the core in the outer sheath .
  • the electrical connection which is established between an electrical connector 4 and the corresponding pin 25 of the lamp holder 6, is independent of the parts constituting the socket 1: in fact the sleeve 4 can be deform elastically and freely. As for the locking elements 18 and 19 located in the cutout 22, they provide better resistance to tearing.
  • Such sockets 1, fitted with lamps 30, are used in particular to constitute electric garlands.
  • garlands can include ordinary and / or flashing lamps, these sockets should be fitted with polarizing pins.
  • each outer sheath 2 a lateral notch 26 in which engages a lug 27 of the same shape which is provided with the flashing lamp holder.
  • two lateral notches are provided which cooperate with the two lugs which are provided with the non-flashing lamp holder: thus a non-flashing lamp holder cannot be fit only in a socket provided for him.
  • the two indentations of the sleeve are preferably located symmetrically, just like the two pins of the non-flashing lamp holder.
  • the core 3 is of a length such that once locked in the outer sheath 2, its apex is flush with the upper end of this sheath and its lower end protrudes from that of the sheath 2.
  • This is particularly advantageous insofar as this lower end may include a hole 29 through which a ring (not shown) can be passed: this makes it possible to suspend the socket 1 provided with its lamp 30 without introducing mechanical stress into the sheath of the conducting wires 16.
  • a socket structure according to the present invention therefore makes it possible to obtain a very good elastic connection between each electrical connector and the corresponding metal pin or the corresponding conductive wire disposed on an insulating pin as there is a lamp holder for such a socket.
  • this wire 25 is advantageously disposed opposite the slot 12 of the cylindrical sleeve 9 thanks to a specific notch formed in the insulating pin.
  • Such a socket comprises an outer sheath 102, in which is located a core 103 as well as at least two electrical connectors 104 and 105, and a lamp holder 106.
  • This outer sheath 102 is substantially cylindrical and open at its two ends. Its lower part can be frustoconical.
  • the core 103 is also substantially cylindrical and of a diameter at most equal to the inside diameter of the sheath 102 in which it is located. It is held in position in this sheath thanks to the frustoconical lower part thereof.
  • it comprises two vertical pins, 140 and 141, arranged symmetrically at its upper part, which cooperate with two notches arranged symmetrically at the upper part of the sheath 102.
  • the core 103 has on its periphery at least two notches 107 and 108 in which the electrical connectors 104 and 105 are arranged, respectively.
  • Each electrical connector 104, 105 which is produced for example from a metal foil that in particular by cutting and winding, consists of a vertical part 128 comprising at its upper end a cylindrical sleeve 109 and at least one crimping ferrule at its lower end.
  • the cylindrical sleeve 109 consists of two branches 110 and 111 which are substantially semi-cylindrical and separated from each other by a slot 112.
  • This electrical connector comprises, according to the present embodiment, two ferrules 113 and 114, at its lower end, arranged one below the other.
  • the ferrule 113, or lower ferrule is crimped around the insulating part 115 of a conductive wire 116 and the ferrule 114, or upper ferrule, is crimped around the conductive part 117 of this same conductive wire 116.
  • Each electrical connector comprises also two locking elements 118 and 119 symmetrically opposite.
  • the core 103 comprises at least two notches 107 and 108 in which the electrical connectors are arranged: these notches therefore more or less conform to the shape of these connectors.
  • Each notch consists of an upper cutout 120 in which the sleeve 109 is located, as indicated by the arrows F, and F 2 , which is substantially higher and wider than it and which is open at its upper part, d a lower cutout 121 in which the lower part of the connector including the two ferrules 113 and 114 is located, and an intermediate cutout 122 for housing the locking elements 118 and 119.
  • the means for locking the core 103 in the sheath 102 are constituted by two lugs 142 located at the base of the core 103: when the latter is pressed into the sheath 102, these lugs 142 by cooperating with the lower edge of this sheath prohibit any rise in the core 102. Furthermore, the upper lugs 140 and 141 by cooperating with their respective notches prevent any further depression of the core 103.
  • the core 103 is of a length such that once blocked in the outer sheath 102, its apex is flush with the upper end of this sheath and its lower end exceeds that of the sheath 102
  • the core 103 at its upper end and in the same plane as the lugs 140, 141, comprises a cloth 145 of electrical insulation which has the main role of increasing the distance in the air and the line of flight between the two connectors 104, 105.
  • This fabric also constitutes a stop against any accidental contact at the bottom of the socket and prevents rotation of the lamp holder 106 by means of the recess 146 which cooperates with it, in order to avoid introducing transverse stresses in the connectors and the lamp holder in the event of improper handling.
  • connection which is established between an electrical connector 104 and the corresponding pin 125 of the lamp holder 106 is independent of the parts constituting the socket, as in the previous embodiment.
  • Electric strings made up of such sockets may include ordinary and / or flashing lamps 130, these sockets should be fitted with polarizing devices.
  • each outer sheath 102 there is provided, for example on each outer sheath 102, a lateral notch 126 in which engages a lug 127 of the same shape which is provided with the flashing lamp holder.
  • a lateral notch 126 in which engages a lug 127 of the same shape which is provided with the flashing lamp holder.
  • two lateral notches are provided which cooperate with the two lugs which are provided with the non-flashing lamp holder: thus a non-flashing lamp holder cannot be fit only in a socket provided for him.
  • the two notches of the socket are preferably located symmetrically, just like the two pins of the non-flashing lamp holder.
