Definitions

  • the present invention relates to an improved electrical connector which can be used in particular for producing lamp holder sockets for electric strings.
  • a socket is constituted by an electrical connector which generally comprises a cylindrical insulating part and two female conductive elements each located in a cell formed in this insulating part.
  • the decoration for example, of fir trees or shop windows for the end of year celebrations notably calls for the use of electric garlands.
  • This material now replaces the traditional candles whose use was the cause of many accidents: fires, burned children, etc.
  • the use of electric strings nevertheless has some drawbacks such as short circuits which can lead to the same accidents as candles, or heating at the level of the lamp holder sockets which can become so intense that it causes a short circuit. .
  • one of the objects of the present invention is an electrical connector which does not have the drawbacks mentioned above.
  • Another object of the invention is an electrical connector in which the fixing of the male parts or pins in the elements located in the cells can be ensured even in the event of large tolerances.
  • An object of the present invention is an electrical connector which has elasticity and conductivity qualities which do not interfere with those of insulation.
  • an electrical connector which comprises at least one conductive element which is arranged in a cell formed in an electrical insulator, which comprises at one end at least one crimping ferrule; this cell comprises two cylindrical parts, an upper and a lower, located on either side of an intermediate part whose diameter is less than each of these two parts and is at least equal to the width of the conductive element, and this element conductor further comprising at its other end a cylindrical sleeve and two elastic tabs which are located between these two ends and which cooperate with a shoulder formed between the intermediate part and the lower part of the cell.
  • this cylindrical sleeve is constituted by two substantially semi-cylindrical branches separated from one another by a slot.
  • one of these branches has at its base a lug which extends inwardly relative to the conductive element and which is substantially perpendicular thereto.
  • the upper part of the cell has over its entire height a vertical groove in which this pin can slide.
  • this lug comes into contact with a shoulder determined by the intermediate part and the upper part.
  • cylindrical sleeve is not in contact with the walls of the upper part of the cell.
  • the conductive element comprises two crimping ferrules.
  • An application of the present invention consists in the production of lamp holder sockets in particular for electric strings comprising such connectors.
  • an electrical connector according to the present invention consists of a conductive element designated by the reference 1 which is located in a cell 2 formed in an electrical insulator 3.
  • This conductive element 1 which is produced for example from a metal sheet in particular by cutting and winding, comprises at its upper end a cylindrical sleeve 4 and at its lower end a first ferrule 5 for crimping.
  • the cylindrical sleeve 4 is constituted by two branches 6 and 7 substantially semi-cylindrical and separated from each other by a slot 8.
  • branch 6 in this embodiment has at its base a lug lateral 9 which extends outwards and which is substantially perpendicular thereto.
  • the conductive element 1 comprises a second crimping ferrule 10 situated a little above the first ferrule 5. These two ferrules are intended for fixing a conductive wire 11 the first ferrule 5 is crimped around the insulating part 12 of this wire and the second ferrule 10 around the conductive part 13 of this conductive wire 11.
  • the conductive element 1 comprises two elastic tabs 14 and 15 intended to move outward: that is to say that they form an angle with this element acute turned upwards.
  • the cell 2 formed in the insulator 3 it consists of three substantially cylindrical parts; an upper part 16 and a lower part 17 arranged on either side of an intermediate part 18 whose diameter is less than that of each of them. This therefore determines two shoulders 19 and 20 respectively between the upper part 16 and the intermediate part 18 and between the lower part 17 and the intermediate part 18.
  • the upper 16 and lower 17 parts have substantially the same diameter.
  • the diameter of the intermediate part 18 is greater than that of the conductive element 1.
  • the upper part 16 includes a vertical groove 21 over its entire height.
  • the implementation of the conductive element 1 in the cell 2 is carried out as follows
  • This element 1 is crimped, thanks to the ferrules 5 and 10, around the conductive wire 11 which has previously been threaded into the cell 2. Then this conductive element is pressed from top to bottom by sliding the lug 9 in the vertical groove 21, until the latter comes into contact with the shoulder 19.
  • the elastic tongues 14 and 15 are tightened against the element 1 when crossing the intermediate part 18 thanks to the shoulder 19. They move away from it after having crossed the shoulder 20, against which they take support if you want to remove the conductive element 1 from the socket 2.
  • the conductive element 1 can neither be pushed further into the cell 2 since the lug 9 abuts against the shoulder 19, nor be out of this cell 2 since the elastic tongues 14 and 15 bear against the shoulder 20.
  • the upper part 16 is of a diameter greater than that of the cylindrical sleeve 4, as described above, it will be noted that this cylindrical sleeve is not in contact with either the walls of this cylindrical part or the shoulder 19 except through lug 9.
  • Connectors according to the present invention can be used in particular for the constitution of lamp holder sockets for electric strings.
  • garlands may include ordinary lamp holders and / or flashing, it is necessary to provide these sockets with a polarizing device so that in an ordinary lamp holder can not mount a flashing lamp.
  • each flashing lamp holder socket in which engages a lug of the same shape which is fitted with the base of the flashing lamps.
  • an ordinary lamp holder socket has two notches, for example diametrically opposite, which cooperate with two lugs arranged in the same way on the base of ordinary lamps.
