Electrical connections. The member comprises a sole 1 with legs 2 and 10 provided with extensions 4 and 17 respectively, the latter having slots 5-14 and tongues 7 and 16 cooperating with corresponding recesses 21, 22 of the legs 2 and 10, the extensions being locked by tabs 9 and 13.

Description

The present invention aims at an electrical connection member of the type

  having a male or a female part

  intended to cooperate with a corresponding male or female part

  and one end of which is provided with a connection member to an electrical conductor.

  The invention also relates to con-

  so-called hermaphrodite nexion, in which there is provided a part which cooperates with an identical part of another

  connector that is turned double-sided.

  The electrical connection member is generally

  consisting of two pairs of legs, one pair being

  intended to enclose a bare part of the electrical conductor

  and the second to enclose said conductor and its sheath.

  It is therefore necessary to conduct a first stripping operation of the driver, then to a second operation of setting up the driver and finally to an operation

  in which the legs are folded

  killed on the driver. These operations being complex, it has been imagined to make connection members which ensure, on the one hand, the stripping of the conductor and, on the other hand,

  the fixing of the latter, such connecting devices

  are known as "connection

with insulation displacement ".

  The invention relates to a displacement connection

insulation.

  Connections of this type generally include

  a paw with a slot into which we introduce

  the driver, the width of the slot being such that the

  lant is sheared and thus the strands of said conductor cooperating with the edges of the slot provide the electrical connection. Such a provision has not always been

  proved to be very effective and one of the purposes of the present invention.

  tion is to make an insulation displacement connection

  providing great security for connecting the con-

  conductor, the electrical connection and the fixing of

tor.

  The electrical connection member, according to the invention

  is of the type made from a metal strip good conductor of electricity cut and suitable-

  bent, from a sole, on the one hand, to pre-

  sensing a male, female or hermaphrodite electrical contact member (A) and, on the other hand, an electrical connection member (B) with a conductor and an insulation displacement type, and is characterized in that the sole comprises laterally on one side a first tab intended to extend perpendicularly to said sole, an edge of this tab turned towards the connecting member A being provided with an extension intended to be folded to extend, d ' a part,

  perpendicular to the sole and, on the other hand,

  to the tab, said extension having an open slot and flared on the side of the free end, while its free lateral edge is provided with a bar, the tab on the side opposite the extension comprising a recess and a locking tab, said soleplate being further provided laterally, and on the opposite side to the first leg of a second leg intended to extend perpendicularly to the soleplate, an edge of this second leg turned on the opposite side to the connecting member A being provided with an extension intended to be folded to extend

  perpendicular to the sole, on the one hand, and perpendicular

  in particular to the second leg, on the other hand, the said

  lengthwise having an open and flared slot on the free end side, while its free lateral edge is provided with a bar, the second tab, on the side opposite the extension having a recess and a locking tongue, the tongue of the extension the first tab being inserted into the recess of the second tab, the locking tab of the second tab being folded against the said extension, while the tongue of the extension of the second tab is inserted into the recess of the first the locking tab of the latter being folded against the

  extension of said second leg.

  According to a detail feature, one of the slits of one of the two extensions is wider than that of the other extension. Thus we obtain a better driver behavior and we avoid that the lips

  slits of the extensions are too far apart

  to interfere with the electrical connection of the said fixa-

the driver.

  Preferably, the widest slot is the

  split from that of the extension of the second leg.

  In order to avoid a permanent stress on the driver when put in place the bottom of the slots

ends with a flourishing.

  Finally, according to a last characteristic, the tongues of the extensions of the first and second legs are extended so as to be folded down.

  against the outer face of the corresponding legs.

  The invention will now be described in more detail with reference to embodiments

  particulars given as examples only and

  in the accompanying drawings, in which: FIG. 1 is a plan view of a sheet blank

  cut to obtain a contact element, according to the invention.

tion.

  Figure 2 and Figure 3 are perspective views.

  showing the folding of the connecting part with

the conducting wire.

  Figure 4 shows in perspective a male tongue. Figure 5 shows in perspective an element of

female contact.

  Figure 6 is a perspective view of a

  embodiment of the invention.

  In the various figures, there is shown an electrical contact member intended to be placed in a

  corresponding channel of an insulating housing. This contact elec-

  can be male, female or hermaphrodite.

  The electrical contact member is made

  from a metal band which is a good conductor of electricity

  cited and having some elasticity.

  The strip is cut to present a part A intended to be shaped to constitute a body of

  male, female or hermaphrodite contact and a part B con-

  the connecting part with an electrical conductor

  this part B forming a connecting member

with insulation displacement.

  Part A may be of a known type

  will not be described here in detail. Part B of connection

  with the wire is cut to show

  a sole 1 whose extension will be conformed to

  stagger the male, female or hermaphrodite contact member.

  Laterally, on one side the sole 1 comprises a first leg 2 which is intended to be folded along a line

  3 to extend perpendicular to the sole 1.

  The first leg 2 comprises an extension 4 intended to be folded along a line 8 to extend perpendicularly, on the one hand, to the leg 2 and, on the other hand, to the sole 1. The extension 4 comprises a slot 5 which has a portion 5a whose lips are parallel

  and a portion 5b flared to a free edge 6 of said pro-

long 4.

  The extension 4 in the vicinity of the free edge

  6 and on a free edge 20 comprises a bar 7.

  The tab 2, along its edge opposite line 8 is extended by a locking tab

  9 intended to be folded along a line 27.

  The sole 1, on the opposite side to the leg 2,

  carries a second leg 10 which on one side

  13 and on the opposite side an extension

17.

  The second leg 10 is intended to be folded along a line 18 to extend perpendicular to the sole 1, the extension 17 being folded along a line 11 to extend, on the one hand, perpendicular to the sole 1 and, on the other hand, perpendicular to the

leg 10.

  The extension 17 has a slot 14 which has a portion 14a whose lips are parallel

  and a flared portion 14b opening on an edge 26.

  The locking tab 13 is intended to be folded along a line 12 and the free edge 19

  adjacent to edge 26 of extension 17 has a bar

rette 16.

  In the vicinity of the locking tab

  13 the leg 10 has a step 21, a pick-up

  22 being provided in the vicinity of the green tongue.

rust 9 located on the leg 2.

  Slot 14 in part 14a is slightly

  wider than the part 5a of the slot 5.

  As seen in Figures 2 and 3, the legs

  2 and 10 are folded to extend parallel and allow

  pendicularly to the sole 1, then the extension 4 is folded so that the bar 7 comes to bear against the recess 21, the extension 17 is also folded

  for the bar 16 to come to bear against the

  22, the locking tongues 9 and 13 being folded back, respectively against the extensions 17 and 4.

  Figure 4 shows an example of a con-

  male, the sole 1 being extended to form a

  element 24 intended to cooperate with a female body cor-

  respondent, for example an organ such as that shown

  in Figure 5 and bearing the reference 25.

  The electrical connection part B allows

  to perform simultaneously and without having to strip the con-

  conductor, the electrical connection and the fixing of

  tor. The latter is engaged in the slots 5 and 14, this engagement being facilitated by the flared portions 5b and 14b. The slot 5 cuts the insulating sheath of the driver

  and deforms the section of it, without deeply

  said conductor, so that the electrical connection is made, while the slot 14 intersects said insulating sheath to the conductor for securing

  the latter and, at the same time also the electrical contact.

  In Figure 6, there is shown a variant of the invention. In this figure, the same references as those of the preceding figures have been used to designate the corresponding members, but assigned the letter

IIC! 1.

  The bars 7c and 16c are, in this variant, extended by parts 7d and 16d respectively which

  are intended to be folded against the corresponding faces

  2nd legs and O10c. Thus, we strengthen the liason

  between the legs 2c and 10c and the extensions 4c and 17c.

  Slots 5c and 14c can also be

  undermine by 5d and 14d blooming in order to avoid a

  permanent stress on the driver.

  Of course, the invention is not limited to the embodiments that have just been described and shown. We can make many changes

  without departing from the scope of the invention.
