Description

The present invention relates to a con-

  electrical connection such as those intended to receive a pin

  a relay, a contact of a fuse or even a circuit board.

  The invention also relates to a housing for receiving such a connection member. The present invention relates to organs of

  connection of the type consisting of a body made of a material good conduct-

  trice of electricity having, at one end, means for its connection to an electrical circuit that is to say IO pioyens allowing either the connection of a current wire or the attachment of the device on a printed circuit board, that is to say the production of a fuse box, etc., said body being folded to present a "U" section

  with one soul and two wings, each wing being provided with a

  I5 long folded to extend inside the body so

  to form an elastic clip for receiving the organ

to connect.

  In such connection members, provision is made for

  means that allow their attachment in an insulating housing.

  Generally, these means consist of tabs de-

  cut either in the bottom of the soul or at the ends of the wings opposite to those provided with extensions, the said

  tabs protruding outside the body. To put

  in place the connection device, the latter is engaged in a channel provided in the housing, which channel comprises a

  shoulder that is crossed by the tongue

  elastic formation thereof, the free end of said tongue abutting against the shoulder to oppose the withdrawal

  of the connection member when it is engaged.

  It has been found that such tongues have

  many disadvantages and that, in particular, they do not

  did not always serve. Indeed, they are often during different manipulations, deformed and the organ

  connection is not well maintained in the box.

  tier. In addition, each connection member must be made according to the thickness of the plug it must receive. Indeed

  it is very important that the extensions are not

  formed beyond a certain extent during the introduction

  of the plug, otherwise the electrical connection is not good

born.

  One of the aims of the present invention is to realize

  be a connecting member that overcomes the various disadvantages above. The connection member object of the present invention is of the type made of elastic material good conductor of

  electricity and consisting of a U-section body

  a core and two wings, said body being provided at one end with means for connecting it to an electric circuit,

  while at the other end, each wing

  I0 long folded to extend inside the body between said wings to form an elastic clip for

  to receive a plug of a connecting member such as a broach

  a relay, a contact of a fuse or even a circuit board, and is characterized in that each extension

  I5 is bent so as to have a convex part, the con-

  vexed being turned opposite each other so

  that each convex part co-operates with the convex part cor-

  respondent of the other extension, the free end of each

  an extension extending in the vicinity of the inner surface of the wing that extends and laterally having a lug protruding from the lateral surface of said wing that extends. With this arrangement, a connecting member is produced which is capable of receiving, while ensuring perfect contact, plugs of variable thickness and whose fixing means in the housing are not likely to be damaged, the fixing in said case being sure to be

always perfect.

  Preferably and according to a particular characteristic

  each lug is arranged to protrude along the free edge of the flange opposite the edge adjacent to

  blade. Thus the soul can have a relatively large height

  aunt which gives the connection member a better rigidity

  ity. According to yet another characteristic of detail, the bent part of each extension has at least one slot. So when introducing the card, each part determined by the slot acts as an independent part of

  so that the electrical connection is better.

  In order to facilitate the introduction of the connection member in the housing, while being certain that said member will be perfectly maintained in its housing, each lug forms with the edge of the extension which it is integral with the end side. of the body opposite to that provided with means for being connected to an electric circuit, an obtuse angle

  and on the other side, a right angle.

  The invention also relates to a housing intended to re-

  cevoir a connection member as defined above, said I0 box being of the type having a plastic body provided with at least one channel for receiving the body of

  connection, said channel having an opening at one end

  mity for the introduction of said member and at its other end a slot for the passage of the plug to connect, means I5 being provided to cooperate with corresponding members of the connection member to maintain it when it has been introduced into the channel, and being characterized in that said channel has on each of its faces intended to cooperate with the lateral surface of the wings, two parallel grooves, each groove having a shoulder turned towards the slot. With this arrangement, it is possible to engage in the channel the connecting member according to two angular positions.

  offset by 1800, which greatly facilitates assembly.

  Finally, the depth of each groove is less than the height of the lugs. Thus when the connection member is mounted in its casing, a slight pressure is applied

  on the ends of the pins so that the parts

  vexes extensions are held against each other.

  The invention will now be described in more detail with reference to particular embodiments given by way of example only and represented in the accompanying drawings. In these drawings Fig. I is a perspective view of a connection member according to the invention,
