Definitions
- the present invention relates to an electrical contact member for the connection of electrical connection terminals to a printed circuit.
- this connection is achieved by depositing a cream conductive at the location where the terminal crosses the circuit, in contact with a electrically conductive track.
- the cream is then heated by micro-flame or by hot air, which causes it to melt and then harden on cooling.
- the present invention aims to overcome these drawbacks.
- said faces opposite are the large faces of the parallelepiped.
- At least one of said extensions is welded to a conductive track of said printed circuit.
- the main advantage of the invention resides in the fact that the contact according to the invention can be easily inserted into the hole provided for this effect, then crimped and finally welded to the wave at the same time as the components mounted on the printed circuit.
- the crimping and welding are carried out at the same time for all the contact members of the circuit. Then the terminal is engaged in the central space and the connection is simply done by elastic dry contact.
- the contact member 1 is made in one piece of strip metallic, for example of the order of 0.2 mm thick.
- It is essentially formed by a parallelepipedic body 2 delimited by two small end faces 3 and 3 ', and two large longitudinal faces 4 and 4'.
- the height h of the body 2 is slightly less than the thickness e of the printed circuit 5 for which the member 1 is intended.
- the large faces 4 and 4 'of the body 2 are not planar, but are gradually move towards each other upwards, in their parts longitudinally median, 6 and 6 'respectively. Each of these faces thus forms a sort of vault whose concavity is oriented towards the outside of the body 2.
- each large face Along the lower edge of each large face, a projection longitudinal is cut and folded substantially perpendicular to this face towards the outside of the body, to form a stop flap 7. We'll see below the usefulness of these flaps.
- a crimping lug 8 allows the mounting of the member 1 on the circuit printed 5.
- the member 1 is introduced from below into a hole 9 drilled in circuit 5, until the flap 7 abuts against the lower face 10 of the circuit.
- the ends of the legs 8, which protrude the upper face 11 of the circuit, are then folded against this face of so as to crimp the member 1 into the hole 9. It will be observed that, in the case present, the tabs 8 are folded over a conductive track 12 of the circuit 5.
- This mounting of the members 1 on the circuit 5 is carried out in the context of the installation of electronic components on this circuit.
- a cache 13 is then introduced into the central space of the member 1 so that its end surface 14 is flush with surface 11 of the circuit.
- the printed circuit 5 thus equipped is passed to the welding machine to wave to weld components and parts 1.
- the cover prevents the rise of molten metal in hole 9.
- Figures 2 and 3 show a terminal 16 engaged in a member of connection according to the invention.
- the terminal elastically spreads the arch parts 6 and 6 'of faces 4 and 4'. Because the end portions of these faces are blocked longitudinally and pressing against the sides of hole 9, it produces an arching of the arch parts 6 and 6 ', which ensures contact closes between the terminal and the connecting member.
