Abstract

A connection is made between a flexible conductor circuit 4 and a rigid conductor circuit 1, without the use of additional components. Thus, the rigid circuit 1 is provided, transverse to its conductors 2 to be connected, with a slot 5 of a length at least equal to the width of a portion of the flexible circuit 4 which is folded in two and introduced into the slot S. The connection between the conductor 2 of the rigid circuit and the cooperating conductors 3 of the flexible circuit is then ensured by spots of solder 7. <IMAGE>

Description

SPECIFICATION Connection between flexible and rigid conductor circuits This invention relates to a connection between a flexible conductor circuit and a rigid conductor circuit.
Various devices have been proposed for connecting the conductors of a flexible circuit to those of a rigid circuit. These devices use, for example, connecting pieces of a pressure type having resilient fingers equal in number to the number of contact points, which pieces may or may not have conductor elements.
In accordance with this invention there is provided a connection between a flexible conductor circuit and a rigid conductor circuit, wherein the rigid circuit is provided with a slot, transverse to at least one conductor. of the rigid circuit to be connected, the flexible circuit being folded in two and introduced into said aperture. Thus, the use of accessory connecting pieces is avoided, and the mounting and connection of the two circuits may be effected at the same time as those of the other components. Hence a great simplification in this type of connection is afforded.
Embodiments of this invention will now be described, by way of examples only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a flexible circuit and a rigid circuit assembled together; Figure 2 is a section through a modified assembly; Figure 3 is a plan view of modified flexible and rigid circuits prior to assembly together; and Figure 4 is a section of an assembly of the circuits of Fig. 3.
In Fig. 1, a rigid circuit 1 comprises conductors 2 disposed on one of its faces and which have to be connected to conductors 3 disposed on one of the faces of a flexible circuit 4. The rigid circuit 1 is provided with an aperture 5 of a length at least equal to the width of the flexible circuit 4, at right angles to the conductors 2. The flexible circuit is folded in two and the fold 6 thus obtained is introduced into the aperture 5 in the rigid circuit, the width of which should be such that it permits this introduction while ensuring a sufficient pressure on the two sides of the fold 6 to maintain the assembly. Each conductor 3 is thus disposed facing the conductor 2 with which it cooperates and perpendicular to this. The connection is then ensured by a spot of solder 7.This solder may be effected "at random" at the same time as that of the other electronic components which have to be assembled on the rigid circuit 1.
One or more of the conductors of the rigid circuit 1 may extend at both sides of the aperture 5 (Fig. 2). The connection of such a conductor 8 to the cooperating conductor 3 of the flexible circuit 4 may then be ensured by two spots of solder 9 and 10 deposited at each side of the fold 6.
A modification permitting a better centring and a better positioning of the flexible circuit 4 in the aperture in the rigid circuit, consists in forming a notch 11 (Fig. 3) on the edges of said flexible circuit, in the portion to be folded. The folding of said portion, on the axis XY, thus defines (Fig. 4) a stop 12 which comes to bear under the edges of the rigid circuit 1 after introduction into the aperture 5 and determines in a precise manner the height of the fold 6. The improvement in the centring is ensured by a slot 1 3 formed in the flexible circuit 4 and which cooperated with a bridge 14 of the same width, formed across the slot 5 of the rigid circuit, said bridge being accommodated, at the moment of assembly, in said slot 1 3 (Fig. 4).This latter improvement is independent of the first and may be provided in all embodiments.
It will be seen that by the assemblies which have been described, a connection is formed in an extremely simple and rapid manner and may be formed at the same time as the mounting of the components of the rigid circuit, which avoids additional manipulation.
1. A connection between a flexible conductor circuit and a rigid conductor circuit, wherein the rigid circuit is provided with a slot, transverse to at least one conductor of the rigid circuit to be connected, the flexible circuit being folded in two and introduced into said aperture.
2. A connection as claimed in claim 1, wherein the cooperating conductors of the two circuits are disposed perpendicularly facing one another and are connected by at least one spot of solder.
3. A connection as claimed in claim 2, wherein at least one conductor disposed on the rigid circuit extends from one side to the other of said slot and a spot of solder is applied to the cooperating conductors of the flexible and rigid circuits at each side of the fold in said flexible circuit.
4. A connection as claimed in any preceding claim, wherein the edges of the flexible circuit are formed in the portion to be folded, with a notch of a length equal to double the height of the fold in said flexible circuit.
5. A connection as claimed in any preceding claim, wherein the flexible circuit comprises a slot cooperating with a bridge, of corresponding width, formed in the slot formed in said rigid circuit.
6. A connection between a flexible conductor circuit and a rigid conductor circuit, substantially as herein described with reference to Figs. 1 and 2 or Figs. 3 and 4 of the accompanying drawings.
