Definitions
- the invention relates to a one-piece electrical contact terminal, made of cut and folded sheet metal, intended to receive a contact blade. It relates more particularly to a terminal of the type comprising a front body in the form of a cage having an adjoining bottom on two sides each having an internal flank connected laterally to an external flank by a 180 ° fold and having a door portion at the front false contact.
- Contact terminals of the type defined above are already known, which can be manufactured by cutting, folding and possibly rolling a strip in a much more economical manner than the low-cut terminals.
- the existing contacts made of cut and folded sheet metal have a certain number of drawbacks. If the parts constituting contact of the internal sides are initially in abutment against one another and oppose a high force to their spacing, which is favorable to the establishment of an electrical connection of good quality, the insertion force is important and there is a risk of incorrect introduction. The first drawback can become serious if a large number of contact terminals are provided in the same connector. If, on the contrary, the parts constituting the contact are initially separated, their support on the contact blade may in certain cases be insufficient to ensure a good electrical connection.
- each external flank has at the front a flap folded inwards around an edge transverse to the internal flank, retaining the front part of the internal flank. in bending preload in a position where it is out of contact with the other internal flank.
- the flap which can end very close to the closest areas, ensures the pre-guiding of the contact blade during its introduction.
- the distance between the contacts is constant regardless of the pressure exerted.
- the presence of a space between the contact zones makes it possible to deposit an electrolytic protective coating on them. Due to the initial separation of the contact areas, the insertion force of the contact blade is reduced.
- the invention also aims to provide a contact terminal having improved resistance to crushing so that the rear flap, if provided, does not need to come into abutment abutment against the opposite side, its role merely to avoid, when a sealant is poured into the connector, that the latter does not infiltrate the body of the terminal and subsequently interfere with the electrical connection.
- the two flanks on each side are folded at right angles in their bearing zone against each other, so that the 180 ° folds are face to face and in close proximity to one of the other. Under these conditions, if a crushing force is exerted on the terminal, these folds come to bear against one another and offer high resistance to deformation.
- Terminal 10 whose final constitution is shown in Figures 1 and 3 to 7, made from a side of the kind shown in Figure 2, is intended to be inserted in a connector whose general constitution may be conventional.
- Terminal 10 is in one piece. It can be viewed as having a front body intended to receive a male contact blade 12 and a rear barrel to be crimped 14 of which only a fraction is shown in FIGS. 2 and 4.
- This barrel comprises two sets of tongues 16 and 18, respectively intended to be crimped on the core and on the sheath of an electric wire 20 ( Figure 3).
- the body of the terminal 10 has a cage shape having a bottom 22 and two sides 24. Each side 24 is double. It comprises an external flank 26 and an internal flank 28. Each external flank 26 is produced by 90 ° folding of the original blank along one of the lines 30 indicated in phantom in Figure 2.
- the internal flank 28 is connected to the external flank 26 by a 180 ° fold along the edge indicated at 32 on the FIG. 2.
- the assembly of the two sides 26 and 28 has a fold at right angles along the lines designated by 34 in FIG. 2.
- the original blank has notches 36 such that each internal flank 28 is connected to the corresponding external flank 26 only in its rear part.
- the front part of each internal flank thus constitutes an elastic contact for bearing on the blade 12.
- each internal flank 28 is divided by a slot 38 over a part of its length from the free end, which allows more regular support.
- this splitting is not essential.
- One or both of the contacts could have no slot 38. Conversely, it would be possible to provide more than one slot in each contact.
- the part of the sides 26 and 28 close to the 180 ° fold constitutes a cage ceiling.
- the cutting of the original blank leaves tabs 40 bearing abutment against one another and constituting a continuous ceiling in the cantilevered area of the internal flanks 28, while the 180 ° folds remain separated by a gap 42.
- This solution may be advantageous when the terminal is intended to be placed in a connector where the seal is ensured by penetration of the connector insulator inside the terminal.
- the cutout may be such that the folds at 180 ° are in contact with each other as indicated in dashes in FIG. 8. The latter solution limits the risk of snagging terminals between them when grouped in bundles or in bulk and ensures complete protection of the contacts.
- One of the internal sides 28 is extended at the rear by a flap 44 folded at 90 ° ( Figures 2 and 6) and coming to bear against the other internal side.
- the role of this component is essentially to avoid the infiltration of the overmolding product used to seal the rear of a connector in which the terminal is placed. However, this component can also participate in resistance to crushing.
- Each internal flank 28 advantageously has a shape of the kind shown in FIG. 6.
- the cantilever part, forming electrical contact represents a little more than half of the total length of the flank 28 and it is shaped so as to present an inward camber and a thickened elbow directed towards the other flank, in the immediate vicinity of the free end.
- the elastic force due to the bending of the contact and tending to bring two contacts close together is absorbed by a flap 46 of the corresponding external flank 26, folded back.
- the fold of the flaps is in front of the end edges of the bottom and the ceiling of the cage and is rounded, which facilitates the introduction of the terminal in an insulator and limits the risk of deterioration of the last.
- the edges of the bottom and ceiling can be softened.
- the corners formed by the sides and the ceiling at the back of the body can be broken during manufacture.
- the external flanks 26 may have cavities 48 of shallow depth (for example representing 20% of the thickness of the flank) opposite the root of each contact of an internal blank 28 and opposite the end part retained by the flap 46.
- this finger is constituted by an elongated tongue 52 formed during the molding of the insulation, having a lug directed inwards and capable of engaging in the window 50. Because the tongue extends in front of the lug, it is possible to unlock the connector by pushing a tube through the front passage 54 of the insulation (delimited by an annular lip having a gap allowing the mounting of the tongue 52), this tube slipping between the side of the terminal and the tab. Due to the symmetrical location of the two windows 50, the terminal can occupy one or the other of two symmetrical positions in the cell of the insulation.
- the manufacture is generally carried out by cutting and folding strips of copper alloy having a thickness of 0.3 to 0.4 mm.
- the strip is cut to give rise to successive blanks of the kind shown in FIG. 2, connected together by a connecting strip 56.
- the fold lines, indicated by dashed lines in FIG. 2 can be marked with the press.
- the contacts are shaped by bending and striking intended forming the thickened outward bulge constituting the support zone and the flaps 46 are formed. As shown in FIG.
- the thickness of the contacts in the free end part and to give the assembly, constituted by the flaps and this free end part of the contacts, a slope, for example of approximately 15 °, which facilitates the introduction of the male contact blade.
- the recesses 48 can also be formed by striking, before forming the contacts and folding the blank.
- the invention is not limited to the particular embodiments which have been shown and described by way of examples. It is susceptible to numerous variations. For example, it is possible to form a terminal whose faces are not exactly parallel but have a slope; a notch (in phantom in Figure 4) allowing the passage of the male blade at an angle, which is required for certain sealing embodiments, intended to receive a sealing tongue can be provided at the front of the contact ceiling.
