Definitions

the invention concerns an electrical connection device especially suited for use in electric and electronic circuitry.
connections that are used in electronic control units for automobiles their construction is based on attempts to strike a balance between as miniaturised a design as possible against the possibility of supporting high density currents and thereby enabling them to carry as high a power as possible.
the female device basically consists of a main body B which acts as a base for a basically longitudinal, tubular collar C, whose walls form a socket D where the male contact device is plugged in by a sliding movement, not illustrated in this instance.
the tubular collar C includes a U-shaped profiled section E and a laminar body F, which is set parallel to the profiled section E and spaced apart from the facing sides Ea, Eb that define the actual profiled section E.
the tubular collar C and the main body B are made from a single piece produced by a boxed construction of blanked and bent sheet metal, where the laminar body F is a single body with the main body B and has a free end Fa.
the laminar body F acts as a encased ledge and flexes upwards by bending along a leverage line located on the main body B when the male device, as it is plugged in, presses against the ridge G.
the electrical contact is guaranteed by the elastic force exerted by laminar body F as ridge G presses against the male device after it has been plugged into the socket D.
Female electrical connection devices produced according to the construction described above when on the one hand offer the advantage of being easy to manufacture and being able to be produced in rather small sizes, on the other hand they have the inconvenience of not being able to develop a sufficiently high pressure against the male device that is plugged into them, at least not enough to allow the passage of intense currents. As a consequence these electrical connections cannot be used to carry high levels of electric power.
the female connection has one or more contact blades that have an end that is free to flex under the thrust of the male device as it is introduced.
Each blade in addition to its end being free to flex, is also bent with the outside curve set against the male device, improving its adherence and thereby guaranteeing greater mechanical stability in the connection and favouring the passage of electric current.
the flexible blades are basically equivalent to booms anchored at one end, so they are only capable of creating a somewhat limited contact pressure against the male device. Sometimes this pressure is increased by filling a stop bar over the blade at about halfway along its length, as can be seen in patent US 3 836 947A, which, by its rigidity, increases the recoil force of the flexible blade against the male device that is plugged in.
a stiffening wall is set above it made of a separate part to the body of the female connection, being held together by means of special snap-in clasps made in the edges.
This invention intends to overcome all of said limitations.
the first scope of the invention is to produce a female electrical connection device that develops, against the male device that is plugged into it, a greater contact pressure than that achieved by known types of female electrical connection devices being equal in size.
connection device invention is made of a single body.
connection device invention can be made in miniature sizes.
connection device invention substantially maintains a constant elasticity through time.
an electrical connection device that in accordance with the main claim includes a main body which acts as a base for at least one tubular collar that creates a longitudinal axis and that includes a profiled section and a laminar body flexing elastically against said profiled section, the two being spaced apart and having parallel lengths, suited to form a longitudinal socket which can receive a male electrical connection device plugged in by a push-sliding movement and is characterised in that said laminar body is withheld at its end by anchoring devices so that at least its end is prevented from being raised beyond said profiled section.
the main body and the tubular collar are produced by a boxed construction from a single piece of blanked and bent sheet metal, where the profiled section is U-shaped.
the laminar body is set parallel to the profiled section and is encased within and spaced apart from the flat edges of the two facing sides that define the actual U-shaped profiled section.
laminar body is constructed as a boom anchored at both ends and, when pressing against the male contact device, develops a greater pressure than could be exerted by known types of electrical connection devices being equal in size and where the laminar body has a ledge-type construction.
the electrical connection device invention includes a main body 2 which acts as a base for a tubular collar, generally indicated by 3, that creates a longitudinal axis 4 and forms a socket 5 where the male contact device M is plugged in by a sliding and contrasting movement, as can be seen in figures 6 to 8.
the central body 2 and the tubular collar 3, constitute a monolithic part since they are made from a single piece of blanked and bent sheet metal that produces the boxed construction of the connection device illustrated in fig. 3.
the tubular collar 3 includes a U-shaped profiled section, generally indicated by 6, made of flat sides 6a, 6b, 6c where faces 6a and 6c are two opposite, parallel sides connected perpendicularly to the base 6b.
the profiled section may also have forms that differ from the U-shape described herein.
top edges 6d, 6e of sides 6a, 6c respectively, are parallel and spaced apart from a laminar body 7 set parallel to the profiled section 6 and encases within said U-shaped profiled section.
the appropriate thickness of the laminar body 7 and suitable material used in its construction make it flexible.
said laminar body 7 is withheld at its end 7a by anchoring devices suited to prevent at least the end 7a itself from being raised beyond said profiled section 6.
anchoring devices consist of two tabs 8, 9 belonging to the side faces 6a and 6c respectively of the profiled section 6, which are turned over the laminar body 7 and prevent it from being raised beyond the profiled section 6.
the profiled section 6 may have ribbing and/or grooving suited to firmly anchor the end 7a of laminar body 7 so that any kind of movement is prevented.
end 7a of laminar body 7 may even be welded to the profiled section 6.
the laminar body 7 As regards the laminar body 7, it can be seen in fig.'s 4 and 5 that halfway along its length it has a drawing 10 having a convex surface 11 bent towards the inside of the socket 5 which presses against the male contact device M when this is plugged into the actual socket 5.
the laminar body 7 presents itself basically as a boom that has one end locked by the main body 2 and its opposite end 7a anchored to the profiled section 6 by tabs 8 and 9, contrary to contact devices belonging to known technology described in the aforementioned patents, where the laminar body is instead constructed as a locked boom with its end free and therefore basically as a ledge.
the male contact device M When the male contact device M, as can be seen in figures 6 to 8, is plugged into the socket 5 of the tubular collar 3, it presses against the convex surface 11 of the drawing 10 and pushes the laminar body 7 upwards in the vertical direction indicated in fig. 7 by arrow 12. In fact the distance 13 between the convex surface 11 and the longitudinal ribbing 14, 15 made on base face 6b of the profiled section 6, is less than the thickness 16 of the male device M.
the level of force F depends on the deflection flexed by the laminar body F, which in turn depends on the difference between thickness 16 of the male device M and the distance 13 between the convex surface 11 and the longitudinal ribbing 14, 15 of the profiled section 6 which receives it.
laminar body 7 that can be considered as a boom anchored at both ends, against male device M creates a higher compression force F than that exerted by the, known type of connection illustrated in fig. 1 having the same length and where the laminar body F flexes to create the same deflection.
connection device invention can also be produced according to the different forms of execution that are described below.
FIG. 9 A variant in execution can be seen in fig. 9 where it is generally indicated by 20 and differs from the connection described earlier for the existence of a pair of tubular collars 3 of the kind described earlier, equal in size or even different, arranged at opposite ends of the main body 2.
the electrical connection device generally indicated by 30, includes a single tubular collar 3 and a male laminar body 31, arranged on opposite ends of the central body 2.
the electrical connection device generally indicated by 40, includes a tubular collar 3 and a clamp piece for electric cable, generally indicated by 41 and arranged on opposite ends of the central body 2.
connection device is generally indicated by 50 and where it can be seen that it includes a tubular collar 3 and a contact piece for printed circuits, generally indicated by 51, arranged on opposite ends of the central body 2.
contact piece for printed circuits 51 consists of a bar 52 having a prismatic section, bent towards the longitudinal axis 53 of the tubular collar 3 and with narrowing 54 at its end.
the anchoring devices at the end 61a of the laminar body 61 consist of a ring 62 that anchors the outside of end 61a of the laminar body 61 to the U-shaped profiled section 63.
the ring 62 can be attached or can belong to the profiled section 63.
connection device invention has been described with reference to the attached diagrams, it may also be constructed according to variants in execution that have not been described herein, which nevertheless fall under the inventive concept stated by the claims below and shall therefore be protected by this patent.
