[0001] The present invention refers to an electrical connector of small dimensions and through
which it is possible to perform, in a particularly easy manner, the connection and
disconnection of electrical cables with respect to the electrical connector itself.
[0003] In general, the known electrical connectors currently on the market have some drawbacks.
A first drawback is due to the fact that such electrical connectors are usually made
by assembling a plurality of distinct components, whether they are made from conductive
metallic material rather than insulating plastic material, with which the outer shell
or casing of the connector is normally made. Current electrical connectors are therefore
very bulky, in contrast with the tendency towards miniaturisation of the technical
field of lighting apparatuses with light emitting diodes.
[0004] Another drawback of known electrical connectors is due to the fact that they do not
always allow reliable use of the two main types of electric cables, in other words
solid cables and so-called stranded cables, or "multi-strand" cables, which have different
thicknesses to each other. A further drawback of known electrical connectors is due
to the fact that the connection and disconnection of the electric cables is guaranteed
exclusively by the use of additional tools, like for example screwdrivers, nails or
similar tools. These tools are indeed necessary to make it possible to open the metallic
contacts intended for the mechanical coupling of the electric cables. Yet another
drawback of known electrical connectors is finally due to the fact that it is impossible,
in many cases, to withdraw the electric cables for the subsequent reuse thereof without
compromising the reliability of the connector or of the respective components for
connecting and holding the electric cables themselves.
[0005] Documents
DE 10 2007 035336 B3 and
US 8328586 B2 in reality describe respective electrical connectors in which the capability of decoupling
the electric cables from the respective metallic contacts is provided. This functionality
is entrusted, in the case of document
DE 10 2007 035336 B3, to the use of an additional tool, schematised by a screwdriver, that requires further
and suitable functional components on the electrical connector that allow the use
of the additional tool itself. These functional components, acting not really in a
controlled form, deform critical metallic parts adapted for holding the electric cables.
In the case of document
US 8328586 B2, the decoupling functionality is entrusted to the correct operation of an element
made of plastic material integrated in the containment body, also made of plastic
material, of the electrical connector. However, due to its nature and the type of
application to which it is subjected, such an element is deformed not so much by the
insertion/removal action of the cables but rather, even before, in the step of reflow
soldering (with temperatures close to 300°C for many tens of seconds) that the electrical
connector undergoes in the implementation on the corresponding and appropriate electrical
circuits.
[0006] In addition, the element made of plastic material having a lever function described
in document
US 8328586 B2 has a mechanical problem due to its relatively small dimensions. Such an element,
indeed, is structurally not very suitable for undergoing continuous actuations that
facilitate the insertion/removal of the electric cables.
[0007] The purpose of the present invention is therefore to make an improved electrical
connector and assembly thereof that are capable of overcoming the aforementioned drawbacks
of the prior art in an extremely simple, cost-effective and particularly functional
manner.
[0008] In detail, a purpose of the present invention is to make an electrical connector
and assembly thereof that are able to improve the technical and functional aspects
of electrical connectors made according to the prior art. In particular, such technical
and functional aspects concern the possibility of reducing the number of components
necessary for the assembly of the connector, consequently reducing the size and bulk
of the connector itself.
[0009] Another purpose of the present invention is to make an electrical connector and assembly
thereof that do not require the use of additional tools to carry out the decoupling
of the electric cables from the respective metallic contacts. The use of such additional
tools, indeed, as well as forcing upon the electrical connector the addition of areas
and/or components suitable for the purpose, with a consequent increase in the bulk
dimensions and complexity of making the connector itself, can cause uncontrolled manoeuvres
such as to cause permanent deformations that reduce the coupling capability of the
electric cables.
[0010] A further purpose of the present invention is to make an electrical connector and
assembly thereof that are able to improve the logistical and productive aspects of
electrical connectors made according to the prior art. In particular, such logistical
and productive aspects concern the possibility of having modular electrical connectors
of predetermined shape, as well as modular electrical connectors that allow maximum
flexibility of supply and use.
[0011] Yet another purpose of the present invention is to make an electrical connector and
assembly thereof that are able to improve the economic aspects of electrical connectors
made according to the prior art, both in terms of the cost-effectiveness of solutions
at the design, constructive and productive level, and in terms of lower implementation
cost and greater flexibility of use.
[0012] These purposes according to the present invention are accomplished by making an assembly
comprising an improved electrical connector and a casing as outlined in claim 1.
[0013] Further characteristics of the invention are highlighted by the dependent claims,
which are an integral part of the present description.
[0014] The characteristics and advantages of an improved electrical connector and assembly
thereof according to the present invention will become clearer from the following

and

[0015] With reference in particular to figures 1 to 5, a first embodiment of an improved
electrical connector which is part of an assembly according to the present invention
is shown, wholly indicated with reference numeral 10. The electrical connector 10
consists of a containment cage 12 with structural function, made with an electrically
conductive material, preferably metal.
[0016] The substantially parallelepiped-shaped containment cage 12 is provided with a pair
of lateral walls 14, a lower wall 16 and an upper wall 18 that develop according to
a substantially longitudinal direction. The containment cage 12 is also provided with
a closure wall 20 at a rear end thereof. the containment cage 12 thus delimits a substantially
closed inner compartment for housing electric wires or cables (not shown) of various
type and size. The containment cage 12 is also provided, at the front end thereof,
with an opening 22 for the insertion of at least one electrical wire or cable to be
removably connected to the electrical connector 10.
[0017] An elastic pressure element 24 configured to hold the electric cable in contact with
the lower wall 16 of the containment cage 12 extends from the upper wall 18 towards
the inner compartment of said containment cage 12. In other words, the elastic pressure
element 24, preferably consisting of a flexible metal tab, operates as electrical
contact element and simultaneously holds - by friction - the electric cable, exploiting
the opposition force exerted by the lower wall 16 of the containment cage 12. One
or more elements 26 for connection with electrical circuits for the transmission of
the signals transferred by the electric cable extend from the lower wall 16 towards
the outer part of the containment cage 12.
[0018] On at least one of the lateral walls 14 of the containment cage 12, at the opening
22, a longitudinal slit 28 extends, adapted for the insertion and guided movement,
in the longitudinal direction, of a corresponding pin 30 (figure 7) that, acting as
an opening lever, opposes the action of the elastic pressure element 24 and allows
the electric cable to be inserted/extracted with respect to the electrical connector
10. The pin 30 is advantageously made of an insulating material, like for example
a plastic material.
[0019] The lateral walls 14, the lower wall 16, the upper wall 18, the closure wall 20,
the elastic pressure element 24 and the one or more elements 26 for connecting with
electrical circuits are made from a single block of electrically conductive material,
preferably metal, folded over on itself to form the containment cage 12. The structural
and box-shaped strength of the block that constitutes the containment cage 12 is guaranteed
by a fit-coupling obtained through one or more engagement couplings 32 obtained on
one of the longitudinal sides of such a containment cage 12, so that such one or more
engagement couplings 32 are capable of irreversibly connecting the lower wall 16 to
one of the lateral walls 14 of the containment cage 12.
[0020] More specifically, at least two engagement couplings 32 are provided on one of the
two longitudinal edges of the lower wall 16 of the containment cage 12, such engagement
couplings 32 being formed in an integral manner with the lower wall 16 itself. The
engagement couplings 32, of predetermined shape, are configured to fit-couple in corresponding
cavities 34 obtained on the lower edge of the corresponding lateral wall 14. The cavities
34 are countersunk-shaped and match with the shape of the corresponding engagement
couplings 32, so as to guarantee an irreversible fit-coupling between the lower wall
16 of the containment cage 12 and the corresponding lateral wall 14 of the containment
cage 12 itself.
[0021] Now with reference to figures 6 to 9, a second embodiment of the electrical connector
10 and assembly thereof according to the present invention is shown. In this second
embodiment the containment cage 12 is at least partially enclosed by a substantially
box-shaped casing 36, made with an insulating material and thus capable of electrically
and thermally insulating the electrical connector 10 with respect to the surrounding
environment.
[0022] The casing 36 is provided with a pair of lateral walls 40 and an upper wall 42 with
longitudinal development, capable of covering the corresponding lateral walls 14 and
upper wall 18 of the containment cage 12. The casing 36, on the other hand, is advantageously
open at its front and rear ends, both to allow the passage of the electric cables,
and to allow an axial sliding movement that will be described hereafter. The sliding
coupling between the casing 36 and the containment cage 12 is indeed obtained in a
simple manner and without the need to use special or dedicated tools.
[0023] In detail, the casing 36 is configured to move according to a substantially longitudinal
direction with respect to the containment cage 12 once such a containment cage 12
has been connected to the respective electric circuit, for example through welding
of the corresponding connection elements 26. The casing 36 is indeed provided, in
its lower part, with a pair of sliding guides 38 with longitudinal development, which
cooperate with the lower wall 16 of the containment cage 12 to allow a sliding movement
of the casing 36 itself with respect to such a containment cage 12.
[0024] The axial sliding movement of the casing 36 allows the easy insertion/removal of
the electric connection cables with respect to the electrical connector 10. In the
case in which the electrical connector 10 is provided with the casing 36, indeed,
such a casing 36 is internally provided with at least one abutment nib 56 that acts,
with the longitudinal movement action of the casing 36, as a lever for opening the
elastic pressure element 24, being inserted and moving in the longitudinal slit 28
of the containment cage 12.
[0025] For example, figure 7 shows an electrical connector 10 in an operative configuration
in which the opening lever 30 or 56 of the elastic pressure element 24 does not interact
with such an elastic pressure element 24. Such an opening lever 30 or 56, irrespective
of its specific embodiment, is indeed at a predetermined distance D from the elastic
pressure element 24. By making the casing 36 slide longitudinally with respect to
the containment cage 12 the distance D can be cancelled out or, in other words, the
opening lever 30 or 56 can be brought towards the elastic pressure element 24 until
mutual contact is obtained between these two components. A further longitudinal advancement
of the casing 36 ensures that the opening lever 30 or 56 opposes the action of the
elastic pressure element 24, opening the electrical contact and releasing the electric
cable without the need to intervene with external tools.
[0026] The casing 36 can in any case be provided, at the front end thereof intended for
the insertion of the electric cable, with a notch 46 adapted for the positioning of
a generic tool (screwdriver, punch, etc.). Such a tool allows the axial sliding movement
of the casing 36 to be performed should accessibility to the electrical connector
10 be limited.
[0027] The electrical connector 10 can be provided with at least one connection component
48 capable of mutually connecting two or more analogous casings 36, so as to allow
a modular assembly of two or more electrical connectors 10 to be obtained. Such a
modular assembly is sometimes necessary when there is a need to selectively connect
together multiple electric cables belonging to the same apparatus. The connection
component 48 can be removably applied to the casings 36 and can be adapted both to
monopolar electrical connectors 10, and to multipolar electrical connectors 10. Figure
11 represents, as an example, a multipolar electrical connector 10 with two connector
parts. In the multipolar version the positioning distance between the single casings
36 can be different both in a homogeneous manner (for example different but constant
distance for each position), and in a non-homogeneous manner (for example different
distances between each single position). This allows the single modules to be assembled
in such a way that their positioning on the tracks of the printed circuit can be satisfied
irrespective of their number and their distance apart.
[0028] Preferably, the connection component 48 is used up to the step of soldering on the
electric circuit, which typically takes place by reflow process. Such a connection
component 48 can then be removed from the electrical connector 10 by disengaging its
respective releasable hooking means 50 that work on the box-shaped body of each single
casing 36.
[0029] The removal of the connection component 48 in the multipolar solutions allows the
withdrawal of each single cable separately, as described earlier. Should the connection
component 48 not be removed, the withdrawal functionality of the cables would in any
case remain applicable, but allowing the removal of all of the cables in a single
operation.
[0030] The casing 36 can also be provided, at the front end thereof intended for the insertion
of the electric cable, with an abutment wall 44 that operates as safety element for
preventing uncoupling to keep the casing 36 always slidably connected to the containment
cage 12. The mechanical coupling of the containment cage 12 in the respective casing
36 can however be guaranteed both by the sliding guides 38 of the casing 36 itself,
and by a projecting tooth 52 (figure 1), obtained on such a containment cage 12, which
fits in a corresponding hollow seat 54 (figure 10) of the casing 36.
[0031] It has thus been seen that the improved electrical connector and the assembly thereof
according to the present invention achieves the purposes specified earlier.
[0032] The improved electrical connector and the assembly thereof according to the present
invention thus conceived can in any case undergo numerous modifications and variants,
all of which are covered by the same inventive concept; moreover, all of the details
can be replaced by technically equivalent elements. In practice, the materials used,
as well as the shapes and sizes, can be whatever according to the technical requirements.
[0033] The scope of protection of the invention is therefore defined by the attached claims.
