Description

The present invention relates to a support base for a wired electrical component.

The invention also relates to a lighting module comprising such a base and an electrical component such as a light-emitting diode.

The invention also relates to a method for producing a module comprising such a base and a garment comprising at least one such module.

Nowadays, there are many electrical components, in particular of small size, which need to be connected in a simple manner to an electrical circuit, in particular a supply or control circuit.

To do this, the component is generally mounted in a housing or on its support and electric wires are welded by hand or automatically for the electrical connection of the component.

However, this solution is tedious and expensive, and the smaller the component, the more difficult it becomes to make these welds.

In the field of connectors, solderless connections are known, for example, in particular by crimping (see for example FR2956780 ). This generally involves connecting a sheet of electrical wires to a connector. To do this, electrical contacts or plugs are made, one male end for example of which is held in a connector housing and the other end of which has crimping pins which pass through the cable to ensure the electrical connection. The crimping pins are also enclosed on the cables for a mechanical hold between the electric wire and the electric plug.

The crimping operation must generally be carried out using a specific crimping pliers, which limits its field of use. Thus, there is no specific tool for connecting, for example, a single electric wire by crimping.

The document US20011 / 0215368A1 describes a socket for a wired electrical component according to the preamble of independent claim 1.

The object of the invention is to at least partially remedy the aforementioned defects.

• au moins une rainure apte à recevoir un fil électrique destiné à être connecté au composant électrique,

caractérisée en ce que ladite au moins une rainure présente en section transversale :

• une portion conformée pour recevoir un fil électrique et
• un fond convergeant servant de forme de sertissage lors de l'insertion du contact électrique de sertissage dans la rainure.

To this end, the subject of the invention is a base for a wired electrical component comprising:

characterized in that said at least one groove has in cross section:

• a portion shaped to receive an electric wire and
• a converging bottom serving as a crimp shape when inserting the electrical crimping contact into the groove.

In fact, it suffices to assemble to the base the electrical component equipped with one or more electrical crimping contacts, so that the crimping elements such as pins of the or each electrical crimping contact come to deform when they meet the bottom converging with an associated groove of the base.

According to one aspect of the invention, said at least one groove has an access channel for the electrical crimping contact, the access channel being arranged opposite the converging bottom.

• the access channel of the electrical crimping contact with orientation substantially perpendicular to the axis of the groove and having a width smaller than the maximum width of the portion shaped to receive an electrical wire, and

The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the characteristics apply only to one embodiment. Simple features of different embodiments can also be combined to provide other embodiments.

First embodiment

The figures 1 and 2 show schematic perspective views respectively from above and from below of a base 1 for a wired electrical component.

This base 1 has for example the shape of a disc or of a pellet, but other shapes can be envisaged, for example square or oval without departing from the scope of the present invention.

The shape of the base 1 is shaped to allow mounting of the base 1, for example on another support, for example a wall, a fabric or a canvas, a rigid or flexible case, etc. For this purpose, provision can also be made to provide the base 1 with lateral fixing lugs (not shown) for screwing or gluing the base 1.

The base 1 is for example made of plastic, for example by injection molding.

The base 1 comprises a housing 3 for receiving an electrical component 5 equipped with at least one electrical crimping contact 7 (see figure 4 ).

In the present exemplary embodiment, the electrical component 5 is for example a light-emitting diode 9.

In other embodiments, the electrical component can be for example a sensor (temperature sensor, sensor of a magnetic and / or electric field, light sensor / photodiode), a power supply battery, a transmitter / receiver for example an antenna etc. Generally speaking, this is an electrical component a few mm wide which must be connected to individual electrical wires.

The housing 3 is in this case a through opening 11, for example of square shape and having on the front face 13 of the base 1 a flared shape 15 upwards (that is to say in a direction substantially parallel direction of emission of the diode) favoring the emission of a cone of light by the light-emitting diode 9 when the latter is mounted in the base 1.

On a more advanced version, provision can be made for the flared shape 15 to be metallized, for example, to act as a reflector.

Front face 13 is understood to mean the face of the base 1 from which a light emitting diode 9 can emit light when such a diode 9 is mounted in the base 1. The rear / front direction of the base 1 is therefore substantially parallel to the direction of emission of such a light-emitting diode 9.

The front face 13 also corresponds to the face of the base 1 intended to be at least partially visible when the base 1 is mounted on a support such as a fabric or clothing. In particular, this front face 13 is intended to be fixed, for example by gluing, on the support, such as a fabric or garment, so that the part of the front face 13 of the base 1 having the housing 3 and the flared shape 15 is projecting relative to this support, passing in particular through a corresponding hole of complementary shape provided on the support intended to receive the base 1.

As an alternative or in addition, this front face 13 can be fixed to an assembly washer 60 (visible on the figure 22 ) for example by ultrasonic welding so as to take the support such as a fabric or garment sandwiched between this assembly washer 60 and the base 1. The part of the front face 13 of the base 1 having the housing 3 and the flared shape 15 is in this case also suitable for passing through the corresponding hole of complementary shape of the assembly washer 60.

As best seen on the figure 2 , the base 1 comprises at least one, in this case two grooves 17. The groove or grooves 17 are advantageously formed on the rear face 18 of the base 1. The term “rear face 18” is understood to mean the face of the base 1 opposite the front face 13. This rear face 18 is intended to no longer be visible from the outside when the base 1 is mounted on a garment for example.

In general, the base 1 has as many grooves 17 as there are electrical wires to be connected to the electrical component 5.

Each groove 17 has in cross section a particular shape shown according to one embodiment on figure 3 .

Thus, the groove 17 has in cross section on the one hand a portion 19, for example of generally substantially cylindrical shape, shaped to receive an electric wire 21 (see figure 5 ) and on the other hand an access channel or access passage 23 of the electrical crimping contact 7. As seen in the figures 1 to 3 , the access channel 23 is in this example of orientation perpendicular to the axis 24 of the groove 17, here the longitudinal axis 24 of the groove 17. The access channel 23 has according to the example illustrated, a width L _A smaller than the maximum width L _MAX of the portion 19 here of generally substantially cylindrical shape. This maximum width L _MAX corresponds in the example illustrated to the diameter of the portion 19.

Thus, when inserting a suitable electric wire 21 having for example a diameter slightly less than the width L _MAX but greater than the width L _A of the access channel 23, it is guided longitudinally in the groove 17 without being able to come out. .

The width L _A of the access channel 23 is dimensioned so as to be slightly greater than the width L _C (see figure 4 ) of the electrical crimping contact 7.

On the example of the figure 3 , the groove 17 has a converging bottom 25 opposite to the access channel 23. This converging bottom 25 consists of two inclined straight slopes 27 which terminate on a straight bottom 29 parallel to the rear face 18 of the base 1.

This converging bottom 25 with its inclined slopes 27 serves as a form of crimping during the insertion of the electrical crimping contact 7 in the groove 17.

Furthermore, the base 1 comprises a peripheral edge 31 partially covering the groove 17. This peripheral edge 31 serves on the one hand to retain the electrical wires 21, in particular against a tearing in the direction perpendicular to the rear face 18 of the base 1 and on the other hand the retaining edge in order to be able to cast a sealing layer after assembly of the electrical component 5 (this will be explained later).

The figure 4 shows a schematic perspective view of the electrical component 5 equipped with at least one, in this case with two electrical crimping contacts 7.

As explained above, the electrical component 5 is for example a light emitting diode 9.

The electrical crimping contacts 7 each include a pad 33 (visible on the figure 7 ) flat, for example soldered to the supply terminals of the diode 9 and a part with crimping pins 35.

In the present example, the two electrical contacts 7 are parallel to each other.

We will now describe an exemplary embodiment for mounting a module such as a lighting module 37 (see figure 9 ) with reference to figures 5 to 9 .

This lighting module 37 comprises a light emitting diode 9 of the figure 4 and a base 1 as shown in the figures 1 to 3 .

The figure 5 is a schematic exploded perspective view of a lighting module according to the invention before assembly with the base 1, the light-emitting diode 9 equipped with two electrical crimping contacts 7 and two wires electric 21.

According to a first step, an electric wire 21 is threaded in each groove 17 according to the arrow F1.

Then, along the arrow F2, is inserted through the rear face 18 of the base 1 the diode 9 equipped with its two crimping contacts 7 with the crimping pins 35 directed in the direction of the associated grooves 17 so that during the insertion crimping on the electric wires 21 is carried out.

The base 1 therefore fulfills both the function of support or protective casing for the electrical component 5 and the function of a crimping counter-form to make the electrical connection with the electrical wires 21.

During this insertion, the pins 35 will pierce the electrical wires 21 so as to establish electrical contact with the strands of the core 39 (see figure 8 ) of the electric wires 21, then the pins 35 will deform inwardly by meeting one of the inclined straight slopes 27. This deformation will also allow good mechanical retention between the electric wire 21 on the one hand and the electrical crimping contacts 7 on the other hand.

On the figure 7 The light-emitting diode 9 is shown crimped on the two electric wires 21.

According to an optional step, a transparent resin 40 is then poured onto the front face 13 of the base 1, so as to cover the diode 9 and obtain a convex shape acting as a lens for the diode 9.

On the rear face 18 of the base 1, for example, a sealing layer is also poured (not visible in the figures).

In this way, a waterproof lighting module 37 is obtained which is protected against humidity and dust.

The figure 9 shows the lighting module 37 in the form of a pellet, the electric wires 21 of which can now easily be connected, for example, to a power supply unit (not shown).

Such a module 37, for example a lighting module, can then be fixed on a support such as fabric or clothing. As said previously, the module 37 can be fixed by the front face 13 of the base 1 against the support, so that at least part of the front face 13 having the housing 3 passes through a corresponding and complementary hole provided on the support.

The base 1 can be fixed to the support by gluing the front face 13 to the support.

As an alternative or in addition, in order to fix the base 1 on a support, an assembly washer 60 can be provided (cf. figures 22 and 23 ) arranged against the support and the base 1 is arranged so that the support is sandwiched between the base 1, more precisely the front face 13 of the base 1, and this assembly washer 60. In this In this case, the part of the front face 13 having the housing 3 also passes through a corresponding hole of a complementary shape to the assembly washer 60. The base 1 and the assembly washer 60 can be fixed by ultrasonic welding.

Of course, the order of certain steps previously described can be inverted.

Second embodiment

The figures 10 to 11 show another embodiment of the base and the light-emitting diode 9 which differs from that of figures 1 to 9 and which is particularly advantageous for a series connection of several lighting modules 37, by the fact that it comprises two pairs of grooves 17 on either side of the housing 3 and that the electrical crimping contacts 7 have pins crimping 35 on either side of the light-emitting diode 9. This second embodiment is well suited for placing several lighting modules in parallel.

The assembly and mounting of this second embodiment is carried out in a manner similar to what has been described in relation to the first embodiment.

The figure 13 shows a variant of the light emitting diode 9 with its electrical crimp contacts. Compared to the figure 11 , the electrical contacts 7 are initially raised with folding lines 41, so that during assembly, it suffices to place the diode 9 in its housing, then to lower the pins 35 to crimp the electrical contacts 7 on the cables 21.

Third embodiment

The figure 14 shows yet another variant of the base 1 which differs from the first or second embodiment in that the base 1 has a mounting groove 43 around its periphery. This variant is for example well suited to mounting a module with a base 1 and an associated electrical component 5, on a fabric in the manner of a button, for example for a signaling garment, such as a vest or a parka or a signaling scarf or belt.

Fourth embodiment

We describe with reference to figures 15 to 19 , a fourth embodiment of the base 101. Only the differences from the first embodiment described with reference to figures 1 to 9 , are detailed below.

Similarly to the first embodiment, the base 101 comprises at least one groove 117, here two grooves 117, respectively having in cross section a portion 119 capable of receiving an electric wire 21 and a converging bottom 125.

Each groove 117 is here delimited by two opposite walls 116 of the base 101. The shape of a groove 117 differs from the first embodiment, in particular in that the portion 119 adapted to receive the electric wire 21 no longer has a shape. general cylindrical diameter L _MAX . According to the example illustrated, substantially flat opposite walls 116 delimit the portion 119. In this example, the portion 119 has a constant width.

As for the converging background 125, it is better visible on the figure 18 , serves as a crimp form when inserting the electrical crimp contact 7 into the groove 117.

Similar to the first embodiment, the converging bottom 125 comprises two inclined straight slopes 127 which terminate on a straight bottom 129 substantially parallel to the rear face 118 of the base 101. The inclined straight slopes 127 are inclined with respect to the base. right bottom 129 of the groove 117 and are inclined so as to approach each other at the level of the right bottom 129.

Of course, other convergent shapes of the converging bottom 125 can be envisaged.

Referring again to the figure 16 , according to this fourth embodiment, the or each groove 117 is defined in a non-rectilinear shape, for example substantially bent. In this case, the or each groove 117 of the base 101 does not extend along a single rectilinear longitudinal axis 24 as described with reference to the first embodiment of the figures 1 to 9 .

• une première portion 117₁ à proximité du logement 103 destiné à recevoir le composant électrique 5 s'étendant selon une première direction, et
• une deuxième portion 117₂ éloignée par rapport au logement 103 s'étendant selon une deuxième direction différente de la première direction, par exemple sensiblement perpendiculaire à la première direction.

In this example, the or each groove 117 extends along a substantially bent axis and has a generally substantially "L" shape. Thus, the or each groove 117 comprises:

• a first portion 117 ₁ near the housing 103 intended to receive the electrical component 5 extending in a first direction, and
• a second portion 117 ₂ remote from the housing 103 extending in a second direction different from the first direction, for example substantially perpendicular to the first direction.

The intersection or the bent portion between the first portion 117 ₁ and the second portion 117 ₂ of the groove 117 is advantageously curved.

According to the example illustrated in which a base 101 comprises two grooves 117, the first portions 117 ₁ of the two grooves 117 extend substantially parallel while the second portions 117 ₂ extend in the same direction in the opposite direction.

The or each groove 117 then has a proximal end 120 ₁ by relative to the housing 103 and a distal end 120 ₂ remote from the housing 103, which is not aligned with the proximal end 120 ₁ . The proximal end 120 ₁ is provided at the level of the first portion 117 ₁ while the distal end 120 ₂ is provided at the level of the second portion 117 ₂ . More precisely in this example, the proximal end 120 ₁ and the distal end 120 ₂ are oriented in two directions which are substantially perpendicular to one another. The distal end 120 ₂ allows the insertion of an electric wire 21 adapted in the associated groove 117.

The insertion of an electric wire 21 in a groove 117 along such a bent axis of the groove 117, as shown schematically by the arrow F3 on the figure 18 , makes it possible to manage the bending of the electric wire 21 and to avoid a risk of damage to the electric wire 21 in the face of external stresses, once a module comprising a base 101 and an associated electric component 5, mounted and / or in operation .

Finally, according to this fourth embodiment, the or each groove 117 may include an access channel 123 or access passage for the electrical crimping contact 7. This access channel 123 allows insertion of the electrical crimping contact 7 according to an axis F2 substantially perpendicular to the axis of the groove 117, more precisely to the axis of the first portion 117 ₁ of the groove near the housing 103. More generally, the axis F2 of insertion of the electrical crimping contact 7 is substantially perpendicular to the general plane defined by the base 101.

Moreover, according to the example illustrated, the access channel 123 does not have a width smaller than the maximum width of the portion 119 capable of receiving the electric wire 21.

One could consider, according to a variant not shown, a narrowing opposite the converging bottom 125 of the groove 117, so as to form an access channel of smaller width than the portion 119, allowing, when inserting a suitable electric wire 21 , for example having a diameter slightly less than the width of the portion 119 but greater than the width of the constriction forming the access channel, that it is guided in the groove 117 without being able to leave it.

Furthermore, according to the fourth embodiment illustrated in the figures 15 to 19 , the base 101 may no longer have a peripheral edge 31 as described in the first embodiment with reference to figure 2 . In this case, an edge 131 '(see figures 16 and 19 ) is provided around the groove or grooves 117 and the housing 103 to receive the electrical component 5 and no longer on the periphery of the base 101. The edge 131 'extends in relief with respect to the general plane defined by the base 101, more precisely with respect to the plane defined by the rear face 118 of the base 101. The edge 131 ′ therefore extends at a predefined height substantially perpendicular to the plane defined by the rear face 118 of the base 101.

The thickness of such an edge 131 ′ is defined by the person skilled in the art as required. As is best seen on figures 16 , 17 and 19 , the edge 131 'can also form a dividing wall 132 between two grooves 117 of the base 101. According to the example illustrated, the dividing wall 132 extends between the first portions 117 ₁ of the grooves 117. It goes from the wall 132 extends in a direction substantially parallel to the grooves 117, here to the first portions 117 ₁ of the grooves 117. The separation wall 132 is therefore made in one piece with the edge 131 '. The wall 132 extends in relief relative to the general plane defined by the base 101, more precisely relative to the plane defined by the rear face 118 of the base 101

Furthermore, according to the fourth embodiment, the base 101 may have one or more locking portions 145. This makes it possible to prevent the tearing of the electric wire 21 in a groove 117 in the mounted state. In fact, the blocking portion (s) is / are able to compress the electric wire 21 in the associated groove 117.

According to the example shown on figure 16 , the base 101 has a locking portion 145 at the level of each groove 117. Of course, two locking portions 145 can be envisaged at the level of a same groove 117, for example facing each other.

The or each locking portion 145 is for example integral with the base 101. More precisely, the or each locking portion 145 is integral with the base 101, in this example with the edge 131 ′. With particular reference to the enlarged part of the figure 16 , a locking portion 145 is here formed by a folded section of a wall 116 at the distal end 120 ₂ of the groove 117. The locking portion 145 therefore extends from said wall 116 towards the interior of the groove 117. In addition, the locking portion 145 advantageously extends over a predefined distance making it possible to come into abutment against the electric wire 21 when the latter is inserted into the associated groove 117, so as to compress the electric wire 21 between this blocking portion 145 and the screw wall 116 -to-be. The facing wall 116 may, according to a variant not shown, have another similar locking portion 145, thus the electric wire 21 when inserted would be compressed between two locking portions 145.

Moreover, such a blocking portion 145 also provides a sealing function by making it possible to limit the possible penetration of liquid such as water.

Of course, provision can be made for the base 101 to have two pairs of grooves 117 similarly to the second embodiment described above.

The base 101 can also receive an electrical component 5 as illustrated on the figures 4, 5 , or according to the variant illustrated on figure 11 or on the figure 13 .

Finally, the base 101 may optionally have a mounting groove in a manner similar to the third embodiment.

The method of making a module 137, such as a lighting module comprising such a base 101 and an electrical component 5 comprising for example a light-emitting diode 9, is similar to that of the first embodiment, except that according to a first step, by way of nonlimiting example, an electric wire 21 is threaded into each groove 117 according to arrow F3. Of course, alternatively, the electric wire 21 can, beforehand, be shaped in a complementary manner to the bent shape of the groove 117 and be inserted into the groove 117 according to the arrow F2 (namely upwards with reference to the layout of the figure 18 ). Then insert the electric component 5, here the diode 9, for example by the face rear 118 of the base 101, according to arrow F2. More precisely, the electrical component 5, in this example the diode 9, equipped with its two crimping contacts 7 is inserted with the crimping pins 35 directed in the direction of the second part of the associated grooves 117 so that during the insertion , a crimping on the electric wires 21 is carried out.

Likewise, with reference to figures 22 and 23 , the mounting of such a module to a support such as a fabric or garment using an assembly washer 60 can be done in a similar manner to the first embodiment.

Fifth embodiment

We have represented on the figures 20 and 21 a fifth embodiment of the base 201. Only the differences with respect to the fourth embodiment described with reference to figures 15 to 19 , are detailed below. Identical items are not described again.

As previously, the base 201 comprises one or more grooves 217, here two grooves 217. The base 201 further comprises at least one flow guide 247, 249 at at least one groove 217, to facilitate distribution. a sealing layer or resin (not visible in the figures) cast for example on the rear face 218 of the base 201 after assembly of the electric component 5 and the electric wires 21, even below an electric wire 21 with reference to the arrangement illustrated on figure 21 . In order to facilitate the reading of the figure 21 only an electric wire 21 is shown.

According to the example illustrated, a flow guide can be produced in the form of a discontinuity 247 between the edge 231 'and the wall 232 between two grooves 217. The dimensions of such a discontinuity 247 are defined by Man. trade as needed. By way of non-limiting example, this discontinuity 247 is here formed near the intersection, here bent, between the first portion of groove 217 ₁ and the second portion of groove 217 ₂ . In other words, in this example, the discontinuity 247 is provided near the change in orientation of the grooves 217.

Of course, any other location of the discontinuity 247 can be considered to facilitate the flow of the sealing layer or resin even below an electric wire 21 in the mounted state of the module 237 comprising the base 201, the component electric 5 and the electric wire (s) 21.

The discontinuity 247 is advantageously provided at a place where, in the mounted state, the electric wire 21 is more stable, for example at a place where the crimping is more effective.

As a variant or in addition, a flow guide can be produced in the form of at least one notch 249 provided on the edge 231 'at the level of at least one groove 217. By making such a notch 249, the width of the groove 117 is increased at this point.

The notch or notches 249 may be formed near the first portion of groove 217 ₁ and / or the second portion of groove 217 ₂ . In the case of several grooves 217, at least one notch 249 can be provided at the level of each groove 217. In particular, the notch or notches 249 can be made on the edge 231 ′ at the level of the two grooves 217 in a symmetrical manner, such as as illustrated on figures 20 and 21 .

Of course, any suitable location of the notch or notches 249 can be considered to facilitate the flow of the sealing layer or resin, even below an electric wire 21 in the mounted state of the module 237 comprising the base 201. , the electrical component 5 and the electrical wire (s) 21.

In addition, in order to ensure that the sealing layer or resin passes well below the electric wire 21 in the mounted state, a difference in height or difference in level of the bottom of the or each groove 217 can be provided. By "height" means the dimension in the direction in which the edge 231 'extends in relief with respect to the rear face 218 of the base 201, namely substantially perpendicular to the plane defined by the rear face 218 of the base 201. According to the example illustrated on figure 20 , there is provided for this purpose at least one step 251 which makes it possible to establish a difference in level with the bottom of the rest of the associated groove 217. The step 251 is therefore higher than the bottom of the rest of the associated groove 217. In other words, the electric wire 21 in the mounted state resting on this step 251, is raised relative to the bottom of the rest of the groove 217.

Thus, this difference in level or height in the bottom of the associated groove 217 makes it possible to guarantee that the sealing layer or resin forms a ring around the electric wire 21, and therefore passes well below the electric wire 21 with reference to the arrangement shown on figure 21 .

Similarly, a base 1 according to the first, second or third embodiment with reference to figures 1 to 14 may have a flow guide, for example in the form of discontinuity or notch (s) making it possible to facilitate the flow and better distribution of the sealing layer or resin.

Of course, the characteristics of the various embodiments described above can be combined without departing from the scope of the invention.

In addition, the figures 1 to 23 illustrate a base 1; 101; 201 made in one piece. Of course, one can consider a base made in more than one part, for example in two parts. These two parts are joined together so as to form a base as described above.

It is therefore understood that the base 1, 101, according to one or the other of the embodiments described above, makes it possible to connect an electrical component 5 easily and easily without specific tools to individual electrical wires 21.
