Definitions
- the invention relates to a method of manufacture of contact strips for connectors of electrical equipment, said strips of contacts being obtained by segmentation of a strip secondary contact made from tape metallic.
- Recesses are made with one step regular initial in the metallic ribbon to form a discontinuous central strip of lamellae whose longitudinal ends are attached to two bands lateral continuous strips, each of said strips undergoing a twisting operation around its axis longitudinal to pivot relative to the plane of said ribbon, each strip additionally undergoing an operation bending so that each of its two faces has at least one protruding area to form a contact on one side of said plane.
- Said operations of twisting and bending allow for a strip primary contact whose lamellae are substantially spaced at the same regular pitch as the pitch initial of said recesses.
- the process includes besides a pleating operation of said strip primary contact consisting of forming folds on each side continuous strip so as to bring together slats from each other, and also has a hardening heat treatment operation intended to give the lamellas hardness properties combined with a certain elasticity so that they behave like springs.
- Such a process is known from the patent document FR2811147, for which the ribbon used in the process is not necessarily metallic. In practice, a beryllium-based alloy is often preferred.
- the central part of one side of the ribbon is covered a layer of a metal which is a good conductor electric, for example money.
- One of the edges of each strip is folded up in the hem in the direction where the conductive layer remains outside, so that current can flow through this layer conductive between the two lamella contacts.
- the layer must therefore have sufficient thickness to present a suitable conduction section.
- the covering the central part of one side of the ribbon by the conductive layer is usually done by mechanical plating, and this central part has therefore a lower elasticity compared to side parts of the tape after treatment thermal curing of the contact strip.
- the pleating operation allows the process of arriving at contact strips which have a large number of lamellae per unit of strip length. Because the side parts of the tape is not covered, pleating can be made in one or more folds, for example in one single narrow fold which is folded down substantially parallel to the plane of the ribbon, as shown in the patent FR2811147 mentioned previously. So there is no particular difficulty in obtaining by this process a high lamellar density along the length of a contact strip.
- a shadow cone is defined as a portion a lamella located behind another lamella in the direction of the electric field used for the galvanizing.
- the more the slats get overlap in the direction perpendicular to the ribbon the greater the risk of having air bubbles in particular trapped during galvanizing is important.
- the invention aims to remedy the drawbacks of these known solutions, by proposing a solution particularly less expensive in terms of manufacturing and storage while allowing quick order fulfillment.
- the secondary contact strip can be obtained from a long ribbon, and be delivered by example in the form of a coil which will be cut into contact strips by the customer just before these strips be assembled on their connectors destination.
- the metallization of said ribbon is carried out by galvanization.
- Galvanization can for example be carried out by electrolysis with money.
- the strip to be galvanized can be made of a beryllium-bronze alloy, which has poor electrical conductivity but good resilience properties after treatment thermal. Heat treatment of beryllium-bronze may consist of heating to around 320 ° C for four hours, followed by cooling progressive.
- the entire surface of said tape is covered during the metallization operation.
- galvanized metallization electrolytic it is in the current state of the art cheaper to fully galvanize rather than treating only the central strip of the ribbon.
- the metallization operation tape is made before said opening.
- said slats are brought together to be regularly spaced according to a new regular step such as the relationship between the initial step and this new pitch is between 1.3 and 2.
- a new regular step such as the relationship between the initial step and this new pitch is between 1.3 and 2.
- the invention also relates to a strip of contacts for connector of a switchgear electric, obtained from a metallic ribbon in which of the recesses are made to form a discontinuous central strip of lamellae, said strip of contacts being metallized over its entire surface by a layer of a metal that is a good electrical conductor, longitudinal ends of said strips being attached to two continuous lateral bands of said ribbon which are pleated in transverse folds, said strips being regularly spaced according to a not regular, characterized in that each fold has a height such that the ratio between said not regular and said height is between 1.7 and 2.5.
- the dimensional characteristics that have each fold of such a contact strip are particularly advantageous in order to allow a pleating relatively simple to perform and which does not no risk of breaking the conductive metal layer at the level of said continuous lateral bands of the ribbon.
- Such a contact strip according to the invention is particularly interesting in terms of performance / cost ratio if obtained by a manufacturing process according to the invention.
- Figures 1 to 3 illustrate the steps of a example of implementation of the method according to the invention for the production of high contact strips slat density.
- FIG. 3a schematically represents a another example of making a transverse fold in a ribbon of strips.
- Figure 4 schematically shows a suitable lamella shape so that each of the two faces of the coverslip may have two areas of contact.
- Figure 5 shows schematically a view in cross section of an installed contact strip in a part of a connector, formed from a slat ribbon such as that shown on the figure 4.
- Figure 6 schematically shows a view in cross section of a similar contact strip to that shown in Figure 5 and installed in part of a connector which includes means for longitudinal locking of the strip.
- FIG. 6a schematically represents a view in longitudinal section of the device of FIG. 6.
- a metallic ribbon 9, visible in FIG. 1, is covered on both sides with a layer 15 of a metal good electrical conductor as visible on the Figure 1a.
- a metal good electrical conductor as visible on the Figure 1a.
- At least the central strip CS of the ribbon is covered by the layer 15, and regularly spaced recesses 2 are perforated in this central strip as visible in Figure 2. These recesses can possibly be practiced before the ribbon either covered by layer 15 of good metal driver, as explained below.
- the metal of ribbon is for example an alloy of beryllium and bronze, which is a relatively poor conductor electrical, and metallization consists for example of electrolytic galvanizing in a bath silver.
- metallization consists for example of electrolytic galvanizing in a bath silver.
- the edges of the ribbon are covered with a layer joining its two faces, like the 15s layer shown in Figure 1a.
- the recesses 2 are made in the metallized ribbon of Figure 1a with an initial pitch d 1 regular in the direction of the longitudinal axis A of symmetry of the ribbon, to form a discontinuous central strip CS of lamellas 3 whose ends longitudinal 31 and 32 are attached to two continuous lateral bands ES 1 and ES 2 of the ribbon. It is preferable that the recesses are fairly narrow at their sizes which are located here along the longitudinal axis A of symmetry of the ribbon, in particular in order to obtain an initial pitch d 1 as small as possible for a given width of lamella , and also to limit the amount of material hollowed out.
- the width D of each strip is greater than approximately 80% of the initial pitch d 1 , which amounts to saying that the width of a recess at its size is at most equal to approximately 20% of d 1 since this width at size is equal to d 1 -D.
- the initial pitch d 1 of the recesses it is indeed undesirable for the initial pitch d 1 of the recesses to be much greater than D, as this would require using a longer metallized strip and increasing the width of the recesses, this which would be penalizing for the manufacturing cost.
- the height of the folds increases with the initial pitch d 1 , while it is undesirable to have folds too large which could hinder the mounting of the contact strip on the destination connector.
- the two lateral strips ES 1 and ES 2 of the ribbon are notched towards the outside of the ribbon so as to form tabs 4 which will be used for the connection of the contact strip with one of the parts of the connector for which it is intended.
- the lamellae 3 are here symmetrical with respect to their longitudinal axes A T which are perpendicular to the longitudinal axis A, but one could envisage a design which is not perfectly symmetrical by adopting a somewhat asymmetrical recess shape.
- the slats undergo then a twisting operation around their axis longitudinal to rotate relative to the ribbon plane so that the two faces of each lamella form two prominent contacts 3A and 3B respectively of each side of this plane, as visible in the first part of the figure 3.
- This twisting operation is accompanied by conventionally of a bending of the two lateral edges of each strip along at least one longitudinal plane perpendicular to the plane of the ribbon, in order to form on each side of a strip at least one contact area intended to ensure the passage of current between the strip and part of a connector.
- a contact such as 3A or 3B is consisting of at least one contact area.
- the overall resistance of the strip contacts should be decreased without increasing the area tape or decrease its thickness, it may be metallization is necessary on a tape already hollowed out, i.e. after the slats have been cut and possibly twisted and bent. In effect, the good conductive metal then covers the two surfaces as well as the edges of each lamella.
- the current that flows between the two contacts 3A and 3B of a strip is therefore distributed between the thickness of the tape 9 and the edges of the strip, this which allows to decrease to a certain extent the overall resistance of the contact strip obtained.
- metallization performed at this stage most often involves a substantial additional cost per report to an order of operations in which the metallization is carried out at the very start of the process, for the reasons mentioned above.
- FIG. 3 shows a view in longitudinal section of the secondary and primary contact strips, along a plane perpendicular to the plane P of the ribbon and passing through its longitudinal axis A.
- the primary contact strip obtained after the operation of torsion of the lamellae of the contact strip which is represented in FIG. 2, is visible on the right side of FIG. 3.
- the lamellas 3 are spaced at the same initial pitch d 1 as the pitch of the recesses 2.
- the tongues 4 are already inclined with respect to the plane P of the ribbon, as visible in FIG. 5.
- the left side of the figure shows the secondary band before its heat treatment, obtained following the pleating of the two continuous lateral bands ES 1 and ES 2 of the ribbon so as to bring the slats 3 together in a new step d 2 .
- the pleating operation mentioned above must take place after the metallization operation of the ribbon, in order to avoid poor metallization at the parts of the lamellae which overlap each other.
- the initial step d 1 is for example equal to 2.5 mm
- the corresponding new step d 2 is equal to 1.7 mm, which amounts to an approximation factor d 1 / d 2 lamellae close to 1.5. It can be seen that the lamellae partially overlap each other in the direction perpendicular to the plane P of the ribbon. However, the distance between the edge of a strip and the surface of the nearest adjacent strip must remain sufficient so that this edge does not abut against said surface when the contact strip obtained is installed and compressed between two parts of a connector such as the two parts 11 and 12 shown in FIG. 5. Thus, from a given primary strip of contacts, there is a lower limit not to be crossed for the new step d 2 .
- This limit depends in particular on the inclination of the strips relative to the plane of the strip, on the elasticity desired for the strips, as well as on the width D and the thickness of the strips. There is therefore a compromise to be adopted in order to have a pitch d 2 as small as possible, with a view to obtaining a high density of lamellae which goes hand in hand with a good conduction capacity for high currents.
- the initial pitch d 1 must itself be sufficient to be able to cut fairly large strips in order to be able to bend them and form zones whose contact surfaces are satisfactory with the two parts of the destination connector. In addition, it is important to have strips whose width D is sufficient to ensure the desired elastic clearance at the contacts of each strip, since each strip of the contact strip obtained is capable of pivoting in an elastic manner. However, a large lamella width will oblige to a certain extent to increase the new pitch d 2 , which goes against a high density of lamellae. As it is not desirable that the initial pitch d 1 be greater than 1.25 times the width D desired for the slats, as explained in the commentary to FIG. 2, there is therefore a compromise to be adopted in order to limit as much as possible this initial step.
- the mutual overlap of the lamellae of the secondary strip is clearly visible on the left of the figure.
- the tongues 4 are regularly spaced with the same new pitch d 2 as for the strips.
- the folds 5 which have been made transversely to the ribbon in order to bring the strips 3 together are all prominent on the same side of the plane P of the ribbon, preferably on the same side as that towards which the tabs 4 are folded.
- the two continuous lateral bands ES 1 and ES 2 of the ribbon take on a crenellated shape with slots separated two by two by the bottom of a fold 5.
- the internal walls of a fold 5 do not touch each other, so that the curvatures applied to the continuous lateral bands of the ribbon during pleating do not risk breaking these bands.
- This characteristic is especially advantageous in the case where the lateral strips ES 1 and ES 2 are covered with a conductive layer 15 as well as the central strip CS of the ribbon, since it is mainly at this layer 15 that it can there is a risk of tearing if the folds are formed by pressing one wall against another.
- Each fold thus has an interior space forming a cavity 6 open at the plane P of the ribbon.
- Each cavity has two walls substantially planes which are parallel to each other and perpendicular to the plane of the ribbon for the example of embodiment of Figure 3, and also includes a wall semi-cylindrical which forms the bottom of the cavity 6.
- the bottom of this cavity thus has a diameter of curvature ⁇ which corresponds to the diameter of the half cylinder, this diameter ⁇ also being here equal to the distance which separates the two flat walls of the cavity.
- each transverse fold 5 has a height h such that the ratio d 2 / h between the new regular pitch d 2 and this height is between 1.7 and 2.5.
- the height of a fold is measured as the distance between the flat surface of the side band on the side of the fold and a plane parallel to this surface which is tangent to the top of the fold, which supposes that each fold is prominent by the same side of the ribbon plane. For example, we can have a fold height equal to 0.85 mm for a new pitch equal to 1.75 mm, which gives a ratio d 2 / h approximately equal to 2.
- the interval specified above constitutes a good compromise to allow to have sufficiently wide tabs 4, while obtaining folds 5 high enough to allow the strips 3 to be brought together according to the new step d 2 desired.
- the width of a tongue is considered at the level of the longitudinal fold that it makes with a continuous lateral strip ES 1 and ES 2 of the ribbon.
- the tabs 4 must have a certain rigidity combined with a certain elasticity, so first of all to be able to be engaged in the throats of a first part 11 of a connector such as shown in Figure 5, when mounting the strip of contacts. Then the ends of the tabs must press enough against the walls inclined grooves 13 in order to maintain the strip of contacts resting against part 11. Too weak width of the tabs could lead to support insufficient contact strip against this part 11 and a risk of disengagement of the strip when the two parts 11 and 12 of the connector are disconnected.
- the ratio h / ⁇ between the height h of the fold and the diameter of curvature ⁇ of the bottom of the cavity 6 of the fold is preferably between 2.4 and 3.2.
- an h / rapport ratio in the interval specified above makes it possible in particular to have sufficiently large curvatures so as not to risk breaking these side bands during pleating.
- a curvature diameter equal to 0.3 mm, which gives an h / rapport ratio approximately equal to 2.8.
- FIG. 4 is shown schematically a form of lamella somewhat different from a more conventional form of lamellae like those of the contact strip of FIG. 2.
- the lamella 3 has a constriction 7 at its median part along the longitudinal axis A of symmetry of the ribbon, in the same way as certain embodiments of the state of the art such as the patent document CH590570.
- This form of strip is suitable so that after the twist of the strip around its axis A T and the bending of its lateral edges to form the contacts, the middle part of the strip cannot be in contact with a part of a connector such as part 11 or 12 visible in FIG. 5.
- each of the two faces of the strip has two contact zones such as Z 1 and Z 2 located on either side of said central part in a symmetrical manner with respect to axis A.
- a contact strip formed from a strip of lamellae such as that shown in Figure 4, is installed in a first part 11 of a connector.
- the contact strip is shown diagrammatically in a cross-sectional view of a strip in a plane perpendicular to the plane of the strip.
- the first part 11 comprises two longitudinal grooves 13 which are designed to block the tabs 4 of the contact strip once it has been installed.
- each groove 13 is deep enough so that the folds 5 of the two lateral continuous strips ES 1 and ES 2 of the ribbon do not abut against the bottom of the groove when the contact strip is compressed between the two parts 11 and 12 of the connector.
- the first part 11 of the connector comprises a flat or cylindrical longitudinal surface 20 against which the contact 3B of the lower face of the strip is kept pressed when the tongues 4 are installed in the grooves.
- the two end portions 21 and 22 which laterally delimit the longitudinal surface 20 relative to the two longitudinal grooves 13 may constitute lateral displacement stops for the contact strip. Indeed, in the event of a friction force in the direction transverse to the contact strip, in particular during the connection or disconnection of the two parts 11 and 12 of the connector, the contact strip tends to move laterally. In the event that the tongues 4 are not rigid enough to limit this displacement, the folds 5 of a continuous lateral strip ES 1 or ES 2 can come into abutment against an end portion 21 or 22 and prevent any further displacement.
- the contact 3A on the upper face of the strip is capable of pressing against a second part 12 of the connector as soon as the two parts 11 and 12 are connected together.
- This second part 12 is shown in dotted lines in its connection position.
- each contact 3A or 3B is made up of two contact zones such as zones Z 1 and Z 2 for contact 3A.
- the contact surface between a face of a strip and a part of a connector is thus substantially increased compared to a more conventional embodiment in which each face of a strip has a single contact area.
- the contact resistance between a contact 3A or 3B and a connector part respectively 12 or 11 can be significantly reduced.
- FIG 6 a contact strip similar to that shown in Figure 5 is shown partially and schematically by a sectional view cross.
- the connector part that holds the strip includes means for longitudinal locking of the tape, which can be beneficial for some relatively marginal achievements.
- These means are made up of slots 14 which correspond to zones shallower depth of the longitudinal groove 13, the bottom of a niche 14 then being formed by the bottom of throat 13.
- the bosses of these slots are provided to be closer to the plane P of the ribbon than the are the bosses of the folds 5 once the strip has been square.
- Figure 6a is shown schematically a view in longitudinal section of the device of Figure 6 along the plane P '.
- the bottom of the groove 13 is far enough away from the folds 5 so as not to touch when the contact strip is compressed. he clearly appears that the folds 5 can come up against on the sides of the slots 14 in the event of displacement longitudinal of the strip.
- the band can be fitted in this part of connector by being securely locked in the longitudinal direction.
- This of course implies a blocking in rotation of the strip if the connector has a cylindrical shape.
