Definitions
- the present invention relates to a process for mass production of fuse holder modules, as well as strips of fuse holder modules.
- the invention is generally applicable in all cases where one or more fuses must be installed on a circuit board printed.
- the invention is applicable more particularly, but not exclusively for mini-fuses used in industry automotive and intended to be installed on an electronic card, for example on an electronic card of a computer on board a motor vehicle or on a power circuit said PCB circuit, comprising conductive tracks and metallized holes.
- a first known technique to install the fuse (s) on a card printed circuit consists in providing, for each fuse, two contacts which are installed in holes in the printed circuit and soldered in their respective holes. The whole is then placed in an envelope plastic material comprising means for guiding the fuse or fuses install on the printed circuit board. The fuse (s) are installed on said card after welding on the latter of the contact or contacts intended for receive the fuses.
- Such a known technique requires a number relatively large operations (establishment of each of the contacts, soldering of these on the printed circuit board and connection of each of the fuses in the associated contacts), operations which are not not always easy to automate. In addition, this technique prohibits mounting the fuses as SMD components (components with surface mounting).
- Another known technique consists in forcibly inserting the contacts in respective housings of a plastic housing, such so that the connection pins respectively associated with the contacts protrude from one side of the housing. Then the case is presented in front the printed circuit board and the protruding pins of the contacts are inserted into the metalized holes of the printed circuit board and soldered to said holes, for example by wave welding.
- the fuses can be plugged into the housing contacts before or after the welding operation connection pins in the metallic holes of the circuit board printed.
- the object of the present invention is therefore to remedy the drawbacks of the prior art set out above.
- the invention also provides a fuse holder module and a strip. fuse holder modules obtained by the process having one or more many of the features listed above.
- the invention also provides a strip of fuse holder modules of the type comprising a support of insulating material carrying several pairs of conductive parts, one pair per fuse holder module, each conductive part comprising a contact part, which is intended for establishing a detachable electrical and mechanical connection with a connection lug of a fuse, and a connection part which is intended establishing an electrical connection with a printed circuit board, said pairs of conductive parts being spaced along the median axis longitudinal of the bar so that one of the two pieces conductive of each pair is on one side of said median axis and that the other conductive part is on the other side of said median axis, characterized in that the bar contains a shunting element which connects electrically all conductive parts located on one side of said axis longitudinal median.
- the two conductive parts (contacts) of each fuse holder module are trapped in a support insulating material.
- the two conductive parts or contacts of each fuse holder module whether individual or from a strip of fuse holder modules, do not need to be individually inserted into holes in a printed circuit board or in a housing of a common box with several fuses, which simplifies already the operations of installation of fuses on a circuit board printed.
- the invention makes it possible to obtain modules individual fuse holders or fuse holder modules constituting either components to be stitched onto a printed circuit board, either CMS components.
- This offers wider possibilities for techniques that can be used to install fuse holder modules or strips of fuse holder modules on a printed circuit board.
- the fuse holder modules can be packaged so as to be usable by automatic component implantation machines on printed circuit boards.
- the fuses can be easily fitted from automatically on the fuse holder modules before the operation of strip segmentation. This therefore facilitates the work of the manufacturer of the e-cards.
- the method according to the invention leads to a strip of fuse holder modules which contains a shunt element electrically connecting all the conductive parts located in the same side of the longitudinal center line of the conductive metal strip, which is also the longitudinal median axis of the fuse holder module strip, it is then possible to do without a power conducting track on the printed circuit board, or to significantly reduce its length. That also reduces at least one dimension of the circuit board printed and possibly simplify the route of other tracks conductive, or even reduce the length of some of them if they previously had to bypass the power track to avoid any interference with it.
- each conductive part 2 or 3 has a contact part 2a or 3a and a connection part 2b or 3b.
- the contact parts 2a and 3a of each pair of parts conductors 2 and 3 are intended to establish an electrical connection and mechanical detachable respectively with the two connection tabs of a fuse as we will see later.
- the parts of contact 2a and 3a are cut in the shape of a flat lyre.
- Such a form in flat lyre provides high clamping pressure for low displacement, therefore good electrical contact with the connection lugs of the fuse and a strong holding force of said connection tabs between the two branches of each contact part in the form of a flat lyre.
- the connection parts 2b and 3b of each pair of conductive parts 2 and 3 are intended to establish an electrical connection with a circuit board printed as we will also see later.
- the two conductive parts 2 and 3 of each pair of parts conductive are arranged symmetrically on either side of the axis longitudinal median 4 of the conductive metal strip 1 and they extend transversely to said axis.
- Connection parts 2b and 3b of the two conductive parts 2 and 3 of each pair extend one towards the other towards the longitudinal median axis 4, while the contact parts 2a and 3a of the two conductive parts 2 and 3 of each pair extend in opposite directions, each toward a respective longitudinal side of the band 1.
- the cutting of the strip 1 is also carried out in such a way that shunt elements 5 are provided in the middle region of the strip 1 between the pairs of conductive parts 2, 3.
- shunt elements 5 are provided in the middle region of the strip 1 between the pairs of conductive parts 2, 3.
- Each element of shuntage 5 connects four conductive parts belonging to two adjacent pairs of conductive parts 2, 3.
- each shunting element 5 has a part central unit 5a located on axis 4, and four oblique bars 5b to 5e, which connect the central part 5a respectively to four conductive parts 2 and 3 belonging to two adjacent pairs of conductive parts.
- the part central unit 5a of each shunting element 5 may for example have a circular or annular shape, with a hole 6 in the middle, all holes 6 being regularly spaced along axis 4 and being able to serve, so known per se, to the step-by-step training of the band 1.
- the strip 1 After having been cut as described with reference to FIG. 1, the strip 1 can then be subjected to an oxidation treatment and rolled up in the form of a pancake and temporarily stored in waiting to be subjected to the other operations which will be described more far.
- the strip 1 cut and possibly treated against oxidation is then brought successively through a folding station I, a post II for injection molding or insertion, a post III for inserting component and finally an IV segmentation post as shown in the figure 2.
- a folding station I a post II for injection molding or insertion
- a post III for inserting component
- an IV segmentation post as shown in the figure 2.
- the stations I to IV are represented relatively close to each other for the convenience of drawing, these different stations can actually be at a distance substantially larger from each other.
- the strip 1 is folded into a U around two lines of folding parallel to the longitudinal median axis of the strip as shown in figure 3.
- the elements of shuntage 5 remain in the band plane, while the parts of contact 2a and 3a of the conductive parts 2 and 3 stand up perpendicular to said plane on one side thereof.
- the parts of connection 2b and 3b project from the other side of said plane, for example perpendicular to it when parts 2b and 3b are intended to be planted in metallized holes on a printed circuit board.
- station II is a injection molding in which supports 7 made of a material insulating thermoplastic are molded on the strip 1.
- a single support 7 is formed each time on said strip, this last being then advanced each time by a step corresponding to the step pairs of conductive parts 2, 3 along the strip 1.
- the molding station could be arranged to form simultaneously several supports 7 on the strip 1 at each stop thereof in post II. In the latter case, band 1 is advanced each time times of a step corresponding to a multiple of the step of the conductive parts 2, 3 along strip 1.
- station II is a insertion station, in which the strip 1 is inserted into supports which are similar to the supports 7 and which have been previously molded in one insulating thermoplastic material.
- each pair of conductive parts 2, 3 is partially trapped in the support 7 of insulating material, so that the two parts of contact 2a and 3a and the two connection parts 2b and 3b of the pair of conductive parts 2, 3 remain exposed and that each element of shunt 5 remains exposed between two adjacent supports 7, as shown in Figures 2, 4 and 6.
- the supports 7 can then also be interconnected by at at least one connection 9 made of insulating material, molded with the supports 7, as will be seen below with reference to FIGS. 7 to 10.
- the method according to the invention makes it possible to form strips 10 each comprising several fuse holder modules 8.
- two walls of guide 11 and 12 can also be formed in one piece with each support 7.
- the two guide walls 11 and 12 formed on each support 7 stand perpendicular to the plane of the strip 1 outside the branches of the U formed respectively by the contact parts 2a and 3a of the pair of conductive parts 2, 3 partially embedded in the support 7.
- the two walls 11 and 12 are intended to serve as a guide for a fuse or mini-fuse 13 of known type, when the latter is fitted on the fuse holder module 8 in station III.
- Each fuse 13 has, known manner, a body 14 of an insulating material and of shape approximately parallelepiped, on one side of which two protrude flat connection lugs 15 and 16. Inside the body 14 is embedded a conductive element which is electrically connected to lugs 15 and 16 and which is calibrated to melt when it is traversed by a current having a predetermined intensity.
- the width of the gap between the two branches of each lyre-shaped contact part 2a or 3a, where this interval is the narrowest, is dimensioned so as to have a value slightly smaller than the thickness of the connection lugs 15 and 16 of the fuse 13.
- Each of the two guide walls 11 and 12 a when viewed in end, that is to say in the direction of insertion of a fuse 13 between them, the shaped like a shallow U-shaped channel, so that fuse 13 is guided on four sides when inserted between the guide walls 11 and 12 of the fuse holder module 8, while allowing the manipulation of the fuse 13 using pliers.
- another wall 17 can also be formed integrally with each support 7 of so as to stand perpendicular to the plane of the metal strip conductor, between the two contact parts 2a and 3a of each pair of conductive parts 2, 3, as is more particularly visible in Figure 5 and also in Figures 7, 8, 12 and 13.
- This wall 17 is intended to serve as a stop to limit the insertion depth of the fuse 13 in the fuse holder module 8, as can be seen in particular in Figure 5.
- the strip 1 cut, folded and provided with supports 7 molded for the fuse holder modules 8 is segmented using a suitable cut.
- the segmentation operation can then simply consist of completely eliminating the shunting elements 5.
- FIG. 12 it can be seen that the fuse 13 is retained in the fuse holder module 8 by two snap pins 18 and 19 located on the mutually opposite internal faces of the guide walls 11 and 12, at the upper end of these.
- These snap pins 18 and 19 can be formed in one piece with walls 11 and 12 when the molding operation in station II.
- the individual fuse holder modules 8 thus obtained can be for example delivered in bulk, honeycomb, tube, etc., or can be pasted with a predefined spacing step p on a strip flexible 21 covered with an adhesive layer as shown in FIG. 14.
- the strip 21 furnished with modules 8 is then wound up in the form of a wafer usable in an automatic component installation process on a printed circuit board.
- the segmentation operation can be carried out by cutting the two links 9 and the shunt element 5 between two adjacent fuse holder modules 8, all n fuse holder modules, n being a predetermined whole number.
- each shunt element 5 is cut only partially, as shown in figure 8.
- the bars 10 obtained after segmentation only the parts of the elements remain bridge 5 connecting together the conductive parts which are located on the same side of the longitudinal central axis of the metal strip conductor, for example, the conductive parts 2 as shown in the Figure 8.
- the supports 7 of the various modules fuse holder 8 constituting the bar 10 remain interconnected by a part of the shunting elements 5 after segmentation of the strip and cutting of the shunt elements, the connections 9 located between the supports 7 adjacent to the same side of the longitudinal median axis as the remaining parts of shunt elements 5 can be omitted as shown in Figures 8 and 11. This not only saves insulating material, but also to facilitate the operation of segmentation, since there is only one link 9 left to cut between two adjacent fuse holder modules 8 for detaching the bars 10 each other.
- the embodiment of the strip 10 of fuse holder modules 8 shown in Figure 8 is particularly interesting in the case where the fuses 13 installed on the strip 10 are intended to be connected electrically at the same terminal of a current source. In that case, to connect together all the connection parts 2b of the strip 10, it no longer need to provide a power track on the circuit board printed on which the bar 10 is intended to be mounted, and it suffices to connect one of the connection parts 2b of the strip to the circuit printed.
- connection parts 2b and 3b of the conductive parts 2 and 3 extend perpendicular to the plane of the strip 1 as can be seen in particular in FIGS. 3 and 5.
- fuse holder modules are obtained 8 or strips 10 of fuse holder modules 8 in the form of electrical components intended to be planted in metallized holes a printed circuit board, such as card 22 partially shown in phantom in Figure 5.
- connection 2b and 3b can be bent as shown in dashed lines in figure 3 for connection part 2b, so that we obtain, after segmentation of the strip, fuse holder modules 8 or strips 10 of fuse holder modules 8 in the form of surface mount electrical components (SMD components).
