Description
La présente invention concerne un dispositif de connexion pour circuit imprimé, comprenant une embase ayant au moins deux contacts mâles parallèles, un cavalier ayant au moins deux contacts femelles parallèles et une fiche ayant au moins deux contacts femelles parallèles, les contacts mâles de l'embase étant enfichables dans les contacts femelles du cavalier et les contacts mâles de l'embase étant enfichables dans les contacts femelles de la fiche.The present invention relates to a connection device for a printed circuit, comprising a receptacle having at least two parallel male contacts, a jumper having at least two parallel female contacts and a plug having at least two parallel female contacts, the male contacts of the receptacle being plugged into the female contacts of the jumper and the male contacts of the base being pluggable into the female contacts of the plug.
Un tel dispositif de connexion est utilisé pour tester des cartes de circuit imprimé et notamment pour détecter des défauts relatifs à la continuité électrique des conducteurs imprimés.Such a connection device is used to test printed circuit boards and in particular to detect faults relating to the electrical continuity of the printed conductors.
Dans un dispositif connu de ce type, le cavalier est un bloc parallélépipédique ayant des contacts femelles qui sont borgnes et dont la longueur est égale à celle des contacts mâles de l'embase. Les deux contacts femelles du cavalier sont reliés électriquement entre eux par un court-circuit inclus dans le cavalier afin de relier normalement deux conducteurs imprimés de la carte auxquels sont soudées des extrémités des contacts mâles.In a known device of this type, the jumper is a rectangular block having female contacts which are blind and whose length is equal to that of the male contacts of the base. The two female contacts of the jumper are electrically connected to each other by a short-circuit included in the jumper in order to normally connect two printed conductors of the card to which the ends of the male contacts are soldered.
Par ailleurs, la fiche dite fiche de test est un bloc parallélépipédique plus long que le cavalier, dans les contacts femelles de laquelle sont enfichés les contacts mâles de l'embase après avoir ôté le cavalier de l'embase. La fiche de test n'est pas ainsi capable de tester la liaison des deux conducteurs imprimés. La fiche teste uniquement chacun des conducteurs imprimés individuellement.Furthermore, the plug known as the test plug is a rectangular block longer than the jumper, in the female contacts of which the male contacts of the socket are plugged in after having removed the jumper from the socket. The test sheet is thus not capable of testing the connection of the two printed conductors. The sheet only tests each of the conductors printed individually.
Par ailleurs, notamment lorsque l'embase, le cavalier et la fiche comportent chacun deux paires de contacts parallèles et juxtaposées, un retournement à 180° du cavalier ou de la fiche autour de la direction des contacts permet de nouveau d'enficher le cavalier ou la fiche dans l'embase. Un tel retournement engendre des erreurs dans les mesures et ne peut être évité qu'en exigeant une attention particulière de l'opérateur lors de la réalisation des connexions.Furthermore, in particular when the base, the jumper and the plug each have two pairs of parallel and juxtaposed contacts, a 180 ° reversal of the jumper or of the plug around the direction of the contacts again makes it possible to insert the jumper or the plug in the socket. Such a reversal generates errors in the measurements and can only be avoided by requiring special attention from the operator when making the connections.
La présente invention a pour but de fournir un dispositif de connexion pour circuit imprimé du type défini dans l'entrée en matière qui permet de relier électriquement les contacts femelles de la fiche aux contacts femelles du cavalier lorsque le cavalier est enfiché dans l'embase afin de tester des conducteurs imprimés reliés par paire à travers le cavalier.The object of the present invention is to provide a connection device for a printed circuit of the type defined in the entry into material which makes it possible to electrically connect the female contacts of the plug to the female contacts of the jumper when the jumper is inserted in the base in order to test printed conductors connected in pairs through the jumper.
A cette fin, le dispositif de connexion est caractérisé en ce que les contacts femelles du cavalier traversent complètement le cavalier et ont une longueur inférieure à la longueur des contacts mâles de l'embase et en ce que les contacts mâles de l'embase sont enfichables dans les contacts femelles de la fiche après l'enfichage du cavalier dans l'embase dont les contacts mâles traversent complètement les contacts femelles du cavalier.To this end, the connection device is characterized in that the female contacts of the jumper completely pass through the jumper and have a length less than the length of the male contacts of the base and in that the male contacts of the base are pluggable. in the female contacts of the plug after the jumper has been inserted into the socket, the male contacts of which completely pass through the female contacts of the jumper.
Grâce à la caractéristique précédente, l'embase, le cavalier et la fiche sont empilés parallèlement aux contacts, ce qui permet de relier les contacts femelles d'une paire de la fiche à deux conducteurs imprimés court-circuités à travers le cavalier.Thanks to the preceding characteristic, the base, the jumper and the plug are stacked parallel to the contacts, which makes it possible to connect the female contacts of a pair of the plug with two printed conductors short-circuited through the jumper.
Selon une autre caractéristique, l'assemblage d'un premier élément du dispositif tel que l'embase, respectivement le cavalier, avec un second élément du dispositif tel que le cavalier ou la fiche, respectivement la fiche, comprend des moyens de détrompage pour partie dans le premier élément et pour partie dans le second élément pour assembler dans le premier élément le second élément à une unique position par rapport au premier élément. Les moyens de détrompage tels qu'une languette longitudinale de l'un des premier et second éléments coopérant avec une rainure de l'autre élément empêche tout assemblage du cavalier avec l'embase, ou de la fiche avec l'embase, ou de la fiche avec le cavalier après avoir effectué un retournement à 180° du cavalier ou de la fiche.According to another characteristic, the assembly of a first element of the device such as the base, respectively the jumper, with a second element of the device such as the jumper or the plug, respectively the plug, includes keying means for part in the first element and partly in the second element to assemble in the first element the second element in a single position relative to the first element. The keying means such as a longitudinal tongue of one of the first and second elements cooperating with a groove of the other element prevents any assembly of the jumper with the base, or of the plug with the base, or of the plug with the jumper after having turned the jumper or plug 180 °.
Selon une autre caractéristique, l'assemblage d'un premier élément du dispositif tel que l'embase, respectivement le cavalier, avec un second élément du dispositif tel que le cavalier ou la fiche, respectivement la fiche, comprend des moyens pour partie . dans le premier élément et pour partie dans le second élément pour verrouiller en translation parallèlement à la direction d'enfichage le second élément dans le premier élément.According to another characteristic, the assembly of a first element of the device such as the base, respectively the jumper, with a second element of the device such as the jumper or the plug, respectively the plug, comprises means for part. in the first element and partly in the second element to lock in translation parallel to the direction of insertion the second element in the first element.

Le dispositif de connexion illustré à la Fig. 1 est relatif à quatre paires de conducteurs imprimés d'une carte CI à tester. A chaque conducteur imprimé est associé un trou métallisé T. Comme montré à la Fig. 1, des premiers trous T à T4 des paires sont alignés le long d'un bord B de la carte de circuit imprimé CI transversalement au dispositif de connexion, et des seconds trous T'1 à T'4 des paires sont alignés parallèlement à la rangée des premiers trous et sont respectivement alignés deux-à-deux avec les premiers trous perpendiculairement au bord B. Les trous sont écartés typiquement au pas p = 2,54 mm.The connection device illustrated in FIG. 1 relates to four pairs of printed conductors of a CI card to be tested. Each printed conductor is associated with a metallized hole T. As shown in FIG. 1, first holes T to T4 of the pairs are aligned along an edge B of the printed circuit board CI transversely to the connection device, and second holes T ' 1 to T' 4 of the pairs are aligned parallel to the row of the first holes and are respectively aligned in pairs with the first holes perpendicular to the edge B. The holes are typically spaced apart at the pitch p = 2.54 mm.
Le dispositif de connexion comprend selon la réalisation illustrée une embase femelle 1 à quatre paires de contacts électriques mâles 211 - 21'1 à 214 - 21'4, deux cavaliers mâles-femelles 31, 32 ayant chacun deux paires de contacts électriques femelles 41 - 4'1 et 42 - 4'2' 4 3 - 4'3 et 44 - 4'4' et deux fiches de test 51, 52 ayant chacune deux paires de contacts électriques femelles 61 - 6'1 et 62- 6'2, 6 3 - 6'3 et 6 4 - 6'4. Les éléments 1, 31, 3 2, 51 et 52 sont en matière plastique.The connection device comprises, according to the illustrated embodiment, a
L'embase 1 a une section longitudinale en U ayant un fond avant 10 à section carrée et des branches arrière 11 et 11' à section carrée. L'embase comporte quatre paires de broches conductrices parallèles 21 - 2'1 à 24 - 2'4 qui sont disposées l'une par rapport à l'autre selon une répartition identique à celle des paires de trous T1 - T'1 à T 4 - T'4 de la carte de circuit imprimé CI. Chaque broche 21 à 24, 2'1 à 2'4 traverse perpendiculairement le fond 10 de l'embase et est fixé au fond 10. Le fond 10 partage chaque broche 21 à 24, 2'1 à 2'4 en une première partie coudée à angle droit 201 à 204, 20'1 à 20'4 dirigée vers la branche inférieure 11 de l'embase, et en une seconde partie rectiligne formant le contact mâle 211 à 214, 21'1 à 21'4 entre les branches 11 et 11'.The
Les extrémités des premières parties coudées 201 à 204 et 20'1 à 20'4 forment des picots qui traversent les trous métallisés T1 à T4, T'1 à T'4 et qui sont soudés respectivement à ceux-ci, de préférence à la vague d'étain, après que la branche inférieure 11 de l'embase soit pressée contre la carte de circuit imprimé entre le bord B et la rangée de trous T1 à T4.The ends of the first bent parts 20 1 to 20 4 and 20 ' 1 to 20' 4 form spikes which pass through the metallized holes T 1 to T 4 , T ' 1 to T ' 4 and which are welded respectively to them, preferably to the tin wave, after the
Selon une autre réalisation, les premières parties des broches 21 à 24, 2'1 à 2'4 sont droites et perpendiculaires au fond 10 de l'embase 1 ; dans ce cas, les cavaliers 31, 32 et les fiches 51, 52 s'enfichent perpendiculairement à la carte de circuit imprimé CI.According to another embodiment, the first parts of pins 2 1 to 2 4 , 2 ' 1 to 2' 4 are straight and perpendicular to the
Les contacts mâles 211 à 214 et 21'1 à 21'4 sont disposés parallèlement aux branches 11 et 11' et ont une longueur sensiblement égale à la longueur L3 des branches 11 et 11'. La première rangée de premiers contacts 211 à 214 est au-dessus de la branche inférieure 11 et à une distance de celle-ci égale à la distance entre la seconde rangée de premiers contacts 21'1 à 21'4 et la branche supérieure 11'.The
Entre les deux premières paires de contacts mâles 211 -21'1 et 211 - 21'2 et entre les deux dernières paires de contacts mâles 213 - 21'3 et 214 - 21'4, la face interne de la branche inférieure 11 de l'embase comporte deux languettes 121 et 122 parallèles aux contacts mâles. Au niveau du bord transversal de la branche supérieure 11' de l'embase, la face interne de la branche 11' comporte une languette transversale 13 perpendiculaire aux contacts mâles.Between the first two pairs of male contacts 21 1 -21 ' 1 and 21 1 - 21' 2 and between the last two pairs of male contacts 21 3 - 21 ' 3 and 21 4 - 21' 4 , the internal face of the branch lower 11 of the base comprises two tongues 12 1 and 12 2 parallel to the male contacts. At the transverse edge of the
Chaque cavalier 31, 32 a une section longitudinale en U et est composé d'un bloc parallélépipédique avant 301, 302 et de deux branches arrière 311 et 31'1, 312 et 31'2. Chaque bloc 301, 302 de cavalier contient deux paires de contacts femelles 41- 4'1 et 42- 4'2, 43- 4'3 et 44 - 4'4 qui sont propres à recevoir les paires de contacts mâles 211-21'1 et 212 - 21'2, 213- 21'3 et 214 - 21'4 respectivement lors de l'assemblage du cavalier et de l'embase. Chaque contact femelle d'un cavalier est formé par un fourreau en lames métalliques traversant longitudinalement de part en part le bloc du cavalier.Each jumper 3 1 , 3 2 has a longitudinal U-shaped section and is composed of a front parallelepiped block 30 1 , 30 2 and two
Chaque bloc 301, 302 d'un cavalier forme avec des premières parties 321 et 32'1, 32 2 et 32'2 des branches 311 et 31'1, 312 et 31'2 du cavalier, une partie mâle ayant des profils externes longitudinaux et transversaux complémentaires des contours internes longitudinaux et transversaux d'une moitié de l'embase 10 contenant deux paires de contact 211 - 21'1 et 212-21'2, 213-21'3 et 214 - 21'4. Ainsi, dans la face inférieure de chaque cavalier 31, 32 est ménagée une rainure borgne centrale longitudinale 341, 342 pour recevoir la languette respective 121, 122 de l'embase, et à l'extrémité supérieure de la première partie 32'1' 32'2 de branche du cavalier est ménagée une rainure transversale 351, 352 pour recevoir une moitié de la languette transversale 13 de l'embase. La longueur L3, la largeur ℓ3 et la hauteur H3 de la partie mâle 30 1 - 32 1 - 32'1 , 30 2 - 32 2 - 32'2 de chaque cavalier sont respectivement égales à la longueur et à la demi-largeur des branches 11 et 11' de l'embase, et à l'écartement entre les branches 11 et 11'. Puisque la longueur des contacts mâles 211 à 214 et 21'1 à 21'4 est sensiblement égale à la longueur L3 des branches 11 et 11', des portions d'extrémité des contacts mâles sortent de la face arrière des blocs 301 et 302 sur une longueur égale à celle des premières parties de branche 321, 32'1, 322, 32'2 lorsque les blocs des cavaliers sont enfichés et poussés contre la face interne du fond 10 de l'embase.Each block 30 1 , 30 2 of a jumper forms with first parts 32 1 and 32 ' 1, 32 2 and 32' 2 of the
A ce premier stade d'assemblage comme montré à la Fig. 2, les cavaliers 31 et 32 sont de préférence du type comportant des courts-circuits pour relier respectivement deux-à-deux les fourreaux 41 et 4'1 à 44 et 4'4 des paires et donc les conducteurs imprimés associés aux trous T1 et T'1 à T 4 et T'4. Dans le cas où seulement deux fourreaux tels que les fourreaux 41 et 4'1 du cavalier 31 sont reliés électriquement, l'assemblage de la rainure 341 et de la languette 121 notamment sert de moyens de détrompage afin qu'un retournement à 180° du cavalier ne puisse permettre l'enfichage du cavalier dans l'embase et donc la connexion non désirée des deux autres contacts mâles 212 et 21'2.At this first stage of assembly as shown in FIG. 2, the jumpers 3 1 and 3 2 are preferably of the type comprising short circuits for connecting two-by-two respectively the sleeves 4 1 and 4 ' 1 to 4 4 and 4' 4 of the pairs and therefore the associated printed conductors at holes T 1 and T ' 1 to T 4 and T' 4 . In the case where only two sleeves such as the sleeves 4 1 and 4 ' 1 of the jumper 3 1 are electrically connected, the assembly of the groove 34 1 and the tongue 12 1 in particular serves as polarizing means so that a reversal at 180 ° of the jumper cannot allow the insertion of the jumper in the base and therefore the unwanted connection of the two other
L'assemblage de la rainure 351, 352 de chaque cavalier avec la languette transversale 13 de l'embase sert de moyens de détrompage et également de moyens de verrouillage en translation longitudinale des cavaliers dans l'embase suite au rabattement de la branche flexible supérieure 11' de l'embase après l'introduction du bloc de cavalier 301, 30 2.The assembly of the
Chacune des branches 311, 31'1, 312, 31'2 des cavaliers 31, 32 est composée de la première partie 321, 32'1, 322, 32'2 déjà mentionnée et d'une seconde partie d'extrémité 331, 33'1, 332, 33'2 en saillie vers l'extérieur. La distance entre les secondes parties de branche de chaque cavalier est égale à l'écartement H3 entre les branches 11 et 11' de l'embase 1. Les faces externes 361, 36'1, 362, 36'2 des secondes parties de branche des cavaliers sont crénelées transversalement afin de faciliter la préhension des cavaliers. Sur la face interne de la seconde partie inférieure de branche 311, 312 de chaque cavalier 31, 32 est prévue une languette longitudinale centrale 371, 372 ayant une section transversale identique à celle des languettes transversales 121 et 122 sur la branche inférieure 11 de l'embase 1.Each of the
En se référant à nouveau à la Fig. 1, chaque fiche de test 51, 52 a une forme générale parallélépipédique et comporte un bloc parallélépipédique avant 501, 502, une portion intermédiaire mâle 511, 512 et une portion arrière longiligne 521, 522.Referring again to FIG. 1, each test sheet 5 1 , 5 2 has a generally parallelepiped shape and has a parallelepiped block before 50 1 , 50 2 , a male
Chaque bloc 501, 502 a des dimensions identiques à l'espace parallélépipédique compris entre les parties de branche 321 et 32'1, 322 et 32'2 de chaque cavalier 31, 32. Ainsi la longueur L5 des blocs 501, 502 est égale à la longueur des premières parties de branche 321 et 32'1, 32 2 et 32'2 des cavaliers, et la hauteur H5 des blocs 501, 502 est égale à l'écartement entre les parties de branche 321 et 32'1, 322 et 32'2 de cavalier et est inférieur à l'écartement H3 entre les branches 11 et 11' de l'embase 1. Chaque bloc 501, 502 contient deux paires de fourreaux conducteurs parallèles 61-6'1 et 6 2 - 6'2, 6 3 - 6'3 et 6 4 - 6'4, formant contacts femelles, qui sont répartis transversalement d'une manière identique aux fourreaux de chaque cavalier. Comme montré à la Fig. 3, lorsqu'un cavalier, tel que le cavalier 31, est enfiché dans l'embase 1 contre le fond 10, l'introduction à fond du bloc 501 de la fiche associée 51 entre les premières parties de branche 321 et 32'1 est telle que l'ensemble du bloc 301 du cavalier 31 et du bloc 501 de la fiche 51 est complètement contenu dans l'embase 1, la longueur du bloc 301 du cavalier étant égale à (L3 - L5). Les paires de contact mâles 211 - 21'1 et 212 - 21'2 traversent complètement les paires de fourreaux 41- 4'1 et 42 - 4'2 du cavalier 31 et pénètrent dans les paires de fourreaux 61 - 6'1 et 62- 6'2 de la fiche 51 respectivement, sur une longueur sensiblement égale à L5.Each
L'assemblage mécanique du cavalier 31, 32 avec la fiche correspondante 51, 52 est réalisé d'une manière analogue à l'assemblage mécanique du cavalier 31, 32 avec l'embase 1 afin que la fiche 51, 52 puisse également être enfichée directement dans l'embase 1 comme montré à la Fig. 4. A cette fin, la portion intermédiaire mâle 511, 512de chaque fiche 51, 52 a des profils longitudinaux et transversaux analogues aux profils longitudinaux et transversaux de l'espace compris entre les secondes parties de branche 331 et 33'1, 332 et 33'2 de chaque cavalier et analogues aux profils longitudinaux et transversaux de l'espace compris entre les branches 11 et 11' de l'embase sur une longueur (L3 - L5) prise à partir des bords des branches 11 et 11'. Chaque portion intermédaire de fiche 511, 522 a une hauteur égale à H3. Dans la face inférieure de chaque portion de fiche 511, 512 est ménagée une rainure borgne centrale longitudinale 531, 532, représentée en traits interrompus courts dans la Fig. 1, pour recevoir une languette de cavalier 371, 372, ou une languette 121, 122 de l'embase. Dans la face supérieure de chaque portion de fiche 511, 512 est ménagée une rainure transversale 541, 542 pour recevoir une moitié de la languette transversale arrière 13 de l'embase, ou éventuellement une languette transversale (non représentée) sous la face interne d'une seconde partie de branche supérieure de cavalier 33'1, 33'2 selon une autre variante de cavalier.The mechanical assembly of the jumper 3 1 , 3 2 with the corresponding plug 5 1 , 5 2 is carried out in a similar manner to the mechanical assembly of the jumper 3 1 , 3 2 with the
La portion arrière 521, 522 de chaque fiche 51, 52 contient quatre fils conducteurs gainés respectivement reliés aux quatre contacts femelles 61, 6'1, 62 et 6'2, 63, 6'3' 64 et 6'4, qui sortent de la fiche à travers un manchon de gaine 551, 552 prolongeant la face arrière de la fiche. Les fils conducteurs isolés sont à relier à un appareil de contrôle et de test de la carte de circuit imprimé CI. L'arrière de la face supérieure de chaque fiche 51, 52 présente un épaulement 561, 562 dont la face supérieure est crénelée transversalement afin de faciliter la préhension de la fiche.The rear portion 52 1 , 52 2 of each plug 5 1 , 5 2 contains four sheathed conductive wires respectively connected to the four female contacts 6 1 , 6 ' 1 , 6 2 and 6' 2 , 6 3 , 6 '3' 6 4 and 6 ' 4 , which exit from the plug through a sheath sleeve 55 1 , 55 2 extending the rear face of the plug. The insulated conductor wires are to be connected to a control and test device on the printed circuit board CI. The rear of the upper face of each card 51 , 5 2 has a shoulder 56 1 , 56 2 , the upper face of which is crenellated transversely in order to facilitate gripping of the card.
Un assemblage de l'embase 1, d'un cavalier tel que le cavalier 31 et d'une fiche telle que la fiche 51 comme montré à la Fig. 3 permet de tester individuellement les quatre conducteurs imprimés associés aux trous correspondants T1, T'1, T2 et T'2, ou de préférence, de tester des liaisons entre les trous T et T'1, T2 et T'2 lorsque le cavalier 31 comporte deux courts-circuits entre les contacts mâles 41 et 4'1 et entre les contacts mâles 42 et 4'2.An assembly of the
L'assemblage direct d'une fiche, telle que la fiche 31, et de l'embase 1 comme montré à la Fig. 4 permet de tester individuellement les conducteurs imprimés associés aux trous T1, T'1, T2 et T'2, et notamment de détecter des coupures dans les conducteurs imprimés.Direct assembly of a plug, such as plug 3 1 , and of the
Plusieurs embases, telles que l'embase 1, peuvent être juxtaposées le long du bord B de la carte de circuit imprimé CI pour former une barrette de connexion.Several bases, such as
Selon d'autres réalisations, une embase peut comprendre plus de quatre paires de contacts mâles, et recevoir plus de deux cavaliers et/ou fiches correspondants. Un cavalier peut comprendre plus de deux paires de contacts femelles. De même, une fiche peut comprendre plus de deux paires de contacts femelles. D'une manière générale, une embase, un cavalier et une fiche selon l'invention comprend chacun au moins deux contacts, tels que deux contacts mâles 21 et 2'1, deux contacts femelles 41 et 4'1 et deux contacts femelles 61 et 6'1, respectivement.According to other embodiments, a base can include more than four pairs of male contacts, and receive more than two jumpers and / or corresponding plugs. A jumper can have more than two pairs of female contacts. Likewise, a plug can include more than two pairs of female contacts. In general, a socket, a jumper and a plug according to the invention each comprises at least two contacts, such as two male contacts 2 1 and 2 ' 1 , two female contacts 4 1 and 4' 1 and two female contacts 6 1 and 6 ' 1 , respectively.
Selon d'autres réalisations, les moyens de détrompage mécaniques entre les trois éléments 1, 31 et 51 d'un dispositif de connexion selon l'invention sont des assemblages réciproques de ceux décrits précédemment. Ainsi, une languette longitudinale 121 de l'embase 1 est remplacée par une rainure longitudinale pour recevoir une languette longitudinale remplaçant la rainure 341 du cavalier 31, ou remplaçant la rainure 531 de la fiche 51; la languette transversale 13 de l'embase 1 est remplacée par une rainure transversale pour recevoir une languette longitudinale remplaçant la rainure 351, du cavalier 31, ou remplaçant la rainure 541, de la fiche 51.According to other embodiments, the mechanical coding means between the three
