Description

MODULAR FEMALE CONNECTOR FIELD OF THE INVENTION The present invention relates, in general, to modular female connectors designed to be mounted on printed circuit boards, and, specifically, to modular female connectors which contain components for filtering common and differential mode interference, and for eliminating electrical disturbances. high frequency.

BACKGROUND OF THE INVENTION Frequently, electrical devices are subjected to adverse operation when there is radio frequency interference in the electrical lines that connect the devices to, for example, data communication lines. The electrical devices are not only susceptible to such interferences, but also act as a source of them. Consequently, filters must be interposed between the connected electrical devices in order to eliminate the interference and minimize the effect thereof with respect to the operation of the electrical devices.

This interference can cause two types of distortion of the waveform of the power supply circuit, such as, for example, common mode interference, where identical waveforms are printed on the electrical lines that 'connect to the electrical devices, and interferences of differential mode, which appear as voltage differences between the connecting electrical lines. There are circuits that filter the radio frequency interference, but to achieve an effectiveness and optimal cost, it has been found that it is more efficient to treat the two types of interferences independently; that is, to provide a group of electrical components that act as a common mode filter and another group of electrical components that act as a differential mode filter.

As electrical devices are often connected by modular female connectors, it is advisable to build modular female connectors with integral filter components to avoid the need for additional external filter elements.

In addition, it is advisable that modular female connectors that are mounted on printed circuit boards, eliminate electrical disturbances and interference present in the electrical connection between the male connector that receives the female connector and the printed circuit on which the connector is mounted female. For this purpose, it has been suggested that line-ground capacitors be incorporated in the connector in order to provide a low impedance to the high frequencies between the lines and the ground.

A connector of that type is described in U.S. Patent No. 4,695,115 (Talend). Talend describes a modular female connector in which the step capacitors make contact with the contacts in order to pass electrical disturbances and other high frequency signals to ground. The capacitors are ceramic capacitors mounted on the ends (tombstone capacitors) and are coupled at one of their ends to the contacts that the female connector has, in a place that is between the terminal coincidental portion of the contacts and the portion thereof. which makes contact with the printed circuit board. At its other end, the capacitors are connected to a conductive element, which in turn is coupled to a grounding zone of the printed circuit board, so that the capacitors cause the contacts to ground functionally.

One of the disadvantages of the female connector structure of Talend's invention is that the capacitance is limited, since the size of the ceramic capacitors can not be increased without increasing the size of the female connector at the same time. Since it is advisable that the female connector is not very bulky, that it is as small as possible and that it is within industry standards, this female connector of the previous invention is not entirely satisfactory. In addition, the fact that there is a direct connection between the capacitors and the contacts is detrimental to the signal that is trying to pass through the contacts.

OBJECTIVES OF THE INVENTION An object of the present invention is to offer a new and improved modular female connector.

Another object of the present invention is to offer a new and improved modular female connector incorporating antiparasitic filters and pass capacitors.

Yet another object of the present invention is to provide a practical and efficient solution for connecting a capacitor to the path of the electric current by means of a connector, in order to ground the current path.

Yet another object of the present invention is to provide a modular female connector having capacitance means, in which the disadvantages of the modular female connectors of the previous inventions are substantially eliminated.

Yet another objective of the present invention is to provide a modular female connector with capacitance means, the capacitance of which is much greater than the capacitance of the female capacitors of the previous invention, and wherein the size of the modular female connector is small and is within industry standards.

According to the present invention, this and other objects can be achieved by offering a modular female connector composed of a housing, a first group of contacts to make contact with the contacts of a matching male connector, a second group of contacts making contact with the circuit board of the printed circuit board in which the female connector is mounted, a circuit for electrically coupling the contacts of the first group with the contacts of the second group, a capacitor made of flexible sheet material, preferably formed by several folded folds and a metal cover that surrounds the housing, at least partially, and that is electrically coupled to a grounding zone of the printed circuit board where the female connector is mounted. The condenser contains two conductive laminar elements and an intermediate insulating material. The first of the conductive laminar elements of the capacitor is coupled in one of the extreme folds of the capacitor to contacts of the first group, and the second of the conductive laminar elements of the capacitor makes contact with the metal cover in the fold that is in the Another end of the capacitor, so as to ground the first group of contacts through the folded capacitor to eliminate high-frequency electrical disturbances and interference. In a preferred embodiment, the contact coupling circuit includes an element of the circuit board disposed within the housing of the female connector. In order to filter common mode interferences and differentials, several pairs of toroidal coils are mounted on the component of the circuit board in the contact coupling circuit. A first group of the pairs of toroidal coils operates as a common mode filter, and a second group of the pairs of toroidal coils acts as a differential mode filter.

According to another embodiment of the invention, the contacts of the first group of contacts are coupled in pairs, with each other, and each pair of contacts is coupled to a capacitor, such as the above-described folded capacitor, through its respective resistor. The electrical signal from the first group of contacts reaches the capacitor only after having passed through one of the resistors. By means of this construction, the capacitor is constituted as a central point or central mode or central socket for each pair of contacts of the contacts of the first group of contacts, and creates a common mode voltage of zero value at the output terminals of the connector . The fact of interposing a resistor between the capacitor and each pair of contacts of the first group of contacts that make contact with the contacts of the modular male connector,, provides pairs of balanced signals and a balanced circuit without the signal being impaired.

It is also important to say that only one capacitor is needed in the female connector according to the invention, since each of the contact pairs is connected to the capacitor through its respective resistor and the contact coupling circuit. In this way, the need to have several capacitors is avoided.

The female connector housing can have any conventional mounting arrangement for mounting the female connector on a printed circuit board, such as the arrangement described in U.S. Patent No. 5,244,412, the description of which is incorporated herein by reference. reference.

In an eight position female connector, according to the invention, that is, having eight contacts in the first group, adapted to be coupled to a modular male connector having only four signal carrying contacts, only four contacts of the first group are coupled by the contact coupling circuit to four contacts of the second group. The remaining four contacts of the first group that are not used are connected in pairs with each other, and each pair of unused contacts is coupled to the capacitor which acts to ground the unused contacts, thereby filtering the electrical disturbances and the interferences. In this embodiment, a resistor can be used to connect each connected pair of unused contacts to the capacitor, in addition to using a resistor between the coupled pairs of the contacts used in the first group and the capacitor, in order to achieve a balanced circuit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to Figures 1-7 of the drawings, wherein like reference characters designate identical or corresponding parts in the various views, an embodiment of a device according to the present invention in the form of a female connector. Modular 10, adapted to connect an electronic device to the circuit of a printed circuit board with a modular male connector, includes a housing formed by two parts 14 made of an insulating material, such as plastic, a first group of conductive contacts that includes a plurality of of contacts 12 ?, ..., 12n, a second group of contacts 54 ?, ..., 54m, a circuit board assembly 13a including a circuit for electrically coupling the contacts 12 of the first group to the contacts 54 of the second group, a capacitor 15 made of flexible laminar materials formed by a plurality of folded folds 15 ?, ..., 15x and a cover Tile 17 surrounding, at least partially, the housing 14. The housing 14 includes a first interior portion 16 of the housing and a second exterior portion 18 of the housing, which together define a receptacle 19 adapted to receive a modular male connector. A portion of the branch circuit 12a of each of the first contacts 12? ..., 12n makes contact with the respective contact of the modular male connector that is inserted into the receptacle 19. With reference to Figures 1, 4, 5 and 6, the inner part 16 of the housing is made of insulating plastic material and is substantially L-shaped, including a frame section constituted by a transverse base 20 and by a pair of side portions 22 projecting in a manner ascending from both sides of the portion constituted by the base 20 (Figure 1), and a guiding section 24 extending forward, cantilevered, from the upper part of the section constituted by the frame. The rear side of the frame section of the inner part 16 of the housing is partially closed by a pair of transverse walls 25, one upper and one lower, which extend between the side portions 22. A fairly open space is defined on the side rear of the frame section of the inner part 16 of the housing, between the upper and lower walls 25. A plurality of substantially parallel grooves or guide channels 28 are formed in the upper surface 30 of the guide section 24 of the part 16 internal of the housing, and each channel 28 receives a portion of a branch circuit 12b of one of the contacts 12 ?, ..., 12n (Figure 1). Each channel 28 opens at its rear end 32 in the open upper part of the frame section of the inner part 16 of the housing and ends at its front end 34, which is recessed towards the rear part of the front edge 36 of the section guide 24 for forming the projections 38. As best seen in Figures 1 and 4, each of the first group of contacts 12 ?, ..., 12n has a first branch circuit 12a extending through - of the receptacle 19 formed inside the housing 14 to make contact with one of the respective male contacts. The second branch circuit 12b of each of the contacts 12?, ..., 12n is placed in one of the respective channels 28. The rear end of the second branch circuit 12b of each contact 12 is connected, for example, with solder, to a component 13 of the circuit board of the circuit board assembly 13a. The upper end of each contact 54 ?, ..., 54m, of the second group of contacts is connected to the component 13 of the circuit board, and each second contact 54 extends through a respective hole 26 formed in the portion of the base 20 for connecting at its lower end to the printed circuit board 4 (Figure 4).

The contact coupling circuit that couples the contacts 12 of the first group to the contacts 54 of the second group is located within the frame section of the inner part 16 of the housing. The contact coupling includes the component 13 of the circuit board having a printed circuit that includes a contact element 76 and four pairs of toroidal coils 70a, 70b, 72a and 72b that are mounted on one side of the component 13 of the card of circuits. Each of the pairs of toroidal coils 70a and 70b contains a toroidal core 74b, and around coils 74b are coiled two coils 71 and 73. Each of the pairs of toroidal coils 72a and 72b contains a toroidal core 74a, and around the core 74a two coils 77 and 79 are wound. With reference to Figures 5 and 7, one end of coil 71 of the pair of toroidal coils 70a is connected to contact 12 ?, and the other end of coil 71 is connected to the contact 122. In this way, contacts 12? and 122 are coupled to each other by means of the coil 71. Similarly, the contacts 127 and 128 are coupled to one another by means of the coil 71 of the pair of toroidal coils 70b. The other coil 73 of each of the pairs of toroidal coils 70a and 70b is connected at one end to a coil 79 of one of the respective pairs of toroidal coils 72a and 72b, and its other end is connected to the coil 77 of one. of the pairs of respective toroidal coils 72a and 72b. The coils 77 and 79 are connected at their other ends to the respective contacts 54 of the second group of contacts, that is, the coil 79 of the pair of toroidal coils 72a is connected to the contact 54 ?, the coil 77 of the pair of toroidal coils 72a is connected to the contact 542, the coil 79 of the pair of toroidal coils 72b is connected to the contact 543, the coil 77 of the pair of toroidal coils 72b is connected to the contact 544. In this way, as can best be seen in the circuit diagram shown in Figure 7, the contacts 54 are coupled in pairs with one another through the coils 77 of the pairs of toroidal coils 72a and 72b, which are connected to the coils 73 of the pairs of toroidal coils 70a and 70b, which in turn are connected to the coils 79 of the pairs of toroidal coils 72a and 72b. The coils 71 and 73 are wound around their respective toroidal cores 74b in a specific manner, and are incorporated into the contact coupling circuit so that their inductive flows induced by the current are added. As such, the pairs of toroidal coils 70a and 70b act as differential mode filters. The coils 77 and 79 of the pairs of toroidal coils 72a and 72b are wound around the toroidal core 74a inductively opposite one another, and have the same number of turns so that their current-induced fluxes cancel out substantially, between they. In this case, the pairs of toroidal coils 72a and 72b act as common mode filters. The pairs of toroidal coils 72a and 72b are smaller than the pairs of toroidal coils 70a and 70b since although the pairs of toroidal coils 70a and 70b must conform to the ETHERNET specifications and have a minimum inductance value, there is no industry industry standard specification for the pairs of toroidal coils 72a and 72b that act as common mode filters. With respect to how the coils are arranged in the toroidal cores to form pairs of toroidal coils that act both as common mode filters and as differential filters, reference is made to U.S. Patent Nos. 3,996,537 and 4,263,549. The specifications of these references are incorporated by reference. As can be seen more clearly in Figures 1 and 3, the condenser 15 is a continuous, laminar and flexible elongated assembly formed by a laminate of a plate 170 of an insulating material such as the CAPTON ™ and a pair of conductive lamellae 172a and 172b formed by a metal fabric attached to the respective sides of the plate 170 with a conductive adhesive material such as the conductive paste 171. An insulating coating 173, such as a non-conductive paste, is applied to the outer surface of both laminar elements 172a and 172b, exposing areas of the first and last fold. In the illustrated embodiment, the laminar assembly of the capacitor was folded to form seven substantially equal bent sections or folds 15 ?, ..., 15x, where 1 = 7. A bare area of the conductive web 172a of the first fold 15? it is adjacent to the contact element 76 which is disposed on the component 13 of the circuit board, and is attached thereto, and one of the exposed areas of the conductive web 172b of the last fold 157 is attached to an inner surface of the cover metallic 17 (Figure 4). Although the laminar assembly of the capacitor of the illustrated embodiment has six folds that define seven folds, the number of folds of the capacitor 15 will depend on the capacitance to be obtained and the dimensions of the conductive laminar elements 172a and 172b, and on the 170 plate of insulating material. In this way, the capacitor 15 can even be a flexible, unfolded laminar assembly, provided that the capacitance provided by it is sufficient to allow effective operation of the connector. The capacitor 15 must have an odd number of folds, for example 'seven, as shown, in order to maintain the correct polarity to ground; that is, the web 172a must be electrically coupled to the circuit that is coupled to the contacts 12, and the web 172b must be electrically coupled to the metal cover 17. By having this structure the capacitor 15, as a flexible laminar assembly formed by several folded folds, it offers important advantages in the construction and operation of the connector 10. In particular, it allows a significant increase in the capacitance that can be supplied in the small space occupied by the capacitor and that exists inside the connector. In an experimental embodiment, a capacitance greater than 100 Pf was obtained by constructing a five-fold capacitor with a 0.340 x 2.0-inch rectified copper plate, with a CAPTON ™ film of 0.4 X 2.0 inches. The thickness of the condenser was about 0.124 inches, the webs 172a and 172b were approximately 0.0016 inches thick, the CAPTON ™ plate 170 was about 0.005 inches thick, the conductive paste layer 171 located between the elements laminates 172a, 172b and CAPTON ™ plate 170 had a thickness of about 0.0014 inches, and a non-conductive paste layer 173 on the exterior surface, of at least one of the webs 172a and 172b, had a thickness of approximately 0.0014 inches. With reference to Figure 6, the assembly 13a of the circuit board component also contains four resistors 78 mounted on an opposite side of the component 13 of the circuit board on the side where the pairs of toroidal coils 70a, 70b are mounted, 72a and 72b. The contact element 76, to which the capacitor 15 is connected by means of a conductive adhesive material, is also arranged on the same side of the component 13 of the circuit board as the resistors 78, and is coupled to the resistors 78 by means of of the circuits of the circuit board 13. The circuit of the component 13 of the circuit board supplies an electrical connection from each of the resistors 78 to the contact element 76 of the capacitor in which the capacitor 15 is mounted. In one embodiment of the invention, a resistor 78 is provided for each pair of contacts 12 of the first group. Each resistor is coupled between each pair of contacts 12 and capacitor 15, so as to provide pairs of balanced signals and a balanced circuit without detrimentally affecting the signal. Figure 7 illustrates a circuit diagram of the components of an eight-position female connector, i.e., a female connector having eight contacts 12 ?, ..., 128 according to the invention, which is adapted to be coupled to a printed circuit board 4 having only four signal carrying contacts. Consequently, only four contacts, 12 ?, 122, 127 and 128 of the first group are coupled by the contact coupling circuit to four contacts of the second group 54?, ..., 544. The four unused contacts 123 and 126 of the first group are connected in pairs, 12 and 124 125 and 126, by means of the corresponding electrical connections of the component 13 of the circuit board, and then each pair is connected to a resistor 78. On the other hand, electrical connections are provided, which could be the wires 75, (as shown in the dotted lines of Figures 5 and 6) for coupling the resistors 78, which are coupled to the contacts 12 ?, 122 , 127, 128, to one of the respective coils 71. In this way, the contacts 123 and 124 are connected to each other and also to a single resistor 78; and, similarly, the contacts 12s, 126 are connected to each other and to another resistor 78. The contacts 123, 124 125 126 are not used and are filtered. The coil 71 of the first pair of toroidal coils 70a connects the contacts 12? and 122, and another coil 71 of the second pair of toroidal coils 70b connects the contacts 127., 128. The wires 75 connect each of the coils 71 to one of the resistors 78. The circuits of the component 13 of the circuit board have connections between each of the resistors 78 and the capacitor 15. In this way all the contacts 12? ..., 128 are electrically coupled to the capacitor 15 by means of the resistors 78. In view of this arrangement, the current path of each pair of the contacts 12 is directed to the capacitor 15 only through one of the resistors 78. , with which 'pairs of balanced signals are supplied. Again with reference to Figure 1, the assembly constituted by the female connector 10 will be described below. Initially, the contacts 12?, ..., 12n are preformed with the first and second portions of the branch circuits 12a, 12b, as shown in Figure 1. The assembly 13a of the component of the circuit board is also preassembled, with its electrical circuit containing the component 13 of the circuit board, and the pairs of toroidal coils 70a, 70b, 72a, 72b, the wires 75, the contact element 76 of the capacitor and the resistors 78 already mounted on the component 13 of the circuit board, and having the attenuation contacts 54 ?, ..., 54m, and the attenuation contacts 54 connected thereto. contacts 12 ?, ..., 12n. After inserting the set 13a of the circuit board in the frame of the inner part 16 of the housing, the attenuating contacts 54 are inserted in the aligned holes 26 that are in the base portion 20 of the inner part 16 of the housing , and the branch circuits 12b of the contacts 12?, ..., 12n are inserted in the respective contacts of the channels 28 that are in the guide portion 24 of the inner part 16 of the housing, so that the first portions 12a of the branch circuit extends beyond the leading edge of the channels 28. Then the subset of the inner part 16 of the housing, the assembly 13a of the circuit board and the contacts 12?, ..., 12n are inserted into the rear space which is inside the outer part 18 of the housing in the direction of the arrow A, as shown in Figure 1. During insertion, the matching portions of contacts, i.e., the first portions of the circuit 12a of the contacts 12?, ..., 12n, are aligned with the respective guide grooves formed in the outer part 18 of the housing which is between the partitions and make contact with a surface, whereby the first portions 12a of the circuit The branches are bent to adopt the shape shown in Figure 4 as the insertion of the inner part 16 of the housing in the outer part 18 of the housing continues. In the aforementioned U.S. Patent No. 5,244,412, other details of the insertion of the inner part 16 of the housing in the outer part 18 of the housing can be found. The recticular plate 172a which is in the first fold 15? of the folded capacitor 15 is electrically connected to the contact element 76 of the component 13 of the circuit board by means of a conductive adhesive material. Then the metal cover is placed on the outer part 18 of the housing 14 so that it surrounds at least a portion of the housing 14 once the capacitor 15, the assembly 13a of the circuit board and the contacts 12 ?, ..., 12n are fastened in the housing 14. To this end, the metal cover 17 is constructed with folds that coincide with the edges of the outer portion 18 of the housing. To apply the metal cover 17 to the housing 14, the first side portion 17a (only one of the portions in Figure 1 is shown) and the front portion 17b (Figure 2) of the metal cover 17 are placed abutting the corresponding surfaces of the exterior part 18 of the housing; that is, the metal cover 17 is placed on the outer part 18 of the housing so that the side portions 17a make contact with the side portions 18a of the housing, and the front portion 17b of the metal cover il makes contact with the front side, substantially open, of the outer part 18 of the housing (see Figure 2). Then, the upper surface 17c of the metal cover 17 comes into contact with the upper surface of the outer part 18 of the housing. A conductive adhesive material is applied to connect the metal cover parts 17 to the outer surfaces of the housing 14. The rectilinear plate 172 of the last fold 15 of the folded capacitor 15 is electrically connected to the rear surface 17d of the metal cover by means of an adherent conductor material. The rear surface 17d of the metal cover 17 is bent in the fold between the rear surface 17d and the upper surface 17c in order to close a rear side of the outer part 18 of the housing; that is, the side of the outer part 18 of the housing that is open, through which the inner part 16 of the housing is inserted into the outer part 18 of the housing and where the condenser 15 is placed. The rear surface 17d of the metal cover 17 is attached to the side portions 17a of the cover 17 by means of the fastening elements 57a, 57b for firmly closing the cover 17 in the housing 14. In this way, only a lower portion of the housing 14 is exposed. and the receptacle 19 for entering the modular male connector (as shown in Figure 2) and are not covered by the metal cover 17. Then, the female connector 10 is attached to the printed circuit board 4 by inserting the uprights 56 in the holes 9 of the printed circuit board 4. The electrical connection of the metal cover 17 to the printed circuit board 4 is made by metal tongues 58 which extend from the bottom surface of the side portions 17a of the metal cover 17. The tabs 58 are soldered with tin to a grounding area that is on the printed circuit board 4, so as to functionally ground the metal cover 17. and being able to ground the first group of contacts 12 ?, ..., 12n coupled thereto by means of the capacitor 15 and the component 13 of the circuit board. The examples given above are not exclusive. For those of skill in the art, many other variations of the present invention will be obvious, which are contemplated to fall within the scope of the appended claims. For example, although in the illustrated embodiment there is a component of the circuit board within the connector, in a simpler embodiment it would be possible to remove the printed circuit board component and the toroidal coil pairs attached thereto, and connect the capacitor folded through the resistors, directly to the contacts or to any other means of electrical coupling that couples the contacts that make contact with the matching contacts of the male connector and the contacts that make contact with the printed circuit board. It is also possible to completely remove the component from the circuit board and mount the pairs of toroidal coils, the resistors, the capacitor and the contact coupling circuit in the housing, for example, in the inner walls thereof.
