Definitions
- the present invention relates to a connector m & the disconnectable for communication network.
- transmission networks using multiline cables such as for example networks, local or not, which allow computer data transmissions or digital telephone data transmissions. It is essential to be able to connect in branch and / or in series on each of these networks and in a simple way, one or more terminal equipment for processing computer and / or telephone data, depending on the type of network considered.
- a male connector which makes it possible to connect, by means of the lines of a communication cable, a computer and / or telephone terminal to a network, by inserting this male connector into a female connector having its connection terminals connected to this network, is described.
- European patent application No. 0366556 filed on October 26, 1989.
- This patent application more precisely describes a universal connection assembly for connecting a processing terminal to a data transmission network.
- This universal set includes a male connector and a female connector.
- the connector m & le notably comprises a parallelepipedal insulating support having two lateral faces, an upper face, a lower face, a front face and a rear face, and connection terminals partially embedded in the support and opening onto one of the upper or lower faces.
- terminals are connected to lines of a communication cable surrounded by an insulating sheath and entering the support by its rear face.
- the male connector connection terminals respectively come into sliding contact with corresponding terminals of a female connector.
- These terminals of the female connector are located in a housing and are respectively connected to lines of a communication network.
- the contacts between the terminals of the male connector and the female connector are established when the male connector is inserted in an input window cutting out a front face of the female conductor housing.
- This entry window has edges which are respectively parallel to the faces of the insulating support of the connector m & le.
- the insulating support described in this patent application also comprises a rigid elastic tongue for locking the position of the connector m & le.
- male connectors of this type are very small in size and ensure good locking of the position of male connector in the female connector.
- m & connectors are monoblocks or can be considered as monoblocks: that is to say that, during normal use, the connector part m & le is indefinable.
- human action is essential.
- the connector m & the rest therefore connected to the female connector during a pull on the cable, with all the very important consequences which can ensue therefrom: risk for a person of tripping because of the cable and of falling by being injured, and resulting in his move an expensive device like a computer, or a measuring device.
- a French patent application n ° 90 08831 filed on July 11, 1990 describes a male connector for computer and / or telephone communication network, of the type described above, which includes a pin engaging under the rigid elastic tongue and connected to the cable. , to release the tongue, when pulling on the cable, when the male connector is inserted in the female connector.
- This connector therefore allows in the event of untimely traction on the cable which connects the male connector to a device, when this connector is engaged in the female connector, to facilitate its disconnection, but the connector structure is quite complicated to produce.
- the prior art male connectors provide electrical contact between a contact and a wire, corresponding to a line of the communication cable, by displacement of the contact and perforation of the wire insulation. They therefore have several drawbacks:
- the object of the invention is to solve the disconnection problems during untimely pulling on the cable by proposing a simpler and less expensive solution.
- the invention relates in fact to a connector m & the disconnectable for communication network comprising means of connection between on the one hand the wires corresponding to the lines of a communication cable and on the other hand the terminals of a female connector, which are connected to the lines of the communication network, when inserting said connector m & le into the female connector, and means for locking the connector m & le to the female connector, characterized in that the locking means can be released during traction on the cable.
- the locking means comprise a connection head provided with at least one cavity.
- the connection means comprise a body provided with a lug which enters said cavity so as to allow the positioning of these means between them.
- the connection head comprises two lateral tabs each having an inclined face close to its end.
- the body includes two inclined side walls on which are supported respectively the inclined faces of the two tongues when these two means are made integral.
- Such a connector has many advantages, and in particular: - it makes it possible to reduce the number of parts used by increasing the functions of each,
- the invention also aims to solve the other problems by separating the functions; electrical contact with the terminals of the female connector, fixing on the insulating support, electrical contact with the wires of the cable, and in particular using a new way of making the contacts with the wires of the communication cable.
- connection means comprise on the one hand means for connection to said wires of the communication cable, and on the other hand means of contact, by sliding, with the terminals of the female connector.
- these means of connection to the wires of the communication cable are associated with means of blocking the cable so that the wires cannot move.
- this connector comprises a support containing the contact means and a cover comprising these connection means, which adapts above said support so as to make the connection between the contact means and the connection means, by pushing in one over the other.
- the contact means comprise fork-shaped contacts corresponding respectively to each wire, each contact being located below the end of a wire so that when the cover is pressed on the support, each end of wire is crimped into the fork of a contact.
- Each contact comprises at least two branches each provided, on its internal face or faces, with at least one asperity intended to tear the sheath of the corresponding wire and thus to make contact with the core thereof.
- These fork-shaped contacts are attached to the surface of a printed circuit comprising printed tracks making it possible to make contact with the respective terminals of the female connector.
- the connector according to the invention comprises a support provided in its front part with a cavity in which the printed circuit can be arranged, which then rests, in its front part on inclined walls, and in its rear part on lugs , this cavity opening towards the outside by guide grooves making it possible to correctly position the connector m & le in a corresponding female connector.
- the cover comprises connection means comprising a crimping part provided with several housings into which the ends of the wires of the communication cable are introduced.
- This cover is provided with a rear part, through which the end of the cable can be inserted, the sheath of which has been removed to release the end of the wires; this rear part being connected to a front part, provided with housings to receive these ends of wires, by an inclined scope.
- this cover is provided with two side walls provided with internal racks between which can be introduced a cable locking piece, provided with external racks provided to adapt to the internal racks of the cover.
- This blocking part also comprises, on each of its lateral faces, a lug designed to move in a groove made in the middle part of each internal rack of the cover.
- the cover has lateral slots allowing it to adapt to the walls of the support, and vertical grooves provided to fit respectively on vertical projections located on the lateral faces of said support.
- An advantageous distribution of the connector parts of the invention based on two functions, comprises:
- the elements used for mechanical locking which are the cable blocking part, the cover fitting into the support to close the assembly: these parts can be made of metallized plastic so that there is continuity with the cable shield and the nth point, for example the ninth point, of the female connector.
- connection part locates the wires of the cable in the housings
- connection head positions the contacts of the female connector facing each track of the printed circuit.
- connection elements can be made of transparent insulating plastic material in order to visualize the various connection elements, such as the position of the wires in the connection part, or even the positioning of the printed circuit in the connection head, the latter being unable to be conductive under pain to link the tracks together, in which case we would have a common electrical point, contrary to what is sought and which is to obtain the transmission of, for example, eight independent lines.
- a connector having such characteristics has many advantages, and in particular:
- each contact point is fixed before the crimping of the wires by a means requiring only very moderate efforts.
- the holding of the contacts is carried out by a means without mechanical deformation of material, for example bonding overmolding or soldered on a printed circuit.
- each fork-shaped contact is the first end of a connection terminal partially embedded in the support, and the second end of which makes contact with the respective terminals of the female connector.
- FIG. 1 schematically represents a data transmission network in which a connector according to the invention intervenes
- FIG. 2 schematically represents a longitudinal connector of the prior art connector, in the position inserted in a female connector
- FIG. 3 shows schematically and in exploded perspective and partial section of the connector m & the of the invention
- FIG. 4 represents a view in longitudinal section of the connector m & le of the invention, in two positions of the cover, and in two positions of the front part of the support,
- FIG. 1 schematically represents a data transmission network between two stations 2, 3 communicating by means of a multiline cable.
- the connection assembly 4 makes it possible to connect, in diversion to this network, by a connection cable 5, another terminal or another station 6.
- This connection assembly comprises a female connector connected to two successive sections 7, 8 of the cable network communications, and the male connector of the invention connected to the connection cable 5.
- the connection cable 5, like the cable sections 7, 8 of the network transmission, is preferably a multiline cable with ground shielding. It can, for example, contain eight conductive lines each consisting of a conductor surrounded by an insulating sheath. It can also include a mass shield, constituted for example by a metallic envelope wound around the lines.
- a male connector for communication network computer and / or telephone of the prior art is shown schematically and in longitudinal section in FIG. 2.
- This connector comprises a parailakipilvesdique insulating support 20.
- Connection terminals 21 are partially embedded in the support 20 and lead to the upper face of the support. These terminals are connected to wires 22 forming the lines of a communication cable 23 surrounded by an insulating sheath and entering the support 20 via its rear face 24.
- connection terminals 21 of the male connector respectively come into sliding contact with corresponding terminals 25 of a female connector.
- the terminals of the female connector are enclosed in a box 26 and are respectively connected to lines of the communication network.
- the housing of the female connector has an entry window which allows the insertion of the male connector.
- the support 20 shown in Figure 2 also includes a rigid elastic tongue 27, made integral with this support, in the vicinity of its lower and front faces by a base 28 wider than the tongue 27.
- This tongue 27 and this base 28 are inclined relative to the underside of the support 20 and engage in a corresponding cutout of the front face of the housing 26.
- the base 28 has a transverse locking shoulder 29. To facilitate insertion of the male connector into the female connector , the base 28 and the shoulder 29 can be connected by an inclined surface.
- the shoulder 29 is also preferably inclined, as shown in the figure.
- the tab 27 and the base 28 gradually folds down towards the underside of the support 20 by pressing and sliding this base and the inclined surface on the edges of the cutout 30.
- the tongue 27 and the base 28 move away from the underside of the support 20 to lock the position of the male connector by pressing the shoulder 29 on an internal wall of the front face of the housing 26.
- the connector further comprises a jumper 35 of insulating material for example, which encloses the support 20, in the vicinity of the rear face 24 of this support.
- This jumper partially covers the lateral faces and the upper face of the support, in order to press the end 36 of each wire 22, of the communication cable 23 present inside the support 20; this support ensures the respective contacts between the ends of the wires and the corresponding terminals of the connector m & le.
- Each connection terminal 21 has, on the side of the rear face 24 of the support 20, a pointed shape allowing, thanks to the support of the jumper 35 on the line 22, to perforate the insulation surrounding this wire up to the conductor surrounded by this insulator; the terminal and the wire conductor are then in contact.
- the jumper 35 is held on the support 20 for example by means of lights 37 made on the lateral faces of this jumper and which engage on bosses 38 present on the lateral faces of the support 20.
- the jumper 35 ensures effective blocking of the wires 22 of the cable 23.
- the lateral faces of the support 20 are at least partially metallized in the vicinity of the respective contacts between the connection terminals 21 and the ends 36 of the wires of the cable, to form a shielding sheath which is connected to a sheath metal cable shield. This shielding is able to come into contact with a shielding sheath surrounding the terminals of the female conductor, inside the housing 26.
- the shielding of the female connector is itself connected to a shielding sheath of the lines of the network.
- the connector of the invention makes it possible to separate on the one hand the functions: connection and locking and on the other hand the functions electrical contact with the terminals of the female connector, fixing on the support in insulating material, contact electric with the wires of the cable.
- the male connector of the invention comprises two parts: - a support housing 40 comprising two parts 80 e ⁇ insulating material and 81 made of metallized material which can be separated, the first part 80 being provided in its lower part of a rigid elastic tongue
- the support housing 40 comprises in its front part 80 a cavity 45 in which a printed circuit 46 can be arranged which then rests in its front part on inclined walls 47 of the front part 80, and in its rear and central parts on lugs 48 and 48 ′ of the rear part 81. In its rear part, the printed circuit 46 is inserted into the groove 78 of a stop 79 secured to the body 81.
- the cavity 45 opens outwards through guide grooves 49 making it possible to properly guide the contacts of the female connector towards the contacts of the corresponding printed circuit 46.
- the housing 40 therefore consists of two parts: a part 80 or connection head and a part 81 or body, which can be fully metallized thus ensuring the protection of the data transmitted against the emissions of electromagnetic waves or static electricity.
- connection head 80 has a cavity 82 making it possible to receive a lug 83 of the body 81. This lug makes it possible to position the two parts between them.
- the printed circuit 46 provides between the two parts 80 and 81 a transverse guide.
- the retention of the part 80 on the part 81 is achieved by the tongues 84 and 85. These tongues bear on inclined faces 86 and 87 of the part 81 via the faces 88 and 89 so as to allow this maintenance.
- the connector In normal operation, the connector cannot move back, it is locked in the retracted position by a stop on the female connector which bears on one face 51 of the tongue 41.
- a pull on the connector cable makes the male connector and the connector integral female.
- the tongue 41 is made integral with the support by a flat base 50, wider than the tongue. This tongue 41 and this base 50 are inclined.
- the base 50 which connects the tongue 41 to the support 40 has a transverse shoulder 51 allowing, at the end of insertion, the locking of the male connector in the female connector which has not been shown in FIG. 3, but which appears diagrammatically in figure 2.
- the cover 42 has a rear part through which the end of the cable 44 can be introduced, the sheath of which has been removed to release the end of the wires 43.
- the cover 42 joins the part 91 provided with housings 70 for the ends of the wires connected to the rear part by an inclined span 52.
- the cover 42 comprises two side walls provided with internal racks 53 between which can be inserted a blocking piece 54 of the cable, provided with external racks 55 provided to adapt to the internal racks 53 of the cover 42.
- This piece 54 also includes, on each of its lateral faces, a lug 56: designed to move in a groove 57 made in each rack of the cover 42.
- the cover 42 has lateral slots 60 allowing it to adapt to the walls of the support 40. It also comprises vertical grooves 61 intended to come to be fitted respectively on vertical projections 62 situated on the lateral faces of said support 40.
- the m & connector therefore forms a deformable assembly which can be split into two: part 80 which includes the tongue 41 and the body 81.
- part 80 which includes the tongue 41 and the body 81.
- the male connector being in the assembled position shown in FIG. 4, the faces 88 and 89 of the connection head 80 are in contact with the faces 86 and 87 of the body 81.
- a pull on the cable plates the m & le connector on the female connector via the surface 51, a tensile force tends to spread the parts 80 and 81 apart.
- the bearing faces (86, 87, 88, 89) between these two parts are inclined to effort.
- the latter can be broken down into a component parallel to the tensile force and a component perpendicular to the tensile force.
- the perpendicular component tends to bring the two tongues 84 and 85 closer to one another and therefore to allow the part 80 to separate from the part 81, and therefore from the assembly of the connector m & le.
- the printed circuit 46 as shown in FIG. 5 comprises conductive tracks 64 at the end of which contacts 65 in the form of forks, for example with three branches 66 can be introduced into metallized holes 67. These contacts are arranged in staggered along two transverse lines.
- Each contact 65 comprises at least two branches 66 each provided on its (or its) internal face (s) at least one roughness 68 intended to tear the sheath of the wire 43 and thus make contact with the core of the wire.
- the cable 44 can comprise a screen and a drain, a non-insulated wire which runs along the screen; the cover 42, the part 81 of the support 40 and the blocking part 54 can then be metallized and electrically connected by contact to this screen and to this drain in order to protect the transmission of data from the emissions of electromagnetic waves or electricity static.
- FIGS. 3 and 4 the support 40 and the cover assembly 100 are shown in two distinct and consecutive positions: in a first position in which they are separated, in a second position in which they are made integral one of the 'other.
- the elements serving for the mechanical blocking which are the blocking of cable 54, the cover 42 fitting into the support 81 to close the assembly.
- These parts can be made of metallized plastic so that there is continuity with the shielding of the cable and the nth point, for example the ninth, of the female connector.
- connection 91 locates the wires 43 of the cable 44 in the housings 70
- the part 80 positions the contacts of the female connector facing each track of the printed circuit.
- These parts can be made of transparent insulating plastic material in order to visualize the various connection elements, such as the position of the wires in part 91, or even the positioning of the printed circuit in part 80, the latter being unable to be conductive on pain of connecting the tracks between them, in which case there would be a common electrical point, contrary to what is sought and which is to obtain the transmission of, for example, eight independent lines.
- the contacts 65 are welded, here eight in number, on the printed circuit 46, as shown in FIG. 5. This assembly is placed on the lugs 48 and 48 'of the part 81 to come into abutment in the groove 78 of the piece 79. The pieces 80 and 81 are then assembled to form the support box 40.
- Cable 44 is prepared: Cable 44 is put at the correct length. The sheath is cut over a certain length. The shielding screen and the cable drain 44 are turned over on the cable. The wires 43 of the cable 44 are then positioned according to a color code relating to the installation or to a particular function to be fulfilled.
- the part 91 is guided in the cover 42 by lateral pins which move in grooves in the cover 42 not shown in the figures.
- the connection between these two parts 91 and 42 is achieved by the deformation of a triangle-shaped lug 92, for example, which is provided with the part 91 on its upper part, inside a cylindrical housing 93 of the cover 42 This assembly is carried out by force.
- the points of the triangle interfere with the wall of the cylindrical housing, hence deformation of the triangle, and sufficiently important connection of these two parts,
- the wires 43 are put in place: The wires pre-positioned with respect to each other are introduced into the housings of the part 91.
- the cable 44 is blocked by means of the blocking piece 54.
- This blocking is achieved by a rack-type system.
- this metallized piece 54 and the piece 42 are in electrical contact with each other, and also with the screen and the drain of the cable 44. In this way, electrical contact is ensured between the cable shield and the metallized parts such as 54 and 42.
- the support box 40 and the cover assembly 100 connected to the cable are combined to make the final product a reality.
- the two assemblies are guided relative to each other by the vertical projections 62 of the housing 40 and of the grooves 61 of the cover 42.
- Each wire 43 comes into contact with one of the contacts 65.
- a small effort is then necessary to pierce the insulation and make the core of each wire penetrate between the branches 66 of a contact 65.
- These are the four bosses 72 of part 81 which are housed in four corresponding slots 71 produced in the lateral faces of the cover 42.
- the metallized cover 42 comes into contact with the metallized support 81 and electrical continuity is produced between these two parts and therefore between the support 81 and the cable drain 44.
- Such a connector has many advantages, and in particular:
- the connector m & the thus produced splits into two parts (part 80 on one side, part 81, printed circuit 46 and cover assembly 100 on the other) during an untimely pulling on the cable 44.
- the upper face of the printed circuit which includes tracks ensuring contact with the female connector, allows a frank and precise positioning of the contact surface with respect to a connection reference defined in the standard.
- the fixing of the contacts in the support is carried out by a method without constraint for example gluing, filling of resin, welding; therefore, no stress is exerted on the connector and the deformation seen from the end is zero.
- connection effort is no longer added to the contact fixing effort.
- connection with the wires of the cable being carried several millimeters behind the front face of the connector, it is possible to use wires with diameters on different insulation. Indeed, the standard fixes the width of the connector, but at a certain level this width is free. We can therefore discard the wire connection areas. We can therefore use wires with lower number gauges.
- these wires can be single-strand or multi-strand.
- the contact can be made by a connection terminal, of the same type as that shown in FIG. 2; this terminal then having its rear end in the form of a fork with several branches, so that the corresponding wire can be crimped in the manner shown in particular in FIG. 5.
