Description

-Y — Low-voltage connector designed to be used in a communication system Full Description BACKGROUND The present invention relates to a low-voltage connector designed to be used in a communication system . The invention relates more specifically to a connector of type RI and in particular of type RJ45-© known from US Patent Document No. 17714646 a female connector 2145 specifically comprising a body; For example it is made of two parts. The front face of the connector includes a housing or recess designed to accommodate a compatible male connector. This type of conductor also includes an insulation-displacement Clad support; Accommodates each cable wire contact and a wire regulating carrier placed on the carrier 0 for insulation-offset contacts. It is known that it is necessary to maintain the integrity of transmitted signals in communication systems. to maintain the integrity of the signals at a certain level; It is especially necessary to take into account the interference caused by AS and inductive coupling between signals transmitted on different conductors. Thus the signal being transmitted on a conductor is capable of interfering with and disrupting the signal Vo which is being transmitted on the conductor placed near it. This phenomenon is most noticeable if the conductors are close to each other. inside a connector and the connector itself; Solutions have been used to address the phenomena of crosstalk between conductors.

_m0 however; The signals are transmitted at increasing bit rates; It may reach several gigabytes per second; The phenomenon of noise has become a part of and is no longer limited to the conductors that are located inside a conductor and the conductor itself. On cad day the phenomenon of crosstalk between conductors located in separate adjacent conductors is now being published. For example; A signal being transmitted at a high bit rate on a conductor produces an electromagnetic disturbance in the signals being transmitted on the adjacent conductor. This disturbance phenomenon between conductors is called "alien crosstalk" or "exogenous crosstalk". US Patent No. 0 proposes various solutions specifically to address the phenomenon of alien crosstalk. Some of the proposed solutions of this patent consist in particular of folding over the insulation contacts - 0 offset within the ey screen part The metal screen part can take different configurations. This diaphragm portion is placed outside the contact bearing material and is therefore considered particularly bulky. Furthermore; It shall have an outer metal sheath and an inner sheath made of insulating material to prevent any short circuit between wire length clearances within the conductor. Furthermore; A conductor is defined by US Patent Application No. 104470/706056 as comprising in particular a pilot part VO designed for routing and separating the wires located after the conducting material for the wires placed on the insulation-offset contacts. This pilot part makes it possible in particular to limit the Lad alien crosstalk related to external conductors. This connector has a defect in its pilot part, which also makes it possible to reduce extraneous noise; to be fixed to the outside of the body 0 connector; It shall be located at the level of the wires when the conductor is connected to the wires.

General description of the invention The invention aims to propose a conductor that makes it possible to mitigate the disadvantages of the previous field. This objective is achieved by means of a low-voltage connector designed for use in a telecommunications system and comprising: © - a body capable of being connected on its front part with a compatible conductor; support mounted inside the body comprising insulation-displacement contacts to each of which a wire in a cable is attached; The said contacts are placed in rows; - Metal screen part designed to limit the alien crosstalk | 0 with respect to adjacent conductors; - the body of the conductor includes a support material for the JS regulation - wire has multiple locations each designed to accommodate one end of the cable wire to be inserted into the insulation contact = displacement; The regulating carrier shall be attached to the body and positioned on the insulation-offset contacts such that at least one position corresponds to the insulation-offset contacts; Ve - ea bulkhead screen part is placed between the rows of insulation-offset contacts and clamped between the bearing material of the insulation-offset contacts and the bearing material of the cable-wire organization. according to the invention; Therefore, the barrier part does not take up a very large space, because it is Jing, the space between the rows of contacts; For example between two rows of contactors. The placement of the bulkhead portion between the rows of contacts makes it possible for the wire length clearances not to come into contact with them.

The length of the row of contacts, and the columns rest at the ends of the row, and each of them extends at a level that cuts

grade level; and on sufficient surface area to cover the contacts in row level.

according to other special features; in the middle of each transverse member; The screen part VO includes a central post standing parallel to two peripheral posts.

According to another special feature; for each row of contacts; The central post extends in one direction

parallel to the plane of the rows of contacts. It makes it possible to achieve a balance in the geometry of the part

septum around each pair of contacts; Thus improving electromagnetic symmetry.

According to another special feature; Two crossmembers are connected by at least one Ye strip running between two rows of contacts. according to a special feature al; Each row is formed from

=- 1 - The Je row of contacts is a part made of Ale material on which the offset-isolation contacts are installed. according to a special gal feature; for each row of contacts; The screen part transverse member extends over the insulating material portion of the row. this way; © Insulation-displacement contacts do not come into contact with the diaphragm portion. According to another special feature; The septum portion is symmetrical with respect to the plane equidistant from two crossmembers. According to another special feature, the bulkhead part is installed on the insertion axis of the conductor corresponding between the insulation-displacement contact bearing material and the cable-wire organizing bearing material. 0 Brief explanation of the drawings: Other characteristics and advantages are shown in the following detailed description with reference to a model to be included as an example and its representation in the attached drawings in which: - Figure No. 1 contains a first extended view of the connector of the invention; Figure No.?
