Description

Connector for performance telecommunications improved.

Background of the invention Invention Sector

The present invention relates, in a manner in general, to connectors for telecommunications, and in particular to male and female type telecommunications connectors They have improved performance characteristics.

Previous

Improvements in telecommunications systems have resulted in the ability to transmit voice and / or data signals through transmission lines at increasingly higher frequencies. Several industrial standards that specify multiple performance levels of paired wiring components have already been established. The first references, considered by many to be international references for commercially based telecommunications components and facilities, are ANSI / TIA / EIA-568-A (/ 568)
Commercial Building Telecommunications Cabling Standard and 150 / IEC 11801 (/ 11801), generic wiring for customer buildings. For example, Categories 3, 4 and 5 of cables and connection material are specified in both documents / 568 and / 11081, as well as in other national and regional standards. In these specifications, the transmission requirements for Category 3 components are specified up to 16 MHZ. Transmission requirements for Category 4 components are specified up to 20 MHZ. Transmission requirements for Category 5 components are specified up to 100 MHZ. New standards are being developed continuously and, at present, future standards are expected to require transmission requirements of at least 600 MHZ. To achieve these transmission frequencies, fully shielded paired cables will be necessary, in which each pair is individually wrapped in a sheet or screen. In addition, all pairs of conductors are wrapped together in a layer of sheet material or
screen.

The transmission requirements indicated above also specify close interference limits (NEXT). The telecommunication connectors are organized in pairs, typically constituted based on a male connector and a female connector. Since telecommunication connectors are reduced in size, adjacent pairs are placed in proximity to each other, creating interference between adjacent pairs. To meet the requirements of upcoming interference, a series of techniques have been used in this sector
cas.

U.S.A. 5,593,311 discloses a compact, shielded data connector, designed to reduce interference between connector contacts. Pairs of contacts within metal channels. When the connectors, the channels butt each other to enclose each of the pairs within a protection or metal screen. A Disadvantage of U.S.A. 5,593,311 is that metal channels are joined in a butt joint; a surface butt against adjacent surface without overlap. Since all the components include certain manufacturing tolerances, there is a potential for interstices between the elements of protection, thereby reducing the protection effect. Other disadvantage is that the cables in which the foil has been removed from protection can be exposed to each other on the back of the connector, which leads to interference. Therefore, there is a proven need in this sector to have connectors with Improved protection of conductor pairs.

In US Patent 5 593 311, the connector has an enclosure body that engages a similarly enclosed body to place the contacts in connection. The enveloping bodies are protected with two bodies joined in unions to
stop, top, maximum as a noun, top as an adverb.

U.S.A. 4 975 084 discloses a electrical connector system that has a dielectric, not a body wraparound conductor The contacts are intended for current, Earth and signals. The casing of dielectric material is couples with another body of dielectric material.

Detailed description of the invention

Figure 1 is a perspective view of a mounted male connector, which has been shown in general with the numeral (100), in accordance with the present invention. The connector male (100) comprises an upper cover (102), a lower cover (104) and a core (106). The top layer (102), the bottom cover (104) and the core (106) are all made of material driver to provide protection or shielding, as it has been will describe. These conductive components can be made to metal base, metallized plastic or any other material known driver. The core (106) supports contact holders insulators (for example, of plastic material) (108). Each of the contact holder (108) comprises two contacts (110) defining a pair of contacts. Expansion (112) provides elimination of tensions and is made of an adaptable plastic or rubber material. Also shown in Figure 1 is a cable (10) that enters the expansion (112). A retention element (114) is arranged in the upper cover (102) to connect the male connector (100) to the female connector (300), as will be described.

Figure 2 is a perspective view, with the disassembled parts, of the male connector (100). The element of retention (114) is constituted by a retention body (116) fixed to the top cover on the fulcrum (118). One tab (120) is arranged in the lower body (116) of retention for its coupling with a groove constituted in the female connector (300). This fixes the male connector (100) to the female connector (300). An important feature of the retention element (114) is a retention extension (122) that engages the retention body (116) to the top cover (102). The extension (122) of retention It is an arc element, adaptable, which flexes when applied pressure to the retention body (116). The male connectors of telecommunications suffer tensile stress frequently to through walls during installation. The prolongation of retention (122) reduces the probability that the male connector (100) is retained on other cables, wall corners, brackets, etc. The top cover (102) comprises a slot semicircular (129) and a bottom cover (104) includes a groove similar semicircular (129) that receives a circular flange (113) (Figure 7) in extension (112), as described below. Two retaining elements (128) of the upper cover are coupled with two recesses (130) of the lower cover to fix the upper cover (102) to the bottom cover (104).

The core (106) of the male connector comprises a first protection or flat screen (132) and a second screen flat (134) substantially perpendicular to the first screen flat (132). The core (106) of the male connector also comprises side walls (136). The top and bottom of each of the side walls (136) comprise a flange (140). The flanges (140) extend beyond the side wall (136) and overlap with an edge (142) of the top cover (102) and the cover lower (104). The flanges (140) have been shown endowed with general triangular cross section, but it will be understood that different geometries can be used without leaving the scope of the invention. The flanges (140) serve to locate the core (106) inside the upper and lower covers and overlap the edges of the top cover and bottom cover to provide better protection than in a butt joint. The second flat screen (134) also includes a flange (144) on the upper surface and lower. As shown in Figure 2, the center flange (144) is triangular, however, it will be understood that they can be use other geometries without leaving the scope of the invention. He center flange (144) is coupled with the channels (178) formed in the top cover (102) and bottom cover (104), as described later with reference to figures 3 and 4.

Two nerves (146) are constituted in the internal surface of each of the side walls (136) and are parallel to the first flat protection screen (132) and remain separated with respect to it. Similar nerves form in each of the surfaces of the second flat screen of protection (134). The contact support (108) has a flat base (148) resting on the first flat protection (132). Base (148) comprises two tabs (150) extending away from the base, and a stop (152) adjacent to the tabs (150). When he contact support is mounted on the support (106), the tab (150) is placed below the nerve (146) to maintain the contact support (108) with respect to the first flat screen (132). The contact support moves by sliding towards inside the core (106) until the stop (152) makes contact with the nerve end (146). In this position, a second tab (156) is arranged below a projection (154) constituted in the second flat screen (134). The support of contact (108) also includes a flange or lip (158) that extends substantially perpendicular to the flat base (148) and more beyond the edge of the first flat screen (132) to prevent the contact support (108) can slide out towards outside the core (106). Additional details of the contact support (108) and contacts (160) later, referring to figure 5. The inside of each side wall (136) and each side of the second flat screen (134) they also include a first facet (149) and a second facet (147), which are used to fix a terminal cap to the core (106) of the connector, as described below with reference to figures 6-10.

Figure 3 is a perspective view, with the disassembled parts, from the top cover (102). Top cover comprises a protective contact (164) that electrically connects the ground layer of the cable (10) to the core (106) of the male connector. The protective contact (164) is of conductive material and is preferably made from a metal. The contact of protection (164) has an arcuate part (166) constituted to adapt, in general, to the shape of the cable (10). The part arched (166) includes small blade areas (168) that drill the ground layer of the cable (10) and the envelope of the cable. This electrically and mechanically connects the contact of protection (164) to the cable (10). The protection contact (164) it comprises a plate (170) having two openings (172) constituted in it, intended to receive two stems (176) formed in the top cover (102). The friction coupling between stems (176) and openings (172) fix the protective contact (164) to the top cover (102). A tab (174) extends from the plate (170) and establishes contact with the core (106) of the connector male. A channel (178) is formed in the upper cover (102) for receive the central flange (144) of the core (106) of the connector male. This allows the central flange (144) to overlap by the channel side walls (178) and provide better protection than in a conventional butt joint. A slot (162) is arranged on the front face (103) of the top cover (102) to receive the second flat protection (134). The front face (103) of the connector male (102) also comprises two lowered areas (163) that receive extensions on the front face (317) of the female connector (300), as described below. The top cover (102) comprises recesses (139) of the side wall to receive rear extensions (137) of the core (106) of the male connector (figure 6) to create an overlap between the back of the side wall (328) of the core of the male connector and the top cover of said male connector. The top cover (102) also comprises side walls (105) that have extensions (143) of the wall upper side that fit with the recesses (343) of the wall side of the female connector (figure 4) to create an overlap between the side walls (105) of the top cover (102) of the connector male and the side walls (107) of the lower cover (104) of the male connector.

Figure 4 is a perspective view, with the disassembled parts, from the bottom cover (104). Bottom cover (104) is similar to the top cover (102) due to the fact that both use the protective contact (164) in the same way. Cover lower (104) also comprises the channel (178) to receive the central flange (144) on the second flat protection (134). Such As indicated above, this allows the flange center (144) is overlapped by the sides of the channel (178) and provide better protection than a conventional butt joint. The groove (162) is arranged on the front face (103) of the lid bottom (104) to receive the second flat protection (134). The lower cover (104) comprises side walls (107) that have recesses (139) on the side walls, similar to those on the cover upper (102), to receive subsequent extensions (137) of the side wall (136). In addition, the lower cover (104) comprises second recesses (343) of the side wall to receive the extensions (143) of the side wall on the top cover (102). The front face (103) of the lower cover (104) is similar to that of the upper cover (102) and includes recesses (163) to receive the extensions on the front face (317) of the female connector (300). The front face (103) of the lower cover (104) also comprises a lip (165), interrupted by recesses (163), which overlaps with the outer surface of the bottom wall (332) of the core (306) of the female connector.

Figure 5 is a perspective view, with the disassembled parts, of a support (108) of contacts. The support of contacts comprises two channels (186), each of which receives a contact (160). Each of the contacts (160) has a body (180) generally flat, a contact end (182) and a terminal end (183). The terminal end comprises a contact (184) insulation displacement that cuts the insulation of the individual cables of the cable (10) to make contact electric with the conductor as is known in this technique. The installation of the conductors in the contact (184) of insulation displacement is described with reference to Figures 8-10. Each of the contacts of insulation displacement forms a certain angle with respect to the longitudinal axis of the body (180) according to an angle of 45 degrees. As shown in Figure 1, the male connector (100) It comprises four contact supports (108), each of which It has a pair of contacts (160) with a total of eight contacts.

Figure 6 is a perspective view, with the disassembled parts, of the male connector (100) comprising the terminal caps (186). A terminal cap (186) is left arranged for each pair of contacts (160). As it is known in this technique, a terminal hood forces drivers to a insulation displacement contact to cut the insulation and electrically connect the conductor and the contact of insulation displacement. The terminal cap (186) comprises a first lip (188) and a second lip (190) that embrace the facets (149) and (147) of the core (106) of the male connector. The first lip (188) and the second lip (190) have a surface chamfered, and said first and second facets (149) and (147) similarly include a chamfered surface for facilitate the assembly of the terminal cap (186), as given to Know later. Each of the terminal caps (186) It also includes two contact openings (192) to receive the isolation displacement contacts (184) and a pair of openings (194) for cables to receive cable conductors (10) The openings (194) for the conductors are aligned with the contacts (184) of insulation displacement in the core (106) of the male connector. The male connector of Figure 6 has been shown in the situation as received by the client. The end caps (186) are arranged in the core (106) of the male connector and are retained in a first position. The first lip (188) rests on the first facet (149) to retain the terminal cap (186) in a first position and a second lip (190) is arranged below the first facet (149) to prevent the terminal cap (186) from being disassembled so inadvertent of the core (106) of the male connector.

Figure 7 is another perspective view, with the disassembled parts, of the male connector (100). As it has been shown in figure 7, each of the end caps (186) is in the first position by virtue of the first lip (188) and the second lip (190) embrace the first facet (149). The expansion (112) comprises a cylindrical lip (113) that engages with the groove (129) formed in the upper cover (102) and in the cover lower (104). The slots (115) can be constituted through of the expansion (122) and perpendicular to the lip (113) to allow that said lip (113) expands during the installation of the expansion (112), reducing the force needed to install and remove the expansion (112).

The installation of the conductors in the connector male (100) will be described below with reference to the Figures 8-12. As shown in the figure 8, the cable (10) comprises eight conductors (198). Each pair of conductors (198) is fitted by a screen (200) of a pair of drivers. The earth layer (196) is also housed within the cable (10) and is removed on the outer envelope of said cable (10) The conductors (198) are inserted into the openings (194) for drivers of the end caps (186). As it has been described above, each of the openings (194) for conductors is aligned with a displacement contact (184) of insulation and, therefore, each of the conductors (198) is disposed above the displacement contact (184) of isolation. It will be understood that the expansion (112) is located over the cable (10) before inserting the conductors (198) into the terminal caps (186). Figure 9 shows the conductors (198) arranged in the conductor openings (194). Once the conductors (198) are positioned in the terminal caps (186), a force is applied to each terminal cap (186) towards the core (106) of the male connector, in the direction shown by the arrows in figure 9. A tool can be used for a single hand to apply force to the four end caps (186) at the same time to get an easy installation.

Figure 10 shows the end caps (186) in a second position. The first lip (188) and the second lip (190) then embrace the second facet (147) to support the terminal cap (186) in the second position. In this situation, cables (198) located in cable openings (194) are directed on the displacement contacts (184) of isolation. As is known in the art, the contacts of isolation offset (184) divide the insulation into each cable (198), thus allowing electrical contact between the wires (198) and the contacts (160). An important aspect of the invention, shown in figure 10, is the use of a zone buffer (206). The length of the first flat screen (132) and the second flat screen (134) is such that the part of the first flat screen (132) and the second flat screen extend further beyond the back of each terminal cap (186) to establish a buffer zone (206). Each pair of cables rests on the buffer zone (206). The buffer zone (206) is important because, during installation, the screen (200) of the cable pair is eliminated so that individual drivers can be inserted into the conductor openings (194). Even assuming the installer has removed the exact length recommended of the screen (200) of the pair of conductors, a reduced amount of exposed driver will generate interference between adjacent pairs at frequencies greater than 600 MHZ. In non-ideal installations, the installer will remove an amount excessive display (200) of the pair of conductors. This way, the buffer zone (206) reduces the interference in ideal and non-ideal facilities, and increases the performance of the connector The buffer zone must have a length, measured from the back of the terminal cap (186), superior to the exposed conductor length (198) (torque display drivers removed) in the worst case of installation.

The next stage in the installation process is the placement of the top cover (102) and the bottom cover (104) on the core (106) of the male connector, as it has been shown in figure 11. The top cover (102) and the bottom cover (104) comprises, each of them, projections (202) that are they engage in similarly shaped recesses (204) on the male connector (106) to fix the top cover (102) and the cover lower (104) to the core of the male connector (106). In addition, the retaining elements (128) of the upper cover are coupled with the openings (130) of the lower cover to fix the upper cover (102) to the bottom cover (104). Blade elements (168) of protective contacts (164) penetrate the ground layer (196) and the cable sheath to connect mechanically and electrical protection connectors (164) to the cable (10). The phase final in the assembly of the male connector is the fixing of the expansion (112) to the connector. As shown in the figure 12, the expansion (112) is retained under pressure on the covers upper and lower. The lip (113) of the inner surface of the expansion (112) is coupled with the groove (129) formed in the lid upper (102) and in the lower cover (104).

Figure 12A is a perspective view of the male connector in an alternative embodiment. As you can appreciate in figure 12A, the expansion (112) comprises two channels L-shaped (197) receiving the stem (124) formed in the lid upper (102) and the stem (126) formed in the lower cover (104) (figure 12B). The expansion (112) is fixed to the top cover (102) and lower cover (104) when placing the stems (124) and (126) in the channels (197) and rotating the expansion (112).

Figure 13 is a perspective view of a Female connector (300) to be used with the male connector (100). He Female connector (300) comprises an upper stage (302), a stage bottom (304) and the core (306). The top cover (302), the cover bottom (304) and core (306) are all conductors, providing protection as described above. These conductive components can be made in a metal, in Metallic plastic or any other known conductive material. The core (306) supports the insulating contact holders (308). Each of the contact supports comprises contacts (310). I also know has provided an optional door (311) to prevent the entry of contamination (for example, dust) in the female connector (300).

The upper cover (302) comprises a pair of elastic arms (312) having grooves (314) constituted in the same. The slots (314) receive the edge of such a face plate as will be described later, with reference to figure 23. Other slot (315) is constituted at the bottom of the core (306) of the Female connector to receive another edge of the faceplate. The slots (314) and (315) are in a plane that is arranged at an oblique angle to the front face (317) of the connector female (300). Once mounted on a faceplate, it directs the female connector towards the floor and provides a design of gravity feed. Gravity feeding reduces the angle of inclination of the cable connected to the male connector (100) and reduces the likelihood of the cable bending beyond the radius minimum curvature, causing signal degradation or loss of the same. Alternatively, the slots (314) and (315) can be find in a plane parallel to the front face (317) of the connector female (300).

Figure 15 is a cross-sectional view. of the core (306) of the female connector along the line (15-15) of Figure 14. As shown in Figure 15, the first flat protection (336) and the second flat protection (338) comprise protection extensions (342 ') that overlap with the ends (133) and (135) of the first flat protection (132) and the second flat protection (134) of the male connector (100). The extensions (342 ') of protection have a thickness that is less than the thickness of the first flat protection (336) or the second flat protection (338). Some hooks (344) in the upper part and the lower part of the core (306) of the Female connector are coupled with the openings (346) of the lid upper (302) and lower cover (304).

Figure 16 is a perspective view, with the disassembled parts, from the top cover (302). Top cover (302) comprises the protective contact (164) described previously with reference to the male connector (100). Cover upper (302) further comprises projections (348) to support the protection contact (164) due to the different geometry of the female connector (300). The top cover (302) comprises the recesses (303) along an upper wall (301) and a side wall (307) to receive the extensions (327) in the core (306) of the female connector (figure 19). The side walls (307) comprise projections (309) that are received in the recesses (313) of the cover lower (304). A channel (178) is arranged in the upper wall (301) to receive the flange (337) in the second flat protection (336).

Figure 17 is a perspective view, with the disassembled parts, of the lower cover (304). Bottom cover (304) comprises the protective contact (164) described previously with reference to the male connector (100). Cover bottom (304) further comprises the projections (348) to support the protection contact (164) due to the different geometry of the female connector (300). The recesses (303) are constituted in the bottom wall (323) of the bottom cover and on the side wall (321), and receive extensions (327) (figure 19) of the walls sides (328) of the core (306) of the female connector. The walls sides (321) further comprise recesses (313) to receive the projections (309) of the upper cover (302). One channel (178) remains arranged on the bottom wall (323) to receive the flange (337) of the second flat protection (336).

Figure 18 is a perspective view, with the disassembled parts of the contact support (308). The support of contacts is insulating and comprises an enveloping body (352) of general rectangular shape, which has a pair of grooves (354) formed in it to receive contacts (350). Slots (354) are formed through a body surface envelope (352), so that a part of the contact (350) is extends beyond the surface of the enveloping body (352), such as shown in figure 14. The contact (350) comprises a isolation displacement contact (356) at one end for drill the insulation of a conductor and to make contact electric. The insulation displacement contact (356) forms a certain angle with respect to the longitudinal axis of the contact (350) according to an angle of 45 degrees. The contact (350) also includes a spring part (358) that extends beyond the surface of the casing body (352), as shown in Figure 14. When the male connector and the female connector are coupled, the contacts (110) of the male connector (100) make contact with the spring part (358) of the contacts (350) in the female connector (300) and flex the spring part (358) towards the body envelope (352). The spring part (358) is forced towards the contact (110) and ensures good electrical contact between the connector male (100) and female connector (300). The enveloping body (352) comprises the step (360) that establishes contact with the nerve (340) in the core (306) of the female connector to secure the contact support (308) to the core (306) of the female connector.

Figure 19 is a perspective view, with the disassembled parts of the female connector (300). The hoods terminals (186) are used to install conductors in the insulation displacement contacts (356). The hoods terminals (186) are identical to those described above with reference to the male connector (100). The female connector (300) it comprises first facets (149) and second facets (147) formed on the side walls (328) and second flat protection (336). Such as described above with reference to the male connector (100), the terminal cap (186) is supported in a first position by the first lip (188) and the second lip (190) that they embrace the first facet (149). Cable openings (194) receive conductors (198) and are aligned with contacts of insulation displacement (356). As described previously, the side walls (328) comprise extensions (327) on the upper, lower and back sides thereof, for coupling recesses (303) on the top cover (302) of the connector female and the lower cover (304) of the female connector.

The installation of the conductors in the female driver (300) will be described below by doing reference to figures 20-22. As shown in figure 20, the cable (10) comprises eight conductors (198). Each pair of conductors (198) is housed by a torque protection of conductors (200). The earth layer (196) is also housed inside the cable (10) and is removed on the outer envelope of the cable (10). The conductors (198) are inserted into openings for conductors (194) in terminal caps (186). As it has been described above, each driver opening (194) is aligned with an isolation displacement contact (356) and, therefore, each conductor (198) is placed above a insulation displacement contact (356).

Figure 21 shows the conductors (198) positioned in the cable openings (194). Once the wires (198) are placed in the end caps (186), apply force to each termination cap (186) towards the core (306) of the female connector in the direction shown by the arrows of Figure 21. As explained above with reference to the male connector (100), a single tool can apply force to the four terminal caps at once. The Figure 21 shows the end caps (186) in a second position. The first lip (188) and the second lip (190) embrace then a second facet (147) to retain the hood terminal (186) in the second position. In this situation, the conductors (198) arranged in the openings (194) for them they are introduced in the contacts (356) of displacement of the isolation. As is known in this technique, contacts (356) Insulation offset cut insulation of each conductor (198), thus making the electrical contact between the conductors (198) and the contacts (350). The connector female (300) also comprises a buffer zone (206) similar to the one described above with reference to male connector (100). A part of the first flat protection (336) and the second flat protection (338) extend beyond the terminal caps (186) to provide the zone of damping (206) that has the disadvantages above described with reference to the male terminal (100).

The next stage in the installation process is the placement of the top cover (302) and the bottom cover (304) on the core (306) of the female terminal, as it has been shown in figure 22. The opening (346) in both the lid upper (302) as in the lower cover (304) is placed on a corresponding hook (344). The top cover (302) and the cover lower (304) are turned, then towards each other, and the retaining elements (128) of the upper cover are coupled with the openings (130) of the lower cover to fix the upper cover (302) to the bottom cover (304). Cutting edges (168) of the protective contacts (164) penetrate the ground layer (196) and in the cable sheath (10) to connect electrically and mechanical protection contacts (164) to the cable (10).

Figure 23 is a perspective view of the Female connector (300) mounted on the front plate (400). As it shown in figure 23, the opening of the female connector (300) It forms an angle to the front plate. This angle is established by the groove (314) on the top cover (302) of the female connector and slot (315) in the core (306) of the connector female arranged in a plane, which forms an oblique angle with respect to to the face (317) of the female connector. As noted previously, this creates a feed orientation by severity in which the cable connected to a male connector coupled with the female connector (300) it forms an angle towards the ground, therefore reducing the curvature of the cable. This reduces the probability that the cable will bend below a radius of minimum curvature The identifier (324) also serves as a closure fixing the female connector (300) on the front plate (400). For install the female connector (300) on the front face (400), the elastic arms (312) are flexed until both slots (314) and (315) are aligned with the edge of the plate opening frontal. In this position, the arms (312) return to their position original. When the identifier (324) is arranged in the recess (318) and recess (322), this prevents the arms (312) from flexing towards the core (306) of the female connector and therefore blocks the Female connector (300) in position on the front plate (400). The Figure 24 is a perspective view of the male connector (100) coupled with the female connector (300). The lip (120) is coupled with the recess (326) to fix the male connector (100) to the connector female (300). In an alternative embodiment, the female connector (300) can be mounted in a flat configuration, in which the female connector face is parallel to the front plate (400), such as described above.

The present invention provides a male connector and female connector for telecommunications, improved, in which a pair of contacts is individually protected. They don't join two separate protection elements with butt joint, but all significant connections between separate protection elements (not integral) comprise a certain form of overlap. The figures 25-32 show the protection joints that are overlap. Figure 25 is a side view of the male connector (100). Figure 26 is a cross section according to the cutting line (26-26) of Figure 25 and shows the overlap between several protection elements of the male connector. Figure 27 is a cross section according to the cutting line (27-27) of Figure 25. The female connector (300) is similar to the male connector (100) due to the fact that the top cover (302) and the bottom cover (304) comprise channels (178) to receive the flanges (337) of a second flat protection (336). Cover upper (302) and lower cover (304) comprise recesses (303) to receive the extensions (327) of the side walls (326) of the female connector core. The extensions (309) of the lid upper (302) of the female connector are housed in the recesses (313) of the lower cover (304) of the female connector itself.

Figure 28 is a side view of the connector male (100) coupled to the female connector (300), and the figures 29-32 are cross-sectional views according to the Figure 28. Figure 29 shows the overlap between elements of protection in the core of the female connector and the core of the connector male. As shown in Figure 29, the second element of flat protection comprises a displaced nerve (207) along its edge that overlaps with its extension of protection (342). He displaced nerve (207) also provides a cotter function, so that the male connector can only be installed in the Female connector (300) in a single orientation. Similarly, the first flat protector (132) comprises a displaced nerve (209) in its edge for channel coupling (338), which provides also a cotter effect. Figure 30 shows the overlap between the core of the female connector, the top cover of the female connector and the lower cover of the female connector itself. Figure 31 is a cross-sectional view of the connection between the male connector and the female connector, showing the way in which the upper wall (319) of the female connector and the side walls (328) of the own Female connector overlap with the front face (103) of the connector male (100) Figure 32 is a sectional view along the line of section (32-32) of figure 28, showing the lip (165) of the bottom cover that extends below the wall (332) bottom of the core of the female connector. According to that, each of the contact brackets is enclosed in a quadrant in which all protection joints have a certain overlap and the magnitude of peer protection is increased by comparison with the protection provision using unions to stop, top, maximum as a noun, top as an adverb.

He Contact support (508) has a flat base (542) that rests over the flat protection (532). The base (542) comprises two tabs (544) extending away from the base (542), of so that the flange (544) has an inclined part (545) in a end and a stop (547) at the opposite end. When the support of contacts (508) is installed in the core (506), the tab (544) is placed below the nerve (552) to maintain the support of contacts (508) with flat protection (532). The support of contacts (508) is coupled by sliding inside the core (506) until the stop (547) makes contact with the end of the nerve (552). In this position, a fin (546) is arranged so which, when the contact support (508) slides inside the core (506), the fin (546) makes contact with a shape recess similar in the flat protection (532) and positions the support of contacts (508) in the core (506). The contact support (508) also includes a lip (603) (shown in Figure 36B) that is extends substantially perpendicular to the flat base (542) and beyond the edge of the flat protection (532) to prevent the contact support (508) exit the core (506).

The recesses (550) are arranged in the flat protection (532) to receive the ribs (736) from the walls side of the female connector (700) and provide overlap between side walls of the female connector (700) and flat protection (532). The interior of each side wall (534) also comprises a first facet (556) and a second facet (554) that are used for fixing a terminal cap (558) as described further forward, referring to the figures 36-39.

The arched area (562) it comprises cutting edges (564) that cut the earth layer of the cable (514) and the cable sheath. This connects electrical and mechanically the protective contact (560) to the cable (514). When the retaining element (516) is coupled with the top cover (502), the arcuate part (562) engages below the narrowing (573) of the upper cover (502). Once the assembly, the arched part (560) is arranged inside of the male connector (500) and the rest of the retention element (516) It is arranged outside the male connector (500). The element of retention (516) comprises a first receiving opening (566) and a second receiving opening (568) formed within the body (518) of the retention element A first opening (566) is intended for receive a pin (570) formed in the upper cover (502) and a second opening (568) is intended to receive a rod (572) formed in the top cover (502). The stem (572) comprises a narrowing (574) and a head (576). The first opening receiver (566) has a slot (567) and a second opening receiver (568) has a slot (529) to establish contact with the narrowing (571) of the tongue (570) and the narrowing (574) of the stem (572), respectively. The retention element (516) is coupled with the top cover (502) by alignment of the first receiving opening (566) with the chamfered surface of the tab (570) and aligning the second receiving opening (568) with the head (576) of the stem (572), and moving by then slide the retaining element (516) in the direction towards the stem (572), so that the narrowing (571) of the tongue (570) slidably engages with the groove (567) and the narrowing (574) of the rod (572) is coupled Sliding with the groove (569). The top cover (502) it also comprises an outgoing button (578) arranged below the retention element (516). The projections (582) are coupled with similarly recesses (584) on the side walls (534). He protruding button (578) is constituted on the top cover (502) below the part (518) of the body to limit the displacement of the retention element (516) towards the lid upper (502). The top cover (502) comprises side recesses (583) to receive the side walls (534) and to engage with the same, so that the recesses (583) comprise a flange which has an inclined zone (588) (figure 36A) and a receiving zone (590) (Figure 36A), so that the side walls (534) are received on the flange part and the inclined part of said flange causes the side walls (534) to run over the support part, thereby coupling the two elements between yes with overlap.

Figure 36A is a perspective view of the bottom cover (504). The bottom cover (504) comprises a recess (585) similar to the recess (583) on the top cover (506), so that the recess (585) comprises a facet (586), an inclined area (588) of said facet and a support zone or receiving zone (590) intended to receive the side walls (534) of the core (506). The side walls (534) are received in the facet (586) and the side walls (534) move over the inclined area (588) of said facet towards the support part (590). This allows the side walls (534) overlap by the recess (584) of the bottom cover (504). Said lower cover (504) also comprises a projection (582) for similar coupling with a shape recess circular (584) of each of the side walls (534). Cover Bottom comprises side walls (596) that have recesses (598) of the side wall with a step part, similar to that of the top cover (506), to receive the side walls (534), thus allowing the overlap of said side walls (534) and the bottom cover (504) when the side walls (534) They make a stop with the stepped part. The bottom cover (504) can comprising a lip (165) as described above with reference to the male connector (100) for the overlap with the lower part of the female connector (700).

Figure 36B is a perspective view, with the disassembled parts of the male connector (500) comprising the end caps (558). A terminal cap is provided for Each pair of contacts. As is known in this technique, the terminal cap leads the conductors over the contact of insulation offset to cut the insulation and connect electrically the conductor and the displacement contact of the isolation. The end cap (558) comprises a first lip (600) and a second lip (602) that embrace the facets (554) and (556) of the core (506) of the male connector. The first lip (600) and the second lip (602) have a chamfered surface, and a first facet (556) and a second facet (554) similarly have a chamfered surface for easy mounting of the hood terminal (558), as indicated below. Each of the end caps (558) also comprises an opening of contact (604) to receive the displacement contacts (184) of the insulation (shown in figure 5) as well as a pair of openings (606) for conductors, intended to receive cable conductors (514). The openings (606) of the cable are aligned with the insulation displacement contacts (184) (figure 5). The male connector of Figure 36B has been shown in the situation in which it is received by the client. The hoods terminals (558) are arranged in the core (506) of the terminal male and held in a first position. The first lip (600) rest on the first facet (556) to retain the hood terminal (558) in a first position, and a second lip (602) is arranged below the first facet (556) to prevent that the terminal cap (558) can be disassembled inadvertent core (504) of the male connector.

Figure 37 is another perspective view, with the disassembled parts, of the male connector (500). As it has been shown in figure 37, each of the end caps (558) is in the first position by action of the first lip (600) and the second lip (602) that embrace the first facet (556). The expansion (512) comprises a cylindrical lip (513) that engages with the groove (526) of the upper cover (502) and the lower cover (504).

The installation of the wires in the terminal male (500) will be described below with reference to the Figures 38-41. As shown in the figure 38, the cable (514) comprises four conductors (608). Each pair of conductors (608) is embedded within a protector (610) for a pair of drivers The earth layer (612) is also housed inside the cable (514) and is removed on the outer envelope of the cable (614). The cables (608) are inserted in the openings (606) for the cables in the end caps (558). As it described above, each of the openings (606) for wires is aligned with an insulation contact (184) and, therefore therefore, each wire is disposed above a contact (184) of insulation displacement (shown in figure 5). Be you will understand that the expansion (512) is located on the cable (514) before inserting the wires into the end caps (558). A Once the wires are positioned in the end caps (558), force is applied to each of the end caps toward the core (506) of the male connector in the direction that has been shown by the arrows in figure 38. A single tool manual can be used to apply force to the two caps terminals (558) at the same time, for easy assembly.

Figure 39 shows the end caps (558) in a second position. The first lip (600) and the second lip (602) then embrace the second facet (554) to retain the terminal cap (558) in the second position. In this situation, the conductors (608) arranged in the openings (606) for the they are brought to the contacts (184) of displacement of the isolation. As is known in this technique, contacts (184) insulation displacement cut the insulation in each of the conductors (608), thus getting contact electrical between the conductors (608) and the contacts (160). A important aspect of the invention, as shown in the Figure 39, is the use of a buffer zone (614). The flat protection length (532) extends beyond the back of each terminal cap (558) to establish a buffer zone (614). Each pair of drivers rests on the buffer zone (614). The buffer zone (614) is important because, during installation, the protector (610) of a pair of conductors is removed so that conductors can be inserted individual openings (606) for the cables. Assuming even that the installer has removed the exact recommended length of the protection (610) of the cable pair, a small amount of Exposed cable will create interference between pairs adjacent to frequencies above 600 MHZ. In facilities that are not Ideally, the installer will remove an excess of the protector (610) from the pair of wires Therefore, the buffer zone (614) reduces interference in installations or less ideal and increases the connector performance The buffer zone (614) must have one length, measured from the back of the hood terminal (558), greater than the length of the exposed wire (608) (cable pair protector removed) in an installation corresponding to the most unfavorable case.

The next stage in the installation process is the placement of the top cover (502) and the bottom cover (504) on the core (506) of the male connector, as it has been shown in figure 40. The top cover (502) and the bottom cover (504) comprise, each of them, projections (582) that are they engage in similarly recesses (584) of the core (506) of the male connector to secure the top cover (502) and the cover upper (504) in the core (506) of the male connector. In addition, the retaining elements (528) of the top cover are coupled with the openings (530) of the lower cover to secure the upper cover (502) to the bottom cover (504). The retention element (516) is fixed to the top cover (502) by means of the alignment tab (570) with a first receiving opening (566) and engaging in sliding with the narrowing (571) with the groove (577) in the that the slot (567) is integrally connected with the first receiving opening (566). During the coupling of the element of retention (516) to the top cover (502), the stem (572) is received in the second receiving opening (568), so that the Narrowing (574) of the stem (572) is sliding coupled inside the slot (569). The retention element (516) has been shown in figure 40 in the first position, in which the body of retention (518) stops against the part (576) of the head of the rod (572) when the retention element (516) is made in an elastic material and due to the interposition of the narrowing (571) with the slot (567). The protective contact (560) of the retention element (516) is arranged below the narrowing (616) of the upper cover (502), so that the Protective contact (560) is coupled with the cable (514). Nail edges (564) of the protective contact (560) penetrate the layer ground (612) and the cable sheath to connect so Mechanical and electrical protection contact (560) to the cable (514). The final stage in the assembly of the male connector is the fixing of the expansion (512) to the male connector (500). As shown in figure 41, the expansion (512) is retained under pressure on the top and bottom caps. The lip (513) of the inner surface of the expansion (512) is coupled with the groove (526) formed in the upper cover (502) and in the lower cover (504).

Figure 42 is a perspective view of a female connector mounted from a first alternative embodiment, shown in general with the numeral (700), so that the Female connector (700) is intended for use with the male connector (500). The female connector (700) is similar to female connector (300) except the second flat protection (336) It is replaced by vertical protection (732). Female connector (700) comprises an upper cover (702), a lower cover (704) and a core (706). The upper cover (702), the lower cover (704) and the core (706) are, all of them, conductors to provide protection as described. These conductive components they can be made of metal, metallic plastics or Any other known conductive material. The core (706) supports the insulating contact holders (708). Each of the contact holders includes contacts (710). An optional door (711) is arranged also to prevent the entry of contaminants (for example, powder), in the female connector (700).

The upper cover (702) comprises a pair of elastic arms (712) equipped with grooves (714) formed in its inside. The slots (714) receive the edge of a faceplate, as described with reference to figure 23. Other slot (715) is constituted at the bottom of the core (706) of the Female connector to receive another edge of the faceplate. The slots (714) and (715) are in a plane that is forming an oblique angle with respect to the front face (717) of the female connector (700). Once mounted on a front face, this directs the female connector to the ground and provides a design of gravity feed. Gravity feeding reduces the bend angle of the cable connected to the male connector (500), and reduces the probability that the cable can bend beyond the minimum radius of curvature, causing degradation or loss of signal. Alternatively, the slots (714) and (715) can be find in a plane parallel to the front face (717) of the connector female (700). An element (716) connects the ends of the arms elastic (714) and includes a recess (718) on a front face of the same. The recess (718) receives an edge of a badge identifier (724) (shown in figure 43). The badge of identification (724) rests on the support surface (720) and establishes contact with a recess (722). Both the surface of support (720) as the recess (722) are constituted on the core (706) of the female connector.

The upper cover (702) and the lower cover (704) of Figure 42 are described below with reference to the Figures 14-16 The core of the female connector of the Figure 42 has a general rectangular shape and comprises walls lateral (726), upper wall (728) and lower wall (730). A notable difference between the female connector (300) of Figure 13 and The female connector (700) of Figure 42 is a flat screen vertical (732) that extends to the entire length of the core of output (706), thus dividing the core (706) in a half on the left and one half on the right to provide a Improved performance by isolation of contact pairs. Every one of the halves is designed to receive a male connector (500) of two pairs represented in Figure 33. The walls lateral (726) and vertical protection (732) comprise ribs (736) to fit into the recesses (550) of the flat protection (532) to create overlapping protection elements.

An important feature of the connector female (700) is the formation of the opening (740) in the core (706) of the female connector. The opening (740) is designed to receive the extension (524) of retention of the male connector (500) and serves to block the male connector (500) to the female connector (700). The retention extension (524) is guided inside the opening (740) and, as shown in Figure 47, the lower face of the upper wall (728) of the core (706) of the female connector comprises a lip (1200) (figure 59) to fit the opening (568) in the extension (524) of retention. When the extension is inserted or retention extension (524) within the opening (740), a chamfered surface (1202) of said lip allows the retention extension (524) engages with sliding with the core (706) of the female connector when blocking the extension of retention (524) with the part (1204) of the lip step (1200). To release the male connector (500), the retaining element (516) is pressed towards the top cover (502) to undock the opening (568) of the lip (1200). In an arrangement similar to female connector (300) of Figure 13, the top cover (702), the lower cover (704) and the core (706) of the female connector (700) they have overlapping joints to better insulate and protect the pairs of contacts so that you can get an improvement of performance.

Figure 43 is a perspective view of two male connectors (500) according to figure 33, coupled with the connector female (700). In figure 43, the female connector (700) is mounted on a faceplate (800). The opening of the female connector (700) It forms a certain angle with respect to the faceplate. This angle is determined by the groove (714) of the top cover (702) of the female connector and slot (715) of the female connector core (706), which are arranged in a plane forming an oblique angle with respect to the face (717) of the female connector. As it has been indicated above, this creates a feeding orientation by gravity, in which the cable connected to a male connector coupled with the female connector (700) forms an angle towards the ground, thus reducing the curvature of the cable. This reduces the probability that the cable is bent below the radius of minimum curvature Identification badge (724) serves also as a locking element to fix the female connector (700) on the front plate (800). To mount the female connector (700) on the front plate (800), the elastic arms (712) are flexed until both the slot (714) and the slot (715) are aligned with the edge of the front plate opening. At this time, the arms (712) return to their original position. When the badge of identification (724) is arranged in the recess (718) and in the recess (722), this prevents the arms (712) can flex towards the core (706) of the female connector, thereby blocking the female connector (700) in position on the front plate (800). In this embodiment, the use of two male connectors (500) of two pairs in the female connector (700) occupies the same space as the use of a four-pair male connector (100) in the female connector (300). Advantageously, the user can select the insert one of the two male connectors (500) in the female connector (700), without worrying about whether the Installation will require additional space.
