Description

Technical Field

[0001] The utility model relates to the technical field of network connection equipment, and in particular to a shielded network module and a network connector. Background Art

[0002] In the wiring system, the communication between communication devices such as network cards, hubs or switches and computers needs to be connected through network connectors, such as standard RJ45 connectors; existing network connectors are mainly composed of network connectors (also called crystal heads) and modules (also called sockets). As for modules, when they are applied to shielded cable systems, since the entire link must be shielded, including cables and connectors, a shielded network module is required to connect communication equipment. The commonly used shielded network modules in the existing network integrated wiring system are mainly Category 5, Category 6, Category 6e and Category 7 shielded network modules.

[0003] With the development of network wiring technology, network modules are usually installed on the wall in the form of a junction box. Specifically, the network module is housed in a junction box, but its socket end is exposed on the surface of the junction box. The network connector on the network cable of the terminal device (such as a PC) is directly inserted into the socket of the network module to achieve network connection; for example, the existing RJ45 network module is mainly connected to the wall through a standard 86 panel box. However, for the shielded network module, since it needs to fix the shielding wire on the cable, the shielding wire needs to be led out from the module body to the outside of the metal shell and wrapped around the outer wall of the metal shell to achieve grounding. For example, in the existing Category 6 or Category 6A shielded network module, the rear end needs to extend two semi-tubular bodies that cover each other. While the two cover to form a network cable card hole, the cable shielding wire can also be wrapped around the two semi-tubular bodies to achieve shielding wire grounding. However. The setting of the end semi-tubular body greatly increases the length of the shielded network module. When it is installed in a standard 86 panel box, the longitudinal remaining space of the box body is small and it is difficult to wire, or even impossible to wire, thereby greatly limiting the application of the shielded network module.

[0006] According to one embodiment of the utility model, a wiring portion extending to the rear end wall of the metal shell is formed at the rear end of the cable management seat, and a through hole or a wire clamping groove extending to its end is formed on the peripheral wall of the wiring portion.

[0009] According to an embodiment of the utility model, the outer peripheral wall of the wire management seat where the wiring channel is located is rounded to increase the space of the shielding cavity.

[0010] According to one embodiment of the utility model, the metal shell includes a shell body and a rear end cover detachably covered on the shell body, the shell body covers the module body and the cable management seat, a wire passing hole is formed on the rear end cover and the outer surface of the rear end cover is roughly flat, and a shielding cavity is formed between the inner wall of the rear end cover, the inner wall of the shell body and the rear end outer wall of the cable management seat.

[0011] According to one embodiment of the utility model, the metal shell includes a shell body and two metal fasteners relatively hinged to the rear end of the shell body, the shell body covers the module body, the two metal fasteners are detachably engaged to form a cable management seat accommodating cavity and the rear ends of the two are surrounded by a rear end wall having a wire passing hole; in the engaged state, a shielding cavity is formed between the peripheral walls of the two metal fasteners, the rear end wall surrounded by them and the rear end outer peripheral wall of the cable management seat.

[0025] In order to achieve the grounding requirement of the shielded wire, the existing shielded network module needs to form a semi-tubular body at the rear end of the metal shell to achieve the grounding of the shielded wire and the metal shell. This grounding shielding method greatly increases the length of the shielded network module. When it is installed based on the existing standard 86 panel box, it occupies more panel box space in the length direction, which brings great difficulties to the panel box wiring, and even makes it difficult to match the existing standard panel box.

[0026] In view of this, if Figures 1 to 6 As shown, the shielded network module provided in this embodiment includes a metal shell 1, a module body 2 and a cable management seat 3. The metal shell 1 is a hollow structure and its rear end wall 111 is roughly flat, and the rear end 11 of the metal shell is an openable structure. The module body 2 is accommodated in the metal shell 1 and extends to the front end 12 of the metal shell, and the front end of the module body 2 is formed with a socket 21 for detachable engagement of the network connector. The cable management seat 3 is accommodated in the metal shell 1 and plugged into the rear end of the module body 2. The plug-in front end of the cable management seat 3 is formed with a plurality of engagement grooves 301 for engaging the cable cores, and the rear end of the cable management seat 3 is formed with a wiring channel 302 connected to the inner cavity of the metal shell 1, and a shielding cavity 303 is formed between the outer peripheral wall of the rear end of the cable management seat 3 and the metal shell 1. The shielding wire on the cable fixed on the cable management seat 3 extends from the cable management seat 3 into the metal shell 1 through the wiring channel 302 and is accommodated in the shielding cavity 303 and electrically connected to the metal shell 1.

[0027] Based on the arrangement of the wiring channel 302 on the cable management seat 3 and the shielding cavity 303 between the cable management seat 3 and the metal shell 1, the cable shielding wire on the cable management seat 3 can extend from the wiring channel 302 into the shielding cavity 303 and contact the inner wall of the metal shell 1 to achieve grounding shielding; at the same time, the shielding cavity 303 is also limited around the shielding wire to prevent it from detaching. The shielded network module provided in this embodiment uses a built-in method to connect the shielding wire to the ground. On the one hand, this arrangement makes it unnecessary to extend the shielding wire to the outside of the metal shell and has a better shielding effect. On the other hand, this arrangement also makes it unnecessary to set a tubular or semi-tubular component on the metal shell 1 to achieve the winding shielding of the shielding wire, that is, the rear end of the metal shell 1 can be set in a plane to shorten its length, so as to realize the short body and small volume design of the shielded network module. The shortening of the length of the shielded network module greatly increases the longitudinal wiring space of the standard panel box during wiring, which is not only more conducive to the wiring of the standard panel box, but also provides conditions for the shielded network module to be installed using the standard panel box for wiring.

[0028] Specifically, Figures 1 to 4 As shown, the rear end of the cable management seat 3 is formed with a wiring portion 31 extending to the rear end wall 111 of the metal shell, and the peripheral wall of the wiring portion 31 is formed with a wire clamping groove extending to its end, and the wire clamping groove forms a wiring channel 301 connecting the cable management seat 3 and the shielding cavity 303; further, the width of the wire clamping groove is set to be smaller to achieve the clamping and fixing of the shielding wire. However, the utility model does not make any limitation to this. In other embodiments, a through hole may also be formed on the peripheral wall of the wiring portion, and a wiring channel is formed at the through hole. Alternatively, in other embodiments, the rear end of the cable management seat may not be fully extended to the rear end wall of the metal shell (that is, the cable management seat is shorter than the metal shell), and a wiring channel is formed between the rear end of the cable management seat and the rear end wall of the metal shell.

[0029] In this embodiment, if Figure 5 As shown, a wire hole 110 for passing the cable is formed on the rear end wall 111 of the metal shell, and a concave cavity 113 is formed between the rear end wall 111 of the metal shell and its peripheral wall 112, and a shielding cavity 303 is formed between the concave cavity 113 and the rear end peripheral wall of the cable management seat 3. However, the utility model does not make any limitation to this. In other embodiments, a shielding cavity can also be formed based on the gap between the inner peripheral wall of the metal shell and the rear end peripheral wall of the cable management seat 3. In order to further increase the space of the shielding cavity 303 so that the shielded wire can be better received in the shielding cavity and abut against the inner wall of the metal shell 1 for grounding and shielding, the present embodiment also provides a rounded shape of the peripheral wall 32 of the cable management seat where the wiring channel 302 is located to increase the space of the shielding cavity 303. However, the utility model does not make any limitation to this.

[0030] In this embodiment, the metal shell 1 includes a shell body 11 and a rear end cover 12 detachably covered on the shell body 11, the shell body 11 covers the module body 2 and the cable management seat 3, a wire hole 110 is formed on the rear end cover 12, and the outer surface of the rear end cover 12 is roughly flat, and the inner wall of the rear end cover 12, the inner wall of the shell body 11 and the rear end peripheral wall of the cable management seat 3 are surrounded to form a shielding cavity 303. The detachable cover of the rear end cover 12 not only greatly facilitates the plug-in connection between the cable management seat 3 and the module body 2, but also the cover-type connection method also makes the metal shell 1 have better shielding performance. However, the utility model does not make any limitation to this. In other embodiments, a metal shell may also be provided, including a shell body and two metal fasteners relatively hinged to the rear end of the shell body, the shell body covers the module body, the two metal fasteners are detachably engaged to form a cable management seat accommodating cavity, and the rear ends of the two are surrounded by a rear end wall having a wire passing hole; in the engaged state, a shielding cavity is formed between the surrounding walls of the two metal fasteners, the surrounded rear end wall, and the rear end outer wall of the cable management seat.

[0031] like Figure 6 As shown, in the shielded network module provided in this embodiment, a plurality of pins 22 are distributed on the top wall of the socket 21, and an anti-insertion protrusion 23 is formed at the rear end of the bottom wall and extends protruding toward the open end of the socket 21, and the anti-insertion protrusion 23 is inserted into the anti-slot position 201 at the front end of the network connector 200. Figure 7 FIG. 2 is a schematic diagram of the structure of a network connector 200 that matches the shielded network module provided in this embodiment; wherein the front end of the network connector 200 is formed with an anti-insertion position 201 that matches the anti-insertion protrusion 23. Figure 7 The network connector 200 shown is inserted into Figure 6 When the shielded network module 100 is shown, the two together form a shielded network connector.

[0032] Although this embodiment Figure 6 The shielded network module shown is used as an example for illustration; however, the present invention does not limit this in any way. In other embodiments, Figure 8 As shown, the top wall of the socket 21 may be provided with a plurality of pins 22, and the bottom wall of the socket may be provided with two slide rails 23' on both sides; the rear ends of the two slide rails 23' each have a rear limit portion 24' protruding toward the center direction of the socket, and the open end of the socket 21 has two front limit portions 25' located on the inner side of the two slide rails 23' and respectively corresponding to the two rear limit portions 24', and a shoulder accommodating groove 26' for engaging the two shoulder spring sheets 201' on the network connector 200' is formed between the front limit portion 24' and the rear limit portion 25' in the insertion direction of the network connector 200'. Fig. 9 Shown with Figure 8The provided shielded network module cooperates with the network connector to form a schematic diagram of the structure of the network connector; the front end of the network connector 200' is inserted into the socket 21' of the shielded network module, and the two shoulder springs 201' of the network connector 200' are engaged in the shoulder receiving groove 26'. Fig. 9 The network connector 200' is shown inserted into Figure 8 When the shielded network module 100 is shown, the two together also constitute another structure of a shielded network connector.

[0033] In summary, in the shielded network module provided by the utility model, a wiring channel connected to the inner cavity of the metal shell is formed at the rear end of the wire management seat, and the shielded wires in the cables engaged on the wire management seat can extend through the wiring channel into the shielding cavity between the outer peripheral wall at the rear end of the wire management seat and the metal shell and be electrically connected to the inner wall of the metal shell to achieve grounding shielding. The provision of the wiring channel and the shielding cavity enables the shielded network module provided by this embodiment to achieve built-in shielding, and the shielding wire no longer needs to extend to the outer wall of the metal shell for grounding. Therefore, the rear end of the metal shell does not need to be provided with a shielding wire winding portion and is roughly planar, shortening the length of the shielded network module to reduce its longitudinal space occupation in the standard panel box, which is more conducive to the wiring of the standard panel box.

[0034] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope required by the claims.
