Description

Technical Field

[0001] The present application belongs to the technical field of communication equipment, and specifically relates to a shielding structure of a cable connector and a cable connector. Background Art

[0002] With the rapid development of communication equipment, cable connectors have become the main components of high-speed signal transmission in the next generation of switches. Groundless high-speed bare wires have become an important part of cable connectors because of their technical advantages such as high transmission rate, small size and low production cost.

[0003] Compared with the form with ground wire, the reference return ground of the signal without ground wire is mainly realized by the aluminum foil or copper foil on the outside of the cable. Since the thickness of aluminum foil or copper foil is very thin, it is easy to be broken by laser, so it is difficult to weld aluminum foil or copper foil by laser; the other tin welding process is relatively expensive and the process is relatively complicated. Therefore, the reliable electrical connection between aluminum foil or copper foil and the metal shielding sheet of the cable connector has become one of the difficulties that need to be overcome in the current groundless high-speed bare wire. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a shielding structure of a cable connector and a cable connector, which can solve the problems that the aluminum foil or copper foil of the outer shielding layer of the cable is easily punctured by laser welding, and the tin welding cost is high and the process is complicated.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] The embodiment of the present application provides a shielding structure of a cable connector, the shielding structure comprising: a shielding shell, a limiting member and an elastic conductive member;

[0007] The limiting member and the elastic conductive member are both arranged in the shielding shell, and the limiting member and the elastic conductive member are correspondingly arranged in a first direction, and the elastic conductive member is used for elastically contacting with the shielding layer of the cable limited by the limiting member.

[0008] An embodiment of the present application further provides a cable connector, comprising the shielding structure of the above-mentioned cable connector.

[0009] In the embodiment of the present application, the elastic connector can be in elastic contact with the shielding layer of the cable, so as to achieve a reliable connection between the shielding layer and the shielding structure, realize signal reflux, and thus ensure the stability of signal transmission; the limiter can limit the cable to prevent the cable from moving arbitrarily and affecting its good contact with the elastic conductive member; the shielding shell can shield the electrical connection of the cable. Based on the above settings, compared with laser welding or tin welding processes, there is no need for welding between the cable and the shielding structure in the embodiment of the present application, but elastic contact with elastic conductive members is adopted, so that the shielding layer will not be punctured by the laser, thereby ensuring the integrity of the shielding layer, and having lower costs and reduced operational complexity compared to the tin welding process, so that the connection method in the embodiment of the present application has a more obvious technical advantage over laser welding or tin welding.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0029] refer to Figures 1 to 8The embodiment of the present application discloses a shielding structure 100 of a cable connector, which is applied to the connection area between a cable 200 and a cable connector. The cable 200 may be a groundless cable, which has a shielding layer 210. The shielding layer 210 may be a metal layer, such as an aluminum foil layer, a copper foil layer, etc. Of course, it may also be in other forms. The specific material of the shielding layer 210 is not specifically limited here, as long as it can achieve the signal transmission effect; in addition, the cable 200 may also include a core wire 220, through which an electrical connection can be achieved. The disclosed shielding structure 100 includes a shielding shell 110, a limiter 120 and an elastic conductive member 130.

[0030] The shielding shell 110 is a basic component of the shielding structure 100, which can provide an installation foundation for components such as the stopper 120 and the elastic conductive member 130. In some embodiments, the stopper 120 and the elastic conductive member 130 are both disposed in the shielding shell 110 to achieve installation of the stopper 120 and the elastic conductive member 130.

[0031] Exemplarily, the limit member 120 and the elastic conductive member 130 are respectively independent of the shielding shell 110, that is, the limit member 120, the elastic conductive member 130 and the shielding shell 110 are respectively manufactured independently, and the limit member 120 and the elastic conductive member 130 are later fixedly installed to the inner wall of the shielding shell 110 respectively to ensure the stability of the limit member 120 and the elastic conductive member 130. This method can reduce the difficulty of manufacturing.

[0032] Of course, the limiting member 120 and the elastic conductive member 130 can also be manufactured integrally with the shielding shell 110, that is, when the shielding shell 110 is manufactured, the limiting member 120 and the elastic conductive member 130 are formed together, which can shorten the manufacturing cycle.

[0033] To ensure that the cable 200 can accurately and stably contact the elastic conductive member 130, in the embodiment of the present application, the limit member 120 and the elastic conductive member 130 are arranged correspondingly in the first direction. In this way, the elastic conductive member 130 can elastically contact the shielding layer 210 of the cable 200 limited by the limit member 120. On the one hand, the good contact between the elastic conductive member 130 and the shielding layer 210 can be ensured. On the other hand, the cable 200 can be ensured not to move at will under the limiting action of the limit member 120, thereby limiting the shielding layer 210 of the cable 200 to be in good contact with the elastic conductive member 130 at all times.

[0034] It should be noted here that the above-mentioned first direction can be the extension direction of a certain length of the cable 200 inside the shielding shell 110, that is, one end of the cable 200 extends into the shielding shell 110 and then extends along the first direction, and is limited by the limiting member 120 and is in good contact with the elastic conductive member 130.

[0035] In some embodiments, the shielding shell 110 can be a metal shell to play the role of conducting electricity, shielding signals, etc.; the limiting member 120 can be made of metal or non-metal material, as long as it can limit the outer wall of the cable 200, and the specific material is not limited. In addition, the limiting member 120 can be a rigid member or an elastic member; the elastic conductive member 130 can be a metal spring, of course, it can also be a non-metallic conductive structure, as long as it has elastic and conductive properties, and the specific form is not limited.

[0036] In an embodiment of the present application, the elastic connecting member can elastically contact the shielding layer 210 of the cable 200, thereby achieving a reliable connection between the shielding layer 210 and the shielding structure 100, realizing signal backflow, and thereby ensuring the stability of signal transmission; the limiting member 120 can limit the cable 200 to prevent the cable 200 from moving at will and affecting its good contact with the elastic conductive member 130; the shielding shell 110 can shield the electrical connection of the cable 200.

[0037] Based on the above settings, compared with laser welding or tin welding processes, the cable 200 and the shielding structure 100 in the embodiment of the present application do not need to be welded, but elastic contact is achieved through an elastic conductive part 130, so that the shielding layer 210 will not be pierced by the laser, thereby ensuring the integrity of the shielding layer 210. Compared with the tin welding process, it has a lower cost and reduces the complexity of operation, so that the connection method in the embodiment of the present application has a more obvious technical advantage over laser welding or tin welding.

[0038] In some embodiments, the limiting member 120 may include a limiting groove extending along the first direction, and a limiting space 123 may be formed in the limiting groove to accommodate and limit the cable 200. Exemplarily, the notch of the limiting groove is consistent with the width of the groove bottom, that is, the size of the limiting groove is uniform, and this design can facilitate the placement of the cable 200 in the limiting groove; of course, the width of the notch of the limiting groove can also be slightly smaller than the width of the groove bottom. This design can play a certain clamping role on the cable 200 through the edge of the notch, and to a certain extent, it can effectively alleviate the problem of the cable 200 escaping from the limiting groove.

[0039] Under actual working conditions, the width of the limit groove can be equal to or slightly smaller than the diameter of the cable 200. This design can squeeze the outer wall of the cable 200 through the side wall of the limit groove, thereby ensuring the stability of the cable 200 and preventing the cable 200 from escaping from the limit groove.

[0040] Of course, the width of the limiting groove can also be made slightly larger than the diameter of the cable 200. This design can form a certain gap between the outer wall of the cable 200 and the side wall of the limiting groove. In this way, it can not only play a limiting role, but also facilitate the placement or removal of the cable 200.

[0041] Optionally, in the first direction, the limiting groove is located on at least one side of the elastic conductive member 130. Specifically, the limiting groove can be located upstream of the elastic conductive member 130 along the extension direction of the cable 200 into the shielding shell 110. In this way, the cable 200 can be limited by the limiting groove first, and then the shielding layer 210 of the cable 200 can be elastically contacted with the elastic conductive member 130; it can also be that the limiting groove can be located downstream of the elastic conductive member 130 along the extension direction of the cable 200 into the shielding shell 110. In this way, the shielding layer 210 of the cable 200 can be elastically contacted with the elastic conductive member 130 first, and then the cable 200 can be limited by the limiting groove; it can also be that the limiting members 120 are respectively provided upstream and downstream of the elastic conductive member 130 along the extension direction of the cable 200 into the shielding shell 110. This design can limit the cable 200 at both ends of the elastic conductive member 130 respectively to improve the limiting stability of the cable 200.

[0042] In addition, the number of limiting grooves on each side of the elastic conductive member 130 can be one, two or more, which can be selected according to actual working conditions. The more limiting grooves there are, the better the limiting effect on the cable 200 and the higher the stability of the cable 200.

[0043] refer to Figure 1 In some embodiments, the inner wall of the shielding shell 110 is provided with a first limiting protrusion 121 and a second limiting protrusion 122, wherein the first limiting protrusion 121 and the second limiting protrusion 122 are arranged at intervals in the second direction, wherein the second direction is perpendicular to the first direction. The first limiting protrusion 121 and the second limiting protrusion 122 protrude from the inner wall of the shielding shell 110 respectively, and a certain limiting space 123 is formed between the two to accommodate the cable 200, thereby limiting the cable 200 in the second direction.

[0044] In the embodiment of the present application, the first limiting protrusion 121 and the second limiting protrusion 122 serve as two side walls of the limiting groove in the second direction, and are respectively used to contact or form a gap with the outer walls on both sides of the cable 200 in the second direction.

[0045] Based on the above configuration, the outer walls on both sides of the cable 200 can be limited in the second direction by the first limiting protrusion 121 and the second limiting protrusion 122 to prevent the cable 200 from moving randomly in the second direction and affecting the elastic contact between the shielding layer 210 and the elastic conductive member 130 .

[0046] When the first limiting protrusion 121 and the second limiting protrusion 122 are in contact with the outer walls on both sides of the cable 200 in the second direction respectively, the stability of the cable 200 can be guaranteed; when at least one of the first limiting protrusion 121 and the second limiting protrusion 122 forms a gap with the outer walls on both sides of the second cable 200 in the second direction, although the cable 200 can move slightly in the second direction, it hardly affects the good elastic contact between the shielding layer 210 and the elastic conductive part 130, and it is also beneficial for the cable 200 to be placed in or taken out of the limiting groove.

[0047] Exemplarily, at least one of the first limiting protrusion 121 and the second limiting protrusion 122 may be an elastic member, which may be elastically deformed when squeezed by the cable 200 , so as to facilitate the cable 200 to move into or out of the limiting space 123 .

[0048] In some embodiments, the first limiting protrusion 121 and the second limiting protrusion 122 are respectively integrally provided with the shielding shell 110, that is, when the shielding shell 110 is manufactured, the first limiting protrusion 121 and the second limiting protrusion 122 are formed together, for example, by adopting a manufacturing process such as casting; or the first limiting protrusion 121 and the second limiting protrusion 122 can be directly formed by machining after the shielding shell 110 is manufactured, for example, by adopting machining, bending and other processes to form the first limiting protrusion 121 and the second limiting protrusion 122.

[0049] In some other embodiments, after the shielding shell 110 is manufactured, the independent first limiting protrusion 121 and the second limiting protrusion 122 can be fixedly connected to the shielding shell 110, for example, by welding, bonding, riveting, screwing, etc.

[0050] In a more specific embodiment, the side wall of the shielding shell 110 can be cut, specifically, two relative connecting pieces can be cut along a concave trajectory, and then the two connecting pieces are bent toward the inside of the shielding shell 110 to form a first limiting protrusion 121 and a second limiting protrusion 122, respectively; at the same time, a first through hole 1111 is formed on the side wall of the shielding shell 110 after bending.

[0051] In some embodiments, the elastic conductive member 130 may be a metal spring, and the metal spring includes a first end 131 and a second end 132 that are disposed opposite to each other along a first direction. Figure 1As shown, the first end 131 is connected to the shielding shell 110, and the second end 132 is freely arranged and used to elastically contact with the shielding layer 210. Based on this, the first end 131 is connected to the shielding shell 110 to achieve the fixation of the elastic conductive member 130, and the second end 132 is elastically contacted with the shielding layer 210 to ensure good conductivity. At the same time, the good contact between the elastic conductive member 130 and the shielding layer 210 can also be ensured under the elastic effect.

[0052] Exemplarily, the second end 132 of the metal spring can be bent to form a convex portion, which is used to contact the shielding layer 210, so as to improve the good contact with the shielding layer 210. In addition, the cross-sectional area of ​​the second end 132 of the metal spring can also be larger than the cross-sectional area of ​​the first end 131, so as to increase the contact area between the metal spring and the shielding layer 210, thereby ensuring good contact.

[0053] Optionally, the metal spring and the shielding shell 110 can be integrally provided, in which case the shielding shell 110 is also made of metal, that is, the metal spring can be formed together when the shielding shell 110 is manufactured, for example, by machining, bending and other processes.

[0054] In some other embodiments, after the shielding shell 110 is manufactured, the independent metal spring sheet may be fixedly connected to the shielding shell 110 , for example, by welding, bonding, riveting, screwing, etc. to fix the metal spring sheet.

[0055] In a more specific embodiment, the shielding shell 110 can be cut, and specifically, the metal spring piece can be cut along a concave trajectory. At the same time, after cutting off part of the material, a second through hole 1112 will be formed on the side wall of the shielding shell 110. Due to the existence of the second through hole 1112, the metal spring piece can be elastically deformed toward the cable 200 or away from the cable 200, so as to maintain good elastic contact with the shielding layer 210.

[0056] In other embodiments, the elastic conductive member 130 may also be conductive foam or conductive rubber, and the conductive foam or conductive rubber is elastically and electrically connected between the shielding layer 210 and the shielding shell 110. Considering that the conductive foam or conductive rubber has conductivity and elasticity, when the cable 200 is placed in the shielding structure 100, the limiter 120 can limit the cable 200, and the conductive foam or conductive rubber is in elastic contact with the shielding layer 210 and the shielding shell 110 of the cable 200, respectively, to ensure good contact and further ensure good conductivity.

[0057] Taking into account that multiple bundles of cables 200 are simultaneously connected to the shielding structure 100, the shielding structure 100 in the embodiment of the present application may include multiple groups of limit members 120 and multiple elastic conductive members 130, wherein the multiple groups of limit members 120 and the multiple elastic conductive members 130 are each arranged at intervals in a second direction perpendicular to the first direction, and each group of limit members 120 and the corresponding elastic conductive members 130 are arranged correspondingly in the first direction.

[0058] Based on the above configuration, multiple bundles of cables 200 can be placed in multiple sets of limiting members 120 respectively, and the multiple bundles of cables 200 can be limited and fixed by the multiple sets of limiting members 120 respectively to ensure that the multiple bundles of cables 200 will not move arbitrarily or detach from the shielding structure 100; at the same time, the multiple bundles of cables 200 are also in contact with the multiple elastic conductive members 130 respectively to achieve elastic and electrical connection to realize signal reflux.

[0059] In other embodiments, multiple cables 200 may share one elastic conductive member 130. In this case, the elastic conductive member 130 is relatively large and can contact multiple cables 200 at the same time. This method can also achieve electrical connection to facilitate signal return.

[0060] Furthermore, each group of limiters 120 includes at least one limiter 120, and the specific number can be set according to the actual working conditions. In order to improve the limit stability, each group can include multiple limiters 120, and the multiple limiters 120 are arranged along the first direction. In this case, the same bundle of cables 200 can be limited and fixed by multiple limiters 120 at the same time, so as to ensure the stability of the cables 200. Of course, when the space of the shielding shell 110 is relatively cramped, a limiter 120 can also be set, and a bundle of cables 200 can be limited and fixed by a limiter 120. In this case, both the space requirements can be met and the limit stability can be ensured.

[0061] In addition, when each group includes multiple limit members 120, the multiple limit members 120 and the corresponding elastic conductive members 130 are arranged along the first direction. At this time, the elastic conductive member 130 can be located between two adjacent limit members 120. Of course, it can also be located at one end of the multiple limit members 120. The specific arrangement method can be selected according to the actual working conditions.

[0062] refer to Figure 2 and Figure 3In some embodiments, the shielding shell 110 may include a first shielding sheet 111, a second shielding sheet 112, and a connecting plate 113, wherein the first shielding sheet 111 and the second shielding sheet 112 are spaced apart along the third direction, and the connecting plate 113 is connected between the first shielding sheet 111 and the second shielding sheet 112. A shielding space 114 may be enclosed by the first shielding sheet 111, the second shielding sheet 112, and the connecting plate 113, and the connection end of the cable 200 extends into the shielding space 114, which may play a role in signal shielding.

[0063] In addition, when the end of the cable assembly 300 is connected to the shielding shell 110 , the end of the cable assembly 300 also extends into the shielding space 114 to perform a signal shielding function.

[0064] Exemplarily, the first shielding sheet 111 and the second shielding sheet 112 are both rectangular plates, the connecting plate 113 is a strip plate, the first shielding sheet 111 and the second shielding sheet 112 are arranged in parallel and spaced a certain distance apart, and both are connected at both ends of the second direction by the connecting plate 113, and the connecting plate 113 plays a supporting role. Through this arrangement, a rectangular shielding shell 110 is formed, and the two ends of the shielding shell 110 in the first direction are connected, so as to extend from one end into the cable 200 and from the other end into the cable assembly 300, so as to achieve electrical connection and signal return.

[0065] Considering that the limiting member 120 is disposed in the shielding shell 110, in some embodiments, the limiting member 120 can be disposed on at least one of the first shielding sheet 111 and the second shielding sheet 112. Exemplarily, the limiting member 120 can be disposed on a side of the first shielding sheet 111 facing the second shielding sheet 112, and extend toward the second shielding sheet 112, so as to form a limiting space 123 that limits the cable 200; of course, the limiting member 120 can also be disposed on a side of the second shielding sheet 112 facing the first shielding sheet 111, and extend toward the first shielding sheet 111, so as to form a limiting space 123 that limits the cable 200.

[0066] In order to further improve the limiting stability of the cable 200, the limiting member 120 can also be simultaneously arranged on the side of the first shielding piece 111 facing the second shielding piece 112, and on the side of the second shielding piece 112 facing the first shielding piece 111. In this way, when the cable 200 extends into the shielding shell 110, the cable 200 can be limited by the limiting member 120 on the first shielding piece 111 and the limiting member 120 on the second shielding piece 112 at the same time, thereby further improving the limiting stability to prevent the cable 200 from moving at will or detaching from the shielding shell 110.

[0067] Furthermore, the limiting member 120 on the first shielding piece 111 and the limiting member 120 on the second shielding piece 112 may be arranged relative to each other in the third direction, or may be arranged in a staggered manner, which may be specifically set according to actual working conditions.

[0068] Considering that the elastic conductive member 130 is disposed in the shielding shell 110, in some embodiments, the elastic conductive member 130 can be disposed on at least one of the first shielding sheet 111 and the second shielding sheet 112. Exemplarily, the elastic conductive member 130 can be disposed on the side of the first shielding sheet 111 facing the second shielding sheet 112, and elastically protrude toward the second shielding sheet 112, so as to elastically and electrically contact the shielding layer 210 of the cable 200; of course, the elastic conductive member 130 can also be disposed on the side of the second shielding sheet 112 facing the first shielding sheet 111, and elastically protrude toward the first shielding sheet 111, so as to elastically and electrically contact the shielding layer 210 of the cable 200.

[0069] In order to further improve the contact between the elastic conductive member 130 and the shielding layer 210 of the cable 200, the elastic conductive member 130 can also be simultaneously arranged on the side of the first shielding sheet 111 facing the second shielding sheet 112, and on the side of the second shielding sheet 112 facing the first shielding sheet 111. In this way, when the cable 200 extends into the shielding shell 110, the elastic conductive member 130 on the first shielding sheet 111 and the elastic conductive member 130 on the second shielding sheet 112 can simultaneously be in elastic and electrical contact with the shielding layer 210 of the cable 200, thereby further improving the contact quality and preventing the occurrence of false connection.

[0070] Furthermore, the elastic conductive member 130 on the first shielding sheet 111 and the elastic conductive member 130 on the second shielding sheet 112 may be arranged relative to each other in the third direction, or may be arranged in a staggered manner, which may be specifically set according to actual working conditions.

[0071] refer to Figure 1 In some more specific embodiments, the limiting member 120 and the elastic conductive member 130 are both disposed on the first shielding piece 111, and the second shielding piece 112 is used to abut against the cable 200 limited by the limiting member 120. Based on this, the limiting member 120, the first limiting piece and the second shielding piece 112 can enclose a limiting space 123 to limit the cable 200 located in the limiting space 123 in all directions, thereby ensuring the stability of the cable 200.

[0072] refer to Figure 4 and Figure 5In order to adapt to the connection of multiple bundles of cables 200 with the shielding structure 100, the shielding shell 110 may include multiple connecting plates 113, and the multiple connecting plates 113 are arranged at intervals in the second direction perpendicular to the first direction. Each adjacent two connecting plates 113, the first shielding sheet 111 and the second shielding sheet 112 form an accommodating channel, and the accommodating channel is used to penetrate the cable assembly 300. Based on this arrangement, multiple cable assemblies 300 can be penetrated through the multiple accommodating channels of the shielding shell 110, so that the mechanical connection and electrical connection of the multiple cable assemblies 300 can be achieved.

[0073] Correspondingly, the shielding structure 100 may include multiple groups of limiting members 120 and multiple elastic conductive members 130. Each group of limiting members 120, each elastic conductive member 130 and each accommodating channel are arranged correspondingly in the first direction. In this way, each bundle of cables 200 limited by each group of limiting members 120 can be arranged correspondingly with the cable assembly 300 to facilitate connection.

[0074] It should be noted here that the specific structure of the cable assembly 300 and its connection with the shielding structure 100, the cable 200 and other components can be referred to in related technologies and will not be described in detail here.

[0075] refer to Figures 4 to 6 In some embodiments, the first shielding sheet 111 may be provided with a first fixing hole 1113, the second shielding sheet 112 may be provided with a second fixing hole 1121, and the second fixing hole 1121 is arranged corresponding to the first fixing hole 1113, one end of the connecting plate 113 in the third direction penetrates into the first fixing hole 1113 and is fixedly connected to the first shielding sheet 111, and the other end of the connecting plate 113 in the third direction penetrates into the second fixing hole 1121 and is fixedly connected to the second shielding sheet 112.
