Title: Multiple socket panel device with anti-crosstalk shielding structure

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The invention relates to a socket structure, and more particularly to a multiple socket panel device with anti-crosstalk shielding structure. 
     Description of the Related Art 
     In a typical network room, it is constructed by various network equipment installed in a cabinet, which includes switches, panels, jumpers, network cables and other equipment, thereby constructing systems and environments of network communications. 
     According to the international standard settings, the network system is divided into two types: shielded and non-shielded. In the setting of the shielded system, the shield structure must be used to isolate external interference, and the interference signal is guided by grounding. Therefore, there will be a ground wire or a braided net in the setting of the network line. In addition to the ground wire or braided net in the jumper, the connectors on both ends of the wire will also be provided with a shield structure, such as an iron sheet which is connected to the ground wire, and there will also be a ground wire on the panel, so that when the jumper is inserted into the panel, the grounding effect is continuous, thereby completing the shielding effect. On the contrary, the panel, the jumper and the network cable of the non-shielding system will not be provided with the shielding structure. 
     However, with the progress of the times, while the network frequency requirements are getting higher and higher, the relevant international specifications have also evolved, and the two systems also need to be upgraded. However, as the frequency increases, the crosstalk interference, the self-generated interference or the foreign interference, is relatively increased, especially the international standard has set the Alien crosstalk test standard. No matter the non-shielded system is on the wire or the panel, it will encounter the problem of external crosstalk interference. 
     In the conventional technology of the panel, an anti-external crosstalk structures for panel as disclosed in U.S. Pat. No. 7,288,001. The space shielding is used to cover non-adjacent signal contact groups with a shielding cover. Although the shielding method is used, it can still block the signals between adjacent signal contact groups. However, this method has the disadvantage that although it will not be affected by adjacent signal connections because there is no signal contact structure covered by the shielding cover, it may be interfered by the signals from other equipment, especially in the current situation where the equipment room equipment is arranged more and more closely. 
     Another anti-external crosstalk structures for panel as disclosed in U.S. Pat. No. 7,878,824. An isolation structure is added between multiple signal contact groups, such as a metal sheet, or the inner wall of the housing of the signal contact group is directly plated by metal to form an isolation layer. However, with a metal material as the separator, its structure is only set between the jacks, and it is not effective to isolate the external crosstalk from other directions. If the metal plating is used on the inner wall of the housing, in addition to the environmental pollution caused by metal plating, its cost is relatively high. 
     BRIEF SUMMARY OF THE INVENTION 
     In view of the above-mentioned shortcomings, the main object of the invention is to provide a multi-socket panel device with an anti-crosstalk shielding structure. A shield sleeve made of a metal material is set on the outside of the socket to prevent adjacent sockets crosstalk interference from all directions. In addition to effectively protecting external interference, this structure can also reduce production costs and production time. 
     The invention provides a multiple socket panel device with anti-crosstalk shielding structure, including a main base body having an accommodation space therein; a plurality of socket sets corresponding to the main base body, wherein each socket set further comprises: a substrate; a plurality of prick type terminals provided on both sides of a surface of the substrate, and the prick type terminals penetrate the substrate to the other surface; a plurality of sockets provided on the other surface of the substrate and combined to the main body, wherein each socket comprises a jack, and a plurality of wire terminals for electrical connection provided in the jack and connected with the plurality of prick type terminals provided on the substrate to form electrical conduction; a plurality of shielding sleeve bases connected to each socket, wherein the shielding sleeve bases are made of metal material; a back plate correspondingly combined with the main base body, and covers the socket sets and the shield sleeve.
