Title: Network transformer

Description:
FIELD 
     The present disclosure relates generally to the field of electronic technology, and more particularly, to a network transformer. 
     BACKGROUND 
     As the rapid development of electronic technology, a network magnetic device which is used in the internet, such as network transformer, is used extensively. A common network transformer generally includes a housing which defines a chamber therein, and coil components provided in the chamber. The network transformer generally plays an important role in signal transmission, impedance matching, waveform repairing, clutter signal suppression and high voltage isolation. In order to realize the above functions, the network transformer may include ten to twenty coil components as needed, and at this point, the insulating capability between lines in the network transformer and anti-interference capability between input and output channels will directly affect the quality of the network transformer itself. To overcome these disadvantages, common practice is to configure the coil components to be connected in the chamber in a certain order and to insulate and encapsulate the coil components in a glue-pouring way, so as to achieve the insulating capability and the anti-interference capability. But such a network transformer demands high quality due to the fact that all the coil components are placed in a same space, and though the insulating capability has been achieved, anti-interference capability between internal channels still remains to be solved. 
     SUMMARY 
     In view of the above, an objective of the present disclosure is to provide a network transformer, which can improve insulating effect and anti-interference capability between internal channels, and be conducive to make full use of the product space. 
     Described herein is a network transformer, including a housing and a partition member, wherein the housing defines a chamber therein, a plurality of external pins are provided at edge of the housing, the partition member is mounted in the chamber and divides the chamber into two spaces, in each of which a plurality of magnetic cores are mounted, the magnetic core is winded at least with a coil, and the external pin is connected to the end of the coil. 
     Compared with the conventional network transformer which places the coil components in a same space, the network transformer described herein can enhance the anti-interference capability between internal channels of the transformer to ensure product quality via forming a double-floor space structure by the partition member and providing each floor space with magnetic cores. In addition, the network transformer described herein also can make full use of the product space, improve space utilization of the chamber, and ensure the insulation distance between the ends of the coils out from the magnetic cores and the insulation distance between the different functional magnetic cores. 
     Also described herein is a network transformer wherein the partition member is provided with a plurality of wiring grooves arranged spaced apart from one another along the arranging direction of the external pins, the external pins are on a same plane serving as a reference plane, and one side of the partition member where the wiring grooves are provided faces towards the reference plane. The configuration of the wiring grooves can be beneficial to better ensure the product quality of insulation distance between the ends of the coils out from the magnetic cores. 
     Also described herein is a network transformer wherein the partition member is provided with a plurality of bumps arranged spaced apart from one another, and the wiring groove is formed by two adjacent bumps. 
     Also described herein is a network transformer wherein the partition member is provided with at least two rows of bumps, there is a space interval between every two adjacent bumps in each row of bumps, and the space intervals formed by one row of bumps correspond with those formed by other rows of bumps, so as to form the wiring grooves. 
     In conclusion, the distance between the two adjacent wiring grooves can further ensure the insulation distance. 
     Also described herein is a network transformer wherein the housing includes a top surface portion, two first side surface portions disposed opposite to each other and two second side surface portions disposed opposite to each other, tops of the two first side surface portions and the two second side surface portions are respectively connected to the top surface portion to form the chamber, the external pins are provided at bottom edge of the first side surface portions, and the partition member is parallel to the top surface portion. The partition member can thus divide the chamber into two spaces by the above structure. 
     Also described herein is a network transformer wherein the chamber is provided with a support plate connected to the top surface portion and the first side surface portions, and the partition member is mounted in the chamber by the support plate. 
     Also described herein is a network transformer wherein the support plate has an end face cooperative with the partition member, the end face is provided with a protrusion, the partition member is provided with a cavity configured to engage with the protrusion. 
     Therefore, the partition member can be more firmly mounted in the chamber and divide the chamber into two spaces by the supporting of the support plate and the cooperation of the protrusion and the cavity. 
     Also described herein is a network transformer wherein the chamber is provided with a support plate connected to the first side surface portion, and a top of the support plate is provided with a stepped surface cooperative with the partition member. 
     Also described herein is a network transformer wherein the second side surface portion is provided with a hole, and a side of the partition member is provided with a convex column configured to engage with the hole. 
     Also described herein is a network transformer wherein an inner wall of the second side surface portion is provided with a projection configured to support the partition member. 
     Therefore, the partition member can be also more firmly mounted in the chamber and divide the chamber into two spaces by the supporting of the stepped surface of the support plate and the projection and the engagement between the hole and the convex column. 
     The network transformer described herein has the following advantages. 
     The anti-interference capability between internal channels of the transformer can be effectively improved to solve the quality problem exiting in a conventional network transformer, by a double-floor space structure formed by the partition member; and 
     The double-floor space structure formed by the partition member is conducive not only to save product space to improve space utilization of the chamber, but also to ensure the insulation distance between the ends of the coils out from the magnetic cores and the insulation distance between different functional magnetic cores to further ensure product quality.
