Problems solved by technology
[0005] 1. Since both the transformer and the common mode suppression module are threaded magnetic bead coils that need to be wound manually, the efficiency of the manual winding method is low, the coil quality is poor, and it is not conducive to automation in the production process, thus resulting in a larger cost for the electrical connector system
[0006] 2. Because the space of the magnetic module is originally limited, and the transformer and the common mode suppression module are surface-mounted or in-line packaged in the magnetic module, this occupies a lot of space, which is not conducive to the precision of the product development trend

The invention claims a combined inductor, which comprises a first substrate and a second substrate, wherein the first substrate is provided with a first accommodation hole in an insertion way; the second substrate is overlapped below the first substrate, and is provided with a second accommodation hole in the insertion way; a first signal wire is sequentially connected with two first conductive connection layers which are communicated by a first conduction element; one of the two first conductive connection layers is arranged on the first substrate, and is enclosed outside the first accommodation hole, and the other is arranged on the second substrate, and is enclosed outside the second accommodation hole; a second signal wire is sequentially connected with two second conductive connection layers which are communicated by a second conduction element; one of the two conductive connection layers is arranged on the first substrate, and is enclosed outside the first conductive connection layer, and the other is arranged on the second substrate, and is enclosed between the second accommodation hole and the first conductive connection layer; and a magnetic core is positioned in each first accommodation hole and each second accommodation hole, thereby fulfilling the aims of automatic operations and inner and outer ring interchange of the signal wires on the adjacent substrates.
Description
【Technical field】 [0001] The invention relates to a combined inductor, in particular to a combined inductor for facilitating automatic operation and reducing time difference between signal transmission intervals. 【Background technique】 [0002] As the network becomes more and more popular, it is an inevitable trend to improve the quality of the network interface, and magnetic modules are indispensable in various types of network interfaces. High-quality magnetic modules can be well matched with the network transceiver control chip to optimize important role in network communication quality. [0003] However, if the signal in the general magnetic module is not processed, there will be problems such as large coupling capacitance, excessive high-frequency components, and large differential mode noise. Most of the industry integrates multiple transformers and multiple common Mode suppression module and other inductance components to solve the problem, the structure of the trans...
