Technical Field

[0002] An existing network connector is provided with an isolation transformer and a Bob Smith circuit. The isolation transformer is mainly a coil wound by two magnetic rings, one large and one small, and four twisted enameled wires. The isolation transformer is welded on a PCB board and assembled on the middle frame of the network connector. The Bob Smith circuit mainly includes four resistors and a high-voltage isolation capacitor. One pin of the high-voltage isolation capacitor needs to be connected to the impedance matching resistor on the PCB, and the other pin needs to be connected to the shielding shell of the network connector. For some upper and lower multi-port RJ45 connectors, the isolation transformer and the Bob Smith circuit need to be set in pairs, so it is necessary to set a pair of high-voltage isolation capacitors.

[0003] In the prior art, high-voltage isolation capacitors can be made of chip capacitors, but the surface of chip capacitors is easily affected by environmental humidity, pollution and other factors, resulting in a decrease in high-voltage isolation capability or even failure. In addition, one pin of the high-voltage isolation capacitor needs to be connected to the shielding shell, so a lead needs to be connected to the shielding shell for the chip capacitor, which is troublesome to manufacture.

[0037] Reference Figure 1 , which is an exploded schematic diagram of a middle frame component of an existing network connector, which includes a network connector middle frame 100, a plug-in capacitor 200 and a PCB board 300, the PCB board 300 is arranged on the left and right sides of the network connector middle frame 100, and the plug-in capacitor 200 is arranged at one end of the network connector middle frame 100 along the up and down direction.

[0038] Reference Figures 2 to 6 , which is a schematic diagram of the structure of the network connector middle frame 100 improved and formed according to an embodiment of the present invention. The network connector middle frame includes a middle frame body 110 and a capacitor installation forming part 120. The capacitor installation forming part 120 is arranged at one end of the middle frame body 110, and the capacitor installation forming part 120 is provided with a capacitor body side-by-side concave cavity 121, a middle pin plug hole 122, and side pin plug holes 123 arranged on the left and right sides of the middle pin plug hole 122. The middle pin plug hole 122 and the side pin plug hole 123 are through holes and one end of the side pin plug hole 123 is through-hole and penetrates to the side wall of the side concave cavity 121 of the capacitor body. The capacitor installation forming part 120 is provided with a first curved positioning surface 124 at the other end opening corresponding to the middle pin plug hole 122, and the capacitor installation forming part 120 is provided with a second curved positioning surface 125 at the other end opening corresponding to the side pin plug hole 123.

[0039] When installing the plug-in capacitor 200, the capacitor body 210 of the plug-in capacitor 200 can be installed in parallel in the capacitor body parallel cavity 121, and the pins 220 of the plug-in capacitor 200 that are close to each other are inserted into the middle pin plug hole 122, and pass through the other end of the middle pin plug hole 122, and are bent and formed through the first curved positioning surface 124, and the pins 220 of the two plug-in capacitors 200 that are far away from each other are respectively inserted into the side pin plug holes 123, and pass through the other end of the side pin plug holes 123, and then are bent and formed through the second curved positioning surface 125, thereby completing the installation of the plug-in capacitor 200.

[0040] The above-mentioned network connector middle frame 100 and capacitor installation forming part 120 can assist in the installation of the plug-in capacitor 200. Positioning installation can be achieved through the arrangement of the capacitor body side-by-side concave cavity 121 and pin jack. At the same time, through the arrangement of the pin jack and the curved positioning surface, the pin 220 can be conveniently and accurately bent and formed, so that the installation process of the entire plug-in capacitor 200 is convenient, the installation consistency is good, and the efficiency is high. In addition, the above-mentioned middle frame structure is adopted, and due to the good positioning of the installation, it is convenient to realize automated production such as automated assembly and molding through automated equipment. Furthermore, through the arrangement of the jack and the positioning surface, the plug-in capacitor 200 is installed by snapping after the pin 220 is bent, and the installation of the plug-in capacitor 200 is stable.

[0041] In the embodiment, there is one middle pin socket 122 and two side pin sockets 123. A single middle pin socket 122 can be used to simultaneously allow two pins 220 of two plug-in capacitors 200 that are close to each other to be plugged in at the same time. The two pins 220 are close together when formed, which is convenient for external connection ends of the shielding shell. At the same time, it can also avoid setting more holes. The middle pin socket 122 is a single hole because there is no need to consider the partition wall between the holes when there are multiple holes, so it can be made larger, which is convenient for the pins 220 to be assembled. Of course, it is conceivable that in some embodiments, two middle pin sockets 122 are also allowed to be set for the pins 220 to be plugged in independently, and the above-mentioned settings still belong to the protection scope of the present invention.

[0042] In the embodiment, one end of the middle pin insertion hole 122 and one end of the side pin insertion hole 123 are provided with a guide chamfer, so as to facilitate smooth insertion of the pin 220 .

[0043] In an embodiment, the first bending positioning surface 124 is the end surface of the capacitor mounting and forming portion 120, and the other end of the middle pin jack 122 penetrates to this end surface. In the embodiment, the middle frame body 110 is provided with a tail end 111, the first bending positioning surface 124 is the end surface corresponding to the tail end 111 of the middle frame body 110, and the first bending positioning surface 124 is lower than the tail end 111. With the above structure, after the pins 220 of the capacitor are bent and formed, they can be not protruded from the tail end 111, so that the appearance of the component is regular and it is also convenient to realize subsequent automated operation.

[0044] In an embodiment, a positioning slot 126 is provided at the circumferential position of the orifice at the other end of the side pin jack 123, and the second bending positioning surface 125 is the bottom surface of the positioning slot 126. By using the positioning slot 126, the pins 220 can be bent in a positioned manner. The pins 220 are restricted by the positioning slot 126, and the bending position is more accurate, which is convenient for subsequent accurate connection with the PCB board 300.

[0045] In an embodiment, the two side pin jacks 123 are at the same height position, and the middle pin jack 122 is at another height position. With the above structure, the three pin jacks can form an up-and-down dislocation of a "pin" shape structure, which can adapt to the structure of the pins 220 of the commonly used plug-in capacitor 200 with different heights, and is beneficial to smooth assembly.

[0046] In an embodiment, two convex portions 127 arranged side by side at intervals are provided on the cavity side wall of the capacitor body side-by-side concave cavity 121. The convex portions 127 are used to be inserted into the position between the two pins 220 of the plug-in capacitor 200 and abut against the capacitor body 210, so as to better position the plug-in capacitor 200.

[0047] In an embodiment, the capacitor mounting and forming portion 120 includes a base portion 128 and two baffles 129. The base portion 128 and the two baffles 129 are connected to the end surface of the middle frame body 110. One ends of the two baffles 129 are connected to one end of the base portion 128. The two baffles 129 are arranged side by side at intervals on the left and right. A capacitor body side-by-side concave cavity 121 is formed by enclosing between the two baffles 129 and the base portion 128. The middle pin jack 122 and the side pin jack 123 are arranged on the base portion 128. The structure of the above capacitor mounting and forming portion 120 is simple and easy to implement. In the embodiment, the left convex portion 127 and the right convex portion 127 are connected to one end of the base portion 128.
