In a standard RJ45 electrical connector, the printed circuit board of the electrical connector is usually located at the bottom of the electrical connector. In this case, the terminals connected to the printed circuit board of the electrical connector can be directly connected to the main printed circuit board located below the electrical connector, thereby realizing the transmission of signals and / or data.

[0055] The following will describe in detail some embodiments of the electrical connector of the present application in conjunction with the accompanying drawings. For the sake of clarity and simplicity, the drawings mark the insertion direction X of the mating connector (e.g., a plug) inserted into the electrical connector of the present application, the vertical direction Y perpendicular to the insertion direction X, and the lateral direction Z perpendicular to both the insertion direction X and the vertical direction Y.
[0056] According to one aspect of the present application, an electrical connector is provided, the electrical connector being a modular jack incorporating an internal printed circuit board to provide capacitance compensation. In some examples, an RJ45 connector is an example of a modular jack.
[0057] like Figure 1 As shown, the electrical connector 1 is used to accommodate a mating connector (such as a plug) in a manner that the tab of the mating connector (such as a plug) is inserted into the electrical connector in a side direction. The electrical connector 1 is connected to a main printed circuit board 2 to achieve data transmission. Figure 1 As shown, preferably, the electrical connector 1 can be configured to be surface mounted on a main printed circuit board 2 .
[0058] like Figures 2 to 4As shown, the electrical connector 1 may include a housing 10 and a printed circuit board assembly 20. The housing 10 may have a housing cavity 11 for accommodating a mating electrical connector, the housing cavity 11 passes through the housing 10 in the insertion direction X, and the housing 10 may have a front side 12 for inserting a mating electrical connector and a back side 13 opposite to the front side 12. In some examples, the housing 10 may be molded from an insulating material such as plastic. The plastic may include, but is not limited to, liquid crystal polymers, high temperature nylon, polyphenylene oxide, or polypropylene, or other materials may be used for the plastic. In some examples, the plastic may be a thermosetting plastic. In some examples, the plastic may include, for example, a glass fiber reinforced insulating material. In some examples, the housing 10 may generally be a one-piece piece. In some examples, the housing 10 may be an injection molded part.
[0059] In some exemplary embodiments, the front side 12 of the housing 10 may have a shape corresponding to the shape of a mating electrical connector (eg, a plug). Figure 3 As shown, the tab receiving portion 121 of the front side 12 of the housing 10 for receiving the tab of the mating electrical connector (eg, plug) is located in the lateral direction Z of the electrical connector 1. In some examples, the plug may be, for example, a Cat5e, Cat6, or Cat6a plug.
[0060] In some exemplary embodiments, Figure 2 As shown, the PCB assembly 20 may be mounted in the housing 10 and connected to the back side 13 of the housing 10 .
[0061] like Figure 5 As shown, the printed circuit board assembly 20 may include a plurality of first terminals 21, a plurality of second terminals 22 and a printed circuit board 23. The plurality of first terminals 21 may be connected to the first surface 230 of the printed circuit board 23 facing the accommodating cavity 11. The plurality of second terminals 22 may be connected to the printed circuit board 23 and extend in the vertical direction Y, that is, the plurality of second terminals may be connected to the printed circuit board 23 and extend toward the main printed circuit board 2 located below the electrical connector 1 to be connected to the main printed circuit board 2, thereby realizing the transmission of data / information. In some examples, the plurality of first terminals and the plurality of second terminals may be made of a conductive material such as metal, such as copper, aluminum or tin. The first terminal and the second terminal may generally be formed as an integral piece, respectively.
[0062] In addition, if Figure 5As shown, the plurality of first terminals 21 may be arranged along the vertical direction Y, and each first terminal may be connected to a corresponding connection pad 2301 formed on the first side 230 of the printed circuit board 23. In some examples, the plurality of first terminals 21 may be arranged and aligned spaced apart from each other along the vertical direction Y, and each first terminal may be connected to a corresponding connection pad 2301 on the first side 230 of the printed circuit board 23. Preferably, in Figure 5 In the illustrated embodiment, the printed circuit board assembly 20 may include eight first terminals, which are arranged and aligned to be spaced apart from each other along the vertical direction Y, and each first terminal is respectively connected to a corresponding one of the eight connection pads 2301 on the first surface 230 of the printed circuit board 23. However, the embodiment is not limited thereto, and those skilled in the art will appreciate that the number of the first terminals may be determined according to the number of connection pads on the printed circuit board.
[0063] In addition, if Figure 5 As shown, each of the plurality of first terminals 21 can be formed by bending to include a first portion 210, a second portion 211, and a bent portion 212 connecting the first portion 210 and the second portion 211. The free end of the first portion 210 can be formed by bending to form a connecting portion 213 fixedly connected to a connecting pad 2301 of the first surface 230 of the printed circuit board 23. Preferably, the connecting portion 213 of the first portion 210 of the first terminal 21 is welded to the corresponding connecting pad 2301. By forming the connecting portion for welding to the printed circuit board by bending, the connection area between the first terminal 21 and the printed circuit board 23 is increased, thereby improving the stability of welding.
[0064] In some examples, the connection portion 213 of each of the plurality of first terminals can be connected to the printed circuit board 23 using surface mounting technology (SMT), thereby simplifying the design and assembly process of the printed circuit board. Surface mounting means that a component or contact portion is directly mounted on the surface of the printed circuit board.
[0065] Specifically, the connection portion 213 of each of the plurality of first terminals can be connected to the corresponding connection pad 2301 of the printed circuit board 23 by reflow soldering. Reflow soldering is an important soldering technology in the SMT process, and its principle is to solder surface mounted components to a printed circuit board. During the reflow soldering process, the printed circuit board is conveyed to a specified temperature area by a conveyor belt or hot air equipment, and the soldering material is melted by high temperature to form a mechanical connection and an electrical connection between the surface mounted component and the printed circuit board, thereby realizing a reliable circuit. The reflow soldering process forms solder joints by first preheating the component, printed circuit board or soldering material, and then melting the soldering material without causing damage due to overheating.
[0066] In some examples not shown, in the process of welding the bent first terminals to the printed circuit board, the first terminals are connected to a fixture for auxiliary welding, and with the help of the fixture, the connection parts of the first terminals are firmly welded to the printed circuit board. After welding, the fixture is removed from the first terminals and the first terminals are trimmed.
[0067] In an alternative embodiment, each of the plurality of first terminals may be inserted into a through hole formed in the printed circuit board and connected to the printed circuit board by reflow soldering.
[0068] like Figure 6 As shown, the lower side portion 231 of the printed circuit board 23 in the vertical direction Y may include a plurality of second terminal connection holes 232. The plurality of second terminal connection holes 232 may be arranged in rows so that each row includes the same number of second terminal connection holes, each row is parallel to each other along the transverse direction Z, and a row of second terminal connection holes in each row is arranged on the printed circuit board 23 in a manner that is staggered by the same distance from another row of second terminal connection holes in the transverse direction. Preferably, the plurality of second terminal connection holes 232 may include a first row of second terminal connection holes and a second row of second terminal connection holes that are arranged parallel to each other in the transverse direction Z, and the second terminal connection holes in the first row of second terminal connection holes and the second terminal connection holes in the second row of second terminal connection holes are arranged on the printed circuit board 23 in a manner that is staggered by the same distance from each other in the transverse direction Z. For example, in Figure 6 In the exemplary embodiment shown, the printed circuit board 23 includes 8 second terminal connection holes 232, which are arranged in two rows with 4 second terminal connection holes in each row, and the 4 second terminal connection holes in the first row and the 4 second terminal connection holes in the second row are staggered by the same distance in the transverse direction Z.
[0069] In some exemplary embodiments, the plurality of second terminals 22 may be disposed corresponding to the plurality of second terminal connection holes 232 and connected to the printed circuit board via the plurality of second terminal connection holes. Figure 5 In the embodiment shown, the four second terminals in the first row are respectively inserted into the four second terminal connection holes in the first row and connected to the printed circuit board, and the four second terminals in the second row are respectively inserted into the four second terminal connection holes in the second row and connected to the printed circuit board. However, the embodiment is not limited thereto, as long as the number of the second terminals and the number of the second terminal connection holes correspond to the number of the first terminals.
[0070] In some exemplary embodiments, Figure 6As shown, each of the plurality of second terminals 22 may include a mounting end portion 220 and a mating end portion 221, the mounting end portion 220 may be inserted into the second terminal connection hole 232, and the mating end portion 221 may extend along the vertical direction Y, that is, the mating end portion 221 may extend toward the main printed circuit board 2 and be connected to the main printed circuit board 2. Preferably, the mating end portions 221 may extend toward the main printed circuit board 2 and be connected to the main printed circuit board 2 in parallel with each other.
[0071] In some exemplary embodiments, Figure 6 As shown, each of the plurality of second terminals 22 may further include one or more bent portions 223 disposed between the mounting end portion 220 and the mating end portion 221. Figure 6 In the illustrated embodiment, each of the four second terminals in the first row includes three bends, and each of the four second terminals in the second row includes one bend, so that the mating ends of the four second terminals in the first row and the mating ends of the four terminals in the second row are staggered parallel to each other to form two rows. However, the embodiment is not limited thereto, and the second terminals in the first row and the second terminals in the second row may include other numbers of bends, as long as the bends of the second terminals in the first row and the second terminals in the second row are arranged so that the mating ends 221 of the second terminals both extend toward the main printed circuit board 2 to be connected to the main printed circuit board 2.
[0072] Normally, the printed circuit board of the electrical connector is located at the bottom of the electrical connector and the main printed circuit board is located below the electrical connector. When the electrical connector 1 needs to be installed in a configuration that is rotated 90 degrees relative to the main printed circuit board 2 located below the electrical connector 1, the printed circuit board of the electrical connector is located on the side of the electrical connector, so that the terminals connected to the printed circuit board of the electrical connector extend in the lateral direction (i.e., the transverse direction Z). At this time, connecting the printed circuit board of the electrical connector to the main printed circuit board located below the electrical connector requires the use of another wiring structure or the use of a board-to-board electrical connector, which inevitably leads to reduced signal reliability and increased connection costs. Through the electrical connector 1 provided by the present application, since the printed circuit board 23 of the electrical connector 1 is located at the back side 13 of the housing 10 and the second terminal 22 is directly connected to the main printed circuit board 2, the transmission speed of the electrical connector can be significantly improved, and the components required for connection are reduced, thereby reducing the connection cost. For example, the electrical connector of the present application enables users to achieve high-speed Ethernet connections of up to 1G per second, optionally 10G.
[0073] In some examples, the printed circuit board (conductor) 23 adopts a printed circuit board having multiple conductive layers. In some examples, the printed circuit board (conductor) 23 can adopt a printed circuit board having 4-6 conductive layers. A plurality of first terminals are connected to a plurality of second terminals in a one-to-one correspondence through a printed circuit board having multiple conductive layers, and each of the first terminals in the plurality of first terminals and each of the second terminals in the plurality of second terminals are connected through the printed circuit board. The respective connection parts are distributed in the respective layers of the printed circuit board, and the trace length (i.e., signal path length) of each connection part is equal, thereby providing capacitive compensation to achieve signal integrity and meet the requirements of Cat5e, Cat6 and Cat6a plugs. In some examples, the trace length of each connection part can be set in the printed circuit board software.
[0074] In some exemplary embodiments, Figure 6 As shown, the lower side portion 231 of the printed circuit board 23 may include a receiving portion 233 and a pair of fixing through holes 234.
