[0045] The following description of the embodiments refers to the accompanying drawings, which are used to illustrate specific embodiments in which the present invention can be implemented. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only references to the directions in the accompanying drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0046] The power connector of the present invention can be installed on a server rack. When an insert, such as a busbar, is inserted into the power connector, power can be supplied to the server rack.

[0047] Please refer to Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the power connector 1 includes an insulating housing 10, at least one power terminal 20, at least one conductive plate 30, and at least one signal cable fixing part 40.

[0048] As Figure 1 and Figure 2 shown, the insulating housing 10 has a slot 11 for inserting an insert 8. The power terminals 20 are arranged in the insulating housing 10. Please also refer to Figure 4 , Figure 5As shown, the power terminal 20 has at least one power contact portion 21 and at least one signal trigger portion 22. The power contact portion 21 protrudes into the slot 11 and is used to form electrical contact with the insert 8 first when the insert 8 is inserted into the slot 11. After the power contact portion 21 makes electrical contact with the insert 8, the signal trigger portion 22 is forced to displace away from the slot 11. The conductive plate 30 is disposed in the insulating housing 10. The conductive plate 30 is located on the side of the power terminal 20 opposite to the slot 11 and is independent of the power terminal 20. The conductive plate 30 makes electrical contact with the signal trigger portion 22 only after the power contact portion 21 makes electrical contact with the insert 8, and disconnects electrical contact with the signal trigger portion 22 after the insert 8 withdraws from the slot 11 and releases the power contact portion 21. The signal cable fixing member 40 is connected to the conductive plate 30 and is used to fix a signal cable 50. The signal cable 50 is connected to the conductive plate 30 and transmits a power supply signal when the conductive plate 30 makes electrical contact with the signal trigger portion 22.

[0049] Please refer to Figure 3 As shown, when the insert 8 is inserted into the slot 11, the insert 8 first makes contact with the power contact portion 21, then forces the power contact portion 21 to displace away from the slot 11. At the same time, the signal trigger portion 22 will follow the power contact portion 21 to displace away from the slot 11 until the signal trigger portion 22 touches the conductive plate 30. At this time, the power supply system of the power connector 1 will receive a power supply signal, and the power supply system supplies power to the insert 8. It can be seen that in the power connector 1 of the present invention, since the power terminal 20 has made electrical contact with the insert 8 before power supply, no arc will be generated between the power terminal 20 and the insert 8 at this time of power supply.

[0050] The power connector 1 of the present invention triggers the power supply signal by the contact between the power terminal 20 and the conductive plate 30. For example, the signal trigger portion 22 directly follows the displacement of the power contact portion 21 to trigger the power supply signal. Therefore, the triggering time of the power supply signal can be shortened, and the insert 8 can be powered in time.

[0051] The power connector 1 of the present invention directly uses the power terminal 20 and the conductive plate 30 as the signal trigger mechanism, without the need to additionally provide other structures as the signal trigger mechanism, thereby saving the space of the insulating housing 10 and making the structure of the power connector 1 more compact.

[0052] The following will specifically describe the structural details of the power connector 1 of one embodiment of the present invention.

[0053] Please refer to Figure 2 As shown, the insulating housing 10 has a docking side 12 and a mounting side 13, and the slot 11 is located on the docking side 12. The insulating housing 10 is further provided with at least one terminal receiving groove 14 that penetrates the docking side 12 and the mounting side 13, is located on one side (such as above or below) of the slot 11, and is used to receive the power terminal 20 and the conductive plate 30.

[0054] Please refer to Figure 4 、 Figure 5 As shown, in this embodiment, the power terminal 20 has a plurality of power contact portions 21 arranged in a row and a plurality of signal triggering portions 22 arranged in a row.

[0055] Specifically, the power terminal 20 has a plurality of elastic fingers 23 arranged in a row; each elastic finger 23 has a raised portion bent toward the slot 11 and a free end away from the slot 11 and close to the conductive plate 30. Among them, the raised portion serves as the power contact portion 21; the free end serves as the signal triggering portion 22. The power terminal 20 also has a power body portion 24 and a power cable connection portion 25; wherein, the plurality of elastic fingers 23 are evenly distributed and connected to the front end of the power body portion 24, and the power cable connection portion 25 is connected to the rear end of the power body portion 24 and is used for fixedly connecting with at least one power cable 60.

[0056] Specifically, the power terminal 20 is formed by two perpendicular bends and is generally in a Z shape; the power cable connection portion 25 is fixedly connected to the power cable 60 through a welding plate 70; the welding plate 70 is fixed to the side of the power cable connection portion 25 facing the conductive plate 30. In addition, a plurality of fixing structures 250 are formed on both side edges of the power cable connection portion 25 to clamp the power terminal 20 in the terminal receiving groove 14.

[0057] Please refer to Figure 4 、 Figure 5 As shown, the conductive plate 30 is a flat plate; a plurality of fins 31 are formed on both side edges of the flat plate to clamp the conductive plate 30 in the terminal receiving groove 14. The conductive plate 30 and the power terminal 20 are arranged in parallel in the terminal receiving groove 14 along the thickness direction T of the slot 11 (the label is shown in Figure 2 ), and a gap G (the label is shown in Figure 3)。In other words, there are gaps formed between the conductive plate 30 and the power supply contact portion 21, the signal trigger portion 22, and the power supply body portion 24. Therefore, the statement "the conductive plate 30 is independent of the power supply terminal 20" mentioned in this text means that before the insert 8, no connection or contact is formed between the conductive plate 30 and the power supply terminal 20.

[0058] In this embodiment, the positive projections of the elastic fingers 23 of the power supply terminal 20 on the conductive plate 30 all fall within the conductive plate 30. That is, the positive projections of the power supply contact portion 21 and the signal trigger portion 22 of the power supply terminal 20 on the conductive plate 30 all fall within the conductive plate 30, so as to ensure that the signal trigger portion 22 can accurately touch the conductive plate 30.

[0059] In addition, as Figure 6 shown, the conductive plate 30 has a conductive connecting piece 32, which is arranged on an installation edge 33 of the installation side 13 of the conductive plate 30 facing the insulating housing 10, especially can be arranged at the middle position of the installation edge 33, and of course can also be arranged at other positions of the installation edge 33. By arranging the conductive connecting piece 32 on the installation edge 33, the width of the conductive plate 30 does not need to be increased, so that the space of the insulating housing 10 in the width direction W (the label is shown in Figure 2 ) can be saved, and thus a power connector 1 with a narrower size can be provided.

[0060] Furthermore, as Figure 6 shown, the conductive connecting piece 32 is bent into an L shape, having a vertical section 320 and a horizontal section 321. The vertical section 320 extends towards the side facing away from the power supply terminal 20, and the horizontal section 321 extends towards the installation side 13 of the insulating housing 10.

[0061] Please refer to Figure 6 shown. The signal cable fixing member 40 has a first end portion 41 and a second end portion 42 which are oppositely arranged. The first end portion 41 is connected to the conductive connecting piece 32, for example, connected to the horizontal section 321 of the conductive connecting piece 32; the second end portion 42 is connected to the signal cable 50. Specifically, the first end portion 41 is a frame body, which can be used to position the signal cable fixing member 40 in the insulating housing 10; the second end portion 42 is a sheet body, which can wrap the outer skin of the signal cable 50. The central wire of the signal cable 50 is welded to the signal cable fixing member 40 or the conductive connecting piece 32. That is to say, the signal cable 50 can be indirectly electrically connected to the conductive plate 30 by welding to the signal cable fixing member 40, or can be directly electrically connected to the conductive plate 30 by welding to the conductive plate 30.

[0062] Please refer to Figure 6 As shown, the signal cable fixing member 40 and the conductive plate 30 are in two-piece form, and the signal cable fixing member 40 is welded to the conductive plate 30. In other embodiments, the signal cable fixing member 40 and the conductive plate 30 can also be directly formed in one-piece form by a stamping process.

[0063] In this embodiment, as Figure 4 and Figure 5 shown, the power connector 1 of the present invention includes at least a pair of power terminals, at least a pair of conductive plates, and at least a pair of signal cable fixing members.

[0064] As Figure 4 , Figure 5 shown, the pair of power terminals includes two power terminals 20 as described above, which can be respectively referred to as the first power terminal and the second power terminal. During installation, the first power terminal and the second power terminal have the same structure and are symmetrically arranged in the insulating housing 10 and on opposite sides of the slot 11 (for example Figure 1 shown, above the slot 11 and below the slot 11) to make electrical contact with two opposite insertion surfaces 80 of the insert 8. Each power terminal 20 has a plurality of power contact portions 21 arranged in a row and a plurality of signal trigger portions 22 arranged in a row. Each power contact portion 21 protrudes into the slot 11 to make electrical contact with the insert 8; each signal trigger portion 22 is forced to displace away from the slot 11 after the power contact portion 21 of the corresponding power terminal 20 makes electrical contact with the insert 8.

[0065] As Figure 4 , Figure 5 shown, the pair of conductive plates includes two conductive plates 30 as described above, which can be respectively referred to as the first conductive plate and the second conductive plate. During installation, the first conductive plate and the second conductive plate have the same structure and are symmetrically arranged in the insulating housing 10. Each conductive plate 30 corresponds to one of the power terminals 20 and is independent of the corresponding power terminal 20. Each conductive plate 30 is arranged on a displacement path of the signal trigger portion 22 of the corresponding power terminal 20, and makes electrical contact with the signal trigger portion 22 of the corresponding power terminal 20 only after the power contact portion 21 of the corresponding power terminal 20 makes electrical contact with the insert 8, and disconnects electrical contact with the signal trigger portion 22 after the insert 8 withdraws from the slot 11 and releases the power contact portion 21.

[0066] More specifically, the first conductive plate corresponds to the first power supply terminal and is independent of the first power supply terminal. The second conductive plate corresponds to the second power supply terminal and is independent of the second power supply terminal.

[0067] As Figure 4 shown, the pair of signal cable fixing members 40 includes two signal cable fixing members 40 as described above, which can be respectively referred to as the first signal cable fixing member and the second signal cable fixing member. Each signal cable fixing member 40 is connected to the corresponding conductive plate 30 and is also connected to the corresponding signal cable 50. Specifically, the first signal cable fixing member and the second signal cable fixing member are respectively connected to the first conductive plate and the second conductive plate, and are respectively used to fix two signal cables 50. The two signal cables 50 are respectively connected to the first conductive plate and the second conductive plate to transmit power supply signals.

[0068] As Figure 3 shown, among the pair of power supply terminals 20, the power contact portion 21 is used to jointly clamp the insert 8, and the distance D1 between the power cable connection portions 25 is smaller than the distance D2 between the power supply body portions 24.

[0069] In summary, for the power connector 1 of the present invention, since the power supply terminal 20 has been in electrical contact with the insert 8 before power supply, no arc will be generated between the power supply terminal 20 and the insert 8 during power supply. In addition, since the power connector 1 of the present invention directly triggers the power supply signal by the contact between the power supply terminal 20 and the conductive plate 30, the triggering time of the power supply signal can be shortened, and the insert 8 can be powered in time. The power connector 1 of the present invention also saves space because no additional signal triggering mechanism is required, thereby making the structure more compact.
