Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a power connector. Background Art

[0002] When a power connector is docked with a device, an electric arc will be generated. The high heat generated by the electric arc will damage the contacts, thereby affecting the normal operation of the power connector.

[0003] In order to reduce the generation of electric arcs, detection terminals are provided in some power connectors to ensure that the power supply is connected after the plug is inserted into the socket. However, how to ensure the normal operation of the power connector in a compact space has become a technical research direction in the industry.

In addition, although the first contact is lifted, since the first power terminal and the second power terminal are laminated together, the first power terminal can still jointly transmit power with the second power terminal.

[0062] The following description of the embodiments refers to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented. The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference 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.

[0063] Please refer to Figures 1 to 3 As shown, the power connector 1 of the present invention at least includes an insulating housing 10, a first power terminal 20 and a second power terminal 30. The insulating housing 10 has a docking section 11 and an installation section 12. A slot 13 is provided in the docking section 11 for an insert 9 (see Figure 4 ) to be inserted. The first power terminal 20 is installed in the insulating housing 10. The first power terminal 20 has a first fixing plate 21 located in the installation section 12 and at least one first elastic arm 22 located in the docking section 11. The first elastic arm 22 forms a first contact 220. The first contact 220 enters the slot 13. The second power terminal 30 is stacked on one side of the first power terminal 20 facing the slot 13 and is jointly installed in the insulating housing 10 with the first power terminal 20. The second power terminal 30 has a second fixing plate 31 stacked on the first fixing plate 21 and at least one second elastic arm 32 stacked on the first elastic arm 22. The second elastic arm 32 forms a second contact 320. The second contact 320 enters the slot 13. Among them, the first contact 220 and the second contact 320 are arranged adjacent to each other along the depth direction A1 of the slot 13.

[0064] Please refer to Figure 4 and Figure 5As shown, the first contact 220 is used to first make electrical contact with the insert 9, and the second contact 320 is used to make electrical contact with the insert 9 after the first contact 220 makes electrical contact with the insert 9 and to lift the first contact 220 away from the insert 9.

[0065] In the power connector 1 of the present invention, by laminating the first power terminal 20 and the second power terminal 30 together, the two power terminals can jointly transmit power. The first contact 220 and the second contact 320 are respectively arranged on the first power terminal 20 and the second power terminal 30 and are adjacent to each other along the depth direction A1 of the slot 13. Therefore, the first contact 220 can make electrical contact with the insert 9 first. At this time, an arc may be generated and damage the first contact 220. However, as the insert 9 continues to be inserted, the second contact 320 makes smooth electrical contact with the insert 9. At this time, since the first contact 220 has already made electrical contact with the insert 9, no arc phenomenon will occur when the second contact 320 makes electrical contact with the insert 9. At the same time, since the first contact 220 has been successfully lifted by the second contact 320, the damaged first contact 220 will not affect power transmission. In addition, although the first contact 220 is lifted, since the first power terminal 20 and the second power terminal 30 are laminated together, the first power terminal 20 can still jointly transmit power with the second power terminal 30.

[0066] It can be seen from this that the power connector 1 of the present invention protects the second contact 320 from arc damage by sacrificing the first contact 220, thereby ensuring that the second contact 320 can make normal contact with the insert 9 and ensuring that the power connector 1 can work properly.

[0067] Please refer to Figure 2 As shown, the first power terminal 20 has a plurality of first elastic arms 22 arranged in a row along the length direction A2 of the slot 13; and the second power terminal 30 has a plurality of second elastic arms 32 arranged in a row along the length direction A2 of the slot 13. Among them, both the first elastic arm 22 and the second elastic arm 32 are inclined towards the slot 13. Specifically, both the first elastic arm 22 and the second elastic arm 32 are inclined and extend into the slot 13, as Figure 3 shown.

[0068] Furthermore, as Figure 6As shown, the first elastic arm 22 has a first fixed end 221 and a first free end 222. From the first fixed end 221 to the first free end 222 of the first elastic arm 22, there are sequentially arranged a first inclined section 223, a first bending section 224, and a first protruding structure 225. Wherein the first protruding structure 225 protrudes towards the slot 13 (see Figure 3 ), and a first contact 220 is formed on the side of the first protruding structure 225 facing the slot 13.

[0069] Similarly, the second elastic arm 32 has a second fixed end 321 and a second free end 322. As Figure 6 shown, from the second fixed end 321 to the second free end 322 of the second elastic arm 32, there are sequentially arranged a second inclined section 323, a second bending section 324, and a second protruding structure 325. Wherein the second protruding structure 325 protrudes towards the slot 13 (see Figure 3 ), and a second contact 320 is formed on the side of the second protruding structure 325 facing the slot 13.

[0070] In the present invention, by laminating the first elastic arm 22 and the second elastic arm 32, and at the same time arranging the first contact 220 and the second contact 320 adjacent to each other along the depth direction A1 of the slot 13, it can be ensured that the second contact 320 successfully lifts the first contact 220 when electrically contacting the insert 9.

[0071] It should be noted that in this embodiment, the adjacent arrangement of the first contact 220 and the second contact 320 along the depth direction A1 of the slot 13 means that the straight line connecting the first contact 220 and the second contact 320 is parallel to the depth direction A1 of the slot 13. That is, along the depth direction A1 of the slot 13, the first contact 220 and the second contact 320 are arranged front and back.

[0072] Furthermore, the first contact 220 and the second contact 320 have the same height along the height direction A3 of the slot 13 (see Figure 3 ). When the second contact 320 makes electrical contact with the insert 9, the first contact 220 is successfully lifted through the displacement of the second contact 320.

[0073] Of course, in other embodiments, along the height direction A3 of the slot 13, the second contact 320 may be slightly lower than the first contact 220, that is, the second contact 320 may extend deeper into the slot 13 than the first contact 220. When the second contact 320 is in electrical contact with the insert 9, the second contact 320 will generate more displacement, thus successfully lifting the first contact 220.

[0074] As Figure 7 shown, the first inclined section 223 and the second inclined section 323 are stacked. The first bending angle 2240 of the first bending section 224 is greater than the second bending angle 3240 of the second bending section 324, and the second contact 320 is located on the side of the first inclined section 223 facing the slot 13. Thus, the first contact 220 and the second contact 320 can be arranged front and back, and the heights of the first contact 220 and the second contact 320 are the same along the height direction A3 of the slot 13.

[0075] In one embodiment, the power connector 1 can be mounted to a server rack (not shown), and the insert 9 can be a busbar. As Figure 4 shown, the insert 9 has a first conductive surface 91 and a second conductive surface 92 arranged opposite to each other, and when it is inserted into the power connector 1, it can supply power to the server rack.

[0076] More specifically, as Figure 2 、 Figure 4 shown, the slot 13 has opposite first side 130 and second side 131, corresponding to the first conductive surface 91 and the second conductive surface 92 of the insert 9 respectively. The first contact 220 and the second contact 320 enter the slot 13 from the first side 130 and are in electrical contact with the first conductive surface 91 of the insert 9 successively.

[0077] Please refer to Figures 2 to 5As shown, in one embodiment, the power connector 1 further includes a third power terminal 40 and a fourth power terminal 50. The third power terminal 40 and the fourth power terminal 50 are stacked, and are independent of the first power terminal 20 and the second power terminal 30 which are stacked. The third power terminal 40 has a third fixing plate 41 located at the mounting section 12 and at least one third elastic arm 42 located at the docking section 11; the third elastic arm 42 forms a third contact 420; the third contact 420 enters the slot 13 from the second side 131. The fourth power terminal 50 is stacked on the side of the third power terminal 40 facing the slot 13 and is jointly installed in the insulating housing 10 with the third power terminal 40; the fourth power terminal 50 has a fourth fixing plate 51 stacked on the third fixing plate 41 and at least one fourth elastic arm 52 stacked on the third elastic arm 42; the fourth elastic arm 52 forms a fourth contact 520; the fourth contact 520 enters the slot 13 from the second side 131. Wherein, the third contact 420 and the fourth contact 520 are arranged adjacent to each other along the depth direction A1 of the slot 13; the third contact 420 is used to first make electrical contact with the second conductive surface 92 of the insert 9, and the fourth contact 520 is used to make electrical contact with the second conductive surface 92 of the insert 9 after the third contact 420 makes electrical contact with the insert 9 and lift the third contact 420 off the insert 9.

[0078] It can be seen from this that the power connector 1 of the present invention protects the fourth contact 520 from arc damage by sacrificing the third contact 420, so as to ensure that the fourth contact 520 can make normal contact with the insert 9 and ensure that the power connector 1 can work properly.

[0079] More specifically, the first power terminal 20 and the third power terminal 40 have the same structure and are symmetrically arranged in the insulating housing 10; and the second power terminal 30 and the fourth power terminal 50 have the same structure and are symmetrically arranged in the insulating housing 10. For example: in this embodiment, along the height direction A3 of the slot 13, the heights of the third contact 420 and the fourth contact 520 are the same. In other embodiments, the heights of the third contact 420 and the fourth contact 520 may be slightly different. For example, the fourth contact 520 may extend deeper into the slot 13 than the third contact 420.

[0080] Please refer to Figure 6 and Figure 7As shown, the first power terminal 20 has a first connection section 23, which is located between the first fixing plate 21 and the first elastic arm 22 and is used to connect the first fixing plate 21 and the first elastic arm 22.

The second power terminal 30 has a second connection section 33 stacked on the first connection section 23 and is used to connect the second fixing plate 31 and the second elastic arm 32. The second power terminal 30 is generally Z-shaped. Among them, the second connection section 33 is stacked on the first connection section 23.

[0081] Similarly, the third power terminal 40 has a third connection section 43, which is located between the third fixing plate 41 and the third elastic arm 42. The third power terminal 40 is generally Z-shaped. The fourth power terminal 50 has a fourth connection section 53 stacked on the third connection section 43 and is located between the fourth fixing plate 51 and the fourth elastic arm 52. The fourth power terminal 50 is generally Z-shaped. Among them, the fourth connection section 53 is stacked on the third connection section 43.

[0082] Please refer to Figure 7 As shown, the first fixing plate 21, the second fixing plate 31, the third fixing plate 41, and the fourth fixing plate 51 are parallel to each other; a plate spacing D1 is formed between the second fixing plate 31 and the fourth fixing plate 51; a connection spacing D2 is formed between the second connection section 33 and the fourth connection section 53; among them, the plate spacing D1 is smaller than the connection spacing D2, so as to reserve installation space for the power cable. The connection spacing D2 mainly refers to the spacing between the middle positions of the second connection section 33 and the fourth connection section 53.

[0083] Please refer to Figure 6 As shown, the second elastic arm 32 has a second fixed end 321 and a second free end 322, and the second contact 320 is near the second free end 322; the fourth elastic arm 52 has a fourth fixed end 521 and a fourth free end 522, and the fourth contact 520 is near the fourth free end 522; a first spacing D3 is formed between the second fixed end 321 and the fourth fixed end 521 (see Figure 7 ); a second spacing D4 is formed between the second contact 320 and the fourth contact 520 (see Figure 7 ); among them, the second spacing D4 is smaller than the first spacing D3; among them, the first spacing D3 is larger than the plate spacing D1.

[0084] Please refer to Figure 8As shown, the first fixing plate 21 is fixedly connected to at least one first power cable 61 through a first welding plate 60; the first welding plate 60 is fixed to the side of the first fixing plate 21 facing away from the second fixing plate 31. The third fixing plate 41 is fixedly connected to at least one second power cable 63 through a second welding plate 62; the second welding plate 62 is fixed to the side of the third fixing plate 41 facing away from the fourth fixing plate 51.

[0085] Please refer to Figure 6 and Figure 7 As shown, the power connector 1 further includes a first reinforcing piece 70, which is laminated and fixed to the side of the first power terminal 20 facing away from the second power terminal 30; the first reinforcing piece 70 covers a part of the first elastic arm 22, the first connecting section 23, and a part of the first fixing plate 21. By means of screwing, the first reinforcing piece 70, the first power terminal 20, and the second power terminal 30 are fixedly connected together and installed in the insulating housing 10 together, and the first reinforcing piece 70 is used to enhance the structural strength of the first power terminal 20 and the second power terminal 30.

[0086] Similarly, the power connector 1 further includes a second reinforcing piece 71, which is laminated and fixed to the side of the third power terminal 40 facing away from the fourth power terminal 50; the second reinforcing piece 71 covers a part of the third elastic arm 42, the third connecting section 43, and a part of the third fixing plate 41. By means of screwing, the second reinforcing piece 71, the third power terminal 40, and the fourth power terminal 50 are fixedly connected together and installed in the insulating housing 10 together, and the second reinforcing piece 71 is used to enhance the structural strength of the third power terminal 40 and the fourth power terminal 50.

[0087] In summary, in the power connector 1 of the present invention, the first contact 220 and the third contact 420 are used to protect the second contact 320 and the fourth contact 520 respectively. Therefore, when the second contact 320 and the fourth contact 520 are in electrical contact with the first conductive surface 91 and the second conductive surface 92 of the insert 9, no electric arc will be generated, and thus they will not be damaged. The present invention also uses the second contact 320 and the fourth contact 520 to lift the first contact 220 and the third contact 420 away from the insert 9 respectively, preventing the damaged first contact 220 and third contact 420 from affecting power transmission. At the same time, although both the first contact 220 and the third contact 420 are lifted, since the first power terminal 20 and the second power terminal 30 are stacked together, and the third power terminal 40 and the fourth power terminal 50 are stacked together, the first power terminal 20 can still transmit power jointly with the second power terminal 30, and the third power terminal 40 can still transmit power jointly with the fourth power terminal 50.
