[0034] Electrical connectors are typically used at the power output end. They are interface components that transmit electrical energy from power modules (such as uninterruptible power supplies, battery packs, and power distribution cabinets) to downstream devices. They are often used to distribute main power to server racks.
[0035] Existing electrical connectors have poor heat dissipation performance, which affects their overall performance.
[0036] This invention proposes an electrical connector designed to improve its heat dissipation performance.
[0037] Please see Figures 1 to 4In one embodiment of this utility model, the electrical connector 100 includes a housing 1, two end sub-modules 2, two conductive modules 3, and two flexible connecting elements 4. The housing 1 includes a body 12 and a protrusion 11. The body 12 has a receiving cavity. The protrusion 11 is connected to a surface of the body 12 and has a slot 111. One end of the slot 111 communicates with the receiving cavity. The two end sub-modules 2 pass through the protrusion 11 and are exposed in the slot of the slot 111. The two conductive modules 3 are disposed in the receiving cavity. One conductive module 3 is connected to the surface of one terminal module 2 away from the other terminal module 2. Each conductive module 3 includes two sub-conductive blocks 31. A heat dissipation gap is formed between the two sub-conductive blocks 31. The extension direction of the heat dissipation gap is the length direction of the terminal module 2. One end of each flexible connecting element 4 is disposed in the receiving cavity and connected to the surface of the two sub-conductive blocks 31 away from the terminal module 2. The other end of each flexible connecting element 4 is used to connect to a power source.
[0038] In this embodiment, the outer shell 1 and the two end sub-modules 2 are made of commercially available materials, and no further limitations are made here. The flexible connecting element 4 refers to a flexible metal busbar made of copper fiber bundles, such as a soft copper busbar, or a cable bundle including multiple cables. The outer shell 1 includes a body 12 and a protrusion 11. The body 12 forms a receiving cavity for housing at least a portion of the two end sub-modules 2, two conductive modules 3, and two flexible connecting elements 4. The protrusion 11 is disposed on one surface of the body 12 and has a slot 111 communicating with the receiving cavity. A terminal module 2 is inserted into the slot 111. The protrusion 11 is used to insert into a server rack, so that the terminal module 2 is electrically connected to the rack busbar. In a preferred embodiment, the protrusion 11 is integrally formed with the body 12, improving the overall connection strength of the outer shell 1. The terminal module 2, conductive module 3, and flexible connecting element 4 located on the same side are connected together by bolts or screws, etc. Each conductive module 3 includes two sub-conductive blocks 31. The sub-conductive blocks 31 are arranged in the length direction of the terminal module 2. Therefore, the heat dissipation gap formed between the two sub-conductive blocks 31 is also arranged along the length direction of the terminal module 2, making the heat dissipation gap longer. Correspondingly, the heat dissipation area is larger, and the heat dissipation performance of the electrical connector 100 is better. It can be understood that, in another embodiment, the two sub-conductive blocks 31 are arranged in the width direction of the terminal module 2, and the heat dissipation gap formed between the two sub-conductive blocks 31 is also arranged along the width direction of the terminal module 2. The direction from one end of the terminal module 2 exposed in the slot 111 to one end disposed in the body 12 of the outer shell 1 is the length direction of the terminal module 2, and the direction relative to the thickness direction of the outer shell 1 is... Figure 3 The left and right directions are the same, which is the width direction of terminal module 2.
[0039] The technical solution of this utility model adopts a conductive module 3 including two separately arranged sub-conductive blocks 31, with a heat dissipation gap formed between the two sub-conductive blocks 31. The extension direction of the heat dissipation gap is the same as the length direction of the terminal module 2. Air can flow between the two sub-conductive blocks 31 through the heat dissipation gap, carrying away the heat generated by the two sub-conductive blocks 31 and other parts of the electrical connector 100, thereby improving the heat dissipation performance of the electrical connector 100.
[0040] In an embodiment of this utility model, a first heat sink group 32 is provided between the two sub-conductive blocks 31;
[0041] And / or, a second heat sink group 33 is provided on the surface of one sub-conductive block 31 facing away from the other sub-conductive block 31;
[0042] And / or, the flexible connecting element 4 has a third heat sink group 5 on the surface away from the conductive module 3.
[0043] In this embodiment, in order to further improve the heat dissipation performance of the electrical connector 100, a first heat sink group 32 is provided between the two sub-conductive blocks 31, that is, the first heat sink group 32 is provided in the heat dissipation gap. The first heat sink group 32 is made of aluminum with high specific heat capacity or copper with high thermal conductivity. The first heat sink group 32 includes multiple spaced fins to increase the surface area of the first heat sink group 32, improve heat dissipation efficiency, and thus improve the heat dissipation performance of the electrical connector 100.
[0044] In one example, a second heat sink assembly 33 is provided on the outer surface of the two sub-conductive blocks 31. That is, the surface of each sub-conductive block 31 facing away from the other sub-conductive block 31 is provided with a second heat sink assembly 33. The second heat sink assembly 33 is made of aluminum with high specific heat capacity or copper with high thermal conductivity. The second heat sink assembly 33 includes multiple spaced fins to increase the surface area of the second heat sink assembly 33, improve heat dissipation efficiency, and thus improve the heat dissipation performance of the electrical connector 100. It can be understood that the two second heat sink assemblies 33, the two sub-conductive blocks 31, and the first heat sink assembly 32 located on the same side are connected as a whole by bolts or screws.
[0045] To further improve the heat dissipation performance of the electrical connector 100, a third heat sink group 5 is provided on the surface of the flexible connecting element 4 facing away from the conductive module 3. The third heat sink group 5 is made of aluminum with high specific heat capacity or copper with high thermal conductivity. The third heat sink group 5 includes multiple spaced fins to increase the surface area of the third heat sink group 5, improve heat dissipation efficiency, and thus improve the heat dissipation performance of the electrical connector 100. It can be understood that the terminal module 2, conductive module 3, one end of the flexible connecting element 4, and the third heat sink group 5, located on the same side, are connected as a whole by screws or bolts.
[0046] The stacking direction of terminal module 2, sub-conductive block 31, flexible connecting element 4, and third heat sink group 5 is the width direction of the outer shell 1.
[0047] In an embodiment of this utility model, the two sub-conductive blocks 31 are integrally formed with the first heat sink assembly 32;
[0048] And / or, the sub-conductive block 31 and the second heat sink assembly 33 are integrally formed.
[0049] In this embodiment, each sub-conductive block 31 is processed to form a first heat sink group 32 on the surface facing another sub-conductive block 31, so that the sub-conductive block 31 and the first heat sink group 32 are integrally formed without connection, thereby improving the overall structural strength; each sub-conductive block 31 can also be processed to form a second heat sink group 33 on the surface facing away from another sub-conductive block 31, so that the sub-conductive block 31 and the second heat sink group 33 are integrally formed without connection with additional connectors, thereby improving the overall structural strength.
[0050] In an embodiment of this utility model, a gap is formed between the first heat sink group 32 and the sub-conductive block 31;
[0051] Alternatively, the first heat sink assembly 32 is connected to the surface of one sub-conductive block 31 facing another sub-conductive block 31.
[0052] In this embodiment, a gap is formed between the first heat sink assembly 32 and the sub-conductive block 31, allowing air to flow through the gap. While the first heat sink assembly 32 actively dissipates heat, the airflow within the gap also carries away heat from the first heat sink assembly 32, improving the heat dissipation effect. It is understood that in another embodiment, the surfaces of the first heat sink assembly 32 and the sub-conductive block 31 are directly connected, eliminating the need for additional connectors and improving the overall structural strength.
[0053] In an embodiment of this utility model, the body 12 of the outer shell 1 has a side opening 121, and the third heat sink group 5 is exposed in the side opening 121.
[0054] In this embodiment, the body 12 of the housing 1 has a side opening 121 so that the third heat sink group 5 can be exposed outside the housing 1 through the side opening 121, so that the heat of the third heat sink group 5 can be dissipated through the side opening 121, thereby improving the heat dissipation performance of the electrical connector 100.
[0055] In the embodiments of this utility model, the thickness of the outer shell 1 is greater than or equal to 32 mm and less than or equal to 40 mm;
[0056] The outer casing 1 has several heat dissipation holes that communicate with the receiving cavity.
[0057] In this embodiment, as Figure 3 As shown, Figure 3 The left and right directions in the figure represent the thickness direction of the outer shell 1. The thickness of the outer shell 1 is greater than or equal to 32mm and less than or equal to 40mm, such as 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm or any value within the above range. The thickness of the outer shell 1 should not be too small, otherwise the width of the terminal module 2 and the conductive module 3 will be too small to carry a large current. The thickness of the outer shell 1 should also not be too large, otherwise the overall size of the electrical connector 100 will not be able to be inserted into the server rack.
[0058] In one example, the housing 1 has multiple heat dissipation holes, which are evenly distributed at intervals on the housing 1, so that the heat generated by the terminal module 2, conductive module 3 and flexible connecting element 4 inside the housing 1 can be dissipated to the outside of the housing 1 through the heat dissipation holes, thereby improving the heat dissipation performance of the electrical connector 100.
[0059] In an embodiment of this utility model, the electrical connector 100 further includes a grounding terminal 6. The grounding terminal 6 includes an integrally formed base 61 and a terminal portion 62. The base 61 is embedded on a surface of the body 12, and the terminal portion 62 is embedded on the outer wall of the protrusion away from the slot 111. The base 61 has several through holes, one of which is connected to a heat dissipation hole. The grounding terminal 6 is used for grounding connection.
[0060] A vent hole 112 is provided on the end face of the protrusion away from the body 12, and the vent hole 112 is connected to the slot 111 and the receiving cavity.
[0061] In this embodiment, a terminal portion 62 of a grounding terminal 6 is embedded on the outer wall of the protrusion away from the slot 111. The grounding terminal 6 also includes a base 61 integrally formed with the terminal portion 62. The base 61 is embedded on a surface of the body 12 and has multiple through holes. One through hole communicates with a heat dissipation hole on the body 12 to allow air to circulate. The grounding terminal 6 is used for grounding connection to prevent damage to the electrical connector 100, prevent fire and lightning strikes, prevent electrostatic damage, and ensure the normal operation of the power system.
[0062] A vent hole 112 is provided at the end of the protrusion away from the body 12. The vent hole 112 is connected to the receiving cavity through the slot 111, so that the heat generated by the terminal module 2, conductive module 3 and flexible connecting element 4 in the receiving cavity can be discharged from the housing 1 through the slot 111 and finally through the heat dissipation hole, thereby improving the heat dissipation performance of the electrical connector 100.
[0063] In the embodiments of this utility model, the number of terminal portions 62 of the grounding terminal 6 is multiple, and the multiple terminal portions 62 are spaced apart and embedded in the outer wall of the protrusion away from the slot 111.
[0064] There are also multiple vent holes 112, with one vent hole 112 located between the two end portions 62.
[0065] In this embodiment, multiple terminal portions 62 are spaced apart and embedded on the outer wall of the protrusion away from the slot 111, further preventing damage to the electrical connector 100, preventing fire and lightning strikes, preventing electrostatic damage, and ensuring the normal operation of the power system.
[0066] Correspondingly, there are multiple vent holes 112. One vent hole 112 is located between two terminal portions 62. The vent hole 112 is connected to the receiving cavity through the slot 111, so that the heat generated by the terminal module 2, conductive module 3 and flexible connecting element 4 in the receiving cavity can be discharged from the housing 1 through the slot 111 and finally through multiple heat dissipation holes, further improving the heat dissipation performance of the electrical connector 100.
[0067] In an embodiment of this utility model, the other end of the flexible connecting element 4 away from the sub-conductive block 31 branches to form two sub-flexible connecting elements 41, and the welding surfaces of the two sub-flexible connecting elements 41 are perpendicular to each other.
[0068] In this embodiment, the other end of the flexible connecting element 4 branches to form two sub-flexible connecting elements 41. The welding surfaces of the two sub-flexible connecting elements 41 located on the same side are perpendicular to each other. The two sub-flexible connecting elements 41 located on both sides with their welding surfaces perpendicular to each other are connected to a connector for electrical connection with an external power source.
[0069] This utility model also proposes an electrical connector 100, including a housing 1, two end sub-modules 2, two conductive modules 3, and two flexible connecting elements 4.
