Description

Technical Field

[0001] The present invention relates to a connector, and more particularly to an electrical connection assembly. Background Art

[0002] Nowadays, the power density and efficiency requirements of power supply products are increasing. According to the specifications of the MCRPS (Modular Hardware System-Common Redundant Power Supply) platform, the wattage of a power supply unit with a 12V output voltage has increased to 3200W to 3600W. In other words, in high-wattage and high-current applications, the loss caused by the contact impedance of the electrical connection components cannot be ignored, which will not only cause a decrease in power density and efficiency, but may also cause safety issues due to temperature rise.

[0003] The existing electrical connection assembly usually includes a female connector and a male connector, wherein the female connector includes a plurality of terminals arranged symmetrically, and the male connector includes a contact portion, wherein the male connector is pluggable and connected to the female connector, so that the contact portion of the male connector is clamped and contacts between the plurality of terminals of the female connector, thereby realizing the electrical connection between the male connector and the female connector. However, each terminal of the existing female connector has only a single point of contact with the contact portion of the male connector, and its contact impedance is relatively high. In addition, the terminal of the female connector is usually made of copper material, and its temperature tolerance is relatively low. When the terminal of the female connector is electrically connected to the contact portion of the male connector in a single-point contact manner, the higher contact impedance will cause a temperature rise, which may cause the temperature of the terminal to rise to exceed the temperature tolerance of the material, which may cause safety problems. On the other hand, some existing electrical connection assemblies increase the contact area between the contact portion of the male connector and the plurality of terminals of the female connector by increasing the clamping force between the plurality of terminals of the female connector, thereby achieving the effect of reducing impedance. However, when the clamping force between the multiple terminals of the female connector is increased, the stress on the contact portion of the male connector will increase, which may cause problems such as structural damage or material fatigue.

[0004] In view of this, it is necessary to provide an improved electrical connection assembly to solve the problems faced by the prior art. Summary of the invention

[0005] The purpose of the present invention is to provide an electrical connection component, which includes a first connector and a second connector, wherein the contact portion of the first terminal of the first connector abuts against the groove of the corresponding second terminal of the second connector, so that when the first connector and the second connector are connected, the contact area between the terminals is increased, so as to reduce the contact impedance and reduce the loss, and can improve the power density and efficiency, and can avoid the temperature rise problem caused by excessively high contact impedance, and avoid the problems of structural damage or material fatigue caused by high stress.

[0006] To achieve the aforementioned purpose, the present case provides an electrical connection component, comprising a first connector and a second connector. The first connector comprises at least one first terminal. Each first terminal comprises at least one contact portion. The second connector is configured to be pluggable and docked with the first connector, and comprises at least one second terminal. Each second terminal comprises at least one groove. At least one groove is formed by being recessed inward from the surface of at least one second terminal. At least one groove comprises at least one connecting section and a bottom. At least one connecting section is connected between the bottom and the surface of the second terminal. At least one connecting section comprises a plurality of contact points. At least one contact portion of each first terminal of the first connector abuts against at least one groove of the corresponding second terminal of the second connector, and at least one contact portion forms multi-point contact with the bottom of at least one groove and a plurality of contact points.

[0066] Figure 1 is a schematic diagram of the structure of the electrical connection assembly of the first embodiment of the present invention, Figure 2 for Figure 1 A schematic cross-sectional structure diagram of a first connecting member and a second connecting member of an electrical connecting assembly, Figure 3 for Figure 1 A schematic cross-sectional structural diagram of a second connecting member of an electrical connecting assembly docking with a first connecting member, Figure 4 for Figure 3A schematic diagram of a partially enlarged cross-sectional structure of an electrical connection component in area A. Figures 1 to 4 As shown, the electrical connection assembly 100 of the first embodiment of the present case includes a first connector 1 and a second connector 2. The first connector 1 is an electrical connector and includes at least one first terminal 11, wherein each first terminal 11 includes at least one contact portion 111a. In this embodiment, the first connector 1 preferably includes a plurality of first terminals 11 and each first terminal 11 includes a contact portion 111a, but not limited thereto. Two first terminals 11 among the plurality of first terminals 11 are arranged opposite to each other, and a gap H is defined between the two first terminals 11. The second connector 2 is a Gold Finger connector and is configured to be pluggable and docked with the first connector 1. The second connector 2 includes at least one second terminal 21, wherein each second terminal 21 includes at least one groove 211. In this embodiment, the second connector 2 preferably includes a plurality of second terminals 21, and each second terminal 21 includes a groove 211, but not limited thereto. Two second terminals 21 among the plurality of second terminals 21 are arranged on two opposite sides of the second connector 2 and are arranged opposite to each other. In this embodiment, the groove 211 is formed by being recessed inward from the surface 210 of the second terminal 21. The groove 211 includes a bottom 212 and at least one connecting section 213. The at least one connecting section 213 is connected between the bottom 212 and the surface 210 of the second terminal 21. The at least one connecting section 213 includes at least one contact point 215. This embodiment is described by taking a plurality of contact points 215 as an example, but the number is not limited thereto. The bottom 212 and the plurality of contact points 215 allow the contact portion 111a of the first terminal 11 of the first connector 1 to contact and abut against each other. Figure 3 and Figure 4As shown, when the first connector 1 and the second connector 2 are docked and electrically connected, each contact portion 111a of the two first terminals 11 of the first connector 1 abuts against each groove 211 of the corresponding two second terminals 21 of the second connector 2, wherein each contact portion 111a forms a multi-point contact with the bottom 212 of the corresponding groove 211 and a plurality of contact points 215. By the bottom 212 of the groove 211 of the second terminal 21 of the second connector 2 and the plurality of contact points 215 abutting against the contact portion 111a of the corresponding first terminal 11 of the first connector 1, the terminal contact area between the first connector 1 and the second connector 2 is increased, so as to reduce the contact impedance to reduce the loss, and to improve the power density and efficiency, and to avoid the temperature rise problem caused by the excessively high contact impedance. In addition, by abutting the groove 211 of the second terminal 21 of the second connector 2 against the contact portion 111a of the corresponding first terminal 11 of the first connector 1, the terminal contact area between the first connector 1 and the second connector 2 can be increased without increasing the clamping force between the multiple first terminals 11 of the first connector 1, thereby avoiding problems such as structural damage or material fatigue caused by high stress.

[0067] like Figure 1 As shown, in this embodiment, the first connecting member 1 further includes a housing 10, wherein the housing 10 includes a containing space 10a and an opening 10b. A plurality of first terminals 11 are disposed in the containing space 10a of the housing 10, and a free end 112 of each first terminal 11 is adjacent to the opening 10b of the housing 10. The second connecting member 2 further includes a substrate 20, and the substrate 20 has two opposite first surfaces 20a and a second surface 20b. Two second terminals 21 of the plurality of second terminals 21 are disposed on the two opposite first surfaces 20a and the second surface 20b of the substrate 20, and are disposed opposite to each other. In this embodiment, the housing 10 has a first inner wall surface 101 and a second inner wall surface 102, wherein the first inner wall surface 101 and the second inner wall surface 102 are disposed opposite to each other. The housing 10 further has a plurality of first ribs 103 and a plurality of second ribs 104. The plurality of first ribs 103 are disposed on the first inner wall surface 101, and are arranged parallel to each other and spaced apart. A plurality of second ribs 104 are disposed on the second inner wall surface 102 and are arranged parallel to each other and spaced apart. A plurality of first ribs 103 define a plurality of first arrangement areas 105, and a plurality of second ribs 104 also define a plurality of second arrangement areas 106, wherein the first arrangement areas 105 and the second arrangement areas 106 are disposed opposite to each other. Each first arrangement area 105 and each second arrangement area 106 are respectively structured to arrange the first terminal 11.

[0068] like Figures 1 to 3As shown, in this embodiment, the two paired first terminals 11 of the first connector 1 are respectively disposed in the corresponding first arrangement area 105 and the second arrangement area 106, and are disposed symmetrically to each other. Each free end of the two first terminals 11 is a resilient cantilever structure, and a gap H is defined between the two first terminals 11. In this embodiment, each first terminal 11 includes a body section 110, a bending portion 111, and a free end 112, wherein the bending portion 111 is connected and disposed between the body section 110 and the free end 112, and a contact portion 111a is formed on the bending portion 111, wherein the bending portion 111 protrudes outward from the first terminal 11 toward the direction of the gap H, and the contact portion 111a is disposed on the side facing the gap H. The contact portion 111a may be, for example, but not limited to, an arc surface. In this embodiment, the two second terminals 21 of the second connector 2 are arranged on the two opposite first surfaces 20a and the second surface 20b of the substrate 20, and the two grooves 211 of the two second terminals 21 are respectively formed by being recessed inward from the surface 210, and the two grooves 211 are arranged opposite to each other. When the first connector 1 and the second connector 2 are docked and electrically connected, the substrate 20 of the second connector 2 is inserted into the gap H between the two first terminals 11 of the first connector 1, and the two first terminals 11 abut against the corresponding two second terminals 21 with their respective contact portions 111a, and each contact portion 111a of the two first terminals 11 abuts against each groove 211 of the corresponding two second terminals 21. By the grooves 211 of the second terminals 21 abutting against the contact portions 111a of the corresponding first terminals 11, the contact area between the terminals is increased, so as to reduce the contact impedance and reduce the loss, and the power density and efficiency can be improved, and the temperature rise problem caused by the excessively high contact impedance can be avoided, and the problems of structural damage or material fatigue caused by high stress can also be avoided.

[0069] In this embodiment, the contours of the two grooves 211 in the second connector 2 match the contour of the contact portion 111a of the first terminal 11, and the contact portion 111a of the first terminal 11 forms multi-point contact with multiple contact points 215 of the groove 211 of the second connector 2, thereby increasing the terminal contact area to reduce contact impedance and reduce loss.

[0070] In some embodiments, the groove 211 of the second terminal 21 of the second connector 2 is formed on the surface 210 of the second terminal 21 by metal layer etching, metal layer stacking, metal layer electroplating, metal layer of a printed circuit multilayer board, metal layer machining, etc., but is not limited to this.

[0071] like Figures 1 to 4As shown, in this embodiment, the bottom 212 of the groove 211 and at least one connecting section 213 together form a discontinuous arc surface profile structure. At least one connecting section 213 of the groove 211 includes at least one stepped structure 218. The stepped structure 218 is connected between the surface 210 of the second terminal 21 and the bottom 212 of the groove 211. A plurality of contact points 215 are formed on the at least one stepped structure 218. When the first connector 1 and the second connector 2 are docked and electrically connected, the contact portion 111a of the first terminal 11 of the first connector 1 abuts against the bottom 212 of the groove 211 and the plurality of contact points 215 of the stepped structure 218. By setting the stepped structure 218 and the bottom 212, the terminal contact area between the first connector 1 and the second connector 2 is increased to reduce the contact impedance and reduce the loss, and the power density and efficiency can be improved. The temperature rise problem caused by excessively high contact impedance can be avoided, and the structural damage or material fatigue caused by high stress can also be avoided. Figure 4 Each contact point 215 is shown as being in single-point contact with the contact portion 111a of the first terminal 11, but the contact method is not limited thereto. For example, when the contact portion 111a of the first terminal 11 abuts against each contact point 215, the contact point 215 is pressed by the contact portion 111a and deformed. In other words, the contact portion 111a and the contact point 215 may actually abut against each other in a surface contact manner, but the invention is not limited thereto.

[0072] In one embodiment, one end of the bottom 212 is connected to the surface 210 of the second terminal 21 through a stepped structure 218, and the other end of the bottom 212 is connected to the surface 210 of the second terminal 21 through another stepped structure 218, but the present invention is not limited thereto. By setting the two stepped structures 218 and the bottom 212, the terminal contact area between the first connector 1 and the second connector 2 is increased to reduce the contact impedance and reduce the loss, and the power density and efficiency can be improved, and the temperature rise problem caused by excessively high contact impedance can be avoided, and the problems of structural damage or material fatigue caused by high stress can also be avoided. In one embodiment, the stepped structure 218 is arranged around the bottom 212 and connected between the surface 210 and the bottom 212. In other words, the stepped structure 218 is a ring-shaped structure (not shown), which can increase the terminal contact area between the first connector 1 and the second connector 2 to reduce the contact impedance and reduce losses, and can improve power density and efficiency, and can avoid temperature rise problems caused by excessively high contact impedance, and can also avoid problems such as structural damage or material fatigue caused by high stress.

[0073] In this embodiment, the contact portion 111a of the first terminal 11 contacts the plurality of contact points 215 of each level 214 of the stepped structure 218 of the second terminal 21, so that the contact portion 111a and the stepped structure 218 form multi-point contact, thereby increasing the terminal contact area to reduce contact resistance and reduce loss. Figure 4 As shown, the stepped structure 218 includes at least one level 214. This embodiment is described by taking multiple levels 214 as an example, but is not limited thereto. In this embodiment, each level 214 of the stepped structure 218 includes a top surface 216 and a connecting surface 217. One end of the connecting surface 217 is connected to the top surface 216 or the surface 210, and the other end of the connecting surface 217 is connected to the top surface 216 or the bottom 212 of the adjacent level 214. Each contact point 215 is formed at the connection between the top surface 216 and the connecting surface 217 of each level 214. By setting the multiple contact points 215 of the stepped structure 218, the terminal contact area between the first connector 1 and the second connector 2 is increased to reduce the contact impedance and reduce the loss, and the power density and efficiency can be improved, and the temperature rise problem caused by the excessively high contact impedance can be avoided. In addition, the multiple levels 214 of the stepped structure 218 of this embodiment are simple in structure, easy to manufacture, and low in cost.

[0074] In other embodiments, the bottom 212 of the groove 211 and at least one connecting section 213 together form a continuous arc surface profile structure. In other words, the groove 211 is a continuous arc surface groove that is recessed inward from the surface 210 of the second terminal 21, wherein the continuous arc surface profile of the groove 211 of the second terminal 21 matches the arc surface of the contact portion 111a of the first terminal 11, thereby increasing the terminal contact area between the first connector 1 and the second connector 2, thereby reducing the contact impedance and reducing the loss, and can improve the power density and efficiency, and can avoid the temperature rise problem caused by excessively high contact impedance, and can also avoid the problems of structural damage or material fatigue caused by high stress.

The first terminal 11 includes a first contact portion 111b and a second contact portion 111c. The first contact portion 111b is disposed on the first bending section 111 and is disposed toward the gap H. The second contact portion 111c is disposed on the second bending portion 1112 and is disposed toward the gap H. The first groove 211a, the second groove 211b and the third groove 211c of the second terminal 21 are sequentially arranged and spaced apart from each other on the surface 210 of the second terminal 21.
