Description

Technical Field

[0001] The present invention relates to a connector and a connector assembly, in particular to a connector suitable for transmitting large currents. Prior Art

[0002] As the energy consumption of existing servers increases, the connectors used in existing servers need to transmit increasingly larger currents. Therefore, how to improve the current carrying capacity of existing connectors has become an important issue. Summary of the Invention

[0003] The present invention discloses a connector, which is mainly used to improve the current carrying capacity of existing connectors used in servers.

[0004] One embodiment of the present invention discloses a connector comprising an insulating body and at least one terminal set. The insulating body includes a terminal receiving slot; each terminal set includes two mating conductive plates, each having a plurality of elastic arms at one end, the plurality of elastic arms being positioned within the terminal receiving slot. The plurality of elastic arms of the two mating conductive plates in a terminal set are disposed facing each other, and each elastic arm has a protrusion and a notch at a free end, with each protrusion disposed facing the notch of the other elastic arm.

[0005] In summary, the connector of the present invention increases the elastic deformation space and deformation amount of the two mating conductive sheets by arranging the protrusions of the elastic arms of the two mating conductive sheets of each terminal group to face the notches, so that each mating conductive sheet can provide a greater positive force, thereby effectively improving the current carrying capacity of the connector.

[0023] In the following description, if it is indicated to refer to a specific figure or as shown in a specific figure, it is only used to emphasize that most of the relevant content described in the subsequent description appears in the specific figure, but it does not limit the subsequent description to only referring to the specific figure.

[0024] Please refer to Figures 1 to 5 together. Figure 1 is a schematic diagram of the mutual insertion of the connector components of the present invention. Figures 2 and 3 are schematic diagrams of the connector components of the present invention separated from each other from different perspectives. Figure 4 is a schematic diagram of the first embodiment of the connector of the present invention from another perspective. Figure 5 is a partially exploded schematic diagram of the first embodiment of the connector of the present invention.

[0025] The connector assembly A includes a connector 100 and a docking connector 300. The connector 100 and the docking connector 300 can be plugged into each other. The connector assembly A can be used in a server, for example, and can be used to transmit high current power.

[0026] Connector 100 is a wire-end connector comprising an insulating body 1 and two sets of connecting terminals 200. The insulating body 1 contains at least one terminal receptacle 12, each of which presents a plug-in interface 11 at the mating end of the insulating body 1. The plug-in interface 11 is rectangular. The multiple plug-in interfaces 11 within the terminal receptacles 12 are arranged in a row with their long sides facing each other, forming a mating interface. In this embodiment, at least one heat dissipation slot 17 is located between adjacent plug-in interfaces 11. A guide post 18 is located on each side of the mating interface to guide the mating connector 300 during mating. The guide posts are composed of multiple sheet-like structures and have a generally arc-shaped appearance.

[0027] Please refer to Figures 5 to 10 together. Figure 5 is a partially exploded schematic diagram of the first embodiment of the connector of the present invention. Figure 6 is a cross-sectional schematic diagram along the section line VI-VI of Figure 2. Figure 7 is a cross-sectional schematic diagram along the section line VII-VII of Figure 2. Figure 8 is a rear view of the first embodiment of the connector of the present invention. Figure 9 is a cross-sectional schematic diagram along the section line IX-IX of Figure 4. Figure 10 is a cross-sectional schematic diagram along the section line XX of Figure 2.

[0028] Each connection terminal assembly 200 includes two conductive components and two cables. The two conductive components are a first conductive component 2 and a second conductive component 3. The two cables are a first cable 4 and a second cable 5. The first conductive component 2 is electrically connected to the first cable 4, with at least a portion of the first conductive component 2 disposed within the insulating body 1. The second conductive component 3 is electrically connected to the second cable 5, with at least a portion of the second conductive component 3 disposed within the insulating body 1. A portion of the first conductive component 2 and a portion of the second conductive component 3 of each connection terminal assembly 200 are located within the same terminal receptacle 12.

[0029] As shown in Figures 5 to 7, the first conductive member 2 may include a first conductive sheet 21. The first conductive sheet 21 has a sheet-like structure. The first conductive sheet 21 includes a first contact portion 211, a first bent portion 212, and a first connecting portion 213. The ends of the first bent portion 212 are connected to the first contact portion 211 and the first connecting portion 213, respectively. The first contact portion 211, the first bent portion 212, and the first connecting portion 213 are integrally formed. In practical applications, the first conductive member 2 may be formed, for example, by stamping the first contact portion 211, the first bent portion 212, and the first connecting portion 213 in one piece.

[0030] The second conductive member 3 may include a second conductive sheet 31. The second conductive sheet 31 has a sheet-like structure. The second conductive sheet 31 includes a second contact portion 311, a second bent portion 312, and a second connecting portion 313. The ends of the second bent portion 312 are connected to the second contact portion 311 and the second connecting portion 313, respectively. The detailed description of the second contact portion 311, the second bent portion 312, and the second connecting portion 313 is the same as that of the first contact portion 211, the first bent portion 212, and the first connecting portion 213 described above and will not be repeated here.

[0031] The first contact portion 211 and the second contact portion 311 of each connecting terminal set are disposed in the same terminal receptacle 12 of the insulating body 1. The first connecting portion 213 and the second connecting portion 313 are respectively used to electrically connect to the first cable 4 and the second cable 5. The first cable 4 and the second cable 5 are offset from each other in the vertical direction (Z axis). In other words, the connection area between the first connecting portion 213 and the first cable 4 is offset from the connection area between the second connecting portion 313 and the second cable 5. The first curved portion 212 is offset to one side relative to the first contact portion 211, so that the first contact portion 211 and the first connecting portion 213 are located on two substantially parallel planes. The second curved portion 312 is offset to one side relative to the second contact portion 311, so that the second contact portion 311 and the second connecting portion 313 are located on two substantially parallel planes.

[0032] As shown in Figure 7, when the first conductive member 2 and the second conductive member 3 included in the same connecting terminal assembly 200 are fixedly mounted on the insulating body 1, the first contact portion 211 and the second contact portion 311 are located in the same terminal receptacle 12 and face each other (on the X-axis). The first bent portion 212 and the second bent portion 312 are also disposed opposite each other, and the first connecting portion 213 and the second connecting portion 313 are also disposed opposite each other. Furthermore, the distance H1 between the first contact portion 211 and the second contact portion 311 is smaller than the distance H2 between the first connecting portion 213 and the second connecting portion 313. The distance H3 between the first bent portion 212 and the second bent portion 312 gradually increases from the end closest to the first contact portion 211 to the end closest to the first connecting portion 213. The first contact portion 211 and the second contact portion 311 included in the same connecting terminal assembly 200 are designed to contact a mating terminal assembly 8 of the mating connector 300. The spacing between the first connecting portion 213 and the second connecting portion 313 is designed to accommodate a first conductive connector 41 at one end of the first cable 4 and a second conductive connector 51 at one end of the second cable 5. The first conductive connector 41 and the second conductive connector 51 are fixedly connected to the inner surfaces of the first connecting portion 213 and the second connecting portion 313, respectively, for example, by welding or ultrasonic bonding.

[0033] As shown in Figures 6 and 8 , by staggering the first conductive connector 41 and the second conductive connector 51 adjacent to the upper edge 1A and lower edge 1B of the insulating body 1, respectively, the first and second cables 4 and 5 connected to the first and second conductive members 2 and 3 are positioned approximately diagonally opposite each other, increasing the spacing between the first and second cables 4 and 5, thereby creating a larger heat dissipation gap S between the first and second cables 4 and 5. Consequently, when the first conductive member 2, the first cable 4, the second conductive member 3, and the second cable 5 transmit high currents, generating a large amount of heat, the heat can be more effectively dissipated through the larger heat dissipation gap S.

[0034] It should be noted that the connector 100 of the present invention improves the heat dissipation problem of the two cables when the connector 100 is transmitting high current without changing the existing size of the connector 100.

[0035] Please refer to Figures 4, 5, 9, and 10. Figure 9 is a schematic cross-sectional view taken along line IX-IX in Figure 4, and Figure 10 is a schematic cross-sectional view taken along line XX in Figure 2. As shown in Figures 2, 5, and 9, in actual applications, the first conductive member 2 may further include a first elastic engaging arm 214. One end of the first elastic engaging arm 214 may be connected to the first contact portion 211; the other end of the first elastic engaging arm 214 is a free end and may include a first engaging protrusion 2141. In this embodiment, the first elastic engaging arm 214 and the first curved portion 212 are connected to the upper and lower sides of one end of the first contact portion 211, respectively.

[0036] During the process of securing the first conductive member 2 to the insulating body 1, the first elastic engaging arm 214 may be elastically deformed. When the first conductive member 2 is secured to the insulating body 1, the first engaging protrusion 2141 may be correspondingly engaged with a first engaging hole 13 of the insulating body 1. The first engaging hole 13 is a through-hole extending through the insulating body 1 and is in communication with the terminal receiving groove 12.

[0037] Through the design of the first engaging protrusion 2141 and the first engaging hole 13, when the first conductive member 2 is fixedly arranged on the insulating body 1, relevant personnel can insert relevant tools (such as a flat-blade screwdriver) into the first engaging hole 13 to push the first elastic engaging arm 214, causing the first elastic engaging arm 214 to elastically deform in a direction close to the first connecting portion 213. Thereby, the first engaging protrusion 2141 will no longer be engaged with the first engaging hole 13, thereby relevant personnel can pull the first conductive member 2 and the first cable 4 out of the insulating body 1.

[0038] Additionally, the first conductive member 2 may include a first auxiliary positioning portion 215. The first auxiliary positioning portion 215 may be a protruding structure extending outward from a side edge of the first contact portion 211 adjacent to the first curved portion 212. The first auxiliary positioning portion 215 and the first elastic engaging arm 214 may, for example, be located on opposite sides of the first conductive member 2. As shown in FIG9 , when the first conductive member 2 is fixedly disposed in the insulating body 1, the first auxiliary positioning portion 215 abuts against a first body positioning portion 15 (e.g., a groove) within the insulating body 1. The first auxiliary positioning portion 215 and the first body positioning portion 15 jointly limit the range of motion of the first conductive member 2 relative to the insulating body 1 in the Y-axis direction shown in the figure.

[0039] In addition, through the design of the first auxiliary positioning portion 215 and the first main body positioning portion 15, when the relevant personnel install the first conductive component 2 on the insulating body 1, when the first auxiliary positioning portion 215 presses against the first main body positioning portion 15, the relevant personnel will be able to clearly feel that the first conductive component 2 has been inserted into the insulating body 1 to a certain position. At the same time, the relevant personnel can also see from the first engaging hole 13 that the first engaging protrusion 2141 has been engaged in the first engaging hole 13. In this way, the relevant personnel can determine that the first conductive component 2 has been correctly installed in the insulating body 1.

[0040] Similarly, as shown in Figures 4, 5, and 10, the second conductive member 3 may further include a second elastic engaging arm 314 and a second auxiliary positioning portion 315. The insulating body 1 also includes a second body positioning portion 16. One end of the second elastic engaging arm 314 is connected to the second contact portion 311; the other end of the second elastic engaging arm 314 is free and includes a second engaging protrusion 3141. The insulating body 1 may further include a second engaging hole 14, which and the first engaging hole 13 are respectively disposed on the upper and lower surfaces of the insulating body 1. The detailed description of the second elastic engaging arm 314, the second engaging protrusion 3141, the second engaging hole 14, the second auxiliary positioning portion 315, and the second body positioning portion 16 is the same as the description of the first elastic engaging arm 214, the first engaging protrusion 2141, the first engaging hole 13, and the first auxiliary positioning portion 215 described above and will not be repeated here. Among them, the first engaging hole 13 and the second engaging hole 14 can be roughly located on opposite sides of the insulating body 1; that is, the first elastic engaging arm 214 of the first conductive member 2 and the second elastic engaging arm 314 of the second conductive member 3 installed in the insulating body 1 are offset vertically (in the Z-axis direction). For example, as shown in Figure 4, the first elastic engaging arm 214 is located on the lower side of one end of the first contact portion 211 (in this case, the first bent portion 212 is located on the upper side of this end of the first contact portion 211), and the second elastic engaging arm 314 is located on the upper side of one end of the second contact portion 311 (in this case, the second bent portion 312 is located on the lower side of this end of the second contact portion 311).

[0041] It is worth mentioning that in actual applications, in addition to the first conductive member 2 and the second conductive member 3 respectively cooperating with the first engaging hole 13 and the second engaging hole 14 of the insulating body 1 through the first engaging protrusion 2141 and the second engaging protrusion 3141 to be fixed to the insulating body 1, the first conductive member 2, the second conductive member 3 and the insulating body 1 can also be designed through size, appearance, guide grooves, etc., so that the first conductive member 2 and the second conductive member 3 are respectively fixed in the insulating body 1 in a tight fit or limited manner, so that the range of movement of the first conductive member 2 and the second conductive member 3 relative to the insulating body 1 in any direction (for example, X-axis, Y-axis, Z-axis, etc.) is limited.

[0042] As shown in Figures 5, 8, 9, and 10, one end of the first cable 4 has a first conductive connector 41 (e.g., multiple core wires with the outer insulation removed), which can be connected to the first conductive member 2 by welding or ultrasonic welding. Similarly, one end of the second cable 5 has a second conductive connector 51, which can be connected to the second conductive member 3 by welding or ultrasonic welding.

[0043] As shown in Figure 9, the first conductive connector 41 can be positioned adjacent to the upper edge of the first conductive member 2. That is, the linear distance H4 between the upper edge of the first conductive connector 41 and the upper edge of the first conductive member 2 can be smaller than the linear distance H5 between the lower edge of the first conductive connector 41 and the lower edge of the first conductive member 2. Furthermore, the width of the first connecting portion 213 of the first conductive member 2 is smaller than the width of the terminal receptacle 12, and the first connecting portion 213 is positioned toward one side of the terminal receptacle 12, such that the distance H8 between the first connecting portion 213 and the lower inner surface of the terminal receptacle 12 is greater than the distance H9 between the first connecting portion 213 and the upper inner surface of the terminal receptacle 12.

[0044] As shown in Figure 10, the second conductive connector 51 can be positioned adjacent to the lower edge of the second conductive member 3. That is, the linear distance H6 between the upper edge of the second conductive connector 51 and the upper edge of the second conductive member 3 can be greater than the linear distance H7 between the lower edge of the second conductive connector 51 and the lower edge of the second conductive member 3. Furthermore, the width of the second connecting portion 313 of the second conductive member 3 is smaller than the width of the terminal receptacle 12, and the second connecting portion 313 is positioned toward one side of the terminal receptacle 12, such that the distance H10 between the second connecting portion 313 and the lower inner surface of the terminal receptacle 12 is smaller than the distance H11 between the second connecting portion 313 and the upper inner surface of the terminal receptacle 12. In other words, the first connecting portion 213 and the second connecting portion 313 located in the same terminal receptacle 12 are also vertically offset from each other.

[0045] As described above, by arranging the first conductive connector 41 adjacent to the upper edge of the first conductive component 2 and the second conductive connector 51 adjacent to the lower edge of the second conductive component 3, the heat dissipation gap S between the first cable 4 and the second cable 5 can be effectively maximized.

[0046] Please refer to Figures 11 to 13. Figure 11 is a schematic diagram of the docking connector of the present invention, Figure 12 is a partially exploded schematic diagram of the docking connector of the present invention, and Figure 13 is a cross-sectional schematic diagram along the section line XIII-XIII of Figure 1.

[0047] The docking connector 300 is a board-to-board connector that may include an insulating body 7 and at least one docking terminal assembly 8, which is the terminal assembly defined in the scope of the patent application. The insulating body 7 includes a terminal receiving slot 71. Each docking terminal assembly 8 includes two docking conductive plates 81. Each docking conductive plate 81 has a plurality of elastic arms 811 at one end, which are located within the terminal receiving slot 71. The other end of each docking conductive plate 81 is a flat plate portion 812. The flat plate portion 812 is generally plate-shaped and has a retaining arm 8121. As shown in Figures 1, 12, and 13, when the conductive plates 81 are located within the insulating body 7, the flat plate portion 812 of the docking terminal assembly 8 is separated by a partition structure 76 within the insulating body 7. The retaining arm 8121 of the flat plate portion 812 engages with a retaining structure 75 of the insulating body 7. A plurality of pins 813 extend from one side of the flat plate portion 812. These pins 813 are arranged in a row and extend beyond the insulating body 7 for electrical connection to a circuit board (not shown). The left and right sides of the terminal receptacle 71 each have a guide groove 72 for accommodating the guide post 18 of the connector 100 when mating with the connector 100. The end surfaces of the guide groove 72 are semicircular, and the upper and lower side surfaces of the terminal receptacle 71 have at least one heat dissipation hole 74. The insulating body 7 is provided with at least one heat dissipation groove 73 between two adjacent mating terminal groups 8. The heat dissipation groove 73 is in communication with the terminal receptacle 71. The multiple elastic arms 811 of two mating conductive plates 81 in the same mating terminal set 8 are arranged facing each other. The distal ends (free ends) of each elastic arm 811 are offset and close to each other and have a protrusion 8111 and a notch 8112. Each protrusion 8111 is arranged facing the notch 8112 of the elastic arm 811 of the other mating conductive plate 81 in the same mating terminal set 8. Each elastic arm 811 of each mating conductive plate 81 has one free end and the other fixed end, and the fixed ends of the multiple elastic arms 811 of each mating conductive plate 81 are connected to each other. Each of the mating conductive plates 81 also has a deflection section 8113. The two ends of the deflection section 8113 are respectively connected to the fixed sections and the flat plate 812 of the multiple elastic arms 811. The deflection section 8113 connects the multiple fixed sections and the flat plate 812 at an angle, so that the multiple fixed sections and the flat plate 812 are not located on the same axis.

[0048] As shown in FIG13 , when the connector 100 and the docking connector 300 are plugged into each other, the two docking conductive plates 81 of each docking terminal assembly 8 are inserted into one of the plug-in ports 11 and contact the two conductive plates (the first conductive plate 21 and the second conductive plate 31) located in the same plug-in port 11, and the multiple elastic arms 811 of each docking conductive plate 81 are elastically deformed.

[0049] As described above, by designing that each protrusion 8111 of each mating conductive sheet 81 is disposed facing the notch 8112 of another mating conductive sheet 81, during the process of mutual insertion of the connector 100 and the mating connector 300, the protrusion 8111 of each mating conductive sheet 81 and the notch 8112 of the opposite mating conductive sheet 81, which are elastically deformed by the push, will move toward each other, thereby increasing the elastic deformation space and deformation amount of the two mating conductive sheets 81, so that each mating conductive sheet 81 can provide a greater positive force.

[0050] Please refer to Figures 14 to 18 together. Figures 14 and 15 are schematic diagrams of the second embodiment of the connector of the present invention from different perspectives, Figure 16 is an exploded schematic diagram of the second embodiment of the connector of the present invention, Figure 17 is a partially exploded schematic diagram of the second embodiment of the connector of the present invention, and Figure 18 is a cross-sectional schematic diagram along the section line XVIII-XVIII of Figure 14.

[0051] This embodiment differs from the previous embodiment in that the direction in which all cables exit from connector 100 differs from the previous embodiment. The cable exit direction of connector 100 of this embodiment (e.g., the X-axis direction in FIG. 14 ) is different from a plugging direction of connector 100 (e.g., the Y-axis direction in FIG. 14 ), whereas the cable exit direction of connector 100 of the previous embodiment is substantially the same as the plugging direction of connector 100. Of course, connector 100 can be configured to have cables exit upward, downward, left, right, or in any other direction relative to the plugging direction, depending on actual needs.

[0052] The connector 100 of this embodiment further includes an insulating cover 6. The insulating cover 6 includes a first cover 61 and a second cover 62. Portions of the first cover 61 and the second cover 62 are detachably fixed to the insulating body 1, and the first cover 61 and the second cover 62 are detachably fixed to each other.

[0053] As shown in Figure 17 , the first conductive member 2 and the second conductive member 3 may further include a first deflector 22 and a second deflector 32, respectively. Each first deflector 22 includes a first fixing section 221 and a second fixing section 222. The first fixing section 221 is fixed to the first connecting portion 213 of the first conductive member 21, while the second fixing section 222 is electrically connected to the first cable 4. In this embodiment, the first fixing section 221 and the second fixing section 222 are sheet-like structures, with the length direction of the first fixing section 221 being different from the length direction of the second fixing section 222. Specifically, the first deflector 22 may be generally L-shaped. The provision of the first deflector 22 can change the outlet direction of the first cable 4. Similarly, the second deflector plate 32 is used to connect the second conductive member 3 and the second cable 5, thereby changing the direction of the second cable 5's output. The description of the first fixing section 321 and the second fixing section 322 of the second deflector plate 32 is the same as that of the first fixing section 221 and the second fixing section 222 of the first deflector plate 22, and will not be repeated here. In other embodiments, the first conductive plate 21 and the first deflector plate 22 may be integrally formed, and the second conductive plate 31 and the second deflector plate 32 may also be integrally formed. In other words, the first connecting portion 213 of the first conductive plate 21 includes the first deflector plate 22, forming an L-shape, while the second connecting portion 313 of the second conductive plate 31 includes the second deflector plate 32, forming an L-shape. As shown in Figure 16, when the first deflector plate 22 and the second deflector plate 32 are turned in the same direction (e.g., the positive X-axis), they can be offset in the vertical (Z-axis) direction to prevent the first deflector plate 22 and the second deflector plate 32 from contacting each other.

[0054] The insulating cover 6 is used to shield the steering blades so that they are not exposed. In practical applications, the insulating cover 6 may also include multiple isolation structures 63, each of which is used to isolate adjacent steering blades (the first steering blade 22 and the second steering blade 32) that are connected to the conductive sheet 81.

[0055] As described above, by designing the first cover 61 and the second cover 62 to be removably connected to the insulating body 1, personnel can decide whether to install the insulating cover 6 on the insulating body 1 based on actual wiring requirements. Conversely, if personnel wish to change the original wiring arrangement of the connector 100, they can simply remove or install the insulating cover 6 and replace the corresponding conductive components, thereby quickly changing the wiring direction of the connector 100.

[0056] In summary, the connector of the present invention increases the elastic deformation space and deformation amount of the two mating conductive sheets by arranging the protrusions of the elastic arms of the two mating conductive sheets of each terminal group to face the notches, so that each mating conductive sheet can provide a greater positive force and improve the current carrying capacity.
