[0035] The other of the two electrical terminals is connected to the side of the second sub-electrode opposite to the second boss.

[0036] In another implementation of this disclosure, the welding fixture further includes a template;

[0037] The template is connected to the side of the second electrode facing the first electrode, and the template is used to clamp the first workpiece.

[0038] In another implementation of this disclosure, the template includes a first submodule and a second submodule;

[0039] The first submodule is connected to the first sub-electrode, and the second submodule is connected to the second sub-electrode. There is a gap between the first submodule and the second submodule for accommodating the first workpiece.

[0040] Secondly, this disclosure provides a welding method based on the welding fixture described above, the welding method comprising:

[0041] A first workpiece and a second workpiece are provided, the first workpiece having a ventilated structure and the second workpiece having an open end and a hollow inner cavity;

[0042] The second workpiece is abutted against and electrically connected to the second electrode;

[0043] The ventilation structure of the first workpiece is aligned with the open end of the second workpiece;

[0044] The first electrode is abutted against and electrically connected to the first workpiece, so that the exhaust structure is connected to the ventilation structure;

[0045] The first electrode and the second electrode are switched on to melt a portion of the opening of the second workpiece, thereby welding the first workpiece and the second workpiece together.

[0046] In another implementation of this disclosure, connecting the first electrode and the second electrode includes:

[0047] The first and second workpieces are made of copper and have a conduction current of at least 8000A.

[0048] In another implementation of this disclosure, the welding method includes melting a portion of the opening of the second workpiece, which is a portion of the opening at one end of the second workpiece extending 0.3-1 mm toward the other end.

[0049] Thirdly, embodiments of this disclosure provide a welded workpiece, including a first workpiece and a second workpiece;

[0050] The first workpiece has a ventilated structure;

[0051] The second workpiece has an open and hollow inner cavity at one end;

[0052] The openings of the first workpiece and the second workpiece are sealed by welding, and the ventilation structure is directly opposite the opening of the second workpiece.

[0053] In yet another implementation of this disclosure, the first workpiece has a welding surface;

[0054] The welding surface has multiple ribs, and each rib is arranged around the four sides of the ventilation structure.

[0055] In yet another implementation of this disclosure, the welded workpiece is a socket for a receptacle.

[0056] Fourthly, embodiments of this disclosure provide a socket, including a socket sleeve, wherein the socket sleeve is the welded workpiece described above.

[0057] Fifthly, embodiments of this disclosure provide an electronic device including the welded workpiece described above.

[0058] The beneficial effects of the technical solutions provided in this disclosure are:

[0059] When welding the first workpiece and the second workpiece together using the welding fixture provided in this embodiment, the second workpiece is first abutted against and electrically connected to the second electrode. Then, the ventilation structure of the first workpiece is abutted against the opening end of the second workpiece. Next, the first electrode is abutted against and electrically connected to the first workpiece, so that the exhaust structure and the ventilation structure are connected and the first workpiece and the second workpiece are tightly abutted together. Finally, the first electrode and the second electrode are connected, so that a part of the opening of the second workpiece is melted due to instantaneous high temperature, and the first workpiece and the second workpiece are welded together.

[0060] Since the first electrode and the first workpiece are connected by an exhaust structure and a ventilation structure, and the first and second workpieces are connected by a ventilation structure and an open end, the high-temperature gas generated during the welding process will not remain in the inner cavity of the second workpiece. It can be discharged to the outside under the guidance of the ventilation and exhaust structures, thereby avoiding the high-temperature gas from affecting the welding between the first and second workpieces, improving the reliability of the welding, and thus improving the yield of the manufactured socket.

[0061] In other words, the welding fixture provided in this embodiment can achieve high-yield welding between the first workpiece and the second workpiece. Thus, the first and second workpieces can be used to manufacture socket sleeves. The first workpiece is a copper busbar, and the second workpiece is a copper pillar with an inner cavity, meaning the copper pillar is a hollow structure, which effectively reduces material costs.

[0087] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0088] A socket is a common electronic device used to plug in electrical equipment, thereby providing power to the equipment.

[0089] In related technologies, sockets are equipped with socket sleeves. For some types of sockets (such as French sockets), the socket sleeve consists of a copper busbar and a solid copper post, with the copper busbar and the solid copper post riveted together.

[0090] However, the material cost of solid copper pillars is high, as is the cost of riveting, resulting in a high manufacturing cost for the inserts. Designing the copper pillars as hollow structures would lead to a significant decrease in processing yield.

[0091] To address the aforementioned technical problems, this disclosure provides a welding fixture. Figure 1 This is a schematic diagram of the welding fixture, which is used to weld the first workpiece 100 and the second workpiece 200.

[0092] Figure 2 This is a structural schematic diagram of the first workpiece 100. Figure 3 This is a structural schematic diagram of the second workpiece 200, combined with... Figure 2 and Figure 3 The first workpiece 100 has a ventilation structure 1100, and the second workpiece has an open and hollow inner cavity.

[0093] See you again Figure 1 In this embodiment, the welding fixture includes a first electrode 10 and a second electrode 20; one end face of the first electrode 10 has an exhaust structure 110, the first electrode 10 abuts against and is electrically connected to the first workpiece 100, and the exhaust structure 110 is connected to the ventilation structure 1100; the second electrode 20 abuts against and is electrically connected to the second workpiece 200; the welding fixture is configured to weld the first workpiece 100 and the second workpiece 200 together, and the ventilation structure 1100 is connected to the opening of the inner cavity.

[0094] When welding a first workpiece and a second workpiece together using the welding fixture provided in this embodiment, the second workpiece is first abutted against and electrically connected to the second electrode (see [link to documentation]). Figure 4 Then, the ventilation structure of the first workpiece is abutted against the open end of the second workpiece (see...). Figure 5 Then, the first electrode is brought into contact with and electrically connected to the first workpiece (see...). Figure 6 This allows the exhaust structure to connect with the ventilation structure, and the first and second workpieces to be tightly abutted together. Finally, the first and second electrodes are connected, causing a portion of the opening of the second workpiece to melt due to instantaneous high temperature, and the first and second workpieces are welded together.

[0095] Since the first electrode and the first workpiece are connected by an exhaust structure and a ventilation structure, and the first and second workpieces are connected by a ventilation structure and an open end, the high-temperature gas generated during the welding process will not remain in the inner cavity of the second workpiece. It can be discharged to the outside under the guidance of the ventilation and exhaust structures, thereby avoiding the high-temperature gas from affecting the welding between the first and second workpieces, improving the reliability of the welding, and thus improving the yield of the manufactured socket.

[0096] In other words, the welding fixture provided in this embodiment can achieve high-yield welding between the first workpiece and the second workpiece. Thus, the first and second workpieces can be used to manufacture socket sleeves. The first workpiece is a copper busbar, and the second workpiece is a copper pillar with an inner cavity, meaning the copper pillar is a hollow structure, which effectively reduces material costs.

[0097] Figure 7 This is a schematic diagram of the structure of the first electrode, combined with... Figure 7 In this embodiment, the exhaust structure 110 includes an exhaust groove 111 and an exhaust channel 112. The exhaust groove 111 is located on the end face of the first electrode 10, and the exhaust channel 112 is located on the side of the first electrode 10 and communicates with the exhaust groove 111.

[0098] The exhaust structure 110 is located on the end face of the first electrode 10, and the opening of the exhaust groove 111 directly abuts against the first workpiece 100. During the welding process, the high-temperature gas generated between the first workpiece 100 and the second workpiece 200 enters the exhaust groove 111 and is dissipated to the outside under the guidance of the exhaust channel 112, thereby effectively preventing the high-temperature gas from affecting the welding between the first workpiece 100 and the second workpiece 200.

[0099] For example, there are multiple exhaust channels 112, and each exhaust channel 112 is arranged at intervals along the circumference of the exhaust groove 111.

[0100] This arrangement of the exhaust channels 112 can effectively increase the speed at which the high-temperature gas in the exhaust trough 111 is discharged, allowing the high-temperature gas in the exhaust trough 111 to be quickly discharged from each exhaust channel 112.

[0101] In some examples, the exhaust channel 112 is an open slot, and the slot opening of the exhaust channel 112 and the slot opening of the exhaust groove 111 are both located on the end face of the first electrode 10. This allows the high-temperature gas to enter the exhaust channel 112 directly after it is generated, in addition to entering the exhaust groove 111, thereby further increasing the speed of exhausting the high-temperature gas.

[0102] For example, the diameter of the first electrode 10 is 5 mm, the exhaust groove 111 is coaxial with the first electrode 10, the diameter of the exhaust groove 111 is 2.5-3 mm, and the diameter of the exhaust channel 112 is 0.3-0.5 mm.

[0103] In some examples, the exhaust structure 110 includes an exhaust through-hole that extends through the two opposite end faces of the first electrode 10.

[0104] In the above implementation, the function of the vent hole is similar to that of the vent groove 111. During the welding process, the high-temperature gas generated between the first workpiece 100 and the second workpiece 200 enters the vent hole and is dissipated to the outside under the guidance of the vent channel 112. In addition, since the vent hole penetrates the two opposite end faces of the first electrode 10, the high-temperature gas can also enter from one end of the vent hole and exit from the other end.

[0105] It should be noted that if the exhaust structure 110 includes an exhaust groove 111, it does not need to include an exhaust through hole; conversely, if the exhaust structure 110 includes an exhaust through hole, it does not need to include an exhaust groove 111.

[0106] For example, the first electrode 10 is made of copper alumina, which has good conductivity.

[0107] Figure 8 This is a sectional view of the welding fixture, combined with... Figure 8 In this embodiment, the wall of the clamping hole 210 has a clamping part 220, which is used to clamp the part of the second workpiece 200 near the opening. The clamping part 220 and the second workpiece 200 are electrically connected.

[0108] For example, the clamping part 220 is coaxial with the clamping hole 210, and the clamping part 220 protrudes from the hole wall of the clamping hole 210. One side of the clamping part 220 is flush with the opening of the clamping hole 210 near the template 30.

[0109] In the above implementation, when the second workpiece 200 is inserted into the clamping hole 210, since the clamping part 220 protrudes from the wall of the clamping hole 210, the second workpiece 200 only contacts the clamping part 220 and not the wall of the clamping hole 210. This creates a gap between the second workpiece 200 and the wall of the clamping hole 210, which helps to dissipate heat during the welding process.

[0110] In addition, since the second workpiece 200 only contacts the clamping part 220, the clamping part 220 clamps the second workpiece 200 near the part protruding from the clamping hole 210, that is, near the welding position of the second workpiece 200. In this way, it is beneficial to local concentration of current, thereby improving the effect of instantaneous high-temperature welding.

[0111] In some examples, the clamping portion 220 surrounds and fits against the outer surface of the second workpiece 200. This design effectively ensures that the clamping portion 220 is in full contact with the outer surface of the second workpiece 200, which improves both clamping stability and electrical connection performance.

[0112] For example, the opening distance between the clamping part 220 and the second workpiece 200 is 0.3 to 1 mm. That is, the opening end of the second workpiece 200 protrudes from the clamping part 220 by a certain distance, which is the length of the second workpiece 200 that melts during welding. Setting the distance to 0.3 to 1 mm can ensure the stability of the weld.

[0113] See also Figure 8 In this embodiment, the welding fixture also includes an insulating pad 40, which is located below the clamping part 220, and the side of the insulating pad 40 facing the clamping part 220 abuts against the second workpiece 200.

[0114] In the above implementation, the insulating pad 40 is used to support the second workpiece 200 inserted into the clamping hole 210, preventing the second workpiece 200 from falling out of the clamping hole 210. In addition, since the insulating pad 40 is an insulating component, the current of the second electrode 20 can only be conducted to the second workpiece 200 through the clamping part 220, thereby ensuring current concentration and facilitating the generation of instantaneous high temperature.

[0115] For example, the spacing between the insulating pad 40 and the clamping portion 220 is adjustable so that the opening of the second workpiece 200 extends out of the clamping portion 220 by 0.3 to 1 mm.

[0116] In other words, by changing the installation position of the insulating pad 40, the relative distance between the insulating pad 40 and the clamping part 220 can be adjusted, thereby adjusting the height at which the opening of the second workpiece 200 extends out of the clamping part 220.

[0117] Figure 9 This is a schematic diagram showing the open and closed states of the welding fixture. Figure 9 The upper part is a schematic diagram of the welding fixture in the open state. Figure 9 The lower part is a schematic diagram of the closed state of the welding fixture, combined with... Figure 9 In this embodiment, the second electrode 20 includes a first sub-electrode 230 and a second sub-electrode 240.

[0118] The first sub-electrode 230 has a first boss 231 on one side, a first semi-hole groove 232 on one side, and a first semi-flange 233 on the first semi-flange 232. The second sub-electrode 240 has a second boss 241 on one side, a second semi-hole groove 242 on one side, and a second semi-flange 243 on the second semi-flange 242. The first semi-flange 232 and the second semi-flange 242 are opposite to each other to form a clamping hole 210, and the first semi-flange 233 and the second semi-flange 243 are opposite to each other to form a clamping portion 220.

[0119] In the above implementation, the second electrode 20 consists of two parts: a first sub-electrode 230 and a second sub-electrode 240. When the first sub-electrode 230 and the second sub-electrode 240 are assembled together, the first half-hole groove 232 and the second half-hole groove 242 are aligned to form a clamping hole 210, and the first half-flange 233 and the second half-flange 243 are aligned to form a clamping part 220. After the first sub-electrode 230 and the second sub-electrode 240 are separated, the second workpiece 200 can be easily inserted, thereby improving the ease of use of the welding fixture.

[0120] In this embodiment, the welding fixture also includes a first clamp 510, a second clamp 520, and a locking member 530.

[0121] One end of the first clamp 510 is hinged to one end of the second clamp 520, and the other ends of the first clamp 510 and the second clamp 520 are detachably connected by a locking member 530. The first clamp 510 is connected to the side of the first sub-electrode 230 that is away from the second sub-electrode 240, and the second clamp 520 is connected to the side of the second sub-electrode 240 that is away from the first sub-electrode 230.

[0122] In the above implementation, during the opening and closing of the welding fixture, the first sub-electrode 230 moves with the first clamp 510, and the second sub-electrode 240 moves with the second clamp 520. Before opening the welding fixture, the locking member 530 is released, and after closing the welding fixture, the locking member 530 is locked, thereby ensuring a stable assembly between the first sub-electrode 230 and the second sub-electrode 240.

[0123] For example, the locking member 530 is a helical spring with hooks at both ends, and the two ends of the locking member 530 are detachably hooked onto the first clamp 510 and the second clamp 520 respectively via the hooks.

[0124] Figure 10 This is a schematic diagram of the second electrode structure, combined with... Figure 10In this embodiment, the second electrode 20 includes two electrical terminals 250. One of the two electrical terminals 250 is connected to the side of the first sub-electrode 230 that is away from the first boss 231, and the other of the two electrical terminals 250 is connected to the side of the second sub-electrode 240 that is away from the second boss 241.

[0125] In the above implementation, the first electrode 10 is electrically connected to the positive terminal of the power supply, and the two electrical terminals 250 are electrically connected to the negative terminal of the power supply. Through the two electrical terminals 250, the electrical connection between the first sub-electrode 230 and the second sub-electrode 240 and the negative terminal of the power supply can be realized.

[0126] See also Figure 10 In this embodiment, the welding fixture also includes a template 30, which is connected to the side of the second electrode 20 facing the first electrode 10. The template 30 is used to clamp the first workpiece 100.

[0127] In this embodiment, the first sub-electrode 230 has a first groove 234 on the side facing the template 30, and the second sub-electrode 240 has a second groove 244 on the side facing the template 30. The first groove 234 and the second groove 244 are connected.

[0128] The template 30 includes a first sub-module 310 and a second sub-module 320. The first sub-module 310 is located in the first groove 234 and is connected to the first sub-electrode 230. The second sub-module 320 is located in the second groove 244 and is connected to the second sub-electrode 240. There is a gap between the first sub-module 310 and the second sub-module 320 for accommodating the first workpiece 100.

[0129] In the above implementation, the first groove 234 and the second groove 244 provide accommodating space for the first sub-module 310 and the second sub-module 320, respectively, so that the first sub-module 310 and the second sub-module 320 can be stably mounted on the first sub-electrode 230 and the second sub-electrode 240. Through the first sub-module 310 and the second sub-module 320, a stable clamping of the first workpiece 100 can be achieved.

[0130] For example, both the first submodule 310 and the second submodule 320 are made of non-metallic high-temperature resistant materials, such as bakelite and bakelite, and this disclosure does not limit them.

[0131] Figure 11 A flowchart of a welding method provided in this disclosure embodiment, the welding method being based on Figure 1-10 The welding fixture shown. Combined Figure 11 The welding method includes:

[0132] Step 101: Provide a first workpiece 100 and a second workpiece 200. The first workpiece 100 has a ventilated structure 1100, and the second workpiece 200 has an open and hollow inner cavity.

[0133] In the above implementation, the ventilation structure 1100 provided on the first workpiece 100 can play an auxiliary role in exhausting gas, which is conducive to the discharge of high-temperature gas. The protruding rib 1200 is used to abut against the second workpiece 200, which effectively reduces the contact area between the first workpiece 100 and the second workpiece 200, increases the current density, and is conducive to generating instantaneous high temperature during the welding process.

[0134] For example, the first workpiece 100 is H62 copper, and the ventilation structure 1100 is hole-shaped with a diameter of 1-2 mm.

[0135] For example, the second workpiece 200 is made of H62 copper and is formed by multiple stretching of the sheet metal.

[0136] In some examples, the surface of the second workpiece 200 is electroplated (nickel-plated). Before welding, the electroplating at the welding area needs to be removed to increase the intermetallicity between the second workpiece 200 and the first workpiece 100. Of course, in other examples, the surface of the second workpiece 200 is not electroplated, in which case direct welding is possible.

[0137] Step 102: Connect the second workpiece 200 to the second electrode 20 and then electrically connect them.

[0138] Step 103: Abut the ventilation structure 1100 of the first workpiece 100 against the open end of the second workpiece 200.

[0139] Step 104: Connect the first electrode 10 to the first workpiece 100 and make them electrically connected, so that the exhaust structure 110 and the ventilation structure 1100 are connected.

[0140] Step 105: Connect the first electrode 10 and the second electrode 20 to melt a portion of the opening of the second workpiece 200, thereby welding the first workpiece 100 and the second workpiece 200 together.

[0141] In step 105, the power is turned on, allowing current to flow sequentially through the first electrode 10, the first workpiece 100, the second workpiece 200, and the second electrode 20. This causes a momentary high temperature to be generated between the first workpiece 100 and the second workpiece 200 due to the large current, resulting in the melting and welding of the portion of the open end of the second workpiece 200 that contacts the first workpiece 100. Because the exhaust structure 110, the ventilation structure 1100, and the opening of the second workpiece are in contact, the high-temperature gas generated during welding can be discharged to the outside under the guidance of the exhaust structure 110. This prevents the high-temperature gas from affecting the welding between the first workpiece 100 and the second workpiece 200, improving the reliability of the welding and thus increasing the yield of the manufactured socket.

[0142] For example, the first workpiece 100 and the second workpiece 200 are copper parts, and the conduction current is at least 8000A.

[0143] In the above implementation, the conduction current is designed to be above 8000A, which ensures good welding of the copper first workpiece 100 and the second workpiece 200. It should be noted that if the first workpiece 100 and the second workpiece 200 are made of other materials, the conduction current should also be changed accordingly, but this disclosure does not impose any restrictions on this.

[0144] Figure 12 This is a schematic diagram of the structure of a workpiece provided in an embodiment of the present disclosure, combined with... Figure 12 The welding fixture passes through Figure 1-10 The welding fixture shown includes a first workpiece 100 and a second workpiece 200. The first workpiece 100 has a ventilation structure 1100, and the second workpiece 200 has an open and hollow inner cavity. The openings of the first workpiece 100 and the second workpiece 200 are sealed and welded together. The ventilation structure 1100 is directly opposite the opening of the second workpiece 200.

[0145] Because this tooling passes through Figure 1-10 The welding fixture shown is manufactured so that the welding yield between the first workpiece 100 and the second workpiece 200 can be guaranteed.

[0146] For example, the first workpiece has a welding surface with a plurality of ribs 1200, each rib 1200 being arranged around the ventilation structure 1100.

[0147] In the above implementation, the welding surface of the first workpiece 100 refers to the surface where the first workpiece 100 and the second workpiece 200 are welded together. The protruding rib 1200 is used to abut against the second workpiece 200, effectively reducing the contact area between the first workpiece 100 and the second workpiece 200, increasing the current density, and facilitating the generation of instantaneous high temperature during the welding process.

[0148] In some examples, the welded workpiece is a socket for a receptacle.

[0149] Because the second workpiece 200 is a hollow structure, the material cost of this welding fixture can be controlled. When this welding fixture is applied to the socket sleeve, the first workpiece 100 is a copper busbar, and the second workpiece 200 is a copper pillar. The copper pillar has an inner cavity, that is, the copper pillar is a hollow structure, which can effectively reduce material costs.

[0150] This disclosure provides a socket, which includes a socket sleeve, wherein the socket sleeve is... Figure 12 The welded workpiece shown.

[0151] Because the socket's socket sleeve is Figure 12 The welded workpiece shown has therefore the following characteristics: Figure 12 The full benefits of the welded workpiece shown will not be elaborated here.

[0152] This disclosure provides an electronic device, which includes... Figure 12 The welded workpiece shown.

[0153] Because the electronic device includes Figure 12 The welded workpiece shown has therefore the following characteristics: Figure 12 The full benefits of the welded workpiece shown will not be elaborated here.
