Abstract
Description

[0002] In related technologies, the welding between terminals and conductors, especially the resistance welding between terminals and conductive leads of other electronic components, typically involves the following process: first, the bent conductive lead is installed from the inlet of the terminal slot into the slot; then, resistance welding is used to weld the conductive lead into the slot. During this process, to ensure the conductive lead can be smoothly installed into the slot, the width of the slot is much larger than the outer diameter of the conductive lead. However, this method makes it easy for the conductive lead to detach from the slot during welding, resulting in a high defect rate. To reduce the defect rate, workers usually perform a clamping process on the terminals before inserting the conductive lead into the slot and welding, thus closing the inlet of the slot due to clamping force before proceeding with the welding process.

[0034] In related technologies, the welding between terminals and conductors, especially the resistance welding between terminals and conductive leads of other electronic components, typically involves the following process: first, the bent conductive lead is installed into the terminal slot from the inlet; then, resistance welding is used to weld the conductive lead into the slot. During this process, to ensure the conductive lead can be smoothly installed into the slot, the width of the slot is much larger than the outer diameter of the conductive lead. However, this method makes it easy for the conductive lead to detach from the slot inlet during welding, resulting in a high defect rate. To reduce the defect rate, workers usually perform a clamping process on the terminals before inserting the conductive lead into the slot and welding, thus closing the slot inlet due to clamping force before proceeding with the welding process. However, the clamping process increases the labor cost of welding terminals and conductive leads, wasting manpower and resources.
[0035] In view of this, the present disclosure provides a conductive terminal for welding, which, when welded to the conductor, makes it difficult for the conductor to come out of the conductive terminal during the welding process without the need for a clamping process, thus saving on manual clamping costs.
[0036] Figure 1 This is a schematic diagram of the structure of a conductive terminal for welding according to an embodiment of the present disclosure. Figure 2 This is a schematic diagram showing the conductor 900 installed inside the conductive terminal for welding according to an embodiment of this disclosure. (See also...) Figure 1 and Figure 2 The conductive terminal for welding according to an embodiment of this disclosure includes a welding end 100. The welding end 100 is provided with a slot 11 and an inlet 12 communicating with the slot 11 and allowing a conductor 900 to enter. Thus, when the conductor 900 is installed into the slot 11, the conductor 900 can be installed into the slot 11 through the inlet 12.
[0037] Optionally, the conductor 900 is linear and bendable. For example, the conductor 900 can be a conductive pin or a conductive cable, etc. One end of the conductor 900 is used for electrical connection with other electronic components, and the other end is welded to the welding end 100 after being bent.
[0038] Optionally, the weld end portion 100 is further provided with a deformation notch 13. For example, there may be one or more deformation notches 13; for instance, one deformation notch 13 may be located on the weld end portion 100, or two deformation notches 13 may be located opposite each other on the weld end portion 100, with the opening directions of the two deformation notches 13 being opposite. For example, the deformation notch 13 may be semi-circular. The deformation notch 13 gives the weld end portion 100 a certain degree of deformability, making the weld end portion 100 less prone to deformation and damage.
[0039] The slot 11 includes a receiving section 111 and a guiding section 112. The guiding section 112 extends from the inlet 12 into the slot and allows the conductor 900 to pass through in a relatively compressive manner. In other words, when the conductor 900 passes through the guiding section 112 in the direction from the inlet 12 into the slot, the conductor 900 can be compressively passed through the guiding section 112 under the application of a downward pressure force.
[0040] Optionally, the width of the guide section 112 is configured to interference fit with the outer diameter (cross-sectional diameter) of the conductor 900. Thus, the outer diameter of the conductor 900 is larger than the width of the guide section 112, allowing the conductor 900 to be squeezed through the guide section 112 under a downward pressure during installation from the inlet 12 to the guide section 112.
[0041] The receiving section 111 communicates with the guiding section 112 to receive the conductor 900 for welding connection. In other words, when the conductor 900 enters from the inlet 12 and reaches the receiving section 111, the conductor 900 can be accommodated in the receiving section 111 and welded to the conductive terminal in a subsequent welding process.
[0042] Optionally, the welding between the conductor 900 and the receiving section 111 can be resistance welding. Resistance welding is a method that uses the resistance heat generated by the current passing through the workpiece and the contact point as a heat source to locally heat the workpiece while applying pressure for welding. When current passes through two conductive metals that are in close contact under pressure, a large amount of heat is generated at the contact point due to the high resistance at the contact point. This large amount of heat rapidly heats the metal at the contact point to a molten state, and then, under pressure, the molten parts of the two workpieces fuse together, forming a strong weld after cooling.
[0043] Optionally, the conductor 900 has a circular cross-section, and the bottom of the receiving section 111 forms an arc-shaped support surface that matches the circular cross-section of the conductor 900, so as to support the conductor 900 and allow the conductor 900 to better fit with the bottom of the receiving section 111, which helps to ensure that the conductor 900 is held relatively stably in the receiving section 111.
[0044] The connection between the receiving section 111 and the guiding section 112 features an increased groove width, forming a blocking portion 1121 that prevents the conductor 900, after being released from compression in the receiving section 111, from retracting into the guiding section 112. In other words, after the conductor 900 is compressed through the guiding section 112 and enters the receiving section 111, the increased groove width at the receiving section 111 releases the conductor 900 from its compressed state. It is understood that during the process of the conductor 900 being squeezed by the guide section 112, the conductor 900 undergoes elastic deformation, thereby reducing its outer diameter, which allows the conductor 900 to be squeezed through the guide section 112. After passing through the guide section 112, the conductor 900 returns to its original shape to release the squeeze. Or the guide section 112 undergoes elastic deformation, thereby increasing the groove width of the guide section 112, which allows the conductor 900 to be squeezed through the guide section 112. After passing through the guide section 112, the guide section 112 returns to its original shape. After the conductor 900 enters the receiving section 111 with the increased groove width, the conductor 900 is no longer squeezed, thus releasing the squeeze. When the conductor 900, after being released from compression, is welded to the welding position in the receiving section 111 and moves due to welding, the blocking part 1121 blocks the conductor 900, thereby preventing the conductor 900 from returning from the receiving section 111 to the guiding section 112. This makes it difficult for the conductor 900 to return from the guiding section 112 to the inlet 12 and to come out of the slot 11 from the inlet 12. As a result, even if no clamping force is applied to the inlet 12 to close it before welding, the conductor 900 is difficult to come out of the terminal during the welding process of the receiving section 111. This helps to save on manual clamping costs and improve the welding efficiency when welding the conductor 900 to the terminal.
[0045] Optionally, the guide section 112 is coaxially arranged with the inlet 12 and the receiving section 111. Thus, after the conductor 900 enters the inlet 12, under the action of vertical downward pressure, the conductor 900 can smoothly enter the guide section 112 from the inlet 12 and enter the interior of the receiving section 111 via the guide section 112.
[0046] In some examples, the guide segment 112 includes at least one compression portion. The compression portion protrudes radially inward from the inner wall of the slot 11, and the blocking portion 1121 is formed at the bottom of the guide segment 112.
[0047] In other examples, the guide segment 112 includes at least two opposing compression portions. The compression portions protrude radially inward from the inner wall of the slot 11, and the bottom of each compression portion forms the blocking portion 1121.
[0048] Specifically, at least two extrusion portions include a first extrusion portion 1122 and a second extrusion portion 1123. The first extrusion portion 1122 protrudes radially inward from the inner wall of the slot 11. The second extrusion portion 1123 protrudes radially inward from the inner wall of the slot 11 and is opposite to and spaced apart from the first extrusion portion 1122. The distance between the first extrusion portion 1122 and the second extrusion portion 1123 is configured to interference fit with the outer diameter of the conductor 900, and the bottom of both the first extrusion portion 1122 and the second extrusion portion 1123 is formed as the blocking portion 1121.
[0049] Optionally, each of the extrusion sections is provided with an inlet ramp 1124, which extends from the outside to the inside along the direction from the inlet 12 to the receiving section 111. Thus, the conductor 900 can easily enter the guide section 112 under the guidance of the inlet ramp 1124.
[0050] Therefore, during the process of installing the conductor 900 from the inlet 12 to the receiving section 111, a downward pressure can be applied to the conductor 900, thereby causing the conductor 900 to move in the direction from the inlet 12, the guide section 112 to the receiving section 111, and finally be pressed into the receiving section 111 and await welding. In the above process, since the conductor 900 is squeezed through the guide section 112 and enters the receiving section 111 under downward pressure, and after the conductor 900 enters the receiving section 111 where the groove width increases, the blocking part 1121 will block the conductor 900 from entering the guide section 112 from the receiving section 111. Therefore, after the conductor 900 enters the receiving section 111 through the guide section 112, it is difficult for it to enter the guide section 112 from the receiving section 111 and exit through the inlet 12. Therefore, after the conductor 900 is pressed into the receiving section 111, it is not necessary to perform a clamping process on the inlet 12 and the conductor 900 and the receiving section 111 can be directly welded. Thus, without the clamping process, it is difficult for the conductor 900 to come out of the conductive terminal during the welding process, saving manual clamping costs.
[0051] Optionally, the slot 11 further includes an inlet section 113. The inlet section 113 is disposed between the guide section 112 and the inlet 12, and its width gradually decreases along the direction from the inlet 12 to the guide section 112. Thus, the conductor 900 can easily enter the inlet 12 and, guided by the inlet section 113, smoothly enter the guide section 112.
[0052] Optionally, the conductive terminal for welding further includes a fixing part 200. The fixing part 200 is used to fix the terminal in one position to facilitate the fixing of the terminal, and the fixing part 200 is connected to the welding end 100.
[0053] Optionally, the fixing part 200 is provided with a plurality of fixing holes 21 for fasteners (e.g., screws) to pass through and be fastened to a fixing carrier. Optionally, the fixing part 200 is provided with positioning holes 22 for fitting around the outside of the positioning post. For example, the positioning holes 22 are located among the plurality of fixing holes 21, thereby achieving the positioning of the conductive terminal and making the conductive terminal more stable and less prone to movement after fixing. However, it is understood that the fixing part 200 of this disclosure can also achieve fixing and positioning in other ways, and this disclosure does not limit the specific structure of the fixing part 200.
[0054] Optionally, from the welding end 100 to the fixing part 200, the conductive terminal for welding extends in a straight line or in a bent shape. Thus, the conductive terminal can be a plate-shaped terminal or a bent terminal. Specifically, the specific shape of the conductive terminal can be adaptively adjusted according to the usage environment of the conductive terminal.
[0055] This disclosure also provides a conductive welding assembly, including a conductive terminal and a conductor 900 for welding as described above. The conductor 900 is disposed within and welded to the receiving section 111. Thus, in the welding preparation process of the conductive welding assembly of this disclosure, downward pressure is first applied to the conductor 900, causing it to move sequentially along the direction from the inlet 12, the guide section 112 to the receiving section 111, thereby press-fitting the conductor 900 into the receiving section 111 and awaiting welding. Furthermore, since the conductor 900 is difficult to detach from the inlet 12 through the guide section 112 during welding within the receiving section 111, after the conductor 900 is press-fitted into the receiving section 111, a clamping process at the inlet 12 is not required, and the conductor 900 and the receiving section 111 can be directly welded together. This allows the conductive welding assembly to be directly welded without a clamping process, resulting in high manufacturing efficiency and low manufacturing cost.
[0056] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
