Description

Improved generation conducting block

Technical Field

The application relates to the technical field of conducting blocks, in particular to an improved conducting block.

Background

A conductive bump refers to a bulk object that is capable of conducting electricity effectively, typically made of metal or other material with good electrical conductivity properties. The conductive block has good conductivity and low resistance and low voltage drop. Conductive bumps are commonly used for connection and grounding applications. For example, on a circuit board, conductive bumps are used to connect between components or with leads on the circuit board to ensure the transmission of electrical signals and connectivity of current. And the conductive block also has good heat conduction performance, and can help to rapidly spread and radiate generated heat so as to keep the stable operation of the equipment and prevent overheating. By connecting the cable to the conductive block, it is ensured that current or signals can be efficiently transferred from the cable to the conductive block, making an electrical connection.

In the prior art, a soldering method is generally used for connecting a conductive block and a cable, after an insulating layer of the cable is stripped, a proper amount of soldering tin is applied to a metal contact of the conductive block, and soldering iron is used for heating, so that the soldering tin is melted to realize good combination of the conductive block and the cable. But the soldering cost is higher and more soldering materials and equipment are required. Thus, low cost connection of the conductive block and the cable can be achieved by means of resistance welding. Resistance welding is a welding method in which a welding target member is locally heated by resistance heat generation, and a heated portion is joined by a pressurizing force. However, when the electric resistance welding is used for welding the conductive block and the cable, the conductive block needs to be heated for a long time, and when the cable is not bound to the shell, the copper wires in the cable are easy to be scattered, so that damage such as broken strands of the cable, heating of a joint and the like can occur during subsequent use, and normal use of the conductive block is affected.

In the description of the present specification, reference to the terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

As shown in the drawings, the present utility model discloses an improved conductive block, a first welding part 101 and a second welding part 102 are provided on a conductive block 100, and the first welding part 101 and the second welding part 102 are protruded outwards from the conductive block 100, and a gap is provided between the first welding part 101 and the second welding part 102.

Resistance welding is a welding method in which a welding target member is locally heated by resistance heat generation, and a heated portion is joined by a pressurizing force. When connecting the conductive block 100 and the cable 200 by resistance welding, it is first necessary to peel off a part of the insulation layer outside the cable 200, expose the wires inside, and clean the welded portion of the conductive block 100; placing the exposed wire end of the cable 200 above the first welding part 101 and the second welding part 102 which are arranged on the conductive block 100 and protruding upwards, and ensuring good contact between the wire of the cable 200 and the first welding part 101 and the second welding part 102; the welding electrode is tightly contacted with the conductive block 100, ensuring good contact and heat conduction; resistance heating occurs by application of an appropriate current through the electrodes. Since the conductive block 100 is provided with the first and second welding parts 101 and 102 protruding outward in parallel. The welding current can flow from the raised area of the conductive block 100 in the welding process, the shape of the raised first welding part 101 and the raised second welding part 102 are uneven, so that the welding current path is prolonged, the resistance value of the first welding part 101 and the second welding part 102 is increased, the heating is fastest, the first welding part 101 and the second welding part 102 can quickly reach the melting point temperature, become a softened state, and the conducting wire of the cable 200 is tightly connected with the first welding part 101 and the second welding part 102 by applying pressure to the cable 200 and the conductive block 100, so that good combination between the cable 200 and the conductive block 100 is realized. When the welded area cools, the weld solidifies and forms a stable and reliable welded connection that provides good electrical connection and mechanical fastening properties.

And because the first welding part 101 and the second welding part 102 which are arranged at the conducting block 100 in parallel and protrude outwards, the welding current distribution is more uniform, so that the welding current can uniformly flow through welding spots, the thermal stress concentration is reduced, and the quality of the welding seam between the cable 200 and the conducting block 100 is ensured. And the two welding parts arranged in parallel also increase the contact surface between the wires of the cable 200 and the conductive block 100, further improve the quality and stability of the welding seam, provide better current transmission and heat conduction performance, promote the melting and diffusion of welding materials and obtain higher welding connection strength.

Further preferably, in other embodiments of the present application, the distance between the first welded portion 101 and the second welded portion 102 may be optionally set to 1.0mm-2.0mm. When the resistance welding cable 200 and the conductive block 100 are used, the size of the gap between the first welding part 101 and the second welding part 102 arranged in parallel affects the distribution of the current between the first welding part 101 and the second welding part 102, and a smaller gap causes the current to be more concentrated in the narrow space between the first welding part 101 and the second welding part 102, resulting in problems of higher current density and overheating of welding; smaller gaps also increase heat conduction between the first weld 101 and the second weld 102, potentially causing the high temperature region to spread to adjacent regions, increasing the risk of thermal stress and deformation of the weld joint. And an excessive gap may cause current to be dispersed between the first welded portion 101 and the second welded portion 102, the welding density is low, and uniform heating is insufficient. This may result in the weld area not reaching the desired temperature, thereby affecting the quality and strength of the weld. The distance between the first welding part 101 and the second welding part 102 may be set to 1.0mm-2.0mm to ensure the strength of the quality of the welding connection of the cable 200 and the conductive block 100.

Further preferably, in other embodiments of the present application, the height of the protrusion of the first welding portion 101 and the second welding portion 102 may be optionally set to 0.2mm to 0.3mm. The height values of the protrusions of the first and second soldering parts 101 and 102 will directly affect the size of the soldering area of the cable 200 and the conductive block 100. However, too high a protrusion height may result in additional filler material consumption during the welding process. Higher bumps require more solder fill material to fill the bump space, increasing solder cost and material waste; while a lower bump height means a smaller contact area of the cable 200 with the conductive block 100, directly affecting the strength and stability of the soldered connection and resulting in a reduced load transfer capability of the soldered joint. The protruding height of the first and second solder joints 101 and 102 may be set to 0.2mm to 0.3mm to ensure the strength of the quality of the solder connection of the cable 200 and the conductive block 100. The lengths of the first welding part 101 and the second welding part 102 are matched with the diameters of the cable 200, so that the cable 200 can be completely placed above the first welding part 101 and the second welding part 102, and the welding contact area of the cable 200 and the conductive block 100 is ensured, so that the strength of the welding connection quality of the cable 200 and the conductive block 100 is ensured.

Further preferably, in other embodiments of the present application, the first solder 101, the second solder 102, and the conductive block 100 are integrally formed. The first welding part 101, the second welding part 102 and the conductive block 100 are integrally formed, so that the use of parts and the waste of materials are reduced, the strength and the stability of the conductive block 100 can be improved, the integral forming can manufacture a complete structure in a direct forming mode, the use of parts and the waste of materials are reduced, and the manufacturing cost of the conductive block 100 is reduced.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
