Description

Technical Field

[0001] The utility model relates to the technical field of electronic manufacturing, in particular to a copper busbar limiting device and a copper busbar. Background Art

[0002] Copper busbars, also known as copper busbars or copper busbars, are flat plate-shaped conductors made of copper. They carry current and connect electrical equipment in the circuit. Since the copper busbar has a long span and no support at the bottom, it will sway left and right. In SMT (Surface Mounted Technology) welding, auxiliary tools such as iron blocks are needed for straightening, and in wave soldering, pressure rods are needed for straightening. At present, most copper busbars have achieved fully automatic SMT welding. During SMT welding, the PIN pins are pressed on the surface of the through-holes of the circuit board, resulting in no gaps on the surface of the through-holes and tin beads. This results in the need for manual processing of these tin beads, which greatly affects the overall welding quality and welding efficiency. Summary of the invention

[0019] refer to Figure 1 The utility model provides a copper bar limiting device 100, which is used for limiting the position of a copper bar 200. The copper bar limiting device 100 comprises a base block 101 and two clamping arms 102 symmetrically arranged on the base block 101. The copper bar 200 can be limited and fixed during welding through the cooperation between the two clamping arms 102 and the base block 101, and a certain gap can be formed between the bottom of the copper bar 200 and the circuit board, effectively avoiding the formation of tin beads, and well solving the shortcomings existing in the background technology, and improving the welding quality and welding efficiency of the copper bar 200.

[0020] Next, as a preferred embodiment, the clamping arm 102 includes a connecting portion 103, an inclined portion 104 and a supporting portion 105 which are sequentially connected from bottom to top, the connecting portion 103 is connected to the base block 101, the inclined portion 104 is inclined toward the direction of the clamping arm 102 opposite thereto, and a buffer area for installing the copper busbar 200 is formed between the two inclined portions 104, the supporting portion 105 is arranged above the buffer area, and when the copper busbar 200 is arranged between the two clamping arms 102, the supporting portion 105 is arranged to abut against the outer wall of the copper busbar 200. That is to say, when the copper bar 200 is arranged between the two clamping arms 102, the copper bar 200 will be placed on the circuit board for welding, and the pin point on the copper bar 200 will extend into the through hole of the circuit board, and then under the action of the copper bar limiting device 100, the base block 101 will hold up the copper bar 200 so that the copper bar 200 and the bottom and the circuit board form a gap, effectively avoiding the formation of tin beads and improving welding efficiency. And under the action of the abutting portion 105 of the two clamping arms 102, the position of the copper bar 200 will be limited to avoid the copper bar 200 from shaking during welding and improve welding quality. Secondly, the setting of the inclined portion 104 is to provide the space between the two clamping arms 102 for the copper bar 200 to be placed, and the space is the above-mentioned buffer area, which improves the fluency of the copper bar 200 to be placed, and can also reduce the friction between the copper bar 200 and the clamping arm 102 when the copper bar 200 is placed, and protect the integrity of the copper bar 200 structure.

[0021] In addition, as another preferred embodiment, the connecting portion 103, the inclined portion 104 and the abutting portion 105 are integrally formed, thereby improving the structural strength of the entire clamping arm 102 and extending its service life.

[0022] As another preferred embodiment, the clamping arm 102 and the base block 101 are integrally formed, thereby improving the structural strength of the overall copper bar limiting device 100 and extending its service life.

[0023] As another preferred embodiment, the clamping arm 102 is made of plastic. The clamping arm 102 made of plastic can further improve the clamping force when clamping the copper busbar 200, and its plasticity is strong, which can well prevent the structure of the copper busbar 200 from being damaged, and is easy to use.

The matching installation relationship between the copper bar 200 and the copper bar limiting device 100 is the same as described above, and will not be repeated here.

[0025] In addition, a support column is provided at the bottom of the main body, which is used to assist the copper bar limiting device 100 to support the copper bar 200, thereby improving the stability of the copper bar 200 after being installed in the circuit board, thereby facilitating the improvement of welding quality.
