Description

Technical Field

[0001] The utility model relates to the technical field of cooling fan controller modules, in particular to an integrated sealed copper busbar assembly for connecting a wiring harness and a circuit board. Background Art

[0002] In order to meet the wiring and EMC requirements of electrical current, existing cooling fan controllers usually add copper bars, copper wires, and brackets to the cooling fan controllers to increase the overcurrent capacity in the circuit and meet the relevant requirements of the EMC standards. The copper bar assembly currently in mass production is assembled by assembling the copper bar and the plastic bracket to form a copper bar assembly. The wire is passed through the wire hole of the plastic bracket and welded to the copper bar. The copper bar assembly is then assembled on the end cover. The copper bar pins pass through the circuit board and are fixed with a soldering iron. Finally, sealant is injected, and the cover is covered and wait for the sealant to solidify. This process is relatively complicated, and is inefficient when used in automated assembly line operations. The quality is not necessarily reliable, and there is a high probability of problems due to too many links.

[0003] At present, this structure has the following defects in mass production:

[0004] 1. The copper busbar assembly, circuit board, and wiring harness assembly are all assembled in the end cover assembly. If an installation link is missed during the production process, it is difficult to find out. After the final inspection, all of them need to be disassembled to find out the specific cause, which is relatively cumbersome.

[0005] 2. Due to the toughness of the copper busbar, the exposed pins are relatively long and the size is easily deformed under stress. When assembled with the circuit board, sometimes the copper busbar pins are difficult to pass through the circuit board pad holes, increasing the time cost.

[0006] 3. At the same time, there is no cover plate to block the welding point between the copper busbar and the wiring harness, which is exposed to the air and completely relies on sealant for protection. If the sealant is damaged or incomplete, the wires are exposed, which can easily cause risks such as aging, moisture, loose wires, reduced overcurrent capacity, and shortened service life. Utility Model Content

[0007] The utility model aims to provide an integrated sealed copper busbar assembly for connecting a wiring harness and a circuit board, so as to solve the defects in the prior art.

[0008] In order to solve the above technical problems, the utility model provides an integrated sealed copper busbar assembly for connecting a wiring harness and a circuit board, comprising a plastic bracket and a plurality of copper busbars which are injection molded as one with the plastic bracket;

[0009] One end of the copper busbar extends into the welding space of the plastic bracket for connecting the wiring harness; the other end extends to the outside of the plastic bracket for connecting the circuit board of the end cover;

[0010] An upper end cover is clamped above the welding space, and a lower end cover is clamped below the welding space, so that the welding space forms a sealed space, and sealant is filled in the welding space to wrap the welding part of the wiring harness and the copper busbar.

[0011] Preferably, a plurality of the copper bars are arranged and distributed at intervals in the plastic bracket.

[0012] Preferably, the middle portion of each copper busbar is injection-molded as one piece with the plastic bracket, one end portion of the copper busbar extends into the welding space, and the other end extends to the outside of the plastic bracket.

[0013] Preferably, a plurality of wire grooves are provided on the side wall of the plastic bracket, so that the wires of the wiring harness can pass through the wire grooves and be welded to the copper busbar in the welding space.

[0014] Preferably, a gluing hole is provided on the upper end cover, and sealant is filled into the welding space through the gluing hole.

[0015] Preferably, the upper end cover is also provided with an air hole for discharging the air in the welding space when filling the sealant.

[0016] Preferably, first buckles are provided on both sides of the upper end cover, and the upper end cover is snapped onto the plastic bracket by pressing.

[0017] Preferably, a plurality of insulating partitions are vertically arranged on the lower end cover, and the insulating partitions are inserted between two adjacent copper bars.

[0018] Preferably, second buckles are provided on both sides of the lower end cover, and the lower end cover is snapped under the plastic bracket by pressing.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the original state, the copper busbar assembly and the wiring harness welding point are outside the control module and are only protected by sealant. If the sealant is damaged, it will be directly exposed to the outside, causing various adverse consequences. The utility model separates the wiring harness assembly from the end cover assembly, and adds an additional welding space for the welding of the copper busbar and the wire. It has double protection of sealant and plastic bracket. If the glue is less after curing, it can also be filled from the glue hole. At the same time, the copper busbar assembly has a shorter exposed copper busbar length, and the copper busbar is not easy to deform, which reduces the workload during the welding process; the copper busbar assembly is an integrated structure, and the corresponding assembly process is simple, which can reduce the assembly process, reduce labor costs, and improve work efficiency. After welding with the wiring harness assembly, it can also be regarded as a new component, which is firm and not easy to damage, and safe and convenient to transport.
