Description

Technical Field

[0001] The utility model relates to the field of electrical technology, and more specifically to a high-temperature resistant pickling and oxidation copper busbar. Background Art

[0002] Copper busbars are commonly used in electrical connection tools. Copper is one of the best conductors of heat and electricity and is the only metal that can be produced naturally in large quantities. Therefore, it is widely used in the electrical field due to its low cost and high electrical conductivity.

[0003] A Chinese patent with announcement number CN220856833U discloses a copper bar fixing bracket and a copper bar assembly, wherein the copper bar assembly comprises the copper bar fixing bracket and a copper bar; the copper bar is clamped in an open groove, and a stop protrusion limits the copper bar.

[0004] However, the copper busbar assembly is fixed with a copper busbar fixing bracket, which has the problems of poor stability and high production and assembly costs. Therefore, injection molded copper busbars came into being. However, injection molded copper busbars also have the problem of relative shaking of the copper busbar due to insufficient connection stability between the copper busbar and the injection molded part. In addition, since the copper busbar undergoes high temperature treatment of about 200°C during the injection molding process, the copper busbar under high temperature conditions reacts with oxygen in the air and forms an oxide film, thereby affecting the conductive properties of the injection molded copper busbar, which needs to be improved. Summary of the invention

[0007] Preferably: the connecting segment includes a head adapter portion connected to the rear side of the head connecting segment, a tail adapter portion connected to the rear side of the tail connecting segment, and a adapter connecting section connecting the head adapter portion and the tail adapter portion; the head connecting segment faces upward and the head adapter portion is located at the lower side of the head connecting segment; the tail connecting segment faces downward and the tail adapter portion is located at the upper side of the tail connecting segment.

[0008] Preferably, a positive angle connection portion facing upward is formed between the transition connection section and the head transition portion; and a negative angle connection portion facing downward is formed between the transition connection section and the tail transition portion.

[0009] Preferably: a head bending portion is provided between the head adapter portion and the head connecting segment, and the head bending portion is at a right angle; a tail bending portion is provided between the tail adapter portion and the tail connecting segment, and the tail bending portion is at a right angle; and the head connecting segment and the tail connecting segment are located on the same plane.

[0010] Preferably, the positive angle connection is greater than 90° and less than 180°, and the negative angle connection is less than or equal to 90°.

[0011] Preferably, the head connecting segment is provided with a head through hole, and the tail connecting segment is provided with a tail through hole.

[0012] It can be seen from the above scheme that the present application provides a high-temperature resistant pickled oxidized copper busbar, which has the following beneficial effects: the head connecting segment and the tail connecting segment facing the upper end and the lower end respectively are connected to each other by connecting segments, and then when the connecting segments are fixed by injection molding, the connection stability between the high-temperature resistant pickled oxidized copper busbar and the injection molded part will be significantly improved; at the same time, the pickling protective film plays a role in preventing the formation of an oxide film on the surface and thus affecting the conductive properties, so that the high-temperature resistant pickled oxidized copper busbar has the effect of stable connection and avoiding the decrease of conductive properties.

DETAILED DESCRIPTION

[0015] In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0016] It should be mentioned that the pickling protective film of the present application is obtained by chemical degreasing and water washing, and then surface pickling treatment. After the pickling protective film on the surface is formed by the pickling treatment, it is further washed with water and treated with a protective agent and dried in sequence to obtain the high-temperature resistant pickled oxidized copper busbar of the present application.

[0017] like Figure 1As shown, a high temperature resistant pickling oxidized copper busbar includes a head connector segment 1 and a tail connector segment 2. Both the head connector segment 1 and the tail connector segment 2 are used for conductive contact, thereby achieving efficient electrical conduction. The head connector segment 1 and the tail connector segment 2 are oriented toward the upper end and the lower end, respectively. In the embodiment of the present application, the head connector segment 1 is oriented directly upward, and the tail connector segment 2 is oriented toward the inclined lower right side, and the head connector segment 1 is located on the right side of the tail connector segment 2.

[0018] It should be mentioned that a connecting segment is provided between the head connecting segment 1 and the tail connecting segment 2. The connecting segment is fixed in the injection molded part by injection molding, thereby isolating oxygen and effectively avoiding the formation of surface oxidation film.

[0019] At the same time, the head connecting segment 1, the tail connecting segment 2 and the connecting segment are all provided with an acid pickling protective film on the outside. The acid pickling protective film has the effect of preventing the high temperature resistant acid pickling oxidized copper busbar from oxidizing and discoloring, thereby avoiding the reduction of the conductivity of the high temperature resistant acid pickling oxidized copper busbar.

[0020] like Figure 1 As shown, the connecting segment includes a head adapter portion 3 connected to the rear side of the head connecting segment 1, a tail adapter portion 5 connected to the rear side of the tail connecting segment 2, and a adapter connecting segment 4 connecting the head adapter portion 3 and the tail adapter portion 5. The head connecting segment 1 is oriented upward and the head adapter portion 3 is located at the lower side of the head connecting segment 1; the tail connecting segment 2 is oriented downward and the tail adapter portion 5 is located at the upper side of the tail connecting segment 2, so that when the injection molded copper bar workpiece is completed in cooperation with the injection molded part, a stable connection structure is formed between the high temperature pickling oxidized copper bar and the injection molded part, thereby avoiding the occurrence of relative shaking.

[0021] It should be noted that a positive angle joint 41 facing upward is formed between the transition connection section 4 and the head transition section 3, and a negative angle joint 42 facing downward is formed between the transition connection section 4 and the tail transition section 5. A head bending portion 11 is provided between the head transition section 3 and the head connection section 1, and the head bending portion 11 is at a right angle. A tail bending portion 21 is provided between the tail transition section 5 and the tail connection section 2, and the tail bending portion 21 is at a right angle.

[0022] At the same time, the head connector segment 1 and the tail connector segment 2 in the embodiment of the present application are located on the same plane. Therefore, a stable and effective electrical conduction effect is achieved by connecting the conductors separately through the head connector segment 1 and the tail connector segment 2. In order to further improve the stability of the connection structure between the high temperature pickling oxidized copper bar and the injection molded part, the positive angle connection 41 in the embodiment of the present application is greater than 90° and less than 180°, and the negative angle connection 42 is less than or equal to 90°. A head through hole 12 is provided in the head connector segment 1, and a tail through hole 22 is provided in the tail connector segment 2.

[0023] In summary, the present application provides a high-temperature resistant pickled oxidized copper busbar, which is interconnected by connecting segments through a head connecting segment 1 and a tail connecting segment 2 facing the upper end and the lower end respectively, and then when the connecting segments are fixed by injection molding, the connection stability between the high-temperature resistant pickled oxidized copper busbar and the injection molded part will be significantly improved; at the same time, the pickling protective film plays a role in preventing the formation of an oxide film on the surface and thus affecting the conductive properties, so that the high-temperature resistant pickled oxidized copper busbar has the effect of stable connection and avoiding the decrease of conductive properties.
