Detailed Description

Embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the same reference numerals may be used in the drawings for similar components or functional elements. The accompanying drawings are only intended to illustrate embodiments of the present disclosure. Those skilled in the art will recognize that alternative embodiments can be made from the following description without departing from the spirit and scope of the disclosure.

The structure of the plug-in bus bar and the associated conductor arrangement of the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings. It should be understood that although the embodiments of the present disclosure are described with respect to a plug-in bus for ac power, the concepts of the present disclosure may also be used with a plug-in bus for dc power.

Fig. 1 and 2 show an overall structural view of a plug-in bus bar of an embodiment of the present disclosure. In contrast to fig. 1, fig. 2 has the protective cover removed and the plug-in mouth of the plug-in bus bar has been exposed. As shown in fig. 1 and 2, the plug-in bus bar 1 comprises a plurality of conductor arrangements 10 and a cover plate. The cover plate is arranged around the conductor arrangement 10 to protect the conductor arrangement 10. In the illustrated embodiment of a plug bus for alternating current, the plug bus 1 can comprise four conductor arrangements 10. In other alternating-current plug bus embodiments, the plug bus 1 can comprise three conductor arrangements 10. In some embodiments of a plug-in bus for direct current, the plug-in bus 1 may comprise two conductor arrangements 10, for example. The cover plate may be implemented in various forms. In some embodiments, the cover plates may include an upper cover plate 30, a lower cover plate 60, and a side cover plate 40. The side cover 40 may include a socket, for example, a power take-out prong (see fig. 3) of a power take-out box (not shown) may be adapted to take power from the socket. It should be understood that the illustrated cover plate configuration is merely exemplary. Since these structures belong to the structures well known in the art, detailed description thereof is omitted.

Fig. 3 shows a schematic structural diagram of the conductor device 10 and the power taking pawl 70 according to the embodiment of the present disclosure. As shown in fig. 3, the tap 14 of the conductor arrangement 10 may engage with the current take out claw 70. Whereby the power take-out prong 70 is able to take power from the conductor arrangement.

The following describes a schematic structural diagram of a conductor device according to an embodiment of the present disclosure in detail with reference to fig. 4 to 5. As shown in fig. 4, the conductor arrangement 10 may include a conductor body 12 and a tap 14. The conductor body 12 may transmit power from a power source. In some embodiments, the conductor body 12 is made of a good electrically conductive aluminum material. In other embodiments, the conductor body 12 may be made of copper material, although this would increase the cost of the conductor arrangement. In the illustrated embodiment, the conductor body 12 may be formed in sheet form. It should be understood that this is merely exemplary.

The tap 14 is attached to the conductor body 12. As shown in fig. 5, the tap 14 may include a tap body 142 and a tap region 144. In some embodiments, the tap body 142 is made of aluminum. The connector region 144 may at least partially cover an outer surface of the tap body 142.

The joint region 144 may comprise a bimetallic material in accordance with embodiments of the present disclosure. In the case where the conductor body 12 is made of an aluminum material having good electrical conductivity and the tap body 142 is made of an aluminum material, the tap region 144 may include an aluminum-copper material composite. By the bimetal material of the joint region, when the power taking pawl 70 is matched with the joint region, the contact resistance between the power taking pawl 70 and the tap 14 can be reduced, thereby improving the heat conduction efficiency and reducing the temperature rise and the cost of the product.

In some embodiments, the copper-aluminum material may comprise a copper-aluminum material layer. For example, the copper-aluminum material may be formed as a layered structure. The copper-aluminum material layer may include an aluminum layer abutting the outer surface of the joint body 142 and a copper layer disposed away from the outer surface. The copper layer may be disposed as an outer layer of the copper-aluminum material layer and may be in electrical contact with the current-drawing tab 70. In this case, it is possible to further reduce the contact resistance between the power take-out claw and the tap 14 to further improve the heat conduction efficiency. In some embodiments, the surface of the copper layer further comprises at least one of: a silver plated layer or a tin plated layer. This can further improve the heat transfer efficiency.

As shown in fig. 5, the tap 14 may include a first end 146 attached to the conductor body 12 and a second end 148 opposite the first end 146. The tap 14 may extend from the first end 146 toward the second end 148. In the illustrated embodiment, the tap 14 is formed in a sheet shape extending from the first end 146 toward the second end 148. Therefore, the contact area between the power taking plug claw and the power taking plug claw can be increased, the power taking efficiency and the heat dissipation performance are ensured, and the joint strength between the power taking plug claw and the tap joint is ensured.

In some embodiments, the tap 14 is attached to the conductor body 12 at the first end 146 by friction stir welding or argon arc welding. The attachment strength of the tap 14 to the conductor main body 12 can be ensured by this attachment.

In some embodiments, the copper-aluminum material is attached to the outer surface of tap body 142 near second end 148 by resistance welding. With this point contact attachment, not only can the attachment strength requirements of the copper-aluminum material with the tap body 142 be satisfied, but also the heat dissipation performance between the copper-aluminum material and the tap body can be improved.

In the illustrated embodiment, the copper-aluminum material is configured to: one end of the tap body 142 is at least partially covered in a substantially U-shaped configuration when viewed from the side of the extending direction of the tap 14. With this structure, the attachment of the copper-aluminum material to the tap body 142 may be facilitated. It will be appreciated that this is merely exemplary and that other suitable shapes may be used.

Fig. 6 and 7 show other exemplary structural schematics of the tap 14 of the present disclosure. In the embodiment of the tap 14 shown in fig. 5, the tap body 142 may have a substantially uniform thickness. Unlike fig. 5, in the embodiment shown in fig. 6 and 7, the tap 14 is formed to have different thicknesses according to positions. Thereby, the tap 14 may be enabled to match the thickness of the conductor body 12 and/or the thickness of the current extraction prong 70.

In some embodiments, as shown in fig. 7, the thickness of the tap 14 at the connection portion adjacent the conductor body 12 may be greater than the thickness of the tap 14 at the connector region 144. This structure is particularly suitable in the case where the thickness of the conductor body 12 is thick. In some embodiments, as shown in fig. 7, the thickness of the tap 14 at a portion adjacent the conductor body 12 is less than the thickness of the tap 14 at the connector region 144. This structure is particularly suitable in the case where the thickness of the conductor main body 12 is thin. It should be understood that the illustrated construction is merely exemplary and that the tap 14 may be formed of other suitable thicknesses in light of the teachings of the present disclosure.

Those skilled in the art will understand that: the foregoing description is provided for the purpose of illustration and not limitation. It will be apparent to one skilled in the art that the present invention may be practiced in other implementations that depart from these specific details. Moreover, unnecessary detail of known functions and structures may be omitted from the current description so as not to obscure the present invention.

Although specific embodiments have been illustrated and described herein, those of ordinary skill in the art appreciate that any arrangement which is calculated to achieve the same purpose may be substituted for the specific embodiments shown and that the utility model has other applications in other environments.
