[0003] The most commonly used heating method in the vacuum evaporation coating machine currently used is electric heating, which evaporates the coating material through a resistively heated crucible.

[0004] At present, the evaporation of film materials often requires a long crucible. In order to achieve uniform heating during use, as many evenly dispersed resistance wires as possible are needed, which requires a large number of copper bars to connect the crucible.

[0005] However, when a large number of copper bars are used to connect the crucibles, the copper bars need to be connected to the wiring points of the crucibles. Due to the small wiring space, the copper bar connections often need to be movable during wiring, which makes the copper bars easy to break during installation, causing great inconvenience to the installation and maintenance of the equipment.

[0044] Example

[0045] The most commonly used heating method in vacuum evaporation coating machines currently used is electric heating, which evaporates the coating material through a resistive heating crucible. The evaporation of film materials often requires a long crucible. In order to achieve uniform heating during use, as many evenly dispersed resistance wires as possible are required, which requires a large number of copper bars to connect the crucible.

[0046] However, when a large number of copper bars are used to connect the crucibles, the copper bars need to be connected to the wiring points of the crucibles. Due to the small wiring space, the copper bar connections often need to be movable during wiring, which makes the copper bars easy to break during installation, causing great inconvenience to the installation and maintenance of the equipment.

[0047] To this end, this embodiment provides a conductive connecting member, such as Figures 1 to 3 As shown, it includes a strip-shaped conductive member, an end-connected conductive member 1 and a bent-connected conductive member 2. In this embodiment, the strip-shaped conductive member, the end-connected conductive member 1 and the bent-connected conductive member 2 are all made of copper.

[0048] In this embodiment, a plurality of the strip-shaped conductive members are connected at the ends to form a bent conductive body, and the end connecting conductive member 1 is connected to the end of the bent conductive body, and the end connecting conductive member 1 is suitable for connecting to the connection point of the crucible; wherein, Figure 4 As shown, the terminal connecting conductive member 1 is composed of a plurality of conductive sheets 5 stacked together, and both ends of all the conductive sheets 5 are formed by hot melting to form both ends of the terminal connecting conductive member 1 .

[0049] By configuring the end connecting conductive part 1 to be a plurality of stacked conductive sheets 5, the end connecting conductive part 1 will be appropriately bent and curved during the wiring process. Since the force of the stacked sheet parts is dispersed and the deflection resistance is enhanced, appropriate bending and curving will not cause the end connecting conductive part 1 to break and affect its use.

[0050] Specifically, Figure 2 FIG. 1 is a schematic diagram of the overall structure of the conductive connector in this embodiment. Figure 2 As shown, there are two strip-shaped conductive members in one conductive connecting member, which are named vertical row 3 and horizontal row 4 in this embodiment. The connection between the vertical row 3 and the horizontal row 4 is bent to form the bent conductive body. Figure 2 The middle upper end is used to connect with an external heating element, such as a resistance wire, and the vertical row 3 is Figure 2 The middle and lower ends are used to be fixed with the horizontal row 4. The lower ends of the vertical row 3 can be connected to the horizontal row 4 by rivets or other structures, and the angle between the two can be set as required. In this embodiment, the vertical row 3 and the horizontal row 4 are arranged perpendicularly.

[0051] Specifically, Figure 1 As shown, the vertical row 3 includes a vertical row body 31 and a connecting terminal 32. The lower end of the vertical row body 31 is connected to the horizontal row 4, and the connecting terminal 32 is connected to the other end of the vertical row body 31. The connecting terminal 32 is provided with a connecting hole (not shown in the figure). In this embodiment, the connecting hole is an L-shaped through hole. When installing, the vertical row 3 can be fixed to an external object by inserting a screw into the L-shaped through hole. The upper end of the connecting terminal 32 is fixed with a connecting resistance wire. In order to enhance conductivity and slow down oxidation, the end of the connecting and fixing resistance wire is made of graphite.

[0052] like Figure 3 As shown, in this embodiment, the length of the horizontal row 4 is greater than that of the vertical row 3. Specifically, the length of the horizontal row 4 is set according to the distance from the location to be connected to the conductive wiring, and the longest distance horizontal row 4 is set to connect the wiring device from the outermost end.

[0053] In this embodiment, a copper busbar structure is formed by arranging a plurality of independent conductive connectors, each of which includes a vertical row 3, a horizontal row 4, a bent connecting conductive member 2 and an end connecting conductive member 1. The conductive connectors are arranged to have different lengths, and the lengths and shapes of the vertical row 3, the horizontal row 4 and the bent connecting conductive member 2 are matched to adapt to the arrangement of copper busbars with different travels.

[0054] like Figure 3 The structure diagram of the end connection conductive member 1 in this embodiment is shown. Figure 3As shown, the end connecting conductive part 1 includes a transfer terminal 11, a wiring terminal 12 and a soft connecting section 13, the transfer terminal 11 is connected to the bending connecting conductive part 2, the wiring terminal 12 is connected to the wiring part of the crucible, and the soft connecting section 13 is connected between the transfer terminal 11 and the wiring terminal 12, wherein the transfer terminal 11 and the wiring terminal 12 are formed by hot-melt molding at both ends of all the conductive sheets 5.

[0055] Since the wiring space is small during use, a movable copper busbar connection is often required during wiring. Therefore, in this embodiment, the middle part of the terminal connecting conductive member 1 is configured as a soft connection to facilitate wiring and avoid breaking of the copper busbar during wiring.

[0056] Figure 1 FIG. 1 is a schematic diagram of the overall structure of the conductive connector in this embodiment when in use. Figure 1 As shown, the lengths of the end connection conductive member 1, the bent connection conductive member 2, the vertical row 3, and the horizontal row 4 in the conductive connectors at different positions are all different. It can be understood that this embodiment only provides an introduction to the overall structure of the conductive connector, and the specific lengths of each component can be changed according to the specific use environment, which is also included in the protection scope of this application. For example, Figure 1 In the figure, the conductive connector on the a side is farther from the external conductive wiring than the conductive connector on the b side, so the length of the horizontal row 4 of the conductive connector on the a side is greater than the length of the horizontal row 4 of the conductive connector on the b side. Similarly, the conductive connectors at the two ends of the a side and the b side are farther from the conductive wiring than the conductive connector in the middle, so a longer bending connecting conductive member 2 needs to be set.

[0057] Specifically, due to the use of the laminated intermediate soft connection section 13, proper bending and curving during the wiring process will not cause the copper busbar to break and affect its use. This is mainly because the stress of the laminated part is dispersed and the anti-bending is enhanced.

[0058] In this embodiment, the bending connection conductive member 2 is in a bending shape, and the bending connection conductive member 2 is connected between the bending conductive body and the terminal connection conductive member 1. The bending connection conductive member 2 is configured to have two ends with a fixed bending angle so as to achieve the transition between the horizontal row 4 and the terminal connection conductive member 1 below. In some embodiments, the bending connection conductive member 2 can be configured to be bent upward or downward.

[0059] The conductive connector provided in this embodiment is configured to have a multi-section structure to accommodate a long conductive stroke, and the end connecting conductive member 1 is configured to be a soft copper connection formed by welding copper laminations, thereby improving the toughness of the end connecting conductive member 1, thereby making the conductive connector less likely to break during installation.

[0060] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
