AI Technical Summary
In existing output connectors, the connection point between the wire and the metal plug is prone to severe overheating under high current, which can lead to the melting of the insulation material. Furthermore, the existing heat dissipation structure has a slow response speed and cannot alleviate short-term overheating in a timely manner.
The wires are divided into multiple strands of conductor metal wires, which are then soldered to different points on the plug to form multiple connection points. Heat sinks are placed near the solder points to disperse the current and accelerate heat dissipation.
By dispersing current and accelerating heat dissipation, the heat generation at individual connection points is reduced, insulation material melting is avoided, service life is extended, and current carrying capacity is improved.

[0033] The connection structure of the cable conductor provided by the embodiments of the present application can be used as the end connection structure of various circuit components, for example, the busbar is used as the conductor of the cable conductor, the cable is used as the wire of the cable conductor, and the cable wire is divided into multiple metal wires, which are connected to different positions of the conductor of the busbar respectively.
[0034] The connection mode between the wire and the conductor in this paper can be welding, riveting and other connection modes that can form electrical connection between the wire and the conductor.
[0035] In this paper, the output connector is taken as an example, the plug is taken as the conductor of the cable conductor, the wire is welded with the plug, and the embodiments of the present application are described.
[0036] Please refer to Figures 1-2The embodiment of the present application provides an output connector 1, which comprises a plug 12 and a wire 11, the wire 11 is welded to the plug 12, and the wire 11 comprises at least a first conductor wire 111 and a second conductor wire 113; the first conductor wire 111 is welded to the plug 12 and a first welding point 112 is formed on the plug 12, the second conductor wire 113 is welded to the plug 12 and a second welding point 114 is formed on the plug 12, and the first welding point 112 and the second welding point 114 are not overlapped.
[0037] Preferably, the output connector 1 further comprises a shell 13, the plug 12 is fixed to the shell 13, and a part of the plug 12 is located inside the shell 13 and welded to the wire 11, and another part of the plug 12 is located outside the shell 13 and used for connecting with an external terminal device and electrically connected with the external terminal device.
[0038] The wire 11 can be divided into two parts to form the first conductor wire 111 and the second conductor wire 113, which are welded to different positions of the plug 12 respectively to form the structure in the first aspect of the present application. Figure 1 The wire 11 can be divided into more than two parts to form the first conductor wire, the second conductor wire and the third conductor wire, which are welded to different positions of the plug 12 respectively.
[0039] After the wire 11 is divided into multiple conductor wires and the multiple conductor wires are welded to the plug 12 respectively, the heat generated by a single welding point of the wire 11 can be compared with the heat generated by a welding point of a wire in the prior art by using the Joule heat formula P=I2R.
[0040] For example, the wire 11 is evenly divided into the first conductor wire 111 and the second conductor wire 113, then the single-loop resistance is increased by 1 times, the current is reduced to 1 / 2, the single-loop heat power P is reduced to 1 / 2, and the single-loop heat can be reduced, so that the heat generation degree of a single connection point is reduced, and the melting loss of the outer insulation material of the wire is avoided.
[0041] By dividing the wire 11 into multiple conductor wires and welding the multiple conductor wires to the plug 12 respectively, multiple loops can be formed to reduce the single-loop heat and achieve the heat distribution effect by dispersing the current, so that the wire 11 and the plug 12 can carry larger current, the surrounding elements of the loop are effectively protected, and the service life of the wire 11 and the plug 12 is prolonged.
[0042] Preferably, the first conductor wire 111 and the second conductor wire 113 comprise equal amounts of conductor wires, so that the heat generated at the first welding point 113 and the second welding point 114 is uniform.
[0043] Further, on the heat dissipation structure, preferably, the output connector 1 further comprises a heat sink, the heat sink is arranged inside the shell 13 and is arranged close to the first welding point 112 and the second welding point 114, so as to timely transfer the heat at the first welding point 112 and the second welding point 114 to the heat sink.
[0044] Figure 2 FIG. 4 is a top view of the output connector 1, Figure 2 The dashed box is used to represent the heat sink, as shown in Figure 2 As shown, the heat sink comprises a heat sink plate, the heat sink plate is attached to the inner wall of the shell 13, and the plug 12 is at least partially attached to the heat sink plate; the wire 11 comprises a first group of conductor wires 111 and a second group of conductor wires 113, and the first group of conductor wires 111 and the second group of conductor wires 113 each comprise a plurality of conductor wires; the bottom of the plug 12 is attached to the heat sink plate, and the first welding point 112 and the second welding point 114 are respectively arranged on the opposite sides of the plug 12, so as to improve the heat dissipation effect of the heat sink.
[0045] The embodiment of the present application welds the first group of conductor wires 111 of the wire 11 to the conductor to form the first welding point 112, welds the second group of conductor wires 113 of the wire 11 to the conductor to form the second welding point 114, and the first welding point 112 and the second welding point 114 do not overlap, so as to reduce the heat generation of the single welding point at the connection between the wire 11 and the conductor, alleviate the heat generation degree at the single welding point, and avoid the melting loss of the outer insulation material of the wire.
