[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Please refer to Figure 1-5 As shown, a multi-contact busbar connector includes a shell 1, in which a first clip 2 and a second clip 3 are inserted, and the first clip 2 and the second clip 3 are arranged relatively parallel; wherein the first clip 2 and the second clip 3 are respectively provided with an arc-shaped first protrusion 4 and a second protrusion 5; the first protrusion 4 is placed above the second protrusion 5, and the opening radius of the first protrusion 4 is smaller than the opening radius of the second protrusion 5.

[0025] Specifically, arc-shaped first and second protrusions are provided on the first clip and the second clip on both sides, and the opening radius of the first protrusion is smaller than the opening radius of the second protrusion; the clips on both sides cooperate with each other to present a symmetrical structure, and the first clip and the second clip are assembled and loaded into the shell to complete the assembly, and the first and second protrusions are stamped out on the first clip and the second clip, and the arc radius of the first protrusion at the mouth is smaller, so that the insertion force is smaller when the copper busbar is inserted, and the arc radius of the second protrusion at the bottom is larger, so that when the copper busbar is removed between the first clip and the second clip, the copper busbar can obtain a greater product retention force and improve the contact reliability; and under the same conditions, the first clip and the second clip have better contact with the copper busbar, which will make the overall contact impedance lower and the temperature rise lower, thereby obtaining higher energy transmission.

[0026] In this embodiment, both the first clamping piece 2 and the second clamping piece 3 are provided with an opening groove 6 , and a stamped spring piece 7 is provided in the opening groove 6 . The stamped spring piece 7 is disposed between the first protruding portion 4 and the second protruding portion 5 .

[0027] Specifically, between the first protrusion and the second protrusion, a plurality of stamped spring sheets are stamped, and the stamped spring sheets have resilience. When the copper bar is inserted, the stamped spring sheets can also contact the copper bar. After a plurality of stamped spring sheets are stamped out on the first clip and the second clip, the overall connection width is narrower, which can reduce the insertion force of the copper bar, and at the same time increase the contact surface between the copper bar and the clips on both sides, so that the overall contact impedance is lower and the temperature rise is lower, thereby obtaining higher energy transmission.

[0028] In this embodiment, the first clamping piece 2 and the second clamping piece 3 are placed in a spring clip 8, and the spring clip 8 is in a "U" shape.

[0029] Specifically, the first clip and the second clip cooperate with each other to form a symmetrical structure. After assembly, the outer layer is assembled with a spring clip, the two clips are clamped in the spring clip, and then they are installed in the outer shell to complete the assembly. The "U"-shaped spring clip is used to make the assembly between the first clip and the second clip more stable, which can prevent the first clip and the second clip from being displaced, resulting in poor contact with the copper busbar.

[0030] In this embodiment, the lower end of the first clip 2 is bent upward and extended to form a first elastic portion 9 , and the lower end of the second clip 3 is bent upward and extended to form a second elastic portion 10 .

[0031] Specifically, the first elastic part and the second elastic part utilize their own squeezing and rebounding effects to make the first clip and the second clip be placed in the spring clip clip more stably.

[0032] In this embodiment, a first fixing portion 11 and a second fixing portion 12 are respectively disposed on the sides of the first elastic portion 9 and the second elastic portion 10 .

[0033] Specifically, fixing holes for fixing are provided on the first fixing portion and the second fixing portion, and the first fixing portion and the second fixing portion are used to fix the entire connector.

[0034] In this embodiment, a first plug-in portion 13 is provided at the end of the first elastic portion 9 opposite to the first fixed portion 11, and a first slot 14 is provided on the inner wall of the shell 1 for use with the first plug-in portion 13; a second plug-in portion 15 is provided at the end of the second elastic portion 10 opposite to the second fixed portion 12, and a second slot 16 is provided parallel to the first slot 14 for use with the second plug-in portion 15.

[0035] Specifically, the outer ends of the shell are designed with openings. When the first clip, the second clip and the shell are assembled, the first clip and the second clip can be inserted into the lower end of the shell, and the first plug-in parts and the second plug-in parts on the two clips are respectively matched with the first slot and the second slot on the shell, so that the first clip and the second clip are fixed in the shell.

[0036] In this embodiment, a clamping groove 17 is disposed at the lower end of each of the first elastic portion 9 and the second elastic portion 10 , and a clamping hook 18 fixedly matched with the clamping groove 17 is disposed at a side of the housing 1 .

[0037] Specifically, after the first clip and the second clip are placed in the housing, the slots on the two clips cooperate with the hooks on the housing so that the hooks are hooked in the slots to prevent the first clip and the second clip from sliding downward and detaching from the housing, making the connection more stable.

[0038] In this embodiment, through holes 19 are formed on both sides of the spring clip 8 , and inwardly inclined abutment portions 20 are formed in the through holes 19 .

[0039] Specifically, the abutting parts in the through holes on both sides of the spring clip abut against the upper edges of the first elastic part and the second elastic part, which can prevent the first clip and the second clip from being over-inserted into the shell, so that the upper ends of the first clip and the second clip are exposed from the upper end of the shell.

[0040] In this embodiment, a clamping portion 21 is provided at the end of the opening of the spring clip 8 extending toward the center.

[0041] Specifically, the clamping portion at the upper end of the spring clip can reduce the opening width of the spring clip, so that after the copper bar is inserted between the first clip and the second clip, it is not easy to move or detach outward.

[0042] In this embodiment, a first baffle 22 and a second baffle 23 are respectively disposed on the sides of the first clamping piece 2 and the second clamping piece 3 .

[0043] Specifically, the first baffle plate and the second baffle plate are arranged opposite to each other, so that after the copper bar is inserted between the first clamping piece and the second clamping piece, it is not easy to shake left and right, so that the contact is more stable.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
