Technical Field

[0001] The utility model belongs to the technical field of double-end connectors, in particular to a double-end center-line battery connector. Background Art

[0002] In order to facilitate customers to test battery packs in the current market, it is necessary to set a neutral output line on the middle battery terminal of the battery pack, so that group detection of the battery pack can be realized. In actual use, the connecting line is composed of a cable and a copper nose. When it is necessary to add a neutral output line, the battery terminal in the middle needs to be connected to the copper nose of the battery connecting line and the copper nose of the neutral output line at the same time, and then fixed with bolts. This installation method with two copper noses tightly pressed up and down has the risk of poor contact and heating of the copper nose. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0025] This application proposes a double-ended centerline battery connector. Figure 1 A schematic diagram of the structure of a double-ended centerline battery connector is shown; Figure 1 In the embodiment, the double-ended center line battery connector includes:

[0026] The flat portion 100 has a through hole 110 formed therein;

[0027] Two sets of connection parts 200, the two sets of connection parts 200 are respectively connected to the two ends of the flat part 100, and one end of the connection part 200 away from the flat part 100 is an open end;

[0028] The flat portion 100 and the two sets of wiring portions 200 are integrally pressed and formed;

[0029] The lower surface of the flat portion 100 is flush with the lower edge of the wiring portion 200 .

[0030] The traditional single-head copper nose is changed to an integrally pressed double-head copper nose for connection. The two wiring parts 200 can be connected to the battery connecting line and the neutral output line respectively. The bolts can pass through the through hole 110 to press and fix the flat part 100, changing the traditional installation method of two stacked copper noses to eliminate the hidden danger of poor contact. At the same time, after the device is installed, the flat part 100 can form a support for the wiring part 200, changing the traditional structural design of the flat part 100 being set in the middle of the wiring part 200 to avoid the wiring part 200 from warping up after installation.

[0031] It should be noted that the shape of the flat portion 100 can be designed as required to change the position between the two connecting portions 200. For example, Figure 2 shows a schematic diagram of a deformed structure of the flat portion 100; Figure 2 In the figure, the two connection parts 200 have the same opening direction, are arranged side by side, and the flat part 100 is designed as a semicircular ring; it should be noted that the shape of the flat part 100 and the positions of the two connection parts 200 are not limitations thereto.

[0032] Figure 3 shows a schematic structural diagram of the rib 210; Figure 3 In the figure, the outer wall of the wiring part 200 is provided with ribs 210, and the thickness of the ribs 210 gradually increases along the insertion direction of the wire body.

[0033] like Figure 3 As shown in the figure, the entry direction of the wire body is shown. During installation, the wire body is usually inserted into the wiring part 200, and the outer hose of the wire body is sleeved on the outside of the wiring part 200. Through the setting of the rib 210, a barb-like structure can be formed to increase the resistance of the hose from the wiring part 200, thereby improving the connection effect between the hose and the wiring part 200.

[0034] Continue to see Figure 3 The rib 210 has a corner 211 on one side away from the wiring portion 200 , and the corner 211 is an arc-shaped structure.

[0035] The design of the corner 211 ensures that the resistance provided when the hose is detached is sufficient. Meanwhile, the arc-shaped structure can avoid cutting the hose and increase the contact surface with the inner wall of the hose.

[0036] Continue to see Figure 3 Along the length direction of the connection portion 200, multiple groups of ribs 210 are arranged at intervals to form barb groups.

[0037] The multiple groups of ribs 210 are arranged at intervals, and sufficient space is reserved to ensure that the shrinkage force of the hose itself can fit the outer wall of the wiring portion 200.

[0038] Continue to see Figure 3 There are multiple groups of barb groups, which are evenly distributed around the wire portion 200.

[0039] Figure 4 A schematic structural diagram of the vertical needle group 220 is shown; Figure 4 In the figure, a non-return assembly is arranged in the wiring part 200, and the non-return assembly includes two groups of vertical needle groups 220. The vertical needle groups 220 include multiple groups of vertical needles 221 evenly distributed along the length direction of the wiring part 200, and the two groups of vertical needle groups 220 are staggered.

[0040] Through the staggered arrangement of vertical needles 221, when the wire is inserted into the vertical needle group 220, it will be restricted by the vertical needles 221 to change the direction of movement to form a wavy motion trajectory. Therefore, when the wire is pulled away from the wiring part 200, static friction occurs between the wire and the vertical needles 221, thereby preventing the wire from escaping from the vertical needle group 220.

[0041] Continue to see Figure 4 There are multiple groups of anti-return components, which are evenly distributed around the axis of the wiring part 200.

[0042] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
