[0025] In related technologies, in the battery's output wiring harness structure, wire core leakage is prone to occur at the connection between the wire and the connector, which can easily cause a short circuit. In addition, the battery's output wiring harness structure is often in a bent state during use, which can easily cause the connection between the wire and the connector to break, which does not meet the UL2054 LISTED certification requirements.
[0026] In response to the above problems, embodiments of the present application provide a battery wiring harness structure and a battery, which can improve the stability and sealing of the connection between the wires and the connector.
[0027] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0028] Figure 1 1 is a schematic structural diagram of a wiring harness structure of a battery shown in an embodiment of the present application; Figure 2 It is a cross-sectional schematic diagram of the wiring harness structure of the battery shown in an embodiment of the present application.
[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a wiring harness structure for a battery, including a connector 1 , a wire 2 , a protective cover 3 and a first seal 4 .
[0030] One end of wire 2 is electrically connected to connector 1, and the other end of wire 2 is used to electrically connect to the battery. The battery cells in the battery are electrically connected to wire 2, and connector 1 can be used to electrically connect to an electrical device or a charging device. When connector 1 is electrically connected to an electrical device, the battery can supply power to the device through wire 2 and connector 1; when connector 1 is electrically connected to a charging device, the charging device can charge the battery through connector 1 and wire 2.
[0031] The protective cover 3 wraps around the wire 2 so that the wire 2 is not exposed outside the battery. The first seal 4 wraps around the connection between the wire 2 and the connector 1, sealing the connection between the connector 1 and the wire 2 to prevent the connection between the connector 1 and the wire 2 from contacting the external environment, thereby avoiding oxidation due to contact with air or short circuit due to contact with liquid. In the actual production process, the wire 2 and the connector 1 can be welded together first, and then the connection between the wire 2 and the connector 1 can be injection molded to form the first seal 4 at the connection between the wire 2 and the connector 1. After the first seal 4 is formed, the connection between the wire 2 and the connector 1 can be sealed and wrapped.
[0032] The first sealing member 4 also wraps one end of the protective sleeve 3 , so that the protective sleeve 3 is sealed at the end close to the connector 1 , so that the entire wire 2 is not exposed to the outside, thereby enhancing the protection of the wire 2 .
[0033] Based on the above solution, by arranging the first seal 4 at the connection between the connector 1 and the wire 2, the first seal 4 wraps the connection between the connector 1 and the wire 2, thereby protecting and sealing the connection between the connector 1 and the wire 2, and preventing the metal wire core in the wire 2 from leaking out at the connection with the connector 1. The first seal 4 can also improve the extrusion resistance of the connector 1 and the wire 2, and prevent the connection between the wire 2 and the connector 1 from being bent and disconnected due to external force. The protective cover 3 wraps the wire 2, thereby preventing the wire 2 from being exposed, so that the battery with a wiring harness structure can meet the UL2054-LISTED certification requirements.
[0034] In some embodiments, the first seal 4 is made of a plastic material and is block-shaped. Specifically, the first seal 4 can be injection molded at the connection between the connector 1 and the wire 2, and wrapped around the connection between the connector 1 and the wire 2 and one end of the protective cover 3, so that the first seal 4 is sealed to the connection between the connector 1 and the wire 2 and one end of the protective cover 3. This molding method provides good sealing performance and a secure connection. The first seal 4 is made of a plastic material, which provides good sealing performance while maintaining a certain degree of flexibility, suitable for daily use of the wiring harness structure.
[0035] In some embodiments, as Figure 1 and Figure 2 As shown, there are multiple wires 2, for example, three wires, and the protective cover 3 wraps the multiple wires 2, that is, the multiple wires 2 are all located in the protective cover 3, and the first seal 4 simultaneously seals the connection between the multiple wires 2 and the connector 1.
[0036] In some embodiments, as Figure 2 As shown, the end of connector 1 near wire 2 and the end of wire 2 near connector 1 are both embedded within first seal 4, which improves the secure connection between first seal 4, connector 1, and wire 2, and enhances the bending resistance of the connection between connector 1 and wire 2. The internal length of first seal 4 can be appropriately longer, and it wraps around the end of protective cover 3, ensuring a sealed connection between protective cover 3, wire 2, and connector 1.
[0037] In some embodiments, protective cover 3 is made of a thermoplastic elastomer, such as a heat shrink tubing, such as V-0, TPE, or a sleeve. Protective cover 3 is impact- and scratch-resistant, protecting wire 2 and ensuring it meets the UL2054 LISTED constant-force extrusion test requirements. Protective cover 3 and wire 2 are flexible and bendable.
[0038] In the related art, since the wire cannot be effectively fixed on the battery's plastic frame, it is easy to slip and loosen. In order to ensure that the wire 2 is stably connected to the battery's plastic frame, as shown in the following example: Figure 1 and Figure 2 As shown, in some embodiments of the present application, the wiring harness structure further includes a second seal 5, which is wrapped around the wire 2, and the wire 2 passes through the second seal 5. By sealing the second seal 5 at the opening on the battery rubber frame for passing the wire 2, the wire 2 can be stably fixed to the battery rubber frame to prevent the wire 2 from sliding or loosening. At the same time, the second seal 5 blocks and seals the opening of the battery rubber frame to prevent liquid from entering the rubber frame and prevent damage to the components inside the rubber frame. The wire 2 passes through the second seal 5, and the end of the wire 2 extending into the rubber frame is electrically connected to the battery cell.
[0039] In some embodiments, the wire 2 can be first electrically connected to the battery cell in the battery plastic frame, and then the opening on the battery plastic frame for passing the wire 2 can be injection molded to form a second seal 5 at the opening, so that the second seal 5 fills the opening of the plastic frame. After the second seal 5 is formed, it is fixed to the plastic frame and the wire 2 respectively, so that the wire 2 is fixed relative to the plastic frame while also sealing the opening to ensure the sealing of the battery. In some embodiments, the second seal 5 can be first injection molded on the wire 2 to form the second seal 5, and then the second seal 5 is installed in the opening of the battery plastic frame, so that the second seal 5 blocks the opening. The second seal 5 can be made of plastic material, so that the second seal 5 has good sealing performance and a certain degree of flexibility, which is suitable for daily use of the wiring harness structure.
[0040] In some embodiments, the second seal 5 wraps the end of the protective cover 3 away from the first seal 4, so that the end of the protective cover 3 can be sealed. The first seal 4 and the second seal 5 seal both ends of the protective cover 3, so that the entire wire 2 located outside the battery plastic frame is in a sealed state, ensuring that the wire 2 is not in contact with the external environment, and the entire wire 2 has anti-extrusion properties.
[0041] In some embodiments, as Figure 1 and Figure 2 As shown, the surface of the second seal 5 is provided with a sealing groove 51 opened along the circumference of the second seal 5. The sealing groove 51 can be snapped into the corresponding structure on the battery plastic frame to ensure that the second seal 5 and the plastic frame are firmly connected and prevent the second seal 5 from falling off the plastic frame.
[0042] An embodiment of the present application also provides a battery, including the wiring harness structure of the battery as described in the above embodiment, so that the battery meets the UL2054 LISTED certification requirements.
