[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components.

[0025] Figure 1 This is a schematic structural diagram of a connector in one embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 3, an embodiment of the present invention provides a connector 100, which is configured to be conductive; the connector 100 includes a first connecting piece 110, a second connecting piece 120 and a third connecting piece 130, the first connecting piece 110 and the third connecting piece 130 are spaced apart along the thickness direction of the third connecting piece 130, the two ends of the second connecting piece 120 are respectively connected to the first connecting piece 110 and the third connecting piece 130, the first connecting piece 110 and the third connecting piece 130 are enclosed to form a clamping groove 140, and the clamping groove 140 is used to clamp the outer shell of the battery assembly; there are at least two third connecting pieces 130, and at least two third connecting pieces 130 are spaced apart along the width direction thereof, and the third connecting piece 130 is used to abut against the circuit board 400.

[0026] During use, the embodiment of the present invention clamps the connector 100 onto the housing, electrically connecting the first connector 110 to the battery within the housing. The third connector 130 is located outside the housing and connected to the circuit board 400. This allows the battery and circuit board 400 to be electrically connected via the connector 100, simplifying operation and reducing assembly difficulty. Furthermore, since at least two third connectors 130 are connected to the circuit board 400, the contact area between the third connectors 130 and the circuit board 400 is increased, thereby avoiding the situations where a single third connector 130 would result in an insufficient contact area, excessive current, and contactor overheating.

[0027] In one embodiment of the present invention, each of the third connecting pieces 130 is provided with a protrusion 131, which is located on the side of the third connecting piece 130 facing away from the first connecting piece 110. Due to the provision of the protrusion 131, the third connecting piece 130 does not need to be tightly fitted with the circuit board 400; instead, the protrusion 131 only needs to abut against the circuit board 400, thus avoiding interference with the arrangement of other components on the circuit board 400. However, at the same time, the contact area between the protrusion 131 and the circuit board 400 is small. If there is a deviation in the processing or assembly of the connector 100, it is easy for the protrusion 131 to only contact the circuit board 400 at a single point, resulting in a situation where the contact area is too small, the current is too high, and the contactor overheats. To this end, the present invention is provided with at least two third connecting pieces 130 to increase the reliability of the contact between the connector 100 and the circuit board 400 and reduce the risk of poor contact.

[0028] Furthermore, the projection of the protrusion 131 along the width of the third connecting piece 130 is arc-shaped, giving the entire protrusion 131 a circular arc-shaped sheet structure. This is elastic, so that when used, the connector 100 is squeezed and elastically deformed, increasing the contact area between the protrusion 131 and the circuit board 400 and preventing the protrusion 131 from disconnecting from the circuit board 400. Furthermore, the protrusion 131 and the third connecting piece 130 are integrally bent and formed, without any additional connection structure, thus avoiding operational failures caused by loose connections.

[0029] In one embodiment of the present invention, each of the third connecting pieces 130 is provided with an inserting piece 132. The inserting piece 132 is located on the side of the third connecting piece 130 facing the first connecting piece 110 and extends toward the first connecting piece 110. Specifically, the inserting piece 132 is formed by bending one end of the third connecting piece 130 away from the second connecting piece 120 toward the first connecting piece 110. When the connector 100 is clamped on the housing, the inserting piece 132 can be plugged into the housing, thereby achieving the purpose of fixing the connector 100 to the housing, preventing the housing from detaching from the clamping groove 140, and improving the clamping stability.

[0030] In one embodiment of the present invention, the distance between two adjacent third connecting pieces 130 is smaller than the width of the third connecting piece 130. Since the total width of the connector 100 is limited, minimizing the distance between two adjacent third connecting pieces 130 can increase the width of the third connecting piece 130 and improve the contact area between the third connecting piece 130 and the circuit board 400.

[0031] like Figure 2 As shown, an embodiment of the present invention also provides a battery assembly, including a shell, a battery and a connector 100 as in any of the above embodiments, so as to have all the effects of the connector 100; the shell includes a first shell 200 and a second shell 300, and the clamping groove 140 is clamped on the first shell 200; the second shell 300 is connected to the first shell 200 to form a battery cavity for accommodating the battery, and the first connecting piece 110 is located in the battery cavity and is electrically connected to the battery.

[0032] Furthermore, the third connecting piece 130 is provided with a plug-in piece 132 extending toward the first connecting piece 110; a plug-in slot 210 is provided on the side of the first shell 200 facing away from the second shell 300; the plug-in piece 132 is plugged into the plug-in slot 210, thereby achieving the purpose of fixing the connector 100 on the shell, preventing the shell from detaching from the clamping slot 140, and improving the stability of the clamping.

[0033] like Figure 3 As shown, an embodiment of the present invention further provides an in-vehicle T-BOX device, comprising a circuit board 400 and a connector 100 or a battery assembly as described in any of the above embodiments, so as to have all the effects of the connector 100 or the battery assembly; the connector 100 abuts against the conductive connector of the circuit board 400. The conductive connector can be copper foil, nickel-plated copper foil, gold-plated copper foil, or gold foil.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
