It should be understood that the number of cantilevers 20 may also be other values and is not limited to the above.
In one embodiment, the two ends of the substrate first sidewall 101 and the substrate second sidewall 102 in the substrate through hole 100 are respectively connected by the substrate third sidewall 103 and the substrate fourth sidewall 104, the substrate third sidewall 103 and the substrate fourth sidewall 104 are both arc-shaped, and the cantilever 20 is not connected to the substrate third sidewall 103 and the substrate fourth sidewall 104.

The shape of the substrate 10 is preferably circular, but the shape may be designed according to actual needs, for example, the shape may be rectangular, and the like, and is not limited herein.
In one embodiment, the supporting portion 202 of the cantilever 20 in the single-sided conductive spring is used for elastically abutting against the conductive member, and the side of the single-sided conductive spring, where the cantilever 20 is not disposed, is used for connecting (either fixedly or detachably) with the external conductive member. The working principle of the single-sided conductive elastic sheet can be as follows:
the position of the single-sided conductive elastic sheet is fixed, so that the cantilever 20 faces the conductive part needing to be conductive, and the side of the single-sided conductive elastic sheet, which is not provided with the cantilever 20, is communicated with the external conductive part.
When the conductive part needs to be communicated with an external conductive part, the conductive part is contacted with the cantilever 20 and presses the cantilever 20, so that the cantilever 20 moves towards the plane of the base body 10, the supporting part 202 deforms in the process, one end of the connecting part 201 connected with the supporting part 202 moves along with the movement of the supporting part 202, the conductive part is elastically abutted against the cantilever 20 at the moment, the external conductive part is connected with the base body 10, and the cantilever 20 is connected with the base body 10, so that the conductive part is ensured to be safely and reliably communicated with the external conductive part through a single-side conductive elastic sheet.
When it is no longer necessary to bring the conductive member into contact with the external conductive member, the conductive member is removed, the cantilever 20 is no longer pressed by the conductive member, and the support portion 202 is returned away from the base 10.
In one embodiment, the single-sided conductive tab may be used in a battery compartment, where the conductive component may be a battery, such as a new energy battery, and the external conductive component may be a copper plate or a conductive circuit board, etc. When the battery needs to be connected with the external conductive part, the battery is contacted with the cantilever 20 and presses the cantilever 20, so that the cantilever 20 moves towards the plane of the base ring 10, wherein the supporting part 202 is pressed to move towards the plane of the base ring 10, and the battery is electrically connected with the external conductive part through the single-sided conductive elastic sheet. When it is no longer necessary to connect the battery to an external conductive member, the battery is removed and the cantilever 20 is no longer squeezed by the battery and the support 202 returns in a direction away from the base ring 10. It should be understood that the single-sided conductive elastic sheet may also be applied to other products, for example, electronic products, and the working principle thereof is similar to the above principle, and is not described herein again.
The beneficial effect of the conductive shell fragment of single face that this embodiment provided lies in: as the cantilever 20 capable of being elastically compressed is arranged on one side of the plane where the substrate 10 is located, the single-side conductive elastic sheet can be elastically abutted against the conductive part in the using process, so that the conductive part and the external conductive part can be more tightly connected, and the conductive connection performance is more stable. And the cantilevers 20 are arranged oppositely in two rows, when the conductive part of the conductive part is in a rectangular or similar rectangular structure, the cantilevers 20 arranged oppositely in two rows are stressed more uniformly in the contact process with the conductive part, the contact effect is better, and therefore the conductive effect is better.

It should be understood that the width of the gap L1 can be set as required, and is not limited herein.
Referring to fig. 5 to 8, in an embodiment, the width of the supporting portion 202 is not the same everywhere, and the width of the supporting portion 202 is gradually reduced from a side close to the connecting portion 201 to a side away from the connecting portion 201, so that on one hand, the supporting portion 202 can be ensured to be in close contact with the conductive member when elastically abutted, and on the other hand, the distance between the ends of the supporting portion 202 is also ensured to be increased, and the supporting portion 202 does not contact with each other during moving toward the base 10, thereby further avoiding mutual influence.

The curvature of the arc contact surface can be designed according to the needs, and is not limited here.
Referring to fig. 9 to 12, in an embodiment, the end of the deformation portion 204 extends toward the plane of the substrate 10, and during the elastic abutting process, the arc contact surface of the arc portion 203 preferably contacts the conductive component, so as to have a larger contact area and increase the conductive reliability.
Referring to fig. 13 to 16, in an embodiment, the end of the deformation portion 204 extends outward away from the plane of the substrate 10, and the end of the deformation portion 204 is used to contact and press the conductive component, so that the end of the deformation portion 204 has a larger distance from the substrate 10 in the longitudinal direction, and the deformation portion 204 has a larger compression space in the longitudinal direction, which can provide a larger elastic resisting force, and can also be used to conduct electricity between the conductive component and the external conductive component with a larger distance.
In one embodiment, the width of the end of the connecting portion 201 connected to the base 10 is greater than the width of the end of the connecting portion 201 connected to the supporting portion 202, so that the connecting portion 201 has a wider connecting bottom, a larger connecting area of the connecting portion 201 to the base 10 is ensured, the fatigue resistance of the connecting portion 201 is enhanced, and the service life is prolonged. Of course, the width of the connecting portion 201 may be equal everywhere, and is not limited to the above case.
