Please refer to FIGS. 1 to 4. This embodiment provides a conductive elastic sheet, which includes a base 10 made of a metal material and a first cantilever 20 made of a metal material. The first cantilever 20 includes a connection portion 401 and a support portion 402. The connecting portion 401 is connected to the inside of the base body 10, and the supporting portion 402 extends to the side outside the plane where the base body 10 is located. The number of the first cantilevers 20 may be one or plural, and may be set as required.

In one embodiment, the supporting portion 402 of the first cantilever 20 in the conductive elastic sheet is used to elastically abut against the conductive member, and the side of the conductive elastic sheet where the first cantilever 20 is not provided is used for connection with an external conductive member (may be (Fixed connection or detachable connection). The working principle of the conductive shrapnel at this time can be:

The position of the conductive elastic sheet is fixed so that the first cantilever 20 faces the conductive member that needs to be conductive, and the side of the conductive elastic sheet that is not provided with the first cantilever 20 is connected to the external conductive member.

When the conductive member needs to be connected with the external conductive member, the conductive member contacts the first cantilever 20 and squeezes the first cantilever 20, so that the first cantilever 20 moves toward the plane on which the base body 10 is located, and the support portion 402 deforms during this process. The connecting end of the connecting portion 401 and the supporting portion 402 moves with the movement of the supporting portion 402. At this time, the conductive member elastically abuts against the first cantilever 20, the external conductive member is connected to the base 10, and the first cantilever 20 and the base 10 are connected Therefore, it is ensured that the conductive member is safely and reliably conducted to the external conductive member through the conductive elastic sheet.

When it is no longer necessary to connect the conductive member with an external conductive member, the conductive member is removed, the conductive member no longer squeezes the first cantilever 20, and the support portion 402 is restored in a direction away from the base body 10.

In one embodiment, the conductive elastic sheet can be used in a battery box. At this time, the conductive member can be a battery, such as a new energy battery, and the external conductive member can be a copper plate or a conductive circuit board. When the battery needs to be connected with the external conductive member, the battery contacts the first cantilever 20 and squeezes the first cantilever 20, so that the first cantilever 20 moves toward the plane where the base body 10 is located, wherein the support portion 402 is squeezed toward the base body 10 where it is located The plane moves, so that the battery is electrically connected to the external conductive member through the conductive elastic sheet. When it is no longer necessary to connect the battery with the external conductive member, the battery is removed, the battery no longer squeezes the first cantilever 20, and the support portion 402 is restored in a direction away from the base body 10. It should be understood that the conductive elastic sheet can also be applied to other products, for example, it can be used in electronic products, and its working principle is similar to the above principle, and will not be repeated here.

The beneficial effect of the conductive elastic sheet provided in this embodiment is at least: since the first cantilever 20 capable of elastic compression is provided on one side of the plane where the base body 10 is located, the conductive elastic sheet can elastically abut against the conductive member during use, Effectively ensure that the connection between conductive parts and external conductive parts is tighter, and the conductive connection performance is more stable. In addition, the first cantilever 20 is arranged in two rows opposite to each other. When the conductive part of the conductive member is rectangular or a rectangular-like structure, the cantilever 20 arranged in two rows is more uniformly stressed during contact with the conductive part, and the contact effect is better. , So the conductive effect is also better.

Referring to FIG. 3, in one embodiment, a base body through-hole 100 is formed in the middle of the base body 10. The base body through-hole 100 has a first base wall 101 and a second base wall 102 opposite to each other; The portion 401 is connected to the first side wall 101 and / or the second side wall 102 of the base, and the supporting portion 402 extends to the same side outside the plane where the base 10 is located.

In one embodiment, the connecting portions 401 of the first cantilever 20 are both disposed on the first side wall 101 or the second side wall 102 of the base. At this time, the connecting portions 401 are arranged parallel to each other, and two adjacent connecting portions 401 There are gaps.

Referring to FIG. 3, in one embodiment, a first cantilever 20 is connected to the first side wall 101 and the second side wall 102 of the base. At this time, the first side wall 101 and the second side wall 102 of the base are connected to each other. The number of the first cantilevers 20 may be one or may be multiple, which is not limited herein.

Please refer to FIG. 3. In one embodiment, the number of the first cantilever 20 is multiple. A part of the connecting portion 401 of the first cantilever 20 is connected to the first side wall 101 of the base, and another part of the connecting portion 401 of the first cantilever 20 is connected. A gap L1 is provided between the second side wall 102 of the base body and two adjacent connecting portions 401. For example, the number of the first cantilever 20 is an even number, a part of the connecting portion of the first cantilever 20 is connected to the first side wall 101 of the base, and another part of the connecting portion of the first cantilever 20 is connected to the second side wall 102 of the base; The number of cantilevers on the side wall 101 is the same as the number of cantilevers connected to the second side wall 102 of the base, and the cantilever 20 provided on the first side wall 101 of the base is opposite to the cantilever 20 provided on the second side wall 102 of the base. For example, the number of the first cantilever 20 is six, three connection portions 401 of the first cantilever 20 are connected to the first side wall 101 of the base body, and three connection portions 401 of the first cantilever 20 are connected to the second side wall 102 of the base body. Moreover, the first cantilever 20 provided on the first side wall 101 of the base body is disposed opposite to the first cantilever 20 provided on the second side wall 102 of the base body, which helps to provide a uniform and reliable elastic force. It should be understood that the number of the first cantilever 20 may also be other values, and is not limited to the above-mentioned situation.

Please refer to FIG. 3. In one embodiment, the two ends of the first side wall 101 and the second side wall 102 of the base through-hole 100 are connected by the third side wall 103 and the fourth side wall 104 of the base, respectively. The third side wall 103 and the base fourth side wall 104 may both be arc-shaped, and neither the base third side wall 103 nor the base fourth side wall 104 are connected to the first cantilever 20. It should be understood that, in other embodiments, the shapes of the base third side wall 103 and the base fourth side wall 104 may be other shapes, such as a linear shape or a curved shape, which are not limited herein. The shape of the base body 10 is preferably circular. Of course, the shape of the base body 10 can also be designed according to actual needs. For example, the shape can also be rectangular, which is not limited herein.

Please refer to FIG. 3. In one embodiment, the width of the gap L1 may be less than 5 times the thickness of the base body 10. On the one hand, it is advantageous for processing and molding, and on the other hand, the support portions 402 do not contact each other during use. So that they do not affect each other and the use experience is better. It should be understood that the width of the gap L1 can be set as required, and is not limited herein.

Please refer to FIG. 17 and FIG. 18. In one embodiment, the conductive elastic sheet further includes a second cantilever 30 made of a metal material, wherein the connecting portion 401 of the first cantilever 20 is connected to the first side wall 101 of the base body, and the second cantilever The connecting portion 401 of 30 is connected to the second side wall 102 of the base body; the supporting portion 402 of the first cantilever 20 and the supporting portion 402 of the second cantilever 30 extend to the same side outside the plane of the base body 10; the first cantilever 20 and the second cantilever 30 The projections on the plane on which the base body 10 is located are offset from each other. At this time, the conductive elastic sheet can be regarded as a conductive elastic sheet, and its beneficial effects are at least:

On the one hand, since the first cantilever 20 and the second cantilever 30 which can be elastically compressed are provided on the same side of the plane of the base 10, the conductive elastic sheet can elastically abut the conductive member during use, which can effectively ensure the conductive member and external conductive The components are connected more tightly, and the conductive connection performance is more stable.

On the other hand, the first cantilever 20 and the second cantilever 30 are arranged in two rows, and any adjacent first cantilever 20 and second cantilever 30 are staggered from each other, avoiding the first cantilever 20 and the second cantilever 30 during compression. Cantileveres that are in contact with each other and are staggered in two rows are more uniformly stressed during contact with the conductive part, which has a better contact effect and a better conductive effect. When the conductive part of the conductive member has a rectangular or rectangular-like structure, the first cantilever 20 and the second cantilever 30 that are oppositely arranged in two columns are more uniformly stressed during contact with the conductive part, and the contact effect is better and has a wider range. Usage scenarios.

In one embodiment, the number of the first cantilevers 20 connected to the first side wall 101 of the base body may be one or more; the number of the second cantilever 30 connected to the second side wall 102 of the base body may be one. There can also be multiple, which is not limited here. Any of the first cantilevers 20 and any of the second cantilevers 30 are staggered from each other, thereby ensuring that the projections of the first cantilever 20 and the second cantilever 30 on the plane where the base body 10 is located are staggered from each other.

In one embodiment, the distance between the first side wall 101 and the second side wall 102 of the base is not less than the projection length of the first cantilever 20 or the second cantilever 30 on the plane where the base 10 is located, thereby ensuring that the first cantilever 20 and the The second cantilever 30 does not contact the base body 10 during the compression process. Optionally, the distance between the first side wall 101 and the second side wall 102 of the base is not greater than the sum of the projection lengths of the first cantilever 20 and the second cantilever 30 on the plane where the base 10 is located. This is because the first cantilever The 20 and the second cantilever 30 are staggered to prevent the two from contacting each other during compression. At this time, the size of the base through-hole 100 can have a larger adjustment space (that is, it can be made very large, or it can be made relatively more Small) to meet the needs of different usage scenarios.

Please refer to FIGS. 17 and 18. In one embodiment, the number of the first cantilever 20 is multiple, and the connecting portion 401 of the plurality of first cantilevers 20 is connected to one end of the first side wall 101 of the base; The number is multiple, and a plurality of connecting portions 401 of the second cantilever 30 are connected to one end of the second side wall 102 of the base body; and one end of the first side wall to which the first cantilever 20 is connected and a second side to which the second cantilever 30 is connected. The ends of the walls are staggered from each other. At this time, a plurality of first cantilevers 20 are sequentially adjacent to each other, and a plurality of second cantilevers 30 are sequentially adjacent to each other. The projections of the plane on which 10 is located are arranged in order. For example, the number of the first cantilevers 20 is two, and the two first cantilevers 20 are adjacently arranged; the number of the second cantilever 30 is two, and the two second cantilevers 30 are adjacently arranged. When the above design is adopted, the conductive elastic sheet can be applied to some special scenarios. For example, the conductive part of the conductive member includes two parts staggered from each other. At this time, when the conductive elastic sheet is used, the connection can be ensured to be stable. Of course, the conductive elastic sheet can also be applied to other scenarios, and is not limited to the above-mentioned situations.

Please refer to FIG. 19 and FIG. 20. In one embodiment, the number of the first cantilever 20 and the second cantilever 30 are multiple, and the first cantilever 20 and the second cantilever 30 are alternately arranged. The projections of the second cantilever 30 on the plane where the base body 10 is located are alternately arranged. For example, the number of the first cantilevers 20 is two, and the two first cantilevers 20 are spaced apart; the number of the second cantilever 30 is two, and the two second cantilevers 30 are spaced apart; the first cantilever 20 and the second cantilever 30 are alternately arranged The projection arrangement on the plane where the base body 10 is located is: the first cantilever 20, the second cantilever 30, the first cantilever 20, and the second cantilever 30. Since the first cantilever 20 can be evenly distributed on the first side wall 101 of the base body and the second cantilever 30 can be evenly distributed on the second side wall 102 of the base body at this time, when it comes into contact with the first conductive member and the second conductive member , The force is more balanced.

It should be understood that the first cantilever 20 and the second cantilever 30 can also be distributed on the first side wall 101 and the second side wall 102 of the base in other ways, and it is not limited to the above.

Please refer to FIG. 17 and FIG. 18. In one embodiment, the first side wall 101 and the second side wall 102 of the base body are both flat and relatively parallel. In this case, the third base wall 103 and the fourth base wall 104 may also be a flat surface. The projection shape of the base through-hole 100 is similar to that of a rectangle, and transition walls 105 are provided at the joints of adjacent side walls to make the transition more natural and convenient for stamping.

Referring to FIG. 33 and FIG. 34, in one embodiment, the first side wall 101 and the second side wall 102 of the base body are both curved surfaces, and both are bent toward the outer contour direction of the base body 10. Preferably, the first sidewall 101 and the second sidewall 102 are both arc-shaped surfaces, and the curvature radii of the two are the same. Of course, in other embodiments, only the base first side wall 101 or the base second side wall 102 may be curved, and the base first side wall 101 and the base second side wall 102 may also have other shapes. Make restrictions.

Further, the base body 10, the first cantilever 20, and the second cantilever 30 are integrally formed, and the overall strength is higher; it can be made by using metal conductive materials by stamping, with a simple processing method and high processing efficiency, which can effectively reduce production costs. .

Please refer to FIG. 49 and FIG. 50. In one embodiment, the conductive elastic sheet further includes a fuse 50 and a solder pad 60. The welding pad 60 is made of a metal conductive material. The welding pad 60 is disposed on the other side of the plane where the base body 10 is located. One end of the fuse 50 is connected to the welding pad 60 and the other end of the fuse 50 is connected to the base body 10. The fuse 50 can be quickly blown out when the current exceeds the rated current, so that the electrical connection between the welding pad 60 and the base body 10 is blocked, and the circuit is disconnected, so that it can play the role of overload protection. The beneficial effects of the conductive elastic sheet at this time are:

On the one hand, since the first cantilever 20 is provided on one side of the plane where the base body 10 is located, it is necessary for the conductive conductive member to be pressed against the first cantilever 20 so as to be in close contact with each other; The welding pad 60 is welded to an external electrically conductive component (such as a copper plate), so that the conductive elastic sheet is more firmly connected to the external conductive component, and the problem of unstable conductive connection performance during use is avoided.

On the other hand, a fuse 50 is provided. When the current is too large and exceeds the rated current, the fuse 50 is quickly blown out, so that the electrical connection between the soldering pad 60 and the base body 10 is blocked, and the circuit will be disconnected to provide overload protection. Function, use more secure.

Referring to FIG. 50, in one embodiment, the number of the first cantilevers 20 is multiple, and the plurality of support portions 402 are evenly distributed along the inner side of the base body 10, and the plurality of support portions 402 are connected to the inner side of the base body 10 through the connecting portion 401. . A plurality of first cantilevers 20 are provided, and the plurality of first cantilevers 20 are evenly distributed. When the conductive member squeezes the first cantilever 20, the plurality of first cantilevers 20 can provide a uniform and reliable elastic force, and the overall structure is more stable. A base connecting arm 11 is provided between two adjacent first cantilever arms 20. The base connecting arm 11 is connected to the welding pad 60 through a fuse 50. The width of the base connecting arm 11 is gradually reduced from the side close to the base 10 to the side close to the fuse 50, which is more conducive to the connection between the fuse 50 and the base connecting arm 11.

In one embodiment, the number of the first cantilevers 20 is four, and the number of the base connecting arms 11 is correspondingly four. A base connecting arm 11 is arranged between two adjacent supporting portions 402, that is, four supporting portions 402 and four base connecting arms 11 are evenly staggered. It should be understood that the number of the first cantilever 20 and the base connecting arm 11 can be set as required, and is not limited to the above-mentioned situation.

Please refer to FIG. 50. In one embodiment, the width d of the narrowest part of the fuse 50 is smaller than the average value of the width of the cantilever. On the one hand, it can play the role of overload protection, and on the other hand, it can ensure that it can be within the rated current range. normal work.

Please refer to FIG. 52. In one embodiment, the welding disk 60 is parallel to the base body 10. The distance h between the welding disk 60 and the plane of the base body 10 is less than 10 times the thickness of the base body 10. On the one hand, it is ensured that the welding disk 60 has a certain distance from the base body 10. The height of the soldering pad 60 facilitates welding between the soldering pad 60 and an external circuit.
