DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0057] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0058] The inventor of the present application found that during the battery assembly process, the end face of the battery electrode (positive or negative) is generally in contact with the adapter to achieve electrical connection, but the battery electrode is still easily offset relative to the adapter after contacting the adapter, resulting in poor contact between the electrode and the adapter. The embodiment of the present application provides an electrical component that can better prevent the electrical connector of the electrical component from offsetting relative to the adapter, thereby improving the poor contact between the electrical connector and the adapter.

[0059] Please refer to Figure 1-Figure 3 , Figure 1 An exploded view of an electrical component in an embodiment of the present application; Figure 2 A schematic diagram for showing the cooperation between the adapter 100 and the battery 200; Figure 3It is a schematic diagram used to show the separation of the adapter 100 and the battery 200 in the embodiment of the present application.

[0060] The electrical component is a battery box, a switch component, a remote control, an electric toothbrush, a shaver, a robot, an electric tool, etc. This embodiment is described by taking the electrical component being a battery box as an example. When the electrical component is a battery box, the electrical element is a battery 200, and the electrical connector of the electrical element is an electrode 210.

[0061] The battery box includes an adapter plate 100 , a first shell 300 and a second shell 400 . The first shell 300 and the second shell 400 are connected to form a battery accommodating cavity for accommodating the battery 200 and the adapter plate 100 .

[0062] The battery receiving cavity formed by connecting the first shell 300 and the second shell 400 matches the shape of the battery 200. The adapter plate 100 is arranged in the battery receiving cavity. When the battery 200 is assembled in the battery receiving cavity, the electrode 210 of the battery 200 cooperates with the adapter plate 100 to achieve electrical connection.

[0063] In this embodiment, the battery 200 is a cylindrical battery. Accordingly, the battery accommodating cavity formed by connecting the first shell 300 and the second shell 400 is a cylindrical cavity, which is adapted to the shape of the battery 200; a base plate is provided on the second shell 400, and the adapter plate 100 is provided on the base plate. The connection method between the adapter plate 100 and the base plate includes but is not limited to snap-in, welding, bonding or connection through fasteners such as bolts, and the connection method between the first shell 300 and the second shell 400 includes but is not limited to snap-in, hinged, sliding connection or connection through fasteners such as bolts.

[0064] In other embodiments, the battery 200 is a square battery, and accordingly, the battery receiving cavity formed by connecting the first shell 300 and the second shell 400 is a square cavity. Of course, the battery 200 can also be in other shapes besides cylindrical batteries and square batteries, as long as the battery 200 matches the shape of the battery receiving cavity.

[0065] Please refer to Figure 4 , Figure 5 , Figure 4 This is a schematic structural diagram of the adapter sheet 100 from a first viewing angle in an embodiment of the present application; Figure 5 Schematic diagram of the structure of the adapter 100 from a second viewing angle in the embodiment of the present application.

[0066] The adapter 100 provided in the embodiment of the present application is used to fix the electrode 210 of the battery 200. The adapter 100 includes an adapter body 110, an abutment sheet 120, an inlet stopper 130 and a head stopper 140; the abutment sheet 120 is connected to the adapter body 110 and is used to abut against the end surface of the electrode 210 of the battery 200 to achieve electrical connection; the number of the inlet stopper 130 is at least two, all of the inlet stopper 130 and the head stopper 140 are connected to the adapter body 110, and the two inlet stopper 130 opposite to each other are spaced apart. An opening 150 is formed in between for the electrode 210 to enter laterally, and a head limiting plate 140 and two entrance limiting plates 130 spaced opposite to each other are distributed around the abutment plate 120; wherein, the two entrance limiting plates 130 spaced opposite to each other are used to guide and avoid the electrode 210 in the process of the electrode 210 passing through the opening 150, and to limit and block the tail side of the electrode 210 when the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutment plate 120 and the head side of the electrode 210 abuts against the head limiting plate 140.

[0067] In this embodiment, the battery 200 is described as a cylindrical battery. The electrode 210 of the cylindrical battery is cylindrical and protrudes at one end of the battery 200, so that the electrode 210 has perpendicular end faces and side faces; the head side face of the electrode 210 refers to the side face of the electrode 210 facing the head limiting plate 140, and the tail side face of the electrode 210 refers to the side face of the electrode 210 facing away from the head limiting plate 140.

[0068] It is understandable that, in other embodiments, the battery 200 may also be a square battery, and accordingly, the electrode 210 of the square battery is a rectangular body.

[0069] This embodiment is described with two entrance limit plates 130 as the number. An opening 150 is formed between the two entrance limit plates 130 for the electrode 210 to enter laterally. The two entrance limit plates 130 are symmetrically arranged on both sides of the center line L of the opening 150. The head limit plate 140 and the two entrance limit plates 130 are distributed around the abutment plate 120 to form multi-point limitations on the side of the electrode 210.

[0070] It can be understood that in other embodiments, the number of entrance limit plates 130 can also be an even number such as four or six. For example, when the number of entrance limit plates 130 is four, the four entrance limit plates 130 are symmetrically arranged in pairs on both sides of the center line L of the opening 150, wherein the two entrance limit plates 130 close to the outside of the opening 150 are used to guide the electrode 210, and the two entrance limit plates 130 close to the inside of the opening 150 are used to guide and limit the electrode 210.

[0071] When the electrode 210 passes through the opening 150, the two entrance limit plates 130 guide and avoid the electrode 210. When the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutment plate 120, and the head side of the electrode 210 abuts against the head limit plate 140, the two entrance limit plates 130 limit and block the tail side of the electrode 210. The two entrance limit plates 130 and the head limit plate 140 form multi-point limits on the side of the electrode 210, which can better prevent the electrode 210 from shifting relative to the adapter plate 100, so that the end face of the electrode 210 is always in abutment with the abutment plate 120, thereby improving the poor contact between the electrode 210 and the adapter plate 100.

[0072] Please refer to Figure 6 , Figure 6 Schematic diagram of the structure of the entrance limiting piece 130 in the embodiment of the present application.

[0073] In this embodiment, the entrance limiting plate 130 includes a first connecting portion 131, a first elastic portion 132 and a first limiting portion 133 which are connected in sequence toward the head limiting plate 140. The first connecting portion 131 is connected to the adapter plate body 110, and the first elastic portion 132 and the first limiting portion 133 are both spaced apart and movable from the adapter plate body 110; the first connecting portion 131 is used to guide the electrode 210 entering laterally; the first limiting portion 133 is used to avoid the electrode 210 under the action of the first elastic portion 132 when the electrode 210 passes through the opening 150, and is used to limit and block the tail side of the electrode 210 when the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutment plate 120, and the head side of the electrode 210 abuts against the head limiting plate 140.

[0074] The adapter plate 100 has a symmetrical structure along the center line L of the opening 150. The two first connecting portions 131 are respectively connected to the edges of the adapter plate body 110 located on both sides of the center line of the opening 150. The first elastic portion 132 and the first limiting portion 133 have a gap with the adapter plate body 110, so that the first elastic portion 132 and the first limiting portion 133 can move relative to the adapter plate body 110.

[0075] The extension direction of the first connection portion 131 on the plane parallel to the adapter plate body 110 is inclined relative to the extension direction of the center line L of the opening 150, and the distance between the ends of the two first connection portions 131 away from the head limiting plate 140 is greater than the distance between the ends of the two first connection portions 131 close to the head limiting plate 140, so that the two first connection portions 131 guide the electrode 210 when the electrode 210 moves along the center line L of the opening 150 toward the head limiting plate 140.

[0076] Please refer to Figure 7 , Figure 7 This is a first front view of the adapter 100 in the embodiment of the present application.

[0077] In this embodiment, an angle θ1 between the extending direction of the first connection portion 131 and the center line L of the opening 150 is 14-20°.

[0078] The angle θ1 between the extension direction of any first connection part 131 on the plane parallel to the adapter body 110 and the center line L direction of the opening 150 is 14-20°. Optionally, the angle θ1 is 14°, 17° or 20°, which can be selected within the above range according to actual working conditions; when the angle θ1 is in the range of 14-20°, the two first connection parts 131 can play a good guiding role for the electrode 210. When the first connection part 131 guides the electrode 210, it is not easy to generate a large friction force between the electrode 210 and the electrode 210, thereby reducing the wear between the first connection part 131 and the electrode 210, so that the electrode 210 can pass through the opening 150 more smoothly and abut against the first limiting part 133; if the angle is too small, it will cause a large friction force to be generated between the first connection part 131 and the electrode 210, which is not conducive to the electrode 210 passing through the opening 150; if the angle is too large, it cannot play a good guiding role for the electrode 210.

[0079] After the two first connecting parts 131 guide the electrode 210, the side of the head of the electrode 210 abuts against the part of the first limiting part 133 close to the first elastic part 132, pushing the two first limiting parts 133 to move outside the adapter body 110. At this time, the first elastic part 132 is deformed, and the first limiting part 133 avoids the electrode 210 when the first elastic part 132 is deformed; and the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutting sheet 120 and the side of the head of the electrode 210 When abutting against the head limiting plate 140, the first limiting portion 133 moves toward the inside of the adapter plate body 110 under the resetting action of the first elastic portion 132 until the part of the first limiting portion 133 away from the first elastic portion 132 abuts against the tail side of the electrode 210. At this time, since the elastic force of the first elastic portion 132 always exists, the elastic force generated by the two first elastic portions 132 acts on the tail side of the electrode 210 through the two first limiting portions 133, making it difficult for the electrode 210 to fall out from one side of the opening 150.

[0080] In this embodiment, the first limiting portion 133 and the first elastic portion 132 are both arc-shaped. The first limiting portion 133 is convex toward the opening 150 , and the first elastic portion 132 is concave toward the opening 150 .

[0081] It should be noted that the surface of the first limiting portion 133 facing the opening 150 is a convex surface, and the surface of the first elastic portion 132 facing the opening 150 is a concave surface.

[0082] In other embodiments, the first limiting portion 133 and the first elastic portion 132 are both in a straight line shape, or one of the first limiting portion 133 and the first elastic portion 132 is in a straight line shape, and the other is in an arc shape.

[0083] Please refer to Figure 8 , Figure 8 Schematic diagram of the partial structure of the head limiting piece 140 in the embodiment of the present application.

[0084] In this embodiment, the head limiting plate 140 includes a second connecting portion 141, a second elastic portion 142 and a second limiting portion 143 which are connected in sequence, the second connecting portion 141 is connected to the adapter plate body 110, and the second elastic portion 142 and the second limiting portion 143 are movable at intervals from the adapter plate body 110; the second limiting portion 143 is used to move back to the abutting plate 120 under the elastic action of the second elastic portion 142 after being abutted by the head side of the electrode 210, and under the resetting action of the second elastic portion 142, it abuts against the head side and the tail side of the electrode 210 respectively with the first limiting portion 133, thereby clamping the electrode 210 together; wherein, when the adapter plate 100 is in the reset state, the first limiting portion 133 and the second limiting portion 143 define an inscribed circle representing the clamped electrode 210.

[0085] The adapter body 110 has a relative head and tail, the second connecting portion 141 is connected to the head of the adapter body 110, and the opening 150 is located at the tail of the adapter body 110; the second elastic portion 142 and the second limiting portion 143 both have a gap with the adapter body 110, so that the second elastic portion 142 and the second limiting portion 143 can move relative to the adapter body 110.

[0086] The side surface of the head of the electrode 210 can abut against the second limiting portion 143 and push the second limiting portion 143 to move toward the outside of the adapter body 110. At this time, the second elastic portion 142 is deformed, which has a certain buffering effect on the insertion of the electrode 210. In addition, under the reset action of the second elastic portion 142, the second limiting portion 143 is always abutted against the side surface of the head of the electrode 210, and the first limiting portion 133 is always abutted against the side surface of the tail of the electrode 210. The second limiting portion 143 and the first limiting portion 133 cooperate to clamp the side surface of the electrode 210.

[0087] When the adapter plate 100 is in the reset state, the first limiting portion 133 and the second limiting portion 143 are both in the initial position, and the first elastic portion 132 and the second elastic portion 142 are not deformed. At this time, the first limiting portion 133 and the second limiting portion 143 jointly define an inscribed circle representing the clamping electrode 210.

[0088] In this embodiment, the second elastic portion 142 and the second limiting portion 143 are symmetrically distributed on both sides of the second connecting portion 141 .

[0089] The second connection portion 141 extends in a plane parallel to the adapter body 110 along the direction of the center line L of the opening 150, and both ends of the second connection portion 141 are connected to the second elastic portion 142 and the second limiting portion 143 in sequence. The second elastic portion 142 and the second limiting portion 143 at both ends of the second connection portion 141 are symmetrically arranged along the center line L of the opening 150.

[0090] When the side of the head of the electrode 210 abuts against the head limiting plate 140, the two second limiting portions 143 abut against the side of the head of the electrode 210 under the resetting action of the second elastic portions 142 connected to each other, and the two second limiting portions 143 cooperate with the two first limiting portions 133 to form a four-point limit on the side of the electrode 210, preventing the electrode 210 from deviating along the center line L of the opening 150, thereby improving the stability of the electrode 210.

[0091] In other embodiments, the second connecting portion 141 is only provided with the second elastic portion 142 and the second limiting portion 143 on one side. For example, the second connecting portion 141 is provided on one side of the center line of the opening 150, and the second connecting portion 141, the second elastic portion 142 and the second limiting portion 143 are connected in sequence. The portion where the second limiting portion 143 abuts against the side surface of the head of the electrode 210 is located on the center line L of the opening 150. At this time, the second limiting portion 143 cooperates with the two first limiting portions 133 to form a three-point limit on the side surface of the electrode 210, which can also prevent the electrode 210 from deviating along the center line L direction of the opening 150, thereby improving the stability of the electrode 210.

[0092] In this embodiment, the second elastic portion 142 and the second limiting portion 143 are both arc-shaped. The second limiting portion 143 is convex toward the inner side of the adapter body 110 , and the second elastic portion 142 is concave toward the inner side of the adapter body 110 .

[0093] It should be noted that the surface of the second limiting portion 143 facing the inner side of the adapter body 110 is a convex surface, and the surface of the second elastic portion 142 facing the inner side of the adapter body 110 is a concave surface.

[0094] In other embodiments, the second limiting portion 143 and the second elastic portion 142 are both in a straight line shape, or one of the second limiting portion 143 and the second elastic portion 142 is in a straight line shape, and the other is in an arc shape.

[0095] Please refer to Fig. 9 , Fig. 9 This is a second front view of the adapter sheet 100 in the embodiment of the present application.

[0096] In this embodiment, the ratio of the radius R0 of the inscribed circle to the radius R1 of the first limiting portion 133 is (3-3.2):1, and the ratio of the radius R0 of the inscribed circle to the radius R2 of the first elastic portion 132 is (2.9-3.1):1.

[0097] Under the above-mentioned radius ratio, the radius R2 of the first elastic part 132 is greater than the radius R1 of the first limiting part 133, so that the first elastic part 132 is easy to deform when the electrode 210 pushes the first limiting part 133 to move toward the outside of the adapter plate body 110. When the two first limiting parts 133 cooperate with the two second limiting parts 143 to jointly support the side of the electrode 210, the resetting action of the two first elastic parts 132 jointly gives the electrode 210 a force to move toward the head limiting plate 140, thereby making it difficult for the electrode 210 to detach from the opening 150.

[0098] Exemplarily, the ratio of the radius R0 of the inscribed circle to the radius R1 of the first limiting portion 133 is 3:1, 3.1:1 or 3.2:1, and the ratio of the radius R0 of the inscribed circle to the radius R2 of the first elastic portion 132 is 2.9:1, 3:1 or 3.1:1. It can be understood that the ratio of the radius R0 of the inscribed circle to the radius R1 of the first limiting portion 133 and the ratio of the radius R0 of the inscribed circle to the radius R2 of the first elastic portion 132 can be selected within the above range according to actual working conditions.

[0099] In this embodiment, the ratio of the radius R0 of the inscribed circle to the radius R3 of the second limiting portion 143 is (3-3.2):1, and the ratio of the radius R0 of the inscribed circle to the radius R4 of the second elastic portion 142 is (2.9-3.1):1.

[0100] Under the above-mentioned radius ratio, the radius R4 of the second elastic part 142 is greater than the radius R3 of the second limiting part 143, so that the second elastic part 142 is easy to deform when the electrode 210 pushes the second limiting part 143 toward the outside of the adapter plate body 110, which plays a better buffering role, and the second limiting part 143 and the electrode 210 are not prone to wear; and when the two first limiting parts 133 cooperate with the two second limiting parts 143 to jointly support the side of the electrode 210, the resetting effect of the two second elastic parts 142 jointly gives the electrode 210 a force to move away from the head limiting plate 140, which balances the force given to the electrode 210 by the two first elastic parts 132, so that the electrode 210 can be stably clamped between the first limiting part 133 and the second limiting part 143.

[0101] Exemplarily, the ratio of the radius R0 of the inscribed circle to the radius R3 of the second limiting portion 143 is 3:1, 3.1:1 or 3.2:1, and the ratio of the radius R0 of the inscribed circle to the radius R4 of the second elastic portion 142 is 2.9:1, 3:1 or 3.1:1. It can be understood that the ratio of the radius R0 of the inscribed circle to the radius R3 of the second limiting portion 143 and the ratio of the radius R0 of the inscribed circle to the radius R4 of the second elastic portion 142 can be selected within the above range according to actual working conditions.

[0102] Please refer to Fig.10 , Fig.10 This is a third front view of the adapter 100 in the embodiment of the present application.

[0103] The angle between the line between the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line between the center of the second limiting portion 143 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13-15°; the angle between the line between the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line between the center of the first limiting portion 133 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13-15°.

[0104] In this embodiment, the angle θ2 between the line connecting the center of the first limiting portion 133 above the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the second limiting portion 143 below the center line L of the opening 150 and the center of the inscribed circle is 13-15°, and the angle θ3 between the line connecting the center of the second limiting portion 143 above the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the first limiting portion 133 below the center line L of the opening 150 and the center of the inscribed circle is 13-15°.

[0105] By limiting the angle range between the line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the second limiting portion 143 on the other side of the center line L of the opening 150 and the center of the inscribed circle, and the angle range between the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle and the line connecting the center of the first limiting portion 133 on the other side of the center line L of the opening 150 and the center of the inscribed circle, the two angle ranges are consistent, so that the forces exerted on the electrode 210 by the two first limiting portions 133 and the forces exerted on the electrode 210 by the two second limiting portions 143 are balanced, so that the electrode 210 is clamped more stably between the first limiting portion 133 and the second limiting portion 143.

[0106] Exemplarily, the angle between the line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle and the angle between the line connecting the center of the second limiting portion 143 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13°, 14° or 15°, and the angle between the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle and the angle between the line connecting the center of the first limiting portion 133 on the other side of the center line L of the opening 150 and the center of the inscribed circle is 13°, 14° or 15°; it can be understood that the sizes of the two angles can be selected within the above-mentioned angle range according to the actual working conditions, as long as the sizes of the two angles are equal.

[0107] The line connecting the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle is tangent to the second limiting portion 143 on the other side of the center line L of the opening 150; the line connecting the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle is tangent to the first limiting portion 133 on the other side of the center line L of the opening 150.

[0108] By limiting the connection line between the center of the first limiting portion 133 on one side of the center line L of the opening 150 and the center of the inscribed circle to be tangent to the second limiting portion 143 on the other side of the center line L of the opening 150, and the connection line between the center of the second limiting portion 143 on one side of the center line L of the opening 150 and the center of the inscribed circle to be tangent to the first limiting portion 133 on the other side of the center line L of the opening 150, when the two first limiting portions 133 and the two second limiting portions 143 jointly limit the electrode 210, any one of the two first limiting portions 133 and the two second limiting portions 143 is in line contact with the side surface of the electrode 210. At this time, it can not only play the role of multi-point limiting for the electrode 210, but also is not easy to cause wear to the side surface of the electrode 210, thereby ensuring the service life of the electrode 210.

[0109] In this embodiment, the diameter of the inscribed circle is smaller than the diameter of the electrode 210 .

[0110] When the diameter of the inscribed circle is smaller than the diameter of the electrode 210 , the two first limiting portions 133 are simultaneously interference fit with the tail side of the electrode 210 , and the two second limiting portions 143 are simultaneously interference fit with the head side of the electrode 210 , which provides a better clamping effect on the electrode 210 .

[0111] Exemplarily, the diameter of the inscribed circle is 3.6-4.0 mm, and correspondingly, the diameter of the electrode 210 is 4.1-4.5 mm. The diameter of the inscribed circle is smaller than the diameter of the electrode 210, so that the two first limiting portions 133 and the two second limiting portions 143 are simultaneously interference fit with the side of the electrode 210, giving a suitable clamping force to the side of the electrode 210, which is not easy to damage the electrode 210 and can also provide a good clamping effect on the electrode 210.

[0112] It is understandable that the diameter of the inscribed circle is only an exemplary description. In actual applications, the diameter of the inscribed circle can be adaptively adjusted according to the diameter of the electrode 210 as long as the diameter of the inscribed circle is smaller than the diameter of the electrode 210 .

[0113] There are multiple first elastic parts 132, which are connected in sequence, and two of the multiple first elastic parts 132 located at both ends are respectively connected to the first limiting part 133 and the first connecting part 131; and / or there are multiple second elastic parts 142, which are connected in sequence, and two of the multiple second elastic parts 142 located at both ends are respectively connected to the second limiting part 143 and the second connecting part 141.

[0114] In this embodiment, the number of the first elastic portion 132 is one, and the two ends of the first elastic portion 132 are respectively connected to the first limiting portion 133 and the first connecting portion 131; the number of the second elastic portions 142 is two, and the two second elastic portions 142 are connected in sequence, one of the second elastic portions 142 is connected to the second limiting portion 143, and the other second elastic portion 142 is connected to the second connecting portion 141.

[0115] In other embodiments, there are multiple first elastic portions 132, and two first elastic portions 132 located at both ends of the multiple first elastic portions 132 are respectively connected to the first limiting portion 133 and the first connecting portion 131, and there is one second elastic portion 142, and both ends of the second elastic portion 142 are respectively connected to the second limiting portion 143 and the second connecting portion 141; or, there are multiple first elastic portions 132, and two first elastic portions 132 located at both ends of the multiple first elastic portions 132 are respectively connected to the first limiting portion 133 and the first connecting portion 131, and there are multiple second elastic portions 142, and two second elastic portions 142 located at both ends of the multiple second elastic portions 142 are respectively connected to the second limiting portion 143 and the second connecting portion 141.

[0116] In practical applications, the number of the first elastic portion 132 and the second elastic portion 142 can be determined according to actual working conditions, as long as the first limiting portion 133 under the resetting action of the first elastic portion 132 and the second limiting portion 143 under the resetting action of the second elastic portion 142 provide appropriate clamping force to the side of the electrode 210.

[0117] In this embodiment, the first connection portion 131 and the second connection portion 141 are both vertically connected to the adapter body 110 .

[0118] The first connecting portion 131 and the second connecting portion 141 are both vertically connected to the adapter body 110, so that the first elastic portion 132, the first limiting portion 133, the second elastic portion 142 and the second limiting portion 143 are all vertically connected to the adapter body 110. When the electrode 210 passes through the opening 150, the first limiting portion 133 and the second limiting portion 143 simultaneously abut against the side surface of the electrode 210, and the abutting sheet 120 abuts against the end surface of the electrode 210.

[0119] In this embodiment, the adapter body 110 , the abutting piece 120 , the entrance limiting piece 130 and the head limiting piece 140 are integrally formed, and the first connecting portion 131 and the second connecting portion 141 are both bent relative to the adapter body 110 .

[0120] The first connection portion 131 and the second connection portion 141 are both bent at 110° relative to the adapter body. The entrance limiting plate 130 is integrally formed with the adapter body 110 through the first connection portion 131, and the head limiting plate 140 is integrally formed with the adapter body 110 through the second connection portion 141, so that the overall stability of the adapter 100 is better.

[0121] In other embodiments, the first connection portion 131 and the second connection portion 141 are simultaneously plugged into the adapter body 110 , or the first connection portion 131 and the second connection portion 141 are simultaneously connected to the adapter body 110 via fasteners such as screws.

[0122] In this embodiment, the abutment sheet 120 is an elastic abutment sheet, and the abutment sheet 120 has a relatively fixed end 121 and a free end 122. The fixed end 121 is connected to the adapter sheet body 110. The fixed end 121 is closer to the opening 150 than the free end 122. The free end 122 is spaced apart from the adapter sheet body 110, and the free end 122 is used to abut against the end face of the electrode 210 to achieve electrical connection.

[0123] The extension direction of the abutment sheet 120 is inclined relative to the adapter sheet body 110. In the process of the electrode 210 passing through the opening 150 until the side of the head of the electrode 210 abuts against the second limiting portion 143, the end face of the electrode 210 presses down the free end 122 of the abutment sheet 120, so that the free end 122 of the abutment sheet 120 gradually approaches the adapter sheet body 110. The angle between the abutment sheet 120 and the adapter sheet body 110 becomes smaller, causing the abutment sheet 120 to deform. The resetting effect of the abutment sheet 120 ensures that the free end 122 of the abutment sheet 120 always abuts against the end face of the electrode 210, thereby ensuring the stability of the electrical connection.

[0124] Optionally, there are multiple abutment sheets 120, and multiple free ends 122 are simultaneously used to abut against the end surface of the electrode 210 to achieve electrical connection.

[0125] In this embodiment, there are two abutment sheets 120, and the extension directions of the two abutment sheets 120 are consistent. In the process that the electrode 210 passes through the opening 150 until the side surface of the head of the electrode 210 abuts against the second limiting portion 143, the free ends 122 of the two abutment sheets 120 abut against the end surface of the electrode 210 at the same time, and two-point contact is always maintained between the end surface of the electrode 210, thereby further improving the stability of the electrical connection and reducing the probability of electrical connection failure.

[0126] It is understandable that the number of abutment sheets 120 can be more than three, and the extension directions of the multiple abutment sheets 120 can be different, as long as the free ends 122 of the multiple abutment sheets 120 can abut the end surface of the electrode 210 at the same time and always maintain multi-point contact with the end surface of the electrode 210.

[0127] In this embodiment, a through hole 111 is defined in the adapter body 110 , the fixed end 121 is connected to the inner wall of the through hole 111 , and the free end 122 extends in a direction away from the adapter body 110 .

[0128] The through hole 111 is rectangular in shape, and the fixed ends 121 of the two abutment pieces 120 are connected to the inner wall of the through hole 111 close to the opening 150. The free ends 122 of the two abutment pieces 120 extend toward the head limiting piece 140 and away from the adapter piece body 110. By arranging the abutment piece 120 in the through hole 111, on the one hand, the abutment piece 120 can be easily deformed and not easily hinder the electrode 210 from passing through the opening 150. On the other hand, the resetting effect of the abutment piece 120 after deformation ensures that the free end 122 of the abutment piece 120 is always in abutment with the end face of the electrode 210.

[0129] In other embodiments, the shape of the through hole 111 may also be circular, trapezoidal or other polygonal shapes.

[0130] An embodiment of the present application further provides an electric meter, comprising an electric meter body and the above-mentioned electrical component, wherein the electrical component is disposed in the electric meter body, and the electrical element is used to supply power to the electric meter body.

[0131] The electric meter includes the above-mentioned adapter 100. The technical effect of the electric meter is substantially the same as the technical effect of the adapter 100 and the electrical component, and will not be described in detail here.

[0132] In summary, the embodiment of the present application provides an adapter plate 100, an electrical component and an electric meter. In the process of the electrode 210 passing through the opening 150, the entrance limit plate 130 guides and avoids the electrode 210, and when the electrode 210 passes through the opening 150, the end face of the electrode 210 abuts against the abutment plate 120 and the head side of the electrode 210 abuts against the head limit plate 140, the entrance limit plate 130 limits and blocks the tail side of the electrode 210. The entrance limit plate 130 and the head limit plate 140 form multi-point limits on the side of the electrode 210, which can better prevent the electrode 210 from shifting relative to the adapter plate 100, so that the end face of the electrode 210 is always abutted against the abutment plate 120, thereby improving the poor contact between the electrode 210 and the adapter plate 100.

[0133] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
