[0007] To achieve the purpose of the present invention, the following technical solutions are adopted:

[0008] The invention of the first technical solution is an electrical connection crown spring, which includes a flat body and a plurality of spring strips arranged on the body, the body is bent into a cylindrical structure, a portion of the spring strips is bent from the inside of the cylindrical structure to the outside of the cylindrical structure, and a portion of the spring strips is bent from the outside of the cylindrical structure to the inside of the cylindrical structure.

[0009] In addition, the electrical connection crown spring of the second technical solution is based on the electrical connection crown spring of the first technical solution, and two adjacent spring strips are grouped together, and in the two adjacent groups of spring strips:

[0010] One group of the spring bars is bent from the inside of the tubular structure to the outside of the tubular structure, and the other group of the spring bars is bent from the outside of the tubular structure to the inside of the tubular structure.

[0011] In addition, the electrical connection crown spring of the third technical solution is based on the electrical connection crown spring of the second technical solution, and the two ends of each group of the spring strips are respectively connected to the body through respective connecting pieces.

[0012] In addition, the electrical connection crown spring of the fourth technical solution is based on the electrical connection crown spring of any one of the first to third technical solutions, and the body is provided with snap-fit ​​grooves at the two ends of the spring bar, respectively, and the snap-fit ​​grooves are arranged at intervals in pairs, so that a snap-fit ​​protrusion is formed between each two adjacent snap-fit ​​grooves.

[0013] In addition, the electrical connection crown spring of the fifth technical solution is based on the electrical connection crown spring of the fourth technical solution, and each of the clamping protrusions is bent from the inside of the tubular structure to the outside of the tubular structure.

[0014] In addition, the electrical connection crown spring of the sixth technical solution is based on the electrical connection crown spring of the fifth technical solution, and the angles formed between each of the clamping protrusions and the central axis of the tubular structure are equal.

[0015] In addition, the electrical connection crown spring of the seventh technical solution is based on the electrical connection crown spring of any one of the first to third technical solutions, wherein each of the spring strips is formed in a wave shape.

[0016] In addition, the electrical connection crown spring of the eighth technical solution is based on the electrical connection crown spring of any one of the first to third technical solutions, and an opening extending along the length direction of the body is provided on the body.

[0017] In addition, the electrical connection crown spring of the ninth technical solution is based on the electrical connection crown spring of any one of the first to third technical solutions, and each of the spring strips is a continuous structure.

[0018] In addition, the electrical connection crown spring of the tenth technical solution is based on the electrical connection crown spring of any one of the first to third technical solutions, and an anti-oxidation coating is applied on the outer surfaces of the body and the spring strip respectively.

[0019] Combined with the above technical solutions, the beneficial effects brought by the present invention are analyzed as follows:

[0020] In the prior art, the mutual connection between the male terminal and the female terminal of the electrical connector is unstable, which can easily cause current interruption during the connector connection process, or current instability such as intermittent current, thereby greatly affecting the stable current transmission and high-power current transmission.

[0021] In contrast, according to the invention of technical solution 1, an electrical connection crown spring is provided, which includes a flat body and a plurality of spring strips arranged on the body, the body is bent into a cylindrical structure, a portion of the spring strips is bent from the inside of the cylindrical structure to the outside of the cylindrical structure, and a portion of the spring strips is bent from the outside of the cylindrical structure to the inside of the cylindrical structure.

[0022] When in use, it is placed in the female terminal in a manner of surrounding the end of the male terminal to achieve a stable connection between the male terminal and the female terminal.

[0023] The present invention can increase the contact area between connectors, ensure the stability of connector connection, and enable the connector to have a larger current flow rate.

[0024] More specifically, since a portion of the spring strip in the present invention bends from the inside of the tubular structure to the outside of the tubular structure, and a portion of the spring strip bends from the outside of the tubular structure to the inside of the tubular structure, the spring strip is partially bulged toward the outside of the tubular structure and partially sunken toward the inside of the tubular structure. Compared with extending the entire spring strip in a direction parallel to the axis of the tubular structure, the outwardly bulging portion of the spring strip is in full contact with the inner surface of the female terminal, and the inwardly sunken portion of the spring strip is in full contact with the outer surface of the male terminal. Thus, a significantly better current conduction effect is achieved that cannot be achieved by a structure in which the entire spring strip is extended in a direction parallel to the axis of the tubular structure, a stable connection between the male terminal and the female terminal can be achieved, and reliability is provided for high-power power supply.

[0025] According to the invention of the second technical solution, based on the invention of the first technical solution, two adjacent spring bars are grouped together, and in the two adjacent groups of spring bars: one group of spring bars is bent from the inside of the tubular structure to the outside of the tubular structure, and the other group of spring bars is bent from the outside of the tubular structure to the inside of the tubular structure.

[0026] Thus, the spring strips form an orderly structure inside and outside, which is conducive to the uniform distribution of current between the spring strips when the current flows along the axial direction of the spring strips, further ensuring the stability of the current flow and the safety of the current flow.

[0027] According to the invention of the third technical solution, based on the invention of the second technical solution, both ends of each group of spring bars are connected to the body through respective connecting pieces.

[0028] Therefore, the connection between the spring strip and the body can be fixed by the connecting piece, so as to prevent the spring strip from breaking at the connection with the body, thereby ensuring that the electrical connection crown spring has a longer service life.

[0029] According to the invention of the fourth technical solution, on the basis of the invention of any one of the first to third technical solutions, the body is provided with snap-fit ​​grooves at the two ends of the spring bar, and the snap-fit ​​grooves are arranged in pairs, so that a snap-fit ​​protrusion is formed between each two adjacent snap-fit ​​grooves.

[0030] Through the above structure, a matching structure can be set on the outer surface of the male terminal or the inner surface of the female terminal accordingly, so that the electrical connection crown spring can be fixed by the above-mentioned clamping protrusion to prevent it from circumferential rotation or axial movement between the male terminal and the female terminal, thereby further ensuring the current stability.

[0031] According to the invention of the fifth technical solution, based on the invention of the fourth technical solution, each engaging protrusion is bent from the inside of the cylindrical structure to the outside of the cylindrical structure.

[0032] Thus, an angle can be formed between each clamping protrusion and the central axis of the tubular structure, so that the clamping protrusion is more in line with the plug-in angle, thereby facilitating plug-in.

[0033] According to the invention of the sixth technical solution, based on the invention of the fifth technical solution, the angles formed between each clamping protrusion and the central axis of the cylindrical structure are equal.

[0034] Therefore, when setting the matching structure on the outer surface of the male terminal or the inner surface of the female terminal, it can be set according to the unified angle standard, and its manufacturing is simpler and more standardized, which is conducive to reducing the working time of processing and manufacturing and improving work efficiency.

[0035] The invention according to claim 7 is based on the invention according to any one of claims 1 to 3, wherein each of the strip springs is formed in a wave shape.

[0036] Therefore, compared with arranging each spring strip to be formed into a long strip shape, the wavy shape can increase the contact area between the spring strip and the terminal surface, thereby further ensuring that the current has a larger stable flow rate.

[0037] According to the invention of claim 8, based on the invention of any one of the first to third claims, an opening extending in the length direction of the body is provided on the body.

[0038] Therefore, the diameter of the cylindrical structure can be adjusted through the opening, so that the electrical connection crown spring can adapt to electrical connection plug-ins of various models and sizes.

[0039] According to the invention of the ninth technical solution, based on the invention of any one of the first to third technical solutions, each spring strip is a continuous structure.

[0040] Therefore, deformation of the spring strip can be avoided, which is beneficial to maintaining the stability of the spring strip's conductivity and extending the overall service life of the electrical connection crown spring.

[0041] According to the invention of the tenth technical solution, based on the invention of any one of the first to third technical solutions, an anti-oxidation coating is applied on the outer surfaces of the body and the spring bar, respectively.

[0042] Therefore, the outer surface of the electrical connection crown spring can be protected by the anti-oxidation coating to prevent it from being oxidized by the external environment.

[0043] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

Figure 2 A front view showing a specific embodiment of the electrical connection crown spring provided by the present invention. Figure 3 A top view showing a specific embodiment of the electrical connection crown spring provided by the present invention.

[0054] like Figures 1 to 3 As shown, this embodiment provides an electrical connection crown spring, which includes a flat body 1 and a plurality of spring strips 2 arranged on the body 1. The body 1 is bent into a cylindrical structure, a portion of the spring strips 2 is bent from the inside of the cylindrical structure to the outside of the cylindrical structure, and a portion of the spring strips 2 is bent from the outside of the cylindrical structure to the inside of the cylindrical structure.

[0055] Furthermore, two adjacent spring bars 2 form a group. In the two adjacent groups of spring bars 2, one group of spring bars 2 bends from the inside of the tubular structure to the outside of the tubular structure, and the other group of spring bars 2 bends from the outside of the tubular structure to the inside of the tubular structure.

[0056] Furthermore, two ends of each group of spring bars 2 are connected to the body 1 through respective connecting pieces 3 .

[0057] In addition, the body 1 is provided with engaging grooves 4 at both ends of the spring strip 2 , and the engaging grooves 4 are arranged in pairs, so that a engaging protrusion 5 is formed between every two adjacent engaging grooves 4 .

[0058] Furthermore, each clamping protrusion 5 is bent from the inside of the cylindrical structure to the outside of the cylindrical structure.

[0059] Furthermore, the angles formed between each clamping protrusion 5 and the central axis of the cylindrical structure are equal.

[0060] In addition, each of the spring strips 2 is formed in a wave shape.

[0061] In addition, the main body 1 is provided with an opening 6 extending along the length direction of the main body 1 .

[0062] In addition, each spring strip 2 is a continuous structure.

[0063] In addition, an anti-oxidation coating is applied on the outer surfaces of the body 1 and the spring strip 2 respectively.

[0064] The specific structure of the present invention is described above, and its usage is described below.

[0065] When in use, the electrical connection crown spring is placed in the female terminal in a manner of surrounding the end of the male terminal, so as to achieve a stable connection between the male terminal and the female terminal.

[0066] The present invention can increase the contact area between connectors, ensure the stability of connector connection, and enable the connector to have a larger current flow rate.

[0067] More specifically, since a portion of the spring strip in the present invention bends from the inside of the tubular structure to the outside of the tubular structure, and a portion of the spring strip bends from the outside of the tubular structure to the inside of the tubular structure, the spring strip is partially bulged toward the outside of the tubular structure and partially sunken toward the inside of the tubular structure. Compared with extending the entire spring strip in a direction parallel to the axis of the tubular structure, the outwardly bulging portion of the spring strip is in full contact with the inner surface of the female terminal, and the inwardly sunken portion of the spring strip is in full contact with the outer surface of the male terminal. Thus, a significantly better current conduction effect is achieved that cannot be achieved by a structure in which the entire spring strip is extended in a direction parallel to the axis of the tubular structure, a stable connection between the male terminal and the female terminal can be achieved, and reliability is provided for high-power power supply.

[0068] In addition, in the above specific embodiment, two adjacent spring bars are grouped together. In the two adjacent groups of spring bars, one group of spring bars bends from the inside of the tubular structure to the outside of the tubular structure, and the other group of spring bars bends from the outside of the tubular structure to the inside of the tubular structure.

[0069] Thus, the spring strips form an orderly structure inside and outside, which is conducive to the uniform distribution of current between the spring strips when the current flows along the axial direction of the spring strips, further ensuring the stability of the current flow and the safety of the current flow.

[0070] In addition, in the above specific implementation, both ends of each group of spring strips are connected to the body through respective connecting pieces.

[0071] Therefore, the connection between the spring strip and the body can be fixed by the connecting piece, so as to prevent the spring strip from breaking at the connection with the body, thereby ensuring that the electrical connection crown spring has a longer service life.

[0072] In addition, in the above-mentioned specific embodiment, the body is provided with engaging grooves at the two ends of the spring strip, and the engaging grooves are arranged in pairs, so that a engaging protrusion is formed between every two adjacent engaging grooves.

[0073] Through the above structure, a matching structure can be set on the outer surface of the male terminal or the inner surface of the female terminal accordingly, so that the electrical connection crown spring can be fixed by the above-mentioned clamping protrusion to prevent it from circumferential rotation or axial movement between the male terminal and the female terminal, thereby further ensuring the current stability.

[0074] In addition, in the above-mentioned specific embodiment, each engaging protrusion is bent from the inside of the cylindrical structure to the outside of the cylindrical structure.

[0075] Thus, an angle can be formed between each clamping protrusion and the central axis of the tubular structure, so that the clamping protrusion is more in line with the plug-in angle, thereby facilitating plug-in.

[0076] In addition, in the above-mentioned specific implementation, the angles formed between each clamping protrusion and the central axis of the cylindrical structure are equal.

[0077] Therefore, when setting the matching structure on the outer surface of the male terminal or the inner surface of the female terminal, it can be set according to the unified angle standard, and its manufacturing is simpler and more standardized, which is conducive to reducing the working time of processing and manufacturing and improving work efficiency.

[0078] In addition, in the above-mentioned specific embodiments, each of the strip springs is formed in a wave shape.

[0079] Therefore, compared with arranging each spring strip to be formed into a long strip shape, the wavy shape can increase the contact area between the spring strip and the terminal surface, thereby further ensuring that the current has a larger stable flow rate.

[0080] In addition, in the above-mentioned specific embodiment, an opening extending along the length direction of the body is provided on the body.

[0081] Therefore, the diameter of the cylindrical structure can be adjusted through the opening, so that the electrical connection crown spring can adapt to electrical connection plug-ins of various models and sizes.

[0082] In addition, in the above specific implementations, each strip spring is a continuous structure.

[0083] Therefore, deformation of the spring strip can be avoided, which is beneficial to maintaining the stability of the spring strip's conductivity and extending the overall service life of the electrical connection crown spring.

[0084] In addition, in the above-mentioned specific implementation, an anti-oxidation coating is applied on the outer surfaces of the body and the spring strip, respectively.

[0085] Therefore, the outer surface of the electrical connection crown spring can be protected by the anti-oxidation coating to prevent it from being oxidized by the external environment.

[0086] In addition, in the specific structure of the above-mentioned specific embodiment, a plurality of protrusions extending along the extension direction of the spring strips can be further provided on each spring strip to increase the contact area between the spring strips and the contacting electrical connector, thereby ensuring sufficient contact between the spring strips and the electrical connector, and further ensuring a larger current flow rate.

[0087] The structures of the specific embodiments of the present invention are described above, but are not limited thereto.

[0088] For example, in the above specific embodiment, two adjacent spring bars are grouped together. In the two adjacent groups of spring bars, one group of spring bars bends from the inside of the tubular structure to the outside of the tubular structure, and the other group of spring bars bends from the outside of the tubular structure to the inside of the tubular structure.

[0089] However, it is not limited to this. In the above structure, four adjacent spring bars can be formed into a group. In the adjacent four groups of spring bars, one group of spring bars at the edge is bent from the inside of the tubular structure to the outside of the tubular structure, the middle group of spring bars is parallel to the central axis of the tubular structure, and the other group of spring bars at the edge is bent from the outside of the tubular structure to the inside of the tubular structure; or, all spring bars are arranged in a manner of two adjacent spring bars, one of which is bent from the inside of the tubular structure to the outside of the tubular structure, and the other is bent from the outside of the tubular structure to the inside of the tubular structure. All of these can achieve the above-mentioned structure of the spring bars with an orderly structure inside and outside, which is conducive to the uniform distribution of current between the spring bars when the current flows along the axis direction of the spring bars, further ensuring the stability of the current passing, and at the same time ensuring the safety of the current passing.

[0090] However, according to the structure in the specific implementation mode, it can ensure a large flow rate while ensuring good supporting performance and avoiding deformation of the spring strip.

[0091] In addition, in the above specific implementation, both ends of each group of spring strips are connected to the body through respective connecting pieces.

[0092] However, the present invention is not limited thereto, and the connecting piece mentioned above may not be provided, and the function of current conduction through the spring strip can also be achieved.

[0093] However, according to the structure in the specific implementation, the two ends of each group of spring bars are connected to the body through their own connecting pieces, so that the connection between the spring bars and the body can be fixed by the connecting pieces to prevent the spring bars from breaking at the connection with the body, thereby ensuring that the electrical connection crown spring has a longer service life.

[0094] In addition, in the above-mentioned specific embodiment, the body is provided with engaging grooves at the two ends of the spring strip, and the engaging grooves are arranged in pairs, so that a engaging protrusion is formed between every two adjacent engaging grooves.

[0095] However, the present invention is not limited thereto, and the above-mentioned engaging groove may not be provided, and the corresponding engaging protrusion may not be formed, and the function of conducting current through the spring strip may also be achieved.

[0096] However, according to the structure in the specific implementation, the above-mentioned clamping groove is provided, and a clamping protrusion is formed between two adjacent clamping grooves, so that a matching structure can be provided on the outer surface of the male terminal or the inner surface of the female terminal accordingly, and then, the electrical connection crown spring is fixed by the above-mentioned clamping protrusion to prevent it from circumferential rotation or axial movement between the male terminal and the female terminal, thereby further ensuring the current stability.

[0097] In addition, in the above-mentioned specific embodiment, each engaging protrusion is bent from the inside of the cylindrical structure to the outside of the cylindrical structure.

[0098] However, the present invention is not limited thereto, and the above-mentioned clamping protrusion may not be bent, and the above-mentioned fixing function can also be achieved.

[0099] However, according to the structure in the specific implementation mode, each snap-in protrusion is bent from the inside of the cylindrical structure to the outside of the cylindrical structure, so that an angle is formed between each snap-in protrusion and the central axis of the cylindrical structure, so that the above-mentioned snap-in protrusion is more in line with the plug-in angle, thereby facilitating plug-in.

[0100] In addition, in the above-mentioned specific implementation, the angles formed between each clamping protrusion and the central axis of the cylindrical structure are equal.

[0101] However, it is not limited thereto, and the angles formed between each clamping protrusion and the central axis of the cylindrical structure may also be unequal, and the above-mentioned fixing function can also be achieved.

[0102] However, according to the structure in the specific implementation method, the angles formed between each snap-fitting protrusion and the central axis of the cylindrical structure are equal. Therefore, when the matching structure is set on the outer surface of the male terminal or the inner surface of the female terminal, it can be set according to a unified angle standard. Its manufacturing is simpler and more standardized, which is conducive to reducing the working time of processing and manufacturing and improving work efficiency.

[0103] In addition, in the above-mentioned specific embodiments, each of the strip springs is formed in a wave shape.

[0104] However, the present invention is not limited thereto. The above-mentioned strip springs may also be formed into long strips, which can also realize the current conduction function.

[0105] However, compared with setting each spring strip to be formed into a long strip, according to the structure in the specific implementation, each spring strip is set to be wavy, thereby increasing the contact area between the spring strip and the terminal surface, thereby further ensuring that the current has a larger stable flow.

[0106] In addition, in the above-mentioned specific embodiment, an opening extending along the length direction of the body is provided on the body.

[0107] However, the present invention is not limited thereto, and the above-mentioned opening may not be provided, and the current conduction function can also be achieved.

[0108] However, according to the structure in the specific implementation, the above-mentioned opening is provided, so that the diameter of the cylindrical structure can be adjusted through the opening, so that the electrical connection crown spring can adapt to electrical connection plug-ins of various models and sizes.

[0109] In addition, in the above specific implementations, each strip spring is a continuous structure.

[0110] However, the present invention is not limited thereto. The above-mentioned spring strips may not be formed into a continuous structure. For example, each spring strip actually includes two small segments. One end of one of the two small segments is connected to one end of the body, and one end of the other small segment is connected to the other end of the body. The two small segments are not connected, and the current conduction function can also be achieved.

[0111] However, according to the structure in the specific implementation, each spring strip is set to a continuous structure, thereby avoiding deformation of the spring strip, which is beneficial to maintaining the stability of the spring strip's conductivity and extending the overall service life of the electrical connection crown spring.

[0112] In addition, in the above-mentioned specific implementation, an anti-oxidation coating is applied on the outer surfaces of the body and the spring strip, respectively.

[0113] However, the present invention is not limited thereto, and the above-mentioned anti-oxidation coating may not be provided, and the current conducting function can also be achieved.

[0114] However, according to the structure in the specific implementation, an anti-oxidation coating is coated on the outer surfaces of the body and the spring strip respectively, so that the outer surface of the electrical connection crown spring can be protected by the anti-oxidation coating to prevent it from being oxidized by the external environment.

[0115] In addition, the electrical connection crown spring of the present invention can be formed by combining various structures of the above-mentioned embodiments, and can also exert the above-mentioned effects.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. 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 replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
