[0036] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0037] Reference will be made below to the attached Figures 1 to 9 to describe the connector plug and the connector of the embodiments of the present invention.

[0038] As Figures 1 to 6 shown, the connector plug 100 of the embodiment of the present invention includes: a plug housing 101 and a spring piece 102. The spring piece 102 is disposed within the plug housing 101. The spring piece 102 includes a spring piece body 1021. The spring piece body 1021 has a weakened portion 1022. The thickness of the weakened portion 1022 is less than the thickness of the area of the spring piece body 1021 adjacent to the weakened portion 1022. It should be noted that the area of the spring piece body 1021 adjacent to the weakened portion 1022 is the area where the spring piece 102 can undergo elastic deformation when the connector plug 100 is inserted and removed. It can be understood that the area of the spring piece body 1021 adjacent to the weakened portion 1022 is not the area where the spring piece 102 is connected to the cable 300.

[0039] By providing the weakened portion 1022 on the spring piece body 1021 of the connector plug 100 of the embodiment of the present invention, and the thickness of the weakened portion 1022 is less than the thickness of the area of the spring piece body 1021 adjacent to the weakened portion 1022, the elastic force of the spring piece 102 can be greatly reduced, and it is not easily recognized by high-frequency signals, thereby not affecting the electrical performance of the spring piece 102.

[0040] It can be understood that in order to meet the specific electrical performance requirements of the connector, the spring piece 102 needs to be designed into a specific structure, which inevitably brings mechanical performance problems. If the elastic force of a single spring piece 102 is large, then the insertion feel of the connector is poor, and it is even easy to damage the circuit board 400. In order to reduce the elastic force of the spring piece 102, it is necessary to reduce the width or thickness of the spring piece 102. By disposing the weakened portion 1022 of the spring piece 102 on the spring piece body 1021 of the connector plug 100 of the embodiment of the present invention, the elastic force of the spring piece 102 can be reduced, the feel of the user when inserting and removing the connector can be improved, and the influence on the electrical performance of the spring piece 102 is small.

[0041] The inventor of the present invention has found through experimental research that the overall elastic force of the spring 102 is related to the material, width, thickness, and length of the metal. When the material and length are optimized to the extreme, the purpose of reducing the elastic force can only be achieved by changing the thickness and width of the spring 102. It can be seen from the elastic force calculation formula of the spring 102 that the elastic force of the spring 102 is linearly related to the width, and the elastic force of the spring 102 is cubically related to the thickness, that is, to reduce the same elastic force, the change in the thickness of the spring 102 is much smaller than the change in the width. Therefore, the connector plug 100 of the embodiment of the present invention can greatly reduce the elastic force of the spring 102 by slightly reducing the thickness at the weakening portion 1022, and is not easily recognized by high-frequency signals, so that the electrical performance of the spring 102 is not affected.

[0042] Alternatively, if Figure 4 and Figure 6 As shown, the spring body 1021 has a bent portion 10211, and the weakening portion 1022 is disposed on the bent portion 10211. It is understandable that when the spring 102 contacts the connector socket 200, the bent portion 10211 will undergo a large elastic deformation. Since the weakening portion 1022 is disposed on the bent portion 10211, the elastic force on the bent portion 10211 can be greatly reduced, thereby facilitating the user to plug and unplug the connector plug 100.

[0043] The first end of the spring sheet 102 is used to connect the cable 300, the second end of the spring sheet 102 is used to connect with the connector socket 200, and the weakening portion 1022 is arranged adjacent to the second end of the spring sheet 102. In this way, the elastic force exerted on the spring sheet 102 when it contacts the connector socket 200 or the circuit board 400 can be further reduced, and the electrical performance of the connector plug 100 is less affected.

[0044] For example, Figure 6 As shown, the spring piece 102 includes a connected wiring portion 1025 and a bent portion 10211 , the wiring portion 1025 is connected to the cable 300 , the outer contour of the bent portion 10211 is generally C-shaped, and the weakened portion 1022 is arranged at one end of the bent portion 10211 close to the connector socket 200 .

[0045] Alternatively, if Figure 7 As shown, there are multiple weakening parts 1022, and the multiple weakening parts 1022 are arranged at intervals along the extension direction of the spring body 1021. In this way, the elastic force of the spring 102 can be further reduced, and the user's hand feeling when plugging and unplugging the connector can be improved. Among them, the distance between adjacent weakening parts 1022 can be designed according to the working frequency of the spring 102 or the manufacturing process of the spring 102, and the present invention is not limited to this.

[0046] like Figure 7As shown, multiple positions on the C-shaped bending portion 10211 have weakening portions 1022, and the multiple weakening portions 1022 are arranged at intervals along the extending direction of the bending portion 10211.

[0047] In some embodiments, as Figure 7 shown, the elastic piece 102 includes a high-speed elastic piece 112 for transmitting high-speed signals. The high-speed elastic piece 112 includes a first elastic piece body 1121, and the first elastic piece body 1121 has a first weakening portion 1122. The thickness of the first weakening portion 1122 is less than the thickness of the area of the first elastic piece body 1121 adjacent to the first weakening portion 1122. By reducing the thickness at the position of the first weakening portion 1122, the connector plug 100 of the embodiment of the present invention can not only reduce the elastic force of the high-speed elastic piece 112, but also is not easily recognized by high-frequency signals, thus not affecting the electrical performance of the high-speed elastic piece 112.

[0048] The wavelength corresponding to the maximum operating frequency of the connector plug 100 is A1, and the length of the first weakening portion 1122 is A2, where 0.2 ≤ A2 / A1 ≤ 0.7. For example, A2 / A1 can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7. Through experimental research, the inventors of the present application found that when the first weakening portion 1122 is designed with the above parameter range, the high-speed signals transmitted by the high-speed elastic piece 112 can be prevented from being recognized, so as to avoid adverse effects on the electrical performance of the connector, and the elastic force of the high-speed elastic piece 112 can be reduced to make the use effect of the high-speed elastic piece 112 optimal.

[0049] Optionally, as Figure 7 shown, there are multiple first weakening portions 1122, and the multiple first weakening portions 1122 are arranged at intervals along the extending direction of the first elastic piece body 1121. The wavelength corresponding to the maximum operating frequency of the connector plug 100 is A1, and the distance between two adjacent first weakening portions 1122 is A3, where 0.2 ≤ A3 / A1. For example, A2 / A1 can be 0.2, 0.3, 0.4, 0.5. Through experimental research, the inventors of the present application found that when two adjacent first weakening portions 1122 are designed with the above parameter range, the stability of the electrical contact between the high-speed elastic piece 112 and the connector socket 200 can be ensured, and adverse effects on the electrical performance of the connector can be avoided.

[0050] In some embodiments, as Figure 8As shown, the elastic piece 102 includes a non-high-speed elastic piece 122. The non-high-speed elastic piece 122 is used to transmit low-speed signals or supply power. The non-high-speed elastic piece 122 includes a second elastic piece body 1221. The second elastic piece body 1221 has a second weakening portion 1222. The thickness of the second weakening portion 1222 is less than the thickness of the area of the second elastic piece body 1221 adjacent to the second weakening portion 1222. By reducing the thickness at the position of the second weakening portion 1222, the connector plug 100 according to the embodiment of the present invention can reduce the elastic force of the high-speed elastic piece 112 and is not easily recognized by high-frequency signals, thus not affecting the electrical performance of the non-high-speed elastic piece 122.

[0051] As Figure 8 shown, the thickness of the second elastic piece body 1221 is B1, and the thickness of the second weakening portion 1222 is B2, where 1 / 10 ≤ B2 / B1 ≤ 19 / 20. For example, B2 / B1 can be 0.1, 0.3, 0.5, 0.7, 0.9, 0.95. The inventors of the present application found through experimental research that when the thicknesses of the second elastic piece body 1221 and the second weakening portion 1222 are designed within the above parameter range, the elastic force of the non-high-speed elastic piece 122 can be reduced, and the structural strength of the non-high-speed elastic piece 122 and the stability of the electrical contact between the non-high-speed elastic piece 122 and the connector socket 200 can be ensured.

[0052] Optionally, as Figure 8 shown, the width of the second weakening portion 1222 is less than the width of the area of the second elastic piece body 1221 adjacent to the second weakening portion 1222. It can be understood that the non-high-speed elastic piece 122 reduces its elastic force by reducing the width of the second weakening portion 1222. Since the non-high-speed elastic piece 122 only transmits low-frequency signals, reducing the width of the second weakening portion 1222 will not overly affect the electrical performance of the non-high-speed elastic piece 122.

[0053] As Figure 8 shown, the width of the area of the second elastic piece body 1221 adjacent to the second weakening portion 1222 is C1, and the width of the second weakening portion 1222 is C2, where 5 / 8 ≤ C2 / C1 ≤ 3 / 4. For example, C2 / C1 can be 0.62, 0.68, 0.7, 0.73, 0.75. The inventors of the present application found through experimental research that when the widths of the second elastic piece body 1221 and the second weakening portion 1222 are designed within the above parameter range, the elastic force of the non-high-speed elastic piece 122 can be reduced, and the structural strength of the non-high-speed elastic piece 122 and the stability of the electrical contact between the non-high-speed elastic piece 122 and the connector socket 200 can be ensured.

[0054] Optionally, as Figure 6As shown, the end of the elastic piece 102 has a scraping portion 1023 that is in electrical contact with the connector socket 200 or the circuit board 400. For example, the end of the elastic piece 102 is the end of the bending portion 10211. Another example is that the end of the elastic piece 102 has a straight section, and the scraping portion 1023 is provided at the end of the straight section.

[0055] It can be understood that when the elastic piece 102 is inserted and removed, the scraping portion 1023 at the end of the elastic piece 102 can scrape off dirt, oxide layers and other debris on the electrical contact surface of the connector socket 200, which is beneficial to improving the stability when the connector plug 100 and the socket are in electrical contact. In addition, since the scraping portion 1023 is provided at the end of the elastic piece 102, the elastic piece 102 will not have redundant structures such as Stub, avoiding the antenna radiation effect generated by the Stub structure and the problem of insertion loss of the connector. At the same time, the integrity of signal transmission can be improved, and the electrical performance of the connector can be enhanced.

[0056] Optionally, as Figure 9 shown, the thickness of the elastic piece 102 is S1, and the maximum dimension of the scraping portion 1023 is S2, where S2 ≤ 2S1. It can be understood that the maximum dimension of the scraping portion 1023 is the maximum extension length of the outer wall surface of the scraping portion 1023.

[0057] This can prevent the end of the elastic piece 102 from having redundant structures such as Stub, avoiding the antenna radiation effect generated by the Stub structure and the problem of insertion loss of the connector. At the same time, the integrity of signal transmission can be improved, and the electrical performance of the connector can be enhanced.

[0058] Optionally, the scraping portion 1023 has a circular arc chamfer. This can reduce the resistance when the scraping portion 1023 slides relative to the electrical contact surface of the connector socket 200 and improve the feel when the user inserts and removes. The chamfer radius of the circular arc chamfer can be selected according to the thickness of the elastic piece 102.

[0059] In other examples, as Figure 9 shown, the scraping portion 1023 has a flat surface, that is, the contact surface between the scraping portion 1023 and the connector socket 200 is a plane.

[0060] In some embodiments, as Figure 4 shown, the plug housing 101 is provided with a receiving cavity 1011, the inner wall of the receiving cavity 1011 has a limiting surface 1012, the elastic piece body 1021 includes a buckling portion and a convex hull 1024, and the convex hull 1024 is arranged at the position where the buckling portion is closest to the limiting surface 1012.

[0061] Since the convex hull 1024 is disposed at the position closest to the limiting surface 1012 of the buckling part, when the buckling part is compressed and deformed, the convex hull 1024 can come into contact with the limiting surface 1012 first, thereby restricting the buckling part from continuing to deform in the direction towards the limiting surface 1012 to prevent the problem of out-of-control TDR impedance caused by other positions of the buckling part approaching the limiting surface 1012.

[0062] It can be understood that when the connector plug 100 in the related art is inserted into the connector socket 200, affected by various factors, the finally maintained shapes and positions of different signal elastic pieces 102 may be inconsistent, resulting in random differences in the dielectric distribution around each signal elastic piece 102, and further making it difficult to control the TDR impedance of the entire area of the signal elastic piece 102. The connector plug 100 of the embodiment of the present invention can positionally constrain the buckling part through the convex hull 1024, so that the TDR impedance of the bending areas of the respective signal elastic pieces 102 tends to be consistent, which is beneficial to improving the electrical performance of the connector plug 100.

[0063] Exemplarily, as Figure 4 shown, the outer contour of the convex hull 1024 is hemispherical. Thus, when the convex hull 1024 abuts against the limiting surface 1012, the contact area between the convex hull 1024 and the limiting surface 1012 can be made smaller, thereby further reducing the TDR impedance sensitivity of the signal elastic piece 102.

[0064] Exemplarily, as Figure 4 shown, the outer contour of the buckling part is generally C-shaped, and the convex hull 1024 is disposed at the middle position of the C-shaped buckling part, thereby ensuring that the signal elastic piece 102 after insertion only contacts the limiting surface 1012 at the position of the convex hull 1024.

[0065] For example, the convex hull 1024 and the buckling part can be integrally formed. Or, for example, the convex hull 1024 can be disposed on the buckling part by welding.

[0066] As Figure 1 shown, a connector according to another embodiment of the present invention includes a connector plug 100 and a connector socket 200. The connector plug 100 is the connector plug 100 of the embodiment of the present invention, and the connector plug 100 and the connector socket 200 are in pluggable cooperation. The connector socket 200 is welded to the circuit board 400. One end of the connector plug 100 is connected to the cable 300, and the other end of the connector plug 100 is inserted into the connector socket 200.

[0067] According to the connector of an embodiment of the present invention, by providing a weakening portion 1022 on the elastic piece body 1021, and the thickness of the weakening portion 1022 is smaller than the thickness of the area of the elastic piece body 1021 adjacent to the weakening portion 1022, the elastic force of the elastic piece 102 can be greatly reduced, and it is not easily recognized by high-frequency signals, so that the electrical performance of the elastic piece 102 will not be affected.
