Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular, to a connector plug and a connector. Background Art

[0002] Connectors are used to connect different electronic components in a circuit, thereby establishing a signal path between the electronic components. With the progress of technology, the data exchange between electronic components is increasing continuously, the signal rate is getting faster and faster, and the signal transmission bandwidth is also increasing continuously. Among them, the electrical properties of the connector such as TDR impedance, return loss, insertion loss, and crosstalk have a crucial impact on the quality of signal transmission. In the related art, the structural design of the elastic piece of the connector is unreasonable, and the elastic piece is highly sensitive to the TDR impedance, which easily causes the TDR impedance of the elastic piece to get out of control, thereby affecting the electrical performance of the connector. Summary of the Invention

[0003] The present invention is made based on the inventor's discovery and recognition of the following facts and problems:

[0004] In the related art, the degree of bending of the elastic piece is different each time the connector plug is inserted and removed. As a result, the elastic piece may come into contact with the inner wall of the plug housing, or have a certain distance from the inner wall of the plug housing. The plug housing is generally a plastic housing, and the medium around the elastic piece consists of air and plastic. The dielectric constants of air and plastic are quite different. Therefore, when the medium near the elastic piece changes from air to plastic, it will cause a sharp drop in the TDR impedance, and thus the TDR impedance differences of the elastic pieces at different positions are relatively large, affecting the electrical performance of the connector plug.

[0005] The present invention aims to solve at least one of the technical problems in the related art to some extent.

[0006] To this end, an embodiment of the present invention provides a connector plug, which can reduce the TDR impedance sensitivity of the elastic piece and is beneficial to improving the electrical performance of the connector plug.

[0007] An embodiment of the present invention also provides a connector.

[0009] According to the connector plug of the embodiment of the present invention, when the connector plug is inserted into the connector socket, the bending section will undergo a certain elastic deformation. Since a stop block is provided on one of the bending section and the limiting surface, and the stop block is arranged facing the other of the bending section and the limiting surface, the deformed bending section can maintain a certain distance from the limiting surface under the constraint of the stop block. Therefore, when the connector plug is plugged in or out, it can ensure that the TDR impedance of the bending area of ​​each spring piece tends to be consistent, so as to reduce the TDR impedance sensitivity of the spring piece and facilitate TDR impedance control, which is beneficial to improving the electrical performance of the connector plug.

[0010] In some embodiments, the stop block is arranged at a position of the curved section that is closest to the limiting surface.

[0014] In some embodiments, the stop block is arranged on the limiting surface, and the distance between the stop block and the bending section is smaller than the distance between any position of the bending section and the limiting surface.

[0015] In some embodiments, the stop block is a cubic structure.

[0016] In some embodiments, the shortest distance between the curved section and the limiting surface is greater than or equal to 0.08 mm.

[0017] In some embodiments, the outer profile of the curved section is generally C-shaped.

[0018] In some embodiments, the end of the spring sheet has a scraping portion for electrically contacting the connector socket or the circuit board.

[0019] In some embodiments, the thickness of the spring sheet is S1, and the maximum size of the scraping portion is S2, wherein S2≤2S1.

[0020] In some embodiments, the scraping portion has a rounded chamfer or a straight surface.

[0021] In some embodiments, the spring sheet further includes a weakening portion, wherein the weakening portion is disposed on the bending segment, and a thickness of the weakening portion is smaller than a thickness of a remaining portion of the bending segment.

[0022] In some embodiments, there are a plurality of weakening portions, and the plurality of weakening portions are arranged at intervals along the extension direction of the curved segment.

[0023] In some embodiments, the spring clip includes a first spring clip and a second spring clip, the first spring clip and the second spring clip are arranged at intervals in the plug shell, the first spring clip includes a connected first wiring segment and a first bending segment, the second spring clip includes a connected second wiring segment and a second bending segment, the first bending segment protrudes toward a side away from the second bending segment, the second bending segment protrudes toward a side away from the first bending segment, and the spacing between the first wiring segment and the second wiring segment is less than or equal to the maximum spacing between the first bending segment and the second bending segment.

[0024] A connector according to another embodiment of the present invention includes the connector plug according to any one of the embodiments of the present invention.

[0025] According to the connector of an embodiment of the present invention, when the connector plug is inserted into the connector socket, the bending section will undergo a certain elastic deformation. Since a stop block is provided on one of the bending section and the limiting surface, and the stop block is arranged facing the other of the bending section and the limiting surface, the deformed bending section can maintain a certain distance from the limiting surface under the constraint of the stop block. Therefore, when the connector plug is plugged in or out, the TDR impedance of the bending area of ​​each spring piece can be ensured to be consistent, so as to reduce the TDR impedance sensitivity of the spring piece and facilitate TDR impedance control, which is beneficial to improving the electrical performance of the connector.

[0042] The embodiments of the present invention will be described in detail below. The 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.

[0043] The following refers to the attached Figures 1 to 11 Describe the connector plug and the connector of the embodiment of the present invention.

[0044] As Figures 1 to 6 shown, the connector plug 100 of the embodiment of the present invention includes: a plug housing 101 and an elastic piece 102. An accommodating cavity 1011 is provided in the plug housing 101. The inner wall of the accommodating cavity 1011 has a limiting surface 1012. The elastic piece 102 includes a bending section 1021. The bending section 1021 is arranged in the accommodating cavity 1011 and is used for electrically connecting with the connector socket 200. The bending section 1021 protrudes towards the limiting surface 1012. A stopper 103 is provided on one of the bending section 1021 and the limiting surface 1012. The stopper 103 is arranged facing the other of the bending section 1021 and the limiting surface 1012.

[0045] According to an embodiment of the present invention, for the connector plug 100, when the connector plug 100 is inserted into the connector socket 200, the bending section 1021 will undergo a certain elastic deformation. Since a stop block 103 is provided on one of the bending section 1021 and the limiting surface 1012, and the stop block 103 is arranged facing the other of the bending section 1021 and the limiting surface 1012, the deformed bending section 1021 can maintain a certain distance from the limiting surface 1012 under the constraint of the stop block 103. Thus, when the connector plug 100 is inserted and removed, the TDR impedance of the bending regions of the respective elastic pieces 102 can be made to tend to be consistent, so as to reduce the TDR impedance sensitivity of the elastic pieces 102 and facilitate TDR impedance control, thereby being conducive to improving the electrical performance of the connector plug 100.

[0046] It can be understood that when a connector plug in the related art is inserted into a connector socket, due to various factors, the final shapes and positions maintained by different elastic pieces may be inconsistent, resulting in random differences in the dielectric distribution around each elastic piece, and further making it difficult to control the TDR impedance of the entire region of the elastic pieces. However, for the connector plug 100 according to the embodiment of the present invention, the position of the elastic piece 102 can be constrained by the stop block 103, so that the TDR impedance of the bending regions of the respective elastic pieces 102 tends to be consistent, thereby being conducive to improving the electrical performance of the connector plug 100.

[0047] Optionally, as Figure 4 and Figure 6 shown, the stop block 103 is provided at the position on the bending section 1021 closest to the limiting surface 1012. Since the stop block 103 is provided at the position on the bending section 1021 closest to the limiting surface 1012, when the bending section 1021 is deformed under pressure, the stop block 103 can come into contact with the limiting surface 1012 first, thereby restricting the bending section 1021 from deforming further in the direction towards the limiting surface 1012, so as to prevent the problem of out-of-control TDR impedance caused by other positions of the bending section 1021 approaching the limiting surface 1012.

[0048] As Figure 4 shown, the stop block 103 is a convex hull, and the convex hull is provided on the side of the bending section 1021 facing the limiting surface 1012. The convex hull structure has little impact on the overall structure of the bending section 1021 and has almost no impact on the TDR impedance, so as to reduce the TDR impedance sensitivity of the elastic piece 102.

[0049] Exemplarily, the outer contour of the convex hull is hemispherical. Thus, when the convex hull abuts against the limiting surface 1012, the contact area between the convex hull and the limiting surface 1012 can be made smaller, thereby further reducing the TDR impedance sensitivity of the elastic piece 102.

[0050] Exemplarily, the outer contour of the bending section 1021 is generally C-shaped, and the convex bump is arranged at the middle position of the C-shaped bending section 1021, so that it can be ensured that the elastic piece 102 only contacts the limiting surface 1012 at the position of the convex bump after insertion.

[0051] For example, the convex bump and the bending section 1021 can be integrally formed. For another example, the convex bump can be arranged on the bending section 1021 by welding.

[0052] Optionally, as Figure 4 shown, a groove 1022 is provided on the side of the bending section 1021 facing away from the convex bump. It can be understood that the convex bump is formed by stamping, and thus the groove 1022 is formed on the side of the bending section 1021 facing away from the convex bump. By adopting the above structural form for the elastic piece 102 in the connector plug 100 of the embodiment of the present invention, it is convenient for the processing and manufacturing of the elastic piece 102, and has little influence on the structure of the elastic piece 102 and the TDR impedance.

[0053] In some other embodiments, as Figure 6 shown, the stop block 103 is arranged on the limiting surface 1012, and the distance between the stop block 103 and the bending section 1021 is less than the distance between any position of the bending section 1021 and the limiting surface 1012. When the bending section 1021 is deformed under pressure, the stop block 103 can contact the bending section 1021 first, so as to limit the further deformation of the bending section 1021 in the direction towards the limiting surface 1012, and prevent the problem of out-of-control TDR impedance caused by other positions of the bending section 1021 approaching the limiting surface 1012.

[0054] Optionally, the stop block 103 is of a cube structure, which is convenient for the processing and manufacturing of the stop block 103 and can improve the stability when the stop block 103 contacts the bending section 1021.

[0055] The material of the plug housing 101 can be plastic, and at this time the limiting surface 1012 is a plastic wall surface. By arranging the stop block 103 on the plastic wall surface and making the bending section 1021 abut against the stop block 103 in the connector plug 100 of the embodiment of the present invention, so that the bending section 1021 keeps a certain distance from the plastic wall surface, thus the problem of sharp drop in TDR impedance caused by the bending section 1021 approaching the plastic wall surface can be avoided.

[0056] For example, as Figure 6 shown, the outer contour of the bending section 1021 is generally C-shaped, the middle position of the C-shaped bending section 1021 contacts the stop block 103, the stop block 103 is integrally formed with the insertion shell, and the size of the stop block 103 is small. Therefore, the influence of the stop block 103 on the TDR impedance of the bending section 1021 is limited, so that the electrical performance of the connector plug 100 can be ensured, and the processing and manufacturing are simple.

[0057] Optionally, as shown in Figure 4 and Figure 6 shown, the shortest distance between the bending section 1021 and the limiting surface 1012 is greater than or equal to 0.08 mm. As shown in Figure 10 shown, the inventors of the present application found through experimental research that when the shortest distance between the bending section 1021 and the limiting surface 1012 is greater than or equal to 0.08 mm, the distance between the bending section 1021 and the limiting surface 1012 has little influence on the TDR impedance. Therefore, limiting the shortest distance between the bending section 1021 and the limiting surface 1012 to be greater than or equal to 0.08 mm can reduce the TDR impedance sensitivity.

[0058] In some embodiments, as shown in Figure 6 and Figure 9 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 section 1021. 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.

[0059] That is to say, the area of the elastic piece 102 corresponding to the scraping portion 1023 can be curved or straight.

[0060] In one example, the end of the bending section 1021 is directly in electrical contact with the connector socket 200, and when the elastic piece 102 is inserted and removed, the scraping portion 1023 at the end of the bending section 1021 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, it can prevent the elastic piece 102 from having redundant structures such as stubs, avoiding the antenna radiation effect generated by the stub structure and the problem of insertion loss of the connector. At the same time, it can improve the integrity of signal transmission and enhance the electrical performance of the connector.

[0061] Optionally, as shown in Figure 11 shown, the thickness of the elastic piece 102 is S1, and the maximum size of the scraping portion 1023 is S2, where S2 ≤ 2S1. It can be understood that the maximum size of the scraping portion 1023 is the maximum extension length of the outer wall surface of the scraping portion 1023.

[0062] This can prevent the end of the elastic piece 102 from having redundant structures such as stubs, avoiding the antenna radiation effect generated by the stub structure and the problem of insertion loss of the connector. At the same time, it can improve the integrity of signal transmission and enhance the electrical performance of the connector.

[0063] Optionally, as shown in Figure 9As shown, the scraping part 1023 has an arc chamfer. Thereby, the resistance when the scraping part 1023 slides relative to the electrical contact surface of the connector socket 200 can be reduced, and the feel of the user when plugging and unplugging can be improved. The chamfer radius of the arc chamfer can be selected according to the thickness of the elastic piece 102.

[0064] In other examples, such as Figure 11 As shown, the scraping part 1023 has a flat surface, that is, the contact surface between the scraping part 1023 and the connector socket 200 is a plane.

[0065] Optionally, such as Figure 6 As shown, the elastic piece 102 further includes a weakening part 1024, and the weakening part 1024 is arranged on the bending section 1021, and the thickness of the weakening part 1024 is less than the thickness of the rest of the bending section 1021.

[0066] It can be understood that to meet the specific electrical performance requirements of the connector, the elastic piece 102 needs to be designed into a specific structure, and it is inevitable to bring mechanical performance problems. If the elastic force of a single elastic piece 102 is large, then the insertion feel of the connector is not good, and even the circuit board 400 is easily damaged. In order to reduce the elastic force of the elastic piece 102, it is necessary to reduce the width or thickness of the elastic piece 102. In the connector plug 100 of the embodiment of the present invention, by arranging the weakening part 1024 of the elastic piece 102 on the bending section 1021, the elastic force of the elastic piece 102 can be reduced, the feel of the user when plugging and unplugging the connector can be improved, and the influence on the electrical performance of the elastic piece 102 is small.

[0067] The inventor of the present invention found through experimental research that the overall elastic force of the elastic piece 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 elastic piece 102. It can be known from the elastic force calculation formula of the elastic piece 102 that the elastic force of the elastic piece 102 has a linear relationship with the width, and the elastic force of the elastic piece 102 has a cubic relationship with the thickness, that is, to reduce the same elastic force, the change amount of the thickness of the elastic force of the elastic piece 102 is much smaller than the change amount of the width. Therefore, in the connector plug 100 of the embodiment of the present invention, by slightly reducing the thickness of the position of the weakening part 1024, the elastic force of the elastic piece 102 can be greatly reduced, and it is not easily recognized by high-frequency signals, so as not to affect the electrical performance of the elastic piece 102.

[0068] Exemplarily, such as Figure 8 As shown, there are multiple weakening parts 1024, and the multiple weakening parts 1024 are arranged at intervals along the extending direction of the bending section 1021. Thereby, the elastic force of the elastic piece 102 can be further reduced, and the feel of the user when plugging and unplugging the connector can be improved.

[0069] The elastic piece 102 can be a high-speed elastic piece or a non-high-speed elastic piece. That is, the high-speed elastic piece is used to transmit high-speed signals, and the non-high-speed elastic piece is used to transmit low-speed signals or supply power.

[0070] In one example, the elastic piece 102 is a low-speed elastic piece, and the width of the weakening part 1024 can be smaller than the width of the rest of the bending section 1021, so that the normal transmission of low-speed signals will not be affected, and the overall elasticity of the elastic piece 102 can be reduced, thereby further improving the feel when the user plugs and unpluggs the connector.

[0071] In some embodiments, as Figure 7 shown, the elastic piece 102 includes a first elastic piece 112 and a second elastic piece 122. The first elastic piece 112 and the second elastic piece 122 are arranged at intervals in the plug housing 101. The first elastic piece 112 includes a connected first wiring section 1122 and a first bending section 1121. The second elastic piece 122 includes a connected second wiring section 1222 and a second bending section 1221. It can be understood that the first wiring section 1122 and the second wiring section 1222 are used to connect with the cable 300, and the first bending section 1121 and the second bending section 1221 are used to contact the electrical contact surface of the socket.

[0072] As Figure 7 shown, the first bending section 1121 protrudes toward the side away from the second bending section 1221, and the second bending section 1221 protrudes toward the side away from the first bending section 1121, that is, the first bending section 1121 and the second bending section 1221 protrude in opposite directions, and the distance between the first wiring section 1122 and the second wiring section 1222 is less than or equal to the maximum distance between the first bending section 1121 and the second bending section 1221.

[0073] It can be understood that since the distance between the first wiring section 1122 and the second wiring section 1222 is less than or equal to the maximum distance between the first bending section 1121 and the second bending section 1221, the widths of the first wiring section 1122 and the second wiring section 1222 can be made smaller. The reduction in the widths of the first wiring section 1122 and the second wiring section 1222 can provide a clearance space for the wiring structure for installing the cable 300 on the first wiring section 1122 and the second wiring section 1222. Thus, the width dimension of the plug housing 101 for fixing the positions of the first wiring section 1122 and the second wiring section 1222 will also be reduced, and the width of the connector plug 100 adjacent to the cable 300 will not be increased, so that the width of the connector plug 100 in the up and down direction can tend to be consistent, thereby reducing the overall size of the connector plug 100.

[0074] Optionally, as Figure 7As shown, the first elastic piece 112 and the second elastic piece 122 are symmetrically arranged. It can be understood that the first elastic piece 112 and the second elastic piece 122 are mirror-symmetrically arranged along the width direction of the plug housing 101. Thus, when the connector plug 100 is inserted and removed, the forces on both sides in the width direction of the connector plug 100 can be made consistent, that is, the forces required to insert and remove the first elastic piece 112 and the second elastic piece 122 are generally balanced, thereby improving the user's feel during insertion and removal, and making the structure of the connector plug 100 regular and convenient for processing and manufacturing.

[0075] 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 inserted and mated with each other. As Figure 1 shown, 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.

[0076] For the connector according to the embodiment of the present invention, when the connector plug 100 is inserted into the connector socket 200, the bending section 1021 will undergo a certain elastic deformation. Since a stop block 103 is provided on one of the bending section 1021 and the limiting surface 1012, and the stop block 103 is arranged facing the other of the bending section 1021 and the limiting surface 1012, the deformed bending section 1021 can maintain a certain distance from the limiting surface 1012 under the constraint of the stop block 103. Thus, when the connector plug 100 is inserted and removed, it can be ensured that the TDR impedance of the bending regions of each elastic piece 102 tends to be consistent, so as to reduce the TDR impedance sensitivity of the elastic piece 102 and facilitate TDR impedance control, thereby being beneficial to improving the electrical performance of the connector.
