Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector plug, a connector, and an electronic device. Background Technology

[0002] Connectors are used to connect different electronic components in a circuit, thereby establishing signal paths between these components. Connectors are constantly evolving towards higher speeds and higher power densities, requiring smaller structural dimensions while meeting electrical performance requirements. In some related technologies, the unreasonable arrangement of the spring contacts in the connector plug results in a larger overall size for the connector plug. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a connector plug with a smaller structural size that does not affect its electrical performance.

[0005] An embodiment of this utility model also proposes a connector.

[0006] An embodiment of this utility model also proposes an electronic device.

[0007] The connector plug of this utility model embodiment includes: a plug housing; a first spring and a second spring, the first spring and the second spring being arranged at intervals within the plug housing; the first spring includes a connected first wiring segment and a first bent segment; the second spring includes a connected second wiring segment and a second bent segment; the first bent segment protrudes toward a side opposite to the second bent segment; the second bent segment protrudes toward a side opposite to the first bent segment; the distance between the first wiring segment and the second wiring segment is less than or equal to the maximum distance between the first bent segment and the second bent segment.

[0008] According to the connector plug of this utility model embodiment, since the distance between the first terminal segment and the second terminal segment is less than or equal to the maximum distance between the first bending segment and the second bending segment, the width of the first terminal segment and the second terminal segment can be smaller. The reduction in the width of the first terminal segment and the second terminal segment can provide clearance space for the wiring structure of the first terminal segment and the second terminal segment to install the cable. As a result, the width dimension of the plug shell fixing the position of the first terminal segment and the second terminal segment will also be reduced, and thus will not increase the width of the connector plug adjacent to the cable position. This allows the width of the connector plug in the vertical direction to be more consistent, thereby reducing the overall size of the connector plug.

[0009] In some embodiments, the first spring and the second spring are arranged symmetrically.

[0010] In some embodiments, the outer contours of both the first curved segment and the second curved segment are generally C-shaped.

[0011] In some embodiments, the distance between the first wiring segment and the second wiring segment is greater than or equal to 1 mm.

[0012] In some embodiments, the end of the first curved segment opposite to the first wiring segment and the end of the second curved segment opposite to the second wiring segment both have a scraping portion that makes electrical contact with the connector socket.

[0013] In some embodiments, the thickness of either the first spring or the second spring is S1, and the maximum size of the scraping portion is S2, wherein S2 ≤ 2S1.

[0014] In some embodiments, the plug housing has a receiving cavity, the inner wall of the receiving cavity has a limiting surface, and at least one of the first bending segment and the second bending segment includes a bending body and a protrusion, the protrusion being disposed at the position of the bending body closest to the limiting surface.

[0015] In some embodiments, the connector plug further includes a fixing block and a spacer. The fixing block and the spacer are both disposed inside the plug housing. The first wiring segment and the second wiring segment are both passed through the fixing block. The spacer is connected to the fixing block and divides the plug housing into multiple chambers. Each chamber is provided with a plurality of the first springs or the second springs.

[0016] Another embodiment of the connector of this utility model includes: a connector plug, wherein the connector plug is the connector plug described in any one of the embodiments of this utility model; and a connector socket, wherein the connector plug and the connector socket are inserted and mated.

[0017] According to the connector of this utility model embodiment, since the distance between the first terminal segment and the second terminal segment is less than or equal to the maximum distance between the first bending segment and the second bending segment, the width of the first terminal segment and the second terminal segment can be smaller. The reduction in the width of the first terminal segment and the second terminal segment can provide clearance space for the wiring structure of the first terminal segment and the second terminal segment to install the cable. As a result, the width dimension of the plug shell fixing the position of the first terminal segment and the second terminal segment will also be reduced, and thus the width of the connector plug adjacent to the cable position will not be increased. This allows the width of the connector plug in the vertical direction to be more consistent, thereby reducing the overall size of the connector plug.

[0018] The electronic device of this utility model includes the connector described in the embodiment of this utility model. Attached Figure Description

[0032] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following is a reference appendix. Figures 1 to 8 This invention describes connector plugs, connectors, and electronic devices according to embodiments of the present invention.

[0034] likeFigures 1 to 5 As shown, the connector plug 10 of this utility model embodiment includes: a plug shell 11, a first spring 121 and a second spring 122. The first spring 121 and the second spring 122 are arranged at intervals within the plug shell 11. The first spring 121 includes a first connecting segment 1211 and a first bent segment 1212 connected together. The second spring 122 includes a second connecting segment 1221 and a second bent segment 1222 connected together. The first bent segment 1212 protrudes toward the side opposite to the second bent segment 1222, and the second bent segment 1222 protrudes toward the side opposite to the first bent segment 1212. The distance between the first connecting segment 1211 and the second connecting segment 1221 is less than or equal to the maximum distance between the first bent segment 1212 and the second bent segment 1222.

[0035] According to the connector plug 10 of this utility model embodiment, since the distance between the first wiring segment 1211 and the second wiring segment 1221 is less than or equal to the maximum distance between the first bending segment 1212 and the second bending segment 1222, the width of the first wiring segment 1211 and the second wiring segment 1221 can be smaller. The reduction in the width of the first wiring segment 1211 and the second wiring segment 1221 can provide clearance space for the wiring structure of the first wiring segment 1211 and the second wiring segment 1221 to install the cable. As a result, the width dimension of the plug shell 11 fixing the position of the first wiring segment 1211 and the second wiring segment 1221 will also be reduced, and thus the width of the connector plug 10 adjacent to the cable position will not be increased. Therefore, the width of the connector plug 10 in the vertical direction can be made more consistent, thereby reducing the overall size of the connector plug 10.

[0036] In related technologies, the first bent segment 1212 of the connector plug 10 protrudes towards the side closer to the second bent segment 1222, and the second bent segment 1222 protrudes towards the side closer to the first bent segment 1212. In order to allow the first bent segment 1212 and the second bent segment 1222 to be spaced apart along the left and right direction of the plug shell 11, that is, to make structural clearance between the first bent segment 1212 and the second bent segment 1222, the spacing between the first wiring segment 1211 and the second wiring segment 1221 is usually designed to be large. Since the first wiring segment 1211 and the second wiring segment 1221 have a wire clamping and fixing structure with the cable, the width of the connector plug 10 near the cable position is large.

[0037] The connector plug 10 of this utility model, by having one of the first bending segment 1212 and the second bending segment 1222 protrude in the opposite direction to the other, can reduce the distance between the first wiring segment 1211 and the second wiring segment 1221 compared to the solutions in the related technologies mentioned above, without affecting the mechanical and electrical properties of the first spring 121 and the second spring 122.

[0038] Optionally, the first spring 121 and the second spring 122 are arranged symmetrically. For example... Figure 3 As shown, the first spring 121 and the second spring 122 are arranged in a mirror-symmetrical manner along the width direction of the plug housing 11. Therefore, when the connector plug 10 is inserted or removed, the force on both sides of the connector plug 10 in the width direction is consistent, that is, the force required to insert or remove the first spring 121 and the second spring 122 is roughly balanced, which can improve the user's feel when inserting or removing the plug, and make the connector plug 10 structurally regular and easy to process and manufacture.

[0039] like Figure 3 As shown, the outer contours of the first bending segment 1212 and the second bending segment 1222 are both generally C-shaped. When the first bending segment 1212 and the second bending segment 1222 undergo elastic deformation due to insertion and extraction forces, the radius of curvature of the C-shaped contour can be increased or decreased. This ensures reliable contact between the first spring 121 and the second spring 122 and the connector socket 20, and the structure is simple in design and easy to manufacture.

[0040] Optionally, such as Figure 5 As shown, the distance between the first segment 1211 and the second segment 1221 is greater than or equal to 1 mm. Through experimental research, the inventors of this invention discovered that when the distance between the first segment 1211 and the second segment 1221 is less than 1 mm, it leads to difficulties in installing the wire clamp structure of the first segment 1211 and the second segment 1221, and also causes signal crosstalk, affecting the electrical performance of the connector. Therefore, making the distance between the first segment 1211 and the second segment 1221 greater than or equal to 1 mm facilitates the assembly of the connector plug 10 and ensures that the connector plug 10 has good electrical performance.

[0041] In some embodiments, such as Figure 4 As shown, the end of the first bent segment 1212 opposite to the first wiring segment 1211 and the end of the second bent segment 1222 opposite to the second wiring segment 1221 both have a scraping portion 123 that makes electrical contact with the connector socket 20 or the circuit board 40. Exemplarily, the end of the first bent segment 1212 (second bent segment 1222) directly makes electrical contact with the connector socket 20. When the connector plug 10 is inserted or removed, the scraping portion 123 at the end of the first bent segment 1212 (second bent segment 1222) can scrape away dirt, oxide layers, and other debris from the electrical contact surface of the connector socket 20, which helps improve the stability of the electrical contact between the connector plug 10 and the socket. Furthermore, since the scraping portion 123 is located at the end of the first bent segment 1212 (second bent segment 1222), the spring contact will not have an unnecessary stub structure, avoiding the antenna radiation effect caused by the stub structure and the insertion loss problem of the connector. At the same time, it can improve the integrity of signal transmission and enhance the electrical performance of the connector.

[0042] Optionally, such as Figure 8 As shown, the thickness of either the first spring 121 or the second spring 122 is S1, and the maximum dimension of the scraping part 123 is S2, where S2 ≤ 2S1. It can be understood that the maximum dimension of the scraping part 123 is the maximum extension length of its outer wall surface. This prevents the spring from having redundant stub structures, avoiding the antenna radiation effect caused by stub structures and the insertion loss problem of the connector. Simultaneously, it improves the integrity of signal transmission and enhances the electrical performance of the connector.

[0043] For example, the scraping part 123 has a rounded chamfer, which reduces the resistance when the scraping part 123 slides relative to the electrical contact surface of the connector socket 20, thereby improving the user's feel when plugging and unplugging. The chamfer radius can be selected according to the thickness of the spring (first spring 121 or second spring 122).

[0044] In other examples, such as Figure 8 As shown, the scraping part 123 has a flat surface, that is, the contact surface between the scraping part 123 and the connector socket 20 is a plane.

[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, the plug housing 11 has a receiving cavity 111, and the inner wall of the receiving cavity 111 has a limiting surface 112. At least one of the first bending section 1212 and the second bending section 1222 includes a bending body 124 and a protrusion 125. The protrusion 125 is disposed at the position of the bending body 124 closest to the limiting surface 112.

[0046] Since the convex 125 is located at the position closest to the limiting surface 112 of the bending body 124, when the bending body 124 is deformed by pressure, the convex 125 can contact the limiting surface 112 first, thereby limiting the bending body 124 from continuing to deform in the direction of the limiting surface 112, so as to prevent the problem of TDR impedance runaway caused by other positions of the bending body 124 approaching the limiting surface 112.

[0047] It is understandable that in related technologies, when the connector plug 10 is inserted into the connector socket 20, various factors may cause inconsistencies in the final shape and position of different spring contacts, resulting in random differences in the dielectric distribution around each spring contact, which in turn makes it difficult to control the TDR impedance of the entire spring contact area. However, the connector plug 10 of this embodiment can use the protrusion 125 to positionally constrain the bending body 124, so that the TDR impedance of the bending area of ​​each spring contact tends to be consistent, thereby improving the electrical performance of the connector plug 10.

[0048] For example, the outer contour of the convex hull 125 is hemispherical, so that when the convex hull 125 abuts against the limiting surface 112, the contact area between the convex hull 125 and the limiting surface 112 can be smaller, thereby further reducing the TDR impedance sensitivity of the spring.

[0049] For example, the outer contour of the bending body 124 is generally C-shaped, and the protrusion 125 is located in the middle of the C-shaped bending body 124, thereby ensuring that the spring piece after insertion only contacts the limiting surface 112 at the protrusion 125 position.

[0050] For example, the convex hull 125 and the curved body 124 can be integrally formed. Alternatively, the convex hull 125 can be welded onto the curved body 124.

[0051] In some embodiments, such as Figure 6 and Figure 7 As shown, the connector plug 10 also includes a fixing block 13 and a spacer 14. Both the fixing block 13 and the spacer 14 are disposed inside the plug housing 11. The first wiring segment 1211 and the second wiring segment 1221 are both inserted through the fixing block 13. The spacer 14 is connected to the fixing block 13 and divides the plug housing 11 into multiple chambers 113. Each chamber 113 is provided with several first spring contacts 121 or second spring contacts 122. Thus, the spacer 14 can shield and isolate the first spring contacts 121 or second spring contacts 122 in different chambers 113 to prevent signal crosstalk between the first spring contacts 121 or second spring contacts 122 in adjacent chambers 113.

[0052] For example, the fixing block 13 is formed by injection molding, which can ensure the isolation and shielding effect of the first spring 121 and the second spring 122, and is conducive to improving the structural strength after the springs (first spring 121 and second spring 122) are connected to the fixing block 13.

[0053] like Figure 1 As shown, another embodiment of the connector of this utility model includes a connector plug 10 and a connector socket 20. The connector plug 10 is the connector plug 10 of this utility model, and the connector plug 10 and the connector socket 20 are plugged into each other. The connector socket 20 is soldered onto the circuit board 40. One end of the connector plug 10 is connected to a cable, and the other end of the connector plug 10 is inserted into the connector socket 20. The technical advantages of the connector of this utility model embodiment are the same as the technical advantages of the connector plug 10 of the above embodiment, and will not be repeated here.
