Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a switching device and a data cable. Background Art

[0002] At present, the electrical connectors used in electronic devices have various specifications, such as Type-C, Lightning, MicroUSB and other specifications. Electrical connectors of different specifications cannot match each other. Therefore, the connection accessories of electronic devices, such as USB flash drives, charging cables, etc., in order to be able to simultaneously adapt to electronic devices with multiple different specifications of sockets (i.e. female electrical connectors), usually need to be provided with plugs of corresponding specifications (i.e. male connectors). This will result in the connection accessories needing to be provided with multiple sockets at the same time to respectively install plugs of different specifications.

[0003] In order to allow each plug to have enough space to connect to the socket, existing connection accessories usually set each socket separately on a data cable. The presence of multiple data cables will increase the difficulty of users to organize and store them. Therefore, products that set multiple sockets in one piece have appeared on the market to save the trouble of data cables; however, since each socket needs to be equipped with a circuit board connected to the plug, setting up multiple sockets requires more or larger circuit boards to connect multiple plugs, which will inevitably increase the overall volume of the product and is not conducive to achieving product miniaturization. Therefore, how to meet the multi-socket adaptation function while taking into account the miniaturization design of the product is a problem that needs to be solved urgently. Summary of the invention

[0004] In view of this, the present invention provides a new adapter and a data cable to solve the above problems.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] See also Figures 1 to 12 A data cable 10 provided by an embodiment of the present invention includes a cable body 12 and a switching device 14 located at one end of the cable body 12. The cable body 12 is electrically connected to the switching device 14. The switching device 14 is used to be plugged into an interface of an electronic device to form an electrical connection between the data cable 10 and the electronic device.

[0033] It can be understood that the other end of the wire 12, that is, the end away from the adapter 14, can be plugged in and out with accessories such as a charging head or a mobile power supply, or can be directly fixed on a charging device such as a mobile power supply.

[0034] In other embodiments, the adapter 14 may also be an electronic device accessory such as a USB flash drive or a mobile power source for plugging and cooperating with an electronic device.

[0035] The adapter 14 includes a base 16 and a socket 18 . The line body 12 is electrically connected to the socket 18 . The socket 18 is rotatably mounted on the base 16 so that the socket 18 can rotate relative to the base 16 , thereby changing the relative position of the socket 18 to change the plugging direction of the adapter 14 .

[0036] The socket 18 may be rotatably mounted on the outside of the base 16, or an installation space 20 may be provided inside the base 16 for installing the socket 18. In this embodiment, the base 16 is provided with an installation space 20, which extends from an end of the base 16 away from the wire body 12 toward the wire body 12, and the socket 18 is rotatably mounted in the installation space 20 so that the socket 18 can rotate in the installation space 20.

[0037] The base 16 includes a first base body 22 and a second base body 24 that are arranged opposite to each other. The first base body 22 covers the second base body 24, and the first base body 22 and the second base body 24 cooperate to form an installation space 20, and the plug socket 18 is sandwiched between the first base body 22 and the second base body 24. By dividing the base 16 into two parts, the first base body 22 and the second base body 24, during the assembly process, the first base body 22 and the second base body 24 can be separated first, and the plug socket 18 can be installed to one of the base bodies, and then the two base bodies are fixed together to sandwich the plug socket 18 between the first base body 22 and the second base body 24, so as to facilitate the installation of the plug socket 18.

[0038] The first seat body 22 and the second seat body 24 are provided with wiring grooves inside. One end of the wiring grooves close to the socket 18 is connected to the installation space 20. The wire core 42 of the wire body 12 is electrically connected to the socket 18 located in the installation space 20 through the wiring grooves.

[0039] A rotating shaft 26 is installed on the base 16, and both ends of the rotating shaft 26 are respectively connected to the first base body 22 and the second base body 24. The socket 18 is penetrated by an axial hole 28 and is sleeved on the outer side of the rotating shaft 26 through the axial hole 28. The socket 18 is rotatably installed to the base 16 through the rotating shaft 26, so that the socket 18 can rotate around the rotating shaft 26 relative to the base 16.

[0040] Specifically, the shaft 26 is integrally formed with one of the first seat body 22 and the second seat body 24 and is interference fit with the other, so that the shaft 26 and the base 16 remain relatively fixed, and the socket 18 is movably sleeved on the outside of the shaft 26 through the shaft hole 28 .

[0041] In one embodiment, the socket 18 includes a first circuit board 30 and a plurality of plug-in parts 32 mounted on the first circuit board 30, the first circuit board 30 is electrically connected to the plurality of plug-in parts 32, and the shaft hole 28 passes through the first circuit board 30. By providing the socket 18 with a plurality of plug-in parts 32, the adapter 14 can be used in conjunction with a plurality of electronic devices or a plurality of different types of electronic devices. At the same time, the first circuit board 30 is rotatably matched with the rotating shaft 26, so that the first circuit board 30 can rotate relative to the base 16 around the rotating shaft 26, and drive the plug-in parts 32 connected thereto to rotate, thereby adjusting the relative positions of the plurality of plug-in parts 32, so as to adjust the corresponding plug-in parts 32 to a position convenient for connection with the electronic device.

[0042] It can be understood that among the multiple plug-in parts 32, all the plug-in parts 32 can be the same, so that the adapter 14 can be connected to multiple electronic devices at the same time, or all the plug-in parts 32 can be different, so that the adapter 14 can be connected to multiple different types of electronic devices, or some of the plug-in parts 32 can be the same and some can be different.

[0043] The specific number of the plug-in parts 32 is not limited, for example, two, three, etc. In the present embodiment, the number of the plug-in parts 32 is two, and the two plug-in parts 32 are respectively located at the two ends of the first circuit board 30, and the two plug-in parts 32 are of different types, namely, a type-c connector and a lightning connector, so that the data cable 10 can be adapted to electronic devices with a type-c interface and a lightning interface, thereby improving the adaptability of the adapter 14.

[0044] When the socket 18 is not needed or only one of the sockets 18 is needed, the socket 18 can be rotated so that one of the plug parts 32 extends from the end of the installation space 20 away from the wire body 12 to the outside of the base 16, and the other plug part 32 is stored in the installation space 20, so as to prevent the two plug parts 32 from extending to the outside of the base 16 at the same time, reduce the abruptness, and protect the unused plug parts 32. In addition, by rotating the socket 18, different sockets 18 can be extended to the outside of the base 16 to connect with different electronic devices.

[0045] Conductive structures 34 are respectively provided on opposite sides of the first circuit board 30, and the conductive structures 34 are electrically connected to the first circuit board 30, and the wire body 12 is connected to the conductive structures 34, so as to realize electrical connection with the plug-in portion 32. Specifically, the conductive structures 34 are respectively arranged on both sides of the first circuit board 30 in the thickness direction. By arranging the conductive structures 34 on both sides of the first circuit board 30, the installation space 20 on both sides of the first circuit board 30 can be fully utilized, and the problem that the conductive structures 34 are arranged on the same side of the first circuit board 30 and the size of the first circuit board 30 in the vertical thickness direction, that is, the horizontal direction becomes larger is avoided, which is conducive to reducing the circumferential size of the plug socket 18, thereby reducing the overall width size of the adapter 14, and helping to achieve miniaturization of the product, so that the adapter 14 can be embedded in other devices, for example, the adapter 14 is embedded in the card slot on the shell of a mobile power supply or a charger, and because the width size of the adapter 14 is reduced, the width of the card slot matched therewith is also reduced, thereby reducing the area proportion of the card slot on the shell surface and reducing the damage to the integrity of the shell appearance.

[0046] It can be understood that the conductive structure 34 can be a conductive layer on the first circuit board 30 , or a conductive metal member on the first circuit board 30 , etc.

[0047] In this embodiment, each conductive structure 34 includes a plurality of conductive members 36, and the conductive members 36 protrude from the surface of the first circuit board 30. The plurality of conductive members 36 located on the same side of the first circuit board 30 are arranged at intervals on the surface of the first circuit board 30. The two conductive structures 34 are respectively located on opposite sides of the first circuit board 30, and the arrangement direction of the two conductive members 34 is the thickness direction of the first circuit board 30. The plurality of conductive members 36 located on the same side of the first circuit board 30 are arranged at intervals in the direction perpendicular to the thickness, which can avoid the problem that the thickness of the socket 18 is too large due to the arrangement of the conductive members 36 along the thickness direction. The conductive members 36 are respectively arranged on the opposite sides of the first circuit board 30 to reduce the width dimension of the socket 18, so as to achieve the effect of taking into account the dimensions in both the thickness and width directions. Moreover, the structure of the interval arrangement forms an assembly space between two adjacent conductive members 36, which is conducive to the installation of electrical components electrically connected to the conductive members 36 without occupying the space in the thickness direction.

[0048] In this embodiment, the conductive member 36 is a conductive ring, that is, the conductive member 36 is annular, and multiple conductive rings located on the same side of the first circuit board 30 are arranged in concentric circles, that is, the central axes of the multiple conductive rings on the same side of the first circuit board 30 are collinear, so that the arrangement is more compact, so as to reduce the circumferential size of the socket 18. It should be understood that the annular conductive member 36 can be an open ring, so that the conductive member 36 can be produced by a mature metal bending process, reducing the production cost; or it can be a closed ring to provide a complete and continuous electrical connection surface, thereby improving the stability of the electrical connection.

[0049] The central axis of the conductive ring is collinear with the rotation axis of the socket 18, so that when the socket 18 rotates relative to the base 16, the electrical components on the base 16 (or components fixed relative to the base 16) that need to be electrically connected to the conductive ring always maintain close contact, preventing the socket 18 from disconnecting the electrical connection with the conductive ring during the 360° rotation, thereby improving the stability of the electrical connection. Specifically, the central axes of all the conductive rings on the first circuit board 30 are collinear with the central axis of the rotating shaft 26, and the rotation axis of the socket 18 is the central axis of the rotating shaft 26.

[0050] The plurality of conductive members 36 located on opposite sides of the first circuit board 30 are arranged alternately at intervals. Specifically, the conductive members 36 take conductive rings as an example, and the alternating arrangement means that, along the radial direction of the conductive rings, a conductive ring on one side of the first circuit board 30 is located between two adjacent conductive rings on the other side of the first circuit board, and the number of conductive rings located on different sides of the first circuit board 30 is different. Three conductive rings are provided on one side of the first circuit board 30, and two conductive rings are provided on the other opposite side. Along the radial direction of the conductive rings, the plurality of conductive rings located on opposite sides of the first circuit board 30 are arranged alternately at intervals. For example, the first circuit board 30 has an opposite upper surface and a lower surface, two conductive rings are provided on the upper surface and an assembly space is formed between the two, and another conductive ring is provided on the lower surface and is located below the above-mentioned assembly space, and so on. The design of arranging multiple conductive rings on opposite sides of the first circuit board 30 alternately at intervals allows all the conductive rings to be tightly arranged on the first circuit board 30 while forming an assembly space between two adjacent conductive rings on the same side of the first circuit board 30, thereby making the internal structure of the adapter 14 more compact. Compared with arranging all the conductive rings on the same side, the circumferential size of the first circuit board 30 can be significantly reduced, thereby reducing the circumferential size of the socket 18 and even the adapter 14, and the connection parts of the conductive rings and the first circuit board 30 can be staggered, thereby avoiding interference of the conductive ring on one side of the first circuit board 30 with the conductive ring on the other side when connecting to the first circuit board 30.

[0051] The conductive ring is provided with a connection portion 37 for plugging and mating with the first circuit board 30, and the first circuit board 30 is correspondingly provided with a connection hole 39, and the connection portion 37 is inserted into the connection hole 39 to realize the electrical connection between the conductive ring and the first circuit board 30. The multiple conductive rings on different sides are alternately arranged at intervals, so that the connection portions 37 on different conductive rings can be staggered to avoid mutual interference. Each conductive ring is preferably provided with two connection portions 37, and the two connection portions 37 are located in the diameter direction of the conductive ring, so that the two most distant parts of the conductive ring are fixed on the first circuit board 30, so as to improve the stability of the connection between the conductive ring and the first circuit board 30.

[0052] The connection parts 37 of the multiple conductive rings located on one side of the first circuit board 30 are arranged at intervals along the first radial direction of the conductive rings, and the connection parts 37 of the multiple conductive rings located on the other side of the first circuit board 30 are arranged at intervals along the second radial direction of the conductive rings, and the first radial direction and the second radial direction are perpendicular to each other. Specifically, three conductive rings are provided on one side of the first circuit board 30, and the connection parts 37 of the three conductive rings are arranged along the first radial direction, which is, for example, the width direction of the first circuit board 30; two conductive rings are provided on the other side of the first circuit board 30, and the connection parts 37 of the two conductive rings are arranged along the second radial direction, which is, for example, the length direction of the first circuit board 30; the connection parts 37 of the two conductive rings located on one side of the first circuit board 30 are respectively inserted between two adjacent conductive rings on the other side, so that the multiple conductive rings located on different sides of the first circuit board 30 are alternately arranged at intervals along the radial direction.

[0053] The height of the connecting portion 37 is 0.5 mm to 1.5 mm, and the height of the connecting portion 37 is greater than the thickness of the first circuit board 30, so as to ensure the stability of the connection between the connecting portion 37 and the first circuit board 30, that is, to ensure the stability of the electrical connection between the conductive ring and the first circuit board 30. Preferably, the height of the connecting portion 37 is 1 mm, and the thickness of the first circuit board 30 is 0.8 mm. In order to pursue a smaller size design, in one embodiment, the height of the connecting portion 37 can be set to 0.5 mm, and the thickness of the first circuit board 30 is 0.4 mm.

[0054] In one embodiment, the first circuit board 30 is rectangular, the length of the first circuit board 30 is 18 mm to 28 mm, and the width of the first circuit board 30 is 5 mm to 15 mm. By controlling the length and width of the first circuit board 30 within this range, it is possible to avoid the circumferential dimension of the first circuit board 30 being too large, which results in an increase in the overall circumferential dimension of the product, and to avoid the circumferential dimension of the first circuit board 30 being too small, which affects the installation of the conductive ring. Preferably, the length of the first circuit board 30 is 23 mm, and the width of the first circuit board 30 is 10 mm. It should be understood that when the width of the first circuit board 30 is set to 5 mm, the number, thickness and outer diameter of the conductive ring can be reduced to match the width design.

[0055] It should be noted that the first circuit board 30 is rectangular, which includes a regular rectangle and an irregular rectangle with smaller recesses or protrusions on the periphery of the first circuit board 30, as long as the circumferential contour of the first circuit board 30 is roughly rectangular.

[0056] It is understandable that, since the width of the first circuit board 30 is smaller than its length, protrusions may be provided on both sides of the width of the first circuit board 30 to increase the size of the first circuit board 30 at that location to facilitate installation of the conductive ring.

[0057] A plurality of soldering portions 41 for connecting with the plug-in portion 32 are respectively provided at both ends of the first circuit board 30, and the plurality of soldering portions 41 located at the same end of the first circuit board 30 are arranged at intervals. The soldering portions 41 are metal contacts on the first circuit board 30, and are used to solder with the metal pins of the plug-in portion 32, so as to fix the plug-in portion 32 on the first circuit board 30 and form an electrical connection. Specifically, each soldering portion 41 includes two solder pads located on opposite sides of the first circuit board 30.

[0058] The specific number of soldering portions 41 connected to each plug-in portion 32 is not limited. In the present application, the number of soldering portions 41 located at the same end of the first circuit board 30 is 6 to 10. Specifically, the number of soldering portions 41 located at the same end of the first circuit board 30 is 8, that is, 8 solder pads are respectively provided on the two side surfaces at the same end of the first circuit board 30.

[0059] The spacing between the two soldering portions 41 located at the same end of the first circuit board 30 and the farthest apart is 5 mm to 9 mm, so as to prevent the problem that the size of each soldering portion 41 is too small and causes inconvenience in connecting with the plug-in portion 32. Specifically, the spacing between the two soldering portions 41 located at the same end of the first circuit board 30 and the farthest apart is 6 mm, or the width of each soldering pad is 0.6 mm, and the spacing between two adjacent soldering pads (or soldering portions 41) is 0.3 mm, so as to ensure sufficient soldering space while taking into account the small volume design.

[0060] The socket 18 also includes a second circuit board 38 spaced apart on opposite sides of the first circuit board 30, the conductive member 36 is located between the first circuit board 30 and the second circuit board 38, the wire body 12 is electrically connected to the second circuit board 38, and the second circuit board 38 is electrically connected to the conductive member 36 on the first circuit board 30, that is, the wire body 12 is electrically connected to the first circuit board 30 through the second circuit board 38, and the shaft hole 28 passes through the second circuit board 38. Providing the second circuit board 38 on opposite sides of the first circuit board 30 in the thickness direction helps to reduce the width of the socket 18.

[0061] Specifically, a certain distance is maintained between the second circuit board 38 and the conductive member 36 to prevent the second circuit board 38 from affecting the rotation of the socket 18 .

[0062] The second circuit board 38 is provided with a pin 40, which extends toward the first circuit board 30 and can contact the conductive member 36. In this embodiment, the conductive member 36 is a conductive ring, and the pin 40 contacts the circumferential inner wall or outer wall of the conductive ring. Preferably, the height of the pin 40 is less than the height of the conductive member 36 protruding from the first circuit board 30, so as to avoid the end of the pin 40 contacting the surface of the first circuit board 30 and increasing the resistance to rotation. Since the conductive member 36 is annular, the pin 40 is always connected to the conductive member 36 during the rotation of the socket 18, so as to avoid the problem that the first circuit board 30 and the second circuit board 38 are disconnected from the electrical connection during the rotation of the socket 18, thereby affecting the use.

[0063] Preferably, the pin 40 is a metal spring sheet with a contact point protruding from the metal spring sheet. The metal spring sheet has a certain elasticity and presses the contact point tightly onto the conductive member 36 .

[0064] The contact may be in contact with the radial outer wall of the conductive ring or the radial inner wall of the conductive ring. In the present application, the contact extends toward the radial outer wall of the corresponding conductive ring (i.e., the conductive ring in contact with the contact) and contacts the radial outer wall of the conductive ring.

[0065] Preferably, the pin 40 is arc-shaped to enhance the overall strength of the pin 40. The inner surface of the pin 40 close to the corresponding conductive ring and the outer surface away from the corresponding conductive ring are both arc surfaces, and the inner surface is concave and the outer surface is convex. The contact is arranged on the concave surface to match the circular conductive ring, improve the tightness of the connection, and thus improve the stability of the electrical connection between the pin 40 and the conductive ring.

[0066] The height of the conductive member 36 protruding from the surface of the first circuit board 30 is preferably in the range of 2 mm to 4 mm, and the height of the pin 40 from the second circuit board 38 to the first circuit board 30 is 1 mm to 3 mm, ensuring that there is sufficient electrical connection area between the pin 40 and the conductive ring to ensure the stability of the electrical connection. Preferably, the height of the conductive member 36 protruding from the surface of the first circuit board 30 is 2 mm, and the height of the pin 40 is 1.8 mm.

[0067] The second circuit board 38 is rectangular, the length of the second circuit board 38 is 11 mm to 21 mm, and the width of the second circuit board 38 is 5 mm to 15 mm. Controlling the length and width of the second circuit board 38 within this range can prevent the circumferential dimension of the second circuit board 38 from being too large or too small, thereby affecting the installation of the pins 40. Preferably, the length of the second circuit board 38 is 16.5 mm, and the width of the second circuit board 38 is 10 mm.

[0068] It should be noted that the second circuit board 38 is rectangular, which includes a regular rectangle and an irregular rectangle with smaller recesses or protrusions on the periphery of the second circuit board 38, as long as the circumferential contour of the second circuit board 38 is roughly rectangular.

[0069] In other embodiments, the conductive member may also be composed of a plurality of conductive parts, which are arranged at intervals along the rotation direction of the socket. After the socket rotates a corresponding angle, the conductive parts can contact the corresponding pins to form an electrical connection. By arranging the conductive parts at intervals, it can be achieved that after the socket rotates a preset angle relative to the base, the conductive parts contact and electrically connect with the preset electrical components, or are displaced from the preset electrical components to disconnect the electrical connection.

[0082] It should be noted that the first circuit board 30 and the conductive member 36 are located inside the shell 84 , which may mean that the first circuit board 30 and the conductive member 36 are entirely located inside the shell 84 , or may be partially located inside the shell 84 .

[0083] The housing 84 is provided with a avoidance hole 86 corresponding to the conductive structure, and the conductive structure is at least partially located in the avoidance hole 86. Specifically, the conductive structure is, for example, a conductive member 36, and the housing 84 is provided with a avoidance hole 86 corresponding to the conductive member 36. The conductive member 36 is located in the avoidance hole 86 and is spaced from the inner wall of the avoidance hole 86. The second circuit board 38 is located outside the housing 84 so that the pins 40 on the second circuit board 38 extend into the avoidance hole 86 and contact the conductive member 36. The avoidance hole 86 of the housing 84 is designed so that the socket 18 can be unobstructed during the rotation process, so that the conductive member 36 always maintains an electrical connection with the pins 40, and the thickness of the socket 18 is reduced.

[0085] A positioning structure 92 is provided between the housing 84 and the base 16, and the positioning structure 92 can prevent the socket 18 from rotating relative to the base 16, thereby positioning the socket 18 at a corresponding position to enhance the stability of the socket 18 during use. Specifically, a positioning structure 92 is provided between the first housing 88 and the first seat body 22 and between the second housing 90 and the second seat body 24 to enhance the positioning effect.

The positioning protrusion 94 is arranged on the base 16, and the positioning hole 96 is correspondingly arranged on the shell 84. When the positioning protrusion 94 is inserted into the positioning hole 96, the positioning protrusion 94 can prevent the socket 18 from rotating, so as to position the socket 18 at this position.
