[0012] As an optimal technical solution for a rotatable plug connector, the circuit board storage cavity is connected to the external environment through an interface avoidance hole, and the interface body passes through the interface avoidance hole; when the interface module swings around the axis of the rotating shaft, the interface module is stopped at the interface body and the side wall of the interface avoidance hole.

[0030] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1-Figure 3 As shown, this embodiment provides a circuit board connection structure, including a transfer circuit board 200 and an interface circuit board 140; the upper board surface of the transfer circuit board 200 is provided with a through hole 201 and an arc-shaped transfer pad coaxial with the through hole 201, the arc-shaped transfer pad is fixed with a conductive PIN needle, and the conductive PIN needle is convexly provided with a protrusion; the lower board surface of the interface circuit board 140 is convexly provided with a rotating shaft 150 and an arc-shaped interface pad coaxial with the rotating shaft 150; the rotating shaft 150 is connected to the through hole 201, and the interface circuit board 140 can swing relative to the transfer circuit board 200 around the axis of the rotating shaft 150, and the protrusion is pressed against the arc-shaped interface pad and can slide relative to the arc-shaped interface pad.

[0035] The circuit board connection structure uses the design of the rotating shaft 150 passing through the through hole 201 to ensure that the interface circuit board 140 can smoothly swing around the axis of the rotating shaft 150 relative to the adapter circuit board 200; the setting of the arc-shaped adapter pad coaxial with the through hole 201 and the arc-shaped interface pad coaxial with the rotating shaft 150 ensures the connection ability between the two, so that the arc-shaped adapter pad and the corresponding arc-shaped interface pad can be smoothly contacted; by setting a conductive PIN needle, the connection method of the arc-shaped adapter pad and the corresponding arc-shaped interface pad is changed, thereby ensuring that the two pads are always in contact. The above setting improves the connection effect between the arc-shaped adapter pad and the arc-shaped interface pad, and ensures that the electrical connection between the interface body 170 and the connecting cable 300 can be successfully completed. The above structure reduces the risk of damage and deformation of the conductive PIN pin by designing that the protrusion presses against the arc-shaped interface pad and can slide relative to the arc-shaped interface pad, improves the electrical connection effect between the arc-shaped transfer pad and the arc-shaped interface pad, ensures the smooth operation of the structure, and extends its service life.

[0036] In this embodiment, the conductive PIN pin also includes two connecting parts, which are respectively located on both sides of the protruding part, and the two connecting parts are fixed to the arc-shaped transfer pad. The above structural improvement of the conductive PIN pin ensures that the arc-shaped transfer pad and the arc-shaped interface pad can be electrically connected through the conductive PIN pin. The selection of the specific structure of the conductive PIN pin and the design of the connection relationship improve the stress of the conductive PIN pin during the reciprocating swing of the arc-shaped interface pad, thereby extending the service life of the rotatable plug connector.

[0037] Preferably, the conductive PIN is formed by bending a metal sheet, the two connecting parts are formed by bending the two ends of the metal sheet downward, and the protruding part is formed by bending the middle part of the metal sheet upward. The method of making the conductive PIN by bending the metal sheet is simple and efficient, which greatly reduces the manufacturing difficulty and production cost of the conductive PIN and improves the production efficiency.

[0038] like Figure 4 As shown, the conductive PIN pin in the figure is defined as the second PIN pin 221, the arc-shaped transfer pad in the figure is defined as the second transfer pad 220, the two connecting parts of the second PIN pin 221 are both defined as the second PIN pin connecting parts 2211, and the protruding part of the second PIN pin 221 is defined as the second PIN pin protruding part 2212. Specifically, the two second PIN pin connecting parts 2211 are both welded to the second transfer pad 220.

[0039] Continue to refer Figure 1-Figure 3 This embodiment provides a rotatable plug connector, including a connecting cable 300, an interface module 100 and the above-mentioned circuit board connection structure; the adapter circuit board 200 is connected to the connecting cable 300; the interface module 100 includes an interface circuit board 140 and an interface body 170 connected to the interface circuit board 140, and the interface body 170 is used to connect an external device.

[0040] The rotatable plug connector utilizes the design of the interface module 100 swinging around the axis of the rotating shaft 150 relative to the adapter circuit board 200, so as to adjust the relative position of the interface body 170 and the connecting cable 300, thereby ensuring the smooth connection between the connecting cable 300 and the interface body 170. The above structural improvement can meet the setting requirements of the rotatable plug connector when there are special space requirements. By adjusting the orientation of the interface body 170, the outlet direction of the connecting cable 300 is changed, so as to adapt to the arrangement of the connecting cable 300 in different spaces, and reduce the swing requirements for the connecting cable 300; the above design reduces the bending and twisting of the rotatable plug connector when it is installed in the external environment, thereby reducing the risk of damage to the plug connector and extending the service life.

[0041] Preferably, the upper surface of the adapter circuit board 200 is provided with at least one arc-shaped adapter pad coaxial with the through hole 201, and the lower surface of the interface circuit board 140 is provided with an arc-shaped interface pad coaxial with the rotating axis 150. The number of the arc-shaped interface pads and the arc-shaped adapter pads are the same and they are opposite to each other, and each arc-shaped adapter pad is in contact with a corresponding arc-shaped interface pad through a conductive PIN needle.

[0042] Further, there are three arc-shaped transfer pads, namely, a first transfer pad 210, a second transfer pad 220, and a third transfer pad 230, which are arranged sequentially from the outside to the inside; there are three arc-shaped interface pads, namely, a first interface pad 110, a second interface pad 120, and a third interface pad 130, which are arranged sequentially from the outside to the inside; the first transfer pad 210 contacts the first interface pad 110 through the first PIN needle 211, the second transfer pad 220 contacts the second interface pad 120 through the second PIN needle 221, and the third transfer pad 230 contacts the third interface pad 130 through the third PIN needle 231. Specifically, there is one third PIN needle 231, and two are provided for each of the first PIN needle 211 and the second PIN needle 221. When the interface circuit board 140 swings within a predetermined range relative to the adapter circuit board 200, the two first PIN pins 211 are always connected to the first interface pad 110 at the same time, the two second PIN pins 221 are always connected to the second interface pad 120 at the same time, and the third PIN pin 231 is always connected to the third interface pad 130.

[0043] The above design ensures that each arc-shaped transfer pad can be connected to the corresponding arc-shaped interface pad, thereby further ensuring the electrical connection effect between the interface body 170 and the connecting cable 300. The layout design of multiple arc-shaped pads arranged in sequence from outside to inside reduces the space occupied by the transfer circuit board 200 and the interface circuit board 140, and reduces the production cost of the transfer circuit board 200 and the interface circuit board 140.

[0044] In this embodiment, the connecting cable 300 includes a first electrical connecting wire 311, a second electrical connecting wire 321, a third electrical connecting wire and a cable protective cover 340. The outer layer of the first electrical connecting wire 311 is sleeved with a first insulating cover 312, the outer layer of the second electrical connecting wire 321 is sleeved with a second insulating cover 322, and the outer layer of the third electrical connecting wire is sleeved with a third insulating cover 332. The cable protective cover 340 is sleeved on the outer layers of the first insulating cover 312, the second insulating cover 322 and the third insulating cover 332.

[0045] Preferably, the adapter circuit board 200 is further provided with a first connection pad 240, a second connection pad 250 and a third connection pad. The first adapter pad 210 is electrically connected to the first connection pad 240, the first electrical connection line 311 is welded to the first connection pad 240, the second adapter pad 220 is electrically connected to the second connection pad 250, the second electrical connection line 321 is welded to the second connection pad 250, the third adapter pad 230 is electrically connected to the third connection pad, and the third electrical connection line is welded to the third connection pad. The first interface pad 110, the second interface pad 120 and the third interface pad 130 are electrically connected to the interface body 170 respectively. Specifically, the first electrical connection line 311 is a CC (Configuration Channel) line, the second electrical connection line 321 is a Vbus (Voltage Bus) line, and the third electrical connection line is a GND (Ground) line.

[0046] In this embodiment, a protective housing is also included, and the protective housing is provided with a cable storage cavity and a circuit board storage cavity, part of the connecting cable 300 extends into the cable storage cavity, the adapter circuit board 200 and part of the interface module 100 are placed in the circuit board storage cavity, and the part of the interface module 100 with the interface body 170 extends out of the protective housing. The protective housing not only protects the adapter circuit board 200 and the interface module 100, but also provides storage space for the adapter circuit board 200 and the interface module 100, reduces the risk of accidental separation of the adapter circuit board 200 and the interface module 100, ensures the smooth operation of the rotatable plug connector, and reduces the frequency of maintenance.

[0047] Furthermore, the circuit board storage cavity is connected to the external environment through the interface avoidance hole, and the interface body 170 passes through the interface avoidance hole; when the interface module 100 swings around the axis of the rotating shaft 150, the interface module 100 stops at the interface body 170 and the side wall of the interface avoidance hole. The design of limiting the swing range through rigid contact effectively simplifies the structure of the rotatable plug connector, and also avoids the situation where the interface circuit board 140 exceeds the range due to accidents. The above design is simple and reliable, with low production cost and high working stability.

[0048] Furthermore, the interface avoidance hole is provided with two side walls, and the two side walls of the interface avoidance hole are opposite to each other; the interface module 100 can swing between the first extreme position and the second extreme position, when the interface module 100 is in the first extreme position, the interface module 100 abuts against one side wall of the interface avoidance hole, and when the interface module 100 is in the second extreme position, the interface module 100 abuts against the other side wall of the interface avoidance hole. The above design is simple and reliable, accurately defines the two extreme positions of the interface module 100 during the swinging process, and thereby defines the swinging trajectory of the interface module 100, ensuring the ability to adjust the relative angle between the orientation of the interface body 170 and the outlet direction of the connecting cable 300.

[0049] Specifically, when the interface module 100 swings from the first extreme position to the second extreme position, the interface module 100 rotates 45°.

[0050] Preferably, the protective housing is provided with two swing avoidance grooves, each of which is connected to a side wall of the interface avoidance hole. When the interface module 100 is against the side wall of the interface avoidance hole, the side surface of the interface body 170 fits with the groove wall of the swing avoidance groove. Specifically, the groove wall of the swing avoidance groove is an arc surface. The above design provides space for the interface body 170 to avoid the external device, thereby reducing the interference between the interface body 170 and the protective housing when rotating.

[0051] Preferably, the protective housing is provided with a magnetic member receiving chamber, and a third magnetic member 600 is provided in the magnetic member receiving chamber, and the third magnetic member 600 can be magnetically attracted to an external device having magnetic force. The third magnetic member 600 can magnetically attract an external device when the rotatable plug connector is working, thereby realizing the locking action of the socket connector, which is convenient to use, simple in structure and low in production cost.

[0052] Furthermore, the protective shell includes a lower protective shell 400 and an upper protective shell 500 which are spliced ​​together. The lower protective shell 400 is provided with a lower cable storage groove 410, a lower circuit board storage groove 420 and a lower magnetic suction component storage groove 430. The upper protective shell 500 is provided with an upper cable storage groove, an upper circuit board storage groove and an upper magnetic suction component storage groove. The lower cable storage groove 410 and the upper cable storage groove form a cable storage cavity, the lower circuit board storage groove 420 and the upper circuit board storage groove form a circuit board storage cavity, and the lower magnetic suction component storage groove 430 and the upper magnetic suction component storage groove form a magnetic suction component storage cavity.

[0053] Specifically, the lower cable storage groove 410 is connected to the side of the lower protective shell 400 through the lower cable avoidance opening 401, the upper cable storage groove is connected to the side of the upper protective shell 500 through the upper cable avoidance opening 501, the lower circuit board storage groove 420 is connected to the side of the lower protective shell 400 through the lower interface avoidance opening 402, the upper circuit board storage groove is connected to the side of the upper protective shell 500 through the upper interface avoidance opening 502, the two lower swing avoidance openings 403 are respectively connected to the side walls of the two lower interface avoidance openings 402, and the two upper swing avoidance openings 503 are respectively connected to the side walls of the two upper interface avoidance openings 502. The lower cable avoidance opening 401 and the upper cable avoidance opening 501 are spliced ​​to form a cable avoidance hole, and the connecting cable 300 is inserted into the cable storage cavity through the cable avoidance hole. The lower interface avoidance opening 402 and the upper interface avoidance opening 502 are spliced ​​to form an interface avoidance hole, and the upper swing avoidance opening 503 and the lower swing avoidance opening 403 are spliced ​​to form a swing avoidance groove. The split design of the protective shell greatly reduces the difficulty of the protective shell production, reduces the processing cost, and improves the manufacturing efficiency.

[0054] In this embodiment, a first magnetic member 190 is fixedly connected to the interface circuit board 140, and a second magnetic member 260 is fixedly connected to the adapter circuit board 200; a recovery position is provided between the first extreme position and the second extreme position, and when the interface module 100 is in the recovery position, the distance between the first magnetic member 190 and the second magnetic member 260 is the smallest, and the first magnetic member 190 can drive the interface module 100 to swing toward the recovery position. The above design enables the interface module 100 to automatically move to the recovery position without being affected by the external environment, thereby completing the automatic return action of the interface module 100. The above design is simple and reliable, reduces the difficulty for the operator to adjust the position of the interface module 100, simplifies the process of connecting the interface body 170 with external equipment, and improves the user experience of the operator.

[0055] Specifically, a protective frame 180 is embedded in the upper surface of the interface circuit board 140 , and the first magnetic member 190 is snap-connected to the protective frame 180 .

[0056] In other implementations of this embodiment, the two third magnetic members 600 repel the first magnetic member 190, and no magnetic member is provided on the adapter circuit board 200. When the two third magnetic members 600 push the first magnetic member 190 to stop at a force-balanced position, the interface module 100 is located in the restored position. The above design completes the positioning operation of the first magnetic member 190 by balancing the repulsive force of the two third magnetic members 600 on the first magnetic member 190, thereby realizing the automatic return action of the interface module 100. The above design is simple and reliable, has low production cost, occupies less space, and can accurately and stably complete the operation of adjusting the position of the interface module 100.
