Description

Technical Field

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

[0002] Connectors are common functional components in electronic devices such as computers. They enable the interconnection of circuit boards within an electronic device or allow the device to connect to other peripheral devices. To avoid assembly problems caused by angular limitations between two circuit boards, a connector consists of two rotatable connecting parts, each connected to a circuit board.

[0003] However, since the connecting part has multiple terminals, when the two connecting parts rotate relative to each other, the terminal of one connecting part needs to keep in contact with the corresponding terminal of the other connecting part. If most of the terminal is exposed to the outside, a short circuit may easily occur when the distance between the electrodes is small, which poses a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a connector and electronic device that can reduce the exposed area of ​​terminals and reduce the risk of short circuits.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A connector, comprising:

[0007] The first connector includes a first connector seat and a first terminal disposed within the first connector seat. The first connector seat is provided with a plurality of connecting grooves at intervals. The first terminal includes a first connecting end and a first fixing end. The radial end face of the first connecting end abuts against the inner wall of the connecting groove, and the outer peripheral surface of the first connecting end is located within the connecting groove and exposed through the connecting groove.

[0008] The second connector includes a second connector seat and a second terminal disposed within the second connector seat and corresponding to the first terminal. The second connector seat is rotatably connected to the first connector seat. The second terminal includes a second connecting end and a second fixed end. The second connecting end slides against the outer peripheral surface of the first connecting end of the corresponding first terminal through the connecting groove.

[0009] As an optional solution for the aforementioned connector, the second connecting end elastically abuts against the first connecting end.

[0010] As an alternative to the above connector, the outer surface of the first connecting end includes an arc-shaped segment, and when the second connecting seat rotates with the first connecting seat, the second connecting end always abuts against the arc-shaped segment.

[0011] As an alternative to the above connector, the arc segment is a circular arc, and the center of the circular arc is located on the rotation axis between the second connector and the first connector.

[0012] As an alternative to the above connector, at least one of the first connector and the second connector is provided with a limiting block, which is configured to limit the minimum included angle between the first connector and the second connector.

[0013] As an optional embodiment of the above connector, the first connector includes a first rotating part, the second connector includes two second rotating parts spaced apart, the first rotating part is rotatably disposed between the two second rotating parts, and a plurality of the connecting grooves are disposed on the first rotating part and spaced apart along the rotation axis of the second connector and the first connector.

[0014] As an alternative to the above connector, a rotating shaft is provided on the inner side of each of the two second rotating parts, and a rotating groove is provided at both ends of the first rotating part. The rotating shaft is inserted into the corresponding rotating groove so that the second connecting seat is rotatably connected to the first connecting seat.

[0015] As an alternative to the aforementioned connector, a portion of the first connecting end of the first terminal is embedded in the first rotating part.

[0016] As an optional embodiment of the aforementioned connector, the first connector is provided with a plurality of limiting grooves spaced circumferentially along the rotation axis of the second connector and the first connector, and the second connector is provided with limiting protrusions, which can engage with the plurality of limiting grooves to fix the first connector and the second connector at different angles; or

[0017] The second connector is provided with a plurality of limiting grooves spaced circumferentially along the rotation axis of the second connector and the first connector. The first connector is provided with limiting protrusions, which can be engaged in the plurality of limiting grooves to fix the first connector and the second connector at different angles.

[0018] An electronic device comprising the connector described above.

[0019] The beneficial effects of this utility model are:

[0020] This invention provides a connector and an electronic device. The connector has a first connector for fixing a first circuit board and a second connector for fixing a second circuit board. The first and second circuit boards can be adjusted to a suitable angle position by rotating the first and second connectors.

[0021] Since the first connector is provided with multiple connecting grooves at intervals, and the radial end face of the first connector abuts against the inner wall of the connecting groove, only the outer peripheral surface of the first connector is exposed through the connecting groove, which greatly reduces the exposed area of ​​the first terminal and reduces the risk of short circuit.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment provides an electronic device, such as Figure 1As shown, the electronic device includes a first circuit board 100 and a second circuit board 200. In order to connect the first circuit board 100 and the second circuit board 200, the electronic device also includes a connector, which is fixedly connected to the first circuit board 100 and the second circuit board 200 respectively, so as to realize the connection and conduction between the first circuit board 100 and the second circuit board 200.

[0038] Understandably, the positions of the first circuit board 100 and the second circuit board 200 need to be designed during the development of electronic devices. To avoid the difference in angle between the first circuit board 100 and the second circuit board 200 affecting the structural design, a connector is used to rotatably connect the first circuit board 100 and the second circuit board 200.

[0039] like Figures 1-4 As shown, to achieve the above objective, the connector includes a first connector 1 and a second connector 2. The first connector 1 includes a first connector 11 and a first terminal 12 disposed within the first connector 11. The second connector 2 includes a second connector 21 and a second terminal 22 disposed within the second connector 21 and corresponding to the first terminal 12. The first terminal 12 includes a first connecting end 121 and a first fixed end 122. The second connector 21 is rotatably connected to the first connector 11. The second terminal 22 includes a second connecting end 221 and a second fixed end 222. The second connecting end 221 slides against the outer peripheral surface of the first connecting end 121 of the corresponding first terminal 12.

[0040] The connector's first connector 1 is used to fix the first circuit board 100, and the second connector 2 is used to fix the second circuit board 200. Specifically, the first fixing end 122 extends out of the first connecting seat 11 and is fixedly connected to the first circuit board 100, and the second fixing end 222 extends out of the second connecting seat 21 and is fixedly connected to the second circuit board 200. Rotation of the first connector 1 and the second connector 2 allows the first circuit board 100 and the second circuit board 200 to be adjusted to a suitable angle. Furthermore, the first fixing segment of the first terminal 12 is fixedly connected to the first circuit board 100, and the second fixing end 222 of the second terminal 22 is fixedly connected to the second circuit board 200. By sliding the second connecting end 221 of the second terminal 22 against the first connecting end 121 of the first terminal 12, the first circuit board 100 and the second circuit board 200 can maintain a communication connection during rotation and at any angle.

[0041] In this embodiment, the first fixed end 122 is welded and fixed to the first circuit board 100, and the second fixed end 222 is welded and fixed to the second circuit board 200.

[0042] In this embodiment, the first connecting seat 11 is provided with a plurality of connecting grooves 111 at intervals. The radial end face of the first connecting end 121 abuts against the inner wall of the connecting groove 111. The outer peripheral surface of the first connecting end 121 is located inside the connecting groove 111 and exposed through the connecting groove 111. The second connecting end 221 slides against the outer peripheral surface of the first connecting end 121 of the corresponding first terminal 12 through the connecting groove 111.

[0043] Since the radial end face of the first connecting end 121 abuts against the inner wall of the connecting groove 111, only the outer peripheral surface of the first connecting end 121 of the first terminal 12 is exposed through the connecting groove 111, which greatly reduces the exposed area of ​​the first terminal 12 and reduces the risk of short circuit.

[0044] In some embodiments, the first connector 1 includes a plurality of first terminals 12, and the second connector 2 includes a plurality of second terminals 22. The first connecting ends 121 of the plurality of first terminals 12 are respectively disposed in the corresponding connecting grooves 111 to ensure that the plurality of first terminals 12 do not contact each other. The second connecting ends 221 of the plurality of second terminals 22 need to extend into the corresponding connecting grooves 111 to abut against the first connector 1 of the corresponding first terminal 12. This is equivalent to the first connector 11 separating the terminal pairs formed by adjacent first terminals 12 and second terminals 22 through the connecting grooves 111, ensuring that the first terminals 12 and second terminals 22 can only abut against each other. Therefore, the connector can reduce the gap between adjacent terminals and reduce the size of the connector.

[0045] In this embodiment, the second connecting end 221 elastically abuts against the first connecting end 121. When the first connecting end 121 and the second connecting end 221 are worn, the second connecting end 221 can still abut against the first connecting end 221 under the action of elastic force, thus ensuring the reliability of the connection between the first connecting end 121 and the second connecting end 221.

[0046] Specifically, the second connecting end 221 and the second fixed end 222 are set at an angle, and when the second connecting end 221 abuts against the first connecting end 121, the angle between the second connecting end 221 and the second fixed end 222 changes, and the elastic force between the second connecting end 221 and the first connecting end 121 is provided by the elastic deformation of the second terminal 22 itself.

[0047] Since the first connecting end 121 and the second connecting end 221 need to be kept in contact when the first connecting seat 11 and the second connecting seat 21 rotate, the outer surface of the first connecting end 121 includes an arc-shaped segment 123. When the second connecting seat 21 and the first connecting seat 11 rotate, the second connecting end 221 is always in contact with the arc-shaped segment 123.

[0048] Furthermore, the arc segment 123 is a circular arc, and the center of the arc is located on the rotation axis 213 line between the second connecting seat 21 and the first connecting seat 11. This structure ensures that the distance between the second connecting end 221 and the rotation axis 213 line remains constant regardless of the rotation angle between the second connecting seat 21 and the first connecting seat 11. Therefore, the magnitude of the elastic force of the second connecting end 221 on the first connecting end 121 remains constant, resulting in more uniform wear between the first connecting end 121 and the second connecting end 221, extending service life, and maintaining constant damping during rotation, thus optimizing the feel.

[0049] In this embodiment, the first circuit board 100 and the second circuit board 200 switch between being on the same plane and being stacked. That is, the included angle between the first circuit board 100 and the second circuit board 200 is in the range of 0° to 180°, and the included angle between the first circuit board 100 and the second circuit board 200 can be adjusted within the above range.

[0050] As the angle between the first circuit board 100 and the second circuit board 200 gradually decreases, the interference between the electronic components of the first circuit board 100 and the electronic components of the second circuit board 200 needs to be considered to prevent the electronic components from being damaged. For example... Figure 2 , Figure 5 and Figure 6 As shown, to solve this problem, at least one of the first connector 11 and the second connector 21 is provided with a limiting block 211. The limiting block 211 is configured to limit the minimum included angle between the first connector 11 and the second connector 21, so as to ensure that the electronic components will not collide and squeeze each other or collide and squeeze with the first circuit board 100 or the second circuit board 200.

[0051] In this embodiment, both the first connecting seat 11 and the second connecting seat 21 are provided with limiting blocks 211. When the limiting block 211 of the first connecting seat 11 abuts against the limiting block 211 of the second connecting seat 21, the first circuit board 100 and the second circuit board 200 are stacked and parallel to each other.

[0052] like Figure 2 , Figure 5 and Figure 6 As shown, in order to ensure a stable connection and smooth rotation between the first connecting seat 11 and the second connecting seat 21, the first connecting seat 11 includes a first rotating part 112, and the second connecting seat 21 includes two second rotating parts 212 spaced apart. The first rotating part 112 is rotatably disposed between the two second rotating parts 212, and multiple connecting grooves 111 are disposed on the first rotating part 112 and spaced apart along the direction of the rotation axis 213 of the second connecting seat 21 and the first connecting seat 11.

[0053] At this time, the two second rotating parts 212 of the second connecting seat 21 can clamp the first rotating part 112 of the first connecting seat 11, ensuring that the first connecting seat 11 and the second connecting seat 21 will not move relative to each other in the direction of the rotation axis 213, so that the first connecting seat 11 and the second connecting seat 21 can only rotate relative to each other, avoiding positional deviation between the first circuit board 100 and the second circuit board 200.

[0054] Furthermore, each of the two second rotating parts 212 has a rotating shaft 213 on its inner side, and each of the two ends of the first rotating part 112 has a rotating groove 113. The rotating shaft 213 is inserted into the corresponding rotating groove 113 so that the second connecting seat 21 is rotatably connected to the first connecting seat 11. Both ends of the first rotating part 112 are inserted into the corresponding rotating shaft 213, which ensures the balance of torque when the first connecting seat 11 and the second connecting seat 21 rotate relative to each other, and avoids the first connecting seat 11 being subjected to force on one side, thus increasing the friction between the first rotating part 112 and the second rotating part 212.

[0055] like Figure 5 and Figure 6 As shown, the first rotating part 112 is provided with a plurality of limiting grooves 114 at circumferential intervals along the rotation axis 213 line between the second connecting seat 21 and the first connecting seat 11. The second rotating part 212 is provided with limiting protrusions 214. The limiting protrusions 214 can be inserted into the plurality of limiting grooves 114 to fix the first circuit board 100 and the second circuit board 200 at different angles, which facilitates the operator to assemble.

[0056] The first rotating part 112 can be provided with multiple limiting grooves 114 at both ends, and correspondingly, the two second rotating parts 212 are provided with limiting protrusions 214 to ensure uniform force distribution.

[0057] Furthermore, the first rotating part 112 has multiple limiting grooves 114 that are equally spaced, and the second rotating part 212 has multiple limiting protrusions 214, with each limiting protrusion corresponding to one of the multiple limiting grooves 114. That is, when the first connecting seat 11 rotates relative to the second connecting seat 21, the multiple limiting protrusions 214 simultaneously enter or exit the corresponding limiting grooves 114, which not only ensures that the gap between the first rotating part 112 and the second rotating part 212 is relatively uniform, but also improves the reliability of the limiting.

[0058] In some embodiments, the second rotating part 212 may be provided with a plurality of limiting grooves 114 at circumferential intervals along the rotation axis 213 line between the second connecting seat 21 and the first connecting seat 11, and the first rotating part 112 may be provided with limiting protrusions 214. The limiting protrusions 214 can be engaged in the plurality of limiting grooves 114 so that the first circuit board 100 and the second circuit board 200 are fixed at different angles, which facilitates assembly by the operator.

[0059] The two second rotating parts 212 can each be provided with multiple limiting grooves 114, and correspondingly, the opposite ends of the first rotating part 112 are provided with limiting protrusions 214 to ensure uniform force distribution.

[0060] Furthermore, the second rotating part 212 has multiple limiting grooves 114 that are equally spaced, and the first rotating part 112 has multiple limiting protrusions 214, which correspond one-to-one with the multiple limiting grooves 114. That is, when the first connecting seat 11 rotates relative to the second connecting seat 21, the multiple limiting protrusions 214 enter or move out of the corresponding limiting grooves 114 together, which can ensure that the gap between the first rotating part 112 and the second rotating part 212 is relatively uniform and improve the reliability of the limiting.

[0061] In order to reduce the resistance when the first connecting seat 11 and the second connecting seat 21 rotate relative to each other, the adjacent limiting grooves 114 are connected by an arc groove 115, and the center of the arc groove 115 is located on the rotation axis 213 line between the second connecting seat 21 and the first connecting seat 11.

[0062] In this embodiment, a portion of the first connecting end 121 of the first terminal 12 is embedded in the first rotating part 112. This structure ensures that when the first connecting seat 11 and the second connecting seat 21 rotate relative to each other, the first connecting end 121 of the first terminal 12 remains relatively stable with the first connecting seat 11, thereby ensuring the reliability of the connection between the first connecting end 121 and the second connecting end 221.

[0063] It is worth noting that the connector is connected to the first circuit board 100 only through the first terminal 12 and to the second circuit board 200 only through the second terminal 22. This results in a low connection strength between the connector and the first circuit board 100 or the second circuit board 200. Furthermore, when subjected to external forces, the connection point between the first terminal 12 and the first circuit board 100 or the connection point between the second terminal 22 and the second circuit board 200 is easily damaged.

[0064] like Figure 5 and Figure 6 As shown, to solve the above problems, the first connector 1 includes a first reinforcing connector 13, which is fixedly disposed on the first connector 11 and configured to be fixedly connected to the first circuit board 100. The first reinforcing connector 13 does not need to perform data communication; therefore, its position and size can be designed according to actual needs, thereby providing an additional connection point for the connection between the first connector 11 and the first circuit board 100 and improving the connection strength between them.

[0065] In this embodiment, the first connector 11 includes a first fixing part 116 and a first reinforcing part 117. A plurality of first terminals 12 are fixedly disposed on the first fixing part 116. The first reinforcing part 117 is spaced apart from the first fixing part 116. The first reinforcing connector 13 is C-shaped, partially located between the first fixing part 116 and the first reinforcing part 117. The first reinforcing connector 13 is welded and fixed to the first circuit board 100. The first reinforcing connector 13 partially surrounds the first reinforcing part 117 and is clamped by the first reinforcing part 117 and the first fixing part 116, ensuring that the first reinforcing connector 13 will not detach from the first connector 11, thus improving the connection strength between the first connector 11 and the first circuit board 100.

[0066] Similarly, the second connector 2 includes a second reinforcing connector 23, which is fixedly disposed on the second connector 21 and configured to be fixedly connected to the second circuit board 200. The second reinforcing connector 23 does not need to perform data communication; therefore, its position and size can be designed according to actual needs, thereby providing an additional connection point for the connection between the second connector 21 and the second circuit board 200, and improving the connection strength between them.

[0067] In this embodiment, the second connector 21 includes a second fixing part 216 and a second reinforcing part 215. A plurality of second terminals 22 are fixedly disposed on the second fixing part 216. The second reinforcing part 215 is spaced apart from the second fixing part 216. The second reinforcing connector 23 is C-shaped, partially located between the second fixing part 216 and the second reinforcing part 215. The second reinforcing connector 23 is welded and fixed to the second circuit board 200. The second reinforcing connector 23 partially surrounds the second reinforcing part 215 and is clamped by the second reinforcing part 215 and the second fixing part 216, ensuring that the second reinforcing connector 23 does not detach from the second connector 21, thus improving the connection strength between the second connector 21 and the second circuit board 200.

[0068] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
