[0049] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

Exemplarily, the receiving groove 40 includes a top wall 400 and a bottom wall 401, and the ball 9 contacts the top wall 400 and the bottom wall 401.

[0052] refer to Figures 4 to 6The first joint 5 includes a joint portion 51 and a support portion 52 connected to each other. The support portion 52 is located in the receiving groove 40. A part of the ball 9 is embedded in the support portion 52 to support the support portion 52. The support portion 52 is used to rotate relative to the ball 9. For example, the ball 9 can move relative to the fixed seat 4 in the receiving groove 40. The support portion 52 is in a plate shape. The ball 9 supports the support portion 52 upward. The support portion 52 can rotate relative to the ball 9, that is, the support portion 52 rotates in the receiving groove 40 driven by its joint portion 51. For example, one end of the support portion 52 is tilted upward with the ball 9 located at the other end of the support portion 52 as a fulcrum to support the top wall 400 of the receiving groove 40. In this embodiment, the support portion 52 can rotate at an angle of ±1°, that is, the plane where the support portion 52 is located forms an angle of 1° with the horizontal plane.

[0053] Those skilled in the art will appreciate that, in other embodiments, the rotatable angle of the support portion 52 may also be other values, such as ±2°.

[0054] The joint part 51 is located outside the receiving groove 40, and the joint part 51 includes a plug hole 50. The inner wall of the plug hole 50 is provided with a guide slope 500. Figure 4 The guide slope 500 gradually shrinks from top to bottom. For example, the plug hole 50 is provided with a flat cable 10, which is located at the end of the guide slope 500 in the plug hole 50, that is, the cross-sectional area of ​​the guide slope 500 shrinks to the minimum position.

[0055] Exemplarily, the joint portion 51 and the support portion 52 are both rectangular, and the cross-sectional area of ​​the support portion 52 is larger than that of the joint portion 51, and the joint portion 51 is located at the center of the support portion 52. The plug hole 50 is in a rectangular parallelepiped shape, and its inner wall includes four planes, and the four planes are all provided with guide slopes 500, so that an inverted quadrangular pyramid is formed in the plug hole 50 by the guide slopes 500.

[0056] like Figure 2 , Figure 4 and Figure 6 As shown, the circuit board 6 and the fixing seat 4 are aligned along the height direction ( Figure 2 The second connector 7 is fixed to the circuit board 6, and the second connector 7 is used to be inserted into the plug hole 50 to be electrically connected to the first connector 5. Exemplarily, the second connector 7 is inserted into the plug hole 50 of the first connector 5 and connected to the flat cable 10 in the plug hole 50, thereby realizing the electrical connection between the first connector 5 and the second connector 7.

[0057] Exemplarily, the upper shell 2 and the lower shell 3 are connected, and then the first joint 5 and the second joint 7 are connected.

[0058] The alignment component 8 drives the support portion 52 of the first connector 5 to move in the receiving groove 40, so that the first connector 5 faces the second connector 7 in the height direction. Exemplarily, the alignment component 8 provides a driving force for the support portion 52 of the first connector 5 to move in the receiving groove 40, and the ball 9 senses the driving force through the support portion 52, thereby driving the support portion 52 to move in the receiving groove 40 through the ball 9, thereby facilitating the second connector 7 to be accurately inserted into the plug hole 50 of the first connector 5.

[0059] By adopting the above technical solution, the operator moves the fixing seat 4 so that it moves along the height direction ( Figure 4 4, and the second connector 7 is inserted into the groove 40. The groove 40 is provided with a plurality of grooves, and the plurality of grooves are ...

[0060] refer to Figure 2 , Figure 6 and Figure 7 In some possible implementations, the alignment assembly 8 includes a plurality of first magnets 81 and a plurality of second magnets 82. The plurality of first magnets 81 are symmetrically distributed about the center of the joint portion 51. For example, in this embodiment, four first magnets 81 are provided, and the four first magnets 81 are distributed around the joint portion 51 in a square shape, that is, the joint portion 51 is located at the center of the four first magnets 81.

[0061] A plurality of first magnets 81 are embedded in the support portion 52 of the first connector 5, and the plurality of first magnets 81 are arranged along the height direction ( Figure 2 exemplarily, as shown in the Z direction. Figure 8 As shown, the support portion 52 is provided with four rectangular holes 520 for embedding the first magnet 81 .

[0062] refer to Figure 2 , Figure 6 and Figure 7 , the plurality of second magnets 82 are symmetrically distributed about the center of the second connector 7, the plurality of second magnets 82 are fixed to the circuit board 6, and are all arranged along the height direction ( Figure 2 a plurality of second magnets 82 corresponding to the plurality of first magnets 81 one by one, and each second magnet 82 is arranged opposite to the same pole of the first magnet 81 corresponding to it.

[0063] Specifically, the plurality of first magnets 81 include a first front magnet 811, a first rear magnet 812, a first left magnet 813, and a first right magnet 814. The first front magnet 811 and the first rear magnet 812 are located in the first direction ( Figure 7 The first left magnet 813 and the first right magnet 814 are located on both sides of the joint portion 51 in the second direction ( Figure 7 The first direction, the second direction and the height direction ( Figure 7 Exemplarily, the joint portion 51 is rectangular, and the first front magnet 811, the first rear magnet 812, the first left magnet 813 and the first right magnet 814 are respectively located at the front, back, left and right of the joint portion 51, and are symmetrically distributed about the center of the joint portion 51, that is, the straight-line distances of the first front magnet 811, the first rear magnet 812, the first left magnet 813 and the first right magnet 814 from the center of the joint portion 51 are equal.

[0064] The plurality of second magnets 82 include a second front magnet 821, a second rear magnet 822, a second left magnet 823, and a second right magnet 824. The second front magnet 821 and the second rear magnet 822 are located in the first direction ( Figure 2 The second left magnet 823 and the second right magnet 824 are located on both sides of the second connector 7 in the second direction ( Figure 2 Exemplarily, the second connector 7 is rectangular, and the second front magnet 821, the second rear magnet 822, the second left magnet 823, and the second right magnet 824 are respectively located in the front, back, left, and right of the second connector 7, and are symmetrically distributed about the center of the second connector 7, that is, the straight-line distances of the second front magnet 821, the second rear magnet 822, the second left magnet 823, and the second right magnet 824 from the center of the second connector 7 are equal.

[0065] The first front magnet 811 and the second front magnet 821 have the same poles along the first direction ( Figure 7 The first rear magnet 812 and the second rear magnet 822 are arranged opposite to each other along the first direction. For example, in this embodiment, the N poles of the first front magnet 811 and the second front magnet 821 are arranged opposite to each other along the first direction ( Figure 7 The N poles of the first rear magnet 812 and the second rear magnet 822 are arranged relatively to each other along the first direction.

[0066] Due to the principle that like poles of magnets repel each other, the first front magnet 811 and the second front magnet 821 as well as the first rear magnet 812 and the second rear magnet 822 generate repulsive forces against each other. The repulsive force of the second front magnet 821 drives the support portion 52 with the first front magnet 811 to move along the first direction and toward the first rear magnet 812. Similarly, the repulsive force of the second rear magnet 822 drives the support portion 52 with the first rear magnet 812 to move along the first direction and toward the first front magnet 811. When the first connector 5 is located in the middle position between the second front magnet 821 and the second rear magnet 822, the repulsive forces on both sides of the support portion 52 of the first connector 5 in the first direction are equal, so that the first connector 5 is maintained in the middle position between the second front magnet 821 and the second rear magnet 822. At this time, the projection of the second connector 7 in the height direction is flush with the first connector 5 in the first direction.

[0067] The same poles of the first left magnet 813 and the second left magnet 823 are arranged along the second direction ( Figure 7 The first right magnet 814 and the second right magnet 824 are arranged opposite to each other along the second direction. Figure 7 The first right magnet 814 and the second right magnet 824 are arranged oppositely along the second direction.

[0068] Due to the principle that like poles of magnets repel each other, the first left magnet 813 and the second left magnet 823 as well as the first right magnet 814 and the second right magnet 824 generate repulsive forces against each other. The repulsive force of the second left magnet 823 drives the support portion 52 with the first left magnet 813 to move along the second direction and toward the first right magnet 814. Similarly, the repulsive force of the second right magnet 824 drives the support portion 52 with the first right magnet 814 to move along the second direction and toward the first left magnet 813. When the first connector 5 is located in the middle position between the second left magnet 823 and the second right magnet 824, the repulsive forces on both sides of the support portion 52 of the first connector 5 in the second direction are equal, so that the first connector 5 is maintained in the middle position between the second left magnet 823 and the second right magnet 824. At this time, the projection of the second connector 7 in the height direction is flush with the first connector 5 in the second direction.

[0069] Then the first connector 5 is located in the first direction ( Figure 7 The Y direction is shown in the middle position of the magnet 820, and the magnet 821 is located in the middle position of the magnet 820 in the second direction ( Figure 7The second front magnet 821, the second rear magnet 822, the second left magnet 823 and the second right magnet 824 are symmetrically distributed about the center of the second joint 7. That is to say, the first joint 5 and the second joint 7 are in the height direction ( Figure 7 The first connector 5 is arranged opposite to the second connector 7 (as shown in the Z direction), so that the first connector 5 can be directly moved up to connect with the second connector 7, which is beneficial to reducing the clearance between the first connector 5 and the second connector 7 and improving the communication stability.

[0070] That is, in this embodiment, by setting the Figure 7 The two pairs of magnets (the first front magnet 811 and the second front magnet 821, the first rear magnet 812 and the second rear magnet 822) on the second direction ( Figure 7 The two pairs of magnets (the first left magnet 813 and the second left magnet 823, the first right magnet 814 and the second right magnet 824) on the upper surface of the first connector 5 (as shown in the X direction) limit the position of the first connector 5 in two directions so that it is directly opposite to the second connector 7 in the height direction, so as to facilitate the first connector 5 to move up and be electrically connected to the second connector 7.

[0071] Those skilled in the art will appreciate that in other embodiments, other numbers of first magnets 81 and second magnets 82 may be provided so that their centers are symmetrically distributed around the joint portion 51 of the first joint 5 and the second joint 7, such as 6, 8, etc., so as to achieve alignment of the first joint 5 and the second joint 7 in the height direction.

[0072] In some possible implementations, such as Figure 4 , Figure 7 and Figure 8 As shown, the support portion 52 is provided with a spherical hole 521 extending in the height direction ( Figure 4 The diameter of the spherical hole 521 gradually decreases from bottom to top; a portion of the ball 9 is embedded in the spherical hole 521, and the upper end of the ball 9 protrudes upward from the support portion 52, so that the ball 9 supports the support portion 52. Exemplarily, the spherical hole 521 is provided through the support portion 52, and a portion of the ball 9 is embedded in the spherical hole 521, so as to ensure that the ball 9 stably supports the support portion 52, so that under the repulsive force generated by the second magnet 82 and the first magnet 81, the ball 9 drives the support portion 52 to move horizontally in the receiving groove 40, so that the first joint 5 and the second joint 7 are arranged opposite to each other in the height direction. On the other hand, the ball 9 is partially embedded in the spherical hole 521 to support the support portion 52, which also facilitates the support portion 52 to rotate slightly relative to the ball 9 driven by the joint portion 51.

[0073] In some possible implementations, such as Figure 2 and Fig. 9As shown, the fixing base 4 includes an upper cover 41 and a base 42. The bottom of the upper cover 41 is provided with a groove 410. The upper cover 41 and the base 42 are connected in the height direction ( Figure 2 The groove 410 and the upper surface of the base 42 are fitted and connected (shown in the Z direction), and the groove 410 and the upper surface of the base 42 form the receiving groove 40; the lower end of the ball 9 contacts the upper surface of the base 42, and the upper end contacts the top wall of the groove 410. That is, the upper surface of the base 42 is the bottom wall 401 of the receiving groove 40.

[0074] In some possible implementations, a through hole 411 is provided on the top of the upper cover 41. The through hole 411 is provided along the height direction ( Figure 2 The through hole 411 is connected to the groove 410 (shown in the Z direction), and the cross-sectional area of ​​the through hole 411 is smaller than the cross-sectional area of ​​the groove 410. The through hole 411 allows the joint portion 51 to extend to connect the second joint 7. Exemplarily, since the cross-sectional area of ​​the joint portion 51 of the first joint 5 is smaller than the cross-sectional area of ​​the support portion 52, the cross-sectional area of ​​the through hole 411 is set to be smaller than the cross-sectional area of ​​the groove 410, so that the joint portion 51 extends out, and the top wall 400 of the accommodating groove 40 is formed to relatively limit the support portion 52 of the first joint 5, that is, to form a connection between the fixing seat 4 and the first joint 5.

[0075] In some possible implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, a plurality of third magnets 11 are disposed on the upper surface of the base 42 of the fixing seat 4. The plurality of third magnets 11 correspond to the plurality of first magnets 81 one by one, and each third magnet 11 and the corresponding first magnet 81 have the same pole along the height direction ( Figure 4 The third magnet 11 and the first magnet 81 are arranged relatively to each other (as shown in the Z direction) to drive the support portion 52 of the first connector 5 to move upward in the height direction in the receiving groove 40. Exemplarily, the third magnet 11 and the first magnet 81 have the same poles that repel each other, providing a driving force for the first connector 5 to move upward, so as to prevent the support portion 52 from being stuck on the ball 9 and unable to move up and down, thereby hindering the connection between the first connector 5 and the second connector 7.

[0076] Exemplarily, the third magnet 11 also has four, namely, the third front magnet 111, the third rear magnet 112, the third left magnet 113 and the third right magnet 114, which correspond to the aforementioned first front magnet 811, the first rear magnet 812, the first left magnet 813 and the first right magnet 814. However, those skilled in the art will appreciate that in other embodiments, other numbers of third magnets 11 and first magnets 81 may be provided, such as 5, 6, etc., as long as the driving force for the support portion 52 of the first joint 5 to move upward can be provided.

[0077] In some possible implementations, such as Figure 4 and Figure 7As shown, the side wall of the fixing seat 4 is provided with a Figure 7 The long slot 402 extends in the first direction (Z direction) of the fixing seat 4, and the side of the long slot 402 facing the center of the fixing seat 4 is connected to the receiving slot 40, and the long slot 402 is for the second magnet 82 to be inserted.

[0079] In other embodiments, at least two positioning grooves 210 among the plurality of positioning grooves 210 have different shapes.

[0080] In another embodiment, at least two positioning grooves 210 among the plurality of positioning grooves 210 have different depths.

[0081] That is to say, at least two positioning grooves 210 among the plurality of positioning grooves 210 may only be different in shape, or only be different in depth, or may be different in both shape and depth, and the present application does not impose any limitation on this.

[0082] Exemplarily, in this embodiment, the upper chamber 20 is rectangular, and the positioning grooves 210 include four, namely a first positioning groove 211, a second positioning groove 212, a third positioning groove 213 and a fourth positioning groove 214, and are distributed in the four corners of the upper chamber 20 in a rectangular shape.

[0083] Specifically, the first positioning groove 211 and the second positioning groove 212 are arranged in a first direction ( Figure 3 The third positioning groove 213 and the fourth positioning groove 214 are arranged oppositely in the first direction, and the first positioning groove 211 and the fourth positioning groove 214 are arranged oppositely in the second direction ( Figure 3The second positioning groove 212 and the third positioning groove 213 are arranged relatively in the second direction. The first positioning groove 211, the second positioning groove 212 and the third positioning groove 213 have the same shape and are all cylindrical, but have different depths. The depth of the first positioning groove 211 is deeper than that of the second positioning groove 212 and the third positioning groove 213. The fourth positioning groove 214 has the same depth as the first positioning groove 211, but has a different shape. The cross-section of the fourth positioning groove 214 is an arc shape greater than 180 degrees. In other words, the fourth positioning groove 214 is different from the second positioning groove 212 and the third positioning groove 213 in shape and depth.

[0084] Likewise, the positioning posts 310 in this embodiment also include a first positioning post 311 , a second positioning post 312 , a third positioning post 313 and a fourth positioning post 314 , and the shapes and heights thereof match the corresponding positioning slots 210 .

[0085] Exemplarily, the first positioning column 311 is inserted into the first positioning groove 211, the second positioning column 312 is inserted into the second positioning groove 212, the third positioning column 313 is inserted into the third positioning groove 213, and the fourth positioning column 314 is inserted into the fourth positioning groove 214, so as to realize the connection between the upper shell 2 and the lower shell 3, and the difference in shape and size (i.e., the depth of the positioning groove 210 and the height of the positioning column 310) between the positioning column 310 and the positioning groove 210 enables the upper shell 2 and the lower shell 3 to be accurately connected, ensuring that the upper shell 2 and the lower shell 3 have only a unique assembly direction and assembly position, thereby effectively controlling the assembly error while reducing costs. On the other hand, it also improves the accuracy of the connection between the first joint 5 and the second joint 7 to a certain extent.

[0086] The present application does not limit the specific differences in the shapes and sizes of the positioning column 310 and the positioning groove 210 (i.e., the depth of the positioning groove 210 and the height of the positioning column 310). In other embodiments, positioning columns 310 and positioning grooves 210 of other shapes and sizes may also be provided, such as rectangular positioning grooves 210 and positioning columns 310, triangular prism-shaped positioning grooves 210 and positioning columns 310, etc. The sizes thereof may also be flexibly set and may be selected according to actual needs.
