[0046] The utility model relates to a connector 10, which is used to connect the two ends of two pieces to be connected 20. The two pieces to be connected 20 can be two magnetic strips to be connected, or other strips to be connected, such as Figure 4 As shown, the cross section of the member to be connected 20 is generally rectangular.

[0047] Specifically, Figure 1-3 As shown, the connector 10 includes a base 1 and a cover 2, the base 1 extends along a first direction X and has a bottom mounting groove 11, the bottom mounting groove 11 is formed by a depression on the top surface of the base 1 and passes through both ends of the base 1 along the first direction X, for avoiding two connecting members 20.

[0048] The cover 2 also extends along the first direction X and is connected to the top of the base 1, and the cover 2 can cover the top opening of the bottom mounting groove 11 of the base 1. The cover 2 is provided with a top mounting groove 21, which also extends along the first direction X and passes through both ends of the cover 2 along the first direction X. After the cover 2 covers the top of the base 1, the top mounting groove 21 and the bottom mounting groove 11 are aligned in the vertical direction, and form a cavity for accommodating the opposite ends of the two pieces 20 to be connected.

[0049] During installation, the two connecting members 20 are arranged along the first direction X and the bottoms of the two connecting members 20 are located in the bottom mounting groove 11 and the tops are located in the top mounting groove 21. The cover 2 and the base 1 respectively fix the two ends of the two connecting members 20.

[0050] The two sides of the cover body 2 along the second direction Y are defined as a first side 24 and a second side 25 respectively.

[0051] The side wall of the top mounting groove 21 along the second direction Y gradually deviates from the center of the top mounting groove 21 along the second direction Y from the top to the bottom, wherein the side wall of the top mounting groove 21 close to the second side 25 includes a middle side wall 26 and two end side walls 23, such as Figure 8As shown, the middle section side wall 26 has a top 261 and a bottom 262, and the middle section side wall 26 is an arc surface that gradually deviates from the center of the top mounting groove 21 along the second direction Y from the top 261 to the bottom 262. The side walls 23 at both ends have a top 231 and a bottom 232 in the vertical direction, and the side walls 23 at both ends are inclined surfaces 23 that gradually deviate from the center of the top mounting groove 21 along the second direction Y from the top 231 to the bottom 232, and the inclined surfaces 23 gradually deviate from the top 231 to the bottom 232 toward the center away from the top mounting groove 21. The side wall of the top mounting groove 21 close to the first side 24 is also an arc surface that gradually deviates from the center of the top mounting groove 21 along the second direction Y from the top to the bottom, and the side wall of the top mounting groove 21 close to the first side 23 is provided with end plates 81 at both ends along the second direction, and the two end plates 81 are respectively aligned with the side walls 23 at both ends of the top mounting groove 21 close to the second side 25, which will be described in detail below.

[0052] The second direction Y is perpendicular to the first direction X, that is, the two side directions of the cover body 2. The side wall of the top mounting groove 21 along the second direction Y gradually deviates from the center of the top mounting groove 21 along the second direction Y from the top to the bottom, so that the bottom opening size of the top mounting groove 21 becomes larger, that is, the size of the top mounting groove 21 along the second direction Y gradually increases from the top to the bottom.

[0053] During installation, first place the two ends of the two pieces 20 to be connected in the bottom mounting groove 11 of the base 1, the bottoms of the two pieces 20 to be connected are located in the bottom mounting groove 11, and the tops of the two pieces 20 to be connected exceed the top of the base 1. When the cover 2 is covered on the base 1, its top mounting groove 21 is buckled on the tops of the two pieces 20 to be connected and fixed in the top mounting groove 21. Since the side walls of the top mounting groove 21 along the second direction Y gradually deviate from the center of the top mounting groove 21 along the second direction, that is, the middle side wall 26 and the side walls 23 at both ends make the size of the top mounting groove 21 along the second direction Y gradually increase from top to bottom, so as to prevent the top corners 201 of the two pieces 20 to be connected from being damaged when the cover 2 is covered on the tops of the two pieces 20 to be connected.

[0054] like Figure 6 As shown, the first side 24 is rotatably connected to the base 1 through a flexible connecting belt 7, which can be a cloth belt or a plastic belt, etc., and the specific form of the flexible connecting belt 7 is not limited. In this embodiment, the connecting belt 7 is integrally formed with the base 1 and the cover 2. The second side 25 is connected to the base 1 by a buckle. Figure 6In the illustrated embodiment, a slot 22 is provided at the bottom end of the second side 25, and a hook 12 that can be engaged with the slot 22 is provided at the top end of the base 1. In other embodiments, a hook 12 may also be provided at the bottom end of the second side 25, and a slot 22 that accommodates the hook 12 may be provided at the top end of the base 1. Of course, the second side 25 may also be detachably connected to the base 1 in other ways, such as magnetic attraction, bonding, or screws, etc., and the specific connection method between the second side 25 and the base 1 is not limited.

[0055] The side wall of the top mounting groove 21 close to the first side 24 may also be configured as an inclined surface or an arc surface that gradually deviates from the center of the second direction Y of the top mounting groove 21 from the top end to the bottom end, and the angle between the inclined surface of the side wall of the top mounting groove 21 close to the first side 24 and a normal line L extending in the vertical direction may be smaller than the angle between the side wall of the top mounting groove 21 away from the first side 24 and the normal line L.

[0056] After the two connected parts 20 are installed at the bottom of the base 1, the first side 24 of the cover body 2 is connected to the base 1, and the side wall of the top mounting groove 21 close to the second side 25 needs to avoid the top edge 201 of the two connected parts 20 close to the second side 25, so the angle between the top mounting groove 21 close to the second side 25 and the normal L needs to be slightly larger.

[0057] The angle formed by the side walls 23 at both ends of the top mounting groove 21 away from the first side 24 and a normal line L extending in the vertical direction is defined as α, preferably, 20°≤α≤40°, and the angle of α can be selected from 20°, 25°, 30°, 35°, 40°, etc., which can ensure that the top edge 201 of the connected component 20 close to the second side 25 is avoided.

[0058] The connector 10 also includes a first limiting structure, which is located in the bottom mounting groove 11 and connected to the inner wall of the bottom mounting groove 11. The first limiting structure includes two limiting plates 3 and a plurality of support plates 31 that are arranged opposite to each other along the second direction Y. The two limiting plates 3 extend along the first direction X and are arranged opposite to each other along the second direction Y. The bottom ends of the two limiting plates 3 are connected to the bottom wall of the bottom mounting groove 11. The plurality of support plates 31 are respectively used to support the two limiting plates 3. Some of the supporting plates 31 in the plurality of supporting plates 31 are arranged at intervals along the first direction X and are connected to a side of one of the limiting plates 3 that is away from the other limiting plate 3. The part of the supporting plates 31 abuts against one side wall of the bottom mounting groove 11 in the second direction Y. Another part of the supporting plates 31 are arranged at intervals along the first direction X and are connected to another limiting plate 3. The other part of the supporting plates 31 abuts against another side wall of the bottom mounting groove 11 in the second direction Y.

[0059] The limiting plate 3 has a top end 301 and a bottom end 302, and the distance between the two limiting plates 3 gradually increases from the bottom end 302 to the top end 301, which facilitates the two connected parts 20 to be installed between the two limiting plates 3 from the top end 301, and can also limit the movement of the two connected parts 20 along the second direction Y.

[0060] Optionally, the sides of the two limit plates 3 facing each other are inclined surfaces that gradually deviate from the center of the bottom mounting groove 11 along the second direction Y from the bottom end 302 to the top end 301, that is, the inner side surfaces 32 of the two limit plates 3 are both inclined surfaces, and the angle formed by the inclined surface and a normal line L extending in a vertical direction is γ, which is relatively small, preferably 0°<γ≤1°. The top ends of the two limit plates 3 are slightly inclined toward the two sides of the base 1 along the second direction Y, which facilitates the installation of the two to-be-connected members 20, and does not affect the limiting effect of the limit plates 3 on the to-be-connected members 20.

[0061] In one embodiment, one of the two limiting plates 3 is parallel to the normal line L, that is, the inner side surface 32 of the limiting plate 3 is not an inclined surface but a vertical surface. The inner side surface 32 of the other limiting plate 3 is an inclined surface, and the angle of the inclined surface may be slightly greater than γ.

[0062] In addition, the inner side surface of the top 301 of one of the limiting plates 3 is flush with the side wall of the top mounting groove 21 close to the first side 24, and the inner side surface of the top 301 of the other limiting plate 3 is flush with the top of the side wall of the top mounting groove 21 close to the second side 25. After the two to-be-connected members 20 are installed on the connector 10, the side wall of the top mounting groove 21 close to the first side 24 can also limit the two to-be-connected members 20, while the inclined surface close to the second side 25 needs to avoid the top corner 201 of the to-be-connected member 20, so it is spaced apart from the to-be-connected member 20.

[0063] The connector 10 also includes a middle partition, which is located in the middle of the top mounting groove 21 and the bottom mounting groove 11 along the first direction X. The middle partition is located in the middle of the base 1 and the cover body 2 along the first direction X, that is, the middle partition divides the base 1 and the cover body 2 into two symmetrically arranged parts.

[0064] During installation, the two members to be connected 20 are respectively located on both sides of the middle partition along the first direction X, and the middle partition is located between the ends of the two members to be connected 20 .

[0065] Since the base 1 and the cover 2 are symmetrically arranged relative to the middle partition, there is no need to consider the orientation matching problem between the connector 10 and the connected component 20 during installation, thereby improving assembly efficiency.

[0066] exist Figure 5In the specific embodiment shown, the partition includes a top plate 61 and a bottom plate 6, wherein the top plate 61 is located in the top mounting groove 21 and connected to the inner wall of the top mounting groove 21, the top plate 61 is located at the center of the cover body 2 along the first direction X, and the top plate 61 divides the bottom mounting groove 11 into two symmetrical parts. The bottom plate 6 is located in the bottom mounting groove 11 and connected to the inner wall of the bottom mounting groove 11, the bottom plate 6 is located at the center of the base 1 along the first direction X, and the top surface of the bottom plate 6 abuts against the top plate 61. The bottom plate 6 divides the bottom mounting groove 11 into two symmetrically arranged parts.

[0067] The thickness of the partition along the first direction X does not exceed 2 mm, and the optional range includes but is not limited to 1 mm, 1.5 mm and 2 mm. It is preferably greater than 1 mm and less than 1.5 mm, which can ensure that the ends of the magnetic strip are as tightly fitted as possible after installation, and can also ensure the mechanical strength of the connector 10 itself.

[0068] Optionally, in some embodiments, the partition may be an integral plate, and the partition may be connected to the top mounting groove 21 or the bottom mounting groove 11. Optionally, in some embodiments, the partition may also be located slightly toward either end of the base 1 and the cover 2, that is, the partition is not disposed in the middle of the base 1 and the cover 2.

[0069] The connector 10 further includes a second limiting structure, which includes a plurality of protrusions 4 disposed on the top wall of the top mounting groove 21 and the bottom wall of the bottom mounting groove 11, and is used to abut against the top and bottom surfaces of the two ends of the two pieces 20 to be connected, further limiting the movement of the two pieces 20 to be connected in the vertical direction. It should be understood that in other embodiments, the top surfaces of the two pieces 20 to be connected are tightly abutted against the top wall of the top mounting groove 21, and the plurality of protrusions 4 are disposed on the bottom wall of the bottom mounting groove 11 and abut against the bottom surfaces of the two pieces 20 to be connected. In another embodiment, the bottom surfaces of the two pieces 20 to be connected are tightly matched with the bottom wall of the bottom mounting groove 11, and the plurality of protrusions 4 are disposed on the top wall of the top mounting groove 21 and abut against the top surfaces of the two pieces 20 to be connected.

[0070] After the two magnetic strips (i.e., the connecting parts 20) are connected, if the distance between the ends of the two magnetic strips is too far, the mowing robot will not recognize the two magnetic strips connected together as one magnetic strip, which affects the recognition of the boundary. When the distance between the ends of the two magnetic strips is greater than a certain distance D, when the mowing robot walks along the magnetic strips and passes the interface, it will be able to detect a significant change in the magnetic field intensity, and then the connected magnetic strips will not be recognized by the robot, causing the robot to end walking along the magnetic strips at the interface.

[0071] exist Figure 6In the illustrated embodiment, a plurality of protrusions 4 are arranged at intervals along the first direction, and two protrusions 4 near the base 1 or the cover 2 at both ends along the first direction are respectively used to limit the movement of the two magnetic strips in the vertical direction, that is, the spacing between the two outermost protrusions cannot be greater than D, so that the distance between the ends of the magnetic strips connected via the connector 10 can be ensured not to be greater than D. In this embodiment, D≤50mm, and the options include but are not limited to 10mm, 20mm, 30mm, 40mm and 50mm.

[0072] Optionally, the connector 10 further includes a third limiting structure, which includes three pairs of end plate groups, each pair of end plate groups includes two end plates. Two pairs of end plate groups are first end plate groups 5, which are respectively located at two ends of the bottom mounting groove 11 along the first direction X and connected to the inner wall of the top mounting groove 21.

[0073] The two end plates 51 of each pair of first end plate groups 5 are arranged relatively spaced apart along the second direction Y, and the spacing between the two end plates 51 is aligned with the spacing between the two limiting plates 3 along the first direction X, so as to facilitate the insertion of the connected member 20 therein.

[0074] The distance between the two end plates 51 is slightly greater than the distance between the two limit plates 3. Specifically, the end plate 51 has a top end 511 and a bottom end 512, and the distance between the opposite sides of the two end plates 51 of the first end plate group 5 gradually increases from the top end 511 to the bottom end 512, and the angle formed by the opposite sides of the two end plates 51 and the normal line L extending in a vertical direction is β, β>γ. Preferably, 1°<β≤3°, and β can optionally include 1.5°, 2° and 3°.

[0075] The member 20 to be connected is located between the two end plates 51 of the two first end plate groups 5, and the two sides of the member 20 to be connected along the second direction Y abut against the two end plates 51. The two end plates 51 can also limit the movement of the member 20 to be connected along the second direction Y. It should be understood that in other embodiments, at least one first end plate group 5 can also be provided, and the first end plate group 5 can be provided at any end of the bottom mounting groove 11 along the first direction X and the two end plates 51 of the first end plate group 5 are relatively spaced apart along the second direction Y, so as to limit the movement of one of the two members 20 to be connected along the second direction Y.

[0076] The other pair of end plate groups is the second end plate group 8. The two end plates 81 of the second end plate group 8 are respectively located at the two ends of the top mounting groove 21 along the first direction X and connected to the inner wall of the top mounting groove 21. In addition, the two end plates 81 are respectively arranged opposite to each other along the first direction X and are located at the position of the cover body 2 away from the second side 25, that is, the position close to the first side 24. In addition, the two end plates 81 are also respectively arranged opposite to the two end side walls 23 of the top mounting groove 21 close to the second side 25 along the second direction Y. The two end side walls 23 need to avoid the top corners 201 of the to-be-connected member 20 close to the second side 25, and the two end plates 81 can limit the range of motion of the to-be-connected member 20 along the second direction.

[0077] The end plate 81 has a top end 811 and a bottom end 812. After the cover body 2 is covered on the base 1, the side of the two end plates 81 facing the second side 25 gradually deviates from the center of the top mounting groove 21 along the second direction Y from the top end 811 to the bottom end 812. Preferably, the bottom ends 812 of the two end plates 81 are aligned with the top ends 511 of the end plate 51, and the angles between the two end plates 81 and the normal line L are complementary to β, so as to facilitate the installation of the connected component 20.

[0078] Preferred embodiments of the present invention have been described in detail above, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.
