[0034] Embodiment 1:

[0035] Reference Figures 1 to 4 , an embodiment of the present application provides a connection structure, exemplarily, the connection structure can be applied to a connector of an automobile, and the connection structure includes a first connection member 10 and a second connection member 20. The first connection member 10 includes a base 11, a first connection portion 12 and a second connection portion 13, and the base 11 includes two first ends 111 disposed in opposite directions, two second ends 112 disposed in opposite directions and two third ends 113 disposed in opposite directions. At least one side surface of the first connection portion 12 away from the base 11 is recessed to form a first tooth row 121. In this embodiment, both sides of the first connection portion 12 away from the base 11 are recessed to form two first tooth rows 121. Arranging the first tooth rows 121 on multiple sides is conducive to increasing the meshing connection force of the connection structure, thereby facilitating further increasing the connection stability of the connection structure. While the first connection portion 12 is convexly disposed on the first end 111 relative to the second end 112, the first connection portion 12 is also bent relative to the third end 113. The first tooth row 121 is disposed relative to or away from the second end 112. The second connection portion 13 is protruded from the base 11 relative to the second end 112, and the second connection portion 13 is fixed in the second connection member 20. The second connection member 20 is provided with a first mounting hole 201, and the hole wall of the first mounting hole 201 is provided with a second tooth row 21. The first connection portion 12 is fixed in the first mounting hole 201, and the first tooth row 121 is meshed with the second tooth row 21. In this embodiment, each first tooth row 121 is meshed with a second tooth row 21.

[0036] In the present application, the bite force between the first connecting member 10 and the second connecting member 20 is increased by the cooperation of the second connecting member 20, the first tooth row 121, the second tooth row 21 and the second connecting portion 13, thereby increasing the connection stability of the connection structure and further reducing the risk of failure of the connection structure.

[0037] In some embodiments, reference Figure 2 and Figure 3 The first tooth row 121 includes a first meshing surface 1211 and a second meshing surface 1212 that are alternately arranged. The first meshing surface 1211 serves as a guide surface. When viewed along the extension direction of the first connection portion 12, that is, when viewed from the end of the first connection portion 12 connected to the base 11 to the end of the first connection portion 12 away from the base 11, the first meshing surface 1211 is inclined, and the second meshing surface 1212 is vertically arranged, so that the cross section of the tooth portion of the first tooth row 121 is a trapezoidal structure or a triangular structure. The second tooth row 21 includes a third meshing surface 211 and a fourth meshing surface 212 that are alternately arranged. The third meshing surface 211 is abutted against the first meshing surface 1211, that is, the third meshing surface 211 is also inclined, and the fourth meshing surface 212 is abutted against the second meshing surface 1212, that is, the fourth meshing surface 212 is also vertically arranged. The shape of the tooth row is conducive to further increasing the bite force between the first connecting member 10 and the second connecting member 20, thereby helping to further reduce the risk of connection failure of the connecting structure.

[0038] In some embodiments, the second connection portion 13 is disposed at the third end 113, so that the first connection portion 12 is also bent relative to the second connection portion 13, and the tops of the first tooth row 121 are flush. The structural arrangement of the first connection member 10 is conducive to improving strength, thereby facilitating improving tolerance to torsional deformation.

[0039] In some embodiments, a first through hole 132 is disposed at one end of the second connection portion 13 close to the base 11, and the first through hole 132 is disposed opposite to the other third end 113. Figure 4 , the second connector 20 also passes through the first through hole 132. The second connector 20 passing through the first through hole 132 is conducive to increasing the connection sites between the first connector 10 and the second connector 20, thereby further increasing the connection stability of the first connector 10 and the second connector 20, and further reducing the risk of failure.

[0040] In some embodiments, the first connector 10 is a metal part, and the second connector 20 is a plastic part. The first connector 10 and the second connector 20 can be fixed by plastic injection molding, and the first connector 10 can be used for conducting electricity. The second connector 13 is protruded from the second connector 20 at one end away from the base 11, and the end surface of the second connector 13 away from the base 11 is recessed to form a slot 131, and the slot 131 is used to install the wire 31 of the electronic component 30. The structure of the second connector 13 is conducive to increasing the convenience of installing the wire 31, and therefore, it is conducive to improving the convenience of using the connection structure.

[0041] In specific applications, for example, each connection structure may include a second connection member 20 and a plurality of first connection members 10, and the second connection portion 13 of a portion of the first connection members 10 may be used to connect the positive lead of the electronic component 30, and the second connection portion 13 of another portion of the first connection members 10 may be used to connect the negative lead of the electronic component 30. Similarly, each connection structure may include a second connection member 20 and a first connection member 10, and in specific applications, the second connection portion 13 of the first connection member 10 of one connection structure may be used to connect the positive lead of the electronic component 30, and the second connection portion 13 of the first connection member 10 of another connection structure may be used to connect the negative lead of the electronic component 30.

[0042] In some embodiments, there are two first connection parts 12, each of which is disposed at a first end 111. The arrangement of the first connection parts 12 is conducive to improving the force balance while increasing the connection points, thereby further improving the connection stability while also improving the torsional resistance, so that when torque and tension are applied to the first connection member 10, the first connection member 10 is not prone to displacement and deformation.

[0043] In some embodiments, the base 11 is provided with a second through hole 110 , and the second through hole 110 passes through end surfaces of the two second ends 112 .

[0044] The connection structure of this embodiment can withstand the installation torque of the bolt M6x1.0Max.9.0Nm.

[0047] In some embodiments, the tops of the teeth of the first tooth row 121' are arranged obliquely, and the tops of the teeth of the first tooth row 121' closest to the base 11 protrude from the other tops of the teeth of the first tooth row 121'. The second connecting portion 13 is arranged at the first end 111, and the first connecting portion 12' and the second connecting portion 13 are arranged relative to different second ends 112. In this embodiment, the number of the second connecting portions 13 can be two.
