As shown in fig. 1, fig. 4, fig. 8 to fig. 10 and fig. 13 to fig. 15, when the first connecting piece 1 is correspondingly assembled to the second connecting piece 5 along the second direction (i.e., the y-axis direction), the connecting portion 20 is inserted into the tapered positioning groove 71, the connecting piece 30 is accommodated in the accommodating groove 72, and as shown in fig. 15, the positioning portion 80 abuts against the closed end 312 of the connecting piece 30, as shown in fig. 1, fig. 9 and fig. 14, in the process of inserting the connecting portion 20 into the tapered positioning groove 71, the open end 311 of the sliding groove 31 faces the opposite direction (i.e., the negative direction of the y-axis) of the second direction, at this time, the lower side edge of the connecting piece 30 protruding further in the first direction abuts against the positioning portion 80, so that the positioning portion 80 deforms and moves in the first direction (i.e., the x-axis direction), and when the first connecting piece 1 abuts against the closed end 80 in the second direction (i.e., the negative direction) is pushed against the connecting piece 30, and the connecting piece 1 is prevented from moving in the opposite direction (i.e., the first direction) of the connecting piece 80 abuts against the second direction (i.e., the positive direction) of the connecting piece 30) when the connecting piece 1 abuts against the closed end 312 in the opposite direction (i.e., the negative direction) in fig. the second direction) and the connecting piece 30 is prevented from moving in the opposite direction (i.e., the opposite direction of the first direction) from moving direction (i.81) from the connecting piece 1) to the connecting piece 30) when the connecting piece 1 is pushed against the connecting piece is pushed to the connecting piece 1, the connection relationship between the first connector 1 and the second connector 5 can be easily released.
As shown in fig. 1, 4, 10-12 and 15-17, when the first connector 1 is assembled to the second connector 5 and the first connector 1 is separated from the second connector 5, the first connector 1 is rotated 180 ° about the first direction (i.e. the x-axis direction) as shown in fig. 10-12, and then the first connector 1 is moved away from the second connector 5 in the second direction, i.e. as shown in fig. 17, so that the opening end 311 of the chute 31 is turned from the upper direction to the lower direction, and the limited protrusion 81 limited to the closed end 312 is released due to the opening end 311 being oriented downward (i.e. the positive direction of the y-axis), so that the first connector 1 can be smoothly moved in the opposite direction (i.e. the negative direction of the y-axis) of the second direction until the coupling member 30 is separated from the accommodating groove 72.
In detail, in the present embodiment, after the first connector 1 is assembled with the second connector 5, the direction from the closed end 312 to the open end 311 of the first connector 1 is opposite to the second direction (in the present embodiment, the negative direction of the y-axis), the first connector 1 is rotated 180 ° relative to the second connector 5, the direction from the closed end 312 to the open end 311 is the same as the second direction (in the present embodiment, the positive direction of the y-axis), so that the first connector 1 is moved relative to the second connector 5 in the opposite direction (even if the first connector 1 is away from the second connector 5), the closed end 312 does not contact the positioning portion 80, the positioning portion 80 is not deformed, and the first connector 1 and the second connector 5 can be easily released from each other. Therefore, when the first connector 1 and the second connector 5 are to be separated, they are rotated by 90 degrees, 120 degrees or 150 degrees with respect to each other about the first direction as the rotation axis.
Therefore, through the structural geometric design of the first connecting piece 1 and the second connecting piece 5, the two parts can be prevented from deforming through a rotary withdrawing mode in the separating process, so that the probability of permanent deformation of the positioning parts (80, 80 a) is reduced, and the product quality and the service life are improved.

In the present embodiment, the first inclined surface 3121 and the second inclined surface 3122 are symmetrical to each other, and the first side surface 3123 and the second side surface 3124 are parallel to each other in addition to being symmetrical to each other. In some embodiments, the first side 3123 and the second side 3124 may not be parallel to each other and may be angled with respect to each other, for example, 30 degrees, 45 degrees, 60 degrees, or the like.
As shown in fig. 4 to 5, 9 and 14, the bump 81 of the positioning portion 80 in the first embodiment has an inclined surface 811, and the inclined surface 811 is far from the movable end 821, in this embodiment, one half of the bump 81 has a cylindrical block shape, and the other half has a trapezoidal block shape, and the direction of the inclined surface 811 further away from the movable end 821 is closer to the substrate 50, and in other embodiments, the inclined surface 811 has an elliptical inclined surface shape, a triangular inclined surface shape, and other polygonal inclined surface shapes.

By this, when the first connector 1 is assembled to the second connector 5 in the second direction, the joint 30 can be pushed and pushed smoothly under the guide of the inclined surfaces (811, 811 a) by the arrangement of the inclined surfaces (811, 811 a) on the positioning portions (80, 80 a), so that the positioning portions (80, 80 a) of the second connector 5 can be moved and deformed in the first direction.
As shown in fig. 1 and fig. 8 to 17, the first connecting member 1 further includes a guide groove 40, the guide groove 40 includes an open side 41 and a closed side 42 opposite to each other, and a direction from the closed side 42 to the open side 41 of the guide groove 40 is different from a direction from the closed end 312 to the open end 311 of the chute 31, so that when the first connecting member 1 is assembled to the second connecting member 5 along the second direction by the arrangement of the guide groove 40, the positioning portion 80 of the second connecting member 5 can be smoothly guided to deform in the first direction (i.e., the x-axis direction). In this embodiment, the direction of the channel 40 from the closed side 42 to the open side 41 is the same as the second direction (i.e., the y-axis direction) and opposite to the direction of the channel 31 from the closed end 312 to the open end 311, and in other embodiments, the direction of the channel 40 from the closed side 42 to the open side 41 is equal to the second direction and forms an angle, such as 90 degrees, 120 degrees, or 150 degrees, with the direction of the channel 31 from the closed end 312 to the open end 311.
In addition, as shown in fig. 4 to 7, in either the first embodiment or the second embodiment, the end portions between the side plates 60 of the second connector 5 are connected to each other to form a connection end 61, and the connection end 61 is provided with a guide portion 611. In this embodiment, the guiding portion 611 includes a cantilever fixed at the connecting end 61, the free end of the cantilever reciprocates along a first direction (i.e. the x-axis direction), and the protruding blocks 81 of the guiding portion 611 and the positioning portion 80 extend and protrude in a direction opposite to the first direction (i.e. the x-axis negative direction). In the present embodiment, when the first connector 1 is correspondingly assembled to the second connector 5, the guiding portion 611 is correspondingly accommodated in the guiding groove 40. Therefore, by the geometric fit between the guiding portion 611 of the second connecting member 5 and the guiding slot 40 of the first connecting member 1, the positioning effect is achieved during assembling, and during the rotation process of separating the two, the operating hand feeling can be provided by some micro resistance to remind the user of the rotating position, in some embodiments, the guiding portion 611 includes a compressible elastic member, the compressible elastic member moves back and forth along the first direction, in other embodiments, the protrusion 81 of the positioning portion 80 extends and protrudes opposite to the first direction, and the guiding portion 611 extends and protrudes opposite to the first direction.
As shown in fig. 1 and 15, the sliding groove 31 and the guiding groove 40 of the first connecting member 1 are located on the same plane on the combining member 30. In the present embodiment, the sliding groove 31 and the guiding groove 40 are located on the upper surface P1 of the combining element 30, in some embodiments, the sliding groove 31 and the guiding groove 40 of the first connecting element 1 are located on two opposite parallel surfaces on the combining element 30, for example, the sliding groove 31 is located on the upper surface P1 of the combining element 30 and the guiding groove 40 is located on the lower surface P2 of the combining element 30, in other embodiments, two guiding grooves 40 may be respectively located on the upper surface P1 and the lower surface P2.
Therefore, through the relative position setting of the guide groove 40 and the sliding groove 31 of the first connecting piece 1 and the guide part 611 of the second connecting piece 5, various design methods for restraining the first connecting piece 1 and the second connecting piece 5 are provided so as to meet the use requirements of different products.
As shown in fig. 4,5, 15 to 16, the guide portion 611 of the second connecting member 5 has an inclined surface 6111, and the inclined surface 6111 is away from the connecting end 61. In this embodiment, the inclined surface 6111 is a trapezoidal inclined surface and faces the movable end 821, and in some embodiments, the inclined surface 6111 is a triangular inclined surface, a quadrangular inclined surface, other polygonal inclined surfaces, or the like. Thereby, the inclined surface 6111 of the guiding part 611 of the second connecting piece 5 is matched with the guiding groove 40 of the first connecting piece 1 in a geometric way, so that the two parts are assembled smoothly and achieve a positioning effect, and in addition, the two parts are separated and rotated in a smooth movement way in the rotating process.

In this embodiment, the linear distance L5 between the first side portion 43 and the second side portion 44 decreases linearly to the groove bottom 45, for example, on the upper surface P1, the linear distance L51 between the first side portion 43 and the second side portion 44 on the peripheral side edge of the coupling member 30 is greater than the linear distance L52 between the first side portion 43 and the second side portion 44 on the groove bottom 45, and in other embodiments, the contour between the first side portion 43 and the second side portion 44 is arc-shaped, and the distance between each other decreases gradually toward the groove bottom 45, so that the guide groove 40 guiding the first coupling member 1 smoothly leaves the guide portion 611 of the second coupling member 5 through the above-mentioned geometric design of the guide groove 40 during the rotation of the first coupling member 1, so as to reduce the resistance generated during the rotation and increase the product yield.
As shown in fig. 1 and 2, the distance L6 between the first side 43 and the second side 44 of the guide groove 40 gradually increases from the closed side 42 to the open side 41. In the present embodiment, the distance L6 between the first side portion 43 and the second side portion 44 increases linearly from the closed side 42 to the open side 41, for example, on the upper surface P1, the distance L61 between the first side portion 43 and the second side portion 44 at the closed side 42 is smaller than the distance L62 between the first side portion 43 and the second side portion 44 at the open side 41. In other embodiments, the profile of the closed side 42 and the first side 43 is arc-shaped or other geometric shapes, so that, in the process of assembling the first connector 1 along the second direction to the second connector 5, the opening side 41 with a relatively wide width (i.e. the distance between the first side 43 and the second side 44) of the guide slot 40 of the connector 30 of the first connector 1 will first contact the positioning portion 80, and then the width is gradually narrowed, so that the positioning portion 80 can be guided to gradually displace and deform and move along the first direction, so as to reduce the assembling resistance and increase the product quality.
In summary, in the connecting piece provided by the embodiment of the invention, the positioning portion is prevented from being deformed in a rotation withdrawing manner in a separation process, so that the probability of permanent deformation of the positioning portion is reduced, and the product quality is improved and the service life is prolonged.
