[0057] See also Figure 4 and Figure 5 Optionally, on the basis of the technical solution of the above embodiment, the first clamping slot 14 further includes a fifth clamping point 141; the clamping point at the bottom of the first clamping slot 14 away from the first electrical connection part 12 is the fifth clamping point 141; the first clamping point 140 and the fifth clamping point 141 are arranged at intervals along the direction in which the first flexible portion 11 points to the first electrical connection part 12; the second clamping slot 15 further includes a sixth clamping point 151; the clamping point at the bottom of the second clamping slot 15 away from the first electrical connection part 12 is the sixth clamping point 151; the second clamping point 150 and the sixth clamping point 151 are arranged at intervals along the direction in which the first flexible portion 11 points to the first electrical connection part 12; the first clamping slot 14 is a rectangular clamping slot; the second clamping slot 15 is a rectangular clamping slot; the shapes of the first clamping covering portion, the second clamping covering portion and the third clamping slot are all rectangular.

Figure 5 The shapes of the first clamping position covering portion 25 and the second clamping position covering portion 26 are both set to be rectangular, such as Figure 6 As shown, when connected, the first clamping groove 14 is clamped with the first clamping covering part 25, and the second clamping groove 15 is clamped with the second clamping covering part 26, so that the first electrical connection part 12 and the second electrical connection part 22 are located in correspondence, and the connection of the first electrical connection part 12 and the second electrical connection part 22 is completed by pressure. This arrangement reduces the difficulty of connecting the first electrical connection part 12 and the second electrical connection part 22 and improves the connection efficiency.

[0059] See also Figure 1-Figure 2 and Figure 4-Figure 5 Optionally, on the basis of the technical solution of the above embodiment, the distance L between the first card point 140 and the first electrical connection part 12 along the direction from the first flexible portion 11 to the first electrical connection part 12 is equal to the distance L1 between the third card point 240 and the second electrical connection part 22 along the direction from the second flexible portion 21 to the second electrical connection part 22; the distance L between the second card point 150 and the first electrical connection part 12 along the direction from the first flexible portion 11 to the first electrical connection part 12 is equal to the distance L1 between the fourth card point 241 and the second electrical connection part 22 along the direction from the second flexible portion 21 to the second electrical connection part 22.

[0060] In the embodiment of the present invention, by setting the first card point 140 along the direction of the first flexible portion 11 pointing to the first electrical connection portion 12 to be equal to the distance L from the first electrical connection portion 12, and the third card point 240 along the direction of the second flexible portion 21 pointing to the second electrical connection portion 22 to be equal to the distance L1 from the second electrical connection portion 22, the second card point 150 along the direction of the first flexible portion 11 pointing to the first electrical connection portion 12 to be equal to the distance L from the first electrical connection portion 12, and the fourth card point 241 along the direction of the second flexible portion 21 pointing to the second electrical connection portion 22 to be equal to the distance L1 from the second electrical connection portion 22, the first electrical connection portion 12 is achieved to correspond to the second electrical connection portion 22, and the connection between the first electrical connection portion 12 and the second electrical connection portion 22 is facilitated.

[0061] Continue to see Figure 1-Figure 2 and Figure 4-Figure 5 Optionally, based on the technical solution of the above embodiment, the first card point 140 is spaced apart from the second card point 150 by a first preset dimension a along a direction perpendicular to the first flexible portion 11 pointing to the first electrical connection portion 12; the third card point 240 is spaced apart from the fourth card point 241 by a first preset dimension a along a direction perpendicular to the second flexible portion 21 pointing to the second electrical connection portion 22.

[0062] Wherein, the first preset size a is greater than or equal to 8.0 mm and less than or equal to 9.0 mm,

[0063] Specifically, when the first preset dimension a is less than 8.0 mm, the distance between the first clamping point 140 and the second clamping point 150 becomes smaller. Since there is a large extrusion pressure at the position where the first clamping point 140 and the third clamping point 240 are clamped and at the position where the second clamping point 150 and the fourth clamping point 241 are clamped, the male flexible printed circuit board or the female flexible printed circuit board is damaged or broken. When the first preset value a is greater than 9.0 mm, the first clamping slot 14 and the second clamping slot 15 are too small, and the first clamping slot 14 and the second clamping slot 15 cannot be clamped with the third clamping slot 24, resulting in the male flexible printed circuit board and the female flexible printed circuit board falling off. Therefore, when the first preset dimension a is greater than or equal to 8.0 mm and less than or equal to 9.0 mm, not only can the male flexible printed circuit board or the female flexible printed circuit board be prevented from being damaged or broken, but the first clamping slot 14 and the second clamping slot 15 can also be clamped with the third clamping slot 24.

[0064] Continue to see Figure 1-Figure 2 and Figure 4-Figure 5 Optionally, based on the technical solution of the above embodiment, the first clamping covering portion 25 is spaced from the second clamping covering portion 26 by a second preset size b along a direction perpendicular to the second flexible portion 21 and pointing to the second electrical connecting portion 22;

[0065] The second preset size b is greater than or equal to the third preset value and smaller than the first preset size a; the third preset value is the first preset size a minus 0.5 mm.

[0066] Specifically, when the second preset dimension b is smaller than the third preset value, it is necessary to increase the pressure to make the male flexible printed circuit board deform greatly, which makes it difficult to press fit. When the second preset dimension b is greater than or equal to the first preset dimension a, the first clamping point 140 and the third clamping point 240 as well as the second clamping point 150 and the fourth clamping point 241 cannot be clamped, causing the male flexible printed circuit board to fall off from the female flexible printed circuit board. Therefore, the second preset dimension b is greater than or equal to the third preset value and smaller than the first preset dimension a, which can not only reduce the pressure, but also make the first clamping point 140 and the third clamping point 240 as well as the second clamping point 150 and the fourth clamping point 241 clamped.

[0067] See also Figure 4 and Figure 5Optionally, based on the technical solution of the above embodiment, the distance c between the first clamping point 140 and the fifth clamping point 141 along the direction from the first flexible portion 11 to the first electrical connection portion 12 is equal to the distance d between the first clamping covering portion 25 along the direction from the second flexible portion 21 to the second electrical connection portion 22; the distance c between the second clamping point 150 and the sixth clamping point 151 along the direction from the first flexible portion 11 to the first electrical connection portion 12 is equal to the distance d between the second clamping covering portion 26 along the direction from the second flexible portion 21 to the second electrical connection portion 22.

[0068] In the embodiment of the utility model, by setting the distance c between the first clamping point 140 and the fifth clamping point 141 along the direction of the first flexible portion 11 pointing to the first electrical connection portion 12 and the distance d between the first clamping covering portion 25 along the direction of the second flexible portion 21 pointing to the second electrical connection portion 22 to be equal, and the distance c between the second clamping point 150 and the sixth clamping point 151 along the direction of the first flexible portion 11 pointing to the first electrical connection portion 12 and the distance d between the second clamping covering portion 26 along the direction of the second flexible portion 21 pointing to the second electrical connection portion 22 to be equal, the first clamping groove 14 is clamped with the first covering portion, and the second clamping groove 15 is clamped with the second covering portion, thereby completing the lateral positioning and longitudinal positioning of the first electrical connection portion 12 and the second electrical connection portion 22, reducing the difficulty in connecting the first electrical connection portion 12 and the second electrical connection portion 22, and increasing the connection efficiency.

[0069] See also Figure 3 and Figure 4 Optionally, based on the technical solution of the above embodiment, the distance c between the first card point 140 and the fifth card point 141 along the direction from the first flexible portion 11 to the first electrical connection portion 12, and the distance c between the second card point 150 and the sixth card point 151 along the direction from the first flexible portion 11 to the first electrical connection portion 12 are both greater than or equal to 3 mm and less than or equal to 5 mm.

[0070] Specifically, when the distance c between the first clamping point 140 and the fifth clamping point 141 along the direction from the first flexible portion 11 to the first electrical connection portion 12, and the distance c between the second clamping point 150 and the sixth clamping point 151 along the direction from the first flexible portion 11 to the first electrical connection portion 12 are less than 3 mm, since the first clamping groove 14, the first clamping groove 14 and the third clamping groove 24 are too small, the first clamping point 140 and the third clamping point 240, and the second clamping point 150 and the fourth clamping point 241 are not firmly clamped. When the distance c between the first clamping point 140 and the fifth clamping point 141 along the direction from the first flexible portion 11 to the first electrical connection portion 12, and the distance c between the second clamping point 150 and the sixth clamping point 151 along the direction from the first flexible portion 11 to the first electrical connection portion 12 are greater than 5 mm, the first clamping groove 14, the second clamping groove 15 and the third clamping groove 24 are too large, thereby wasting materials.

[0072] In the embodiment of the utility model, the hardness of the first electrical connection part 12 and the second electrical connection part 22 is enhanced by providing a reinforcing steel plate, thereby facilitating the connection between the first electrical connection part 12 and the second electrical connection part 22 .
