The spring clip elbows 23 on both sides of the pin 11 may limit the pin 11, and the electrical connection between the pin 11 and the spring clip 2 is more reliable.

[0031] In one embodiment, reference Figure 1-12 The spring piece 2 has a first through hole 24, at least part of the spring piece main body 21 is located on the circumferential side of the corresponding first through hole 24, one pin 11 corresponds to one spring piece 2, one pin 11 corresponds to one first through hole 24, at least part of the spring piece main body 21 extends along the extension direction of the pin 11, the spring piece main body 21 has a first end 211 and a second end 212 arranged along the length extension direction of the spring piece main body 21, the first end 211 is a part of the wall forming the first through hole 24, the second end 212 is located outside the first through hole 24, at least part of the corresponding wall of the spring piece main body 21 is stacked, the stacked part includes at least the second end 212 and the stacked part of the first end 211.

[0032] It should be noted that: the elastic sheet is bent to form a spring sheet, and the length extension direction of the spring sheet main body 21 refers to the length direction of the elastic sheet before being bent.

[0033] In such an integrated component, the spring piece 2 has a first through hole 24, at least a portion of the spring piece main body 21 is located on the circumferential side of the corresponding first through hole 24, the spring piece main body 21 has a first end 211 and a second end 212 arranged along the length extension direction of the spring piece main body 21, the first end 211 is a portion of the wall forming the first through hole 24, the second end 212 is located outside the first through hole 24, at least a portion of the corresponding wall portion of the spring piece main body 21 is stacked, the stacked portion includes at least the second end 212, and the stacked portion includes at least the first end 211, so that the stacked portion can limit the inner wall portion.

[0034] Specifically, refer to Figure 2-Figure 6The cross section of the spring body 21 in the corresponding extension direction of the pin 11 is at least partially or substantially rectangular. The spring body 21 includes a first wall 213, a second wall 214, a third wall 215, a fourth wall 216 and a fifth wall 217. The first wall 213 and the third wall 215 are arranged opposite to each other, and the second wall 214 and the fourth wall 216 are arranged opposite to each other. One of the first wall 213, the second wall 214, the third wall 215 and the fourth wall 216 is adjacent to the fifth wall 217. 7 is stacked, at least part of the fifth wall portion 217 is located outside the first through hole 24, the first wall portion 213, the second wall portion 214, the third wall portion 215 and the fourth wall portion 216 form at least a part of the wall portion of the first through hole 24, one spring piece 2 includes at least two spring piece bending portions 22 and two spring piece elbows 23, at least two spring piece elbows 23 are arranged opposite to each other and are located on both sides of at least part of the corresponding pin 11, and at least one of the two spring piece bending portions 22 extends integrally from the fifth wall portion 217.

[0035] Such an integrated component is stacked with the fifth wall 217 through the first wall 213, the second wall 214, the third wall 215 and one of the fourth wall 216, at least part of the fifth wall 217 is located outside the first through hole 24, at least two spring leaf elbows 23 are arranged opposite to each other and are located on both sides of at least part of the corresponding pin 11, at least one of the two spring leaf bent portions 22 extends integrally from the fifth wall 217, when the pin 11 and the two spring leaf elbows 23 are in contact, the pin 11 applies forces in opposite directions to the two spring leaf elbows 23, so that the two spring leaf elbows 23 are deformed to the two sides of the pin 11 or have a tendency to deform to the two sides of the pin 11; for example, the first wall 213 to the fifth wall 217 are arranged along the pin 11 corresponding to the spring leaf 2 The cross-sections in the extension direction are spirally arranged in sequence, that is, the first wall portion 213 and the fifth wall portion 217 are stacked, at least one of the two spring sheet bending portions 22 is integrally extended from the fifth wall portion 217, and the two spring sheet elbows 23 are arranged opposite to each other, that is, the other spring sheet bending portion 22 is integrally extended from the third wall portion 215, the two spring sheet elbows 23 and the plug pin 11 are abutted, and the two spring sheet elbows 23 are respectively subjected to the force from the plug pin 11 toward the fifth wall portion 217 and the third wall portion 215, and indirectly, the fifth wall portion 217 and the third wall portion 215 are respectively subjected to the extrusion force away from the first through hole 24. At this time, the second wall portion 214 and the fourth wall portion 216 cause the third wall portion 215 to be subjected to the pulling force toward the first through hole 24, which can avoid or reduce the possibility of deformation of the third wall portion 215.

[0036] More specifically, refer to Figure 2-Figure 6A spring piece 2 has at least one pin 25, and the pin 25 is welded and fixed to the circuit board 3. A spring piece 2 includes at least two spring piece bending parts 22. Along the extension direction of the spring piece 2 corresponding to the pin 11, at least one spring piece bending part 22 and at least one pin 25 are located on the wall corresponding to the spring piece main body 21 outside the first through hole 24.

[0037] Such an integrated component is located on the wall corresponding to the spring sheet main body 21 outside the first through hole 24 through at least one spring sheet bending portion 22 and at least one pin 25, and the pin 25 is welded and fixed to the circuit board 3, that is, the circuit board 3 can limit the wall corresponding to the spring sheet main body 21 outside the first through hole 24, so that the structure of the spring sheet 2 is more reliable; in this embodiment, a spring sheet bending portion 22 and at least one pin 25 are located on the fifth wall portion 217, and the circuit board 3 limits the fifth wall portion 217, thereby reducing the deformation of the spring sheet 2 caused by the force of the pin 11 on the spring sheet elbow 23 corresponding to the fifth wall portion 217, thereby enhancing the reliability of the spring sheet 2.

[0038] Of course, in this embodiment (not shown in the figure), the spring piece 2 can also be limited by adding a limiting portion on the spring piece main body 21 and / or the spring piece bending portion 22 corresponding to the spring piece 2, so as to maintain the stability of the structure. For example, the spring piece 2 is used as an insert, and a plastic with less elasticity than the metal spring piece 2 is provided on the spring piece main body 21 and / or the spring piece bending portion 22 to limit the spring piece 2 or has a tendency to limit the spring piece 2, such as nylon plus glass fiber.

[0039] More specifically, refer to Figure 2-Figure 3 , at least part of the spring clip elbow 23 is located in the first through hole 24.

The wall corresponding to the spring clip body 21 is subjected to the action of the adjacent wall, and the action force is opposite to the action force from the plug pin 11. Of course, the wall corresponding to the spring clip body 21 can also be limited or fixed to the circuit board 3. The circuit board 3 limits the spring clip body 21, and the structure is more stable. For example, in other embodiments, refer to Figure 6 At least part of the spring clip elbow 23 is located outside the first through hole 24, the pin 11 has a force on the spring clip elbow 23, and at least part of the spring clip elbow 23 is located outside the first through hole 24, resulting in the force point / line / surface of the pin 11 on the spring clip elbow 23 being at least partly located outside the first through hole 24, and the spring clip body 21 can indirectly act on the spring clip elbow 23 with a small reverse force, the spring clip bending portion 22 and the spring clip body 21 are easily bent, deformed or broken, and the structure is unreliable.

[0040] Of course, in another embodiment, in order to increase the contact area between the pin 11 and the spring 2, the cross-sectional area of ​​the pin 11 may be rectangular, and the contact area is increased, so that a large current connection can be achieved.

[0041] In addition, in the present embodiment, at least part of the cross-section of the spring body 21 in the extension direction of the corresponding pin 11 is rectangular or approximately rectangular, and one spring 2 may include four spring bending portions 22 and four spring elbows 23, and the four spring bending portions 22 respectively correspond to the wall portions on the peripheral side of the spring body 21 with a rectangular or approximately rectangular cross-section; specifically, the first wall portion 213, the second wall portion 214, the third wall portion 215, the fourth wall portion 216 and the fifth wall portion 217 corresponding to the spring body 21 are arranged adjacent to each other in sequence, the fifth wall portion 217 and the first wall portion 213 are stacked, and at least part of the fifth wall portion 217 is located outside the first through hole 24, and the four spring bending portions 222 extend integrally from the second wall portion 214, the third wall portion 215, the fourth wall portion 216 and the fifth wall portion 217 respectively, and one pin 11 corresponds to four spring elbows 23, so the structure is more stable.

[0042] Of course, the cross-sectional shape of the spring body 21 in the corresponding extending direction of the plug pin 11 may be different.

That is, one pin 11 corresponds to three spring elbows 23, and the three spring elbows 23 are located on the peripheral side of one pin 11, forming a triangular stable structure, and the spring clip 2 structure is more stable.

Along the extension direction of the pin 11, the projection area of ​​the pin body 111 is located in the second through hole 31, and there is space in the extension direction of the pin 11. The space can compensate for the deviation of the pin 11 and the spring piece 2 in the extension direction of the pin 11 caused by the assembly gap.
