[0028] The utility model provides a connecting piece to connect the two spring pieces, and the connecting piece can simultaneously apply force to the two spring pieces, so that the two spring pieces are deformed at the same time, thereby realizing that the two spring pieces are locked or unlocked in the slot at the same time.

[0029] Embodiment 1

[0030] like Figures 1 to 4 As shown, this embodiment provides a connection structure 100, characterized in that it includes: a base 110, a top surface of the base 110 is provided with a socket 111 for inserting a PCB board, and a side surface of the base 110 is provided with two parallel card slots 112; and

[0031] The elastic member 120 includes two spring sheets 121 and a connecting sheet 122 connecting the two spring sheets 121 . The spring sheets 121 can be clamped in the clamping slot 112 . A reinforcing flange 123 extends from the connecting sheet 122 , and the reinforcing flange 123 is bent toward the connecting sheet 122 .

[0032] A PCB board socket 111 is provided on the top surface of the base 110 , and terminals of an electrical connector are built into the PCB board socket 111 . When the PCB board contacts the terminals, the PCB board is connected to the circuit to realize the preset functions in the PCB board.

[0033] The elastic member 120 includes two spring pieces 121 and a connecting piece 122 connecting the spring pieces 121. Two slots 112 are arranged in parallel on the side of the base 110, and the spring pieces 121 can be arranged in the slots 112. It is necessary to realize that the two spring pieces 121 are locked or unlocked in the slots 112 at the same time, and the connecting piece 122 is arranged to connect the two spring pieces 121. When a force is applied to the connecting piece 122, the connecting piece 122 transmits the force to the two spring pieces 121 at the same time, causing the two spring pieces 121 to deform at the same time, thereby realizing that the two spring pieces 121 are locked or unlocked in the slots 112 at the same time. And because a force is applied to the connecting piece 122, if the strength of the connecting piece 122 is too low, it is easy to cause the connecting piece 122 to break. A reinforcing flange 123 is extended from the connecting piece 122 to strengthen the convenience of bending in the direction of the connecting piece 122. The setting of the reinforcing flange 123 helps to enhance the load capacity of the connecting piece 122 and increase the strength of the connecting piece 122.

[0034] In this embodiment, since the connecting piece 122 is provided to connect the two spring pieces 121, the connecting piece 122 can simultaneously apply force to the two spring pieces 121, so that the two spring pieces 121 are deformed at the same time, thereby realizing that the two spring pieces 121 are simultaneously locked or unlocked in the slot 112. In addition, the reinforcing flange 123 is provided on the connecting piece 122, which helps to enhance the load capacity of the connecting piece 122, increase the strength of the connecting piece 122, and facilitate the connecting piece 122 to better apply force to the two spring pieces 121.

[0035] Embodiment 2

[0036] like Figure 3 As shown, based on the first embodiment, the reinforcing flange 123 is bent and fitted with the connecting piece 122 .

[0037] In this embodiment, the reinforcing flange 123 is folded 180°, which is equivalent to increasing the thickness of the connecting piece 122, and better increasing the strength of the connecting piece 122. Compared with using thicker materials, the scheme of this embodiment uses thin materials, which is cheaper. Compared with increasing the thickness by stack welding, the scheme of this embodiment has a simpler process, which can shorten the processing time and save processing costs.

[0038] In one embodiment, the connecting piece 122 has a lightening hole 124, and the lightening hole 124 passes through the corresponding reinforcing flange 123. The lightening hole 124 can reduce the weight of the connecting piece 122, but will not adversely affect the strength of the connecting piece 122.

[0039] Embodiment 3

[0040] like Figure 4As shown, based on the first embodiment, the spring piece 121 includes an elastic upper piece 1211, an elastic lower piece 1212 and a deformation portion 1213. The deformation portion 1213 is an arc-shaped thin-walled part, and the two ends of the deformation portion 1213 are respectively connected to the elastic upper piece 1211 and the elastic lower piece 1212.

[0041] In this embodiment, the deformation part 1213 is an arc-shaped thin-walled part. When subjected to external force, the thin-walled part is deformed and the arc size changes. The two ends of the deformation part 1213 are respectively connected to the elastic upper piece 1211 and the elastic lower piece 1212. When the elastic upper piece 1211 and / or the elastic lower piece 1212 are subjected to external force, the force is transmitted to the deformation part 1213 via the elastic upper piece 1211 and / or the elastic lower piece 1212, and the deformation part 1213 is deformed and drives the elastic upper piece 1211 and the elastic lower piece 1212 connected to the deformation part 1213 to change their positions, so that the distance between the elastic upper piece 1211 and the elastic lower piece 1212 changes.

[0042] The depth of the slot 112 on the base 110 is a fixed value. First, a force is applied to the spring sheet 121 to reduce the distance between the elastic upper sheet 1211 and the elastic lower sheet 1212. The spring sheet 121 is placed in the slot 112. After the external force is removed, the spring sheet 121 is locked in the slot 112. When the spring sheet 121 is taken out for medicine removal, a force is applied to the spring sheet 121 to reduce the distance between the elastic upper sheet 1211 and the elastic lower sheet 1212, and the spring sheet 121 is taken out from the slot 112.

[0043] In one embodiment, the spring sheet 121 includes an elastic upper sheet 1211, an elastic lower sheet 1212 and a deformable portion 1213 as an integrated structure. Specifically, the elastic upper sheet 1211, the elastic lower sheet 1212 and the deformable portion 1213 are formed by bending a thin-walled material, and the specific bending angle is set according to the depth adaptability of the card slot 112.

[0044] In one embodiment, the spring sheet 121 further includes a connecting portion 1214, one end of the connecting portion 1214 is connected to the elastic upper sheet 1211, and the other end of the connecting portion 1214 is connected to the connecting sheet 122. The spring sheet 121 is connected to the connecting sheet 122 through the connecting portion 1214. When force is applied to the connecting sheet 122, the force received by the connecting sheet 122 is transmitted to the elastic upper sheet 1211 through the connecting portion 1214, and the elastic upper sheet 1211 approaches the elastic lower sheet 1212, and the distance between the elastic upper sheet 1211 and the elastic lower sheet 1212 is reduced.

[0045] Furthermore, the other end of the connection part 1214 is welded to the connection sheet 122. The welding is firm to prevent the connection part 1214 and the connection sheet 122 from falling off. The connection part 1214 can be specifically formed by extending the elastic upper sheet 1211, and there is no connection gap between the connection part 1214 and the elastic upper sheet 1211 to avoid stress concentration.

[0048] The beneficial effects of the electrical connector of this embodiment are equivalent to the beneficial effects of the above-mentioned connection structure 100, and will not be described in detail here.
