Fig. 1 is a first angular schematic view of a metal dome 100, fig. 2 is a second angular schematic view of the metal dome 100 in fig. 1, and fig. 3 is a third angular schematic view of the metal dome 100 in fig. 1 according to an exemplary embodiment. As shown in fig. 1-3, the metal spring 100 may include a base plate 1, a side arm 2, a welding plate 3, a spring arm 4, and a spring head 5, where the side arm 2 and the spring arm 4 are connected to edges of the base plate 1, and in particular, as provided in the disclosure, the side arm 2 and the spring arm 4 may be connected to a set of adjacent edges of the base plate 1, and in other embodiments, the side arm 2 and the spring arm 4 may be connected to a set of opposite edges of the base plate 1, or the side arm 2 and the spring arm 4 may be connected to the same edge of the base plate 1, which is not limited in this disclosure.
The welding plate 3 is connected with the edge of the side arm 2 far away from the bottom plate 1, and the welding plate 3 extends outwards relative to the bottom plate 1, and as a certain height exists in the side arm 2, the height can be set at intervals between the welding plate 3 and the bottom plate 1 in the thickness direction of the bottom plate 1, and the welding plate 3 can be used for welding and fixing the circuit board provided with the metal elastic sheet 100. The spring arm 4 and the welding plate 3 are both located on the same side of the bottom plate 1, such as shown in fig. 1, the spring arm 4 and the welding plate 3 are both located above the bottom plate 1, the spring head 5 is arranged on the spring arm 4, and after the subsequent spring head 5 is pressed, the circuit board and other components or circuit boards of the metal spring 100 can be conducted through the metal spring 100.
In this embodiment, the soldering board 3 soldered to the circuit board is located above the base board 1, so when the metal spring sheet 100 is assembled on the circuit board afterwards, an opening 101 may be formed on the circuit board as shown in fig. 4, the base board 1 of the metal spring sheet 100 may be sunk in the opening 101, and the soldering board 3 is soldered to the circuit board. Therefore, compared with the scheme of assembling the metal spring plate 100 on the surface of the circuit board, the height of the metal spring plate 100 protruding out of the circuit board is reduced, so that the internal space of the electronic equipment is saved. Wherein, the bottom plate 1 is sunk into the opening 101, which means that the bottom plate 1 is positioned in the opening 101; alternatively, the base plate 1 is located outside the opening 101 through the opening 101, which is not limited by the present disclosure.
In this embodiment, the spring arm 4 may include a connecting arm 41, a bent arm 42 and a first inclined arm 43, where the connecting arm 41 is connected to an edge of the base plate 1, such as shown in fig. 1-3, the connecting arm 41 is connected to one side edge of the base plate 1, and the side arm 2 is connected to an adjacent other side edge. The connecting arm 41 may be arranged in an arc-shaped folded shape after extending in a direction away from the bottom plate 1, the bending arm 42 is connected with the edge of the connecting arm 41 away from the bottom plate 1, in the thickness direction of the bottom plate 1, the first end of the bending arm 42 connected with the connecting arm 41 is away from the bottom plate 1 and protrudes upwards, as shown in fig. 2, the left part of the bending arm 42 is protruding upwards, the end of the bending arm 42 away from the connecting arm 41 is protruding towards the bottom plate 1, as shown in fig. 2, the right part of the bending arm 42 is protruding downwards, and the first end and the second end are in smooth transition, at this time, the bending arm 42 is basically arranged in an S shape, so that the length of the bending arm 42 can be increased, the yield of the bending arm 42 is reduced, and smooth bouncing of the bending arm 4 after pressing the bending arm 4 for several times is facilitated. The first inclined arm 43 may be connected to an edge of the bending arm 42 facing away from the connecting arm 41, and the first inclined arm 43 may extend obliquely upward with respect to the bending arm 42, and the warhead 5 may be disposed on the first inclined arm 43, and then the first inclined arm 43 may receive a main force when the metal spring 100 is pressed.
Further, still as shown in fig. 2, in the thickness direction of the base plate 1, i.e., in the vertical direction in fig. 2, the maximum height of the bending arm 42 is lower than the maximum height of the welding plate 3, i.e., H1 < H2 in fig. 2 so that when the metal shell fragment 100 is pressed later, excessive pressure can be borne by the welding plate 3 first, the pressure borne by the bending arm 42 is reduced, and the damage probability of the bending arm 42 is reduced. Wherein the maximum height of the bending arm 42 is understood as the distance between the plane tangential to the arc of the S-shaped bending arm 42 away from the base plate 1 and the base plate 1, the maximum height of the welding plate 3 is understood as the distance between the surface of the welding plate 3 facing away from the base plate 1 and the base plate 1,
taking the embodiment provided in the present disclosure as an example, a set of opposite edges of the base plate 1 are respectively connected with the side arms 2, and an edge of each side arm 2 facing away from the base plate 1 may be connected with a welding plate 3, that is, in the embodiment provided in the present disclosure, the metal spring plate 100 may include two side arms 2 and two welding plates 3, so that when the subsequent metal spring plate 100 is welded to a circuit board through the welding plates 3, the contact area may be increased through the two welding plates 3, and the stress of the circuit board may be reduced to protect the circuit board. In the embodiment provided in the present disclosure, the side arm 2 and the spring arm 4 may be connected to a set of adjacent side edges of the base plate 1, for example, the side arm 2 and the connecting arm 41 are connected to adjacent edges of the base plate 1, so that, on one hand, the center of gravity position of the metal spring 100 may be optimized, and the deflection of the metal spring 100 may be reduced, and on the other hand, the limitation of the side arm 2 on the free extension of the spring arm 4 may be reduced. Of course, in other embodiments, the arm 4 and the side arm 2 may be attached to the same side edge or opposite side edges of the base plate 1, which is not limited by the present disclosure.
Further, the latch arm 4 may further include a second inclined arm 44, where the second inclined arm 44 is connected to the first inclined arm 43, the second inclined arm 44 extends obliquely downward toward the base plate 1 relative to the first inclined arm 43, and the side arm 2 may include a limiting portion 21, where the limiting portion 21 may be matched with an end portion of the second inclined arm 44 facing away from the first inclined arm 43 to limit, so that when the latch arm 4 is stressed, the end portion of the second inclined arm 44 can only move in an area defined by the limiting portion 21, thereby limiting the movement of the latch arm 4, reducing rollover or displacement of the metal spring 100, and reducing the probability of scratching the latch head 5.
In the embodiment provided in the present disclosure, the limiting portion 21 may include a limiting opening, and the end of the second diagonal arm 44 facing the base plate 1 may extend outward to form a stepped portion with the other end, so that the end of the second diagonal arm 44 may extend into the limiting opening, and the movement of the second diagonal arm 44 is limited by the shape of the limiting opening. The shape of the limiting vent can be designed as desired, which is not limited by the present disclosure. In other embodiments, the limiting portion 21 may also include a limiting groove, and the end portion of the second inclined arm 44 may also extend into the limiting groove, so as to limit the movement of the second inclined arm 44 through the limiting groove. Meanwhile, the side arm 2 is provided with a limit through hole or a limit groove, so that the weight of the metal spring 100 can be reduced, and the bearing acting force of the subsequent assembly with the metal spring can be reduced. Of course, in order to reduce the force applied to the circuit board, the base plate 1 may also include a weight-reducing groove or a weight-reducing through groove, which is not limited by the present disclosure.
In the various embodiments described above, the edge of the soldering plate 3 facing away from the side arm 2 may comprise at least one arcuate region 31, so as to increase the edge length of the side of the soldering plate 3, and subsequently, when soldering the soldering plate 3 and the circuit board, the solder paste laying area may be increased, so as to facilitate an increase in the connection strength between the soldering plate 3 and the circuit board. As in the embodiments of the present disclosure, each welding plate 3 may be provided with only a single arc-shaped region, or, in other embodiments, each welding plate 3 may be provided with a plurality of arc-shaped regions, which may be specifically designed as needed, and the present disclosure is not limited thereto.
