Description

Technical Field

[0001] This utility model relates to the field of elastic connector technology, and in particular to a spring, connector and electronic device. Background Technology

[0002] In connectors, male and female terminal blocks are typically mated together for connection. To improve the strength of the connection between the male and female terminal blocks, connectors are usually equipped with spring clips. During insertion, the male terminal block will squeeze the spring clips, thereby providing the spring clips to provide the elastic force to keep the male terminal block in close contact with the female terminal block.

[0003] In related technologies, the springs in connectors are generally crown springs. The elastic ribs in the crown springs can provide elastic force to keep the male terminal block abutting against the female terminal block after deformation.

[0004] However, the elastic ribs in the crown spring are prone to breakage under frequent insertion and removal of the male and female terminal blocks, which can lead to connector damage. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art.

The second aspect of this invention also provides a connector. The third aspect of this invention also provides an electronic device.

[0006] According to the first aspect of the present invention, the spring includes an extension, a deformable portion, and a tentacle; two extensions are provided, which are arranged side by side on a preset plane; the deformable portion is located between the two extensions, and the deformable portion includes a deformable segment and two connecting segments, the two opposite ends of the deformable segment are respectively connected to the two extensions through the two connecting segments, the connecting segments are inclined at a first included angle relative to the preset plane, and the deformable segment is inclined at a second included angle relative to the preset plane; at least one tentacle is provided at the opposite ends of the two extensions, and the tentacle is inclined at a third included angle relative to the preset plane.

[0007] The spring sheet described in this utility model has at least the following beneficial effects: When the spring sheet of this application is used, each of the spring sheet's contact points can abut against the bearing surface. After the deformable part is subjected to downward pressure, the deformable section is inclined at a second included angle relative to the preset plane, allowing the deformable section to deform and store a certain amount of elastic potential energy. Similarly, the connecting section is inclined at a first included angle relative to the preset plane, allowing the connecting section to deform and store a certain amount of elastic potential energy. Furthermore, the contact points are inclined at a third included angle relative to the preset plane, allowing the contact points to deform and store a certain amount of elastic potential energy. Moreover, in the spring sheet of this utility model, the deformable section, connecting section, and contact points can all provide a certain amount of elastic support. When one or two of the deformable section, connecting section, and contact points fail, the remaining two or one can still continue to work, giving the spring sheet of this utility model a longer service life. When the spring sheet of this utility model is applied to a connector, under the condition of frequent insertion and removal of male and female terminal blocks, the spring sheet of this embodiment still has a longer service life.

[0008] According to the spring sheet described in the embodiment of this utility model, the angle α of the first included angle satisfies: 10°≤α≤30°, the angle β of the second included angle satisfies: 35°≤β≤40°, and the angle γ of the third included angle satisfies: 20°≤γ≤30°.

In the same deformation segment, the end of the first deformation area away from the second deformation area is connected to one of the connecting segments, and the end of the third deformation area away from the second deformation area is connected to another connecting segment. The second deformation area is located on the same side as the two connecting segments. The first deformation area, the second deformation area, and the third deformation area together define a groove, and the second deformation area forms a protrusion.

[0030] The following is for reference. Figures 1 to 3 The spring clip of the first aspect of this utility model will be described in detail.

[0031] refer to Figures 1 to 3 According to a first aspect embodiment of the present invention, the spring includes an extension 100, a deformable portion 200, and a tentacle 300. Two extensions 100 are provided, and the two extensions 100 are arranged side by side on a preset plane. The deformable portion 200 is disposed between the two extensions 100, and the deformable portion 200 includes a deformable segment 210 and two connecting segments 220. The two opposite ends of the deformable segment 210 are respectively connected to the two extensions 100 through the two connecting segments 220. The connecting segments 220 are inclined at a first included angle relative to the preset plane, and the deformable segment 210 is inclined at a second included angle relative to the preset plane. At least one tentacle 300 is provided at the opposite ends of the two extensions 100, and the tentacle 300 is inclined at a third included angle relative to the preset plane.

[0032] For example, such as Figures 1 to 3As shown, the spring includes an extension 100, a deformable portion 200, and a tentacle 300. Two extensions 100 are provided, arranged side-by-side in the left-right direction, and both extensions 100 extend in the front-back direction. The preset plane containing the two extensions 100 is a horizontal plane. The deformable portion 200 extends in the left-right direction and includes a deformable section 210 and two connecting sections 220. The two connecting sections 220 are connected to the left and right ends of the deformable section 210, respectively, and are also connected to the two extensions 100. The connecting section on the left side... Segment 220 is inclined at the upper right to form a first angle with the horizontal plane. The connecting segment 220 on the right side is inclined at the upper left to form a first angle with the horizontal plane. The deformable part 200 is inclined at the upper front to form a second angle with the horizontal plane. Each of the two extensions 100 has an antenna 300 at one of its opposite ends. The antenna 300 on the left extension 100 is inclined at the lower left to form a third angle with the horizontal plane. The antenna 300 on the right extension 100 is inclined at the lower right to form a third angle with the horizontal plane.

[0033] It is understood that, in use, each of the spring clips 300 of this invention can abut against the bearing surface. When the deformable portion 200 is subjected to downward pressure, the deformable segment 210 is inclined at a second included angle relative to the preset plane, allowing it to deform and store a certain amount of elastic potential energy. Similarly, the connecting segment 220 is inclined at a first included angle relative to the preset plane, allowing it to deform and store a certain amount of elastic potential energy. Furthermore, the spring clips 300 are inclined at a third included angle relative to the preset plane, enabling them to also deform and store elastic potential energy. It can generate deformation to store a certain amount of elastic potential energy; furthermore, in the spring of this utility model, the deformation segment 210, the connecting segment 220 and the antenna 300 can all provide a certain amount of elastic support. When one or two of the deformation segment 210, the connecting segment 220 and the antenna 300 fail, the remaining two or one can still continue to work, so that the spring of this utility model has a longer service life. When the spring of this utility model is applied in a connector, under the condition of frequent insertion and removal of male terminal blocks and female terminal blocks, the spring of this embodiment still has a longer service life.

[0034] In some embodiments of this utility model, the angle α of the first included angle satisfies: 10°≤α≤30°, the angle β of the second included angle satisfies: 35°≤β≤40°, and the angle γ of the third included angle satisfies: 20°≤γ≤30°.

[0035] In some embodiments of the present invention, the spring sheet includes a plurality of deformable portions 200, which are spaced apart along the extension direction of the extension portion 100.

[0036] For example, such as Figure 1 As shown, the spring includes multiple deformable parts 200, which are spaced apart along the front-rear direction, and each deformable part 200 has two connecting segments 220 connected to two extensions 100 respectively.

[0037] It is understandable that, since the spring sheet is provided with multiple deformation parts 200, it can have more deformation segments 210 and connecting segments 220, and these deformation segments 210 and connecting segments 220 can all provide a certain elastic support; thus, the provision of multiple deformation parts 200 on the spring sheet can make the elastic support capability of the spring sheet of this utility model stronger.

[0038] In some embodiments of this utility model, each extension 100 is connected to a plurality of tentacles 300, and on the same extension 100, the plurality of tentacles 300 and the plurality of connecting segments 220 are alternately distributed along the extension direction of the extension 100.

[0039] For example, such as Figure 1 As shown, each extension 100 is connected to multiple tentacles 300. On the same extension 100, multiple tentacles 300 are distributed at intervals along the front-back direction, and on the same extension 100, multiple tentacles 300 and multiple connecting segments 220 are alternately distributed along the front-back direction.

[0040] It is understood that the extension 100 is smaller in the left-right direction so that it can bend when subjected to loads in the left-right direction. In the spring of this utility model, since multiple tentacles 300 and multiple connecting segments 220 are alternately distributed along the extension direction of the extension 100, the tentacles 300 and connecting segments 220 can reinforce the structural strength of the extension 100, thereby increasing the load-bearing capacity of the extension 100 in its own width direction.

[0041] In some embodiments of this utility model, along the extension direction of the extension 100, protrusions 210a and grooves 210b are formed at opposite ends of the deformable portion 200, respectively. On a preset plane, between any two adjacent deformable portions 200, the orthographic projection of the protrusion 210a of one deformable portion 200 passes through the orthographic projection of the groove 210b of the other deformable portion 200.

[0042] For example, such as Figure 1 As shown, the front end of the deformable part 200 protrudes forward to form a protrusion 210a, and the rear end of the deformable part 200 is recessed forward to form a groove 210b. On the horizontal plane, between any two adjacent deformable parts 200, the orthographic projection of the protrusion 210a of the deformable part 200 located on the rear side falls into the orthographic projection of the groove 210b of the deformable part 200 located on the front side.

[0043] Understandably, since on the preset plane, between any two adjacent deformation parts 200, the orthographic projection of the protrusion 210a of one deformation part 200 passes through the orthographic projection of the groove 210b of the other deformation part 200, on the one hand, the arrangement of the various deformation parts 200 on the spring sheet can be made more compact, and on the other hand, the various deformation parts 200 on the spring sheet can be formed by processing a single integral plate, thereby reducing the manufacturing cost of the entire spring sheet. Furthermore, when the protrusion 210a of the deformation part 200 is pressed downward, the protrusion 210a will deform downward so as to just insert into the groove 210b of the adjacent deformation part 200, thereby reducing the probability of the deformation part 200 interfering with the adjacent deformation part 200 when it is pressed.

[0044] In some embodiments of this utility model, the end of the protrusion 210a facing away from the groove 210b is provided with a bending structure 210c that bends toward a preset plane.

[0045] For example, such as Figure 1 As shown, the front end of the protrusion 210a is bent downward to form a bent structure 210c.

[0046] It should be noted that when the contact angle 300 of the spring is supported on a horizontal surface, the bending structure 210c in the spring is the tallest structure in the spring. That is, during the operation of the spring, the bending structure 210c in the spring comes into contact with the male terminal block first.

[0047] In the spring of this utility model, a bending structure 210c is provided at the end of the protrusion 210a away from the groove 210b, which is bent toward a preset plane. The bending structure 210c can strengthen the protrusion 210a and improve its load-bearing capacity. At the same time, since the bending structure 210c has an arc-shaped surface, the arc-shaped surface can reduce the damage to the male terminal block and the damage to the arc-shaped surface by the male terminal block during the contact process.

[0048] In some embodiments of this utility model, the deformation segment 210 includes a first deformation region 211, a second deformation region 212, and a third deformation region 213 connected in sequence. In the same deformation part 200, the end of the first deformation region 211 away from the second deformation region 212 is connected to one of the connecting segments 220, and the end of the third deformation region 213 away from the second deformation region 212 is connected to another connecting segment 220. The second deformation region 212 is located on the same side as the two connecting segments 220. The first deformation region 211, the second deformation region 212, and the third deformation region 213 together define a groove 210b, and the second deformation region 212 forms a protrusion 210a.

[0049] For example, such as Figure 1As shown, the deformable portion 200 includes a first deformable region 211, a second deformable region 212, and a third deformable region 213 connected in sequence. The first deformable region 211 extends along the upper right front, the second deformable region 212 extends along the lower right, and the third deformable region 213 extends along the lower right rear. The lower left rear end of the first deformable region 211 is connected to the extension portion 100 located on the left side. The upper right front end of the first deformable region 211 is connected to the upper left end of the second deformable region 212. The lower right end of the second deformable region 212 is connected to the upper left front end of the third deformable region 213. The lower right rear end of the third deformable region 213 is connected to the extension portion 100 located on the right side. The first deformable region 211, the second deformable region 212, and the third deformable region 213 together define a groove 210b. The second deformable region 212 forms a protrusion 210a.

[0050] It is understandable that by dividing the deformable portion 200 into a first deformable region 211, a second deformable region 212, and a third deformable region 213 connected in sequence, when the second deformable region 212 is compressed, the second deformable region 212 can drive the first deformable region 211 and the third deformable region 213 to bend and deform downwards simultaneously, so that the first deformable region 211 and the third deformable region 213 can provide elastic support. At the same time, since the second deformable region 212 extends along the lower right, the first deformable region 211 and the second deformable region 213 can provide elastic support. The angle between the two deformation zones 211 and 212 is different from the angle between the second deformation zone 212 and the third deformation zone 213. After the second deformation zone 212 is compressed, the third deformation zone 213 can deform first to provide elastic support force, and then the first deformation zone 211 will deform to provide elastic support force. This allows the entire deformation part 200 to gradually provide elastic support force when compressed. Under the premise of ensuring that the deformation part 200 can provide sufficient elastic support force, the overall stability of the deformation part 200 can be improved.

[0051] In some embodiments of this utility model, on the same extension 100, any two adjacent antennae 300 are spaced apart by a first distance, and along the extension direction of the extension 100, the size of the antennae 300 is a second distance, and the first distance and the second distance are the same in numerical value.
