The limit card head 3 is fastened in the corresponding limit card slot 5 to fasten the two free ends (the limit portion and the fixed portion) of the elastic piece.
其中，限位卡头3进一步包括构成“T”形的横向的卡持部和垂直于卡持部并与弹性力臂连接的延伸部，限位卡槽为与限位卡头相适配的“⊥”形结构，包括构成“⊥”形的横向的进入槽51和垂直于进入槽51的限位槽52；限位卡头被配置为在卡持部由进入槽51穿过后，在弹性力臂的作用下向上运动，延伸部卡设在限位槽52内。The limit clip 3 further includes a laterally-shaped catch portion constituting a "T" shape and an extension portion perpendicular to the latch portion and connected to the elastic force arm, and the limit card slot is adapted to the limit card holder. The "⊥"-shaped structure includes a lateral entry groove 51 constituting a "⊥" shape and a limit groove 52 perpendicular to the entry groove 51; the limit chuck is configured to be elastic after the catch portion is passed through the entry groove 51 The arm moves upwards under the action of the force arm, and the extension portion is locked in the limiting groove 52.
具体地，图1示出了根据本实用新型实施例的导电弹片的限位卡头3与限位卡槽5未扣合之前的状态；图2示出了根据本实用新型实施例的导电弹片的限位卡头3与限位卡槽5扣合之后的状态。Specifically, FIG. 1 illustrates a state before the limit clip 3 of the conductive elastic piece and the limit card slot 5 are not fastened according to an embodiment of the present invention; FIG. 2 illustrates a conductive elastic piece according to an embodiment of the present invention. The state after the limit card head 3 is engaged with the limit card slot 5.
在本实用新型的一个具体实施方式中，限位卡槽5为“⊥”字形结构，包括进入槽51和限位槽52，限位卡头3的延伸部具有向下弯折的下弯部，在固定部上设有用于避让下弯部的避让槽11；换言之，为能够顺利的将限位卡头3限位在限位卡槽5内，在固定部1上与固定块4相接的一端设置有水平的避让槽11，进入槽51与避让槽11连通，限位槽52设置在进入槽51靠近限位部的一侧，并且限位槽52的截面宽度小于进入槽51的横截面宽度。In a specific embodiment of the present invention, the limiting card slot 5 has a U-shaped structure, including an entry slot 51 and a limiting slot 52. The extension of the limiting clip 3 has a downwardly bent downward bend. The escaping groove 11 for escaping the lower bent portion is provided on the fixing portion; in other words, the limit ferrule 3 can be smoothly restrained in the limit card slot 5, and is connected to the fixed block 4 on the fixed portion 1. One end of the escaping groove 11 is provided, and the inlet groove 51 communicates with the escaping groove 11. The limiting groove 52 is disposed on a side of the inlet groove 51 near the limiting portion, and the sectional width of the limiting groove 52 is smaller than the horizontal width of the inlet groove 51. Section width.
此外，限位卡头3与进入槽51对应设置，在对导电弹片进行扣合时，在避让槽11的作用下，限位卡头3从对应的进入槽51进入限位卡槽5内，然后在弹性力臂2的弹力作用下，向上运动并卡在限位槽52内。为确保限位卡槽5对限位卡头3的限位作用，在本实用新型的导电弹片中，限位卡头3的
最大尺寸小于进入槽51的尺寸，并大于限位槽52的尺寸，从而确保限位卡头顺利通过进入槽51并限位在限位槽52内。In addition, the limiting clip 3 is disposed corresponding to the access slot 51. When the conductive elastic piece is engaged, the limiting chuck 3 enters the limiting slot 5 from the corresponding access slot 51 under the action of the escape slot 11. Then, under the elastic force of the elastic force arm 2, it moves upward and is caught in the limiting groove 52. In order to ensure the limit function of the limit card slot 5 to the limit card head 3, in the conductive elastic piece of the present invention, the limit card head 3
The maximum size is smaller than the size of the access slot 51 and larger than the size of the limiting slot 52, thereby ensuring that the limiting clip passes smoothly into the slot 51 and is limited to the limiting slot 52.
需要说明的是，由于进入槽51和避让槽11相互导通，避让槽11和限位槽52分别设于进入槽51的两侧，致使限位卡槽5形成近似“十”字形结构，为简化导电弹片的制作工艺，可直接将本实用新型实施例的限位卡槽5设置为“十”字形结构，避让槽11、进入槽51和限位槽52一次取料形成，在安装过程中，限位卡头3从对应的进入槽51进入限位卡槽5内，然后在弹性力臂2的弹力作用下，向上运动并卡在限位槽52。此时，在导电弹片受外力下压时，能够有效避免限位卡头3从进入槽51内脱离。It should be noted that, since the inlet groove 51 and the relief groove 11 are electrically connected to each other, the relief groove 11 and the limiting groove 52 are respectively disposed on both sides of the inlet groove 51, so that the limiting card slot 5 forms an approximately "ten" shape. The simplification of the manufacturing process of the conductive elastic piece can directly set the limiting card slot 5 of the embodiment of the present invention to a "ten" shape structure, and the avoidance groove 11, the inlet groove 51 and the limiting groove 52 are formed at one time, during the installation process. The limit chuck 3 enters the limit slot 5 from the corresponding entry slot 51, and then moves upward and is caught in the limit slot 52 by the elastic force of the elastic arm 2. At this time, when the conductive elastic piece is pressed by an external force, the restriction chuck 3 can be effectively prevented from being detached from the entry groove 51.

When the voice coil has an audio current flowing, it will be subjected to an alternating driving force to generate an alternating motion, thereby driving the diaphragm to vibrate, and then repeatedly pushing the air to make a sound.
通过上述实施方式可以看出，本实用新型提供的导电弹片以及设置有该导电弹片的电子设备，在导电弹片的限位部设置“T”形结构的限位卡头，在其固定块上设置与限位卡头相对应的限位卡槽，通过限位卡槽实现对限位卡头的牢固限位，能够有效避免导电弹片的运输过程中或者产线使用过程中，限位卡头从限位卡槽内脱离，从而提高导电弹片的可靠性及稳定性，对应的电子设备性能稳定、合格率高。It can be seen from the above embodiments that the conductive elastic piece provided by the present invention and the electronic device provided with the conductive elastic piece are provided with a "T"-shaped limit clamp head in the limiting portion of the conductive elastic piece, and are disposed on the fixed block thereof. The limit card slot corresponding to the limit card head realizes the solid limit of the limit card head through the limit card slot, which can effectively avoid the transportation of the conductive elastic piece or the use of the production line during the use of the limit card head The limit card slot is detached, thereby improving the reliability and stability of the conductive elastic piece, and the corresponding electronic device has stable performance and high qualification rate.
