Anti-elasticity structure of electrode plate outer cover

Abstract

The utility model discloses an anti-elasticity structure of an electrode plate outer cover, which comprises an upper cover body with an inner cavity, a thin film circuit board and a lower shell are arranged in the inner cavity of the upper cover body, and the lower shell is arranged at the lower part of the thin film circuit board. The edge part of the lower end surface of the lower shell is provided with a groove, the width of the groove of the lower shell is more than 2mm, and the depth of the groove aims at enabling the outer wall of the groove to generate elastic deformation. The edge of the lower shell with inclination can have enough space to enable the first side wall to be shrunk, and when the lower shell is shrunk, due to the fact that the lower shell is provided with the groove, when a force reaches the groove, the outer wall of the groove is prone to deformation, the elastic space plasticity of the shrunk shape can be effectively improved, and inward shrunk shaping of the first side wall of the upper cover body is facilitated.

Description

TECHNICAL FIELD

[0001] The utility model relates to the electrode piece switch field, especially touch type electrode piece switch field. BACKGROUND

[0002] In some intelligent electric appliances, there is a light touch electrode piece switch, which has a built-in thin film circuit board. An upper cover and a lower shell sandwich the thin film circuit board for fixation. The upper cover is usually made of a metal sheet for aesthetic appearance. The metal sheet has an inner cavity for accommodating the thin film circuit board and the lower shell. When the metal sheet is stretched, the side wall will spread outward due to the elastic properties of the metal. The spread shape will not be aesthetically pleasing when installed on an electric appliance or electronic product, and it is easy to interfere with other components. SUMMARY

[0003] To solve the above problems, the utility model provides a kind of elastic structure of electrode piece cover, it includes the upper cover with inner cavity, the inner cavity of upper cover is provided with thin film circuit board and lower shell, lower shell is placed in the lower part of thin film circuit board, the edge side of lower shell is set to the inclined surface of inward inclination, and the edge of the lower end surface of lower shell is provided with recess.

[0004] Further, the width of the recess of the lower shell is more than 2mm, and the depth is targeted at the elastic deformation of the outer wall of the recess.

[0005] Further, the first side wall of the upper cover is also provided with uniformly distributed folding tabs.

[0006] Further, the upper cover is a metal sheet with good elasticity.

[0007] Further, the lower shell is made of plastic material.

[0008] Using the utility model scheme, after the thin film circuit board and the lower shell are installed on the upper cover, the first side wall is shaped inwardly, and the lower shell edge with slope has enough space for the first side wall to be shaped. When shaping, the lower shell has a recess, and when force reaches, the outer wall of the recess is easy to deform, so that the elastic space of shaping can be effectively improved.

[0013] According to Figs. 1-3 As shown in the utility model discloses an embodiment, provide a kind of bulletproof structure of electrode piece cover, it includes the upper cover body 1 with inner cavity, the inner cavity of upper cover body 1 is provided with thin film circuit board 2 and lower shell 3, lower shell 3 is placed in the lower part of thin film circuit board 2, the edge side portion 31 of lower shell 3 is set to inwardly inclined inclined surface 312, the edge portion of the lower end surface of lower shell 3 is provided with recess 311.

[0014] In the embodiment, the width of the recess of the lower shell is 2mm or more, and the depth is targeted to enable the elastic deformation of the outer wall 31 of the recess, when the shrinkage mold presses the first side wall 11 of the upper cover body 1 inwardly, the edge side portion 31 of the lower shell 3 has enough space to allow the first side wall 11 of the upper cover body 1 to run inwardly, at the same time, the recess 311 of the lower shell 3 can enable the elastic inward deformation of the outer wall 313 of the recess, which is more beneficial to the inward running of the first side wall 11 of the upper cover body 1, that is, the inward shrinkage of the first side wall 11 of the upper cover body 1 is realized.

[0015] In the embodiment, the first side wall 11 of the upper cover body 1 is also provided with uniformly distributed folding pressing pieces 111, which are bent and pressed to fix the lower shell 3 after the first side wall 11 of the upper cover body 1 is shrunk inwardly, and have the effect of auxiliary fixation.

[0016] In the embodiment, the upper cover body 1 is a metal sheet with good elasticity, which is beneficial to the appearance and can produce deformation.

[0017] In the embodiment, the lower shell 3 is made of plastic material, which is more beneficial to elastic deformation in the structure of the recess.

[0018] The above only describes preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
