Abstract
The invention relates to an elastic sheet. The elastic sheet is electrically connected with a PCB (Printed Circuit Board) and an electronic element; the elastic sheet comprises a bending part, a fixed part, an elastic arm and a butting part, wherein the fixed part is fixed on the PCB; the bending part is formed by reversely bending one end of the fixed part; the elastic arm is parallel to the fixed part; one end of the elastic arm is connected with the bending part; the butting part is arranged at the other end of the elastic arm and is abutted with the electronic element; the fixed part is provided with a protection fence for protecting the butting part; and the butting part and the protection fence are provided with pre-pressing mechanisms matched with each other. Compared with the prior art, according to the elastic sheet, the pre-pressing force of the elastic sheet is more convenient to adjust, and the protection fence is provided and is used for protecting the elastic sheet to be not damaged by an external force in processes of manufacturing, packaging, transporting, welding and assembling and the like.
Description
Technical field
The present invention relates to a kind of shell fragment, especially relate to a kind of shell fragment that is used to electrically connect circuit board and electronic component.
Background technology
Along with the function of electronic product increase day by day and people promote the requirement of the security performance of electronic product; In the system of electronic product; The shell fragment of the electronic device of connection PCB and some other specific function is by a large amount of utilizations, and is in order to reach reliable electric connection and assembling effect easily, more and more to the structural requirement of shell fragment; Should guarantee to connect between the electronic device of shell fragment and its crimping enough positive pressure are arranged; Require the consistency of height dimension again, elastic piece structure is not destroyed in the time of also will avoiding assembling, and the product periphery has corresponding protection structure.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of shell fragment that is used to electrically connect circuit board and electronic component to be provided.
The object of the invention can be realized through following technical scheme:
A kind of shell fragment, this shell fragment electrically connects PCB circuit board and electronic component, and shell fragment comprises kink, fixed part, elastic arm and abutting part; Described fixed part is fixed on the PCB circuit board, and described kink oppositely is bent to form by an end of fixed part, and described elastic arm is parallel with fixed part; One end of elastic arm connects kink; Described abutting part is located at the other end of elastic arm, with the electronic component butt, it is characterized in that; Described fixed part is provided with the protection fence that is used to protect abutting part, and described abutting part is provided with the precompressed mechanism that cooperatively interacts with the protection fence.
Described precompressed mechanism comprises precompressed projection that is located on the abutting part and the precompressed draw-in groove that is located on the protection fence, and described precompressed projection is fastened in the precompressed draw-in groove.
Described abutting part is the U type, comprises two ends and an arc sections, and described elastic arm is connected with an end, and described precompressed draw-in groove is located on another end, and described electronic component is connected to arc sections.
Compared with prior art; Prepressing structure of the present invention is positioned at the end away from kink; Make its precompression of being convenient to regulate abutting part more, and through be provided with the protection fence can protect shell fragment in processes such as manufacturing, packing, transportation, welding and assembling not by outside destroy.
Description of drawings
Fig. 1 is a perspective view of the present invention;
Fig. 2 is a main TV structure sketch map of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
Fig. 1 and Fig. 2 are the structural representation of an embodiment of the present invention, and this shell fragment has comprised fixed part 1, kink 2, elastic arm 3, abutting part 4 and protection fence 5.Wherein, fixed part 1 generally is welded on the PCB circuit board, and kink 2 oppositely is bent to form by an end of fixed part 1, and connects an end of elastic arm 3.The other end of elastic arm 3 is provided with the U type abutting part 4 that contacts with electronic component.An end of this U type abutting part 4 is connected with elastic arm 3, and another end then is provided with two precompressed projections 40, and 41 butt electronic components of the arc sections of U type under the effect of elastic arm 3, can be close to electronic component, avoid loose contact.The protection fence 5 be arranged on the fixed part 1, be mainly used in the protection abutting part 4 in processes such as manufacturing, packing, transportation, welding and assembling not by outside destroy.Protection fence 5 is provided with precompressed draw-in groove 50, and the precompressed projection 40 of abutting part 4 can be fastened in this precompressed draw-in groove 50, can make abutting part 4 that certain normal pressure is just arranged when the contact electronic device.
Whole shell fragment is a fulcrum with kink 2, produces elastic deformation, and the precompressed mechanism by precompressed draw-in groove 50 and precompressed projection 40 constitute is positioned at the end away from kink 2, is positioned at the structure at shell fragment middle part compared to precompressed mechanism, is more convenient for regulating the precompression of abutting part 4.
Claims (3)
