Abstract

The utility model relates to a novel spiral shell fragment, including the bottom plate and rather than integrated into one piece's contact shell fragment with support the shell fragment, the tip of contact shell fragment has the contact plate that prevents shell fragment production torticollis, laterally offset, the contact plate is mushroom capitiform form, the utility model discloses a contacting area of contact shell fragment is the first structure of mushroom, and there is a plane centre, and has the fillet design all around, can effectively guarantee the contact, can effectively reduce general little protruding inclusion again and construct the shell fragment that leads to and produce torticollis, laterally offset phenomenon.

Description

A kind of Novel spiral shell fragment

Technical field

This utility model is related to a kind of technical field of spiral spring plate.

Background technology

The small product size of spiral spring plate is little, is formed from upper surrounding from lower by two shell fragments, can effectively save PCB space (long Wide height is controlled within 1.5mm).And mutual two circular shell fragments are functionally divided into 1# contact flat springs and 2# supports bullet Piece.Formed in contact site and supported up and down, it is ensured that product Elastic Contact performance.When there is shell fragment and push in similar products in the market Torticollis, causes elastic arm side to be interfered with backplate, and elastic arm lower section produces rigid interference with base plate and causes elastic arm to be bent Clothes deformation, so as to affect the reliability and service life of shell fragment contact.

Utility model content

The purpose of this utility model be solve the problems, such as it is set forth above, there is provided a kind of simple structure, improve shell fragment contact can By property and extend a kind of Novel spiral shell fragment of its service life.

The technical scheme for realizing this utility model purpose is：A kind of Novel spiral shell fragment of this utility model, including base plate and With its integrally formed contact flat spring and support shell fragment, the end of the contact flat spring has prevents shell fragment from producing torticollis, lateral The contact plate of skew, the contact plate are mushroom-head shape.

A kind of further described Novel spiral shell fragment, the mushroom header structure of the contact plate have plane for middle, Its surrounding is fillet structure.

A kind of further described Novel spiral shell fragment, also including contact flat spring backplate, the contact flat spring backplate One end is connected with base plate, and the elastic arm on the outside of contact flat spring and to contact flat spring shields.

A kind of further described Novel spiral shell fragment, the support shell fragment include support elastic arm and gripper shoe.

A kind of further described Novel spiral shell fragment, the support elastic arm be wavy shaped configuration, for depressing when Effectively dispersed deformation, it is to avoid pushing process elasticity arm lower section and producing rigid interference with base plate causes elastic arm to be bent Clothes.

Further described a kind of Novel spiral shell fragment, also including support backplate, described support backplate one end and base plate Connection, positioned at support shell fragment on the outside of and to support shell fragment shell fragment arm shield.

This utility model has positive effect：1st, the contact site of contact flat spring of the present utility model is tied for mushroom head Structure, centre have facet, and surrounding has fillet design, and contact can be effectively ensured, and can effectively reduce general little convex closure structure again Caused shell fragment produces torticollis, laterally offset phenomenon.

2nd, support flexure strip of the present utility model devises waveform feature as support, effectively dispersed bullet Property deformation of piece when pushing, it is to avoid pushing process elasticity piece lower section and producing rigid interference with base plate causes elastic arm surrender to become Shape.

Description of the drawings

In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and with reference to attached Figure, is described in further detail to this utility model, wherein

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the waveform elastic arm schematic diagram for supporting shell fragment.

Fig. 3 is base plate and the gripper shoe schematic diagram for supporting shell fragment.

Specific embodiment

As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of Novel spiral shell fragment, including base plate 7 and with its integrally formed contact flat spring 1 and shell fragment 4 is supported, the end of the contact flat spring 1 has prevents shell fragment from producing torticollis, the contact plate 3 of laterally offset, described to connect Touch panel 3 is mushroom-head shape.The mushroom header structure of the contact plate 3 has plane for middle, and its surrounding is fillet structure.Also wrap Contact flat spring backplate 2 is included, one end of the contact flat spring backplate 2 is connected with base plate 7, on the outside of contact flat spring 1 and to contact The elastic arm of shell fragment 1 shields.The support shell fragment 4 is connected with gripper shoe 6 comprising support elastic arm.It is described to support elasticity Arm is wavy shaped configuration, for depressing when dispersed deformation, it is to avoid push process elasticity arm lower section and produce firmly with base plate 7 Property interfere cause elastic arm to be surrendered.Also include supporting backplate 5,5 one end of the support backplate to be connected with base plate 7, positioned at support bullet On the outside of piece 4 and to support shell fragment 4 shell fragment arm shield.

Particular embodiments described above, has carried out entering one to the purpose of this utility model, technical scheme and beneficial effect Step is described in detail, be should be understood that to the foregoing is only specific embodiment of the utility model, is not limited to this Utility model, all in spirit of the present utility model and principle, any modification, equivalent substitution and improvements done etc. all should be wrapped It is contained in the interior of protection domain of the present utility model.
