Abstract
The utility model discloses an ultralow antenna contact spring piece. The spring piece comprises an elastic contact portion, a bottom portion and an elastic connecting portion, wherein the bottom portion is used for being fixed with a circuit board, the elastic connecting portion is used for connecting the elastic contact portion and the bottom portion, the whole ultralow antenna contact spring piece is in a U shape, the elastic contact portion, the elastic connecting portion and the bottom portion are in an integral structure, a top surface of one end of the elastic contact portion, which is far away from the elastic connecting portion is provided with a protruding point, and the spring piece can be in contact with an electron device reliably through the protruding point. The spring piece has the advantages of being small in thickness after compression, moderate in elastic strength, reliable in contact and the like. The spring piece is used in connection of an internal antenna of a cell phone and a circuit board, the height space of the antenna can be saved, by the aid of the structure of the spring piece, the circuit board is compact in layout and the developing requirements of electronic products for light and thin types are met.
Description
Technical field
The utility model relates to a kind of shell fragment, is specifically related to a kind of antenna contact flat spring.
Background technology
FPC antenna or LDS (laser direct forming) antenna is usually used metal clips when being connected with circuit board, it keeps a rational compression stress under the situation of certain decrement, to guarantee keeping the reliable conducting that contacts between antenna and the circuit board.Common metal clips compression back highly is more than the 0.8mm, is difficult to satisfy that electronic product is lightening, the growth requirement of ultra-thinization, and low again as if the height after the compression of this metal clips, the dynamics of metal clips and elasticity are difficult to meet the demands.
The utility model content
Be the problem overcome the not enough of prior art and to exist, the utility model provides a kind of ultralow antenna contact flat spring, and this shell fragment highly little and its elasticity and dynamics after compression can guarantee the reliability that contacts to satisfy the lightening growth requirement of electronic product.
The utility model is realized through following technical scheme: a kind of ultralow antenna contact flat spring; Comprise elastic contact part, be used for bottom of fixing with circuit board and the elastic joint part that is used to be connected elastic contact part and bottom; Wherein, Described elastic joint part is curved, and the one of which end is connected in an end of bottom, and the other end bends towards the other end of bottom and is connected with elastic contact part; Said shell fragment integral body is arch door shape or U-shaped.Described bottom can be welded on the circuit board through SMT technology.
Further, described elastic contact part is provided with salient point on the end face away from an end of elastic joint part, and this salient point can make this shell fragment contact more reliable with extraneous electronic device (like the FPC antenna); The end that described elastic contact part and elastic joint part connect is a straight-arm parallel with the bottom, and the other end is the arc elastic arm of an evagination.
Further, described elastic contact part, elastic joint part and the bottom structure that is one of the forming.
The utility model and prior art are relatively; Have advantages such as compression back thickness is little, the elasticity dynamics is moderate, contact is reliable; Be applied in being connected of built-in antenna of mobile phone and circuit board; Can save the height space of antenna, the structure of this shell fragment of while also is convenient to circuit board and is got layout, is convenient to realize that electronic product is lightening.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the perspective view of the utility model embodiment.
Embodiment
For the ease of those skilled in the art's understanding, the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.
Like accompanying drawing 1, shown in 2; A kind of ultralow antenna contact flat spring; The elastic joint part 3 that comprises elastic contact part 2, is used for the bottom of fixing with circuit board 1 and is used to be connected elastic contact part 2 and bottom 1, described bottom 1 can be welded on the circuit board through SMT (surface mounting technology) technology.Said shell fragment integral body is arch door shape or U-shaped, described elastic contact part 2, elastic joint part 3 and bottom 1 structure that is one of the forming.Described elastic joint part 3 takes the shape of the letter U, and the one of which end is connected in an end of bottom 1, and the other end bends towards the other end of bottom 1 and is connected with elastic contact part 2.
Described elastic contact part 2 is provided with salient point 4 on the end face away from elastic joint part 3 one ends, this salient point 4 can make this shell fragment contact more reliable with extraneous electronic component (like the FPC antenna); The end that described elastic contact part 2 and elastic joint part 3 connects is a straight-arm 22 parallel with bottom 1, and the other end is the arc elastic arm 21 of an evagination.
This shell fragment highly is about 0.4mm after being compressed to the end, and elastic force and stroke can satisfy the contact reliability requirement, in being connected of the FPC antenna that is applied to embedded in mobile phone and circuit board, can save the mobile phone thickness space, satisfies ultra-thinization of product growth requirement; Simultaneously, the structure of this shell fragment is convenient to circuit-board laying-out and complete machine piles up; In addition, it is little that this shell fragment also has size, produces advantages such as simple, with low cost.
The foregoing description is the preferable implementation of the utility model, is not to be the qualification to the utility model, and under the prerequisite of the inventive concept that does not break away from the utility model, any conspicuous replacement is all within the protection range of the utility model.
