Be connected with antenna for mobile phone by the shell fragment of design, the height designed by type not of the same race is different, required shell fragment height and shape also different, and this type of shell fragment height existing is generally all higher.There is following problem in it:
1. various structures, increases difficulty for unified management.And cost is high.
2. existing shell fragment easily occurs when volume production being operated all to point hitching distortion.
3. now shell fragment cannot realize multiple type version and shares.
4. cannot meet the use of very thin type.
Therefore very thin type requires at very low operation height, and current antenna shrapnel cannot provide enough elastic force, and the elastic force of antenna shrapnel cannot reach designing requirement, crimping is unstable, cause electrical connection properties to decline, affect the communication signal of mobile phone, be therefore necessary to be improved.
Utility model content
In order to overcome the deficiency of above technology, the purpose of this utility model is to provide a kind of mobile phone shell fragment.
The utility model provides: a kind of mobile phone shell fragment, it comprises a base portion, a pressure connection terminal is extended in one end of base portion, described pressure connection terminal is positioned at the top of base portion after inverse bending, and bending section forms elastic arm, the other end both sides of base portion are extended stop section, invayination is formed after the inside bending in last point of described stop section, described invayination to be positioned at above elastic arm and to keep out described elastic arm, the outer end inverse bending of described pressure connection terminal goes out a head fulcrum, described head fulcrum is between pressure connection terminal and base portion, described elastic arm is kept out by invayination after being moved downwardly over initial position, a precompression is there is in described elastic arm at initial position, after pressure connection terminal presses down, head fulcrum is crimped on pedestal and forms crimping fulcrum.
Described crimping fulcrum is that head fulcrum upwards bends rear formation, and the contact-making surface of itself and base portion is cambered surface.
Described head fulcrum and pressure connection terminal connect into U-shaped.
Described invayination, stop section and base portion connect into U-shaped.
Described elastic arm has the projection being bent upwards setting from described base portion one end, a junction is extended from described projection, a bend is bent to form from described connecting portion, direction from described bend towards described base portion has extended to form an extension, described extension connects described pressure connection terminal and described bend, and described contact-segment upwards bends setting from described extension.
Described pressure connection terminal is inclined to set on elastic arm.
Described invayination is resisted against the position of the contiguous described pressure connection terminal in described extension.
Described base bottom is provided with pad.
The utility model structure is simple, and under working depth extremely low in frivolous shape mobile phone requires, antenna shrapnel still can provide high-tension, ensures the stability of antenna crimping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As depicted in figs. 1 and 2, the utility model provides with mobile phone shell fragment, and it is bent to form by a sheet metal punching press, and it comprises a base portion 2, and described base portion is tabular, and below is fixedly installed pad 1, makes welding convenient and fixing more firm.
A pressure connection terminal 11 is extended in one end of base portion 2, described pressure connection terminal 11 is positioned at the top of base portion 2 after inverse bending, and bending section forms elastic arm, the other end both sides of base portion 2 are extended stop section 8, invayination 7 is formed after the inside bending in last point of described stop section 8, described invayination 7 to be positioned at above elastic arm and to keep out described elastic arm, the outer end inverse bending of described pressure connection terminal 11 goes out a head fulcrum 12, described head fulcrum 12 is between pressure connection terminal 11 and base portion 2, kept out by invayination 7 after described elastic arm is moved downwardly over initial position, a precompression is there is in described elastic arm at initial position.
Because of the restriction by product work height and total height, the elastic force of existing structure cannot reach the requirement of regulation.Present pressure connection terminal 11 outer end increases head fulcrum 12, for the formation of an elastic support structure, press down in process at pressure connection terminal 11, head fulcrum 12 can be connected to base portion 2, for antenna shrapnel provides extra elastic force, thus have enough elastic force to ensure stable crimping, the requirement that prior art does not reach can be realized, after pressure connection terminal 11 presses down, head fulcrum 12 is crimped on base portion 2 and forms crimping fulcrum 13, described crimping fulcrum is upwards bent to form by head fulcrum, the contact-making surface of itself and base portion is cambered surface, formation face contacts with face, improve contact effect, the useful life of further prolongation shell fragment.
Projection 3 is upwards bent to form again from one end of described base portion 2, described projection 3 prevents the generation of siphonage, then described connecting portion 4 is extended to form successively, described connecting portion 4 and described base portion 2 are positioned at same level, and benchmark is consistent, make and are easier to control, upwards bending extends to form described bend 5, direction horizontal-extending towards described base portion 2 forms described extension 6, and extension is used for automatic placement machine and draws, and plays automation effect and the productivity of energy stable prod.Described extension 6 and described base portion 2 and described connecting portion 4 be arranged in parallel, make easy, upwards bending extends to form described contact-segment 10, the top of described contact-segment 10 forms the described pressure connection terminal 11 of arc, described head fulcrum 12 is oppositely bent to form towards the direction near extension 6 from described pressure connection terminal 11, described head fulcrum 12 part is lower than the top of described pressure connection terminal 11, the described elastic arm of formation like this, the bottom of described head fulcrum 12 is upwards bent to form crimping fulcrum 13, and described crimping fulcrum 13 is cambered surface with the contact-making surface of base portion 2.
Described contact-segment 10 and the not parallel setting of described connecting portion 4.
Described base portion both sides arrange stop section 8, two ends bending from described stop section 8 near described extension 6 is provided with an invayination 7, described invayination 7 part keeps out the position of the contiguous described contact-segment in described extension 6 of described elastic arm downwards, described invayination is that described extension 6 is kept out at punching press edge, and namely described invayination 7 utilizes metal plate to keep out the metal plate of described extension 6.Two stop sections 8 are set to limit the excessive horizontal displacement of described elastic arm 2, simultaneously upwards extend to form afterbody at the rear side of stop section 8, this afterbody higher than the height of described invayination, for the excessive level displacement of Restricted Contact section 10.
