Description
Technical field
The utility model relates to a kind of spring clip, especially relates to a kind of printed circuit board (PCB) and connects other electric original papers or earthing spring folder.
Background technology
Spring clip is also referred to as shielding spring, ground spring or general earthing contact in mobile phone industry, almost are used to each miniature printed circuit board, spring clip is the internal connector that install on a kind of single contact, surface, can be used in the electrical connection and ground connection of printed circuit board (PCB) and other electronic components.
Spring clip is very high to the requirement for height of contact shell foot, yet it is difficult to the dimension control of metal elastic gonosome to work as its production technology.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of height of can accurately controlling for the defective that overcomes above-mentioned prior art existence, and the printed circuit board (PCB) reliable, that the life-span is long connects uses spring clip.
The purpose of this utility model can be achieved through the following technical solutions: a kind of printed circuit board (PCB) connects uses spring clip, it is characterized in that, comprise the first cantilever, the second cantilever, contact shell foot and spacing flanging, described the first cantilever one end connects the second cantilever, the other end connects the contact shell foot, described spacing flanging one end is fixedly connected with the second cantilever, the other end with contact the shell foot clamping.
The angle that described the first cantilever and the second cantilever open the 1-30 degree laterally.
The head of described the first cantilever connects the contact shell foot, and this head upwards lifts, and forms the angle that is the 1-30 degree with afterbody place horizontal plane.
Described contact shell foot is inverted U, and its openend one pin connects the first cantilever, and the other end is provided with outward extending flanging a.
Described spacing flanging one end connects the second cantilever, and the other end is provided with the flanging b that extends internally, this flanging b and the clamping of described flanging a coupling.
Described spacing flanging one end connects the second cantilever, and the other end is provided with spacing hole, and described flanging a inserts this spacing hole clamping.
Described contact shell foot top connecting electronic components and parts or ground connection.
Described the second cantilever is welded on the printed circuit board (PCB).
Compared with prior art, the utility model is because two cantilevers have outwards opened certain angle, under free state, spacing flanging limits the height of contact shell foot, can effectively control electronic devices and components to the decrement of contact shell foot, the reliability of contact is provided, lower in working order, the second cantilever of spring clip is welded on the pcb board, and the contact shell foot is compressed by electronic devices and components, spring clip improves the life-span of spring clip with the outside elastic force offset pressure of the first cantilever.
