Abstract
The invention relates to a clamp groove type connecting structure for a radio frequency coaxial cable and a printed circuit board (PCB). The clamp groove type connecting structure comprises the PCB printed with a radio frequency line and the radio frequency coaxial cable and is characterized in that a clamp groove is arranged on the PCB, the end portion of the radio frequency coaxial cable is clamped into the clamp groove, a core line of the radio frequency coaxial cable is in welding connection with the radio frequency line, and a shielding layer of the radio frequency coaxial cable is connected with the reference ground on the PCB. The other technical scheme is that the invention provides a clamp groove type connecting method for the radio frequency coaxial cable and the PCB. After adopting the clamp groove type connecting method for the radio frequency coaxial cable and the PCB, the total thickness (only less than 0.3mm of PCB thickness can be increased) of the welded PCB can be decreased to the most extent, and attenuation of a radio frequency signal can be reduced. In addition, radio frequency connectors are decreased so that the overall cost can be reduced.
Description
Technical field
The present invention relates to card slot type syndeton and method between a kind of radio frequency coaxial-cable and pcb board, belong to syndeton and method and technology field between radio frequency coaxial-cable and pcb board.
Background technology
Along with the miniaturization of market to portable equipment requires to get more and more, handheld device is also complied with and is done thinner and thinner, and this thickness to various components and parts and mechanism's part has proposed great challenge.For antenna some structures and technical limitations, that must use the PCB circuit design, how on the basis of PCB own, no longer to increase the height of extra radio frequency line welding or radio frequency socket, become a kind of demand.
Summary of the invention
The purpose of this invention is to provide a kind of radio frequency coaxial-cable and the syndeton between pcb board and method of attachment that reduces to greatest extent the PCB antenna thickness.
In order to achieve the above object, a technical scheme of the present invention has provided the card slot type syndeton between a kind of radio frequency coaxial-cable and pcb board, comprise the pcb board and the radio frequency coaxial-cable that are printed with radio frequency line, it is characterized in that: have a draw-in groove at pcb board, the end of radio frequency coaxial-cable snaps in this draw-in groove, heart yearn and the radio frequency line of radio frequency coaxial-cable are welded to connect, and the reference ground on the screen of radio frequency coaxial-cable and the pcb board links to each other.
Another technical scheme of the present invention has provided the card slot type method of attachment between a kind of radio frequency coaxial-cable and pcb board, it is characterized in that, step is:
The first step, connect the position card groove of radio frequency coaxial-cable at the pcb board that is printed with radio frequency line, the width of draw-in groove is suitable with the external diameter of radio frequency coaxial-cable;
Second step, the end of radio frequency coaxial-cable is successively peeled off respectively by heart yearn, insulating barrier, screen and PVC coating respectively, this end of peeling off is snapped in the draw-in groove;
The 3rd the step, with flatiron heart yearn is welded to radio frequency line, screen then with pcb board on reference link to each other.
After adopting the card slot type syndeton and method between a kind of radio frequency coaxial-cable provided by the invention and pcb board, can reduce to greatest extent on the one hand the gross thickness (pcb board on thickness, only can increase be less than 0.3mm) of pcb board after the welding, can reduce on the other hand the decay of radiofrequency signal, simultaneously, can reduce whole cost owing to reduced the radio frequency connector.
Description of drawings
Fig. 1 is schematic diagram after the radio frequency coaxial-cable among the embodiment is connected with pcb board.
Embodiment
For the present invention is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, present embodiment provides the syndeton of the card slot type between a kind of radio frequency coaxial-cable and pcb board, comprise the pcb board 1 and the radio frequency coaxial-cable 3 that are printed with radio frequency line 7, have a draw-in groove 2 at pcb board 1, the end of radio frequency coaxial-cable 3 snaps in this draw-in groove 2, the heart yearn 4 of radio frequency coaxial-cable 3 is welded to connect with radio frequency line 7,6 links to each other to reference on the screen 5 of radio frequency coaxial-cable 3 and the pcb board 1.
The present invention also provides the method for attachment of the card slot type between a kind of radio frequency coaxial-cable and pcb board, the steps include:
The first step, connect the position card groove 2 of radio frequency coaxial-cable 3 at the pcb board 1 that is printed with radio frequency line 7, the external diameter of the width of draw-in groove 2 and radio frequency coaxial-cable 3 is suitable;
Second step, the end of radio frequency coaxial-cable 3 is successively peeled off respectively by heart yearn 4, insulating barrier 8, screen 5 and PVC coating 9 respectively, this end of peeling off is snapped in the draw-in groove 2;
The 3rd step, with flatiron heart yearn 4 is welded to radio frequency line 7,6 links to each other to the reference on 5 of screens and the pcb board 1.
After adopting the card slot type connected mode between radio frequency coaxial-cable provided by the invention and pcb board, the thickness of pcb board is increased to 1.85mm from original 1.6mm, and the thickness of increase is no more than 0.3mm, and radio frequency signal attenuation is also less than 0.3dB simultaneously.
Card slot type connected mode between a kind of radio frequency coaxial-cable provided by the invention and pcb board has overcome the gross thickness of pcb board that existing radio frequency coaxial-cable mostly is the radio frequency connector or directly is welded in the interconnection technique on PCB surface increases problem, for reducing, the gross thickness of pcb board provides a kind of new approaches, be convenient to simultaneously weld and save the cost of a radio frequency connector, this welding manner can also be applied in other mechanism's requirement that need to reduce thickness.
