[embodiment]
Be further detailed below in conjunction with accompanying drawing.
Shown in Fig. 1 (a), connect the schematic diagram of coaxial cable and circuit board for the mode that adopts connector.This connector comprises socket 1 and plug 2, and wherein socket 1 electrically connects with circuit board 3, and plug 2 electrically connects with coaxial cable 4, and the cooperation by plug 1 and socket 2 can be connected circuit board 3 with coaxial cable 4.
Shown in Fig. 1 (b), connect the schematic diagram of coaxial cable and circuit board for traditional employing welding manner.Its standard coaxial cable 4 is followed successively by center conductor 41, insulating barrier 42, screen 43 and overcoat 44 from the inside to the outside.Microstrip line 31 on the circuit board 3 and center conductor 41 welding, screen 43 is by ground pad 32 and circuit board 3 welding ground connection.
Connector can not satisfy the needs of miniaturization, and directly the mode of welding then causes the instability of connection.
In the utility model one embodiment, a kind of coaxial cable weld fixture apparatus is provided, this coaxial cable weld fixture apparatus comprises a holding section, the general employing in this holding section has good conductivity and has certain flexible metal makes.The holding section be fixed on the circuit plate body and with the circuit plate body between form ground connection and be connected.When the microstrip line with coaxial cable and circuit board welded, the holding section tightens coaxial cable, need not other holders and holds up measure can stablize welding, and was easy to operate, and welding is good afterwards also comparatively firm, is difficult for getting loose.
As shown in Figure 2, coaxial cable weld fixture apparatus for another preferred embodiment of the utility model, this coaxial cable weld fixture apparatus comprises the holding section 10 and the fixing feet 20 that is used for being connected with circuit board that is used to hold coaxial cable, and fixing feet 20 is located at the lateral wall of holding section 10.
In the foregoing description, holding section 10 sidewalls can be solid plate body or skeleton structure, preferably, can select for use skeleton structure to save material.
As shown in Figure 5, be the schematic diagram of the printed circuit board (PCB) of the utility model one embodiment.This printed circuit board (PCB) comprise be located on its circuit plate body 30 as the described coaxial cable weld fixture apparatus of above-mentioned embodiment.Be furnished with the microstrip line 302 that is connected with the outer, coaxial cable on the circuit plate body 30, the position corresponding with pin 204 is provided with ground connection via hole 304, is preferably 4 equally.Offer slot to make way 306 in the position corresponding in addition with holding section 10.
When producing, pin 204 is pressed into ground connection via hole 304 by the front end 210 of wedge shape, pass ground connection via hole 304 after, the back-off 208 of pin 204 catches on the outer rim that pin inserts the offside ground connection via hole 304 of a side, and, be grounded and fix back-off 208 and the 30 bottom tin-coated copper layer welding of circuit plate body.
After making things convenient for holding section 10 to snap in coaxial cable 40, its center conductor 402 docks smoothly with microstrip line 302, slot to make way 306 is offered in circuit plate body 30 and holding section 10 corresponding positions, when the coaxial cable weld fixture apparatus was connected with printed circuit board (PCB), the cover shape member of holding section 10 partly sank to this slot to make way 306.
As shown in Figure 6, the schematic diagram for coaxial cable 40 is connected with printed circuit board (PCB) by above-mentioned weld fixture apparatus.Since with coaxial cable 40 with before printed circuit board (PCB) is connected, this weld fixture apparatus is fixedly connected in printed circuit board (PCB), therefore when implementing welding, coaxial cable 40 is removed overcoat 408, expose its screen 406 successively, insulating barrier 404 and center conductor 402 (in conjunction with Fig. 5), the part that coats screen 406 is embedded holding section 10 by opening 102, elasticity and opening by cover shape member, screen 406 can be encircled chucking, overlap the shape member simultaneously and partly sink to slot to make way 306, center conductor 402 is just in time docked with microstrip line 302, the operator only needs scolding tin is added center conductor 402 and the junction of microstrip line 302 and opening 102 places of holding section 10 this moment, implements welding at above-mentioned two places.
As shown in Figure 7, be the printed circuit board (PCB) rear view.Holding section 10 parts sink to slot to make way 306, the ground connection via hole 304 of slot to make way 306 both sides and pin 204 welding.
