Abstract
The utility model discloses an electrical connection structure of a circuit board. The electrical connection structure comprises a first circuit board and a second circuit board which are electrically connected with each other, wherein the electrical connection between the first and the second circuit boards is implemented through a flexible circuit board. Since the electrical connection between the circuit boards is implemented through the flexible circuit board, compared with the coaxial cable and the coaxial cable connector in the prior art, the flexible circuit board is lighter and the weight of the whole machine is reduced after assembly. The flexible circuit board has good flexibility, and is bent or folded freely, which helps to save the assembly space during the assembly of the entire machine. Besides, the flexible circuit board is adopted, so as to omit the use of the connector of the coaxial cables, achieve the signal transfer through the holes and remain the signal integrity.
Description
Technical field
The utility model relates to the electronic communication field, more particularly, relates to a kind of electric connection structure of circuit board.
Background technology
At present, coaxial cable is widely used in being electrically connected in the electronic circuit assembling, in existing package assembly, adopt following pattern mostly: as shown in fig. 1, on one first pcb board 91, be installed with coaxial cable connector 911, set firmly same coaxial cable connector 921 on one second pcb board 92, realize being electrically connected between first pcb board 91 and second pcb board 92 on coaxial cable connector 911 and the coaxial cable connector 921 thereby be inserted in respectively by two ends with coaxial cable 93.Adopt coaxial wire 93 to finish connection, though more convenient, also have following problem: 1, coaxial cable is heavier, and usage quantity is more can to increase main frame weight; 2, coaxial bending and bending property are relatively poor, need to reserve in the complete machine structure design and carry out cable routing than large space, have increased the main frame volume; 3, need to use special connector, connector is bigger to the loss of signal, and transmission performance is poor.
The utility model content
Technical problem to be solved in the utility model is to provide the electric connection structure of a kind of in light weight, good reliability, circuit board easy to assembly.
For solving the problems of the technologies described above, the technical solution of the utility model is: the electric connection structure that a kind of circuit board is provided, the first circuit board and the second circuit board that comprise electrical connection are realized being electrically connected by a flexible PCB between described first circuit board and the second circuit board.
Particularly, described flexible PCB comprises the insulating body layer, is contained in the insulating body layer and in insulating body layer two ends and stretches out and the conductor that is connected with described first circuit board and second circuit board respectively, the metal screen layer of wrap insulate body layer and the diaphragm that is covered in metal screen layer upper surface and lower surface.
Particularly, be provided with through hole in the described insulating body layer, described conductor is the lead that runs through described through hole.
Perhaps, be provided with through hole in the described insulating body layer, described conductor is for applying the coat of metal of described through hole.
Further, be equipped with on described first circuit board and the second circuit board and can hold described flexible PCB two ends and insert fixing mounting groove.
Utilize flexible PCB to realize electrical connection between the circuit board in the utility model, the coaxial cable in and coaxial cable connector compared to prior art, flexible PCB is lighter, can alleviate complete machine weight after installing; Again because of the flexible PCB flexibility is good, but free bend, folding can be saved a large amount of installing spaces in whole machine installation; Adopt flexible PCB to save the connector of coaxial cable simultaneously, realize signal converting, kept the integrality of signal by the hole.

Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 2, the electric connection structure of a kind of circuit board that provides for the utility model.The electric connection structure of described circuit board comprises the first circuit board 1 and the second circuit board 2 of electrical connection, realizes being electrically connected by a flexible PCB 3 between described first circuit board 1 and the second circuit board 2.Utilize flexible PCB 3 to realize electrical connection between the circuit board in the utility model, the coaxial cable in and coaxial cable connector compared to prior art, flexible PCB is 3 lighter, can alleviate complete machine weight after installing; Again because of flexible PCB 3 is flexible good, but free bend, folding can be saved a large amount of installing spaces in whole machine installation; Adopt flexible PCB 3 to save the connector of coaxial cable simultaneously, realize signal converting, kept the integrality of signal by the hole.
Particularly; with reference to Fig. 3, Fig. 4, described flexible PCB 3 comprises insulating body layer 31, is contained in the insulating body layer 31 and the conductor 32 that stretches out in insulating body layer 31 two ends and be connected with first circuit board 1 and second circuit board 2 respectively, the metal screen layer 33 of wrap insulate body layer 31 and the diaphragm 34 that is covered in metal screen layer 33 upper surfaces and lower surface.Because metal screen layer 33 left and right end faces are the left and right end face of flexible circuit board 3, same as the prior artly when making to be coated with spreading mass, so metal screen layer 33 left and right end faces need not keep film 34.Described insulating body layer 31 is to be a thin plate of base material with polyimides or polyester film, and above-mentioned base material is in light weight, thin thickness, and flexible good, have too with the flexible PCB 3 of its making in light weight, thin thickness, and flexible good characteristics.Be provided with the through hole (not shown) in the described insulating body layer 31, described conductor 32 is for running through the lead 321 of described through hole.Certainly, described conductor 32 also can be for being coated on the coat of metal of described through hole.
With reference to Fig. 3, be equipped with on described first circuit board 1 and the second circuit board 2 and can hold fixing mounting groove 11 and the mounting groove 21 of described flexible PCB 3 two ends insertion.During installation, the two ends of flexible PCB 3 are inserted in mounting groove 11 and the mounting groove 21, the conductors 32 that stretch out by insulating body layer 31 two ends in this moment flexible PCB 3 respectively with the internal circuit conducting of first circuit board 1 and second circuit board 2, thereby realize electrical connection between the two.In the present embodiment, directly realize signal converting, saved electric connector, when reducing cost, also guaranteed the complete of signal by mounting groove 11 and mounting groove 21.Because the thin plate of insulating body layer 31 for having good flexibility of flexible PCB 3; can freely fold when mounted, crooked; not limited by the spacing of circuit board; install more convenient; simultaneously, in the metal screen layer 33 of insulating body layer 31 outer wrap, can effectively stop the interference of external environment to transmission signals; improved signal transmission quality, and the diaphragm 34 that is covered in metal screen layer 33 upper surfaces and lower surface makes metal screen layer 33 obtain to have the appearance of ornamental and protectiveness.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
