Including the needle body, its characterized in that: the needle body is provided with elasticity plug -in section with circuit board connection's one end, and elasticity plug -in section was used for the principal columns of a hall to peg graft in the spliced eye of circuit board. The utility model discloses need not the welding and connect reliably, needle body and the direct crimping of PCB, area of contact is firm, and the improvement has the complexity of cubic needle use now to can solve the recessive problems of function such as rosin joint, improve the life of product, reduce manufacturing cost.
Description
Technical field
This utility model relates to electronics connection area, a kind of is widely used in wiring board communication, wiring board flake four policy that electric current connects.
Background technology
Four policies are mainly used in electronic circuit board connector field, and product structure is the most wired to plate, Line To Line, and plate, to plate connected mode, can meet the connection scheme of various disconnecting circuit.Enhance the functional and reliability of electronic circuit, electric current, communication.For Product Process；Tradition four policies are inserted after pcb boards, need to be connected on pcb board by wave-soldering or SMT machine welding, could constitute and be connected between contact pin with wiring board, and therefore the product of this structure exists drawback: (1) complex manufacturing, adds production cost；(2) welding position uses for a long time or link position heating is easily caused sealing-off, make to be connected between four policies and wiring board instability, cause the problems such as loose contact, so that the use value of product can not effectively be embodied, reduce value and the service life of product；<3>during welding, high temperature melting stannum can destroy original electrodeposited coating, gets rusty, affect contact performance and function after accelerating conductive medium oxidation.(4) during maintenance, need first welding position to be carried out hot melt process, be not easy to client maintenance.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, there is provided a kind of without welding and connecting reliable wiring board flake four policy, needle body directly crimps with PCB, contact area consolidates, improve existing four policies and use the complexity of process, and can solve the problem that the function recessiveness problems such as rosin joint, improve the service life of product, reduce production cost.
The technical scheme realizing above-mentioned purpose is: wiring board flake four policy, including needle body, it is characterised in that: one end that described needle body is connected with wiring board is provided with elastic inserting section, and elastic inserting section was used for the principal columns of a hall and is plugged in the spliced eye of wiring board.
Described elastic inserting section is tapered to one end of the spliced eye grafting of wiring board, the outer wall lateral symmetry of described elastic inserting section is provided with the V-arrangement elongated slot that big opening end is outside, elastic inserting section is divided into two cross sections being oppositely arranged in fan-shaped elastic component by two V-arrangement elongated slots, dislocation lap joint between two elastic components, spring seam is formed between the lap position of two elastic components, the radial force applied spring seam by the spliced eye of wiring board, makes accurate laminating between periphery and the spliced eye of wiring board of two elastic components.
As further optimization of the present utility model, the two ends of described needle body are the most tapered, facilitate grafting, improve production efficiency.
Compared with prior art, this utility model has the advantages that
1, it has been designed to taper due to elastic inserting section to one end of the spliced eye grafting of wiring board, it is simple to client is installed, and improves production efficiency, guarantees quality.
2, after in the spliced eye of elastic inserting section insertion wiring board, spliced eye two elastic components compressed radially inward of wiring board, two elastic components can produce elastically-deformable effect along spring seam direction after being squeezed, and makes elastic inserting section cross the principal columns of a hall and is plugged in the spliced eye of wiring board.
3, two elastic component cross sections are sector, curved of the lateral surface of two elastic components, make elastic grafting will not pierce through Copper Foil by force when inserting in the spliced eye of wiring board, can protect contact surface.
4, when this utility model inserts the spliced eye of wiring board, the inwall of spliced eye will not because of after extruding Copper Foil serious or impaired, needle body and Copper Foil medial wall consolidate and are connected.
5, after wiring board extracts four policies, two i.e. hollows of elastic component, to the state before inserting, can be extracted with circular insertion.
6, the spring seam stress between two elastic components has the function of automatic telescopic, and recycling does not have the most elastic impaired, and elastic strength meets design requirement.
7, forming whole between this utility model and the spliced eye of wiring board to contact rather than a single contact point, contact impedance is little, and cross-sectional area is big, current loss and signal height frequency equalization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 A A to sectional view；
Fig. 3 is use state diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings structure of the present utility model and operation principle are described further:
As shown in Figure 1, 2, this utility model includes needle body 1, and the two ends of needle body 1 are the most tapered.One end that needle body 1 is connected with wiring board is provided with elastic inserting section 2, and elastic inserting section 2 was used for the principal columns of a hall and is plugged in the spliced eye of wiring board.
Elastic inserting section 2 is tapered to one end of spliced eye 6 grafting of wiring board 5, the outer wall lateral symmetry of elastic inserting section 2 is provided with the V-arrangement elongated slot 3 that big opening end is outside, elastic inserting section 2 is divided into two cross sections being oppositely arranged in fan-shaped elastic component 7 by two V-arrangement elongated slots 3, dislocation lap joint between two elastic components 7, spring seam 4 is formed between the lap position of two elastic components 7, by the spliced eye of the wiring board radial force to spring seam 4 applying, make accurate laminating between periphery and the spliced eye of wiring board of two elastic components 7.
Needle body 1 can not have sharp dead angle, it is impossible to destroys electrodeposited coating and the Copper Foil of wiring board.
As shown in Figure 3, when this utility model uses, elastic inserting section 2 is inserted in the spliced eye 6 of wiring board 5, spring seam 4 between the bottom land of spliced eye 6 two V-arrangement elongated slots 3 compressed radially inward of wiring board 5, the spring of elastic inserting section 2 stitches 4 two side portions and dislocation occurs and pastes friction mutually, produce outside tension force, make elastic inserting section 2 cross the principal columns of a hall and be plugged in the spliced eye 6 of wiring board 5, eliminate welding sequence of the prior art.
This utility model hinge structure has an obvious advantage:
1, product uses press-fit technique, substitutes conventional bonding technique, and packaging efficiency is fast, and low cost is equipped.
2, destroy electrodeposited coating and insulation plastic cement after avoiding prior art weld technique instantaneous high-temperature to be heated completely, cause diminishing with four policy chucking powers.
3, avoid solder at high-temperature steam process leaves residuals, affect product connective stability.
4, product is without welding, therefore need not process cold welding joint or rosin joint and cause short circuit.
5, need not wiring board is carried out after installing, reduce operation.
6, readily replaceable, low cost is keeped in repair.
And plug performance of the present utility model is reliable, and concrete data see table:
Embodiment is not construed as the restriction to utility model, but any based on spirit improvements introduced of the present utility model, all should be within protection domain of the present utility model.
