Description
Technical field
The utility model belongs to the technical field of pcb board encapsulation, specifically, relates to the encapsulating structure of a kind of single connector and pcb board.
Background technology
Along with the development of electron trade, especially the developing rapidly of electronic device technology, proposes more and more higher requirement to the integrated level of current pcb board.
In the design of PCB, consider the needs in overall structure space, standardization, the commonality of PCB need, usually the circuit unit with certain function is made an independent PCB(1), according to the needs of integrated circuit again using PCB (1) as a components and parts plug-in unit to another one PCB (2) above, the electrical connection of PCB (1) and PCB (2), this just needs a kind of single connector both to be connected.
This will produce a problem: in actual production process, when the encapsulation aperture of single connector arranges less, PCB (1) can be caused to be difficult to plug-in unit on PCB (2), and be difficult to keep in repair and be inconvenient to change; And single connector encapsulation aperture is when arranging larger, because PCB (1) is fitted with components and parts above equally, under the effect of itself gravity, PCB (1) easily tilts, and easily damages PCB when crossing tin stove, has certain fraction defective.And single connector apparatus itself also exists certain tolerance, therefore in the rational magnitude range in single connector encapsulation aperture, be difficult to address this problem.
Summary of the invention
The utility model overcomes shortcoming of the prior art, provide the encapsulating structure of a kind of single connector and pcb board, its problem effectively solving the difficult plug-in unit of combined pcb board and easily tilt, two pcb board fixations, reduce PCB fraction defective and processing cost.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The encapsulating structure of a kind of single connector and pcb board, single connector is provided with some parallel pins, the corresponding pin of pcb board is provided with some encapsulated holes, the aperture being positioned at the encapsulated holes of both sides is greater than diameter 1 to the 3mil of pin, the aperture of middle encapsulated holes is greater than diameter 5 to the 12mil of pin, and the encapsulated holes of pcb board both sides and corresponding pin are closely cooperated.
Further, the diameter of pin is 33.07mil-35.04mil, and the aperture being positioned at the encapsulated holes of both sides is 36mil.
Further, the aperture of middle encapsulated holes is 40mil.
Further, the aperture of middle encapsulated holes is 45mil.
Further, pin comprises straight-bar type pin and folding type pin, and straight-bar type pin, through after single connector, is bent to form folding type pin, straight-bar type pin and folding type pin perpendicular.
Compared with prior art, the beneficial effects of the utility model are:
The encapsulating structure of a kind of single connector described in the utility model and pcb board, the aperture being positioned at the encapsulated holes of pcb board both sides is less than the aperture in intermediate package hole, the encapsulated holes of pcb board both sides and corresponding single connector pin are closely cooperated, pcb board is not easy, simultaneously, the easier grafting of pcb board and dismounting, for ease of maintenaince and change, adopt this design reduces and produce fraction defective and processing cost.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of a kind of single connector described in the utility model;
Fig. 2 is the left view of the utility model Fig. 1.
Wherein, 1---single connector;
2---straight-bar type pin;
3---folding type pin.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment 1
The encapsulating structure of a kind of single connector described in the utility model and pcb board, its circuit unit (as drive circuit) with certain function is designed to one piece of independently PCB (1), according to the needs of integrated circuit function again using PCB (1) as a components and parts plug-in unit to another one PCB (2) above, the electrical connection between them adopts single connector 1 to connect.
Consult Fig. 1,2, the pin of single connector 1 comprises straight-bar type pin two and folding type pin 3, straight-bar type pin two is through after single connector 1, be bent to form folding type pin 3, straight-bar type pin two and folding type pin 3 perpendicular, straight-bar type pin two and folding type pin 3 are welded in two pcb boards respectively, it is between 0.84mm-0.89mm that pin size can find its mean value according to specifications, if be converted into mil, according to reduction formula 1mm=39.37mil, the size of this single connector pin is 33.07mil-35.04mil.
In the design ap-plication of reality, consider the tolerance of device itself, with reference to the encapsulation specification of device, 40mil or 45mil that be encapsulated as of this single connector 1 is rational, but no matter be 40mil(1.016mm in actual production) or 45mil(1.143mm) all easily cause PCB (1) assembly to tilt, when pcb board crosses tin stove, PCB is caused to damage, and after encapsulation is changed to 36mil (0.9144mm), PCB (1) although assembly can not produce loosening tilt problem, but can cause difficult plug-in unit and be inconvenient to the problem of keeping in repair.
Therefore, the aperture, both sides of single connector 1 changes to 36mil (0.9144mm), solves PCB (1) assembly and loosens easy tilt problem; Median pore radius still remains 40mil(1.016mm), solve the difficult plug-in unit of PCB (1) assembly and be difficult to maintenance problem.Such design reduces simultaneously produces fraction defective and processing cost.
Embodiment 2
The present embodiment is roughly the same with embodiment 1 technical scheme, and something in common repeats no more, and its difference is:
Median pore radius adopts 45mil(1.143mm), the aperture, both sides of single connector 1 is the same with embodiment 1 adopts 36mil (0.9144mm).
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
