Description
Technical field
A kind of inexpensive optocoupler is the utility model is related to, belongs to photovoltaic applications technical field.
Background technology
Liquid level majority use liquid level tester in oilfield test oil well casing annular space, liquid level letter used by this tester
Number filter and amplification plate need to be used, the amplification board automatically adjusts gain amplifier using optocoupler.The most uses of optocoupler purchased at present
The photo resistance of straight cutting and the light emitting diode of straight cutting, due to straight cutting LED welding be difficult to control diode with it is photosensitive
The distance between resistance, therefore the optocoupler made, its output resistance is widely different in the case of identical control source, should for the later stage
With hiding some dangers for, it is difficult that debugging is qualified in debugging process at the scene, debug time is added, so as to influence oil field liquid level tester
Batch production.
Utility model content
The purpose of this utility model is, there is provided a kind of inexpensive optocoupler.Using wiring board thickness ensure diode with
The distance between photo resistance, to reduce welding requirements and assembly and adjustment difficulty, the practicality of optocoupler is improved, solves in-site installation
Debug the problem of difficult.
The technical solution of the utility model：
A kind of inexpensive optocoupler, including wiring board, wiring board center are provided with unthreaded hole, and the wiring board two sides of unthreaded hole both sides is all provided with
There is pad, pad is connected with golden finger；Paster photo resistance, the weldering of wiring board another side are welded with the pad of wiring board one side
Patch light-emitting diode is welded with disk.
In foregoing inexpensive optocoupler, the golden finger for being welded with patch light-emitting diode one side is optocoupler input.
In foregoing inexpensive optocoupler, the golden finger for being welded with paster photo resistance one side is optocoupler output.
Compared with prior art, the utility model, only need to be by paster in assembling by the improvement to optocoupler welding manner
Component is welded on specified location, it is not necessary to adjust the distance of two kinds of SMD components, so as to reduce welding requirements and
Assembly and adjustment difficulty, improve the practicality of optocoupler and solve the problems, such as site installation test difficulty.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram after being completed；
Fig. 3 is the schematic diagram at Fig. 2 back sides.
In figure：The photo resistance of 1- pasters, 2- wiring boards, 3- patch light-emitting diodes, 4- pads, 5- golden fingers, 6- unthreaded holes,
7- embedding grooves, 8- pins.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
A kind of inexpensive optocoupler, as Figure 1-3, including wiring board 2, the center of wiring board 2 are provided with unthreaded hole 6, the both sides of unthreaded hole 6
Wiring board two sides be equipped with pad 4, pad 4 is connected with golden finger 5；It is photosensitive that paster is welded with the pad 4 of the one side of wiring board 2
Resistance 1, patch light-emitting diode 3 is welded with the pad 4 of the another side of wiring board 2.It is welded with the one side of patch light-emitting diode 3
Golden finger is optocoupler input.The golden finger for being welded with the one side of paster photo resistance 1 is optocoupler output.
Embodiment
This example as Figure 1-3, when specifically making, first processing line plate 2, an and unthreaded hole 6 is bored in the center of assist side 2；
Then pad 4 and golden finger 5 are processed in the both sides of unthreaded hole 6；The two pins 8 of paster photo resistance 1 are welded into assist side 2 wherein again
On pad 4 simultaneously, on pad 4 that the two pins 8 of patch light-emitting diode 3 are welded to the another side of assist side 2；It is welded with patch
The golden finger of the one side of piece light emitting diode 3 is as optocoupler input.The golden finger of the one side of paster photo resistance 1 is welded with as light
Coupling output end.During welding, patch light-emitting diode 3 and paster photo resistance 1 must be close to circuit plate weld, pass through wiring board
The distance between 2 thickness control patch light-emitting diode 3 and paster photo resistance 1, so as to ensure in identical control source feelings
The uniformity of its output resistance under condition, improve the accuracy of test.
This example is mainly the improvement to optocoupler welding manner, and wiring board is connected up using top surface and bottom surface, and there is pad on two sides
With extraction golden finger, wherein there is two inputs for being used for optocoupler in four golden fingers, two other is used for the output of optocoupler.Will patch
The top surface of assist side is welded in piece photo resistance, and patch light-emitting diode is welded to the bottom surface of assist side.The utility model
Easily make, low manufacture cost, welding and field adjustable are all very convenient in factory.This optocoupler is ingenious true using the thickness of printed board
The distance of two kinds of SMD components is protected, the required distance of two kinds of SMD components is not adjusted, solves welding difficulty well
The problem of with field adjustable difficulty.
