Embodiment
For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Fig. 1 to Fig. 3 is the structural representation of the adjustable feeler gauge of the utility model, as shown in Figure 1 to Figure 3, the utility model proposes a kind of adjustable feeler gauge 300 measured for electric clearance and creepage distance, adjustable feeler gauge 300 comprises at least two parallel bodies 310 overlapped and the handle 320 be connected with body 310.The number of this body 310 is generally 5 to 20.Body 310 comprises for carrying out measurement section 311 that electric clearance or creepage distance measure and lengthening part 312, be rotatably connected by the first rotating shaft 313 between measurement section 311 and lengthening part 312, one end that lengthening part 312 is not connected with measurement section 311 is rotatably connected by the second rotating shaft 314 with handle 320.As shown in Figure 1, the width of measurement section 311 corresponding on the plurality of body 310 is different, for measuring different electric clearances and creepage distance.Measurement section 311 can be bar shaped sheet or bar shaped bar-shaped.
As shown in Figure 2, the U-shaped structure of handle 320, preferably adopts stalloy bending forming.Handle 320 comprises two ends, and two ends are provided with symmetrical through hole; One end that the lengthening part 312 of body 310 is not connected with measurement section 311 is provided with perforation, is equipped with the second rotating shaft 314 between the perforation of through hole and body 310.In the embodiment shown in Figure 2, the second rotating shaft 314 is set screw, and it comprises the adjusting portion 315 of the tightness for regulating body 310 and handle 320.Concrete, the rotatable engagement of set screw and nut is adopted to make body 310 adjustable with the tightness of handle 320 in the embodiment shown in Figure 2, thus can relative angle between fixed handle 320 and body 310, more be convenient to measure, and time in the U-shaped space that the body 310 of feeler gauge 300 is accommodated in handle 320, can make it not deviate from handle 320 by fixed body 310.As shown in Figure 3, the U-shaped structure of handle 320, when not measuring, by body 310 folding storage of feeler gauge 300 in the U-shaped space of handle 320, can avoid the measurement section 311 of feeler gauge 300 to damage, affects measuring accuracy.Obviously, this handle 320 also can adopt other conventional handle of non-U-shaped structure.
As shown in Figure 2, be also provided with pad 330 between two adjacent bodies 310, pad 330 is arranged in the second rotating shaft 314.Concrete, because the measurement section 311 of body 310 and lengthening part 312 are not one-body molded, but connected by the first rotating shaft 313.Therefore measurement section and 311 and lengthening part 312 on the length direction of the second rotating shaft 314, there is coincidence, and the first rotating shaft 313 also will take certain space.Therefore, pad 330 is set between adjacent two bodies 310 two bodies 310 can be avoided mutually to interfere, the particularly interference of the measurement section 311 of adjacent two bodies 310.
In addition, the lengthening part 312 of body 310 and the first rotating shaft 313 of measurement section 311 also can adopt the plus screw of adjusting elasticity, the angle between lengthening part 312 and measurement section 311 are fixed or adjustable, thus are more convenient to measure.Obviously, the pin feature that other also can be adopted to have locking function replaces plus screw as the first rotating shaft 312 and the second rotating shaft 314.Preferably, the first rotating shaft 313 and the second rotating shaft 314 also all can adopt plus screw.
When carrying out electric clearance to product and creepage distance measures, for the place that some adopts existing feeler gauge to measure, such as UUT is positioned at dark chamber portion, by the adjustment body 310 of gauge and the angle of handle 320 and regulate angle between the lengthening part 312 of body 310 and measurement section 311, reach and need not dismantle or destroy electric product structure, with regard to the direct effect measured measuring point, thus significantly improve measurement efficiency and reduce the test sample proportion of goods damageds.After angular adjustment, can taking to lock the plus screw as the first rotating shaft 313 and the second rotating shaft 314, thus fix the angle of body 310 and handle 320 and the angle between lengthening part 312 and measurement section 311, avoiding rocking of when measuring body.Obviously, the pin feature that other also can be adopted to have locking function replaces plus screw as the first rotating shaft 312 and the second rotating shaft 314.Wherein, this body 310 is stainless steel material.
Fig. 4 is the schematic diagram adopting the adjustable feeler gauge in Fig. 1 to test the electric clearance between two of electronic product inside live components.During for the opening 201 on the housing of this electronic product 200 not just to its element under test, existing common craspedodrome gauge is adopted to measure, and adopt adjustable feeler gauge 300 of the present utility model, after regulating angle, then can the electric clearance between element 202 and 203 be measured, thus whether the electric clearance between decision element 202 and 203 is greater than regulation requirement.And need not dismantle or destroy electric product structure, with regard to the direct effect measured measuring point, thus significantly improve measurement efficiency and reduce the test sample proportion of goods damageds.
Preferably, handle 320 can by bar shaped stainless steel substrates bending forming or injection mo(u)lding.And body 310 also can adopt stainless steel or other conductive metallic materials to make, by whether conducting checks whether measurement section 311 has touched unit under test.
The above; for the person of ordinary skill of the art; can make other various corresponding change and distortion according to the technical solution of the utility model and technical conceive, and all these change and be out of shape the protection domain that all should belong to the utility model claim.
