Detailed description of the invention
Below in conjunction with the accompanying drawings structural principle of the present utility model and operation principle are described in more detail.
As shown in Figure 1 and Figure 2, one of the present utility model easy radio-frequency cable component bend test device, mainly by
Fixed plate 1, rotary handle 2, mandrel 3,4, two bending axis 5 of installing plate form, and described fixed plate 1 is by mandrel 3 and rotation hands
Handle 2 connects, and installing plate 4 is arranged on rotary handle 2.
Fixed plate 1 may be installed on bench vice or uses in other any occasion, by fixed plate 1, bend test fixture is solid
Fixed.
As it is shown on figure 3, fixed plate 1 is provided with a multiple word translot 1-1, two bending axis 5 select the position of correspondence, pass through
One word translot 1-1, is fixed in fixed plate 1 with nut.
As it is shown in figure 5, two bending axis 5 afterbodys are provided with thread spindle 5-1.Bending axis 5 is provided with movable bayonet lock 5-2, anti-
Only in cable bend process of the test, swing is excessive.
The outside dimension of bending axis 5 is the size of the minimum dynamic bending diameter of cable.
Distance between two bending axis 5 is than big 0.5mm～1mm of maximum outside diameter size of cable.
Rotary handle 2 can realize clockwise or counterclockwise, as shown in Figure 4, rotary handle 2 is provided with chute 2-
1, can be according to the position adjustments length of bending.
As shown in Figure 6, installing plate 4 is provided with adapter 4-1, according to the model of radio-frequency cable component two terminal adapter, choosing
Select the adapter matched to be fixed on installing plate 4.
Such as: a radio-frequency cable component, a diameter of φ 4.1mm of cable, it is contact pin form that two ends connect inner wire
SMA type adapter, it is desirable to by the regulation of 4.5.6 in GJB1215A-2005, applies 5N power vertically downward, is curved test.
As it is shown in fig. 7, according to the minimum dynamic bending radius size of cable, two bending axis 5 selecting radius to be 40mm
By the word translot in fixed plate 1, being fixed in fixed plate 1 with nut, the distance of two bending axis 5 is less times greater than cable
Maximum outside diameter, is set as 5mm.
