[0002] During circuit board manufacturing, aluminum substrates need to undergo high-voltage resistance testing to ensure their insulation performance. Currently, batch testing is commonly used: a large substrate composed of multiple small aluminum substrates is manually fed into a testing machine.

[0031] When assembling the wires, the cover plate 7 is manually detached to expose the partitions 8, and then the lock rods 202 and the lock block 2 203 are detached, as Figure 6 and Figure 7As shown, the layers 91 are counted from bottom to top, the probes 6 are counted from the side close to the support block 208, and the locking rods 202 are counted from bottom to top. The other partitions 8 above the first row of partitions 8 are turned upward, and the partitions 8 are rotated around the pivot part 93, so that the first row of partitions 8 is exposed. Then, an electric wire is connected to a row of probes 6, and the electric wire is laid on the upper side of the first row of partitions 8 and passes through the groove two 95 of the first row of partitions 8, then passes through the groove one 92 on the locking block one 201, and then the locking rod 202 is inserted into the locking block one 201, so that the electric wire is limited in the groove one 92. Then, the second row of partitions 8 is turned back to the original position manually, and the end of the second row of partitions 8 away from the pivot part 93 is supported on the flange part 94 of the first row of partitions 8. At this time, the layers 91 are formed between the first row of partitions 8 and the second row of partitions 8, and the electric wire on the first row of probes 6 passes through the layers 91. Then, another electric wire is connected to the second row of probes 6, and the electric wire is laid on the upper side of the second row of partitions 8 and passes through the groove two 95 of the second row of partitions 8, then passes through the groove one 92 on the upper side of the first row of locking rods 202, and then the second row of locking rods 202 is inserted into the upper side of the first row of locking rods 202, so that the electric wire is limited in the corresponding groove one 92. Then, the third row of partitions 8 is turned back to the original position manually, and the end of the third row of partitions 8 away from the pivot part 93 is supported on the flange part 94 of the second row of partitions 8. At this time, the layers 91 are formed between the second row of partitions 8 and the third row of partitions 8, and the electric wire on the second row of probes 6 passes through the layers 91. In this way, the electric wire installation operation is completed, and after the last row of electric wires is installed, the locking block two 203 is inserted into the uppermost locking rod 202, and then the locking block one 201, the locking rod 202 and the locking block two 203 are fixed by bolts. Then, the cover plate 7 is installed back to the original position, and the assembly operation is completed. Then, the ends of all the electric wires are connected to the external testing machine. During testing, the large-size substrate composed of multiple small aluminum substrates is placed on the receiving plate 2, the telescopic cylinder 4 is started, and the box body 5 and the parts thereon are driven to move downward, so that the probes 6 move downward to contact the test position of the aluminum substrate. At this time, the external testing machine discharges the aluminum substrate through the electric wires and the probes 6, so as to perform voltage resistance test on the aluminum substrate batch.

[0032] When the electric wire is short-circuited and broken, and the like, assuming that the electric wire on the third row of probes 6 is faulty, the cover plate 7 is manually opened, and then the other partitions 8 above the third row of partitions 8 are turned up, so that the third row of partitions 8 is exposed, so that the third row of probes 6 and the electric wire thereon are exposed, at this time, the corresponding electric wire end is manually detached from the probe 6, and then the other end of the electric wire is pulled, so that the electric wire is pulled out of the groove two 95 and the groove one 92, and then the electric wire is detached, then the end of the new electric wire is connected in the external testing machine, at this time, without detaching the lock block one 201, the lock rod 202 and the lock block two 203, the other end of the electric wire is directly inserted through the corresponding groove one 92, and then through the corresponding groove two 95, so that it moves to the upper side of the third row of partitions 8, and then the electric wire is connected to the corresponding probe 6, and then the other partitions 8 above the third row of partitions 8 are turned back to the original position, and then the cover plate 7 is installed back to the original position, the electric wire replacement operation is completed; in use, the partitions 8 with increasing width are used to space the electric wires, when the electric wire is faulty, the position of the faulty electric wire can be quickly determined and taken out, avoiding the problems of difficult positioning and replacement of the faulty electric wire due to the complex existing device wire harness, and facilitating the convenience of manual operation.

[0033] During the detection process, the telescopic cylinder 4 drives the box body 5 to reciprocate up and down, that is, each electric wire is limited through the groove one 92, the electric wires outside the box body 5 are long-term shaken and still have the phenomenon of crossing and overlapping, during the replacement of the electric wire, the partition 8 needs to be turned up by the worker, at this time, the partition 8 will drive the electric wire to move together, so as to pull the electric wire outside the box body 5 to the inside, if the electric wires outside the box body 5 are distributed in a crossed and overlapped manner, the resistance received by the electric wire when pulled will be greatly increased, causing the partition 8 to be difficult to be normally opened, therefore, before the replacement of the electric wire, the L-shaped block 206 is manually actuated to move away from the lock block one 201, so that the L-shaped block 206 stops fixing the lock block one 201, then the lock block one 201 is manually pulled to move away from the box body 5, the lock block one 201 drives the lock rod 202 and the lock block two 203 to move at the same time, and stretches the multi-stage telescopic rod 205, so that the lock block one 201, the lock rod 202 and the lock block two 203 are matched to comb and disperse the crossed electric wires through the groove one 92, then the lock block one 201, the lock rod 202 and the lock block two 203 are pushed back to the original position as a whole, and the L-shaped block 206 is used to fix the lock block one 201 again, then the replacement of the electric wire is performed, when the partition 8 is turned up by the worker, the partition 8 drives the combed and dispersed electric wires to move to the inside of the box body 5, and no jamming phenomenon occurs, after the replacement is completed, the electric wire is adaptively pulled out to the outside of the box body 5 when the partition 8 is turned back to the original position by the worker, so as to ensure that the electric wires distributed in the inside of the box body 5 are in a straight state; in use, the lock block one 201, the lock rod 202 and the lock block two 203 for limiting the electric wire can also comb and disperse the electric wires outside the box body 5, so that when the partition 8 is turned up, the partition 8 can drive the combed and dispersed electric wires to move to the inside of the box body 5, and no jamming phenomenon occurs.

[0034] Embodiment 2, on the basis of embodiment 1, as shown in Figure 9 and Figure 10 Further comprising rubber blocks 207; each partition plate 8 is provided with a plurality of recesses three 96, and the recesses three 96 are aligned with the corresponding probes 6; each partition plate 8 is fixedly connected with a plurality of rubber blocks 207, and the rubber blocks 207 are located inside the corresponding recesses three 96, and the rubber blocks 207 are used to fix the wires.

[0035] Each recess three 96 is provided with a plurality of inclined surfaces 97 on both sides of the opening, and the inclined surfaces 97 are used to guide the wires, so that the wires are more easily clamped inside the rubber blocks 207.

[0036] The cover plate 7 is provided with a handle, and the cover plate 7 is opened by the handle, so that the force is more convenient.

[0037] During the replacement process, the partition plate 8 in the overturning process will exert a friction force on the wires thereon, and the friction force acts on the connection position of the wires and the probes 6, thereby interfering with the connection stability of the wires and the probes 6, and thereby interfering with the subsequent test operation, therefore, the rubber blocks 207 are arranged on the partition plate 8, when the wires are installed, the wire end is fixed on the probe 6, then the wire is clamped into the rubber block 207, and the wire is placed on the upper side of the partition plate 8, at this time, the rubber block 207 is compressed and reliably limited by the elastic deformation thereof, and during the overturning process of the partition plate 8, since the wires are effectively fixed at the rubber blocks 207, the friction force generated by the partition plate 8 on the wires mainly acts on the compression area of the rubber blocks 207, rather than directly transmitted to the connection point of the wires and the probes 6, and the influence of the friction force is absorbed and dispersed by the rubber blocks 207, thereby avoiding the problem that the connection position is loosened due to the direct force.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited to the protection scope of the present application, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
