Description

Technical Field

[0002] Surge testing is usually performed to evaluate the performance and robustness of electrical or electronic equipment when subjected to transient overvoltage (surge) shocks. During the test, in order to simulate the real electrical environment, an electromagnetic disturbance module (usually used to simulate electromagnetic interference) and climate control equipment (such as a temperature and humidity environment chamber) are used. During the surge test, the electromagnetic disturbance module is placed outside the temperature and humidity module, connected to the coupling decoupling network CDN through a high-voltage line, and the coupling decoupling network CDN and the device under test are placed in the temperature and humidity environment chamber.

[0003] The coupling decoupling network CDN and other devices need to be connected through high-voltage insulating joints. However, the existing high-voltage insulating joints are affected by temperature and humidity in the temperature and humidity environment box, which will produce the following disadvantages: In a high-temperature environment, the insulating material may soften, resulting in a decrease in mechanical strength and voltage resistance. Long-term high temperature may cause the insulating material to age, deform or even crack, directly affecting the insulation performance of the insulating joint. In a high-humidity environment, the insulating material may absorb moisture, causing the insulation performance to deteriorate, and may even form a conductive path, resulting in leakage or short circuit.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1

[0034] Reference Figure 1 , which is the first embodiment of the present invention, provides a high-voltage insulation connection test box for a high-temperature and high-humidity environment, which includes a cooling unit 100, including a placement box 101 and a cooling tube 102, and the placement box 101 has at least one group of installation spaces A equally spaced apart, and the cooling tube 102 is placed in the placement box 101.

[0035] There is airflow flowing in the cooling pipe 102, and the airflow temperature is lower than the temperature in the temperature and humidity environment box, and can be the external environment temperature.

[0036] The connector unit 200 includes a male connector 201 and a female connector 202 . The male connector 201 and the female connector 202 are detachably connected. After being fixed, the male connector 201 and the female connector 202 can be matched and placed in the installation space A and connected and fixed to the cooling pipes 102 on both sides.

[0037] The cooling tube 102 is installed horizontally in the placement box 101 , the installation space A is located between two adjacent cooling tubes 102 , and the joint unit 200 is clamped in the installation space A as a whole.

[0038] Furthermore, the male connector 201 and the female connector 202 are both cylindrical in structure and can be plugged into each other and rotated and fixed, and the connecting wires on the coupling decoupling network CDN and the wires of other devices are connected and fixed through the male connector 201 and the female connector 202 .

[0039] During use, the tester installs multiple sets of connector units 200 from above into the installation space A. During this process, the connector units 200 push the locking plates of the cooling tubes 102 to both sides. After the connector units 200 are installed in place, the locking plates of the cooling tubes 102 will reset and fix the connector units 200 to prevent the connector units 200 from shaking at will in the placement box 101.

[0040] Furthermore, after the connector unit is fixed, the placement box 101 is closed, and air flows through the cooling tube 102, blowing toward the connection between the male connector 201 and the female connector 202 from both sides, thereby reducing the core temperature and improving the test stability.

[0041] Example 2

[0042] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the male head 201 includes a first fixed seat 201a and a first side arc wall 201b symmetrically fixed at one end edge thereof, and a first arc plate 201c is also fixed to the side wall of the first side arc wall 201b away from the first fixed seat 201a, and the first arc plates 201c on both sides are symmetrical about the center; a first detection head 201d is also fixed to the middle of the first fixed seat 201a.

[0043] The female head 202 includes a second fixed seat 202a and a second side arc wall 202b symmetrically fixed on one end edge thereof.

[0044] Furthermore, the structure of the first side arc wall 201b and the first arc plate 201c is "L" shaped, and the shape of the second side arc wall 202b and the second arc plate 202c is the same as the shape of the first side arc wall 201b and the first arc plate 201c.

[0045] A first slot 201a-1 is formed between the first arc plate 201c and the first fixed seat 201a, and a second slot 202a-1 is formed between the second arc plate 202c and the second fixed seat 202a. The first arc plate 201c and the second arc plate 202c can be complementarily plugged into the second slot 202a-1 and the first slot 201a-1 respectively.

[0046] During use, the male head 201 and the female head 202 are brought close to each other, and the first arc plate 201c is inserted into the female head 202 along the sliding gap between the adjacent second side arc wall 202b and the second arc plate 202c, and then the first fixing seat 201a is rotated to ensure that the first arc plate 201c is plugged into the second card slot 202a-1.

[0047] An embedded groove 201b-1 is provided in the first side arc wall 201b, and a filter plate 201b-2 is slidably engaged in the embedded groove 201b-1; a stabilizing slot 201b-1a is provided on the inner wall of the embedded groove 201b-1 near one end of the first arc plate 201c.

[0048] The stabilizing slot 201b-1a penetrates the arc-shaped inner wall of the first side arc wall 201b and slightly extends into the first arc plate 201c.

[0049] The filter plate 201b-2 includes a filter plate body 201b-2a, an arc-shaped connecting rod 201b-2b and a connecting block 201b-2c. The arc-shaped connecting rod 201b-2b is fixedly connected to the inner wall of one end of the filter plate body 201b-2a and extends to the outside of the filter plate body 201b-2a. The connecting block 201b-2c is fixed to the middle part of the side of the filter plate body 201b-2a away from the filter plate body 201b-2a. The filter plate body 201b-2a and the arc-shaped connecting rod 201b-2b can be slidably inserted into the embedded groove 201b-1 and the stabilizing groove 201b-1a respectively; a snap-on strip 201b-2c1 is also fixed to the bottom of the connecting block 201b-2c.

[0050] Among them, the filter plate body 201b-2a is provided with ventilation holes to facilitate heat dissipation.

[0051] During use, the filter plate body 201b-2a is entirely received in the embedded groove 201b-1, and the arc-shaped connecting rod 201b-2b is horizontally inserted into the first arc plate 201c.

[0052] Furthermore, when the filter plate body 201b-2a rotates circumferentially along the embedded groove 201b-1, the filter plate body 201b-2a extends out of the embedded groove 201b-1 until the filter plate body 201b-2a completely extends out of the embedded groove 201b-1, but at this time, the arc-shaped connecting rod 201b-2b is still connected to the stabilizing slot 201b-1a to prevent it from falling.

[0053] A spring insertion hole 201c-1 is provided at one end of the first arc plate 201c close to the first fixed seat 201a, and a sliding hole 201c-2 is also provided on the outer wall of the first arc plate 201c. The spring insertion hole 201c-1 is connected to the sliding hole 201c-2, and a fixing member 201c-3 is slidably arranged in the spring insertion hole 201c-1; a first spring T1 is symmetrically fixed to the inner wall of the sliding hole 201c-2 at one end away from the first fixed seat 201a.

[0054] The fixing member 201c-3 includes a docking plate 201c-3a and a push plate 201c-3b and a plug-in block 201c-3c fixed at both ends thereof. The docking plate 201c-3a and the plug-in block 201c-3c are respectively slidably plugged into the sliding hole 201c-2 and connected to the sliding hole 201c-2, and the other end of the first spring T1 is fixed to the plug-in block 201c-3c.

[0055] In the initial state, the first spring T1 is in a naturally stretched state, pushing the plug-in block 201c-3c to extend out of the spring insertion hole 201c-1.

[0056] A docking slot 202b-1 is provided on the side wall of the second side arc wall 202b away from the second arc plate 202c, and a pushing slot 202b-1a is provided on the bottom inner wall of the docking slot 202b-1. The connecting block 201b-2c and the card strip 201b-2c1 can be slidably inserted into the docking slot 202b-1 and the pushing slot 202b-1a respectively.

[0057] An anti-drop hole 202c-1 is formed at one end of the second arc plate 202c close to the second fixing seat 202a, and the plug-in block 201c-3c is slidably plugged into the anti-drop hole 202c-1.

[0058] During use, the male head 201 and the female head 202 are plugged into each other. At this time, the connecting block 201b-2c and the card strip 201b-2c1 can be slidably plugged into the docking slot 202b-1 and the pushing slot 202b-1a respectively. When the male head 201 and the female head 202 are docked to the extreme position, the staff member uses his fingers to push the push plate 201c-3b to drive it to move toward the female head 202. At this time, the first spring T1 is squeezed and contracted.

[0059] Furthermore, after the first arc plate 201c and the second arc plate 202c can be fully inserted into the second card slot 202a-1 and the first card slot 201a-1 respectively, the push plate 201c-3b is released, the first spring T1 is reset, and the plug-in block 201c-3c is driven to be inserted into the anti-disconnection hole 202c-1, completing the circumferential locking of the male head 201 and the female head 202.

[0060] Furthermore, in this process, the slot 202b-1a is pushed and fixed with the snap-fit ​​strip 201b-2c1, so that when the second side arc wall 202b rotates, the filter plate 201b-2 can be driven to rotate circumferentially at the same time, bringing the filter plate 201b-2 out of the embedded groove 201b-1, blocking the sliding gap between the first side arc wall 201b and the second side arc wall 202b, and preventing dust and other impurities from entering the male head 201 and the female head 202 from here.

[0061] The remaining structures are the same as those of Example 1.

[0066] During the process of plugging the male connector 201 and the female connector 202 into each other, the second spring T2 and the third spring T3 in the naturally stretched state are forced to shrink, and the plug-in sealing ring 201e-1a is plugged into the sealing groove 202e-1a in a sealing manner, so that the ends of the first sealing sleeve 201e and the second sealing sleeve 202e are sealed and connected.

[0067] Furthermore, when the male head 201 and the female head 202 are completely fixed, the other ends of the first sealing sleeve 201e and the second sealing sleeve 202e are tightly fitted with the first fixing seat 201a and the second fixing seat 202a respectively. At this time, the first detection head 201d and the second detection head 202d are connected and sealed inside by the first sealing sleeve 201e and the second sealing sleeve 202e, isolated from the external environment.

[0068] The placement box 101 includes a base 101a and a support plate 101b symmetrically fixed on the top thereof. The two ends of the support plate 101b are fixedly connected with a first air-permeable baffle 101c, which connects the support plates 101b on both sides. A sealing cover 101d is also provided at one end of the support plate 101b.

[0069] At least one set of pressing holes 101b-1 are symmetrically and equidistantly provided on the two side support plates 101b, and sliding groove openings 101b-2 and fixed sliding openings 101b-3 are respectively provided on the two side support plates 101b between the pressing holes 101b-1.

[0070] A hinge rod 101b-4 is symmetrically fixed to the outer wall of one end of the two side support plates 101b, a second breathable baffle 101d-1 is symmetrically fixed to the bottom of the sealing cover 101d, and a hinge plate 101d-2 is symmetrically fixed to the two side walls of one end of the sealing cover 101d, and the end of the hinge plate 101d-2 is rotatably sleeved on the outside of the hinge rod 101b-4; the installation space A is located between adjacent slide groove openings 101b-2.

[0071] During use, when the placement box 101 is in a closed state as a whole, the sealing cover 101d horizontally covers the support plate 101b, and the first breathable baffle 101c and the second breathable baffle 101d-1 on both sides are also spliced ​​and combined with each other to form a breathable mesh panel on the side, which is connected to the external environment.

[0072] The cooling pipe 102 includes a bottom bracket 102a and a cooling air duct 102b. The bottom bracket 102a includes an arranged plug-in rod 102a-1 and a mounting plate 102a-2 fixed at one end thereof.

It should be noted that the distance between adjacent shunt tubes 102b-1a is smaller than the distance between adjacent joint units 200, so as to avoid collision between the joint unit 200 and the shunt tube 102b-1a when it is installed from above into the placement box 101.

[0076] Furthermore, when installing the connector unit 200, the snap-on cover 102b-3 will first contact and squeeze with the outer wall of the first side arc wall 201b and the second side arc wall 202b. When the male head 201 and the female head 202 are installed into the installation space A along the press-down hole 101b-1, the connector unit 200 will push the snap-on cover 102b-3 to move, and the fourth spring T4 will contract until the connector unit 200 can no longer move downward. At this time, the fourth spring T4 will reset, pushing the snap-on cover 102b-3 to be plugged into the cooling port B, so that the connector unit 200 can be clamped as a whole between the snap-on covers 102b-3.

[0077] Furthermore, after the snap-on cover 102b-3 completes the fixation of the joint unit 200, the airflow flowing out of the diverter pipe 102b-1a gradually fills the air dispersion groove 102b-3a, and then enters the joint unit 200 through the filter holes on the filter plate 201b-2, and blows toward the axial side walls of the first sealing sleeve 201e and the second sealing sleeve 202e, thereby accelerating the airflow velocity on the surface thereof, thereby cooling it.

[0078] The remaining structure is the same as that of Example 2.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention 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 invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
