Description

Technical Field

[0001] This invention relates to the field of fixture assembly technology, specifically to a fixture assembly for indirect lightning pin testing. Background Technology

[0002] In indirect lightning pin tests simulating interference from indirect lightning to electronic devices via interfaces, the fixture assembly is a key supporting component for ensuring test specifications and data reliability. On one hand, it must precisely fix the device under test, maintaining the preset accuracy between the device interface terminals and the test pins to prevent pin contact deviation due to device displacement. On the other hand, it must stably mount the pin-type interference injection device to ensure the injection pins meet standard requirements.

[0003] Currently, common clamping assemblies are prone to loosening during cable clamping, leading to poor contact. These assemblies are typically a single unit, making them inconvenient to carry and limiting their placement to specific locations, hindering testing in other areas. Furthermore, when performing multi-phase power tests, these assemblies require extending multiple power cables beyond the original number, increasing the risks associated with multi-phase power testing and raising the dangers for personnel.

[0047] The clamp assembly used for indirect lightning pin testing operates as follows:

[0048] like Figures 1 to 6 As shown, firstly:

[0049] Step 1: Align the first limiting block 104 with the first sliding groove 106, align the second limiting block 105 with the second sliding groove 107, then push the first mounting plate 102 and the second mounting plate 103. Next, place the mounting block 108 at both ends of the base plate 101, aligning the mounting hole with the threaded slot. Then, pass the fixing bolt through the mounting hole into the threaded slot to complete the installation process of the mounting block 108. The mounting block 108 limits the first mounting plate 102 and the second mounting plate 103. Next, pass the copper strip 206 through the bolt post 205, then pass the washer 207 through the bolt post 205 and place it inside the copper strip 206. Next, pass the hook block 208 through the bolt post 205 and place it on one side of the washer 207. Then, tighten the nut to ensure the effectiveness of the current output. The installation process is now complete. The hook block 208 can be connected to the oscilloscope probe, enabling faster and more accurate positioning of the signal to be acquired.

[0050] Step Two: Next, pull the first handle 303, causing the first spring 304 to elastically deform. This, through the sliding rod 302, moves the fixed collar 305 horizontally to the right. This, in turn, causes the first connecting rod 307 to change angle via the first connecting shaft 306. Consequently, the first connecting frame 308 moves vertically upward under the limiting action of the first limiting rod 309 and the first limiting groove. This, in turn, causes the first limiting rod 309 to move the first clamping block 3010 vertically. Then, multiple cables can be inserted into the first main female connector 201 and the first auxiliary female connector. On the inner side of 203, the first handle 303 is released, causing the first spring 304 to undergo elastic deformation, thereby causing the fixed collar 305 to move horizontally to the left. This causes the first connecting rod 307 to change angle through the first connecting shaft 306, thereby causing the first connecting frame 308 to move vertically downward under the limiting action of the first limiting rod 309 and the first limiting groove. This causes the first limiting rod 309 to drive the first clamping block 3010 to move vertically downward, thereby clamping the cable and increasing the friction with the cable through the toothed block design.

[0051] Step 3: Next, pull the third handle 4011, causing the second spring 4012 to elastically deform. At this time, the insert block 4013 will move vertically upward through the limiting rod 4010, thereby causing the insert block 4013 to disengage from the groove. Then, rotate the second handle 403 to drive the rotating rod 401 to rotate, thereby driving the second connecting shafts 405 on both sides to rotate through the turntable 404. This causes the second connecting rod 406 to change its angle, thereby causing the second connecting frame 407 to move horizontally under the limiting action of the second limiting rod 408 and the second limiting groove. This causes the second limiting rod 408 to drive the second clamping block 409 to move horizontally. Then, insert the cable into the inner side of the second main female connector 202 and the second auxiliary female connector 204, and then rotate the second handle. 403 drives the rotating rod 401 to rotate, which in turn drives the second connecting shafts 405 on both sides to rotate via the turntable 404. This causes the second connecting rod 406 to change its angle, which in turn causes the second connecting frame 407 to move horizontally under the limiting action of the second limiting rod 408 and the second limiting groove. This causes the second limiting rod 408 to drive the second clamping block 409 to move horizontally, so that the second clamping block 409 can clamp the cable. The toothed block design increases the friction with the cable. Then, the third handle 4011 is released, causing the second spring 4012 to deform elastically, so that the insert block 4013 enters the groove outside the second handle 403, thereby limiting the second handle 403. At this point, the test process can begin.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
