Description

Technical Field

[0043] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain the present invention rather than to limit it.

[0044] like Figure 1 As shown, an adjustable detection device of the present invention includes two parts: a clamping device 1 and a measuring component 2. The clamping device 1 is arranged at both ends of the measuring component 2; the clamping device 1 is connected and fixed with the buckle mouth 3-14 of the measuring component 2 by pressing the buckle head 1-12.

[0045] like Figures 2 to 4As shown, the clamping device 1 includes a fixed seat 1-11, a tension spring 1-2, a sliding seat 1-31, and a hook 1-41. The front of the fixed seat 1-11 has two snap heads 1-12, which are used to cooperate with the snap opening 3-14 of the measuring component 2 to connect and fix the clamping device 1 to the measuring component 2. The side of the fixed seat 1-11 has two convex grooves 1-13, which cooperate with the convex groove 1-32 of the sliding seat 1-31, and the sliding seat 1-31 can slide up and down in the groove. The tension spring 1-2 connects the fixed seat 1-11 and the sliding seat 1-31 to tighten the two. The front of the sliding seat 1-31 has a convex groove 1-32 that cooperates with the fixed seat for sliding. The bottom of the sliding seat 1-31 is provided with a through hole, and the hook 1-41 passes through the through hole. A lock 1-33 is provided at the top of the through hole. The tip of the lock 1-33 has triangular teeth that cooperate with the straight teeth 1-44 to increase the resistance of the hook 1-41 to the lateral sliding. The hook 1-41 has serrations 1-43 at the front end to increase friction with the terminal block, and a limit protrusion 1-42 at the rear end to prevent the hook from being pulled out completely. The middle straight teeth 1-44 cooperate with the lock 1-33 of the sliding seat 1-31 to control the length of the hook 1-41.

[0046] The measuring assembly 2 is composed of a guide piece 2-11 and a measuring piece 2-21. Figure 3 There are two tapped holes 2-12 on the head of the guide piece 2-11. After the guide piece 2-11 passes through the square hole 3-12 of the measuring piece, the first piece of the measuring piece and the tail piece of the measuring piece are fixed to the two guide pieces with screws.

[0047] like Figures 4 to 9As shown, the measuring piece 2-21 includes an intermediate shell 3-11, a spring piece 3-2, a tightening screw 3-3, a connecting conductor 3-4, a pin 3-5, a spring contact 3-61 and a spring piece 3-71. Two snap openings 3-14 are provided on both sides of the intermediate shell 3-11 to cooperate with the snap head of the clamping device for fixation. When the number of terminal rows that need to extract potential is less than the number of measuring pieces, the clamping device can be adjusted to a suitable position. The intermediate shell 3-11 also has two screw holes 3-12 for fixing the head and tail measuring pieces to the guide piece. The front side has four square holes 3-13 for the guide piece to slide. There are also two spring slots 3-17 for installing the spring piece 3-71. A conductor slot 3-16 is provided in the middle for placing the connecting conductor 3-4. The top of the intermediate housing 3-11 is provided with a boss with a threaded hole at the top. A connecting hole 3-15 is provided on the side of the boss. The connecting hole 3-15 connects to the conductor slot 3-16 and the threaded hole. The conductor 4-3 passes through the connecting hole 3-15 and connects to the connecting conductor 3-4. The clamping screw 3-3 passes through the threaded hole to secure the conductor 4-3. The spring leaf 3-2 limits the rotation angle of the spring contact to 0-90°. The clamping screw 3-3 secures the conductor, transmitting the measured potential. The connecting conductor 3-4 is used to transmit the potential. The pin 3-5 allows the spring contact 3-61 to rotate around it. If there are terminals in the terminal block that do not need to extract potential, the corresponding spring contact can be folded. The spring contact 3-61 consists of a contact base 3-62, an upper sleeve 3-63, a contact spring 3-64, and a lower sleeve 3-65, and is used to extract potential from the terminal block. The four legs 3-72 of the two reeds 3-71 are interference fit with the reed slots 3-17 of the adjacent intermediate housings, and the spacing between the measuring pieces can be adjusted by stretching the head and tail measuring pieces.

[0048] The potential signal extraction device uses Figure 10 and 11 As shown, first adjust the length of the hook 1-41 of the device, press down the sliding seat 1-31 of the device, then hook the hook onto the guide rail 4-2, stretch the measuring assembly horizontally, align the spring contact 3-61 and place it into the screw hole 4-12 of the terminal 4-11 to be measured. If there are terminals in the terminal block that do not need to extract signals, the corresponding spring contact of the device can be folded. The terminal potential signal will be transmitted through the spring contact 3-61 and the connecting conductor to the clamping screw. At this time, the terminal block potential can be provided to the test device in batches through the wire 4-3.
