Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage cabinet inspection tools, in particular to a device for detecting the insertion depth of the incoming line plug of a low-voltage cabinet drawer unit. Background Technique

[0002] Low-voltage switch cabinets are divided into fixed type and draw-out type. Among them, the application amount of draw-out low-voltage switch cabinets accounts for 80% of the total amount of low-voltage switch cabinets. The draw-out switch cabinet consists of a cabinet body and drawer units. The drawer units are respectively provided with a primary incoming line plug, a primary outgoing line plug and a secondary plug. The corresponding primary incoming line socket, primary outgoing line socket and secondary socket are arranged in the cabinet body. Among them, the primary incoming line socket includes a positioning block with a socket and three vertically arranged copper bars. The socket faces the insertion end of the drawer unit. A positioning groove for inserting one copper bar respectively is arranged at one end of the positioning block far away from the socket. Three-phase conductive contacts are arranged in the primary incoming line plug. When the primary incoming line plug is inserted into the primary incoming line socket, only when the three-phase conductive contacts are in full contact with the three copper bars at the same time can the normal operation of the subsequent switch cabinet be ensured. For example, in a patent with the patent publication number CN220206576U, a detection mold for the insertion depth of the incoming line plug of a low-voltage cabinet drawer unit is recorded. Through a contact plate that is slidably arranged relative to the upper end face of a handheld plate, a relief groove for inserting a copper bar is recessed at the front end of the contact plate. An elastic member for driving the contact plate to be in an extended state is arranged between the contact plate and the handheld plate. A first marking line and a second marking line are arranged on the handheld plate at parallel intervals from the end close to the contact plate to the end far away from the contact plate. After the front end of the contact plate touches the conductive contact in the incoming line plug, the handheld plate moves towards the copper bar until it abuts against the copper bar. Observe the position of the end of the contact plate far away from the relief groove on the handheld plate. If it is on the first marking line or the second marking line or between the two, the insertion depth of the incoming line plug is qualified; if it is in other positions, the insertion depth of the incoming line plug is unqualified. This detection mold is convenient and accurate for detection and can improve the detection efficiency. However, this device cannot be extended, and it is too troublesome to detect some deeper incoming line sockets. At the same time, this device cannot be stored and is too troublesome to carry.

[0003] Based on this, a device for detecting the insertion depth of the incoming line plug of a low-voltage cabinet drawer unit is provided now, which can eliminate the drawbacks of the existing device. Content of the Utility Model

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Embodiment 1

[0027] In one embodiment, as Figures 1 - 6 shown, a depth detection device for the incoming line plug of a low-voltage cabinet drawer unit includes a detector 1. A connecting block 5 is slidably connected inside the detector 1, enabling the connecting block 5 to slide inside the detector 1. A positioning block 8 is provided on one side of the detector 1. An adjusting mechanism 4 for extending the device as required is provided inside the detector 1, enabling the connecting block 5 to be extended. A detection mechanism 6 for detecting the incoming line plug is provided inside the connecting block 5, which is used to detect whether the insertion depth of the incoming line plug is qualified.

[0028] In one embodiment, as Figure 2 shown, the adjusting mechanism 4 includes a chute 401, a clamping groove 402, a slider 403, a spring groove 404, a first spring 405, and a clamping pin 406. A chute 401 is provided inside the detector 1. Multiple groups of clamping grooves 402 are provided on one side of the detector 1. The inner wall of the chute 401 is slidably connected with a slider 403. A spring groove 404 is provided inside the slider 403. One end of the first spring 405 is fixedly connected to the spring groove 404 and the other end is fixedly connected to the clamping pin 406. The clamping pin 406 is slidably arranged in the spring groove 404. The outer end of the clamping pin 406 cooperates with the clamping groove 402. The top of the chute 401 is fixedly connected with the connecting block 5, and the connecting block 5 slides in the chute 401 through the slider 403. At this time, the inner wall of the detector 1 will squeeze the clamping pin 406 and the first spring 405. When the position of the slider 403 is appropriate, the first spring 405 resets and pushes the clamping pin 406 into the clamping groove 402, fixing the slider 403 in the detector 1. When detecting the incoming line plug at a deeper or shallower position, press the clamping pin 406 to make the clamping pin 406 engage in different clamping grooves 402, enabling the length adjustment of the detection mechanism 6 on the connecting block 5, so that the device can detect the incoming line plug at a deeper or shallower position.

[0029] In one embodiment, as Figure 5 shown, the diameter dimension of the first spring 405 matches the diameter dimension of the spring groove 404. When the first spring 405 expands and contracts, the spring groove 404 will limit the first spring 405 to prevent the first spring 405 from shaking.

[0030] In one embodiment, as Figure 3As shown in the figure, the detection mechanism 6 includes a groove 601, a limiting groove 602, a second spring 603, a fixed block 604, a connecting rod 605, a limiting block 606, a first marking line 607 and a second marking line 608. A groove 601 is formed at the top of the connecting block 5, and limiting grooves 602 are formed around the top of the connecting block 5. One end of the second spring 603 is fixedly connected to the groove 601 and the other end is fixedly connected to the fixed block 604. The inner wall of the groove 601 is slidably connected to the fixed block 604, so that the fixed block 604 can be inserted into the groove 601. The top of the fixed block 604 is fixedly connected to the connecting rod 605. Limiting blocks 606 are fixedly connected to the four peripheries of the bottom of the fixed block 604. The inner wall of the limiting groove 602 is slidably connected to the limiting block 606. The limiting block 606 can slide in the limiting groove 602, and at the same time prevent the fixed block 604 from falling out of the groove 601. First marking lines 607 and second marking lines 608 are provided on the peripheral surfaces of the connecting block 5 for displaying the detection results.

[0031] In one embodiment, as Figure 3 shown, the inner wall size of the groove 601 matches the outer wall size of the fixed block 604. When the fixed block 604 slides inside the groove 601, the groove 601 can limit the sliding of the fixed block 604 to prevent the fixed block 604 from shaking inside the groove 601.

[0032] Embodiment 2

[0033] In one embodiment, as Figure 1 shown, an insulating sleeve 2 is sleeved on the bottom of the detector 1 to protect the detection personnel and prevent the detector 1 from conducting electricity.

[0034] In one embodiment, as Figure 4 shown, a clamping block 3 is provided at the top of the detector 1, and a top cover 7 is sleeved on the top of the detector 1, so that the top cover 7 can cover the detector 1, enabling the device to be stored and carried conveniently. The clamping block 3 can prevent the top cover 7 from falling off easily.

[0035] In one embodiment, as Figure 5 shown, a plurality of positioning grooves 9 are formed on one side of the positioning block 8, and conductive contacts 10 are provided on the inner wall of the positioning grooves 9. A copper bar 11 is provided in the middle of the conductive contacts 10, and the copper bar 11 can be inserted into the positioning grooves 9.

[0036] Working principle: The above embodiment discloses a device for detecting the insertion depth of the incoming line plug of a low-voltage cabinet drawer unit. When in use, the top cover 7 is pulled out, and the connecting block 5 slides in the chute 401 through the slider 403. At this time, the inner wall of the detector 1 will squeeze the pin 406 and the first spring 405. When the position of the slider 403 is appropriate, the first spring 405 resets and pushes the pin 406 into the card slot 402, fixing the slider 403 in the detector 1. When it is necessary to detect the incoming line plug at a deeper or shallower position, press the pin 406 to make the pin 406 snap into different card slots 402, so that the detection mechanism 6 on the connecting block 5 can adjust the length, enabling the device to detect the incoming line plug at a deeper or shallower position. The copper bar 11 is inserted into the positioning groove 9 until the end of the connecting rod 605 touches the conductive contact 10. Then, continue to move forward until the end of the connecting block 5 touches the copper bar 11, causing the limiting block 606 to move backward in the groove 601 through the fixing block 604. The operator observes the position where the limiting block 606 stays on the first scale line 607 and the second scale line 608 to determine whether the insertion depth of the incoming line plug is appropriate. If it is on the first scale line 607 or the second scale line 608 or between the two, the insertion depth of the incoming line plug is qualified and the incoming line plug can be used normally. If it is in other positions (not touching the first scale line 607 or exceeding the second scale line 608), the insertion depth of the incoming line plug is unqualified and the incoming line plug needs to be replaced or repaired. When the use is completed, press the pin 406 to make the connecting block 5 slide into the chute 401 through the slider 403, and then cover the top cover 7 on the detector 1 to make the device portable for storage.

[0037] As described above, the above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
