Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to a testing equipment for wiring terminals of low-voltage distribution cabinets. Background Technique

[0002] Low-voltage distribution cabinets have the characteristics of strong breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong series and practicability, and novel structure. Wiring terminals are key electrical connection components for low-voltage distribution cabinets to maintain good performance. Wiring terminals facilitate more convenient docking between wires in low-voltage distribution cabinets. For example, for two wires, sometimes they need to be connected and sometimes they need to be disconnected. At this time, they can be connected through the terminals and can be disconnected at any time, without having to weld or wind the wires together, which is very convenient and fast. To ensure the firm connection between the wiring terminal and the wire and ensure the use safety, it is necessary to conduct a tensile test on the wiring terminal.

[0003] When the existing equipment conducts a tensile test on the wiring terminal, the wiring terminal is usually clamped at the bayonet, and then the wire is pulled to move for testing. However, during the detection, due to the large tensile strength, the long-term tensile test is likely to cause the fixing rod to bend downward. When the fixing rod bends, the wiring terminal is likely to slide out from the fixing rod. When the tensile strength is greater than the pressing force of the pressing component, at this time, when the wiring terminal slides out, it is easy to squeeze the limiting plate, resulting in the fracture of the limiting plate. For this reason, we propose a testing equipment for wiring terminals of low-voltage distribution cabinets. Content of the Utility Model

[0004] Aiming at the deficiency of the inconvenient use of the testing equipment for wiring terminals of low-voltage distribution cabinets in the prior art, the utility model provides a testing equipment for wiring terminals of low-voltage distribution cabinets, which has the advantages of convenient replacement of the fixing rod and convenient installation and disassembly of the wiring terminal.

[0005] To achieve the above object, the utility model provides the following technical scheme: A testing equipment for wiring terminals of low-voltage distribution cabinets, including a fixing plate, a fixing ring is fixedly connected to the back of the fixing plate, a fixing rod is slidably connected inside the fixing ring, a protrusion is arranged at the head of the fixing rod, a retaining ring is fixedly connected to the back of the protrusion, a limiting ring is fixedly connected to the outside of the fixing rod, a fixing nut is detachably connected to the tail of the fixing rod, a fixing shell is fixedly connected to the outside of the fixing plate, a rotating shaft is rotatably connected inside the fixing shell, and a limiting plate is fixedly connected to the outside of the rotating shaft.

[0006] Preferably, a limiting groove corresponding to the limiting plate is opened inside the fixing shell, the limiting plate is slidably connected inside the limiting groove, springs are fixedly connected to both ends of the rotating shaft, and the tail ends of the springs are fixedly connected to the fixing shell.

[0007] Preferably, a fixing block is fixedly connected to the outside of the fixing plate. A limiting groove corresponding to the limiting plate is formed inside the fixing block. The limiting groove is arranged in an arc structure, and the limiting plate is slidably connected to the inside of the limiting groove.

[0008] Preferably, a wiring terminal is slidably connected to the outside of the fixing rod. A hole is formed at the tail of the wiring terminal, and the cross-sectional area of the hole is larger than that of the protrusion provided at the head of the fixing rod. A wire is fixedly connected to the bottom of the wiring terminal.

[0009] Preferably, a bracket is fixedly connected to the bottom of the fixing plate. A cylinder is installed on the top of the bracket. A connecting plate is fixedly connected to the tail of the cylinder. A clamp is installed at the tail of the connecting plate, and the clamp can clamp the wire.

[0010] Preferably, the distance from the limiting plate to the fixing plate is greater than the distance from the retaining ring to the fixing plate. The retaining ring is fixedly connected to the fixing rod, and the retaining ring is arranged in an arc structure to facilitate the wiring terminal to break away from the fixing rod.

[0011] Preferably, the length of the fixing rod is greater than the sum of the lengths of the fixing plate and the fixing ring. A limiting groove body corresponding to the fixing rod is formed inside the fixing plate, and the fixing rod is slidably connected to the inside of the groove body, and the fixing rod can limit the position of the wiring terminal.

[0012] Beneficial effects:

[0013] 1. For this wiring terminal testing device of the low-voltage power distribution cabinet, the position of the wiring terminal is fixed by the fixing rod, and a limiting plate is arranged to abut against the outside of the wiring terminal to prevent the wiring terminal from breaking away from the fixing rod after being stressed. At the same time, the setting of the limiting ring restricts the position of the fixing rod relative to the fixing plate on the one hand, and on the other hand, when the fixing rod is stressed, it can receive the support of the fixing plate. By increasing the contact area with the fixing plate, the force received by the fixing rod is dispersed, thereby improving the stability of the fixing rod.

[0014] 2. For this wiring terminal testing device of the low-voltage power distribution cabinet, the spring is used to control the limiting plate to be in a state parallel to the fixing plate to maintain the restriction on the position of the wiring terminal. At the same time, the spring can deform under stress to provide an operating space when installing and disassembling the wiring terminal, so as to facilitate the installation and disassembly of the wiring terminal. The structure is simple and easy to use. Brief description of the drawings

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 3 , a low-voltage power distribution cabinet terminal testing device, including a fixed plate 1, a fixed ring 2 is fixedly connected to the back of the fixed plate 1, a fixed rod 3 is slidably connected inside the fixed ring 2, a protrusion is provided at the head of the fixed rod 3, a retaining ring 4 is fixedly connected to the back of the protrusion, a limiting ring 5 is fixedly connected to the outside of the fixed rod 3, a fixing nut 6 is detachably connected to the tail of the fixed rod 3, a fixed housing 7 is fixedly connected to the outside of the fixed plate 1, a rotating shaft 8 is rotatably connected inside the fixed housing 7, and a limiting plate 10 is fixedly connected to the outside of the rotating shaft 8.

[0022] Among them, a fixing block 11 is fixedly connected to the outside of the fixed plate 1, a limiting groove 12 corresponding to the limiting plate 10 is opened inside the fixing block 11, the limiting groove 12 is set as an arc structure, and the limiting plate 10 is slidably connected inside the limiting groove 12.

[0023] Among them, a terminal 13 is slidably connected to the outside of the fixed rod 3, a hole is opened at the tail of the terminal 13, the cross-sectional area of the hole is larger than the cross-sectional area of the protrusion provided at the head of the fixed rod 3, and a wire 14 is fixedly connected to the bottom of the terminal 13.

[0024] Among them, a bracket 18 is fixedly connected to the bottom of the fixed plate 1, a cylinder 15 is installed on the top of the bracket 18, a connecting plate 16 is fixedly connected to the tail of the cylinder 15, and a fixture 17 is installed on the tail of the connecting plate 16. The fixture 17 can clamp the wire 14.

[0025] Among them, the distance from the limiting plate 10 to the fixed plate 1 is greater than the distance from the retaining ring 4 to the fixed plate 1. The retaining ring 4 is fixedly connected to the fixed rod 3, and the retaining ring 4 is set as an arc structure to facilitate the terminal to break away from the fixed rod 3.

[0026] Among them, the length of the fixed rod 3 is greater than the sum of the lengths of the fixed plate 1 and the fixed ring 2. A limiting groove body corresponding to the fixed rod 3 is opened inside the fixed plate 1. The fixed rod 3 is slidably connected to the inside of the groove body, and the fixed rod 3 can limit the position of the terminal 13.

[0027] Working principle: When the low-voltage power distribution cabinet terminal testing device is used, the terminal 13 can be controlled to pass through the bottom of the limiting plate 10, and then the limiting plate 10 is extruded outwards to drive the spring 9 to deform, which is convenient for sleeving the terminal 13 outside the fixed rod 3. Then, under the action of gravity, after passing through the protrusion provided at the head of the fixed rod 3, the terminal 13 can move downwards to abut against the outside of the fixed rod 3, so that the limiting plate 10 abuts against the outside of the terminal 13, avoiding the terminal 13 from moving towards the direction close to the protrusion. At the same time, the fixed rod 3 fixes the position of the terminal 13 to provide support during testing. At the same time, the setting of the limiting ring 5 limits the position of the fixed rod 3 relative to the fixed plate 1 on the one hand, and on the other hand, when the fixed rod 3 is stressed, it can receive the support of the fixed plate 1. By increasing the contact area with the fixed plate 1, the force received by the fixed rod 3 is dispersed, thereby improving the stability of the fixed rod 3. After the test is completed, the terminal 13 is controlled to extrude the limiting plate 10 outwards to take out the terminal 13. The retaining ring 4 can support the terminal 13 to avoid the protrusion from restricting the terminal 13, reducing the difficulty of the terminal 13 detaching. When the fixed rod 3 is damaged, the fixing nut 6 can be disassembled to take out the fixed rod 3, and the operation is convenient.

The limiting plate 10 is slidably connected to the inside of the limiting groove body. Springs 9 are fixedly connected to both ends of the rotating shaft 8, and the tail ends of the springs 9 are fixedly connected to the fixed housing 7.

[0030] Working principle: When the low-voltage power distribution cabinet terminal testing device is used, the spring 9 can be used to control the limiting plate 10 to be in a state parallel to the fixed plate 1 to maintain the restriction on the position of the terminal 13. At the same time, the spring 9 can be stressed and deformed to provide an operating space when installing and disassembling the terminal 13, facilitating the installation and disassembly of the terminal 13. The structure is simple and easy to use.
