Description

Technical Field

[0001] The utility model relates to the technical field of high - voltage relays, and particularly relates to a high - voltage relay assembly device. Background Technique

[0002] A relay is an electrical control device. When the change of the input quantity reaches the specified requirement, it is an electrical appliance that makes the controlled quantity undergo a predetermined step - change in the electrical output circuit. It has an interactive relationship between the control system and the controlled system and is usually applied to automated control circuits. Among them, high - voltage DC relays are widely used in industries such as automobiles, solar energy, wind energy, charging piles, energy storage systems, and industrial automation in the new - energy industry to achieve functions such as power protection, automated control, measurement, and communication. There is a core component in high - voltage DC relays, that is, a ceramic component. The ceramic component is an arc - extinguishing cavity for breaking the current and determines the key electrical performance parameters of the relay product. If the assembly is not standardized during the assembly of high - voltage relays, it will seriously affect the performance of the ceramic component. Therefore, after the high - voltage relay is assembled, it is necessary to remove the high - voltage relay and plug it into the corresponding test socket, and then test whether it is qualified through the test socket. If it is unqualified, it needs to be re - clamped and fixed on the assembly table, disassembled and reassembled. Such a process of assembling and testing relays will reduce the efficiency of assembling relays and affect the production and assembly speed of relays. For this reason, we have proposed a high - voltage relay assembly device. Content of the Utility Model

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 6, A high-voltage relay assembly device, including an installation and detection base 1, on which a liquid crystal display screen 2 for indicating whether the high-voltage relay is qualified is provided, so that it can be visually distinguished whether the assembly of the high-voltage relay is qualified. At the bottom end inside the installation and detection base 1, a slot is opened that can be plugged and electrically connected to the high-voltage relay. By plugging the high-voltage relay into the slot, the high-voltage relay is then turned on to detect the high-voltage relay. A detection device is assembled inside the installation and detection base 1, which is prior art and will not be elaborated in detail here. An operating ring plate 3 that can rotate on the installation and detection base 1 is provided on the installation and detection base 1, so that the operating ring plate 3 can rotate stably. A circular placement rack 4 is installed inside the installation and detection base 1. A plurality of fixing columns 7 that penetrate the placement rack 4 are movably connected to the placement rack 4. The bottom end of the fixing column 7 is fixed to the installation and detection base 1. Through the limitation of the fixing column 7, the vertical movement trajectory of the placement rack 4 can be determined, so that the placement rack 4 can be stably plugged into the slot. And a placement groove 5 corresponding to the base of the high-voltage relay to be installed is opened in the middle of the placement rack 4. The base of the high-voltage relay to be installed can be placed in the placement groove 5, so that the assembly of the high-voltage relay is more stable. And the placement groove 5 is communicated with the inside of the installation and detection base 1 to ensure that the high-voltage relay can be smoothly plugged into the slot. A plurality of clamping heads 6 are movably connected to the inner wall of the placement groove 5. The clamping heads 6 can move along a fixed trajectory on the placement rack 4 to clamp the base of the high-voltage relay to be installed. One end of the clamping head 6 abuts against a transmission component 9. Under the push of the transmission component 9, the clamping head 6 can move to clamp the base of the high-voltage relay to be installed. And when the transmission component 9 pushes the clamping head 6, one end of the transmission component 9 extends into the placement rack 4, and then the horizontal position of the placement rack 4 is limited, so that the high-voltage relay can be stably installed. The rotation of the operating ring plate 3 can drive the transmission component 9 to move. Under the action of the rotation of the operating ring plate 3, the transmission component 9 can be pushed to move and push the clamping head 6, so that the position of the placement rack 4 and the limitation of the base of the high-voltage relay to be installed can be completed in one step, making the operation more convenient.

[0022] Please refer to Figures 1 to 2 , A first spring 10 is sleeved on the fixing column 7. The bottom end of the first spring 10 is fixed to the installation and detection base 1, and the top end of the first spring 10 is fixed to the bottom of the placement rack 4. Under the action of the elastic force of the first spring 10, the placement rack 4 can automatically return to its original position. When the placement rack 4 is in its original position, the transmission component 9 can just move into the placement rack 4, making the operation more convenient.

[0023] Please refer to Figures 1 to 6, the transmission component 9 is movably connected to the installation and detection base 1, so that the transmission component 9 can move along a fixed track, and the transmission component 9 is in contact with the inner side of the operation ring plate 3, and the contacting end is arc-shaped, thus making the pushing of the operation ring plate 3 smoother. The operation ring plate 3 includes an extension part 11 inside the installation and detection base 1, and the extension part 11 is arc-shaped. When the operation ring plate 3 rotates, its extension part 11 can contact the transmission component 9 and push the transmission component 9 to move.

[0024] Please refer to Figures 1 to 6 , a fourth spring 17 is fixedly connected to the inner side of the transmission component 9, and one end of the fourth spring 17 is fixed to the installation and detection base 1. Under the action of the elastic force of the fourth spring 17, the transmission component 9 can smoothly return to its original position, and the transmission component 9 can be separated from the state of extending into the placement rack 4, so that the placement rack 4 can move vertically. And a third spring 16 is fixedly connected to the clamping head 6, and one end of the third spring 16 is fixed to the placement rack 4. Under the action of the elastic force of the third spring 16, the clamping head 6 can return to its original position, facilitating the next clamping.

[0025] Please refer to Figures 1 to 5 , a plurality of ratchet grooves 12 are formed on the outer side of the top end of the installation and detection base 1. A connecting rod 15 is connected to the inside of the operation ring plate 3 through a pin, forming a hinge structure with the pin as the rotation axis, so that the connecting rod 15 can rotate stably. A ratchet tooth 13 that can rotate inside the operation ring plate 3 is fixedly connected to the connecting rod 15. Driven by the connecting rod 15, the ratchet tooth 13 can rotate, so that the ratchet tooth 13 can be separated from the clamped state with the ratchet groove 12. The ratchet tooth 13 can be clamped with the ratchet groove 12, and when the ratchet tooth 13 is clamped with the ratchet groove 12, the ratchet groove 12 can be limited to rotate in one direction, thereby locking the position of the extension part 11 after rotation, preventing the operation ring plate 3 from rotating in the reverse direction and causing the clamping of the clamping head 6 to become loose, so that the clamping is more stable.

[0026] Please refer to Figures 1 to 5 , one end of the ratchet tooth 13 away from the ratchet groove 12 is fixedly connected to a second spring 14, and one end of the second spring 14 is fixed to the operation ring plate 3. At the same time, the top end of the connecting rod 15 extends out of the operation ring plate 3 and is fixedly connected to a rotating wheel 8. Under the action of the elastic force of the second spring 14, when the operation ring plate 3 rotates and the ratchet tooth 13 is pushed into the operation ring plate 3, the ratchet tooth 13 can automatically extend out of the operation ring plate 3 and be clamped with the ratchet groove 12, thus achieving the effect of one-way rotation.

[0027] In summary, when using this high-voltage relay assembly device, place the base of the high-voltage relay to be installed in the placement groove 5. Then rotate the operation ring plate 3. The extension part 11 inside the operation ring plate 3 rotates and contacts the transmission component 9. As the operation ring plate 3 rotates continuously, it gradually pushes the transmission component 9 to move. The transmission component 9 extends into the placement rack 4 to limit the horizontal position of the placement rack 4. And through the push of the transmission component 9, the clamping head 6 can move in the placement groove 5 to clamp the base of the high-voltage relay to be installed. When the installation and detection base 1 rotates, its ratchet teeth 13 can rotate relatively, enabling the operation ring plate 3 to rotate smoothly. After the clamping head 6 limits the base of the high-voltage relay to be installed, the ratchet teeth 13 are engaged with the ratchet groove 12 under the elastic force of the second spring 14, preventing the operation ring plate 3 from rotating in the reverse direction and causing the clamping of the clamping head 6 to become loose. After the high-voltage relay is assembled, twist the rotating wheel 8 to drive the ratchet teeth 13 to rotate and disengage from the ratchet groove 12 through the connecting rod 15. Thus, the operation ring plate 3 can rotate in the reverse direction. Under the elastic force of the fourth spring 17, the transmission component 9 extends out of the placement rack 4, enabling the placement rack 4 to move vertically. Then press down the placement rack 4 so that the high-voltage relay in the placement groove 5 can be inserted and connected to the socket to detect the high-voltage relay.
