Description

Technical Field

[0001] This utility model relates to the field of relay technology, and specifically to an easy-to-assemble relay. Background Art

[0002] A relay is an electronic control device commonly used in automatic control circuits. It acts as an "automatic switch," playing a crucial role in circuits for automatic adjustment, safety protection, and circuit switching. This invention presents an improved relay structure. Chinese patent CN208352209U discloses a highly sensitive relay, comprising a base and a main body structure of the relay fixed to the base. A through-hole reel is connected to the upper left side of the base, with a coil wound around its outer edge. The through-hole reel is connected to the tail end of an iron core and fixed to its bottom. An "L"-shaped yoke is mounted on one side of the through-hole reel via a positioning structure. A hook is mounted on the yoke, movably connected to an "L"-shaped iron piece, which is mounted at the bottom of the iron core. A movable terminal and a fixed terminal are mounted on the right side of the base. The movable terminal is connected to the "L"-shaped iron piece via a push-pull contact mechanism. This invention provides a highly sensitive relay that achieves synchronized operation of all components, saves consumables, reduces costs, and facilitates easy assembly and disassembly, improving overall synchronization and enhancing the relay's sensitivity for better circuit protection.

[0003] The existing technology has the following shortcomings: In the existing technology, the connection between the push card and the movable terminal extends between the stationary terminal and the movable terminal, which can easily obstruct normal contact between the stationary and movable terminals; furthermore, during the assembly process of the push card and the movable terminal, the movable terminal is prone to deformation, resulting in a higher product quality risk; additionally, the push card's pushing position is located below the contact point between the stationary and movable terminals, requiring greater magnetic force to push the movable terminal. Therefore, an easily assembled relay is provided to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that

[0005] The technical solution adopted by this utility model to solve the technical problem is: an easy-to-assemble relay, which is composed of: a relay base, a terminal assembly and a power mechanism. The terminal assembly includes a stationary terminal, a movable terminal, a stationary contact point, a moving contact point, a slot and a pusher. The stationary terminal and the movable terminal are both snapped into the inside of one end of the relay base. The stationary contact point is located on one side of the upper end of the stationary terminal, and the moving contact point is located on one side of the upper end of the movable terminal. The slot is located on both sides of the movable terminal above the moving contact point, and the pusher is sleeved on the top of the movable terminal from top to bottom.

[0006] As a preferred embodiment of this utility model, the push card is provided with a card post on one side of the movable terminal, the card post matches the card slot, and a limit plate is provided on the opposite end of the push card and the card post.

[0007] As a preferred technical solution of this utility model, the relay base has a groove on the side facing the limiting plate, and the limiting plate is inserted into the groove from top to bottom.

[0008] As a preferred technical solution of this utility model, the relay base is provided with a hook on the side near the push card, and the hook is provided with buckles on both sides of the middle part, and the hook is fastened to one side of the yoke by the buckles.

[0009] As a preferred technical solution of this utility model, the power mechanism includes an iron sheet, an iron core, a coil body, and coil terminals. A notch is opened on one side of the middle part of the iron sheet. The two ends of the iron core are respectively connected between the yoke and the relay base. The coil body is sleeved on the outside of the iron core, and the coil terminals are connected to the coil body.

[0010] In a preferred embodiment of this utility model, the iron sheet is inserted between the yoke and the hook, the coil terminal is snapped into the inside of the relay base, and both the yoke and the iron sheet are L-shaped structures.

[0012] The present invention has the following advantages: the movable terminal can deform according to the assembly of the push card, automatically avoids, reduces the deformation of the movable terminal, and is easy to automate. The iron sheet is more convenient to be assembled with the hook through the notch.

[0013] The push position of the push card is located above the static contact point and the moving contact point. This not only increases the lever arm of the push card to push the movable terminal, but also effectively avoids the problem of the traditional push card protruding at the connection point of the movable terminal and extending to the contact point between the static terminal and the movable terminal. This prevents foreign objects at the contact point from affecting the connection, thus ensuring the reliability, consistency and quality of the product. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Please refer to Figures 1-4 This utility model discloses an easy-to-assemble relay, which consists of a relay base 1, a terminal assembly, and a power mechanism. The terminal assembly includes a stationary terminal 2, a movable terminal 3, a stationary contact point 4, a moving contact point 5, a slot 6, and a pusher 8. The stationary terminal 2 and the movable terminal 3 are both snapped into the interior of one end of the relay base 1. The stationary contact point 4 is located on one side of the upper end of the stationary terminal 2, and the moving contact point 5 is located on one side of the upper end of the movable terminal 3. The slot 6 is located on both sides of the movable terminal 3 above the moving contact point 5. The pusher 8 is sleeved on the top of the movable terminal 3 from top to bottom.

[0023] Combination Figure 2 and Figure 4 As shown, the push card 8 is provided with a locking post 10 on one side of the movable terminal 3. The locking post 10 matches the locking groove 6, thereby ensuring the stability of the connection structure between the movable terminal 3 and the push card 8. A limit plate 9 is provided on the opposite end of the push card 8 and the locking post 10. A groove 7 is provided on the side of the relay base 1 facing the limit plate 9. The limit plate 9 is inserted into the groove 7 from top to bottom. The groove 7 and the limit plate 9 can ensure the stability of the structure when the push card 8 moves. A hook 11 is provided on the side of the relay base 1 near the push card 8. Buckles 12 are symmetrically provided on both sides of the middle of the hook 11. The hook 11 is fastened to one side of the yoke 15 through the buckles 12. The hook 11 is used to limit the iron piece 13.

[0024] The power mechanism includes an iron sheet 13, an iron core 16, a coil body 17, and a coil terminal 18. The iron sheet 13 has a notch 14 on one side of its middle section, which facilitates assembly with the hook 11. The two ends of the iron core 16 are connected between the yoke 15 and the relay base 1, respectively. The coil body 17 is sleeved on the outside of the iron core 16, and the coil terminal 18 is connected to the coil body 17. The iron sheet 13 is inserted between the yoke 15 and the hook 11, and the coil terminal 18 is snapped into the inside of the relay base 1. Both the yoke 15 and the iron sheet 13 are L-shaped structures. The moving contact point 5 is directly opposite the stationary contact point 4. The push card 8 is located on one side of the limit plate 9 and contacts the upper end of the iron sheet 13. The upper end of the relay base 1 is provided with a shell 19. When the coil body 17 is energized, the bottom of the iron core 16 generates a magnetic force, which can attract the bottom of the iron sheet 13. The upper end of the iron sheet 13 then pushes the push card 8, thereby causing the push card 8 to push the movable terminal 3 to connect with the stationary terminal 2.

[0025] Specifically, compared to the relay in the prior art (CN208352209U), the push card 8 of this utility model is assembled on the movable terminal 3 by pressing it from above, and the limiting plate 9 on the push card 8 is inserted into the groove 7 to complete the assembly of the push card 8. This allows the movable terminal 3 to automatically avoid interference with the movable terminal 3 during use, even if it interferes with the movable terminal 3, the movable terminal 3 can deform according to the assembly of the push card 8, reducing the deformation of the movable terminal 3. Moreover, the pushing position of the push card 8 is located above the contacts (static contact point 4 and moving contact point 5), which not only increases the force arm of the push card 8 pushing the movable terminal 3, but also avoids the force arm effect of the push card 8 being located below the contacts in the prior art, as well as the foreign objects generated by the push card 8 at the contact foot position during the assembly process.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
