Abstract
Description
Technical Field
[0001] This utility model relates to the field of relay technology, and more specifically, to a meter relay with a compact structure and good heat dissipation performance. Background Technology
[0002] A relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. In daily life, a compact meter relay with good heat dissipation performance is needed.
[0003] Traditional relays are not compact enough, are large in size, and occupy a large area of the board. In addition, traditional relays generally use external copper terminals, which results in poor heat dissipation, reducing the overall portability and practicality of the relay, increasing the production cost of the relay, and reducing the overall lifespan of the relay.
[0004] Therefore, those skilled in the art have provided a compact meter relay with excellent heat dissipation to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a compact meter relay with good heat dissipation performance, including a base, and further comprising:
[0006] The outer casing is disposed outside the base;
[0007] A skeleton is fixedly installed inside the base, and yokes are symmetrically arranged on the outside of the skeleton. Coils are also arranged on the outside of the skeleton.
[0008] A magnetic steel structure is installed inside the base;
[0009] The first movable piece and the second movable piece are both disposed inside the base. The first movable piece is riveted to the outside with a first three-arch piece, and the second movable piece is riveted to the outside with a second three-arch piece. The first three-arch piece is riveted to the inside with a first movable contact, and the second three-arch piece is riveted to the inside with a second movable contact.
[0010] The first stationary plate and the second stationary plate are both disposed inside the base. The first stationary plate has a first stationary contact riveted inside, and the second stationary plate has a second stationary contact riveted inside.
[0011] Sampling components are respectively disposed outside the first moving plate and the second moving plate;
[0012] The pusher component is located inside the base.
[0013] As a further improvement to this technical solution, the sampling component includes manganese-copper sampling structures respectively disposed outside the first moving plate and the second moving plate.
[0014] As a further improvement to this technical solution, the pushing component includes a pusher plate disposed inside the base, and the pusher plate has movable slots respectively provided for the first three bow plates, the second three bow plates and the magnetic steel structure to move.
[0015] As a further improvement to this technical solution, the base is provided with symmetrical protrusions on the outside, and the shell is provided with a snap-fit groove for snapping the protrusions inside.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] In this compact meter relay with excellent heat dissipation, a sampling component and a pushing component are used. When the coil is energized, a magnetic field is generated. The yoke attracts one side of the magnet structure, causing it to close. The magnet structure then moves the pusher plate, causing the first and second moving plates to move towards the first and second stationary plates through the slots on the pusher plate until the first moving contact closes with the first stationary contact and the second moving contact closes with the second stationary contact. At this point, the circuit is connected. When the first moving contact closes with the first stationary contact and the second moving contact closes with the second stationary contact, the manganese-copper sampling structure begins monitoring the current and acquiring signals. Its function is to... The meter's metering and control functions provide high-precision current signals. When the current is abnormal, it sends an abnormal signal to the meter, thereby controlling the relay to disconnect and preventing circuit burnout and fires. This effectively extends the overall lifespan of the relay. Furthermore, this relay has a more compact structure and smaller size, effectively reducing the overall board area occupied by the relay. Unlike traditional meter relays, this relay incorporates the manganese copper sampling structure, which would normally be on the outside of the relay, into the relay itself, greatly saving the volume of the external copper terminals and thus reducing costs. In addition, the manganese copper sampling structure uses an open structure, thereby reducing relay heat generation and extending the relay's lifespan. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 - Figure 4 As shown, this embodiment provides a compact meter relay with good heat dissipation performance, including a base 1, and further including:
[0026] The outer casing 2 is disposed outside the base 1;
[0027] The frame 3 is fixedly installed inside the base 1. The frame 3 is symmetrically provided with yokes 5 on the outside and coils 4 on the outside.
[0028] The magnetic steel structure 6 is installed inside the base 1;
[0029] The first moving piece 8 and the second moving piece 11 are both located inside the base 1. The first moving piece 8 is riveted to the outside with a first three-bow piece 9, and the second moving piece 11 is riveted to the outside with a second three-bow piece 12. The first three-bow piece 9 is riveted to the inside with a first moving contact 10, and the second three-bow piece 12 is riveted to the inside with a second moving contact 13.
[0030] The first stationary plate 14 and the second stationary plate 16 are both disposed inside the base 1. The first stationary plate 14 is riveted with a first stationary contact 15, and the second stationary plate 16 is riveted with a second stationary contact 17.
[0031] The sampling components are respectively disposed outside the first moving piece 8 and the second moving piece 11;
[0032] The pusher component is located inside the base 1.
[0033] The working principle described above is as follows: When coil 4 is energized, it generates a magnetic field. The yoke 5 attracts one side of the magnet structure 6, causing it to close. The magnet structure 6 then moves the pusher plate 7, causing the first three-bow plates 9 and 12 on the first moving plate 8 and the second moving plate 11 to move towards the first stationary plate 14 and the second stationary plate 16 through the slots on the pusher plate 7, until the first moving contact 10 and the first stationary contact 15 are closed, and the second moving contact 13 and the second stationary contact 17 are closed. At this point, the circuit is connected. When the first moving contact 10 and the first stationary contact 15 are closed, and the second moving contact 13 and the second stationary contact 17 are closed, the manganese-copper sampling structure 18 begins monitoring the current and acquiring signals. Its function is to provide power to the circuit. The meter's metering and control functions provide high-precision current signals. When the current is abnormal, it sends an abnormal signal to the meter, thereby controlling the relay to disconnect and preventing circuit burnout and fire. This effectively extends the overall lifespan of the relay. Furthermore, this relay has a more compact structure and smaller size, effectively reducing the overall board area occupied by the relay. At the same time, unlike traditional meter relays, this relay incorporates the manganese copper sampling structure 18, which should be on the outside of the relay, into the relay interior, greatly saving the volume of the external copper terminals and thus reducing costs. Moreover, the manganese copper sampling structure 18 uses an open structure, thereby reducing relay heat generation and further improving the relay's lifespan.
[0034] In order to effectively monitor the current and acquire signals, the sampling component includes manganese copper sampling structures 18 respectively disposed outside the first moving contact 8 and the second moving contact 11. When the first moving contact 10 and the first stationary contact 15 are closed and the second moving contact 13 and the second stationary contact 17 are closed, the manganese copper sampling structure 18 begins to monitor the current and acquire signals. Its function is to provide high-precision current signals for the meter's metering and control functions. When the current is abnormal, it will give the meter an abnormal signal, thereby controlling the relay to disconnect, avoiding circuit burnout and fire, effectively improving the overall service life of the relay and the safety factor of the relay during use.
[0035] Considering that the relay requires closure between the first moving contact 10 and the first stationary contact 15, and between the second moving contact 13 and the second stationary contact 17, the push assembly includes a push plate 7 located inside the base 1. The push plate 7 has movable slots inside for the first three-segment plate 9, the second three-segment plate 12, and the magnet structure 6 to move. When the coil 4 is energized, a magnetic field is generated. At this time, the yoke 5 attracts one side of the magnet structure 6 to close. During the closing process, the magnet structure 6 drives the push plate 7 to move synchronously. The push plate 7 then drives the first three-segment plate 9 and the second three-segment plate 12 to move synchronously. This allows the first moving contact 10 and the second moving contact 13 to move, enabling the first moving contact 10 to effectively open and close with the first stationary contact 15, and the second moving contact 13 to effectively open and close with the second stationary contact 17, thus enabling the relay to operate normally.
[0036] To facilitate the assembly of the relay by the staff, the base 1 is symmetrically provided with protrusions 19 on the outside, and the shell 2 is provided with a snap-fit groove for snapping the protrusions 19 inside. The protrusions 19 make it easy for the staff to assemble the shell 2 and the base 1, which effectively improves the assembly efficiency and effect of the relay and reduces the workload of the staff.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
