Description

Technical Field

[0001] This invention belongs to the field of relays, and more specifically, relates to a vertical electromagnetic relay. Background Technology

[0002] An electromagnetic relay is an electrical control device used as a contactor to implement electrical signals in a circuit. It works by generating an electromagnetic field through an energized coil, magnetizing the iron core, and attracting mechanical contacts to close or open the circuit. It plays a role in automatic adjustment, safety protection, and circuit switching. Currently, traditional electromagnetic relays have conductive plugs at the bottom. When wiring, the plugs are directly inserted into the conductive sockets on the side of the terminal block for conductive connection. This traditional connection structure is too simple and lacks secure fixing. It relies solely on two sets of elastic conductive copper plates in the conductive sockets to clamp the plugs. If the electromagnetic relay is subjected to external impacts or vibrations, it is very easy for it to detach from the terminal block, resulting in poor contact and failure of the electrical control signal in the control circuit. Furthermore, the exposed contact points of the terminal block at the bottom of the electromagnetic relay allow dust to easily accumulate and is difficult to clean. Over time, this can easily lead to static electricity and fire at the contact points, damaging the electromagnetic relay. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a vertical electromagnetic relay, which solves the issues of insecure installation and fixing measures in traditional electromagnetic relays, as well as the problem of exposed relay terminal block structure being prone to dust accumulation.

[0004] This invention provides a vertical electromagnetic relay, including an electromagnetic relay; the bottom of the electromagnetic relay is bolted to a base, and a transparent cover is installed on the upper side of the base. Silicone thermal conductive pads are adhered to both the left and right sides of the transparent cover, and a heat sink is adhered to the outer side of each silicone thermal conductive pad; the invention also includes a relay mounting and wiring device; the relay mounting and wiring device includes a terminal block, a dust cover, a sleeve, a limiting fixing plate, a knob, a rotary knob, a bidirectional threaded rod, a guide limiting rod, a spring, a guide rod, a clamping bolt, a clamping plate, and a conductive contact plate; the terminal block has protruding plates on both its front and rear sides. A clamping bolt is screwed onto the upper side of the terminal block's convex plate. A clamping plate is nested on the outer side of the clamping bolt. An L-shaped channel is provided on the inner side of the terminal block, and a conductive contact plate is bonded to the L-shaped channel. The terminal block is welded to the guide rod. A knob is welded to the right end of the bidirectional threaded rod, and a limit fixing plate is engaged with the outer side of the bidirectional threaded rod. A small through hole is provided on the front side of the dust cover near the right end. A guide limit rod is rotatably connected to the small through hole of the dust cover, and a knob is installed at the front end of the guide limit rod. The dust cover is bonded to the socket. The spring is welded to the dust cover and to the terminal block.

[0005] In at least some embodiments, the number of dust covers is two sets, and the dust covers are symmetrically distributed on the front and rear sides of the terminal block. Each set of dust covers is a groove structure made of transparent plastic material. The dust cover groove has a protruding post inside, and a circular hole groove is provided at the center of the rear end of the protruding post. The guide rod is embedded in the circular hole groove of the protruding post of the dust cover. Two sets of large through holes are provided on the front side of the outer side of the dust cover groove, and a plug sleeve is glued inside the large through holes.

[0006] In at least some embodiments, the sleeve is a cylindrical structure that runs through the front and back, the sleeve is made entirely of soft silicone material, and the front end of the cylindrical structure of the sleeve is a constricted structure.

[0007] In at least some embodiments, the upper side of the terminal block is provided with two sets of elongated grooves symmetrically distributed from left to right. The bottom of the limiting and fixing plate is embedded in the elongated groove of the terminal block. Each set of elongated grooves of the terminal block is provided with a through hole structure that runs from left to right on the left and right sides. The outer side of the bidirectional threaded rod is rotatably connected to the through hole of the terminal block. The front and rear sides of the terminal block are provided with two sets of circular deep holes symmetrically distributed from left to right. The guide limiting rod and the protruding column structure of the dust cover are respectively inserted into the two sets of deep holes of the terminal block. The inner wall of the right deep hole of the terminal block is provided with a groove.

[0008] In at least some embodiments, the outer side of the guide limit rod is provided with a protrusion, and the protrusion structure on the outer side of the guide limit rod is embedded in the groove of the inner wall of the deep hole on the right side of the terminal block.

[0009] In at least some embodiments, the number of limiting and fixing plates is two sets, which are symmetrically distributed in two sets of grooves in the terminal block seat. Each set of limiting and fixing plates has two sets of inverted L-shaped protrusions on its upper side. Each set of limiting and fixing plates has a threaded through hole that runs through the left and right sides at its center. The forward threaded end of the outer side of the bidirectional threaded rod is engaged with the threaded through hole in the right limiting and fixing plate, and the reverse threaded end of the outer side of the bidirectional threaded rod is engaged with the threaded through hole in the left limiting and fixing plate.

[0010] In at least some embodiments, the number of heat sinks is two sets, and each set of heat sinks is tightly attached to the left and right sides of the transparent cover by silicone thermal conductive pads, and the surface of the heat sinks is densely covered with a large number of horizontally arranged fin structures.

[0011] In at least some embodiments, the upper side of the base is provided with a through groove that runs vertically through the front end and the end, and the two sets of inverted L-shaped protrusions of the limiting and fixing plate are respectively inserted into the through groove of the base.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, a threaded engagement transmission structure is formed by a bidirectional threaded rod in the threaded through holes of two sets of limiting and fixing plates. This allows two sets of inverted L-shaped protrusions on the upper side of each set of limiting and fixing plates to slide left or right along the through groove of the base. The L-shaped protrusions of the two sets of limiting and fixing plates are engaged at the left and right edges of the through groove of the base, thus realizing the locking and limiting operation of the limiting and fixing plates on the base. This eliminates the simple power-on plug-in method between the electromagnetic relay and the terminal block, making the installation of the electromagnetic relay on the terminal block more stable and secure. It prevents the electromagnetic relay from falling off the terminal block due to vibration and ensures the stable operation of the electrical control signal transmission of the control circuit.

[0013] 2. In this invention, two sets of dust cover groove structures are used to cover and shield the wiring positions at the front and rear ends of the terminal block, and the soft silicone sleeves are used to seal the wires through the large through holes of the dust cover through the narrowing structure. This eliminates the exposed structure of the traditional electromagnetic relay terminal block and effectively prevents the accumulation and contamination of external dust at the wiring positions.

[0014] 3. In this invention, the silicone thermally conductive pads that are tightly attached to the left and right sides of the transparent cover and the horizontal fin structure densely distributed on the surface of the heat sink utilize the air convection characteristics between the multiple sets of fins of the heat sink to accelerate the natural conduction and heat dissipation of heat from the transparent cover, thereby reducing the temperature of the environment inside the transparent cover where the electromagnetic relay is located.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] like Figures 1-9As shown, the present invention provides a vertical electromagnetic relay, including an electromagnetic relay 6; the bottom of the electromagnetic relay 6 is bolted to a base 4, a transparent cover 1 is installed on the upper side of the base 4, and silicone thermal conductive pads 3 are adhered to the left and right sides of the transparent cover 1, and a heat sink 2 is adhered to the outer side of the silicone thermal conductive pads 3; it also includes a relay mounting wiring device 5; the relay mounting wiring device 5 includes a terminal block 501, a dust cover 502, a socket 503, a limiting fixing plate 504, a knob 505, a rotary knob 506, a bidirectional threaded rod 507, a guide limiting rod 508, a spring 509, a guide rod 510, a clamping bolt 511, a clamping piece 512, and a conductive contact piece 513; the terminal block 501 has protruding plates on both the front and rear sides, and the terminal block 501 protrudes... A clamping bolt 511 is screwed onto the upper side of the plate, and a clamping piece 512 is nested on the outer side of the clamping bolt 511. An L-shaped channel is provided on the inner side of the terminal block seat 501, and a conductive contact piece 513 is bonded to the L-shaped channel of the terminal block seat 501. The terminal block seat 501 is welded to the guide rod 510. A knob 505 is welded to the right end of the bidirectional threaded rod 507, and a limit fixing plate 504 is engaged with the outer side of the bidirectional threaded rod 507. A small through hole is provided on the front side of the dust cover 502 near the right end. A guide limit rod 508 is rotatably connected to the small through hole of the dust cover 502, and a knob 506 is installed at the front end of the guide limit rod 508. The dust cover 502 is bonded to the sleeve 503. A spring 509 is welded to the dust cover 502 and to the terminal block seat 501.

[0027] In this embodiment, there are two sets of dust covers 502, which are symmetrically distributed on the front and rear sides of the terminal block 501. Each set of dust covers 502 is a transparent plastic groove structure. The groove of the dust cover 502 has a protruding post, and a circular slot is provided at the center of the rear end of the protruding post. The guide rod 510 is embedded in the circular slot of the protruding post of the dust cover 502, so that the guide rod 510 welded to the terminal block 501 guides and supports the dust cover 502. There are two sets of large through holes on the front side of the outer side of the groove of the dust cover 502. The insert sleeve 503 is glued inside the large through hole. The external wire is inserted into the insert sleeve 503 glued inside the large through hole of the dust cover 502, so as to complete the wire connection between the wiring position of the terminal block 501 inside the groove of the dust cover 502 and the external wire.

[0028] In this embodiment, the socket 503 is a cylindrical structure that runs through the front and back. The socket 503 is made of soft silicone material. The front end of the cylindrical structure of the socket 503 is a constricted structure. The external wire is inserted into the socket 503 from the constricted structure of the silicone material, so that the constricted structure of the socket 503 fits tightly against the wire sheath of the external wire. This ensures that the large through hole of the dust cover 502 is always sealed, preventing dust from entering the interior of the dust cover 502 through the gap between the large through hole and the external wire.

[0029] In this embodiment, the upper side of the terminal block 501 is provided with two sets of elongated grooves symmetrically distributed from left to right. The bottom of the limiting and fixing plate 504 is embedded in the elongated groove of the terminal block 501, so that the limiting and fixing plate 504 can move left and right along the elongated through groove of the terminal block 501. The left and right sides of the inner left and right sides of each set of elongated grooves of the terminal block 501 are provided with through holes that pass through from left to right. The outer side of the bidirectional threaded rod 507 is rotatably connected to the through hole of the terminal block 501 without threads. The front and rear sides of the terminal block 501 are provided with two sets of circular deep holes symmetrically distributed from left to right. The guide limiting rod 508 and the protruding column structure of the dust cover 502 are respectively inserted into the two sets of deep holes of the terminal block 501, so that the dust cover 502 slides back and forth along the circular deep hole of the terminal block 501 through the protruding column and the guide limiting rod 508. The inner wall of the right deep hole of the terminal block 501 is provided with a groove.

[0030] In this embodiment, the guide limit rod 508 has a protrusion on its outer side. The protrusion structure on the outer side of the guide limit rod 508 is embedded in the groove of the inner wall of the deep hole on the right side of the terminal block seat 501. When the protrusion structure of the guide limit rod 508 extends out of the deep hole of the terminal block seat 501, the guide limit rod 508 drives the protrusion structure to rotate and disengage from the groove position of the inner wall of the deep hole on the right side of the terminal block seat 501, so that the guide limit rod 508 is stuck outside the deep hole on the right side of the terminal block seat 501, keeping the dust cover 502 in the open state, which facilitates the disassembly and assembly of the wires between the clamp 512 and the conductive contact 513.

[0031] In this embodiment, there are two sets of limiting and fixing plates 504, which are symmetrically distributed in the two sets of grooves of the terminal block seat 501. Each set of limiting and fixing plates 504 has two sets of inverted L-shaped protrusions on its upper side. Each set of limiting and fixing plates 504 has a threaded through hole at its center. The forward threaded end of the outer side of the bidirectional threaded rod 507 is engaged with the threaded through hole of the right limiting and fixing plate 504, and the reverse threaded end of the outer side of the bidirectional threaded rod 507 is engaged with the threaded through hole of the left limiting and fixing plate 504. The bidirectional threaded rod 507 drives the two sets of limiting and fixing plates 504 to move in opposite directions along the groove wall of the terminal block seat 501, so that the L-shaped protrusions are engaged with the left and right edges of the groove of the base 4 to lock the base 4, so that the electromagnetic relay is stably installed and fixed in the relay mounting wiring device 5 through the base 4.

[0032] In this embodiment, there are two sets of heat sinks 2. Each set of heat sinks 2 is tightly attached to the left and right sides of the transparent cover 1 by silicone thermal conductive pads 3. The surface of the heat sink 2 is densely covered with a large number of horizontally arranged fin structures. Through the air convection characteristics between the multiple sets of fins of the heat sink 2, the natural conduction and heat dissipation of heat inside the transparent cover 1 is accelerated.

[0033] In this embodiment, the upper side of the base 4 is provided with through grooves that run vertically through the front end and the end. The two sets of inverted L-shaped protrusions of the limiting and fixing plate 504 are respectively inserted into the through grooves of the base 4. The L-shaped protrusions of the limiting and fixing plate 504 move left and right in the through grooves of the base 4 to lock and release the base 4.

[0034] The specific usage and function of this embodiment are as follows: In this invention, when installing the electromagnetic relay on the terminal block, the bottom prongs of the electromagnetic relay 6 are first aligned with the insertion holes on the upper side of the terminal block base 501. At this time, the two sets of through slots on the upper side of the base 4, which is bolted to the bottom of the electromagnetic relay 6, align with the upper side of the inverted L-shaped protrusions of the limiting fixing plate 504. Then, the prongs of the electromagnetic relay 6 are inserted into the insertion holes on the upper side of the terminal block base 501. At this time, the inverted L-shaped protrusions of the two sets of limiting fixing plates 504 are respectively inserted into the two sets of through slots of the base 4. Afterward, the knob 506 is manually turned, which drives the bidirectional threaded rod 507 to rotate. Since the threaded through holes of the two sets of limiting fixing plates 504 are respectively engaged with the forward thread end and the reverse thread end on the outer side of the bidirectional threaded rod 507, the bidirectional thread... During rotation, rod 507 drives two sets of limiting and fixing plates 504 to move left and right in opposite directions along the two sets of grooves of terminal block seat 501 until the inner side of the L-shaped protrusion on the upper side of the limiting and fixing plate 504 is tightly fitted with the left and right edges of the through groove of the base 4, locking the base 4 at the inverted L-shaped protrusion of the limiting and fixing plate 504. The inverted L-shaped protrusion provides upper limit locking for the electromagnetic relay 6 bolted to the upper side of the base 4, preventing the electromagnetic relay 6 from coming out of the socket of the terminal block seat 501 due to vibration and collision. When wiring the terminal block, hold the outer side of the dust cover 502 with one hand and pull the dust cover 502. At this time, the guide limiting rod 508 connected to the dust cover 502 and the protrusion inside the groove structure of the dust cover 502 are rotated. Do not slide the guide rod 508 outward along the two sets of deep holes in the terminal block 501. When the protrusion structure on the outer side of the guide rod 508 is fully extended out of the groove in the right deep hole of the terminal block 501, turn the knob 506 with your other hand. The knob 506 will rotate the guide rod 508 180 degrees, so that the protrusion structure on the outer side of the guide rod 508 is completely disengaged from the groove in the right deep hole of the terminal block 501. Then, release the dust cover 502 with both hands. At this time, the protrusion on the outer side of the guide rod 508 will contact the outer side of the right deep hole of the terminal block 501, so that the guide rod 508 moves and limits the movement of the dust cover 502, keeping the dust cover 502 in the open state. Then, insert the external wire into the socket 503, and the wire end enters the dust cover 502. Inside the slot, place the connector of the external wire between the conductive contact 513 and the clamp 512. Then, tighten the clamping bolt 511. The nut of the clamping bolt 511 pushes the clamp 512, causing the conductive contact 513 and the clamp 512 to clamp and connect the connector of the external wire. Then, rotate the knob 506. The knob 506 drives the guide limit rod 508 to rotate, so that the protruding structure on the outer side of the guide limit rod 508 aligns with the groove in the deep hole on the right side of the terminal block seat 501. Then, release the knob 506. Under the pull of the spring 509, the protruding part of the dust cover 502 extends along the guide rod 510 into the deep hole on the left side of the terminal block seat 501. The protrusion on the outer side of the guide limit rod 508 slides inward along the groove in the deep hole on the right side of the terminal block seat 501.The guide limit rod 508 extends into the deep hole on the right side of the terminal block 501. At this time, the two sets of dust covers 502 are respectively attached to the front and rear sides of the terminal block 501, so that the dust covers 502 cover the terminals of the terminal block 501 for dust protection.
