Description

Technical Field

[0001] This utility model relates to the field of electronic building block components technology, specifically to a building block relay device. Background Technology

[0002] A relay is an automatic switching device that uses a small current to control a large current. It achieves circuit isolation, switching, protection, and control through electromagnetic principles or other means. Modular relays refer to relay systems that employ a modular, pluggable design and are mounted on standardized bases / DIN rails. This greatly simplifies the installation, configuration, expansion, and maintenance of relays.

[0003] Existing relay modules are mostly independent PCB board-based with fixed dimensions, making them difficult to integrate with modular structures. Consequently, relay modules cannot be directly embedded into standard modular building systems and require additional fasteners for installation. This results in poor compatibility between relay modules and modular modules, making it difficult to quickly integrate them into modular building systems. Utility Model Content

[0004] The purpose of this invention is to provide a modular relay device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular relay device, comprising a first housing, a second housing, and a circuit board. The second housing is connected to the top of the outer wall of the first housing, and the circuit board is connected to the inside of the first housing via a column. A Type-C interface is installed on one side of the top of the circuit board, and a control switch is connected to the other side of the top of the circuit board. A horizontal pin seat is connected to the middle of the circuit board, and a modular hole is fixedly connected to the top of the second housing.

[0006] By aligning the block holes on the outer wall of the second casing with the block components, the relay module can be installed on the block components, thus allowing it to be directly embedded into the standard block building system without the need for additional fasteners.

[0007] Preferably, the horizontal pin holder is provided with three sets connected in parallel, and the outer walls of the first and second outer shells are each provided with a side through hole corresponding to the Type-C interface.

[0008] Preferably, the top two sides of the first outer shell are fixedly connected with snap-fit ​​parts, and the bottom two sides of the second outer shell are provided with snap-fit ​​grooves corresponding to the snap-fit ​​parts.

[0009] By moving the second housing, the snap-fit ​​part snaps into both sides of the bottom of the second housing. At this time, the second housing and the snap-fit ​​part are engaged, which can limit and fix the first housing and the second housing, thereby quickly completing the assembly of the relay housing.

[0010] Preferably, a support column is fixedly connected to the middle of the bottom end of the first outer casing, and a threaded rod is threadedly connected inside the support column. A through hole corresponding to the support column is opened inside the circuit board.

[0011] Preferably, a limiting groove is provided at the bottom end of the threaded rod, and the limiting groove has a "+" shaped structure, and an ejector block is fixedly connected to the top end of the threaded rod.

[0012] By inserting a Phillips screwdriver or similar tool into the limiting groove and rotating the threaded rod, the movement of the threaded rod will cause the ejector block to move along with it until the ejector block contacts the second outer shell and exerts a pushing force on it, thereby causing the second outer shell to move upward and separate from the first outer shell.

[0013] Preferably, the bottom of the outer wall of the first outer shell is fixedly connected to an equally spaced base, and the top of the base is connected to slide rails on both sides, the slide rails having a "T" shaped structure.

[0014] Preferably, a baffle is slidably connected to the outer wall of the slide rail, and a metal fixing strip is fixedly connected to the top of the baffle. The baffle has an "L" shape, and the baffle and the metal fixing strip have a "C" shape.

[0015] The baffle moves smoothly by being guided by a slide rail, and the movement of the baffle will cause the metal fixing strip to move together.

[0016] Preferably, both sides of the baffle and the metal fixing strip are provided with grooves corresponding to the slide rail, and one side of the outer wall of the slide rail is fixedly connected to the first outer shell. The top of the metal fixing strip is magnetically connected to a magnet, and one side of the outer wall of the magnet is fixedly connected to the second outer shell.

[0017] By pushing the baffle upwards, the baffle slides along the slide rail at the top of the base until the baffle causes the metal fixing strip to come into contact with the magnet. At this point, the magnet and the metal fixing strip are magnetically connected, thus limiting the baffle and preventing it from moving further.

[0018] As can be seen from the above, the modular relay device provided by this utility model has the following beneficial effects.

[0019] Simply align the block holes with the block components to install the relay module onto the block components. This allows it to be directly embedded into the standard block building system without the need for additional fasteners, thus improving the compatibility between the relay module and the block modules.

[0020] By rotating the threaded rod, the ejector block comes into contact with the second housing, thereby generating a thrust on it. This causes the second housing to move upward and separate from the first housing, making it easier for people to separate the relay housing for internal inspection.

[0021] The limit baffle prevents it from moving further. At this time, the baffle covers the horizontal pin holder, thereby protecting the horizontal pin holder and preventing it from being damaged by contact with external debris. 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 Figures 1-12The present invention provides a technical solution: a modular relay device, comprising a first outer shell 1, a second outer shell 2, and a circuit board 3. The second outer shell 2 is connected to the top of the outer wall of the first outer shell 1, and the circuit board 3 is connected to the inside of the first outer shell 1 through a column. A Type-C interface 4 is installed on one side of the top of the circuit board 3, and a control switch 5 is connected to the other side of the top of the circuit board 3. A horizontal pin holder 6 is connected to the middle of the circuit board 3. A modular hole 7 is fixedly connected to the top of the second outer shell 2. Three sets of horizontal pin holders 6 are provided and connected in parallel to each other. A side through hole corresponding to the Type-C interface 4 is opened on one side of the outer wall of both the first outer shell 1 and the second outer shell 2.

[0026] In practice, since the top of the second outer shell 2 is connected to the building block hole 7, the operator only needs to move the first outer shell 1 so that the building block hole 7 on the outer wall of the second outer shell 2 can be connected with the building block component. The relay module can then be installed on the building block component, and can be directly embedded into the standard building block system without the need for additional fasteners to assist in the installation, thus improving the compatibility between the relay module and the building block module. Next, connect the device charging cable to the Type-C interface 4 on the top of the circuit board 3. The Type-C interface 4 supports reversible insertion. Then, connect the negative power supply wire to the horizontal pin socket 6. At this time, the negative power supply wire is connected to the negative terminal of the Type-C interface 4 and the negative terminal of the relay circuit, forming a parallel grounding path. Connect the positive power supply wire to the horizontal pin socket 6. At this time, the positive power supply wire is connected to the positive terminal of the Type-C interface 4 and the relay power supply terminal, constructing a parallel power supply circuit. Connect the relay signal control terminal wire to the horizontal pin socket 6. At this time, the relay signal control terminal is connected to the switch output and the relay control circuit, realizing multi-channel parallel signal triggering, thereby providing balanced power supply to the relay module.

[0027] Finally, manually toggle control switch 5, or input a high-level signal to the parallel needle socket signal control terminal through an external circuit to trigger the relay contacts to close or open. Because the needle sockets are connected in parallel, multi-channel parallel trigger control is achieved, which is suitable for multi-load synchronous on / off scenarios.

[0028] See Figures 4-10 The first outer shell 1 has a snap-fit ​​part 8 fixedly connected to both sides of its top end, and the second outer shell 2 has snap-fit ​​grooves corresponding to the snap-fit ​​part 8 on both sides of its bottom end; the first outer shell 1 has a support column 9 fixedly connected to the middle of its bottom end, and the support column 9 has a threaded rod 10 threadedly connected inside; the circuit board 3 has a through hole corresponding to the support column 9 inside; the bottom end of the threaded rod 10 has a limit groove 11, and the limit groove 11 has a "+" shaped structure; the top end of the threaded rod 10 has an ejector block 12 fixedly connected to it.

[0029] In practice, since the top two sides of the first housing 1 are fixedly connected with the snap-fit ​​parts 8, the staff only needs to move the second housing 2 so that the snap-fit ​​parts 8 snap into the bottom two sides of the second housing 2. At this time, the second housing 2 and the snap-fit ​​parts 8 are engaged, which can limit and fix the first housing 1 and the second housing 2, thereby quickly completing the assembly of the relay housing.

[0030] When it is necessary to separate housing 1 and housing 2, first insert a Phillips screwdriver or other tools into the limiting groove 11, then rotate the threaded rod 10 to move it upward along the support column 9. The movement of the threaded rod 10 will drive the ejector block 12 to move together until the ejector block 12 contacts housing 2 and generates a pushing force on it, thereby causing housing 2 to move upward and separate from housing 1, thus making it convenient for people to separate the relay housing for internal maintenance.

[0031] See Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 11 and Figure 12 The bottom of the outer wall of the first outer shell 1 is fixedly connected to an equally spaced base 13, and the top of the base 13 is connected to two sides of a slide rail 14, which has a "T" shape. The outer wall of the slide rail 14 is slidably connected to a baffle 15, and the top of the baffle 15 is fixedly connected to a metal fixing strip 16, which has an "L" shape. The baffle 15 and the metal fixing strip 16 have a "C" shape. The baffle 15 and the metal fixing strip 16 have grooves on both sides inside that correspond to the slide rail 14. The outer wall of the slide rail 14 is fixedly connected to the first outer shell 1. The top of the metal fixing strip 16 is magnetically connected to a magnet 17, and the outer wall of the magnet 17 is fixedly connected to the second outer shell 2.

[0032] In practice, the baffle 15 is first pushed upwards, causing it to slide along the slide rail 14 at the top of the base 13. The slide rail 14 guides the baffle 15 to move smoothly until the baffle 15 causes the metal fixing strip 16 to contact the magnet 17. At this point, the magnet 17 and the metal fixing strip 16 are magnetically connected, thus limiting the baffle 15 to prevent it from moving further. The baffle 15 also covers the horizontal pin holder 6, thus protecting it from contact with external debris and damage. After that, people only need to press the baffle 15 to disengage the metal fixing strip 16 from the magnet 17, which will reveal the horizontal pin holder 6.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
