Description

Technical Field

[0001] This utility model belongs to the technical field of industrial DC power supply cabinet terminal block assembly, specifically relating to an industrial DC power supply cabinet terminal block assembly with multi-circuit quick wiring. Background Technology

[0002] Terminal block assemblies in industrial DC power supply cabinets are core components for circuit connections and signal transmission in power systems, undertaking crucial functions such as current distribution, line switching, and safety protection. These assemblies typically consist of an insulating base, conductive terminals, fastening screws, and identification plates. The conductive terminals are mostly made of high-conductivity copper alloys, with tin-plated or gold-plated surfaces to ensure low contact resistance and good oxidation resistance. The insulating base is made of high-temperature resistant, arc-resistant reinforced nylon or epoxy resin, possessing excellent electrical insulation and mechanical strength. Terminal blocks can be functionally categorized into power terminals, signal terminals, and grounding terminals, and their standardized design enables modular installation, facilitating future maintenance and expansion. The assemblies are also equipped with dust covers and baffles to effectively prevent accidental contact and foreign object intrusion, improving operational safety. In the fields of power, communication, and industrial automation, terminal block assemblies provide reliable connection guarantees for the stable operation of DC power systems.

[0003] Currently, existing industrial DC power supply cabinet terminal block assemblies typically use snap-fit ​​connectors for connection and fixation during use. However, the stability of connectors fixed by a single snap-fit ​​in industrial DC power supply cabinet terminal block assemblies is poor, which may lead to the detachment of multi-circuit quick-connect wiring during subsequent use, thereby reducing the stability of the assembly for later use of multi-circuit quick-connect wiring. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-circuit quick-connection industrial DC power cabinet terminal block assembly, which aims to solve the problem that existing industrial DC power cabinet terminal block assemblies usually use a snap-fit ​​method to fix the connectors during use. However, the connectors fixed by a single snap-fit ​​are not very stable and may cause the multi-circuit quick-connection to fall off during subsequent use, thereby reducing the stability of the assembly in the later use of multi-circuit quick-connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terminal block assembly for a multi-circuit quick-connection industrial DC power supply cabinet, comprising a terminal block body, wherein the top of the terminal block body has rectangularly distributed insertion slots, a terminal connector is inserted into the insertion slot, one end of the terminal connector is connected to a connecting wire harness, a limit slot is formed on the outer wall of the terminal connector, and a plurality of first mounting slots are symmetrically distributed inside the terminal block body, a first spring is provided inside the plurality of first mounting slots, a movable block is connected to the end of the first spring, a limit pin is fixedly connected to one end of the movable block, and a toggle block is connected to the top of the movable block.

[0006] As a preferred embodiment of the multi-circuit quick wiring industrial DC power supply cabinet terminal block assembly of this utility model, one end of the limiting pin extends through into the interior of the plug slot.

[0007] As a preferred embodiment of the multi-circuit fast wiring industrial DC power cabinet terminal block assembly of this utility model, the end of the limiting pin away from the movable block is adapted to the size of the limiting slot. The terminal block body can form an elastic engagement structure with the terminal connector through the plug slot, the limiting slot, the first mounting slot, the first spring, the movable block, the limiting pin, and the toggle block.

[0008] As a preferred embodiment of the multi-circuit quick wiring industrial DC power cabinet terminal block assembly of this utility model, the outer wall of the terminal connector is provided with a snap-fit ​​groove, the inner wall of the plug groove is provided with a spring slot, and a metal spring is installed inside the spring slot.

[0009] In a preferred embodiment of the multi-circuit quick-connection industrial DC power supply cabinet terminal block assembly of this utility model, the protruding end of the metal spring is located inside the snap-fit ​​groove.

[0010] As a preferred embodiment of the multi-circuit fast wiring industrial DC power supply cabinet terminal block assembly of this utility model, the terminal block body has a second mounting groove inside, the second mounting groove is provided with a second spring, one end of the second spring is connected to a limit block, and one end of the limit block is connected to a top block.

[0011] As a preferred embodiment of the multi-circuit fast wiring industrial DC power supply cabinet terminal block assembly of this utility model, one end of the top block extends through into the insertion slot, and the top block can form an elastic structure with the terminal block body through the second mounting slot, the second spring, and the limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By inserting the terminal connector into the insertion slot, the beveled angle of the terminal connector and the limit pin will push the limit pin open and squeeze the first spring when the terminal connector is inserted until the terminal connector is inserted to the deepest point. At this time, the limit pin will pop out under the action of the first spring and insert into the limit slot on the outer wall of the terminal connector. At the same time, the metal spring piece squeezed by the force will embed its protruding end into the buckle groove after the terminal connector is fully inserted. Thus, the stability of multi-circuit fast wiring can be improved through the double fixing structure.

[0013] Through the elastic structure between the top block and the terminal block body, when the movable block is moved by the toggle block to retract the limit pin, one end of the limit pin will disengage from the limit slot. At this time, the compressed second spring can drive the limit block to reset, so that the top block can push the terminal connector out of the insertion slot, thereby facilitating subsequent maintenance and removal.

[0016] 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.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: a terminal block assembly for a multi-circuit fast wiring industrial DC power cabinet, comprising a terminal block body 1, a rectangular distribution of insertion slots 2 on the top of the terminal block body 1, a terminal connector 3 inserted into the insertion slot 2, a connecting wire harness 4 connected to one end of the terminal connector 3, a limit slot 5 formed on the outer wall of the terminal connector 3, a plurality of first mounting slots 6 symmetrically distributed inside the terminal block body 1, a first spring 7 disposed inside the plurality of first mounting slots 6, a movable block 8 connected to the end of the first spring 7, a limit pin 9 fixedly connected to one end of the movable block 8, and a toggle block 10 connected to the top of the movable block 8.

[0018] Preferably, one end of the limiting pin 9 extends through the interior of the insertion groove 2, and the end of the limiting pin 9 away from the movable block 8 is adapted to the size of the limiting groove 5. The terminal block body 1 can form an elastic engagement structure with the terminal connector 3 through the insertion groove 2, the limiting groove 5, the first mounting groove 6, the first spring 7, the movable block 8, the limiting pin 9, and the toggle block 10. The outer wall of the terminal connector 3 is provided with a snap-fit ​​groove 11, and the inner wall of the insertion groove 2 is provided with a spring groove 12. A metal spring 13 is installed inside the spring groove 12, and the protruding end of the metal spring 13 is located inside the snap-fit ​​groove 11.

[0019] In practical use, by inserting the terminal connector 3 into the insertion slot 2, the beveled angle of the terminal connector 3 and the limit pin 9 at the end will push the limit pin 9 open and squeeze the first spring 7 when the terminal connector 3 is inserted until the terminal connector 3 is inserted to the deepest point. At this time, the limit pin 9 will pop out under the action of the first spring 7 and insert into the limit slot 5 on the outer wall of the terminal connector 3. At the same time, the metal spring 13, which is squeezed by force, will have its protruding end embedded in the buckle slot 11 after the terminal connector 3 is fully inserted. Thus, the stability of multi-circuit fast wiring can be improved through the double fixing structure.

[0020] Preferably, the terminal block body 1 has a second mounting groove 14 inside, and a second spring 15 is provided inside the second mounting groove 14. One end of the second spring 15 is connected to a limiting block 16, and one end of the limiting block 16 is connected to a top block 17. One end of the top block 17 extends through into the insertion groove 2, and the top block 17 can form an elastic structure with the terminal block body 1 through the second mounting groove 14, the second spring 15, and the limiting block 16.

[0021] In practical use, through the elastic structure between the top block 17 and the terminal block body 1, when the movable block 8 is moved by the toggle block 10 to retract the limit pin 9, one end of the limit pin 9 will disengage from the limit slot 5. At this time, the compressed second spring 15 can drive the limit block 16 to reset, so that the top block 17 can push the terminal connector 3 out of the insertion slot 2, which is convenient for subsequent maintenance.

[0022] Working principle: First, insert the terminal connector 3 into the insertion slot 2. Utilizing the angled ends of the terminal connector 3 and the limiting pin 9, when the terminal connector 3 is inserted, it will push open the limiting pin 9 and squeeze the first spring 7 until the terminal connector 3 is inserted to its deepest point. At this time, the limiting pin 9 will pop out under the action of the first spring 7 and insert into the limiting slot 5 on the outer wall of the terminal connector 3. At the same time, the metal spring 13, which is compressed by force, will have its protruding end embedded in the buckle slot 11 after the terminal connector 3 is fully inserted. Thus, the stability of multi-circuit quick wiring can be improved through the double fixing structure. During disassembly, through the elastic structure between the top block 17 and the terminal block body 1, when the movable block 8 is moved by the toggle block 10 to retract the limiting pin 9, one end of the limiting pin 9 will disengage from the limiting slot 5. At this time, the compressed second spring 15 can drive the limiting block 16 to reset, so that the top block 17 can push the terminal connector 3 out of the insertion slot 2, thereby facilitating subsequent maintenance and removal.
