Description

Technical Field

[0001] The utility model relates to the field of PLC control cabinets, in particular to a PLC control cabinet which is convenient for wiring. Background Art

[0002] PLC control cabinet refers to a programmable control cabinet. A control cabinet refers to a complete set of control cabinets, an electrical cabinet that can control motors and switches. PLC control cabinets have protection functions such as overload, short circuit, and phase loss protection.

[0003] PLC control cabinet generally includes the following five parts: air switch, PLC, power supply, relay and terminal block. The terminal block can be configured according to the number of signals. However, when the terminal block is used for wiring, the wires need to be connected to the terminal block. In the existing technology, a plurality of grooves are usually provided at intervals on the surface of the terminal block, and threaded holes are provided in the grooves. When wiring, the metal wire at one end of the wire is bent into a circle, and then the round metal wire is aligned with the threaded hole. Finally, the screw can be passed through the middle of the round metal wire and threadedly connected to the threaded hole. At this time, the wires can be installed one by one in the grooves on the surface of the terminal block. However, when multiple wires need to be installed or removed at the same time, this method is less efficient. Not only do the screws need to be installed or removed one by one, but a screwdriver is also needed during the installation and removal process, which is inconvenient to use.

[0004] Therefore, it is necessary to invent a PLC control cabinet that is easy to connect. Utility Model Content

[0005] The purpose of this utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a PLC control cabinet that is easy to wire, comprising a cabinet body and a cabinet door, the cabinet door being installed on the front of the cabinet body, a terminal block being installed in the inner cavity of the cabinet body, wiring grooves being spaced apart on the surface of the terminal block, a terminal post being fixedly installed in the middle of the inner cavity of the wiring groove, elastic clips being symmetrically installed on both sides of the front of the wiring groove, a limiting baffle being provided at the upper end of the wiring groove, and wires being movably connected inside the wiring groove.

[0007] Based on the above features: when wiring is required, the limit baffle can be pushed first to allow the terminal posts in the wiring slot to leak out, and then the wires can be connected to the terminal posts. Then the limit baffle can be loosened to limit the limit baffle above the wires and the terminal posts to prevent one end of the wire from separating from the terminal posts. At the same time, the elastic card can limit and clamp on both sides of the wire to keep the wire stable after connection.

[0008] Preferably, a telescopic slot is provided on a side of the wiring slot away from the elastic clamping plate, and a groove is provided at the middle upper end of the telescopic slot.

[0009] Based on the above features: the limit baffle can be telescopically adjusted through the telescopic slot. When the limit baffle is pushed out of the terminal, the limit baffle will shrink into the telescopic slot. When the limit baffle is released, the limit baffle will extend from the telescopic slot.

[0010] Preferably, the elastic clamping plate is arranged in an L-shaped structure, and the end face of the elastic clamping plate is arc-shaped.

[0011] Based on the above features, it is convenient for two symmetrical elastic clamps to perform position limiting clamping on both sides of the wire.

[0012] Preferably, a card slot is provided on one end surface of the elastic card plate.

[0013] Based on the above features: when the limit baffle extends from the telescopic slot, the end of the limit baffle away from the telescopic slot will be inserted into the inside of the card slot to prevent the limit baffle from flipping upward and improve the fixing effect.

[0014] Preferably, a protrusion is installed on the upper end of the side of the limit baffle away from the wiring slot, an anti-slip baffle is installed on the other side of the limit baffle, and a buffer spring is installed on the side of the anti-slip baffle away from the limit baffle.

[0015] Based on the above features: when the limit baffle is retracted into the telescopic slot, the limit baffle can be deformed by squeezing the buffer spring through the anti-slip baffle, and the protrusion can be limited inside the groove. When the protrusion is released, the buffer spring can automatically rebound the anti-slip baffle and the limit baffle.

[0016] Preferably, the limiting baffle and the anti-slip baffle are T-shaped structures.

[0017] Based on the above features: the anti-slip baffle and the buffer spring are displaced inside the telescopic slot, and the diameter of the anti-slip baffle is larger than the telescopic slot. When the limit baffle is rebounded, the limit baffle can be limited by the anti-slip baffle to prevent the limit baffle from completely detaching from the telescopic slot.

[0018] Preferably, a metal connector is provided at one end of the electric wire, and the metal connector is a hollow circular structure.

[0019] Based on the above features: the electric wire can be connected to the terminal by using the metal connector, and the elastic clamping plate can limit and clamp the electric wire near one end of the metal connector from both sides.

[0020] The beneficial effects of the utility model are:

[0021] 1. When wiring is required, you can first use the protrusion to push the limit baffle to retract into the telescopic slot so that the terminal in the wiring slot can leak out. At this time, the buffer spring will be squeezed and deformed, and then the metal connector at one end of the wire can be connected to the terminal. Then you can loosen the protrusion to make the buffer spring rebound the limit baffle. At this time, the limit baffle will be limited above the metal connector and the terminal, and there is no need to use screws to fix them one by one. When disassembly is required, just push the limit baffle again to retract into the telescopic slot, and then lift the metal connector upward to separate it from the terminal. It is simple and convenient to improve the efficiency of disassembly and assembly.

[0022] 2. The elastic clamp can limit and clamp the wires near one end of the metal connector from both sides. Since the end face of the elastic clamp is arc-shaped, the sharp end face of the elastic clamp can be prevented from damaging the wires. At the same time, when the buffer spring rebounds the limit baffle, the end of the limit baffle away from the telescopic slot will be inserted into the inside of the slot to prevent the limit baffle from flipping upward, thereby improving the fixing effect.

[0023] 3. The anti-offset baffle and the buffer spring are displaced inside the telescopic slot, and the diameter of the anti-offset baffle is larger than the telescopic slot. When the limit baffle is rebounded, the limit baffle can be limited by the anti-offset baffle to prevent the limit baffle from completely detaching from the telescopic slot when it is rebounded.

[0030] Refer to the attached Figure 1-4 The utility model provides a PLC control cabinet that is easy to wire, including a cabinet body 1 and a cabinet door 2. The cabinet door 2 is installed on the front of the cabinet body 1. A terminal block 3 is installed in the inner cavity of the cabinet body 1. Wiring slots 4 are spaced apart on the surface of the terminal block 3. A terminal post 5 is fixedly installed in the middle of the inner cavity of the wiring slot 4. Elastic card plates 6 are symmetrically installed on both sides of the front of the wiring slot 4. A limit baffle 7 is provided on the upper end of the wiring slot 4. An electric wire 8 is movably connected inside the wiring slot 4.

[0031] The terminal blocks 3 can be assembled together in two adjacent ones according to the length requirements, and then can be installed inside the cabinet 1. When wiring is needed, the limit baffle 7 can be pushed first to allow the terminal 5 in the wiring slot 4 to leak out, and then the wire 8 can be connected to the terminal 5. Then the limit baffle 7 can be loosened to limit the limit baffle 7 above the wire 8 and the terminal 5 to prevent one end of the wire 8 from separating from the terminal 5. At the same time, the elastic card 6 can limit and clamp on both sides of the wire 8 to keep the wire 8 stable after connection.

[0032] Preferably, a telescopic slot 41 is formed on a side of the wiring slot 4 away from the elastic clamping plate 6 , and a groove 42 is formed at the middle upper end of the telescopic slot 41 .

[0033] The limit baffle 7 can be telescopically adjusted through the telescopic slot 41. When the limit baffle 7 is pushed to leak out of the terminal 5, the limit baffle 7 will shrink into the telescopic slot 41. When the limit baffle 7 is released, the limit baffle 7 will extend from the telescopic slot 41.

[0034] Preferably, the elastic clamping plate 6 is arranged in an L-shaped structure, and the end surface of the elastic clamping plate 6 is arc-shaped.

[0035] It is convenient for the two symmetrical elastic clamps 6 to perform position limiting clamping from both sides of the wire 8. Since the end faces of the elastic clamps 6 are arc-shaped, the sharp ends of the elastic clamps 6 are prevented from damaging the wire 8.

[0036] Preferably, a slot 61 is formed on one end surface of the elastic clamping plate 6 .

[0037] When the limit baffle 7 is extended from the telescopic slot 41 , the end of the limit baffle 7 away from the telescopic slot 41 is inserted into the card slot 61 to prevent the limit baffle 7 from flipping upward, thereby improving the fixing effect.

[0039] The operator can push the limit baffle 7 to move through the protrusion 71. When the limit baffle 7 is retracted into the telescopic groove 41, the limit baffle 7 can be deformed by squeezing the buffer spring 73 through the anti-slip baffle 72. At the same time, the protrusion 71 can be limited to the inside of the groove 42. When the protrusion 71 is released, the buffer spring 73 can automatically rebound the anti-slip baffle 72 and the limit baffle 7.

[0040] Preferably, the limiting baffle 7 and the anti-slip baffle 72 are T-shaped structures.

[0041] The anti-slip baffle 72 and the buffer spring 73 are displaced inside the telescopic slot 41, and the diameter of the anti-slip baffle 72 is larger than the telescopic slot 41. When the limit baffle 7 is rebounded, the limit baffle 7 can be limited by the anti-slip baffle 72 to prevent the limit baffle 7 from completely detaching from the telescopic slot 41.

[0042] Preferably, a metal connector 81 is provided at one end of the electric wire 8 , and the metal connector 81 is a hollow circular structure.

[0043] The diameter of the metal connector 81 is larger than the diameter of the gap between the two elastic clamps 6. The wire 8 can be connected to the terminal 5 using the metal connector 81, and the elastic clamp 6 can limit and clamp the wire 8 near one end of the metal connector 81 from both sides.

[0044] The usage process of the present utility model is as follows: when wiring is needed, the protrusion 71 can be used first to push the limit baffle 7 to retract into the telescopic groove 41, so that the terminal 5 in the terminal groove 4 can leak out. At this time, the buffer spring 73 will be squeezed and deformed, and then the metal connector 81 at one end of the wire 8 can be connected to the terminal 5. At this time, the elastic card plate 6 can limit and clamp the wire 8 near one end of the metal connector 81 from both sides, and then the protrusion 71 can be released to allow the buffer spring 73 to rebound the limit baffle 7. At this time, the limit baffle 7 will be limited above the metal connector 81 and the terminal 5, and at the same time, the end of the limit baffle 7 away from the telescopic groove 41 will be inserted into the inside of the card slot 61 for fixation. When disassembly is required, just push the limit baffle 7 again to retract into the telescopic groove 41, and then lift the metal connector 81 upward to separate it from the terminal 5.
