Description

Technical Field

[0001] This invention relates to the technical field of controllers, specifically to a controller for a low-dropout linear constant current drive circuit. Background Technology

[0002] In practical applications of low-dropout linear constant current drive controllers, to meet the requirements of moisture-proof, dust-proof, and electromagnetic shielding, the controller often needs to be integrated and installed in a metal enclosure. The controller's output / input pins are first connected to the terminal block via internal wires through soldering or plugging. External wires are then passed through the pre-set wire holes in the metal enclosure and secured to the corresponding interfaces of the terminal block. There is an inherent conflict between the "space constraints" of the metal enclosure and the "convenience of wire connection operation". Existing external wire connection schemes for low-dropout linear constant current drive controllers in metal enclosures (where space is limited) generally suffer from time-consuming and laborious operation and low connection reliability. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a controller for a low-dropout linear constant current drive circuit, which has advantages such as increasing the operating space and improving the work efficiency of staff, and solves the problems of time-consuming and labor-intensive operation and low connection reliability.

[0004] To achieve the aforementioned goal of increasing operating space and improving worker efficiency, this invention provides the following technical solution: a controller for a low-difference linear constant current drive circuit, comprising a housing and a body, with a base block located below the body and fixedly installed inside the housing. The base block has three sets of sliding grooves, each set containing three grooves. Three vertical grooves are located on the right side of the base block, with each sliding groove communicating with each vertical groove. An L-shaped plate a is movably connected within each sliding groove, and a connector is fixedly installed within each L-shaped plate a. A square strip is fixedly installed on each L-shaped plate a, and a through groove is formed on each square strip. A wire groove is also formed on each L-shaped plate a.

[0005] Preferably, two limiting blocks are fixedly installed on each L-shaped plate a, and protrusions are fixedly installed on the front and rear inner walls of each groove, with each protrusion respectively fitting with two L-shaped plates a.

[0006] Preferably, a first L-shaped baffle is fixedly installed in each of the vertical slots, a second L-shaped baffle is provided outside each first L-shaped baffle, and a third L-shaped baffle is provided outside each second L-shaped baffle.

[0007] Preferably, each of the second L-shaped baffles and each of the third L-shaped baffles are fixedly installed in the three vertical slots, with the first L-shaped baffle being shorter than the second L-shaped baffle and the second L-shaped baffle being shorter than the third L-shaped baffle.

[0008] Preferably, three L-shaped plates b are fixedly installed on the front of the base block, and a horizontal plate a is fixedly installed inside each of the three L-shaped plates b. A horizontal plate b is provided below each horizontal plate a.

[0009] Preferably, each of the horizontal plates a is shorter than each of the horizontal plates b, each horizontal plate b is fixedly connected to each L-shaped plate b, and the outer shell sidewall is provided with three sets of slots.

[0010] Compared with the prior art, this invention provides a controller for a low-dropout linear constant current drive circuit, which has the following advantages:

[0011] 1. The controller of this low differential pressure linear constant current drive circuit connects the wires to the connection points on the machine body, and then passes the wires through the vertical slots and each through slot. This allows the wires to be connected to the connectors. When external circuits need to be connected to the machine body, there is no need to connect them to the connection points; only the connectors need to be connected. The connectors are located inside the L-shaped plate a, and the L-shaped plate can be pulled out for connection. This increases the operating space and speeds up the work efficiency of the staff, thus solving the problems of time-consuming and laborious operation and low connection reliability.

[0012] 2. The controller of this low differential linear constant current drive circuit can limit the distance that the L-shaped plate b is pulled out to prevent it from falling off through the protrusion and the limit block. At the same time, the space in the vertical groove can be separated by the first L-shaped baffle, the second L-shaped baffle and the third L-shaped baffle, so that the wires connecting different connectors can be separated, thus making it convenient for users to sort them.

[0013] 2. The controller of this low differential linear constant current drive circuit allows wires to be inserted into the housing through slots. The L-shaped plate b, together with the horizontal plate a and the horizontal plate b, can separate the space. By passing through different slots, the wires will enter different gaps, thus separating the external wires for easy management and maintenance by staff. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 The present invention provides a technical solution: a controller for a low differential pressure linear constant current drive circuit, comprising a housing 1 and a body 2. A bottom block 3 is provided below the body 2 and is fixedly installed inside the housing 1. The bottom block 3 has three sets of sliding grooves 6, each set of sliding grooves 6 having three sliding grooves 6. Three vertical grooves 21 are provided on the right side of the bottom block 3. Each sliding groove 6 is connected to each vertical groove 21. An L-shaped plate a9 is movably connected in each sliding groove 6. A connector 18 is fixedly installed in each L-shaped plate a9. A square strip 14 is fixedly installed on each L-shaped plate a9. A through groove 15 is provided on each square strip 14. A wire groove 10 is provided on each L-shaped plate a9.

[0023] By connecting the wires to the connection points on the machine body 2, and then passing the wires through the vertical slots 21 and each through slot 15, the wires can be connected to the connector 18. This way, when it is necessary to connect external circuits to the machine body 2, it is not necessary to connect to the connection points, but only to the connector 18. The connector 18 is located inside the L-shaped plate a9, and the connection can be made by pulling out the L-shaped plate 9, which can increase the operating space and speed up the work efficiency of the staff.

[0024] Two limiting blocks 16 are fixedly installed on each L-shaped plate a9. Protrusions 19 are fixedly installed on the front and rear inner walls of each slide groove 6. Each protrusion 19 is in contact with the two L-shaped plates a9 respectively. The protrusions 19 and the limiting blocks 16 are set at the same level. In this way, when the L-shaped plate 9 is pulled and the limiting blocks 16 are moved to a certain distance, they will be blocked by the protrusions 19.

[0025] Each vertical groove 21 is fixedly installed with a first L-shaped baffle 11, a second L-shaped baffle 12 is provided outside each first L-shaped baffle 11, and a third L-shaped baffle 13 is provided outside each second L-shaped baffle 12.

[0026] Each second L-shaped baffle 12 and each third L-shaped baffle 13 are respectively fixedly installed in three vertical slots 21. The first L-shaped baffle 11 is shorter than the second L-shaped baffle 12, and the second L-shaped baffle 12 is shorter than the third L-shaped baffle 13.

[0027] The protrusion 19 and the limiting block 16 can limit the distance that the L-shaped plate b9 is pulled out to prevent it from falling off. At the same time, the first L-shaped baffle 11, the second L-shaped baffle 12 and the third L-shaped baffle 13 can separate the space in the vertical groove 21, so that the wires connecting different connectors 13 can be separated, making it convenient for users to sort them.

[0028] Three L-shaped plates b4 are fixedly installed on the front of the bottom block 3. A horizontal plate a8 is fixedly installed inside each of the three L-shaped plates b4. A horizontal plate b7 is set below each horizontal plate a8.

[0029] Each horizontal plate a8 is shorter than each horizontal plate b7, and each horizontal plate b7 is fixedly connected to each L-shaped plate b4. The outer shell 1 has three sets of slots 5 on its side wall.

[0030] The wires can be inserted into the outer casing 1 through the slot 5. The L-shaped plate b4, together with the horizontal plate a8 and the horizontal plate b7, can separate the space. By passing through different slots 5, the wires will enter different gaps, thus separating the external wires for easy management and maintenance by the staff.

When it is necessary to connect external circuits to the machine body 2, it is not necessary to connect to the connection points; it is only necessary to connect to the connector 18. The connector 18 is located inside the L-shaped plate a9, and the connection can be made by pulling out the L-shaped plate 9. This increases the operating space and speeds up the work efficiency of the staff.

[0051] Step 2: The protrusion 19 and the limiting block 16 can limit the distance that the L-shaped plate b9 is pulled out to prevent it from falling off. At the same time, the first L-shaped baffle 11, the second L-shaped baffle 12 and the third L-shaped baffle 13 can separate the space in the vertical groove 21, so that the wires connecting different connectors 13 can be separated, making it convenient for the user to sort them.
