Description

Technical Field

[0001] This utility model belongs to the field of power electronics technology, and more specifically, it relates to a frequency converter terminal block mounting structure. Background Technology

[0002] In modern industrial production and electric drive systems, frequency converters are the core equipment for realizing motor speed regulation and energy-saving control. The reliability of their terminal block installation structure directly affects the stability and safety of equipment operation. Existing frequency converter terminals are generally screw-type terminals, which are connected by tightening wires with bolts.

[0003] The existing application number is CN202322878926.8. This application belongs to the field of terminal block technology, and particularly relates to an installation structure for inverter terminal blocks, including a housing, a wire guide plate, and wire holes provided on the wire guide plate, and also includes a clamping mechanism. The clamping mechanism includes: a fastening bolt; a clamping plate, provided on the housing, and having threaded holes adapted to the fastening bolt; and a pressure plate, provided at the bottom of the fastening bolt and rotatably connected to the fastening bolt, and having multiple wire pressing grooves at the bottom of the pressure plate. The housing has a first through hole for the fastening bolt to pass through. The clamping plate and the housing are detachably connected, and the inner diameter of the first through hole is larger than the diameter of the fastening bolt. The beneficial effect of this application is that by rotating the fastening bolt, the pressure plate is gradually pressed down and clamps the wire to be fixed. Since the threaded holes are located on the clamping plate, and the clamping plate is a detachable structure, when the threads on the clamping plate are damaged, only the clamping plate needs to be replaced, without replacing the entire housing, effectively reducing losses.

[0004] Based on the above, existing methods generally require workers to pre-process the ends of the connecting wires before inserting them into the inverter terminals. For example, they need to twist the loose wire ends together. Only after pre-processing the connecting wires can they be connected, which makes the operation more cumbersome and affects the wiring efficiency of the inverter. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an inverter terminal block installation structure. This solves the problem that, in existing systems, workers typically need to pre-process the ends of the connecting wires before inserting them into the inverter terminals. For example, they need to twist the loose wire ends together. This pre-processing of the connecting wires before connection can be performed results in cumbersome operation and affects the wiring efficiency of the inverter.

[0006] The purpose and effect of this utility model's inverter terminal block installation structure are achieved through the following specific technical means:

[0007] A frequency converter terminal block mounting structure includes a frequency converter body, a wiring slot, a twisting fixing component, a twisting drive component, a twisting fixing disc, a twisting clamping rod, a wiring fixing mechanism, and a twisting drive mechanism. Multiple sets of wiring slots are provided, each located at the lower front end of the frequency converter body.

Multiple sets of twisting drive components are provided, each rotatably connected to the inner front of the twisting fixing component.

[0008] Furthermore, the wiring fixing mechanism includes: clamping contacts and clamping springs; multiple sets of clamping contacts are provided, and the multiple sets of clamping contacts are respectively fixedly connected to the inner side of the twisting clamping rod; multiple sets of clamping springs are provided, and the multiple sets of clamping springs are respectively fixedly connected to the outer side of the twisting drive member, and the outer side of the multiple sets of clamping springs is respectively fixedly connected to the twisting clamping rod.

[0009] Furthermore, the wiring fixing mechanism also includes a preliminary twisting member; the preliminary twisting member has a spiral protrusion structure and is fixedly connected to the inner side of the twisting drive member.

[0010] Furthermore, the twisting drive mechanism includes: a twisting drive slide, a twisting drive groove, and a twisting drive slider; the twisting drive slide is slidably connected to the outer periphery of the twisting fixing member; the twisting drive groove is a curved guide groove structure, and the twisting drive groove is opened on the outer periphery of the twisting drive member; the inner side of the twisting drive slider is disposed inside the twisting drive groove, and the twisting drive slider is fixedly connected to the inner side of the twisting drive slide.

[0011] Furthermore, the twisting drive mechanism also includes: a twisting guide plate, a twisting support spring, a twisting connecting rod, a first twisting block, and a second twisting block; the twisting guide plate is slidably connected to the rear of the outer periphery of the twisting fixing member; the twisting support spring is fixedly connected to the front end of the twisting fixing plate, and the front end of the twisting support spring is fixedly connected to the twisting guide plate; multiple sets of twisting connecting rods are provided, each set being fixedly connected to the front end of the twisting guide plate, and each set of twisting connecting rods is slidably connected to the twisting drive slide plate; multiple sets of first twisting blocks are provided, each set being fixedly connected to the front end of the twisting connecting rod; multiple sets of second twisting blocks are provided, each set being fixedly connected to the outer side of the twisting clamping rod, and the second twisting blocks and the first twisting blocks together form a wedge structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model, through the setting of the wiring fixing mechanism, inserts the wire into the inside of the stranding drive component. At this time, the spiral structure of the initial stranding component causes the wire to move backward along the initial stranding component, thereby guiding the wire and enabling the wire to undergo initial stranding. At the same time, after the wiring is completed, under the action of the clamping spring, the clamping contact component clamps the wire, improving the connection strength of the wire and ensuring the stability of the frequency converter.

[0015] This invention utilizes a stranding drive mechanism. When a wire is inserted into the inner side of the stranding drive component, the stranding drive slide moves backward, causing the stranding drive slider to move backward as well. Under the action of the stranding drive groove, the stranding drive component is rotated. This rotation causes the second stranding block and the first stranding block to shift, allowing the clamping contact to hold the wire. As the stranding drive component rotates, the wire is stranded, eliminating the need for pre-processing and improving the efficiency of inverter wiring. Attached Figure Description

[0029] The specific usage and function of this embodiment are as follows: When wiring, the wire is inserted into the inside of the twisting drive 4. At this time, the spiral structure of the preliminary twisting member 103 causes the wire to move backward along the preliminary twisting member 103, which guides the wire and allows the wire to be initially twisted. At the same time, after the wiring is completed, under the action of the clamping spring 102, the clamping contact 101 clamps the wire, which improves the connection strength of the wire and ensures the stability of the frequency converter.

[0030] Example 2:

[0031] This utility model provides a frequency converter terminal block mounting structure, based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a twisting drive mechanism, and multiple sets of twisting drive mechanisms are provided, with each set of twisting drive mechanisms being disposed on the outside of the twisting fixing member 3.

[0032] The twisting drive mechanism includes a twisting drive slide 501, a twisting drive groove 502, and a twisting drive slider 503. The twisting drive slide 501 is slidably connected to the outer periphery of the twisting fixing member 3.

[0033] The twisting drive mechanism further includes: a twisting guide disc 504, a twisting support spring 505, a twisting connecting rod 506, a first twisting block 507, and a second twisting block 508; the twisting guide disc 504 is slidably connected to the rear of the outer periphery of the twisting fixing member 3; the twisting support spring 505 is fixedly connected to the front end of the twisting fixing disc 5, and the front end of the twisting support spring 505 is fixedly connected to the twisting guide disc 504; multiple sets of twisting connecting rods 506 are provided. 06 are fixedly connected to the front end of the twisting guide plate 504, and multiple sets of twisting connecting rods 506 are slidably connected to the twisting drive slide plate 501; multiple sets of first twisting blocks 507 are provided, and multiple sets of first twisting blocks 507 are fixedly connected to the front end of the twisting connecting rods 506; multiple sets of second twisting blocks 508 are provided, and multiple sets of second twisting blocks 508 are fixedly connected to the outside of the twisting clamping rod 6, and the second twisting blocks 508 and the first twisting blocks 507 together form a wedge structure.

[0035] The specific usage and function of this embodiment are as follows: When connecting wires, the wires are inserted into the inner side of the stranding drive member 4. At this time, the stranding drive slide 501 is moved backward. The backward movement of the stranding drive slide 501 drives the stranding drive slider 503 to move backward. Under the action of the stranding drive groove 502, the stranding drive member 4 is driven to rotate. The rotation of the stranding drive member 4 causes the second stranding block 508 and the first stranding block 507 to shift. At this time, the clamping contact member 101 clamps the wires. As the stranding drive 4 rotates, the wires are stranded, avoiding pre-processing and improving the efficiency of inverter wiring. The stranding drive slide 501 continues to move backward, causing the stranding reset block 509 to contact the stranding contact block 510. At this time, the first stranding block 507 is reset and the first stranding block 507 presses the second stranding block 508 outward. The wire is no longer held by the clamping contact 101. The worker then inserts the stranded wire into the wiring slot 2 to connect the wires.
