Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology for frequency converters, specifically to an anti-pull fixing component for air conditioner frequency converter cables. Background Technology

[0002] Air conditioning inverters typically consist of core components such as power units, phase-shifting transformers, and control systems, all housed within a cabinet. In the inverter's electrical connection layout, low-voltage secondary cables are often secured to the mounting plate using plastic binding wires to ensure reliable connections to various systems. However, during actual inverter operation, the cabinet continuously generates heat due to the operation of components like the power units. This continuous heat generation negatively impacts the effectiveness of the plastic binding wires, causing their stability to gradually decline. Furthermore, the operation of the cooling fan during inverter operation causes airflow within the cabinet, leading to slight cable movement. Prolonged friction between the cables and the plastic binding wires gradually damages the cable insulation, affecting not only the cable's performance but also posing serious safety hazards. Therefore, to ensure the stability and safety of the inverter, specialized securing components are required for cable positioning and fixation.

[0003] However, existing cable fixing components have revealed certain shortcomings in practical applications. Although these fixing components can limit and fix the cables, effectively preventing cable swaying, they are significantly inadequate in protecting the connectors. Specifically, existing fixing components cannot properly protect the connectors, which are prone to bending or loosening during use. Bending or loosening of the connectors can easily lead to damage, poor contact, and affect the normal operation of the frequency converter. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-pull fixing component for air conditioner inverter cables to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-pull fixing component for air conditioner inverter cables, including a mounting plate, the mounting plate being fixedly mounted on a housing, a positioning component being provided on the mounting plate, a fastening component matching the positioning component being provided on the mounting plate, anti-pull components being provided at equal intervals on the housing, and two adjacent anti-pull components being connected by a limiting mechanism.

Both the fixed clamping plate and the inner arc surface of the fixed clamping plate are provided with rubber pads.

[0007] Preferably, in order to facilitate the clamping and positioning of the connector, protect the connector from bending or loosening, ensure service life, and prevent poor contact, the fastening assembly includes an adjusting block fixedly installed under the moving plate. The mounting plate has an adjusting groove that slides with the adjusting block. The adjusting block is threaded with a fastening bolt, and the end of the fastening bolt has an internal hexagonal hole.

[0008] Preferably, in order to facilitate the clamping and fixing of the cable as a whole and prevent shaking, the anti-pull component includes a fixing seat set on the housing, and the fixing seat is symmetrically provided with arc-shaped fixing rings through elastic sheets, and the inner arc surface of the arc-shaped fixing ring is provided with anti-slip pads.

[0009] Preferably, in order to ensure the fixing effect by plugging in after the cable is initially clamped, the limiting mechanism includes a fixing plate set at the end of the arc-shaped fixing ring away from the elastic sheet. The fixing plate has plug-in holes, and plug-in pins are inserted into the two plug-in holes on the same fixing plate.

[0010] Preferably, in order to further limit and fix adjacent anti-pull components and ensure the clamping and fixing effect on the cable, the limiting mechanism also includes limiting holes opened on two adjacent plug pins, and a limiting rod is provided in the limiting holes.

[0011] Preferably, in order to ensure the insertion effect between the limiting rod and the limiting hole and to avoid slippage, a rubber sleeve is provided on the outside of the limiting rod, and the rubber sleeve is interference-fitted with the limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In terms of connector protection, this component achieves effective clamping and positioning of the connector through the synergistic action of the positioning component and the fastening component. The cooperation between the fixed plate and the moving plate, combined with the buffer protection of the rubber pad, effectively prevents the connector from bending or loosening during use, thereby ensuring the integrity and contact stability of the connector, extending the service life of the cable and connector, and reducing the risk of failure caused by poor contact.

[0014] The cable is fully clamped and secured by the anti-pull components equidistantly arranged on the housing. The arc-shaped fixing ring and elastic plate in the anti-pull components allow for easy cable insertion and tight fixation after placement, effectively preventing cable shaking and pulling. At the same time, the limiting mechanism further enhances the fixing effect. The cooperation between the plug-in post and the limiting rod ensures a stable connection between adjacent anti-pull components, providing reliable support and protection for the cable.

[0021] Please see Figures 1-4This utility model provides an embodiment of an anti-pull fixing component for an air conditioner inverter cable, including a mounting plate 12. The mounting plate 12 can be welded or fixed to a housing 11 by screws. The housing 11 can be an air conditioner housing 11 or an inverter protection box housing 11, selected according to the actual assembly situation. The housing 11 in the figure is only partially illustrated. The mounting plate 12 is provided with a positioning component, which includes a fixed clamping plate 13 fixedly mounted on the mounting plate 12. The positioning component is also provided with a movable clamping plate 14 by fastening components. Both the fixed clamping plate 13 and the inner arc surface of the fixed clamping plate 13 are provided with rubber pads 15, which can be made of insulating rubber. For the fixed clamping plate 13 and the movable clamping plate 14, such as Figure 2 As shown, an arc-shaped hole is provided to facilitate clamping and fixing the cable head that is plugged into the frequency converter. This provides positioning protection after plugging in, preventing bending or loosening. To avoid affecting plugging in and subsequent unplugging operations, the mounting plate 12 is provided with a fastening component that matches the positioning component. The fastening component includes an adjusting block 32 fixedly installed under the moving clamp plate 14. The mounting plate 12 has an adjusting groove 31 that slides with the adjusting block 32. The adjusting block 32 can be T-shaped, and the adjusting groove 31 is correspondingly provided to guide and limit movement, preventing displacement. The adjusting block 32 is threadedly engaged with a fastening bolt 33. To facilitate positioning and fixing after clamping, the inner wall of the adjusting groove 31 has a threaded hole that engages with the fastening bolt 33, facilitating fastening with the fastening bolt 33. The end of the fastening bolt 33 has an internal hexagonal hole 34 for easy tightening and loosening with tools.

[0022] Please see Figures 1-4To guide and limit the cable, and simultaneously position and fix it to prevent pulling and other situations, thus protecting the cable, anti-pull components are evenly spaced on the housing 11. Adjacent anti-pull components are connected by a limiting mechanism. Two adjacent anti-pull components form a group, and two, three, or four groups can be set according to the actual cable length to ensure effective limiting and fixing. Each anti-pull component includes a fixing seat 21 on the housing 11. The fixing seat 21 has an elastic sheet 22, similar to a leaf spring, providing elasticity for easy cable insertion and subsequent clamping and positioning operations. Symmetrically arranged arc-shaped fixing rings 23 are provided, with anti-slip pads 24 on the inner arc surface of each arc-shaped fixing ring 23 to prevent hard contact with the cable. The limiting mechanism includes... A fixing plate 25 is set at the end of the arc-shaped fixing ring 23 away from the elastic sheet 22. The fixing plate 25 has insertion holes 45. Insertion pins 41 are inserted into the two insertion holes 45 on the same fixing plate 25, which can be used to clamp and fix the cable after placement to avoid slippage. In order to ensure the clamping and fixing effect and prevent the insertion pins 41 from slipping out, and to facilitate subsequent removal operations, the limiting mechanism also includes limiting holes 42 opened on the two adjacent insertion pins 41. A limiting rod 43 is provided in the limiting hole 42. A rubber sleeve 44 is fitted on the outside of the limiting rod 43.

[0023] Working Principle: When using this invention, the cable is placed into the two arc-shaped fixing rings 23 on the fixing base 21. During placement, the arc-shaped fixing rings 23 are spaced apart by the elastic sheet 22 to facilitate cable insertion. After placement, the cable returns to its original position under the action of the elastic sheet 22. The anti-slip pad 24 provides initial clamping and fixation. Then, the cable connector is inserted into the fixed clamping plate 13 and the moving clamping plate 14. After the connector is plugged into the frequency converter, the cable is clamped by pressing the arc-shaped fixing rings 23 on the same fixing base 21. First, fix the connector. Then, insert the plug pin 41 into the plug hole 45 on the fixing plate 25 to complete the initial positioning and fixing. Then, insert the limiting pin into the limiting hole 42 of the two adjacent plug pins 41. With the help of the rubber sleeve 44, the limiting rod 43 can be firmly inserted into the limiting hole 42. Then, push the fixed plate 13, and the adjusting block 32 slides in the adjusting groove 31 and splices with the fixed plate 13 to position and fix the connector. Then, tighten the fastening bolt 33 through the internal hexagonal hole 34 to position and fix the moving plate 14, thus completing the fastening of the connector.
