Description

Technical Field

[0001] This utility model relates to the field of inverter wiring harness application technology, and in particular to an inverter connection wiring harness with an anti-loosening structure. Background Technology

[0002] An inverter is a converter that transforms direct current (DC) power into alternating current (AC) power of fixed frequency and voltage or variable frequency and voltage. It is widely used in air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, televisions, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, and other fields. During the use of an inverter, wiring harnesses are required to connect the various components.

[0003] However, existing inverter connection harnesses are prone to loosening between the connection terminals and the mating plugs under prolonged use or exposure to external forces such as vibration and impact. This can lead to circuit interruptions, affecting the normal operation of the inverter and potentially causing safety accidents. Therefore, an inverter connection harness with an anti-loosening structure is needed to improve the stability and safety of the connection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an inverter connection harness with an anti-loosening structure, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an inverter connection harness with an anti-loosening structure, including multiple connection wires, the two ends of the multiple connection wires being electrically connected to connection terminals to realize the insertion and fixing of the connection wires;

[0006] Both of the connecting terminals are fitted with snap-fit ​​structures on the outside to secure and fix the connected terminals after insertion.

[0007] The present invention is further configured such that: one end of the connecting terminal is fixedly connected to a push plate, and the other end is provided with multiple insertion holes.

[0008] The above technical solution facilitates the use of a push plate to move the entire connection terminal, thereby allowing it to be inserted into the mating plug through multiple insertion holes to form a circuit connection.

[0009] The present invention is further configured such that: the connecting terminal is arranged in a trapezoidal shape, and a positioning groove is provided on the connecting terminal near the push plate.

[0010] The above technical solution facilitates the quick installation of the card holder using the positioning slot, making it easier to replace the snap-fit ​​structure and reducing the replacement cost of the entire connection terminal.

[0011] The present invention is further configured such that: the buckle structure includes a card holder that engages with the positioning groove, both ends of the card holder are fixedly connected to a pressing part, the pressing part is fixedly connected to an embedding block, the end face of the embedding block is fixedly connected to an engaging part, and a spring piece is embedded in the card holder near the end face, and the spring piece is movably connected to the embedding block.

[0012] Through the above technical solution, the connecting terminal drives the insert blocks on both sides of the card holder to be inserted into the inside of the mating plug. The inner wall of the plug squeezes the engaging part, causing the insert block to be squeezed against the spring piece. This allows the insert block to carry the engaging part into the limiting protrusion inside the mating plug. When engaging, the pressure is released, allowing the spring piece to drive the engaging part on the insert block to be stably engaged and connected to the inner wall of the mating plug, thereby positioning and fixing the connecting terminal. When disassembling it, simply press the pressing part to move the engaging part on the insert block away from the matching slot inside the mating plug to disassemble the connecting terminal.

[0013] The present invention is further configured such that the pressing part is curved in an arc shape and the bottom is inclined toward the embedded block.

[0014] The above technical solution facilitates the application of pressure by workers in the disassembly direction, improving comfort during the disassembly process.

[0015] The present invention is further configured such that: one end of the spring is embedded in a slot opened near the end face of the card holder, and the other end is fitted and connected to the inside of a movable groove opened on the side wall of the embedded block.

[0016] The above technical solution facilitates the locking and fixing of the spring piece, and allows for limited sliding adjustment within the movable groove when pressure is applied.

[0017] The present invention is further configured such that the portion of the spring piece away from the card holder is arc-shaped, and the bending direction is toward the embedding block.

[0018] The above technical solution facilitates elastic deformation of the curved part within a certain space, making it convenient for compression and repositioning activities.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The inverter connection harness with anti-loosening structure proposed in this utility model has a reinforcing spring between the embedded block and the card holder. When the embedded block is inserted into the docking plug along with the connection terminal, the elasticity of the spring can be used to stably lock the embedded block into the docking plug, thereby improving the firmness during operation.

[0021] 2. The inverter connection harness with anti-loosening structure proposed in this utility model has a curved pressing part on the embedded block, so that the operator can quickly press and disassemble when disassembling the connection terminal, and use a bracket for connection and fixation, which facilitates the replacement of the operator after the bracket is damaged and reduces the replacement cost of the connection terminal.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2As shown, an inverter connection harness with an anti-loosening structure includes multiple connecting wires 1. Both ends of the multiple connecting wires 1 are electrically connected to connecting terminals 2 to realize the insertion and fixation of the connecting wires 1. The connecting terminals 2 are arranged in a trapezoidal shape. The connecting terminals 2 have a positioning groove 22 near the push plate 21, which facilitates the quick installation of the clip 31 by using the positioning groove 22, so as to facilitate the replacement of the clip structure 3 and reduce the replacement cost of the entire connecting terminal 2. One end of the connecting terminal 2 is fixedly connected to the push plate 21, and the other end has multiple insertion holes 23, which facilitates the use of the push plate 21 to drive the entire connecting terminal 2 to move, so as to insert into the mating plug to form a circuit connection by using the multiple insertion holes 23.

[0030] like Figures 3-5 As shown, both connecting terminals 2 are fitted with snap-fit ​​structures 3 to secure the connected terminals 2 after insertion. The snap-fit ​​structure 3 includes a card holder 31 that engages with the positioning groove 22. Both ends of the card holder 31 are fixedly connected with pressing parts 32. The pressing parts 32 are curved and inclined towards the insert block 33 at the bottom, which facilitates the worker to apply pressure in the disassembly direction and improves comfort during disassembly. The pressing parts 32 are fixedly connected to the insert block 33. The end face of the insert block 33 is fixedly connected with a snap-fit ​​part 34. A spring piece 35 is embedded near the end face of the card holder 31. The part of the spring piece 35 away from the card holder 31 is curved and the bending direction is towards the insert block 33, which facilitates elastic deformation in a certain space using the curved part, making it convenient for squeezing and resetting. One end of the spring piece 35 is embedded in the slot 311 opened near the end face of the card holder 31, and the other end is attached to the insert block 34. The movable groove 331 on the side wall facilitates the locking and fixing of the spring piece 35. When pressure is applied, it can slide and adjust within a limited range inside the movable groove 331. The spring piece 35 is movably connected to the insert block 33. The insert blocks 33 on both sides of the card holder 31 are inserted into the docking plug by the connection terminal 2. The inner wall of the plug presses against the locking part 34, causing the insert block 33 to press against the spring piece 35. This allows the insert block 33 to carry the locking part 34 into the limiting protrusion inside the docking plug. When locking, the pressure is released, allowing the spring piece 35 to drive the locking part 34 on the insert block 33 to stably lock and connect to the inner wall of the docking plug, thereby positioning and fixing the connection terminal 2. When disassembling, simply press the pressing part 32 to move the locking part 34 on the insert block 33 away from the matching slot inside the docking plug to disassemble the connection terminal 2.

[0031] In use, the buckle structure 3 is first fitted into the positioning groove 22 via the clip 31. Then, the connecting terminal 2 is inserted into the mating plug using the push plate 21, which causes the inserting blocks 33 on both sides of the clip 31 to be inserted into the mating plug. The inner wall of the plug presses against the engaging part 34, causing the inserting block 33 to be pressed against the spring piece 35. This allows the inserting block 33 to carry the engaging part 34 into the limiting protrusion inside the mating plug. When engaging, the pressure is released, causing the spring piece 35 to drive the engaging part 34 on the inserting block 33 to be stably engaged and connected to the inner wall of the mating plug, thereby positioning and fixing the connecting terminal 2. When disassembling, simply press the pressing part 32 to move the engaging part 34 on the inserting block 33 away from the matching slot inside the mating plug, and the connecting terminal 2 can be disassembled.
