Description

Technical Field

[0001] This utility model relates to the field of onboard reactor technology, specifically to an onboard reactor without a PIN pin skeleton. Background Technology

[0002] In the field of electronic equipment, the performance and cost of reactors are crucial to the overall efficiency and production cost of the equipment. Traditional onboard reactors mostly adopt a pin-based frame structure, which requires the copper wire to be bonded to the frame pins and then tinned during production. However, this process has obvious drawbacks: the copper wire and pins are prone to poor soldering and missing solder joints, affecting the reactor performance and causing equipment failure; at the same time, the large amount of solder bars and flux used increases costs and is also environmentally unfriendly.

[0003] To address the aforementioned issues, the industry has introduced onboard reactors with pinless bobbins. The pinless bobbin is wound using automated winding equipment to create the coil, which is then tinned using an automated tinning machine. After being fitted with silicon steel sheets, it is laser-welded to form a semi-finished product. A specialized shaping machine then shapes and trims the copper leads, and finally, it is fixed with epoxy adhesive. This successfully replaces bobbins containing pins, eliminating the risk of cold solder joints and missed solder joints, reducing the amount of solder bars and flux used, and achieving cost savings and energy reduction.

[0004] However, this type of reactor also presents new problems in practical applications. Once the copper wire is fixed with epoxy adhesive, it is very difficult and laborious to remove or replace it if repair or replacement is required later due to its strong adhesion. Utility Model Content

[0005] To solve the above technical problems, an onboard reactor without a pin-pin skeleton is provided. This solves the problem that if copper wires are fixed with epoxy adhesive, it is very difficult and laborious to remove or replace them later due to their strong adhesion.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a board-mounted reactor without a pin-shaped skeleton, comprising a pinless skeleton and copper wire wound on the pinless skeleton, the two ends of the copper wire respectively passing through the two sides of the top of the pinless skeleton, and assembly grooves are provided on both sides of the top of the pinless skeleton. A quick separation part is built into the copper wire, and a compression limiting part that cooperates with the quick separation part is also provided on the outside of the assembly groove.

[0007] Preferably, the quick separation part includes a movable seat that slides within the assembly groove via a slider and a groove, the end of the copper wire passing through the movable seat and being fixedly connected to the movable seat by epoxy adhesive.

[0008] Preferably, the compression limiting part includes a pressure plate detachably attached to the side of the needleless skeleton and a pressure block vertically fixed to one side of the pressure plate, the end of the pressure block abutting against the movable seat.

[0009] Preferably, both ends of the pressure plate are fixedly penetrated by positioning sleeves, and the side of the needleless skeleton is provided with positioning holes that are compatible with the positioning sleeves.

[0010] Preferably, a positioning stud is threaded through the inner side of the positioning sleeve, and a threaded hole adapted to the positioning stud is provided on the innermost inner wall of the positioning hole.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] (1) By setting up a quick separation part, the lead-out part of the copper wire is directly fixed to the movable seat by epoxy glue. Then, by utilizing the sliding property of the movable seat inside the assembly slot, it is only necessary to easily remove the movable seat from the inside of the assembly slot later to quickly disconnect the copper wire from the needleless skeleton, which makes it convenient for manual replacement of the copper wire from the needleless skeleton in a short time.

[0013] (2) By setting the compression limiting part, the movable seat is slidably inserted into the inner side of the assembly groove, and then the pressure plate is assembled on the side of the needleless skeleton so that the pressure block abuts against the movable seat. In this way, the movable seat can be effectively limited to prevent the movable seat from sliding sideways during the normal use of the needleless skeleton, which would affect the stability of the copper wire lead-out part.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figure 1-3 As shown, an onboard reactor without pins includes a pinless frame 1 and copper wires 2 wound on the pinless frame 1, with the two ends of the copper wires 2 passing through the two sides of the top of the pinless frame 1 respectively.

[0021] An automated multi-axis / single-axis winding machine is used to wind copper wire 2 onto the pinless frame 1. Then, both ends of the copper wire 2 are sequentially passed through the top sides of the pinless frame 1. After both ends of the copper wire 2 are passed through, an automatic tinning machine is used for tinning. Next, a specialized pin shaping machine is used to shape and cut the copper wire 2 to a specific size. Finally, epoxy adhesive is used for fixation. Through this series of operations, the pin-containing frame can be replaced, thereby eliminating the PIN pins of the onboard reactor frame and eliminating the subsequent tinning process for bonding the copper wire to the PIN pins. This not only eliminates the risk of poor soldering or missing solder joints between the copper wire and PIN pins but also reduces the amount of solder bars and flux used, ultimately achieving the goal of cost reduction and energy saving.

[0022] However, after the lead-out part of the copper wire 2 is fixed with epoxy adhesive, the firmness between the lead-out part of the copper wire 2 and the needleless skeleton 1 can be guaranteed to a certain extent. However, if it needs to be repaired or replaced later, it will be very difficult and laborious to remove and replace the copper wire due to its strong adhesiveness.

[0023] Thus, referring to Figure 2 and Figure 3 As shown, it is worth noting that both sides of the top of the needleless skeleton 1 are provided with assembly slots 5, and the copper wire 2 has a built-in quick separation part.

[0024] The quick separation part includes a movable seat 4 that slides in the inner side of the assembly groove 5 via a slider and a groove. The end of the copper wire 2 passes through the movable seat 4 and is fixedly connected to the movable seat 4 by epoxy glue 3.

[0025] By setting up a quick separation section, the lead-out part of the copper wire 2 is directly fixed to the movable seat 4 by the epoxy glue 3. Then, by utilizing the sliding property of the movable seat 4 inside the assembly groove 5, the connection between the copper wire 2 and the needleless frame 1 can be quickly disconnected by simply removing the movable seat 4 from the inside of the assembly groove 5. This makes it convenient for manual replacement of the copper wire 2 from the needleless frame 1 in a short time.

[0026] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that the outer side of the assembly groove 5 is also provided with a compression limiting part that cooperates with the quick separation part;

[0027] The compression limiting part includes a pressure plate 6 detachable from the side of the needleless skeleton 1 and a pressure block 7 vertically fixed to one side of the pressure plate 6. The end of the pressure block 7 abuts against the movable seat 4.

[0028] By setting the compression limiting part, the movable seat 4 is slidably inserted into the inner side of the assembly groove 5. Then, the pressure plate 6 is assembled on the side of the needleless frame 1 so that the pressure block 7 abuts against the movable seat 4. In this way, the movable seat 4 can be effectively limited to prevent it from sliding sideways during normal use of the needleless frame 1, which would affect the stability of the copper wire 2 lead-out part.

[0029] Furthermore, referring to Figure 3 As shown, it is worth noting that both ends of the pressure plate 6 are fixedly penetrated by positioning sleeves 8, and the side of the needleless skeleton 1 is provided with positioning holes 9 that are compatible with the positioning sleeves 8.

[0030] When the pressure plate 6 is attached to the side of the needleless skeleton 1, it is important to align the positioning sleeve 8 with the inside of the positioning hole 9. In this way, the positioning hole 9 and the positioning sleeve 8 can make the pressure plate 6 fit smoothly against the needleless skeleton 1, ensuring the pressure effect of the pressure block 7 on the movable seat 4.

[0031] Furthermore, referring to Figure 3 As shown, it is worth noting that the positioning sleeve 8 has a positioning stud 10 threaded through its inner side, and the innermost inner wall of the positioning hole 9 has a threaded hole that matches the positioning stud 10.

[0032] After the pressure plate 6 is smoothly attached to the side of the needleless skeleton 1, the positioning stud 10 is then turned so that the positioning stud 10 passes into the threaded hole under the thread structure, which can effectively fix the pressure plate 6 and the pressure block 7 as a whole, so that the pressure block 7 stably presses against the movable seat 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
