[0002] A flyback transformer is a special type of transformer mainly used in switching power supplies and cathode ray tube displays, capable of storing and releasing energy on a single magnetic core. Existing flyback transformers energize when the terminal blocks contact the quick-connect terminals, but at this point, the terminal blocks and quick-connect terminals are not fully closed, and some terminals are exposed, posing a risk of electric shock and resulting in poor safety when using the terminals. Utility Model Content

[0003] The purpose of this invention is to provide a quick-connect terminal structure for a flyback transformer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a quick-connect terminal structure for a flyback transformer, including a terminal block and quick-connect terminals. The terminal block includes a housing, on which multiple fixed terminals are fixedly inserted. The housing has multiple through holes, and a movable terminal tube is movably fitted within each through hole. A mounting plate is fixedly connected inside the housing, and the mounting plate has multiple sliding holes corresponding to the movable terminal tube. The movable terminal tube passes through the mounting plate via the sliding holes. A limiting ring plate is fixedly fitted onto the movable terminal tube, and a return spring is fixedly connected between the limiting ring plate and the mounting plate. The quick-connect terminals include a shell snapped onto the outside of the housing, on which multiple terminals corresponding to the movable terminal tube are fixedly inserted. A protective shell is fixedly connected to the shell, and the protective shell has two slots, in which the same protective insert plate is movably inserted. The protective insert plate has multiple insertion holes corresponding to the terminals.

[0006] Furthermore, two elastic locking plates are symmetrically fixedly connected to the outer wall of the shell, and a first triangular locking block is fixedly connected to each of the two elastic locking plates. Two second triangular locking blocks corresponding to the first triangular locking blocks are symmetrically fixedly connected to the outer wall of the shell.

[0007] Furthermore, the protective insert plate is fixedly connected with a buckle groove.

[0008] Furthermore, two fixing plates are symmetrically fixedly connected to the outer wall of the shell, and pin holes are provided on the fixing plates.

[0009] Furthermore, two positioning rails are symmetrically fixedly connected to the outer wall of the housing, and two positioning grooves matching the positioning rails are symmetrically opened on the inner wall of the housing.

[0010] Furthermore, each of the two slots is fixedly connected with a strip-shaped limiting plate, and the protective insert plate is tightly fitted with the strip-shaped limiting plate.

[0011] Furthermore, the positioning rail and the positioning groove are interference-fitted.

[0012] Furthermore, the ends of both the fixed terminal and the connecting terminal near the movable terminal are rounded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, through the design of a housing, fixed terminal block, movable terminal tube, mounting plate, limiting ring plate, return spring, outer shell, terminal block, protective shell, slot, protective insert plate, and socket, allows for the following design: When energized, the movable terminal tube is separated from the fixed terminal block under the action of the return spring. The terminal block is inserted into the terminal block, and as it moves, the terminal block pushes the movable terminal tube. When the terminal block is fully engaged, the movable terminal tube contacts the fixed terminal block, thus connecting the fixed terminal block, movable terminal tube, and terminal block, enabling energization of the terminal. Compared to existing technologies, this terminal block only energizes when fully closed, improving safety. Furthermore, the protective shell and protective insert plate prevent the terminal block from being exposed, further enhancing the safety of the flyback transformer terminal block.

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

[0022] Please see Figure 1-5 This utility model provides a quick-connect terminal structure for a flyback transformer, including a terminal block and quick-connect terminals. The terminal block includes a housing 1, on which multiple fixed terminals 2 are fixedly inserted. The housing 1 has multiple through holes, and a movable terminal tube 3 is movably fitted inside each through hole. A mounting plate 4 is fixedly connected inside the housing 1. The mounting plate 4 has multiple sliding holes corresponding to the movable terminal tube 3. The movable terminal tube 3 passes through the mounting plate 4 through the sliding holes. A limiting ring plate 5 is fixedly fitted on the movable terminal tube 3. A return spring 6 is fixedly connected between the limiting ring plate 5 and the mounting plate 4. The quick-connect terminals include a housing 7 snapped onto the housing 1. Multiple terminals 8 corresponding to the movable terminal tube 3 are fixedly inserted into the housing 7. A protective shell 9 is fixedly connected to the housing 7. The protective shell 9 has two slots 10, and the same protective insert plate 11 is movably inserted into each of the two slots 10. The protective insert plate 11 has multiple insertion holes 12 corresponding to the terminals 8.

[0023] In the above embodiment, when energized, the movable energizing tube 3 and the fixed energizing post 2 are separated under the action of the return spring 6. The energizing terminal is inserted into the terminal block. As the energizing terminal gradually moves, the terminal 8 on the energizing terminal will push the movable energizing tube 3 to move. When the energizing terminal is completely locked on the terminal block, the movable energizing tube 3 contacts the fixed energizing post 2, thereby connecting the fixed energizing post 2, the movable energizing tube 3 and the terminal 8, realizing the energization of the terminal. Compared with the prior art, this terminal will only be energized in the fully closed state, which improves the safety of use. In addition, the protective shell 9 and the protective plug plate 11 can prevent the terminal 8 from being exposed, further improving the safety of the reverse transformer terminal.

[0024] Two elastic locking plates 13 are symmetrically fixedly connected to the outer wall of the housing 7. A first triangular locking block 14 is fixedly connected to each of the two elastic locking plates 13. Two second triangular locking blocks 15 corresponding to the first triangular locking blocks 14 are symmetrically fixedly connected to the outer wall of the housing 1. Through the cooperation of the elastic locking plates 13, the first triangular locking blocks 14 and the second triangular locking blocks 15, quick insertion and quick removal of the terminals can be realized, which improves the convenience of use.

[0025] The protective insert 11 is fixedly connected to a buckle 16, which improves the ease of removing the protective insert 11.

[0026] Two fixing plates 17 are symmetrically fixed to the outer wall of the housing 1. The fixing plates 17 are provided with pin holes 18 to facilitate fixing the terminal block to the flyback transformer.

[0027] Two positioning rails 19 are symmetrically fixedly connected to the outer wall of the housing 1, and two positioning grooves 20 that match the positioning rails 19 are symmetrically opened on the inner wall of the housing 7. The positioning rails 19 and the positioning grooves 20 cooperate with each other to improve the convenience and stability of the connection between the power terminal and the terminal block.

[0028] Both slots 10 are fixedly connected with strip-shaped limiting plates 21. The protective insert plate 11 fits tightly with the strip-shaped limiting plates 21, which can improve the stability of the protective insert plate 11 after it is inserted into the slot 10.

[0029] The positioning rail 19 and the positioning groove 20 are interference-fitted, which improves the stability of the connection between the power terminal and the terminal block.

[0030] The fixed terminal 2 and the terminal 8 are both rounded at the ends near the movable terminal 3, which can improve the tightness of the fit between the fixed terminal 2 and the terminal 8 and the movable terminal 3.

[0031] Working principle: When connected to power, the fixed terminal 2 on the terminal block is connected to the line on the flyback transformer. The terminal is inserted into the terminal block. As the terminal moves, the terminal 8 on the terminal pushes the movable terminal tube 3 to move. When the terminal is fully locked on the terminal block, the movable terminal tube 3 contacts the fixed terminal 2, thereby connecting the fixed terminal 2, the movable terminal tube 3, and the terminal 8, and realizing the power supply of the terminal. Compared with the existing technology, this terminal will only be energized when it is fully closed, which improves the safety of use. In addition, the protective shell 9 and the protective plug plate 11 can prevent the terminal 8 from being exposed, further improving the safety of the flyback transformer terminal.
