Description

Technical Field

[0001] This utility model relates to the field of flash lamp transformer technology, specifically a transformer coil frame for flash lamps. Background Technology

[0002] A flash transformer is a high-voltage trigger transformer used in camera or mobile phone flash circuits. It features a long magnetic circuit, low magnetic reluctance, high magnetic flux, and low magnetic leakage, resulting in minimal electromagnetic interference to surrounding circuits. This makes it ideal for digital cameras and mobile phones with sophisticated circuitry. In flash circuits, the transformer plays a crucial role in voltage conversion and trigger control. Modern compact flash units often employ high-frequency oscillation circuits in conjunction with transformers, using rapid switching control to achieve efficient voltage boosting, replacing the bulky power supply box structure of earlier models. While silver / nickel-cadmium batteries directly powering compact electronic flash units are gradually replacing external power supply boxes, the core boost transformer remains irreplaceable; its miniaturization and high-efficiency design are key technological advancements.

[0003] Most flash unit transformer frames on the market are currently made in one piece, and are quite large in size. When a component of the transformer fails, the entire transformer needs to be replaced, resulting in high replacement costs. Although there are also split transformer frames on the market, in order to ensure the stability of the transformer structure, the parts of the existing split transformer frames need to be fixed together, and some are even fixed with glue, which makes disassembly and assembly inconvenient and hinders future maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a transformer coil frame for flash lamps. By designing the frame body and the outer shell as a separate structure, it is easy to disassemble and assemble. When replacing or repairing, it is not necessary to replace the entire transformer frame, thereby reducing the replacement cost. This solves the problem mentioned in the background art that the existing flash lamp transformer frames are inconvenient to disassemble and assemble, and not conducive to later maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A transformer coil frame for a flash lamp adopts a split structure, including a frame body and a shell that can be detachably installed on the frame body. The frame body is I-shaped and includes two support blocks arranged opposite each other and a core cylinder connected to the two support blocks. Each support block has a first slot on its bottom wall and a second slot on its top wall. The bottom end of the shell is embedded in the first slot and the top end of the shell is snapped into the second slot.

[0007] Preferably, the outer shell includes a cover plate and side plates that are vertically connected to the two edges of the cover plate. The length of the cover plate is longer than the length of the side plates. The two ends of the cover plate are respectively horizontally embedded in the first slots of the support blocks, and the side plates are embedded between the two support blocks.

[0008] Preferably, the bottom wall of the cover plate is flush with the bottom wall of the support block, and the side wall of the side plate is flush with the side wall of the support block.

[0009] Preferably, the top of each side plate protrudes outward to form a buckle portion that is embedded in the second slot.

[0010] Preferably, the second slot is located at the top two corners of the opposite surfaces of the two support blocks, and there are a total of four second slots, which are symmetrically located on the end walls of the support blocks.

[0011] Preferably, one of the support blocks has a first insertion hole extending downward to the first slot on its top surface, a first pin inserted into the first insertion hole, and the top end of the first pin bent toward the center of the top surface of the support block to form a horizontal first flat foot; the other support block has a second insertion hole extending downward to the first slot on its top surface, a second pin inserted into the second insertion hole, and the top end of the second pin bent toward the center of the top surface of the support block to form a horizontal second flat foot.

[0012] Preferably, the bottom end of the first pin extends downward to the outside of the first slot to form a first stand, and the bottom end of the second pin extends downward to the outside of the first slot to form a second stand.

[0013] Preferably, a receiving groove is formed between the inner wall of the outer shell and the inner walls of the two support blocks and the outer peripheral wall of the core cylinder.

[0014] Preferably, the first slot has a wire groove that communicates with the receiving slot.

[0015] Preferably, the sidewall of the support block has a central hole that extends through both sides and communicates with the core cylinder.

[0016] Compared with the prior art, the advantages of this utility model are: by designing the frame body and the outer shell as a separate structure, it is easy to disassemble and assemble; during assembly, it is only necessary to first snap the bottom end of the outer shell into the first slot of the support block, and then snap the top end of the outer shell into the second slot of the support block; when it is necessary to remove the outer shell from the frame body for replacement or repair, it is only necessary to pry out the top and bottom ends of the outer shell in reverse order of assembly, which is simple and convenient to operate, without the need to replace the entire transformer frame, thereby reducing replacement costs.

[0025] Please see Figure 1-3 A transformer coil frame for a flash unit is disclosed, employing a split structure. It includes a frame body 1 and a housing 2 detachably mounted on the frame body 1. The frame body 1 is I-shaped and includes two opposing support blocks 11 and a core cylinder 12 connected to the two support blocks 11. Each support block 11 has a first slot 111 on its bottom wall and a second slot 112 on its top wall. The bottom end of the housing 2 is embedded in the first slot 111, and the top end of the housing 2 is snapped into the second slot 112.

[0026] Please see Figure 4-5 In this embodiment, the support block 11 has a central hole 113 that runs through both sides and communicates with the core cylinder 12 on its side wall. The central hole 113 is used to insert the magnetic core.

[0027] By designing the frame body 1 and the outer shell 2 as a separate structure, it is easy to disassemble and assemble. During assembly, simply insert the bottom end of the outer shell 2 into the first slot 111 of the support block 11, and then insert the top end of the outer shell 2 into the second slot 112 of the support block 11. When the outer shell 2 needs to be removed from the frame body 1 for replacement or repair, simply pry out the top and bottom ends of the outer shell 2 in the reverse order of assembly. The operation is simple and convenient, and there is no need to replace the entire transformer frame, thereby reducing replacement costs.

[0028] Please see Figure 3 and Figure 5The bottom wall of the outer shell 2 is flush with the bottom walls of the two support blocks 11, so that the bottom walls of the outer shell 2 and the support blocks 11 form a standard horizontal plane, which makes it convenient for the pick-and-place machine's nozzle to pick up and perform surface mounting, which is beneficial to product processing.

[0029] Please see Figure 1 An accommodating groove 3 is formed between the inner wall of the outer shell 2 and the inner walls of the two support blocks 11 and the outer peripheral wall of the core cylinder 12. The accommodating groove 3 is used to accommodate the winding coil, and the outer shell 2 plays the role of protecting the winding coil.

[0030] Please see Figure 1 and 2 The outer casing 2 includes a cover plate 21 and side plates 22 perpendicularly connected to the two edges of the cover plate 21. The length of the cover plate 21 is longer than the length of the side plates 22. Both ends of the cover plate 21 are horizontally embedded in the first slots 111 of the support blocks 11. The bottom wall of the cover plate 21 is flush with the bottom wall of the support blocks 11. The side plates 22 are embedded between the two support blocks 11, and the side walls of the side plates 22 are flush with the side walls of the support blocks 11, facilitating product mounting. Furthermore, because the cover plate 21 and the side plates 22 are embedded within the walls of the support blocks 11, the overall product volume is reduced, making it easier to clamp inside a flash unit.

[0031] The top of the side plate 22 protrudes outward to form a latching part 221 embedded in the second latching groove 112. In this embodiment, the second latching groove 112 is provided at the top two corners of the opposite surfaces of the two support blocks 11, and there are a total of four second latching grooves 112, which are symmetrically arranged on the end walls of the support blocks 11.

[0032] By embedding the cover plate 21 into the first slot 111 and simultaneously embedding the two side plates 22 into the symmetrical second slots 112, the connection between the outer shell 2 and the support block 11 is made more stable. The two side plates 22 have a certain degree of elasticity. During assembly, the two side plates 22 open outward relative to the cover plate 21. After the cover plate 21 is embedded into the first slot 111 from below the support block 11, the two side plates 22 close towards the middle until the latching part 221 of the side plate 22 is engaged in the second slot 112 of the support block 11. When it is necessary to remove the outer shell 2 from the support block 11, simply open the side plate 22 outward to disengage the latching part 221 from the second slot 112, and the entire outer shell 2 can be removed from below the support block 11.

[0033] Please see Figure 2One of the support blocks 11 has a first insertion hole 114 extending downward to the first slot 111 on its top surface. A first pin 4 is inserted into the first insertion hole 114, and the tip of the first pin 4 is bent towards the center of the top surface of the support block 11 to form a horizontal first flat foot 41. The other support block 11 has a second insertion hole 115 extending downward to the first slot 111 on its top surface. A second pin 5 is inserted into the second insertion hole 115, and the tip of the second pin 5 is bent towards the center of the top surface of the support block 11 to form a horizontal second flat foot 51. In this embodiment, the length of the first flat foot 41 is longer than the length of the second flat foot 51.

[0034] Please refer to Figure 2 The second socket 115 and the second pin 5 are both two in number, and the second flat feet 51 of the two second pins 5 are symmetrically arranged; the bottom end of the first pin 4 extends downward to the outside of the first slot 111 to form the first upright foot 42. The bottom end of the second pin 5 extends downward to the outside of the first slot 111 to form the second upright foot 52. The first upright foot 42 and the second upright foot 52 are used for winding wire; the first flat foot 41 and the second flat foot 51 are used for surface mount soldering.

[0035] Please see Figure 3 The first slot 111 has a wire groove 116 that communicates with the receiving slot 3. The wire groove 116 is used to lead out the wire in the receiving slot 3. In the embodiment, the first foot 42 and the second foot 52 both pass through the wire groove 116. The wire led out from the wire groove 116 is used to wrap around the first foot 42 and the second foot 52.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
