Abstract
Description
Technical Field
[0001] The utility model relates to the field of small transformer structures, in particular to a transformer which is easy to absorb. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage regulation (magnetic saturation transformer). Small transformers, due to their small size, cannot be handled with grippers during automated production. Most transformers have through-holes running horizontally through the core, with the coils positioned within them. This means the top surface of the core has a large flat surface, which satisfies the gripping requirements of suction cups. Therefore, suction cups are generally used to transport transformers. However, for some transformers, the through-holes on the core are vertically arranged, meaning there is no large flat surface on the top of the core, making it difficult for suction cups to grip. To enable automated product transportation, it is necessary to develop a transformer that is easily retractable to address these issues. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings:
[0016] like Figure 1 As shown, it is a traditional transformer structure, the holes on the core 13 are arranged horizontally, so the upper end surface of the core 13 is a complete plane, which is convenient for the suction cup to grab. Figure 3 As shown), the top of the iron core 13 is not a complete plane, and the area available for the suction cup to absorb is limited.
[0017] like Figures 2 to 4As shown, a transformer that is easy to absorb includes a transformer body 1 and an auxiliary top cover 2. The transformer body 1 includes a plastic bracket 11, pins 12, an iron core 13 and a coil 14. The pins 12 are provided in multiple groups and are respectively fixed on the front and rear sides of the plastic bracket 11. The iron core 13 is fixed above the plastic bracket 11. The outer sides of the iron core 13 are all vertical planes. The middle part of the iron core 13 is provided with a through hole 131 that vertically penetrates the iron core 13. The coil 14 surrounds the middle part of the plastic bracket 11 and is connected to all the pins 12. The coil 14 corresponds to the through hole 131. The auxiliary top cover 2 is made of metal material. The auxiliary top cover 2 includes an integrally arranged top cover plate 21, a pressing plate 22, a guide plate 23 and a limit plate 24. The top cover plate 21 corresponds to the top of the iron core 13 and contacts the plane around the iron core 13. The upper surface of the top cover plate 21 is a plane. The clamping plate 22 is an arc-shaped plate protruding outward. The upper end of the clamping plate 22 is connected to the edge of the top cover plate 21, and the lower end of the clamping plate 22 touches the side wall of the iron core 13. The upper end of the guide plate 23 is connected to the lower end of the clamping plate 22, and the lower end of the guide plate 23 is bent outward. The clamping plate 22 and the guide plate 23 are each provided with two groups and correspond to the front and rear sides of the transformer body 1. The limit plate 24 corresponds to the outer wall of the iron core 13. The upper end of the limit plate 24 is connected to the edge of the top cover plate 21. The limit plate 24 is provided with two groups and corresponds to the left and right sides of the transformer body 1 respectively.
[0018] By putting the auxiliary top cover 2 on the transformer body 1, a flat surface for suction cups to absorb can be provided for the top of the transformer body 1. When the auxiliary top cover 2 is put down on the transformer body 1, the guide plate 23 first contacts the top of the iron core 13 and pushes the clamping plate 22 outward, and then continues to be inserted downward so that the top cover 21 contacts the top of the iron core 13. At this time, the clamping plates 22 on the front and back sides clamp the iron core 13, thereby fixing the top cover 21. The limit plates 24 correspond to the left and right sides of the iron core 13 to prevent the top cover 21 from being displaced to the left and right, thereby improving the accuracy of subsequent transformer grasping and processing. The advantage of this design is that it can provide a flat surface for suction cups to absorb for the top of the transformer body 1, which is suitable for automated production. After automated production, the auxiliary top cover 2 can be removed or retained according to product requirements, and the removed auxiliary cover can be recycled.
[0019] The auxiliary top cover 2 is made of aluminum plate or stainless steel plate. When aluminum plate is used, its elasticity is better, which facilitates the insertion and removal of the auxiliary top cover 2. When stainless steel plate is used, its strength is higher and the shape is more stable, which is conducive to improving the accuracy of subsequent processing.
[0020] There is a gap 221 between the inner side of the pressing plate 22 and the iron core 13 . Grooves 132 are provided on both the front and rear sides of the upper end of the iron core 13 . The outer sides of the grooves 132 are connected to the gap 221 .
[0021] The groove 132 can prevent vacuum from forming between the top cover plate 21 and the upper end surface of the core 13, making it easier to pull out the top cover plate 21. After the top cover plate 21 is pulled out, the groove 132 can also be used as a positioning groove in other processes.
[0022] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
