Description

Technical Field

[0001] The utility model relates to the technical field of transformer assembly, in particular to a combined transformer frame. Background Art

[0002] An electronic transformer is an electronic device that converts the alternating voltage of the mains into direct current and then outputs a high-frequency alternating voltage through semiconductor switching devices, electronic components and high-frequency transformer windings. It is also an AC-DC-AC inverter circuit described in electronics theory. In simple terms, it is mainly composed of a high-frequency transformer core (iron core) and two or more coils, which do not change their positions. From one or more electrical circuits, AC power is converted into AC voltage and current through electromagnetic induction. At the output end of the high-frequency transformer, high-frequency AC or DC power of different voltage levels is supplied to one or more power circuits.

[0003] The electronic transformer is mainly composed of a skeleton, wires, magnetic cores, copper foil, etc. During assembly, the wires are first wound around the outside of the skeleton to form a coil, and then two matching magnetic cores are plugged into the two ends of the skeleton to surround the coil. After the plugging is completed, adhesives are used to pre-position the two magnetic cores at the joints, and then the magnetic cores are wrapped and fixed with insulating tape.

[0004] The above structure uses bonding to pre-position the core contacts at both ends, which is cumbersome to operate. When disassembling, the adhesive needs to be heated and melted with a hot air gun before disassembly, which reduces the installation or disassembly efficiency of the device. Utility Model Content

[0005] The technical problem to be solved by the utility model is that it is not possible to conveniently and quickly perform pre-positioning operation on the contact point of the end of the magnetic core, resulting in a reduction in the efficiency of installation or disassembly.

[0006] In order to solve the above problems, the technical solution of the utility model is: a combined transformer skeleton, including a skeleton body, a coil is wound on the skeleton body, a slot is opened in the skeleton body and magnetic cores are inserted at both ends of the slot for mutual use;

[0007] An upper extension seat and a lower extension seat are respectively provided at the upper and lower ends of the left and right ends of the skeleton body. A plurality of abutment springs are fixedly provided on the relative end faces of the upper extension seat and the lower extension seat at equal intervals along their width direction. An abutment seat is commonly fixed on the plurality of abutment springs on the same end face, and matching matching seats are respectively fixedly provided on the magnetic cores corresponding to the abutment seats.

[0008] Furthermore, the opposing end surfaces of the abutting seat and the matching seat are respectively provided with wedge-shaped surface structures for use in cooperation with each other.

[0009] Furthermore, each of the abutment seats is provided with a plurality of weight-reducing grooves equidistantly arranged along the width direction thereof.

[0010] Furthermore, reinforcing ribs are fixedly provided between the front and rear ends of the upper extension seat and the lower extension seat and the end surface of the frame body.

[0011] Furthermore, the upper extension seat and the lower extension seat are respectively formed integrally with the skeleton body.

[0012] The advantages of the utility model compared with the existing technology are:

[0013] 1. Through the cooperation of the upper extension seat and the lower extension seat, and under the action of the abutting spring, the abutting seat and the matching seat, when the magnetic cores at both ends are inserted into the frame body, under the reaction force of the abutting spring, the abutting seat can be closely abutted against the end surface of the matching seat, and an effective pre-positioning operation can be performed on it, so that the magnetic core can be conveniently and quickly installed or removed, thereby improving the practicality of the device;

[0014] 2. The provided reinforcing ribs can ensure the stability of the upper extension seat and the lower extension seat during use, thereby improving the use efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 3As shown, a combined transformer skeleton comprises a skeleton body 1, a coil 2 is wound on the skeleton body 1, a slot 3 is opened in the skeleton body 1 and magnetic cores 8 are inserted at both ends of the slot 3 for mutual use, and the above features belong to the prior art;

[0021] An upper extension seat 4 and a lower extension seat 5 are symmetrically provided at the upper and lower ends of the left and right ends of the skeleton body 1, and a plurality of abutment springs 6 are fixedly provided on the opposite end faces of the upper extension seat 4 and the lower extension seat 5 at equal intervals along their width direction, and an abutment seat 7 is fixedly provided on the plurality of abutment springs 6 on the same end face, and matching matching seats 9 are fixedly provided on the magnetic cores 8 corresponding to the abutment seats 7.

[0022] Through the above structure, when the magnetic cores 8 at both ends are inserted into the skeleton body 1, under the reaction force of the abutment spring 6, the abutment seat 7 is tightly abutted against the end face of the matching seat 9, and the magnetic cores 8 at both ends can be pre-positioned conveniently and quickly, thereby improving the installation or disassembly efficiency of the device.

[0023] The opposing end surfaces of the abutting seat 7 and the matching seat 9 are respectively provided with wedge-shaped surface structures for use with each other. The wedge-shaped surface structures can increase the stability of the matching seat 9 and the abutting seat 7 during the matching process.

[0024] Each of the abutment seats 7 is also provided with a plurality of weight-reducing grooves 10 equidistantly arranged along the width direction thereof. The weight-reducing grooves 10 can reduce the bearing force on the abutment spring 6 when the mating seat 9 and the abutment seat 7 are not connected.

[0025] Reinforcing ribs 11 are fixed between the front and rear ends of the upper extension seat 4 and the lower extension seat 5 and the end surface of the skeleton body 1 , and the arrangement of the reinforcing ribs 11 can ensure the stability of the upper extension seat 4 and the lower extension seat 5 during use.

[0026] The upper extension seat 4 and the lower extension seat 5 are respectively formed integrally with the frame body 1 .

[0027] In specific use, the coil 2 is first wound around the outer surface of the skeleton body 1, and then the magnetic cores 8 at both ends are inserted into the two ends of the skeleton body 1 and surround the coil 2. During the insertion of the magnetic core 8, the abutment seats 7 at the upper and lower ends are pushed to move away from each other through the matching seats 9 at the upper and lower ends, and at the same time, the abutment spring 6 is driven to contract. After the installation is completed, under the reaction force of the abutment spring 6, the abutment seat 7 is tightly abutted against the matching seat 9, and the magnetic core 8 is effectively pre-positioned. Finally, the insulating tape is wrapped around the outer surface of the magnetic core 8, and the magnetic core 8 is installed conveniently and quickly, thereby improving the practicality of the device.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
