Abstract
Description
Technical Field
[0001] The utility model relates to the field of transformers, in particular to an iron core assembly structure. Background Art
[0002] Many existing transformer cores are composed of at least two core blocks that are abutted against each other, and each core block is bundled with a steel belt. The specific assembly method of the core is: first, each core block is abutted against each other and each core block is covered with a steel belt, then the steel belt is tightened by a belt drawing machine and fixed by a steel belt clamp, and finally the gap between the steel belt clamp and the steel belt is soldered. Among them, if the thickness of the adopted steel belt clamp is relatively thin, it is necessary to use pliers to bend the steel belt clamp and then solder it. This has high requirements for the bending. If the bending is improper, the steel belt will become loose or the core block will be damaged. If the thickness of the adopted steel belt clamp is relatively thick, it is necessary to use a hammer to knock the steel belt clamp to fix the steel belt. During operation, in order to avoid damage to the core block due to excessive knocking strength, the knocking strength will be reduced. This will easily lead to insufficient knocking strength and cause the steel belt to loosen, resulting in the inability to tighten the core blocks. As can be seen from the above, the existing core assembly method has the defects of "complex assembly method and inability to tighten the core blocks well".
[0003] In view of the existence of the above problems, it is necessary to study a core assembly structure, which has the advantages of easy assembly and the ability to stably clamp each core block. Utility Model Content

DETAILED DESCRIPTION
[0019] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0020] like Figure 1 and Figure 2 As shown, the utility model discloses an iron core assembly structure, which includes at least two abutting iron core blocks 1 and at least one metal tie 2 for binding each iron core block 1; the metal tie 2 includes a belt body 21 and a self-locking device 22 for locking the belt body 21, the belt body 21 is made of metal, the belt body 21 has a first connecting section 211 and a second connecting section 212, the self-locking device 22 cooperates with the first connecting section 211 of the belt body 21, the second connecting section 212 of the belt body 21 passes through the self-locking device 22 so that the metal tie 2 forms an annular space for sleeve each iron core block 1, and the connection between the second connecting section 212 of the belt body 21 and the self-locking device 22 is welded by solder.
[0021] In the utility model, when assembling an iron core assembly structure of the utility model, each iron core block 1 is firstly abutted against each other and each iron core block 1 is sleeved with a metal tie 2, then the metal tie 2 is tightened by a tie machine, and finally the connection between the second connecting section 212 of the belt body 21 of the metal tie 2 and the self-locking device 22 is welded by solder. Among them, since the metal tie 2 has a self-locking function after being tightened and can stably clamp each iron core block 1, the utility model does not need to use a steel belt clamp, thereby avoiding the defects caused by the use of a steel belt clamp, so that the utility model has the advantages of easy assembly and can stably clamp each iron core block 1; in addition, the connection between the second connecting section 212 of the belt body 21 of the metal tie 2 and the self-locking device 22 is welded by solder, which can further prevent the metal tie 2 from loosening, and further ensure that the utility model can stably clamp each iron core block 1.
[0022] In the embodiment of the present invention, the belt body 21 of the metal cable tie 2 can be made of stainless steel, so that the belt body 21 has high strength and long service life.
[0023] In an embodiment of the utility model, the self-locking device 22 of the metal cable tie 2 includes a through locking sleeve 221 and a locking ball 222 that cooperates with the locking sleeve 221; wherein, the openings at both ends of the locking sleeve 221 are respectively a belt inlet 2211 and a belt outlet 2212, and the inner wall of the locking sleeve 221 is provided with a locking channel 2213 that gradually expands from the belt inlet 2211 to the belt outlet 2212, and the locking ball 222 cooperates in the locking channel 2213; the first connecting section 211 of the belt body 21 is connected to the locking sleeve 221, and the second connecting section 212 of the belt body 21 passes through the belt inlet 2211, the locking channel 2213 and the belt outlet 2212 of the locking sleeve 221 in sequence, and the second connecting section 212 of the belt body 21 is against the locking ball 222, and the second connecting section 212 and the locking ball 222 are clamped in the locking channel 2213. The tightening principle of the metal cable tie 2 of the utility model is as follows: when the second connecting section 212 of the belt body 21 is pulled, the second connecting section 212 of the belt body 21 will drive the locking ball 222 to move toward the belt outlet 2212, and because the locking channel 2213 gradually expands from the belt inlet 2211 to the belt outlet 2212, the locking ball 222 will not clamp the second connecting section 212 of the belt body 21, so that the second connecting section 212 of the belt body 21 can move smoothly; and when the second connecting section 212 of the belt body 21 is pulled until the metal cable tie 2 hugs each iron core block 1 After the position is reached, the force applied to the second connecting section 212 of the belt body 21 is released. Due to the tension of each iron core block 1, the second connecting section 212 of the belt body 21 will move in the opposite direction for a certain distance, so that the second connecting section 212 of the belt body 21 drives the locking ball 222 to move toward the belt inlet 2211. At this time, since the locking channel 2213 gradually expands from the belt inlet 2211 to the belt outlet 2212, the second connecting section 212 of the belt body 21 and the locking ball 222 will be clamped in the locking channel 2213, thereby making the metal cable tie 2 self-locking.
[0024] In the embodiment of the utility model, the locking sleeve 221 and the locking ball 222 of the self-locking device 22 can be made of metal, so that the locking sleeve 221 and the locking ball 222 of the self-locking device 22 have high strength and long service life, thereby making the metal cable tie 2 more stable when self-locking. Specifically, the locking sleeve 221 and the locking ball 222 of the self-locking device 22 can be made of stainless steel.
[0025] In an embodiment of the utility model, the outlet 2212 of the lock sleeve 221 is provided with a stopper 2214 for abutting against the lock ball 222, thereby preventing the stopper 2214 from falling out of the lock sleeve 221; the stopper 2214 can be an elastic structure, so that the lock ball 222 can be directly installed into the lock sleeve 221 by hard embedding, and the method of installing the lock ball 222 is very simple.
[0026] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
