Abstract
The utility model relates to the technical field of electronic equipment, in particular to a transformer framework which is easily to be fixed and has stable structure, and is realized through the technical proposal that the lower end of the framework is fixedly connected with a connecting seat which is provided with a through hole used for the connecting bolts, and the framework consists of a left framework and a right framework which are symmetrical and connected through embedded structure that a binding end surface of the left framework and the right framework is provided with corresponding convex tongues and grooves. After adopting the structure, firstly, the connecting seat which is fixedly connected with the lower end of the framework is provided with the through hole used for connecting the bolts, so only the bolts are needed to fix the connecting seat to a substrate when fixing the framework, and secondly, the binding end surface of the left framework and the right framework is provided with the corresponding convex tongues and grooves, so when in assembly, the location of the left framework and the right framework can be realized directly through the embedment of the convex tongues and grooves, thus having simple and convenient operation.
Description
Technical field:
The utility model relates to technical field of electronic equipment, and refer in particular to a kind of being convenient to and fix, and the skeleton of the firm transformer of structure.
Background technology:
Small-sized transformer is seen everywhere in life, it can be converted to normally used interchange, high pressure civil power the direct current of the needed low-voltage of people, this direct current is used to provide to some low power equipment and uses, such as just being provided with a transformer in the frequent charger for mobile phone that uses of people.Transformer mainly is made up of skeleton, silicon steel sheet and pedestal (shell) at present, be arranged with one group of silicon steel sheet on the skeleton, and skeleton is fixed on pedestal or other support plates by other modes again, makes whole device stable.Skeleton generally is fixed by dual mode at present, and a kind of is to be provided with four pins in the bottom surface of skeleton, offers on the pedestal and the corresponding jack of pin, cooperates with the inlay card of jack by pin, makes skeletal fixation on pedestal; The another kind of mode that adopts is: a metallic support is fixed on the silicon steel sheet that is set on the skeleton, metallic support is fixed on the pedestal again, by metallic support whole device is fixed.But all there is certain shortcoming in this dual mode, and at first pin is fixing not firm, and is loosening easily, causes product structure built on the sand; Secondly not only increase cost by the fixing mode of metallic support, and product is easy to generate noise in use.On the other hand, because the structure more complicated of skeleton can not realize a die sinking, so it is made up of symmetrical left and right sides two parts usually, like this in when assembling, locate cumbersome, need manual with left and right sides support fixing after, silicon steel sheet is being put, and fixing then, operation is loaded down with trivial details.
Summary of the invention:
The purpose of this utility model is to provide a kind of being convenient to fix, and the skeleton of the firm transformer of structure.
The utility model is achieved by the following technical solution: the lower end of skeleton is connected with a connecting seat, and offers the through hole that is used for the screw connection on the Connection Block.
Skeleton is made up of symmetrical left and right skeleton, and left and right skeleton promptly is provided with corresponding protruding tongue and groove by the connection of inlay card structure on the end face of left and right skeleton combination.
After adopting this structure, at first, offer on the affixed Connection Block in skeleton lower end and be used for the through hole that screw connects, thus when fixing skeleton only need with screw Connection Block is fixed on the pedestal and gets final product.Secondly, the end face of left and right sides skeleton combination is provided with corresponding protruding tongue and groove, can directly realize the location of left and right sides skeleton like this when assembling by the inlay card of protruding tongue and groove, and is simple, convenient.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a three-dimensional exploded view of the present utility model;
Fig. 3 is the user mode figure that the utility model makes another embodiment.
Embodiment:
See accompanying drawing 1,2, the lower end of skeleton 1 is connected with a connecting seat 12 in the utility model, and offers the through hole 121 that is used for the screw connection on the Connection Block 12.
Wherein skeleton 1 is made up of symmetrical left and right skeleton 13,14, and left and right skeleton 13,14 promptly is provided with corresponding protruding tongue 131,142 and groove 132,141 by the connection of inlay card structure on the end face of left and right skeleton 13,14 combinations.
When using present embodiment, at first the protruding tongue 131,142 and the groove 132,141 that are provided with of the end face by 13,14 combinations of left and right sides skeleton lumps together skeleton 13,14 locator cards, then silicon steel sheet is set in the middle of the skeleton 1, and silicon steel sheet fixed, with screw Connection Block 12 is fixed on the pedestal at last and gets final product.See accompanying drawing 1, in the present embodiment screw when mounted, from the bottom to top, promptly screw is inserted by pedestal, passes Connection Block 12, its top is connected with nut.See accompanying drawing 3, in the present embodiment, screw 2 can directly be inserted by Connection Block 12, is connected with pedestal 3.
Claims (2)
1, a kind of skeleton of transformer is characterized in that: the lower end of skeleton (1) is connected with a connecting seat (12), and offers the through hole (121) that is used for the screw connection on the Connection Block (12).
2, the skeleton of transformer according to claim 1, it is characterized in that: skeleton (1) is made up of symmetrical left and right skeleton (13), (14), and left and right skeleton (13), (14) connect by the inlay card structure, promptly are provided with corresponding protruding tongue (131), (142) and groove (132), (141) on the end face of left and right skeleton (13), (14) combination.
