Description
Technical field
The utility model relates to electrical equipment technical field, especially a kind of pin shaft of dry-type transformer iron core connection.
Background technique
Dry-type transformer is widely used in local lighting, skyscraper, airport, the places such as harbour CNC mechanical equipment, simply
Say the transformer that dry-type transformer just refers to that iron core and winding are not immersed in insulating oil；Dry-type transformer is due to environmental protection at present,
Non-maintaining, good appearance is small in size, and noise is small, is widely used, but when installing the dry-type transformer, does not design
Cleverly component, be easy to appear connection it is unstable, it is unreliable, to bring security risk.
Utility model content
Therefore, be guarantee clamping piece and connector stabilization, the utility model provide herein it is a kind of design rationally, structure letter
Single, pin shaft easy to use can guarantee iron core reliable retention by reasonably designing, easy to loading and unloading；It is big by reasonably designing
Path part can be good at for connector connecting with clamping piece, while by being convenient for reasonably in big path outer end bevelling
The installation of the utility model.
The utility model is realized in this way constructing a kind of pin shaft of dry-type transformer iron core connection, including it is installed on
The large diameter portion of connector macropore and path part positioned at large diameter portion front end, wherein path is partly installed in the small of clamping piece
Kong Zhong；
The path portions end begins with coaxial tapped blind hole；
The large diameter portion inner face offers co-axial toroidal cavity；
The large diameter portion and small diameter portion point are integral.
Preferably, the large diameter portion rear end oblique angle Dao You；The small diameter portion sub-headend has oblique angle；It is easily installed.
Preferably, the large diameter portion and path partial cross section are circle, and axis collinear.
Preferably, which is steel alloy；It ensure that stiffness and strength when use by the material.
Preferably, the path partial-length is greater than the length of large diameter portion.
The utility model has the advantages that：
The utility model is designed reasonably, structure is simple, easy to use, by reasonably designing, can guarantee that iron core reliably presss from both sides
It holds, it is easy to loading and unloading；By reasonable designed size path portion, it can be good at for connector connecting with clamping piece, pass through simultaneously
Reasonably in big path outer end bevelling, the installation of the utility model has been convenient for it；Continuous assembly is smoothly implemented to complete, and guarantees that connection can
It leans on, solves the problems, such as assembling process technique.
By reasonably designing tapped blind hole, it can be realized end mounting screw or bolt be fixed, it can be with
Object is sandwiched in centre, plays the role of connection；Simultaneously by reasonably designing toroidal cavity, can pacified by the groove
Play the role of limit and positioning during dress.
The utility model is simple to manufacture simultaneously, and easy for installation, low in cost, using effect is good, is suitble to promote the use of.
