Connecting terminal for rotary transformer and manufacturing method thereof

Abstract

The invention provides a connecting terminal for a rotary transformer and a manufacturing method thereof. One end of the connecting terminal is connected with a winding lead-out wire of the rotary transformer, while the other end is connected with a plug lead-out wire; the section of one end of the connecting terminal connected with the winding lead-out wire is C-shaped, and the end is provided with at least one arc concave surface; the junction of the arc concave surface and the outer surface of the end with the C-shaped section is in smooth transition at least along the winding direction; and the arc concave surface is used for wrapped connection with the winding lead-out wire of the rotary transformer. Through the technical scheme, the section of one end of the connecting terminal connected with the winding lead-out wire is C-shaped, and the end is provided with at least one arc concave surface for wrapped connection with the winding lead-out wire of the rotary transformer, so a problem that the winding lead-out wire of the rotary transformer is easy to damage and break due to stress generated by edge angles is avoided. Meanwhile, the whole terminal is made of stamping parts, and has the advantages of saving materials and reducing production cost compared with the conventional square terminal.

Description

technical field [0001] The invention relates to the field of rotary transformers, in particular to a connection terminal structure of a rotary transformer and a manufacturing method thereof. Background technique [0002] As we all know, the resolver is widely used in the field of motors as a detection component for detecting the position of the motor rotor. The structure of the lead wire of the resolver is an intermediary mechanism for the exchange and circulation of internal information and external information of the resolver, which has a great influence on the performance of the resolver. Therefore, the connection stability of the resolver lead wire structure has become an issue that must be considered in the resolver assembly process. [0003] figure 1 Shown is a schematic diagram of the structure of an existing rotary transformer lead-out line. In the figure, one end of the resolver terminal 1 is connected to the lead-out line 4 of the resolver winding, and the other e...
