Problems solved by technology
[0010] The object of the present invention is to provide a connection terminal installation structure to solve the above-mentioned technical problems, that is, when the connection terminal installation structure is adopted, it can not only limit the insulation support The expansion of the part can also prevent the connection terminal from being embedded in the bad press-fit state, and it can also limit the looseness of the connection terminal after being pressed into the insulating support part

Embodiment Construction
[0026] Below, refer to the attached Figure 1~3 Embodiments of the present invention will be described. figure 1 and figure 2 The stator 1 shown in has a stator core 10 , a stator coil 15 , a base plate 20 and coil terminals 30 .
[0027] The stator core 10 has a substantially cylindrical shape and is formed by assembling two left and half sheet laminates 10A and 10B. Two engaging grooves 11 extending in the longitudinal direction are respectively formed on the outer peripheral surfaces of the half sheet laminates 10A and 10B, and the engaging claws 21 of the bottom plate 20 are respectively engaged in the engaging grooves 21 as described below. middle.
[0028] The stator coil 15 is composed of a first stator coil 15A and a second stator coil 15B. The first and second stator coils 15A and 15B are respectively wound on half of the sheet laminates 10A and 10B. The first stator coil 15A is fixed to the inner surface of half of the sheet laminate 10A, and the second stator...

The invention provides an installation structure of a connection terminal. With the installation structure, not only the outward extension of an insulating supporting part is limited, but also the embedment of a connection terminal at a poor pressing state is limited, and the looseness generated after the connection terminal is pressed into the insulating supporting part is also limited. An insulating supporting part (25) is disposed on the upper surface (12) of a stator iron core (10) winded with a stator coil (15), and the insulating supporting part and the stator iron core become one. A plate-like connection terminal (30) is pressed into the insulating supporting part and is electrically connected with an end part of the stator coil, and the connection terminal extends upwardly from the insulating supporting part. The connection terminal comprises a pair of arm parts (32) which extend out in the width direction of the connection terminal respectively, and the pair of arm parts are inverted L shaped with the respective end parts bending to the lower part of the connection terminal. With the connection terminal being pressed into the insulating supporting part, the pair of arm parts are locked at the outer surface of the insulating supporting part, therefore the outward extension of the insulating supporting part in the width direction of itself is limited.
Description
technical field [0001] The present invention relates to a mounting structure of a connection terminal which is pressed into an insulating support member provided integrally with a stator core and electrically connected to an end portion of a stator coil. Background technique [0002] For example, Patent Document 1 of the prior art discloses a press-fit fixing type connector structure in which vertical bending of the connector is restricted near a position where the connector is press-fitted into a circuit board or the like and fixed. or deformed structures. When the press-fit fixing type connector described in Patent Document 1 is used, since the large-width portion to which a pressing force is applied during the press-fit operation and the fixing portion located near the large-width portion and fixed to a circuit board or the like The boundary area between them is formed in the Japanese Katakana "コ" shape with strong bending stress in the thickness direction of the connect...
