A highly reliable resin-molded stator not suffering insulation breakdown between the different phases of the stator coils even when the operation mode where the output of a rotary machine using a resin-molded stator in which a stator coil wound around a plurality of slots and a stator coil provided at the stator core end are resin-molded is to be increased from the level under a stopped status to the maximum achievable level within a short time is repeated. Also disclosed is a method of manufacturing such a stator, and a rotary machine using the same. The resin-molded stator of the present invention comprises a stator core, electrically insulated stator coils wound around the plurality of slots or protrusions provided in the axial direction of the stator core, and molding resin with which are molded the stator core and the stator coils located at the aforementioned slots or protrusions and at the stator core end, wherein the resin-molded stator is characterized in that non-adhesive structure is established between the molding resin and at least one of the end faces of the stator core.

A pre-molded part is formed by pre-molding an insert with a pre-molded member, and then the pre-molded part is inserted into an over-molded member composed of thermo plastic resin. After applying a heat treatment with a temperature lower than a crystalline melting point of the pre-molded part to the pre-molded part surrounding the insert, a firm contact between the insert and the resin surrounding the insert without a gap at the interface between those parts is obtained.

摘要:
Continuous annular resin bands surrounding electrical contact portions of respective terminals are disposed without gaps between the electrical contact portions of respective terminals and resin members that fixedly hold the terminals; there are formed gaps among the adjoining resin bands. Gaps are formed among a bundle of terminals having annular resin bands and resin members surrounding the bundle. A partial adhesion is formed at the interface between the terminals and the resin by a low cost manufacturing method, whereby a molding with high air-tightness between the interior and exterior thereof and high reliability is realized.

A pre-mold part is formed by pre-molding the insert with the pre-molded part, and then the pre-molded part is inserted into the over-molded part composed of thermo plastic resin. After applying a heat treatment with the temperature lower than a crystalline melting point of the pre-molded part to the pre-molded part surrounding the insert formed as the composite mold part surrounding the pre-mold part, a firm contact between the insert and the resin surrounding the insert part without no gap at the interface between those parts is obtained.
摘要:
An integrally multiple-molded part for electronic devices is provided capable of absorbing and relieving the internal stresses of a multiple-molded part, preventing the occurrence of clearances between the bonding side face of each electrical connection terminal and a resin, obtaining stable frictional force at the contact region between the bonding surface of the electrical connection terminal and an aluminum wire, obtaining the energy required for bonding, and achieving high bondability. The surface of the molded electrical connection terminal section formed as a primary-molded article becomes exposed after secondary molding, and a stress-absorbing structure is formed in the primary molding resin section of the primary-molded article that serves as a transmission path for stresses associated with the resin shrinkage occurring when the secondary molding resin is cured.
