1. A solenoid actuator comprising:
a casing body having a receiving space defined therein;
a casing cover coupled to the casing body, wherein the casing cover includes a connector for transmission of power and signals;
a bobbin assembly installed in the receiving space;
a core coupled to and extending through the bobbin assembly, wherein the core has a working space defined therein;
a housing surrounding a lower end of the core protruding out of the bobbin assembly;
a plunger movably installed in the working space; and
a rod coupled to and extending through the core, wherein the rod moves under movement of the plunger,
wherein the bobbin assembly includes a bobbin terminal, and the casing cover includes a connector terminal,
wherein when the casing cover is coupled to the casing body, the connector terminal is connected to the bobbin terminal,
wherein one of the bobbin terminal or the connector terminal is embodied as a pin terminal, while the other thereof is embodied as a fork terminal,
wherein the connector terminal includes a pair of connector terminals, wherein the pair of connector terminals are spaced from each other by a spacer,
wherein the bobbin assembly includes a spool-shaped bobbin, and a coil wound around an outer circumferential face of the spool-shaped bobbin,
wherein a mount protrudes from a bottom face of the spool-shaped bobbin, and the mount has the bobbin terminal,
wherein the housing has a first groove defined therein into which the mount and the bobbin terminal are inserted,
wherein the mount has a guide groove defined therein into which the coil connected to the bobbin terminal is inserted,
wherein an insulating groove is formed in one side of the housing in which the first groove is formed, wherein the insulating groove spaces the casing body and the bobbin terminal from each other,
wherein a first embossing to prevent radial movement of the bobbin assembly protrudes from at least one of a top or a bottom of the outer circumferential face of the spool-shaped bobbin,
wherein a second embossing to prevent axial movement of the bobbin assembly protrudes from at least one of a top face or the bottom face of the spool-shaped bobbin,
wherein the casing body has a pipe shape having an open top face and an open bottom face,
wherein the casing cover has a cup shape surrounding a lower portion of the casing body,
wherein a groove is formed in an outer circumferential face of the casing body and a protrusion is formed on an inner circumferential face of the casing cover,
wherein when the casing body and the casing cover are coupled to each other, the protrusion is inserted into the groove such that the casing body and the casing cover are provisionally fastened to each other,
wherein a screw completely fixes together the casing body and the casing cover that are provisionally fastened to each other,
wherein a further groove is formed in the outer circumferential face of the casing body, wherein an O-ring sealing between the casing body and the casing cover is inserted into the further groove,
wherein the further groove is positioned above the groove in an assembly direction of the casing cover, and
wherein the solenoid actuator further comprises a screw passing through the casing cover and screw-coupled to the housing.
