A waterproof socket-type halogen lamp for a livestock barn with improved handling, comprising:
- a socket part (100) which is constituted by a fixing body (10) forming a hollow part in which a wire (40), an annular insulator (50), and a spring (60) are embedded,
- a side plate (20) finishing the outside of the fixing body (10),
- a contact point (30) which is positioned inside the annular insulator (50) and coupled to an inner end of the wire to electrically contact one terminal of the tube halogen lamp (200),
- the wire (40) which supplies power to the contact point (30) through the hollow part after passing through the side plate (20),
- the annular insulator (50) insulating the fixing body (20) from the contact point (30) after being inserted and seated in the inside of the hollow part,
- the spring (60) which is embedded in the hollow part and of which an outer side is supported by the side plate (20), an inner side supports the outer side of the annular insulator (50) to provide restoration force while supporting one terminal of the tube halogen lamp (200) through the contact point (30), and
- an inner waterproof packing (80) which prevents moisture or dust from penetrating to the inner end of the fixing body (10) and has a closed curve shape with a terminal passing groove (85) through which a lamp terminal housing (210) passes;
- and
- a tube halogen lamp (200) in which lamp terminals at both ends are connected with the contact point (30) by two socket parts (100),
- wherein the contact point (30) includes a contact terminal (30) protruding inward a front end, an extended locking part (33) which is extended to be larger than a diameter of the curved contact part (31) at the center, and a wire connection part (35) which is formed outside the extended locking part (33) and of which a front strand of the wire (40) is inserted to a wire coupling part (35a) at the rear end and pressed to have a flat shape,
- the annular insulator (50) includes a cylindrical body (51), a rectangular through hole (53) which is formed at the center of the cylindrical body (51) and has a horizontal width larger than a vertical width, a locking part support surface (55) which is formed at a portion which is more recessed than an inner surface (51a) of the cylindrical body (51) to contact-support the outer surface (33a) of the extended locking part (33), and a spring support part (57) which protrudes from the outside of the cylindrical body (51) and protrudes to be smaller than a median diameter of the cylindrical body (51),
- when the extended locking part (33) contacts the locking part support surface (55) by passing an assembly of the contact point (30) and the wire (40) toward the outside from the inside through the rectangular through hole (53), the wire coupling part (35a) having the flat shape does not pass through the rectangular through hole (53) by rotating the assembly of the contact point (30) and the wire (40) to be fixed, and
- the wire coupling part (35a) having the flat shape passes inwardly through the rectangular through hole (53) by rotating the assembly of the contact point 30 and the wire (40) to expose the contact point (30) outward the annular insulator (50).
