[0031] As shown in FIG. 1 and FIG. 2, the present invention proposes a composite pull tab 1, wherein the pull tab 1 comprises two metal decoration parts (2, 4) spaced from each other, namely a first metal decoration part 2 and a second metal decoration part 4; and a certain distance is kept between the first metal decoration part 2 and the second metal decoration part 4 so that the two metal decoration parts are not subjected to direct contact conduction. A connecting through hole 210 is formed in an inner leg portion 21 of the first metal decoration part 2; a connecting through hole 410 is formed in an inner leg portion 41 of the second metal decoration part 4; and an electrostatic eliminating unit 5 is electrically connected between the inner leg portions of the two metal decoration parts (2, 4) so that static electricity on a human body is conducted to the electrostatic eliminating unit 5 through the metal decoration part (2 or 4) when a human hand touches one metal decoration part (2 or 4), and power consuming is realized by the electrostatic eliminating unit 5, thereby removing the static electricity on the human body, wherein the inner leg portions and the outer leg portions of the metal decoration parts (2, 4) are named after their relative directions; and a side leg portion which is close to and encapsulated into the plastic encapsulation part 3 is named as the inner leg portion, while the opposite one is named as the outer leg portion.

[0032] The pull tab 1 further comprises a plastic encapsulation part 3; the plastic encapsulation part 3 is welded on the inner leg portion 21 of the first metal decoration part 2 and the inner leg portion 41 of the second metal decoration part 4 and fills the connecting through holes (210, 410) so as to fixedly connect the two metal decoration parts (2, 4) into a whole; the electrostatic eliminating unit 5 is accommodated in the plastic encapsulation part 3; and an outer leg portion 20 of the first metal decoration part 2 and an outer leg portion 40 of the second metal decoration part 4 are respectively exposed outside the plastic encapsulation part 3.

[0033] Wherein, the plastic encapsulation part 3 is welded on the inner leg portion 21 of the first metal decoration part 2 and the inner leg portion 41 of the second metal decoration part 4 and fills the connecting through holes (210, 410) so as to fixedly connect the two metal decoration parts (2, 4) into a whole; the above features define a connection relationship between the plastic encapsulation part 3 and each of the two metal decoration parts (2, 4); the plastic encapsulation part 3 is an intermediate connecting part for fixedly engaging the two metal decoration parts (2, 4) into a whole; and the two metal decoration parts cannot be easily split after fixedly connected into a whole, unless subjected to destructive split. In addition, the above features also define a connection process between the plastic encapsulation part 3 and each of the metal decoration parts (2, 4); during manufacture, the plastic encapsulation part 3 is integrally molten in a heating manner, is placed between the two metal decoration parts (2, 4) and fills the connecting through holes (210, 410); the inner leg portions of the metal decoration parts (2, 4) are tightly connected together by means of plasticity of plastics after the plastic encapsulation part 3 is cooled; and the plastic encapsulation part 3 and the connecting through holes (210, 410) are combined to hinder the metal decoration parts (2, 4) from separating from the plastic encapsulation part 3 so that the plastic encapsulation part 3 and the two metal decoration parts (2, 4) have excellent structural strength and structural stability, and the metal decoration parts (2, 4) cannot be separated from the plastic encapsulation part 3 even if the pull tab 1 is pulled on the zipper for long term. In addition, the plastic encapsulation part 3 is welded together with the metal decoration parts (2, 4) so that excellent water tightness is formed between the plastic encapsulation part 3 and each of the metal decoration parts (2, 4), thereby preventing the liquid from infiltrating into the plastic encapsulation part 3 to damage the electrostatic eliminating unit 5, greatly simplifying a sealing structure between the plastic encapsulation part 3 and each of the metal decoration parts (2, 4), and improving sealing stability between the plastic encapsulation part 3 and each of the metal decoration parts (2, 4).

[0035] The electrostatic eliminating unit 5 comprises the power consuming element and a conducting wire; the power consuming element comprises a luminous body 50 and a resistor 51; and a light-transmitting region provided to correspond to the luminous body is provided on the plastic encapsulation part 3 so that the luminous body 50 can emit light and consume electrostatic energy when the static electricity of the human body flows through the luminous body, and a user can also learn about consumption conditions of the static electricity through lighting conditions of the luminous body.

[0036] In order that the electrostatic eliminating unit 5 is provided in the plastic encapsulation part 3 as middle as possible and is not protruded from a surface of the plastic encapsulation part 3 due to biasing to affect the appearance and electrostatic eliminating effect of the pull tab 1, the following technical solutions can further be adopted:

[0037] In a first embodiment, the structure of the present embodiment is similar to the structures shown in FIG. 1 and FIG. 2, thereby omitting a specific view. The plastic connecting body for wrapping the electrostatic eliminating unit 5 is welded between the inner leg portions of the two metal decoration parts (2, 4) in advance; and the plastic encapsulation part 3 is welded and wrapped on the plastic connecting body, thereby fixing the electrostatic eliminating unit 5 first by means of the plastic connecting body so as to ensure that the electrostatic eliminating unit is provided away from the surface of the plastic encapsulation part 3 and is not protruded from the surface of the plastic encapsulation part 3.
