A process for the obtention of intra uterine contraceptive device and intra uterine contraceptive device, the totally mechanized process (P) is responsible for the contraceptive device (1) assembling, the device (1) is formed by a T-piece (2) having top parts (2a) with copper tubes (3), the vertical part (2b) is reeled by a copper wire (4), the part (2c) presents a hole (2d) receiving a cord (5) for extraction. The present invention, the process (P) comprises the folowing steps: a) robotized station (R) for obtain the T-pieces (2) having top parts (2a) are injected into the tubes (3), for forming a single piece; b) conveyor belt conduction to a copper wire reeling station for reel the part (2b) with a copper wire (4), the reeling is performed by a special machine having a micro motor which is able to make a synchronized reel movement; c) conveyor belt conduction to a manual cord insertion (5), d) totally assembled device (1) conduction to the mechanical station for insertion in applicator body (6); e) mechanical station for separated packaging of the applicator (6) containing the device (1), the outter tube (7) and the piston (8); f) packaging of sets of ready to use applicators in boxes; g) sterilization. The resulting product is obtained by the referred process (P) and comprises an applicator body (6), formed by two identical pieces (6a) and (6b) being complementars by pins (6c) connection. Each piece (6a-6b) has a longitudinal channel (6d) and narrowed edges (6e); the inner part of these edges (6e) is provided a transversal channel (6f) which are concurrent in relation to the channel extremity (6d) due the curves (6g). The outter side of the narrowed extremities (6e) are threaded (6h) in order to receive the complementar extremity of the conductor tube (7); at the crossing portion formed by the channels (6d) and (6f) is placed the device (1) and the cord (5) is placed in the remaining part of the channel (6d).
