As shown in the figure, the pull tape unidirectional threading type electrical connector 1 of this embodiment includes a circuit board 10, a plurality of cables C, an insulating structure 20, a housing member 30, a locking member 40, and a pull tape 50. The circuit board 10 includes a circuit board body 11, a plurality of contact conductors 12, and a plurality of pads 13. The plurality of contact conductors 12 and the plurality of pads 13 are respectively disposed near opposite ends of the circuit board body 11. The plurality of pads 13 are respectively electrically connected to the plurality of contact conductors 12 via the circuit of the circuit board body 11. The contact conductors 12 are used to contact the terminals of the mating electrical connector to form an electrical connection. The plurality of cables are respectively coupled to the plurality of pads 13 through the circuit board body 11.

[0027] The insulating structure 20 is coupled to the circuit board 10 and the plurality of cables C. The insulating structure 20 covers the pads 13 of the circuit board 10 and the cables 20, keeping the cables C on the circuit board 10 and protecting the soldering joints between the conductors of the cables C and the pads 13.

[0028] The housing member 30 includes a front housing portion 31 and a rear housing portion 32. The front housing portion 31 and the rear housing portion 32 are assembled by a snap-fit structure and cover the insulating structure 20 and the circuit board 10. The front housing portion 31 has a hollow sleeve shape to form a docking space 311 for docking with the mating electrical connector. The circuit board 10 is located within the docking space 311. A receiving groove 312 is formed on the top surface of the front housing portion 31. The receiving groove 312 is a structure recessed from the top surface towards the docking space 311. The receiving groove 312 is used to receive the locking member 40. The top surface of the front housing portion 31 further has a rib 313. The portion of the rib 313 spanning the receiving groove 312 forms a crossbar portion 314. The rear housing portion 32 has a flange 321 extending in a direction away from the housing member 30. The flange 321 is parallel to the circuit board 10. A first through groove 322 is formed on the flange 321. The opening direction of the first through groove 322 is perpendicular to the circuit board 10. The top surface of the rear housing portion 32 has a recessed portion 323. The bottom surface of the recessed portion 323 is flush with the top surface of the flange 321.

[0029] The locking fastener 40 is disposed in the receiving groove 312 of the outer housing 30. The locking fastener 40 includes a base portion 41 and a locking portion 42. The base portion 41 and the locking portion 42 are connected to each other and form a bent shape. The base portion 41 abuts against the bottom of the receiving groove 312, and the locking portion 42 is inclined relative to the base portion 41. The locking fastener 40 is made of a ductile material such as metal, and the locking portion 42 can be stress-deformed to move between a locking position and a release position. The locking portion 42 is away from the base portion 41 at the locking position, and the locking portion 42 is close to the base portion 41 at the release position. When the opposing electrical connector is docked with the strap one-way threading type electrical connector 1 of the present embodiment, the locking portion 42 is at the locking position and forms a lock with the opposing electrical connector. Moreover, when the locking portion 42 is at the locking position, it abuts against the crossbar portion 314 of the front outer housing portion 31. The locking portion 42 has a bent structure 421 at the end away from the base portion 41, and a second through groove 422 is formed at the bent structure 421.

[0030] The strap 50 has a strip-shaped body 51, a first end portion 52 and a second end portion 53 oppositely disposed at both ends of the strip-shaped body. The first end portion 52 passes through the first through groove 322 of the outer housing 30, and the second end portion 53 passes through the second through groove 422 of the locking fastener 40. The size of the first end portion 52 is larger than the size of the first through groove 322. Specifically, the dimension of the first end portion 52 in the direction parallel to the strip-shaped body 51 is larger than the dimension of the first through groove 322 in the direction parallel to the strip-shaped body 51, that is, the width of the first end portion 52 in the direction parallel to the strip-shaped body 51 is larger than the width of the first through groove 322. Thus, after the first end portion 52 passes through the first through groove 322 of the outer housing 30, the first end portion 52 can be retained and is not easily detached from the first through groove 322. The first end portion 52 and the strip-shaped body 51 are of an integrated structure. The size of the second end portion 53 is larger than the size of the second through groove 422. Specifically, the dimension of the second end portion 53 in the direction perpendicular to the strip-shaped body 51 is larger than the dimension of the second through groove 422 in the direction perpendicular to the strip-shaped body 51, that is, the thickness of the second end portion 53 is larger than the width of the second through groove 422. A convex block 531 is provided on the second end portion 53 of the present embodiment. The convex block 531 increases the thickness of the second end portion 53. The convex block 531 corresponds to one end of the locking portion 42 of the locking fastener 40 close to the outer housing 30. When the strap 50 moves in a direction away from the outer housing 30, the convex block 531 abuts against one end of the locking portion 42 close to the outer housing 30. The convex block 531 can be pre-molded with plastic and then bonded to the strip-shaped body 51 by adhesive or hot pressing. The strap 50 has a first bent structure 54 near the second end 53. When the strap 50 moves in a direction away from the outer housing 30, the first bent structure 54 abuts against one end of the locking portion 42 away from the outer housing 30, causing the locking portion 42 to move from the locking position to the release position. The strap 50 has a second bent structure 55, and the second bent structure 55 abuts against the flange 321 of the front outer housing portion 31.

[0031] Please refer toFigure 6 , the conductor part of the cable C is welded to the pad 13 of the circuit board 10. Please refer to Figure 7 , an insulating structure 20 is formed by an injection molding process, and the insulating structure 20 covers the pad 13 of the circuit board 10 and the cable C. Please refer to Figure 8 , the front housing part 31 and the rear housing part 32 are assembled to the insulating structure 20, and the front housing part 31 and the rear housing part 32 are assembled to each other by a snap-fit structure to form a housing part 30. Please refer to Figure 9 , the locking part 40 is arranged in the accommodation groove 312 of the housing part 30. Please refer to Figure 10 , the pulling belt 50 is assembled to the housing part 30 and the locking part 40, wherein the first end 52 of the pulling belt 50 passes through the first through slot 322 of the housing part 30, and the second end 53 of the pulling belt 50 passes through the second through slot 422 of the locking part 40 to complete the assembly.
