The C-shaped part is provided with a locking point, and the stop is closed by engaging with the first insulating body through the locking point.
[0008] A further aspect of the above solution is that the first terminal has a soldering foot extending from the core, which is soldered to the circuit board, and the housing has at least two fixing feet that are fixedly connected to the circuit board.

[0011] A further improvement in the above scheme is that the locking point is a protruding pin, and the first insulating body is provided with a corresponding locking hole, and the locking point is inserted into the locking hole to form a locking connection.
[0012] A further improvement in the above scheme is that the end of the C-shaped portion has a hand-held step portion.

[0017] See Figure 1 , 2 Figures 3, 4, 5, and 6 are schematic diagrams of a preferred embodiment of this utility model. This utility model relates to an anti-detachment connector, which includes a female connector and a male connector that are connected to each other to enable the transmission of current or signals between different devices. Furthermore, the female connector is mounted on a circuit board, while the male connector is connected to a wire to achieve a board-to-wire connection.
[0018] The female connector has a first insulating body 1 and a first terminal 2. The mating end of the first insulating body 1 has an axially recessed socket 11 for connecting with a male connector. A first guide portion 111 is provided on the inner wall of the socket 11. Preferably, the first guide portion 111 is a guide groove formed on the inner wall of the first insulating body 1. The first guide portion 111 is integrally manufactured with the first insulating body 1, resulting in a stable and reliable structure. The first terminal 2 is mounted on the first insulating body 1 and has a first contact portion 21 facing the socket 11. The male connector has a second insulating body 3 and a second terminal 4. The shape of the second insulating body 3 is adapted to be inserted into the socket 11 of the first insulating body 1, and a second guide portion 31 is provided on the outer surface of the second insulating body 3. The second guide portion 31 is preferably a protruding rib, and its shape and size match the first guide portion 111. Through the cooperation of the second guide portion 31 and the first guide portion 111, the second insulating body 3 is guided into the socket 11, improving the mating accuracy and effectively preventing relative rotation of the male and female connectors after mating, thereby improving connection stability. The second terminal 4 is mounted on the second insulating body 3 and has a second contact portion 41, which is used to make contact with the first contact portion 21 of the first terminal 2 for conduction. In this embodiment, the second contact portion 41 is in the form of a pin, and the first contact portion 21 is a U-shaped state with multiple sides, realizing the effect of multi-sided clamping contact of the first contact portion 21 with the second contact portion 41, improving the contact surface and obtaining better conduction performance. It also includes a stop 5, which is disposed on the mating end of the first insulating body 1 and can open and close. The stop supports the second insulating body 3 in the closed state, thereby restricting the movement of the second insulating body 3 in the insertion direction, which can effectively improve the axial holding force and effectively prevent the male head from automatically withdrawing and falling off.
[0019] Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, in this embodiment, the first insulating body 1 is constructed by combining a hollow cylindrical outer shell 12 and a rubber core 13. The outer shell 12 is fitted onto the rubber core 13, facilitating manufacturing and assembly. The first terminal 2 is fixed to the rubber core 13. Preferably, the first terminal 2 is implanted onto the rubber core 13. The rubber core 13 has an insertion hole 131, which is adapted to accommodate the insertion of the second contact portion 41 of the second terminal 4, allowing the second contact portion 41 to make contact and conduct with the first contact portion 21. The shape of the rubber core 13 matches the second insulating body 3, so that the rubber core 13 and the second insulating body 3 are axially superimposed together inside the outer shell 12. The rubber core 13 is provided with a third guide portion 132. Preferably, the third guide portion 132 is also an outwardly protruding rib, and the shape and size of the third guide portion 132 match the first guide portion 111. When the outer shell 12 is fitted onto the rubber core 13, the third guide portion 132 and the first guide portion 111 cooperate to assemble, providing guidance and limiting, preventing relative rotation, and improving connection stability.
[0020] The first terminal 2 has a welding foot 22 extending from the core 13, which is welded to the circuit board 6. The outer shell 12 has at least two fixing feet 121, which are fixedly connected to the circuit board 6 to achieve upper board welding assembly. The insertion hole 131 of the core 13 is a stepped hole. The insertion hole 131 is constructed with a guide section 1311, a positioning section 1312, and a terminal receiving section 1313 in sequence according to the insertion direction of the second contact part 41. The guide section 1311 is flared. The diameter of the positioning section 1312 matches the outer diameter of the second contact part 41, while the diameter of the terminal receiving section 1313 is larger than that of the positioning section 1312. The guide section 1311 is used to guide the insertion of the second contact part 41, and the positioning section 1312 is used to guide the insertion of the second contact part 41 and restrict the second contact part 41, thereby improving the convenience and accuracy of insertion assembly. The terminal receiving section 1313 is used to receive the first contact portion 21 of the first terminal 2, so that the end of the first contact portion 21 can be hidden on the back side of the positioning section 1312, which can effectively avoid interference and deformation between terminals when male and female are inserted, and ensure service life.
[0021] In this embodiment, the stop 5 has a rotating part 51 and a C-shaped part 52 extending from the rotating part. The rotating part 51 is hinged to the first insulating body 1, and the C-shaped part 52 is used to press against the second insulating body 3. The C-shaped part 52 is provided with a locking point 521. The stop is closed by engaging the locking point 521 with the first insulating body 1. The shape and size of the C-shaped part 52 meet the requirements of contacting and pressing against the rear end of the second insulating body 3, and obtain a longer contact support line to ensure the support force. At the same time, the C-shaped part 52 has a hollow area so that the wiring part reserved on the second terminal 4 can be connected to the wire. At the same time, the C-shaped part 52 is expandable and retractable so that pressing the C-shaped part 52 can make the locking point 521 engage or disengage from the first insulating body 1. In this embodiment, the locking point 521 is a protruding pin, and the first insulating body 1 is provided with a corresponding locking hole 14. The locking point 521 engages with the locking hole 14 to form a locking connection. Utilizing the expandable and retractable nature of the C-shaped portion 52, the locking point 521 and the locking hole 14 can be released by pressing, thereby allowing the stop 5 to be rotated open. In this embodiment, the end of the C-shaped portion 52 has a hand-held step 522, which facilitates hand-held pressing and improves operational convenience.
[0022] This utility model has a simple structure, is easy to manufacture and assemble, and has low investment costs. It effectively restricts the normal and axial movement of the male connector after the male and female connectors are inserted, improving the accuracy and stability of the connection. The closing support of the stop component achieves the effect of preventing the male connector from falling off.
