[0023] To address the issue of unstable connection between male and female connectors and prevent loosening and detachment during connection, this invention provides a wire-to-board connector.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 This utility model provides a wire-to-board connector, including a housing 1, a docking box 2 movably inserted into one end of the housing 1, a metal cover 4 covering the upper end of the housing 1, a pull rope 3 fixedly sleeved on one side of the metal cover 4, and a connecting wire 5 fixedly inserted into the rear end of the housing 1.

[0026] The housing 1 and the connecting box 2 are the outer shells of the male and female ends of the connector, respectively. When the housing 1 and the connecting box 2 are in the docking state, the pull rope 3 can be pulled to pull the metal cover 4, so that the metal cover 4 can drive the housing 1 to detach from the connecting box 2, thus completing the disconnection between the connectors.

[0027] Please see Figure 2 In some embodiments, a metal contact 21 is fixedly inserted inside the connection box 2, and a circuit board 22 is fixedly connected to the bottom end of the connection box 2.

[0028] The connector box 2 has multiple slots inside to accommodate metal contacts 21. During use, the metal contacts 21 are snapped into the slots inside the connector box 2 to achieve a fixed connection and ensure the normal use of the connector.

[0029] Please see Figure 4 In some embodiments, a protruding partition 24 is provided at the connection between the inside of the docking box 2 and the metal contact piece 21, and a slot 25 is provided at the upper part of the middle position of the connection end of the docking box 2.

[0030] After the metal contact 21 is assembled with the docking box 2, the docking box 2 is designed with a partition 24 between the contact arms of the metal contact 21 to prevent the metal contact 21 from rotating poorly after assembly and to provide a positioning constraint for the contact arms of the metal contact 21. The connecting end of the box body 1 is provided with a connecting and fixing structure at the position corresponding to the slot 25. After the connecting box 2 of the box body 1 is docked, the connecting and fixing structure of the box body 1 can be snapped into the inside of the slot 25.

[0031] Please see Figure 2 In some embodiments, one end of the pull rope 3 is fixedly connected to a pull tab 31.

[0032] One end of the pull cord 3 is fixedly connected to the metal cover 4, and the other end is provided with a rectangular pull tab 31. When disassembling the male and female connectors, the user only needs to pull the pull tab 31 to pull the metal cover 4 with the pull cord 3, so that the metal cover 4 drives the box 1 to detach from the connector box 2, making it convenient for the user to disassemble the connector.

[0033] Please see Figure 5 In some embodiments, an unlocking boss 41 is fixedly connected to the middle of the back of the metal cover 4, a stop boss 42 is provided at the front end of the unlocking boss 41, and a pull rope mounting hole 43 is fixedly connected to the front end of the metal cover 4.

[0034] The fixed end of the pull rope 3 is fixedly connected to the metal cover 4 by passing through the mounting hole 3, which makes it convenient to directly control the metal cover 4 using the pull rope 3.

[0035] Please see Figure 2 One end of the connecting line 5 is fixedly sleeved with a heat shrink sleeve 51, and the front end of the heat shrink sleeve 51 is fixedly connected with a power contact 6 and a signal contact 7.

[0036] The interior of the housing 1 has multiple slots for accommodating power contacts 6 and signal contacts 7. When assembling the housing 1, the contacts 6 and signal contacts 7 are fixed by snapping them into the interior of the housing 1, so that the housing 1 forms one end of the connector, ensuring the normal use of the connector.

[0037] Please see Figure 3 In some embodiments, the upper surface of the box body 1 is provided with symmetrical hooks 8 at the middle position, and the middle position of the hooks 8 is rotatably connected to the positioning post 81. The bottom end of the positioning post 81 is fixedly connected to the surface of the box body 1, and a spring 82 is fixedly connected between the two hooks 8.

[0038] The connection and fixing structure at the connection end of the box body 1 corresponding to the position of the slot 25 is the structure of the two hooks 8. When the box body 1 and the docking box 2 are inserted, the hooks 8 slide into the inside of the slot 25. When the front end of the hooks 8 contacts the inner wall of the slot 25, the hooks 8 are squeezed and rotate inward. At this time, the spring 82 is compressed. When the hooks 8 are fully inserted into the inside of the slot 25, the inner wall of the slot 25 is disengaged from the hooks 8. The spring returns to its original shape and generates a reverse force to push the hooks 8 on both sides to open. The front end of the hooks 8 is provided with a barb structure, so that the opened hooks 8 are locked inside the slot 25, realizing the fixed connection between the box body 1 and the docking box 2.

[0039] The surface of the docking box 2 is provided with symmetrical locking holes 26. The locking holes 26 cooperate with the hooks 8 to form a fixed connection between the box body 1 and the docking box 2. The side of the power contact 6 is provided with a terminal locking piece 61. The terminal locking piece 61 ensures that the terminal is correctly and securely positioned in the connector and prevents the terminal from loosening or shifting under the action of vibration, impact or other external factors.

[0040] When this utility model is in use, when the housing 1 and the docking box 2 are inserted, the hook 8 slides into the inside of the slot 25. The front end of the hook 8 is provided with a barb structure, so that the opened hook 8 is locked inside the slot 25, realizing the fixed locking between the housing 1 and the docking box 2. When it is necessary to disassemble the connector, simply pull the pull tab 31, which drives the pull rope 3 to pull the metal cover 4. The metal cover 4 covers the upper end of the hook 8, and the unlocking protrusion 41 is provided on the back of the metal cover 4. The unlocking protrusion 41 is located at the lower end of the spring 82 and is between the two hooks 8. When the metal cover 4 is pulled, the unlocking protrusion 41 moves to the outside of the tail end of the hook 8, so that the tail end of the hook 8 opens. At this time, the front ends of the two hooks 8 will move closer due to the opening of the tail end, and the hook 8 is released from the lock between the slot 25. At this time, continue to pull the pull tab 31 to pull the housing 1 out of the docking box 2, and complete the disassembly of the connector.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
