[0021] Example

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a blade-type CTB connector includes a connector 1 and a plug connector 2. The plug connector 2 can be movably plugged into the rear end of the connector 1 by plugging and unplugging. The rear end of the plug connector 2 is fixedly connected to a plurality of connecting wires 3 and extends to the interior of the plug connector 2. Blade contacts 4 are symmetrically arranged inside the connector 1. The tail ends of the blade contacts 4 extend to the outside of the bottom end of the connector 1 for conducting current when the connector is working. Plug contacts 5 are symmetrically arranged inside the plug connector 2. When the connector 1 and the plug connector 2 are plugged together, the blade contacts 4 and the plug contacts 5 are electrically connected together and transmit current to the connecting wires 3 at the rear end.

[0023] The connector 1 is composed of a shell, a blade contact 4 and a PCB board 101. The PCB board 101 is movably plugged into the bottom of the connector 1. A connecting guide column 102 is symmetrically fixedly connected to the bottom end of the shell of the connector 1. The blade contact 4 is fixedly plugged into the inside of the shell of the connector 1.

[0024] The upper end of the PCB board 101 is provided with a plurality of contact grooves 1011 and fixing grooves 1012. When the connector 1 is assembled, the blade contact 4 can be movably inserted into the contact groove 1011, and the connecting guide column 102 can be correspondingly inserted into the fixing groove 1012. Two connecting guide columns 102 with a diameter of 10.20 mm are added to the outer shell of the connector 1 to assemble the connector 1 to the PCB board 101, thereby enhancing the holding force between the PCB head and the PCB board 101 to prevent the outer shell of the connector 1 from falling off from the PCB board 101 when the plug connector 2 is forcibly pulled out of the connector 1.

[0025] The plug connector 2 is assembled from a connector secondary lock 21, a plug contact 5, a terminal secondary lock 6 and a fixed base 31. The plug contact 5 is fixedly connected to the connecting wire 3 through a crimping process. The connector secondary lock 21 is used to protect the pairing of the connector 1 and the plug connector 2. The connector secondary lock 21 can only be moved forward when the connector 1 and the plug connector 2 are fully assembled. Therefore, locking the connector secondary lock 21 (moving it forward) can detect whether the connector has been fully assembled; when the connector secondary lock 21 is locked, the latch cannot be pressed down, so the connector secondary lock 21 can prevent the connector from being separated due to misoperation of the latch. Furthermore, after the pairing of the connector 1 and the plug connector 2 is completed, it can be detected whether the connector has been fully assembled to prevent the connector from falling off due to misoperation.

[0026] The bottom end of the blade contact 4 is provided with a conical contact tail 41, and the side of the blade contact 4 is provided with a burr 42. The tip portion of the contact tail 41 provides a guiding function when the blade contact 4 is inserted into the PCB board (101), thereby preventing the blade contact 4 from being unable to be inserted into the PCB board (101) due to a manufacturing error of the parts; and each blade contact has two sets of symmetrical burrs 42, which are used to provide a retaining force between the housing and the blade contact, thereby preventing the blade contact 4 from falling off the housing when a thrust is generated when mating with the plug connector 2.

[0027] The plug contact 5 is assembled by a front cover 51 and a connecting body 52. ​​The connecting body 52 is clamped inside the front cover 51 and extends to the outer end of the plug contact 5. The clamp 521 of the connecting body 52 is used to clamp the connecting wire 3. After the plug contact 5 is inserted into the plug connector 2, the plug contact 5 is fixed by the terminal secondary lock 6.

[0028] When the utility model is used, the plug connector 2 can be movably plugged into the rear end of the connector 1 by plugging and unplugging. When the connector 1 and the plug connector 2 are plugged together, the blade contact 4 and the plug contact 5 are electrically connected together and transmit current to the connection line 3 at the rear end. The blade contact 4 can be movably plugged into the inside of the contact slot 1011, and the connecting guide column 102 can be correspondingly plugged into the fixing slot 1012 to assemble the connector 1. The connecting body 52 is clamped inside the front cover 51 and extends to the outer end of the plug contact 5. The clamp 521 of the connecting body 52 is used to clamp the connection line 3 to assemble the plug connector 2.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
