[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] See also Figures 1 to 3 As shown, a connector with a wire locking function of the utility model includes a plastic body 1 and a terminal 2 installed in the inner cavity of the plastic body 1, the plastic body 1 wraps the terminal 2 to protect the terminal 2 and acts as an insulator; the terminal 2 is provided with two wire locking springs 21 for locking the wire, and the two wire locking springs 21 can be close to or away from each other; the plastic body 1 is provided with a button 11, and the button 11 is provided with an unlocking protrusion 12, and the unlocking protrusion 12 is used to push open and unlock the two wire locking springs 21. The number of terminals 2 can be set accordingly according to actual needs, and the plastic body 1 also changes in volume with the change in the number of terminals 2 to ensure that all terminals 2 can be installed and protected. One end of the two wire locking springs 21 is close to each other and the other end is far away from each other to form an angle. The wire is inserted between the two wire locking springs 21 and is clamped and locked by the elastic force of the two wire locking springs 21 themselves. The wire is connected to the terminal 2 and locked and cannot fall off; when the wire needs to be unlocked, press and hold the button 11, and the unlocking protrusion 12 on the button 11 will be inserted between the two wire locking springs 21 to push the two wire locking springs 21 apart, thereby releasing the locking effect of the two wire locking springs 21 on the wire.

[0025] The connector with wire locking function uses the wire locking spring piece 21 designed on the terminal 2 itself to quickly lock the wire, and can also use the unlocking protrusion 12 on the button 11 of the plastic body 1 to unlock the wire. The function of fast locking and unlocking can be achieved without the aid of screws and other tools. It is easy to use, has a simple structure, few parts, and low cost.

[0026] See also Figures 2 to 3 As shown, the terminal 2 includes a body 22, two wire locking springs 21 are respectively connected to the two sides of the body 22, and are bent at a certain angle relative to the body 22, so that the two wire locking springs 21 have a certain elasticity and can have a clamping angle; the two wire locking springs 21 are both provided with pressing teeth 23, the ends of the two wire locking springs 21 with the pressing teeth 23 are close to each other, and the ends of the two wire locking springs 21 connected to the body 22 are far away from each other, and the pressing teeth 23 are used to press on the wire to achieve wire locking, and the pressing teeth 23 are wavy. Arranging multiple pressing teeth 23 can increase the contact points between the wire locking spring 21 and the wire, thereby enhancing the clamping force of the wire locking spring 21 on the wire.

[0027] See also Figures 2 to 3As shown, a guide piece 24 is provided on one side of the two locking wire spring pieces 21 close to the unlocking protrusion 12. The two guide pieces 24 are expanded outwardly, and the end of the guide piece 24 close to the pressing tooth 23 has a guiding effect on the unlocking protrusion 12, so that when the unlocking protrusion 12 is squeezed between the guide pieces 24, the two locking wire spring pieces 21 can be easily pushed open, thereby achieving the purpose of quick unlocking.

[0028] See also Figure 1 to Figure 2 As shown, the button 11 is arranged on one side of the plastic body 1, one end of the button 11 is connected to the side wall of the plastic body 1, the side wall of the plastic body 1 is provided with a clearance gap 13, the button 11 is located in the clearance gap 13, and the unlocking protrusion 12 is located at the lower end of the button 11 and is formed by protruding inward from the inner side of the button 11. The button 11, the unlocking protrusion 12 and the plastic body 1 are an integrated structure, and the connection between the button 11 and the plastic body 1 has a certain elasticity, which is convenient for pressing to unlock and reset, and the clearance gap 13 facilitates the movement of the button 11.

[0029] See also Figure 3 As shown, the terminal 2 also includes a reinforcing plate 25. The reinforcing plate 25 is designed to be bent in the same manner as the wire locking spring 21. The reinforcing plate 25 is connected to the main body 22 and is attached to the outer side of the wire locking spring 21. The reinforcing plate 25 can increase the strength of the wire locking spring 21, and is therefore used to prevent the wire locking spring 21 from undergoing plastic deformation due to multiple unlockings, thereby avoiding failure of the locking function of the wire locking spring 21.

[0030] See also Figure 1 to Figure 2 As shown, a plug hole 14 is provided on the top of the plastic body 1, and the plug hole 14 is connected to the inner cavity and directly passes through two wire locking springs 21. The number of the plug holes 14 is the same as the number of the terminals 2. The wire is inserted from the plug hole 14 into the inner cavity of the plastic body 1 to connect with the terminal 2 and be locked. The angle openings of the two wire locking springs 21 are set toward the plug hole 14.

[0031] See also Figure 1 As shown, it also includes a PCB board 3, which is mounted on the lower end of the plastic body 1 and electrically connected to the terminal 2. Two pins are provided at the end of the terminal 2 away from the socket 14, and the two pins are electrically connected to the PCB board 3 respectively. Mylar sheets can be used for insulation packaging treatment at the place where the terminal 2 is not connected to the PCB board 3.

[0032] See also Figure 2 As shown, two support blocks 15 are provided at the lower end of the plastic body 1. The two support blocks 15 are respectively located on both sides of the plastic body 1 and are used to support the PCB board 3 to prevent the PCB board 3 from moving away from the plastic body 1 from below and thus damaging the pins of the terminal 2.
