[0031] [First embodiment]

[0032] like Figure 1-6 The figure shows a double-terminal connector with a locking member provided by the first embodiment of the present invention. Figure 1-3 As shown, it includes terminals 1 arranged symmetrically on both sides, one end of the terminal 1 is connected to the cable 6 and fixed inside the conductor 2, and the conductor 2 is arranged inside the housing 3. A shielding ring 4 is further provided between the outer periphery of the connection position between the cable 6 and the terminal 1 and the inner wall of the conductor 2 to shield unwanted signals through the shielding ring to ensure the stability of the transmitted signal;

[0033] The improvement of this embodiment compared to the prior art is that a locking groove is provided at the bottom of the shell 3, the locking piece 5 is plugged into the locking groove 33, and the locking piece 5 extends between the terminals 1 arranged symmetrically on both sides to achieve axial positioning of the terminal 1 inside the shell 3. By setting the locking piece to a shape that plugs into the locking groove at the bottom of the shell, it is easy to hold to smoothly complete the plugging and unplugging process while ensuring a beautiful appearance.

[0034] like Figure 1 As shown, the shell 3 in this embodiment includes a plug-in portion 31 and a holding portion 32 that are interconnected. The plug-in portion 31 is arranged at the front end of the holding portion 32. The plug-in portion 31 is used to be plugged in with the male / female connector at the other end. The holding portion 32 is convenient for the user to hold to complete the plugging and unplugging action. The outer edge of the plug-in portion 31 is respectively provided with a plug-in locking portion 311 and a plug-in positioning portion 312. The plug-in locking portion 311 is used to plug and lock with the male / female connector at the other end, and the plug-in positioning portion 312 is used to achieve an axial positioning effect when plugging with the male / female connector at the other end. A holding friction pattern 321 is provided on the outer wall of the holding portion 32, thereby further increasing the friction force when the user holds it to maintain a stable hold.

[0035] like Figure 3 As shown, a locking ring 21 corresponding to the locking piece 5 is protruded from the outer edge of the conductor 2 , and the locking ring 21 and the locking piece 5 are matched to achieve axial positioning of the conductor 2 inside the housing 3 .

[0036] like Figure 5-6As shown, the locking member 5 in this embodiment includes a front locking portion 51, the rear side of the front locking portion 51 is connected to a partition 52, the rear side of the partition 52 is connected to the rear locking portion 54 through a connecting plate 53, and the front side of the locking ring 21 abuts against the rear side of the partition 52.

[0037] Among them, a central through hole 531 is provided inside the connecting plate 53, and a central protrusion 331 is extended from the center of the bottom of the shell 3, and the central protrusion 331 can be extended into the interior of the central through hole 531 and positioned with it; and side through holes 532 are provided on both sides of the connecting plate 53, and side protrusions 332 are extended from both sides of the bottom of the shell 3, and the side protrusions 332 can be extended into the interior of the side through holes 532 and positioned with them. Through the positioning cooperation between the central protrusion 331 and the central through hole 531, and the positioning cooperation between the side protrusions 332 and the side through holes 532, the positioning effect of the locking member 5 in the upper and lower directions of the bottom of the shell 3 is achieved.

[0038] like Figure 5-6 As shown, a stop portion 511 is extended from the top center of the front locking portion 51, and a middle column 333 is fixedly provided at the bottom of the shell 3. The rear side of the middle column 333 abuts against the front side of the stop portion 511, and the positioning effect of the locking member 5 in the front and rear directions of the bottom of the shell 3 is achieved through the abutment between the middle column 333 and the stop portion 511.

[0039] In addition, the top of the front locking portion 51 is provided with two sides extending therefrom. The locking tongue portion 512 is made of elastic material and is limitedly matched with the inner wall of the housing 3. Figure 4 As shown, while achieving the positioning effect of the locking member 5 in the left and right directions of the bottom of the shell 3, the locking member is set at the bottom of the shell, and the lock tongue portion of the locking member is set to cooperate with the inner wall of the shell to limit the position, thereby reducing the accidental contact with the lock tongue or the locking portion when plugging and unplugging the connector, reducing the possibility of unexpected loosening of the locking member, further improving the plug-in stability, and ensuring stable signal transmission.

[0040] like Figure 5 As shown, a receiving groove 513 for accommodating the conductor 2 is formed between the stopper 511 and the locking tongue portions 512 on both sides. Side posts 334 are fixedly provided on the bottom of the housing 3. The side posts 334 are located on both sides of the middle post 333. The side posts 334 correspond to the receiving groove 513, and the rear ends of the side posts 334 are located inside the receiving groove 513. Thus, the locking member 5 effectively protects the internal conductor 2 at the bottom. Accordingly, the top of the receiving groove 513, the partition 52, and the rear locking portion 54 are configured in an arc shape corresponding to the outer wall of the conductor 2.

[0041] During the specific assembly of this embodiment, one end of the terminal 1 is first connected to the cable 6, and then the shielding ring 4 is fixed on the periphery of the connection position. The terminal 1, the cable 6 and the shielding ring 4 are then fixed inside the conductor 2. The conductor 2 is then sent from the rear end of the shell 3 to a preset position inside the shell, and the locking member 5 is then installed from the bottom of the shell 3 so that the rear side of the partition 52 of the locking member 5 abuts against the front side of the locking ring 21 of the conductor 2, thereby achieving the axial positioning effect of the conductor 2 inside the shell 3.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
