[0043] The terminal receiving portion 10 is configured to receive a mating terminal, which may be a male terminal. The terminal receiving portion 10 has a first sidewall 11 and a second sidewall 12 disposed opposite to each other. The second end of the first sidewall 11 can be connected to the second sidewall 12 through a first connecting wall 13. The left and / or right sides of the first sidewall 11 and the second sidewall 12 can also be connected through a second connecting wall 14, which is disposed close to the second end of the first sidewall 11.

[0044] The first sidewall 11 and the first end of the second sidewall 12 form a receiving port, through which the pin of the mating terminal can be inserted into the terminal receiving part 10.

The second side plate 42 has a second protrusion 421 that engages with the outer surface of the second side wall 12, for example, by welding, bonding, or attaching.

[0047] The locking member 40 ensures that the terminal receiving portion 10 remains stable in a vibration environment. By combining the first protrusion 411 with the outer surface of the first sidewall 11 and the second protrusion 421 with the outer surface of the second sidewall 12, the contact area between the locking member 40 and the terminal receiving portion 10 can be increased, thereby improving connection stability and reliability. Furthermore, the locking member 40 can effectively absorb and disperse impact forces, reduce damage to the internal structure of the terminal receiving portion 10 from external impacts, and improve the overall service life and reliability of the terminal.

[0048] like Figure 5 and Figure 6As shown, in some embodiments, the outer surface of the first sidewall 11 is provided with a plurality of first grooves 111, and the outer surface of the second sidewall 12 is provided with a plurality of second grooves 121; the first grooves 111 are tightly joined with the first protrusion 411; and the second grooves 121 are tightly joined with the second protrusion 421. For example, the first grooves 111 and the first protrusion 411 are tightly joined together by laser welding; and the second grooves 121 and the second protrusion 421 are tightly joined together by laser welding. Of course, the first grooves 111 and the first protrusion 411 are tightly joined together by ultrasonic welding; and the second grooves 121 and the second protrusion 421 are tightly joined together by ultrasonic welding.

Similarly, a plurality of second grooves 121 are spaced apart along the length and / or width direction of the second sidewall 12, and the second protrusions 421 are arranged opposite to the second grooves 121 one by one. The length direction of the first sidewall 11 can be the direction from its first end to its second end, and the width direction of the first sidewall 11 is perpendicular to the length direction. The length direction of the second sidewall 12 can be the direction from its first end to its second end, and the width direction of the second sidewall 12 is perpendicular to the length direction.

[0050] like Figure 5 and Figure 6 As shown, in some embodiments, the number of the first grooves 111 can be four. The shape formed by connecting the four first grooves 111 in a clockwise sequence can be a square or a rectangle to facilitate processing. When any one of the first grooves 111 is disengaged from the first protrusion 411, the remaining first grooves 111 can still be combined with the first protrusion 411 to ensure that the locking member 40 can always function.

[0051] like Figure 5 and Figure 6 As shown, in some embodiments, the number of the second grooves 121 can be four. The shape formed by connecting the four second grooves 121 in a clockwise sequence can be a square or a rectangle to facilitate processing. When any one of the second grooves 121 is disengaged from the second protrusion 421, the remaining second grooves 121 can still be combined with the second protrusion 421 to ensure that the locking member 40 can always function.

[0052] Combination Figures 1 to 4In some embodiments, the orthographic projection shape of the first groove 111 on the first sidewall 11 may be, but is not limited to, a circle, an ellipse, a square or a rectangle, and the shape and size of the first protrusion 411 are adapted to the first groove 111.

[0053] like Figure 5 and Figure 6 As shown, in some embodiments, the orthographic projection shape of the second groove 121 on the second sidewall 12 may be, but is not limited to, a circle, an ellipse, a square or a rectangle, and the shape and size of the second protrusion 421 are adapted to the second groove 121.

[0054] Of course, the shape, number, and position of the first groove 111 and the second groove 121 can be selected according to actual needs, and no specific limitation is made here.

[0055] Combination Figures 1 to 4 In some embodiments, the first sidewall 11 has a first limiting groove 112 and a second limiting groove 113 at both ends along its width direction, and both the first limiting groove 112 and the second limiting groove 113 are located near the first end of the first sidewall 11. The second sidewall 12 has a third limiting groove 122 and a fourth limiting groove 123 at both ends along its width direction, and both the third limiting groove 122 and the fourth limiting groove 123 are located near the first end of the second sidewall 12. The first limiting groove 112 and the third limiting groove 122 are arranged opposite to each other, and the second limiting groove 113 and the fourth limiting groove 123 are arranged opposite to each other.

[0056] The locking member 40 includes a connecting plate 43 that connects the first side plate 41 and the second side plate 42 to their opposite first sides. A portion of the connecting plate 43 is located in the first limiting groove 112 and the third limiting groove 122. A first fastening plate 44 extends from the second side of the first side plate 41 and is located in the second limiting groove 113, with a portion of the first fastening plate 44 situated within the second limiting groove 113.

[0057] The second side plate 42 extends a second fastening plate 45 on its second side. The second fastening plate 45 is located in the fourth limiting groove 123. Part of the structure of the second fastening plate 45 is located in the fourth limiting groove 123, and the second fastening plate 45 is fastened to the first fastening plate 44. This facilitates the assembly of the locking member 40 onto the terminal receiving part 10 by automated equipment. The locking member 40 can be separated by disassembling the first fastening plate 44 and the second fastening plate 45, which facilitates the replacement of the locking member 40 and the maintenance of the terminal.

[0058] Understandably, the first limiting groove 112 and the third limiting groove 122 can serve to position and limit the connecting plate 43. The second limiting groove 113 can serve to position and limit the first fastening plate 44. The fourth limiting groove 123 can serve to position and limit the second fastening plate 45.

[0059] Combination Figures 1 to 4 In some embodiments, the first snap-fit ​​plate 44 is provided with a plurality of first snap-fit ​​portions 441 at one end away from the first side plate 41, and a first snap-fit ​​groove 442 is formed between adjacent first snap-fit ​​portions 441.

The first fastening groove 442 and the second fastening groove 452 are similar to dovetail grooves, and the first fastening portion 441 and the second fastening portion 451 are similar to dovetail structures. This makes the first fastening plate 44 and the second fastening plate 45 more stable and reliable connected after the first fastening portion 441 is engaged with the second fastening groove 452 and after the second fastening portion 451 is engaged with the first fastening groove 442. It can also prevent the first fastening plate 44 and the second fastening plate 45 from separating due to vibration, and can ensure that the locking member 40 can function stably.

Furthermore, there is a gap between the side of the first protrusion 1141 facing the second sidewall 12 and the inner surface of the first sidewall 11, so that the first edge plate 46 will not contact the first spring 20.

[0061] Similarly, the sixth limiting groove 115 penetrates the inner and outer surfaces of the first sidewall 11. A second protrusion 1151 is provided within the sixth limiting groove 115, and a second edge-wrapping plate 47 is provided on the second side of the first sideplate 41. The second edge-wrapping plate 47 is combined with the second protrusion 1151.

Furthermore, a gap is left between the side of the second protrusion 1151 facing the second sidewall 12 and the inner surface of the first sidewall 11, preventing the second edge-wrapping plate 47 from contacting the first spring 20. By providing the first edge-wrapping plate 46 and the second edge-wrapping plate 47, the locking member 40 is less prone to displacement after being assembled onto the terminal receiving part 10, thus improving the assembly stability of the locking member 40.

[0063] The eighth limiting groove 125 penetrates the inner and outer surfaces of the second sidewall 12. A fourth protrusion 1251 is provided within the eighth limiting groove 125. A fourth edge-wrapping plate 49 is provided on the second side of the second sideplate 42, and the fourth edge-wrapping plate 49 is combined with the fourth protrusion 1251. The fourth protrusion 1251 does not protrude from the side of the second sidewall 12, so that after the fourth edge-wrapping plate 49 wraps around the fourth protrusion 1251, the third edge-wrapping plate 48 does not protrude from the side of the second sidewall 12. Furthermore, a gap is left between the side of the fourth protrusion 1251 facing the first sidewall 11 and the inner surface of the second sidewall 12, preventing the fourth edge-wrapping plate 49 from contacting the second spring 30. By providing the third edge-wrapping plate 48 and the fourth edge-wrapping plate 49, the locking member 40 is less prone to displacement after being assembled onto the terminal receiving part 10, thus improving the assembly stability of the locking member 40.
