The cover body 3 is detachably connected to the shell 21, and a second limiting portion 31 is provided on the cover body 3. The second limiting portion 31 is used to abut against the first limiting portion 11 to limit the end of the signal transmission element 1 in the plug-in slot 213, so that the signal transmission element 1 can be firmly in contact with the connecting terminal 22, and the signal transmission element 1 is not easy to be separated from the socket 2, thereby improving the holding force of the signal transmission element 1 in the socket 2.

[0038] It should be noted that, in a related embodiment, the signal transmission element 1 may be a flexible flat cable.

[0039] It should be supplemented that the second limiting portion 31 can be a plastic protrusion structure or a metal puncture protrusion structure.

[0040] In this embodiment, a plurality of first limiting portions 11 are arranged at intervals along the width direction of the signal transmission element 1, and a plurality of second limiting portions 31 are arranged on the cover body 3, and are respectively arranged one-to-one corresponding to each first limiting portion 11. By providing a plurality of first limiting portions 11 and second limiting portions 31, the signal transmission element 1 can be more firmly in contact with the connection terminal 22.

Specifically, the first connection portion 32 is disposed in the insertion slot 213, and the second limit portion 31 is installed on the first connection portion 32, so that the second limit portion 31 can be against the first limit portion 11, so that the signal transmission element 1 can increase the holding force in the housing 21.

[0044] In this embodiment, the cover body 3 also includes a third limiting portion 34, which is connected to the second connecting portion 33, and the shell 21 is provided with a fourth limiting portion 214, which is engaged with the fourth limiting portion 214 to make the cover body 3 and the shell 21 detachably connected.

[0045] Specifically, the third limiting portion 34 and the fourth limiting portion 214 are both limiting protrusions. When the cover 3 is installed on the housing 21, the third limiting portion 34 contacts the fourth limiting portion 214, and the third limiting portion 34 is elastically deformed. The third limiting portion 34 continues to move, and the elastic deformation of the third limiting portion 34 is restored, so that the third limiting portion 34 and the fourth limiting portion 214 can be engaged, so that the cover 3 can be detachably connected to the housing 21.

[0046] In one embodiment, if Figures 1 to 5 As shown, the third limiting portion 34 is provided with a fifth limiting portion 35, and the housing 21 is provided with a sixth limiting portion 215, and the fifth limiting portion 35 is engaged with the sixth limiting portion 215 to prevent the cover 3 from being separated from the housing 21. Specifically, the fifth limiting portion 35 and the sixth limiting portion 215 are both limiting protrusions. After the cover 3 and the housing 21 are installed, when the signal transmission element 1 is connected to the connection terminal 22, the third limiting portion 34 is separated from the fourth limiting portion 214, so that the cover 3 is separated from the housing 21. In order to prevent the cover 3 from being separated from the housing 21, the fifth limiting portion 35 and the sixth limiting portion 215 are provided so that the fifth limiting portion 35 can be engaged with the sixth limiting portion 215, thereby limiting the cover 3 from continuing to be separated from the housing 21. Then, the signal transmission element 1 is inserted into the plug slot 213. After the signal transmission element 1 contacts the connection terminal 22, the cover 3 is pushed so that the third limiting portion 34 and the fourth limiting portion 214 are engaged.

[0049] Specifically, the first locking portion 51 is rotated so that the first locking portion 51 drives the second locking portion 52 to rotate relative to the shell 21, and the second locking portion 52 can abut against the second connecting portion 33, so that the cover body 3 can be stably installed on the shell 21, thereby allowing the signal transmission element 1 to be more firmly in contact with the connecting terminal 22.

[0050] It should be supplemented that the locking member 5 further includes an abutment portion 53, which is connected to the second locking portion 52 and is used to abut against the second connecting portion 33. By providing the abutment portion 53, the abutment portion 53 can provide a support surface for the hand to apply force during the process of rotating and closing the locking member 5.

[0051] In this embodiment, the first locking portion 51 is provided with a locking groove 511, the fixing member 4 is provided with a seventh limiting portion 41, and the groove wall of the locking groove 511 is engaged with the seventh limiting portion 41. Specifically, the seventh limiting portion 41 is a limiting protrusion. When the second locking portion 52 abuts against the first connecting portion 32, the groove wall of the locking groove 511 is engaged with the seventh limiting portion 41, which can enhance the position limitation of the cover body 3 and prevent the cover body 3 from being limited only by the rotating shaft 217 in the locking member 5.

[0052] Further, the second locking portion 52 is formed with an elastic arm 521, and the second connecting portion 33 is provided with an eighth limiting portion 331, and the elastic arm 521 is engaged with the groove wall of the eighth limiting portion 331. Specifically, the eighth limiting portion 331 is a limiting groove. By providing the elastic arm 521, when the second locking portion 52 abuts against the first connecting portion 32, the elastic arm 521 can be engaged with the eighth limiting portion 331, thereby limiting the movement of the second locking portion 52, and the elastic deformation of the elastic arm 521 can generate pressure on the eighth limiting portion 331 toward the housing 21, so that the cover body 3 can be stably installed on the housing 21.

[0053] In one embodiment, if Figure 7 As shown, the cover body 3 is detachably connected to the socket 2 , and the locking member 5 is not required, so that the cover body 3 can be installed on the socket 2 .
