The first latch 10 is connected to the side of the mounting base 9 facing away from the housing body 1. The first latch 10 is provided with a first slot 13.

[0030] One end of the lock handle 2 is rotatably mounted on the housing body 1, and the other end of the lock handle 2 is provided with a second buckle 3, which engages with the first slot 13.

[0031] Specifically, the mounting base 9 is slidably connected to the housing body 1, and the mounting base 9 is locked onto the housing body 1 by a first locking structure. The first buckle 10 is installed on the mounting base 9, and the first buckle 10 is provided with a first slot 13. The second buckle 3 on the locking handle 2 engages with the first slot 13. This eliminates the need to drill holes in the housing body 1, improving the sealing performance of the plug housing.

[0032] In one embodiment, the mounting base 9 is provided with a groove 17 on the side facing the housing body 1, and the housing body 1 is provided with a slide rail 6, which is slidably connected to the groove 17.

[0033] The first locking structure includes a first stop plate 18 and a second stop plate 7. The first stop plate 18 is disposed on the groove wall of the slide groove 17. The second stop plate 7 is provided at the end of the slide rail away from the shell body 1. The side of the first stop plate 18 facing away from the shell body 1 and the side of the second stop plate 7 facing the shell body 1 are engaged to stop each other.

[0034] Specifically, the shell body 1 has a slide rail 6 on the side facing the mounting base 9, and the mounting base 9 has a slide groove 17 on the side facing the shell body 1. The slide groove 17 is slidably connected to the slide rail 6. A second stop plate 7 is provided at the end of the slide rail 6 away from the shell body 1. The second stop plate 7 is perpendicular to the slide rail 6. A first stop plate 18 is provided on the side wall of the slide groove 17 facing the second stop plate 7. The first stop plate 18 is located at the bottom of the side wall of the slide groove 17 and is perpendicular to the slide rail 6. The side of the first stop plate 18 facing the shell body 1 and the side of the second stop plate 7 facing away from the shell body 1 are in a stop-fitting engagement. During installation, the mounting base 9 is slidably assembled onto the shell body 1 along the extension direction of the slide rail 6. The first stop plate 18 and the second stop plate 7 are in a stop-fitting engagement, thereby limiting the thickness direction of the mounting base 9.

[0035] In one embodiment, the first locking structure further includes a lock hole 23, which is disposed on the side of the mounting base 9 facing the housing body 1. The housing body 1 is provided with a locking pin 33, which is inserted into the lock hole 23.

[0036] Specifically, the mounting base 9 is an elastic element. The mounting base 9 has a locking hole 23 on the side facing the housing body 1. The mounting base 9 is slidably connected to the slide rail 6 from front to back. The locking hole 23 is close to the front end of the slide rail 6. The housing body 1 has a locking pin 33 on the side facing the mounting base 9. The locking pin 33 is close to the front end of the slide rail 6. When the mounting base 9 is slidably connected to the slide rail 6 from front to back, the locking hole 23 will fit onto the locking pin 33, thereby limiting the mounting base 9 in the extension direction of the slide rail 6.

[0037] In one embodiment, the mounting base 9 is provided with a first connecting arm 22, the first connecting arm 22 is located on the side of the mounting base 9 facing the shell body 1, the locking hole 23 is provided on the first connecting arm 22, and the first connecting arm 22 can float towards or away from the shell body 1.

[0038] Specifically, the first connecting arm 22 is located at the front end of the mounting base 9. The first connecting arm 22 is suspended on the mounting base 9, and the lock hole 23 is located on the first connecting arm 22. Since the mounting base 9 is an elastic structure, the first connecting arm 22 can float towards or away from the shell body 1, making it easy to fit the lock hole 23 onto the lock post 33.

[0039] In one embodiment, there are two slide rails 6 and two slide grooves 17, with each slide rail 6 and slide groove 17 corresponding to the other. The first connecting arm 22 is located between the two slide grooves 17, and the locking pin 33 is located between the two slide rails 6.

[0040] Specifically, two slide rails 6 are arranged at intervals, a locking pin 33 is set between the two slide rails 6, two slide grooves 17 are arranged at intervals, and a first connecting arm 22 is set between the two slide grooves 17. The cooperation between the two slide rails 6 and the slide grooves 17 can not only improve the connection strength between the mounting base 9 and the shell body 1, but also straighten the mounting base 9 when installing it, which facilitates the connection between the locking hole 23 and the locking pin 33.

[0041] In one embodiment, the mounting base 9 is provided with a second connecting arm 14, which is located on the side of the mounting base 9 facing away from the shell body 1. The first buckle 10 is connected to the second connecting arm 14, and the second connecting arm 14 can float towards or away from the shell body 1.

[0042] The first buckle 10 includes a mounting part 15, a transition part 12 and a pressing part 11. The transition part 12 is located between the pressing part 11 and the mounting part 15. The mounting part 15 is connected to the second connecting arm 14. The first slot 13 is provided on the transition part 12. The pressing part 11 is engaged with the second buckle 3 on the side facing the shell body 1.

[0043] Specifically, the second connecting arm 14 is disposed at the front end of the mounting base 9 and is suspended on the mounting base 9. The second connecting arm 14 is located above the first connecting arm 22. The second buckle 3 is disposed on the second connecting arm 14. The second connecting arm 14 can float towards or away from the shell body 1, just like the first connecting arm 22. When the locking plate 5 of the lock handle 2 approaches the shell body 1, the locking block 4 of the second buckle 3 will first force the second connecting arm 14 to bend towards the shell body 1. After the locking block 4 of the second buckle 3 passes the pressing part 11 of the first buckle 10, the second connecting arm 14 loses its driving force and restores its deformation, so that the locking block 4 is locked into the first locking groove 13 on the transition part 12, so that the upper side of the locking block 4 and the lower side of the pressing part 11 are stopped and engaged, thereby limiting the locking block 4 and the locking plate 5.

[0044] In one embodiment, the other end of the lock handle 2 is provided with a locking plate 5, and the locking plate 5 has a locking block 4 on the side facing the first buckle 10. The locking block 4 engages with the first locking groove 13, and the locking block 4 forms the second buckle 3.

[0045] It also includes a second locking structure, which is used to lock the end of the card plate 5 away from the first buckle 10 onto the shell body 1.

[0046] Specifically, when the locking plate 5 of the lock handle 2 approaches the housing body 1, the locking block 4 of the second latch 3 will first force the second connecting arm 14 to bend towards the housing body 1. After the locking block 4 of the second latch 3 passes the pressing part 11 of the first latch 10, the second connecting arm 14 loses its driving force and restores its deformation, so that the locking block 4 is engaged in the first slot 13 on the transition part 12, so that the upper side of the locking block 4 and the lower side of the pressing part 11 are stopped and engaged, thereby limiting the front end of the locking block 4 and the locking plate 5. The second locking structure limits the rear end of the locking plate 5, thereby further locking the lock handle 2 onto the latch assembly 8.

[0047] In one embodiment, the mounting base 9 is provided with a socket 16, the opening of the socket 16 being away from the first buckle 10. The second locking structure includes a locking member 24, the locking member 24 including a plug plate 27, an intermediate plate 26 and a stop block 25. The intermediate plate 26 is connected between the plug plate 27 and the stop block 25. The plug plate 27 is movably inserted into the socket 16 through the opening. The side of the stop block 25 facing the shell body 1 is used to stop and cooperate with the side of the buckle 5 facing away from the shell body 1.

[0048] Specifically, the mounting base 9 has an insertion hole 16 between the first connecting arm 22 and the second connecting arm 14. The upper wall of the insertion hole 16 has a first locking hole 19 and a second locking hole 20. The first locking hole 19 and the second locking hole 20 are arranged in opposite directions and spaced back and forth along the extension of the slide rail 6. The insertion plate 27 has a first elastic arm 28. The rear end of the first elastic arm 28 is connected to the insertion plate 27. The front end of the first elastic arm 28 has a first locking block 29. The locking member 24 has a locked position and an open position. In the open position, the first locking block 29 is inserted into the second locking hole 20. When the card block 4 is inserted into the first card slot 13, the insertion plate 27 is pushed forward, so that the locking member 24 moves to the locked position, so that the first locking block 29 is inserted into the first locking hole 19, thereby preventing the insertion plate 27 from falling off the mounting base 9. At this time, the lower side of the stop block 25 blocks the upper side of the card plate 5, thereby limiting the rear end of the card plate 5.

[0049] A third locking hole 21 is provided on the wall of the insertion hole 16 next to the second locking hole 20. The third locking hole 21 is an elongated hole. A second elastic arm 30 is also provided on the insertion plate 27. The rear end of the second elastic arm 30 is connected to the insertion plate 27. A guide slope 31 is provided on the upper side of the rear end of the second elastic arm 30. The guide slope 31 extends from the rear end of the second elastic arm 30 to the insertion plate 27. When the insertion plate 27 is pushed back and forth, the lower edge of the third locking hole 21 will contact the guide slope 31, forcing the insertion plate 27 to bend and deform downward, which facilitates the movement of the first locking block 29 back and forth. A second locking block 32 is provided at the front end of the second elastic arm 30. The second locking block 32 is inserted into the third locking hole 21. The second locking block 32 is used to stop and cooperate with the front end wall of the third locking hole 21.

[0050] The working principle of the plug housing of this utility model embodiment is as follows: When the locking plate 5 of the locking handle 2 approaches the housing body 1, the locking block 4 of the second latch 3 will first force the second connecting arm 14 to bend towards the housing body 1. After the locking block 4 of the second latch 3 passes the pressing part 11 of the first latch 10, the second connecting arm 14 loses driving force and restores its deformation, so that the locking block 4 is locked into the first slot 13 on the transition part 12, so that the upper side of the locking block 4 and the lower side of the pressing part 11 are stopped and cooperated, thereby limiting the front end of the locking block 4 and the locking plate 5. Then, the insert plate 27 is pushed forward, so that the locking member 24 moves to the locking position, so that the first locking block 29 is inserted into the first locking hole 19, thereby preventing the insert plate 27 from falling off the mounting base 9. At this time, the lower side of the baffle and the upper side of the locking plate 5 are stopped, thereby limiting the rear end of the locking plate 5.

[0051] According to the plug housing of this utility model embodiment, compared with the prior art, the mounting base 9 is slidably connected to the housing body 1, the first locking structure locks the mounting base 9 on the housing body 1, and the first buckle 10 is installed on the mounting base 9. It is not necessary to drill holes in the housing body 1, which improves the sealing performance of the plug housing.

[0052] In addition, one embodiment of the present invention also provides a connector, including the plug housing described above.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
