Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector housing and a connector. Background Art

[0002] Connectors are increasingly used in the market and are indispensable in signal transmission technology. However, most current connectors do not have a secondary locking function. Under the influence of unexpected external forces or misoperation, there is often a risk of accidental unlocking, resulting in the risk of accidental separation of the plug and socket, affecting signal transmission. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a connector shell, which realizes secondary locking of the first locking structure by setting a lock catch, thereby avoiding accidental unlocking of the first locking structure and the second locking structure, and ensuring a stable and reliable connection between the first shell and the second shell; the utility model also provides a connector.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A connector housing comprises a first housing and a second housing plugged with the first housing; a first locking structure is arranged on the outer wall of the first housing, and a second locking structure is arranged on the outer wall of the second housing;

[0006] The first locking structure comprises a first locking body, a first locking portion, and an elastic arm, one end of the elastic arm is connected to the outer side wall of the first shell, and the other end is connected to the first locking body, and the first locking portion is arranged on the first locking body; the second locking structure comprises a second locking portion that is locked and matched with the first locking portion to limit the separation of the first shell and the second shell; when the first locking body is pressed and moved, it can drive the first locking portion to separate and unlock from the second locking portion, and drive the elastic arm to deform to provide elastic force for the first locking body and the first locking portion to return to their original positions;

[0007] A lock buckle is movably provided on the first shell or the second shell, and during the movement of the lock buckle, there is a locking working position for limiting the compressive movement of the first locking body and an unlocking working position for allowing the compressive movement of the first locking body.

[0008] With the above structure, after the first shell and the second shell are plugged and matched, the first locking portion will be locked and matched with the second locking portion to limit the separation of the first shell and the second shell; further, the user can operate the lock buckle to move it from the unlocking working position to the locking working position. At this time, when the first locking body is accidentally pressed by an external force, since the lock buckle can limit the movement of the first locking body after being pressed, the first locking portion and the second locking portion cannot be separated and unlocked, further ensuring the accidental separation of the first shell and the second shell;

[0009] If the user wants to separate the first shell from the second shell, the user needs to first operate the lock buckle to move it from the locking working position to the unlocking working position. At this time, the lock buckle releases the restriction on the first locking body, and the user can press the first locking body to move it and drive the first locking part to separate from the second locking part to achieve unlocking. At the same time, the user can separate the first shell from the second shell;

[0010] The elastic arm can enable the first locking part to return to its original position when no other external force acts on the first locking body, thereby ensuring that the first locking part and the second locking part can cooperate more stably and reliably;

[0011] The above structure makes the connection between the first shell and the second shell more stable and reliable, and the locking and unlocking operations are very convenient, and the product structure is simple.

[0012] Furthermore, the first locking body has a lock fitting portion, and when the first locking body is pressed and moved, the lock fitting portion moves toward the outer side wall of the first housing;

[0013] The lock buckle comprises a lock buckle part; the lock buckle is slidably arranged on the first shell, and when the lock buckle slides to the locking working position, the lock buckle part is located below the lock buckle matching part, and the distance from one end of the lock buckle part facing the lock buckle matching part to the outer side wall of the first shell is greater than the distance from the side of the lock buckle matching part facing the outer side wall of the first shell to the outer side wall of the first shell when the first locking body is pressed and the first locking part is completely separated from the second locking part;

[0014] When the lock catch slides to the unlocking working position, the lock catch portion is away from the lock catch matching portion.

[0015] With the above structure, when the user operates to slide the lock buckle to make it slide from the unlocking working position to the locking working position, the lock buckle part is located below the lock buckle matching part of the first locking body, and due to the distance limit from the end of the lock buckle part facing the lock buckle matching part to the outer side wall of the first shell, when the first locking body is pressed down by external force, the first locking body moves so that the lock buckle matching part abuts against the top of the lock buckle part to limit the lock buckle matching part from continuing to move in the side direction, that is, limiting the first locking body from continuing to move in the unlocking direction, and at this time, the first locking part and the second locking part maintain a state of contacting and locking with each other;

[0016] When the user operates to slide the lock from the locking working position to the unlocking working position, the lock portion moves away from the lock fitting portion, and the lock portion releases the restriction on the lock fitting portion, that is, releases the restriction on the first locking body.

[0017] Further, the lock buckle is slidably arranged on the first housing;

[0018] A first limiting protrusion is provided on one side of the lock buckle facing the first housing, and a second limiting protrusion is provided on the outer side wall of the first housing so as to protrude in the sliding track of the first limiting protrusion;

[0019] When the lock buckle slides from the unlocking working position to the locking working position, the first limiting protrusion side wall of the first limiting protrusion abuts against the second limiting protrusion side wall of the second limiting protrusion to limit the lock buckle from sliding from the unlocking working position to the locking working position, and at least one of the first limiting protrusion side wall and the second limiting protrusion side wall is configured to guide the first limiting protrusion to cross the first crossing guide slope of the second limiting protrusion when an external operating force acts on the lock buckle;

[0020] During the process of the lock buckle sliding from the locked working position to the unlocked working position, the third limiting protrusion side wall of the first limiting protrusion will abut against the fourth limiting protrusion side wall of the second limiting protrusion to limit the lock buckle from sliding from the locked working position to the unlocked working position, and at least one of the third limiting protrusion side wall and the fourth limiting protrusion side wall is configured to guide the first limiting protrusion to cross the second crossing guide slope of the second limiting protrusion when an external operating force acts on the lock buckle.

[0021] When the user acts on the lock buckle to move it from the unlocking working position to the locking working position, the first limiting protrusion side wall of the first limiting protrusion will abut against the second limiting protrusion side wall of the second limiting protrusion. If the user continues to act on the lock buckle, due to the setting of the first crossing guide inclined surface, the first limiting protrusion can pass over the second limiting protrusion. During this process, the user's operating feel will change and a sound similar to "click" will be emitted to remind the user that the lock buckle has moved to the locking working position; and without the action of external force, the third limiting protrusion side wall of the first limiting protrusion cooperates with the fourth limiting protrusion side wall of the second limiting protrusion to limit the lock buckle from sliding from the locking working position to the unlocking working position, that is, to maintain the lock buckle in the locking working position to avoid accidental unlocking of the lock buckle.

[0022] When the user acts on the lock buckle to move it from the locked working position to the unlocked working position, the third limiting protrusion side wall of the first limiting protrusion will abut against the fourth limiting protrusion side wall of the second limiting protrusion. If the user continues to act on the lock buckle, due to the setting of the second crossing guide inclined surface, the first limiting protrusion can cross the second limiting protrusion. During this process, the user's operating feel will change and a sound similar to "click" will be emitted to remind the user that the lock buckle has moved to the unlocked working position; and without the action of external force, the first limiting protrusion side wall of the first limiting protrusion cooperates with the second limiting protrusion side wall of the second limiting protrusion to limit the lock buckle from sliding from the unlocked working position to the locked working position, that is, to maintain the lock buckle in the unlocked working position to avoid accidental locking of the lock buckle;

[0023] The above structure can ensure the stability and reliability of the product; specifically, the first limiting protrusion side wall and the second limiting protrusion side wall are both configured as the first crossing guide slope; the third limiting protrusion side wall and the fourth limiting protrusion side wall are both configured as the second crossing guide slope.

[0024] Furthermore, a slide rail groove for guiding the lock buckle to slide, and the slide rail groove extends in a direction close to and away from the first locking body, and one end of the slide rail groove away from the first locking body extends outward to form a slide rail groove opening on the first shell, and a first blocking protrusion is provided on the side of the lock buckle facing the slide rail groove, and correspondingly, the slide rail groove protrusion is provided with a second blocking protrusion, when the lock buckle is installed to the slide rail groove, the side of the first blocking protrusion facing the slide rail groove opening is formed as a first blocking surface, and the side of the second blocking protrusion away from the slide rail groove opening is formed as a second blocking surface, the first blocking surface and the second blocking surface cooperate and abut against each other to limit the movement of the lock buckle toward the slide rail groove opening, and when the first blocking surface abuts against the second blocking surface, the lock buckle is located in the unlocking working position.

[0025] With the above structure, the arrangement of the first blocking protrusion and the second blocking protrusion can limit the sliding range of the lock buckle; when the lock buckle moves toward the unlocking working position side, the first blocking surface of the first blocking protrusion will eventually contact the second blocking surface of the second blocking protrusion to limit the lock buckle from further moving in the side direction, thereby preventing the lock buckle from escaping from the slide rail groove through the slide rail groove opening;

[0026] Specifically, the first blocking protrusion is arranged on the side of the lock buckle facing the bottom surface of the slide rail groove, and the first blocking surface is perpendicular to the end surface on which the blocking protrusion is arranged; correspondingly, the second blocking protrusion is arranged on the bottom surface of the slide rail groove, and the second blocking surface is perpendicular to the bottom surface of the slide rail groove.

[0027] Furthermore, the side wall of the slide rail groove is recessed inward to form a slide groove, and correspondingly, the lock buckle protrudes toward the side wall of the slide groove to form a slider protrusion matching the slide groove; the side of the slide groove away from the opening of the slide rail groove is formed as a slide groove limiting end, and when the slider protrusion abuts against the slide groove limiting end, the lock buckle is located in the locking working position.

[0028] With the above structure, the arrangement of the slide groove and the slider protrusion can make the sliding of the lock buckle more stable, and the slide groove can limit the sliding range of the lock buckle. When the lock buckle slides toward the unlocking working position, the slider protrusion will eventually abut against the limiting end of the slide groove to limit the lock buckle from further moving toward the side direction.

[0029] Specifically, the side walls on both sides of the slide rail groove are provided with the slide grooves, and correspondingly, the two sides of the lock buckle are also provided with the slider protrusions.

[0030] Further, the side of the first blocking protrusion opposite to the first blocking surface is formed as a first mounting mating surface, the side of the second blocking protrusion facing the opening of the slide rail groove is formed as a second mounting mating surface, and at least one of the first mounting mating surface and the second mounting mating surface is configured to guide the first blocking protrusion to cross the mounting guide inclined surface of the second blocking protrusion when an external operating force acts on the lock.

[0031] With the above structure, when the lock buckle is installed into the slide rail groove through the slide rail groove opening, the first installation matching surface of the first blocking protrusion will abut against the second installation matching surface of the second blocking protrusion. Further, under the action of external force, due to the setting of the installation guide inclined surface, the first blocking protrusion can pass over the second blocking protrusion, thereby realizing the installation of the lock buckle.

[0032] Specifically, the first mounting mating surface and the second mounting mating surface are both configured as the mounting guide inclined surfaces;

[0033] Of course, when installing the lock buckle, the first limiting protrusion on the lock buckle will also contact the second blocking protrusion, so that the first limiting protrusion side wall on the first limiting protrusion is configured as the first crossing guide slope and / or the second installation mating surface is configured as the installation guide slope, so as to guide the first limiting protrusion to cross the second blocking protrusion when an external force acts on the lock buckle.

[0034] Furthermore, the lock is provided with a lock operating portion for the user to apply force to the lock, and along the sliding direction of the lock, side walls of the lock operating portion are formed as lock operating surfaces.

[0035] With the above structure, the arrangement of the lock operating portion can facilitate the user to apply force to the lock.

[0036] Furthermore, the lock operation surface is an inclined surface inclined toward the axis side of the lock operation portion, and anti-slip corrugations are arranged on the lock operation surface.

[0037] The above structure makes it easier for the user to apply force to the lock buckle, and the provision of the anti-slip corrugations greatly increases the friction between the human hand and the lock buckle operating surface, further facilitating the user to apply force to the lock buckle.

[0038] Further, one end of the first shell that is plugged into and matched with the second shell is formed as a first plug-in matching end;

[0039] The first locking body includes a locking connection portion arranged close to the first plug-in mating end, a pressing portion arranged away from the first plug-in mating end, and an intermediate connection portion connected between the locking connection portion and the pressing portion, the elastic arm is connected between the intermediate connection portion and the outer side wall of the first shell, and the first locking portion is arranged on the locking connection portion.

[0040] With the above structure, when the pressing portion is pressed, the pressing portion moves toward the first housing side, and the locking connection portion moves in a direction away from the first housing, in a state where one end is pressed down and the other end is tilted up, thereby driving the first locking portion to separate and unlock from the second locking portion;

[0041] Specifically, the pressing portion is formed as a lock fitting portion; anti-slip corrugations are provided on a side of the pressing portion away from the first shell, and the provision of the anti-slip corrugations greatly increases the friction between a human hand and the pressing portion, making it easier for a user to apply force to the pressing portion.

[0042] Furthermore, the elastic arm includes a first elastic arm section and a second elastic arm section, one end of the first elastic arm section is connected to the middle connecting part, and the other end is connected to one end of the second elastic arm section, the other end of the second elastic arm section is connected to the outer side wall of the first shell, and the first elastic arm section and the second elastic arm section are extended in different directions.

[0043] By adopting the above structure, the pressing part is pressed to drive the middle connecting part to move, thereby driving the first elastic arm section and the second elastic arm section to bend and deform, generating elastic force. When the pressing part is released, under the action of the elastic force, the first locking body and the first locking part can return to their positions; specifically, two elastic arms are provided, which are respectively located on both sides of the first locking body. The above structure can provide sufficient elastic force.

[0044] Further, the intermediate connection part includes a first intermediate connection part and a second intermediate connection part, one end of the first intermediate connection part is connected to the pressing part, and the other end is connected to one end of the second intermediate connection part, the other end of the second intermediate connection part is connected to the locking connection part, and both sides of the first intermediate connection part protrude from the second intermediate connection part to form an elastic arm connection part;

[0045] One end of the first elastic arm section is connected to a side of the elastic arm connecting portion facing the second middle connecting portion, and a gap is provided between the first elastic arm section and the second middle connecting portion.

[0046] The above structure makes the arrangement and structure of the elastic arm more reasonable, and is more conducive to the deformation of the elastic arm when the pressing portion is pressed.

[0047] Furthermore, an extending direction of the first elastic arm section is the same as or substantially the same as an extending direction of the pressing portion, and an extending direction of the second elastic arm section is perpendicular or substantially perpendicular to an extending direction of the first elastic arm section.

[0048] The above structure makes the structure of the elastic arm more reasonable, and is more conducive to the deformation of the elastic arm when the pressing portion is pressed.

[0049] Furthermore, the first shell is provided with baffles on both sides of the first locking body, and the baffles are extended along the length direction of the first locking body.

[0050] With the above structure, the setting of the baffle can effectively prevent the first locking body from being accidentally pressed and unlocked due to impact by foreign objects, and the above structure further ensures the reliability of the product.

[0051] Furthermore, the first locking portion is formed as a hook structure disposed toward the first shell side; correspondingly, the second locking portion is formed as an inverted structure disposed away from the second shell side.

[0052] With the above structure, the hook structure and the barb structure realize locking and unlocking of the first locking portion and the second locking portion; of course, in some embodiments, the first locking portion is formed as a buckle structure, and the second locking portion is formed as a slot structure;

[0053] Specifically, two second locking structures are provided and arranged side by side on the second shell, and the second locking parts of the two second locking structures are locked and cooperated with the first locking part of one first locking structure; the above structure makes the locking of the first locking structure and the second locking structure more stable and reliable.

[0054] Further, one end of the first shell that is plugged into and matched with the second shell is formed as a first plugged into and matched end, and one end of the second shell that is plugged into and matched with the first shell is formed as a second plugged into and matched end;

[0055] The first plug-in mating end includes a first plug-in surrounding wall in an enclosed shape, the second plug-in mating end includes a second plug-in surrounding wall in an enclosed shape, and a second plug-in mating portion arranged in the second plug-in surrounding wall, and a plug-in accommodating groove that matches the second plug-in surrounding wall to accommodate the second plug-in surrounding wall is formed between the outer wall of the second plug-in mating portion and the inner wall of the second plug-in surrounding wall.

[0056] With the above structure, the first plug-in surrounding wall can be inserted into the plug-in receiving groove to achieve plug-in fit between the first shell and the second shell.

[0057] Further, at least one group of opposite inner walls in the first plug-in enclosure is provided with fool-proof convex ribs, and the number of fool-proof convex ribs provided on one side wall of each group of the first plug-in enclosure provided with the fool-proof convex ribs is not equal to the number of fool-proof convex ribs provided on another side wall;

[0058] Correspondingly, when the first plug-in enclosure is inserted into the plug-in receiving groove, a matching number of anti-foolproof grooves for accommodating the anti-foolproof ribs are provided on the outer wall of the second plug-in mating portion that is opposite to the inner wall of the first plug-in enclosure with the anti-foolproof ribs.

[0059] With the above structure, the fool-proof convex rib and the fool-proof groove are arranged so that the first plug-in surrounding wall can be inserted into the plug-in receiving groove only when the two are completely matched, thereby preventing the user from inserting the plug-in reversely.

[0060] Furthermore, a plug-in seal is provided on the outer side wall of the first plug-in enclosure, and when the first plug-in enclosure is inserted into the plug-in receiving groove, the plug-in seal is sealed and matched with the inner wall of the second plug-in enclosure.

[0061] With the above structure, the provision of the plug-in seal can effectively prevent liquid from entering.

[0062] Further, the first shell includes a first inner shell, a first outer shell, and an end seal, the first outer shell is sleeved outside the first inner shell, and one end of the first inner shell extends beyond the first outer shell to form a first plug-in mating end that is plug-in mating with the second shell, the other end of the first outer shell extends beyond the other end of the first inner shell to form an end seal accommodating groove, the end seal is installed in the end seal accommodating groove, and is sealed and mated with the inner wall of the end seal accommodating groove.

[0064] Further, an internal seal is provided on the first inner shell, and when the first inner shell is installed in the first outer shell, the internal seal is in sealing contact with the inner wall of the first outer shell.

[0065] The above structure is adopted to ensure the sealing performance of the first shell itself.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0089] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0090] See also Figures 1 to 7 The utility model provides a connector housing, comprising a first housing 1 and a second housing 2 plugged with the first housing 1; a first locking structure 3 is provided on the outer wall of the first housing 1, and a second locking structure 4 is provided on the outer wall of the second housing 2;

[0091] The first locking structure 3 includes a first locking body 301, a first locking portion 302, and an elastic arm 303, one end of the elastic arm 303 is connected to the outer wall of the first shell 1, and the other end is connected to the first locking body 301, and the first locking portion 302 is arranged on the first locking body 301; the second locking structure 4 includes a second locking portion 401 that is locked and matched with the first locking portion 302 to limit the separation of the first shell 1 and the second shell 2; when the first locking body 301 is pressed and moved, it can drive the first locking portion 302 to separate and unlock from the second locking portion 401, and drive the elastic arm 303 to deform to provide elastic force for the first locking body 301 and the first locking portion 302 to return to their original positions;

[0092] A lock buckle 5 is movably provided on the first shell 1 or the second shell 2 , and the lock buckle 5 has a locking working position for limiting the compressive movement of the first locking body 301 and an unlocking working position for allowing the compressive movement of the first locking body 301 during movement.

[0093] With the above structure, after the first shell 1 and the second shell 2 are plugged and matched, the first locking portion 302 will be locked and matched with the second locking portion 401 to limit the separation of the first shell 1 and the second shell 2; further, the user can operate the lock buckle 5 to move it from the unlocking working position to the locking working position. At this time, when the first locking body 301 is accidentally pressed by an external force, since the lock buckle 5 can limit the movement of the first locking body 301 after being pressed, the first locking portion 302 and the second locking portion 401 cannot be separated and unlocked, further ensuring the accidental separation of the first shell 1 and the second shell 2;

[0094] If the user wants to separate the first shell 1 from the second shell 2, the user needs to first operate the lock buckle 5 to move it from the locking working position to the unlocking working position. At this time, the lock buckle 5 releases the restriction on the first locking body 301. The user can press the first locking body 301 to move it and drive the first locking part 302 to separate from the second locking part 401 to achieve unlocking. At the same time, the user can separate the first shell 1 from the second shell 2.

[0095] The elastic arm 303 can enable the first locking portion 302 to return to its original position when no other external force acts on the first locking body 301, thereby ensuring that it can cooperate with the second locking portion 401 more stably and reliably;

[0096] The above structure makes the connection between the first shell 1 and the second shell 2 more stable and reliable, and the locking and unlocking operations are very convenient, and the product structure is simple.

[0097] Furthermore, the first locking body 301 has a lock fitting portion 3011, and when the first locking body 301 is pressed, the lock fitting portion 3011 moves toward the outer side wall of the first housing 1;

[0098] The lock buckle 5 comprises a lock buckle part 501; the lock buckle 5 is slidably arranged on the first shell 1, and when the lock buckle 5 slides to the locking working position, the lock buckle part 501 is located below the lock buckle matching part 3011, and the distance from one end of the lock buckle part 501 facing the lock buckle matching part 3011 to the outer side wall of the first shell 1 is greater than the distance from one side of the lock buckle matching part 3011 facing the outer side wall of the first shell 1 to the outer side wall of the first shell 1 when the first locking body 301 is pressed and the first locking part 302 is completely separated from the second locking part 401;

[0099] When the lock buckle 5 slides to the unlocking working position, the lock buckle portion 501 is away from the lock buckle matching portion 3011 .

[0100] With the above structure, when the user operates to slide the lock buckle 5 to make it slide from the unlocking working position to the locking working position, the lock buckle portion 501 is located below the lock buckle matching portion 3011 of the first locking body 301, and due to the distance limit between the end of the lock buckle portion 501 facing the lock buckle matching portion 3011 and the outer side wall of the first shell 1, when the first locking body 301 is pressed down by an external force, the movement of the first locking body 301 will make the lock buckle matching portion 3011 abut against the top of the lock buckle portion 501 to limit the lock buckle matching portion 3011 from continuing to move in the side direction, that is, limiting the first locking body 301 from continuing to move in the unlocking direction, and at this time, the first locking portion 302 and the second locking portion 401 maintain a state of mutual contact and locking cooperation;

[0101] When the user operates to slide the lock 5 from the locking working position to the unlocking working position, the lock portion 501 moves away from the lock fitting portion 3011, and the lock portion 501 releases the restriction on the lock fitting portion 3011, that is, releases the restriction on the first locking body 301.

[0102] Furthermore, the lock buckle 5 is slidably disposed on the first housing 1;

[0103] The lock buckle 5 is provided with a first limiting protrusion 502 on one side facing the first housing 1, and the outer side wall of the first housing 1 is provided with a second limiting protrusion 101 protruding in the sliding track of the first limiting protrusion 502;

[0104] During the process of the lock buckle 5 sliding from the unlocking working position to the locking working position, the first limiting protrusion side wall 5021 of the first limiting protrusion 502 abuts against the second limiting protrusion side wall 1011 of the second limiting protrusion 101 to limit the lock buckle 5 from sliding from the unlocking working position to the locking working position, and at least one of the first limiting protrusion side wall 5021 and the second limiting protrusion side wall 1011 is configured to guide the first limiting protrusion 502 to cross the first crossing guide inclined surface 6 of the second limiting protrusion 101 when an external operating force acts on the lock buckle 5;

[0105] During the process of the lock buckle 5 sliding from the locked working position to the unlocked working position, the third limiting protrusion side wall 5022 of the first limiting protrusion 502 will abut against the fourth limiting protrusion side wall 1012 of the second limiting protrusion 101 to limit the lock buckle 5 from sliding from the locked working position to the unlocked working position, and at least one of the third limiting protrusion side wall 5022 and the fourth limiting protrusion side wall 1012 is configured to guide the first limiting protrusion 502 to cross the second crossing guide slope 7 of the second limiting protrusion 101 when an external operating force acts on the lock buckle 5.

[0106] With the above structure, when the user acts on the lock buckle 5 to move it from the unlocking working position to the locking working position, the first limiting protrusion side wall 5021 of the first limiting protrusion 502 will abut against the second limiting protrusion side wall 1011 of the second limiting protrusion 101. If the user continues to act on the lock buckle 5, due to the setting of the first crossing guide inclined surface 6, the first limiting protrusion 502 can cross the second limiting protrusion 101. During this process, the user's operating feel will change, and a sound similar to "click" will be emitted to remind the user that the lock buckle 5 has moved to the locking working position; and without the action of external force, the third limiting protrusion side wall 5022 of the first limiting protrusion 502 cooperates with the fourth limiting protrusion side wall 1012 of the second limiting protrusion 101 to limit the lock buckle 5 from sliding from the locking working position to the unlocking working position, that is, to maintain the lock buckle 5 in the locking working position to avoid accidental unlocking of the lock buckle 5;

[0107] When the user acts on the lock buckle 5 to move it from the locked working position to the unlocked working position, the third limiting protrusion side wall 5022 of the first limiting protrusion 502 will abut against the fourth limiting protrusion side wall 1012 of the second limiting protrusion 101. If the user continues to act on the lock buckle 5, due to the setting of the second crossing guide inclined surface 7, the first limiting protrusion 502 can cross the second limiting protrusion 101. During this process, the user's operating feel will change, and a sound similar to "click" will be emitted to remind the user that the lock buckle 5 has moved to the unlocked working position; and without the action of external force, the first limiting protrusion side wall 5021 of the first limiting protrusion 502 cooperates with the second limiting protrusion side wall 1011 of the second limiting protrusion 101 to limit the lock buckle 5 from sliding from the unlocked working position to the locked working position, that is, to maintain the lock buckle 5 in the unlocked working position to avoid accidental locking of the lock buckle 5;

[0108] The above structure can ensure the stability and reliability of the product; specifically, the first limiting protrusion side wall 5021 and the second limiting protrusion side wall 1011 are both configured as the first crossing guide slope 6; the third limiting protrusion side wall 5022 and the fourth limiting protrusion side wall 1012 are both configured as the second crossing guide slope 7.

[0109] Further, the first housing 1 is provided with a slide rail groove 103 for guiding the lock buckle 5 to slide, and the slide rail groove 103 is extended in a direction close to and away from the first locking body 301, and one end of the slide rail groove 103 away from the first locking body 301 extends outward to form a slide rail groove opening 1031 on the first housing 1, and the lock buckle 5 is provided with a first blocking protrusion 503 on one side facing the slide rail groove 103, and correspondingly, the slide rail groove 103 is convexly provided with a second blocking protrusion 1032, and the lock buckle 5 is installed to the slide rail groove 1 03 state, the side of the first blocking protrusion 503 facing the slide rail groove opening 1031 is formed as a first blocking surface 5031, and the side of the second blocking protrusion 1032 away from the slide rail groove opening 1031 is formed as a second blocking surface 1032a, the first blocking surface 5031 and the second blocking surface 1032a cooperate and abut against each other to limit the movement of the lock buckle 5 toward the slide rail groove opening 1031, and when the first blocking surface 5031 abuts against the second blocking surface 1032a, the lock buckle 5 is located in the unlocking working position.

[0110] With the above structure, the arrangement of the first blocking protrusion 503 and the second blocking protrusion 1032 can limit the sliding range of the lock buckle 5; when the lock buckle 5 moves toward the unlocking working position, the first blocking surface 5031 of the first blocking protrusion 503 will eventually contact the second blocking surface 1032a of the second blocking protrusion 1032, so as to limit the lock buckle 5 from further moving in the side direction, and prevent the lock buckle 5 from escaping from the slide rail groove 103 through the slide rail groove opening 1031;

[0111] Specifically, the first blocking protrusion 503 is arranged on the side of the lock buckle 5 facing the bottom surface of the slide rail groove 103, and the first blocking surface 5031 is perpendicular to the end surface on which the blocking protrusion is arranged; correspondingly, the second blocking protrusion 1032 is arranged on the bottom surface of the slide rail groove 103, and the second blocking surface 1032a is perpendicular to the bottom surface of the slide rail groove 103.

[0112] Furthermore, the side wall of the slide groove 103 is recessed inward to form a slide groove 1033, and correspondingly, the lock buckle 5 protrudes toward the side wall of the slide groove 1033 to form a slider protrusion 504 matching the slide groove 1033; the side of the slide groove 1033 away from the slide groove opening 1031 is formed as a slide groove limiting end 1033a, and when the slider protrusion 504 abuts against the slide groove limiting end 1033a, the lock buckle 5 is located in the locking working position.

[0113] With the above structure, the arrangement of the slide groove 1033 and the slider protrusion 504 can make the sliding of the lock buckle 5 more stable, and the slide groove 1033 can limit the sliding range of the lock buckle 5. When the lock buckle 5 slides toward the unlocking working position, the slider protrusion 504 will eventually abut against the slide groove limiting end 1033a to limit the lock buckle 5 from further moving toward the side direction.

[0114] Specifically, the side walls on both sides of the slide rail groove 103 are both provided with the slide grooves 1033 , and correspondingly, the two sides of the lock buckle 5 are also both provided with the slider protrusions 504 .

[0115] Further, the side of the first blocking protrusion 503 opposite to the first blocking surface 5031 is formed as a first installation mating surface 5032, and the side of the second blocking protrusion 1032 facing the slide rail groove opening 1031 is formed as a second installation mating surface 1032b, and at least one of the first installation mating surface 5032 and the second installation mating surface 1032b is configured to guide the first blocking protrusion 503 to cross the installation guide inclined surface 8 of the second blocking protrusion 1032 when an external operating force acts on the lock buckle 5.

[0116] With the above structure, when the lock buckle 5 is installed into the slide rail groove 103 through the slide rail groove opening 1031, the first installation matching surface 5032 of the first blocking protrusion 503 will abut against the second installation matching surface 1032b of the second blocking protrusion 1032. Further, under the action of external force, due to the setting of the installation guide inclined surface 8, the first blocking protrusion 503 can pass over the second blocking protrusion 1032, thereby realizing the installation of the lock buckle 5.

[0117] Specifically, the first mounting mating surface 5032 and the second mounting mating surface 1032b are both configured as the mounting guide inclined surface 8;

[0118] Of course, when installing the lock buckle 5, the first limiting protrusion 502 on the lock buckle 5 will also contact the second blocking protrusion 1032, so that the first limiting protrusion side wall 5021 on the first limiting protrusion 502 is configured as the first crossing guide bevel 6 and / or the second installation mating surface 1032b is configured as the installation guide bevel 8, so as to guide the first limiting protrusion 502 to cross the second blocking protrusion 1032 when an external force acts on the lock buckle 5.

[0119] Furthermore, the lock buckle 5 is provided with a lock buckle operating portion 505 for the user to apply force to the lock buckle 5 , and along the sliding direction of the lock buckle 5 , the side walls of the lock buckle operating portion 505 form lock buckle operating surfaces 5051 .

[0120] With the above structure, the arrangement of the lock operating portion 505 can facilitate the user to apply force to the lock 5 .

[0121] Furthermore, the locking operation surface 5051 is an inclined surface inclined toward the axis side of the locking operation part 505 , and anti-slip corrugations 9 are provided on the locking operation surface 5051 .

[0122] The above structure makes it easier for the user to apply force to the lock buckle 5 , and the provision of the anti-slip corrugations 9 greatly increases the friction between the human hand and the lock buckle operating surface 5051 , further facilitating the user to apply force to the lock buckle 5 .

[0123] Further, one end of the first shell 1 that is plugged and matched with the second shell 2 is formed as a first plug-matching end 102;

[0124] The first locking body 301 includes a locking connection portion 3012 arranged close to the first plug-in mating end 102, a pressing portion 3013 arranged away from the first plug-in mating end 102, and an intermediate connection portion 3014 connected between the locking connection portion 3012 and the pressing portion 3013, the elastic arm 303 is connected between the intermediate connection portion 3014 and the outer wall of the first shell 1, and the first locking portion 302 is arranged on the locking connection portion 3012.

[0125] With the above structure, when the pressing portion 3013 is pressed, the pressing portion 3013 moves toward the first housing 1, and the locking connection portion 3012 moves away from the first housing 1, with one end pressed down and the other end lifted up, thereby driving the first locking portion 302 to separate and unlock from the second locking portion 401;

[0126] Specifically, the pressing portion 3013 is formed as a lock fitting portion 3011; an anti-slip corrugation 9 is provided on the side of the pressing portion 3013 away from the first shell 1. The provision of the anti-slip corrugation 9 greatly increases the friction between the human hand and the pressing portion 3013, making it convenient for the user to apply force to the pressing portion 3013.

[0127] Furthermore, the elastic arm 303 includes a first elastic arm segment 3031 and a second elastic arm segment 3032, one end of the first elastic arm segment 3031 is connected to the middle connecting portion 3014, and the other end is connected to one end of the second elastic arm segment 3032, the other end of the second elastic arm segment 3032 is connected to the outer wall of the first shell 1, and the first elastic arm segment 3031 and the second elastic arm segment 3032 are extended in different directions.

[0128] By adopting the above structure, the pressing portion 3013 is pressed, which can drive the middle connecting portion 3014 to move, and then drive the first elastic arm section 3031 and the second elastic arm section 3032 to bend and deform, thereby generating an elastic force. When the pressing portion 3013 is released, under the action of the elastic force, the first locking body 301 and the first locking portion 302 can return to their original positions; specifically, two elastic arms 303 are provided, which are respectively located on both sides of the first locking body 301. The above structure can provide sufficient elastic force.

[0129] Further, the intermediate connection part 3014 includes a first intermediate connection part 3014a and a second intermediate connection part 3014b, one end of the first intermediate connection part 3014a is connected to the pressing part 3013, and the other end is connected to one end of the second intermediate connection part 3014b, the other end of the second intermediate connection part 3014b is connected to the locking connection part 3012, and both sides of the first intermediate connection part 3014a protrude from the second intermediate connection part 3014b to form a connection part of the elastic arm 303;

[0130] One end of the first elastic arm section 3031 is connected to a side of the elastic arm 303 connecting portion facing the second middle connecting portion 3014b, and a gap is formed between the first elastic arm section 3031 and the second middle connecting portion 3014b.

[0131] The above structure makes the arrangement and structure of the elastic arm 303 more reasonable, and is more conducive to the deformation of the elastic arm 303 when the pressing portion 3013 is pressed.

[0132] Furthermore, an extending direction of the first elastic arm section 3031 is the same as or substantially the same as an extending direction of the pressing portion 3013 , and an extending direction of the second elastic arm section 3032 is perpendicular or substantially perpendicular to an extending direction of the first elastic arm section 3031 .

[0133] The above structure makes the structure of the elastic arm 303 more reasonable, and is more conducive to the deformation of the elastic arm 303 when the pressing portion 3013 is pressed.

[0134] Furthermore, the first housing 1 is provided with baffles 10 on both sides of the first locking body 301 , and the baffles 10 are extended along the length direction of the first locking body 301 .

[0135] With the above structure, the setting of the baffle 10 can effectively prevent the first locking body 301 from being accidentally pressed and unlocked by being hit by foreign objects, and the above structure further ensures the reliability of the product.

[0136] Furthermore, the first locking portion 302 is formed as a hook structure disposed toward the first shell 1 side; correspondingly, the second locking portion 401 is formed as an inverted structure disposed away from the second shell 2 side.

[0137] With the above structure, the hook structure and the barb structure realize locking and unlocking of the first locking portion 302 and the second locking portion 401; of course, in some embodiments, the first locking portion 302 is formed as a buckle structure, and the second locking portion 401 is formed as a slot structure;

[0138] Specifically, two second locking structures 4 are provided and arranged side by side on the second shell 2, and the second locking parts 401 of the two second locking structures 4 are locked and matched with the first locking part 302 of one first locking structure 3; the above structure makes the locking of the first locking structure 3 and the second locking structure 4 more stable and reliable.

[0139] Further, one end of the first shell 1 that is plugged into and matched with the second shell 2 is formed as a first plugged into and matched end 102, and one end of the second shell 2 that is plugged into and matched with the first shell 1 is formed as a second plugged into and matched end 201;

[0140] The first plug-in mating end 102 includes a first plug-in enclosure 1021 in an enclosed shape, the second plug-in mating end 201 includes a second plug-in enclosure 2011 in an enclosed shape, and a second plug-in mating portion 2012 arranged in the second plug-in enclosure 2011, and a plug-in accommodating groove 2013 is formed between the outer wall of the second plug-in enclosure 2012 and the inner wall of the second plug-in enclosure 2011 to match the second plug-in enclosure 2011 to accommodate the second plug-in enclosure 2011.

[0141] With the above structure, the first plug-in surrounding wall 1021 can be inserted into the plug-in receiving groove 2013 to achieve plug-in fit between the first shell 1 and the second shell 2 .

[0142] Further, at least one group of opposite inner walls of the first plug-in enclosure 1021 is provided with fool-proof convex ribs 1022, and the number of fool-proof convex ribs 1022 provided on one side wall of each group of the first plug-in enclosure 1021 provided with the fool-proof convex ribs 1022 is not equal to the number of fool-proof convex ribs 1022 provided on another side wall;

[0143] Correspondingly, when the first plug-in wall 1021 is inserted into the plug-in receiving groove 2013, a matching number of anti-foolproof grooves 2014 for accommodating the anti-foolproof rib 1022 are provided on the outer wall of the second plug-in mating part 2012 which is opposite to the inner wall of the first plug-in wall 1021 on which the anti-foolproof rib 1022 is provided.

[0144] With the above structure, the fool-proof rib 1022 and the fool-proof groove 2014 are arranged so that the first plug-in surrounding wall 1021 can be inserted into the plug-in receiving groove 2013 only when the two are completely matched, thereby preventing the user from inserting the plug-in in reverse.

[0145] Furthermore, a plug-in seal 11 is provided on the outer side wall of the first plug-in enclosure 1021 , and when the first plug-in enclosure 1021 is inserted into the plug-in receiving groove 2013 , the plug-in seal 11 is sealed and matched with the inner wall of the second plug-in enclosure 2011 .

The end seal 106 is installed in the end seal accommodating groove and is sealed and mated with the inner wall of the end seal accommodating groove.

[0148] The above structure makes the structure of the first shell 1 more reasonable.

[0149] Further, an internal seal 12 is disposed on the first inner shell 104 , and when the first inner shell 104 is installed in the first outer shell 105 , the internal seal 12 is in sealing contact with an inner wall of the first outer shell 105 .
