[0040] The plug component at least includes: a plug housing, a jack, a tail cover, a wire sealing body and a tail nut; the jack is integrally stamped and arranged in the plug housing, and has a contact portion and a crimping portion connected by a connecting portion; the crimping portion is outer-circuited with a tail cover, the tail nut is connected to the plug housing, and the wire sealing body is compressed in the tail nut at the rear end of the crimping portion; the socket component at least includes: a socket housing, a connecting sleeve, an insulating cap and a pin, and the insulating cap is fixed to one end of the pin; the pin is installed in the socket housing and can prevent the pin from withdrawing; the connecting sleeve limit sleeve is arranged outside the socket housing and can realize 360° rotation; the socket component is plugged into the contact portion of the jack, the contact portion is inserted between the pin and the socket housing, and is positioned by the outer circular protrusion outside the connecting sleeve and the plug housing.

[0041] Specifically, the plug component A is composed of a plug housing A1, a secondary lock A2, a socket A3, an O-ring A4, a tail cover A5, a sealing body A6, a tail nut A7, a reed A9 and a sealing ring A8; preferably, in this embodiment, the socket is integrally stamped, and the socket and the plug housing are integrally injection molded, which has high feasibility as long as the positioning on the mold and the size of the sealing are reasonable. The reed A9 is installed in the groove of the inner hole of the socket, and the anti-touch finger is generated by the root of the plug housing A1 during the integral injection molding. Refer to the attached Figure 1 The secondary lock is assembled from the upper part of the plug housing to the plug housing, and can be covered on the primary lock A11 in the plug housing; the sealing ring A8 and the O-ring A4 are fixed to the plug housing through radial interference and axial limit, the sealing ring A8 is sleeved on the lower part of the plug housing, and the O-ring A4 is sleeved on the outside of the plug housing A1 and contacts with the tail nut A7; the tail cover A5 is sleeved on the outside of the tail of the jack; the tail nut A7 is locked with the plug housing through threads, and the sealing body A6 is compressed in the jack and the rear tail nut, that is, the tail of the plug assembly, thereby playing a sealing role.

[0042] The socket component B consists of a socket housing B1, a connection sleeve B2, a sealing gasket B3, an insulating cap B4 and a pin B5. The insulating cap B4 is fixed to one end of the pin B5 by its own elastic claws; the pin is installed in the socket housing B1, and the convex ring on the outside of the pin cooperates with the elastic claws in the socket housing to prevent it from withdrawing; the connection sleeve B2 is sleeved on the outside of the socket housing, and is pressed to the outside of the socket housing B1 by the inner hole convex point, and can be rotated 360 degrees; the sealing gasket B3 is installed in the groove of the flange and fixed to the socket housing by the interference convex point.

[0043] The jack assembly is composed of a jack and a reed arranged in the jack, and the pin assembly is composed of a pin and an insulating cap inserted at one end of the pin. The pin assembly is connected with the jack assembly to achieve current conduction, and the anti-touch finger stick can prevent personal injury caused by accidental touch.

[0044] In a further improvement of this embodiment, the plug housing A1 includes a primary lock A11, a secondary lock stop convex point A12, a secondary lock limit convex part IA13, a secondary lock limit convex part IA14, a keyway A15, an anti-touch finger rod A16 and other structures. Its main function is to fix the jack assembly, and realize the plugging and primary locking with the socket component. It is also the main body that "carries" other plug parts and ensures sufficient electrical clearance and creepage distance.

[0045] Specifically, the secondary lock A2 includes a moving part A21, a locking part A22, a pressing protrusion A23 and a covering part A24. The moving part is arranged between the locking parts, the pressing protrusion connects the moving part and the locking part, and the covering part is located on the opposite side of the pressing protrusion. The main function of the secondary lock is to achieve secondary locking of the product.

[0046] The sealing ring A8 and O-ring A4 are used to achieve sealing protection of the product. The sealing ring is the sealing protection of the plug part and the socket part, and the O-ring is the sealing protection after the thread of the tail nut and the plug housing is tightened.

[0047] The sealing body A6 is used to provide sealing protection for the rear cables.

[0048] The tail cover A5 is sleeved on the outer side of the rear end of the jack to protect the rear end of the jack and to limit the axial position of the sealing body.

[0049] The tail nut A7 is used to connect the plug housing, fix and limit the wire seal, and ensure sufficient electrical clearance and creepage distance.

[0050] Another improvement of this embodiment is that the socket housing B1 includes a flange B11, serrated teeth IB12, elastic claws, and bosses B13, whose main functions are to fix the pin assembly, realize the installation and fixation of the socket component, and realize the plugging and one-time locking with the plug component. It is also the main body that "carries" other socket component parts and ensures sufficient electrical clearance and creepage distance.

[0051] The inner hole of the connecting sleeve B2 is provided with several convex points and several serrated teeth Ⅱ B22. The function of the convex points is to press into the socket housing by interference fit to ensure the fixation of the connector on the socket housing. The main function of the serrated teeth Ⅱ is to mesh with several serrated teeth Ⅰ on the socket housing when the connecting sleeve rotates, thereby making a "click" sound and increasing the feel of the connecting sleeve when rotating. There are outer circle convex points B23, keys B24 and foolproof keys B25 on the outer circle. The function of the outer circle convex points is to achieve one-time locking when the socket component and the plug component are plugged in. The key cooperates with the plug housing to achieve accurate positioning and smooth plugging during plugging. The foolproof key can avoid wrong plugging and mis-plugging when the plug and socket are plugged in.

[0052] The sealing gasket B3 is assembled in the groove on the flange of the socket housing, and its main function is to ensure the protection and sealing of the flange and the installation panel.

[0053] More specifically, in this embodiment, the primary lock A11 of the plug housing A1 is a cantilever beam structure, and the joint part A111 with the plug housing is located at the middle and two sides of the primary lock; there is a slot A112 in the middle of the primary lock, which facilitates the secondary lock locking part A22 to move up and down in this space. Its structural characteristics are that there is a height difference between the front end A113 and the rear end A114, and the rear end is higher than the front end. The secondary lock stop convex point A12, its function is to limit the secondary lock moving part A21. In the process of the secondary lock locking to the front end, it can be used as a stop convex point; in the process of the secondary lock unlocking to the rear end, it can be used as a stop convex point. The secondary lock limit convex part IA13, its main function is: when the secondary lock is in the locked state, it contacts with the limit convex point at the upper end of the secondary lock to reduce the up and down movement of the secondary lock; when the secondary lock covers the primary lock and is pressed to unlock, it limits its upward movement. The secondary lock limit protrusion ⅡA14, when the secondary lock is in the locked state, covers the primary lock A11 and presses down the secondary lock A2 that is operated incorrectly to limit the position. The keyway A15 is mainly used to ensure that the plug component A and the socket component B are inserted at the correct angle. The anti-touch finger rod A16 is used to prevent fingers from touching the metal parts inside, thereby causing safety accidents.

[0054] The moving part A21 of the secondary lock is located on both sides of the secondary lock and is composed of two cantilevers; there is a raised part IA211 at the front end, which is used to limit the position backward to prevent exit when unlocking; there is a raised part IA212 at the rear end, which is used to limit the position forward when locking. The locking part A22 is located in the middle of the secondary lock and is a cantilever; there is a raised part ⅢA221 at the front end, and the raised part Ⅲ has a small chamfer at the front end and a large chamfer at the rear end. The pressing raised part A23 is located at the rear end of the secondary lock. Its function is to facilitate the secondary lock A2 to cover the primary lock A11 for the press-to-unlock operation after the secondary lock A2 is unlocked. The covering part A24 cooperates with the rear end A114 of the primary lock on the plug housing to make the secondary lock A2 "cover" the primary lock A11.

[0055] The flange B11 of the socket housing has a groove for installing a sealing gasket. The sawtooth IB12 is used to mesh with the sawtooth II on the connecting sleeve, thereby making a "click" sound. The boss B13 is used to ensure that the connecting sleeve is limited and prevented from exiting after being pressed in.

[0056] The inner hole convex point B21 of the connecting sleeve B2, which is several in number, cooperates with the boss B13 of the socket housing to ensure the fixation of the connecting sleeve. The serrated teeth II B22 cooperate with the serrated teeth I B12 of the socket housing. The outer circle convex point B23 has a straight surface at the rear end and a large inclined surface at the front end, and its function is to cooperate with the plug housing to achieve one-time locking. The key B24 cooperates with the keyway A15 on the plug housing to ensure that the plug component A and the socket component B can be inserted normally at a specific position. The foolproof key B25 prevents the plug component A and the socket component B from being inserted incorrectly when they are inserted.

[0057] The jack A3 is formed by stamping. The contact part A31 has a groove in the inner hole, which can be loaded with the spring A9. The crimping part A32 is used to cover the cable core wire. The connecting part A33 connects the contact part and the crimping part, and can also increase the bearing area and the current carrying capacity of the jack.

[0058] The locking process is as follows:

[0059] Firstly, the secondary lock A2 is installed on the plug housing A1 through its covering part A24, and forms a cooperation with the primary lock A11 on the plug housing, that is, the two can move forward and backward, but the downward pressing movement must be completed by the two as a whole; when the plug component A and the socket component B are not plugged in, the secondary lock A2 is completely fixed in the plug housing A1 in the front and rear directions, because the raised part A211 on the front side of the secondary lock movement part contacts the secondary lock stop convex point A12 on the plug body, preventing the secondary lock A2 from withdrawing backward, and at the same time, the raised part Ⅱ A221 on the front side of the secondary lock locking part contacts the groove A112 of the primary lock on the plug body, limiting the forward movement of the secondary lock A2.

[0060] Then, when the plug component A and the socket component B are plugged together, the outer convex point B23 of the socket housing enters the front end of the slot A112 of the primary lock of the plug housing, and the primary lock A11 is locked. At the same time, the outer convex point B23 of the socket housing contacts the convex part IIA221 at the front end of the locking part of the secondary lock, and the convex part IIA221 at the front end of the locking part of the secondary lock is in a "lifted" state, so the forward limit of the secondary lock A2 fails.

[0061] Finally, push the secondary lock A2 forward, and the convex part II A212 on the rear side of the secondary lock moving part contacts the secondary lock stop convex point A12 on the plug housing. At this time, the secondary lock A2 is just in the locked state, and the convex part III A221 of the locking part of the secondary lock just exceeds the end face A113 of the front end of the primary lock. At this time, both the primary lock A11 and the secondary lock A2 are in the locked state.

[0062] The unlocking process is as follows:

[0063] The unlocking operation is the opposite of the locking operation. First, pull the secondary lock A2 backwards, and the secondary lock returns from the locked position to the outer convex point B23 at the front end of the socket housing. At this time, the secondary lock A2 is in the unlocked state. At the same time, the front convex part IA211 of the moving part of the secondary lock also contacts the stop convex point A12 of the secondary lock of the plug body, limiting the position and ensuring that the secondary lock A2 will not exit due to excessive movement.

[0064] Then, press the secondary lock again to press the protrusion A23. At this time, the secondary lock is covered on the primary lock, and the two are shaped like a whole. At this time, the front end A113 of the primary lock slot will be tilted upward. When the tilting height exceeds the boss on the socket shell, the primary lock A11 is unlocked.

[0065] Finally, pull the plug part A to completely separate it from the socket part B, and the unlocking process is completed.

[0066] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
