[0027] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0028] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0029] Note: In this invention, one degree of freedom refers to the possibility that the mutually cooperating structural components can be combined, disassembled, or moved according to a specific design or direction.

[0030] The plugs and sockets in the embodiments shown below can be used with different connectors such as RJ-45 connectors, RJ11 connectors, RJ12 connectors, CAT6A connectors, RS-232 connectors, etc.

[0031] The quick plug connector with locking function according to the preferred embodiment of the present application comprises a plug 1 and a socket 2 which are arranged in cooperation with each other, the plug comprises a plug main body, and the socket comprises a socket main body which is provided with a first cavity for accommodating at least part of the plug main body in the assembled state. The plug main body can be provided with a second cavity, in which case, taking the RJ-45 connector as an example, the crystal head part can be correspondingly defined in the second cavity, and the network cable extends out of the opening at the tail of the plug main body; and the crystal part corresponding to the crystal head part can be defined in the first cavity of the socket main body, so that the crystal head and the crystal seat can be connected in cooperation when the socket and the socket are locked in cooperation, and vice versa to realize the disconnection of the two.

[0032] In order to meet the cooperation locking between the plug and the socket in long-term use, a locking structure can also be provided, which comprises a first limiting main body for providing a limiting operation in the cooperation plug-in direction of the plug and the socket, and a second limiting main body provided with a second release structure, the second release structure providing at least one freedom degree of release direction for the second limiting main body, so as to meet: in the unlocked state, the release direction is consistent with the plug-in direction (the consistency includes coincidence or parallelism, etc.), and the first limiting main body is moved in the plug-in direction through the second release structure; in the locked state, the release direction deviates from the plug-in direction to hinder the movement of the limiting main body in the plug-in direction; the first limiting main body is correspondingly defined to the plug or the socket; and the second limiting main body is correspondingly movably arranged to the socket or the plug relative to the first limiting main body through a second movable connecting piece, which provides at least one movement freedom degree for the second limiting main body to meet the adjustment of the second release structure relative to the plug-in direction, which includes the switching of the normal and the deviation. Unlike the existing automatic locking structure or the limiting structure described below, the locking structure is based on the adjustable requirement to realize the locking or unlocking operation, and a kind of active safety protection is realized.

[0033] As shown in Figures 1 to 4 The locking state of a possible locking structure is shown, which comprises a knob and a corresponding plug shell rib 11 arranged on the inner wall of the plug shell 10. The upper end of the knob has an opening and a locking groove 31 is formed on the knob main body 30. The width direction size and the like of the locking groove 31 can meet the passing of the plug shell rib 11 in the unlocked state, so as to realize the cooperation disconnection between the plug and the socket. The lower end of the knob is movably arranged in the pivot hole of the pivot hole part 21 of the outer wall of the socket main body part through the end 32 arranged as a pivot, so that the knob can be adjusted by the adjusting hole 101 under the cooperation of tools such as screwdrivers, and the plug shell rib 11 can be moved in the plug-in direction of the plug and the socket through the second release structure of the second limiting main body, so as to realize the cooperation locking between the plug and the socket. Figure 4When the passing direction of the locking groove 31 is consistent with the extension direction of the plug shell rib 11, the plug shell rib 11 can pass through the locking groove 31 freely, i.e. in the unlocked state. When the passing direction of the locking groove 31 is staggered with the extension direction of the plug shell rib 11, the plug shell rib 11 cannot pass through the locking groove 31 freely, i.e. in the locked state.

[0034] Further, the plug shell rib 11 can not be arranged at the central position of the plug shell 10 as shown, but can be arranged at the edge position close to the corner of the shell, so as to release the occupation of the core space of the product. In this way, the knob can also be arranged at the corresponding position on the outer wall of the socket. Further, the locking groove 31 can also be arranged at the edge of the knob body 30, so that the size and shape of the locking groove 31 need not be completely matched with the plug shell rib 11, but only need to be partially matched, i.e. the locking and unlocking can be realized. Figures 1-11

[0035] Of course, the locking structure can also adopt other feasible schemes. The movable structure can be an elastic structure having bending / restoring ability in the releasing direction or a door structure having opening / closing ability in the releasing direction. For example, the main body of the knob can be adjusted to be an anisotropic rubber strip (such as a rubber strip with different thicknesses in two directions or an oriented nylon fiber reinforced rubber strip, etc.), which has a lower bending strength in the passing direction of the locking groove 31, i.e. can easily bend and deform in this direction, so as to meet the unlocking passing requirement of the plug shell rib 11. In other directions, it is difficult to bend and deform, so as to meet the locking requirement of the plug shell rib 11 to be unable to pass.

[0036] For the quick plug-in connector with the locking function as shown in Figures 5-7 in the above, the plug shell rib 11 can be arranged at the edge position close to the corner of the shell, so as to release the occupation of the core space of the product. In this way, the knob can also be arranged at the corresponding position on the outer wall of the socket. Further, the locking groove 31 can also be arranged at the edge of the knob body 30, so that the size and shape of the locking groove 31 need not be completely matched with the plug shell rib 11, but only need to be partially matched, i.e. the locking and unlocking can be realized. Figures 1-4 ​On the basis of the feasible solution shown, the terminal 111 can also be provided on the plug, and the socket end 22 can also be provided on the socket, etc., without affecting the implementation of the locking / unlocking function of the locking structure in the present solution. The socket end 22 can also be provided with a fixing hole 23 for fixing the socket 2. As can be seen in the figure, the terminal 111 and the socket end 22 provide additional matching limiting structures or electrical connection structures for the corresponding plug and socket, such as the crystal head of the RJ-45 connector, which can be set in the second cavity of the plug body after being connected with the network telephone line, etc., and the network telephone line connected with the crystal head is further limited by the terminal 111; similarly, the socket end 22 can also meet similar connection requirements.

[0037] As shown in Figures 8-10 A quick plug connector assembly is shown, which can be provided with, but not limited to, the quick plug connector as described above and the communication cable 121, which is connected to the quick plug connector in cooperation. For example, it can be electrically connected with the plug through the plug terminal, and it can be electrically connected with the socket through the socket terminal.

[0038] The plug and the socket are provided with limiting structures for limiting the matching state of the two, including the first limiting structure provided on the plug and the second limiting structure provided on the socket, which cooperate with each other in the assembled state. The present solution regarding the locking structure is not directly related to whether the limiting structure is provided between the plug and the socket, including but not limited to the following embodiment solution. Specifically, the limiting structure can be Figure 11 As shown: including the clamping groove provided on the socket body and the cantilever with clamping protruding structure provided on the inner wall of the plug shell, etc., in the assembled state of the plug and socket, the clamping groove cooperates with the clamping protruding structure on the cantilever to limit, and the cantilever is unlocked, that is, the cooperation between the plug and the socket can be directly released.

[0039] In the embodiment shown in Figure 11In the case where the locking structure and the limiting structure coexist as shown in the drawings, the cooperation between the plug and the socket can be achieved by the limiting structure, such as the cooperation between the cantilever 13 and the clamping groove 24, to preliminarily lock the plug and the socket, and then the second limiting body of the locking structure is operated by the staff to adjust the release direction thereof to offset the cooperation direction between the plug and the socket where the first limiting body is located, so as to achieve the locking. It is noted that before this operation, in order to meet the installation requirement, the release direction of the second limiting body is consistent with the cooperation direction between the plug and the socket where the first limiting body is located. When unlocking, the second limiting body of the locking structure is operated by the staff to adjust the release direction thereof to return to the cooperation direction between the plug and the socket where the first limiting body is located, so as to complete the unlocking, and then the cantilever 13 is separated from the clamping groove 24, and the cooperation between the two is contacted, so that the subsequent unlocking of the plug and the socket can be completed.

[0041] Further, a communication system, including a plurality of the aforementioned communication devices. Such as a local area network communication station, etc., including a set of devices cooperated with each other, such as a monitoring host, a communication host, a switch, a signal device, etc. The communication system here refers to a set of devices composed of a plurality of the aforementioned communication devices of the same type or different types, and the system can be used for operation to realize some communication functions, such as information transmission.
