In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The utility model provides a socket and a connector, wherein the connector comprises the socket and a plug matching the socket. Figures 1 to 2 As shown, the socket comprises a housing 2, a socket body 1, a protective cover 3 and a distance detection component 4. The socket body 1 is placed in the housing 2; the protective cover 3 is hinged on the housing 2. The structure and interconnection relationship of the housing 2, the socket body 1 and the protective cover 3 can be implemented by any structure in the prior art.

[0028] The distance detection component 4 includes a distance sensor 41 and a signal output line 42 connected to the distance sensor 41. The distance sensor 41 is fixed on the socket body 1. The distance sensor 41 is used to detect the distance to the protective cover 3 when the protective cover 3 is covered on the socket body 1 and / or to detect the distance to the plug end face of the plug when the plug is plugged into the socket body 1.

[0029] One end of the socket body 1 is a mating end face, which contacts the mating end face of the plug when connected with the plug; the other end is connected with the signal line.

[0030] By arranging a distance detection component on the socket body, the distance to the protective cover 3 is detected when the protective cover 3 is covered on the socket body 1, and / or the distance to the plug end face of the plug is detected when the plug is plugged into the socket body 1, so as to detect whether the protective cover is closed in place and / or detect whether the plug is plugged in place, thereby avoiding damage caused by the exposed core and / or the loosening of the socket cover during the operation of the vehicle.

[0031] Specifically, there are many ways to implement the distance detection component 4, such as an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, etc.

[0032] Since the gap between the protective cover and the plug-in end face of the socket body when the protective cover is covered on the socket body 1 is different from the gap between the plug and the plug-in end face of the socket body when the plug is inserted into the socket body 1, different states can be monitored by detecting the distance. When the socket needs to monitor two states, one distance detection component 4 can be used to monitor the corresponding state respectively; or one distance detection component 4 can be used to detect and monitor the two states respectively.

[0033] When two distance detection components 4 are used to monitor corresponding states respectively, the sensitivities of the distance sensors of the two distance detection components 4 are different.

[0034] When one distance detection component 4 is used to detect and monitor the two states respectively, the structure can be simplified and the cost can be reduced. In this case, the distance sensor 41 can be a photoelectric switch, which includes a sensing end 41 and a sensitivity adjuster 43 for adjusting the sensitivity of the sensing end. The sensitivity adjuster 43 is generally a knob equipped with the photoelectric switch, and the sensitivity can be adjusted by adjusting the knob. This method is the most direct and convenient.

[0035] The signal output line 42 is directly connected to the monitoring circuit, which may be a train control system, etc. The photoelectric switch is used to monitor whether the protective cover is properly closed or the plug is properly plugged in by adjusting the sensitivity of the sensing end, which can simplify the process of determining whether the monitoring circuit end is properly plugged in and simplify the complexity of the system.

[0036] In order to facilitate the installation and wiring of the distance sensor assembly, a mounting hole is provided on the socket body 1, and the distance sensor 41 is installed in the mounting hole. The sensor assembly is installed using the mounting hole, and its signal output line can be directly led out through the mounting hole. The number of mounting holes can be set according to the number of distance sensors 41.

[0037] In order to enhance the stability of the protective cover 3 when closed and the stability of the plug when docked, a locking structure fixed on the shell 2 is also included on the basis of any of the above structures. The locking structure is used to lock the protective cover 3 and the plug when the protective cover 3 is closed and the plug is docked.

[0038] Specifically, refer to Figures 3 to 5 As shown, a first locking block 31 is provided on the protective cover 3; the locking structure includes a guide rod 51, a slider 52, a pressure block 53 provided on the slider 52 for locking the first locking block 31, a handle assembly 54 for controlling the movement of the slider 52 along the guide rod 51, and a locking assembly 55 for achieving state locking of the handle assembly 54.

[0039] After the protective cover 3 covers the socket body 1 , the handle assembly 54 is operated, and the slider 52 drives the pressing block 53 to move downward and press on the first locking block 31 , and the locking assembly 55 is used to lock the handle assembly 54 .

[0040] In order to improve the locking stability of the first locking block 31, the pressing block 53 can be a pressing block with a hook body, such as Figure 2 , 3 shown.

[0041] In order to simplify the structure, the first locking block 31 can directly adopt the end of the protective cover 3 to operate the handle.

[0042] The handle assembly 54 and the locking assembly 55 can be implemented in a variety of structures. In order to simplify the structure and facilitate operation, the handle assembly 54 can adopt the following structure, for example, Figures 3 to 5 The handle assembly 54 includes an operating handle 541 with one end rotatably connected to the slider 52, and a connecting rod 542 with two ends rotatably connected to the operating handle 541 and the housing 2, and a locking groove 5411 is provided on the operating handle 541; correspondingly, the locking assembly 55 includes a locking plate 551 detachably connected to the slider 52 and a hook 552 provided on the locking plate for cooperating with the locking groove 5411 to achieve locking of the operating handle 541 and the slider 52.

[0043] The above locking structure can not only lock the protective cover, but also lock the plug. Correspondingly, a second locking block is provided on the plug, and the position of the second locking block corresponds to the position of the pressing block 53.

[0044] With the above structure, the locking structure has the same principle for locking the protective cover or the plug. Take the locking of the protective cover as an example:

[0045] When the protective cover is not closed, its status is as follows Figure 3 Remove the locking assembly 55, and put the protective cover on the socket body 1. Figure 3In the state shown, the operating handle 541 is turned clockwise. At this time, driven by the handle assembly 54, the slider 52 moves to the right along the guide rod 51 until the pressing block presses the first locking block 31. The protective cover can be locked by inserting the hook 552 of the locking assembly 55 into the locking groove 5411 of the operating handle 541 and re-fixing the locking sheet 551 on the slider 52. Figure 5 shown.

[0046] The principle of the locking structure to achieve plug locking is the same as that of the protective cover, so it will not be described in detail in this solution.

[0047] The above connector can improve the plug connection stability through the locking structure, and can also improve the stability of the protective cover to prevent the plug from being loosened or the protective cover from being loosened. When the plug is loosened or the protective cover is loosened, the distance detection component 4 can further realize detection.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
