Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a plug - in structure of a mobile electronic device for examinations, which can prevent an external plug - in from being accidentally disconnected. Background Art

[0002] With the advent of the electronic information era, in a large number of jobs that use paper as a medium, such as education, writing, and office work, paper products have been largely replaced by electronic devices, which not only improves work efficiency but also reduces the use of paper and has a less adverse impact on the environment.

[0003] However, since electronic devices, especially mobile electronic devices, usually need to be plugged with various external devices to meet the work requirements in different scenarios to meet daily use.

[0004] Therefore, in an examination environment where mobile electronic devices are used, in order to prevent cheating, the external plug - ins of electronic devices will be paired and locked. Once the external plug - in is disconnected from the electronic device, the current examination will be judged invalid, and the examinee needs to retake the examination.

[0005] However, in actual applications, situations where external plug - ins such as headphones are disconnected from mobile electronic devices such as tablets may occur, and the disconnection of the headphones from the tablet will lead to the termination of the examination.

[0006] Although some industry insiders also advocate using wireless communication technology to solve the problem of retaking the examination caused by the disconnection between electronic devices and external plug - ins, wireless communication technology is usually based on infrared technology or radio technology. The former cannot cope with the situation of too many examinees, and the latter cannot meet the requirement of shielding radio signals in the examination room.

[0007] Therefore, how to prevent the external plug - in of a mobile electronic device for examinations from being accidentally disconnected has become a technical problem that needs to be urgently solved by those skilled in the art. Content of the Utility Model

[0008] In view of the above - mentioned defects of the prior art, the utility model provides a plug - in structure of a mobile electronic device for examinations that can prevent an external plug - in from being accidentally disconnected, and the achieved purpose is to prevent the external plug - in of a mobile electronic device for examinations from being accidentally disconnected.

[0009] To achieve the above - mentioned purpose, the utility model discloses a plug - in structure of a mobile electronic device for examinations that can prevent an external plug - in from being accidentally disconnected, including a mobile electronic device with a slot; the slot is used for plugging an external plug - in, and on one side of the slot, there is an elastic insertion piece that can extend out or retract from the side wall of the slot along the normal direction of the insertion and extraction direction of the external plug - in.

[0010] The elastic insertion piece is movably connected to the mobile electronic device, and one end can extend out or retract from the side wall of the slot.

[0011] When the external plug-in is fully inserted into the slot, a positioning groove with a clearance fit is provided on the outer wall corresponding to the end of the elastic insert protruding from the side wall of the slot.

[0012] Preferably, the slot and the external plug-in are headphone jacks of a matching type-c model.

[0013] More preferably, the positioning grooves are provided on two opposite outer sides among the four outer sides of the external plug-in.

[0014] Preferably, a spring is provided at the other end of the elastic insert away from the slot.

[0015] Preferably, the elastic insert is provided with a paddle extending outside the housing of the mobile electronic device.

[0016] More preferably, the extending direction of the paddle is perpendicular to the reciprocating movement direction of the elastic insert inside the mobile electronic device.

[0017] Preferably, the mobile electronic device is a tablet computer for examinations.

[0018] Advantages of the present utility model:

[0019] The application of the present utility model can prevent the external plug-in of the mobile electronic device for examinations from being accidentally disconnected.

[0020] The concept, specific structure and technical effects of the present utility model will be further described below in conjunction with the drawings to fully understand the purpose, features and effects of the present utility model. Description of the Drawings
