[0051] The electronic device according to the present disclosure can be a medical device having a display, a vehicle-mounted display device, or the like, and of course, the present disclosure is not limited to a display device such as a television. Figure 1 、 Figure 3 and Figure 4 The electronic device includes a housing 1a provided with at least one interface 11a, which can be an HDMI interface or other interface without a locking structure. Meanwhile, the electronic device can also include a plug 2a, which can include a plug portion 21a and a signal line 22a connected to the plug portion 21a, the plug portion 21a can be plugged into the interface 11a, and the signal line 22a can be connected to the end of the plug portion 21a away from the interface 11a. The plug 2a and the interface 11a can achieve signal transmission, and the specific structure is not specially limited here.

[0052] In order to prevent the plug 2a from falling off when subjected to vibration, the electronic device according to the present disclosure can also include a plug limiting device, as shown in Figures 1-5 The plug limiting device includes a fixed part 1, a blocking part 2, and a limiting assembly 3, wherein:

[0053] The fixed part 1 can be fixed to the housing 1a and has a first end and a second end distributed along a first direction X; the blocking part 2 is in sliding cooperation with the fixed part 1. The limiting assembly 3 includes a sliding part 31 and a plurality of positioning parts 32, each positioning part 32 is arranged on the fixed part 1 along the first direction X; the sliding part 31 is arranged on the blocking part 2; the sliding part 31 can cooperate with any positioning part 32 and be limited at the position of the positioning part 32, and can slide along the first direction X between the first end and the second end under the action of an external force.

[0054] The plug limiting device according to the present disclosure can be arranged on the housing 1a of the electronic device, and the first end faces the interface 11a. After the plug portion 21a of the plug 2a is plugged into the interface 11a, the blocking part 2 can be made to slide towards the plug 2a until it abuts against the plug 2a. After the sliding part 31 cooperates with a positioning part 32, the blocking part 2 no longer moves due to the limitation of the positioning part 32 on the sliding part 31. Therefore, the plug portion 21a can be blocked by the blocking part 2 to prevent it from loosening when subjected to vibration, thereby improving the reliability of the electronic device in operation. If the plug 2a is to be pulled out, an external force can be applied to remove or overcome the constraint of the positioning part 32 on the sliding part 31, so as to move the blocking part 2 towards the second end, remove the blocking of the plug portion 21a, and pull out the plug 2a.

[0055] The specific structure of the plug limiting device will be described in detail as follows:

[0056] As shown in Figures 1-4As shown, the plug limiting device can be arranged outside the interface 11a to prevent the plug 2a inserted into the interface 11a from falling off the interface 11a. In order to facilitate the arrangement of the plug limiting device, the shell 1a can have a bearing surface, which can have a boss, and the interface 11a can be arranged on the boss, and the bearing surface can extend along the axial direction of the interface 11a. The plug limiting device can be arranged on the bearing surface and opposite to the boss and outside the interface 11a.

[0057] The fixing member 1 has a first end and a second end distributed along the first direction X, and the first end can be arranged towards the interface 11a, and the second end is located on the side away from the interface 11a of the first end, that is, the distance between the first end and the interface 11a is greater than the distance between the second end and the interface 11a. At the same time, the fixing member 1 can be arranged on the shell 1a, for example, part of the fixing member 1 can be in an integrated structure with the shell 1a and can be formed at one time; or the fixing member 1 can also be an independent structure fixedly connected to the shell 1a.

[0058] The blocking member 2 is in sliding cooperation with the fixing member 1, and the limiting assembly 3 can limit the blocking member 2 at a plurality of positions distributed along the first direction X. Only by applying a certain external force, the blocking member 2 can slide along the first direction X to switch between the plurality of positions between the first end and the second end. The position of the blocking member 2 can be adjusted by the external force to block the insertion part 21a of the plug 2a away from the interface 11a. If the above external force is not applied or the external force is less than a certain threshold value, the position of the blocking member 2 can be maintained even if vibration occurs, thereby preventing the plug 2a from loosening.

[0059] As shown in Figure 1 and Figure 5 The blocking member 2 can include a sliding part 31 and a plurality of positioning parts 32, and each positioning part 32 can be arranged on the fixing member 1 along the first direction X. The sliding part 31 can be arranged on the blocking member 2. The sliding part 31 can cooperate with any one of the positioning parts 32 and be limited at the position of the positioning part 32. Under the action of artificial external force, the sliding part 31 can be disengaged from the positioning part 32 and slide along the first direction X between the first end and the second end.

[0060] The limiting assembly 3 will be described exemplarily as follows:

[0061] As shown in Figure 1 and Figure 5As shown in the first limiting assembly 3, the sliding part 31 is a protrusion provided on the blocking piece 2, and the positioning part 32 is a groove provided on the fixed piece 1. When the sliding part 31 cooperates with the positioning part 32, the sliding part 31 is at least partially limited in the positioning part 32. At this time, the protrusion cooperates in the groove, and the groove can limit the position of the protrusion. Under the condition that no sufficient external force is applied, the sliding part 31 cannot move out of the positioning part 32. Under the action of artificial external force, the sliding part 31 can be separated from the positioning part 32. At the same time, under the action of continuous external force, the sliding part 31 can be sequentially cooperated with a plurality of positioning parts 32 until the blocking piece 2 abuts against the plug-in part 21a, and the position of the plug-in part 21a is blocked. At this time, even if vibration occurs, the plug 2a can be blocked to prevent it from falling off.

[0062] Further, as shown in Figure 1 , Figure 5 and Figure 7 , the groove of the above-mentioned positioning part 32 can be circular, and the protrusion of the sliding part 31 can be spherical or semispherical, etc. In this way, while achieving positioning, more edges and corners can be avoided to prevent the risk of jamming or damage.

[0063] In addition, in the second limiting assembly 3, based on the above-mentioned limiting assembly 3, the positioning part 32 can also be a protrusion, and the sliding part 31 can also be a groove. The limiting principle is the same as above, only the concave-convex relationship is interchanged.

[0064] As shown in Figure 8 , in the third limiting assembly 3, the sliding part 31 can be hinged to the side of the blocking piece 2 close to the second end, and the intersection axis can be perpendicular to the first direction X, so that the sliding part 31 can rotate on the side. The positioning part 32 is a protrusion provided on the fixed piece 1. The thickness of any one positioning part 32 can decrease along the first direction X towards the second end, that is, gradually thinned in the direction away from the interface 11a. The sliding part 31 can rotate around the hinge shaft to achieve lifting and falling. When falling, the sliding part 31 can contact the positioning part 32, and when the end surface of the positioning part 32 close to the first end is abutted, the sliding part 31 is blocked on the side of the positioning part 32 close to the first end, at this time, it cannot slide towards the second end. When the blocking piece 2 and the sliding part 31 slide towards the first end, the sliding part 31 will rotate with the ups and downs of the positioning part 32 and can always contact the positioning part 32, but will not play a limiting role. Only under the action of external force, the sliding part 31 is lifted to separate the sliding part 31 from the positioning part, and the sliding part 31 can slide towards the second end.

[0065] For example, as shown in Figure 8As shown, the shape of the cross section of the positioning part 32 along the first direction X can be a right triangle or a right trapezoid, and it contracts in the direction away from the interface 11a, that is, the positioning part 32 can be a wedge-shaped structure that contracts in the direction away from the interface 11a; the positioning part 32 has a large end and a small end distributed along the first direction X, with the large end located on the side of the small end closer to the interface 11a, which is the end facing the interface 11a; the blocking member 2 can be manually moved towards the interface 11a along the first direction X. At this time, the sliding part 31 moves from the small end to the large end, and rises and falls with the undulation of the positioning part 32 during the movement. After moving to the side of the large end of any positioning part 32 close to the interface 11a, it can be blocked by the large end and cannot move in the opposite direction towards the small end, that is, it can only move in one direction; if the position of the blocking member 2 is to be adjusted in the direction away from the interface 11a, the sliding part 31 can be lifted to disengage it from the positioning part 32. At this time, the blocking member 2 can be slid towards the second end.

[0066] Furthermore, in other embodiments of this disclosure, the sliding part 31 can be fixed to the blocking member 2, and the blocking member 2 and the fixing member 1 can be directly separated when it is necessary to slide towards the second end. Of course, at least one of the positioning part 32 and the sliding part 31 can also be formed using an elastic material such as rubber, so that it is elastic and can deform under a large external force while having a blocking function, thereby allowing the blocking member 2 to move away from the interface 11a by a large external force.

[0067] The structure of fastener 1 is described below by way of example:

[0068] like Figures 1-5 As shown, in the first type of fastener 1, the fastener 1 may include a base 11 and a pressure plate 12, wherein:

[0069] The base 11 can be disposed on the housing 1a. The base 11 and the housing 1a can be an integral structure. In this case, the base 11 can be regarded as a part of the housing 1a. Alternatively, the base 11 and the housing 1a can also be independent structures connected by snap-fit ​​or by screws or other connecting parts.

[0070] The pressure plate 12 can be disposed on the base 11 and can be detachably connected to the base 11 by means of snap-fit ​​or screw connection. For example, the pressure plate 12 is provided with a first mounting hole 123, and the base 11 is provided with a second mounting hole 112 opposite to the first mounting hole 123. The inner wall of the second mounting hole 112 may be provided with threads, so that screws can be inserted into the second mounting hole 112 through the first mounting hole 123 and threadedly connected.

[0071] The pressure plate 12 has two ends distributed along the first direction X, one end of which can serve as the first end of the fixing member 1 and the other end of which can serve as the second end of the fixing member 1. At the same time, the pressure plate 12 is provided with a guide groove 121 extending along the first direction X. The guide groove 121 can be rectangular or oval, etc., and its structure is not specifically limited here.

[0072] As shown in Figures 1-5 the first fixing member 1, in the second embodiment, the first limiting assembly 3 is adopted, the blocking piece 2 can include a blocking portion 21, a cooperating portion 22 and a guide portion 23 connecting the blocking portion 21 and the cooperating portion 22, the blocking portion 21, the cooperating portion 22 and the guide portion 23 can be an integral structure, which can be plastic or other insulating materials; of course, the blocking portion 21, the cooperating portion 22 and the guide portion 23 can also be fixedly connected independent structures.

[0073] The guide portion 23 can pass through the guide groove 121 and slide fit with the guide groove 121, so as to move along the guide groove 121 in the first direction X under the constraint of the guide groove 121. The cooperating portion 22 is arranged on the side of the pressing plate 12 close to the base 11, and the blocking portion 21 is arranged on the side of the pressing plate 12 away from the base 11. At the same time, the length of the cooperating portion 22 in the second direction Y is less than the width of the guide groove 121, so that the pressing plate 12 can press the cooperating portion 22 on the base 11, and the blocking piece 2 is not easy to fall off, and the second direction Y and the first direction X can be perpendicular or intersected at an angle of not 90°. The sliding portion 31 of the limiting assembly 3 can be arranged at the end of the cooperating portion 22 away from the blocking portion 21, i.e. the bottom of the cooperating portion 22; each positioning portion 32 can be arranged on the base 11 and can be an integral structure with the base 11 or fixedly connected by clamping, bonding or the like. If the base 11 and the shell 1a are an integral structure, the positioning portion 32 can also be an integral structure with the shell 1a.

[0074] Based on the first fixing member 1, in the second embodiment, the first limiting assembly 3 is adopted, the sliding portion 31 can be arranged on the guide portion 23, and each positioning portion 32 can be arranged on the side wall of the guide groove 121, i.e. the side wall of the guide groove 121 is a concave-convex structure, and the sliding portion 31 on the surface of the guide portion 23 can cooperate with the positioning portion 32, and the specific principle can be referred to the first limiting assembly 3 above, which will not be described here.

[0075] As shown in Figure 8 based on the first fixing member 1, in the third embodiment, the second limiting assembly 3 is adopted, the sliding portion 31 can be hingedly connected to the side surface of the cooperating portion 22 close to the second end, i.e. the side surface of the cooperating portion 22 away from the interface 11a; in order to facilitate the hinging, a lug can be formed on the side surface, and a hinge shaft perpendicular to the first direction X is arranged in the lug, the sliding portion 31 is sleeved outside the hinge shaft and rotates with the lug; and the positioning portion 32 is arranged on the base 11.

[0076] In some embodiments of the present disclosure, the base 11 can be provided with a receiving groove 111 extending along the first direction X, and the fitting portion 22 of the blocking piece 2 can be arranged in the receiving groove 111 and in sliding fit with the receiving groove 111, so that the sliding track of the blocking piece 2 can be limited by the receiving groove 111, and meanwhile, the thickness of the fitting portion 22 is not greater than the depth of the receiving groove 111, so that the fitting portion 22 is embedded in the base 11, and the pressing plate 12 can be attached to the surface of the base 11 without being raised, which is beneficial to reducing the overall thickness. The shape of the receiving groove 111 can be the same as that of the pressing plate 12, for example, both of them are kidney-shaped, but the size of the pressing plate 12 is greater than that of the receiving groove 111, so that the pressing plate 12 can cover the receiving groove 111. If the base 11 and the shell 1a are in an integral structure, there can be no physical boundary between the base 11 and the shell 1a, and the receiving groove 111 can also be regarded as an opening arranged on the shell 1a.

[0077] If the positioning portion 32 of the limiting assembly 3 is arranged on the bottom surface of the receiving groove 111, and if the positioning portion 32 is arranged on the pressing plate 12, the receiving groove 111 is not provided with the positioning portion 32, and the fitting portion 22 can slide in the receiving groove 111.

[0078] As shown in Figure 1 and Figure 5 , in some embodiments of the present disclosure, in order to facilitate the installation and removal of the blocking portion 21, an avoiding hole 122 for the blocking portion 21 to pass through can be arranged on the pressing plate 12, and the avoiding hole 122 is located at one end of the guide groove 121 close to the second end and in communication with the guide groove 121, and the width of the guide groove 121 in the second direction Y is greater than the width of the guide groove 121, so that the blocking portion 21 can pass through the pressing plate 12 through the avoiding hole 122 and then slide into the guide groove 121, and if it is needed to take out the blocking portion 21, the blocking portion 21 can be slid into the avoiding hole 122 along the guide groove 121, and then the blocking portion 21 can be taken out. For the blocking portion 21 including the fitting portion 22 and the guide portion 23, the width of the fitting portion 22 in the second direction Y is smaller than the width of the avoiding hole 122, so that the fitting portion 22 cannot be taken out of the guide groove 121 in a direction perpendicular to the pressing plate 12, but can be taken out of the avoiding hole 122, which is convenient for the installation and removal of the blocking portion 21.

[0079] Further, as shown in Figure 1 and Figure 5 , in some embodiments of the present disclosure, a protrusion 113 can also be formed on the base 11, which can be arranged in the avoiding hole 122 and not in contact with the side wall of the avoiding hole 122, and the protrusion 113 and the avoiding hole 122 can be used for coarsely positioning the pressing plate 12 for installation.

[0080] As shown in Figure 8As shown in the second fixing member 1, the fixing member 1 can include a pressing plate 12, and the base 11 described above can be omitted; the pressing plate 12 can be detachably connected with the shell 1a through clamping or using screws or the like. The blocking member 2 can include a blocking portion 21 and a fitting portion 22, the fitting portion 22 can be sleeved outside the pressing plate 12, and is in sliding fit with the pressing plate 12 and can slide along the first direction X; the blocking portion 21 is arranged on the side of the fitting portion 22 away from the pressing plate 12, and is used for blocking the plug-in portion 21a of the plug 2a. At the same time, the sliding portion 31 can be arranged on the inner surface of the fitting portion 22, and each positioning portion 32 can be arranged on the surface of the pressing plate 12. For example, the fitting portion 22 can be a U-shaped structure surrounded by two side plates and a middle plate, and the middle plate is connected between the two side plates; the fitting portion 22 can be sleeved outside the pressing plate 12, and the middle plate is located on the side of the pressing plate 12 away from the shell 1a, and the middle plate can be in sliding fit with the pressing plate 12. The sliding portion 31 can be arranged on the inner wall of the side plate, i.e. the surface of the side plate close to the pressing plate 12; and the positioning portion 32 is arranged on the side surface of the pressing plate 12, opposite to the side plate;

[0081] Further, as shown in some embodiments, Figure 8 the surface of the fitting portion 22 close to the pressing plate 12 can be provided with a sliding block 14 through fixed connection or one-piece forming or the like, the sliding block 14 can be in sliding fit in the sliding groove 13, so as to guide the fitting portion 22 to slide along the first direction X; at the same time, the sliding groove 13 and the sliding block 14 are matched in shape and size, and the sliding groove 13 can be a dovetail groove, or a T-shaped groove or the like, which can prevent the sliding block 14 and the blocking member 2 from being separated from the pressing plate 12. In addition, in order to facilitate installation and disassembly, the sliding groove 13 can be a through groove with both ends penetrating in the first direction X.

[0082] For the above embodiments, further, the distance between the two adjacent positioning portions 32 in the first direction X can be not greater than the length of the sliding portion 31 in the first direction X, so that the space between the two adjacent positioning portions 32 which does not play a limiting role can be reduced as much as possible, and the positions which can play a limiting role can be increased.

[0083] As shown in Figure 3 , Figure 4 and Figure 6As shown, in some embodiments of the present disclosure, the blocking part 21 is in a ring structure, and the signal line 22a can pass through the ring structure, so that the blocking part 21 can block the plug-in part 21a from the periphery of the signal line 22a. Further, the blocking part 21 can have a notch 211, i.e., the blocking part 21 is an open ring structure. During installation, the signal line 22a can be placed into the ring structure of the blocking part 21 from the notch 211, and then the blocking part 2 is slid in the first direction X, so that the blocking part 21 is in contact with the plug-in part 21a, and the blocking part 21 blocks the plug-in part 21a from falling off by the limiting action of the limiting assembly 3. If it is necessary to pull out the plug 2a, an external force can be used to slide the blocking part 2 in the first direction X away from the interface 11a, so as to overcome the blocking action of the limiting assembly 3, and make the blocking part 2 and the plug-in part 21a separated. At this time, the plug 2a can be pulled out.

[0084] In addition, the blocking part 21 with the notch 211 can have a certain elasticity, and it is not easy to jam or pinch off the signal line 22a, and it can be adapted to signal lines 22a of different diameters. Further, the two ends of the notch 211 of the blocking part 21 can be provided with flanges 212 extending in opposite directions, i.e., the flanges 212 extending outwardly from the notch 211, which can increase the contact surface with the hand, facilitate manual holding, and move the blocking part 2.
