Description

Technical Field

[0001] The present invention relates to the technical field of electronic devices, and particularly to a plug fastening and loosening prevention mechanism and a socket device. Background Art

[0002] At present, many electronic product plugs do not have fastening and loosening prevention devices, such as general USB connectors, DC power connectors, HDMI connectors, etc. Refer to Figure 4 , such plugs generally consist of the main body of the first plug, the metal end of the first plug, and a plug transition section. These plugs are very easy to loosen under some vibration and external force environments, resulting in unstable signal and power transmission.

[0003] Of course, there are some special anti-loosening and waterproof connectors, but these connectors have complex structures, high prices, and it is very cumbersome to transform the plug and socket connectors of these electronic products that originally do not have anti-loosening devices. And after the metal end of the first plug is inserted into the socket, due to the lack of an anti-loosening device, when vibrating or being stretched by an external force, the main body of the first plug is prone to loosen, and the metal end of the first plug will be pulled out of the first socket of the socket. This situation will greatly reduce the service life of the plug and the socket. Summary of the Invention

Detailed implementation mode

[0042] The following will, with reference to the accompanying drawings and embodiments, further describe in detail the specific implementation mode of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0043] First of all, it should be noted that the top, bottom, upward, downward and other orientations mentioned in this article are defined relative to the directions in each drawing. They are relative concepts and can therefore change according to their different positions and different practical states. Therefore, these or other orientations should not be used as restrictive terms.

[0044] It should be noted that the term "including" does not exclude other elements or steps, and "a" or "one" does not exclude a plurality.

[0045] In addition, it should also be pointed out that for any single technical feature described or implied in the embodiments of this article, or any single technical feature shown or implied in the drawings, combinations can still be continued between these technical features (or their equivalents) to obtain other embodiments of the present application not directly mentioned in this article.

[0046] It should also be understood that the terms "first", "second", etc. are used in this article to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present application, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0047] It should be noted that in different drawings, the same reference numerals denote the same or substantially the same components.

[0048] As Figure 1 , Figure 8 , and Figure 10 shown, a plug fastening and anti-loosening mechanism according to a preferred embodiment of the present invention includes: a housing 2, a first buckle seat 5, a second buckle seat 6, a third buckle seat 10, a fourth buckle seat 11, a first fastener 7, and a second fastener 13.

[0049] The housing 2 has a receiving cavity for receiving the socket 1, and the housing 2 is provided with a second socket 21 through which the metal end of the second plug can be inserted and communicated with the receiving cavity, and a first socket 31 through which the metal end 42 of the first plug can be inserted and communicated with the receiving cavity, so as to facilitate the metal end 42 of the first plug to be inserted into the socket 1 in the receiving cavity through the first socket 31.

[0050] Wherein, in order to facilitate the distinction between the combination of the first buckle seat 5 and the second buckle seat 6, and the composition of the third buckle seat 10 and the fourth buckle seat 11, the present application sets the fixing objects of the first buckle seat 5 and the second buckle seat 6 as the first plug 4, and sets the fixing objects of the third buckle seat 10 and the fourth buckle seat 11 as the second plug. It can be understood that the first plug 4 and the second plug can be either the same structure or different structures, which are not limited herein.

[0051] The first buckle seat 5 and the second buckle seat 6 enclose a first limiting space adapted to the main body 41 of the first plug. The main body 41 of the first plug is limited in the first limiting space by the first buckle seat 5 and the second buckle seat 6, so that the main body 41 of the first plug cannot be pulled out of the first limiting space, and the first buckle seat 5 and the second buckle seat 6 are fixed on the housing 3 by the first fastener 7, so that the first plug 4 cannot be removed without removing the first buckle seat 5 and the second buckle seat 6. The third buckle seat 10 and the fourth buckle seat 11 enclose a second limiting space adapted to the main body of the second plug. The main body of the second plug is limited in the second limiting space by the third buckle seat 10 and the fourth buckle seat 11, so that the main body of the second plug cannot be pulled out of the second limiting space, and the third buckle seat 10 and the fourth buckle seat 11 are fixed on the side surface of the housing 2 by the second fastener 13, so that the second plug cannot be removed without removing the third buckle seat 10 and the fourth buckle seat 11.

[0052] With the above structure, the present application solves the problem that when the metal ends of the first plug and the second plug are inserted into the socket 1, due to the lack of a loosening prevention device, the main bodies of the first plug and the second plug are likely to become loose when vibrating or being stretched by an external force. Furthermore, it maintains the fastening of the metal ends of the first plug and the second plug to the socket 1, which is beneficial to improving the service life of the first plug 4, the second plug, and the socket 1.

[0053] Specifically, the accommodating cavity needs to be adapted to the shape and size of the socket 1 so that the socket openings of the socket 1 can correspond to the first socket opening 31 and the second socket opening 21 on the housing 3.

[0054] See Figure 1 and Figure 5 In a possible embodiment, the first buckle seat 5 of the embodiment of the present invention includes: a first baffle 51, a first limiting block 52 provided on the first baffle 51, and a second limiting block 53 provided on the first baffle 51.

[0055] See Figure 1 and Figure 5 The second buckle seat 6 includes: a second baffle 61, a third limiting block 62 provided on the second baffle 61, and a fourth limiting block 63 provided on the second baffle 61. The third limiting block 62 is provided between the first limiting block 52 and the housing 3. The second limiting block 53 is provided between the fourth limiting block 63 and the housing 3, and the first buckle seat 5 and the second buckle seat 6 are fixed by the first fastener 7, so that the first baffle 51, the first limiting block 52, the second limiting block 53, the second baffle 61, the third limiting block 62, and the fourth limiting block 63 enclose a first limiting space adapted to the main body 41 of the first plug. When the main body 41 of the first plug is inserted into the first limiting space, it is restricted by the first baffle 51, the first limiting block 52, the second limiting block 53, the second baffle 61, the third limiting block 62, and the fourth limiting block 63, so that the main body 41 of the first plug cannot be pulled out of the first limiting space.

[0056] Further, see Figure 1 and Figure 2 The first fastener 7 includes: a first bolt 71 and a second bolt 72. A first hole is opened on the first limiting block 52, a second hole is opened on the third limiting block 62, and a third hole is opened on the housing 3. The first hole, the second hole, and the third hole all extend along a first predetermined straight line direction. The first bolt 71 is sequentially inserted into the first hole, the second hole, and the third hole to fix the first limiting block 52, the third limiting block 62, and the housing 3 to each other.

[0057] A fourth channel is formed in the fourth limiting block 63, a fifth channel is formed in the second limiting block 53, and a sixth channel is formed in the housing 3. The fourth channel, the fifth channel, and the sixth channel all extend along a second predetermined straight line direction. The second bolt 72 is sequentially inserted into the fourth channel, the fifth channel, and the sixth channel to fix the fourth limiting block 63, the second limiting block 53, and the housing 3 to each other.

[0058] Specifically, the first predetermined straight line direction is perpendicular to the housing 3 so that the first bolt 71 can be screwed into the third channel perpendicular to the housing 3. Among them, the first channel, the second channel, and the third channel are all bolt holes. The second predetermined straight line direction is perpendicular to the housing 3 so that the second bolt 72 can be screwed into the sixth channel perpendicular to the housing 3. Among them, the fourth channel, the fifth channel, and the sixth channel are all bolt holes.

[0059] In a possible embodiment, both the first limiting block 52 and the third limiting block 62 are square bodies. The bottom surface of the third limiting block 62 is in contact with the housing 3, the top surface of the third limiting block 62 is in contact with the bottom surface of the fourth limiting block 63, and the four side surfaces of the first limiting block 52 and the third limiting block 62 are all in the same plane. The side walls of the first limiting block 52 and the third limiting block 62 located in the first limiting space are in contact with the side wall of the main body 41 of the first plug.

[0060] Both the fourth limiting block 63 and the second limiting block 53 are square bodies. The bottom surface of the second limiting block 53 is in contact with the housing 3, the top surface of the second limiting block 53 is in contact with the bottom surface of the fourth limiting block 63, and the four side surfaces of the fourth limiting block 63 and the second limiting block 53 are all in the same plane. The side walls of the fourth limiting block 63 and the second limiting block 53 located in the first limiting space are in contact with the side wall of the main body 41 of the first plug.

[0061] Specifically, the first baffle 51 and the second baffle 61 are arranged in parallel to adapt to the third side surface and the fourth side surface parallel to the main body 41 of the first plug.

[0062] In a possible embodiment, see Figure 2 and Figure 6 , the present application further includes: a first limiting portion for preventing the main body 41 of the first plug from being pulled out of the first limiting space, that is, the first limiting portion prevents the main body 41 of the first plug from being pulled out of the first limiting space through the top opening of the first limiting space.

[0063] Specifically, see Figure 2, the first limiting part includes: a first stop block 8 and a second stop block 9. The first stop block 8 is located within the first limiting space and is fixedly connected to the first limiting block 52. The second stop block 9 is located within the first limiting space and is fixedly connected to the second limiting block 53.

[0064] Further, the first stop block 8 has a first side wall 81 adapted to the transition section 43 of the first plug. In the direction of the first limiting block 52 towards the third limiting block 62, the distance between the first side wall 81 and the first limiting block 52 gradually decreases. The second stop block 9 has a second side wall 91 adapted to the transition section 43 of the first plug. In the direction of the fourth limiting block 63 towards the second limiting block 53, the distance between the second side wall 91 and the fourth limiting block 63 gradually decreases.

[0065] The arrangements of the first side wall 81 and the second side wall 91 utilize the transition section 43 of the first plug. By means of the first side wall 81 and the second side wall 91 that match the plug transition section, the main body 41 of the first plug embedded therein is limited within the first limiting space, thereby ensuring the fastening and anti-loosening of the plug.

[0066] In a possible embodiment, referring to Figures 6 - 9 , the third buckle base 10 of the embodiment of the present invention includes: a third baffle 101, a fifth limiting block 102 provided on the third baffle 101, and a sixth limiting block 103 provided on the third baffle 101. The fourth buckle base 11 includes: a fourth baffle 111, a seventh limiting block 112 provided on the fourth baffle 111, and an eighth limiting block 12 provided on the fourth baffle 111.

[0067] The seventh limiting block 112 is provided between the fifth limiting block 102 and the side surface of the housing 2.

The first groove 1011 and the second groove 1111 combine to form a second limiting space adapted to the main body of the second plug. That is, when the main body of the second plug is inserted into the second limiting space, it is restricted by the second limiting space formed by the third baffle 101 and the fourth baffle 111, so that the main body of the second plug cannot be pulled out of the second limiting space.

[0069] In a possible embodiment, a plurality of second limiting spaces may be provided on the third baffle 101 and the fourth baffle 111, and are respectively adapted to the bodies of second plugs of different models. The number of the second limiting spaces provided is not limited herein.

[0070] Further, referring to Figure 7 , the second fastener 13 includes: a third bolt 131 and a fourth bolt 132. A third bolt hole is provided in the fifth limiting block 102, a fourth bolt hole is provided in the seventh limiting block 112, and a seventh bolt hole is provided on the side surface of the housing 2. The third bolt hole 131, the fourth bolt hole 132, and the seventh bolt hole all extend along a third predetermined straight line direction. The third bolt 131 is sequentially inserted into the third bolt hole 131, the fourth bolt hole 132, and the seventh bolt hole 131, so as to fix the fifth limiting block 102, the seventh limiting block 112, and the side surface of the housing 2 to each other.

[0071] An eighth bolt 132 hole is provided in the sixth limiting block 103, a fifth bolt hole is provided in the eighth limiting block 12, and a sixth bolt hole is provided on the side surface of the housing 2. The eighth bolt hole 132, the fifth bolt hole, and the sixth bolt hole all extend along a fourth predetermined straight line direction. The fourth bolt 132 is sequentially inserted into the eighth bolt hole 132, the fifth bolt hole, and the sixth bolt hole, so as to fix the eighth limiting block 12, the sixth limiting block 103, and the side surface of the housing 2 to each other.

[0072] Specifically, the third predetermined straight line direction is perpendicular to the side surface of the housing 2, so that the third bolt 131 can be screwed into the third bolt hole 131 perpendicular to the side surface of the housing 2. Among them, the third bolt hole 131, the fourth bolt hole 132, and the third bolt hole 131 are all bolt holes. The fourth predetermined straight line direction is perpendicular to the side surface of the housing 2, so that the fourth bolt 132 can be screwed into the sixth bolt hole perpendicular to the side surface of the housing 2. Among them, the fourth bolt hole 132, the fifth bolt hole, and the sixth bolt hole are all bolt holes.

[0073] In a possible embodiment, both the fifth limiting block 102 and the seventh limiting block 112 are square bodies. The bottom surface of the seventh limiting block 112 is attached to the side surface of the housing 2, the top surface of the seventh limiting block 112 is attached to the bottom surface of the eighth limiting block 12, and the four side surfaces of the fifth limiting block 102 and the seventh limiting block 112 are all located on the same plane.

[0075] Further, the third baffle 101 and the fourth baffle 111 are arranged in parallel and attached to each other. The third baffle 101 is located between the seventh limiting block 112 and the eighth limiting block 12, and the fourth baffle 111 is located between the fifth limiting block 102 and the sixth limiting block 103, so that the third buckle seat 10 and the fourth buckle seat 11 form a cuboid after combination.

[0076] In a possible embodiment, referring to Figure 7 and Figure 9 , the present application further includes: a second limiting portion for preventing the main body of the second plug from being pulled out of the second limiting space, that is, the second limiting portion prevents the main body of the second plug from being pulled out of the second limiting space through the top opening of the second limiting space.

[0077] Specifically, referring to the figure and the figure, the second limiting portion includes: a third stop block 14 and a fourth stop block 15. The third stop block 14 and the fourth stop block 15 are respectively fixedly connected to the opposite side walls of the second limiting space, so that the third stop block 14 and the fourth stop block 15 play a role in limiting the transition section of the plug.

[0078] Further, referring to Figure 7 , the third stop block 14 has a third side wall 141 adapted to the transition section of the second plug. In the direction of the fifth limiting block 102 towards the seventh limiting block 112, the distance between the third side wall 141 and the fifth limiting block 102 gradually decreases. The fourth stop block 15 has a fourth side wall 151 adapted to the transition section of the second plug. In the direction of the sixth limiting block 103 towards the eighth limiting block 12, the distance between the fourth side wall 151 and the eighth limiting block 12 gradually decreases.

[0079] Referring to Figure 7 and Figure 9 , the settings of the third side wall 141 and the fourth side wall 151 utilize the transition section of the second plug, and the main body of the second plug embedded therein is limited in the second limiting space through the third side wall 141 and the fourth side wall 151 that match the transition section of the plug, thereby ensuring the fastening and anti-loosening of the plug.

[0080] The present application also provides another embodiment, referring to Figure 11, the housing 2 is a cover plate surrounding the socket 1.

[0081] This application also provides a socket 1 device, which includes: a receiving socket 1 and the plug fastening and loosening prevention mechanism as described above.
