[0033] Beneficial effects of this application:

[0034] The protective shell surrounds the internal clamping part, shielding layer, plug-in part and plug pin, wherein the front end of at least one side of the clamping part is provided with a clamping part, and the clamping part is extended toward the socket as a whole. The side of the clamping part close to the shielding layer is parallel to the side of the shielding layer, and there is a gap between the two, so when the protective shell applies external force to the side of the clamping part away from the shielding layer, the clamping part can approach the shielding layer and deviate relatively. At least one side of the protective shell is provided with a clamping hole matching the position of the clamping part, and the clamping part extends out of the clamping hole at the end away from the shielding layer, and at the same time extends to the inside of the corresponding jack of the socket. When the self-locking plug and socket assembly is clamped and fixed, there is a gap between the side of the clamping part facing away from the shielding layer and the inner wall of the clamping hole close to the socket, and there is no contact. The rear end of the clamping part and the inner wall of the clamping hole facing away from the socket fit together, thereby achieving the purpose of self-locking of the plug and socket. In the process of pulling out the plug, since the protective shell can move forward and backward relative to the clamping part as a whole, and a spring is sleeved on the outer side of the cylindrical structure at the rear end of the clamping part, the spring is close to the socket and contacts the end of the protective shell facing away from the socket. Therefore, when the protective shell is moved away from the socket, the inner wall of the protective shell close to the socket contacts the side of the clamping part facing away from the shielding layer, and applies an external force in the direction of the shielding layer, and the clamping part deviates in the direction of the shielding layer, thereby separating the clamping part from the jack of the socket, achieving the purpose of pulling out the plug, and at the same time, the spring applies an external force in the direction of the socket to the protective shell to ensure that the protective shell can be reset. It should be noted that the protective shell can move forward and backward relative to the snap-in part. During the plugging and unplugging process, the snap-in part, the protective shell and the spring cooperate with each other. The purpose of plugging and unplugging the plug can be achieved by only moving the protective shell forward and backward. There is no need to artificially add external force to the snap-in part itself. While ensuring the connection effect, the use efficiency of the self-locking plug and socket assembly is effectively improved.

[0047] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the self-locking plug and socket assembly includes a plug 100 and a socket 200 that cooperate with each other; the plug 100 includes a protective shell 110, a clamping member 120, a shielding layer 130, a plug connector 140 and a plug pin 150 that are sequentially sleeved from the outside to the inside, and the inner wall of the protective shell 110 is in active contact with the outer side of the clamping member 120; the rear end of the clamping member 120 is a hollow cylindrical structure, extending out of the protective shell 110, and a spring 160 is circumferentially sleeved on the outer side of the rear end of the clamping member 120, and the front side of the spring 160 is in contact with the rear side of the protective shell 110; at least one side of the front end of the clamping member 120 is provided with a clamping portion 121 ; Extending toward the socket 200, the clamping portion 121 can move in a direction perpendicular to the shielding layer; a clamping hole 111 is provided on at least one side of the protective shell 110, and the clamping portion 121 is clamped and fixed in the clamping hole 111. There is a gap between the wedge-shaped surface of the clamping portion 121 and the front inner side of the clamping hole 111, and the rear side surface of the clamping portion 121 is in contact with the rear inner wall of the clamping hole 111. The end of the clamping portion 121 away from the shielding layer 130 extends out of the clamping hole 111 and at the same time extends into the corresponding jack 230 of the socket 200; the number of the clamping portion 121, the clamping hole 111 and the jack 230 matches.

[0048] In this embodiment, the protective shell 110 surrounds the internal clamping part 120, the shielding layer 130, the plug connector 140 and the plug pin 150, wherein the front end of at least one side of the clamping part 120 is provided with a clamping portion 121, and the clamping portion 121 is extended in the direction of the socket 200 as a whole. The clamping portion 121 can move in a direction perpendicular to the shielding layer. Specifically, when the protective shell applies an external force to the side of the clamping portion 121 away from the shielding layer, the clamping portion 121 can approach the shielding layer 130 and deviate relatively. It should also be noted that at least one side of the protective shell 110 is provided with a clamping hole 111 matching the position of the clamping portion 121, and the clamping portion 121 extends out of the clamping hole 111 at the end away from the shielding layer 130, and at the same time extends to the inside of the corresponding plug hole 230 of the socket 200.

[0049] Specifically, during the process of the self-locking plug and socket assembly of the embodiment of the present application being clamped and fixed, there is a gap between the wedge-shaped surface of the clamping portion 121 and the inner wall of the clamping hole 111 on the side close to the socket 200, and there is no contact. The rear end of the clamping portion 121 fits with the inner wall of the clamping hole 111 on the side away from the socket 200, thereby achieving the purpose of self-locking of the plug and socket. In the process of pulling out the plug, since the inner wall of the protective shell 110 is in active contact with the outer side of the clamping piece 120, the protective shell 110 can move forward and backward relative to the clamping piece 120 as a whole, and a spring 160 is sleeved on the outer side of the cylindrical structure at the rear end of the clamping piece 120, and the rear end of the clamping piece 120 is away from the socket 200. A thread is provided at the socket position and is arranged around the clamping piece. The end of the spring 160 close to the socket 200 contacts the end of the protective shell 110 away from the socket. Therefore, when the protective shell 110 is moved away from the socket 200, the inner wall of the protective shell 110 close to the side of the socket 200 contacts the wedge-shaped surface of the clamping portion 121 and applies an external force in the direction of the shielding layer 130. The clamping portion 121 is offset in the direction of the shielding layer 130, thereby separating the clamping portion 121 from the socket 230 of the socket 200 to achieve the purpose of unplugging the plug. At the same time, the spring 160 applies an external force in the direction of the socket 200 to the protective shell 110 to ensure that the protective shell 110 can be reset. It should be noted that the protective shell 110 can move forward and backward relative to the snap-in component 120. During the plugging and unplugging process, the snap-in component 121, the protective shell 110 and the spring 160 cooperate with each other. The purpose of plugging and unplugging the plug can be achieved by only moving the protective shell 110 forward and backward. There is no need to artificially add external force to the snap-in component 120 itself. While ensuring the connection effect, the use efficiency of the self-locking plug and socket assembly is effectively improved.

[0050] It should also be noted that the plug pin 150 is inserted into the connector 140 and surrounded by the shielding layer 130. The full surrounding of the shielding layer 130 can effectively prevent the plug and socket assembly from being interfered by other signals after connection, thereby ensuring the normal transmission of signals or currents.

[0051] In one specific embodiment, a first side plate 122 is provided at one end of the clamping portion 121 facing away from the socket; a first opening 123 and a second opening 124 are respectively provided on both sides of the first side plate 122, and the main bodies of the first opening 123 and the second opening 124 are both rectangular structures; the first side plate 122 is parallel to one side of the shielding layer 130, and there is a gap between the two.

[0052] In this embodiment, a first side plate 122 is provided at one end of the clamping portion 121 facing away from the socket 200. The main body of the first side plate 122 is rectangular in shape, parallel to one side of the shielding layer 130 and having a gap. It should be noted that a first opening 123 and a second opening 124 are respectively formed on the upper and lower sides of the first side plate 122. Both the first opening 123 and the second opening 124 are rectangular openings, and their upper and lower sides are parallel to each other. Specifically, the first side plate 122 is provided at one end of the clamping portion 121 facing away from the socket 200, which can effectively ensure that when the clamping portion 121 is subjected to an external force applied by the protective housing 110, it is easier to move in the direction relative to the shielding layer 130, and the plugging and unplugging efficiency is higher.

[0053] In one specific embodiment, the clamping portion 121 is in a wedge shape and there are two of them; the two clamping portions 121 are oppositely arranged on both sides of the clamping member 120.

[0054] In this embodiment, both of the two clamping portions 121 are in a wedge shape and are correspondingly arranged on both sides of the clamping member 120. There is a gap between the wedge surface of the clamping portion 121 and the inner wall of the front side of the clamping hole 111. When the protective housing is moved backward, the inner wall of the front side of the clamping hole 111 contacts the wedge surface of the clamping portion 121 and applies a force to the clamping portion 121 in the direction approaching the shielding layer 130, whereby the clamping portion is separated from the jack. Specifically, the two clamping portions 121 are symmetrically arranged. Since the number of the clamping holes 111 matches the number of the clamping portions 121, there are two clamping holes 111, and the two clamping portions 121 are correspondingly clamped inside the two clamping holes 111. The method of using two clamping portions 121 can further enhance the stability of the plug and socket assembly after connection and is not easy to loosen and fall off.

[0055] In one specific embodiment, the clamping member 121 further includes a second side plate; the second side plate is oppositely arranged with the first side plate 122. A third opening and a fourth opening are respectively provided on both sides of the second side plate. The main bodies of the third opening and the fourth opening are both rectangular in shape; the second side plate is parallel to the other side of the shielding layer and there is a gap between them.

[0056] In this embodiment, a second side plate is also symmetrically arranged on the side of the clamping member facing away from the first side plate 122. The second side plate has the same structure as the first side plate 122, and a third opening and a fourth opening are respectively provided on the upper and lower sides of the second side plate. Both the third opening and the fourth opening are rectangular in shape. It should be noted that the first side plate 122 and the second side plate are arranged on both sides of the clamping member 120 and cooperate with the clamping portion 121, which is convenient for the plugging and unplugging process to be more smooth. The first side plate 122 and the clamping member 120, and the second side plate and the clamping member are both integrally formed structures, which makes the production process more convenient and saves production costs.

[0057] In one specific embodiment, first protrusions 114 are provided on the top surface and both side surfaces of the protective housing 110; the number of the first protrusions 114 is multiple, and the multiple first protrusions 114 are arranged at parallel intervals along the length direction of the protective housing 110.

[0058] In this embodiment, a plurality of first protrusions 114 are provided on both side surfaces of the protective housing 110, and the plurality of first protrusions 114 are arranged in parallel along the length direction of the protective housing 110, and the intervals between adjacent two first protrusions 114 are the same. It should be noted that by providing the first protrusions 114 on both side surfaces of the protective housing 110, the external friction of the protective housing 110 can be effectively enhanced, making it more labor-saving during the process of plugging and unplugging the plug 100 and the socket 200, improving the use efficiency. At the same time, a plurality of first protrusions are also provided on the top surface of the protective housing along the length direction of the protective housing, and the user can select different positions according to actual needs, making the operation more flexible.

[0059] In one specific embodiment, the protective housing 110 includes an upper shell 112 and a lower shell 113, and the upper shell 112 and the lower shell 113 enclose the protective housing; at positions near the socket on both side plates of the upper shell 112, first grooves are oppositely opened in the direction of the top of the upper shell, and the top edge and the rear edge of the first groove are perpendicular to each other; extension plates 115 are provided on both sides of the lower shell opposite to the first grooves, and the top edge and the rear edge of the extension plate 115 are flush with the top edge and the rear edge of the first groove; the clamping holes 111 extend downward from the top edge of the extension plate 115 towards the bottom of the lower shell.

[0060] In this embodiment, the protective housing is formed by enclosing the upper shell 112 and the lower shell 113, and the contact positions of the upper and lower shells are inserted into each other to form an internally hollow structure. By using the split upper shell 112 and lower shell 113 in cooperation, it can effectively ensure that the process of assembling the plug itself is more convenient. It should also be noted that at positions near the socket 200 on both side edges of the upper shell 112, first grooves are provided from the bottom edge towards the top, and the upper edge and the rear edge of the first groove are perpendicular to each other. Extension plates 115 matching the first grooves are provided on both sides of the lower shell 113 near the socket position, and the top edge and the rear edge of the extension plate 115 are flush with the first groove. The clamping holes 111 are arranged in the extending direction from the top edge of the extension plate towards the bottom of the lower shell, and the clamping holes 111 are in a rectangular structure. By arranging the upper shell 112 and the lower shell 113 in this way, it can ensure that the overall position formed after the upper shell 112 and the lower shell 113 are spliced is flush and the structure is stable, and the production process is also more convenient, effectively improving the production efficiency.

[0061] In one specific embodiment, the rear ends of the upper shell 112 and the lower shell 113 are respectively provided with a first arc-shaped plate 125 and a second arc-shaped plate 126 in the direction away from the socket; the first arc-shaped plate 125 and the second arc-shaped plate 126 surround the position near the socket at the rear end of the clamping member 120.

[0062] In this embodiment, a first arc-shaped plate 125 and a second arc-shaped plate 126 are oppositely arranged at the rear ends of the upper shell 112 and the lower shell 113. The first arc-shaped plate 125 and the second arc-shaped plate 126 enclose a cylindrical hollow accommodation space. The rear end of the clamping member 120 is located inside the accommodation space and extends away from the socket direction to the first arc-shaped plate 125 and the second arc-shaped plate 126. It should be noted that the front end of the spring 160 abuts against the rear end face of one of the arc-shaped plates of the first arc-shaped plate 125 or the second arc-shaped plate 126. By arranging the first arc-shaped plate 125 and the second arc-shaped plate 126, the rear end part of the hollow cylindrical structure of the clamping member 120 is protected from wear.

[0063] In one specific embodiment, a protective sleeve 161 is further provided outside the spring 160; the protective sleeve 161 surrounds the spring 160 as a whole and extends to the first arc-shaped plate 125 and the second arc-shaped plate 126; a second protrusion 162 is provided on the outer side of the protective sleeve 161. The second protrusion 162 is arranged along the length direction of the protective sleeve 161, and the number of the second protrusions 162 is multiple. The multiple second protrusions 162 are circumferentially and spacedly arranged around the outer side of the protective sleeve 161.

[0064] In this embodiment, a protective sleeve 161 is sleeved outside the spring. One end of the protective sleeve 161 close to the socket 200 extends to the first arc-shaped plate 125 and the second arc-shaped plate 126 and is fixedly connected to the first arc-shaped plate 125 and the second arc-shaped plate 126. It should be noted that multiple second protrusions 162 are further provided on the outer side of the protective sleeve 161. The multiple second protrusions 162 are circumferentially and spacedly arranged around the outer side of the protective sleeve 161. There is a gap between the protective sleeve 161 and the cable inserted at the rear end of the plug, which can cooperate with the protective shell to move back and forth. By surrounding and arranging the protective sleeve outside the spring 160, the spring can be effectively protected from wear, its service life can be enhanced, and at the same time, the user can be prevented from being scratched by the spring during the operation process.

[0065] In one specific embodiment, a plug plate 151 is further provided inside the plug-in member 140; the plug pins 150 are inserted inside the plug plate 151, and the number of the plug pins 150 of the plug is multiple. The multiple plug pins 150 of the plug are spaced at intervals along the width direction of the plug plate.

[0066] In this embodiment, a plug plate 151 is further inserted inside the plug-in member 140. The multiple plug pins 150 of the plug are inserted inside the plug plate 151. For the plug arranged in the way that the plug pins 150 of the plug are inserted inside the plug plate 151, the cleaning process is more convenient, and the external use environment is protected from pollution.

[0067] In one specific embodiment, the socket 200 has a hollow internal structure. Inside the socket 200 on the side facing away from the plug 100, a fixing portion 210 is provided, and a fixing groove 211 is formed inside the fixing portion 210. The plug board is inserted into the fixing groove 211. At one end of the fixing portion 210 facing away from the plug, socket pins 220 are inserted. A plurality of socket pins 220 are evenly spaced along the end face of the fixing portion and distributed in two rows.

[0068] In this embodiment, the plug board 151 is inserted into the fixing groove 211 provided inside the fixing portion to fix the plug and the socket. At the same time, a plurality of socket pins 220 are also inserted on the end face of the fixing portion 210 at one end facing away from the plug. It should be noted that the plurality of socket pins 220 are evenly spaced along the end face of the fixing portion 210 and distributed in two rows, and extend in the direction of the plug. Specifically, the two rows of socket pins 220 respectively contract towards the plug board 151 to form a locking structure of the socket pins 220 to lock and fix the plug pins, further improving the stability of the self-locking plug and socket assembly.
