As shown in fig. 1, 2, 3, 4 and 6, the present embodiment provides a plug 100 (hereinafter referred to as plug 100) for preventing erroneous insertion, which is fitted to a socket 200, and includes: a plug main body 110 including a first plug end 111 along a first direction (for example, an X direction in fig. 2) which is a fitting direction of the plug 100 and the receptacle 200; the plug main body 110 further includes a plug peripheral wall 112 adjacent to the first plug end 111; at least two elastic tongues 120 are provided on the plug outer peripheral wall 112, and the elastic tongues 120 have a locked state in which they abut against the socket 200 to prevent the plug 100 and the socket 200 from moving relatively, and an unlocked state in which they are separated from the socket 200. When the resilient tongue 120 is in the unlocked state, the plug 100 and the receptacle 200 are able to move relative to each other in the first direction.

Illustratively, the plug 100 further includes an external plug connector 130, the external plug connector 130 being configured to connect with an electrical conductor of the connection wire 600. The plug outer connector 130 is an elongated conductor, such as a metal member, extending in a first direction. When the plug outer connector 130 is connected to the plug main body 110, a part of the plug outer connector is located at the plug outer peripheral wall 112, and the other part is located at the first plug end 111. The plug outer connectors 130 may be spaced side-by-side on the plug body 110.

For example, the connection wire 600 may be a twisted pair wire, which includes a metallic conductor (e.g., copper wire) and an insulating protective layer covering the conductor.

The plug main body 110 may be provided therein with an inner cavity and an opening communicating with the inner cavity, a portion of the plug outer connector 130 is located in the inner cavity, and another portion is exposed outside the plug main body 110, and the connection wire 600 is inserted into the inner cavity through the opening and electrically connects the electrical conductor of the connection wire 600 with the plug outer connector 130 located in the inner cavity.

Illustratively, the plug outer connector 130 functions the same as the existing outer conductive connector 430 used in an existing RJ45 plug for connection with twisted pair copper conductors.

The manner of contact between the resilient latch 120 and the receptacle 200 is the same as the manner of contact between the conventional resilient latch 420 provided on the conventional RJ45 plug and the conventional receptacle 500, as shown in fig. 12 and 13.

Typically, the existing plug 400 used in the external network environment is an RJ45 plug, where the RJ45 plug includes an existing plug body 410 and an existing resilient tab 420 disposed on the existing plug body 410, and the existing resilient tab 420 is aligned with the center line of the existing plug body 410, as shown in fig. 13 and 14. Accordingly, the existing socket 500 includes an existing socket body 510 and an existing jack 511 provided at the existing socket body 510, the existing jack 511 being matched with the existing plug 400, as shown in fig. 12. When the existing plug 400 is inserted into the existing jack 511, a gap between the existing plug 400 and the existing jack 511 is small.

Since the plug 100 of the present embodiment is provided with at least two elastic tongues 120, and the existing jack 511 is matched with the existing plug 400 having one existing elastic tongue 420, when the device for the internal network environment, on which the plug 100 of the present embodiment is mounted, is plugged into the existing jack 511, after the plug main body 110 is aligned with the existing jack 511, the at least two elastic tongues 120 cannot enter the existing jack 511, which may block the plugging operation, so that the plug 100 cannot be plugged into the existing jack 511.

According to the plug 100 capable of preventing misplug, at least two elastic clamping tongues 120 are arranged on the outer peripheral wall 112 of the plug, and the plug 100 is blocked when being inserted into the existing jack 511, so that the plug 100 cannot be connected with the existing jack 511 in a jogged mode, equipment, which is provided with the plug 100 and is used for an internal network environment, is prevented from being connected with the existing socket 500 of an external network environment, internal network and external network connection are prevented from the aspect of hardware, and data security is guaranteed.

As shown in fig. 2 and 3, in some embodiments, the resilient latch 120 includes a connection end 121 connected to the plug body 110 and a free end 122 remote from the connection end 121, the free end 122 being capable of being moved closer to or farther from the plug body 110 to switch the resilient latch 120 between the unlocked state and the locked state; a linkage structure 150 is disposed between adjacent elastic tongues 120, and the linkage structure 150 is connected to the free ends 122, so that the free ends 122 of adjacent elastic tongues 120 move synchronously.

Illustratively, the connection terminal 121 protrudes in the first direction from the first plug terminal 111.

The linkage structure 150 is a bar structure, and two ends of the linkage structure are respectively connected to two adjacent elastic tongues 120.

The resilient tongue 120 is disposed obliquely with respect to the plug outer peripheral wall 112 with a gap between the free end 122 and the plug outer peripheral wall 112. When the elastic latch 120 is not subjected to external force, the free end 122 is far away from the plug main body 110, and at this time, if the plug 100 is engaged with the socket 200, the elastic latch 120 is in a locked state. When the free end 122 of the elastic latch 120 approaches the plug main body 110 under external force, the elastic latch 120 is in an unlocked state.

Because the plug 100 is provided with at least two elastic tongues 120, in combination with the above, if it is necessary to pull out the plug 100 that has been fitted with the socket 200 from the socket 200, it is necessary to switch the elastic tongues 120 from the locked state to the unlocked state first, even if the free ends 122 of all the elastic tongues 120 are close to the plug main body 110. If the free end 122 of each elastic latch 120 is manually pressed, the operation is inconvenient. Therefore, in the present embodiment, the free ends 122 of the adjacent elastic tongues 120 can be moved synchronously by the linkage structure 150, that is, at least two free ends 122 can be driven to approach the plug main body 110 synchronously only by pressing the linkage structure 150, so that the operation is convenient.

As shown in fig. 1, 2, 3 and 4, in some embodiments, all of the resilient tabs 120 are disposed on the same side of the plug peripheral wall 112.

Illustratively, the plug peripheral wall 112 includes opposing plug top 1121 and plug bottom 1122, and plug side walls 1123 between the plug top 1121 and the plug bottom 1122, with the plug outer connector 130 extending from the first plug end 111 to the plug bottom 1122, with all of the resilient tabs 120 disposed on the plug top 1121.

All the elastic clamping tongues 120 are arranged on the same side of the outer peripheral wall 112 of the plug, so that the linkage structure 150 is connected with the free ends 122 of different elastic clamping tongues 120, and a user can press the elastic clamping tongues 120 conveniently, and the elastic clamping tongues 120 can be switched from a locking state to an unlocking state conveniently.

As shown in fig. 1 and 3, in some embodiments, all of the free ends 122 of the resilient tabs 120 are integrally connected by the linkage 150.

To achieve synchronous control of all the resilient latches 120, the free ends 122 of all the resilient latches 120 are connected to the same linkage structure 150. Meanwhile, the linkage structure 150 is integrally connected with the free end 122 of the elastic clamping tongue 120, so that all the elastic clamping tongues 120 are integrated, the possibility of breakage of the elastic clamping tongues 120 in the use process is reduced, and the service life of the plug 100 is prolonged.

As shown in fig. 1 and 3, in some embodiments, the resilient catch 120 is provided with two.

Illustratively, the two resilient tabs 120 are symmetrically disposed about a centerline of the plug body 110.

Since the plug 100 is prevented from being inserted into the existing socket 500 by providing two elastic tongues 120 on the plug main body 110, the two elastic tongues 120 are provided in order to reduce the production cost of the plug 100.

As shown in fig. 5, in some embodiments, the plug peripheral wall 112 is provided with a safety protrusion 140.

The safety protrusion 140 is in a strip structure extending along the first direction, and is integrally formed with the plug main body 110, so that the safety protrusion 140 has high strength, and the safety protrusion 140 is prevented from breaking and separating from the plug main body 110 during use.

Illustratively, one end of the safety protrusion 140 is flush with the first plug end 111.

Illustratively, the edges of the safety protrusions 140 are provided with rounded corners to avoid concentration of stress at the edges of the safety protrusions 140, thereby achieving a protective effect on the safety protrusions 140.

Illustratively, the safety protrusion 140 is provided with two and is located on the two plug side walls 1123, respectively, the safety protrusion 140 may have a triangular or trapezoidal cross-sectional shape along a direction parallel to the plug side walls 1123, and the tip or the smaller width end is directed toward the first plug end 111.

Since the safety protrusion 140 protrudes from the plug peripheral wall 112, when the plug 100 is plugged into the existing socket 500, the safety protrusion 140 cannot enter the existing socket 511, and the plugging action is blocked, so that the plug 100 cannot be connected with the existing socket 500, and the safety of the plug 100 is further improved.

Based on the same inventive concept, in combination with the description of the plug 100 for preventing misplug in the above embodiments, the present embodiment provides a socket 200, and the socket 200 has the corresponding technical effects of the plug 100 for preventing misplug in the above embodiments, which are not described herein again.

As shown in fig. 6 and 7, the present embodiment provides a socket 200, which is fitted with the plug 100 according to the above-described respective embodiments in a fitting direction, including: the socket main body 210 is provided with a jack 211 for being embedded with the plug 100, the jack 211 comprises a first sub-jack 2111 and a second sub-jack 2112, the first sub-jack 2111 is matched with the plug main body 110, the second sub-jack 2112 is matched with the elastic clamping tongue 120, and a limiting structure 230 for being abutted with the elastic clamping tongue 120 is arranged in the second sub-jack 2112.

Illustratively, the socket 200 further includes an in-socket connector 220, wherein the in-socket connector 220 is at least partially disposed within the first sub-jack 2111 for electrically connecting with the plug outer connector 130 and the electrical conductors of the connection wires 600, respectively. Note that the in-socket connector 220 is identical to the existing in-socket connector 520 for connection with twisted pair wires provided in the existing socket 500, as shown in fig. 12. The number of the socket inner connectors 220 is matched with the number of the plug outer connectors 130.

Illustratively, the spacing structure 230 may be a protrusion disposed at an aperture of the second sub-receptacle 2112.

When the plug 100 is fitted to the receptacle 200, the plug main body 110 is inserted into the first sub-jack 2111, the elastic tab 120 is inserted into the second sub-jack 2112, and after the plug main body 110 is inserted into the predetermined position of the first sub-jack 2111, the elastic tab 120 abuts against the limiting structure 230 from the inside of the second sub-jack 2112, and the elastic tab 120 is in a locked state. At this time, the plug external connection 130 is electrically connected with the corresponding socket internal connection 220 so that signal transmission between the plug 100 and the socket 200 can be achieved.

As shown in fig. 7, in some embodiments, the receptacle 211 further includes a third sub-receptacle 2113, the third sub-receptacle 2113 mating with the security projection 140 of the plug 100.

When the plug 100 is engaged with the receptacle 200, the safety protrusion 140 is inserted into the third sub-jack 2113.

Based on the same inventive concept, in combination with the descriptions of the plug 100 and the socket 200 for preventing misplug in the above embodiments, the present embodiment provides a connector 300, and the connector 300 has the corresponding technical effects of the plug 100 and the socket 200 for preventing misplug in the above embodiments, which are not described herein.

The present embodiment provides a connector 300, including: the connector body 310 is provided with the plug 100 for preventing erroneous insertion as described in the above-described respective embodiments, or the receptacle 200 as described in the above-described respective embodiments.

As shown in fig. 8, 9, 10, 11 and 12, the connector body 310 may have a rectangular block structure, one end of which is provided with the plug 100 according to the above-mentioned embodiments, the other end of which is provided with the existing socket 500, and the plug outer connector 130 of the plug 100 is electrically connected (e.g., connected by a metal wire) with the existing inner conductive connector 520 of the existing socket 500. Conversion of the existing plug 400 to the plug 100 can be achieved.

As shown in fig. 13, 14, 15, 16 and 17, the socket 200 according to the above embodiments is provided at one end of the connector body 310, the existing plug 400 is provided at the other end, and the in-socket connector 220 of the socket 200 is electrically connected to the existing external conductive connector 430 of the existing plug 400. Conversion of the plug 100 into an existing plug 400 can be accomplished.

As shown in fig. 18, the socket 200 (the structure of which is the same as that shown in fig. 17) according to the above-mentioned embodiments is provided at one end of the connector body 310, the existing socket 500 (the structure of which is the same as that shown in fig. 12) is provided at the other end, and the in-socket connector 220 of the socket 200 is electrically connected to the existing in-socket conductive connector 520 of the existing socket 500. It is possible to electrically connect the existing plug 400 with the plug 100.

As shown in fig. 8 to 17, in some embodiments, the connector body 310 is further provided with a locking assembly 320, and the locking assembly 320 includes a lock housing 321 connected to the connector body 310, and the lock housing 321 is slidably connected with a lock tongue 322.

For example, when the connection body 310 is provided with the plug 100, the free end 122 of the resilient tongue 120 of the plug 100 may be restricted from moving by the locking assembly 320, so that the resilient tongue 120 maintains the locked state.

The lock case 321 is disposed on the same side as the elastic latch 120 of the plug 100, for example, when the elastic latch 120 is disposed on the plug top 1121, the lock case 321 is disposed on the top of the connector body 310. The inside inner chamber that is used for holding spring bolt 322 that is provided with of lock shell 321, the both ends of lock shell 321 along the first direction are provided with an opening respectively, and the opening that lock shell 321 is close to plug 100 can supply the spring bolt to stretch out lock shell 321, and the opening that lock shell 321 kept away from plug 100 is used for inserting the instrument (such as the key) that control spring bolt 322 removed. Illustratively, the tool is provided with a catch and the locking bolt 322 may be provided with a recess (or aperture) through which the tool can be hooked with the locking bolt 322 when inserted into the lock housing 321.

When the locking tongue 322 is located in the inner cavity of the lock case 321, the locking tongue 322 may be pushed by a tool to extend out of the lock case 321, and the extending locking tongue 322 moves between the elastic locking tongue 120 and the plug main body 110 (or between the linkage structure 150 and the plug main body 110), so as to prevent the free end 122 of the elastic locking tongue 120 from approaching the plug main body 110, i.e. prevent the elastic locking tongue 120 from being switched to the unlocking state, as shown in fig. 10 and 11.

After the lock tongue 322 extends out of the lock case 321, the lock tongue 322 may be pulled by a tool to retract into the lock case 321, and at this time, the elastic latch 120 can approach the plug main body 110, i.e., the elastic latch 120 can be switched to the unlocked state, as shown in fig. 8 and 9.

When the connection body 310 is provided with the existing plug 400, the locking assembly 320 functions the same as the existing plug 400 does with respect to the plug 100. The existing elastic latch 420 can be prevented from approaching the existing plug body 410 when the latch 322 is extended out of the lock case 321 as shown in fig. 15 and 16, and the existing elastic latch 420 can be prevented from approaching the existing plug body 410 when the latch 322 is retracted into the lock case 321 as shown in fig. 13 and 14.
