Detailed Description

As shown in fig. 1 to 11, the misplug prevention network connector provided in the present embodiment includes a network plug 1 and a socket 2. The network plug 1 comprises a plug body 11, an elastic wing buckle 12 and two convex angles 13, wherein a groove 110 extending to the insertion front end of the plug body 11 is formed in at least one side wall of the plug body 11, the elastic wing buckle 12 is connected to one surface of the plug body 11, the two convex angles 13 are symmetrically arranged at the front end of the elastic wing buckle 12 or the front end of the plug body 11, and the two convex angles 13 are protruded from the plug body 11 along the insertion direction. The socket 2 comprises a socket body 21 and a partition plate 22, wherein the socket body 21 is provided with a socket 20, at least one side wall of the opening of the socket 20 is provided with a transverse blocking part 211 which extends towards the width direction of the socket 20 to partially reduce the width of the socket, and the transverse blocking part 211 is matched with a groove 110 on the side wall of the plug body 11; the partition plate 22 divides the socket 20 on the socket body 21 into a main accommodating cavity 201 and a lobe accommodating cavity 202 along the insertion direction, two insertion holes 220 distributed opposite to the two lobes 13 are formed in the partition plate 22, the plug body 11 and the elastic wing buckle 12 are accommodated in the main accommodating cavity 201, and the two lobes 13 pass through the two insertion holes 220 on the partition plate 22 and extend into the lobe accommodating cavity 202.

In this embodiment, as shown in fig. 7 and 9, the network plug 1 further includes a plurality of metal contacts 14 embedded in the other surface of the plug body 11 and extending to the insertion front end, and the plug body 11 also has a wire hole 111 into which the twisted pair wire is inserted. Correspondingly, the inner peripheral wall of the socket 20 in the socket 2 is provided with elastic pins 23 electrically intercepted by the plurality of metal contact pieces 14. In the anti-misplug network connector provided in the present embodiment, the number of the metal contacts 14 in the plug main body 11, the number of the wire holes 111 into which the twisted pair wires are inserted, and the number of the elastic pins 23 on the socket 2 are the same as those of the existing standard communication sockets (such as RJ 45), which ensures that the anti-misplug network connector provided in the present embodiment keeps consistent with the existing standard RJ45 connector in terms of communication manner. However, in the plug structure, a lateral blocking portion 211 extending in the socket width direction (K direction in fig. 8 and 11) is formed at the socket opening at the side wall of the socket body 21. The provision of the lateral stops 211 shortens the width of the socket 20 thereat, in fig. 11, D1 being the socket width at the lateral stops 211, D2 being the width of other areas on the socket for receiving the plug body, D1 being smaller than D2. For the plug on the existing RJ45 standard connector, the blocking of the transverse blocking portion 211 makes it impossible to insert the plug into the socket 2 of the anti-misplug network connector provided in the present embodiment, so that the insertion of the existing standard network plug widely used in the public network is effectively avoided.

Furthermore, for the receptacle 2, the provision of two insertion holes 220 in the bulkhead 22 for insertion of two lobes 13 in the mating network plug 1 also effectively avoids network plug insertion on non-standard connectors based on the same concept but differing in lobe positions or numbers, as in the non-standard network plug with only a single lobe shown in embodiment two. In addition, the symmetrically arranged convex corners 13 are attractive in appearance, and the design of the die size during forming is more accurate and convenient. The arrangement of the transverse blocking portion 211, the partition 22 and the insertion hole 220 on the partition makes the socket 2 in the misplug-preventing network connector provided in the present embodiment effectively avoid the insertion of standard network plugs and simultaneously effectively avoid the insertion of other types of non-standard network plugs. Likewise, the provision of the lobes 13 on the network plug 1 also prevents it from being inserted into existing standard receptacles and receptacles on non-standard connectors having different numbers or positions of insertion holes in the bulkhead. Therefore, when the misplug-preventing network connector provided by the embodiment is applied to a private network (such as an intranet of an enterprise and public institution), separation of the private network and the public network can be realized from physical connection, so that the security of the network is improved, and the wiring difficulty and the error rate are greatly reduced.

Although this embodiment is described by taking a standard connector such as RJ45 as an example. However, the present utility model is not limited in any way thereto. For network connectors (such as RJ 11) with other communication modes, the design of the misplug-proof network connector can be realized by arranging a transverse blocking part, a baffle plate and an insertion hole on a socket of a standard connector based on the same conception.

In the present embodiment, the plug body 11 has grooves 110 extending to the insertion front end thereof on both side walls. On the socket body, both side walls are formed with lateral blocking portions 211 protruding in the socket width direction to partially reduce the socket width at the socket opening. However, the present utility model is not limited in any way thereto. In other embodiments, only one side wall of the socket body may be provided with a transverse blocking portion at the opening of the socket; correspondingly, the plug body is provided with a groove on only one side wall.

In this embodiment, as shown in fig. 5, two convex corners 13 are symmetrically disposed at the front end of the elastic wing 12 along the transverse direction (the transverse direction refers to the width direction of the socket on the socket body). However, the present utility model is not limited in any way thereto. In other embodiments, the two convex corners may be disposed at the front end of the plug body symmetrically along the transverse direction or symmetrically along the longitudinal direction. Specifically, in the present embodiment, the elastic wing buckle 12 includes a connecting portion 121 connected to the plug body 11, two protruding corners 13 are symmetrically disposed at the front end of the connecting portion 121 along the lateral direction, and a clamping groove 130 is formed between the two protruding corners 13 and the connecting portion. When the network plug 1 is inserted into the socket 2, the bottom of the clamping groove 130 abuts against and is limited in the area between the two insertion holes 220 on the partition 22. The limit of the bottom of the clamping groove 130 effectively avoids the front ends of the two convex angles 13 from being damaged due to over-insertion when the network plug 1 is assembled. Further, in the present embodiment, the front end of each of the lobes 13 is provided with an inclined or rounded guide surface, which enhances the strength of the edge of the lobe 13 and reduces interference with the receptacle 2 during insertion. In this embodiment, each lobe 13 has an equal cross-sectional area in the insertion direction. However, the present utility model is not limited in any way thereto. In other embodiments, when two lobes are directly connected to the front end of the plug body, the lobes may be configured to have a greater cross-street area at the connection to enhance the connection strength; at this time, the cross-sectional area of each lobe in the insertion direction will gradually decrease.

In this embodiment, the elastic buckle 12 further includes an elastic portion 122, a wing portion 123 and a hand-held portion 124 connected in sequence, the elastic portion 122 is connected to the connecting portion 121, the thickness of the wing portion 123 is greater than that of the elastic portion 122, the hand-held portion 124 is connected to the rear end of the wing portion 123, the width of the hand-held portion 124 is smaller than that of the wing portion 123, and two limiting steps 120 are formed at the connection portion of the two. As shown in fig. 10, two front end blocking portions 212 are formed at the opening of the socket on the socket body 21, and in the connected state, the two front end blocking portions 212 lock the two limiting steps 120 on the elastic wing buckle in the socket 20. When the network plug 1 and the socket 2 are separated, the elastic wing 12 is compressed to separate the two limiting steps 120 from the two front end blocking parts 212, and then the network plug 1 is pulled out by applying force.

In the misplug preventing network connector provided in the present embodiment, the other surface of the plug body 11 is provided with a contact slot 112 extending to the front end of the plug, and a plurality of metal contacts 14 are accommodated in the contact slot 112. In order to avoid the influence of components such as the partition plate 22 in the socket body 21 on the metal contact 14 caused by excessive acting force in the plugging process, the front end of the plug body 11 is provided with a contact protection part 113 protruding forward, when the network plug 1 is plugged into the socket 2, even if the network plug is excessively plugged due to excessive acting force, the contact protection part 113 can preferentially touch the socket body 21 or the partition plate 22, so that the protection of the metal contact 14 is realized.

On the other hand, the present embodiment also provides a network connection device, as shown in fig. 12, which includes a connection line 100 and two of the above-mentioned misplug preventing network connectors 200. The network plugs 1,1 'on the two misplug-preventing network connectors 200 are respectively arranged at two ends of the connecting wire 100, and the corresponding two sockets 2,2' are arranged on the communication equipment or the computer.

Alternatively, in other embodiments, the network connection device includes a connection line and two of the above-mentioned anti-misplug network connectors. One of the network plugs of the misplug-preventing network connector is connected with the connecting wire, and the socket corresponding to the network plug is arranged on the communication equipment or the computer. In another anti-misplug network connector, the socket is connected to the other end of the connecting wire, and the corresponding network plug is connected to the connecting wire of another network connecting device or other connecting wires.

Alternatively, in other embodiments, as shown in fig. 13, the network connection device may also include only one anti-misplug network connector, where the socket 2 (or the network plug 1) on the network jack assembly is disposed at one end of the connection line 100, and the corresponding network plug 1 (socket 2) is disposed at an external facility. The other end of the connection wire 100 may be connected to a standard network plug (e.g., a standard RJ45 network plug), a standard jack, or other network plug with a lock (not shown).

However, the present utility model is not limited in any way thereto.

Also, in this embodiment, the two lateral blocking portions 211, the convex angle 13 'and the insertion holes 220' in the partition board are arranged so that the socket 2 can effectively block the insertion of the existing standard network plug and simultaneously block the insertion of the non-standard network plug according to the embodiment; likewise, the network plug 1 provided in this embodiment cannot be plugged into a standard socket and a non-standard socket of the type shown in the first embodiment; thereby realizing special private network.
