This application claims the benefit of Chinese Patent Application No. 202011296571.6 filed on Nov. 18, 2020 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
The present invention relates to an adapter for use with an electrical connector assembly, and more particularly, to adapter for use with an RJ45 socket connector and plug connector, by way of example.
In the prior art, both RJ45 plug connectors and RJ45 socket connectors are standardized connector products. Generally, a housing of RJ45 plug connector includes an elastic locking structure and an unlocking pressing part for actuating the elastic locking structure. When the RJ45 plug connector and the RJ45 socket connector are mated together, the elastic locking structure on the RJ45 plug connector is oriented in a locked position in which the elastic locking structure is engaged with the RJ45 socket connector, thus locking the RJ45 plug connector and the RJ45 socket connector together. Therefore, when the RJ45 plug connector needs to be removed from the RJ45 socket connector, the elastic locking structure must be biased or pressed into an unlocked position in which the elastic locking structure is separated from the RJ45 socket connector by the unlocking pressing part, after which the RJ45 plug connector can be removed. However, as the elastic locking structure needs to be pressed to the unlocked position by the unlocking pressing part, a quick unplugging operation between the RJ45 plug connector and the RJ45 socket connector cannot be realized.
According to an embodiment of the present disclosure, a plug connector assembly comprises a plug connector having an elastic locking structure for locking to a socket connector. The elastic locking structure movable between a locking position engaged with the socket connector, and an unlocking position separated from the socket connector. An adapter of the assembly includes a pressing structure and a pull stop structure. The plug connector is received within the adapter for mating with the socket connector slidably inserted into the adapter. When the plug connector is received within the adapter, the pressing structure presses and holds the elastic locking structure in the unlocking position, and the pull stop structure abuts the elastic locking structure for preventing the plug connector from being pulled out of the adapter.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
According to an embodiment of the present disclosure, a plug connector assembly comprises a plug connector having an elastic locking structure adapted to be locked to a socket connector, and an adapter having a pressing structure and a pull stop structure. The plug connector and the socket connector are adapted to be inserted into the adapter for mating the plug connector to the socket connector. The elastic locking structure is adapted to be moved between a locking position engaged with the socket connector and an unlocking position separated from the socket connector. When the plug connector is assembled in the adapter, the pressing structure presses and holds the elastic locking structure in the unlocking position, and the pull stop structure abuts the elastic locking structure to prevent the plug connector from being pulled out of the adapter.
According to another embodiment of the present disclosure, a connector assembly comprises the above plug connector assembly and a socket connector adapted to be inserted into the adapter of the plug connector assembly to mate with the plug connector arranged within the adapter. The adapter is adapted to be slidably inserted over, or otherwise slidably connected to, the socket connector in a friction-fit manner and without any positive locking engagement. IN this way, quick and efficient disconnection of the plug connector (and adapter) from the socket connector via the application of force in a single direction is realized.
According to another embodiment of the present disclosure, an adapter for mating a plug connector and a socket connector is provided. The plug connector is adapted to be assembled in or inserted into the adapter to mate with the socket connector inserted into the adapter. The plug connector comprises an elastic locking structure adapted to be moved between a locking position in which the elastic locking structure is engaged with the socket connector, and an unlocking position in which the elastic locking structure is separated from the socket connector. The adapter has a pressing structure and a pull stop structure. When the plug connector is installed within the adapter, the pressing structure presses and holds the elastic locking structure in the unlocking position, and the pull stop structure engages with the elastic locking structure to prevent the plug connector from being pulled out of the adapter.
In an exemplary embodiment, the adapter 30 has a pressing structure 313, 323 and a pull stop structure 312. As the plug connector 10 is assembled in the adapter 30, the pressing structure 313, 323 presses and holds the elastic locking structure 120, 121 in the unlocking position, and the pull stop structure 312 abuts an opposing surface the elastic locking structure 120, 121 in a removal direction for preventing the plug connector from being pulled out of the adapter. Therefore, as the plug connector 10 is assembled or inserted into the adapter 30, the plug connector cannot be pulled out from the adapter by pulling the cable 101 at the rear end of the plug connector.
According to an embodiment, the elastic locking structure 120, 121 comprises an elastic arm 120 provided on a housing 110 of the plug connector 10, and a pair of locking protrusions 121 provided on both sides of the elastic arm. When the elastic arm 120 is in a release state in which it is not pressed down, the pair of locking protrusions 121 are in the locking position. When the elastic arm 120 is in a pressed downwardly, the pair of locking protrusions 121 are in the unlocking position.
Still referring to
The pressing structure 313, 323 comprises a cross beam 313 connected between the pair of pillars 312, and the cross beam 313 is adapted to press down the elastic arm 120 so that the pair of locking protrusions 121 are in the unlocking position. In an embodiment, the pressing structure 313, 323 further comprises a pressing part 323 formed on the inner wall of the outer housing 32, the pressing part is adapted to press down the elastic arm 120 so that the pair of locking protrusions 121 are in the unlocking position.
It should be understood that the elastic arm 120 can be pressed down simultaneously by the cross beam 313 and the pressing part 323, or only by one of the cross beam or the pressing part. Therefore, it is possible that only the cross beam 313 is provided without the pressing part 323. Alternatively, it is also possible that only the pressing portion 323 is provided without the cross beam 313.
In one embodiment, an elastic latching structure 314, 314a, 314b is respectively provided on two outer side walls of the inner housing 31. When the inner housing 31 is assembled in the outer housing 32, the elastic latching structure 314, 314a, 314b is engaged with the inner wall of the outer housing 32, so as to lock the inner housing 31 to the outer housing 32. The elastic latching structure 314, 314a, 314b comprises an elastic cantilever 314 and a latching protrusion 314a formed on the outside of the elastic cantilever. Two locking steps 322a are respectively formed on the two inner side walls of the outer housing 32. When the inner housing 31 is assembled in the outer housing 32, the latching protrusion 314a is engaged with the locking step 322a, so as to lock the inner housing to the outer housing.
According to one embodiment, when the inner housing 31 is assembled in the outer housing 32, a free end 314b of the elastic cantilever 314 is located outside the outer housing, such that the latching protrusion 314a is capable of being separated from the locking step 322a by pressing the free end.
As shown in
The bottom of the inner housing 31 is opened, and the plug connector 10 is adapted to be installed into the inner housing 31 from a bottom opening of the inner housing. After the plug connector 10 is assembled into the inner housing 31, the inner housing and the plug connector assembled in the inner housing are inserted into the outer housing 32 together.
According to one an embodiment, the plug connector is an RJ45 plug connector, and the socket connector is an RJ45 socket connector. As both RJ45 plug connector and RJ45 socket connector are standardized connectors, the present application will not describe their structure in detail.
A locking feature 21 is formed on an inner wall of a housing of the socket connector 20. The locking feature 21 is adapted to engage with the elastic locking structure 120, 121 on the plug connector 10. When the socket connector 20 is inserted into the adapter 30 and mated with the plug connector 10, the elastic locking structure 120, 121 is in the unlocking position in which the elastic locking structure is separated from the locking feature 21, so as to allow the socket connector to be pulled out from the adapter via the application of a force in only a single direction. In this way, an efficient and quick plugging operation between the plug connector 10 and the socket connector 20 can be realized.
