Some embodiments relate to connectors of IT and telecommunications networks, and more particularly to a female connector plug, for example an RJ45 connector, including a lock able to lock or unlock the connector. Such a connector is typically intended to be used in a patch panel, in particular in a high-density patch panel.
Related art connectors include a female plug, fastened to a patch panel or to a wall, and of a male plug, linked to a connection cable such as a patch cable, able to be plugged into the female plug. The female plug includes a plug body intended to be connected by a front face to the male plug. The plug body includes insulation displacement contacts arranged in such a way as to each receive strands contained in a feed cable. The female plug also includes a connection module including several slots each intended to receive an end of a strand of a cable. The connection module is either fixed, or articulated in relation to the plug body or separated from the plug body. When the connection module is articulated or separated, it is arranged so as to be plugged into by a rear face of the plug body or by a lateral face, in such a way as to push each strand against the corresponding insulation displacement contact.
In the case of a related art articulated or separate connection module, the female plug is provided with at least one pressing lever pivotably mounted on the plug body. The lever has an open position, wherein the lever does not constrain the connection module, and a closed position, wherein the lever constrains the connection module in a completely plugged-in position.
In accordance with the related art, in order to maintain the pressing lever in the closed position, the female plug is provided with a locking system. Certain connectors do not allow for a manual locking and may require the use of a tool for the implementing of the locking system. Other connectors have a manual locking system manual, but the manipulation that may be required to lock the connector is laborious due to a reduced gripping zone and sometimes painful due to poor ergonomics of the locking system.
For certain connectors, the unlocking system does not exist, which imposes a destruction of the connector in case of modification of the cabling of the connector, in particular during maintenance operations. The connectors including an unlocking system are designed in such a way as to prevent accidental unlocking, which frequently results in poor unlocking ergonomics.
Some embodiments are directed to addressing or overcoming the aforementioned disadvantages, and are partially directed to a connector including a lock that makes it possible to lock and unlock the connector manually in an ergonomic manner, while still preventing or impeding accidental unlockings.
Some embodiments are directed to a connector-type female plug including a body able to be connected by a front face to a complementary male plug and including a plurality of insulation displacement contacts; a separate connection module including a plurality of slots each intended to receive an end of a strand of a cable and arranged so as to be plugged into by a rear face of the body in such a way as to push each strand against the corresponding insulation displacement contact; and a lever pivotably mounted on the body in such a way as to be able to move between an open position and a closed position attained after lowering the lever in such a way as to grasp a rear face of the module and to push the module into a completely plugged-in position. The female plug includes a lock that is movable according to a sliding movement between a locked position, in which the lock is arranged in such a way as to hold the lever in the closed position, and an unlocked position.
The lock mounted in sliding makes it possible to provide a locking that is ergonomic, intuitive and safe. The unlocking manipulation is the same as the locking manipulation in the opposite direction. The unlocking is therefore also ergonomic and intuitive.
According to a particular embodiment, the sliding mechanism includes at least one slide, such as a slit or a groove, and at least one sliding element, such as a lug or a rod.
According to a particular embodiment, the slide is integral with the lock and the sliding element is integral with the lever. For example, the slide is in a slit in the lock wherein a lug of the lever slides.
According to a particular embodiment, the lock has a general U shape which cooperates with the lever. More precisely, the U-shaped lock cooperates with two lateral faces of the lever and an upper face. The lock then includes two slits, one on each branch of the U and the lever includes two lugs, one on each lateral face. The U shape provides the lock with a wide gripping zone, which contributes to its ergonomics.
According to a particular embodiment, the slide is integral with the lever and the sliding element is integral with the lock. For example, the slide is a slit in the lever wherein a lug of the lock slides.
According to a particular embodiment, the body includes a housing intended for the lock. The lock is arranged in such a way as to be engaged with the housing.
According to a particular embodiment, the module includes a housing intended for the lock. The lock is arranged in such a way as to be engaged with the housing in the locked position.
According to a particular embodiment, the lock is slidably mounted on the body. For example, the body includes a slide wherein a rod slides in such a way that in the locked position of the lock, one end of the rod is engaged with the lever in the closed position.
According to a particular embodiment, the lock is slidably mounted on the module. For example, the module includes a slide wherein a rod slides in such a way that in the locked position of the lock, one end of the rod is engaged with the lever in the closed position.
According to a particular embodiment, the sliding mechanism includes a hard spot between the locked position and the unlocked position.
The term “hard spot” means an element in an articulation, such as a zone of friction or a protrusion, increasing the force that may be required to actuate the articulation between two positions.
The hard spot makes it possible to impede or prevent the accidental passage of a lock from one position to another in the absence of manipulation. It makes it possible in particular to impede or prevent an accidental unlocking.
According to a particular embodiment, the lock includes a deformation zone including the hard spot. The deformation zone allows for a local elastic deformation around the hard spot in such a way as to facilitate the passage of the hard spot. For example, a deformation zone of one or two millimetres thick is created between the slide and a slit parallel to the slide. During the passage of the hard spot, the deformation zone is deformed in such a way that a portion of the deformation zone is displaced in the parallel slit.
According to a particular embodiment, the female plug includes a return mechanism of the lock arranged in such a way as to return the lock to the locked position in the absence of manipulation of the lock.
According to a particular embodiment, the lock is in the locked position when the lever is in the closed position. As such, the manipulation, which includes closing the lever, makes it possible, in the same movement, to lock the lock. For example, in a movement of lowering the lever, an inclined plane pushes back the lock to the unlocked position, then the inclined plane is interrupted and a return mechanism returns the lock to the locked position.
According to a particular embodiment, the female plug includes a display which indicates the locked position or the unlocked position in order to render the manipulation of the lock intuitive.
According to a particular embodiment, the lock includes a non-slip gripping zone in order to impede or prevent the user from slipping during the locking or the unlocking of the lock.
