Description

Field of invention:

The present invention relates to adapter for releasibly engaging electrical connector plugs. Specifically, this invention relates to a connector adapter for Registered Jack (RJ) type connector plugs, and more specifically for a RJ45 type connector plug.

Background of the invention:

Electrical connectors that are commonly used in telecommunication systems provide an interface between successive runs of cables and/or between cables and electronic devices of the system. An accessory may communicate with a portable electronic device using a connector system. This connector system may include a plug connector that is associated with the accessory and a receptacle connector that is associated with the portable electronic device. RJ modular connectors have been widely used in telecommunication systems ever since they were first created and adopted by the industry. An RJ45 modular connector, which includes a total of eight terminals has been widely used in the network systems.
A user may connect the plug connector of the accessory to the receptacle connector of the portable electronic device thereby forming physical and electrical connections between the contacts of each of the connectors. The host device and the accessory may then exchange data and/or send/receive power using the connectors. Often, the adapter defines the interface between an outside box connector and an inside box connector.
The adapters for anchoring the RJ type connector plugs known in the art fail to provide the adequate play to the connectors. One outstanding drawback of the existing connector adapter is illustrated in figure 1 of the accompanying drawings. As seen in the figure, a single flat is provided in the adapter at the protrusion for receiving the connection plug. The single flat constitute both the snap and bearing area. Due to this the connector anchored in the adapter will be having excessive play/loose causing inconvenience to the user.
Further, some of the problems in existing adapter include:

No dedicated support features for the connector plug;
Connector are pushed inside the wall-box while inserting plug;
Loose/play in connector leads to the tiling of connector and resulting to shutter stuck-up.

With a view therefore to the problem associated with the conventional anchoring/fixing techniques of connector adapter system the inventors felt to need to develop a novel connector adapter for releasably attach a connector plug, particularly for a RJ45 type of connector plug anchored in said connector adapter and providing a connector bearing surface in conjunction with cantilever snap to anchor said connector plug into said adapter which restricts any loose movement of the connector plug. With the top wall of the adapter provided with stopper ribs to locate the insertion of said connector plug and bottom wall is provided with extended cantilever which at insertion of connector plug resiliently bend and receive said connector plug. Thus the invented adapter provides a safe and convenient modular solution to the problem addressed.

Summary of the invention:

Present invention focuses of robust fixation of connector while ensuring annular clearance between the connector plug and centre plate opening. Accordingly the present invention provides an adapter for releasably engaging a connector plug, said adapter comprising:

connector bearing surfaces, a cantilever snap, a first surface defining a top wall, a second surface defining a bottom wall and two opposing side walls, said walls defining an opening for said connector plug,

According to a most preferred embodiment of the invention said top wall is provided with

stopper ribs extending from said top wall to locate the insertion of said connector plug; and
pair of guiding protrusions to receive the connector plug in a guided manner;

According to the most preferred embodiment said connector bearing surfaces are disposed in both side of said cantilever snap to anchor said connector plug into said adapter.

Detailed description of the invention:

With reference to figures 2-11 of the accompanying drawings, an adapter (100) for releasably engaging a connector plug (200) is disclosed herein. The adapter, in general is engaged to a fixing frame (30) on a wall box, or may be installed in power racks. Said adapter (100) is used to anchor the connector plug, here a Registered Jack (RJ)-type connector plug (200), more specifically a RJ45 connector plug. As discussed, said adapter provides a housing for said connector plug (200).
The adapter (100) as illustrated in figures 2-5 comprises a first surface a second surface and two opposing side walls (108). In a particular arrangement of the adapter (100) as depicted in figure 5, the first surface can be considered to be a top wall (105) and the second surface can be considered as bottom wall (106). The side surfaces, as seen in the figure have matching planner profile with the connector plug (200) to be housed in said adapter (100). The top wall (105) and the bottom wall (106) are provided with fixing structures to anchor said connector plug (200). The fixing structures of the top wall (105) and the bottom wall (106) functions in conjunction with each other providing a robust fixation to the connector plug (200).
The fixing structures of top wall (105) of the adapter (100) is depicted in figure 4 of the accompanying drawings. The top wall (105) is provided with feature of stopper ribs and the feature of guiding protrusions (107). The stopper rib(s) (104) could be a single extension from the top wall (105). Alternatively, two extensions can be provided that protrude from the top wall (105) (Fig. 5). The extended ends of the ribs forms a planner surface which enables the stopper feature. The planner surface is of matching profile with the clearance available at the top surface of RJ45 connector plug (200) as illustrated in figure 5 of the accompanying drawings.
The fixing structure of the bottom wall (106) of the adapter (100) is shown in figure 3 of the accompanying drawings. The bottom wall (106) with feature of extended cantilever portion (103). The extension of the cantilever is parallel to the plane surface of the stopper ribs (104) of said top wall (105). The fixed end is attached to said bottom wall (106) such that upon action of any positive force the extended end bends resiliently. As seen figures 3 and 5, the extended end (103) has a slope for the ease of anchoring the connector plug (200).
In the figures 2, 8 and 9 the feature of connector bearing surface (101) and cantilever snap (102) feature are depicted. These two feature diligently solves the problems in the existing adapters (100') for connector plug (200) shown in figure 1 (a&b). The single flat constitute both the snap (105') and bearing area (106'). In the invented adapter (100), the single flat wall for anchoring the connector plug (200) has been removed and instead an adapter bearing surface (101) and cantilever snap (102) feature is introduced.
The anchoring of the connector plug within the adapter (100) is illustrated in figure 8 with the arrow signs directing the direction of insertion of the connector plug (200). Upon applying positive pressure with the connector plug, the extended cantilever portion (103) of the bottom wall (106) the stopper ribs (104) feature of the top wall (105) receives the connector plug (200).
