1. Field of the Invention
The present invention relates to a connector, and more particularly, to a receptacle connector.
2. Description of Related Art
With regard to connectors on current electronic devices for connecting with network apparatus, RJ-45 type receptacle connectors are usually used for connecting with corresponding plug connectors. However, with the electronic devices trending toward being low profile, the standard RJ-45 receptacle connectors have apparently become a bottleneck for further thinner design of electronic devices due to the relatively high profile of the standard RJ-45 receptacle connectors.
However, in the construction described above, lowering the receptacle connector's height is constrained by the end of the receptacle terminal that is bent and stopped by the stop portion 122. In order to maintain a desired contact force between the receptacle terminal 110 and the plug terminal 210, the height of the receptacle terminal 110 must be maintained constant. In other words, because the height of the receptacle connector 100 cannot be effectively reduced, the receptacle connector 100 has hindered the development of thinner electronic devices.
Accordingly, the present invention is directed to a receptacle connector having receptacle terminals with reduced height.
The present invention provides a receptacle connector adapted to be electrically connected with a plug connector. The plug connector has a plurality of plug terminals. The receptacle connector includes an insulating body and a plurality of receptacle terminals. The insulating body has a receiving space and a plurality of grooves. The plug connector is adapted to be plugged into the receiving space. The receptacle terminals are disposed within the insulating body. Each of the receptacle terminals includes a base disposed in a corresponding groove, a bent portion connected with the base, a contact portion extending from the bent portion into the receiving space, and an engaging portion extending from the contact portion toward the groove and disposed within the groove. The receptacle terminals correspond to the plug terminals such that the plug terminals press the contact portions, respectively, when the plug connector is plugged into the receiving space.
In view of the foregoing, in the above embodiment of the present invention, the receptacle terminals disposed within the receptacle connector are bent to reduce the overall height of the receptacle connector. In addition, the contact force between the receptacle terminals and the plug terminals is increased when the plug connector is plugged into the receiving space to make sure that the plug connector will not easily become disengaged from the receptacle connector.
Other objectives, features and advantages of the present invention will be further understood from the further technological features disclosed by the embodiments of the present invention wherein there are shown and described preferred embodiments of this invention, simply by way of illustration of modes best suited to carry out the invention.
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” etc., is used with reference to the orientation of the Figure(s) being described. The components of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. On the other hand, the drawings are only schematic and the sizes of components may be exaggerated for clarity. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. Also, it is to be understood that the phraseology and terminology used herein are for the purposes of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. Similarly, the terms “facing,” “faces” and variations thereof herein are used broadly and encompass direct and indirect facing, and “adjacent to” and variations thereof herein are used broadly and encompass directly and indirectly “adjacent to”. Therefore, the description of “A” component facing “B” component herein may contain the situations that “A” component directly faces “B” component or one or more additional components are between “A” component and “B” component. Also, the description of “A” component “adjacent to” “B” component herein may contain the situations that “A” component is directly “adjacent to” “B” component or one or more additional components are between “A” component and “B” component. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
Notably, each receptacle terminal 320 includes a base 322 disposed in a corresponding groove 314, a bent portion 324 connected with the base 322, a contact portion 326 extending from the bent portion 324 into the receiving space 312, and an engaging portion 328 extending from the contact portion 326 toward the corresponding groove 314 and disposed within the corresponding groove 314. The bent portion 324 is substantially U-shaped to provide the receptacle terminals 324 with elasticity. The contact portion 326 is substantially V-shaped to facilitate the contact between the receptacle terminals 320 and the plug terminals 410.
In addition, in the present embodiment, the engaging portion 328 is substantially C-shaped. When the contact portion 326 is pressed by the plug terminal 410, the engaging portion 328 substantially engages against the base 322 and can only slide on the base 322 along the groove 314 due to the structural limitation of the groove 314.
In comparison with the conventional receptacle connector 100 of
Besides, because the contact portion 326 and the engaging portion 328 are formed by bending one end of the receptacle terminal 320, the orthogonal projection of the contact portion 326 on the base 322 falls substantially between the orthogonal projection of the engaging portion 328 on the base 322 and the orthogonal projection of the bent portion 324 on the base 322. When the plug connector 400 is plugged into the receiving space 312, making the plug terminals 410 pressing the contact portions 326 of the receptacle terminals 320, the engaging portions 328 engage against the bases 322. As such, both the engaging portions 328 and bent portions 324 of the receptacle terminals 320 can provide a contact force against the plug terminals 410 to increase the insertion force between the plug connector 400 and the receptacle connector 300, thereby preventing the plug connector 400 from easily becoming disengaged from the receptacle connector 300. The contact portions 326 act as a fulcrum and provide a sufficient contact force in cooperation with the respective engaging portions 328, thus effectively reducing the height of the receptacle terminals 320.
In summary, in the foregoing embodiment of the present invention, the receptacle terminals disposed within the receptacle connector are bent to have a lower height with respective to the terminal bases when compared with the conventional receptacle connector, thus reducing the overall height of the receptacle connector.
In addition, bending of the receptacle terminals also changes the pressing position between the conventional receptacle connector and the plug connector, thus increasing the contact force between the receptacle terminals and the plug terminals. This allows the plug connector to be stably received within the receptacle connector.
