FIELD OF THE INVENTION
The present invention relates to a waterproof structure of communication connector, and more particularly, to a waterproof structure adapted to be applied to the periphery of a communication connector.
BACKGROUND OF THE INVENTION
It is known that the communication connector is designed and used mainly for connecting with a communication plug and thereby connecting to a communication cable. Thus, for preventing the communication plug or the communication cable from water damage, it is important to have the communication connector to be specifically designed with waterproof capability.
Please refer to FIG. 1A, FIG. 1B and FIG. 2, which are schematic diagrams showing a conventional communication connector. As shown in FIG. 1A, FIG. 1B and FIG. 2, the conventional communicateions connector 10 has a first end 11 and a second end 12, in which the second end 12 is configured with a first connecting member 121, a second connecting member 122, and a third connecting member 123. For waterproofing the asforesaid communication connector, the communication must be configured with a waterproof gasket 116 outside its communication socket 115 that is designed to engage and mate perfectly with in a convex ring formed on the first connecting member 121 that is disposed outside a communication plug 124. Nevertheless, the space remained on the conventional communication connector that can be used for other circuit layout is occupied and thus reduced by those waterproof strictures formed on the communication socket 115 and the communication plug 124.
In addition, the first connecting member 11 is formed with only one communication socket 115 at the side thereof facing toward the second connecting member 12, that is, the first connecting member 11 is a one-way single socket structure that can allow the communication plug 124 to inserted therein only in one direction. In some occasions, for connecting to more than one plugs, it is required to have an additional connecting member with additional communication socket to be disposed at another side of the first connecting member 11 opposite to the side thereof formed with the communication socket 115. However, not only such configuration is inconvenient in usage, but also it is difficult to control the inserting direction of the addition communication socket for the additional connecting member.
SUMMARY OF THE INVENTION
In view of the disadvantages of prior art, the primary object of the present invention is to provide a waterproof structure of communication connector, in that the installation direction of the circuitboard for the waterproof structure is orientated different than that for the conventional communication connectors, resulting that not only the connection strength between the waterproof structure and the circuitboard of a communication connector is improved, but also the strength of support to the circuitboard is increased.
To achieve the above object, the present invention provides a waterproof structure of communication connector, comprising:
- a first frame, composed of a first connecting member and a second connecting member that are disposed opposite to each other, in which the first connecting member is configured with a first end in a manner that the first end is formed with a first groove surrounding the first end;
- a first gasket, made of a waterproofing material while being disposed receiving inside the first groove; and
- at least one second frame, each having a third connecting member that is formed with an accommodation space, while the accommodation space is further formed with an abutment surface;
- wherein, the first connecting member is arranged extending into the accommodation space of the second frame for connecting to the third connecting member, while enabling the first gasket to be sandwiched between the first end and the abutment surface.

However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
