1. Field of the Invention
The present invention is related to an improved press-connecting head structure of a pair of press-connecting pliers for connecting a coaxial terminal, and especially to an improved press-connecting head structure of which the press-connecting head can be used on a BNC type coaxial terminal, an RCA type coaxial terminal and an F type coaxial terminal, or used on F type coaxial terminals of different specifications to press-connect with a coaxial signal line through a simple action of inserting/retracting, thereby the range of application of a pair of press-connecting pliers can be enlarged.
2. Description of the Prior Art
As shown in
A pair of press-connecting pliers used to press connect a coaxial signal line with a coaxial terminal are provided with a fixed block and a press-connecting head; when the coaxial terminal and the tailing end of the coaxial signal line are placed between the fixed block and the press-connecting head of the of press-connecting pliers, handles are pressed to render the press-connecting head to move toward the fixed block, then the coaxial terminal and the coaxial signal line can be press connected and fixed.
However, the coaxial terminals stated above at least include the RCA type coaxial terminals, the BNC type coaxial terminals and the F type coaxial terminals, they are very different by appearance as are the shapes shown in
The press-connecting head of a pair of press-connecting pliers for connecting a coaxial terminal of the present invention basically is composed of an inserting/retracting member and two pressing dies; wherein the inserting/retracting member is assembled with the press-connecting pliers by an inserting mode, while the two pressing dies can be pressing dies with two different specifications suitable for using respectively on a BNC/RCA type coaxial terminal and an F type coaxial terminal, or can be two pressing dies with two different specifications suitable for using respectively on F type coaxial terminals with different specifications.
Thereby, by a simple action of inserting/retracting, different pressing dies of the same press-connecting head can be mutually changed to be exactly aligned with a fixed block, or the press-connecting head can be changed for another one with pressing dies of other specifications. When a user operates the press-connecting pliers to make the entire press-connecting head displace toward the fixed block, he can press connect and fix any kind of the abovementioned coaxial terminals and the coaxial signal line; and then the press-connecting pliers using the press-connecting head structure of the present invention can allow execution of press-connecting operation of the coaxial terminals of different specifications with the coaxial signal line; thereby the range of application of a pair of press-connecting pliers can be enlarged.
The present invention will be apparent in its combination of structure and its entire mode of operation after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
The basic structure of a press-connecting head 40 of a pair of press-connecting pliers for a coaxial terminal of the present invention is shown as in
The inserting/retracting member 41 is assembled on the press-connecting pliers 50 by an inserting mode at a position in juxtaposition with a fixed block 52 of the press-connecting pliers 50, the two pressing dies 42 are provided respectively on corresponding ends of the inserting/retracting member 41, in order that when in use, one of the pressing dies 42 of the press-connecting head 40 exactly is aligned with a fixed block 52 of the press-connecting pliers 50; the press-connecting head 40 and the press-connecting pliers 50 are provided therebetween with connecting means adapted for connecting with each other, the connecting means are provided with engaging means; the orientation of the inserting/retracting member 41 can be changed through inserting and retracting, then another pressing die 42 is exactly aligned with the fixed block 52.
In practicing, such as are shown in
And more, the two pressing dies 42 on the inserting/retracting member 41 can be, as are shown in
Therefore, by a simple action of inserting/retracting, different pressing dies 42 of the same press-connecting head 40 can be mutually changed to be exactly aligned with the fixed block 52, or the press-connecting head 40 can be changed for another one with pressing dies of other specifications; so that the entire press-connecting pliers 50 can be suitable for using on coaxial terminals with different specifications. When the user operates the press-connecting pliers 50 to make the entire press-connecting head 40 displace toward the fixed block 52, he can press connect and fix any kind of the abovementioned coaxial terminals and the coaxial signal line; and then the press-connecting pliers 50 using the press-connecting head structure of the present invention can allow execution of press-connecting operation of the coaxial terminals of different specifications with the coaxial signal line.
One thing is worth mentioning, in the embodiment shown in
Accordingly, the present invention renders the press-connecting head to be changed into a structural form suiting press connecting coaxial terminals, it has a function of enlarging the range of application of a pair of press-connecting pliers; however, the embodiment and description given are only for illustrating the present invention and not for giving any limitation to the scope of the present invention. It will be apparent to those skilled in this art that various equivalent modifications or changes without departing from the spirit of this invention shall also fall within the scope of the appended claims.
