ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The design is related to a telephone transfer double-socket, especially denoting a monotype of telephone socket which may, in addition to providing a similar type of plug for connecting, also provide a double-socket structure for lugging another type of plug. The structure comprises of a male plug which is set in front of the body of the socket to enable the male plug to connect directly with the two socket holes at the rear end of the socket body by means of several guide-joining terminals. Since the design is not only easy to assemble, but is also simple in its component members, its production cost can, therefore, be reduced.
(b) Description of the Prior Art
As is commonly known, a conventional telephone transfer socket usually comprises of such basic components members as male plug, a shell body, a socket body, a circuit board, and several connecting terminals, in which the male plug is usually set at one lateral side of the shell body, with several guide-joining terminals implanted into the male plug, at the end of which a connecting wire pierced through the reverse side of the shell body to connect with the circuit board; after allowing the combination of the connecting terminals in the interior of the socket body with the circuit board, the commination body will jointly cover at the reverse side of the shell body to form a transfer socket. However, the structuring of the above-mentioned telephone transfer socket needs to have the availability of a plurality of spare and component members, and to pass through an assembling process before completion. When the male plug and the socket body differed in shape, the connecting wire will have to be welded in an intersecting manner onto the corresponding position of the circuit board. Such a design indicated a more difficult and complicated assembling process which will relatively increase the production cost. And its telephone transfer socket becomes large in size and occupies much space due to the limitation of their pattern and space. Therefore, it seems not to be very ideal no matter speaking in terms of conveyance, packaging of finished-products or utilization.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide the design of a telephone transfer double-socket, which comprises of a male plug, a socket body, several guide-joining terminals and a stopper plate; the interior of the socket body is integrally formed, with insertion holes made in two different shapes and piercing holes lining side by side; several guide-joining terminals are having two connecting foot at their rear end to allow the several guide-join in terminals to be implanted within the male plug, positioning by means of covering the stopper plate at one lateral side of the male plug to exert pressure; and further cover the bottom end seat of the male plug at the opening of the socket body, and at the same time allow the connecting foot of the several guide-joining terminals to insert into the two insertion holes in the interior of the socket body; in so doing, by means of the guide-joining terminals, the spare and component members for assembling can be simplified to enable assembling to be processed easily, so as to save the cost of production.
The secondary objective of the present invention is to provide the design of a telephone transfer double-socket to enable the extreme end of the guide-joining terminals to extend outward and have a first connecting foot and a second connecting foot; the joining place of the two connecting foot with the terminal body is set in a twisting state in a horizontal plane direction, while the first connecting foot resembled a left or right sideward deviation, and the two ends of the two connecting foot formed a concaved arc shape which, when the two connecting foot are inter-connected with the other telephone plug, will enable it to provide an excellent springing connection to further enable the transmission of signal to be conducted in an extremely stable manner without producing any noise.
