Title: Telephone transfer double-socket

Description:
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.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As indicated in FIGS. 1 to  3 , the present invention is related to the design of a Telephone Transfer Double Socket, which comprises of a male plug  1 , a socket body  2 , several guide-joining terminal  3 , a stopper plate  4 , etc., in which: 
     For male plug  1 , please refer to FIGS. 1 to  5 , which is made in the type of a British telephone plug, and its extreme end is integrally made to have a bottom end seat  11 , while at the rear end of guiding groove  12  at one of its lateral side a concaved section  13  is formed, and guiding groove  12  can be connected to the interior of bottom end seat  11 ; 
     Socket body  2  is an opening shape of transparent shell body, and its interior is partitioned by rib  21  to form an American type of telephone insertion hole  22  and a British type of telephone insertion hole  23  to allow the two insertion holes to line up side by side, having guiding grooves  221 .  231  which are equally partitioned with guiding groove  12  at one lateral wall of each insertion holes  22 .  23 ; 
     Connecting terminal  3 , as indicated in FIGS. 1 and 3, its body is a long strip body, having its front end protruded to form a guiding terminal head  31  in a direction towards one of its lateral side, with a vertical piece  32  falling at its rear end to enable the upper and lower end of vertical piece  32  to extend outward to form a first connecting foot  33  and the second connecting foot  34 . However, both the two connecting foot are set in a twisting state with vertical piece  32  and formed in a horizontal direction, and the first connecting foot  33  is set in a left or right sideward deviation at a place which it selected, and the end of the two connecting foot formed a concaved arc shape; 
     Stopper plate  4 , which is set corresponding with concaved section  13  of the male plug, is having a hooking piece  41  fixed upside down on each of the front and rear end lateral wall at the two lateral sides to correspond and buckle into concaved section  13  to form stopping and positioning; furthermore, a resistance piece  42  is set on each of the surface of the front and rear end bottom end of stopper plate  4 ; 
     By utilization of the above-mentioned assembling members, please refer to the indication per FIG. 4, and enable the guide-joining terminal head  31  of each guide-joining terminal  3  to insert into each of guiding groove  12  along the bottom end of male plug  1 , to further enable both the first connecting foot  33  and the second connecting foot  34  to be exposed at the outer lateral side of bottom terminal seat  11 , and then enable bottom terminal seat  11  to cover at the opening of socket body  2 ; at the same time enable the first connecting foot  33  to insert into American type of telephone insertion hole  22 , while the second connecting foot  34  is inserted into British type of telephone insertion hole  23 , and connecting foot  33  and  34  are stuck within guide-joining groove  221 .  231  respectively which they are corresponding to; then enable stopper plate  4  to cover onto concaved section  13  of male plug  1  to enable resistance piece  42  to exert a pressure against guide-joining terminal  3  to enable it to be positioned; in so doing, by means of the guide joining directed by guide-joining terminal  3 , the spare and component members for assembling can be simplified to make the assembling process to be conducted more easily, so as to save the production cost. 
     In addition, as the connecting place of the two connecting foot  33 .  34  at the extreme end of guide-joining terminal  3  and the terminal body is set in a bending state to form a horizontal plane direction, and the bending arc shape of its end terminal section enabled the providing of an excellent springing guide joining when the two connecting foot  33 .  34  are inter-inserted with another telephone plug to enable signal transmission to be conducted steadily without producing any noise; and in the process of assembling, just implant connecting foot  33  of guide-joining terminal  3  in an intersecting side by side arrangement manner into guiding groove  12  of male plug  1 . Therefore, when male plug  1  is covering onto socket body  2 , its two connecting foot  33 .  34  can be inserted into guiding grooves  221 .  231  which each of them is corresponding to according to the fixed position to effectively raise its production capacity and reduce the occurrence of defective proportion.
