Description

METHOD FOR MANUFACTURING ELECTRIC CONNECTOR
Technical Field
The present invention relates, in general, to low profile electric-connectors and, more particularly, to a method of manufacturing the electric-connectors, in which a plurality of fusible projections are respectively and integrally provided between a plurality of slots, provided on each of a socket body and a plug body of a connector, while producing the; socket body and the plug body through an injection molding process, and in which each of the plurality of fusible projections is molten by a heat source generated from ultrasonic vibrations (or by high frequency waves , a heat treatment) , so that the molten fusible projection enter the neighboring slots to fasten a terminal to each of the slots, thus improving the reliability of products, preventing defective products from being generated, and reducing the defect and loss of the products undesirably caused while the socket body, the plug body and the terminals are integrally produced through an insert injection molding process.
Background Art
Generally, electric-connectors used in a variety of electronic equipment may have various shapes according to shapes and connecting methods of the electronic equipment, for example, for use in directly connecting the cables to each other or for use in a PCB (printed circuit board) . Typically, the conventional electric-connectors each include a socket and a plug each having a main body which is made of an insulating material and has a plurality of slots. The socket and the plug have a plurality of female terminals and a plurality of male terminals, respectively. The socket and the plug of the conventional electric- connectors are coupled to each other, so that an electric signal is transmitted through the socket and the plug.
The detailed construction of a conventional electric- connector with the terminals is as follows, with reference to FIG. 1.
The conventional electric-connector includes a socket body 10 and a plug body 30. The electric-connector further includes a plurality of first female terminals 20 and a plurality of second male terminals 40 which are provided on the socket body 10 and the plug body 30, respectively. The socket body 10 has a coupling boss 12 which is provided on a central portion of the socket body 10, so that the socket body 10 is coupled to the plug body 30. The socket body 10 is longitudinally divided into two parts by the coupling boss 12. A plurality of first slots 14 are provided on each of the two parts of the socket body 10, divided by the coupling boss 12, at regular intervals. Each of the first female terminals 20 is inserted into each of the plurality of first slots 14.
The plug body 30 has a coupling depression 32 which is provided on a central portion of the plug body 30 to receive the coupling boss 12 of the socket body 10 in the coupling depression 32. A plurality of second slots 34 are provided on each of both sides of the plug body 30. Each of the second male terminals 40 is inserted into each of the plurality of second slots 34.
However, in the above-mentioned conventional electric-connector, the second male terminal 40 is only inserted in each of the second slots 34 of the plug body 30 without any fastening means. Therefore, while the plug body 30 is coupled to or removed from the socket body 10, the second male terminal 40 may be undesirably removed from the second slot 34.
Furthermore, to manufacture the conventional electric-connector with the socket body 10 and the plug body 30, both the first female terminals 20 and the second male terminals 40 are produced into stamp shapes prior to being cut into predetermined lengths. Thereafter, the first female terminals 20 and the second male terminals 40 are respectively inserted into the first and second slots 14 and 34 of the socket body 10 and the plug body 30. The first female terminals 20 and the second male terminals 40 are, thereafter, cut into necessary lengths. However, the above-mentioned conventional method of manufacturing the electric-connectors is problematic in that the first female terminals 20 and the second male terminals 40 may be undesirably removed from the first and second slots 14 and 34 during the process of cutting off unnecessary parts of the first female terminals 20 and the second male terminals 40, respectively.
In an effort to overcome the problems experienced in the above-mentioned conventional electric-connector and the method of manufacturing the same, another conventional method of manufacturing the electric-connectors, in which the first female terminals 20 and the second male terminals 40 each having the stamp shape are respectively placed in molds to form the socket body 10 and the plug body 30 before an insulating resin is injected into each of the molds, was proposed. In this conventional method of manufacturing the electric-connectors, the first female terminals 20 and the second male terminals 40 are respectively fastened to the socket body 10 and the plug body 30. However, the above-mentioned conventional method of manufacturing the electric-connectors is problematic in that the first female terminals 20 or the second male terminals 40 may be leaned toward a direction of injecting the insulating resin in the mold by a high-pressure of the insulating resin irfjected into' the mold. Furthermore, due to the high-pressure of the insulating resin injected into the mold, the mold may be damaged. Thus, the conventional method of manufacturing the electric-connectors may force a user to undesirably change the expensive mold with a new one.
In addition, in the conventional method of manufacturing the,, electric-connectors, a predetermined space is necessary between cavities while injecting the insulating resin into the mold in a state in that the first female terminals 20 or the second male terminals 40 are placed in the mold. Therefore, the material of the first female terminals 20 or the second male terminals 40 is wasted by the predetermined space.
Furthermore, in the conventional manufacturing method using the mold, the arrangement of the first female terminals 20 or the second male terminals 40 may be undesirably unbalanced or deformed. Thus, electric contact of the connector to transmit the signal may be not completely formed, or the electric contact to transmit the signal may be impossible.
