Press, an electrical connector is a connection that electrically connects a circuit board to other circuit components. Therefore, it is widely used in various electronic products around our lives, such as notebook computers, mobile phones, and personal digital assistants (PDAs).

The conventional electrical connector structure includes an insulating body, a plurality of conductive terminals, a plurality of cables, and a metal casing. The insulating body is provided with a plurality of terminal slots. The manufacturing process of the conventional electrical connector is The conductive terminal is assembled in the terminal socket on the insulating body, and then the cable is soldered and fixed on the conductive terminal, and then the metal shell is assembled on the insulating body, so that the conventional electrical connector can be fabricated.

However, such a conventional electrical connector often causes a decrease in production yield due to poor cable soldering at the time of fabrication, thus causing a problem of an increase in manufacturing cost.

The conventional electrical connector is liable to cause a decrease in production yield due to poor soldering of the cable, thus causing a problem of an increase in manufacturing cost.

The present invention provides an electrical connector, comprising an insulative housing, a cable and a metal housing, wherein the insulative housing has a plurality of terminal slots, and the cable includes a plurality of single core wires, and the ends of the single core wires are shaped to form a plurality of The terminal portions are assembled in the terminal slots, and the metal case is assembled to the insulative housing.

The electrical connector provided by the present invention directly cuts the front end of the single core wire of the cable into a terminal portion to replace the previously used conductive terminal, so that the process of soldering the cable to the conductive terminal is not required, since the saving is achieved. The conductive terminals and the soldering process can greatly reduce the manufacturing cost, and also solve the problem of a decrease in production yield and an increase in manufacturing cost due to poor soldering of the prior art.

Referring to the first to fourth figures, the present invention provides an electrical connector 1 comprising an insulative housing 2, a cable 3 and a metal housing 4.

The insulative housing 2 is provided with a bearing surface 21 and a supporting surface 22 opposite to the bearing surface 21. The bearing surface 21 and the supporting surface 22 are vertically disposed oppositely. The bearing surface 21 is provided with a plurality of terminal slots 211 and a horizontal strip portion. 212 , and the horizontal strip portion 212 spans the terminal slots 211 , wherein the horizontal strip portion 212 divides the bearing surface 21 into a front end portion 213 and a rear end portion 214 . A plurality of openings 221 are defined in the support surface 22, and the openings 221 are disposed corresponding to the terminal slots 211. The openings 221 are inserted through the insulative housing 2 and communicate with the corresponding terminal slots. 211, the horizontal strip portion 212 is located directly above the openings 221, so that the insulating body 2 is easy to be injection molded and has a lightweight effect, and has a certain mechanical strength.

The cable 3 includes a plurality of wires 31 separately provided separately from each other, each of the wires 31 including a single core wire 32 and a protective layer 33 covering the single core wire 32. The ends of the single core wire 32 are exposed to the protective layer 33 and are shaped. A terminal portion 321 is formed, and the terminal portion 321 is directly assembled in the terminal slot 211 to replace the conductive terminal (not shown) of the prior art, so that the conventional technology can be used to solder the cable 3 to the conductive terminal. The above process can solve the problem of a decrease in production yield and an increase in manufacturing cost caused by poor soldering of the prior art.

The single core wire 32 is a single metal wire having a circular cross section. As shown in FIG. 5, the end portion is subjected to a punching process to form a flat terminal portion 321 which has a terminal portion 321 as shown in FIG. A contact region 322 and an interference region 323 are located in the terminal slot 211 of the front end portion 213, and the interference region 323 is located in the terminal slot 211 of the rear end portion 214. The front end of the terminal portion 321 is provided with a slope 324. The front end of the terminal slot 211 is provided with a concave wall 215. The inclined surface 324 abuts against the concave wall 215. This prevents the front end of the terminal portion 321 from being exposed to the terminal slot 211. The problem that warpage may occur when the front end of the terminal portion 321 is overlapped with the mating connector (not shown).

It is worth mentioning that the terminal portion 321 is located between the horizontal strip portion 212 and the terminal slot 211, and the terminal portion 321 is protected by the horizontal strip portion 212. It is possible to avoid the problem of upward deflection due to the influence of external force. In addition, a reinforcing portion 216 is further disposed on the edge of the rear end portion 214 adjacent to the protective layer 33 of the cable 3. The rear end of the terminal portion 321 is located between the reinforcing portion 216 and the terminal slot 211. Similarly, the terminal The rear end of the portion 321 is protected by the reinforcing portion 216 to avoid the problem of upward deflection and detachment due to external force.

In this embodiment, the cable 3 is a combination of a plurality of wires 31 separately provided separately from each other, but is not limited thereto. Alternatively, the cable 3 includes a plurality of wires 31 and each wire. 31 is the same as the protective layer 33 including the single core wire 32 and the coated single core wire 32. However, the wires 31 are arranged in parallel and are integrally connected to each other, so that the structure of the integrally formed plurality of wires 31 is formed, as shown in the seventh figure. Shown. Alternatively, the cable 3 is a flexible flat cable (FFC). As shown in the eighth figure, the flexible flat cable includes the single core wires 32 arranged in parallel and covering the wires. An insulating layer 34 of one of the single core wires 32 is exposed at the end of the single core wires 32 to form the terminal portions 321 .

The metal casing 4 is assembled on the insulative housing 2, wherein the metal casing 4 includes an upper casing 41 and a lower casing 42. The upper casing 41 is assembled above the bearing surface 21, and the lower casing 42 is assembled to the supporting surface 22. The upper case 41 and the lower case 42 are in contact with each other to form electrical conduction, and the metal case 4 is used to protect the terminal portion 321 of the cable 3 from electromagnetic waves.

In summary, the electrical connector of the present invention directly punches the front end of the single core wire of the cable into a terminal portion to replace the originally used conductive terminal, so that it is no longer necessary to solder the cable to the conductive terminal, thereby saving The design of the conductive terminals and the soldering process can greatly reduce the manufacturing cost, and also solves the problem of a decrease in production yield and an increase in manufacturing cost due to poor soldering of the prior art.

The above detailed description is intended to illustrate a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalents and modifications may be made without departing from the spirit of the invention. Changes are to be included in the scope of patents covered by this creation.
