Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector having a guiding anti-collision effect.

A connector is a connection device that electrically connects wires, boards, and other circuit components. It is widely used in various electronic products around our lives, such as notebook computers, mobile phones, and personal digital assistants (PDAs). .

As smart phones and personal portable consumer electronics are gaining popularity among the general public, these personal mobile devices are assembled in order to accommodate more electronic components in a limited space to enhance their functional options. The thickness of the connectors in these electronic products is also required to be thinner to meet the needs of space design, so there is a developer to develop a thin connector, the structure including the lower iron shell, the soft cable and the upper iron The shell replaces the terminal with the contact at the front end of the flexible cable, and omits the design of the original insulating body, so that the purpose of thinning can be effectively achieved.

However, the structure of such a thinned connector does not have a design that guides the foolproof, and it is easy to cause a problem of inserting the wrong direction in actual use. In addition, the thin connector without guiding the foolproof design is easy to collide with the insulative body of the mating connector when the mating connector is inserted. This is a problem that is likely to cause scratching or breakage of the mating connector, so that the conventional thin connector still does not meet the needs of the market today.

Conventional thin connectors are prone to the wrong direction of insertion and the problem of scratching and damage of the mating connector, so they still do not meet the needs of the current market.

The present invention provides an electrical connector, comprising a flexible cable, a housing and two guiding elements, wherein the front end of the flexible cable has a pair of connecting portions, the connecting portion is provided with a plurality of contacts, and the housing is assembled on the flexible cable The front end and the contact portion of the abutting portion are exposed to the housing, and a fixing portion is disposed on each side of the housing, and each guiding component is assembled and fixed on the fixing portion, and the two guiding components are respectively located at the butting portion. On both sides.

The electrical connector provided by the present invention utilizes two additional plastic guiding elements on the corners on both sides of the front end of the housing. The plastic guiding element has the functions of guiding, foolproof and anti-collision. It is easy to solve the problem that the thin connector of the conventional connector is inserted in the wrong direction and the scratch and breakage of the mating connector.

Referring to the first to sixth figures, the electrical connector 1 provided by the present invention comprises a flexible cable 2, a housing 3 and two guiding elements 4.

The front end of the flexible cable 2 has a pair of connecting portions 21, and the mating portion 21 is provided with a plurality of contacts 22, and the reinforcing plate 23 is disposed in front of the flexible cable 2 On the abutting portion 21 of the end, a wing portion 231 is disposed on each side of the reinforcing plate 23, and the wing portion 231 extends and protrudes from both sides of the flexible cable 2. In the present embodiment, the reinforcing plate 23 is disposed on the upper side of the abutting portion 21, but the reinforcing plate 23 may be disposed on the lower side of the abutting portion 21.

The housing 3 is assembled to the front end of the flexible cable 2, and the contacts 22 of the mating portion 21 are exposed to the housing 3 to overlap with a mating connector (not shown). In this embodiment, the housing 3 includes An upper case 31 and a lower case 32 are disposed on the upper and lower sides of the lower case 31 and the lower case 32. The lower case 32 is provided with a bearing surface 321 , and the abutting portion 21 is disposed on the bearing surface 321 . Covering the abutting portion 21, the contacts 22 are exposed to the upper casing 31.

In this embodiment, a fixing portion 33 is disposed on each side of the housing 3, and a lower engaging portion 322 is disposed on each side of the bearing surface 321 of the lower housing 32. The two sides of the upper housing 31 correspond to the lower engaging portion. Each of the 322 is provided with an upper engaging portion 311. The lower engaging portion 322 and the upper engaging portion 311 extend in the same direction and are brought into contact with each other to jointly form the fixing portion 33.

The lower casing 32 extends outwardly from the two sides of the bearing surface 321 to form a protruding portion 323. The lower engaging portion 322 is located in front of the protruding portion 323, and the lower casing 32 is provided with a stopping portion behind each protruding portion 323. 324, an accommodating space 325 is formed between the protruding portion 323 and the lower engaging portion 322 and the stopping portion 324. In addition, a recess 326 is formed between the protruding portion 323 and the front end of the lower shell 32, and the lower engaging portion 322 is located in the recess 326. The end of the protruding portion 323 is further provided with an interference portion 327, and the extension portion 327 is extended. The direction is parallel to the lower engaging portion 322.

In this embodiment, when the abutting portion 21 of the front end of the flexible cable 2 is disposed on the bearing surface 321 of the lower casing 32, the wing portions 231 on both sides of the reinforcing plate 23 are disposed in the accommodating space 325 and are interferingly positioned. Between the lower engaging portion 322 and the retaining portion 324. In addition, a glue layer (not shown) is disposed between the abutting portion 21 and the bearing surface 321 to attach the abutting portion 21 to the bearing surface 321 , so as to stably fix the abutting portion 21 of the front end of the flexible cable 2 to the supporting portion 21 . The housing 3 does not fall off.

The guiding elements 4 are assembled and fixed on the fixing portion 33, and the two guiding members 4 are respectively located on both sides of the abutting portion 21. In the present embodiment, the guiding member 4 is a plastic guiding column made of plastic injection molding, so that the functions of guiding, foolproof and anti-collision can be achieved, and the production cost can be reduced. The guiding member 4 includes a body portion 41 and an extending portion 42 disposed on the body portion 41. The body portion 41 is provided with a recess 411, and the extending portion 42 is provided with a hole 421.

The fixing portion 33 of the housing 3 is inserted and fixed in the recess 411, and the interference portion 327 is inserted and fixed in the hole 421, so that the guiding member 4 is stably fixed to the housing 3 without falling off. Further, the guiding member 4 is assembled and received in the recess 326, and the rear end of the guiding member 4 can abut against the protruding portion 323, so that the force of the guiding member 4 supported by the housing 3 becomes large.

The fixing portion 33 is located on both sides of the abutting portion 21 and extends to the two sides of the connecting points 22, and the two guiding members 4 are respectively located at two sides of the connecting points 22, so as to achieve the purpose of guiding the docking. In this embodiment, a layer of aluminum foil 24 is attached to the flexible cable 2, and the lower shell 32 is connected. The ground shrapnel 328 can be in contact with the aluminum foil 24, so as to prevent electromagnetic wave interference.

In summary, the electrical connector of the present invention utilizes two additional plastic guiding elements on the corners on both sides of the front end of the housing. The plastic guiding element has the functions of guiding, foolproof and anti-collision. In this way, it is possible to solve the problem that the conventional thin connector is likely to be inserted in the wrong direction and cause scratching and damage of the mating connector.

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.
