Connector structure

The present invention relates to a connector structure, and more particularly to a connector structure 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, when the thin connector without guiding the foolproof design is inserted into the mating connector, the iron shell easily collides with the insulating body of the mating connector, so that the problem of scratching or breakage of the mating connector is easily caused. Thin connection The device still does not meet the needs of today's market.

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 a connector structure including a lower housing, two guiding members, a flexible cable and an upper housing, wherein the lower housing has a bearing portion and an outwardly extending one side of the self-supporting portion The fitting portion comprises a bottom plate, a top plate and a side plate connecting the bottom plate and the top plate, and a groove is formed between the bottom plate and the side plate and the top plate. Each of the guiding members includes a guiding portion and a base portion connected to the guiding portion, the base portion is fitted into the groove of the fitting portion, and the base portion is provided with an upper interference portion, a lower interference portion, and a left portion. The interference portion and the rear end portion, the upper interference portion and the lower interference portion are vertically disposed, the rear end portion is located on one side opposite to the guiding portion, the left interference portion is located outside the base portion, and the bottom plate interference is fixed to the lower interference The top plate is fixed to the upper interference portion, and the side plate covers the rear end portion. The front end of the flexible cable has a pair of joints, and the joint portion is provided with a plurality of joints, and the joint portion is disposed on the load-bearing portion and located between the two guide members. The upper casing is assembled and fixed on the base portion and located above the flexible cable. The contacts of the abutting portion are exposed to the upper casing, and each of the two sides of the upper casing is provided with a covering portion, and the covering portion includes a bottom wall, a top wall and a side wall connecting the bottom wall and the top wall, the bottom wall is covered on the bottom plate, the top wall is covered on the top plate, and the side wall is interference-fixed to the left interference portion.

The connector structure provided by the present invention utilizes two additional plastic guiding members on both sides of the lower casing and the upper casing, and the plastic guiding member has the functions of guiding, foolproof and anti-collision. It can solve the problem that the conventional thin connector is easy to be inserted in the wrong direction and cause scratching and damage of the mating connector.
