Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that prevents the contact from being peeled off.

Since the signal communication between the liquid crystal display and the system host is very large and the frequency is very high, the high-frequency signal transmission system currently installed between the liquid crystal display interface and the system motherboard interface is ultra-high speed (1.4). Gb/s), Low Power Differential Signal (LVDS) receiver with low power consumption and low electromagnetic radiation characteristics as the signal transmission interface of the LCD display interface, and connected to the system host via the transmission line (Transmission Line) The signal transmission interface on the board interface, that is, the connector socket on the system board interface, together form a signal connection, and together form a conventional LVDS signal transmission system.

Generally used in the conventional LVDS signal transmission system, the male connector has a structure including an upper iron shell, an insulating body, a conductive terminal, a flexible cable and a lower iron shell, and the lower iron shell is firstly provided with an insulating body. A conductive terminal is inserted into the insulating body, and the flexible terminal is overlapped on the conductive terminal, and the upper iron shell is disposed on the insulating body. The structure of such a conventional connector is relatively complicated, so the number of manufacturing steps is high and the cost is high. In addition, the size of such a connector is large, and the trend of the current product design is light and short, and it is not meets requirements.

Therefore, some manufacturers have developed a male terminal that directly replaces the conductive terminal with a flexible cable. The connector, so the conductive terminal of the original male connector becomes the golden finger joint of the flexible cable. However, since the golden finger contact of the flexible cable is adhered and fixed to the lower insulating layer by the adhesive, and the front end face of the golden finger contact is substantially a vertical surface, when docked with the mating connector If the force applied too much or too fast, the gold finger contact is often affected by the abutting force impact of the butt terminal, and the peeling is reversed to the lower insulating layer, resulting in the soft cable disposed on the male connector. The structure is damaged and the problem of customer complaints arises.

The contact point at the front end of the flexible cable of the conventional electrical connector is easily affected by the impact of the abutting terminal abutting force in the mating connector, and is reversely peeled off to the lower insulating layer, resulting in structural damage of the flexible cable, which is easy to produce. The problem of customer complaints.

The present invention provides an electrical connector including a first metal housing and a flexible flat transmission component, wherein the first metal housing has a mounting portion, and the flexible flat transmission component is disposed on the mounting portion of the first metal housing, the soft The flat transmission element has a plurality of contacts, and a front end of each contact is provided with a first inclined surface, and the first inclined surface faces away from the mounting portion.

The electrical connector provided by the present invention adopts a beveled surface at the front end of the contact point, and the shape of the inclined surface can reduce the impact of the abutting terminal abutting force, and can effectively avoid the situation that the contact point of the front end of the soft flat transmission component is easily peeled off and folded. In this way, the structural damage of the soft cable of the conventional male connector can be solved and the problem of the customer complaint is generated.
