Electrical connector

This creation is about the general-purpose serial bus connector, especially the structure designer of the USB type-C electrical connector.

Universal Serial Bus (USB) connector is one of the commonly used connector types. It is developed by USB Associationer Forum Inc. (USB-IF) and has experienced USB1.0 so far. With the development of multiple versions such as USB2.0 and USB3.0, the USB type-C transmission protocol with higher transmission speed is now being developed. The USB type-C focuses on the current trend of thin and light product design, and the overall shape is miniaturized. Designed and easy to carry, in order to meet the application needs of mobile products, and no longer have the difference between the front and the back. In the past, when users had to insert the corresponding slots on the computer, they often often had inconveniences due to unclear front and back. This situation will not happen in the future to make it easier for users to get started.

At present, the universal serial bus bar connector mainly has a pair of sockets on the insulating body of the plastic material, and the socket is provided with a plurality of conductive terminals, which are arranged in a flat manner or in a zig-zag manner. Or the surface of the insulating body is arranged by changing the spacing between the terminals, and the outer casing of the insulating body is covered with a metal material, and the metal shell is arranged to strengthen the connector structure, and is not easily deformed when subjected to an external force. However, the housing of the structural metal material is only wrapped around the circumferential side of the slot of the insulating body, and the connector body is actively reduced and the overall function is extremely large. Under the trend of the trend, the components are constantly required to reduce the size of each part, thus causing the components of the connector to be brittle and thin, especially when the miniaturized connector male seat and the female seat are butted together, the positively applied insulating body There is no protection device at the edge of the slot. If the force is improper or the angle of the butt joint is skewed, the connector may be cracked or damaged at the edge of the connector.

Since the universal serial bus connector is the transmission interface between electronic devices, it has to be inserted and removed thousands of times during its service life. If the connector has no stable structure and proper protection design, the connector will be greatly reduced. The overall plug-in resistance is loose, detached and damaged between the insulating body and the housing after multiple insertions and removals. If the conductive terminals for transmitting signals are disposed on the peripheral side of the insulating body, the transmission signal will be seriously affected. stability. In the increasingly complex circuit layout and the increasing functionality, the stability of the product structure and the ease of use are also urgent. If there are suitable and practical components, the following positive benefits can be achieved:

First, it can reduce the damage of equipment caused by user's negligence.

Second, simplify the production process, and thus reduce production costs.

Third, it is convenient for consumers to use.

Fourth, maintain signal stability.

Therefore, the main purpose of this creation is to be a connector that can be mounted on a circuit board for high-speed signal transmission, and has the advantages of high strength and plugging resistance, so that it can be applied to various electronic devices.

In order to achieve the above object, an electrical connector is provided, which at least includes an insulative housing having slots for other connectors to be inserted, and a plurality of conductive terminals are respectively disposed on two sides of the slot, and the insulating body is covered with a shielding shell Body, the shielding shell is bent back inward at one end leading edge The engaging portion is configured to cover the slot edge and fix the recessed portion that is engaged with the inner edge of the slot and disposed inwardly.

1 is a perspective exploded view of the first embodiment of the present invention, and together with other drawings, it can be clearly seen from the figure that the present invention mainly consists of an insulating body 1, a plurality of conductive terminals 2, and a shielding housing 3. The insulative housing 1 has an open slot 11 at one end for corresponding insertion of other connectors, and the two sidewalls of the slot 11 have terminal slots for receiving the plurality of conductive terminals 2 12, the terminal slot 12 communicates with the slot 11, the inner side of the slot 11 is provided with a recess 14 lower than the inner surface of the slot 11 from the edge 13. The recess 14 of the embodiment is along the circumference of the slot 11. The edge 13 is a full annular recess. The plurality of conductive terminals 2 are formed by metal stamping, and each of the conductive terminals has a vertical sheet shape and is juxtaposed into two rows. The size specifications of the plurality of conductive terminals 2 and the standard USB Type-C socket electrical connector are used in this embodiment. The dimensions of the terminals are the same. The shielding case 3 is a hollow annular structure made of metal material, and can be wrapped around the circumferential side of the insulating body. The shielding housing 3 is provided with a locking portion at the leading end of the annular end. 31.
