Description

Clamshell Connector

technical field

The utility model relates to a flip-top connector, in particular to an RJ45 type connector which can be applied to Internet cables. The mating docking connector plugs in and automatically collapses when not in use.

Background technique

With the advancement of science and technology, various communication devices are constantly being innovated under the demand of easy-to-use, powerful functions, light-weight and easy-to-carry. However, these products require cables to transmit and receive electronic signals, so they are usually used Standard-sized mating plugs are connected to network cables to realize signal transmission and reception.

Existing electrical connectors of this type generally include an inserting surface that can match the size of the mating plug, an integrally formed insulating body, and terminals accommodated in the insulating body. However, due to the limitation that the insulation body retains a preset height for matching the mating plug, especially when the electrical connector is mounted on a computer memory card (PCMCIA), the volume of the entire computer memory card (PCMCIA) will be very large. Due to the large size, it causes a lot of inconvenience for users to store and carry; and due to the volume of the insulating body, the installation point of the electrical connector in the portable device is greatly restricted. It is easy to make dust adhere to the terminals and cause poor contact.

In order to solve the above problems, the industry has designed a clamshell electrical connector, which includes an insulating body and terminals accommodated in the insulating body. The insulating body is two-piece, which includes a base body and a cover plate pivotally connected to the base body. When the cover plate is opened, it can form an insertion surface with the base body to accommodate the docking plug, and when the docking plug is pulled out, it can be retracted. Combined, since the insulating body adopts two pieces, the overall height can be reduced and the product can be made lighter and thinner.

As shown in FIG. 9 , US Patent No. 6,905,351 discloses a clamshell electrical connector. The clamshell electrical connector includes a base body A1, on which a terminal assembly A2 is arranged, and a cover plate A3 is arranged above the base body A1. connected so that the cover A3 can be opened or closed relative to the base A1 in a translational manner, and an accommodation space (not shown in the figure) is formed between the base A1 and the cover A3 to accommodate a phase Mating mating connector A20. No matter the cover A3 is closed, opened or moved, it remains parallel to the base A1.

Wherein the linkage element on the rear side of the electrical connector is a connecting rod A51, and the linkage element on the front side of the electrical connector is an elastic element A41. When the cover A3 is opened, the elastic element A41 will accumulate a Restoration force, when the matching butt connector A20 is pulled out from the accommodation space (not marked in the figure) formed between the cover A3 and the base A1, the cover A3 can pass through the elastic element A41 The recovery force is automatically closed on the base A1. Since the electrical connector is positioned by the two sticking points of the connecting rod A51 and the elastic element A41, the cover plate A3 stays in the open or closed upper and lower positions, and the sticking points are easily worn due to frequent use and cannot be locked. The cover plate A3 may be in a closed and fixed state and lose its function, so it is necessary to improve this.
