Description

The present invention relates to electrical connectors, especially bidirectional double-sided electrical connectors.

With the increasing functionality of various electronic products and the widespread use of handheld devices, the demand for signal transmission between various products or devices is also increasing. Of these, signal transmission between devices is performed via a signal interface. The signal interface is, for example, an electrical connector or a complementary electrical connector that mates with it. The electrical connector is an electrical receptacle and the complementary electrical connector is an electrical plug.

Before fitting the electrical connection plug into the electrical connection socket, the electrical connection plug must be oriented in the correct direction towards the electrical connection socket, so that the two can be mated. That is, the electrical connection socket has a plug-in directionality, which is a so-called foolproof malfunction prevention function, which ensures that the connection interface of the electrical connection plug is reliably in contact with the contact terminal on the electrical connection socket. However, most users do not have the habit of connecting the electrical plug to the electrical connector in the correct direction. Due to this malfunction prevention function, the fitting of the electric connection plug and the electric connection socket fails, and then the electric connection plug is turned over again to fit correctly. In other words, this foolproof malfunction prevention feature is confusing to the user.

Therefore, the market provides bidirectional electric connectors having a double-sided fitting function, and two sets of contact terminals are provided in order to eliminate the plug directivity of the bidirectional electric connector. The user can fit in either direction between the bidirectional electrical connector and the complementary electrical connector. However, the conventional bidirectional electric connector has a high manufacturing cost and its functional reliability is low. Therefore, how to make bidirectional electrical connectors stable and reliable and reduce the cost of electrical connectors is a common goal of the industry.

A main object of the present invention is to provide a bidirectional double-sided electric connector which can reduce manufacturing cost and assembly cost and has a bidirectional fitting function of the bidirectional electric connector.

In order to achieve the above object, the bidirectional double-sided electric connection provided by the present invention includes two insulating pedestals, two rows of terminals, and a metal outer shell.

The insulating pedestal is integrally provided with a base portion and a fitting portion, and the fitting portion is connected to the tip of the base portion. The fitting portion includes a bottom plate and two side plates, and is provided with a contact surface that is abutted against each other and comes into contact with the inner surfaces of the two insulating pedestal bases. A connecting tank is formed between the bottom plates of the fitting portions of the two insulating pedestals, and the front side portion of the bottom plate has a low flat surface and the rear side portion has a high flat surface. The two side plates of the two insulating pedestal fittings abut against each other to form a sleeve frame. On the inner surface of the two insulating pedestals, a row of partitions divided into a row of terminal tanks extending in the front-rear direction is provided. One end of each terminal tank has a bottom surface, both sides of the bottom surface are connected to the partition, and the other end of the terminal tank is an open end.

The two-row terminals are vertically assembled to the two-row terminal tanks of the two insulating pedestals. The terminal is integrally provided with an elastic portion, a fixing portion, and a pin from the front portion to the rear portion. The front portion of the elastic portion corresponds to the fitting portion and is bent so as to have a contact portion protruding vertically from a high plane. The elastic portion can elastically move up and down. The rear part of the elastic part is at the same height as the fixed part and abuts on the bottom surface of the terminal tank. Since the depth of the terminal tank is larger than the material thickness of the terminal, the rear part and the fixed part of the elastic portion are confined in the terminal tank. The insulating pedestal is provided with a fixing structure for fixing the terminal row. The rear part of the elastic part of the terminal row can still elastically move up and down with respect to the bottom surface of the terminal tank. The pins extend to the rear end of the base and are exposed, and the same contact circuit serial numbers at the contacts of the two rows of terminals are arranged to face each other.

The metal outer shell covers the two insulating pedestals and has a four-sided cover main shell. The four-sided cover main shell shields the fitting portions of the two insulating pedestals, both form a fitting structure, and the fitting structure can be positioned in the forward and reverse directions within the pair of electric connectors.

The rear portion of the elastic portion of the two-row terminal is at the same height as the fixed portion and abuts on the bottom surface of the terminal tank, so that assembly and stamping are easy and the manufacturing cost is reduced. Further, the rear part of the elastic part of the terminal is pressed horizontally against the bottom surface of the terminal tank to support the middle part of the elastic arm, and the positive force and elasticity of the terminal contact become stronger.

The above and other objects, advantages and features of the invention will become more apparent from the detailed description of the following preferred embodiments with reference to the accompanying drawings.

The present invention relates to electrical connectors, especially bidirectional double-sided electrical connectors.

With the increasing functionality of various electronic products and the widespread use of handheld devices, the demand for signal transmission between various products or devices is also increasing. Of these, signal transmission between devices is performed via a signal interface. The signal interface is, for example, an electrical connector or a complementary electrical connector that mates with it. The electrical connector is an electrical receptacle and the complementary electrical connector is an electrical plug.

Before fitting the electrical connection plug into the electrical connection socket, the electrical connection plug must be oriented in the correct direction towards the electrical connection socket, so that the two can be mated. That is, the electrical connection socket has a plug-in directionality, which is a so-called foolproof malfunction prevention function, which ensures that the connection interface of the electrical connection plug is reliably in contact with the contact terminal on the electrical connection socket. However, most users do not have the habit of connecting the electrical plug to the electrical connector in the correct direction. Due to this malfunction prevention function, the fitting of the electric connection plug and the electric connection socket fails, and then the electric connection plug is turned over again to fit correctly. In other words, this foolproof malfunction prevention feature is confusing to the user.
