Description

Two-way electrical connector

The present invention relates to an electrical connector, in particular to a bidirectional electrical connector.

The most popular signal transmission specification for computer equipment today is Universal Serial Bus (USB for short). Connector sockets and transmission lines made of this specification can be used to connect external peripheral equipment to the computer, such as mouse, keyboard, portable Discs, etc., are measured by the computer and used immediately.

At present, both the USB socket and the USB connector are connected electrically in one direction. In order to ensure that the USB connector can be electrically connected when it is inserted into the USB socket, the two have a fool-proof design on the docking, that is, when the USB connector is inserted in the opposite direction, it cannot be inserted. Use Or it will be inserted in another direction, and it can be inserted only when the direction is correct, so as to ensure that there is an electrical connection after insertion.

At present, there are two specifications of USB 2.0 and 3.0, please refer to Fig. 1 and Fig. 2, which is the existing USB 2.0 specification and has a plate type connector disc 1, which is provided with a plastic base 10 and a circuit board 15 The rear section of the circuit board 15 is covered by the plastic seat body 10 , and only one board surface of the front section of the circuit board 15 is exposed outside the plastic seat body 10 , and the board surface is provided with a row of four contacts 16 .

Please refer to Fig. 3, it is the electrical connection base 20 of the existing USB2.0 specification, which is provided with a metal shell 25 and a tongue 22, a connection groove 21 is formed in the metal shell 25, the tongue 22 is located at the upper position of the connection groove, and only the bottom of the tongue is provided with a row of 4 contacts 23, the top surface of the metal shell 25 And each stamping of bottom surface protrudes two shrapnels 24.

Please refer to Fig. 4, in use, the flash drive 1 must be inserted into the connection groove 21 with the contacts 16 facing upwards to be electrically connected to a row of contacts 23 located under the tongue 22, and the four elastic sheets 24 are pressed against the Disc body 1; if the disc body 1 is inserted into the connection slot 21 on the reverse side, it will not be electrically connected. The user usually inserts it randomly, so the probability of not being able to insert it is 1/2, so it is often inserted twice, resulting in trouble in use. inconvenient.

For the convenience of use, it is still necessary to be electrically connected in both directions to meet the requirements. Therefore, the applicant has developed an electronic device with a double-sided electrical connection function and a front-to-back double-sided connector. , then the connector must be designed with two rows of contacts. However, in use, it is feared that the shrapnel 24 electrically connected to the female seat will abut against the contacts on the other board and cause a short circuit, so this problem must also be overcome.

The applicant of the present invention devoted himself to researching the double-sided plug-in design of the above-mentioned products, and finally proposed an improved product structure to overcome the above-mentioned potential problems.

The main purpose of the present invention is to provide a two-way electrical connector, wherein both the upper and lower boards of the docking structure have contact points, so as to achieve convenience and versatility in use.

In order to achieve the above purpose, the present invention provides a bidirectional electrical connector, which is a bidirectional butt joint electrical connector, which includes: a butt joint structure, the butt joint structure is provided with an insulator, the front end of the insulator is provided with a connecting part, the The connecting part is a connecting plate, and the connecting plate is provided with upper and lower board surfaces, each of which is provided with a connection interface, each of the two connection interfaces is provided with at least one row of contacts, and each of the at least two rows of contacts is provided with A plurality of contacts of different circuits, the at least two rows of contacts are arranged on the connecting plate On the upper and lower board surfaces, the at least two rows of contacts are formed on at least one row of terminals, and the at least one row of terminals is positioned on the insulator of the butt joint structure. One of the connection slots of the docking electrical connector; the characteristic is that the rear section of the connection plate is thicker than the front section.

With the above structure, the present invention can achieve convenience and diversity in use.

The above and other objects, advantages and features of the present invention can be more clearly understood from the detailed description of the preferred embodiments with reference to the drawings.
