Technical Field

The present utility model relates to a connector structure, and more particularly to an improved serial bus connector structure.

Background

With the development of technology, a variety of electronic devices, such as mobile phones, tablet computers or digital cameras, are widely used, and various electronic devices can be connected to each other through various connectors to perform data transmission, wherein universal serial bus connectors (Universal Serial Bus, USB) are widely used in various connectors.

In order to meet the requirements of new-generation handheld electronic devices, a completely new design of USB Type-C connector is developed in the prior art, and a major feature of the USB Type-C connector is to allow a user to plug in with another mating connector in a front or back direction. In order to achieve the above characteristics, the USB Type-C connector must include at least 24 terminals, and the at least 24 terminals are divided into an upper row of terminals and a lower row of terminals, and the upper row of terminals and the lower row of terminals are symmetrically arranged with each other so as to meet the requirement of allowing bidirectional plugging. In addition, the USB Type-C connector further includes a conventional base plate assembly disposed between the upper and lower rows of terminals to reduce signal interference between the upper and lower rows of terminals.

For example, taiwan patent publication No. TWM521814U (hereinafter referred to as the foregoing disclosure) discloses an electrical connector, which comprises a base board assembly, a first terminal block, a second terminal block, a first row of terminals, a second row of terminals, an insulating body, at least one conductive cover plate and an external shielding body. The first terminal seat and the second terminal seat respectively cover a part of the first row of terminals and the second row of terminals and are combined with the insulating body; the base plate assembly is arranged between the first terminal seat and the second terminal seat and is used for avoiding static electricity, discharge or electromagnetic wave interference between the first row of terminals and the second row of terminals; the insulating body is provided with a plurality of terminal channels, and each terminal channel is used for accommodating the other parts of the first row of terminals and the second row of terminals; the at least one conductive cover plate is arranged on the outer surface of the side wall of the insulating body; the outer shielding body is used for being sleeved on the insulating body and the at least one conductive cover plate.

However, the structural design of the base board assembly in the prior art still cannot effectively completely separate the upper row terminals and the lower row terminals, so that the USB Type-C connector cannot meet the standard of high frequency characteristics such as IMR (INTEGRATED MULTI-Reflection) or IRL (Integrated Return Loss) when performing high frequency test, and for example, the base board assembly is disposed between the first terminal base and the second terminal base in the prior art, but the requirement of high frequency characteristics cannot be met when performing high frequency test.

Therefore, it is necessary to provide a solution to the problem of the high frequency characteristics.

Disclosure of utility model

In view of the above-mentioned shortcomings of the prior art, it is a primary object of the present utility model to provide an improved structure of a serial bus connector, which can improve the performance of the existing serial bus connector in terms of high frequency characteristics by only improving the basic components.

In order to achieve the above object, the present utility model adopts the main technical means that the improved structure of the serial bus connector comprises:

A midplane comprising a base and a tongue extending from the base;

An upper row of terminals provided at an upper end of the base, the upper row of terminals having a first contact portion extending toward the tongue portion;

A lower row of terminals provided at a lower end of the base, the lower row of terminals having a second contact portion extending toward the tongue portion;

The first width of the first contact portion of the upper row of terminals, the second width of the second contact portion of the lower row of terminals and the third width of the tongue portion are identical in width.

According to the connector, when the middle partition is positioned between the upper row of terminals and the lower row of terminals, the first width of the first contact part of the upper row of terminals, the second width of the second contact part of the lower row of terminals and the third width of the tongue part are identical in width, and the connector is in a structure state of being uniform and wide, and the connector can achieve the aim of improving the high-frequency characteristic performance by improving the structure.
