Description

Technical Field

[0001] The present invention relates to the field of mechanical electronics, and more particularly to a connector and a device comprising the connector. Background Art

[0002] A connector is a device used to connect two active devices to transmit current or signals. Connectors can simplify the assembly process of electronic products and also simplify the mass production process of electronic products. Connectors are easy to repair. If an electronic component fails, the failed component can be quickly replaced with a connector. With technological advances, electronic products equipped with connectors can update electronic components and replace old electronic components with new and better-performing electronic components for easy upgrading. Connectors can improve the flexibility of product design when designing and integrating new products and when electronic components are used to form a system. Therefore, connectors are widely used in transportation, medical, aerospace, military, home appliances and other fields.

[0003] The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance.

[0004] Insertion and extraction force and mechanical life are important mechanical properties. The insertion and extraction force and mechanical life of the connector are related to the contact structure (positive pressure), the quality of the contact coating (sliding friction coefficient) and the contact arrangement size accuracy (alignment).

[0005] The main electrical properties of connectors include contact resistance, insulation resistance and dielectric strength. Among them, high-quality electrical connectors should have low and stable contact resistance, which ranges from a few milliohms to tens of milliohms; insulation resistance is an indicator of the insulation performance between the contacts of the electrical connector and between the contacts and the shell, and the order of magnitude of insulation resistance ranges from hundreds of megohms to thousands of megohms; dielectric strength is the ability to withstand the rated test voltage between the contacts of the connector or between the contacts and the shell.

[0006] Environmental performance includes temperature resistance, moisture resistance, salt spray resistance, vibration and impact resistance, etc.

[0007] The development of connector technology presents the following characteristics: high-speed and digital signal transmission, integration of various signal transmissions, miniaturization of product size, low-cost products, modular combination, convenient plugging and unplugging, etc.

[0008] Usually, the power terminals of connectors that provide high currents are generally large in size and have large spacings between each other, while the spacings between the electrodes of the chip pins or chip mainboard layouts are very small, resulting in a structural incompatibility between the power terminals that provide high currents and the chip pins or chip mainboard layouts, which ultimately results in the connector including the power terminals that provide high currents being unable to directly power the chip, which necessitates the addition of additional devices or structures to enable the connector to indirectly power the chip, which not only makes the structure of the connector that provides high currents more complicated and increases the manufacturing cost of the connector, but also increases the power consumption of the connector and reduces the working efficiency of the connector.

[0009] Therefore, it is necessary to provide a connector with a simple structure and capable of directly supplying power to the chip. Summary of the invention

[0043] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0044] The present invention discloses a connector 1000 and a device (not shown in the figure) including the connector 1000. The connector 1000 includes: a housing 100, terminals and a PCB 400 (printed circuit board).

[0045] The housing 100 is provided with a plurality of cavities 110 separated from each other, and a terminal is provided in each cavity 110. The PCB 400 includes a first electrode 410 and a second electrode 420, wherein the first electrode 410 is provided on a first surface 401 of the PCB 400 to be electrically connected to the terminal, and the second electrode 420 is provided on a second surface 402 of the PCB 400 opposite to the first surface 401 and is electrically connected to the first electrode 410 through a wire (not shown in the figure) provided in the PCB 400. At least one of the size, shape, number, and distribution of the second electrode 420 is provided to be different from that of the first electrode 410.

The terminal and the electrode of the chip pin or chip main board are usually different in shape and layout. The PCB 400 provided with the first electrode 410 and the second electrode 420 solves the problem that the terminal can only supply power to the electrode of the chip pin or chip main board by adding additional complex devices or structures due to this difference, so that the connector 1000 including the terminal for providing a large current can directly supply power to the chip pin or chip main board, which not only simplifies the structure of the connector 1000 and reduces the manufacturing cost of the connector 1000, but also reduces the power consumption of the connector 1000 and improves the working efficiency of the connector 1000.
