This application claims the benefit of Chinese Patent Application No. 202222719091.7 filed on Oct. 14, 2022 in the China National Intellectual Property Administration, the whole disclosure of which is incorporated herein by reference.
Embodiments of the disclosure generally relate to a connector.
A connector is a device used to connect two elements to transmit current or signals therebetween. A connector may simplify an assembly process of electronic products, and thus their mass production. The utilization of connectors increase the ease of component repair or replacement, as faulty electronic component may be quickly replaced with a connector installed. With the advancement of technology, electronic products equipped with connectors may update electronic components, replacing old electronic components with new and better performing ones for easy upgrading. A connector may enhance the flexibility of product design when designing and integrating new products, as well as when composing a system with electronic components. Therefore, connectors are widely used in fields such as transportation, healthcare, aerospace, military, and home appliances.
The basic performance of a connector may be divided into three categories: mechanical performance, electrical performance, and environmental performance. Plugging force and mechanical life are important mechanical performances. The plugging force and mechanical life of a connector are related to a structure (positive pressure) of an element contacting with the connector, a coating quality of a contact area (sliding friction coefficient), and a size accuracy of a contact arrangement (alignment). Main electrical performances of a connector comprise a contact resistance, an insulation resistance, and a dielectric strength. Among them, a high-quality electrical connector should have a low and stable contact resistance, which ranges from a few milliohms to tens of milliohms. An insulation resistance is an index that indicates an insulation performance between contacts of an electrical connector and between the contacts and a housing of the electrical connector. An order of magnitude of the insulation resistance ranges from hundreds of megaohms to thousands of megaohms. Dielectric strength is an ability of the electrical connector to withstand a rated test voltage between the contacts of the electrical connector or between the contacts and the housing of the electrical connector. Environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration and impact resistance, etc.
In recent years, in applications of large-scale integrated devices and equipment, it is necessary to transmit multiple different signals at a high power between various components simultaneously. Accordingly, a connector must be equipped with more terminals to meet a growing performance needs for devices and equipment. This poses new challenges for a design of the connector.
According to an embodiment of the present disclosure, a connector includes a housing in which is provided at least one first terminal adapted to transmit a first current, at least one second terminal adapted to transmit a second current, and at least one third terminal adapted to transmit a signal. A total number of the at least one first terminal, the at least one second terminal, and the at least one third terminal is twenty-six.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
