Description

M283360 IV. Creation Instructions (1) [Technical Field of New Type] This creation is to provide an electrical connector, especially an electrical connector that can effectively prevent short-circuiting of terminals. [Previous technology] In the current electronics field, electronic devices are increasingly miniaturized. In order to adapt to this trend, electrical connectors are also trending towards lighter, thinner, shorter and smaller. Therefore, the distance between terminals is designed to be smaller and smaller. This requires higher and higher requirements for preventing terminal short circuits. Please refer to the electrical connector disclosed in U.S. Patent No. 60 No. 3, the upper and lower rows of which are electrically conductive ^ are staggered from each other. In order to prevent the terminal from short-circuiting, a plurality of spacers are provided on the rear wall of the insulating body to connect each conductive terminal. Separated. However, as the demand for high-speed and Otani signal transmission is further met, the number of conductive terminals of electrical connectors will increase sharply. 'Continue to use the upper and lower rows of conductive terminals staggered with each other will occupy absolutely = the body is too long, Therefore, it is possible to set the upper and lower rows of conductive terminals to the corresponding arrangement of the rear row-a practical method, see the electrical connector disclosed in U.S. Patent Bulletin No. 6'375,506. Its guide is set to W The rear and second rows are arranged correspondingly, and the slot walls between the conductive terminals in the same row are separated. 'It is disclosed in the patent that there is no isolation structure between the front and rear rows. When it is at the end of the channel, it is very easy to push it with excessive force; the connection part of the row of the body of the body hits a #, causing the terminal to be short V! 钿: The crime is passed near the tail, and the product loses its work, which affects the normal terminal. Best of all, it is indeed necessary to improve the aforementioned electrical connector to overcome the previous
