Description

A terminal group of an electrical connector

technical field

The utility model relates to a terminal set of an electrical connector, in particular to a terminal set conforming to the specification of universal connection port 3.0. The insulation layer of the wire is installed, so that the metal core inside the insulation layer contacts the cutting edge of each terminal, and forms clamping, positioning and electrical conduction, thereby achieving the effect of quickly positioning the metal core.

Background technique

With the evolution of the times, technology is also advancing at a rapid pace. In this era of technology and knowledge explosion, various electronic devices are widely used in daily life, from PDA (PERSONAL DATA ASSISTANT) that records important personal data Personal computers that perform various operations have gradually become an indispensable part of people's lives. People use various electronic devices to perform operation processing or information storage to assist in the work. The transmission methods between various electronic devices In order to plug in the connectors with transmission lines, each electronic device can transmit information such as pictures, files, programs and other data to each other. In the technological era where every second counts, the transmission rate of each electronic device will change during the transmission process. It is quite important, and the serial transmission connectors commonly used today include the forms of Universal Serial Bus (Universal Serial Bus-USB) 1.1 and 2.0, and their general transmission rates are 12Mbit/s and 480Mbit/s respectively Transmission rate, however, due to the increasing amount of data to be transmitted by electronic devices, the capacity is also increasing. In this case, the transmission speed of the original transmission joint will not be enough. A high-speed transmission connector, such as Universal Serial Bus 3.0, whose transmission rate can be as high as 5Gbit/s, and in order to make the traditional Universal Serial Bus 1.1 or 2.0 still connected to it, to achieve downward compatibility, so The method of retaining the original terminal group and adding another terminal group forms the current type of Universal Serial Bus 3.0. In summary, Universal Serial Bus 3.0 has two different terminal groups, and this A universal serial bus 3.0 electrical connector can use the butt end on one side of the terminal group to engage with the external connector, and use the contact end on the other side of the terminal group to be soldered to the circuit board or the preset wire. However, if When it is desired to be electrically connected to the preset wire, the preset wire and the terminal need to first cut off the insulating layer covered on the surface of the preset wire, so that the metal core inside the insulating layer is exposed, and then the metal core is removed. The contact end of the terminal group is soldered using Surface Mount Technology (SMT). The surface mount technology needs to be accurately aligned at the welding position between the contact end and the metal wire core through solder paste or solder balls, and then use a reflow furnace Wait for the high-temperature equipment to weld the contact end and the metal wire core, and wait for the welding place to cool before proceeding to the next procedure. This method of connecting the metal wire core to the contact end of the terminal group has the following disadvantages:

(1) When the terminal group of the existing electrical connector is assembled with the preset wire, it is carried out by welding, and the insulating layer outside the metal wire core must be removed first, so that the metal wire core is exposed to the outside, and then tinned After the paste or solder balls are accurately aligned at the soldering point, use high-temperature equipment to solder the contact end and the metal wire core, and then wait for the solder at the soldering point to cool before proceeding to the next step of assembly, but this method will consume more time costs and processing costs.

(2) The existing electrical connectors meet the requirements of lightness, thinness, shortness, smallness and good function, so the volume occupied by them should be reduced as much as possible in production, and another terminal group should be added in the form of traditional universal serial bus , so that the terminal groups of the existing electrical connectors form a dense arrangement and improve their space utilization and functionality. However, during the soldering process between the terminals and the wires, the solder that is heated and welded may flow to make the contact terminals easy to interact with each other. Conduction causes a short circuit, or forms an empty solder joint during welding of the metal core, thereby affecting the transmission of the Universal Serial Bus, thereby significantly reducing the reliability and yield of the Universal Serial Bus.

Therefore, how to solve the above-mentioned existing problems is the direction that relevant manufacturers engaged in this industry want to research and improve urgently.
