High-temperature-resistant connector for charging pile and manufacturing and assembling method of high-temperature-resistant connector

Abstract

The invention discloses a high-temperature-resistant connector for a charging pile. The high-temperature-resistant connector comprises a connector male head and a connector female seat, the connector male head comprises a male head body and a component accommodating part, and the communication component accommodating part is provided with a power line butt joint part and a terminal arrangement part; the connector female seat comprises a female seat body and a terminal accommodating part, and a male head inserting part is arranged around the terminal accommodating part; the terminal setting part is detachably inserted into the male head insertion part in a sealed manner, so that the terminal setting part is electrically connected with the terminal accommodating part; the connector male head and the connector female seat are made of high-temperature-resistant materials, so that the butt-joint power-on stability of the terminal arrangement part and the terminal accommodating part is prevented from being affected. The invention further discloses a manufacturing and assembling method of the high-temperature-resistant connector for the charging pile. According to the charging pile connector, an embedded assembly mode is adopted, the stability and safety of conductive charging can be enhanced, the problems of poor contact, interface damage and the like caused by loosening can be prevented, and then the mechanical properties of vibration resistance, impact resistance and the like of the charging pile connector are improved.

Description

technical field [0001] The invention relates to the technical field of charging connectors, in particular to a high temperature resistant connector used for charging piles and a method for manufacturing and assembling the same. Background technique [0002] With the development of science and technology, lithium batteries have become the most popular new energy batteries in new energy vehicles at this stage. That is 2.4V ~ 4.2V, it is necessary to require the charging pile to stably output the above charging voltage range, otherwise it will cause permanent damage to the lithium battery. However, after long-term charging and use, the charging pile connector may generate a lot of heat, which will affect The conductive transmission quality of the internal terminals of the connector, therefore, the most critical thing for the daily charging of the lithium battery using the charging pile is to choose a connector with good current transmission performance. The connector includes ...

Problems solved by technology

[0002] With the development of science and technology, lithium batteries have become the most popular new energy batteries in new energy vehicles at this stage. Its biggest advantage is that it can be connected to charging piles to realize charging functions, but lithium batteries have ideal lower voltage limits and upper voltage limits. It is 2.4V~4.2V. It is required that the charging pile can stably output the above charging voltage range, otherwise it will cause permanent damage to the lithium battery. However, after a long time of charging, the charging pile connector may generate a lot of heat, which will affect The conductive transmission quality of the internal terminals of the connector, therefore, the most critical thing to use the charging pile for daily charging of lithium batteries is to select a connector with good current transmission performance

The connector includes a male head and a female seat. Most of the male heads on the market currently adopt a straight head structure, that is, the extension direction of the power cord is the same as the plugging direction of the terminal. This structure requires a large space for electronic equipment and power cords to be placed. , resulting in inconvenience for users; secondly, the male and female sockets usually only contain two sets of terminals, which cannot be applied to carry the large current of the corresponding charging voltage, and the charging stability is poor; and the traditional male and female sockets adopt an exposed docking method , that is, the docking surface of the male head and the female seat is flush. This docking method will cause the charging pile connector to loosen, oxidize or have poor contact after long-term plug-in use or external force, making charging unstable and reducing charging. The service life of the head will affect the normal use
