I. FIELD OF THE INVENTION
The present invention relates to the technical field of automobile connector terminals, in particular to a vibration-resistant socket terminal and a vibration-resistant plug terminal.
II. BACKGROUND OF THE INVENTION
Connectors are important electronic components in automobiles and play a role in power and signal transmission. The conductive performance of the connectors affects the functionality of the electrical components in the vehicle and even affects driving safety. Each connector consists of two parts, a plug and a socket. The plugs and sockets usually comprise parts such as sheaths and terminals, wherein the terminals are generally made of metal and are important components for realizing the functions of connectors, and the functions of connectors are realized by the stable contact between the plug terminals and the socket terminals.
The bumps generated during the driving of the vehicle will cause vibration of the connector. The macroscopic vibration will change the stress state of the spring plate on the connector, and the positive pressure provided by the spring plate will change, which may cause the connector to fail instantly. The micro-movement between the terminals caused by microscopic vibration will cause the wear and tear of the terminal surface coating, accelerate the oxidation of the terminal surface, increase the contact resistance between the terminals, and thus cause the connector to fail. Vibration is a common and important factor causing connector failure, and during the driving of the vehicle, vibration and impact are inevitably generated. Automotive connectors need to withstand more severe vibration environments, so higher requirements are placed on the vibration resistance. Therefore, conducting vibration-resistant design for automotive connectors is an important technical requirement.
For example, the Chinese patent with the publication number CN210723464U discloses a suspension movable connector, comprising a socket body, guide columns, spring holes, socket terminal holes, socket movable columns, springs, socket terminals, mounting plate screws, a mounting plate, mounting plate screw holes, mounting plate cylinders, mounting plate square holes, a fixing plate, fixing plate screw holes, a fixing plate baffle, fixing plate screws, a plug body, plug terminal holes, plug guide holes, plug screw holes, plug terminals and plug fixing screws. The suspension movable connector comprises a socket body and a plug body, guide columns are fixedly and symmetrically arranged on the socket body, and a spring hole is formed in the guide column; socket terminal holes are fixedly formed in the upper end face of the socket body, socket movable columns are fixedly arranged on the socket body, socket terminals are installed in the socket terminal holes, one end of each spring is installed in the corresponding spring hole, the other end of each spring is fixed to the corresponding mounting plate cylinder, and the mounting plates are sleeved on the socket movable columns through the mounting plate square holes.
The vibration damping solution described in the above public document involves setting up springs on the socket housing body to reduce the vibrations. The springs keep the socket closely attached to the plug on the battery end, allowing the socket and the plug to move longitudinally together, thereby reducing frictional forces between the plug and socket on the battery. This indirectly reduces the vibration of the connector terminals. This application is an improvement on the connector housing body, while the stable contact between the plug and socket depends on the stable positive pressure provided by the socket terminal spring plate. The positive pressure of the socket terminal spring plate in this application has not changed, this application relies on improvements to the connector housing body to achieve stability between the plug and socket on the connector, without improving the inherent stability of the plug and socket themselves, and the socket terminal spring plate cannot provide the positive pressure enabling the plug terminal and the socket terminal to be stably plugged.
