Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a connector with a side pressure unlocking structure. Background Art

[0002] At present, angled connectors are widely used in various energy storage products such as industrial and commercial energy storage, household energy storage and mobile energy storage. Due to the limitations of product structure and actual practical environment, if the unlocking structure of the angled connector is inconvenient, it will waste time and be inefficient when plugging and unplugging. In serious cases, it may even cause problems such as improper installation or violent disassembly causing damage to the interface. Therefore, manufacturers and users of various angled connectors are eager to obtain an angled connector with an unlocking structure that is easy to operate and reliable to install.

[0003] There are two main types of unlocking structures for angled outlet connectors currently on the market: One is to press on the top of the angled connector, which is not convenient to operate when the installation space is relatively narrow. In practical use, it is necessary to pinch the left and right sides and press the top button at the same time, which is very difficult to operate. When used in connectors with large plug-in and pull-out forces, the plug cannot be unplugged with one hand, which is inconvenient to operate. One method is to press the side of the angle connector, but the button is generally only on one side and is only suitable for one-handed operation. When the connector can only be pulled out by pressing the button with the other hand due to some installation environment reasons, the operation will be very inconvenient. After multiple operations, the user will feel very tired and unable to operate for a long time, resulting in low efficiency. Summary of the invention

The unlocking structure of the present invention can be operated with one hand. When the lock is pressed, pinch the plug 1 and pull it out. It is convenient to unlock with either hand. The unlocking structure conforms to ergonomic operation. The inclined surface of the inclined clamping head 1062 corresponds to the guiding slope of the inner wall of the insertion port 202, so that the inclined clamping head 1062 can be automatically guided to lift up when the plug 1 and the socket 2 are plugged in. After the plug-in is completed, the connecting piece 1061 is reset by the push of the rotary spring 107, so that the inclined clamping head 1062 is automatically snapped into the snap-in groove 203, so as to realize the snap-in fixation and achieve the purpose of easy locking.
