In addition, the terms "first", "second", "third" are only for the purpose of description, and can not be understood as indicative or implied relative importance.
[0015] In the description of the utility model, it is necessary to explain that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixed connection, can be detachable connection, or integrally connected, can be mechanical connection, can be electrical connection, can be directly connected, can be indirectly connected through the intermediate medium, can be the communication of two elements inside. For the ordinary skill in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0016] As Figs. 1-3As shown, the quick plug connector with the clamping spring protection baffle, the clamping spring is installed on the quick plug connector, one end of the quick plug connector is provided with a plug interface 1, both sides of the plug interface 1 are respectively provided with clamping grooves 3, the clamping grooves 3 are communicated with the inside of the quick plug connector through the communication ports 2 respectively, the clamping spring comprises a top 4 and two clamping arm portions 5 respectively located at both ends of the top 4 and fixedly connected with the top 4, the ends of the clamping arm portions 5 are respectively provided with bending portions 6, the clamping arm portions 5 correspond to the clamping grooves 3 one by one, the clamping arm portions 5 are clamped into the corresponding clamping grooves 3, the middle portions of the clamping arm portions 5 extend into the inside of the quick plug connector through the corresponding communication ports 2, one side of the quick plug connector is fixedly connected with two protection baffles 7, the protection baffles 7 and the quick plug connector form accommodating grooves 8 for accommodating the bending portions 6, one end of the clamping arm portion 5 is bent upwards to form the bending portion 6, the other end of the clamping arm portion 5 is bent downwards to form the bending portion 6, the two protection baffles 7 on the quick plug connector are staggered in height. The plug connector inserted into the quick plug connector is clamped by the clamping arm portions 5, so that the plug connector cannot be separated from the plug interface 1. The clamping arm portions 5 are located in the clamping grooves 3 and are not easy to be touched by external force. The bending portions 6 are arranged one above the other, which prevents the clamping spring from being directly pulled away from the quick plug connector when the clamping spring is pulled from the top 4. The protection baffles 7 protect the bending portions 6, prevent external force from acting on the bending portions 6 during use, and prevent the clamping spring from falling off.
[0017] Further, the top 4 of the clamping spring is arched outward to form an arch portion 8. The arch portion 8 facilitates the use of tools to clamp the clamping spring for installation or disassembly operation.
