The invention provides a connection assembly between the connection terminals of an electric switchgear. The connection assembly comprises a housing, a coil former, a left / right coil incoming / outgoing wire terminal, a left / right coil control wiring terminal, and a tension spring. The tension spring connects the coil incoming / outgoing wire terminal with the coil control wiring terminal. The connection assembly is characterized in that the coil incoming / outgoing wire terminal is connected with the coil control wiring terminal by the tension spring, so that the current is led to the coil incoming / outgoing wire terminal from the coil control wiring terminal. In this way, the actuating and releasing function of a contactor is realized. The tension spring not only realizes the effect of physical contact, but also realizes the effect of electrical connection at the same time. Therefore, the connection assembly is practical. Moreover, the reliable connection of the coil incoming / outgoing wire terminal with the coil control wiring terminal is realized by the tension spring, so that the size of the product is reduced. The production efficiency is improved. In addition, the wiring operation of users is facilitated, and the material utilization rate is improved.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliance control, in particular to a connection assembly used between terminals of an electric switchgear; it is mainly used for connecting coil inlet and outlet terminals and coil control terminals of a contactor. Background technique [0002] At present, the design of the input and output terminals of the contactor coil is relatively complicated, which is manifested in many matching features, high demand for limit accuracy and matching accuracy, complicated manufacturing process, and low material utilization rate, which are not conducive to the company's mass production, cost control and quality. Implementation of control. To solve the above problems, the elastic connection method is invented, which simplifies the design difficulty and manufacturing process of the coil inlet and outlet terminals. Contents of the invention [0003] The present invention is to provide a connection assembl...
