Problems solved by technology
If the wire nose is not uniform after enamel tinning, there will be a phenomenon of easy heating; the connection between the capacitance compensation contactor and the air switch and the thermal relay has the disadvantages of excessive materials and high cost; the capacitance compensation contactor and the air switch and the thermal relay The long distance between them takes up a lot of space and the overall appearance is not beautiful; due to the non-uniform compensation capacity, the diameter of the wire used is uncertain, so mass production cannot be carried out

The invention discloses a vertical connecting structure of a capacitance compensation contactor. The vertical connecting structure mainly comprises a mounting plate, an air switch, a contactor and a thermal relay, wherein the air switch, the contactor and the thermal relay are arranged on the mounting plate; the contactor is connected with the thermal relay through an adapting piece I with a reverse Z-shaped structure and is connected with the air switch through an adapting piece II with a reverse Z-shaped structure; the air switch, the contactor and the thermal relay are arranged on the same mounting plate; the adapting piece I and the adapting piece II are designed according to the electrical performance among all the devices; the air switch is connected with the contactor through the adapting piece II instead of a lead; the contactor is connected with the thermal relay through the adapting piece I instead of a lead. Therefore, the mounting space among the devices is saved, the length of a conductive metal sheet is reduced, the favorable contact among conductors is ensured, the condition that original parts are heated is reduced, the fault rate is reduced, the service life of each device is prolonged, and the whole structure has the characteristics of reasonable design, economy, practicability, convenience in installation and the like.
Description
Technical field [0001] The present invention relates to the field of electrical appliance connection, in particular, the upper and lower connection structure of a capacitance compensation contactor. Background technique [0002] The existing connection method of the upper and lower connection structure of the capacitance compensation contactor is to match the corresponding wire diameter wire according to the compensation capacity. The two ends of the wire are crimped with the corresponding copper wire nose and tinned, and then connected to the upper air switch and the lower thermal relay. The unevenness of the wire nose after tin enamelling will cause easy heating; the capacitive compensation contactor and the air switch and thermal relay are connected by wires, which have the disadvantages of excessive material and high cost; the capacitance compensation contactor and air switch and thermal relay The long distance between them occupies a large space and the overall is not beauti...
