[0002] It is known that the circuit breaker refers to the switching device that can close, carry and open the current under the normal circuit condition and can close, carry and open the current under the abnormal circuit condition within the stipulated time. The circuit breaker is divided into the high-voltage circuit breaker and the low-voltage circuit breaker according to its use range, can be used to distribute electric energy, start the asynchronous motor infrequently, carries out protection to the power supply line and motor and the like, can automatically cut off the circuit when the serious overload or short circuit and under voltage fault of them occurs, and the function is equivalent to the combination of the fuse type switch and the over-under voltage relay. Moreover, it is generally not necessary to change the parts after breaking the fault current. It has obtained the wide application.
[0003] The circuit breaker body mechanism is generally connected with other parts through the cable plug-in cable, and the current connecting mode is that the cable is directly plugged in the circuit breaker body mechanism, and the durability is generally poor, and the connection failure can occur after long time use. UTILITY MODEL CONTENTS
[0004] The utility model adopts the technical scheme that a circuit breaker cable supporting structure, it includes the plug-in protective sleeve and the supporting cover, the plug-in protective sleeve is connected with the supporting cover and forms a whole, wherein, the plug-in protective sleeve includes the plug-in arc plate, the outer arc plate and a plurality of protective ribs, a plurality of the protective ribs are fixedly connected between the plug-in arc plate and the outer arc plate, an inner cavity is formed around by the plug-in arc plate, the outer arc plate and a plurality of the protective ribs, the plug-in slot is set up on the circuit breaker body corresponding to the plug-in arc plate, the cable socket is set up on the circuit breaker body, the plug-in slot is located above the cable socket, and the plug-in arc plate is movably inserted in the plug-in slot.
[0005] The supporting cover is located below the outer arc plate of the plug-in protective sleeve, the supporting cover includes the lower arc plate and the connecting strip, the connecting strip is connected between the outer arc plate of the plug-in protective sleeve and the lower arc plate, and a supporting cavity is formed around by the outer arc plate and the lower arc plate, and the supporting cavity is communicated with the inner cavity.
[0006] The utility model discloses beneficial effect for: the utility model uses, cable plug inserts in the cable socket in proper order through the supporting cavity and the inner chamber, and then, the plug -in arc plate is inserted in the plug -in slot, at this moment, the plug -in protective sheath whole covers and sets in the cable plug and the plug -in slot top, plays the role of protection, anti -collision, the supporting sleeve is located the cable plug below, and the supporting sleeve plays the role of supporting the weight of cable plug, to make the cable plug steady connection in the plug -in slot's effect, the utility model has the characteristics of simple structure, and the protection effect is good.
