Abstract
The utility model discloses an improvement structure of plum blossom contact for circuit breaker, used spring on the contact, the spring both ends are detained mutually with the spring coil and are connected, and the spring forms the circularity. The utility model discloses not only eliminated contact pressure inequality in the plum blossom contact, double hook position contact pressure undersize causes the defect of equipment accident, makes the hookup mode of spring more reliable, insurance simultaneously, has perfected the reliability of electrical equipment operation, has improved product quality.
Description
Technical field
The utility model relates to technical field of electric appliances, a kind of specifically circuit breaker contact.
Background technology
Used 12kV Mume flower contact structure is unreliable in China's electric utility at present, and used spring is that double hook connects on the contact.The contact that connects the position at double hook does not have pressure or pressure less than other contact, the long-term use, and this position can generate heat, even can cause entire equipment to burn.Need the connected mode of contact is improved, to eliminate above-mentioned defective for this reason.
The utility model content
The purpose of this utility model is for providing the improvement structure of a kind of circuit breaker that addresses the aforementioned drawbacks with Mume flower contact.
The technical scheme that realizes the foregoing invention purpose is as follows:
Circuit breaker comprises used spring on the contact with the improvement structure of Mume flower contact, and described both ends of the spring is with the spring coil connection that interlocks, and spring forms annular.
Described both ends of the spring with spring coil interlock be connected to both ends of the spring screw at least 3 the circle.
Described both ends of the spring is provided with a hairspring in the place of being interlockingly connected.
The described both ends of the spring place of being interlockingly connected is provided with a snap ring, described spring and hairspring is buckled together.Described snap ring twist, inward at both ends bending, the inflexed two ends of snap ring snap in the hairspring.
The spring bind mode that adopts in the utility model, not only perfect contact pressure inequality in the Mume flower contact, double hook position contact pressure is too small, cause equipment breakdown, make the connecting mode of spring more reliable simultaneously, insurance, the perfect reliability of electric equipment operation has improved product quality.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Figure 1-3, circuit breaker comprises used spring 1 on the contact with the improvement structure of Mume flower contact, and described spring 1 two ends are with spring coil connections that interlock, and both ends of the spring screws in 4 and encloses, and spring forms annular.Be provided with a hairspring 3 in the described both ends of the spring place of being interlockingly connected 2, it is more firm that spring 1 is connected.Be provided with a snap ring 4 at the described both ends of the spring place of being interlockingly connected 2, described spring 1 and hairspring 3 be buckled together, described snap ring 4 twist, the inward at both ends bending, the inflexed two ends of snap ring snap in the hairspring.The design of snap ring has increased the spring connection stability, makes the junction be difficult for throwing off, and makes the connected mode of spring more reliable.
