Description
Technical field
The utility model relates to a kind of circuit breaker element, relates in particular to a kind of draw bar of breaker of plastic casing.
Background technology
The device that the protection electric equipment is not damaged during situations such as common circuit breaker generally is used for directly, overload, short circuit or under-voltage protection appear in the alternating current circuit; When situations such as appearance overload short circuit, circuit breaker is separated iron core and static iron core by a series of actions of operating mechanism and trip gear, thus turn-off current.The draw bar of trip gear wherein has important function in action, simultaneously, draw bar is subjected to bigger pressure and bending force in the process of installing; And the draw bar intensity and the toughness deficiency of existing circuit breaker, at this problem, then generally adopt thermosets such as bakelite or DMC to make for intensity is reliable indeformable in early days, not wear-resisting, the counter-bending ability of this material, can not recycling, having for strength demand then draws the body of rod to increase metal bar or nylon rod in the centre again, so volume will increase; But along with electrical equipment industry constantly develops, existing circuit breaker all adopts miniaturization, modularization, energy-conservationization development, Gu and transfer the raw material that use thermoplastic such as Reinforced Nylon to do draw bar to, the draw bar bending resistance that this material is made good, shock-resistant good, resistance to wear is strong, material is recyclable simultaneously utilizes again, also but reduced volume adapts to miniaturization, the supporting use of modular short-circuiting device.But along with the continuous discovery in application process, this type of one-time formed structure because therefore the draw bar surface irregularity is subjected to gravitation to influence easy deformation when cooling, just can be used after needing to proofread and correct, and operation is more loaded down with trivial details; Simultaneously along with finding still after the use of a period of time that being subjected to the extraneous temperature difference and humidity to change the rear haulage bar still can be out of shape, and finally causes parts defective, and then makes whole circuit breaker product design index defective.
The utility model content
At above defective, the utility model provides a kind of draw bar of breaker of plastic casing, set up reinforcement by the stressed place of concave surface on traction peak body, thereby reach the purpose that improves whole draw bar intensity, both can prevent simultaneously whole draw bar when moulding is cooled off, influenced by gravitation and use in be subjected to the variable effect of temperature and humidity and be out of shape the situation of fracture, also save the correcting process after the moulding, enhance productivity greatly.
For achieving the above object, the utility model is by the following technical solutions:
A kind of draw bar of breaker of plastic casing, comprise the traction peak, traction lower end, peak is provided with iron core, be provided with contact-making surface between described traction peak and the circuit breaker element, be positioned at contact-making surface and be provided with the concave surface of inner concavity by bit position, this concave surface is by there being horizontally disposed reinforcement on the bit position, outwards protrude on the cylindrical structure of this reinforcement and its surface.Described traction peak is made up of the Reinforced Nylon material, and described traction peak can be provided with one or more, joins by round connecting axle between per two traction peaks and a row is formed side by side at each traction peak; The reinforcement at each traction peak and the connecting axle of both sides are positioned on the same horizontal line, and described reinforcement and connecting axle joining place are provided with a step.
The beneficial effect of the draw bar of breaker of plastic casing described in the utility model is: carry out mold pressing and form by drawing peak and iron core, and on traction peak body and the place of stepping down on other element contact-making surface of circuit breaker reinforcement is set, thereby reach the intensity that improves whole draw bar and prevent that draw bar is out of shape the purpose of fracture in installing and using, also save the correcting process after the moulding, enhance productivity greatly; In addition, be provided with a step at reinforcement and connecting axle place, in conjunction with allowing the reinforcement of bit position, thereby the gravitation when making draw bar moulding cooling reduces to minimum, has guaranteed that the deformation of draw bar reaches minimum.
