Problems solved by technology

[0003] First, the button assembly is easy to crack under the action of tension, and the insufficient interference will cause the assembly to fall off;
[0004] Second, the button is made of polysulfone plastic, which is not resistant to organic solvents and is prone to quality problems;
[0005] Third, the production process of the original bracket is relatively complicated, and the qualified rate of parts is low;
[0006] Fourth, the assembly efficiency is relatively low

Embodiment Construction

[0018] The technical scheme of the present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0019] See attached Figure 1~5 As shown, an integral button for an aviation circuit breaker, including a bracket 2 and a button 1, is characterized in that:

[0020] (1) Bracket 2 is integrally formed by ZLD-105 aluminum alloy. Two annular grooves 3 are processed on the circumferential surface of the connecting end 4 of bracket 2 and button 1. The width of the annular groove 3 is 1 mm and the depth is 0.5 mm. , the distance between the two annular grooves 3 is 1mm. On the connecting end 4, two parallel step surfaces 5 are processed along the direction of the central axis 6 of the bracket 2. The two step surfaces 5 are symmetrical with respect to the central axis 6. The two steps The surface 5 is parallel to the strip-shaped movable piece installation groove 7 of the bracket 2, and the maximum distance between the stepped su...

Abstract

The present invention relates to an integral button for an aviation circuit breaker. The integral button is a structural form in which a separate bracket is transformed into an integral bracket and molded together with the button to improve the mechanics of the bracket and the button in the aviation circuit breaker. It provides good processability for the casting of the bracket, the plastic pressing of the button, and the assembly of the button parts, which can improve the production efficiency and product quality several times.

Description

technical field [0001] The invention relates to an integral button for an aviation circuit breaker, which belongs to the technical field of product molding and processing. Background technique [0002] The existing circuit breaker bracket is to use two single (half pieces) brackets to press into the button with an interference fit, and to coat a certain amount of adhesive. During use, there are the following disadvantages: [0003] First, the button assembly is easy to crack under the action of tension, and the insufficient interference will cause the assembly to fall off; [0004] Second, the button is made of polysulfone plastic, which is not resistant to organic solvents and is prone to quality problems; [0005] Third, the production process of the original bracket is relatively complicated, and the qualified rate of parts is low; [0006] Fourth, the assembly efficiency is relatively low. Contents of the invention [0007] The present invention aims at the shortco...
