Description

Technical Field

[0001] This utility model relates to the technical field of high overload switches, and in particular to a high overload miniature power-on switch. Background Technology

[0002] With the development of modern warfare, the requirements for weapon systems have become more complex and diverse. Therefore, weapon systems are evolving towards intelligence, and the energy consumption of circuits is constantly increasing. This necessitates an increase in the energy of the power supply batteries. Furthermore, with advancements in the storage life of high-energy-storage batteries such as lithium batteries, more and more weapon power supply modules are being replaced from traditional magneto and thermal batteries with lithium batteries and other power sources that offer short activation times and high energy storage. The power supply batteries and circuits in weapons should be disconnected during storage and maintenance periods, and reliably connected after projectile launch. Currently, most power switches require an exposed pressing mechanism to activate, necessitating an additional mechanism for the projectile or fuse to press the switch. This results in a larger overall structure, and such switches are easily damaged under high overload conditions, leading to unreliable connection. Therefore, designing a small, high-overload power switch is crucial. Utility Model Content

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0018] like Figures 1-2 As shown, a high overload miniature power-connecting switch includes a power-connecting switch device body 1. The power-connecting switch device body 1 includes an insulating sleeve 2, an insulating cover 3, a contact block 4, a spring, a contact piece, an insulating base 5, and a pressure cap 6. The contact piece is provided with a first contact piece 7 and a second contact piece 8. The spring piece is stamped into a V-shaped structure.

[0019] In this embodiment, the spring is provided with a first spring 9 and a second spring 10. The insulating cover 3, the insulating sleeve 2 and the insulating base 5 form an internal cavity structure. The first spring 9, the second spring 10 and the contact block 4 are disposed inside the cavity structure. The outer side wall of the insulating sleeve 2 is provided with an annular groove 11. The pressure cap 6 is disposed above the insulating cover 3 and the insulating sleeve 2, and the end of the pressure cap 6 is embedded in the annular groove 11. The first contact 7 and the second contact 8 are both Z-shaped structures. The first contact 7 includes a first transverse component 12, which is located at the top of the insulating base 5 to facilitate contact between the first transverse component 12 and the contact block 4 in the energized state. The other end of the first contact 7 extends out of the insulating base to facilitate welding and assembly. One end of the second contact 8 is embedded between the insulating cover 3 and the insulating base 5, and the other end extends out of the insulating base to facilitate welding and assembly. One end of the first spring 9 is connected to the second contact 8, and the other end is embedded in the contact block 4. One end of the first contact 7 is embedded in the contact block 4, and the other end is embedded in the insulating cover 3.

[0020] In this embodiment, the bottom of the contact block 4 is arc-shaped. The contact block 4, the first spring 9, the second spring 10, the first contact piece 7 and the second contact piece 8 are all made of conductive metal material. The insulating sleeve 2, the insulating cover 3 and the insulating base 5 are all made of insulating material.

[0021] In this embodiment, the first contact 9 and the second contact 10 are made of elastic metal material, and the first contact 7 and the second contact 8 do not contact each other.

[0022] In this embodiment, after the first contact piece 7 and the second contact piece 8 are assembled, they are pressed down by the insulating cover 3 and then fixed by riveting with the pressure cap 6. The whole structure is firm and reliable and has high assembly efficiency.

[0023] The working principle of this utility model is as follows: In the initial state, the first contact 7 and the second contact 8 are not in contact, and the power switch is in the off state; under high overload, the contact block 4 moves downward, causing the first spring 9 and the second spring 10 to flip. After flipping, the contact block 4 presses against the first horizontal component 12. Since the first spring 9 and the second spring 10 are arched downward, they remain in the current state. At this time, the first contact 7 and the second contact 8 are connected to the contact block 4 through the second spring 10, and the switch is in the on state. When in use, the switch can be fixed inside the structural component or soldered onto the circuit board, and the assembly method is flexible.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
