Description

Technical Field

[0001] The invention relates to a novel universal acceleration normally-open self-locking switch, belonging to the technical field of acceleration switches. Background Art

[0002] With the rapid development of modern industry and technology, the demand for precision control and automation is growing. In many automated control systems, the accelerometer switch is a key component whose performance directly affects the response speed and stability of the system. However, there are many limitations in the existing accelerometer switches, which limit their large-scale application in low-cost fields.

[0003] Currently, acceleration switches are mainly used in the fields of machinery, electronics, automobiles, military, aerospace, etc., which have high technical requirements for acceleration switches, resulting in complex structures, complex manufacturing processes, large sizes, high costs, etc., which are not suitable for use in low-cost, large-scale manufactured consumer products.

[0004] Most of the existing acceleration switches on the market are based on traditional mechanical or electromagnetic principles, or on MEMS with complex processes. These principles cannot meet the performance requirements in low-cost large-scale consumer application scenarios and are not suitable for large-scale consumer applications.

[0005] For acceleration switches, in some occasions, only a one-way switch is sufficient, while in other occasions, a three-dimensional multi-directional acceleration switch is required. Summary of the invention

[0006] The purpose of the present invention is to provide a novel universal acceleration normally open self-locking switch to solve the above technical problems.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is: A novel universal acceleration normally open self-locking switch comprises a conductor shell, an insulating core and a conductor core; the insulating core is located in the conductor shell; the conductor core is located in the insulating core, and a cavity is formed between the outer surface of the conductor core and the inner surface of the insulating core; six conductor moving contacts are arranged on the outer side of the surface of the conductor core in a three-dimensional coordinate system, and six guide grooves are arranged on the insulating core correspondingly; the conductor moving contact is arranged in the guide groove; an elastic wire is connected to the surface of the conductor core, and the elastic wire extends outward through the insulating through holes of the insulating core and the conductor shell; the conductor shell and the elastic wire are respectively connected to outer leads for use in conjunction with each other; the conductor core is fixed by the static friction between the conductor moving contact and the guide groove, and during the acceleration increase process, the conductor core can move through the cooperation of the conductor moving contact and the guide groove, and the conductor moving contact and the conductor shell can be adsorbed together.

[0008] A further improvement of the technical solution of the present invention is that the insulating core is attached to the inner surface of the conductor shell.

[0009] A further improvement of the technical solution of the present invention is that the conductor moving contact is made of magnetic material, and the conductor shell is made of ferromagnetic material.

[0010] A further improvement of the technical solution of the present invention is that the conductor moving contact is made of ferromagnetic material, and the conductor shell is made of magnetic material.

[0011] Due to the adoption of the above technical solution, the technical effects achieved by the present invention are as follows: The present invention is a novel universal acceleration normally open self-locking switch, which is provided with a conductor shell, an insulating core and a conductor inner core. The circuit is isolated by attaching the insulating core to the conductor shell and the conductor inner core. At the same time, a guide groove is arranged on the insulating core, and a conductor moving contact is arranged on the surface of the conductor inner core. The stable positioning of the conductor inner core can be achieved through the cooperation of the guide groove and the conductor moving contact. When the acceleration increases to a certain value, the conductor moving contact can move relative to the guide groove together with the conductor inner core, and then the conductor moving contact and the conductor shell are adsorbed and locked to realize that the switch changes from an open circuit state to an open circuit state.

[0012] The acceleration switch of the present invention is a disposable switch. Since it is completely formed by mechanical structures using parts and has a relatively simple structure, it has the advantages of being easy to process and having low processing costs, and is suitable for large-scale production and use. The acceleration switch is suitable for use in situations where a normally open switch is required, and can achieve good use effects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0016] The invention discloses a novel universal acceleration normally open self-locking switch, which belongs to an acceleration switch and can be excited when acceleration is generated in any direction, thereby changing the on-off state of the switch.

[0017] like Figure 1 As shown, the acceleration switch includes a conductor shell 1, an insulating core 2 and a conductor core 3. The conductor shell 1 is made of a conductor material, the insulating core 2 is made of an insulating material, and the conductor core 3 is made of a conductor material. The three are in a set structure. The insulating core 2 is located inside the conductor shell 1; the conductor core 3 is located inside the insulating core 2. In the initial state, the conductor core 3 is located at the center of the insulating core 2, and there is a cavity 5 between the outer surface of the conductor core 3 and the inner surface of the insulating core 2.

[0018] Six conductor moving contacts 4 are arranged on the outer surface of the conductor core 3, and the six conductor moving contacts 4 are long strip structures. The six conductor moving contacts 4 are distributed and arranged in a three-dimensional coordinate system, that is, in an XYZ three-axis coordinate system. Two conductor moving contacts 4 form a group and form a straight line, and the conductor moving contacts 4 in a group are perpendicular to other conductor moving contacts 4 in a group. At the same time, in order to guide its moving direction, six guide grooves 6 are arranged on the insulating core 2. During assembly, the six conductor moving contacts 4 are respectively located in the corresponding guide grooves 6. The conductor core 3 is located at the center position surrounded by the inner ends of the six conductor moving contacts 4. There is no connection relationship between the conductor core 3 and the six conductor moving contacts 4, but only a contact relationship. The six conductor moving contacts 4 support the conductor core 3; the static friction between the conductor moving contacts 4 and the guide grooves 6 can make the conductor core 3 in a stable state.

[0019] In addition, an elastic wire 7 is connected to the surface of the conductor core 3. The elastic wire 7 is made of a conductor material and is used as a wire. The other end of the elastic wire 7 passes through the insulating core 2 and the insulating through hole 8 of the conductor shell 1 in turn and then extends outward to the outside of the conductor shell 1. An outer lead 9 is connected to the outermost end of the elastic wire 7, and an outer lead 9 is also connected to the outer surface of the conductor shell 1. These two outer leads 9 are connected to the external circuit to achieve control of the circuit.

[0020] When the acceleration switch is in use, the initial state is an unactivated state. When the acceleration increases to a certain value, the thrust formed by the conductor core 3 can overcome the static friction between the conductor movable contact 4 and the guide groove 6, and the conductor core 3 can push the conductor movable contact 4 to move, and the conductor movable contact 4 moves linearly under the cooperation of the conductor movable contact 4 and the guide groove 6 until the conductor movable contact 4 contacts the conductor housing 1, so that the switch state changes to the on state, and the conductor movable contact 4 and the conductor housing 1 can be adsorbed together to form a self-locking effect.

[0021] In a specific implementation, the insulating core 2 is usually attached to the inner surface of the conductor shell 1 .

[0022] The conductor movable contact 4 and the conductor housing 1 can be adsorbed together, so the conductor movable contact 4 and the conductor housing 1 are made of a combination of magnetic material and ferromagnetic material. Usually, the conductor movable contact 4 is made of a magnetic material, and the conductor housing 1 is made of a ferromagnetic material. Alternatively, the conductor movable contact 4 is made of a ferromagnetic material, and the conductor housing 1 is made of a magnetic material.

[0023] When the acceleration switch is in use, it is normally open in the initial state, and the switch is in the disconnected state. When acceleration is generated in a certain direction, the conductor core 3 generates a movement trend opposite to the acceleration direction due to inertia, thereby forming a thrust on the conductor movable contact 4; when the acceleration gradually increases, the thrust formed by the conductor core 3 on the conductor movable contact gradually increases; when the acceleration increases to a certain value, the thrust formed by the conductor core 3 on the conductor movable contact 4 can overcome the static friction between the conductor movable contact 4 and the guide groove 6, and the conductor core 3 can push one or two conductor movable contacts 4 to move. When the conductor movable contact 4 contacts and the conductor shell 1 are locked by adsorption, the switch changes from the disconnected state to the connected state. At this time, the circuit in the connected state is formed by the elastic wire 7, the conductor core 3, the conductor movable contact 4, and the conductor shell 1. If the acceleration direction is the same as one group of conductor movable contacts 4, only the conductor movable contacts 4 of this group move. If the acceleration direction is not in the same direction as any one of the conductor movable contacts 4, the thrust generated by the conductor core 3 will push the conductor movable contacts 4 of the two groups to move, and the movement of the conductor movable contacts 4 is limited by the guide groove 6 and can only move along the direction of the guide groove 6. The thrust direction is between the two guide grooves 6, and at this time, the conductor movable contacts 4 of the two groups move.

[0024] The present invention is a novel universal acceleration normally open self-locking switch, which realizes the stable fixation of the conductor core through the cooperation of the guide groove and the conductor moving contact, and when the acceleration increases to a certain value, the conductor moving contact can move relative to the guide groove together with the conductor core, and then the conductor moving contact and the conductor shell are adsorbed and locked to realize the switch changing from an open circuit state to a closed circuit state.
