[0001] The utility model relates to the technical field related to vibration switches, in particular to a new cylindrical patch vibration switch. Background Art

[0002] The correct name of vibration switch should be called vibration sensor, which is an electronic switch that transmits the sensing result to the circuit device after sensing the vibration force and starts the circuit to work. However, the existing vibration switch has insufficient high temperature resistance, which reduces the application scope of the vibration switch and limits its development and promotion. Therefore, we propose a high temperature patch type vibration switch.

[0003] An existing patch-type vibration switch, patent number CN202321690943.2, includes an upper rubber cover, the bottom of which is sealed and connected to an integrated plastic sheet through a snap-fit ​​mechanism, at least two plug-in holes are opened in the middle of the integrated plastic sheet, conductive hardware for patch-type installation is plugged into the plug-in holes, and a metal conductor placed inside the upper rubber cover is provided on the top of the conductive hardware.

[0004] The above-mentioned vibration switch is provided with a special welding foot, which needs to be aligned during welding, and has a small fault tolerance, and poor contact may occur. At the same time, the vibration switch adopts a rubber cover, and manual assembly is required when assembling the vibration switch, which requires labor costs, and occupies a large space and has low space utilization.

One end of the conductive spring is fixedly connected to the copper cover. The ceramic part is a middle-through structure and is sleeved on the conductive spring.

[0008] To further elaborate, the conductive spring is connected to the copper tube without contact.

[0009] To further explain, the copper cover and the copper tube are both hollow structures, and the copper cover is pressed against the copper tube by the ceramic member to form a receiving chamber for placing the spring.

[0012] To further explain, the diameter of one end of the conductive spring is larger than the diameter of the other end, and the end with the larger diameter is fixedly connected to the copper cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0024] like Figure 1-3 As shown, in this embodiment, a cylindrical new type patch vibration switch is provided, including a ceramic part 1, a conductive spring 2, a copper tube 4 and a copper cover 5. One end of the copper tube 4 and the copper cover 5 are respectively provided with an opening for the ceramic part 1 to be tightly fitted and plugged. The ceramic part 1 is respectively interference fit with the copper tube 4 and the copper cover 5. During the manufacturing process, the openings of the copper tube 4 and the copper cover 5 are placed facing each other and pressed toward the ceramic part 1. The ceramic part 1 is a middle-through structure and is sleeved on the conductive spring 2. Therefore, during installation, the conductive spring 2 passes through the middle of the ceramic part 1 and the conductive spring 2 is arranged inside the copper cover 5 and the copper tube 4 of the ceramic part 1. In order to make the other end of the conductive spring 2 stable and not abut against the copper tube 4, one end of the conductive spring 2 is fixedly connected to the copper cover 5. The principle of the vibration switch is that when affected by some vibrations, the conductive replacement will swing and abut against the copper tube 4 to be turned on. Specifically, the copper cover 5 is turned on by the conductive spring 2 abutting against the copper tube 4. When in use, the copper cover 5 and the copper tube 4 are respectively welded to the positive and negative poles of the circuit board. It is worth mentioning that the utility model is suitable for use in SMT, which refers to the surface assembly technology of electronic circuits, also called surface mounting or surface mounting technology. It is a circuit assembly technology that mounts pinless or short-lead surface mounting components (abbreviated as SMC / SMD, called sheet components in Chinese) on the surface of a printed circuit board (PCB) or other substrate, and assembles them by soldering through reflow soldering or dip soldering.

[0025] In this embodiment, the vibration switch is in a normally open state, in which the conductive spring 2 is not in contact with the copper tube 4, that is, the copper cover 5 is in a non-conductive state with the copper tube 4. To further explain, the copper cover 5 and the copper tube 4 are both hollow structures, and the copper cover 5 is pressed tightly by the ceramic part 1 and the copper tube 4 to form a receiving chamber for placing the spring.

[0026] In this embodiment, the ceramic component 1 is a cylindrical sleeve 6, and the diameter of the sleeve 6 of the ceramic component 1 is slightly smaller than the inner wall diameter of the copper tube 4 and the copper cover 5. The ceramic component 1 is also provided with an insulating flange 3, and the insulating flange 3 is arranged around the side wall of the ceramic component 1. The insulating flange 3 and the ceramic component 1 are integrally formed. The insulating flange 3 can limit the position of the copper tube 4 and the copper cover 5, and the sleeve 6 part is tightly plugged into the copper tube 4 and the copper cover 5; further explained, the ceramic component 1 and the copper tube 4 and the copper cover 5 are all coaxially arranged, the diameter of the insulating flange 3 is the same as the diameter of the outer wall of the copper cover 5 and the copper tube 4, and the ceramic component 1 can isolate the conduction between the copper tube 4 and the copper cover 5.

[0027] To further illustrate, the diameter of one end of the conductive spring 2 is larger than that of the other end, and the end with the larger diameter is fixedly connected to the copper cover 5. One end of the conductive spring 2 can be fixedly connected to the copper cover 5 in advance by conventional means including welding and bonding, and then after the conductive spring 2 passes through the ceramic part 1, the copper tube 4 and the copper cover 5 are tightly fitted and crimped with the ceramic part 1. The material made of the ceramic part 1 is ceramic to replace the previous epoxy resin material, and the ceramic part 1 can still work normally at a high temperature of 200-270 degrees.

[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
