Description

Technical Field

[0001] The utility model relates to the technical field of anti-vibration mechanisms, in particular to an anti-vibration connector component. Background Art

[0002] Pogo pins are a type of precision connector widely used in consumer electronics. They consist of three to six parts: a needle, an inner needle tube, a spring, a mushroom head, and an outer needle tube. Nickel and gold plating on the surface achieve low resistance, oxidation resistance, and scratch resistance. Various internal structural designs ensure stable and reliable connections between parts, allowing for the transmission of current and signals. In projects with high-frequency vibration, such as audio equipment, drones, and automotive applications, connectors must withstand high currents and withstand high-frequency vibration and impact testing.

[0003] Existing reeds are generally cat-paw-shaped, with a cylindrical upper end and a conical lower end. When the central shaft is inserted, it is connected to the lower end of the reed. In order to reserve some space for expansion and contraction, such products are generally designed to be long and cannot adapt to shorter usage spaces. Therefore, we propose an anti-vibration connector assembly to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it comprises an outer sleeve, a second mounting groove is provided on the inner side of the outer sleeve, an inner sleeve is inserted into the inner side of the second mounting groove, a limiting block is provided on the inner side of the inner sleeve, a mushroom head is integrally formed on the limiting block, and the mushroom head extends to the outside of the inner sleeve, a buffer shaft is integrally formed on the end of the limiting block away from the mushroom head, an arc-shaped mounting groove is symmetrically provided on the end of the buffer shaft away from the limiting block, an arc-shaped spring sheet is provided on the inner side of the arc-shaped mounting groove, a first mounting groove is provided on the inner side of the outer sleeve and away from the mushroom head, a buffer tube is provided on the inner side of the first mounting groove, limiting grooves are symmetrically provided on the buffer tube, and the inner side of the inner sleeve and the position A high-performance spring is provided on the outside of the buffer shaft, and a supporting groove is provided on the inner side of the outer sleeve and near the buffer sleeve; the outer sleeve is used for external protection of the entire device, and the second mounting groove is used to limit the mushroom head and the limit block during use, so that the device maintains a stronger anti-vibration effect during use, prevents the mushroom head from being separated from the inner sleeve during use, and can ensure the anti-vibration effect of the mushroom head during the process of achieving the anti-vibration effect. The buffer shaft is used as the anti-vibration center axis of the device. When the device is used and vibration occurs, the buffer shaft will continuously vibrate in a small range on the inside of the inner sleeve, so that the user can make a shorter spring needle and reduce the space length used by the device.

[0006] As a preferred solution, the arc-shaped spring piece is loosely matched with the limiting groove; the arc-shaped installation groove is used to limit the arc-shaped spring piece, and the arc-shaped spring piece can be moved from the lower end to the upper end of the limiting groove. At this time, only a smaller length space is required to meet the functional application.

[0007] As a preferred solution, a second bending portion is integrally formed on the outer sleeve near one end of the mushroom head, and a first bending portion is integrally formed on the inner sleeve near one end of the mushroom head, and the first bending portion is in fit with the second bending portion; the second bending portion cooperates with the first bending portion to achieve an anti-vibration effect in cooperation with the mushroom head when vibration occurs.

[0008] As a preferred solution, a first bending opening is provided on the inner side of the inner sleeve near one end of the mushroom head; the first bending opening can enhance the cooperation effect between the inner sleeve and the limit block, thereby improving the anti-vibration performance of the device.

[0009] As a preferred solution, the limit block is provided with a second bending opening near one end of the mushroom head; when vibration occurs, the cooperation between the first bending opening and the second bending opening can make the contact point between the limit block and the inner sleeve more uniform, thereby preventing the limit block from being damaged when subjected to force.

[0010] As a preferred solution, the mushroom head is provided with an arc-shaped section at one end away from the limit block; the arc-shaped section is used as the contact point for the device to prevent vibration. The spherical surface of the arc-shaped section has a large contact area with the structure, and the force is transmitted evenly, thereby avoiding damage to the structure and improving the overall seismic performance. The spherical design enables the vibration isolation component to bear pull-out force, pressure and shear force in any direction in multiple directions, thereby ensuring the stability of the structure in a complex stress environment.

[0011] As a preferred solution, the height of the buffer tube is less than 5 mm, which enables the device to achieve the best anti-vibration effect in a smaller length space.

[0012] As a preferred solution, the high-performance spring is located on the inner side of the inner sleeve, and its two ends are respectively abutted against the outer sleeve and the limit block; there is no need to add redundant components to limit the high-performance spring, which simplifies the installation of the high-performance spring and can also ensure the anti-vibration effect of the device.

[0013] As a preferred solution, the supporting groove is a conical groove; the supporting groove is a conical groove, which can make the contact points between the buffer shaft and the supporting groove more dispersed, making the force between the two more uniform.

[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0015] The outer sleeve of this device is used for the external protection of the entire device and is in direct contact with the vibrating part. The second mounting groove opened on the inner side of the outer sleeve is used to load the inner sleeve. The inner sleeve inserted into the inner side of the second mounting groove is used to limit the mushroom head and the limit block during use, so that the device maintains a stronger anti-vibration effect during use. The limit block set on the inner side of the inner sleeve is used to limit the mushroom head to prevent the mushroom head from separating from the inner sleeve during use, and can ensure the anti-vibration effect of the mushroom head during the process of achieving the anti-vibration effect. A mushroom head is integrally formed on the limit block, and the mushroom head extends to the outside of the inner sleeve. A buffer shaft integrally formed at the end of the limit block away from the mushroom head is used as the anti-vibration center axis of this device. When the device is used and vibration occurs, the mushroom head will drive the buffer shaft to continuously vibrate in a small range on the inner side of the inner sleeve, so that the user can make a shorter spring needle and reduce the space length used by this device. The arc-shaped mounting groove symmetrically opened at the end of the buffer shaft away from the limit block is used The arc spring piece is limited in position by the arc spring piece. When vibration occurs, the arc spring piece can be moved from the lower end of the buffer cylinder to the upper end because the buffer shaft has been limited in position in the inner sleeve. At this time, only a smaller length space is needed to meet the functional application. An arc spring piece is provided on the inner side of the arc mounting groove. The first mounting groove opened on the inner side of the outer sleeve and away from the end of the mushroom head cooperates with the buffer shaft to drive the arc spring piece to limit the vibration range of the mushroom head. The buffer cylinder provided on the inner side of the first mounting groove is used to cooperate with the buffer shaft to drive the arc spring piece to perform a small range of displacement. Through the limiting grooves symmetrically opened on the buffer cylinder, the vibration range of the arc spring piece driven by the buffer shaft is within the length space limit of the limiting groove. The high-performance spring provided on the inner side of the inner sleeve and on the outer side of the buffer shaft is used to buffer the vibration of the buffer shaft driven by the mushroom head. The supporting groove opened on the inner side of the outer sleeve and close to the buffer cylinder is used to limit the buffer shaft. When vibration occurs, the buffer shaft continuously displaces on the inner side of the inner sleeve. The longest displacement range, that is, the distance of the buffer shaft against the supporting groove;

[0016] Since the arc-shaped spring piece of this device has been limited in position in the inner sleeve, the arc-shaped spring piece can be moved from the lower end to the upper end of the buffer cylinder. In this case, only a smaller length space is required to meet the functional application, and a shorter spring needle can be manufactured. The size and total length are universal with existing supplied products, and it has strong interchangeability.
