Description

Technical Field

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

[0002] Spring pins are a kind of precision connector widely used in consumer electronic products. They are composed of 3 to 6 parts including needle, inner needle tube, spring, mushroom head and outer needle tube. The surface is nickel-plated and gold-plated to achieve low resistance, oxidation resistance and scratch resistance. Various internal structural designs ensure stable and reliable connection between parts, and play the role of transmitting current and signals. In some projects with high-frequency vibration, such as audio, drones, and some connectors required in automobiles, they not only bear large currents, but also have high-frequency vibration and impact test requirements.

[0003] The existing reed is generally a cat's claw-shaped structure, with a cylindrical upper end and a conical lower end. When the central axis is inserted, it is connected to the lower end of the reed. In order to reserve a part of the expansion space, such products are generally designed to be longer in length and cannot adapt to a shorter usage space; therefore, we propose an anti-vibration connector assembly to solve the above problems. Summary of the invention

[0004] In view of this, the main purpose of the missing pin of the present invention is to provide a vibration-proof connector assembly, which serves to solve the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it includes 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 located at A high-performance spring is arranged on the outside of the buffer shaft, and a supporting groove is opened 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 can maintain a stronger anti-vibration effect during use, prevent the mushroom head from separating from the inner sleeve during use, and 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 in use 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 clearance-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 needed to meet the functional application.

[0007] As a preferred solution, a second bending portion is integrally formed on the outer sleeve and close to one end of the mushroom head, and a first bending portion is integrally formed on the inner sleeve and close to one end of the mushroom head, and the first bending portion is in contact 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, a second bending opening is provided at one end of the limit block near the mushroom head; when vibration occurs, the contact point between the limit block and the inner sleeve can be made more uniform through the cooperation of the first bending opening and the second bending opening, thereby preventing the limit block from being damaged when subjected to force.

[0010] As a preferred solution, an arc-shaped section is provided at one end of the mushroom head away from the limit block; the arc-shaped section is used as the contact point of the device for vibration isolation, and 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 surface 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 under complex stress environments.

[0011] As a preferred solution, the height of the buffer tube is less than 5 mm, which enables the device to exert 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 abutting groove is a conical groove; the abutting groove is a conical groove, which can make the contact points between the buffer shaft and the abutting groove more dispersed, so that the force between the two is 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 it mainly has the following advantages:

[0015] The device uses an outer sleeve for overall external protection of the device and is in direct contact with the vibrating member. The second mounting groove provided on the inner side of the outer sleeve is used for loading the inner sleeve. The inner sleeve plugged into the inner side of the second mounting groove is used for limiting the mushroom head and the limit block during use, so that the device maintains a stronger anti-vibration effect during use. The limit block provided on the inner side of the inner sleeve is used for limiting the mushroom head to prevent 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. 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 one end of the limit block away from the mushroom head is used as the anti-vibration center axis of the device. When the device is in use and vibrates, the mushroom head drives 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 the device. The arc-shaped mounting groove symmetrically provided at one end of the buffer shaft away from the limit block is used for The arc spring piece is limited in position. When vibration occurs, the arc spring piece can be moved from the lower end of the buffer tube to the upper end because the buffer shaft has been limited in position in the inner sleeve. At this time, only a small length space is needed to meet the functional application. An arc spring piece is arranged 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 tube arranged 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 tube, 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 arranged 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 abutting groove opened on the inner side of the outer sleeve and close to the buffer tube 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 abutting against the abutting groove;

[0016] Since the buffer shaft of the device has been limited in position in the inner sleeve, the arc-shaped spring piece of the device can be moved from the lower end to the upper end of the buffer tube. At this time, only a smaller length space is needed 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 replaceability.
