Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to a shock-resistant and anti-loosening terminal block. Background Technology

[0002] Terminal blocks, as key components for electrical connections, are widely used in industrial control, rail transportation, new energy equipment and other fields. The stability of their connections is directly related to the safe operation of the entire electrical system. In actual use scenarios, many devices are in a vibrating environment for a long time, such as control boxes next to motors and electrical cabinets in rail transit vehicles. Vibration can easily cause the connection between the terminal block and the wire or external equipment to loosen, which can lead to problems such as poor contact, arcing or even equipment failure. Therefore, the requirements for vibration resistance and anti-loosening performance are increasing.

[0003] A patent document with publication number CN223285290U discloses a quick-clamping shock-resistant terminal box, relating to the field of terminal boxes. It includes a main body and a cover at the top of the main body. Marking base holders are located on the left and right sides of the top of the main body, and a wire inlet hole is located on the outer side of the main body. A nameplate is located at the front of the main body, and a conductive component is located inside the main body. A marking strip holder is fixedly installed on the inner wall of the upper end of the cover. In this quick-clamping shock-resistant terminal box, the cover, made of PA66 material, provides insulation. The marking base holders are located on the outer side of the upper end of the main body, allowing for the installation of marking bases. The wire inlet hole is used to hold wires. The nameplate at the front of the main body indicates the quantity of products. The operating hole facilitates wire passage and allows for easy classification of wires, simplifying wiring and maintenance.

[0004] However, in the above-mentioned solutions and existing technologies, the terminal block is prone to swaying synchronously with the equipment vibration in a vibration environment. Its internal wire clamping structure and external connection structure are difficult to offset the impact force brought by vibration. After long-term use, the clamping force between the wire and the terminal is easy to decay, which may not be able to continuously guarantee a stable connection state and make it difficult to meet the stringent requirements for connection reliability in high vibration scenarios.

[0005] Therefore, this utility model proposes a shock-resistant and anti-loosening terminal block to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a shock-resistant and anti-loosening terminal block to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant and anti-loosening terminal block, comprising a base, a snap-fit ​​plate, and a mounting base, wherein the snap-fit ​​plate is fixedly disposed on the upper center of the base, and mounting bases are evenly disposed on the base; The mounting base is provided with a sliding component, a buffer component, and a fixing component. The sliding component is mounted on the mounting base, the buffer component is mounted on the sliding component, and the fixing component is mounted on the buffer component.

[0008] Preferably, the sliding seat in the sliding assembly is slidably engaged in the mounting base, and sliding protrusions are provided at both ends of the sliding seat, which are adapted to be slidably engaged in the sliding groove.

[0009] Preferably, the sliding groove in the sliding assembly is fixedly disposed on the mounting plates at both ends of the mounting base, and the mounting plates are snapped and fixed on the snap-fit ​​plate.

[0010] Preferably, the upper mounting port of the buffer assembly is located in the middle of the sliding seat, and the middle of the mounting seat is provided with a lower mounting port. A buffer protrusion is fixedly provided in the middle of the upper mounting port and the lower mounting port.

[0011] Preferably, one end of the telescopic rod in the buffer assembly is fixedly disposed on the inner side of the sliding seat, and the other end of the telescopic rod is fixedly disposed on the inner side of the mounting seat, and a spring is fixedly sleeved on the outside of the telescopic rod.

[0012] Preferably, the retaining pin in the retaining component is sleeved on the fixing plate, and the retaining pin is threadedly connected to the sliding seat and the mounting seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: through the coordinated cooperation of the sliding component, the buffer component, and the fixing component, the anti-vibration and anti-loosening performance of the terminal block is effectively improved. The sliding engagement of the sliding seat and the sliding groove in the sliding component guides the component to move slightly along a fixed trajectory to avoid misalignment. The telescopic rod and spring of the buffer component absorb the vibration impact force, and the buffer protrusions of the upper and lower mounting ports weaken the vibration transmission and reduce stress concentration. The fixing component forms a stable lock between the sliding seat and the mounting seat and the fixing plate through the threaded connection of the fixing pin. The combination of the three components enables the terminal block to buffer the impact and maintain structural stability in a vibration environment, avoid the attenuation of wire clamping force, and ensure the reliability and safety of electrical system connection.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0017] Example 1: Please refer to Figures 1 to 2 A shock-resistant and anti-loosening terminal block includes a base 1, a snap-fit ​​plate 2, and a mounting base 3. The snap-fit ​​plate 2 is fixedly installed in the middle of the base 1, and the mounting bases 3 are evenly distributed on the base 1. The mounting base 3 is provided with a sliding component 4, a buffer component 5, and a fixing component 6. The sliding component 4 is installed on the mounting base 3, the buffer component 5 is installed on the sliding component 4, and the fixing component 6 is installed on the buffer component 5.

[0018] The sliding seat 401 in the sliding assembly 4 is slidably engaged in the mounting base 3. Sliding protrusions 402 are provided at both ends of the sliding seat 401, and the sliding protrusions 402 are adapted to be slidably engaged in the sliding groove 403.

[0019] The sliding groove 403 in the sliding component 4 is fixedly installed on the mounting plate 404 at both ends of the mounting base 3, and the mounting plate 404 is snapped and fixed on the snap-fit ​​plate 2.

[0020] In use, first, the mounting plate 404 and the snap-fit ​​plate 2 are snapped together to ensure that the installation position of the sliding groove 403 is stable. The sliding protrusions 402 at both ends of the sliding seat 401 are always precisely fitted and snapped into the sliding grooves 403 on the mounting plate 404. When the equipment vibrates, the sliding seat 401 can make a slight linear displacement along the sliding groove 403. The matching structure of the sliding protrusions 402 and the sliding groove 403 can strictly limit the displacement trajectory and avoid lateral misalignment or offset between the sliding seat 401 and the mounting seat 3. This trajectory guidance lays the foundation for the stable operation of the subsequent buffer component 5, prevents the failure of the anti-vibration structure due to component misalignment, and ensures that the core components inside the terminal block maintain a relatively regular movement state in the early stage of vibration, providing a stable premise for impact buffering.

[0021] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The upper mounting port 501 in the buffer assembly 5 is located in the middle of the sliding seat 401, and the lower mounting port 502 is located in the middle of the mounting seat 3. The upper mounting port 501 and the lower mounting port 502 are fixedly provided with buffer protrusions 503 in the middle.

[0022] One end of the telescopic rod 504 in the buffer assembly 5 is fixedly installed inside the sliding seat 401, and the other end of the telescopic rod 504 is fixedly installed inside the mounting seat 3. A spring 505 is fixedly sleeved on the outside of the telescopic rod 504.

[0023] In use, after the sliding component 4 is assembled, the buffer component 5 is already in the preset working state. When the vibration impact force is applied to the terminal block, the displacement of the sliding seat 401 along the sliding groove 403 will drive the telescopic rod 504 to extend and retract. The spring 505 fixedly sleeved on the telescopic rod 504 will undergo elastic deformation. Through the deformation process, the kinetic energy generated by the vibration is converted into elastic potential energy, thereby initially absorbing the vibration impact force. At the same time, the upper mounting port 501 in the upper middle part of the sliding seat 401 and the lower mounting port 502 in the middle part of the mounting seat 3 are relatively close to each other, and the buffer protrusion 503 in the middle of the two are pressed and contacted with each other, further weakening the transmission of vibration to the core wiring part of the terminal block. The telescopic rod 504 can effectively prevent the spring 505 from bending or shifting when deformed, ensuring that the buffer force is stably transmitted along the axial direction, reducing the stress concentration phenomenon at the connection between the mounting seat 3 and the sliding seat 401, avoiding damage to the components due to excessive local stress, and ensuring the long-term stable anti-vibration effect of the buffer component 5.

[0024] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The securing pin 601 in the securing component 6 is sleeved on the fixing plate 602, and the securing pin 601 is threadedly connected to the sliding seat 401 and the mounting seat 3.

[0025] In use, after the sliding assembly 4 and the buffer assembly 5 are assembled, the fixing plate 602 is placed over the connection between the sliding seat 401 and the mounting seat 3, so that the through hole on the fixing plate 602 is precisely aligned with the threaded hole on the sliding seat 401 and the mounting seat 3. Then, the locking pin 601 is passed through the through hole of the fixing plate 602 and screwed clockwise into the threaded hole of the sliding seat 401 and the mounting seat 3 until the fixing plate 602 is tightly attached to the surface of the component, thus completing the locking and fixing of the locking assembly 6. In a vibration environment, the threaded connection structure of the locking pin 601 can provide a continuous and stable locking force, effectively preventing the sliding seat 401 and the mounting seat 3 from loosening and separating due to long-term vibration. The fixing plate 602 increases the contact area of ​​the locking part, so that the locking force is evenly distributed on the sliding seat 401 and the mounting seat 3, avoiding excessive local locking pressure that could damage the component.
