Description

Technical Field

[0001] This utility model relates to the field of magnetic latching relay technology, and in particular to a magnetic latching relay housing with shock resistance. Background Technology

[0002] As a key component widely used in power systems and industrial automation control equipment, the operational stability of magnetic latching relays directly affects the operational safety and reliability of the entire system. In practical applications, magnetic latching relays not only need to withstand complex and changing electrical environments, but also often face mechanical vibrations and impacts during transportation, installation, and operation. These external mechanical factors can easily cause the internal magnetic circuit structure of the relay to shift, poor contact between the moving and stationary contacts, or even mechanical damage to key components, thereby affecting its normal operating performance and potentially leading to system failures or safety accidents in severe cases.

[0003] Currently, most magnetic latching relays on the market use a single-layer plastic or metal housing structure. Although they have certain protection levels and cost advantages, they are significantly lacking in shock resistance. Such housing structures usually lack effective buffer energy absorption design, making it difficult to effectively absorb or disperse impact energy from the outside. When subjected to strong vibration or impact, they are very likely to directly transfer stress to internal components, thereby causing relay failure.

[0004] Therefore, there is an urgent need to provide a magnetic latching relay housing with a multi-layered shock-resistant protection structure. Utility Model Content

[0005] In order to overcome the shortcomings of existing magnetic latching relay housings which are single-layer structures and have difficulty in effectively resisting impact and absorbing external impact energy, this utility model provides a magnetic latching relay housing with a multi-layer impact-resistant protection structure.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a magnetic latching relay housing with impact resistance, comprising a magnetic latching relay body, a first housing and a second housing fitted around the magnetic latching relay body, the first housing and the second housing being hinged together, a handle fixedly attached to the top of both the first housing and the second housing, an inner buffer pad provided on the inner wall of both the first housing and the second housing, an outer impact plate provided on the outer wall of both the first housing and the second housing, and multiple heat dissipation holes in the same position on both sides of the first housing, the second housing, the inner buffer pad, and the outer impact plate.

[0007] Optionally, an observation plate is embedded in the middle of both the first outer shell and the second outer shell.

[0008] Optionally, a support plate is fixedly connected to the top of the first housing by screws, and a plurality of wire loops are evenly spaced along the width direction on the top of the support plate.

[0009] Optionally, a sponge pad is provided on the inner wall of the wire harness ring.

[0010] Optionally, a first magnetic strip is embedded on both sides of the first housing, and a second magnetic strip is embedded on both sides of the second housing.

[0011] Optionally, a rubber ring is embedded at the middle position of the top of the first housing and the second housing.

[0012] Optionally, both the first housing and the second housing are provided with anti-slip pads at their bottoms.

[0013] Compared with the prior art, the present invention has the following technical effects: 1. By combining the outer impact plate, the inner buffer pad and the first and second shells, a multi-level impact-resistant structure is formed. The outer impact plate enhances the overall rigidity and compressive strength of the shell, preventing deformation or breakage caused by external impact, while the inner buffer pad can effectively absorb the vibration energy transmitted to the internal components and protect the relay body from damage.

[0014] 2. Embedded rubber rings provide a channel for cables to pass through. In addition, the evenly distributed cable tie rings on the support plate, together with the sponge pads, facilitate the orderly arrangement and fixation of incoming and outgoing cables, which reduces the risk of cable tangling and also reduces the probability of wear caused by friction.

[0021] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0022] Example 1: Please refer to Figures 1-3 A shock-resistant magnetic latching relay housing includes a magnetic latching relay body 5. A first housing 1 and a second housing 2 are fitted around the magnetic latching relay body 5. The first housing 1 and the second housing 2 are hinged together, allowing them to be opened and closed for easy maintenance or replacement of the internal relay body. A handle 3 is fixed to the top of both the first housing 1 and the second housing 2 for easy opening and closing by the operator. Inner buffer pads 4 are provided on the inner walls of both the first housing 1 and the second housing 2 to absorb the energy transmitted to the relay body from external vibrations or impacts, thereby protecting its internal precision components from damage. Outer impact plates 6 are provided on the outer walls of both the first housing 1 and the second housing 2, and the outer impact plates 6 are made of a material with certain strength and toughness. To enhance the overall mechanical strength and impact resistance of the housing and prevent deformation or breakage due to external impact, four heat dissipation holes 7 are provided on the front and rear sides of the first housing 1, the second housing 2, the inner buffer pad 4, and the outer impact plate 6, respectively, to ensure the connectivity of the heat dissipation channel and ensure that internal heat can be discharged in time, avoiding the impact of temperature rise on the normal operation performance of the relay. An observation plate 8 is embedded in the middle of the first housing 1 and the second housing 2, allowing the user to visually inspect the operating parameters of the magnetic latching relay body 5 without opening the housing. Anti-slip pads 16 are provided at the bottom of the first housing 1 and the second housing 2 to increase the friction between the housing and the mounting surface and prevent displacement or tilting caused by external vibration or mechanical impact.

[0023] During use, the magnetic latching relay body 5 is enclosed by the first outer shell 1 and the second outer shell 2, forming a protective structure. When the equipment is subjected to mechanical impact and vibration during transportation, installation, or operation, the outer impact plate 6, located on the outside of the outer shell, serves as the first line of defense, effectively dispersing and absorbing large impact forces from the outside, improving the overall rigidity and compressive strength of the outer shell, and preventing structural damage to the outer shell. Meanwhile, the inner buffer pad 4, set on the inner wall of the outer shell, is in close contact with the surface of the magnetic latching relay body 5, possessing good elasticity and shock absorption performance. It can absorb part of the external vibration or impact energy before it is transmitted to the internal components, thereby avoiding faults such as magnetic circuit misalignment and contact loosening. Thus, through the triple design of the outer impact plate 6, the outer shell, and the inner buffer pad 4, effective protection of the magnetic latching relay body 5 is achieved under complex working conditions, while also possessing excellent impact resistance, good heat dissipation capacity, and convenient operation and maintenance characteristics.

[0024] Example 2: Based on Example 1, please refer to... Figure 4 and Figure 5 The top of the first outer shell 1 is fixedly connected to a support plate 9 by screws 11. Six cable tie rings 10 are evenly spaced along the width direction on the top of the support plate 9 for orderly arrangement and fixation of incoming and outgoing cables. The inner wall of the cable tie ring 10 is provided with a sponge pad 12 to provide buffer protection during cable insertion, avoid damage to the cable sheath due to friction or compression, and enhance the stability of cable fixation. A rubber ring 15 is embedded in the middle of the top of the first outer shell 1 and the second outer shell 2. The rubber ring 15 has good elasticity and compression resilience, allowing the cable of the magnetic latching relay body 5 to pass through, while maintaining good sealing between the cable and the outer shell, achieving waterproof and dustproof functions.

[0025] The rubber ring 15 serves as the outlet for the cable of the magnetic latching relay body 5. After the cable of the magnetic latching relay body 5 passes through the rubber ring 15, the rubber material has good elasticity and compression resilience, which can adapt to cables of different diameters and maintain a tight fit after the cable is threaded through. This achieves waterproof and dustproof protection for the outlet. Furthermore, the cables can be grouped and fixed in the cable tie ring 10 according to different directions or uses, avoiding cable mess or cross-interference and achieving orderly organization and storage.

[0026] Please see Figure 5 The first outer shell 1 has a first magnetic strip 13 embedded on both the front and rear sides, and the second outer shell 2 has a second magnetic strip 14 embedded on both the front and rear sides. When the first outer shell 1 and the second outer shell 2 are closed, the magnetic strips on both sides attract each other due to magnetism, which helps to improve the structural stability and vibration resistance of the shell in the overall closed state and prevents the shell from being opened accidentally due to external force.

Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
