Description

Technical Field

[0001] This utility model relates to the field of electronic device connection structure technology, specifically a magnetic snap-on dual-mode component for a test module used in outdoor environments. Background Technology

[0002] In field environments, testing equipment often needs to be deployed, disassembled, and moved quickly, thus placing high demands on the reliability, convenience, and environmental adaptability of the connection structure. However, existing testing equipment connection methods have the following drawbacks:

[0003] 1. Pure snap-fit ​​structures are prone to wear after frequent disassembly, leading to loose connections;

[0004] 2. Pure magnetic attraction structures are prone to displacement or detachment under vibration.

[0005] 3. Traditional connectors lack dustproof and waterproof designs, making them unsuitable for complex outdoor environments.

[0006] Therefore, we propose a magnetic snap-on dual-mode component for testing modules in field environments. Utility Model Content

[0007] The purpose of this invention is to provide a dual-mode magnetic snap-on component for testing modules in field environments, which solves the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a dual-mode magnetic snap-on assembly for a test module in a field environment, comprising a male head and a female head. A fixing shell is fixed to the end face of the male head, and multiple evenly distributed permanent magnets are fixed in the inner cavity of the fixing shell. Sliding grooves are provided on all four sides of the outer wall of the fixing shell, and elastic latches are installed in two symmetrically arranged sliding grooves. L-shaped guide grooves are provided on both sides of the inner cavity of the female head, and a magnetic conductive sheet is fixed to the end face of the inner cavity of the female head.

[0009] By adopting the above technical solution, when the male and female connectors are plugged in, an adsorption force of ≥2N can be generated when the magnetic attraction distance is 3-5mm, achieving the initial adsorption and positioning of the male and female connectors. After the male and female connectors are connected, the elastic latch can slide in along the L-shaped guide groove and achieve mechanical self-locking after reaching a specific position, further ensuring the stability of the connection.

[0010] In a preferred embodiment of this utility model, an annular elastic sealing ring is installed between the connecting surfaces of the male head and the female seat.

[0011] By adopting the above technical solution, when the male and female connectors are connected, an annular elastic sealing ring is placed on the male connector. During the connection process, the annular elastic sealing ring is compressed and undergoes radial deformation, filling the gap between the male and female connectors and achieving a seal to prevent dust and water from entering.

[0012] In a preferred embodiment of this utility model, push blocks are elastically connected to the two side walls of the female seat at the L-shaped guide groove.

[0013] By adopting the above technical solution, when disassembly is required, pressing the push block can push the elastic latch back, thereby disengaging it from the limit of the L-shaped guide groove, thus facilitating the removal of the male head from the female head.

[0014] In a preferred embodiment of this utility model, a handle is fixedly connected to the end of both the male and female connectors. The handles facilitate the insertion and connection operation of the handheld device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The magnetic module enables initial positioning, while the snap-fit ​​module completes the final locking. Through the synergistic effect of these two different structural modules, a dual guarantee is provided for the connection, significantly improving the reliability of the connection.

[0017] The annular elastic sealing ring can effectively block dust and water after being deformed under pressure, achieving an IP67 protection level, giving the connection system good environmental adaptability and meeting the needs of use in complex outdoor environments.

[0018] The connection system is easy to operate, with a single disassembly and assembly operation time of ≤3 seconds, which greatly improves the efficiency of field operations. Attached Figure Description

[0027] Please see Figure 1-4 This utility model provides a technical solution: a dual-mode magnetic snap-on assembly for a test module in a field environment, including a male head 2 and a female head 1. A fixing shell 21 is fixed to the end face of the male head 2. Multiple evenly distributed permanent magnets 22 are fixed in the inner cavity of the fixing shell 21. Sliding grooves 23 are opened on all four sides of the outer wall of the fixing shell 21. Elastic latches 24 are installed in two symmetrically arranged sliding grooves 23. L-shaped guide grooves 13 are opened on both sides of the inner cavity of the female head 1. A magnetic conductive sheet is fixed to the end face of the inner cavity of the female head 1.

[0028] It should be understood that in actual use, when the male connector 2 and the female connector 1 are plugged in, when the magnetic attraction distance is 3-5mm, an attraction force of ≥2N can be generated to achieve the initial attraction and positioning of the male connector 2 and the female connector 1. After the male connector 2 and the female connector 1 are connected, the elastic latch 24 can slide in along the L-shaped guide groove 13 and achieve mechanical self-locking after reaching a specific position, further ensuring the stability of the connection.

[0029] Furthermore, the inner walls of the female socket 1 are fixed with limiting protrusions 12. When the male head 2 and the female socket 1 are inserted, the limiting protrusions 12 are inserted into the sliding groove 23 to perform limiting insertion, thereby making the insertion and docking accuracy high.

[0030] Furthermore, push blocks 14 are elastically connected to the two side walls of the female seat 1 at the L-shaped guide groove 13. When disassembly is required, pressing the push block 14 can push the elastic latch 24 back, thereby disengaging it from the limit of the L-shaped guide groove 13, thus facilitating the removal of the male head 2 from the female seat 1.

[0031] like Figure 1 and 2 As shown, both the male connector 2 and the female connector 1 are fixedly connected to a handle 11. The handle 11 makes it convenient to use the handheld device for insertion and connection.

[0032] like Figure 1 and 3An annular elastic sealing ring is installed between the connecting surfaces of the male connector 2 and the female connector 1. When the male connector 2 and the female connector 1 are connected, the annular elastic sealing ring is placed on the male connector 2. During the connection process, the annular elastic sealing ring is compressed, resulting in radial deformation, which fills the gap at the connection interface between the male connector 2 and the female connector 1.

[0033] Achieve a seal to prevent dust and water from entering.

[0034] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
