[0002] As electrical connection components in circuit systems, electrical connectors are exposed to long-term vibration and dust pollution in the rail transit field. To ensure the reliability of the equipment, electrical connectors that are less affected by the environment are required.

[0003] For example, Chinese utility model patent with patent number 202222673561.0 provides a high-strength environmentally resistant electrical connector. This electrical connector improves the sealing performance by setting an electrical connector head, plug and gasket. However, traditional electrical connectors mostly use sealing rings for sealing, which are prone to aging and deformation, resulting in a decrease in dustproof performance. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a high-strength, environmentally resistant electrical connector, which solves the technical problem that traditional electrical connectors often use sealing rings for sealing, which are prone to aging and deformation, leading to a decline in dustproof performance.

[0005] The purpose and effect of this utility model of a high-strength environmentally resistant electrical connector are achieved by the following specific technical means:

[0006] A high-strength environmentally resistant electrical connector includes a plug and a connector. The plug has multiple sets of pins on one side, and the connector has multiple sets of slots on one side corresponding to the multiple sets of pins. A sealing component is provided on the outside of the plug and the connector.

[0007] The sealing assembly includes two sets of first protective housings and two sets of second protective housings, the plug is installed between the two sets of first protective housings, and the connector is installed between the two sets of second protective housings;

[0008] One set of the first protective housings and one set of the second protective housings are detachably connected by a connecting component.

[0009] According to a preferred embodiment, the sealing assembly further includes two sets of insulating kits, and each of the two sets of first protective shells and the two sets of second protective shells has a fixing groove on the side adjacent to each other, and the two sets of insulating kits are respectively locked in the two sets of fixing grooves.

[0010] According to a preferred embodiment, two sets of connecting wires are provided on the side of the plug corresponding to the connector, and the two sets of connecting wires on the side of the plug and the connector are respectively passed through the two sets of insulating kits.

[0011] According to a preferred embodiment, fixing holes are provided on both sets of the first protective shell, both sets of the second protective shell, and both sets of the insulating kit, and fixing screws are inserted into the fixing holes.

[0012] According to a preferred embodiment, grooves are correspondingly provided between the two sets of first protective shells and the two sets of second protective shells, and a sealing ring is provided in the groove.

[0013] According to a preferred embodiment, the connecting component includes a locking head and a locking block, wherein a locking head is provided on one side of a first protective shell, and a locking block is provided on one side of a second protective shell, and one end of the locking head is detachably engaged with the locking block.

[0014] According to a preferred embodiment, the second protective shell has a mounting groove on its top, a waterproof button on its top, and a through hole at the bottom of the mounting groove corresponding to the clip head. A slidable ejector rod passes through the through hole, with its top contacting the waterproof button and its bottom contacting the clip head.

[0015] According to a preferred embodiment, a spring ring is provided around the ejector rod, and a spring is provided in the mounting groove. The top end of the spring contacts the spring ring, and the bottom end of the spring contacts the top of the mounting groove.

[0016] Each of the two sets of first protective shells has a guide member on an adjacent side, and each of the two sets of second protective shells has a guide groove on an adjacent side. The two sets of guide members are slidably connected to the two sets of guide grooves.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting two sets of first protective shells and two sets of second protective shells on the outside of the plug and connector, and setting a sealing ring in the groove between adjacent protective shells, and cooperating with the insulating kit that is snapped into the fixing groove, a multi-layer sealing protection system is formed. The sealing ring fills the gap of the groove to prevent the intrusion of external moisture, dust and other substances; the insulating kit is snapped into the fixing groove, which not only isolates the protective shell from the internal conductive parts, but its own structure can also help seal and reduce gaps. This multi-layer sealing structure avoids the sealing failure problem caused by the aging and deformation of a single sealing ring, extends the protection life of the electrical connector, and ensures that it can maintain good dustproof and waterproof performance in harsh environments such as humidity and dust.

[0019] 2. Through the design of the connecting components, the first protective shell and the second protective shell adopt a snap-fit ​​method with a snap-fit ​​head and a snap-fit ​​block. The snap-fit ​​head and the snap-fit ​​block are detachably snap-fitted together. The waterproof button contacts the snap-fit ​​head through the ejector rod. The spring in the mounting slot cooperates with the return ring to form an unlocking mechanism with a spring-loaded function. When it is necessary to maintain or repair the electrical connector, press the waterproof button, and the ejector rod pushes the snap-fit ​​head down to separate it from the snap-fit ​​block. This allows the two sets of first protective shells on the plug and the two sets of second protective shells on the connector to be separated, facilitating the inspection or replacement of the internal pins and slots. After releasing the button, the spring pushes the ejector rod back to its original position through the return ring, and the waterproof button returns to its original position. This provides a convenient disassembly method, solves the problem of difficult maintenance of traditional electrical connectors, and reduces maintenance time and workload.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0029] As attached Figure 1 To be continued Figure 6 As shown:

[0030] This utility model provides a high-strength environmentally resistant electrical connector, including a plug 11 and a connector 12. Multiple sets of pins 13 are provided on one side of the plug 11, and multiple sets of slots 14 are provided on one side of the connector 12 corresponding to the multiple sets of pins 13. Electrical connection is formed when the pins 13 are inserted into the slots 14. A sealing assembly is provided on the outside of the plug 11 and the connector 12. The sealing assembly includes two sets of first protective shells 21 and two sets of second protective shells 22. A first protective groove and a second protective groove are respectively formed on the adjacent sides of the two sets of first protective shells 21 and the two sets of second protective shells 22. The plug 11 is installed in the first protective groove, and the connector 12 is installed in the second protective groove. A detachable connection is achieved between one set of first protective shells 21 and one set of second protective shells 22 through a connecting assembly, providing external protection for the electrical connector and facilitating disassembly and maintenance.

[0031] Please refer to, for example Figure 2 and Figure 5 As shown, the sealing assembly also includes two sets of insulating kits 23. The two sets of first protective shells 21 and the two sets of second protective shells 22 are each provided with a fixing groove 24 on their adjacent sides. The two sets of insulating kits 23 are respectively locked in the two sets of fixing grooves 24. The plug 11 and the connector 12 are each provided with two sets of connecting wires 15 on their corresponding sides. These connecting wires 15 pass through the two sets of insulating kits 23 respectively. The insulating kits 23 are provided to isolate the protective shell from the internal conductive components, so as to avoid the protective shell from direct contact with the connecting wires 15 and other conductive components and short circuit.

[0032] Specifically, the two sets of first protective shells 21 and two sets of second protective shells 22 on the outside of the plug 11 and connector 12 cooperate with each other, together with the insulating kit 23 installed in the fixing groove 24, to form a multi-layer protection. A sealing ring 27 is provided between the protective shells. When the protective shells are connected, the sealing ring 27 is squeezed, which can effectively prevent external moisture, dust and other substances from entering the electrical connector. This multi-layer sealing method is different from the traditional single sealing ring design. Even if one layer of seal ages or is slightly damaged, the sealing structure of other layers can still play a protective role, thereby avoiding the problem of sealing failure caused by aging or deformation of a single sealing ring. This greatly extends the protection life of the electrical connector, enabling it to work reliably in harsh environments such as humidity and dust, and maintain good dustproof and waterproof performance.

[0033] Please refer to, for example Figure 2As shown, each of the two sets of first protective shells 21, the two sets of second protective shells 22, and the two sets of insulating kits 23 has a fixing hole 26. A fixing screw passes through the fixing hole 26 to firmly connect the two sets of first protective shells 21, the two sets of second protective shells 22, and the two sets of insulating kits 23 together. This ensures that the components of the electrical connector will not easily loosen during use, thereby guaranteeing the sealing performance and structural strength of the electrical connector. Corresponding positions of the two sets of first protective shells 21 and the two sets of second protective shells 22 have grooves, in which sealing rings 27 are placed. When the plug 11 and the connector 12 are connected, the two sets of first protective shells 21 and the two sets of second protective shells 22 also align. At this time, the sealing rings 27 in the grooves are compressed, filling the gaps between the protective shells, further enhancing the sealing performance of the electrical connector, effectively preventing external liquids, dust, etc. from entering the interior of the electrical connector, and protecting the internal components such as the pins 13 and the slots 14 from the influence of the external environment.

[0034] Please refer to, for example Figure 2 and Figure 4 As shown, the connecting assembly includes a locking head 31 and a locking block 32. The locking head 31 is provided on one side of a set of first protective shells 21, and the locking block 32 is provided on one side of a set of second protective shells 22. One end of the locking head 31 and the locking block 32 can be detachably locked together. This locking method allows the set of first protective shells 21 and the set of second protective shells 22 to be firmly connected together. At the same time, it is also convenient to disassemble when needed. The two can be separated simply by releasing the locking state of the locking head 31 and the locking block 32, which provides convenience for the maintenance and repair of the electrical connector.

[0035] Please refer to, for example Figure 2 and Figure 3 As shown, the second protective shell 22 has a mounting groove on the top, a waterproof button 34 is provided on the top of the mounting groove, and a through hole is provided at the bottom of the mounting groove corresponding to the clip 31. A push rod 35 is inserted through the through hole and can slide in the through hole. The top of the push rod 35 contacts the waterproof button 34 and the bottom contacts the clip 31. A spring ring 36 is provided around the push rod 35. A spring 37 is also provided in the mounting groove. The top of the spring 37 contacts the spring ring 36 and the bottom contacts the top of the mounting groove.

[0036] Specifically, when maintenance or repair of the electrical connector is required, pressing the waterproof button 34 causes it to move downwards, pushing the ejector rod 35 to slide downwards within the through hole. The bottom end of the ejector rod 35 then pushes the latch 31 downwards, separating the latch 31 from the latch block 32 and releasing their locking state. At this point, the two sets of first protective shells 21 can be separated from the two sets of second protective shells 22 on the connector 12, exposing the internal pins 13 and slots 14 for easy inspection or replacement by staff. After maintenance is completed, releasing the waterproof button 34 causes the spring 37 in the mounting slot to push the ejector rod 35 upwards via the return ring 36, which in turn causes the waterproof button 34 to return to its original position. The protective shells of the electrical connector can be disassembled without the need for complex tools, solving the problem of difficult maintenance of traditional electrical connectors, reducing maintenance time and workload, and improving maintenance efficiency.

[0037] Guide members 38 are provided on the adjacent sides of the two sets of first protective shells 21, and guide grooves 39 are provided on the adjacent sides of the two sets of second protective shells 22. The guide members 38 correspond to the guide grooves 39, and the guide members 38 can slide within the guide grooves 39. This guide structure can guide the two sets of first protective shells 21 and the two sets of second protective shells 22 to accurately align when the plug 11 is connected to the connector 12, ensuring that the locking head 31 can be smoothly inserted into the locking block 32, and avoiding problems such as difficulty in locking or poor sealing due to inaccurate alignment.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
