Description

Technical Field

[0001] The present invention belongs to the technical field of anti-misconnection wire connection joints, and specifically relates to a safety shielding protection device for an anti-misconnection electrical connection coupling system. Background Art

[0002] In the power transmission and transformation system, especially in the field of State Grid equipment, the misinsertion of connectors may lead to situations such as equipment short circuit, phase sequence disorder, overload, or signal interference.

[0003] For the single mechanical anti-misconnection structure in the prior art, an asymmetric plug shape or a guiding keyway design is usually adopted. However, after long-term plugging and unplugging, structural wear is likely to occur, resulting in an increase in the anti-misconnection failure rate; or visual markings are used for assistance, such as color coding and text identification. However, when the color coding and text identification are worn or soiled and cannot be distinguished, misinsertion will also occur.

[0004] Therefore, a safety shielding protection device for an anti-misconnection electrical connection coupling system is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an anti-misconnection electrical connection coupling system safety shielding protection device that can overcome or at least partially solve the above problems.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: an anti-misconnection electrical connection coupling system safety shielding protection device, including a first connector and a second connector connected to each other, and further including: a first magnetic ring sleeved on a sleeve member of the first connector; a second magnetic ring sleeved on a plug of the second connector, and the first magnetic ring and the second magnetic ring repel each other with the same poles and attract each other with opposite poles to achieve primary anti-misconnection verification; a threaded sleeve for locking the second connector on the first connector; a secondary anti-misconnection mechanism respectively located on the first connector and the second connector for performing secondary anti-misconnection verification when the plug is inserted into the sleeve member.

[0007] Preferably, a first spring is connected to the sleeve member, one end of the first spring is fixedly connected with a first mounting ring, the first magnetic ring is fixedly connected to the first mounting ring, guide grooves are symmetrically opened on the sleeve member, and the first mounting ring is slidably connected in the guide grooves.

[0008] Preferably, a slip ring is slidably connected to the plug of the second connector. A second spring is sleeved on the plug. One end of the second spring is fixedly connected to a second mounting ring. The other end of the second spring is fixedly connected to the slip ring. The second magnetic ring is fixedly connected to the second mounting ring. Guide grooves are symmetrically formed in the plug. The slip ring slides on the guide grooves. The threaded sleeve is located between the slip ring and the wide-diameter block two. Clamping pieces are symmetrically arranged on the inner diameter of the second mounting ring. The clamping pieces are in contact with the outer circumference of the plug.

[0009] Preferably, mounting grooves are symmetrically formed in the sleeve member. Elastic pieces are mounted in the mounting grooves. An arc-shaped block and a mounting block are respectively connected to the front end of the sleeve member close to the sleeve member. The arc-shaped block is located inside the diameter of the sleeve member.

[0010] Preferably, the secondary anti-misinsertion mechanism includes an anti-misinsertion groove formed in the mounting block and a slot formed in the second mounting ring. The slot corresponds to the mounting block. An anti-misinsertion block is arranged on the slot.

[0011] Furthermore, a fixing ring is fixedly connected to the wide-diameter block one. A guide rod is slidably connected to the fixing ring. A guide sleeve is fixedly connected to the fixing ring. One end of the guide rod slides in the guide sleeve. A third spring is connected between the guide rod and the guide sleeve. A connecting pipe and an inflation pipe are respectively connected to the guide sleeve. The inflation pipe leads to the sleeve member. A through hole is formed in the guide rod.

[0012] Furthermore, a hook is fixedly connected to the side of the second mounting ring away from the second magnetic ring. A card slot is formed in the mounting block. The hook corresponds to the card slot.

[0013] Furthermore, a first protective sleeve is fixedly connected between the first mounting ring and the wide-diameter block one. A cavity is formed between the first protective sleeve and the sleeve member. The inflation pipe leads to the cavity.

[0014] Furthermore, a second protective sleeve is connected between the wide-diameter block two and the threaded sleeve.

[0015] Furthermore, an annular indicator light is fixedly connected to the first connector. A second contact is fixedly connected to the end of the guide rod. A first contact is arranged on the annular indicator light.

[0016] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. The safety shielding protection device of the anti-misconnection electrical connection coupling system can realize the first-level anti-misconnection verification before the first connector and the second connector are physically in contact through the same-pole repulsion characteristics of the first and second magnetic rings. If the polarity does not match, the first connector and the second connector will automatically repel each other to avoid the risk of misconnection. This link solves the problems of hysteresis of power-on detection after insertion of traditional connectors, inability to identify due to wear and tear of plugging and unplugging, and misconnection caused by wear and dirt of visual markings, which significantly improves the screening efficiency;

[0018] 2. The safety shielding protection device of the error-proof electrical connection coupling system, when the magnetic ring 1 and the magnetic ring 2 are adsorbed and pass the first-level error-proofing verification, when the plug is inserted into the sleeve, the spring piece and the arc block form a preliminary clamping on the plug, and at the same time the spring piece closes the installation groove, actively isolating external foreign matter and liquid, forming a front safety barrier;

[0019] 3. The safety shielding protection device of the anti-error electrical connection coupling system, during the tightening process of the threaded sleeve, the matching of the anti-error groove and the anti-error block constitutes a secondary anti-error insertion verification. If the anti-error groove and the anti-error block are misaligned, the second compression resistance of the spring increases sharply, and the threaded sleeve cannot be completely tightened, forming a tactile feedback alarm. When the anti-error groove and the anti-error block are matched, the hook and the card slot bite, triggering the spring to tilt, providing conditions for the activation of the safety shielding protection system formed by the subsequent nitrogen filling;

[0020] 4. The safety shielding protection device of the anti-error electrical connection coupling system, when the primary and secondary anti-error verifications are passed, the tightening of the threaded sleeve pushes the guide rod to trigger the gas path connection, and nitrogen is filled into the cavity through the inflation pipe to form a positive pressure anti-seepage shielding barrier to prevent external liquid from invading. At the same time, when the secondary anti-error verification is passed, the installation slot is opened to allow nitrogen to enter the sleeve to provide anti-oxidation protection for the conductive pins and sockets;

[0021] 5. The safety shielding protection device of the anti-error electrical connection coupling system triggers the lighting of the ring indicator light through the displacement of the guide rod, forming a visual completion signal, so that the operator can instantly perceive the connection status when using it;

[0022] In summary, the magnetic pole verification uses the repulsion characteristics of the same poles of the first and second magnetic rings to quickly screen the polarity matching before the first connector and the second connector come into contact, avoiding the risk of mis-insertion; the secondary error-proofing mechanism triggers a tactile alarm when the threaded sleeve is tightened through the mechanical matching of the error-proofing groove and the error-proofing block and the resistance feedback of the second spring, and builds a safety shielding protection barrier by filling nitrogen during installation, and lights up the ring warning light through the displacement of the guide rod, realizing real-time visualization of the connection completion;

[0023] Each link forms a progressive technical closed loop: the preliminary verification provides the necessary conditions for subsequent operations, and the post-protection reversely enhances the reliability of the device, ultimately achieving an anti-misinsertion effect.

Specific implementation manners

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0042] The following combines the attached Figure 1 - attached Figure 14 , and details the technical solutions provided by each embodiment of the present invention.

[0043] Embodiment 1: Refer to Figures 1 - 14 , an anti-error electrical connection coupling system safety shielding protection device, including a connected first connector 1 and second connector 2, further including: a first magnetic ring 1222 sleeved on the sleeve part 12 of the first connector 1; a second magnetic ring 225 sleeved on the plug 22 of the second connector 2, and the first magnetic ring 1222 and the second magnetic ring 225 repel each other with the same pole and attract each other with different poles to achieve primary anti-misinsertion verification; a threaded sleeve 23 for locking the second connector 2 on the first connector 1; a secondary anti-misinsertion mechanism respectively located on the first connector 1 and the second connector 2 for performing secondary anti-misinsertion verification when the plug 22 is inserted into the sleeve part 12;

[0044] The sleeve member 12 is connected with a spring 122, one end of the spring 122 is fixedly connected with a mounting ring 1221, the magnetic ring 1222 is fixedly connected to the mounting ring 1221, the sleeve member 12 is symmetrically provided with a guide groove 121, and the mounting ring 1221 is slidably connected in the guide groove 121;

[0045] A slip ring 221 is slidably connected to the plug 22 of the second connector 2, a spring 223 is sleeved on the plug 22, a mounting ring 224 is fixedly connected to one end of the spring 223, the other end of the spring 223 is fixedly connected to the slip ring 221, a magnetic ring 225 is fixedly connected to the mounting ring 224, a guide groove 222 is symmetrically provided on the plug 22, the slip ring 221 slides on the guide groove 222, the threaded sleeve 23 is located between the slip ring 221 and the wide diameter block 21, a clamping piece 226 is symmetrically provided on the inner diameter of the mounting ring 224, the clamping piece 226 is in contact with the outer periphery of the plug 22, so as to prevent the mounting ring 224 from being suspended on the plug 22, and then when the magnetic ring 225 is attracted to the magnetic ring 1 1222, the mounting ring 224 is further prevented from being dislocated and skewed, and the clamping piece 226 will bend after being subjected to force;

[0046] When the device is in use, the second magnetic ring 225 on the second connector 2 is placed opposite to the first magnetic ring 1222 on the first connector 1. If a rejection reaction occurs, it means that the second connector 2 is not compatible with the first connector 1. Then, the second connector 2 is replaced to be opposite to another first connector 1.

[0047] It should be understood that in this embodiment, the first-level anti-misinsertion verification is performed by utilizing the characteristics of the first magnetic ring 1222 and the second magnetic ring 225 that the same poles repel each other and the opposite poles attract each other, which is applicable to the case where there are two first connectors 1 and two second connectors 2.

[0048] When the second magnetic ring 225 is attracted to the first magnetic ring 1222, the plug 22 on the second connector 2 is inserted into the sleeve 12 of the first connector 1, so that the socket 220 on the plug 22 enters the conductive pin 123 in the sleeve 12. During the insertion of the plug 22, the first magnetic ring 1222 and the second magnetic ring 225 are pressed against each other, so that the first spring 122 and the second spring 223 are compressed.

[0049] Then, the threaded sleeve 23 is screwed onto the external thread 111 of the wide diameter block 11. During the screwing process, the threaded sleeve 23 gradually approaches the first connector 1, and the threaded sleeve 23 pushes the slip ring 221 to slide in the guide groove 222 and squeezes the spring 223. At this time, the spring 223 pushes the mounting ring 224 and the magnetic ring 225 and sleeves them on the sleeve 12. The secondary anti-mis-insertion verification is performed through the secondary anti-mis-insertion mechanism to further verify whether the first connector 1 matches the second connector 2.

[0050] Therefore, the device can perform quick primary anti-misinsertion verification through the first magnetic ring 1222 and the second magnetic ring 225. When the first magnetic ring 1222 and the second magnetic ring 225 approach each other and repel, it means that the first connector 1 and the second connector 2 do not match. When the first magnetic ring 1222 and the second magnetic ring 225 attract each other after approaching, the next step can be carried out. The plug 22 is inserted into the sleeve member 12. Then, when the first connector 1 and the second connector 2 are tightened through the threaded sleeve 23, anti-misinsertion verification is carried out again through the secondary anti-misinsertion mechanism, thereby effectively preventing misinsertion.

[0051] Embodiment 2: Refer to Figure 6 , Figure 11 , Figure 12 , an anti-misconnection electrical connection coupling system safety shielding protection device, which is basically the same as Embodiment 1. Further, installation grooves 124 are symmetrically formed on the sleeve member 12, and elastic pieces 125 are installed in the installation grooves 124. Arc-shaped blocks 1251 and installation blocks 1252 are respectively connected to the front end of the elastic piece 125 close to the sleeve member 12. The arc-shaped block 1251 is located inside the diameter of the sleeve member 12;

[0052] One end of the elastic piece 125 is fixedly connected to the inner wall of the installation groove 124 away from the opening end of the sleeve member 12. The elastic piece 125, the arc-shaped block 1251, and the installation block 1252 block the installation groove 124 in the initial state. When the plug 22 is inserted into the sleeve member 12, since the arc-shaped block 1251 extends into the sleeve member 12, the arc-shaped block 1251 and the elastic piece 125 can initially clamp the plug 22, avoiding the plug 22 from shaking in the sleeve member 12;

[0053] In addition, in the initial state, the elastic piece 125, the arc-shaped block 1251, and the installation block 1252 block the installation groove 124, which can prevent external foreign objects, dust, and liquid from entering the sleeve member 12 from the installation groove 124 when the first connector 1 and the second connector 2 are separated, thereby achieving the effect of safety shielding protection for the first connector 1.

[0054] Embodiment 3: Refer to Figure 6 , Figure 11 , Figure 13 , Figure 14 , an anti-misconnection electrical connection coupling system safety shielding protection device, which is basically the same as Embodiment 2. Further, the secondary anti-misinsertion mechanism includes an anti-misinsertion groove 1253 formed on the installation block 1252 and a slot 228 formed on the second installation ring 224. The slot 228 corresponds to the installation block 1252, and an anti-misinsertion block 229 is arranged on the slot 228;

[0055] When the anti-misalignment block 229 is aligned with the anti-misalignment groove 1253, the second mounting ring 224 can be smoothly sleeved on the sleeve member 12. When the anti-misalignment block 229 is misaligned with the anti-misalignment groove 1253, during the rotation of the threaded sleeve 23, the threaded sleeve 23 continuously presses the second spring 223, resulting in an increased rotational damping of the threaded sleeve 23. When the second spring 223 is compressed to the limit, the threaded sleeve 23 can no longer continue to rotate the thread on the first wide-diameter block 11, and the open end of the threaded sleeve 23 cannot approach the fixing ring 112 located on the first wide-diameter block 11. At this time, it represents that there is a problem with the matching of the first connector 1 and the second connector 2, and inspection and verification are required.

[0056] Embodiment 4: Refer to Figure 4 , Figure 5 , Figure 7 , Figure 11 , Figure 12 , an anti-misalignment electrical connection coupling system safety shielding and protection device, which is basically the same as Embodiment 3. Further: A fixing ring 112 is fixedly connected to the first wide-diameter block 11. A guide rod 3 is slidably connected to the fixing ring 112. A guide sleeve 31 is fixedly connected to the fixing ring 112. One end of the guide rod 3 slides in the guide sleeve 31. A third spring 32 is connected between the guide rod 3 and the guide sleeve 31. A connecting pipe 34 and an inflation pipe 35 are respectively connected to the guide sleeve 31. The inflation pipe 35 leads to the sleeve member 12. A through hole 33 is provided on the guide rod 3; A first protective sleeve 13 is fixedly connected between the first mounting ring 1221 and the first wide-diameter block 11. A cavity 131 is formed between the first protective sleeve 13 and the sleeve member 12. The inflation pipe 35 leads to the cavity 131;

[0057] When the first-level and second-level anti-misinsertion verifications are passed and the threaded sleeve 23 can be smoothly and successfully tightened on the first connector 1, the end face of the open end of the threaded sleeve 23 will abut against the guide rod 3, causing the guide rod 3 to slide into the guide sleeve 31 on the fixing ring 112, so that the through hole 33 coincides with the connecting pipe 34 and the inflation pipe 35. The connecting pipe 34 connected to the external gas cylinder intakes gas into the inflation pipe 35 through the through hole 33 and discharges it between the first connector 1 and the second connector 2, that is, into the cavity 131;

[0058] The gas is preferably nitrogen. Filling nitrogen between the first connector 1 and the second connector 2 can improve the safety shielding and protection effect and increase the internal pressure to prevent external liquid from entering.

[0059] It should be noted that a one-way valve is provided on the inflation pipe 35. When the gas cylinder connected to the connecting pipe 34 is removed, the nitrogen filled between the first connector 1 and the second connector 2 will not leak out through the inflation pipe 35;

[0060] In one embodiment, the gas cylinder may not be removed. Furthermore, when the gas pressure in the cavity 131 decreases, it can be automatically replenished.

[0061] On one side of the mounting ring two 224 far from the magnetic ring two 225, a hook 2241 is fixedly connected. A clamping groove 1254 is formed on the mounting block 1252, and the hook 2241 corresponds to the clamping groove 1254;

[0062] After the secondary anti-misinsertion mechanism passes the verification, the mounting ring two 224 will cross over the mounting block 1252, and then one end of the hook 2241 is inserted into the clamping groove 1254. As the threaded sleeve 23 is screwed onto the wide-diameter block one 11, the threaded sleeve 23 continuously squeezes the spring two 223, and the mounting ring two 224 and the magnetic ring two 225 continuously move towards the sleeve part 12. Furthermore, the elastic piece 125 is pulled by the hook 2241, so that the elastic piece 125 at one end of the mounting block 1252 warps towards the outer circumference of the sleeve part 12, and thus the arc-shaped block 1251 no longer blocks the mounting groove 124. At this time, the inside of the sleeve part 12 will be connected to the cavity 131, and nitrogen is then filled into the sleeve part 12 to avoid the oxidation problem of the conductive pin 123 and the jack 220.

[0063] A protective sleeve two 227 is connected between the wide-diameter block two 21 and the threaded sleeve 23 to further seal the connection between the first connector 1 and the second connector 2 and prevent the filled nitrogen from leaking.

[0064] Example 5: Refer to Figure 7 、 Figure 12 A safety shielding and protection device for an anti-misconnection electrical connection coupling system, which is basically the same as Example 4. Further: A ring-shaped indicator light 4 is fixedly connected to the first connector 1, and a contact two 42 is fixedly connected to the end of the guide rod 3. A contact one 41 is arranged on the ring-shaped indicator light 4;

[0065] When the guide rod 3 slides in the guide sleeve 31 so that the through hole 33 is opposite to the connecting pipe 34 and the gas filling pipe 35, the contact two 42 on the guide rod 3 contacts the contact one 41, making the ring-shaped indicator light 4 emit light to indicate that the connection between the first connector 1 and the second connector 2 is completely completed;

[0066] A button battery or a rechargeable lithium battery is arranged on the lamp holder of the ring-shaped indicator light 4, and the ring-shaped indicator light 4 uses LED lamp beads, which is more power-saving;

[0067] Furthermore, it can be set to turn off after a certain set time after the ring-shaped indicator light 4 emits light.

[0068] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content prompted above within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention's solution.
