Description

Technical Field

[0001] The present invention relates to the field of electrical connectors, and more specifically, to a three-way conductive electrical connector. Background Art

[0002] A three-way conductive electrical connector generally refers to a connector that can simultaneously connect three independent circuits. Such connectors are widely used in various electronic devices and systems, such as power distribution, multi-channel signal transmission, etc.

[0003] For a three-way conductive electrical connector, a main wire needs to be inserted into the three-way conductive electrical connector, and the other two cables are inserted into the three-way conductive electrical connector for electrical connection. In real life, when using a three-way conductive electrical connector, especially during the decoration process, since other cables need to be inserted according to the three-way conductive electrical connector later, or the circuit needs to be added to ensure the normal use of electrical appliances, one or two of the branch insertion tubes of the three-way conductive electrical connector need to be kept vacant. In a family with children, in order to prevent children from inserting conductive materials into the insertion tubes of the three-way conductive electrical connector, resulting in the situation of accidental electrical contact inside the three-way conductive electrical connector, it is necessary to add an anti-miscontact function to the three-way conductive electrical connector. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a three-way conductive electrical connector.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A three-way conductive electrical connector includes an electrical connector body. Three groups of insertion tubes are fixedly installed on the electrical connector body. Cables are arranged in the insertion tubes. Each insertion tube is provided with an insertion cavity. A circular chute is opened on the inner wall of the insertion cavity, and the circular chute extends to one end of the insertion tube close to the electrical connector body. A first contact ring is slidably arranged in the circular chute, and a second contact ring is fixedly connected to the inner wall of the circular chute at one end close to the electrical connector body. The cables in the three groups of insertion tubes can be electrically connected to the electrical connector body through the first contact ring and the second contact ring. A plurality of groups of partition plates are arranged in the insertion cavity. Each group of partition plates is in a circular plate shape, and the partition plates are used to block foreign objects from entering the insertion cavity.

[0007] Furthermore, a collar is fixedly sleeved on the outer surface of the insertion tube. A plurality of groups of sliding cavities are equidistantly opened in the circumferential direction in the collar. A thrust spring is arranged in each sliding cavity. One end of the thrust spring is fixedly connected to the inner wall of the sliding cavity. The other end of each group of thrust springs is respectively fixedly connected to each group of partition plates. The sliding cavity can accommodate the partition plate to completely shrink inside. The end of the partition plate for contacting the cable is sharply arranged. The partition plate is made of hard rubber material and its surface is smooth.

[0008] Further, a warning rod is arranged in each of the sliding cavities. One end of the warning rod slidably penetrates through the inner wall of the sliding cavity and extends to the outside of the sliding cavity. The other end of the warning rod is fixedly connected to the partition board, and the thrust spring is sleeved on the outer surface of the warning rod.

[0009] Further, an insulating ring is fixedly connected to the end of the first contact ring away from the second contact ring. A clamping ring is fixedly connected to the end of the insulating ring away from the first contact ring. A plurality of groups of arc grooves are equidistantly arranged on the inner circumference of the clamping ring. A conductive arc block is fixedly arranged in each group of arc grooves. A conductive spring is fixedly connected to the outer surface of each end of the clamping ring away from the insulating ring. The end of the conductive spring away from the insulating ring is fixedly connected to the inner wall of the ring chute.

[0010] Further, an airbag cavity is formed in the inner wall of the intubation tube. An airbag main body is slidably arranged in the airbag cavity. A circular cavity is further formed in the inner wall of the intubation tube. A corrugated pipe is slidably arranged in the circular cavity. One end of the airbag main body is fixedly connected to a first one-way valve. The airbag main body is communicated with the front end of the corrugated pipe through the first one-way valve. A spraying material chute is further formed in the inner wall of the intubation tube. A spraying material box is slidably arranged in the spraying material chute. A telescopic hose is fixedly inserted into one end of the spraying material box close to the corrugated pipe. The spraying material box is communicated with the corrugated pipe through the telescopic hose. A second one-way valve is fixedly inserted into one end of the spraying material box close to the inner wall of the intubation tube. The air outlet end of the second one-way valve penetrates through the partition board. A short board is slidably arranged in the circular cavity. The short board is fixedly connected to the end of the corrugated pipe. The other end of the short board is fixedly connected to the clamping ring.

[0011] Further, the top end of the corrugated pipe is fixedly connected to the inner wall of the circular cavity. The end of the airbag main body connected to the first one-way valve is fixedly connected to the inner wall of the airbag cavity. The telescopic hose consists of two hoses with different thicknesses, and the thinner hose is slidably and sealingly arranged in the thicker hose.

[0012] Further, one end of the circular plate-like structure formed by each group of partition boards is in a funnel shape, and the part of the partition board in the funnel-shaped structure is close to the insulating ring.

[0013] Further, the length of the spraying material chute is the same as the total length of the second one-way valve and the spraying material box, and the second one-way valve is inclined on the side close to the insulating ring, and the inclination degree of the second one-way valve is the same as the inclination degree of the surface of the partition board.

[0014] Further, a peroxide-based resin material is arranged in the spraying material box, and nitrogen is arranged in the airbag main body.

[0015] Further, each group of the conductive springs is electrically connected to each group of conductive arc blocks respectively. Each group of the conductive springs is in a compressed state under the power-off state, and the elastic force of the conductive springs under the power-off state is less than the elastic force when the thrust springs contract. The length of the annular chute is half of the length of the insertion tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) By providing the annular chute, the clamping ring, the first contact ring, the second contact ring and the partition board, the partition board makes the metal object inserted into the insertion tube in the external part contact with the second contact ring. When the size of the object inserted into the insertion tube cannot match the size of the wire insertion cavity, the clamping ring cannot move in the annular chute, so that the first contact ring is not connected to the second contact ring, and there will be no miscontact inside the electrical connector body. The applicable range of the materials inserted into the insertion tube can be reduced, and the occurrence of miscontact can be greatly reduced, thereby improving the safety of the three-way conductive electrical connector in use.

[0018] (2) By providing the warning rod and the partition board, when the warning rods all extend out of the collar, it indicates that the cable has been inserted into the insertion tube. By combining with the phenomenon of whether the cable is powered on, it can be judged whether the device has inserted the cable properly. It can be judged by whether the warning rods extend out of the outside of the collar whether there is a leakage of the cable inserted into the insertion tube, ensuring the safety of the electrical connector body during use, and being able to timely remind the user whether there is a leakage inside the electrical connector body, further reducing the occurrence of greater economic and safety losses.

[0019] (3) By providing the airbag body, the corrugated pipe, the spraying box, the first one-way valve and the second one-way valve, the peroxide-based resin material will fill the part of the wire insertion cavity with the annular chute, thereby wrapping the leaking part of the cable, reducing the problems caused by the leakage of the cable. Since the peroxide-based resin material will change from a foam state to a solid state after contacting oxygen, when the cable is pulled out of the insertion tube, the solid peroxide-based resin material will wrap the cable, avoiding the occurrence of electric shock, and further ensuring the safety of the disassembly when the cable leaks inside the electrical connector body.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 7 , a three-way conductive electric connector, including an electric connector body 1, three groups of cannulas 2 are fixedly installed on the electric connector body 1, cables are arranged in the cannulas 2, a wire insertion cavity 3 is opened in each group of cannulas 2, a ring chute 4 is opened on the inner wall of the wire insertion cavity 3, the ring chute 4 extends to one end of the cannula 2 close to the electric connector body 1, a first contact ring 5 is slidably arranged in the ring chute 4, a second contact ring 6 is fixedly connected to the inner wall of the ring chute 4 close to the electric connector body 1, the cables in the three groups of cannulas 2 can be electrically connected to the electric connector body 1 through the first contact ring 5 and the second contact ring 6, multiple groups of partition boards 7 are arranged in the wire insertion cavity 3, each group of partition boards 7 is in a circular plate shape, and the partition boards 7 are used to block foreign objects from entering the wire insertion cavity 3.

[0031] When using an electrical connector, first insert the cable into the insertion tube 2 of the electrical connector body 1. At this time, the power connection head of the cable will be electrically connected to the electrical connector body 1 through the conductive action of the first contact ring 5 and the second contact ring 6. The cables electrically connected through the electrical connector will be connected to achieve the power transmission function. During actual use, when other metal objects are inserted into the insertion tube 2, first, due to the presence of the partition plate 7, the external metal objects cannot separate the partition plate 7, so the metal objects inserted into the insertion tube 2 from the outside are in contact with the second contact ring 6 through the partition plate 7. Second, if the size of the object inserted into the insertion tube 2 cannot match the size of the wire insertion cavity 3, the clamping ring 13 cannot move in the ring chute 4, so that the first contact ring 5 and the second contact ring 6 are not connected, and there will be no accidental contact inside the electrical connector body 1. The material inserted into the insertion tube 2 needs to meet the conditions of being able to match the size of the wire insertion cavity 3 and being able to separate the partition plate 7, which can narrow the applicable range of the material inserted into the insertion tube 2 and greatly reduce the occurrence of accidental contact, thereby improving the safety of the three-way conductive electrical connector.

[0032] As Figure 2 and Figure 5 shown, a collar 8 is fixedly sleeved on the outer surface of the insertion tube 2. A plurality of groups of sliding cavities 9 are equidistantly arranged in a circle in the collar 8. A thrust spring 10 is arranged in the sliding cavity 9. One end of the thrust spring 10 is fixedly connected to the inner wall of the sliding cavity 9, and the other end of each group of thrust springs 10 is respectively fixedly connected to each group of partition plates 7. The sliding cavity 9 can accommodate the partition plate 7 to completely retract inside. The end of the partition plate 7 for contacting the cable is sharp. The partition plate 7 is made of hard rubber and its surface is smooth.

[0033] One end of the disc-shaped structure formed by each group of partition plates 7 is funnel-shaped, and the funnel-shaped part of the partition plate 7 is close to the insulating ring 12.

[0034] When the cable is inserted into the wire insertion cavity 3 of the insertion tube 2, the cable will contact the clamping ring 13. Due to the funnel-shaped design of the clamping ring 13, it will squeeze the cable. Then, through the friction force between the cable and the clamping ring 13, the cable will drive the clamping ring 13 to move from left to right in the wire insertion cavity 3 as Figure 2 shown, so that the first contact ring 5 fixedly connected to the clamping ring 13 contacts the partition plate 7. Due to the funnel-shaped design on the surface of the partition plate 7, the first contact ring 5 contacts a plurality of groups of partition plates 7, causing the plurality of groups of partition plates 7 to move away from each other, and then the wire insertion cavities 3 on both sides of the partition plate 7 are connected. At this time, the cable can continue to move to the right side of the wire insertion cavity 3 until the first contact ring 5 contacts the second contact ring 6 to complete the installation of the cable. At this time, only need to judge whether the cable on the electrical connector body 1 is powered on to know whether the cable is inserted properly, avoiding the situation that the cable is not fully inserted into the wire insertion cavity 3, the insertion is unstable, and the cable inside the electrical connector body 1 often loses power due to not being inserted tightly.

[0035] Moreover, since one end of the partition plate 7 for contacting the cable is sharply set, and the partition plate 7 is made of hard rubber and has a smooth surface treatment, it can effectively fix the cable inserted into the wire insertion cavity 3, and at the same time, it can reduce the damage to the cable caused by the excessive elastic force of the thrust spring 10 through the partition plate 7, ensuring the safety of the electrical connector body 1 during use;

[0036] It should be particularly noted here that the clamping ring 13 is in a funnel shape, and the thickness of the clamping ring 13 gradually increases from the outer end to the inner end of the insertion tube 2, and the inner diameter at the position where the clamping ring 13 has the largest thickness is smaller than the inner diameter of the wire insertion cavity 3.

[0037] As Figure 3 and Figure 4 shown, a warning rod 11 is arranged in each sliding cavity 9. One end of the warning rod 11 slides through the inner wall of the sliding cavity 9 and extends to the outside of the sliding cavity 9. The other end of the warning rod 11 is fixedly connected to the partition plate 7, and the thrust spring 10 is sleeved on the outer surface of the warning rod 11.

[0038] When the cable is inserted into the wire insertion cavity 3, due to the extrusion of the cable, multiple partition plates 7 will move away from each other and respectively enter multiple sliding cavities 9, so that the wire insertion cavities 3 on both sides of the partition plate 7 are communicated. When the partition plate 7 enters the sliding cavity 9, the partition plate 7 will simultaneously move the warning rod 11 together and extend from the outer surface of the collar 8. At this time, the thrust spring 10 contracts. When all the warning rods 11 extend out of the collar 8, it indicates that the cable has been inserted into the insertion tube 2. By combining with the phenomenon of whether the cable is energized, it can be judged whether the device has inserted the cable properly. When the electrical connector body 1 leaks electricity, under the action of the thrust spring 10, multiple partition plates 7 will move closer to each other, and then the warning rod 11 will move back into the sliding cavity 9 again. It can be judged by whether the warning rod 11 extends out of the outside of the collar 8 whether there is a situation of cable leakage in the insertion tube 2, ensuring the safety of the electrical connector body 1 during use, and being able to timely remind the user whether there is electricity leakage inside the electrical connector body 1, further reducing the occurrence of greater economic and safety losses.

[0039] As Figure 2 and Figure 5 shown, an insulating ring 12 is fixedly connected to one end of the first contact ring 5 away from the second contact ring 6. An insulating ring 12 is fixedly connected to one end of the insulating ring 12 away from the first contact ring 5. A plurality of arc grooves 14 are equidistantly arranged on the inner circumference of the clamping ring 13. A conductive arc block 15 is fixedly arranged in each arc groove 14. A conductive spring 16 is fixedly connected to the outer surface of each clamping ring 13 away from the insulating ring 12. One end of the conductive spring 16 away from the insulating ring 12 is fixedly connected to the inner wall of the ring chute 4.

[0040] When the cable inside the cable insertion cavity 3 leaks electricity, the leaking cable will cause the conductive arc block 15 to be electrified, thus enabling the conductive spring 16 to work. At this time, the conductive spring 16 contracts, driving the clamping ring 13, the insulating ring 12, and the first contact ring 5 to move leftward as shown in Figure 2 shown in, so that the first contact ring 5 separates from the second contact ring 6, and then disconnects the cable from the electrical connector body 1, achieving the function of power-off, avoiding continuous power supply when the cable leaks electricity and causing greater damage, and further ensuring the safe use of the electrical connector body 1;

[0041] It should be particularly noted here that when current passes through the spring, the spring will transform into an electromagnet, and the current generates a magnetic field. The relationship between the current direction and the magnetic field direction follows Ampere's law, that is, the current and the magnetic field are perpendicular to each other, and adjacent segments of the spring will approach each other. The stronger the magnetic field, the greater the degree of spring contraction.

[0042] As shown in Figures 2 to 7 , an airbag cavity 17 is formed in the inner wall of the insertion tube 2, an airbag main body 18 is slidably arranged in the airbag cavity 17, a circular cavity 19 is also formed in the inner wall of the insertion tube 2, a corrugated pipe 20 is slidably arranged in the circular cavity 19, one end of the airbag main body 18 is fixedly connected to a first one-way valve 21, and the airbag main body 18 communicates with the front end of the corrugated pipe 20 through the first one-way valve 21. A material spraying chute 22 is also formed in the inner wall of the insertion tube 2, a material spraying box 23 is slidably arranged in the material spraying chute 22, a telescopic hose 24 is fixedly inserted at one end of the material spraying box 23 close to the corrugated pipe 20, and the material spraying box 23 communicates with the corrugated pipe 20 through the telescopic hose 24. A second one-way valve 25 is fixedly inserted at one end of the material spraying box 23 close to the inner wall of the insertion tube 2, and the air outlet end of the second one-way valve 25 penetrates through the partition plate 7. A short plate 26 is slidably arranged in the circular cavity 19, the short plate 26 is fixedly connected to the end of the corrugated pipe 20, and the other end of the short plate 26 is fixedly connected to the clamping ring 13.

[0043] The top end of the corrugated pipe 20 is fixedly connected to the inner wall of the circular cavity 19, and one end of the airbag main body 18 connected to the first one-way valve 21 is fixedly connected to the inner wall of the airbag cavity 17. The telescopic hose 24 consists of two hoses with different thicknesses, and the thinner hose is slidably and sealingly arranged in the thicker hose.

[0044] The length of the material spraying chute 22 is the same as the total length of the second one-way valve 25 and the material spraying box 23, and the side of the second one-way valve 25 close to the insulating ring 12 is inclined, and the inclination degree of the second one-way valve 25 is the same as the inclination degree of the surface of the partition plate 7.

[0045] The material spraying box 23 is provided with a peroxide-based resin material, and the airbag main body 18 is provided with nitrogen.

[0046] When the cable is inserted into the cable insertion cavity 3 and the cable contacts the clamping ring 13, since the entire clamping ring 13, insulating ring 12, and first contact ring 5 move together as shown inFigure 7 When moving rightward in the annular chute 4 as shown, the clamping ring 13 will elongate the bellows 20 through the short plate 26. Meanwhile, the bellows 20 will suck out the nitrogen in the airbag body 18 through the first one-way valve 21, causing the nitrogen to rush into the interior of the bellows 20. When the cable leaks electricity, under the action of the conductive spring 16, the entire clamping ring 13, insulating ring 12, and first contact ring 5 will move together as Figure 7 When moving leftward in the annular chute 4 as shown, the clamping ring 13 will cause the bellows 20 to contract through the short plate 26. Due to the action of the first one-way valve 21, the nitrogen in the bellows 20 will rush into the spray material tank 23, and then the peroxide-based resin material in the spray material tank 23 will be extruded through the second one-way valve 25. The peroxide-based resin material will fill the part of the wire insertion cavity 3 with the annular chute 4, thus wrapping the part of the cable with leakage, reducing the problems caused by cable leakage. Since the peroxide-based resin material will change from a foam state to a solid state after contacting oxygen, when the cable is pulled out from the insertion tube 2, the solid peroxide-based resin material will wrap the cable, avoiding the occurrence of electric shock, and further ensuring the safety of disassembly when the cable in the electrical connector body 1 leaks electricity;

[0047] It should be particularly noted here that: the first one-way valve 21 is used to introduce the nitrogen in the airbag body 18 into the bellows 20, and the second one-way valve 25 is used to eject the peroxide-based resin material inside the spray material tank 23;

[0048] The peroxide-based resin material is in a foam state after production, will gradually change to a solid state after contacting oxygen in the air, and has an insulating effect.

[0049] As Figure 2 and Figure 5 shown, each group of conductive springs 16 is electrically connected to each group of conductive arc blocks 15 respectively. Each group of conductive springs 16 is in a compressed state under the power-off state, and the elastic force of the conductive spring 16 under the power-off state is less than the elastic force when the thrust spring 10 contracts. The length of the annular chute 4 is half of the length of the insertion tube 2.

[0050] Due to cable leakage, under the action of the conductive spring 16, the entire insulating ring 12, clamping ring 13, and first contact ring 5 will move leftward simultaneously as Figure 2 shown, until moving to the left side of the partition plate 7. Meanwhile, under the action of the thrust spring 10, multiple groups of partition plates 7 will approach each other until the wire insertion cavity 3 at the right end of the cable is closed, making the entire leaking cable located in the wire insertion cavity 3. When disassembling, touching the insertion tube 2 by hand can avoid electric shock, which can avoid safety problems for the disassembling personnel due to cable leakage during disassembly, and the cable is located inside the insertion tube 2, avoiding the problem that the leaking cable on the ground is accidentally touched, and further ensuring the safety of the electrical connector body 1 during use.

[0051] Usage method: When using the electrical connector, first insert the cable into the insertion tube 2 of the electrical connector body 1. At this time, the power connection head of the cable will be electrically connected to the electrical connector body 1 through the conductive action of the first contact ring 5 and the second contact ring 6. The cables electrically connected through the electrical connector will be connected to achieve the power transmission function. During actual use, when other metal objects are inserted into the insertion tube 2, first, due to the presence of the partition plate 7, the external metal object cannot separate the partition plate 7, so the external metal object inserted into the insertion tube 2 is in contact with the second contact ring 6 through the partition plate 7. Secondly, if the size of the object inserted into the insertion tube 2 does not match the size of the wire insertion cavity 3, the clamping ring 13 cannot move in the ring chute 4, so that the first contact ring 5 and the second contact ring 6 are not connected, and there will be no accidental contact inside the electrical connector body 1. The material inserted into the insertion tube 2 needs to meet the conditions of being able to match the size of the wire insertion cavity 3 and being able to separate the partition plate 7, which can narrow the applicable range of the material inserted into the insertion tube 2 and greatly reduce the occurrence of accidental contact, thereby improving the safety of using the three-way conductive electrical connector.

[0052] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
