Description

Technical Field

[0001] The present invention relates to the field of cables, and in particular to a safety cable connector with an anti-drop function. Background Art

[0002] With existing plugs, when the male and female plugs are connected, both are exposed to the external environment, which poses certain risks. For example, when using electrical equipment outdoors, long-distance wiring is generally required, and plug adapters are often used in the middle. There is a risk of the line being kicked and stepped on. In this case, the cable itself can be protected by a cable protection groove, but the male and female plugs are much larger than the cable and cannot be protected by the cable protection groove. Therefore, the circuit is easily broken by being kicked and stepped on, affecting the normal use of various electrical equipment; loosening of the adapter due to being kicked and stepped on may lead to poor contact, and then abnormal heating or even spontaneous combustion may occur. The existing technology lacks automatic protection measures for the above problems. In many cases, it can only be dealt with after discovery, and there is a lack of early prevention methods. Summary of the Invention

[0003] In order to overcome the shortcomings of existing male and female connectors that are much larger than cables and cannot be protected by cable protection grooves, so the circuit is easily broken by being kicked or stepped on, affecting the normal use of various power equipment, the present invention provides a safety cable connector with an anti-detachment function.

[0004] The technical implementation scheme of the present invention is: a safety cable connector with an anti-slip function, comprising a female head, a connecting sleeve and a male head; the surface of the female head is connected to the connecting sleeve; the connecting sleeve is slidably connected to the male head, and a number of guide strips are fixedly connected to the surface of the male head; a groove corresponding to the guide strip is opened on the inner side of the connecting sleeve, and the deepest part of the groove and the end of the guide strip are provided with magnetic suction parts that can cooperate with each other; it also includes a thermal conductive ring, a hollow tube, a round rod, an expansion ring, a connecting disk, a connecting ring, a connecting head and a threaded ring; the contact post of the female head is fixed with a thermal conductive ring; the thermal conductive ring is fixed with a number of hollow tubes; each hollow tube is slidably connected to a round rod; an expansion ring is provided in each hollow tube, and the expansion ring is located between the thermal conductive ring and the round rod; the male head is slidably connected to the connecting disk; the connecting disk is fixed with a number of connecting rings, and the number and position of the connecting rings correspond to the slots of the contact post; the male head is detachably connected to the threaded ring; the threaded ring is rotatably connected to the connecting head; the connecting head is used to pass through the cable body.

[0005] Optionally, each connecting ring is fixedly connected to a plurality of convex rings.

[0006] Optionally, the female connector, the connecting sleeve and the male connector are all made of heat-insulating materials.

[0007] Optionally, a sealing ring is provided on the inner side of the connecting sleeve.

[0008] Optionally, the outer ring surface of the threaded ring is provided with a rough texture.

[0009] Optionally, a chuck and a screw are also included; the male head is slidingly connected to a chuck, the chuck has several through holes for fixing the cable body, and the chuck is located on the side of the connecting disk away from the contact column; the chuck is rotatably connected to a screw, and the screw and the connecting disk form a threaded screw to fix it.

[0010] Optionally, a pressure rod is also included; each chuck is slidably connected to a pressure rod corresponding to the through hole, and a spring is arranged between the pressure rod and the chuck; the end of the pressure rod protrudes from the surface of the chuck, and the protruding part is squeezed by the inner wall of the male head and slides toward the corresponding through hole of the chuck.

[0011] Optionally, it also includes a retaining ring; the connecting disc is fixed with the retaining ring; the male head is provided with a plurality of air holes I; the connecting sleeve is provided with a plurality of air holes II, and when the female head is connected to the male head, the air holes I and the air holes II are aligned, and the retaining ring seals the air holes I.

[0012] Optionally, the retaining ring is entirely red.

[0013] Optionally, the outer side of the retaining ring has reflective paint.

[0014] The beneficial effect of the present invention is that when the contact column and the connecting ring are overloaded and generate abnormal heat, the continuous heat is transferred to the expansion ring through the heat-conducting ring. After being heated, the expansion ring gradually extends to the right, causing the expansion ring to squeeze and push the round rod to the right, and then the round rod pushes the connecting plate and the connecting ring to the right. The connecting plate slides along the inner side of the male head, disconnecting the connecting ring and the slot, cutting off the circuit to prevent further temperature increase, and avoiding the occurrence of spontaneous combustion.

[0015] When used in an open environment, the internal structure can be prevented from being kicked or stepped on and damaged. After the circuit is automatically cut off, people can also be prevented from accidentally touching the uncooled thermal ring and connecting ring and causing burns. The magnetic structure does not completely lock the two, and when encountering an external force that exceeds the limit, it can also detach itself to avoid breakage and damage.

[0016] When the cable body is inserted into the male connector and docked with the connecting ring, it is difficult to align them. To solve this problem, the chuck is initially located at the end of the male connector. The user passes the cable body of the connector through the chuck. Then, the user pushes the chuck toward the connecting ring. The chuck will first fully enter the male connector. At this time, the pressure rod moves toward the center of the chuck under the limit of the inner wall of the male connector, squeezing the cable body and firmly clamping it. The chuck then acts as a clamping device, replacing tools such as needle-nose pliers used by humans to secure all cable bodies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1, a safety cable connector with an anti-drop function, such as Figures 1-8As shown, it includes a female connector 1, a connecting sleeve 12, and a male connector 2; the female connector 1 is fixedly connected to a contact pin 11; the contact pin 11 has a plurality of slots 1001; the connecting sleeve 12 is connected to the surface of the female connector 1; the connecting sleeve 12 is slidably connected to the male connector 2, and a plurality of guide strips 21 are fixed to the surface of the male connector 2; the inner side of the connecting sleeve 12 has a groove corresponding to the guide strip 21, and the deepest part of the groove, at the end of the guide strip 21, is provided with a magnetic attraction member that can cooperate with each other;

[0028] It also includes a heat-conducting ring 101, a hollow tube 102, a round rod 103, an expansion ring 104, a connecting disk 108, a connecting ring 109, a connector 105 and a threaded ring 106; the contact column 11 of the female head 1 is fixedly connected to the heat-conducting ring 101; the heat-conducting ring 101 is fixedly connected to two hollow tubes 102; each hollow tube 102 is slidably connected to a round rod 103; an expansion ring 104 is provided in each hollow tube 102, and the expansion ring 104 is located between the heat-conducting ring 101 and the round rod 103; the male head 2 is slidably connected to the connecting disk 108; the connecting disk 108 is fixedly connected to a number of connecting rings 109, and the number and position of the connecting rings 109 correspond to the slots 1001 of the contact column 11; the male head 2 is detachably connected to the threaded ring 106; the threaded ring 106 is rotatably connected to the connector 105; the connector 105 is used to pass through the cable body 107.

[0029] Each connecting ring 109 is fixedly connected to a plurality of protruding rings 1091 . When the connecting ring 109 and the slot 1001 are connected to each other, the protruding rings 1091 are inserted into the slot 1001 , thereby enhancing the connection stability between the connecting ring 109 and the slot 1001 .

[0030] The female connector 1, the connecting sleeve 12 and the male connector 2 are all made of heat-insulating materials, thereby blocking the heat exchange between the inside and the outside, preventing the heat-conducting ring 101 from accidentally triggering the round rod 103 under the influence of external heat, and preventing the internal heat from diffusing to the outside and causing harm in the thermal runaway state.

[0031] A sealing ring is provided inside the connecting sleeve 12 to enhance the sealing performance between the male connector 2 and the connecting sleeve 12 after the male connector 2 and the connecting sleeve 12 are connected.

[0032] The outer surface of the threaded ring 106 is provided with a rough texture, thereby increasing the friction of the outer surface of the threaded ring 106 , making it easier for the user to screw the threaded ring 106 .

[0033] When in use, the user needs to first grasp the cable body 107 and insert it into the connecting ring 109 for connection. Then, the user grasps the connector 105 and moves it against the end of the male connector 2. Then, the user screws the threaded ring 106 so that the threaded ring 106 and the male connector 2 are screwed and fixed, thereby connecting the connector 105 to the male connector 2. When the connector 105 moves against the male connector 2, it will be pushed toward the other end of the male connector 2 by the cable body 107, the connecting ring 109 and the connecting plate 108. Then, the user puts the female connector 105 into the socket 106. Place the male connector 2 in a horizontal state, align the guide bar 21 with the groove inside the connecting sleeve 12, and then push the male connector 2 horizontally to the left into the connecting sleeve 12. The guide bar 21 moves along the groove inside the connecting sleeve 12 to the end. The magnetic attraction piece at the end of the guide bar 21 and the magnetic attraction piece in the groove inside the connecting sleeve 12 are attracted to each other, connecting the male connector 2 and the female connector 1 together. At this time, the connecting ring 109 enters the slot 1001, and the contact column 11 is connected to the connecting ring 109 of the connecting cable body 107. Figure 3 shown.

[0034] When the contact column 11 and the connecting ring 109 are overloaded and abnormally heated, the continuous heat is transferred to the expansion ring 104 through the heat-conducting ring 101. After being heated, the expansion ring 104 gradually extends to the right, causing the expansion ring 104 to squeeze and push the round rod 103 to the right, thereby causing the round rod 103 to push the connecting disk 108 and the connecting ring 109 to the right. The connecting disk 108 slides along the inside of the male head 2, disconnecting the connecting ring 109 and the slot 1001, cutting off the circuit to prevent further heating and avoid spontaneous combustion. Moreover, because the connecting disk 108 can slide inside the male head 2, it is the connecting disk 108 that moves. Because the magnetic attraction part at the end of the guide bar 21 and the magnetic attraction part in the groove on the inner side of the connecting sleeve 12 are attracted to each other, the female head 1 and the male head 2 will not separate. Figure 7 and Figure 8 As shown; the tightly plugged female connector 1 and male connector 2 can protect the internal structure. When used in an open environment, the internal structure can be prevented from being kicked or stepped on and damaged. After the circuit is automatically cut off, it can also prevent people from accidentally touching the uncooled heat-conducting ring 101 and the connecting ring 109 and causing burns. The magnetic structure does not completely lock the two. When encountering an external force that exceeds the limit, it can also detach itself to avoid breakage and damage.

[0035] Example 2, based on Example 1, Figure 2-Figure 5 and Figure 7 As shown, it also includes a chuck 201 and a screw 202; the male head 2 is slidably connected to a chuck 201, and the chuck 201 has a plurality of through holes for fixing the cable body 107, and the chuck 201 is located on the side of the connecting plate 108 away from the contact column 11; the chuck 201 is rotatably connected to a screw 202, and the screw 202 forms a threaded screw with the connecting plate 108 for fixing.

[0036] It also includes a pressure rod 203; each chuck 201 is slidably connected to a pressure rod 203 corresponding to the through hole, and a spring is provided between the pressure rod 203 and the chuck 201; the end of the pressure rod 203 protrudes from the surface of the chuck 201, and the protruding part is squeezed by the inner wall of the male head 2 and slides toward the direction of the corresponding through hole of the chuck 201.

[0037] Considering that the cable body 107 of some connectors 105 is relatively thin and soft, the connection end must not be too short under normal circumstances, otherwise it will be difficult to adjust. For cables that are not easy to bend, just straighten all the cables to a state parallel to the connection ring 109 and then roughly align each connection ring 109 to easily complete the docking. However, such long and thin cables will cause themselves to bend and sag, and it is not convenient to control a single cable with tools, not to mention that there are multiple cables and the connection ring 109 is located in the male connector 2. Therefore, when the cable body 107 is inserted deep into the male connector 2 and docked with the connection ring 109, it is difficult to align them with each other. To solve this problem, the chuck 201 is initially located at the end of the male connector 2, such as Figure 4 and Figure 5 As shown, the user passes the cable body 107 of the connector 105 through the chuck 201 , and then pushes the chuck 201 toward the connection disk 108 .

[0038] The chuck 201 will first completely enter the inside of the male head 2. At this time, the pressure rod 203 moves toward the center of the chuck 201 under the limit of the inner wall of the male head 2, squeezing the cable body 107 to tightly clamp the cable body 107. Then, the chuck 201 serves as a clamping tool to replace tools such as needle-nose pliers used by people to fix all cable bodies 107.

[0039] Only a length of the cable body 107 that does not bend needs to be passed through the chuck 201. Then, after the above-mentioned fixing process, the cable body 107 between the chuck 201 and the connecting disk 108 will be in a relatively straight and easy-to-connect state. The user does not need to use tools such as needle-nosed pliers to adjust and align the connecting rings 109 deeper in the male connector 2 one by one. The chuck 201 is located at a position slightly outside the end of the male connector 2, and the user's field of vision is not easily blocked by tools such as needle-nosed pliers, thereby reducing the difficulty of connecting delicate cables. After the fixing is completed, the chuck 201 is further pushed toward the connecting disk 108. The chuck 201 will stably guide all the ends of the cable body 107 to be inserted into the connecting ring 109. Then, the screw 202 is tightened to connect the chuck 201 and the connecting disk 108. The subsequent pushing action will cause the chuck 201 and the connecting disk 108 to move together toward the side close to the contact column 11 until the connecting ring 109 is completely connected to the slot 1001, completing the connection work.

[0040] Example 3, based on Example 1, Figure 3 and Figure 6-Figure 8As shown, it also includes a retaining ring 301; the connecting disk 108 is fixed with the retaining ring 301; the male head 2 is provided with a plurality of air holes I22; the connecting sleeve 12 is provided with a plurality of air holes II121, and when the female head 1 is connected to the male head 2, the air holes I22 and the air holes II121 are aligned, and the retaining ring 301 seals the air holes I22.

[0041] The retaining ring 301 is entirely red, which has a striking effect.

[0042] The outer side of the retaining ring 301 is coated with reflective paint.

[0043] When the connecting disk 108 and the connecting ring 109 move to the right and disengage from the contact column 11, the connecting disk 108 drives the retaining ring 301 to move to the right, so that the retaining ring 301 releases the obstruction of the air vent I 22, and then the heat can be dissipated outward through the air vent I 22 and the air vent II 121, thereby dissipating the heat from the contact column 11 and the connecting ring 109; during normal use, the retaining ring 301 can not only prevent the invasion of external dust, but also after the retaining ring 301 releases the obstruction of the air vent I 22, when the maintenance personnel observe through the air vent I 22 and the air vent II 121, if they do not see the retaining ring 301 coated with reflective paint, it means that the cable connector is automatically disconnected, which is convenient for the maintenance personnel to quickly identify the faulty cable from a large number of cables, and then repair the faulty cable.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
