Description

Technical Field

[0001] The present invention relates to the technical field of electrical components, and particularly to a detachable insulating terminal. Background Technique

[0002] An insulating terminal is a component used to connect cables and electrical equipment, usually composed of conductive materials and insulating materials. Its main function is to transfer current from one conductor to another while preventing current leakage or short circuit.

[0003] In the prior art, a Chinese utility model with the publication number CN222126982U discloses a detachable insulating terminal. Since the spring at the top of the elastic block will exert a downward extrusion on the elastic block due to its own spring, the metal block at the top of the elastic block can be in close contact with the wire or cable, so that it can conduct electricity with the metal layers inside the lower housing and the upper housing, which is beneficial to complete the electrical connection.

[0004] Currently, after the insulating terminal electrically connects the electrode and the cable, due to long-term use, local damage to the insulating terminal will occur, and then it needs to be disassembled and replaced. The insulating terminal not only needs to be removed from the electrode, but also needs to be separated from the cable. The disassembly and replacement of traditional insulating terminals are not only complex in operation, but also have poor stability after reconnection, with relatively large potential safety hazards. For this reason, the present invention proposes a detachable insulating terminal to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0033] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 11, the present invention provides a technical solution:

[0035] Example 1, a detachable insulating terminal, comprising: a conductor cylinder 1.

[0036] Specifically, a conductor joint 2 is fixed at one end of the conductor cylinder 1. The conductor joint 2 is flat and in a "U" shape. On the upper and lower sides of the two front ends of the conductor joint 2, limiting bumps 21 are fixed. The limiting bumps 21 are located at the front edge of the conductor joint 2. On the upper and lower sides of the conductor joint 2, auxiliary connectors 3 are provided, and the two auxiliary connectors 3 are symmetrically distributed. The conductor joint 2 is horizontally inserted into the gap between the two auxiliary connectors 3. Then, the limiting bumps 21 are buckled at the edge of the auxiliary connectors 3. At this time, the conductor joint 2 cannot be pulled out reversely from between the two auxiliary connectors 3;

[0037] Furthermore, the auxiliary connector 3 includes a circular gasket 301 and a special-shaped ring 302. The special-shaped ring 302 is pressed and attached to the conductor joint 2. One side of the special-shaped ring 302 is bent to form a bending inclined surface 303 and is fixedly connected to the edge of the circular gasket 301. As Figure 3 shown, there is a gap between the circular gasket 301 and the special-shaped ring 302. The auxiliary connector 3 itself has a certain elastic deformation ability. After the limiting bump 21 passes through the gap between the two special-shaped rings 302, it is buckled at the edge of the special-shaped ring 302. When the conductor joint 2 and the limiting bump 21 pass through between the two auxiliary connectors 3, the limiting bump 21 can exert pressure on the bending inclined surface 303, causing the two special-shaped rings 302 to move away from each other and undergo elastic deformation until the limiting bump 21 passes over the special-shaped ring 302. Then, the special-shaped ring 302 can automatically recover its deformation and press on the surface of the conductor joint 2. At this time, the limiting bump 21 is buckled at the edge of the special-shaped ring 302, which can prevent the conductor joint 2 from moving reversely and detaching from the auxiliary connector 3. In addition, the auxiliary connector 3 is movably sleeved on the outside of the electrode post 4. The lower end of the electrode post 4 is fixed on the workpiece 41. A fastening nut 42 is threadedly sleeved on the upper outer side of the electrode post 4, and the fastening nut 42 presses the auxiliary connector 3 from top to bottom. The middle part of the auxiliary connector 3 is a round hole. After the auxiliary connector 3 is sleeved and connected with the electrode post 4, it is pressed and fixed by the fastening nut 42 and will not detach from the electrode post 4. The limiting bump 21 on the conductor joint 2 can quickly insert between the two auxiliary connectors 3 from the bending inclined surface 303 and maintain its stable position after insertion and will not be easily pulled out. When it is necessary to separate the conductor joint 2 from the electrode post 4, the operator only needs to rotate the conductor joint 2 180 degrees between the two auxiliary connectors 3 so that the limiting bump 21 corresponds to the bending inclined surface 303, and then pull the conductor joint 2 to pull out the conductor joint 2 from between the two auxiliary connectors 3 and complete the separation of the conductor joint 2 from the electrode post 4. Therefore, the connection and disassembly processes between the conductor joint 2 and the electrode post 4 of this device are both convenient and simple;

[0038] Secondly, an insulating sleeve 5 is movably sleeved outside the conductor cylinder 1. A flexible pressing plate 6 is arranged in the inner cavity of the conductor cylinder 1. One side edge of the flexible pressing plate 6 is rotatably connected to the inner wall of the conductor cylinder 1. A sliding seat 51 is fixed on the inner wall of the insulating sleeve 5. The sliding seat 51 movably penetrates through the side wall of the conductor cylinder 1 and is rotatably connected to the other side edge of the flexible pressing plate 6. The insulating sleeve 5 rotates and drives the flexible pressing plate 6 to rotate around one side edge thereof through the sliding seat 51, and then presses and fits on the cable in the inner cavity of the conductor cylinder 1. As Figure 4 and Figure 5 shown, when the cable is connected to the conductor cylinder 1, the copper wire after peeling the cable is exposed and inserted into the lower region in the inner cavity of the conductor cylinder 1. At this time, the insulating sleeve 5 is rotated counterclockwise to drive the other side edge of the flexible pressing plate 6 to rotate counterclockwise along the inner wall of the conductor cylinder 1. The middle part of the flexible pressing plate 6 gradually approaches and presses on the copper wire of the cable until the flexible pressing plate 6 presses the copper wire of the cable tightly. At this time, the lower side of the copper wire closely adheres to the lower side of the inner wall of the conductor cylinder 1. On the one hand, the electrical connection between the copper wire and the conductor cylinder 1 is realized, and on the other hand, the relative fixation between the cable and the conductor cylinder 1 is ensured. When it is necessary to separate the conductor cylinder 1 from the cable, only the insulating sleeve 5 needs to be rotated in the reverse direction to separate the flexible pressing plate 6 from the copper wire of the cable, and the cable can be drawn out from the inner cavity of the conductor cylinder 1.

[0039] In order to prevent the auxiliary connecting piece 3 from rotating, a ring tooth 35 is fixedly arranged on the lower surface of the ring gasket 301 located below the conductor joint 2 of the present application, and the ring tooth 35 tightly clamps the surface of the fastening nut 42. Combining Figure 1 and Figure 3 shown, when the fastening nut 42 presses the two auxiliary connecting pieces 3 from top to bottom, the ring tooth 35 can clamp the fastening nut 42 to increase the friction between the two, preventing the auxiliary connecting piece 3 from rotating around the electrode post 4. Therefore, the staff can rotate the conductor joint 2 alone to realize the relative rotation between the conductor joint 2 and the auxiliary connecting piece 3.

[0040] In order to prevent relative rotation between the two auxiliary connecting pieces 3, the present application also has a flange 31 fixed at the edge of the ring gasket 301. Insertion plates 32 and receiving plates 33 are respectively fixed at the edges of the two flanges 31, and both the insertion plates 32 and the receiving plates 33 are vertically arranged. A receiving slot 34 is formed on the upper surface of the insertion plate 32. The insertion plate 32 is movably inserted into the inner cavity of the receiving slot 34 from top to bottom and is adapted to it. As Figure 2As shown, the plug board 32 can slide in the up and down directions along the inner cavity of the receiving slot 34, so the two auxiliary connectors 3 can move closer to or away from each other, but the two auxiliary connectors 3 will not rotate relative to each other, which avoids the possibility of the two bending slopes 303 being misaligned with each other. In addition, a positioning structure is provided between the special-shaped ring 302 and the conductor connector 2. The positioning structure is provided to increase the resistance to relative rotation between the conductor connector 2 and the auxiliary connector 3 to avoid the conductor connector 2 from easily rotating after installation. The conductor connector 2 and the auxiliary connector 3 can be driven to rotate relative to each other only when and when the staff applies external force to the conductor connector 2.

[0041] To describe the positioning structure in detail:

[0042] The positioning structure of the present application includes friction lines formed on the surface of the special-shaped ring 302, and the friction lines are attached to the surface of the conductor connector 2. Since the fastening nut 42 is in a compression state on the auxiliary connector 3, the two special-shaped rings 302 can respectively compress the upper and lower surfaces of the conductor connector 2. At this time, the setting of the friction lines on the special-shaped ring 302 can effectively increase the friction force generated between the special-shaped ring 302 and the conductor connector 2, thereby preventing the conductor connector 2 from rotating between the two auxiliary connectors 3.

[0043] Embodiment 2: The positioning structure of the present application may also include two positioning grooves 22 respectively provided on the upper and lower surfaces of the conductor connector 2, wherein the inner cavity of the positioning groove 22 is clamped with a positioning protrusion 23 adapted thereto, and the positioning protrusion 23 is fixed on the corresponding special-shaped ring 302, such as Figure 11 As shown, when the conductor connector 2 is inserted between the two special-shaped rings 302, the positioning protrusion 23 on the special-shaped ring 302 can just be buckled in the inner cavity of the positioning groove 22 on the surface of the conductor connector 2, thereby ensuring the stability of the relative position between the conductor connector 2 and the special-shaped ring 302, and preventing the conductor connector 2 from rotating between the two auxiliary connectors 3. When the staff applies external force to drive the conductor connector 2 to rotate, the positioning protrusion 23 and the positioning groove 22 are misaligned and press against the surface of the conductor connector 2. At this time, the special-shaped ring 302 can automatically deform away from the conductor connector 2 until the conductor connector 2 rotates one hundred and eighty degrees and the staff pulls the conductor connector 2 out from between the two special-shaped rings 302.

[0044] In order to install and connect the flexible clamping plate 6, the present application also has shaft rod 1 62 and shaft rod 2 64 respectively arranged on both sides of the flexible clamping plate 6, and sleeve 1 63 and sleeve 2 65 are respectively sleeved on the outer sides of shaft rod 1 62 and shaft rod 2 64, and sleeve 1 63 and sleeve 2 65 are respectively fixed to the edges of both sides of the flexible clamping plate 6, and the inner side wall of the conductor cylinder 1 is fixed with a hinge support 13, and the hinge support 13 is movably sleeved on the outer side of shaft rod 2 64, and the sliding seat 51 is movably sleeved on the outer side of shaft rod 1 62, combined withFigure 6 , Figure 7 and Figure 8 As can be seen from Figure 7 and Figure 8 , there are multiple hinge supports 13, sliding seats 51, first sleeves 63 and second sleeves 65, and they are evenly distributed along the length direction of the conductor cylinder 1. Therefore, the flexible pressing plate 6 can be stably installed in the inner cavity of the conductor cylinder 1, and the inner cavity of the conductor cylinder 1 can rotate and deform, but the flexible pressing plate 6 will not break away from the inner cavity of the conductor cylinder 1. That is to say, after the flexible pressing plate 6 presses the copper wire of the cable, even if the cable is pulled due to uncertain external factors, the cable will not break away from the conductor cylinder 1.

[0045] In order to limit the structural dimensions of the flexible pressing plate 6, the cross-section of the flexible pressing plate 6 of the present application is an upwardly convex arc structure. The flexible pressing plate 6 is made of a rigid non-metallic material that can undergo elastic deformation. A non-slip layer 61 is fixedly arranged in the middle of the lower surface of the flexible pressing plate 6 to increase the friction between the flexible pressing plate 6 and the copper wire of the cable and improve the stability after the cable is connected. The width of the flexible pressing plate 6 is greater than the diameter of the conductor cylinder 1 and less than half of the circumference of the conductor cylinder 1. As Figure 4 and Figure 8 As can be seen from Figure 4 and Figure 8 , the left side of the flexible pressing plate 6 can only move circumferentially along the inner wall of the conductor cylinder 1, while the position of the right side of the flexible pressing plate 6 remains fixed. As the distance between the two side edges of the flexible pressing plate 6 changes, the flexible pressing plate 6 itself will undergo elastic deformation. Therefore, after the flexible pressing plate 6 rotates clockwise around its right side to the maximum stroke, the flexible pressing plate 6 can deform to be concentric with the conductor cylinder 1 and completely fit on the inner wall of the conductor cylinder 1. At this time, the entire area of the inner cavity of the conductor cylinder 1 can insert the copper wire of the cable. Therefore, the present device will not affect the plug-in connection between the cable and the conductor cylinder 1 due to the setting of the flexible pressing plate 6.

[0046] In order to position the rotation of the insulating sleeve 5, the present application also has a guiding chute 11 opened on the surface of the conductor cylinder 1 along its circumferential direction, and the central angle of the guiding chute 11 is less than 180 degrees. A helical tooth groove 12 is opened on one inner wall of the guiding chute 11. The sliding seat 51 movably penetrates the guiding chute 11, and the widths of the two are the same. The width of the avoiding chute 511 is greater than the wall thickness of the conductor cylinder 1. As Figure 6 and Figure 7 As shown in Figure 6 and Figure 7 , the cooperation between the sliding seat 51 and the guiding chute 11 ensures that the insulating sleeve 5 can rotate a certain angle on the outside of the conductor cylinder 1. And an avoiding chute 511 is arranged at one side edge of the sliding seat 51 (as Figure 10As shown, the inclined surface at the bottom of the avoidance chute 511 is parallel to the inclined surface at the bottom of the helical tooth groove 12. Therefore, the sliding seat 51 can move a certain distance closer to or away from the helical tooth groove 12. That is to say, when the sliding seat 51 is away from the helical tooth groove 12, the sliding seat 51 will only slide within the inner cavity of the guiding chute 11 and will not be affected by the helical tooth groove 12. When the sliding seat 51 approaches the helical tooth groove 12, the helical tooth groove 12 can limit the sliding seat 51, so that the sliding seat 51 and the insulating sleeve 5 can only rotate counterclockwise and cannot rotate clockwise. Therefore, by controlling the sliding of the insulating sleeve 5 outside the conductor cylinder 1 and driving the sliding seat 51 to approach the helical tooth groove 12, the cooperation between the helical tooth groove 12 and the sliding seat 51 can position the rotation of the insulating sleeve 5 and prevent the insulating sleeve 5 from rotating clockwise.

[0047] To prevent the insulating sleeve 5 from sliding easily outside the conductor cylinder 1, the present application also has a limit retaining ring 14 fixed to the outer side of one end of the conductor cylinder 1, and a limit convex ring 52 fixed to the outer side of one end of the insulating sleeve 5. A compression spring 9 is arranged between the limit convex ring 52 and the limit retaining ring 14, and the compression spring 9 is sleeved on the outer side of the conductor cylinder 1. The two ends of the compression spring 9 respectively abut against the limit convex ring 52 and the limit retaining ring 14. Anti-slip lines 53 are also provided on the outer side wall of the insulating sleeve 5 to facilitate the staff to twist the insulating sleeve 5 to rotate. As Figure 9 shown, the compression spring 9 provides a thrust force so that the limit convex ring 52 always has a tendency to slide away from the limit retaining ring 14. Therefore, the insulating sleeve 5 always has a tendency to slide along the length direction of the conductor cylinder 1. Combining Figure 6 and Figure 7 shown, the sliding seat 51 always has a tendency to move closer to the helical tooth groove 12. Therefore, when connecting or disassembling the conductor cylinder 1 of the present device to the cable, the specific operation process is as follows:

[0048] ① The staff inserts the copper wire of the cable into the lower region of the inner cavity of the conductor cylinder 1, and then rotates the insulating sleeve 5 counterclockwise. At this time, the left side of the flexible pressing plate 6 driven by the insulating sleeve 5 rotates counterclockwise along the inner wall circumference of the conductor cylinder 1, and then presses the middle of the flexible pressing plate 6 against the copper wire of the cable, realizing the connection between the cable and the conductor cylinder 1;

[0049] ② After the cable connection is completed, the insulating sleeve 5 is loosened. Due to the thrust of the compression spring 9 on the insulating sleeve 5, the sliding seat 51 can be stuck into the helical tooth groove 12. Therefore, the helical tooth groove 12 can prevent the sliding seat 51 from rotating clockwise along the inner cavity of the guiding chute 11. Therefore, the position of the flexible pressing plate 6 remains stable and can realize the stable pressing of the cable;

[0050] ③When it is necessary to remove the cable from the conductor cylinder 1, the staff only needs to slide the insulating sleeve 5 on the outside of the conductor cylinder 1 and compress the compression spring 9. At this time, the sliding seat 51 is separated from the helical groove 12, and the insulating sleeve 5 can be easily rotated clockwise, thereby releasing the compression of the flexible pressing plate 6 on the copper wire of the cable, and the cable can be easily separated from the conductor cylinder 1.

[0051] In order to insulate the conductor cylinder 1, the present application further has a telescopic sleeve 8 sleeved outside the compression spring 9. The middle of the telescopic sleeve 8 is wavy, and the telescopic sleeve 8 itself has certain elastic telescopic properties, which can cooperate with the sliding of the insulating sleeve 5 on the outside of the conductor cylinder 1. Both ends of the telescopic sleeve 8 are folded inward and respectively buckled on the outside of the limit convex ring 52 and the limit retaining ring 14. An insulating sleeve layer 7 is fixedly sleeved on the outside of the other end of the conductor cylinder 1. As Figure 9 shown, the insulating sleeve layer 7, the insulating sleeve 5 and the telescopic sleeve 8 can completely cover the outer surface of the conductor cylinder 1, so as to achieve the insulation effect. It should be noted that one end of the insulating sleeve layer 7 opens outward and is movably sleeved on the outside of the other end of the insulating sleeve 5. There is a certain overlapping area between the insulating sleeve layer 7 and the insulating sleeve 5 to ensure that when the insulating sleeve 5 slides on the outside of the conductor cylinder 1, the conductor cylinder 1 between the insulating sleeve layer 7 and the insulating sleeve 5 will not be exposed.
