Description

Technical Field

[0001] This application relates to the technical field of couplers, and in particular to a metering box coupler and its integration method. Background Technology

[0002] A coupler is a device that connects two or more independent systems by physical or electromagnetic means. Couplers can be used in metering boxes and are mainly used for power distribution.

[0003] In related technologies, the coupler includes a housing with multiple mounting holes and a plug interface. The plug interface and the mounting holes are interconnected, and a connector is provided inside the plug interface. When a wire is inserted into the mounting hole, the connector and the wire are connected.

[0004] Because the wires are inserted into the coupler, external moisture can easily enter the coupler along the outer surface of the wires, allowing moisture to seep into the connector and thus affecting the normal use of the coupler. Summary of the Invention

[0005] To address the issue of moisture easily entering the coupler along the wires, this application provides a metering box coupler and its integration method.

[0006] This application provides a metering box coupler and its integration method, which adopts the following technical solution: A metering box coupler includes a housing with multiple mounting holes, an elastic block with a through hole for a wire to pass through, the through hole extending to the outer surface of the elastic block, and a limiting ring with a through hole. When the elastic block is located inside the limiting ring, the limiting ring blocks the side through which the through hole passes.

[0007] By adopting the above technical solution, the staff first installs the elastic block on the housing, then passes the wire through the perforation and installs it in the mounting hole. Finally, the staff pulls the limiting ring open from the through hole, so that the limiting ring can be fitted onto the elastic block and the wire, so that the inner wall of the limiting ring and the hole wall of the perforation abut against the wire, thereby reducing the distance between the wire and the elastic block and reducing the possibility of moisture flowing along the outer surface of the wire towards the coupler.

[0008] Optionally, the elastic block is provided with multiple elastic strips, two of which are located between two adjacent wires, and the limiting ring is provided with a limiting block located between two adjacent elastic strips; when the limiting block is located between two adjacent elastic strips, the elastic strips abut against the wires.

[0009] By adopting the above technical solution, the limiting block is inserted between two adjacent elastic strips. Since the two elastic strips are located between two adjacent wires, the limiting block can cause the elastic strips to deform, allowing the elastic strips to smoothly abut against the wires. This allows the wires to abut against the elastic strips even when the surface of the elastic block is far away from the elastic block, further reducing the gap between the wires and the limiting ring.

[0010] Optionally, the elastic strip is provided with a receiving groove for the insertion of a limiting block.

[0011] By adopting the above technical solution, the limiting block is inserted into the receiving groove, so that the limiting ring can be fixed on the elastic strip, reducing the possibility of the limiting ring moving on the elastic block, and so that the limiting ring and the elastic block can stably fix the wire.

[0012] Optionally, an operating ring is rotatably connected to the outer side of the limiting ring, and the operating ring has an operating hole; when the operating ring blocks the through hole, the operating ring restricts the movement of the limiting ring.

[0013] By adopting the above technical solution, the operating hole is connected by a perforation, allowing the elastic block to be located within the operating ring and the limiting ring. Then, the operator rotates the operating ring to block the perforation, thereby restricting the limiting ring from opening and ensuring that the elastic block can be stably located within the operating ring, reducing the possibility of the elastic block detaching from the perforation.

[0014] Optionally, the limiting ring is provided with a fixing strip, which is arc-shaped and abuts against the side of the wire away from the elastic block.

[0015] By adopting the above technical solution, since the fixing strip is set in an arc shape, the fixing strip can abut against the wire, so that the fixing strip and the elastic block can stably abut against the outer surface of the wire, reducing the possibility of moisture entering the coupler along the outer surface of the wire.

[0016] Optionally, the limiting ring has a fixing hole, a fixing block is slidably connected in the fixing hole, the fixing strip is set on the fixing block, and the operating ring has a positioning block for inserting into the fixing hole. The fixing block is located on the moving path of the positioning block inserting into the fixing hole. When the positioning block is inserted into the fixing hole, the operating ring is fixed on the limiting ring, and the fixing strip abuts against the side of the wire away from the elastic block.

[0017] By adopting the above technical solution, the operator rotates the operating ring to insert the positioning block into the fixing hole. Since the fixing block is located on the moving path of the positioning block inserted into the fixing hole, the positioning block drives the fixing block to move, thereby allowing the fixing block to drive the fixing strip to abut against the wire, making the connection between the fixing strip and the wire more compact, increasing the connection strength between the wire and the coupler, and further reducing the possibility of moisture entering the coupler along the outer surface of the wire.

[0018] Optionally, the fixing strip is provided with a stop strip, the stop strip is provided with a stop protrusion, and the elastic strip is provided with a stop groove for the stop protrusion to be inserted; when the stop protrusion is inserted into the stop groove, the stop strip is located on the side of the elastic strip away from the wire.

[0019] By adopting the above technical solution, the stop protrusion is inserted into the stop groove, and the stop strip is located on the side of the elastic strip away from the conductor. This causes the stop strip to deform towards the conductor, allowing the stop strip and the elastic strip to squeeze the conductor, further reducing the possibility of moisture entering along the outer surface of the conductor.

[0020] Optionally, the limiting ring is provided with a limiting spring, which is located on the side of the fixing strip away from the wire, and the limiting spring is used to drive the fixing strip to squeeze the wire.

[0021] By adopting the above technical solution, the limiting spring is located on the side of the fixing strip away from the wire, so that the limiting spring can drive the fixing strip to squeeze the wire, allowing the fixing strip to deform in the direction of the wire, thereby further reducing the gap between the fixing strip and the wire.

[0022] A coupler integration method includes the following steps: Install the elastic block on the housing, and pass the wire through the through hole into the mounting hole; Pull the limiting ring open from the through hole, and then place the elastic block inside the limiting ring to complete the assembly of the limiting ring and the elastic block.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The operator first installs the elastic block on the housing, then passes the wire through the through hole and installs it in the mounting hole. Finally, the operator pulls the limiting ring open from the through hole so that the limiting ring can fit on the elastic block and the wire, so that the inner wall of the limiting ring and the hole wall of the through hole abut against the wire, thereby reducing the distance between the wire and the elastic block and reducing the possibility of moisture flowing along the outer surface of the wire towards the coupler.

[0024] 2. By inserting a limiting block between two adjacent elastic strips, since the two elastic strips are located between two adjacent wires, the limiting block can cause the elastic strips to deform, allowing the elastic strips to smoothly abut against the wires. This allows the wires to abut against the elastic strips even when they are away from the surface of the elastic block, further reducing the gap between the wires and the limiting ring.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This embodiment discloses a metering box coupler. (Refer to...) Figure 1 and Figure 2 A metering box coupler includes a housing 1 with multiple mounting holes 11 and a connector 12 connected to the mounting holes 11. A connector 121 is provided inside the connector 12 for connecting wires.

[0029] Reference Figure 2 and Figure 3 The housing 1 has an elastic block 2, and multiple through holes 21 are formed on the surface of the elastic block 2. The multiple through holes 21 are arranged in an array along the elastic block 2, and the through holes 21 allow wires to pass through. The housing 1 has a mounting groove 13, and a mounting block 22 is fixedly connected to the end face of the elastic block 2. The mounting block 22 is used to insert into the mounting groove 13. When the mounting block 22 is inserted into the mounting groove 13, the elastic block 2 is fixed to the housing 1, and at this time the through holes 21 are connected to the mounting holes 11.

[0030] Reference Figure 3 The housing 1 is provided with a limiting ring 3, and a through hole 31 is opened on the surface of the limiting ring 3. The limiting ring 3 can be pulled open so that the limiting ring 3 can be sleeved on the elastic block 2. The operator pulls the limiting ring 3 so that the limiting ring 3 is sleeved on the outer surface of the elastic block 2.

[0031] Reference Figure 3Multiple elastic strips 23 are fixedly connected to the surface of the elastic block 2. These elastic strips 23 have elastic deformation capability, and two elastic strips 23 are located between two adjacent conductors. Multiple limiting blocks 32 are fixedly connected to the inner wall of the limiting ring 3. These limiting blocks 32 are arranged in a circumferential array along the limiting ring 3, and can be inserted between two adjacent elastic strips 23. When a limiting block 32 is inserted between two adjacent elastic strips 23, it drives the elastic strip 23 to deform, causing the elastic strip 23 to deform towards the conductor.

[0032] Reference Figure 3 A receiving groove 231 is provided on the surface of the elastic strip 23 for the insertion of the limiting block 32. When the limiting block 32 is inserted into the receiving groove 231, the limiting ring 3 is fixed on the elastic block 2 to reduce the possibility of the limiting ring 3 moving along the length of the conductor.

[0033] Reference Figure 4 The inner wall of the limiting ring 3 has multiple fixing holes 33, which are arranged in a circumferential array along the limiting ring 3. A fixing block 331 is slidably connected in the fixing hole 33, and a fixing strip 332 is integrally formed on the fixing block 331. The fixing strip 332 is arc-shaped and protrudes away from the wire.

[0034] Reference Figure 4 Multiple limiting springs 34 are fixedly connected to the inner wall of the limiting ring 3. The limiting springs 34 have elastic deformation capability and are located on the side of the fixing strip 332 away from the wire. The limiting springs 34 deform in the direction of the wire, causing the limiting springs 34 to drive the fixing strip 332 to squeeze the wire.

[0035] Reference Figure 4 Two stop strips 35 are fixedly connected to the surface of the fixing strip 332 away from the conductor. One stop strip 35 is located on one end of the fixing strip 332, and the other stop strip 35 is located on the other end of the fixing strip 332. When the elastic strip 23 abuts against the conductor, the stop strip 35 is located on the side of the elastic strip 23 away from the conductor.

[0036] Reference Figure 2 and Figure 4 A stop protrusion 351 is fixedly connected to the end face of the stop strip 35 near the conductor, and a stop groove 232 is opened on the surface of the elastic strip 23 for the stop protrusion 351 to be inserted. When the stop protrusion 351 is inserted into the stop groove 232, the stop strip 35 abuts against the elastic strip 23 away from the surface of the conductor, and at this time the elastic strip 23 squeezes the conductor.

[0037] Reference Figure 4An operating ring 4 is rotatably connected to the limiting ring 3. The diameter of the operating ring 4 is larger than that of the limiting ring 3, meaning that the operating ring 4 is fitted onto the limiting ring 3. The operating ring 4 has an operating hole 41, which allows the limiting ring 3 to be pulled open. When the operating hole 41 aligns with the through hole 31, both the operating ring 4 and the limiting ring 3 can be pulled open. When the operating ring 4 blocks the through hole 31, it restricts the limiting ring 3 from being pulled open, making it difficult for the elastic block 2 to detach from the limiting ring 3.

[0038] Reference Figure 4 The staff first aligns the through hole 31 and the operating hole 41, then the driving block passes through the operating hole 41 and the through hole 31, and finally rotates the operating ring 4 to block the through hole 31, thereby enabling the operating ring 4 to restrict the separation of the elastic block 2 and the limiting ring 3.

[0039] Reference Figure 4 Multiple positioning blocks 42 are fixedly connected to the inner wall of the operating ring 4, and the multiple positioning blocks 42 are distributed in a circumferential array along the operating ring 4. The multiple positioning blocks 42 have elastic deformation capability, and the positioning blocks 42 can be inserted into the fixing holes 33.

[0040] Reference Figure 4 When the positioning block 42 is inserted into the fixing hole 33, the positioning block 42 drives the fixing block 331 to move within the fixing hole 33, causing the fixing strip 332 to deform in the direction of the wire, and the stop protrusion 351 is inserted into the stop groove 232, so that the stop strip 35 drives the elastic strip 23 to deform in the direction of the wire.

[0041] The implementation principle of a metering box coupler in this application embodiment is as follows: by rotating the operating ring 4, the positioning block 42 drives the fixing strip 332 to move, so that the fixing strip 332 squeezes the wire, and the stop protrusion 351 is inserted into the stop groove 232, so that the fixing strip drives the elastic strip 23 to squeeze the wire, thereby reducing the possibility of moisture entering the coupler along the outer surface of the wire.

[0042] A coupler integration method includes the following steps: Install the elastic block 2 on the housing 1, and pass the wire through the through hole 21 into the mounting hole 11; Pull the limiting ring 3 open from the through hole 31, and then place the elastic block 2 inside the limiting ring 3 to complete the assembly of the limiting ring 3 and the elastic block 2; Rotate the operating ring 4 so that the positioning block 42 is located in the fixing hole 33, so that the fixing strip 332 abuts against the wire, and the stop strip 35 causes the elastic strip 23 to deform in the direction of the wire.
