Description

Technical Field

[0001] This utility model relates to the field of cable wiring technology, and in particular to a cable wiring device for power relocation. Background Technology

[0002] Cable wiring refers to the technical process of reliably connecting cable conductors through specific techniques to ensure the continuity and safety of power transmission. During power relocation, in order to adapt to different laying environments, it is usually necessary to adjust the direction or length of the cable, thereby extending the power line or changing the direction of transportation. By wiring the cable, the safe and stable operation of the line after relocation is ensured.

[0003] Currently, when connecting cables, most methods involve directly twisting the copper coils of two cables together and then using insulating tape to wrap and fix the exposed and twisted copper coils to ensure the stability of the connection. However, after the cable is connected, the insulating tape is prone to aging due to the influence of the external environment, which reduces the adhesion of the insulating tape and causes it to loosen, thus reducing the stability of the cable connection.

[0004] Therefore, regarding the problem that using insulating tape to wrap and fix exposed copper coils can lead to reduced adhesion as the tape ages, causing it to loosen and reducing the stability of the cable connection, a stable connection structure can be set up to compress and fix the cables inside the device, ensuring the stability of the cable connection. Furthermore, by rotating the locking structure, the cables at the connection points on the outside of the device can be clamped to prevent external environmental factors from affecting the cables and causing them to fall off. Utility Model Content

[0005] To overcome the problem that when connecting cables, most people simply twist the copper coils of two cables together and then use insulating tape to wrap and fix the exposed and twisted copper coils to ensure the stability of the connection, the wrapped connection is prone to the problem that the insulating tape will age after being affected by the external environment, resulting in reduced adhesion of the insulating tape, which will cause the insulating tape to loosen and reduce the stability of the cable connection.

[0006] The technical solution of this utility model is as follows: a wiring device for power relocation cables, including a junction box, an inlet hole on the side of the junction box, a threaded connector fixedly connected to the side of the junction box, a collar on the outer side of one end of the threaded connector, a slot on the other end of the threaded connector, an insulating base fixedly connected to the bottom of the inner wall of the junction box, a guide groove on the top surface of the insulating base, and a sealing gasket on the top surface of the junction box.

[0007] Preferably, the inlet holes are symmetrically distributed on the junction box, the inlet holes are connected to the threaded connector, the collar is tightly attached to the side of the junction box, the slots are distributed at equal angles on the threaded connector, and the guide grooves are symmetrically distributed on the insulating base.

[0008] Preferably, the outer side of the threaded connector is connected to a threaded sleeve by a thread, and the outer side of the threaded sleeve is provided with anti-slip grooves, which are distributed at equal angles on the threaded sleeve. A sealing ring is fixedly connected to the inner wall of the end of the threaded sleeve away from the junction box.

[0009] Preferably, the top surface of the insulating base is fixedly connected to a fixing seat, the top surface of the fixing seat is provided with a fixing clamp, the top surface of the fixing clamp is symmetrically provided with a clamping bolt, and the fixing clamp is threadedly connected and fixed to the fixing seat through the clamping bolt.

[0010] Preferably, a sealing cover is rotatably connected to the top surface of the junction box, and a lock head is welded and fixed to the side of the sealing cover. The lock heads are symmetrically distributed on the sealing cover, and limit holes are formed on the side of the lock heads.

[0011] Preferably, a telescopic rod is fixedly connected to the top of the inner wall of the sealing cover. The telescopic rods are symmetrically distributed on the sealing cover. A compression spring is slidably sleeved on the outer side of the telescopic rod. An arc-shaped pressure plate is fixedly connected to the bottom surface of the telescopic rod. The arc-shaped pressure plate is positioned directly above the guide groove.

[0012] Preferably, a locking box is fixedly connected to the side of the junction box. The locking boxes are symmetrically distributed on the junction box. A locking groove is opened on the top surface of the locking box. The lock head is slidably connected to the locking groove. A limit pin is slidably connected inside the locking box. A limit spring is slidably sleeved on the outside of the limit pin.

[0013] The beneficial effects of this utility model are:

[0014] 1. After the sealing cap is closed, the arc-shaped pressure plate contacts the surface of the cable, pushes the telescopic rod to retract, and compresses the clamping spring. The elastic force of the clamping spring pushes the arc-shaped pressure plate to clamp and fix the cable at the connection point, preventing the cable from shaking and ensuring the stability of the cable connection point.

[0015] 2. After the sealing cover is closed and locked, the threaded sleeve is screwed into the threaded connector by rotation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 and Figure 2This utility model provides an embodiment: a power relocation cable wiring device, including a junction box 1, a wire inlet hole 2 on the side of the junction box 1, a threaded connector 3 fixedly connected to the side of the junction box 1, a collar 4 provided on the outer side of one end of the threaded connector 3, a slot 5 provided on the other end of the threaded connector 3, an insulating base 6 fixedly connected to the bottom of the inner wall of the junction box 1, a guide groove 7 provided on the top surface of the insulating base 6, and a sealing gasket 8 provided on the top surface of the junction box 1.

[0026] Please see Figure 1 and Figure 2 The inlet holes 2 are symmetrically distributed on the junction box 1 and are connected to the threaded connector 3. The collar 4 is tightly attached to the side of the junction box 1. The slots 5 are evenly distributed on the threaded connector 3. The guide grooves 7 are symmetrically distributed on the insulating base 6. The collar 4 can ensure the sealing of the connection between the threaded connector 3 and the junction box 1. The cable can be inserted into the guide groove 7 for limited movement through the inlet holes 2. The sealing gasket 8 can ensure the sealing between the junction box 1 and the sealing cover 801 and increase the waterproof effect of the device.

[0027] Please see Figure 1 and Figure 4 A threaded sleeve 301 is threadedly connected to the outer side of the threaded connector 3. An anti-slip groove 302 is provided on the outer side of the threaded sleeve 301. The anti-slip groove 302 is evenly distributed on the threaded sleeve 301. A sealing ring 303 is fixedly connected to the inner wall of the end of the threaded sleeve 301 away from the junction box 1. The anti-slip groove 302 prevents slippage during rotation. When the threaded sleeve 301 is rotated and screwed into the threaded connector 3, the groove 5 is squeezed and shrinks inward during rotation, thereby generating a radial clamping force to clamp and fix the connected cable and prevent the cable from falling off.

[0028] Please see Figure 2 and Figure 3 The top surface of the insulating base 6 is fixedly connected to the fixing seat 601. The top surface of the fixing seat 601 is provided with a fixing clamp 602. The top surface of the fixing clamp 602 is symmetrically provided with a clamping bolt 603. The fixing clamp 602 is threadedly connected and fixed to the fixing seat 601 through the clamping bolt 603. After inserting the two cables into the junction box 1, the two copper coils are wrapped together and placed on the fixing seat 601. The clamping bolt 603 is then tightened to connect and fix the fixing clamp 602 to the fixing seat 601, thus clamping and fixing the wrapped copper coils to ensure the stability of the connection.

[0029] Please see Figure 2 and Figure 5A sealing cover 801 is rotatably connected to the top surface of junction box 1. A lock head 802 is welded and fixed to the side of the sealing cover 801. The lock heads 802 are symmetrically distributed on the sealing cover 801. Limiting holes 803 are opened on the side of the lock head 802. After the copper coil is clamped and fixed, the sealing cover 801 is rotated and engaged with the junction box 1 to prevent the copper coil from being exposed to the external environment, provide protection for the wiring of the internal cable, and ensure the stability of the connection.

[0030] Please see Figure 2 and Figure 5 A telescopic rod 804 is fixedly connected to the top of the inner wall of the sealing cover 801. The telescopic rods 804 are symmetrically distributed on the sealing cover 801. A compression spring 805 is slidably sleeved on the outer side of the telescopic rod 804. An arc-shaped pressure plate 806 is fixedly connected to the bottom surface of the telescopic rod 804. The arc-shaped pressure plate 806 is located directly above the guide groove 7. During the process of closing the sealing cover 801, the arc-shaped pressure plate 806 contacts the surface of the cable, pushes the telescopic rod 804 to retract, and compresses the compression spring 805. After the sealing cover 801 is locked, the elastic force of the compression spring 805 pushes the arc-shaped pressure plate 806 to clamp and fix the cable at the connection point, so as to prevent the cable from shaking.

[0031] Please see Figure 1 , Figure 2 and Figure 6 A locking box 901 is fixedly connected to the side of the junction box 1. The locking boxes 901 are symmetrically distributed on the junction box 1. A locking groove 902 is opened on the top surface of the locking box 901. The lock head 802 is slidably connected to the locking groove 902. A limit pin 903 is slidably connected inside the locking box 901. A limit spring 904 is slidably sleeved on the outside of the limit pin 903. After the sealing cover 801 is closed, the lock head 802 is inserted into the locking groove 902. Due to the arc-shaped bottom of the lock head 802 and the sloping top of the limit pin 903, the limit pin 903 will be pushed outward during the insertion of the lock head 802, compressing the limit spring 904. After the lock head 802 is inserted into place, the limit pin 903 is pushed into the limit hole 803 by the elastic force of the limit spring 904 to limit the movement and prevent the sealing cover 801 from loosening.

[0032] Working principle: According to Figures 1-4 As shown, before connecting the cables, the two sets of cables are inserted into the threaded sleeve 301 through the flared sealing ring 303. The cables are then passed through the threaded connector 3 and the inlet hole 2, allowing the cables to slide on the guide groove 7 into the junction box 1. The copper coils of the two sets of cables are wrapped together on the fixed base 601. The clamping bolt 603 is then tightened, and the fixing clamp 602 is connected and fixed to the fixed base 601, thereby clamping the wrapped copper coils and ensuring the stability of the connection.

[0033] according to Figure 2 and Figure 5 As shown, after the copper coil is clamped and fixed, the sealing cover 801 is rotated and engaged with the junction box 1. During the rotation and closing of the sealing cover 801, the arc-shaped pressure plate 806 contacts the surface of the cable, pushing the telescopic rod 804 to retract and compressing the compression spring 805. After the sealing cover 801 is locked, the elastic force of the compression spring 805 pushes the arc-shaped pressure plate 806 to clamp and fix the cable at the connection point, preventing the cable from shaking. The sealing cover 801 and the junction box 1 provide protection for the connection point of the internal cable, preventing the copper coil from being exposed to the external environment and ensuring the stability of the connection.

[0034] according to Figure 1 , Figure 2 and Figure 6 As shown, during the closing process of the sealing cover 801, the lock head 802 is inserted into the lock groove 902. During the insertion of the lock head 802, the limiting pin 903 will slide outward to compress the limiting spring 904. After the lock head 802 is inserted into place, the limiting pin 903 will be pushed into the limiting hole 803 by the elastic force of the limiting spring 904 to limit the movement and prevent the sealing cover 801 from becoming loose.

[0035] according to Figures 1-4 As shown, after the sealing cover 801 is closed and locked, the threaded sleeve 301 is rotated and screwed into the threaded connector 3. During the rotation, the slot 5 is squeezed and shrinks inward, thereby generating a radial clamping force to clamp and fix the connected cable, preventing the cable from falling off. The sealing ring 303 increases the sealing between the cable and the threaded sleeve 301, and the collar 4 increases the sealing between the threaded connector 3 and the threaded sleeve 301, preventing external moisture from entering the junction box 1 through the inlet hole 2.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
