Abstract
Description
Technical Field
[0001] This application relates to the field of pipe fitting technology, and in particular to an equipotential internal threaded fitting. Background Technology
[0002] In the field of hydroelectric construction, equipotential bonding couplings play a crucial role in ensuring the safe use of hydroelectric appliances. This technology achieves potential balance by connecting the equipotential bonding coupling to the equipotential terminal box using a conductor, thereby effectively preventing electric shock injuries caused by potential differences exceeding safe limits. This emphasizes the paramount importance of conductivity between the equipotential bonding coupling and the equipotential terminal box.
[0003] Currently available equipotential bonding wire connectors on the market generally use a side-connection method for the wire, with a locking screw on the front to secure it. However, this connection method reveals a significant problem during actual installation: when on-site masons are laying tiles or drilling holes, careless operation can easily cause the wire to be compressed or even broken at the connector, leading to connection detachment and rendering the designed safety protection function ineffective, seriously threatening the user's personal safety. Furthermore, such problems often lead to rework in subsequent projects, increasing unnecessary reconnection costs and time.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] This application provides an equipotential internal thread connector, which can solve the problems of existing equipotential internal thread connectors that easily lead to wire damage and detachment, failure of safety protection, and increased rework costs.
[0007] (II) Technical Solution
[0008] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0009] An equipotential internal thread connector is provided, the equipotential internal thread connector comprising:
[0010] Pipe fittings, conductive connectors, wires, and locking devices;
[0011] The water pipe joint is provided with a pipe and an interface communicating with the pipe;
[0012] The conductive connector is fixedly installed inside the interface and has a connection port. The conductive connector has a wire hole extending in a direction away from the connection port and a locking hole extending from the wire hole to the side of the conductive connector.
[0013] The wire is electrically connected to the conductive connector and passes through the wire hole;
[0014] The locking element is connected to the inside of the locking hole and presses the wire against the inside of the wire hole.
[0015] In some embodiments, one end of the conductive connector extends from the interface to form an exposed portion, and the locking hole extends radially from the wire hole to the side of the exposed portion.
[0016] In some embodiments, the locking hole is a threaded hole, and the locking element is a locking screw that matches the threaded hole. The locking screw is screwed into the locking hole and secures the wire in the wire hole.
[0017] In some embodiments, the equipotential internal thread connector further includes a voltage-conducting piece, one end of which is fixedly connected to the conductive connector, and the other end extends into the interior of the wire hole along a direction inclined to the guide hole; the end face of the conductive connector is provided with the locking hole and extends along the length direction of the wire hole, one end of the locking member extends into the wire hole and abuts against the voltage-conducting piece, so that the voltage-conducting piece elastically deforms and presses the wire against the inside of the wire hole.
[0018] In some embodiments, the wire hole extends along the length of the conductive connector.

[0024] First, it protects the wires from damage: the wires are laid to the rear end of the conductive connector and water pipe connector through the wire hole built into the conductive connector, and are fixed on the side with locking devices. This effectively avoids the risk of the wires being damaged by pressure during the laying of perforated tiles, thereby extending the service life of the wires.
[0025] Equally important is the enhanced stability of electrical connections: the inwardly laid wires, combined with the locking mechanism, ensure a secure connection between the wires and the conductive connectors, avoiding instability caused by wire damage, improving product reliability, reducing safety hazards caused by electrical faults, and providing users with a safer operating environment.

Detailed Implementation
[0037] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0038] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0039] See Figure 1 As shown, Figure 1 This is a schematic diagram of an existing equipotential bonding threaded connector. Existing equipotential bonding threaded connectors generally use a side-connector for the wire, with the wire secured by a screw on the front. However, this connection method reveals a significant problem during actual installation: when on-site tile setters are laying tiles or drilling holes, careless operation can easily cause the wire to be compressed or even broken at the connector, leading to connection detachment and rendering the designed safety protection function ineffective, seriously threatening the user's personal safety. Furthermore, such problems often lead to rework in subsequent projects, increasing unnecessary reconnection costs and time.
[0040] To address the aforementioned technical problems, this embodiment provides an equipotential internal thread connector. (See reference...) Figures 2 to 4 As shown, Figure 2 This is a schematic diagram of the equipotential internal thread connector in an embodiment of this application. Figure 3 This is a schematic diagram of the conductor of the equipotential internal thread connector leading out from the end face in an embodiment of this application. Figure 4 This is a schematic diagram of the wires of the equipotential internal thread connector being led out from the side in an embodiment of this application.
[0041] The equipotential internal threaded connector includes: a water pipe connector 1, a conductive connector 2, a wire 3, and a locking element 4.
[0042] The water pipe connector 1 is provided with a pipe 11 and an interface 12 connected to the pipe 11. The pipe 11 is used to deliver water, and the interface 12 is used to install the conductive connector 2.
[0043] The conductive connector 2 is fixedly installed inside the interface 12, such as by injection molding or bonding. The conductive connector 2 has a connection port 21 for connecting to other components. Inside the conductive connector 2, there is a wire hole 22 extending away from the connection port 21, for laying wires 3. The conductive connector 2 also has a locking hole 23 extending from the wire hole 22 to the side of the conductive connector 2, for installing a locking element 4. It is understood that the conductive connector 2 has conductive properties and uses conductive materials such as copper or copper alloys.
[0044] The wire 3 is electrically connected to the conductive connector 2 and passes through the wire hole 22. The wire 3 is used to connect to an external equipotential control device.
[0045] The locking member 4 is connected to the inside of the locking hole 23 and presses the wire 3 against the inside of the wire hole 22, thereby fixing the wire 3 and electrically connecting the wire 3 to the conductive connector 2.
[0046] For example, the equipotential internal thread connector also includes a voltage-conducting tab 6, see [reference]. Figure 5 As shown, Figure 5 This is a schematic diagram of the locking member being fixed and guided by the conductive sheet in the embodiment of this application. The conductive sheet 6 can be a conductive metal sheet with elastic deformation capability. One end of the conductive sheet 6 is fixedly connected to the conductive connector 2, such as being embedded in the embedding hole of the conductive connector 2, and the other end extends into the interior of the wire hole 22 along the direction inclined to the guide hole 22. The end face of the conductive connector 2 is provided with a locking hole 23, which extends along the length direction of the wire hole 22. One end of the locking member 4 extends into the wire hole 22 along the locking hole 23 and abuts against the conductive sheet 6, so that the conductive sheet 6 elastically deforms and presses the wire 3 against the inside of the wire hole 22.
[0047] In one embodiment of the locking member 4 and the locking hole 23, see [reference] Figure 1 As shown, the locking hole 23 is a threaded hole, and the locking component 4 is a locking screw that matches the threaded hole. The locking screw is screwed into the locking hole 23 and secures the wire 3 in the wire hole 22.
[0048] In another embodiment of the locking member 4 and the locking hole 23, see [reference needed]. Figure 1 As shown, the locking element 4 is a pin and is tightly connected to the locking hole 23, thereby tightening the wire 3.
[0049] For example, see Figure 1 As shown, the wire hole 22 extends along the length of the conductive connector 2, which reduces the manufacturing difficulty of the wire hole 22 and improves the convenience of laying the wire 3.
[0050] See Figure 2 and Figure 3 As shown, in order to facilitate the lead-out of the wire 3, the water pipe connector 1 is provided with an external connection hole 13 that communicates with the wire hole 22, and the wire 3 extends to the outside of the water pipe connector 1 through the external connection hole 13.
[0051] Furthermore, the external connection hole 13 extends to the side or end face of the pipe 11, thereby leading the wire 3 out from the side or end face of the pipe 11.
[0052] In some implementations, see Figure 1 As shown, the inner side of the connection port 21 is provided with an internal thread 211.
[0053] In summary, the equipotential internal threaded connector of this application lays the wire 3 to the rear end of the conductive connector 2 and the water pipe connector 1 through the wire hole 22 of the conductive connector 2, and fixes the wire 3 on the side with the locking member 4. Compared with the traditional structure where the wire 3 is led out from the side of the water pipe connector 1, it has the following advantages: First, it protects the wire 3 from damage: by laying the wire 3 to the rear end of the conductive connector 2 and the water pipe connector 1 through the wire hole 22 built into the conductive connector 2, and fixing it on the side with the locking member 4, it effectively avoids the risk of the wire 3 being damaged by pressure during the laying of the perforated tile 5, thereby extending the service life of the wire 3. Second, it enhances the stability of the electrical connection: the inwardly laid wire 3, combined with the locking effect of the locking member 4, ensures a stable connection between the wire 3 and the conductive connector 2, avoiding the problem of unstable electrical connection caused by damage to the wire 3, improving the reliability of the product, reducing the safety hazards caused by electrical faults, and providing users with a safer operating environment.
[0054] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
