Description

Technical Field

[0001] This invention relates to the field of cable assembly auxiliary tools, particularly to the field of assembly auxiliary tools for power supply cables in application scenarios, and more specifically to capsule-type cable quick-connect terminals. Background Technology

[0002] In electrical testing, it is often necessary to connect multiple power cables, which leads to the problem of splicing / connection between cables.

[0003] CN111030033A discloses a safe cable splicing device, including a first splicing cylinder and a second splicing cylinder. The surface of the first splicing cylinder is provided with inclined second fastening strips at equal intervals along a ring. A second compression spring is fixedly connected to the bottom right side of the higher end of the second fastening strip, and the bottom of the second compression spring is fixed to the surface of the first splicing cylinder. The bottom of the lower end of the second fastening strip is also fixed to the surface of the first splicing cylinder. This design effectively ensures stable cable splicing during use and guarantees good tensile strength after splicing. It prevents the splicing device from loosening due to external factors after prolonged use, thus avoiding accidents caused by loose splicing and ensuring normal power supply in cities.

[0004] This method requires workers to use tools to wrap the two cables together and then cover them with insulating tape. It also involves initial, secondary, and tertiary connections, making the process very complex. Moreover, this connection method is rather crude.

[0005] CN114361860A discloses an electrical terminal block, specifically including: a female terminal block having a mating cavity female end assembly and a power-connecting sleeve disposed inside the female terminal block; a female terminal block having a mating plug fitting and a central mating magnet disposed inside the mating plug fitting; and a cable bundler having a bundled conduit. By mating the female terminal block and the female terminal block, the device structure can be stably connected, easy to use, and can ensure stable power transmission. The structure is aesthetically pleasing and easy to disassemble; by replacing different female ends of a single female terminal block, power can be supplied to multiple lines. While the cable bundler achieves internal cable mating, this method is still considered a crude mating method.

[0006] Therefore, we need a faster and more convenient connector to enable quick and accurate cable connection / splitting. Summary of the Invention

[0007] The technical problem this invention aims to solve is to provide a new cable splicing / leading method, thereby enabling rapid cable splicing / leading. It can also be applied in laboratories, meeting the needs of splicing various types of power cables.

[0008] To address the aforementioned technical problems, this invention discloses a capsule-type cable quick-connect terminal, comprising a cable inlet housing, a cable outlet housing, and a terminal body. The cable inlet housing and the cable outlet housing are joined to form a capsule-type outer shell of the capsule-type cable quick-connect terminal. The terminal body is housed within a cavity formed by the outer shell. The terminal body includes two or more terminal base plates, each terminal base plate being elongated. The long sides of each terminal base plate are fixed on the same axis, and the terminal base plates divide a cylindrical space centered on this axis into several quick-connect spaces. The terminal body also includes conductive copper busbars and components respectively fixed to the conductive copper busbars. A quick-connect assembly consisting of a pair of connectors at both ends, with a set of quick-connect assemblies fixed within each quick-connect space; the cable inlet housing includes an inlet sealing waterproof ring, an inlet connector with a through hole for cable entry, a waterproof core connecting the inlet sealing waterproof ring and the inlet connector, and a tightening nut disposed on the outside of the waterproof core; the cable outlet housing includes an outlet sealing waterproof ring, an outlet connector with a through hole for cable extension, a waterproof core connecting the outlet sealing waterproof ring and the outlet connector, and a tightening nut disposed on the outside of the waterproof core; a through hole for cable passage may be provided at the central axis of the waterproof core.

[0009] The terminal body is the functional component for cable connection / spinning. This invention, through the ingenious design of the terminal base plate, fully utilizes the cavity formed by the capsule-shaped outer shell, dividing it into multiple independent quick-connect spaces. Simultaneously, the cable inlet and outlet shells are fixed in a capsule-like manner, quickly forming a closed protective space, ensuring the terminal body is within an insulated, waterproof, and safe quick-connect space.

[0010] More preferably, the terminal base plates are evenly spaced, dividing the cylindrical space into several identical quick-connect spaces.

[0011] Since the terminal base plate is fixed along the circumference, setting the terminal base plates at equal intervals can make the quick-connect space obtained by the separation the same, and can make the most efficient use of the cavity.

[0012] For example, with two terminal base plates, they are positioned opposite each other at a 180° angle, thus dividing the cavity into two quick-connect spaces for cables with two inner cores. With three terminal base plates, the spacing between them is 120°, creating three quick-connect spaces for cables with three or two inner cores. With four terminal base plates, the spacing between them is 90°, creating four quick-connect spaces for cables with four, three, or two inner cores. And so on. As long as space permits, quick-connect terminals can be constructed in this way to accommodate cables with up to 8 or even 10 inner cores.

[0013] In a preferred embodiment, the quick-connect assembly further includes a pressure block disposed between adjacent terminal base plates. The bottom of the pressure block is provided with a fixing groove adapted to the conductive copper busbar, and the pressure block fixes the conductive copper busbar to the terminal base plate.

[0014] Compared to other fixing methods, the pressure block method can not only fix the conductive copper busbar, but also build a vertical fixing structure on the base plates of two adjacent terminals, improving the overall stability of the structure.

[0015] More preferably, the pressure block has a fastening screw hole, and a conductive copper busbar fastening screw is provided in the fastening screw hole. The copper busbar fastening screw fixes the conductive copper busbar by the clamping force between the copper busbar and the terminal base plate.

[0016] During use, tightening the fastening screws of the conductive copper busbar continuously increases the clamping force between the fastening screws and the terminal base plate, thereby stabilizing and fixing the conductive copper busbar.

[0017] The connector is mainly composed of a connector clamping block. The connector clamping block is provided with a threaded hole that runs through the top and bottom, and also includes a tightening screw that is adapted to the threaded hole and installed in the threaded hole. The side of the connector clamping block is provided with an inlet core hole, and the bottom of the connector clamping block is provided with a fixing groove adapted to the conductive copper busbar.

[0018] Using a wire tightening screw improves the ease of wiring. Insert the wire core into the inlet hole, then tighten the screw to form a conductive connection between the screw, the wire core, and the conductive copper busbar.

[0019] More preferably, the top of the tightening screw is also provided with a tightening nut. Operating with the tightening nut is not only safer, but also makes operation easier by providing anti-slip textures or a small handle.

[0020] As a preferred technical solution, the front and rear sides of the terminal base plate are curved surfaces.

[0021] As a preferred technical solution, the top surface of the pressure block is an arc surface.

[0022] As a preferred technical solution, the top surface of the wiring clamp is an arc surface.

[0023] In a preferred embodiment, the terminal body fits into the cavity.

[0024] The curved surface design provides a better structural foundation for the terminal body to fit perfectly with the cavity, ensuring overall stability after fitting without affecting disassembly and assembly.

[0025] By adopting the technical solution disclosed in this invention, it is possible to quickly connect / split various types of cables with different inner cores, and the overall structure has good waterproof performance, avoiding safety issues such as connector entanglement.

[0028] Figure 3 This is a perspective view of the terminal body. Detailed Implementation

[0029] To better understand the present invention, we will further elaborate on the present invention below with reference to specific embodiments.

[0030] Example 1

[0031] like Figure 1 The capsule-type quick-connect cable terminal shown includes a cable inlet housing 1, a cable outlet housing 2, and a terminal body 3. The cable inlet housing 1 and the cable outlet housing 2 are mated to form the capsule-type outer shell of the capsule-type quick-connect cable terminal; the terminal body 3 is housed within the cavity formed by the outer shell; then combined... Figure 2 The terminal body includes two or more terminal base plates 301, which are elongated strips. In this embodiment, we preferably use curved surfaces on the front and rear sides of the terminal base plate. Figure 2 As can be seen, this embodiment includes four terminal base plates 301, with the long side of each terminal base plate fixed on the same axis. In this embodiment, the four terminal base plates 301 are fixed on axis 302. Figure 2The terminal base plate shown divides the cylindrical space centered on this axis into four quick-connect spaces. It can be seen that in this embodiment, the terminal base plates are preferably spaced equally, with a 90° interval between each base plate, thus dividing the cylindrical space into four identical quick-connect spaces. It also includes a quick-connect assembly consisting of a conductive copper busbar 303 and a pair of terminals 304 fixed to both ends of the conductive copper busbar. Each quick-connect space contains a set of quick-connect assemblies, such as... Figure 2 The diagram shows that quick-connect components are installed in each of the four quick-connect spaces. Then return to... Figure 1 The cable inlet housing includes an inlet sealing waterproof ring 101, an inlet connector 102 with a through hole for cable entry, a waterproof core 103 connecting the inlet sealing waterproof ring and the inlet connector, and a tightening nut 104 disposed on the outside of the waterproof core; the cable outlet housing includes an outlet sealing waterproof ring 201, an outlet connector 202 with a through hole for cable extension, a waterproof core 203 connecting the outlet sealing waterproof ring and the outlet connector, and a tightening nut 204 disposed on the outside of the waterproof core; a through hole 4 for cable passage may be provided at the central axis of the waterproof core.

[0032] The terminal body is the functional main body for cable connection / lead-in. This invention, through the ingenious design of the terminal base plate, fully utilizes the cavity formed by the capsule-shaped outer shell, dividing it into multiple independent quick-connect spaces. Simultaneously, the cable inlet end shell and the cable outlet end shell are fixed in a capsule-like manner, combined with... Figure 1 As can be seen, the cable inlet end housing and the cable outlet end housing can quickly form a closed protective space through the threaded joint 5, ensuring that the terminal body is in an insulated, waterproof, and safe quick-connect space.

[0033] Furthermore, combined Figure 2 and Figure 3 In this preferred embodiment, the quick-connect assembly further includes a pressure block 6, which is disposed between adjacent terminal base plates. The bottom of the pressure block has a fixing groove adapted to the conductive copper busbar, and the pressure block fixes the conductive copper busbar 303 to the terminal base plate. Figure 2 As shown, the pressure block 6 is located in the middle of the conductive copper busbar 303.

[0034] Compared to other fixing methods, the pressure block method can not only fix the conductive copper busbar, but also build a vertical fixing structure on the base plates of two adjacent terminals, improving the overall stability of the structure.

[0035] More preferably, combined with Figure 2 and Figure 3As can be seen, the pressure block 6 has a fastening screw hole 7, and a conductive copper busbar fastening screw 8 is provided in the fastening screw hole 7. The copper busbar fastening screw fixes the conductive copper busbar by the clamping force between it and the terminal base plate.

[0036] During use, tightening the fastening screws of the conductive copper busbar continuously increases the clamping force between the fastening screws and the terminal base plate, thereby stabilizing and fixing the conductive copper busbar.

[0037] Furthermore, in this embodiment, combined with Figure 2 and Figure 3 As can be seen, the connector is mainly composed of a connector clamping block 9. The connector clamping block is provided with a threaded hole that runs through the top and bottom, and also includes a tightening screw 10 that is adapted to the threaded hole and installed in the threaded hole. The side of the connector clamping block is provided with a wire inlet hole 11, and the bottom of the connector clamping block is provided with a fixing groove 12 that is adapted to the conductive copper busbar.

[0038] Using a wire tightening screw improves the ease of wiring. Insert the wire core into the inlet hole, then tighten the screw to form a conductive connection between the screw, the wire core, and the conductive copper busbar.

[0039] More preferably, the top of the tightening screw is further provided with a tightening nut 13. Operating with the tightening nut is not only safer, but also facilitates operation by providing anti-slip textures or a small handle. Figure 2 As shown, the tightening nut 13 is provided with anti-slip texture 1301 and small handle 1302.

[0040] In this embodiment, preferably, combined with Figure 2 and Figure 3 It can be seen that the top surface of the pressure block is curved, and the top surface of the wiring pressure block is also curved. Figure 1 The terminal body is seen to fit perfectly with the cavity.

[0041] The capsule-type cable quick-connect terminal shown in this embodiment can provide quick connections for 1 to 4 core cables.

[0042] In use, first insert the cables to be connected into the through holes of the cable inlet housing 1 and the cable outlet housing 2, respectively. It should be noted that since the cables will form a single cable after connection, the end where the current flows in is considered the inlet, and the end where the current flows out is considered the outlet. At this time, the cable inlet housing 1 and the cable outlet housing 2 are separate. Then, insert the single-core wire from the cable into the inlet core hole 11 of the terminal body, and then tighten the wire core and the conductive copper busbar by operating the wire tightening nut 13 and tightening screw 10 to form a conductive connection. When all four inner cores are connected, the connection is complete.

[0043] After the cable is aligned, first tighten the threaded joint 5, then adjust the cable to make it smooth, and then tighten the clamping nuts at both ends respectively. The clamping nuts squeeze the waterproof core to lock the entire cable, achieving a sealed and secure connection.

[0044] The above describes specific embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
