Description

Technical Field

[0001] This utility model relates to the field of cable parallelizer technology, specifically to a cable parallelizer. Background Technology

[0002] Cable parallelizers are widely used tools in the electrical field, mainly used for connecting and paralleling wires and cables. Cable parallelizers can be divided into various types according to their functions, structures, materials and applicable scenarios. Manual parallelizers require manual operation, connecting wires or cables together by manual rotation, crimping and other methods. Terminal blocks have the characteristics of quick connection and disconnection, and the connection is usually achieved by snap-fit, plug-in and other methods.

[0003] The above-mentioned cable paralleling method is prone to loosening and falling off in the environment of vibration or impact. The wires loosening or falling off the terminal will cause the circuit to be interrupted, affecting the normal operation of the equipment. Some terminal connections are exposed and do not have waterproof function. When used in water vapor, humid or outdoor environments, moisture can easily penetrate into the wiring, which can lead to circuit failure or corrosion of the terminal. Utility Model Content

[0004] This utility model addresses the problem that wires are prone to loosening and falling off from the terminals under vibration or impact conditions, and that some terminals are exposed and lack waterproofing. It provides a cable paralleling device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a cable paralleling device, including a T-shaped housing, wherein the T-shaped housing is symmetrically provided with inlet channels, and both sides of the T-shaped housing are provided with inlet holes communicating with the inlet channels. The bottom of the T-shaped housing is provided with cable routing holes communicating with the inlet channels. The T-shaped housing is provided with a cover below the cable routing holes. The cover is fixedly connected to the T-shaped housing by screws. Both sides of the T-shaped housing are provided with fastening mechanisms for winding and fixing the wires. The bottom of the T-shaped housing is provided with a paralleling mechanism for electrically connecting and fixing the wires.

[0006] As an improvement, a sealing ring is provided under the cover.

[0007] As an improvement, the fastening mechanism includes a stud rotatably connected to the upper side of the T-shaped housing, the stud extending above the T-shaped housing, a bottom sleeve provided on the T-shaped housing and below the stud, the bottom sleeve extending below the T-shaped housing, the stud being threadedly connected to the bottom sleeve, and a wire-passing hole provided in the middle of the stud.

[0008] As an improvement, the paralleling mechanism includes two fastening bolts threadedly connected to the T-shaped housing. The lower end of the fastening bolts is rotatably provided with a pressure plate. A through groove is provided inside the T-shaped housing and between the pressure plates. The pressure plate is slidably connected to the T-shaped housing. An extension groove is provided on the top of the T-shaped housing, and the fastening bolts are located in the extension groove.

[0009] As an improvement, the bottom of the pressure plate is an inwardly concave arc-shaped surface, and the pressure plates are electrically connected by wires, which are curved and located in a through groove.

[0010] The advantages of this utility model are: 1. Improves the connection stability of the conductor during the paralleling process. The stud of the fastening mechanism pre-wraps and presses the conductor before paralleling, so that the conductor has good connection stability in the environment of vibration or impact.

[0011] 2. Improve the protection effect at the parallel connection point. On the one hand, the parallel connection point is located at the bottom of the inlet channel. After the T-shaped housing seals the inlet hole, it can effectively prevent the parallel connection mechanism from contacting the outside. On the other hand, the sealing of the cable routing hole by the cover with the sealing ring can prevent dust particles from entering the cable routing hole and causing a short circuit.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-4A cable paralleling device includes a T-shaped housing 1, with symmetrically arranged inlet channels 2 inside the T-shaped housing 1. Inlet holes 3 communicating with the inlet channels 2 are provided on both sides of the T-shaped housing 1. Cable routing holes 4 communicating with the inlet channels 2 are provided on the bottom of the T-shaped housing 1. A cover 5 is provided below the cable routing holes 4 on the T-shaped housing 1, and a sealing ring 6 is provided below the cover 5. The sealing ring 6 prevents dust particles from entering the cable routing holes 4 and causing a short circuit. The cover 5 is fixedly connected to the T-shaped housing 1 by screws. Fastening mechanisms for winding and fixing conductors 14 are provided on both sides of the T-shaped housing 1. The fastening mechanisms can pre-fix single-strand or double-strand conductors 14 to prevent the cable from detaching at the joint due to stretching, thus improving the tightness of the connection at the joint. The fastening mechanism includes a stud 7 rotatably connected to the upper side of the T-shaped housing 1, extending above the T-shaped housing 1. A bottom sleeve 8 is provided on the T-shaped housing 1 below the stud 7. Extending to the bottom of the T-shaped housing 1, the stud 7 is threadedly connected to the bottom sleeve 8, and the stud 7 has a wire hole 9 in the middle; the lower side of the T-shaped housing 1 is provided with a paralleling mechanism for electrically connecting and fixing the wire 14. The paralleling mechanism can parallel multiple wires 14 of different diameters. Based on the fixing of the fastening mechanism, the paralleling mechanism only needs to press the wire 14 together, reducing the fixing pressure requirement of the wire 14 paralleling point and reducing the difficulty of wiring operation. The paralleling mechanism includes two fastening bolts 10 threadedly connected to the T-shaped housing 1. The lower end of the fastening bolts 10 is provided with a pressure plate 11. A through groove 12 is provided inside the T-shaped housing 1 and between the pressure plates 11. The pressure plates 11 are slidably connected to the T-shaped housing 1. An extension groove 13 is provided on the top of the T-shaped housing 1. The fastening bolts 10 are located in the extension groove 13. The bottom of the pressure plate 11 is an inwardly concave arc surface. The pressure plates 11 are electrically connected through the wire 14. The wire 14 is curved and located in the through groove 12.

[0019] In a specific implementation case, the exposed wires 14 are inserted into the wire holes 9 on the studs 7 through the inlet holes 3 on both sides of the T-shaped housing 1, and then advanced along the inlet channel 2 to exit through the cable routing hole 4. The wires 14 need to have extra length after passing through the cable routing hole 4. The studs 7 are rotated one by one so that the wires 14 are wrapped around the studs 7 and pressed under the T-shaped housing 1 by the wire routing hole 9. The fastening bolts 10 are rotated until the pressure plate 11 presses the wires 14 tightly. The excess cable outside the cable routing hole 4 is cut off. The cover 5 is attached to the T-shaped housing 1 and fixed with screws to complete the cable connection operation.

[0020] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
