Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, and in particular to an anti-detachment cable connector for power systems. Background Technology

[0002] In power systems, cable connectors are common electrical components used to lock and secure incoming and outgoing lines, connecting laid cable sections into a single unit.

[0003] Existing cable connectors typically consist of a plug and a socket. In use, the plug is usually inserted directly into the socket. Although the plug and socket can fit together stably, they are prone to detachment due to misoperation or accidental pulling. For cable connectors used in equipment that needs to be moved frequently, there is more dragging, which can easily cause the cable connector to loosen and affect the normal use of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-derailment cable connector for power systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cable connector for use in a power system with anti-derailment features includes a first connector and a trapezoidal block. The first connector has a connection compartment at its top, and a trapezoidal block is fixedly connected to the inner wall of the top of the connection compartment. A cable is connected to the bottom of the first connector. It also includes a second connector, the bottom outer ring of which is evenly provided with four arc-shaped grooves, and an anti-detachment mechanism including an arc-shaped slider and an annular rotating block is slidably arranged in the arc-shaped grooves; An arc-shaped slider is slidably connected inside the arc-shaped groove. An annular rotating block is fixedly connected to the bottom of the four arc-shaped sliders. A trapezoidal groove is opened at the bottom of the outer wall of the annular rotating block, and a sinking groove is opened on one side of the top of the trapezoidal groove.

[0006] Preferably, the bottom of the connecting compartment is fixedly connected to four connecting ends, each with a different specification.

[0007] Preferably, three rectangular blocks are fixedly connected to the inner wall of the top of the connecting compartment, and the three rectangular blocks and one trapezoidal block are evenly distributed among each other.

[0008] Preferably, a connecting block is fixedly connected to the bottom of the second connector, the connecting block is adapted to the connecting chamber, and the outer wall of the connecting block is movably connected to the inner wall of the annular rotating block.

[0009] Preferably, the bottom of the connecting block has four connecting ends, which are respectively adapted to four connecting end heads.

[0010] Preferably, a toggle block is fixedly connected to the top outer wall of the annular rotating block, and the toggle block has a toothed groove on its outer ring.

[0011] Preferably, the bottom of the outer wall of the annular rotating block is provided with three rectangular grooves, and the three rectangular grooves and one trapezoidal groove are respectively adapted to the three rectangular blocks and one trapezoidal block. A sunken groove is provided on one side of the top of each of the three rectangular grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting an anti-detachment mechanism, ensures that when the cable is dragged by an external force after the first connector and the second connector are connected through the anti-detachment mechanism, each sinking groove can effectively block the rectangular block and trapezoidal block, preventing the first connector and the second connector from falling off. This effectively prevents the equipment from malfunctioning due to cable loosening during frequent equipment movement.

[0013] This invention uses trapezoidal blocks, which have different shapes than rectangular blocks. Correspondingly, the trapezoidal grooves and rectangular grooves have different shapes. Before connecting the first and second connectors, the trapezoidal blocks and grooves only need to be aligned to simultaneously align the three rectangular blocks and three rectangular grooves. This facilitates the one-to-one correspondence between the connectors of different specifications and the connectors, preventing damage to the connectors caused by forced connection without alignment.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-6 A cable connector for power systems with anti-detachment features includes a first connector 1 and a trapezoidal block 5. The first connector 1 has a connection compartment 2 at its top, and a trapezoidal block 5 is fixedly connected to the inner wall of the top of the connection compartment 2. A cable is connected to the bottom of the first connector 1. It also includes a second connector 6, with four arc-shaped grooves 9 evenly distributed on the outer ring of the bottom of the second connector 6. An anti-detachment mechanism 11, including an arc-shaped slider 10 and an annular rotating block 12, is slidably arranged in the arc-shaped grooves 9. Arc-shaped sliders 10 are slidably connected inside the arc-shaped groove 9. An annular rotating block 12 is fixedly connected to the bottom of the four arc-shaped sliders 10. A trapezoidal groove 14 is opened at the bottom of the outer wall of the annular rotating block 12, and a sinking groove 16 is opened on one side of the top of the trapezoidal groove 14. The first connector 1 and the second connector 6 are respectively connected to the cables to be connected at both ends. After the first connector 1 and the second connector 6 are connected by the anti-detachment mechanism 11, when the cable is dragged by an external force, each sinking groove 16 can effectively block the rectangular block 4 and the trapezoidal block 5, so that the first connector 1 and the second connector 6 cannot fall off. This can effectively prevent the equipment from malfunctioning due to cable loosening during frequent equipment movement. Since the trapezoidal block 5 has a different shape than the rectangular block 4, the corresponding trapezoidal groove 14 and rectangular groove 15 have different shapes. Before connecting the first connector 1 and the second connector 6, it is only necessary to align the trapezoidal block 5 and the trapezoidal groove 14 so that the three rectangular blocks 4 and the three rectangular grooves 15 can be aligned at the same time. This makes it easy to match each connector end 3 of different specifications with the connector end 8 one by one, preventing forced connection without alignment and damage to the connector end 3.

[0018] As a technical optimization of this utility model, four connection terminals 3 are fixedly connected to the bottom of the connection compartment 2, and each connection terminal 3 has different specifications. The diameter, contact position, etc. of each connection terminal 3 are different, so they need to correspond one-to-one with the connection terminal 8 in order to facilitate the effective connection of the cable and the normal operation of the equipment.

[0019] As a technical optimization of this utility model, three rectangular blocks 4 are fixedly connected to the inner wall of the top of the connecting compartment 2. The three rectangular blocks 4 and one trapezoidal block 5 are evenly distributed. The three rectangular blocks 4 and one trapezoidal block 5 are at the same height in the connecting compartment 2, and the thickness of the three rectangular blocks 4 and one trapezoidal block 5 is also the same. The included angle between them is 90 degrees.

[0020] As a technical optimization of this utility model, a connecting block 7 is fixedly connected to the bottom of the second connector 6. The connecting block 7 is adapted to the connecting chamber 2, and the outer wall of the connecting block 7 is movably connected to the inner wall of the annular rotating block 12. The connecting block 7 and the annular rotating block 12 are rotatable. After the connecting block 7 and the connecting end 8 are respectively connected to the connecting chamber 2 and the connecting end 3, the rotation of the annular rotating block 12 is not affected, that is, the connection of the rectangular block 4 and the trapezoidal block 5 into the sinkhole 16 is not affected.

[0021] As a technical optimization of this utility model, the bottom of the connecting block 7 is provided with four connecting ends 8, which are respectively adapted to four connecting ends 3. The contact points of the four connecting ends 8 and the four connecting ends 3 correspond one-to-one in terms of position and diameter, and are positioned and aligned by the trapezoidal block 5 and the trapezoidal groove 14.

[0022] As a technical optimization of this utility model, a toggle block 13 is fixedly connected to the top outer wall of the annular rotating block 12, and the toggle block 13 has a toothed groove on its outer ring. The toggle block 13 is used to manually rotate the annular rotating block 12.

[0023] As a technical optimization of this utility model, three rectangular grooves 15 are provided on the bottom of the outer wall of the annular rotating block 12. The three rectangular grooves 15 and one trapezoidal groove 14 are respectively adapted to three rectangular blocks 4 and one trapezoidal block 5. A recessed groove 16 is provided on one side of the top of each of the three rectangular grooves 15. The recessed groove 16 is used to hold the three rectangular blocks 4 and one trapezoidal block 5, so that the first connector 1 and the second connector 6 will not fall off when the cable is dragged by external force.

[0024] In use, the two cables to be connected are first fixedly connected to the first connector 1 and the second connector 6 respectively. Then, the positions of the trapezoidal block 5 and the trapezoidal groove 14 are checked. The trapezoidal block 5 is aligned with the trapezoidal groove 14. Since the relative positions of the trapezoidal block 5 and the rectangular block 4, as well as the trapezoidal groove 14 and the rectangular groove 15, are fixed, as long as the trapezoidal block 5 is aligned with the trapezoidal groove 14, the three rectangular blocks 4 can be aligned with the three rectangular grooves 15. At the same time, the connecting end 8 and the connecting head 3 can also correspond one-to-one. At this time, the first connector 1 and the second connector 6 are pushed respectively, so that the annular rotating block 12 is inserted into the connecting compartment 2, and the connecting block 7 is connected to the first connector 1 and the second connector 6. When the cable is inserted into the connection compartment 2, as the push continues, each connection end 3 is inserted into the connection end 8, while the rectangular block 4 and the trapezoidal block 5 slide into the rectangular groove 15 and the trapezoidal groove 14 respectively. When the trapezoidal block 5 slides to the top of the trapezoidal groove 14, the ring rotating block 12 is rotated along the arc-shaped slide groove 9 by manually rotating the toggle block 13 counterclockwise, so that the trapezoidal block 5 and the rectangular block 4 slide relative to each sinking groove 16, and the connection is completed. When the cable is dragged, the first connection head 1 and the second connection head 6 block the trapezoidal block 5 and the rectangular block 4 through the sinking groove 16 so that the first connection head 1 and the second connection head 6 will not fall off.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
