Description

Technical Field

[0001] This utility model relates to the field of cable safety connection technology, specifically a new type of cable that can avoid short circuits at the connection terminals. Background Technology

[0002] A cable is an electrical or signal transmission device, typically consisting of several or groups of conductors. It is made up of one or more mutually insulated conductors and an outer insulating protective layer, and is capable of transmitting electricity or information from one place to another.

[0003] To ensure smooth wiring modifications without power interruption, a new type of cable has been developed (see patent number: 201220324640.4), belonging to the field of cable equipment manufacturing technology. Due to its special design, when cables of multiple electrical appliances or cables themselves are tangled, the new cable can be broken in the middle, making it easier to untangle multiple strands and solve the cable tangling problem. In special circumstances requiring the movement of electrical equipment across obstacles, this new cable can also ensure smooth wiring modifications without power interruption.

[0004] However, when existing cables are spliced, they are usually directly electrically connected to the connection end after splicing. If the power is turned on directly, it will cause a short circuit at the connection end, which will directly affect the equipment connected to the cable and affect its normal operation. This increases the difficulty of splicing safety to a certain extent and reduces the utilization rate. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of cable that can avoid short circuits at the connection terminals, in order to solve the problem of short circuits caused by incorrect connection at the connection terminals and the safety hazards of connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel cable that can avoid short circuits at the docking terminals, comprising a connecting frame, wherein a rotating frame is provided at the middle position of one end of the connecting frame, and a connecting wire is snapped into the interior of the rotating frame;

[0007] The connector has card holders on both sides of one end, and the first wire and the second wire are respectively clamped inside the card holders. Magnetic blocks are embedded on one side of the top of one end and one side of the bottom of the card holder. Iron blocks matching the magnetic blocks are embedded on one side of the top of the connecting wire and one side of its bottom.

[0008] As a further improvement of this utility model: one end of the rotating frame is provided with a slot, and both the card holder and the slot are provided with notches at the ends away from the connecting frame, and the interiors of the card holder and the slot are formed into arc-shaped grooves through the notches.

[0009] As a further improvement of this utility model, the connecting wire is magnetically connected to the connecting frame through the mutual cooperation of the magnetic block and the iron block.

[0010] As a further embodiment of this utility model: both the first conductor and the second conductor are provided with a docking terminal on the side near the connecting conductor, and the first conductor, the second conductor, and the connecting conductor are all electrically connected through the docking terminal.

[0011] As a further improvement of this utility model: a rotating shaft is provided at the middle position of the rotating frame near the connecting frame, and the rotating frame is rotatably connected to the connecting frame through the rotating shaft.

[0012] As a further improvement of this utility model: the first wire, the second wire, and the connecting wire are all connected to the card holder and the card slot respectively through notches.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting the connection wire on the cable to disconnect from the first and second wires on both sides, the two ends of the cable itself are effectively connected and corresponding connection equipment is used. At the same time, by using the disconnection position of the connection wire from the first and second wires, the cable can be directly short-circuited by an external short-circuit detector, thereby effectively avoiding a series of equipment damage problems caused by short circuits due to direct connection.

[0015] 2. The magnetic blocks and iron blocks enhance the stability between the connecting wire and the connecting frame, while ensuring effective electrical connection between both sides of the connecting wire and the first and second wires, thus guaranteeing the stability of the cable.

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.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figures 1-3 In this embodiment of the utility model, a novel cable that can avoid short circuits at the docking terminals includes a connecting frame 1, a rotating frame 2 is provided at the middle position of one end of the connecting frame 1, and a connecting wire 3 is snapped into the inside of the rotating frame 2.

[0023] The connecting frame 1 has card holders 101 on both sides of one end. The card holders 101 are respectively connected to the first wire 103 and the second wire 105. The card holders 101 have magnetic blocks 102 embedded on one side of the top and one side of the bottom. The connecting wire 3 has iron blocks 301 that match the magnetic blocks 102 embedded on one side of the top and one side of the bottom.

[0024] In this embodiment, a magnetic block refers to a magnetic object capable of attracting metals such as iron, cobalt, and nickel. Magnetic blocks are typically composed of atoms of iron, cobalt, and nickel. These atoms have a unique internal structure, possess magnetic moments, and can generate a magnetic field. Magnetic blocks can be categorized into permanent magnets and electromagnets. Permanent magnets include natural or artificial magnets, while electromagnets require an external current to generate a magnetic field. An iron block refers to an object made of iron that is not magnetic itself. An iron block can be attracted by a magnetic block, but it will not generate a magnetic field like a magnetic block.

[0025] As a further embodiment of this utility model: a slot is provided at one end of the rotating frame 2, and notches are provided at the ends of the card holder 101 and the slot away from the connecting frame 1. The interiors of the card holder 101 and the slot are formed into arc-shaped grooves through the notches. The first wire 103, the second wire 105, and the connecting wire 3 are respectively connected to the card holder 101 and the slot through the notches. By utilizing the card holder 101 and the slot that form arc-shaped grooves, the first wire 103, the second wire 105, and the connecting wire 3 can be better inserted into the interiors of the rotating frame 2 and the card holder 101 through the notches, thereby improving the snapping effect and facilitating operation. At the same time, during the insertion process, the notches will exert extrusion pressure on the insulation layer outside the first wire 103, the second wire 105, and the connecting wire 3, causing them to deform under pressure. When they are inserted into the interiors of the rotating frame 2 and the card holder 101, the insulation layer can be used to elastically fill the gaps in the connection.

[0026] Please see Figures 1 to 3 The connecting wire 3 is magnetically connected to the connecting frame 1 through the mutual cooperation of the magnetic block 102 and the iron block 301.

[0027] Please see Figures 1 to 3 The first conductor 103 and the second conductor 105 are each provided with a docking terminal 104 on the side near the connecting conductor 3. The first conductor 103, the second conductor 105 and the connecting conductor 3 are all electrically connected through the docking terminal 104.

[0028] Please see Figures 1 to 3 The rotating frame 2 is provided with a rotating shaft at the middle position of one end near the connecting frame 1. The rotating frame 2 is rotatably connected to the connecting frame 1 through the rotating shaft. The rotating shaft makes its rotation easier and reduces the frictional resistance generated during rotation.

[0029] The working principle of this utility model is as follows: When it is necessary to connect cables, the connecting frame 1 can be rotated with the rotating shaft as the base point. While the connecting frame 1 is rotating with the rotating shaft as the base point, the connecting wire 3 with its end face is rotated, and the iron block 301 on the connecting wire 3 is disconnected from the magnetic block 102 on the connecting frame 1. Then, it can be directly rotated counterclockwise by 10°, so that the electrical connection between the docking terminal 104 on the first wire 103 and the second wire 105 and the connecting wire 3 can be directly disconnected.

[0030] After the electrical connection between the connecting wire 3 on the cable and the first wire 103 and the second wire 105 on both sides is disconnected, the two ends of the cable itself are effectively connected and corresponding connection equipment is used. At the same time, by using the disconnection position between the connecting wire 3 and the first wire 103 and the second wire 105, the cable can be directly short-circuited by an external short-circuit detector, which can effectively avoid a series of equipment damage problems caused by short circuits due to direct connection.

[0031] After the test is completed, the rotating frame 2 can be turned clockwise to rotate the connecting wire 3 around the rotating shaft. This causes the two sides of the connecting wire 3 to contact and electrically connect with the docking terminals 104 on the first wire 103 and the second wire 105, respectively. At the same time, the iron block 301 located on the end face of the connecting wire 3 is magnetically connected to the magnetic block 102 embedded on the connecting frame 1. Thus, the series connection and electrical connection between the first wire 103, the second wire 105 and the connecting wire 3 can be realized.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
