Problems solved by technology

[0003] Since the conductive connectors of the existing connectors are all exposed, this structure leads to the operation of the existing connectors must be carried out in a power-free state. When the line fails, it is reasonable to cut off the power for maintenance.

Embodiment approach 1

[0027] Implementation Mode 1: For detailed structure, see Figure 4 . This is a wall bushing used for thin walls, and it is also used indoors, such as electrical cabinets and cable branch boxes. The walls are actually steel plates.

[0028] From Figure 4 It can be seen that the present invention has a conductive connecting body 1, an insulator 2, and a mounting part 4, and the connectors at both ends of the conductive connecting body 1 are internally threaded connectors, and the internally threaded joints at both ends are through. The installation part 4 is fixed on the insulator 2 or the installation part 4 is integrated with the insulator 2, and the installation part 4 is used for fixing the wall-through pipe sleeve on the wall. The insulator 2 is firmly attached to the outside of the conductive connecting body 1, but its length is longer than that of the conductive connecting body 1, so that the conductive connecting body 1 is hidden in the insulator 2, and the long part...

Embodiment approach 2

[0031] Embodiment 2: This is a wall-piercing casing for outdoor use.

[0032] From Figure 5 It can be seen that the conductive connecting body 1 of this embodiment adopts a solid round steel structure, with screw holes at both ends, the length of the insulator 2 exceeds the outer ends of the screw holes, and the protruding parts of the insulator 2 are respectively formed at the outer ends of the two screw holes. One end interrupter 5. This structure makes the wall pipe sleeve have sufficient length and strength to adapt to its outdoor working conditions. The insulator is made of synthetic insulating material, and its skirt is used to prevent water accumulation.

Embodiment approach 3

[0033] Embodiment 3: This is a wall-piercing sleeve, which has advantages in length and strength, and is very suitable for extra-thick walls.

[0034] From Figure 6 It can be seen that in this embodiment, compared with the embodiment, the connectors at both ends of the conductive connecting body 1 are externally threaded connectors 12, and there is enough space between the insulator 2 and the externally threaded connector 12 to allow the external connectors to be inserted and form Side arc extinguishing chamber 6. In order to further improve the arc extinguishing effect, the length of the insulator 2 exceeds the end face of the externally threaded connector to form an end arc extinguishing chamber 5 .

[0035] This embodiment is suitable for the connected power line terminal is a screw hole interface, and the length of the conductive connecting body 1 can be arbitrarily selected according to the thickness of the wall.

Abstract

The invention discloses a connecting member and a combined connector thereof. The connecting member comprises a conductive connector and an insulator, joints of two ends of the conductive connector are of threaded connection structures, the length of the insulator covering the conductive connector is at least longer than the end face of the conductive connector so as to hide the conductive connector in the insulator, and workers are prevented from contacting with the conductive connector during mounting or maintenance. The connecting member can work with electricity and is simple to operate, and two or more than two connecting members are combined to form a plurality of combined connectors. The two connecting members are arranged in two insulated closed arc extinction chambers when abutted before contacting with the conductor, and are very safe.

Description

technical field [0001] The invention relates to a connecting piece for electric equipment. Background technique [0002] The connection point between two devices or between two power lines is faulty due to excessive load or high resistance of the connection point during operation, resulting in heat generation, and has to be powered off for maintenance. A power outage maintenance at one point will lead to a power outage in an area, which will not only bring losses to the power department, but more importantly, it will bring losses to users. This phenomenon has long been considered normal and objective, and understandable. Let's take a look at the structure of the existing power equipment connectors, see Figure 1-Figure 3 . figure 1 It is the most common connection between two devices or two power lines. When in use, two wires to be connected are respectively crimped with one end of the connector, and the other end is threaded and tightened with a bolt. It is obvious ...
