Description

Technical Field

[0001] This application relates to the field of insulated adapters for power tools, and more particularly to a sleeve insulated adapter. Background Technology

[0002] Various digital wrenches, electric wrenches (commonly known as pneumatic wrenches), and other power tools often require a variety of different sockets to adapt to different application conditions, such as hexagonal sockets and Torx sockets. However, almost all power tools only have one type of drive head. For example, when an electric wrench uses a square-interface drive head, but needs to tighten a hexagonal socket, a socket adapter is required for adaptation.

[0003] The core function of an adapter is interface conversion, allowing for conversion between different shaped interfaces such as round, hexagonal, and square, or between different sized interfaces such as 1 / 2 inch, 1 / 4 inch, 3 / 4 inch, and 3 / 8 inch. This enables wider application compatibility in fields such as power maintenance, new energy vehicle maintenance, mechanical assembly, electronic product manufacturing, aerospace industry, and precision assembly, achieving multi-purpose functionality and extending the service life of various types of sleeves.

[0004] Because sleeve adapters need to withstand significant torque, they require sufficient mechanical strength. Therefore, their raw materials are often high-quality carbon steel or alloy steel (such as 45# steel) with surface hardening treatment, resulting in strong torsional resistance and resistance to deformation. While high-strength metal materials certainly improve the durability and accuracy of the adapter, in applications such as power maintenance and new energy vehicle repair, power cannot be completely cut off for various reasons. Therefore, when using tools to repair these live devices, it is necessary to ensure the electrical insulation performance of the tools to improve safety. This is to prevent damage to the power tools themselves and to ensure the safety of maintenance and operating personnel.

[0005] The most common insulation treatment currently is to only insulate the metal adapter. Although this gives it an external insulation effect, it cannot actually isolate the live equipment from the electronic components inside the power tool, so safety cannot be guaranteed. Utility Model Content

[0006] To address the problem that conventional adapters often fail to guarantee good insulation performance, this application provides a sleeve-insulated adapter.

[0007] The sleeve insulation adapter provided in this application adopts the following technical solution: An insulating adapter for a sleeve includes a female connector for connecting to a power tool and a male connector for connecting to a sleeve. The male and female connectors are provided with insulating connectors, each including a connecting post, a connecting block, and an insulating filler layer. The connecting post is fixedly connected to the end of the male connector near the female connector, and the connecting block is fixedly connected to the end of the female connector near the male connector. A connecting groove is formed at the end of the connecting block opposite to the female connector, and the connecting post is inserted into the connecting groove. The thickness of the connecting groove is greater than the thickness of the connecting post to form a gap. The insulating filler layer fills the gap. The male connector is also covered with a first insulating sheath, and an insulating protective sleeve is provided at the end of the first insulating sheath opposite to the female connector, with the insulating protective sleeve protruding from the male connector.

[0008] Optionally, the connecting column is provided with an anti-detachment protrusion, and the inner wall of the connecting groove is provided with an anti-detachment groove, with the anti-detachment protrusion sinking into the anti-detachment groove.

[0009] Optionally, the connecting block is circumferentially covered with a first insulating inner layer, and the gap between the connecting block and the male connector is filled with a second insulating inner layer. The radial inner side of the second insulating inner layer is connected to the insulating filling layer, and the radial outer side of the second insulating inner layer is connected to the first insulating inner layer.

[0010] Optionally, the connecting block has a through hole that communicates with the connecting groove. An insulating connecting post is filled in the through hole. One end of the insulating connecting post is connected to the insulating filling layer, and the other end of the insulating connecting post is connected to the first insulating inner layer.

[0011] Optionally, the inner wall of the first insulating cover is provided with a first retaining ring in the circumferential direction, and the male head is provided with a first retaining groove in the circumferential direction, and the first retaining ring engages with the first retaining groove.

[0012] Optionally, the female head is covered with a second insulating cover, and a second retaining ring is provided circumferentially at one end of the second insulating cover away from the first insulating cover. A second retaining groove is provided circumferentially on the female head, and the second retaining ring engages with the second retaining groove.

[0013] Optionally, the first insulating cover is provided with a first insulating retaining ring at one end near the second insulating cover, and the second insulating cover is provided with a second insulating retaining ring at one end near the first insulating cover. The first insulating retaining ring is disposed on the insulating connector, and the second insulating retaining ring is disposed on the first insulating retaining ring.

[0014] Optionally, the second insulating cover is provided with a gripping ring in the circumferential direction, and a groove is provided on one end face of the gripping ring, in which a rigid reinforcing ring is snapped and installed.

[0015] Optionally, at least one of the outer walls of the grip ring and the insulating protective sleeve is provided with anti-slip texture.

[0016] In summary, this application includes at least one of the following beneficial technical effects: The male and female connectors are insulated together by an insulating connector. When the male and female connectors are connected to a power tool and a socket respectively, the insulating connector not only ensures an insulated connection between the socket and the power tool, but also ensures smooth torque transmission between the male and female connectors by the specific connection post and connection groove structure. The insulating protective sleeve protruding from the male connector can insulate and isolate the socket connected to the male connector, further improving the insulation performance. The further addition of a first insulating inner layer, a second insulating inner layer, and an insulating connecting post can, on the one hand, further improve the insulation performance between the male and female connectors, and on the other hand, reduce the possibility of deformation and distortion of the insulating filler layer when transmitting torque, so as to better transmit torque.

To further improve the smoothness of torque transmission, two anti-detachment protrusions 34 are protruding from the connecting post 31. Correspondingly, two anti-detachment grooves 35, matching the shape of the anti-detachment protrusions 34, are formed on the inner wall of the connecting groove. The thickness of the connecting groove is greater than the thickness of the connecting post 31 to form a gap between the connecting groove and the connecting post 31, and the insulating filler layer 33 fills the gap. It is understandable that the shape of the connecting post 31 can be straight, cross-shaped, hexagonal, or petal-shaped, and the shape of the connecting groove can be adapted to the shape of the connecting post 31.

[0023] To further improve the insulation performance of the insulating connector 3 and the smoothness of torque transmission between the male connector 1 and the female connector 2, a first insulating inner layer 36 is provided circumferentially to cover the connecting block 32.

A second retaining ring 51 is provided circumferentially at the end of the second insulating cover 5 facing away from the first insulating cover 4, and a second retaining groove 52 is provided circumferentially on the female connector 2, with the second retaining ring 51 engaging with the second retaining groove 52.

[0025] In order to connect the first insulating cover 4 and the second insulating cover 5, a first insulating retaining ring 44 is provided circumferentially at one end of the first insulating cover 4 near the second insulating cover 5, and a second insulating retaining ring 53 is provided circumferentially at one end of the second insulating cover 5 near the first insulating cover 4. The first insulating retaining ring 44 is covered and disposed on the insulating connector 3, and the second insulating retaining ring 53 is covered and disposed on the first insulating retaining ring 44.
