[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0025] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present invention.

[0026] In order to solve the problem that the lead terminal clamp in the prior art is inconvenient to use and operate, the present invention provides a monkey head type terminal clamp.

[0027] Such as Figures 1 to 5A kind of monkey head type wire clamp shown in the figure includes a main body part 10, a movable part 20, a fastening bolt 30 and a lead bolt 40. The main body part 10 has a lead installation part 11 for installing the lead and an inclined surface clamping part 12 for clamping the main wire. The movable part 20 is movably arranged relative to the main body part 10 and jointly forms a clamping area for clamping the main wire with the inclined surface clamping part 12. The fastening bolt 30 is threadedly connected to the main body part 10. The movable part 20 is sleeved outside the fastening bolt 30. A stop structure is arranged outside the fastening bolt 30. When the fastening bolt 30 rotates, the stop structure squeezes the movable part 20 and reduces the size of the clamping area to clamp the main wire. The lead bolt 40 is connected to the lead and is arranged through the lead installation part 11.

[0028] In this embodiment, through the cooperation between the above-mentioned various components, the main body part 10 and the movable part 20 are used as the main clamping components, the fastening bolt 30 is used as the component for controlling the clamping or releasing of the main body part 10 and the movable part 20, and the lead bolt 40 is used as the component for connecting the lead. When in use, the lead is connected to the lead bolt 40, the lead bolt 40 is installed on the lead installation part 11, and then the fastening bolt 30 is rotated, so that the stop structure on the fastening bolt 30 squeezes the movable part 20, and the movable part 20 moves towards the direction close to the main body part 10, and the clamping area gradually shrinks, thereby clamping the main wire placed in the clamping area. The above setting method can realize the clamping and releasing of the main wire by tightening or loosening the fastening bolt 30, and the lead is separately connected through the lead bolt 40, thus simplifying the structure of the monkey head type wire clamp, facilitating daily use and operation such as wiring and wire replacement, and can be directly connected to the stirrup type wire clamp, meeting the flexibility of various operation requirements, and the operation is safe and reliable.

[0029] In this embodiment, the main body part 10 is provided with a slideway along the axis direction of the fastening bolt 30. The movable part 20 has a connecting part 21. The connecting part 21 is movably arranged in the slideway and slides along the opening direction of the slideway. That is to say, the axis of the fastening bolt 30, the opening direction of the slideway and the sliding direction of the movable part 20 relative to the main body part 10 are the same. And one end of the slideway is an open side, which is communicated with the outside of the main body part 10. The connecting part 21 extends into the slideway from the open side. Moreover, the connecting part 21 is also provided with a through hole for the fastening bolt 30 to pass through. In this way, while the fastening bolt 30 passes through the through hole, it also passes through the slideway. When the fastening bolt 30 is tightened, the stop structure can squeeze and push the movable part 20 close to the main body part 10 to clamp the main wire. Different from the threaded cooperation mode between the main body part 10 and the fastening bolt 30, the through hole on the movable part 20 is a non-threaded hole, and its diameter is slightly larger than the diameter of the fastening bolt 30. The rotation of the fastening bolt 30 realizes the sliding of the movable part 20 by the stop structure squeezing the movable part 20, rather than directly driving the movable part 20 to move through the thread.

[0030] Such asFigure 1 As shown, the movable member 20 has a first limiting structure 22 protruding therefrom, and the main body member 10 has a second limiting structure 13 protruding therefrom. Both the first limiting structure 22 and the second limiting structure 13 protrude radially along the fastening bolt 30, and the second limiting structure 13 is located on the movement path of the first limiting structure 22. Thus, when the movable member 20 moves in the direction of releasing the main wire, that is, when the connecting portion 21 moves towards the open side of the slideway, namely when moving downward in the Figure 1 direction, the first limiting structure 22 will gradually approach the second limiting structure 13 until it abuts against the second limiting structure 13. At this time, the movable member 20 moves to the limit position, and the size of the clamping area reaches the preset maximum value. In this way, the effect of controlling the movement range of the movable member 20 can be achieved, avoiding the situation that the movable member 20 moves too much and falls off from the main body member 10, and ensuring the integrity of the monkey head type wire clamp.

[0031] In addition to the above-mentioned first limiting structure 22, the movable member 20 further has a third limiting structure 23 which also protrudes radially along the fastening bolt 30 and is located on the side of the stop structure away from the main body member 10. The movable member 20 in this embodiment has a U-shaped structure, one end of which is the connecting portion 21 extending into the main body member 10, and the first limiting structure 22 is located at this end, while the other end is the third limiting structure 23 which is in limiting cooperation with the stop structure. When the fastening bolt 30 is loosened and withdrawn from the main body member 10, that is, when moving downward in the Figure 1 direction, the stop structure will gradually approach the third limiting structure 23 until it abuts against the third limiting structure 23. At this time, combined with the limiting effect between the first limiting structure 22 and the second limiting structure 13, the result that the movement of the movable member 20 is restricted can be produced, so that the fastening bolt 30 moves to the limit position and the fastening bolt 30 cannot be further loosened, thereby achieving the effect of preventing the fastening bolt 30 from withdrawing from the main body member 10 and avoiding the situation that the fastening bolt 30 falls off from the main body member 10, and ensuring the integrity of the monkey head type wire clamp.

[0032] A plurality of the above-mentioned first limiting structure 22, second limiting structure 13 and third limiting structure 23 can be provided as needed, and they can be arranged in sequence along the circumferential direction of the fastening bolt 30.

[0033] The stop structure of this embodiment includes a base 31. The base 31 is in a disc shape and is sleeved outside the fastening bolt 30 and fixedly connected to the fastening bolt 30. The base 31 also protrudes radially along the fastening bolt 30. Axially along the fastening bolt 30, the base 31 is located between the first limiting structure 22 and the third limiting structure 23. In this way, when the fastening bolt 30 is tightened, one end face of the base 31 can squeeze the movable part 20 so that the movable part 20 moves towards the main body part 10, thereby clamping the main wire. When the fastening bolt 30 is loosened, the other end face of the base 31 can abut against the third limiting structure 23, thereby playing a limiting role.

[0034] Optionally, the stop structure further includes a gasket 32. The gasket 32 is sleeved outside the fastening bolt 30 and abuts against the base 31. In this embodiment, a gasket 32 is provided on the end face side of the base 31 facing the first limiting structure 22. When the fastening bolt 30 is tightened, the gasket 32 is in direct contact with the movable part 20. The base 31 squeezes the gasket 32 to realize the extrusion and pushing of the movable part 20. The gasket 32 can play a buffering role to avoid damage, noise generation, etc. caused by the collision between the base 31 and the movable part 20. Of course, a gasket 32 can also be provided on the end face side of the base 31 facing the third limiting structure 23 according to needs, and the number of gaskets 32 can also be set according to needs.

[0035] In this embodiment, the inclined clamping part 12 has a first clamping surface 14, and the movable part 20 has a second clamping surface 24. The first clamping surface 14 and the second clamping surface 24 form a clamping area, and both the first clamping surface 14 and the second clamping surface 24 are arc-shaped. The first clamping surface 14 is located on the side of the inclined clamping part 12 opposite to the inclined surface. It can be set in an arc shape or an L shape, etc. The second clamping surface 24 is located at the corner of the C-shaped structure close to the first clamping surface 14 and is preferably set in an arc shape to better clamp the main wire.

[0036] As Figure 4 shown, this embodiment also provides a lead bolt 40 for connecting the lead wire and a lead wire installation part 11 for installing the lead bolt 40. The lead wire installation part 11 is provided with a lead wire installation hole 15 for the lead bolt 40 to pass through. The lead wire installation hole 15 is a threaded hole. The lead bolt 40 includes a threaded section 41 and a lead section 42. The threaded section 41 passes through the lead wire installation hole 15, thereby realizing the connection between the lead bolt 40 and the main body part 10. The lead section 42 is provided with a lead wire hole 43, and the lead wire is connected at the lead wire hole 43, thereby realizing the connection between the lead bolt 40 and the lead wire and ensuring that the lead wire is stably in full contact with the monkey head type terminal clamp. In this way, both the monkey head type terminal clamp and the main wire and the lead wire can be quickly connected and replaced, thus greatly facilitating the operation.

[0037] As Figure 5As shown in the figure, in this embodiment, an arc surface 16 is formed on the side surface of the lead mounting portion 11. The arc surface 16 is in abutting fit with the side wall of the lead segment 42, and clamps and fixes the lead placed in the lead hole 43, thereby realizing the quick fixing and quick replacement of the lead.

[0038] Optionally, as Figure 1 shown, an operation ring 33 for tightening or loosening the fastening bolt 30 is provided at one end of the fastening bolt 30 away from the main body member 10. An operator can turn the fastening bolt 30 through the operation ring 33, improving the use experience.
