Description

Technical Field

[0001] The invention belongs to the technical field of mechanical tools, and in particular relates to a cable plugging tool. Background Art

[0002] Cables are widely used in various fields of life and production. The connection and removal of cable plugs are also the most common operations in the construction and maintenance of cables. At present, the connection of cable plugs is mainly completed manually. Although the method of manually connecting cable plugs is easy to achieve when the working space is unlimited, there is a risk of damaging the pins due to the force applied by the hand. Especially in a small working space, the force applied by the hand is more likely to tilt, which can easily cause the pins of the cable plug to tilt and be damaged, making it impossible to continue to use. In addition, in a small working space, it is difficult for the human hand to fully extend, and when connecting the plug, the force applied to the plug is small, which will cause the cable plug to be unstable or even unable to connect. Therefore, the operation of manually connecting cable plugs in a small space is not only inefficient, but also easy to damage the pins of the cable plug.

[0003] Therefore, there is an urgent need for a cable plugging tool that can save effort and efficiently plug cable connectors in a narrow space without damaging the plug pins. Summary of the invention

[0004] In view of this, the present invention provides a cable plugging tool suitable for working in a narrow space, which can save effort and efficiently realize the plugging of cable connectors in a narrow space without damaging the plug pins.

[0015] A positioning block is installed on the inner side of the positioning body.

[0016] The adjusting component passes through the through hole II, one end of which is connected to the positioning block and the other end is suspended. The adjusting component can move forward and backward along the through hole II to drive the positioning block to move forward and backward.

[0017] Preferably, the positioning surface of the positioning block is an arc-shaped surface at the upper end and a plane at the lower end, and the arc-shaped surface is tangent to the plane.

DETAILED DESCRIPTION

[0032] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and should be understood that the protection scope of the present invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific variations and combinations that do not deviate from the essence of the present invention based on the technical revelations disclosed by the present invention, and these variations and combinations are still within the protection scope of the present invention.

[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1and Figure 2 The cable plugging tool shown is suitable for working in a narrow space, characterized in that the tool comprises: a handle, a plug connector 5, a guide column 6, a positioning module and a spring 8.

[0035] The handle is composed of handle I 1 and handle II 2, and handle I 1 and handle II 2 are hingedly connected at a portion close to the handle end;

[0036] like Figure 3 As shown, the connection end of the handle II 2 and the positioning module is square.

[0037] like Figure 4 As shown, a through hole 503 is formed on the upper surface of the plug connector 5, and a through slot is formed at the connecting end of the plug connector 5 and the handle 11. One end of the handle 11 is inserted into the through slot and is hingedly connected to the plug connector 5 by a pin.

[0038] After the spring 8 is sleeved on the guide column 6, one end thereof passes through the through hole 503, and the other end thereof is fixedly connected to the positioning module.

[0039] like Figure 1 The positioning module shown further comprises: a positioning body 3 , a positioning block 4 and an adjusting component. In this embodiment, the adjusting component is a pushing screw 7 .

[0040] like Figure 5 A stepped positioning hole 301 is provided on the outer upper surface of the positioning body 3, a square groove 302 is provided at the outer corner, a threaded hole is provided at the bottom of the square groove 302, and the square connecting end of the handle II 2 is embedded in the square groove 302 for fixed connection; a through hole II 303 is provided on the side of the positioning body 3; the guide column 6 is connected to the positioning body 3, and the specific connection method is: one end of the guide column 6 is inserted into the stepped positioning hole 301 and is fixedly connected to the positioning body 3 by welding or other methods, and the spring 8 is clamped between the stepped positioning hole 301 and the lower surface of the plug connector 5.

[0041] The positioning block 4 is located inside the positioning body 3. Figure 6 As shown, the positioning block 4 has a through hole, and a step surface I 401 and a step surface II 402 are respectively provided at both ends of the through hole. Figure 7 As shown, the upper end of the positioning surface of the positioning block 4 is an arc-shaped curved surface, and the lower end is a plane, and the arc-shaped curved surface is tangent to the plane.

[0042] like Figure 8 As shown, one end face of the push screw 7 is provided with a threaded hole II 701, as shown in FIG. Figure 1 and Figure 2 As shown, one end surface of the push screw 7 with a threaded hole II 701 is tightly pressed against the step surface I 401, and the screw 9 passes through the step surface II 402 and the through hole in the middle of the positioning block 4 and is connected to the threaded hole II 701.

[0043] When plugging the cable plug, an upward force is applied to the handle 12, and the plug connector 5 moves vertically downward along the guide column 6 to plug the cable plug. After the plugging is completed, the force is removed and the plug connector 5 can return to the initial position under the action of the spring 8. The plug connector 5 always applies a vertical force to the cable plug under the restriction of the guide column 6, preventing the cable pin from bending due to the inclination of the force during the plugging process.

[0044] By turning the push screw 7, the positioning block 4 can be moved forward and backward relative to the inner surface of the positioning body 3, so that when the tool of the present invention is used, the positioning block 4 is moved until it is tightly fitted on the selected reference surface, which ensures that the force of the plug connector 5 is always perpendicular to the force-bearing surface of the cable plug, and also tightens the plugging tool, making it convenient, accurate and efficient to plug in the cable plug.

[0045] The handle II 1 and the handle I 2 form a lever mechanism, which only requires a small grip force to make the pressure block generate a large pressure, thereby improving the working efficiency of cable plugging; the handle II 1 and the handle I 2 are relatively long, which makes it convenient for the tool to be inserted into a narrow space for operation.

[0046] The upper end of the positioning block 4 is an arc surface, which is suitable for the working environment of arc positioning reference surfaces such as cylindrical surfaces. The lower end of the positioning block 4 is a plane, which is suitable for the working environment of plane reference surfaces, which greatly improves the applicable working environment of the present invention.

[0047] The clamping head of the plug connector 5 is a vertical thin plate structure, which is convenient for extending into a narrow space to clamp the cable plug and plug the cable.

[0048] like Fig. 9 , Fig.10 As shown, the guide head 1501 of the upper cable plug 15 is slightly inserted into the guide groove 1601 of the lower cable plug 16, and then the cable-specific plugging tool 17 provided by the present invention, which is suitable for narrow space operations, is used to extend the plug connector 5 into the narrow space, and the position of the plug connector 5 is adjusted so that the clamping head is just symmetrically clamped on the two ends of the upper cable plug 15, and then the push screw 7 is adjusted so that the arc surface of the positioning block 4 is tightly fitted on the cylindrical surface (the selected reference surface) to ensure that the force of the pressing block is always perpendicular to the pressed surface of the upper cable plug 15 (that is, the pressure is always parallel to the pin) during the plugging process, and to ensure that the plugging tool can operate stably and efficiently, and finally, by lightly holding the handle, the pin of the upper cable plug 15 can be smoothly inserted into the lower cable plug, so that the plugging of the cable plugs can be conveniently and reliably realized.

[0049] In a non-narrow space, the method of using the plugging tool is the same as in a narrow space. It can effectively prevent the pins from bending due to tilting force during the plugging process, thereby ensuring the reliability of cable plugging.
