Description

Technical Field

[0001] This utility model relates to the field of electrical welding technology, and in particular to a coaxial cable welding clamp. Background Technology

[0002] Cable soldering is a process of joining two or more cables together. By heating, applying pressure, or using filler materials (such as solder), a strong electrical and mechanical connection is formed between the metal conductors of the cables. This connection method ensures stable and efficient current transmission between different cables and provides high connection strength to prevent the cables from loosening or breaking during use.

[0003] In the prior art, such as the patent publication number CN220698491U "A Coaxial Cable Welding Clamp", a limiting post is connected to the lower end of the retaining ring by bolt thread and a retaining block is inserted into the inner surface of the fixing block. One end of the limiting post is inserted with an extension post for movement. The outer surface of the retaining block is fixedly connected with a retaining plate for pressing. The outer surface of the retaining plate is fixedly connected with a handle for gripping.

[0004] However, in the existing technology, when connecting cables, clamps can be used to fix the cables and avoid electrical safety accidents that are easy to occur when welding cables by hand. However, when the clamp positioning is off, it is easy to cause the two cables to be misaligned on the same axis, which will increase the gap between the two cables. This will not only lead to a weak cable connection, but also cause waste due to the use of too much solder. Utility Model Content

[0005] This utility model mainly provides a cable welding clamp that improves the positioning accuracy of two cables and enhances the welding strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coaxial cable welding clamp, comprising:

[0007] A support base, the top of which is fixedly connected to a vertical bearing, the inner sidewall of which is rotatably connected to a rotating shaft, both ends of which are provided with external threads, and both ends of the support base are fixedly connected to a sliding seat.

[0008] A docking sleeve is slidably connected to a sliding seat. An annular seat is fixedly connected to the outer wall of the docking sleeve. A snap-fit ​​post is snapped into the outer wall of the annular seat. A swing frame is fixedly connected to one end of the snap-fit ​​post. A hinge seat is provided in the middle of the swing frame. The swing frame is rotatably connected to the support seat through the hinge seat. A sliding block is provided at the bottom of the swing frame. The sliding block is connected to the rotating shaft through an external thread.

[0009] An inner clamping plate is located on the inner wall of the mating sleeve. A connecting plate is fixedly connected to the outer wall of the mating sleeve. A screw is threadedly connected to the middle position of the connecting plate, and the screw is rotatably connected to the inner clamping plate.

[0010] Preferably, both ends of the connecting plate are slidably connected to positioning posts. One end of the positioning post penetrates the inner wall of the mating sleeve and is fixedly connected to the inner clamping plate. The other end of the positioning post is fixedly connected to a circular baffle. The positioning posts are installed at both ends of the connecting plate to limit the movement, so that when the screw drives the inner clamping plate to clamp inward, the inner clamping plate will not rotate due to the action of the screw, but only ensures that the inner clamping plate moves on a straight trajectory.

[0011] Preferably, a second sliding seat is slidably connected to the outer wall of the docking sleeve, and the bottom end of the second sliding seat is fixedly connected to the support seat. By adding a second sliding seat to the outer wall of the docking sleeve, the principle of two points determining a straight line is used to ensure that the docking sleeve moves along the axial direction and avoids deviation during docking.

[0012] Preferably, a crank handle is fixedly connected to one end of the rotating shaft, and a rubber sleeve is fitted on the outer wall of the crank handle. By setting a crank handle on one side of the rotating shaft, it is convenient to manually control the rotation of the rotating shaft, thereby controlling the two docking sleeves to drive the two cables to dock and position.

[0013] Preferably, each of the outer walls of the sliding block is rotatably connected to a hinge seat. The sliding block is rotatably connected to the swing frame through the hinge seat. By setting the hinge seat on the outer side of the sliding block, the swing frame and the sliding block are at different angles when the sliding block moves to different positions, and the swing frame and the sliding block always remain connected.

[0014] Preferably, the bottom end of the sliding block is provided with a slot, and the top surface of the bracket is fixedly connected with a guide rail. The sliding block slides linearly along the guide rail through the slot. By setting the guide rail on the bracket, the sliding position of the sliding block is positioned to avoid the sliding block leaving the sliding trajectory and causing adverse effects on the docking of the docking sleeve.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, two cables that need to be connected are passed through the inside of the connecting sleeve. By using a wrench to tighten the screw, the inner clamping plate can be moved towards the axis, thereby clamping the cable ends. By rotating the handle, the rotating shaft is driven by the threaded outer ribbon, and the two sliding blocks move towards each other, driving the two cable ends to approach and connect. The welding process of the two cables can be completed by using welding equipment, achieving the effect of quickly positioning the two cables on the same axis.

[0017] 2. In this utility model, by adding a sliding seat two to the outer wall of the docking sleeve, the principle of two points determining a straight line is used to ensure that the docking sleeve moves along the axial direction, avoiding deviation during docking. Positioning pins are installed at both ends of the connecting plate to limit the movement, so that when the screw drives the inner clamping plate to clamp inward, the inner clamping plate will not rotate due to the action of the screw, but only ensures that the inner clamping plate moves on a straight trajectory, further improving the docking accuracy when welding two cables.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Please see Figure 1 - Figure 5 This utility model provides a coaxial cable welding clamp, comprising:

[0027] The bracket 1 has a vertical bearing 4 fixedly connected to its top end. A rotating shaft 2 is rotatably connected to the inner side wall of the vertical bearing 4. Both ends of the rotating shaft 2 are provided with external threads 3. Both ends of the bracket 1 are fixedly connected with sliding seats 6.

[0028] The mating sleeve 7 is slidably connected to the sliding seat 6. The outer side wall of the mating sleeve 7 is fixedly connected to the ring seat 12. The outer side wall of the ring seat 12 is clamped to the clamping post 14. One end of the clamping post 14 is fixedly connected to the swing frame 11. The middle of the swing frame 11 is provided with the hinge seat 13. The swing frame 11 is rotatably connected to the support seat 1 through the hinge seat 13. The bottom end of the swing frame 11 is provided with the sliding block 8. The sliding block 8 is threadedly connected to the rotating shaft 2 through the external thread 3.

[0029] Inner clamping plate 19 is located on the inner wall of the mating sleeve 7. A connecting plate 16 is fixedly connected to the outer wall of the mating sleeve 7. A screw 17 is threadedly connected to the middle position of the connecting plate 16. The screw 17 is rotatably connected to the inner clamping plate 19.

[0030] The support base 1 has two docking sleeves 7 at its two ends, and the two docking sleeves 7 are located on the same axis. The welding equipment is located on the side of the support base 1. The two cables to be welded are passed through the docking sleeves 7, and the two cables are positioned on the axis. The rotating shaft 2 has reverse threaded external threads 3 on both sides. When the two cables are docked, the rotating shaft 2 is rotated to one side, which makes the two sliding blocks 8 move towards each other and open outward. Since the middle of the swing frame 11 is installed on the support base 1 through the hinge seat 2 13, when the sliding block 8 drives the bottom end of the swing frame 11 to open outward, the top ends of the two swing frames 11 will move closer to the middle, thereby driving the two cable ends to move closer and dock. The welding equipment can be used to complete the welding process of the two cables. The inner clamping plate 19 is installed on the two adjacent ends of the docking sleeve 7. The position of the inner clamping plate 19 is controlled by the screw 17 on the outside of the docking sleeve 7. The inner clamping plate 19 can be moved towards the axis by tightening the screw 17 with a wrench, thereby clamping the cable ends.

[0031] like Figure 5 As shown, both ends of the connecting plate 16 are slidably connected with positioning pins 18. One end of the positioning pin 18 penetrates the inner sidewall of the docking sleeve 7 and is fixedly connected to the inner clamping plate 19. The other end of the positioning pin 18 is fixedly connected to a round baffle. The positioning pins 18 are installed at both ends of the connecting plate 16 to limit the movement, so that when the screw 17 drives the inner clamping plate 19 to clamp inward, the inner clamping plate 19 will not rotate due to the action of the screw 17, but only ensures that the inner clamping plate 19 moves on a straight trajectory.

[0032] like Figure 4As shown, a sliding seat 2 15 is slidably connected to the outer wall of the docking sleeve 7. The bottom end of the sliding seat 2 15 is fixedly connected to the support seat 1. By adding a sliding seat 2 15 to the outer wall of the docking sleeve 7, the principle of two points determining a straight line is used to ensure that the docking sleeve 7 moves along the axial direction and avoids deviation during docking.

[0033] like Figure 2 As shown, a crank handle 5 is fixedly connected to one end of the rotating shaft 2. A rubber sleeve is fitted on the outer wall of the crank handle 5. By setting the crank handle 5 on one side of the rotating shaft 2, it is easy to manually control the rotation of the rotating shaft 2, thereby controlling the two docking sleeves 7 to drive the two cables to dock and position.

[0034] like Figure 3 As shown, the outer side wall of the sliding block 8 is rotatably connected to the hinge seat 10. The sliding block 8 is rotatably connected to the swing frame 11 through the hinge seat 10. By setting the hinge seat 10 on the outer side of the sliding block 8, the swing frame 11 and the sliding block 8 are at different angles when the sliding block 8 moves to different positions. The swing frame 11 and the sliding block 8 always remain connected.

[0035] like Figure 3 As shown, the bottom end of the sliding block 8 is provided with a slot 9, and the top surface of the bracket 1 is fixedly connected with a guide rail. The sliding block 8 slides linearly along the guide rail through the slot 9. By setting the guide rail on the bracket 1, the sliding position of the sliding block 8 is positioned to prevent the sliding block 8 from leaving the sliding track and causing adverse effects on the docking of the docking sleeve 7.

[0036] The method of use and working principle of this device: First, pass the two cables to be welded through the inside of the connecting sleeve 7 to position the two cables on the axis. Then, use a wrench to tighten the screw 17 to move the inner clamp 19 towards the axis, thereby clamping the cable ends.

[0037] Then, the hand-cranked rotating shaft 2 rotates, and through the threaded external threads 3 at both ends, the two sliding blocks 8 move towards each other, causing the bottom of the swing frame 11 to be pushed outward. The tops of the two swing frames 11 will then move closer to the center, thereby bringing the two cable ends closer together and connecting them. The welding process of the two cables can then be completed using welding equipment.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
