Description

Technical Field

[0001] This utility model belongs to the field of cable connector technology, and specifically relates to a cable connector that facilitates connection. Background Technology

[0002] A cable joint is also called a cable termination. After a cable is laid, in order to make it a continuous line, the sections of the cable must be connected into a whole. These connection points are called cable joints.

[0003] When connecting two cables, the worker needs to insert the two cables into the two ends of the cable connector, align the two cables, and finally use bolts to tighten the cables, thus completing the connection between the two cables.

[0004] However, existing cable connector structures are too simple. For example, a patent document with publication number CN219268465U8 discloses "a waterproof and sealed cable connector", which includes a cable connector body. The cable connector body has cable clamping claws at both ends. Tightening sleeves are installed around the cable clamping claws at both ends of the cable connector body. A sealing rubber ring is installed at the center of the outer side of the tightening sleeve. Observation windows are installed at the center of the front and back of the cable connector body. A threaded tube is installed at the center of the top of the cable connector body. A sealing cap is installed around the threaded tube. A screw hole is opened at the bottom of the threaded tube and penetrates the inside of the cable connector body. This application describes a cable connector that uses cable clamping claws in its main body to tighten both ends of the connector with a tightening sleeve. This clamps and seals the cables on both sides of the connector. However, it only serves a connection function and cannot assist workers in aligning the two cables. In actual use, workers need to manually align the two cables and maintain a stable position before tightening the bolts to press the cables together. This connection method requires multiple people to work together, making it inconvenient to use. Furthermore, it is difficult to press and position irregularly shaped cables, thus limiting the device's practicality. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a convenient cable connector. It uses a positioning mechanism to center and adjust the cables at both ends, and then uses an adjustment mechanism to squeeze and position irregularly shaped cables. It is convenient to use and highly practical.

[0006] The technical solution adopted by this utility model is a convenient cable connector, including a cable connector body, clamping bolts and a positioning mechanism. The clamping bolts are an even number and are symmetrically threaded onto the cable connector body. The positioning mechanism includes two sets of positioning units, which are respectively installed at both ends of the cable connector body.

[0007] The positioning unit includes a turntable, a curved arm, a pressure rod, a pressure roller, and a drive assembly. The turntable is rotatably connected to the end of the cable connector body. Several curved arms are rotatably connected to the outside of the turntable in a circumferential shape. The pressure roller corresponds to each curved arm and is rotatably connected. The pressure rod corresponds to each pressure roller. One end of the pressure rod is rotatably connected to the inner wall of the turntable, and the other end is fixedly connected to the pressure roller. The drive assembly is used to drive the turntable to rotate so that the pressure roller retracts or expands.

[0008] Furthermore, the drive assembly includes a threaded rod, a slider, a slide bar, and a limiting block. The turntable has an arc-shaped groove. The bottom of the threaded rod is rotatably connected to the cable connector body. The slider is threaded onto the threaded rod. The slide bar is fixedly connected to the slider and passes through the arc-shaped groove. The limiting block is fixedly connected to the end of the slide bar located outside the arc-shaped groove.

[0009] Furthermore, a knob is fixedly connected to the top end of the threaded rod.

[0010] Furthermore, an adjustment mechanism is installed on the pressure roller, the adjustment mechanism including a lead screw and a handle, the lead screw passing through the pressure roller through a threaded connection, and the handle being fixedly connected to the outer end of the lead screw.

[0011] Furthermore, a rubber block is fixedly connected to the inner end of the lead screw.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This convenient cable connector, through the positioning mechanism set on both sides of the cable connector body, can keep the two cables in a stable centered state inside the cable connector body. By centering the two cables, the two cables can be connected together, so there is no need to connect them by hand. Just turn the clamping bolt to tighten the cables, which is very convenient to use.

[0014] 2. This convenient cable connector allows you to rotate the screw to press the rubber block against the outer wall of the cable. The screw and rubber block together can then compress the cable, making it easier to position cables that are not perfectly round, thus increasing its practicality. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be further described in detail below with reference to the accompanying drawings of the embodiments of this utility model.

[0023] Reference Figures 1 to 6 The present invention provides a convenient cable connector, comprising a cable connector body 1, clamping bolts 2, and a positioning mechanism 3. The clamping bolts 2 are an even number and symmetrically threaded onto the cable connector body 1. Rotating the clamping bolts 2 can clamp the cable inside the cable connector body 1. The positioning mechanism 3 includes two sets of positioning units, which are respectively installed at both ends of the cable connector body 1. The positioning mechanism 3 is used to adjust the cables at both ends of the cable connector body 1 to make them centered and aligned, facilitating connection.

[0024] The positioning unit includes a turntable 33, a crank arm 310, a pressure rod 32, a pressure roller 38, and a drive assembly. The turntable 33 is rotatably connected to the end of the cable connector body 1. Several crank arms 310 are rotatably connected to the outside of the turntable 33 in a circumferential shape. The pressure rollers 38 correspond one-to-one with the crank arms 310 and are rotatably connected. The pressure rods 32 correspond one-to-one with the pressure rollers 38. One end of the pressure rod 32 is rotatably connected to the inner wall of the turntable 33, and the other end is fixedly connected to the pressure roller 38. The drive assembly is used to drive the turntable 33 to rotate so that the pressure rollers 38 are positioned correctly. The roller 38 can be retracted or expanded. The drive assembly includes a threaded rod 31, a slider 35, a slide bar 36, and a limiting block 37. An arc-shaped inclined groove 39 is provided on the turntable 33. The bottom of the threaded rod 31 is rotatably connected to the cable connector body 1. The slider 35 is threadedly fitted onto the threaded rod 31. The slide bar 36 is fixedly connected to the slider 35 and passes through the arc-shaped inclined groove 39. The limiting block 37 is fixedly connected to one end of the slide bar 36 located outside the arc-shaped inclined groove 39. A knob 34 is fixedly connected to the top of the threaded rod 31.

[0025] Rotating the threaded rod 31 via the knob 34 causes the threaded slider 35 connected to it to move downwards. At the same time, the slider 35 causes the sliding rod 36 to move downwards against the inner wall of the arc-shaped groove 39. Since the side wall of the limiting block 37 is in contact with the outer wall of the turntable 33, the sliding rod 26 can drive the turntable 33 to rotate through the arc-shaped groove 39 when it moves. One end of the pressure rod 32 is hinged to the inner wall of the cable connector body 1, and the other end of the pressure rod 32 is fixedly installed with a pressure roller 38. The side wall of the turntable 33 is hinged with a crank arm 310. When the turntable 33 rotates, it will squeeze the crank arm 310, and the crank arm 310 will squeeze the pressure roller 38. Therefore, the rotation of the turntable 33 and the crank arm 310 can drive the pressure rod 32 to rotate synchronously and make the pressure rollers 38 move closer to each other until the pressure rollers 38 press against the outer wall of the cable. The pressure rollers 38 can then clamp the cable so that the cable is in a stable centered state inside the cable connector body 1.

[0026] An adjustment mechanism 4 is installed on the pressure roller 38. The adjustment mechanism 4 includes a lead screw 41 and a handle 42. The lead screw 41 passes through the pressure roller 38 through a threaded connection, and the handle 42 is fixedly connected to the outer end of the lead screw 41. A rubber block 43 is fixedly connected to the inner end of the lead screw 41.

[0027] By rotating the screw 41 through the handle 42, the screw 41 moves the rubber block 43 out of the pressure roller 38 and abuts against the outer wall of the cable. The screw 41 and the rubber block 43 can press the cable tightly, thereby positioning the cable that is not perfectly round.

[0028] In summary, the working principle of this utility model is as follows: First, insert two cables into the cable connector body 1 from both ends and make them fit together. Then, rotate the threaded rod 31 by the knob 34 to drive the slider 35 connected to it to move downward. At the same time, the slider 35 will drive the sliding rod 36 to fit against the inner wall of the arc-shaped inclined groove 39 and move downward. The sliding rod 36 will press the arc-shaped inclined groove 39 downward, thereby causing the turntable 33 to rotate. As the turntable 33 rotates, it will press the curved arm 310, and the curved arm 310 will press the pressure roller 38. This causes the pressure roller 38 to drive the pressure rod 32 to rotate. The rotation of the turntable 33, in conjunction with the crank arm 310, can drive the pressure rod 32 to rotate synchronously and make the pressure rollers 38 move closer to each other until the pressure rollers 38 press against the outer wall of the cable. At this time, the cable is clamped by the three sets of pressure rollers 38, which can keep the cable in a stable centered state inside the cable connector body 1. By centering the two cables, the two cables can be connected together, so there is no need to connect them by hand. Just rotate the clamping bolt 2 to press the cable tight, which is very convenient to use.

[0029] When the cable is squeezed and deformed into a non-circular state, causing the pressure roller 38 to be unable to fully clamp the cable, the cable is first initially positioned by the three sets of pressure rods 32 and the three sets of pressure rollers 38. Then, the screw 41 is rotated by the handle 42, causing the screw 41 to move the rubber block 43 out of the pressure roller 38 and abut against the outer wall of the cable. At this time, the cable can be pressed tightly by the screw 41 and the rubber block 43, which can position the non-circular cable and make it more practical.
