[0005] In view of the above problems, a safety type cable wired connector which is anti-fracture is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a breakage-resistant safety cable wired connector. By adopting the device to work, the problem that the traditional cable connector in the above background is relatively simple in structure, and the cable is simply passed through the through groove, so that the cable connection is not tight enough and is prone to loosening after long-term use, causing the cable to detach from the connector component, affecting use and even causing safety hazards is solved.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a break-proof safety cable wired connector, comprising a clamping assembly and a connecting slot plate arranged on both sides of the clamping assembly, a limiting assembly is arranged on one side of the two groups of connecting slot plates, a first cable body is arranged between the two groups of limiting assemblies, the limiting assembly comprises a first ring body and a mounting cavity block fixedly connected to one side of the first ring body, two groups of mounting cavity blocks are arranged, one side of the mounting cavity block is provided with a through cavity groove, two groups of through cavity grooves are arranged, a spring is fixedly connected to the inner cavity of the through cavity groove, a limiting arc plate is arranged in the inner cavity of the first ring body, the clamping assembly comprises a second ring body arranged on one side of the connecting slot plate, the connecting slot plate is fixedly connected between the first ring body and the second ring body, one side of the second ring body is threadedly connected with a threaded rod, and two groups of threaded rods are arranged.

[0008] Preferably, the limiting assembly also includes a pull rod fixedly connected to one side of the limiting arc plate, one end of the pull rod passes through the first ring body and the mounting cavity block and extends to the outside of the mounting cavity block, the pull rod is slidably connected to the mounting cavity block, and the pull rod is slidably connected to the first ring body.

[0009] Preferably, a connecting plate is provided on one side of the installation cavity block, the connecting plate is fixedly connected to the outer periphery of the pull rod, the two groups of springs are fixedly connected to the bottom of the connecting plate, and a pulling plate is provided on one side of the connecting plate, which is fixedly connected to one end of the pull rod.

[0010] Preferably, the clamping assembly further comprises a clamping plate arranged in the inner cavity of the second ring body, and an insulating pad is bonded to the inner wall of the clamping plate.

[0011] Preferably, one end of the threaded rod passes through the second ring body and extends to the inner cavity of the second ring body, a bearing is provided at one end of the threaded rod, and the clamping plate is fixedly connected to one side of the bearing.

[0012] Preferably, one end of the threaded rod away from the bearing is fixedly connected with a knob, and the second ring body, the first ring body and the connecting through-slot plate are all parts made of brass material.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model proposes a safety type cable wired connector that prevents breakage. The first ring body, the second ring body and the connecting slot plate are all made of brass. Brass has good machinability, good mechanical properties, can withstand cold and hot pressure processing, is easy to weld, and has good corrosion resistance after being nickel-plated on the surface, thereby improving the anti-breakage performance of the cable wired connector. When the cable connector is needed for wiring, the first cable body extends from the limit assembly into the clamping assembly, and the second cable body extends from another set of limit assemblies into the clamping assembly. Before connecting the cables, the limit assembly is used to limit and stabilize the cables. Before the cable body passes through the first ring body, the two sets of pulling plates are pulled toward the side away from the first ring body. The pulling plate will drive the connecting plate and the pull rod to move toward the side away from the first ring body at the same time. At this time, the two sets of springs are stretched and deformed by the connecting plate, and at the same time, the pull rod drives the limit assembly corresponding to one end thereof. The positioning arc plate moves toward the inner wall side of the first ring body. When the spacing between the two sets of limiting arc plates is adjusted to an appropriate distance according to the thickness of the cable body, the cable is passed through the two sets of limiting arc plates and extended into the connecting slot plate. After the cable passes through the connecting slot plate and enters the inner cavity of the second ring body, the two sets of pulling plates are released. Due to the restoring force generated by the spring deformation, the spring will drive the connecting plate and the pull rod to move toward the side close to the first ring body, and the connecting plate will contact the installation cavity block again. The pull rod will push the limiting arc plate to move toward the side close to the cable body until the two sets of limiting arc plates limit the cable body firmly. This setting stabilizes the cables in advance through two sets of limiting components, which can prevent the cable body from slipping out of the second ring body or even falling off from one side of the cable connector during the docking and fixing process of the two cables. This is beneficial to the subsequent cable assembly work and improves the practicality of the device.

[0015] 2. The utility model provides a safety cable wired connector that prevents breakage. The first cable body passes through a limiting component and a connecting slot plate on one side thereof to enter the inner cavity of the second ring body. Subsequently, the second cable body passes through another group of limiting components and a connecting slot plate to enter the inner cavity of the second ring body. At this time, the first cable body and the second cable body are between the two groups of clamping plates. After the cable cores of the first cable body and the second cable body are in contact with each other and connected, in order to further fix the connection between the two groups of cable bodies, the operator rotates the two groups of knobs, and the knobs drive the threaded rods to rotate. A bearing is provided at one end of the threaded rod. The threaded rod pushes the clamping plate on one side thereof to move toward the side close to the cable until the two groups of threaded rods push the two groups of clamping plates to be tightly clamped on the sides of the cable connection. The knobs are stopped from being rotated. At this time, the two groups of insulating pads are tightly wrapped around the outer periphery of the connection between the first cable body and the second cable body, which is beneficial to protecting the cables and extending their service life. This arrangement further fixes the position of the cable connection through the clamping assembly, effectively avoids the occurrence of cable loosening, and improves the practicality of the device.

[0029] In summary: the utility model proposes a safety cable wired connector that prevents breakage, in which the first ring body 31, the second ring body 11 and the connecting slot plate 2 are all made of HPb59-1 brass material. HPb59-1 brass has good machinability, good mechanical properties, can withstand cold and hot pressure processing, is easy to weld, and has good corrosion resistance after surface nickel plating, thereby improving the anti-breakage performance of the cable wired connector; when the cable connector is needed for wiring, the first cable body 4 extends from the limiting component 3 into the clamping component 1, and the second cable body 5 extends from another set of limiting components 3 into the clamping component 1. Before connecting the cables, the limiting component 3 is first used to limit and stabilize the cables. Before the cable body passes through the first ring body 31, the two sets of pulling plates 38 are pulled toward the side away from the first ring body 31. The pulling plate 38 will drive the connecting plate 37 and the pull rod 36 to move toward the side away from the first ring body 31 at the same time.

At this time, the first cable body 4 and the second cable body 5 are between the two sets of clamping plates 12. After the cable cores of the first cable body 4 and the second cable body 5 are contacted and connected with each other, in order to further fix the connection between the two sets of cable bodies, the operator rotates the two sets of knobs 16, and the knobs 16 will drive the threaded rod 15 to rotate, and the screw rod 15 A bearing 14 is provided at one end of the threaded rod 15, and the threaded rod 15 pushes the clamping plate 12 on one side thereof to move toward the side close to the cable, until both sets of threaded rods 15 push both sets of clamping plates 12 to clamp tightly on the side of the cable connection, and then stop turning the knob 16. At this time, the two sets of insulating pads 13 are tightly wrapped around the periphery of the connection between the first cable body 4 and the second cable body 5, which is beneficial to protect the cable and prolong its service life. This setting further fixes the position of the cable connection through the clamping assembly 1, effectively avoiding the occurrence of loose cables and improving the practicality of the device. ;
