The invention provides a cable fixing head, which comprises a first tightening nut 11, a first sealing ring 12 positioned in the first tightening nut 11 and a first main body 13 matched with the first tightening nut 11 to axially clamp the first sealing ring 12; and the device further comprises a second tightening nut 14, a second sealing ring 15 positioned in the second tightening nut 14 and a second main body 16 matched with the second tightening nut 14 to axially clamp the second sealing ring 15, wherein the second tightening nut 14 is arranged on the first main body 13 and is in sealing connection.
The first tightening nut 11 has an internal thread extending inwardly from the one end port, and the first body 13 has an external thread that mates with the internal thread of the first tightening nut 11.
The second tightening nut 14 also has internal threads and the second body 16 has external threads that mate with the internal threads of the second tightening nut 14.
The first sealing ring 12 is fitted inwardly into the first packing nut 11 from a port having an internal thread.
The second sealing ring 15 is fitted inwardly into the second packing nut 14 from a port having an internal thread.
The second tightening nut 14 is connected with the first main body 13, and the joint between the second tightening nut and the first main body maintains tightness so as to prevent water and dust.
Thus, when the cable with the inner insulating layer and the outer insulating layer penetrates into the cable fixing head, the first forcing nut 11 is screwed on the first main body 13, so that the first sealing ring 12 is tightly pressed, the outer insulating layer of the cable is tightly clamped, and the effects of clamping the outer insulating layer and preventing water and dust once are achieved; the second tightening nut 14 tightens the second main body 16, thereby compacting the second sealing ring 15, and achieving the effects of clamping the inner insulating layer and secondary waterproof and dustproof. Therefore, the cable fixing head provided by the invention can simultaneously clamp the inner insulating layer and the outer insulating layer of the cable, so that the dual waterproof and dustproof effects are realized, the waterproof and dustproof effects of the product are further improved, and the use safety performance of the product is improved.
The first tightening nut 11 and the first body 13 are connected through threads, and the first sealing ring 12 is compressed in the axial direction, so that the first sealing ring 12 is tensioned in the radial direction, the sealing effect is achieved, and similarly, the second tightening nut 14 and the second body 16 are also connected through threads, so that the radial tensioning of the second sealing ring 15 is achieved. Of course, the function of the sealing ring can also be achieved by other connection means than screw connection.
In order to make the structure simple and easy to install, in a specific embodiment, the second tightening nut 14 is connected with the shaft hole of the first body 13 in a clearance fit manner. The first body 13 is provided with a first stepped hole 132, and the end of the second tightening nut 14 remote from the internal thread is provided with a shaft 142, the shaft 142 is in clearance fit with the first stepped hole 132, and the shaft 142 is rotatable relative to the first stepped hole 132, so that the second tightening nut 14 rotates relative to the first body 13 when the second tightening nut 14 is tightened.
Considering that there is a relative rotation between the second tightening nut 14 and the first body 13 due to the clearance fit between the two, when the second tightening nut 14 is tightened, in order to prevent the second tightening nut 14 from moving axially relative to the first body 13 and separating from the first stepped hole 132 of the first body 13, in a specific embodiment, the shaft 142 of the second tightening nut 14 is provided with a first groove 143, and a clamp spring 19 for preventing the first body 13 and the second tightening nut 14 from axially loosening is disposed in the first groove 143, and the structure of the clamp spring 19 is shown in fig. 5. When the cable fixing head is installed, when the shaft 142 of the second tightening nut 14 passes through the first step hole 132 of the first main body 13, the clamp spring 19 is clamped into the first groove 143 of the shaft 142, and the clamp spring 19 is matched with the first groove 143 to play a role in preventing the shaft 142 from axially moving relative to the first step hole 132, so that the second tightening nut 14 and the first main body 13 are prevented from axially loosening.
In addition, in order to ensure the tightness of the gap fit connection between the shaft hole of the second tightening nut 14 and the shaft hole of the first main body 13, and achieve the waterproof and dustproof effects, in a specific embodiment, the shaft 142 of the second tightening nut 14 is provided with a second groove 144, and an O-ring for sealing the connection between the first main body 13 and the second tightening nut 14 is installed in the second groove 144, and when the shaft 142 of the second tightening nut 14 passes through the first stepped hole 132 of the first main body 13, the second groove 144 and the first stepped hole 132 cooperate to compress the O-ring, so that the second tightening nut 14 and the first main body 13 form a tight connection, and achieve the waterproof and dustproof purposes. In order to make the sealing effect between the second tightening nut 14 and the first body 13 better, the number of O-rings may be two, that is, the first O-ring 20 and the second O-ring 21, and the first O-ring 20 and the second O-ring 21 are arranged closely, so that the double O-rings can increase the friction coefficient and the compression degree, and make the sealing effect better.
Considering that in the installation process of the cable fixing head, when the fixing head at one end of the cable is screwed, the cable fixing head at the other end of the cable is screwed again, the cable outer insulating layer is driven to rotate together, so that the cable outer insulating layer is twisted and deformed due to the fixing of one end and the rotation of one end, thereby affecting the service life of the cable outer insulating layer and the safety performance of the product in use, in one specific embodiment, in order to achieve the rotatable limiting of the cable fixing head, the first main body 13 is specifically provided with a first circumferential key groove 131, the second tightening nut 14 is provided with a second circumferential key groove 141, and the first key groove 131 and the second key groove 141 are rotatably connected through a positioning key.
The positioning key can be matched with the first key groove 131 to rotate by a certain angle relatively, and the positioning key can also be matched with the second key groove 141 to rotate by a certain angle relatively, so that limiting of a certain angle is realized. The certain angle is determined according to the key groove angle of each of the first key groove 131 and the second key groove 141. In a specific embodiment, the sum of the rotatable angle of the first key slot 131 and the rotatable angle of the second key slot 141 and the rotatable angle of the positioning key is greater than 360 °, so that a better rotatable limiting effect can be achieved.
In one embodiment, the sum of the rotatable angle of the first key slot 131 and the rotatable angle of the second key slot 141 and the rotatable angle of the positioning key is 380 °, and the engineering test shows that the engineering application effect is better.
Because after the cable fixing head at one end of the cable is installed, that is, the first tightening nut 11 is tightened to clamp one end of the first main body 13 on the cable outer insulating layer, and the second tightening nut 14 is tightened to clamp the inner insulating layer at the same end of the cable, when the cable fixing head at the other end of the cable is tightened again, the first tightening nut 11 of the other cable fixing head drives the cable outer insulating layer to rotate when the first main body 13 is tightened, at this time, because the first key groove 131 and the second key groove 141 of the installed cable fixing head cooperate with the positioning key to enable the cable fixing head to realize 380-DEG rotatable limit, the cable outer insulating layer rotates along with the tightening, thereby avoiding distortion caused by rotation of the other end along with the tightening because one end of the cable outer insulating layer is fixed. Therefore, the service life of the cable outer insulation layer and the safety performance of the product in use are improved.
In another embodiment, the first keyway 131 and the locating key cooperate to rotate at an angle of 177.8 ° and the second keyway 141 and the locating key cooperate to rotate at an angle of 202.2 °. Engineering experiments further show that such an angle is the optimal angle.
In view of the fact that a certain shear force is generated to the outer insulation layer of the cable when the first tightening nut 11 is tightened to the first body 13, in one embodiment the cable fixing head further comprises a tightening screw 17 for cooperation with the inner wall of the cable outer insulation layer and an insulation sleeve 18 for preventing the tightening screw 17 from contacting the first body 13, the end of the tightening screw 17 being provided with a step surface 171 for cooperation with an inner recess 181 of the insulation sleeve 18.
In the installation process of the cable fixing head, after the cable passes through the first tightening nut 11 and the first sealing ring 12, the tightening screw 17 is screwed into the inner wall of the cable outer insulating layer matched with the tightening screw 17, so that the bearable tension of the cable outer insulating layer is increased, and therefore, when the first tightening nut 11 is screwed into the first main body 13, the cable outer insulating layer can be prevented from being pulled off, so that the cable positioned in the cable outer insulating layer is protected, and the safety performance of a product is improved. And the end face incision department of cable outer insulating layer very produces the burr easily, after the inner wall of fastening screw 17 screw in with the cable outer insulating layer of fastening screw 17 matched with, the terminal surface of fastening screw can also block the burr of the end face incision department of cable outer insulating layer, has still further increased the security performance of product.
In addition, the end step surface 171 of the fastening screw 17 is matched with the inner groove 181 of the insulating sleeve 18, so that the fastening screw is prevented from contacting the first main body 13 made of metal, the insulating effect is achieved, and the safety performance of the product is also improved.
Considering that when the inner diameter of the threading hole 111 at the end of the first tightening nut 11 remote from the internal thread is larger than the outer diameter of the end 172 of the tightening screw 17, it is possible to carry out the tightening screw 17 when pulling out the cable, and therefore, in one embodiment, the maximum outer diameter of the end 172 of the tightening screw 17 is larger than the maximum inner diameter of the threading hole 111 of the first tightening nut 11. In this way, the tightening screw can be restrained in the axial direction to prevent the tightening screw 17 from being carried out when the cable is pulled out.
In addition, to facilitate installation of the fastening screw 17, the bottom intermediate counterbore 173 of the fastening screw 17 may be a hexagonal counterbore. Therefore, the fastening screw 17 is conveniently screwed into the inner wall of the cable outer insulating layer matched with the fastening screw 17 by using the hexagonal wrench, so that the assembly efficiency of a product is improved, and the assembly cost of the product is reduced.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
