DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See also Figure 1 and Figure 2A novel coaxial cable includes a connecting portion 2 for firmly connecting two cable bodies 1, the connecting portion 2 includes a fixed connecting body 21 corresponding to the cable body 1 one by one and a movable connecting body 22 covered on the fixed connecting body 21 and corresponding to the fixed connecting body 21 one by one, the movable connecting bodies 22 are spirally connected together, and a non-return interlocking buckle assembly 23 is provided between the butt ends of the fixed connecting body 21 and between the other end and the corresponding movable connecting body 22, and the conductor 3 of the cable body 1 and the cable body 1 are crimped and fixed by the buckle assembly 23, and the two cable bodies 1 are firmly connected together to form a stable line, such as Figure 2 As shown, during the connection process, the fixed connector 21 and the corresponding movable connector 22 are first put on the corresponding cable body 1, the wire 3 passes through the fixed connector 21 and is twisted together, and then the movable connector 22 is threaded together, and in this process, the buckle components 23 at the opposite ends of the fixed connector 21 are automatically buckled together to crimp and fix the twisted wire 3. At the same time, the two fixed connectors 21 are connected together, and the buckle components 23 between the fixed connector 21 and the movable connector 22 automatically complete the buckle connection and then crimp and fix the corresponding cable body 1 respectively. The fixed connector 21 is fixed, and the fixed connector 21 is connected together again through the movable connector 22, and the buckle connection of the buckle assembly 23 at the twisted part of the wire 3 and the buckle connection on the cable body 1 are not performed at the same time, so that the crimping fixation at the twisted part of the wire 3 and the crimping fixation on the cable body 1 have relative independence, which can effectively reduce the influence of the crimping state changes of the two on each other, and effectively improve the stability and reliability of the cable connection as a whole. When the cable is connected, sealant is applied to the crimping part of the buckle assembly 23 on the cable body 1 to improve the overall sealing, wherein all structures of the connecting part 2 are insulating materials.

[0021] See also Figure 2 and Figure 4The buckle assembly 23 includes a lock head 231 and a lock seat 232 that are mutually embedded. The lock head 231 and the lock seat 232 have a certain elasticity. The lock head 231 in the buckle assembly 23 between the fixed connection body 21 and the corresponding movable connection body 22 is connected to the movable connection body 22, and the lock seat 232 is connected to the fixed connection body 21. The lock head 231 and the cable body are interference fit. When the fixed connection body 21 is sleeved on the corresponding cable body 1, the lock head 231 and the lock seat 232 are not buckled. At this time, due to the lock The head 231 has a certain elasticity and can be smoothly put on the cable body 1. Then, as the movable connecting body 22 is threadedly connected, the locking head 231 automatically passes through the locking seat 232 and is buckled together with the locking seat 232. At this time, the locking head 231 stably presses and fixes the cable body 1 under the restriction of the locking seat 232. The buckle component 23 at the twisted part of the wire 3 is similarly pressed and fixed. The size of the buckle component 23 will vary depending on the crimping object, but the principle of crimping and fixing is the same.

[0022] See also Figure 2 An intermediate connector 24 is provided between the fixed connector 21 and the corresponding movable connector 22. The intermediate connector 24 is fixedly connected to the fixed connector 21, and a stabilizing suppression component 25 is provided between the intermediate connector 24 and the movable connector 22. The stabilizing suppression component 25 controls the order of automatic clasping connection of the buckle component 23 on the one hand, so that the buckle component 23 at the twisted part of the wire 3 is firstly clasped to press and fix the twisted part of the wire 3, and then the buckle component 23 on the cable body 1 is clasped to crimp and fix the cable body 1, so as to avoid crimping and fixing the cable body 1 first to affect the twisted state of the wire 3, thereby facilitating the improvement of the stability and reliability of the cable connection. On the other hand, the movable connector 22 is further connected to the fixed connector 21 and the two movable connectors 22 to improve the stability of the overall connection.

[0023] See also Figure 2 and Figure 3The stable suppression component 25 includes a cavity 252 provided with a non-return suppression port 251 and a connector 254 movably inserted in the cavity 252 and provided with a clamp 253. The connector 254 corresponds to the corresponding intermediate connector 24, and the clamp 253 corresponds to the non-return suppression port 251. In the initial state, the clamp 253 is located on the inner side of the non-return suppression port 251. At this time, the non-return suppression port 251 has a suppression force on the clamp 253. During the threaded connection of the movable connector 22, the fixed connector 21 first moves with the movable connector 22. At this time, the suppression force of the non-return suppression port 251 on the clamp 253 is greater than the force required for the buckle connection of the buckle component 23 at the twisted part of the wire 3. , plays a suppressing role. Therefore, before the buckle assembly 23 completes the buckle connection to crimp and fix the twisted part of the wire 3, the clamp head 253 is always located on the inner side of the non-return inhibition port 251. Here, the inner side of the non-return inhibition port 251 is the side with a larger opening of the non-return inhibition port 251, and the outer side is the side with a smaller opening. When the buckle assembly 23 between the fixed connectors 21 automatically completes the buckle connection to crimp and fix the twisted part of the wire 3, the fixed connector 21 is in a fixed connection state. Then, as the movable connector 22 continues to move, the fixed connector 21 no longer moves therewith. At this time, the clamp head 253 will pass through the non-return inhibition port 251 and be located on the outer side of the non-return inhibition port 251. Figure 3 As shown, the non-return inhibition mouth 251 will prevent the clamp head 253 from moving back and play a non-return role and limit the clamp head 253 to form a limit connection, connecting the movable connecting body 22 with the fixed connecting body 21 and the two movable connecting bodies 22 together, further improving the stability of the overall connection. At the same time, the buckle assembly 23 between the fixed connecting body 21 and the movable connecting body 22 automatically completes the buckle connection, wherein the non-return inhibition mouth 251 has a certain elasticity. When the clamp head 253 passes through the non-return inhibition mouth 251, the non-return inhibition mouth 251 is deformed to allow the clamp head 253 to pass smoothly. After the clamp head 253 passes smoothly, the non-return inhibition mouth 251 is reset to limit the clamp head 253 and prevent it from moving back.

[0024] See also Figure 2 , Figure 3 and Figure 4The lock head 231, the lock seat 232, the cavity 252, the intermediate connector 24, the clamp 253 and the non-return inhibiting port 251 are all annular structures. The lock head 231 of the annular structure and the lock seat 232 are snap-connected to form a crimping fixing area of ​​the annular structure, which is conducive to further improving the stability and reliability of the cable connection. The cavity 252 of the annular structure and the intermediate connector 24 of the annular structure are conducive to improving the stability of the limited connection process between the fixed connector 21 and the movable connector 22, thereby improving the stability of the snap-on crimping process. The clamp 253 of the annular structure and the non-return inhibiting port 251 are also annular structures, which are further conducive to improving the stability of the limited connection, and are conducive to further improving the stability and reliability of the cable connection process and the connection state as a whole. Among them, the clamp 253 is in an arc shape, and the non-return inhibiting port 251 is a limiting eaves of a trumpet-shaped structure. When the clamp 253 passes through the non-return inhibiting port 251 from the inside to the outside, the non-return inhibiting port 251 limits the clamp 253 from both sides, thereby improving the stability and reliability of the limited connection and non-return.

[0025] See also Figure 2 and Figure 4 The lock head 231 is provided with a plurality of dividing grooves 233, which are evenly distributed along the circumference of the lock head 231 to divide the mutually embedded part of the lock head 231 and the lock seat 232 into a plurality of embedded units, such as Figure 4 As shown, on the basis of firmly crimping and fixing the cable body 1 and the twisted parts of the wires 3, the rigidity of the lock head 231 is reduced to a certain extent by dividing the grooves 233, so that the fixed connector 21 is smoothly mounted on the corresponding cable body 1, and at the same time, it is convenient for the firmly inhibiting component 25 to stably control the order of automatic buckling and crimping and fixing of the buckle component 23, so that the buckle component 23 at the twisted part of the wire 3 first completes the automatic buckle connection to crimp and fix the twisted part of the wire 3, and then the buckle component 23 on the cable body 1 completes the automatic buckle connection to crimp and fix the cable body 1, so as to avoid crimping and fixing the cable body 1 first to affect the twisted state of the wire 3, thereby facilitating improving the stability and reliability of the cable connection.

[0026] See also Figure 1 and Figure 2 The left intermediate connecting body 24 is only slidably connected with the left movable connecting body 22 at the axial upper limit position, and the left movable connecting body 22 is in a stationary state during the threaded connection process. The right intermediate connecting body 24 is slidably connected with the right movable connecting body 22 at the axial upper limit position and rotatably connected in the axial direction, and the right movable connecting body 22 is in a rotational feeding state during the threaded connection process. The left intermediate connecting body 24 is fixedly connected with a limiting member 26, and a limiting seat 27 is provided on the right intermediate connecting body 24. The limiting seat 27 only limits the limiting member 26 in the circumferential direction, such as Figure 2As shown, during the process of threaded connection of the movable connecting body 22, the movable connecting body 22 on the left side does not move, the intermediate connecting body 24 on the left side also rotates, and the movable connecting body 22 on the right side rotates, and in the threaded connection state, the movable connecting body 22 feeds to the left, and before the right movable connecting body 22 rotates, the limiting member 26 is inserted into the limiting seat 27, and the intermediate connecting body 24 on the left side is used to limit the intermediate connecting body 24 on the right side, so that the intermediate connecting body 24 on the right side does not rotate with the rotation of the right movable connecting body 22, but only feeds to the left, and the corresponding fixed connecting body 21 on the right side does not rotate with it, but only feeds to the right, which accordingly improves the stability of the automatic buckle connection process of the buckle assembly 23, wherein the lock head 231 connected to the right movable connecting body 22 is rotationally connected to the right movable connecting body 22, and when the lock head 231 is automatically buckled with the corresponding lock seat 232 during the feeding of the right movable connecting body 22, the lock head 231 can not rotate with the movable connecting body 22, which is conducive to improving the stability of the automatic buckle connection process.
