DETAILED DESCRIPTION

[0027] 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 herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] A cable connector provided by the present invention is used for completing the connection between a cable and a device.

[0029] See also Figure 1 and Figure 2 A cable connector includes a columnar shell 1, wherein a clamping component 11, a connecting component 12, an insulating component 13 and a locking component 14 are sequentially arranged inside the columnar shell 1 from left to right.

[0030] See also Figure 1-Figure 4The inside of the cylindrical shell 1 is provided with a circular groove 1 for passing the cable, a circular groove 2 15 for avoiding the clamping assembly 11, and a circular groove 3 16 for avoiding the connecting assembly 12, the insulating assembly 13 and the locking assembly 14 from left to right. The clamping assembly 11 includes an arc-shaped clamping plate 111 uniformly arranged in the circular groove 2 15 in the circumferential direction. A moving column 112 slidingly penetrating the cylindrical shell 1 is installed in the middle of the outer side of the arc-shaped clamping plate 111. A control member for controlling the moving column 112 to move radially along the cylindrical shell 1 is provided on the outer side of the cylindrical shell 1. The control member includes a cylindrical An annular groove 113 is provided at the position corresponding to the moving column 112 on the outer side of the shell 1, a collar 114 is threadedly installed on the annular groove 113, an inner ring 115 is embedded inside the collar 114, a connecting spring 116 sleeved on the outside of the moving column 112 is connected between the moving column 112 and the inner wall of the circular groove 15, a ball 117 is rollingly installed on the end of the moving column 112 away from the arc-shaped clamping plate 111, and an inner side of the inner ring 115 is provided with oblique grooves 118 which are evenly arranged in the circumferential direction and slideably cooperate with the corresponding ball 117, and the depth of the oblique grooves 118 gradually decreases along the circumference of the inner ring 115.

[0031] When the connector is connected to a cable, first, the protective layer on the right end of the cable needs to be stripped off to an appropriate length so that the multiple wires inside the cable are exposed. Then, the cable can be passed through the circular groove 1, the circular groove 2 15 and the circular groove 3 16 from left to right in sequence until the exposed wire end exceeds a certain length of the right end face of the cylindrical shell 1. At this time, the complete cable section is located between the circumferentially arranged arc clamping plates 111. Then, the collar 114 can be rotated around the annular groove 113. Since the collar 114 is threadedly connected to the annular groove 113, there is a certain connectivity between the collar 114 and the annular groove 113, and the collar 114 moves to the right while rotating around the annular groove 113, and the inner ring 115 moves synchronously with the collar 114 because the depth of the inclined groove 118 is along the inner ring The circumference of 115 gradually decreases, so during the rotation of the inner ring 115, the inner inclined groove 118 gradually contacts the ball 117 on the upper end of the moving column 112 and pushes the moving column 112, wherein the ball 117 helps to reduce the friction between the moving column 112 and the inclined groove 118. Under the cooperation of the inclined groove 118 and the ball 117, the moving column 112 drives the arc clamping plate 111 to move in the direction of the cable by compressing the connecting spring 116, and finally makes the circumferentially arranged arc clamping plates 111 synchronously clamp the cable to complete the fixation of the complete cable segment. In the initial state, the arc clamping plate 111 is in a state away from the cable under the cooperation of the moving column 112 and the connecting spring 116 to prevent the arc clamping plate 111 from interfering with the placement of the cable.

[0032] See also Figure 2 , Figure 3 , Figure 5 and Figure 6The connecting assembly 12 includes a connecting ring 121 arranged inside the circular groove three 16, a guide hole 123 evenly arranged in the circumferential direction is opened at the left end of the circular groove three 16, a guide column 122 corresponding to the guide hole 123 is installed at the left end of the connecting ring 121, a plug hole 124 is opened at the right end of the arc-shaped clamping plate 111, and a plug rod 125 evenly arranged in the circumferential direction and plugged with the corresponding plug hole 124 is installed at the left end of the connecting ring 121, the depth of the guide hole 123 is greater than the depth of the plug hole 124, and the length of the guide column 122 is greater than the length of the plug rod 125.

[0033] After the complete cable segment is fixed, the connecting ring 121 can be moved to the left and inserted into the circular groove 316, and the guide column 122 at the left end of the connecting ring 121 can be inserted into the corresponding guide hole 123. The cooperation between the guide column 122 and the guide hole 123 can not only guide the leftward movement of the connecting ring 121 but also limit the circumferential position of the connecting ring 121. At the same time, the insertion rod 125 at the left end of the connecting ring 121 is inserted into the corresponding insertion hole 124. The arc clamping plate 111 can be limited by the cooperation between the insertion rod 125 and the insertion hole 124, so as to prevent the ring 114 and the inner ring 115 from rotating due to external force factors, thereby reducing the clamping force of the arc clamping plate 111 clamping the cable, thereby further improving the relative stability between the clamping assembly 11 and the cable. Of course, in order to achieve quick one-time plug-in of the guide hole 123 and the guide column 122 when installing the connecting ring 121, a protrusion can also be set on the outside of the connecting ring 121 and a groove can be set on the inner wall of the circular groove 16, and the protrusion and the groove can be used to guide the insertion of the connecting ring 121.

[0034] See also Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 The insulating component 13 includes an annular rubber sleeve 131, a circular groove 4 matching the annular rubber sleeve 131 is provided at the right end of the connecting ring 121, an arc-shaped rubber plate 132 evenly arranged in the circumferential direction is installed inside the right end of the annular rubber sleeve 131, a fixing ring 133 located on the right side of the connecting ring 121 and threadedly connected to the inner wall of the circular groove 3 16 is provided on the outside of the annular rubber sleeve 131, a clamping member evenly arranged in the circumferential direction and used to clamp the annular rubber sleeve 131 is provided on the right end of the connecting ring 121, and the clamping member includes an arc-shaped clamping plate 134 hinged at the right end of the connecting ring 121 through a torsion spring shaft, an arc-shaped pressing plate 135 is installed on the right end of the arc-shaped clamping plate 134 close to the annular rubber sleeve 131, and the inner ring surface of the fixing ring 133 is inclined to the upper left.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8The locking assembly 14 includes a pressing ring 141 sleeved on the outside of the annular rubber sleeve 131, a guide ring 142 sleeved on the outside of the pressing ring 141 is installed at the right end of the fixed ring 133, and strip rods 143 evenly arranged in the circumferential direction are installed on the inner side of the guide ring 142. A strip groove 144 corresponding to the strip rod 143 is opened on the outside of the pressing ring 141, and a connector 145 is installed on the right end of the pressing ring 141. A rotating ring 146 is arranged on the outside of the connecting head 145. The rotating ring 146 is rotatably installed on the outside of the moving ring 147. The moving ring 147 is slidably connected to the connecting head 145 left and right through a spline. An annular thread groove 148 is opened on the right end of the cylindrical shell 1, and a threaded ring 149 threadedly matched with the annular thread groove 148 is installed on the left end of the rotating ring 146.

[0036] Next, the annular rubber sleeve 131 can be passed through the cable and the left end thereof can be inserted into the circular groove 4 at the right end of the connecting ring 121. In this process, the multiple wires at the right end of the cable can be passed through the corresponding arc-shaped rubber plate 132 and the annular rubber sleeve 131 one by one. The multiple wires can be flexibly separated and fixed by the cooperation between the arc-shaped rubber plate 132 and the annular rubber sleeve 131. At the same time, the fixing ring 133 can be moved to the left to be sleeved on the outside of the annular rubber sleeve 131, and the guide ring 142 moves synchronously with the fixing ring 133. Then, the guide ring 142 can be rotated to make the fixing ring 133 threadedly installed on the inner wall of the fixing groove 3, and at the same time, the fixing ring 1 33 presses against the connecting ring 121 to fix the connecting ring 121. During this process, the inner ring surface of the fixing ring 133 tilted toward the upper left gradually contacts the arc-shaped pressing plate 134 evenly arranged in the circumferential direction. The arc-shaped pressing plate 134 is pressed and synchronously drives the corresponding arc-shaped pressing plate 135 to rotate around the direction of the annular rubber sleeve 131 axially of the torsion spring. The arc-shaped pressing plate 135 presses against the wire in the annular rubber sleeve 131 by squeezing the annular rubber sleeve 131 to cause it to slightly deform. This can not only firmly fix the annular rubber sleeve 131 in the connecting ring 121, but also improve the overall stability between the multiple wires, thereby improving the overall stability and connectivity of the cable and the connector.

[0037] Subsequently, the excess wire can be cut off so that the right end of the wire is almost flush with the right end of the annular rubber sleeve 131, and then the connector 145 is moved to the left to move the pressing ring 141 between the guide ring 142 and the annular rubber sleeve 131, until the left end of the connector 145 is tightly against the right end of the annular rubber sleeve 131. During this process, the strip rod 143 and the strip groove 144 are correspondingly plugged and matched, which can not only guide the movement of the pressing ring 141, but also limit the circumferential position of the guide ring 142, effectively preventing the guide ring 142 from driving the fixed ring 133 to rotate. At this time, the moving ring 147, The rotating ring 146 and the threaded ring 149 are both located at the right end of the connector 145, and the threaded ring 149 is just located at the right end of the annular thread groove 148 of the cylindrical shell 1. Then the rotating ring 146 can be rotated around the movable ring 147, and the threaded ring 149 rotates synchronously therewith and gradually moves left and screws into the annular thread groove 148. The movable ring 147 moves to the left along the connector 145 synchronously with the rotating ring 146 through the spline fitting until the rotating ring 146 presses against the right end of the cylindrical shell 1, completing the connection between the connector 145 and the cylindrical shell, that is, completing the fixation between the cable and the connector.

[0038] With the threaded cooperation of the clamping component 11, the connecting component 12, the insulating component 13, the locking component 14 and the cylindrical shell 1 in sequence, the cable can be fixed in multiple stages from the inside to the outside, the cable has high firmness, and the overall stability and connectivity of the cable and the connector are greatly improved. The clamping component 11, the connecting component 12, the insulating component 13 and the locking component 14 can be connected and cooperated with each other to restrict and limit the position, further improving the overall stability, and can effectively prevent the cable from loosening or falling off when subjected to force.
