DETAILED DESCRIPTION

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples and cannot be used to limit the protection scope of the utility model.

[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0027] The cable connector locking mechanism of the utility model embodiment is as follows Figures 1 to 6 As shown, it comprises a mounting seat 1 and a connecting pipe 2 connected to the mounting seat 1. The mounting seat 1 has an installation cavity for installing the cable connector body; the connecting pipe 2 is provided with a locking assembly, and the locking assembly has a locking hook 30 suitable for cooperating with a locking groove 91 (preferably set as an annular groove) of the plug-in 9. When in use, the plug-in 9 (such as Figure 7 As shown in the figure, the plug-in 9 is inserted into the connecting tube 2 and the electrical conductor in the plug-in 9 is connected with the electrical conductor on the cable connector body to achieve electrical connection. Preferably, a stopper surface facing the connecting tube 2 is provided on the mounting seat 1, and the plug-in 3 is limited by contacting with the stopper surface when it is inserted into the connecting tube 2.

[0028] In order to ensure the locking effect of the plug-in 9, there are four locking assemblies in this embodiment, and the four locking assemblies are evenly distributed along the circumference. In actual operation, the number of the locking assemblies can also be set to two, three or five, and three to four are the best. These locking assemblies are evenly distributed along the circumference on the side wall of the connecting pipe 2 to ensure uniform locking of the plug-in 9 and ensure the stability of the connection.

[0029] In order to adapt to the installation of the locking assembly, an installation groove 20 is provided on the side wall of the connecting pipe 2 corresponding to each locking assembly, and the locking assembly is installed in the installation groove 20. The locking assembly includes a movable locking strip 3 and an elastic member 4. The locking hook 30 is arranged on the movable locking strip 3. Under normal circumstances, the elastic member 4 provides elastic force for the movable locking strip 3 to make the locking hook 30 extend into the tube cavity of the connecting pipe 2. A sleeve 5 is rotatably mounted on the outside of the connecting pipe 2, and the locking assembly is on the inside of the sleeve 5. A driving part is provided on the inside of the sleeve 5 corresponding to each movable locking strip 3. When the sleeve 5 is rotated, the driving part applies pressure to the movable locking strip 3 to control the movement of the movable locking strip 3, thereby making the locking hook 30 move outward and withdraw from the tube cavity of the connecting pipe 2, so that the plug-in 9 can be unlocked, thereby pulling the plug-in 9 out of the connecting pipe 2.

[0030] The structure of the locking mechanism in this embodiment has been optimized, the number of components has been significantly reduced, the structure is simple, and it is beneficial to reduce production costs and improve production efficiency; when the plug-in 9 is connected to the cable connector, the plug-in 9 is inserted into the lumen of the connecting tube 2. During the insertion process, the plug-in 9 pushes the locking hook 30 to avoid movement outside the lumen of the connecting tube 2. When the plug-in 9 and the connecting tube 2 are plugged into place, the locking hook 30 is inserted into the locking groove 91 of the plug-in 9 to lock the plug-in 9. When unlocking, the driving part generates a force on the movable locking strip 3 by rotating the sleeve 5, and then the locking hook 30 moves outside the lumen of the connecting tube 2, so that the locking of the plug-in 9 by the locking hook 30 can be released, so that the plug-in 9 can be separated from the cable connector, and the entire locking and unlocking operation process is smooth. Therefore, after the structural optimization in this application, the locking and unlocking operation of the locking mechanism is very convenient, which can improve the user experience.

[0031] like Figure 1 and Figure 2As shown, the middle part of the movable locking strip 3 is rotatably arranged in the mounting groove 20 through the mounting pin 6, one end of the movable locking strip 3 is a locking end 31, and the other end is a handle end 32; the locking hook 30 is arranged on the inner side of the locking end 31 and protrudes in the direction of the connecting tube 2; the elastic member 4 is arranged between the handle end 32 and the connecting tube 2, and the elastic member 4 provides an outward elastic force for the handle end 32 to keep the locking end 31 moving inwardly, and the driving part is a driving inclined surface 51 corresponding to each handle end 32, which is arranged in the rotatable direction of the sleeve 5. The height of the driving slope 51 upward is gradually set, so that when the sleeve 5 is at different angles, the driving slope 51 generates different forces on the handle end 32. When the sleeve 5 rotates, the driving slope 51 pushes the handle end 32 to move inward, thereby causing the locking end 31 to move out of the lumen of the connecting tube 2 to achieve unlocking; after the sleeve 5 is rotated and reset, the driving slope 51 removes the pressure on the handle end 32, so that the elastic member 4 applies an outward force to the handle end 32 to cause the locking end 31 to move toward the lumen of the connecting tube 2.

[0032] In order to limit the rotation angle of the sleeve 5 relative to the connecting pipe 2 , an angle limiting structure is further provided between the connecting pipe 2 and the sleeve 5 to limit the relative rotation angle between the connecting pipe 2 and the sleeve 5 .

[0033] For details, see Figure 1 As shown, the angle limiting structure includes a strip hole 7 and a limiting pin 8, the strip hole 7 is provided on the connecting pipe 2, the limiting pin 8 is provided on the sleeve 5, and the strip hole 7 is provided along the rotation direction of the sleeve 5, so that when the sleeve 5 rotates, the limiting pin 8 rotates in the strip hole 7, and when the limiting pin 8 abuts against the end of the strip hole 7, the sleeve 5 can no longer continue to rotate relative to the connecting pipe 2, thereby achieving the purpose of limiting the rotation angle of the sleeve 5. As a modified implementation scheme, the strip hole 7 can be provided on the sleeve 5, and the limiting pin 8 can be fixed on the connecting pipe 2 accordingly. The limiting pin 8 and the sleeve 5 / connecting pipe 2 can be fixedly connected by riveting, welding, etc. As a preferred solution, by setting the inclination angle of the driving inclined surface 51, the rotatable angle of the sleeve 5 relative to the connecting pipe 2 is controlled to be 20 degrees to 45 degrees, such as 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees or 45 degrees, so that the sleeve 5 can be rotated within this angle range to achieve unlocking. In this way, the problem of easy mislocking caused by the sleeve 5 rotating at too small an angle can be avoided, and the problem of inconvenience in unlocking caused by the sleeve 5 rotating at too large an angle can be avoided, thereby improving the convenience of operation.

[0034] See also Figures 4 to 6As shown, a limiting groove 52 is provided on the inner wall of the sleeve 5 corresponding to each handle end 32, the driving inclined surface 51 is provided on a side wall of the limiting groove 52, and a stop surface 53 opposite to the driving inclined surface 51 is provided in the limiting groove 52, and the angle between the driving inclined surface 51 and the stop surface 53 is an acute angle. Since the driving inclined surface 51 is inclined with a gradually changing height, when the active locking strip 3 is in a normal state (the state in which the locking hook 30 extends into the lumen of the connecting tube 2), the handle end 32 is at the bottom of the limiting groove 52 and the side surface of the handle end 32 abuts against the stop surface 53 (as shown in FIG. Figure 5 , Figure 6 When the sleeve 5 is rotated, the driving inclined surface 51 gradually applies pressure to the pressing handle end 32, and the locking end 31 is driven to rotate outward by the lever principle, so that the locking hook 30 moves outside the lumen of the connecting tube 2 to perform an unlocking action. After the unlocking is completed, the sleeve 5 is released, and the sleeve 5 can be automatically rotated and reset under the reverse force of the pressing handle end 32 on the driving inclined surface 51.

[0035] In order to facilitate assembly and provide stable elastic force through the elastic member 4, it is preferred to set the locking end 31 farther away from the mounting seat 1 relative to the handle end 32, and the elastic member 4 is set as a tower spring. A positioning groove 21 opposite to the handle end 32 is provided in the mounting groove 20, and the end of the tower spring with a larger diameter extends into the positioning groove 21, and a positioning column 33 is provided at the end of the handle end 32 facing the mounting groove 20, and the end of the tower spring with a smaller diameter is tightly fitted on the positioning column 33. During assembly, the small end of the tower spring can be tightly fitted on the positioning column 33 first, and then the installation The mounting pin 6 positions the movable locking bar 3 in the mounting groove 20. In this state, the movable locking bar 3 is in a rotatable state and due to the presence of the tower spring, the handle end 32 protrudes more outward relative to the locking end 31. The sleeve 5 is then sleeved on the outside of the connecting tube 2. During the sleeve 5 installation process, the inner wall of the sleeve 5 squeezes the handle end 32 to move inward until it is installed in place. When it is installed in place, the large end of the tower spring extends into the positioning groove 21. The positioning groove 21 can position the large end of the tower spring to prevent the tower spring from shifting, thereby allowing the tower spring to maintain a stable elastic force for the movable locking bar 3.

[0036] like Figure 2 and Figure 6 As shown, in order to increase the installation space of the tower spring, the handle end 32 is provided with an annular groove 34 surrounding the positioning column 33 , and the end of the tower spring with a smaller diameter extends into the annular groove 34 and is tightly matched with the positioning column 33 .

[0037] In order to facilitate the assembly of the mounting seat 1 and the connecting pipe 2, the mounting seat 1 is provided with an interface for one end of the connecting pipe 2 to extend into, and a clamping block 11 protruding inward is provided at the interface, the end of the connecting pipe 2 extends into the interface, and a clamping groove 22 engaged with the clamping block 11 is provided on the outer wall of the connecting pipe 2; the connecting pipe 2 is composed of two semi-annular mounting blocks 12 radially coupled and connected, and in this way, when the mounting blocks 12 are coupled to form the mounting seat 1 during assembly, the clamping block 11 and the clamping groove 22 form a clamping fit to achieve the connection between the mounting seat 1 and the connecting pipe 2; the two mounting blocks 12 can be fixedly connected by screws, or fixedly connected by welding.

[0038] As a further optimization, in order to lock the sleeve 5, a through screw hole 54 is provided on the sleeve 5, and a corresponding positioning hole 23 is provided on the connecting tube 2. A locking screw (not shown in the figure) is threaded in the screw hole 54. When the locking screw is tightened, its inner end extends into the positioning hole 23 to limit the rotation of the sleeve 5 relative to the connecting tube 2. When the restriction on the sleeve 5 is released, it is only necessary to rotate the locking screw in the opposite direction to make the inner end of the locking screw withdraw from the positioning hole 23. The restriction can be set when the movable locking bar 3 is in a locked state (that is, the locking hook 30 extends into the tube cavity of the connecting tube 2). In this way, when the movable locking bar 3 is in a locked state, the positioning hole 23 is aligned with the screw hole 54, and the movable locking bar 3 can be prevented from being unlocked by limiting the rotation of the sleeve 5, thereby preventing it from being misunderstood as locked by others.

[0039] In order to make the interference fit between the handle end 32 and the driving inclined surface 51 smoother, it is preferred to set the upper portion of the handle end 32 to be an upwardly convex arc surface.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
