DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0040] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1, reference Figure 1 and Figure 2 , this embodiment provides a cable installation junction box.

[0042] The cable installation junction box comprises a junction mechanism 100 and an auxiliary mechanism 200 .

[0043] Specifically, the wiring mechanism 100 includes a box body with an open top, a cover plate 102 is detachably installed on the top of the box body, and a terminal 103 for connecting to a cable is installed inside the box body, and a plurality of jacks 104 are arranged in a horizontal array on the outer side of the terminal 103, and threading holes 105 corresponding to the jacks 104 are arranged in a horizontal array on the outer side wall of the box body, and each threading hole 105 is also provided with a conduit 106 for guiding the insert tube 201 on the outer periphery of the inner side of the box body.

[0044] The auxiliary mechanism 200 includes an insertion tube 201 disposed inside the threading hole 105 .

[0045] Furthermore, a guide rib 106a is provided on the inner wall of the conduit 106, and a guide groove 201a is provided on the outer surface of the plug 201. The guide rib 106a and the guide groove 201a are slidably matched, so that the plug 201 can slide along the guide rib 106a toward the conduit 106. When the cable is inserted into the plug 201, the cable and the plug 201 can move synchronously along the conduit 106 to enter the socket 104 outside the terminal 103, thereby completing the connection between the cable and the socket 104.

[0046] Example 2, reference Figure 1-Figure 4 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0047] The auxiliary mechanism 200 further comprises a control member 202 mounted on the inner side of one end of the cannula 201 , a transmission member 203 is movably embedded in the inner side of the control member 202 , and a clamping member 204 is also provided on the outer side of the transmission member 203 .

[0048] Furthermore, the control member 202 includes a control ring 202a embedded in the inner side of the cannula 201, a rotating sleeve 202b is integrally connected to the end surface of the control ring 202a, and an inclined pushing edge 202c is integrally provided on the interior of the rotating sleeve 202b.

[0049] The transmission member 203 includes a movable sleeve 203a having an outer diameter the same as the inner diameter of the insert tube 201, and a limiting groove 203b and a push groove 203c are sequentially arranged on the outer wall of the movable sleeve 203a, and the limiting groove 203b is slidably matched with the limiting edge 201b of the inner wall of the insert tube 201, so that the rotation of the movable sleeve 203a can be limited by the cooperation between the limiting edge 201b and the limiting groove 203b, so that the movable sleeve 203a can only move horizontally along its axial direction, and at the same time, an inner ring 203d is coaxially fixedly arranged on the inner wall of the movable sleeve 203a close to the clamping member 204.

[0050] The clamping member 204 includes a fixing ring 204a fixedly disposed on the inner wall of the insertion tube 201, and a deformable clip 204b is fixed on the end surface of the fixing ring 204a.

[0051] Furthermore, the push groove 203c is arranged at an angle, and the push groove 203c and the push edge 202c are arranged to cooperate with each other. Therefore, under the mutual cooperation between the push groove 203c and the push edge 202c, when the user rotates the rotating sleeve 202b counterclockwise through the control ring 202a, the push force of the push edge 202c on the groove wall of the push groove 203c can be exerted on the movable sleeve 203a which is restricted in rotation and moves along the axial direction of the insert tube 201, thereby realizing the cooperation between the inner ring 203d and the clamping member 204.

[0052] Preferably, the clip 204b is arranged in an inclined trapezoidal shape and is arranged in a ring array on the fixed ring 204a. The front ends of the multiple clips 204b can cooperate to form a circular channel for the cable to pass through. At the same time, each clip 204b can be deformed to a certain extent. Therefore, when the inner ring 203d moves toward the clip 204b with the translation of the movable sleeve 203a, the multiple clips 204b can be bent toward the axial direction of the tube 201 at the same time under the push of the translation of the inner ring 203d, so that the size of the channel formed by the front ends of the multiple clips 204b can be changed, thereby meeting the needs of fixing and clamping cables of different diameters and improving the adaptability of the clamping member 204.

[0053] When in use, after inserting the cable into the insertion tube 201 and adjusting the insertion length of the cable, the control ring 202a is rotated counterclockwise to squeeze the clamping piece 204b through the inner ring 203d on the movable sleeve 203a, so that the front ends of multiple clamping pieces 204b are simultaneously retracted inward and abut against the outside of the cable to complete the clamping and fixing of the cable. At this time, the cable can be sent to the junction box through the insertion tube 201 to complete the connection. Through the matching setting of the clamping piece 204 and the control piece 202, the clamping size of the clamping piece 204 can be adaptively adjusted according to the diameter of the cable to meet the plug-in needs of different cables. At the same time, by clamping and fixing the cable, the smooth delivery of the cable can be guaranteed to avoid bending and deformation of the front end of the cable when it is delivered, which affects the smooth plug-in between it and the terminal 103.

[0054] Example 3, reference Figure 1-Figure 7 , which is the third embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0055] The terminal mechanism 100 further includes a main magnet 107 mounted on the periphery of each terminal 103 .

[0056] The auxiliary mechanism 200 also includes a blocking member 205 fixed to the inner side of the other end of the cannula 201, a magnetic member 206 is arranged on the inner side of the blocking member 205, and a traction member 207 is installed on the outer side of the magnetic member 206, and a flip member 208 is rotatably installed on one end of the traction member 207, and a connecting member 209 is fixedly installed on the other end of the traction member 207.

[0057] Specifically, the blocking member 205 includes a spacer ring 205a arranged on the inner wall of the tube 201, an opening 205b is left on the spacer ring 205a, and a blocking opening 205c is left on the outer side of the opening 205b, and multiple openings 205b and blocking openings 205c are opened in a circular array on the spacer ring 205a, and a magnetic member 206 is installed inside each opening 205b.

[0058] The magnetic member 206 includes a flap 206a located inside the opening 205b, and a positive magnetic piece 206b and a negative magnetic piece 206c are fixedly provided on the two side surfaces of the flap 206a. It should be noted that the positive magnetic piece 206b and the main magnet 107 are arranged with the same poles, while the negative magnetic piece 206c and the main magnet 107 are arranged with opposite poles. Therefore, when the main magnet 107 and the positive magnetic piece 206b are opposite to each other, there is a repulsive force between the two, so that the insert 201 is located at the outermost side of the box body, and when the main magnet 107 and the negative magnetic piece 206c are opposite to each other, there is an attractive effect between the two, so that the insert 201 can move toward the terminal 103 under the action of the suction force.

[0059] The traction member 207 includes a positioning strip 207a fixed on the surface of the spacer ring 205a, a positioning head 207b is arranged at the end of the positioning strip 207a, a traction rod 207c is arranged outside the positioning head 207b, a positioning groove 207d matching with the positioning head 207b is reserved on the outer side of the traction rod 207c, and the positioning head 207b is embedded in the positioning groove 207d, so that under the sliding cooperation between the positioning groove 207d and the positioning head 207b, the traction rod 207c and the positioning strip 207a can be stably connected, and the traction rod 207c can move with the movable sleeve 203a.

[0060] The flip member 208 includes a clamp 208a arranged on the outside of the flap 206a, the clamp 208a can clamp and lock the flap 206a, and the outside of the clamp 208a is coaxially fixedly connected to the lever 208b, and the outside of the lever 208b is also coaxially provided with a connecting rod 208c, that is, the flap 206a, the clamp 208a, the lever 208b and the connecting rod 208c can rotate synchronously, and at the same time, a traction spring 208d is also connected to the outer end of the connecting rod 208c, and the other end of the traction spring 208d is connected to the bottom of the traction rod 207c, and the outer end of the connecting rod 208c and the traction rod 207c are staggered, that is, the traction spring 208d respectively connected to the two is inclined, so that when the connecting rod 208c rotates, the traction spring 208d is deformed, and the elastic force of the traction spring 208d can assist the rotation of the connecting rod 208c.

[0061] The connecting member 209 includes a fixing rod 209a fixedly arranged inside the movable sleeve 203a, a bayonet 209b is arranged at the end of the fixing rod 209a, a return block 209c is arranged inside the bayonet 209b, and the return block 209c is fixed to the end of the traction rod 207c.

[0062] Furthermore, the lever 208b is V-shaped, and both ends thereof are rounded arc-shaped. The movement path of one end of the lever 208b corresponds to one side of the blocking opening 205c, so that when the lever 208b performs reciprocating translational motion with the traction rod 207c, the end of the lever 208b that cooperates with the blocking opening 205c can gradually contact the outer edge of the blocking opening 205c, and then, under the obstruction of the blocking opening 205c, the lever 208b is prompted to rotate more than 90°, so that the flap 206a, the clamp 208a and the connecting plate are turned over synchronously, and when the three are turned over, the traction spring 208d is pulled and stretched. When the flap 206a turns to 90° with the lever 208b, the connecting rod 208c coincides with the traction rod 207c, and the traction spring At this time, 208d is in a coaxial state with the traction rod 207c, and the traction spring 208d is at its maximum stretching value. As the lever 208b is further flipped, the distance between the end of the connecting rod 208c and the end of the traction rod 207c begins to decrease, and the traction spring 208d begins to shrink at this time, and the traction spring 208d can drive the flap 206a to rotate until the traction spring 208d recovers its original length. Therefore, through the cooperation of the lever 208b and the blocking port 205c and the traction of the traction spring 208d, the flap 206a can be flipped 180°, realizing the change of the position state of the positive magnetic piece 206b and the negative magnetic piece 206c relative to the main magnet 107, thereby achieving the purpose of regulating the repulsive or attractive force between the terminal 103 and the plug 201, which is convenient for the plugging and unplugging of the cable during operation.

[0063] The return block 209c is a deformable setting, and the return block 209c and the bayonet 209b are snap-fitted. The return block 209c is fixed to one end of the traction rod 207c, so that when the return block 209c fixed to the end of the traction rod 207c is located inside the bayonet 209b, the traction rod 207c can move synchronously with the movable sleeve 203a, thereby realizing the control of the traction rod 207c and the clamping piece 204b through the movement of the movable sleeve 203a, and when the positioning head 207b moves to the end of the positioning groove 207d relatively with the movement of the traction rod 207c, the flap 206a is flipped over, and the traction rod 207c no longer moves, then the deformable setting of the return block 209c can be realized. , so that the engagement between the return block 209c and the bayonet 209b is disengaged, that is, the return block 209c is separated from the bayonet 209b, and the bayonet 209b part continues to move with the movable sleeve 203a, thereby realizing the separate control of the clamping member 204. When the movable sleeve 203a is reset, the bayonet 209b can still squeeze and push the return block 209c to realize the reset movement of the traction rod 207c and make the return block 209c return to the inside of the bayonet 209b again. Through the split setting of the connecting member 209, while satisfying the traction control of the traction member 207 by the movable sleeve 203a, it does not affect the control of the clamping member 204 by the movable sleeve 203a, thereby ensuring the normal use of the flipping regulation function and the clamping function.

[0064] When connecting the cable, first insert the cable into the corresponding plug 201 and adjust the appropriate insertion length, then rotate the control ring 202a counterclockwise, and the rotating sleeve 202b drives the movable sleeve 203a to move horizontally. At this time, the movement of the movable sleeve 203a drives the traction rod 207c to translate and deflect the flap 206a. The side of the flap 206a opposite to the main magnet 107 is flipped from the positive magnetic piece 206b to the negative magnetic piece 206c, so that the repulsive force between the plug 201 and the terminal 103 is converted into an attractive force. At this time, first grab the plug 201, and after the clamping piece 204b is retracted to complete the fixation of the cable, release the plug 201. The plug 201 can drive the cable to move toward the terminal 103 under the action of the magnetic attraction, so that the cable plug end is fully extended into the terminal 103 to complete the connection, ensuring the connection between the cable and the terminal 103 The cable is in position, and if it is necessary to pull out the cable, the control ring 202a is reversed to convert the magnetic force between the plug 201 and the terminal 103 into a repulsive force. At this time, the cable can be ejected with the plug 201 under the action of the repulsive magnetic force. The transmission member 203 transmits the clamping member 204 and the magnetic member 206 respectively, and the rotating control member 202 can realize the synchronous control of the clamping member 204, the magnetic member 206 and the traction member 207. It can clamp and loosen cables of different diameters and realize automatic insertion and extraction of cables, thereby improving the adaptability of the junction box to different cables. At the same time, with the assistance of magnetic force, virtual connection between the cable and the junction box can be avoided, thereby ensuring the subsequent stable transmission and use of the cable. While ensuring the stable connection between the cable and the junction box, it also makes the connection between the cable and the junction box more convenient and efficient.
