[0026] Example 1

[0027] Reference Figure 1-Figure 4 , which is the first embodiment of the utility model, and this embodiment provides a transformer cable terminal, which includes a main body component 100 and a locking component 200, and the locking component 200 is used to facilitate the fixation of the cone support 103.

[0028] Specifically, the main body component 100 includes a cable 101 , an epoxy sleeve 102 and a cone support 103 . The epoxy sleeve 102 is located outside the cable 101 , and the cone support 103 is disposed inside the epoxy sleeve 102 .

[0029] The epoxy sleeve 102 is used to fix and protect the insulating part of the cable 101, and the cone support 103 supports and fixes the conductive part of the cable 101. This is the prior art and will not be described in detail in this solution. A part of the cone support 103 is located inside the epoxy sleeve 102.

[0030] Specifically, the locking assembly 200 is arranged on one side of the cone support 103, and includes a locking member 201, a pushing member 202 and a reset member 203. The locking member 201 is arranged on one side of the cone support 103, the pushing member 202 is located on one side of the locking member 201, and the reset member 203 is arranged on one side of the locking member 201.

[0031] The locking member 201 is provided to lock and fix the cone support 103, and during the fixing process, the cone support 103 can be subjected to force in a circle at the same time, so as to avoid the cone support 103 from tilting due to uneven force when fixed, and can reduce installation time and labor costs when fixed. The pushing member 202 is provided to drive the locking member 201 to move, so that the locking member 201 can lock and fix the cone support 103. When the cone support 103 needs to be disassembled, the pushing member 202 is separated from the locking member 201, and then the locking member 201 can be driven to reset by the resetting member 203, so that the locking member 201 can release the restriction on the cone support 103, and then the cone support 103 can be disassembled.

[0032] Example 2

[0033] Reference Figure 1-Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the locking member 201 includes a positioning column 201a, a rotating ring 201b and an extrusion strip 201c. The positioning column 201a is fixed to one side of the epoxy sleeve 102, the rotating ring 201b is located on one side of the cone support 103, the extrusion strip 201c is fixed to one side of the rotating ring 201b, and a slot 201a-1 corresponding to the extrusion strip 201c is opened on the positioning column 201a.

[0035] There are multiple positioning posts 201a, which are evenly distributed in a ring shape on one side of the epoxy sleeve 102. The number of extrusion strips 201c is the same as that of the positioning posts 201a. The extrusion strips 201c are inclined, with one end close to the slot 201a-1 and the other end close to the outside of the rotating ring 201b.

[0036] When the rotating ring 201b rotates, it will drive the extrusion strip 201c into the slot 201a-1 and squeeze the inner wall of the slot 201a-1. Through the cooperation of the two, the rotating ring 201b drives the cone support 103 to move to one side of the epoxy sleeve 102, so that the cone support 103 can be locked and fixed. When the rotating ring 201b rotates, multiple extrusion strips 201c will squeeze the inner wall of the slot 201a-1 at the same time. Therefore, the cone support 103 will move synchronously to one side of the epoxy sleeve 102 in one circle, thereby ensuring that the cone support 103 is evenly stressed during installation and avoiding its deviation.

[0037] Specifically, the locking member 201 further includes a positioning block 201d, which is fixed to one side of the rotating ring 201b. A positioning groove 103a is provided on the cone support 103, and the positioning block 201d slides in the positioning groove 103a.

[0038] The positioning block 201d cooperates with the positioning groove 103a to rotatably connect the rotating ring 201b to one side of the cone support 103.

[0039] Specifically, the locking member 201 further includes a stopper 201e, and the stopper 201e is fixed to one side of the rotating ring 201b.

[0040] The moving stroke of the squeezing bar 201c is limited by the stopper 201e to prevent the squeezing bar 201c from moving too far and being separated from the card slot 201a-1.

[0041] Specifically, the positioning block 201d and the positioning groove 103a are both T-shaped.

[0042] Specifically, the pushing member 202 includes a force-bearing block 202a and an extrusion block 202b. The force-bearing block 202a is fixed to the inner side of the rotating ring 201b, and the extrusion block 202b is located on one side of the force-bearing block 202a.

[0043] When the squeezing block 202b moves, it squeezes the inclined surface of the force-bearing block 202a and pushes the force-bearing block 202a to move, so that the force-bearing block 202a can drive the rotating ring 201b to rotate, and the rotating ring 201b can drive the squeezing bar 201c to move.

[0044] Example 3

[0045] Reference Figure 1-Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0046] Specifically, one side of the force-bearing block 202a is inclined.

[0047] Specifically, the pusher 202 further includes a threaded rod 202c, which is rotatably connected to one side of the cone support 103. A threaded hole 202b-1 is provided on the extrusion block 202b, and the threaded rod 202c is internally threadedly connected to the threaded hole 202b-1.

[0048] The threaded rod 202c is rotatably connected to one side of the cone support 103 through a bearing. When the threaded rod 202c rotates, the extrusion block 202b is driven to move through the cooperation of the threaded hole 202b-1, so that the extrusion block 202b can extrude the inclined surface of the force-bearing block 202a. When the cone support 103 needs to be disassembled, it is only necessary to rotate the threaded rod 202c in the opposite direction to separate the extrusion block 202b from the force-bearing block 202a.

[0049] Specifically, a movable groove 202a-1 is formed on the force-bearing block 202a, and the threaded rod 202c is movably connected to the movable groove 202a-1.

[0050] The movable groove 202a-1 can provide the force-bearing block 202a with sufficient space to move, thereby preventing the threaded rod 202c from restricting its movement.

[0051] Specifically, the reset member 203 includes a fixed block 203a and a spring 203b. The fixed block 203a is fixed to one side of the cone support 103, and two ends of the spring 203b are respectively fixed to the fixed block 203a and the force bearing block 202a.

[0052] When the squeezing block 202b is separated from the force block 202a, the spring 203b applies thrust to the force block 202a, and the force block 202a drives the rotating ring 201b to rotate in the opposite direction, so that the rotating ring 201b can drive the squeezing strip 201c to separate from the slot 201a-1.

[0053] When in use, when fixing the cone support 103, the cone support 103 is inserted into the epoxy sleeve 102, and the positioning column 201a is inserted into the cone support 103. At this time, the threaded rod 202c is rotated by a wrench, and the extrusion block 202b is driven to move through the cooperation of the threaded hole 202b-1. When the extrusion block 202b moves, it squeezes the inclined surface of the force-bearing block 202a and pushes the force-bearing block 202a to move, so that the rotating ring 201b can be driven to rotate through the force-bearing block 202a. When the rotating ring 201b rotates, it will bring The movable extrusion strip 201c enters the slot 201a-1 and squeezes the inner wall of the slot 201a-1. Through the cooperation of the two, the rotating ring 201b drives the cone support 103 to move to one side of the epoxy sleeve 102, so that the cone support 103 can be locked and fixed. When the rotating ring 201b rotates, multiple extrusion strips 201c will squeeze the inner wall of the slot 201a-1 at the same time. Therefore, the cone support 103 will move synchronously to one side of the epoxy sleeve 102 in one circle, thereby ensuring that the cone support 103 is evenly stressed during installation to avoid its deviation.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
