[0026] In order to clearly understand the technical means, creative features, achieved objectives and effects of the present utility model, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0027] Embodiment 1

[0028] As Figures 1-4 shown, a torque locking connection device includes a wire pressing structure and a housing, wherein the housing is arranged outside the wire pressing structure to protect the wire pressing structure.

[0029] The wire pressing structure includes a wire pressing device and a locking device. During the wiring process, the branch wire needs to be connected to the main wire. In this embodiment, one end of the branch wire needs to be connected to the main wire. The wiring position of the main wire is in the middle of the wire body of the main wire, and the wiring position of the branch wire is at one end of the branch wire. The wire pressing structure can connect the main wire and the branch wire and fix them in the wire pressing device through the locking device. One side of the wire pressing structure is arranged in the middle of the wire body of the main wire, and the other end of the wire pressing structure is connected to the branch wire.

[0030] The wire pressing structure includes a wire pressing device and a locking device. The wire pressing device fixes the main wire and the branch wire in the wire pressing device through the locking device. The wire pressing device includes a main body 1 and a wire pressing block 12. A hole for accommodating the branch wire is provided in the main body 1, and the wire pressing block 12 can fix the main wire in the main body 1.

[0031] In this embodiment, referring to Figures 2-4 , the structure of the main body 1 is a branch wire end and a main wire end. The branch wire can extend into the branch wire end for fixation. The main wire end is a hook-shaped structure that can be sleeved outside the main wire. A hole is provided inside the branch wire end, and a fixing port for accommodating the locking device is provided on the side wall of the hole. The main body 1 can fix the main body 1 on the main wire through the main wire end, and the other end of the main body 1 can accommodate the branch wire.

[0032] When the main body 1 is fixed on the main wire, a corrugated fixing structure is provided at the contact surface between the main wire end of the main body 1 and the wire pressing block 12 and the main wire to prevent the main wire from slipping with the wire pressing device and causing an insecure connection.

[0033] Referring to Figures 2-4 , in this embodiment, the locking device includes a torque bolt 2. The torque bolt 2 includes a bolt body and a bolt head. Before fixation, the bolt body is connected to the head. When the torque bolt 2 is arranged on the main body 1, the torque bolt 2 needs to be fixed on the main body 1 with a suitable torque to ensure the fixing effect of the torque bolt 2. When the bolt torque for fixing the main wire or the branch wire is too small, the bolt is likely to fall off. When the bolt torque for fixing the main wire or the branch wire is too large, the bolt will have failures such as cracking or slipping of the thread. In this embodiment, the torque bolt 2 is adopted to ensure that the torque of the torque bolt for fixing the main wire or the branch wire is within a suitable range during fixation.

[0034] During the process of fixing the main body 1 to the branch wire, a torque bolt 2 is required for fixing. One end of the branch wire needs to remove the insulation layer, and the exposed wire is inserted into the interior of the main body 1 and fixed by the torque bolt 2. The bottom of the torque bolt 2 enters the interior of the main body 1 from the side of the hole in the main body 1 that accommodates the branch wire conductor and is fixed in the main body 1 with an appropriate torque. During the process of fixing the main body 1 to the main wire, the main body 1 and the wire pressing block 12 need to cooperate. A hole for accommodating the torque bolt 2 is provided on the side of the main body 1 for fixing the main wire. The torque bolt 2 can pass through the hole in the main body 1 for accommodating the torque bolt 2 and be connected to the wire pressing block 12 to ensure that the position of the wire pressing block 12 moves within an appropriate range. In this embodiment, a screw hole is provided in the middle of the wire pressing block 12, and a stud is provided at the top of the torque bolt connected to the wire pressing block 12. The torque bolt 2 and the wire pressing block 12 are connected and cooperated through the connection between the stud and the screw hole, and the wire pressing block 12 is fixed to the bottom of the torque bolt 2.

[0035] When the main body 1 is installed on the main wire, the torque bolt 2 needs to be connected and fixed to the main body 1 with the wire pressing block 12, and the main body 1 is arranged in the wire body of the main wire. The main body 1 and the wire pressing block 12 are cooperated and fixed on the main wire by rotating the torque bolt 2.

[0036] After the installation of the main body 1 is completed, a housing needs to be provided on the outside of the main body 1 to protect the connection between the main body 1, the branch wire, and the main wire. In this embodiment, a rubber ring is provided at the connection of the housing to ensure waterproof and dustproof after the housing is fixed.

[0037] Refer to Figure 4 , the housing includes an upper housing and a lower housing. The upper housing and the lower housing are connected by a hinge. The gap between the upper housing and the lower housing is the main wire connection point and the branch wire connection point, which facilitates the connection between the upper housing and the lower housing. The top of the upper housing can accommodate the main wire end of the main body 1 and is semicircularly wrapped around the top of the main body 1; the lower housing can accommodate the branch wire end of the main body 1 and includes the bolt body of the torque bolt 2. A groove for accommodating the torque bolt 2 body is provided at the bottom of the lower housing. The upper housing and the lower housing are connected by a lock.

[0038] In this embodiment, the lock uses a fastening device for connection.

[0039] The usage process of the torque locking connection device includes:

[0040] Step 1: Select the main body 1 that can connect to the main wire, that is, the size of the main wire end of the main body 1 is greater than or equal to the thickness of the main wire.

[0041] Step 2: Select the main body 1 that can connect to the branch wire within the main body 1 that can connect to the main wire, that is, the branch wire end of the main body 1 can accommodate the branch wire and the gap meets the requirements.

[0042] Step 3: Set the torque bolt 2 on the hole reserved on the main body 1, but do not fix the torque bolt 2. The bottom of the torque bolt 2 set at the main line end is fixed on the main body 1 through the cooperation of the stud and the screw hole of the wire pressing block 12, and the main line can pass through the gap between the main body 1 and the wire pressing block 12.

[0043] Step 4: Strip the insulating layer at one end where the branch wire needs to be connected, so that the bare wire enters the branch wire end of the main line 1, and tighten the torque bolt 2 set on the side of the branch wire end, so that the bolt head of the torque bolt 2 is separated from the bolt body, and ensure that the torque between the torque bolt 2 and the main body 1 is within a suitable range. Prevent the branch wire from detaching from the main body 1.

[0044] Step 5: First strip the surface insulating layer of the main line, hang the main body 1 on the wire, and then twist the torque bolt 2 at the main line to make the wire pressing block 12 press the wire. The main body 1 is the connection medium between the main line and the branch wire.

[0045] Step 6: Press the wire pressing structure through the outer shell. A rubber ring is provided between the upper outer shell and the lower outer shell for sealing to prevent rainwater, dust, and other sundries from entering the outer shell. The upper outer shell and the lower outer shell are connected and fixed through a buckle.
