[0024] As a technical optimization solution of the present utility model, by providing a fixing mechanism 8, when two electric wires are inserted into the positioning device 5 and the fixing grooves 3 are evenly divided at the wire ends, after the positioning posts 4 are screwed to fixedly connect the two electric wires, during the process of reinserting the movable block 7 into the observation groove 6, as the movable block 7 is gradually inserted into the installation groove 801, the inclined surface of the clamping block 802 contacts the corner of the observation groove 6. Then, with the continuous pushing of the movable block 7, the clamping block 802 is squeezed and guided by the inclined surface to contract into the installation groove 801, squeezing the spring 803 to deform and generate a resilience force. Then, when the clamping block 802 is pushed to coincide with the connection groove 804 of the installation groove 801, the resilience force of the spring 803 will be instantly released, pushing the clamping block 802 to insert into the connection groove 804, so that the clamping block 802 is simultaneously located in the installation groove 801 and the connection groove 804.

One end of the traction rope 902 is fixedly connected to the bottom of the clamping block 802, and the other end of the traction rope 902 is fixedly connected to a spherical handle 903.

[0026] As a technical optimization solution of the present utility model, by providing the unlocking mechanism 9, when it is necessary to extract the clamping block 802 from the connection groove 804 so that the movable block 7 can be extracted from the observation groove 6, the user pulls the traction rope 902 along the trajectory of the L-shaped groove 901 outward through the spherical handle 903, so that the movable block 7 is pulled, squeezing the spring 803, and then gradually contracting into the installation groove 801 until it is completely extracted from the connection groove 804.

During the process of the movable block 7 being pulled out from the observation groove 6, the limiting blocks 11 at the bottom on both sides of the limiting block 11 move along the trajectory of the limiting groove 10 following the movable block 7, thereby restricting the moving distance of the clamping block 802 and preventing the resilience generated when the spring 803 is squeezed when the user releases the pull on the traction rope 902 after the movable block 7 is completely pulled out from the observation groove 6 from pushing the clamping block 802 up to disengage from the installation groove 801 and affecting subsequent use, thus improving the stability of the moving distance of the clamping block 802 pushed by the resilience of the spring 803.

[0029] Reference Figure 2 , positioning grooves 12 are provided on the rear sides of the top and bottom of the inner wall of the installation groove 801, and the inner walls of the positioning grooves 12 are communicated with the inner wall of the fixing groove 3.

[0030] As a technical optimization solution of the present utility model, by providing the positioning groove 12, when the movable block 7 is pulled out from the observation groove 6, opening a gap in the fixing groove 3, and then evenly dividing the wire ends of the two wires in the fixing groove 3, the central demarcation line of the fixing groove 3 is provided through the positioning groove 12, so that the user can pull the wire to quickly divide the fixing groove 3 evenly, thereby improving the working efficiency of the user.

[0031] Reference Figure 1 and Figure 2 , a rubber pad 13 is fixedly connected to the front side of the surface of the movable block 7, and the surface of the rubber pad 13 is movably connected to the front side of the inner wall of the observation groove 6.

[0032] As a technical optimization solution of the present utility model, by providing the rubber pad 13, when the movable block 7 is inserted into the observation groove 6, the rubber pad 13 will be squeezed by the movable block 7 and the observation groove 6 and deform, thereby increasing the contact area between the movable block 7 and the observation groove 6, reducing the gap between the movable block 7 and the observation groove 6, improving the sealing degree, and preventing rainwater from penetrating through the gap to the connection part of the two wires and causing short circuits and other situations when the connecting sleeve 1 is connected to the outdoor wires in rainy days.

[0033] Reference Figure 1 and Figure 2 , a hanging rope 14 is fixedly connected to the left side of the bottom of the front surface of the movable block 7, and the other end of the hanging rope 14 is fixedly connected to the left side of the bottom of the front surface of the connecting sleeve 1.

[0034] As a technical optimization scheme of the utility model, a hanging rope 14 is provided to connect the movable block 7 to the connecting sleeve 1 without interfering with the travel required for the movable block 7 to be pulled out of the observation slot 6, so that after the movable block 7 is pulled out of the observation slot 6, it is hung aside by the hanging rope 14, so that after the ends of the two electric wires are evenly divided into the fixed slot 3, the movable block 7 can be quickly found and inserted into the observation slot 6, thereby preventing the movable block 7 from being lost due to improper storage and causing losses.

[0035] The working principle and use process of the utility model are as follows: when it is necessary to use the connecting sleeve 1 to connect two wires, the user pulls the traction rope 902 through the ball handle 903 to pull it out along the L-shaped groove 901 trajectory, so that the movable block 7 is pulled, the spring 803 is squeezed, and then gradually shrinks into the installation groove 801 until it is completely pulled out of the connecting groove 804, and then as the traction rope 902 continues to be pulled, the movable block 7 is gradually pulled out from the observation groove 6, and the fixing groove 3 is opened. Then, the positioning device 5 is screwed into the connecting groove 2 through the thread, and then the port on the outside of the positioning device 5 is pulled to open it. At this time, the end of the wire with the rubber peeled off can be inserted and moved close to the fixing groove 3. At the same time, the center dividing line provided for the fixing groove 3 by the positioning groove 12 provides a stop insertion point for the wire ends of the two wires. At this point, the wire ends of the two wires are quickly aligned to divide the fixing groove 3 equally, and then the connecting sleeve can be twisted. 1, so that the positioning column 4 simultaneously and evenly squeezes the wire ends of the two wires, so that the two wires are fixedly connected, and now the movable block 7 can be inserted into the observation slot 6 again. During the insertion process, the inclined surface of the card block 802 first contacts the corner of the observation slot 6, and then with the continuous pushing of the movable block 7, the card block 802 is squeezed and, guided by the inclined surface, shrinks into the installation slot 801, squeezing the spring 803, causing it to deform and generate a rebound force, and then when the card block 802 is pushed to the installation slot 801 and the connecting slot 804 coincide, the rebound force of the spring 803 will be released instantly, pushing the card block 802 to insert into the limited connecting slot 804, so that the card block 802 is simultaneously located in the installation slot 801 and the connecting slot 804, and then using the card block 802 that is simultaneously located in the installation slot 801 and the connecting slot 804, the movable block 7 is finally limited and fixed, and the fixed slot 3 is closed, thereby having the advantage of auxiliary alignment.

[0036] In summary, for the positioning device of the wire connector, by providing the observation slot 6, when the user connects two wires through the connecting sleeve 1, the movable block 7 is pulled to extract the movable block 7 from the observation slot, so that the fixing slot 3 opens a gap. Then, when the wire heads of the two wires are inserted into the fixing slot 3, it can be observed and adjusted to evenly divide the fixing slot 3 by the wire heads of the two wires. This solves the problem that when the wire heads of the two wires are inserted into the fixing slot and aligned, the observation angle of the fixing slot is not good, and it is not easy to evenly divide the fixing slot by the wire heads of the two wires, resulting in the positioning post squeezing the wire heads. When fixing the connection of the two wires, the pressure received by the two wire heads is uneven, causing the wire head with less contact with the fixing slot to break, affecting the use.
