[0023] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, if the terms "set", "installed", "connected", "connected" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0024] The following will Figures 1 to 3 make a detailed description of the present utility model.
[0025] A copper bar non-opening connector includes a body 1. A horizontal copper bar 101 is connected through the insertion opening 103 in a penetrating manner. The bottom of the body 1 is provided with an insertion opening 103. A vertical copper bar 102 is connected to the middle of the insertion opening 103. A wedge block 3 is arranged inside the body 1. A lead screw 2 is connected to the middle of the wedge block 3. A pressing block 4 is connected to one side of the wedge block 3. A connecting component is arranged at the top of the vertical copper bar 102.
[0026] Furthermore, the body 1 further includes a sliding groove 104 and a displacement groove 105. The sliding groove 104 is arranged on one side of the inner wall of the body 1. The displacement grooves 105 are arranged on both sides of the inner wall of the body 1. The wedge block 3 further includes a sliding block 301. The sliding block 301 is a convex block on one side of the wedge block 3 that cooperates with the sliding groove 104. One side of the wedge block 3 is an inclined surface arranged in an inclined manner. One side of the pressing block 4 is an inclined surface that cooperates with the inclined surface of the wedge block 3. The bottom of the body 1 is provided with an opening that cooperates with the wedge block 3. The lead screw 2 is a screw rod with a protruding part at the top of the body 1, and the part of the lead screw 2 that fits into the groove of the wedge block 3 has a matching thread. The pressing block 4 further includes a displacement block 401. The displacement block 401 is a convex block arranged on both sides of the pressing block 4 that cooperates with the displacement groove 105.
[0027] First, the body 1 is connected to the inside of the power distribution cabinet through bolts. Then, the horizontal copper bar 101 is horizontally penetrated into the body 1 for connection. Then, the vertical copper bar 102 is connected through the insertion opening 103 at the bottom of the body 1 and enters the body 1. One side of the vertical copper bar 102 is attached to the side surface of the horizontal copper bar 101. Then, by controlling the rotation of the lead screw 2, the wedge block 3 inside the body 1 is driven to move downward. The movement of the wedge block 3 is stably carried out through the sliding block 301 on one side cooperating with the sliding groove 104. When the wedge block 3 moves, the inclined surface on one side will be attached and abutted against the inclined surface on one side of the pressing block 4. Therefore, when the wedge block 3 moves downward, the inclined surface will exert pressure on the inclined surface on one side of the pressing block 4, forcing the pressing block 4 to displace along the displacement groove 105 through the displacement blocks 401 on both sides until it abuts against the vertical copper bar 102. Then, due to the pressure exerted by the vertical copper bar 102 and the horizontal copper bar 101, the pressure through the abutment will exert an abutting pressure on the vertical copper bar 102 and the horizontal copper bar 101 to stabilize them, so as to stably connect the vertical copper bar 102 and the horizontal copper bar 101.
[0028] Further, the width of the insertion opening 103 should be greater than the thickness of the vertical copper bar 102. The connection component includes a lifting ring 1021 and a hook 5. The lifting ring 1021 is arranged at the top of the inner wall of the body 1, and the hook 5 is arranged at the top of the vertical copper bar 102. The hook 5 is connected to the top of the inner wall of the body 1 through a hinge shaft at one end, and the hinge shaft at one end of the hook 5 is connected through a torsion spring.
[0029] Meanwhile, when connecting the vertical copper bar 102, the lifting ring 1021 at the top of the vertical copper bar 102 will abut against the hook 5. By the abutting pressure, the hook 5 will be forced to deflect through the hinge shaft at one end, so that the lifting ring 1021 will move to one end of the hook 5. Then, the hook 5 is reset by the torsion spring on the hinge shaft, and one end of it will be fitted into the middle of the lifting ring 1021, thus completing the connection. In this way, the vertical copper bar 102 can be stably connected to the inside of the body 1 through the lifting ring 1021. When disassembly is required, lifting the vertical copper bar 102 to a certain extent can separate the lifting ring 1021 from the hook 5. At the same time, the opening widths for connecting the vertical copper bar 102 and the horizontal copper bar 101 are both greater than the vertical copper bar 102 and the horizontal copper bar 101, enabling copper bars of different thicknesses to be fitted in, and then being stably fixed by abutting pressure.
[0030] The following is the specific implementation process of the present utility model. First, the horizontal copper bar 101 is horizontally penetrated into the body 1 for connection. Then, the vertical copper bar 102 is connected through the insertion opening 103 at the bottom of the body 1 and enters the body 1, and one side of the vertical copper bar 102 is attached to the side of the horizontal copper bar 101. Then, the control screw rod 2 is rotated to drive the wedge block 3 inside the body 1 to move downward. The movement of the wedge block 3 is stably carried out by the slider 301 on one side cooperating with the chute 104. When the wedge block 3 moves, the inclined surface on one side will be attached and abutted against the inclined surface on one side of the abutting block 4. Therefore, when the wedge block 3 moves downward, the inclined surface will exert pressure on the inclined surface on one side of the abutting block 4, forcing the abutting block 4 to displace along the displacement groove 105 through the displacement blocks 401 on both sides until it abuts against the vertical copper bar 102. Then, due to the pressure exerted by the vertical copper bar 102 and the horizontal copper bar 101, the pressure through the abutment will exert abutting pressure on the vertical copper bar 102 and the horizontal copper bar 101 to stabilize them, so as to stably connect the vertical copper bar 102 and the horizontal copper bar 101. At the same time, when connecting the vertical copper bar 102, the lifting ring 1021 at the top of the vertical copper bar 102 will abut against the hook 5. The abutting pressure will force the hook 5 to deflect through the hinge shaft at one end, so that the lifting ring 1021 will move to one end of the hook 5. Then, the hook 5 is reset by the torsion spring on the hinge shaft, and one end of it will be fitted into the middle of the lifting ring 1021 to complete the connection, so that the vertical copper bar 102 can be stably connected in the body 1 through the lifting ring 1021. When it needs to be disassembled, lifting the vertical copper bar 102 to a certain extent can separate the lifting ring 1021 from the hook 5. At the same time, the opening widths for connecting the vertical copper bar 102 and the horizontal copper bar 101 are both larger than the vertical copper bar 102 and the horizontal copper bar 101, so that copper bars with different thicknesses can be fitted, and then they are stably fixed through abutting pressure.
[0031] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
