Further, the conduit 350 includes a lower tube 351 having a semicircular shape with an upward opening and fixed to the rear portion of the lower cover 110, and an upper tube 352 having a semicircular shape with a downward opening and fixed to the rear portion of the upper cover 120; the upper pipe 352 and the lower pipe 351 have the same diameter; the outer walls of the upper pipe 352 and the lower pipe 351 are both provided with external threads, and semicircular cushion pads are fixed on the inner walls of the upper pipe 352 and the lower pipe 351. Further, a semicircular upper tube 352 is provided at the rear portion of the upper cover 120, and a semicircular lower tube 351 provided at the rear portion of the lower cover 110 is closed to form a wire conduit 350 for passing a wire.

Further, to optimize the above design, a semicircular anti-slip buffer pad (not shown) is fixed on the inner walls of the upper tube 352 and the lower tube 351, and the material of the buffer pad (not shown) may be elastic rubber or elastic resin, which is not limited herein. Through the effect of blotter (not shown in the figure), increase wire rod and conduit 350's frictional force, effectively avoided the wire rod to lead to the fragile problem of the outer insulating layer of tie point when frequently using simultaneously, not only promoted the power consumption security greatly, and through the cladding effect of blotter (not shown in the figure), strengthened the fixed action to the wire rod, make the wire rod can be more stable be fixed in on this device.

Further, a reinforcing cap 360 with an internal thread matching with the external thread of the conduit 350 is also included; the tail of the reinforcing cap 360 with the internal thread is provided with a through hole for the lead to pass through. When the upper cover 120 is overlapped with the lower cover 110, the upper pipe 352 and the lower pipe 351 can be fixed by screwing the reinforcing cap 360, thereby achieving the purpose of fixing the upper cover 120 and the lower cover 110. Meanwhile, under the cooperation of the spring pieces 340, the wires entering through the wire guide 350 and the reinforcing cap 360 are compressed, so that the clamping and fixing of the wires are realized. Avoided the fixed of using the screw mode, made the cost cheaper, the installation of being more convenient for need not to use outside instrument can realize the fixed of wire rod and the fixed of upper and lower lid, uses labour saving and time saving more, has promoted the installation effectiveness greatly.

Further, the connection terminal 200 includes a socket 210 for inserting a wire connector, a spiral spring 220 disposed at the bottom of the connection terminal 200, a clip 230 disposed at the top of the spiral spring 220, a cover 260 disposed at the top of the connection terminal 200, a top plate 240 fixed at the bottom of the cover 260 and corresponding to the clip 230 and having an arc shape, a pressing rod 250 hinged to an edge of the cover 260, and a pressing tooth 270 fixed to the pressing rod 250 and penetrating through the cover 260 for controlling the clip 230 to move up and down.

Further, the top sheet 240 is preferably made of copper sheet to ensure good conductivity. The length of the pressure lever 250 can be changed correspondingly according to actual requirements, and according to the lever principle, the longer the pressure lever 250 is, the more labor-saving the pressure is. Through holes are formed in the two sides of the middle of the cover 260 to allow the pressing teeth 270 to pass through the cover 260 and press downward to form a channel. The cover 260 may be fixed to the connection terminal 200 of the lower portion by means of a snap-fit, so as to form a complete connection terminal 200. The width of the top plate 240 should be smaller than the width between the two pressing teeth 270 disposed on both sides of the pressing rod 250 to avoid interference when pressing down. Through the arc top plate 240, the contact area of the wire rod joint and the top plate 240 is increased, so that the conductivity is greatly improved, and the safety of power utilization is ensured. In practical use, the pressing rod 250 is pressed, the lower pressing teeth 270 press the clamping piece 230 to move downwards under the driving of the pressing rod 250, so that a socket 210 for connecting a wire is formed in the clamping piece 230 and the top plate 240, a wire joint is inserted into the socket 210, then the pressing rod 250 is loosened, and under the elastic force of the spiral spring 220, the clamping piece 230 moves upwards, so that the wire is clamped between the top plate 240 and the clamping piece 230, and the connection of the wire is realized.
