[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0023] Figure 1 A schematic diagram of the overall structure of a terminal block for a low-voltage motor is shown. Figure 1The present invention relates to a low-voltage motor terminal block, comprising a base plate 100 and a cover plate 200 overlapping the base plate 100. Both the base plate 100 and the cover plate 200 are manufactured from BMC material using a mold. The two are combined to form a split-structure terminal block, which facilitates subsequent inspection and maintenance. One of the plates can be replaced individually, reducing maintenance costs. The base plate 100 and the cover plate 200 cooperate to form a through hole for wires to pass through. That is, in the split state, the through hole is in a disassembled state. When the two are installed, they form and restrict the cold-pressed wiring elbow. In actual installation and use, the base plate 100 is first installed at the outlet of the machine casing, and the internal lead wire of the motor is passed through the base plate 100. At this time, the wire is in a relaxed state and is allowed to move. Then, the cover plate 200 is pressed on the top of the base plate 100. The base plate 100 and the cover plate 200 cooperate to form a hole to restrict the wire from passing through. At the same time, the cover plate 200 is fixed to the outlet of the motor with bolts to complete the installation. Then, the cold-pressed wiring elbow is connected to the outside of the wire. Finally, the wiring elbow is hung on the wiring bolts embedded in the cover plate 200 and the nuts are tightened.
[0024] Figure 2 A schematic diagram of the base plate 100 is shown; Figure 3 A schematic diagram of the cover plate 200 is shown; Figure 4 A schematic diagram of the structure after the base plate 100 and the cover plate 200 are assembled is shown; Figure 2In the middle, the base plate 100 includes a base plate 110 and two limiting plates 120. The two limiting plates 120 are spaced apart on the top of the base plate 110 and form a mounting groove 130 for a corresponding cover plate 200 between them. That is, the cover plate 200 can be directly positioned and installed in the mounting groove 130 to achieve splicing with the base plate 100, which is beneficial to the overall molding of the terminal block. The base plate 100 has a through hole 111 and a half-hole 121. The through hole 111 covers half-hole 121 on the horizontal projection surface. Half-Hafu-121; that is, in actual installation, the wire can first pass through the through-hole 111, and then be moved to the half-Hafu-121, thus facilitating the wire insertion; half-Hafu-210 is provided on both the left and right sides of the cover plate 200. In the installed state, the half-Hafu-210 cooperates with the half-Hafu-121 to form a through hole for the wire to pass through; when the cover plate 200 is installed in the mounting groove 130, the half-Hafu-121 and the half-Hafu-121 on the cover plate 200 are connected. The two 210s can cooperate to form a through hole for the matching wire, thereby preventing wire misalignment; at least two sets of wiring modules 220 are provided on the top of the cover plate 200, and there is a raised partition between two adjacent sets of wiring modules 220; it should be noted that the number of wiring modules 220 and the number of through holes are matched, and the positions are also corresponding, that is, the number and position of through holes are set according to the needs of the wiring modules 220; the cover plate 200 has screw holes 230 along the thickness direction; in actual use, a bolt passes through the screw hole 230 and is screwed to the motor, completing the installation of the cover plate 200 while restricting the position of the base plate 100; the edge of the limiting plate 120 extends outward and cooperates with the edge of the base plate 110 to form a stepped structure; in actual use, the motor wiring terminal has a stepped groove that cooperates with the stepped structure, thereby positioning the base plate 100 as a whole and preventing the base plate 100 from shaking after installation; this is beneficial to the stability of the whole installation.
[0025] It should be noted that, in this embodiment, as Figure 3 As shown, there are six sets of semi-half-furnace ports 210, symmetrically distributed on the left and right sides of the cover plate 200. The number and position of semi-half-furnace ports 121 also correspond one-to-one with the semi-half-furnace ports 210. However, in some other embodiments, the specific number and position of semi-half-furnace ports 210 and semi-half-furnace ports 121, as well as whether their distribution is symmetrical, are not limited.
[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
