Description

Technical Field

[0001] This utility model relates to the field of terminal-related technology, and in particular to a wire-type high-current through-wall terminal. Background Technology

[0002] Currently, most similar 4-core high-current through-wall terminals on the market consist of four conductive busbars. For example, the instruction manual includes... Figure 1 The wall-penetrating terminal shown has four conductive busbars (D) installed in its mounting slot. The three busbars on the left are used to connect to the three-phase live wires, and the one on the right is used to connect to the neutral wire or ground. The ends of the two left busbars are bent downwards and extend below the terminal block, while the rear ends of the two right busbars are bent to the left for a certain length and then extend downwards below the terminal block. The rightmost busbar, connected to the neutral wire or ground, has its rear end bent to the left for a certain length and then extending downwards below the terminal block, resulting in excessively high production costs for the wall-penetrating terminal. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a wire-through high-current through-wall terminal to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a through-wire high-current wall terminal is designed, comprising: a terminal base, four threaded posts disposed on the terminal base, a first conductive bus, a second conductive bus, a third conductive bus, a fourth conductive bus that respectively mate with the four threaded posts, and four wire clamping nuts. The ends of the first conductive bus and the second conductive bus are bent downward and extend to the bottom of the terminal base. The rear end of the third conductive bus is bent to the left and extends downward to the bottom of the terminal base. The rear end of the fourth conductive bus is electrically connected to a conductive cable, which is bent to the left and extends downward to the bottom of the terminal base.

[0006] By adopting the above technical solution, a conductive cable is electrically connected to the rear end of the fourth conductive busbar. The conductive cable bends to the left and extends downward to the bottom of the terminal block. The conductive cable replaces the original left-bending and downward-extending part of the rear end of the conductive busbar. Relatively speaking, this can save manufacturing costs, reduce the production cost of the through-wall terminal, and does not affect the original performance.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the fourth conductive busbar has a front bend and a rear bend. The snap-fit ​​hole on the rear bend engages with a snap-fit ​​block on the terminal block. A locking screw is provided on the front side of the fourth conductive busbar, and the threaded end of the locking screw passes through a through hole in the front bend and engages with a threaded hole in the terminal block. This provides a better fixation effect for the fourth conductive busbar.

[0009] In some embodiments, the conductor of the conductive cable is connected to a clamping part disposed on the rear side of the rear bend.

[0010] In some embodiments, a cover plate is provided above the conductive cable to shield it, and the cover plate is snapped onto the terminal block or locked in place by screws. Thus, the conductive cable can be concealed by the cover plate, achieving the visual effect that the fourth conductive busbar is also made of all-copper busbar.

[0011] In some embodiments, three wire clamping bolts are provided below the terminal block. The three wire clamping bolts respectively pass through the through holes at the lower ends of the first conductive busbar, the second conductive busbar, and the third conductive busbar, and are threadedly engaged with the nuts provided on the terminal block.

[0012] In some embodiments, a mounting plate is provided on the front side of the cover plate, and the left and right ends of the mounting plate are vertically slidably engaged with the guide grooves on the terminal block.

[0013] In some embodiments, the top of the terminal block is provided with a first mounting groove, a second mounting groove, a third mounting groove and a fourth mounting groove, and the threaded post, the first conductive busbar, the second conductive busbar, the third conductive busbar and the fourth conductive busbar are respectively disposed in the first mounting groove, the second mounting groove, the third mounting groove and the fourth mounting groove.

[0014] In some embodiments, a sealing ring is provided at the bottom of the terminal block. Attached Figure Description
