In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Embodiment 1: The specific structure of the present utility model is as follows:

[0034] Please refer to the attached Figures 1-6 , A multi-contact high-current terminal quick connector of the present utility model includes a terminal housing, and the terminal housing has a terminal installation cavity, and two channels are separated inside the terminal installation cavity. The terminal housing includes a main housing 4 and a terminal housing 1 fixed to the first end of the main housing 4. A partition is provided inside the main housing 4, and one end of the partition is lower than the orifice at the first end of the main housing 4 to form a step. The main housing 4 is of a rectangular body structure, and an indicator is attached to one of its surfaces, and the indicator is marked with a "+" mark and a "-" mark. The "+" mark is connected to the live wire, and the "-" mark is connected to the neutral wire to avoid incorrect wiring.

[0035] The end shell 1 has a through hole and a raised U-shaped guard plate is provided along the edge of the through hole. The U-shaped guard plate has a protective function and also serves as a guiding function. One end of the main shell 4 where the end shell 1 is installed is provided with a metal nut melted into the main shell 4, and the end shell 1 is connected and fixed to the main shell 4 through screws. The adjacent surfaces of the U-shaped guard plate are perpendicular to each other, and both of its two corners are chamfered.

[0036] The connector further includes a large-current clip assembly 2 and two wiring terminals 3. The two wiring terminals 3 are connected to the first ends of two sets of clip groups one-to-one. The wiring terminal 3 is also commonly known as a copper nose. The second end of the main shell 4 is a cylindrical channel, and the copper nose is fixed by a fastening screw and is located within the cylindrical channel area.

[0037] The large-current clip assembly 2 is installed at one end of the terminal installation cavity. The large-current clip assembly 2 has a bracket 21 seated at one end of the terminal installation cavity and two sets of clip groups 22 symmetrically arranged on the bracket 21. The first ends of the two sets of clip groups 22 respectively extend into two channels, and their second ends extend outwards and both have a clip structure, and the clip structure has a multi-contact structure; the bracket 21 is arranged on the step and covers the orifice at the first end of the main shell 4. The bracket 21 has two first through holes, and the two sets of clip groups 22 are installed in the two first through holes one-to-one.

[0038] The clip group 22 includes a terminal fixing frame 221 and a terminal clip. The terminal fixing frame 221 is an integral structure. Its first end extends into the channel, and its second end extends outwards and fixes the terminal clip. The first end of the terminal fixing frame 221 is a plate-shaped end 2211, and the plate-shaped end 2211 is a plate body structure. A terminal hole 2215 is provided on its plate surface, and one end of the wiring terminal 3 is fixed to the terminal hole 2215 through a fastening screw.

[0039] The outward extending end of the terminal fixing frame 221 is provided with "ㄇ"-shaped frames 2213 arranged in parallel, and there is a gap between the two "ㄇ"-shaped frames 2213;

[0040] Both ends of the two "ㄇ"-shaped frames 2213 facing the channel within the frames are provided with notch openings 2212, and the two notch openings 2212 are arranged back to back. Opposite sides within the frames of the two "ㄇ"-shaped frames 2213 are provided with two pairs of coaxial holes, and rotating shafts 225 are installed in both pairs of coaxial holes. Oval slots 2214 are provided at the outer ends of the coaxial holes to prevent the rotating shafts 225 from being exposed.

[0041] The terminal clamp includes two sets of terminal rows 224 that are oppositely arranged to form a clamping opening, two sets of elastic sheet rows respectively arranged on the back sides of the two sets of terminal rows 224. The two sets of terminal rows 224 are respectively pivotally connected to two rotating shafts 225. The elastic sheet rows are fixed to the terminal fixing bracket 221 through a pressing plate 222. The elastic sheet rows are arranged lower than the terminal rows 224, and the pressing plate 222 is arranged in the notch 2212. As Figure 5 shown, the notch 2212 is provided with a plurality of shaft holes, and the screw 223 passes through the shaft holes and is connected to the nut to fix the two pressing plates 222. As Figure 3 shown, there are six screws 223, and six corresponding nuts are also provided.

[0042] The terminal row 224 is formed by a plurality of conductive fingers closely attached to the side. The outer ends of the conductive fingers are in a pointed structure and have an arch structure. The arches of the two sets of terminal rows 224 face each other to form a clamping opening. The male terminal is inserted into the clamping opening and can contact a plurality of conductive fingers, achieving the purpose of contacting the male terminal at multiple contact points, and further achieving the purpose of passing a large current.

[0043] There are two rows of the elastic sheet rows. The first row of elastic sheet rows 226 abuts against the terminal row 224 and is higher than the second elastic sheet row 225 on the outer layer. The first row of elastic sheet rows 226 and the second elastic sheet row 225 are used to abut and clamp the terminal row 224. When the terminal row 224 is stressed and undergoes an expansion deformation, it will exert a force on the first row of elastic sheet rows 226, and the first row of elastic sheet rows 226 will exert a force on the second elastic sheet row 225. Since the first row of elastic sheet rows 226 and the second elastic sheet row 225 will rebound after being stressed, the first row of elastic sheet rows 226 and the second elastic sheet row 225 will then exert a force on the terminal row 224.

[0044] The bracket 21 is further provided with a second through hole, and at least one needle sleeve 23 is installed at the second through hole.

[0045] As Figure 7 shown, Figure 7 is a structural diagram of the connector of the present invention after being inserted into the first type of male terminal joint 5. As Figure 8 shown, Figure 8 is a structural diagram of the connector of the present invention after being inserted into the second type of male terminal joint 6. The second type of male terminal joint 6 is an L-shaped joint. Figure 9 is a cross-sectional view of the connector of the present invention after being inserted into the second type of male terminal joint.

[0046] In summary, the large-current signal is transmitted to the large-current clip assembly 3 through the male terminal connector, and the large-current clip assembly 3 then transmits the large-current signal through the copper nose and the cable, with stable current transmission. The installation method of the pressure plate 222 makes the assembly more firm. The terminal shell and the bracket 21 are made of insulating materials to ensure the safety of a multi-contact current connector during use. The connector of the present utility model improves the traditional terminal connector, and the clip structure can be used to quickly plug in the connector and conduct current. The connector of the present utility model is provided with a terminal row, which is rotatable and can be pressed tightly by the spring piece row to clamp the incoming male terminal. The terminal row increases the contact points and can conduct large current.
