[0028] The terminal sealing cover comprises a top cover 1 and a side wall 2 extending from the top cover 1 to one end; the side wall 2 comprises a receiving portion 21 for receiving the terminal and the terminal, and a fixing portion 22 for being sleeved on the outer periphery of the terminal fixing seat and being fixed with the outer periphery of the terminal fixing seat by interference fit; the receiving portion 21 is provided with a fixing structure 23 for inserting and fixing the terminal 3; the fixing structure 23 is provided with a through hole 231 for the terminal to penetrate and for contacting and connecting the penetrated terminal and the terminal 3.

[0029] By interfering the fixing part 22 with the terminal fixing seat, the installation of the terminal sealing cover and the terminal fixing seat is greatly facilitated, and the sealing of the terminal sealing cover and the terminal fixing seat is also achieved, and there is no need to use auxiliary components such as screws and bolts, which saves materials, saves costs, and improves production efficiency. Further, by inserting the terminal 3 into the fixing structure 23, when the fixing part 22 is interferingly fixed with the terminal fixing seat, the terminal passes through the through hole 231 of the fixing structure and contacts and connects with the terminal 3 in the fixing structure 23, which facilitates the quick connection of the terminal 3 and the terminal, and further improves production efficiency.

[0030] In one embodiment, in order to further seal the terminal block and the terminal block 3, a sealing partition 232 is provided between the accommodating portion 21 and the fixing portion 22, and a solid structure is provided between the sealing partition 232 and the top cover 1; the fixing structure 23 is provided in the solid structure, and a through hole 233 for the terminal block to pass through and communicate with the through hole 231 is provided on the sealing partition 232. After the terminal block passes through the through hole 233, it enters the accommodating portion 21, and then passes through the through hole 231 before contacting and connecting with the terminal block 3 in the fixing structure 23.

[0031] Please also see Figures 8 to 9 , Figure 8 Schematic diagram of the structure of the wiring terminal in the embodiment of the present invention; Fig. 9 for Figure 8 Side view of the terminal block shown.

[0032] In one embodiment, in order to conveniently connect the terminal 3 to the terminal post, the terminal 3 includes two connecting pieces 31, an elastic buckle 32 and a lead wire fixing seat 33; the two connecting pieces 31 are arc-shaped; the two connecting pieces 31 are arranged opposite to each other, and one end of the two connecting pieces 31 is connected to each other and fixed to the lead wire fixing seat 33, and the other end of the two connecting pieces 32 is fixed to each other, and the side walls of the two connecting pieces 31 form an accommodating space 34 for the through-going terminal post and the terminal post to be in contact and connected. The fixed end of the elastic buckle 32 is fixed to one end of the connecting piece 32, and the movable end of the elastic buckle 32 is arranged between the two connecting pieces 31. After the terminal post passes through the through hole 231, it is arranged in the accommodating space 34 and contacts the side wall of the accommodating space 34, that is, contacts the side walls of the two connecting pieces 31, thereby realizing the rapid connection between the terminal 3 and the terminal post. At the same time, the terminal 3 is clamped in the fixing structure by the elastic buckle 34, thereby realizing the stable fixation of the terminal 3 and the terminal post.

[0033] In one embodiment, the fixing structure 23 includes a plurality of receiving grooves 234 corresponding to the positions of the terminal posts; and each of the receiving grooves is provided with the through hole 231 .

[0034] In a more preferred embodiment, in order to prevent the connection posts and connection terminals in each receiving groove from being separated from each other and to avoid problems such as short circuits, each receiving groove is adjacent and isolated from each other by a partition bar 235 .

[0035] In one embodiment, in order to achieve a stable contact connection between the terminal post and the terminal 3, a positioning boss 236 for clamping in the accommodation space of the terminal is provided at the bottom of each of the accommodating grooves 234; the through hole 231 is provided on the positioning boss 236. A positioning groove 237 for clamping the elastic buckle 32 of the terminal is provided at the top of each of the accommodating grooves, so that the terminal 3 has a certain clamping force in the accommodating groove 234 and is fixed, so as to avoid loosening of the terminal 3 due to movement, etc., and prevent the terminal 3 from escaping from the accommodating groove 234.

[0036] In one embodiment, one side of the accommodating portion 21 extends in a direction perpendicular to the fixing portion 22 and protrudes from the fixing portion 22. The extended accommodating portion 21 allows the connecting post to have enough space to accommodate the connecting terminal 3 after the connecting post is in contact with the connecting post, thereby preventing the connecting terminal 3 from becoming loose or even disconnected from the connecting post after the top cover 1 moves; at the same time, a certain space is left between the outside world and the connecting terminal 3 and the connecting post to prevent water and dust from entering.

[0037] In a more preferred embodiment, in order to further enhance the sealing effect, a sealing ring may be added to the inner wall of the fixing portion 22 to reduce the gap between the fixing portion 22 and the terminal fixing seat.

[0038] Please also see Figure 10 to Figure 11 , Fig.10 In another embodiment Figure 3 A cross-sectional view along the AA direction is shown; Fig.11 for Fig. 9 The side view structural diagram is shown.

[0039] In another embodiment, since the terminal sealing cover is formed by integral injection molding, in order to prevent the problem of deformation of the top cover 1 due to thermal expansion and contraction when the top cover 1 is manufactured after the fixed structure 23 is set in the solid structure, the two sides of the fixed structure 23 are respectively fixedly connected to the accommodating portion 21, that is, the non-connected part of the fixed structure 23 and the accommodating portion 21 is a hollow structure, thereby preventing deformation due to thermal expansion and contraction.

[0043] When in use, each terminal 3 is inserted into each receiving groove 234 of the fixing structure along the positioning boss, so that the elastic buckle 32 of each terminal is clamped in each positioning groove 237, thereby fixing each terminal 3. Next, the terminal post sealing cover is sleeved on the terminal post fixing seat, and the terminal post sealing cover is pressed down, so that the fixing part 22 and the terminal post fixing seat are interference-fixed, and at the same time, each terminal will pass through the through hole 231 on each receiving groove 234, and then enter the receiving space 34 of each terminal, so that each terminal is in contact with the inner wall of each terminal, thereby realizing both the installation of the terminal post sealing cover and the terminal post fixing seat and the connection of the terminal post and the terminal.

[0044] By interfering the fixing part with the terminal fixing seat, the installation of the terminal sealing cover and the terminal fixing seat is facilitated, and the sealing of the terminal sealing cover and the terminal fixing seat is also achieved, and there is no need to use auxiliary components such as screws and bolts, which saves materials, saves costs, and improves production efficiency.
