[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3A terminal installation structure that is easy to install includes a shell 1 and a terminal 2. A limiting groove 3 is provided on the inner side of the shell 1 for limiting the terminal 2 from the front and left and right sides. The terminal 2 is installed on the bottom surface of the limiting groove 3.

[0024] In the utility model, the inner side surface of the housing 1 has two L-shaped baffles 4 connected in one piece, the two L-shaped baffles 4 are arranged opposite to each other, and a limiting groove 3 is formed on the inner side of the two L-shaped baffles 4 .

[0025] In the present invention, the two L-shaped baffles 4 have integrally connected positioning strips 8 on the opposite inner sides.

[0026] In the present invention, the bottom sides of both ends of the terminal 2 are respectively provided with positioning grooves 9 corresponding to the positioning strips 8 .

[0027] Therefore, when the terminal 2 is placed in the limiting groove 3 , the positioning strips 8 on both sides are respectively inserted into the positioning grooves 9 on both sides, thereby playing a role in positioning the terminal 2 .

[0028] In the present invention, two L-shaped retaining bars 5 are provided with an opening 5 between opposite ends, so as to facilitate manual operation, that is, manual placement and removal of the terminal 2 .

[0029] In the utility model, the bottom surface of the limiting groove 3 is provided with three screw holes 6 , forming three installation points, so as to ensure the reliability of the installation of the terminal 2 .

[0030] Furthermore, the three screw holes 6 are arranged at intervals along the length direction of the limiting slot 3 .

[0031] In the utility model, the terminal 2 is provided with countersunk holes 7 penetrating the upper and lower end surfaces thereof, respectively, and screws (there are also three corresponding ones, not shown in the figure) are respectively passed through the countersunk holes 7 (usually there are several, greater than three), and are screwed into the corresponding screw holes 6, so as to realize the fixed installation of the terminal 2 on the bottom surface of the limiting groove 3, and facilitate disassembly.

[0032] At this time, the positioning strips 8 on both sides are respectively inserted into the positioning grooves 9 on both sides to play a role in positioning the terminals 2 .

[0033] In the utility model, the shell is an ABS plastic shell, and the terminal 2 is a nylon glass fiber terminal, which has the characteristics of low cost and light weight.

[0034] In addition, the nylon fiberglass terminal has good strength and can adapt to high torque installation conditions when installing the wiring copper busbar.

[0035] The utility model is further described below in conjunction with the accompanying drawings:

[0036] During installation, first place the terminal 2 in the limiting groove 3, so that the two L-shaped retaining strips 5 limit the terminal 2 from the front and the left and right sides respectively, and the positioning strips 8 on both sides are respectively inserted into the positioning grooves 9 on both sides to position the terminal 2. In this way, the terminal 2 can be stably positioned on the inner side of the shell 1.

[0037] At the same time, the three countersunk holes (whose upper end is a hexagonal hole and the lower end is a round hole with internal threads) 8 on the terminal 2 are made to correspond to the three screw holes 6 one by one.

[0038] Then, screw the three screws into the lower ends of the three screw holes 6 and the three countersunk holes 7 (i.e., the round holes with internal threads at the lower ends) from bottom to top (i.e., from outside to inside), and the terminal 2 can be fixedly installed on the bottom surface of the limiting groove 3, that is, the terminal can be fixedly installed on the inner side surface of the shell 1.

[0039] When installing the copper busbar, first put the nut into the upper end of each countersunk hole 7 (i.e., the hexagonal hole at the upper end), put the copper busbar on, and then screw in and tighten the fixing screw.

[0040] Since the terminal 2 adopts a nylon glass fiber terminal, its strength is reliable. Therefore, when the wiring copper busbar is installed, that is, when a large torque is required to tighten the fixing screws, the nylon glass fiber terminal can withstand the installation condition of the large torque, and the upper end of each countersunk hole 7 (that is, the hexagonal hole at the upper end) will not be damaged, so that the nut therein will not be rotated, and then the fixing screws can be tightened, thereby ensuring that the wiring copper busbar can be installed in place.

[0041] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0042] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
