DETAILED DESCRIPTION

[0032] To make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0033] As shown in the figure, Figure 1 the present application proposes a profiled resistor 10, which comprises a profiled shell 100, a resistor lead structure 200 arranged in the profiled shell 100, and a resistor module 300 detachably arranged in the profiled shell 100, and the resistor module 300 is detachably connected with the resistor lead structure 200. In this way, the resistor module 300 can be detached and installed according to needs, so that different performance resistor modules 300 can be replaced without changing the appearance of the profiled shell 100 of the profiled resistor 10.

[0034] Specifically, as shown in the figure, Figures 1 to 5 the profiled shell 100 can comprise a main shell 110 provided with a mounting port 112, and a closure shell 120 detachably arranged at the mounting port 112. Moreover, the main shell 110 is formed with a mounting cavity 114, and the mounting port 112 is in communication with the mounting cavity 114. By arranging the profiled shell 100 of the profiled resistor 10 as an openable structure, i.e. by detachably arranging the closure shell 120 at the mounting port 112 of the main shell 110 of the profiled shell 100, the closure shell 120 can be detached to open the mounting port 112 of the main shell 110, so that the resistor module 300 arranged in the mounting cavity 114 can be detached and replaced.

[0035] Moreover, according to the profiled requirements, the profiled resistor 10 can be a battery profiled resistor 10 or other types of profiled resistor 10. As shown in the figure, Figure 1As shown, when the profiled resistor 10 is set as a battery profiled resistor 10, the main shell 110 of the profiled shell 100 can be set as a cylinder body extending in the axial direction with a mounting cavity 114, and the mounting port 112 can be formed on the side wall of the cylinder body, and the closure shell 120 can be detachably mounted at the mounting port 112. By detaching and mounting the closure shell 120, the opening and closing of the mounting port 112 can be realized. In this way, the resistance module 300 can be installed in the mounting cavity 114 of the profiled shell 100 through the mounting port 112, and generally the resistance module 300 can be arranged in the mounting cavity 114 of the cylinder body in the axial direction; it is also convenient to detach the resistance module 300 arranged in the mounting cavity 114 of the profiled shell 100 through the mounting port 112, and convenient to replace the resistance module 300.

[0036] Further, the shape of the closure shell 120 matches the shape of the main shell 110, so that the shape of the closure shell 120 can be consistent with the shape of the main shell 110, without affecting the overall shape of the profiled shell 100. Specifically, when the main shell 110 of the profiled shell 100 is set as a cylinder body, the mounting port 112 can be an arc-shaped window formed on the side of the cylinder body. Correspondingly, the closure shell 120 can be set as an arc-shaped shell and can be detachably arranged at the arc-shaped window of the main shell 110 by a buckle connection.
