FIG. 1 is an exploded schematic view of one embodiment of a post assembly of the present application, and FIG. 2 is a partial cross-sectional view of one embodiment of a controller of the present application. According to one embodiment of the present application, the post assembly 100 may include a push-down member 110, a conductive member 120, an attachment member 130, and the like.

The pressing member 110 may be a molded member, for example, integrally molded from an insulating material. In one embodiment, the insulating material may be rubber, plastic, or the like. The pressing member 110 may include a first surface 111 and a second surface 112. The first surface 111 and the second surface 112 may be substantially parallel to each other. In one embodiment, the first surface 111 is oriented away from the circuit board 200 and the second surface 112 is oriented toward the circuit board 200.

The through hole 113 may extend through or through the pressing member 110, e.g., from the first surface 111 to the second surface 112. In one embodiment, the through hole 113 may extend perpendicular to the first surface 111 and the second surface 112. The second surface 112 may further include a recess 114, and the recess 114 may be recessed inward of the pressing member 110 with respect to the second surface 112. In one embodiment, the through hole 113 may be communicated to the recess 114. In one embodiment, the through hole 113 may have a cross section of one of the following shapes: circular, oval, triangular, rectangular, rounded rectangular, prismatic, regular pentagonal, regular hexagonal, or a combination thereof. Recess 114 may have a flat bottom profile, or may have a roof shape or other shape. The shape of recess 114 is adapted to the shape of second extension 122 so that second extension 122 can fit completely within recess 114.

The conductive member 120 may include a first extension 121 and a second extension 122. The first extension 121 and the second extension 122 are in electrical communication with each other. In one embodiment, the conductive member 120 may be bent from a single metal strip, and the two sections after bending form the first extension 121 and the second extension 122, respectively. In one embodiment, the first extension 121 and the second extension 122 are arranged substantially perpendicular to each other. The first extension 121 and the second extension 122 may have the same cross-sectional profile, and the cross-sectional profile may be selected from one of the following: circular, oval, triangular, rectangular, rounded rectangular, prismatic, regular pentagonal, regular hexagonal, or a combination thereof. The conductive member 120 may be made of a metal strip through a bending process, and the conductive member 120 may be one of the following materials: copper, copper alloy, iron, steel, gold, silver alloy, aluminum alloy.

The first extension 121 may extend through the through hole 113 of the pressing piece 110 and protrude from the first surface 111. In one embodiment, the first extension 121 may be positioned substantially perpendicular to the first surface 111. The second extension 122 may be positioned in the recess 114. The contour of recess 114 may be matched to the contour of second extension 122, and second extension 122 may be positioned substantially parallel to second surface 112. In another embodiment, the second surface 112 may not be provided with the recess 114, e.g., the second surface 112 may be flat, and the second extension 122 may be positioned at the second surface 112, or, in other words, adjacent to the second surface 112. In such embodiments, at least a portion of the second extension 122 protrudes from the second surface 112.

The attachment 130 may be used to attach the pressing member 110 and the conductive member 120 to the circuit board 200. In one embodiment, the number of attachments 130 may be one or more. For example, the attachment 130 may be a combination of nuts and bolts, and two sets of nuts and bolts are respectively installed at the ends of the pressing piece 110. For clarity, the nuts are not shown in the drawings, and reference numeral 130 refers only to bolts. Correspondingly, bolt holes 115 may be provided at both ends of the pressing piece 110, respectively, so as to accommodate bolts. In one embodiment, after the bolts are installed into the bolt holes 115, the upper surfaces of the bolts may be positioned substantially flush with the first surface 111. In one embodiment, the upper surface of the bolt may be lower than the first surface 111. To summarize, the upper surface of the bolt may not protrude with respect to the first surface 111. Further, the conductive member 120 may be positioned between two attachment members 130. Thus, the attachment 130 cooperates with the pressing member 110 to position the conductive member 120. In one embodiment, the plurality of attachment members may be disposed about the perimeter of the second extension 122 of the conductive member 120, e.g., substantially uniformly. For another example, the plurality of attachment members may be evenly arranged around the perimeter of recess 114.

When assembled, the first extension 121 of the conductive member 120 extends through the through hole 113 of the pressing member 110, and the second extension 122 of the conductive member 120 is positioned in the recess 114. The attachment 130 connects the press 110 to the circuit board 200 and aligns the second extension 122 with the current contact plate 210 on the circuit board 200. In the illustrated embodiment, the second extension 122 contacts and establishes an electrical connection with the current contact plate 210. The shape profile of the second extension 122 protruding from the second surface 112 of the pressing member 110 helps to establish the electrical connection. Bolts are shown schematically in fig. 2 extending through the press 110 and the circuit board 200. It is readily understood that nuts may be fitted to the bolts from the underside of the circuit board 200 in order to complete the fixing. After assembly is completed in this manner, the conductive member 120 acts as a post and provides an electrical connection to the current contact plate 210 of the circuit board 200.

One or more current contact plates 210 may be disposed on the circuit board 200, and the current contact plates 210 may be spaced apart from each other. The binding post assembly can complete the positioning and the arrangement of the binding posts only by using mechanical parts, so that the manufacturing cost and the processing time are reduced.

Fig. 3 is an exploded perspective view of the embodiment of fig. 1 when assembled, and fig. 4 is a perspective view of the embodiment of fig. 3 when assembled in place. As shown in fig. 3, the current contact plate 210 may be disposed on the circuit board 200, and the post assembly 100 is assembled from above the current contact plate 210. In fig. 4, the post assembly 100 has been installed in place and is covered with a current contact plate 210. On the other hand, fig. 2 can also be regarded as a sectional view of the post 100 and the circuit board 200 in the mounted-in-place state in fig. 4. With assembled in place, the second extension 122 functions as a post, for example, by the circuit contact board 210 serving as a post for the circuit board 200.

Further, in the embodiment shown in fig. 3, the extension portions 116 are provided at both ends of the pressing piece 110, respectively. The extension 116 corresponds to the bolt hole 115, and the extension 116 protrudes with respect to the second surface 112. Extension 116 may be used to receive bolt 130 and may be wrapped around bolt 130. The length of the extension 116 may be arbitrary, for example, the end of the extension 116 may be extended just above the circuit board 200 to contact the circuit board 200, or the end of the extension 116 may be extended into the circuit board 200, or the end of the extension 116 may be extended through the circuit board 200. The extension 116 can position the bolt 130 on the one hand and can enhance the insulating properties of the entire assembly on the other hand. It will be readily appreciated that extension 116 is an alternative construction. Extension 116 and compression member 110 may be an integral piece. In some embodiments, no extension may be provided at both ends of the push member 110.

The present application also relates to a controller comprising the above-described circuit board 200 and one or more terminal assemblies 100. In one embodiment, the controller may be a controller for a vehicle, such as a body controller, a motor controller, or the like. More specifically, the controller may be a motor controller of a two-wheeled electric vehicle.

The wiring terminal assembly and the controller have the advantages of simplicity, reliability, easiness in implementation, convenience in use and the like. The post assembly and controller of the present application also have advantages in terms of manufacturing costs and assembly costs.
