DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 to Figure 2 As shown, the double-column rotary isolating switch outlet seat includes an outlet seat body 100. The interior of the outlet seat body 100 is a cavity structure, forming an outlet seat inner cavity 101. The first connector 110 and the second connector 120 are respectively formed at both ends of the outlet seat body 100. The outer side walls of the first connector 110 and the second connector 120 are both arc-shaped. A first through hole 111 is opened at the center of the first connector 110, and a second through hole 121 is opened at the center of the second connector 120. The first through hole 111 is connected to the second through hole 121 through the outlet seat inner cavity 101.

[0015] In actual application, the conductive shaft passes through the first through hole 111, passes through the outlet seat inner cavity 101, and then passes through the second through hole 121, so as to ensure that the conductive shaft can rotate in the outlet seat inner cavity 101. In order to ensure that the conductive shaft does not directly contact the first through hole 111 and the second through hole 121, a plurality of annular grooves 122 arranged at equal distances are coaxially opened on the tube wall of the outlet seat inner cavity 101 inwardly of the second through hole 121, and the annular grooves 122 are used to install insulating sleeves.

[0016] The top of the outlet seat body 100 is formed with an outlet portion 130 on the side close to the first connector 110. The outlet portion 130 is provided with an outlet opening 131 on the outer wall facing the second connector 120. The outlet opening 131 is used for outlet wiring and heat dissipation of the structure in the outlet seat inner cavity 101. The top of the outlet portion 130 protrudes upward to form a boss 132. A positioning hole 133 is provided at the center of the boss 132. A plurality of connecting holes 134 are provided on the boss 132 around the positioning hole 133. Both the positioning hole 133 and the connecting hole 134 are through holes. Both the positioning hole 133 and the connecting hole 134 are used to install and connect other electrical components connected to the outlet seat. The positioning hole 133 is located at the center of the boss 132 and extends upward to facilitate the fixed positioning of other electrical components when they are installed.

[0017] A mounting base 140 is formed downwardly at the bottom of the outlet seat body 100, and a mounting hole 141 is formed at the center of the mounting base 140. The mounting hole 141 is a blind hole. The mounting hole 141 is used to fix the outlet seat as a whole on the high-voltage disconnector.

[0018] In the present invention, the first connector 110, the second connector 120, the outlet portion 130 and the mounting base 140 are all integrated with the outlet seat body 100. Compared with the traditional outlet seat, the structure is simplified, which not only reduces the production difficulty and production cost, but also reduces the overall weight of the outlet seat, enhances the heat dissipation effect, and is conducive to improving the stability of the high-voltage disconnector during operation.

[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0020] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
