Abstract
The invention discloses a contact connection structure of a voltage resistant tooling. The structure comprises a static end conductor and a moving end assembly. The static end conductor is fixedly mounted on the voltage resistant tooling. The moving end assembly comprises a conductive rod, a moving end contact, a contact base and a compression spring. The moving end contact is mounted on the contact base. The contact base is movably mounted at the upper end of the conductive rod. A limiting mechanism for limiting fall-off of the contact base is arranged at the upper end of the conductive rod. The lower end of the conductive rod is rotationally mounted on the voltage resistant tooling. The compression spring is mounted between the moving end contact and the upper end of the conductive rod. One end of the compression spring resists against the moving end contact. The other end of the compression spring resists against the limiting mechanism at the upper end of the conductive rod. The compression spring provides pressure for contact of the moving end contact and the static end conductor. The structure is simple in structure, convenient in assembly, low in production cost and even in electric field and satisfies voltage resistant and partial discharging demands relatively well.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
Consulting shown in Fig. 1 to Fig. 4, the pressure frock contact head attachment structure of one that the present invention discloses, including quiet end conductor 1 and moved end assembly 2, quiet end conductor 1 is fixedly mounted in pressure frock 3.
As it is shown in figure 1, moved end assembly 2 includes moved end contact 21, contact base 22, conducting rod 23 and compression spring 24.Moved end contact 21 is arranged on contact base 22.In the present embodiment, moved end contact 21 is socketed on contact base 22 and fixes by screw 25, forms containing cavity 26 between moved end contact 21 and contact base 22.
Contact base 22 is movably arranged on conducting rod 23 upper end, and the position-limit mechanism that restriction contact base 22 comes off is set in conducting rod 23 upper end, in the present embodiment, described position limiting structure is joint 27, joint 27 includes connecting portion 271 and limiting section 272, and limiting section 272 is arranged on connecting portion 271, and the width of limiting section 272 is more than the width of connecting portion 271, connecting portion 271 is connected with conducting rod 23 upper end, and contact base 22 is actively socketed on outside connecting portion 271.Certainly, position-limit mechanism can also be other structure, and meanwhile, position-limit mechanism can be one-body molded in conducting rod 23 upper end.
Connecting portion 271 forms connecting hole 273, and connecting hole 273 medial wall forms female thread, and conducting rod 23 upper end forms external screw thread, threaded in the connecting hole 273 of conducting rod 23 upper end insertion connecting portion 271.
