Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As it is shown in figure 1, a kind of lug wire installation for killer switch contact, this lug wire installation comprises: a pair contact contact 10, the cross section of contact contact 10 is semicircular arc；A pair contact connecting rod 20, the top of a pair contact connecting rod 20 contacts the middle part of contact 10 respectively and connects with a pair；Rotating shaft 30, rotating shaft 30 is arranged on this position to the middle part infall of contact connecting rod 20；A pair taper knob 40, a pair taper knob 40 be nested with respectively this to contact connecting rod 20 bottom；Spring 50, spring 50 be arranged on this to contact connecting rod 20 between；Test connection structure 60, above-mentioned test connection structure 60 is arranged on contact connecting rod 20 bottom, for killer switch contact, lug wire installation being connected with testing equipment, carries out the dependence test to killer switch contact.
As in figure 2 it is shown, each contact connecting rod 20 is provided with: a pair spring fixed clip 21, it is symmetrically arranged in the contact connecting rod 20 between contact contact 10 and rotating shaft 30；Spring conductor rod 22, is arranged in this contact connecting rod 20 between a pair spring fixed clip 21.
As shown in Figure 1 and Figure 2, the two ends of spring 50 are nested with respectively on a pair spring conductor rod 21, and are positioned between a pair contact connecting rod 20 by multiple spring fixed clips 21.The setting of spring 50 is able to ensure that this lug wire installation can use " fit and unclamp " principle.When a pair contact connecting rod 20 of this device is in open configuration at initial condition, when pressing handle overlaps the contact connecting rod 20 of 40 positions, close contact can be closed in the two ends of a pair contact contact 10.
Test connection structure 60 is arranged in taper knob 40, and is connected with contact connecting rod 20 bottom.A pair taper knob 40 is insulation material sheath, and during to avoid utilizing test connection structure 60 to disconnect test connection, mode operating personnel is wounded by residual charge.The external diameter of contact contact 10 is less than the inlet diameter of outside killer switch contact.
