Embodiment
Specific embodiment is provided below in conjunction with the accompanying drawings, and technical scheme is described in further detail.This implementation
Example is the most preferred embodiment premised on technical solution of the present invention, but protection scope of the present invention is not limited to following embodiments.
As Figure 1-3, a kind of disconnecting switch static contact with homing system, including gland 1, in addition to conduction
Clamping plate 2 and the root of conduction clamping plate 2 and the homing system being slidably matched with conduction clamping plate 2 are arranged on, the homing system includes
Playback part 4, spring 5, the restriction playback part 4 that is used in conduction clamping plate 2 being set in conduction clamping plate 2 move horizontally the limit
The positive stop lug boss 7 of position and the guide sleeve 8 being fixedly installed on outside conduction clamping plate 2, the root extension of the guide sleeve 8 are connected to
In gland 1, stability is consolidated, as shown in Fig. 2 the playback part 4 is provided with the jack 9 inserted for conduction clamping plate 2, jack
9 are extended the track slot 10 for having confession conduction clamping plate 2 to slidably reciprocate to two ends respectively, and the width of the track slot 10 is not small
It is connected with spring 5 between the width of jack 9, the playback part 4 and conduction clamping plate 2, being provided for of playback part limits
The action of conduction clamping plate, it is ensured that spacing and after using the automatic homing of the action when static contact is used, and then avoid
Because deformation and excessive damage that the change of electric current and electromagnetic force is caused；The end of playback part 4 is arranged on inside gland 1
In chute 6；The setting of positive stop lug boss and chute, controls the horizontally and vertically motion of playback part, is more convenient playback part to conduction
The playback control of clamping plate；
The conduction clamping plate 2 is made up of the electromagnetic plate 11 of two pieces of bendings, and conduction clamping plate 2 includes the interior touch panel contacted with moving contact
201st, the bending coupling part 203 of touch panel 201 and outer touch panel 202, bending in the outer touch panel 202 contacted with guide sleeve 8 and connection
The outside of coupling part 203 contacts setting with guide sleeve 8, is set as shown in figure 3, the outside of the bending coupling part 203 is fixed
It is equipped with telescopic platform 12, the inner side of guide sleeve 8 is fixedly installed the boss 3 corresponding with telescopic platform 12, it is to avoid single
The excessive phenomenon for causing electromagnetic plate to deform of electromagnetic repulsion force effect between electromagnetic plate medial and lateral；The root of the conduction clamping plate 2 is consolidated
Surely it is connected in gland 1.
Further, the conduction clamping plate 2 is oppositely arranged by the electromagnetic plate 11 of two block-shaped identical bendings and formed, and is helped
Enter wherein and be clamped in moving contact.
Further, the width of the track slot 10 be more than jack 9 width, facilitate conduction clamping plate insert and because by
Electromagnetic force and slidably reciprocate, moreover it is possible to coordinate spring 5 further limit conduction clamping plate sliding position, it is carried out action it is spacing.
