On side, it is provided with the side of the protective cover and withholds groove, be provided with the circular hole and stick up bar, described being stuck up pass through in the middle part of bar
Rotary shaft is connected in circular hole, is provided with the medial extremity for sticking up bar and is compressed post, is provided with inclination button in the outboard end for sticking up bar
Hook, is provided with back-moving spring between the diapire for sticking up bar and the circular hole, the bottom of plug-in strip when the plug-in strip is closed with static contact
Face is pressed on and compresses on post, makes to stick up bar and to rotate centered on rotary shaft withholding in groove so that inclining clasp and moving up to withhold
Protective cover is fixed.
Anti-skidding burr is provided with the top surface for compressing post.
Guiding bar groove is provided with the circular hole, is provided with the surface for compressing post and is engaged with the guiding bar groove
Guide runner.
The post that compresses is for insulating ceramics post.
This utility model has positive effect：Simple structure of the present utility model, simple operation work as plug-in strip when using
When mutually closing with static contact, the inclination clasp for sticking up bar outboard end can withhold withholding in groove in protective cover, be not easy protective cover
Be removed, not only can ensure safety in utilization, while plug-in strip is also possible to prevent when electric fuse is changed being on static contact
State, cannot ensure the technical deficiency that moving contact is disconnected with static contact, so as to significantly when solving conventional art installation insurance silk
Safety in utilization is improve, the suitability is good and practical.
Description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to this utility model, wherein：
