Card base is slided in draw-in groove from the cambered surface of draw-in groove fixes lid.
This utility model has the advantages that：
A kind of testing terminal lid compatibility test terminal with anti-loosening function is used, it is therefore prevented that short circuit scribing loosens, connects
Line loosens, it is to avoid testing terminal loosens in running and power generation caused to have a strong impact on.Realize testing terminal
All insulate, it is to avoid short circuit, electric shock equivalent risk are brought because terminal is exposed.
The both sides of lid are provided with card base, for lid in the connection of testing terminal.The locking dynamic component of wiring or so is each one
It is symmetricly set on box body, for preventing the loosening of wiring fastening screw on testing terminal.Short circuit scribing limiting component, short circuit are drawn
The locking dynamic component of piece is arranged on the middle part of box body, and short circuit scribing limiting component is used to prevent the level of scribing from sliding, short circuit scribing
Locking dynamic component is used for the loosening for preventing scribing fastening screw.Testing terminal is provided with draw-in groove, and lid is by card base and test end
Draw-in groove on son is connected.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of the testing terminal lid with anti-loosening function.
Fig. 2 is a kind of schematic perspective view of the testing terminal lid with anti-loosening function.
Fig. 3 is the schematic diagram that a kind of testing terminal lid with anti-loosening function is used cooperatively with testing terminal.
In figure：The locking dynamic component 3 of lid 1, testing terminal 2, wiring, short circuit scribing limiting component 4, short circuit scribing are anti-loosening
Part 5, card base 6, draw-in groove 7.
Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As Figure 1-3, a kind of testing terminal lid with anti-loosening function, it includes lid 1,1 upper end of the lid
Face is plane, and the lower surface two ends of the lid 1 are provided with card base 6, and the card base 6 is constituted with the draw-in groove 7 at the top of testing terminal 2
Hook-shaped snap-fit, the bottom of the lid 1 are provided with the locking dynamic component 3 of wiring, and the bottom of the lid 1 is near middle part
Short circuit scribing limiting component 4 is provided with, the side of the short circuit scribing limiting component 4 is provided with the locking dynamic component 5 of short circuit scribing,
The lid 1 is engaged installation with testing terminal 2.
Further, the locking dynamic component 3 of the wiring is made using the resilient insulant of tool, and its bottom is smooth, in
Between internally be in certain curvature, and be hollow structure.When lid 1 is arranged on testing terminal 2, the locking dynamic component of wiring 3
Tightly being withstood on by its own resilient prevents the loosening of wiring in wiring fastening screw.
Further, the short circuit scribing limiting component 4 is made using the resilient insulant of tool, and bottom is smooth, adopts
Use hollow structure.When lid 1 is arranged on testing terminal 2, short circuit scribing limiting component 4 is stuck in short circuit scribing paddle-tumble and prevents
The level of short circuit scribing is slided.The limiting component of short circuit scribing when mounted 4 can occur certain deformation, it is to avoid scribing is not complete
