Description
Technical field
The utility model relates to field of power tools, especially a kind of terminal insulative protective device.
Background technique
Terminals P IN needle is mainly the docking use that electric wire is made on electric tool, and PIN needle is broadly divided into three-hand type and crosspointer
Formula, terminals P IN needle and terminals P IN slot realize the touching of metal and the energization of machine to grafting.
Existing issue is, since terminals P IN needle or terminals P IN slot are exposed components, three needles or crosspointer in terminal
Ferrule is easy to be shorted by metal object and burnt out power supply, and accidentally touching can also cause danger operator when power supply switchs to high pressure.
Utility model content
The purpose of this utility model is to provide a kind of terminal insulative protective device for the existing above problem.
The purpose of this utility model can be realized by the following technical scheme: a kind of terminal insulative protective device, including two
It is a to match the terminal plug docked, terminals P IN needle is set in one of terminal plug, is equipped with terminal in another terminal plug
PIN slot, which is characterized in that the syringe needle of terminals P IN needle is equipped with insulator, and the tail portion of terminals P IN needle is electric conductor, electric conductor
Diameter is matched with terminals P IN slot, and the diameter of the insulator is less than electric conductor diameter, is made in the sub- PIN slot of conductive physical efficiency insertion end.
Terminals P IN needle 2 is connected to the electric current output side of machine, and terminals P IN slot 4 is connected to the electric current to be entered one of machine
Side.
Terminals P IN needle 2 is located at electric current input side, and terminals P IN slot 4 is connected to the electric current side to be output of machine.It prevents
Terminal PIN slot 4 is inserted into 2 short circuit of terminals P IN needle afterwards again.
The electric conductor of the terminals P IN needle is convex, and insulator is rubber or plastic cement material, and insulator covers leading in convex
On electric body.
The electric conductor of the terminals P IN needle is equipped with groove, and the insulator is T-shaped, T-shaped insulator tail portion
It is inserted in the groove of electric conductor fixed.
The T-shaped insulator is PVC material.
The top of the terminals P IN needle is lower than the outer end face of terminal plug.It is further ensured that safety.
Compared with prior art, the utility model is protecting upper safety with higher, not small in front of terminals P IN needle
The heart leans against the danger that conductive short circuit will not be generated on metallic conduction object, can also play the role of false-touch prevention to operator.
Detailed description of the invention
Fig. 1 is the terminal plug schematic diagram of the utility model.
Fig. 2 is the docking schematic diagram of the utility model.
Fig. 3 is the first insulator structure.
Fig. 4 is second of insulator structure.
In figure, 1 terminal plug；2 terminals P IN needles；3 insulators；4 terminals P IN slots；5 electric conductors；6 grooves；7 protrusions.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Shown in Fig. 1-Fig. 2, the utility model includes the terminal plugs 1 of two matching docking, in one of terminal plug 1
If terminals P IN needle 2, terminals P IN slot 4 is equipped in another terminal plug 1.
The syringe needle of terminals P IN needle 2 is equipped with insulator 3, and the tail portion of terminals P IN needle 2 is electric conductor 5, the diameter of electric conductor 5
It is matched with terminals P IN slot 4, the diameter of the insulator 3 is less than 5 diameter of electric conductor, and electric conductor 5 is enable smoothly to be inserted into terminal
In PIN slot 4.Insulator 3 is that 2 front end of terminals P IN needle accidentally touches and causes to be shorted in order to prevent.The top of the terminals P IN needle 2
Portion is lower than the outer end face of terminal plug 1.
The structure of insulator 3 has following two combining form, but is also not necessarily limited to two kinds of forms, first, as shown in figure 3,
5 front end of electric conductor of terminals P IN needle 2 be equipped with groove 6, insulator 3 be it is T-shaped, T-shaped 3 tail portion of insulator is inserted in electric conductor 5
Groove 6 in it is fixed, fixation can use glue, and insulator 3 can use PVC material, and such insulator 3 can hard ability side
Just it is inserted into groove 6.Second, insulator 3 is rubber material as shown in figure 4, the front end of the electric conductor 5 of terminals P IN needle 2 is protrusion 7
Matter, 3 sets of insulator on protrusion 7.
When design, one, terminals P IN needle 2 be connected to the electric current output side of machine, terminals P IN slot 4 is connected to the electricity of machine
Flow side to be entered.So terminals P IN slot 4 is not afraid of short circuit, as long as the control of terminals P IN needle 2 can guarantee safety.
Two, terminals P IN needle 2 is located at electric current input side, and terminals P IN slot 4 is connected to the electric current side to be output of machine.It is anti-
Terminal PIN slot 4 is inserted into sub- 2 short circuit of PIN needle of not-go-end afterwards again.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
