Specific embodiment
In order to make the technical solution of the utility model, purpose and its advantage more clearly, below in conjunction with attached drawing and implementation
Example, is further explained explanation to the utility model.
As shown in Figures 1 to 7, electrical cord assembly is by power supply line 50, terminal 51, terminal clamp 52, brush copper pigtail 53 and riveting
Copper strips 54 forms, and rear end cap is divided into both ends of the surface, and end face is in being equipped with brush box 62 on the brush box installation position 61 of two sides thereon, and
Convex platform 3 is provided between the brush box installation position 61 of two sides, the rear end cap lower end surface corresponds to the convex platform 3 and is provided with
It is provided in lower convex platform 4, the convex platform 3 and lower convex platform 4 up and down and two wiring through-holes 1 arranged side by side, it is described to connect
It is provided with the positioning table 11 of structure annular in shape in line three-way hole 1, the positioning table 11 is coaxially disposed and described with the wiring through-hole 1
112 ring internal diameter of positioning table is less than 1 internal diameter of wiring through-hole.
The positioning table 11 is provided with step groove 12 towards rear end cap lower end surface side, and 12 internal diameter of step groove is big
It is less than 1 internal diameter of wiring through-hole in 111 internal diameter of stepped hole.
Described two wiring through-holes 1, one poroid in having an area of, another is in square hole shape.
The brush box installation position 61 of corresponding two sides, the rear end cap upper surface is symmetrically arranged with two groups of cable clamping interfaces, the card
Wire casing includes the first cable clamping interface 21 and the second cable clamping interface 22, wherein second cable clamping interface 22 is closely set in the convex platform
3, cable clamping interface setting all concordant with the upper surface of the convex platform 3 level.
It is radially extended outside 4 lower end of lower convex platform and is provided with engagement button 41.
Its application principle is as follows:
When electrical cord assembly installation, terminal 51 is inserted into the wiring through-hole first, enables terminal claw 512
It is fastened in the upper limb of the positioning table 11, terminal pawl 511 is fastened in the lower edge of the positioning table 11, to avoid the terminal
51 teetertotter；And fall into the terminal pawl 511 in the step groove 12, make the terminal 51 by step groove 12 limitation and
Avoid double swerve；Complete the fixation of terminal 51.
Then terminal clamp 52 is pushed into the wiring through-hole 1, the terminal clamp 52 is matched with 1 interference of wiring through-hole
It closes, while further fixing electrical cord assembly, water-proof function effectively is formed with to the wiring through-hole 1.
