Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1-7, the drop-resistant protection head for the european standard socket terminal designed by the present invention includes a large diameter section 10 and a small diameter section 20 fitted in a convex groove 31 of a terminal 30. The large-diameter section 10 and the small-diameter section 20 are coaxially arranged and are of an integrally formed structure, so that the processing difficulty and cost are reduced, and the overall strength of the protective head is obviously improved. The small diameter section 20 is a hollow cylindrical structural member, and the outer diameter thereof is smaller than the diameter of the large diameter section 10, thereby increasing the assembly toughness of the protection head.
The side wall of the small-diameter section 20 is provided with two arc-shaped bosses 21 and two elongated openings 22, and the arc-shaped bosses 21 and the elongated openings 22 are arranged at intervals along the circumferential direction of the small-diameter section 20. The arc-shaped boss 21 serves to fix the position, and it cooperates with the convex-shaped groove 31 of the terminal 30 to fit the small-diameter section 20 into the terminal 30. The long-strip-shaped opening 22 is arranged to increase the assembly toughness of the protection head, so that the protection head is convenient to mount and simultaneously achieves the purpose of falling resistance. Rectangular shape opening 22 is seted up along path section 20 length direction, and its both ends are the arc structure to ensure when the assembly toughness of protection head is showing the increase, its bulk strength also obviously promotes, thereby improves its resistant performance that falls, effectively avoids under the unexpected condition people to touch the terminal, and then protects new forms of energy electric automobile's the safety of charging.
In a preferred embodiment of the above technical solution, as shown in fig. 1, 2, 3 and 6, a chamfer guide structure 211 is provided on a side of the arc-shaped boss 21 away from the large-diameter section 10. Further improve through setting up chamfer guide structure 211 the installation convenience of protection head, chamfer guide structure 211 plays the guide effect in the assembling process.
