Description

Waterproof guillotine connector

The invention relates to a connector structure, and in particular to a waterproof guillotine connector.

Electric vehicles are a form of transportation that use electric energy to drive the wheels to rotate, which is energy-saving and environmentally friendly. Batteries are used to provide electric energy for electric vehicles. Among them, guillotine-type batteries are widely used because of their ease of use and stable power supply.

During the use of electric vehicles, it is possible to wade through water or experience rain and snow, so the battery needs to be designed to be waterproof to prevent the battery from malfunctioning or reducing its service life due to water intrusion. A common practice is to set a sealing ring between the battery connector body and the battery mechanism, and use the sealing ring to achieve waterproofing.

However, the existing sealing rings have a simple structure and require at least two sealing rings to seal in the radial and axial directions respectively. The waterproof effect is poor, the installation process is complicated, and the installation efficiency is low.

In view of this, the author has devoted himself to research on the above-mentioned existing technology and cooperated with the application of academic theory to try his best to solve the above-mentioned problems, which has become the goal of the author's improvement.

This invention provides a waterproof guillotine connector, which uses a water-proof sealing body to set and tighten a plurality of guillotine heads through a plurality of second perforations, and the convex ring will deform and abut against the inner peripheral wall of the slot, so as to achieve a waterproof guillotine connector The connector has excellent waterproof effect.

In an embodiment of the invention, the invention provides a waterproof guillotine connector for use in a slot. The waterproof guillotine connector includes: a body having a bump, and the bump is provided with a plurality of first through holes; A plurality of terminals are connected to the plurality of first through holes and have a plurality of guillotine heads exposed on the bump; and a water-stop sealing body has a convex portion covering the outside of the bump, and the convex portion is provided with the A plurality of second perforations arranged opposite to the plurality of first perforations extend with a convex ring. The water-stop sealing body is sleeved through the plurality of second perforations and tightens the plurality of guillotine heads; wherein, the convex block, the convex part and the When a plurality of guillotine bits are inserted into the slot, the convex ring will deform and abut against the inner peripheral wall of the slot.

Based on the above, the water-stop sealing body has a convex portion that completely covers the bump. The water-stop sealing body is sleeved through a plurality of second perforations and tightens a plurality of guillotine heads, thereby effectively preventing water vapor from passing through the gap where the guillotine head and the base body meet. Penetrates into the base body and when the waterproof guillotine connector is inserted into the slot of the female connector, the convex ring will deform and press against the inner peripheral wall of the slot to form a ring of structure that blocks the entry of water vapor to achieve the waterproof type of this invention The guillotine connector has excellent waterproof effect.
