CN201655860U - An electric vehicle battery upper cover with terminals - Google Patents

Abstract

The utility model discloses an electromobile storage battery upper cover with a connecting terminal, comprising an upper cover body on which a terminal installing cavity is formed; the connecting terminal is fixed in the installing cavity; and a lead block penetrating hole is formed under the terminal installing cavity. The connecting terminal is injected and fixed in the installing cavity. The connecting terminal is injected and fixed in the upper cover body, thereby avoiding the condition that epoxy resin as a liquid sealant easily leaks into the inside of a battery to block the reaction of living things due to the epoxy resin as the liquid sealant is adopted for sealing the connecting terminal and the upper cover body or the quality problem that sulfuric acid overflows outwards due to poor sealing of the epoxy resin as the liquid sealant. The utility model also reduces the installing processes as well as the material and labor costs; in addition, the connecting terminal and the upper cover body are easier to install after injected and sealed.

Description

An electric vehicle battery upper cover with terminals

Technical field:

The utility model relates to the field of accumulators, in particular to an upper cover of an electric vehicle accumulator with terminals.

Background technique:

See accompanying drawing 1, the existing electric vehicle battery upper cover includes an upper cover body A, and a terminal connection terminal installation cavity A1 is formed on the upper cover body A; a sealed cavity A2, a lead column piercing hole A3, and one end of the sealed cavity A2 It communicates with the terminal installation cavity A1, and the other end communicates with the lead post installation hole A3. When installing, install the terminal in the terminal installation cavity, and then weld and fix it with the lead post of the battery. The lead post of the battery passes through the lead post The installation cavity A3 and the sealing cavity A2, in order to prevent leakage, are provided with a sealing ring and a sealant for sealing the lead post in the sealing cavity A2. And finally, in order to prevent the connection terminal and the connection terminal installation cavity of the upper cover body A from leaking, a sealant that is sealed with the lead post is also provided to seal the connection terminal and the connection terminal installation cavity. But doing so just increases processing cost and material cost. And the probability of quality problems is high: the liquid sealant epoxy resin is easy to leak into the battery to hinder the reaction of living organisms; or the sealant epoxy resin is not tightly sealed to cause sulfuric acid to overflow.

Utility model content:

The purpose of the utility model is to provide an electric vehicle battery upper cover with connection terminals for the deficiencies of the prior art, and the connection terminals are injection-molded in the upper cover body. In this way, there is no need to use epoxy resin for sealing, and the liquid sealant epoxy resin will not easily leak into the battery to hinder the reaction of living organisms; or the sealant epoxy resin will not be tightly sealed to cause sulfuric acid overflow. question.

The technical solutions of the present utility model are as follows:

An upper cover of an electric vehicle battery with terminals, comprising an upper cover body, a terminal installation cavity is formed on the upper cover body; the connection terminals are fixed in the installation cavity, and a lead column is formed under the terminal installation cavity Pierce the hole.

In the above-mentioned electric vehicle battery cover with terminals, the terminals are injection-molded and fixed in the installation cavity.

In the above-mentioned battery cover of an electric vehicle with terminals, the hole for the lead post passing through is in the shape of an "eight".

In the electric vehicle battery upper cover with terminals, there is a gap between the lead post installation holes of the terminals and the bottom surface of the terminal installation cavity.

In the above-mentioned electric vehicle battery upper cover with terminals, the depth of the terminal installation cavity is greater than the hole depth of the hole through which the lead post penetrates.

In the above-mentioned electric vehicle battery cover with terminals, the depth of the terminal installation cavity is four times the depth of the hole through which the lead post passes.

The beneficial effects of the utility model are:

The utility model fixes the connecting terminal in the upper cover body through injection molding, so as to avoid sealing the two with sealant epoxy resin, and then the liquid sealant epoxy resin will not easily leak into the Things that hinder the reaction of living organisms inside the battery; or quality problems such as the leakage of sulfuric acid caused by the poor sealing of the sealant epoxy resin. It also reduces the installation process, materials, and labor costs, and it is easier to install after the two are injection molded and sealed.

Detailed ways

Embodiment, see Fig. 2 ~ 5, a kind of electric vehicle battery top cover with connection terminal, comprises top cover body 1, and described top cover body 1 is formed with terminal installation cavity 101; Connection terminal 2 is fixed in this installation cavity In 101 , a lead column piercing hole 102 is formed under the terminal installation cavity 101 .

The connecting terminal 2 is injection molded and fixed in the terminal installation cavity 101 .

The lead post piercing hole 102 is in the shape of "eight".

There is a gap between the lead post installation hole 201 of the terminal 2 and the bottom surface of the lead post exit hole 102 .

The depth of the installation cavity 101 is greater than the hole depth of the hole 102 through which the lead post passes.

The depth of the installation cavity 101 is four times the hole depth of the hole 102 through which the lead post passes. Working principle: The upper cover body 1 embeds the terminal 2 into the cover body during injection molding, so that there is no gap that can leak between the upper cover body 1 and the terminal block 2, and there is no need to use sealant for sealing in the future , and installed after injection molding. Transportation is more convenient.
