Abstract
The utility model discloses a high voltage connector of an electric automobile. The high voltage connector includes a mounting support, a high voltage cable, a shielding layer, an insulator and a sealing ring. The high voltage cable is fixed in the mounting support. The shielding layer is arranged in the mounting support. The insulator is fixed on the mounting support on a face facing towards a connecting direction. A high voltage terminal of the high voltage cable protrudes from the mounting support and exposes out of the surface of the insulator. The high voltage connector of the electric automobile is also provided with an interlocking connector. The interlocking connector is a low voltage connector installed on the insulator. After a short circuit signal is input, the short circuit signal is output from a low voltage interface of the interlocking connector. After the interlocking connector is connected correctly to the high voltage connector, two low voltage cables in the interlocking connector are switched on. A system controller can judge whether the high voltage connector is connected correctly or not according to the switching state of the detection cables. The high voltage connector of the electric automobile in the utility model has a shielding function and has advantages of high generality, good waterproof capability, small volume and low cost.
Description
Technical field
The utility model belongs to electrical connector, in particular to a kind of electric automobile high-voltage connector structure.
Background technology
In the new-energy automobile field, high-voltage connector one end connects high-tension cable, and an end connects the high voltage component on the car, is one of of paramount importance part of high-voltage line beam system.At present, the high-voltage connector that uses on the new-energy automobile is of a great variety, and architectural difference is bigger, in general, two most important shortcomings is arranged, and the firstth, single line connects, and unshielded function can not be changed polytype cable, and versatility is not high; The secondth, volume is bigger, and function of shielding is arranged, and can change the cable of different size, but cost is high.
Summary of the invention
The technological order of the utility model provides a kind of electric vehicle high-voltage connector, makes connector have function of shielding, high, little, the lower-cost advantage of volume of versatility.
The following technical scheme of the concrete employing of the utility model:
A kind of electric automobile high-voltage connector; It comprises mounting bracket, high-tension cable, screen, insulator and sealing ring; Said high-tension cable is fixed in the mounting bracket, and screen is set in the mounting bracket, and mounting bracket is simultaneously gone up the fixed insulation body towards patching direction; The HV Terminal of high-tension cable stretches out from mounting bracket, and is exposed to insulator surface; It is characterized in that: also be provided with the interlocking connector, said interlocking connector is a low pressure connector, is contained on the insulator, after short-circuit signal is introduced, draws from the low-voltage interface of interlocking connector.This interlocking connector high-voltage connector connect correct after, two low pressure wire harness conducting in the interlocking connector, whether correctly system controller can judge high-voltage connector connection through the break-make that detects wire harness.
Said interlocking connector set inside short circuit lead or copper guide card, short circuit lead or copper are led the outer injection molding body structure that is, injection molding body snaps in insulator, and injection molding body and insulator assembly are bayonet arrangement.
On insulator, also be provided with positioning boss, positioning boss is arranged, groove structure that matees with the location convex of the registration interface designs of the high voltage component that cooperates with high-voltage connector, thus guarantee the uniqueness of high-voltage connector at assembly direction.
The assembling position injection moulding of said high-tension cable and mounting bracket is formed with injection molding body, through injection molding body bayonet socket and mounting bracket matching and fixing.Change the injection molding body mould like this, can change the cable specification, can realize that the cable in the certain limit exchanges.
Said mounting bracket is made up of two blocks of aluminium sheets up and down, and screen is clipped between two blocks of aluminium sheets, fixes through the press-connection machine crimping, and gauze screen is reliably contacted with support.
Described HV Terminal is a copper conductor, electroplating surfaces with tin, and diameter 8mm can carry the 150A continuous current, passes to carry automobile high-voltage electricity stream.
Said sealing ring is used for the connector sealing, is ellipsoidal structure, and design three road reinforcements are arranged in sealing ring in the reinforcement groove on the circumference at insulator fitting tight circle place, are used to guarantee the sealing of connector installed surface.
This connector has function of shielding, high, little, the lower-cost advantage of volume of versatility.
