Description

A kind of high-tension connector

Technical field

This utility model relates to new-energy automobile parts technical field, a kind of high-tension connector.

Background technology

New-energy automobile is the Green Product that country greatly develops, and no matter is hybrid vehicle, pure electric automobile Or fuel cell car, being required for can be resistant to elevated temperatures in the environment of the high voltage more than 300V and the big electric current of hundreds of ampere Cable and adapter.High-tension connector is made up of plug and socket, and the electric current passed through due to high-tension connector is relatively strong, and change is relatively Greatly, it is being easily formed bigger magnetic field about, for avoiding impact to control element manipulation, so the plugs and sockets of high-tension connector must add Screen layer is used for shielding electromagnetic interference, it is ensured that vehicle driving safety.Adapter is generally by the mode of installation shield at present, Its mode is to install shield in the middle of plastic casing, because it is mounting structure, need to leave space between the ectonexine of plastics, The space causing needs is relatively big, then needs certain bindiny mechanism because being connected with each other inside and outside plastic casing, causes shield necessary Leaving and dodge space grooved, it is incomplete to there is screen layer cladding in this mode, there is leakage field problem, it is impossible to meet high-tension connector The requirement of 360 ° of shieldings；And wrap up screen layer and add workload to installment work, reduce the work efficiency installed.

Summary of the invention

The purpose of this utility model is for above-mentioned deficiency of the prior art, it is provided that a kind of high-tension connector.

The purpose of this utility model is achieved through the following technical solutions:

A kind of high-tension connector, including plug and socket, described plug and socket is respectively used to connect cable and electrical appliance Casing, plugs the electrical connection realizing electrical appliance with outside electrical equipment by plug and socket, and described plug has and is embedded with gold Belong to the plastic casing of shield, described in be embedded with the plastic casing of metal shield and include internal layer shell, metal screen from the inside to the outside Cover layer and outer casing, described in be embedded with the plastic casing of metal shield for by described internal layer shell, metal screen layer and outer Layer housing uses the integrated plastic casing that injection molding becomes.

In the further design of this utility model, the above-mentioned plastic casing being embedded with metal shield is being inserted with described The described internal layer shell of seated connection spigot is shorter than described metal screen layer, and described metal screen layer is shorter than described outer casing.

In the further design of this utility model, above-mentioned high-tension connector is single high-tension connector or twin-core high pressure Adapter or three core high-tension connectors.

This utility model has a beneficial effect highlighted below:

1, use injection setting-in shield without considering to install fluting, 360 degree of shielding requirements of adapter can be met.

2, the metal screen layer in plastic casing can increase the intensity of housing.

3, enhancing the security performance of high-tension connector, the ectonexine of plastic casing is plastic overmold, interior meets isolation Electrical equipment gap between shielding and forceful electric power conductor metal and creep age distance, can avoid outward human body directly to contact with metal parts.

4, the volume of adapter can be reduced, it is not necessary to consider to be commonly installed the problem that mode needs bigger space interval.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail:

Embodiment 1

Seeing accompanying drawing 1 and accompanying drawing 2, a kind of two core high-tension connectors, including plug and socket, plug and socket is respectively used to Connecting cable and electrical appliance casing, plugged the electrical connection realizing between two purpose electric appliance by plug and socket, plug has embedding Plastic casing 1 equipped with metal shield；The plastic casing 1 being embedded with metal shield includes internal layer shell 2, gold from the inside to the outside Belong to screen layer 3 and outer casing 4, be shorter than metal screen layer 3, metal screen layer 3 at the internal layer shell 2 patching end with described socket It is shorter than outer casing 4.

Embodiment 2

Seeing accompanying drawing 3 and accompanying drawing 4, a kind of three core high-tension connectors, including plug and socket, plug and socket is respectively used to Connecting cable and electrical appliance casing, plugged the electrical connection realizing between two purpose electric appliance by plug and socket, plug has embedding Equipped with the plastic casing 1 of metal shield, the plastic casing 1 being embedded with metal shield includes internal layer shell 2, gold from the inside to the outside Belong to screen layer 3 and outer casing 4.The plastic casing 1 being embedded with metal shield of plug is patching in end with described socket Layer housing 2 is shorter than metal screen layer 3, and metal screen layer 3 is shorter than outer casing 4.The plastics being embedded with metal shield of socket Housing 1 is shorter than metal screen layer 3 at the internal layer shell 2 patching end with plug, and metal screen layer 3 is shorter than outer casing 4.
