Description

Direct-contact-prevention connecting structure, connector, battery pack and vehicle

Technical Field

The utility model relates to a connector field specifically relates to a prevent directly touching connection structure and connector.

Background

With the change of national policy, the cost reduction of the electric automobile becomes a necessary trend. The cost of the high-voltage parts accounts for a large proportion of the cost of the electric automobile, and each high-voltage part needs to be correspondingly improved in cost reduction according to development requirements. The cost of the high-voltage connector accounts for a major portion of the cost of the high-voltage cable assembly, and cost reduction of the high-voltage connector becomes an important task for cost reduction in the high-voltage electrical connection system.

The high-voltage electric modules are connected through the high-voltage connector and the high-voltage cable attached to the high-voltage connector in the electric automobile, and the purpose of electric energy transmission and distribution is achieved. Considering the maintenance and the change of electrical module, the connector structure of present trade mainstream is the structure of inserting soon for the most part, and the cooperation that the plug of connector and socket passed through passes through the buckle promptly is fixed to the buckle is provided with the staff and operates the button, does not need under the condition of instrument, can realize the disjunction of the plug of connector and socket fast.

The quick-plug connector must use terminals with pin-hole mating structures, which are expensive to manufacture. With the development of high-power charging, the requirement on the overcurrent capacity of a high-voltage electric connection system of an electric automobile is higher and higher, and the size of a terminal is increased continuously, so that the cost (material cost and processing cost) of the connector terminal matched with the pin hole is increased, and the requirement on cost reduction of the whole automobile is not met.

And the shell of the quick-insertion connector is the assembly of a buckle operated by a human hand and a key, and an additional structure is required to be added. On the heavy current connector, because the terminal size of connector is great, the plug power of inserting when plug and socket cooperation is great, lead to on the connector housing to increase extra helping hand structure, for example utilize helping hand handle of lever principle etc.. These additional structures increase the cost of the connector, and with a large trend to reduce the cost, it is necessary to simplify it.

To solve the above problems, a connector-via connector with a more simplified structure has been proposed in the industry. This connector has abandoned the theory of inserting soon, changes traditional pinhole terminal of mutually supporting into line nose structure, and this kind of terminal is connected through the copper bar in the bolt is direct and the electric module, because the positive pressure of exerting after the bolt is screwed up is far greater than the pinhole terminal of mutually supporting for line nose overcurrent ability performance is more excellent.

Because the wire nose is directly connected with the copper bar, a socket of the quick-insertion connector is cancelled, and only a plug of the connector is reserved. And the wire nose can be processed by stamping through a die, the traditional terminal is generally processed by a machine, and the processing and manufacturing cost of the wire nose is far lower than that of the traditional terminal. The through-hole connector is complex in assembly due to the fact that structures such as buckles, keys and a power-assisted handle are omitted. Bolts are needed to fix a plurality of parts of the connector, and the assembly efficiency of the whole vehicle is reduced. However, the via connector still has a significant cost advantage compared to the quick-plug connector.

The various via connectors currently available on the market have a drawback: the wire noses are connected with the copper bars through bolts, and workers are required to operate through tools. If the worker installs or maintains under the condition that the whole car high voltage connection is not disconnected (such as sintering of the contactor of the battery pack, misoperation of the worker and the like), the risk of electric shock of the worker is caused due to the fact that the tool is in contact with the wire nose and the high-voltage electrified part of the copper bar. Therefore, the through-hole connector is not suitable for a battery pack or the like as an interface of a main loop of a high-voltage system.
