Embodiment

The utility model will be further described below in conjunction with drawings and Examples.

As shown in Figure 1 and Figure 2, the utility model rectangle power connector, comprise plug and socket, wherein plug comprises guide pillar 1 and the plugging hole component 3 that is located on the pin insulator 6, socket comprises guide pin bushing 9 and the contact that is located on the socket insulator 18, described contact is a split-type structural, connect to form by contact head 10 and sheet spring socket 15 sliding inserting, be provided with spring 11 between contact head 10 and the sheet spring socket 15, spring 11 1 ends are connected with contact head 10, and the other end is against on the lining 14 right flanges and with sheet spring socket 15 and insulate.The joint of contact head 10 and socket insulator 18 is provided with radial seal structure, this radial seal structure is in socket insulator 18 cannelure to be set, place contact head O RunddichtringO 12 in the cannelure, thereby contact head 10 interference fit are passed this contact head O RunddichtringO 12 formation radial seal structures.Simultaneously, the end face that plugs together at socket insulator 18 is provided with an annular groove, be placed with a rectangular seal 8 in it, and the middle part of guide pin bushing 9 is provided with guide pin bushing O RunddichtringO 7, the end of guide pin bushing 9 is provided with clamp nut 17, sheet spring socket 15 is provided with socket nut 13 and lining 14, and the rear ends of socket insulator 18 is provided with socket seal pad 16.On the other hand, the plugging hole component 3 of plug is fixed in the pin insulator 6 by plug nut 4, and the middle part of guide pillar 1 is provided with guide pillar O RunddichtringO 2, and the rear ends of pin insulator 6 is provided with plug sealing gasket 5, to realize the sealing of end face.

Plug and socket entered guide pin bushing 9 by guide pillar 1 and align when the utility model plugged together, the end face of the plugging hole component 3 of plug contacts the other end that compression spring 11 makes contact head 10 to front slide and insert 15 li of sheet spring sockets with contact head 10 end faces of socket, thereby make the complete conducting of the corresponding contact with socket of plug to carry out electric power transfer, the locking of connector can realize by the retaining mechanism on battery and the equipment.

Same contact is designed to split-type structural in the socket of the present utility model, promptly same contact is split into two contacts (contact head 10 and sheet spring socket 15), contact and the realization that is used for that separates by spring 11.When plug with after socket separates, the elastic force of spring 11 greater than the separating force of contact head 10 and sheet spring socket 15 to realize separating of contact head 10 and sheet spring socket 15.In order to guarantee the water-tight of contact head 10, be provided with a cannelure in the cooperation place of insulator and contact head and place contact head O RunddichtringO, the contact head interference is passed the sealing circle and is formed radial seal structure, thereby realizes water-proof function.

Socket insulator 18 of the present utility model plugs together end face and also is provided with an annular groove, places a rectangular seal 8 in it, to guarantee the sealing of plug and socket inserting position.

Potted component is adopted in the utility model plug and socket many places, can realize the water-tight of connector; Simultaneously, owing to adopt spring technology and end contact mode, so plug and socket separating force are very little, can realize that battery is connected and separates with the quick of equipment. Specifically comprise following advantage:

A) has water-proof function;

General rectangular connector can not waterproof, and the utility model rectangular power connector not only plug and socket is installed on the casing and can realizes separately waterproof, and plug and socket also can be realized waterproof after plugging together.

B) has the effect of ZIF;

Because the connector contact way of contact is end contact, so contact engaging and separating force is zero, like this with regard to so that plug and socket be connected with separate very convenient, quick.

C) the plug contact has two kinds of ways of contact;

Because the plug contact adds the structure of flat-top sleeve pipe for the sheet spring socket, therefore same plug can with two types the socket interworking that two kinds of pattern contacts are housed, the way of contact of contact is respectively end contact and contacts with sheet spring formula.

D) same contact is non-in the socket plugs together not conducting of state;

The utility model has been realized the non-not conducting of state and the water-tight of dynamic Contact spare of plugging together of same contact in the socket, can avoid battery discharge under water.
