Description

A kind of socket

Technical field

The utility model relates to a kind of socket, is specially adapted to field uses such as used for electric vehicle electrokinetic cell bag.

Background technology

At present, the high-power battery bag is applied to the electric automobile field at large.In these purposes, battery pack is the high current charge-discharge with hundreds of amperes through regular meeting, in order to improve utilization rate of electrical, reduces heat release, wishes to reduce as far as possible the contact resistance between battery pack internal resistance and battery pack and the power consumption equipment.And, for the ease of maintenance, wish that above-mentioned junction is convenient to dismounting.

In the known technology, modal is by double-screw bolt, nut the extreme and power cable of battery pack to be coupled together.This connected mode has the following disadvantages: in the motor vehicle assembling process, generally be earlier power brick to be fixed on the car body, again power cable is installed in power brick extreme on owing to must use manually or electric wrench when screwing nut, in narrow space, operating difficulties; Sometimes, connection is hot line job under high-tension electricity, must guarantee staff's personal safety, prevents to occur between power brick, the vehicle short circuit damage battery and vehicle, and this has further increased the difficulty of operation again.In the vehicle maintenance process, there are the problems referred to above equally.

At other parts of electric automobile,,, there is similar problem with being connected of power cable as motor control box etc.

Summary of the invention

The utility model proposes a kind of socket, this socket can be fixed on the battery pack case easily, and can be used with commercially available quick cable plug (as Amphenol Radsok C380G09), thereby realize power brick extremely with power cable between the instrument of exempting from be connected fast.

The socket that the utility model provides is by jack housing, external insulation supporter, contact pin, interior insulation support body, fixedly snap ring is formed.Jack housing by inside and outside housing and fixedly square plate constitute.Jack housing can or process with metal or their alloy castings such as steel, aluminium, copper.Jack housing also can adopt the commercially available connector shell that adheres to specification (as WEIPU WS32K4Z), to reduce cost.External insulation supporter and interior insulation support body constitute by the different two parts cylinder of diameter, and respectively there is a through hole centre, its size respectively with contact pin on the contact pin body and the external diameter of double-screw bolt match.

External insulation supporter and interior insulation support body can be made with insulation such as resin, heat proof material.Contact pin is to be made of contact pin body, fixed station, double-screw bolt three parts.Contact pin can be made with materials such as copper, nickel, steel, preferably makes with copper material.And its appearance can be silver-plated, nickel, tin etc. is in case oxidation, reduction contact resistance are preferably silver-plated.

Fixedly snap ring is that a cross section is the jump ring of rectangle.The standard component that can preferred dimension adheres to specification.

During assembling, contact pin body with contact pin inserts in the through hole of external insulation supporter earlier, double-screw bolt with contact pin inserts in the through hole of interior insulation support body again, after the alignment, add auxiliary spacer, screw with screwing nut again, reinstall in the jack housing, fixing snap ring near card in of faucal place inboard or two grooves.

The socket that the utility model provides not only can use at batteries of electric automobile and wrap, but also can be used for other electric automobile parts such as electric machine controller, can also be used for other suitable occasions.

Embodiment

Be illustrated below in conjunction with accompanying drawing with to the utility model.And following example is the example that the utility model is specialized, and does not constitute the qualification to technical scope of the present utility model.

As Fig. 2, shown in Figure 3, the socket 1 that the utility model provides is by jack housing 2, external insulation supporter 3, contact pin 4, interior insulation support body 5, fixedly snap ring 6 and auxiliary pad 7, nut 8 are formed.

Jack housing 2 by inside and outside housing and fixedly square plate constitute.The shell body outside is threaded 20; The inner housing inner shafts has one or two groove 22 radially to an anti-rotation boss 21 is arranged near inboard, faucal place; In the middle of the inside and outside housing fixedly square plate 23 is arranged respectively, uniform 4 installing holes on the square plate, square plate is less than the inner housing internal diameter in the aperture of enclosure interior.

External insulation supporter 3, interior insulation support body 5 constitute by the different two parts cylinder of diameter, and respectively there are a through

hole

31 and 51 in the centre, its size respectively with contact pin 4 on contact pin body 41 and the external diameter of double-screw bolt 43 match.Thicker part divides 32 and 52 diameter to match with jack housing 2 inner housing internal diameters, and respectively has

groove

33 and 53 vertically, and

groove

33 and 53 matches with the inner anti-rotation boss 21 of jack housing 2 inner housings; Insulation support body 3, interior insulation support body 5 thicker parts divide and all have an

oblong slots

34 and 54 on the end face vis-a-vis outside.

External insulation supporter 3, interior insulation support body 5 can be made with insulation such as resin, heat proof material.

Contact pin 4 is made of contact pin body 41, fixed station 42, double-screw bolt 43 3 parts.

The diameter of contact pin body 41 should match with the aperture of the contact 10 of commercially available plug 9 shown in Figure 5, and the top outer rim has annular groove 40 one, and the snap close on the

cap

11,12 of groove and commercially available plug 9 matches.

Fixed station 42 and external insulation supporter 3, interior insulation support body 5 thicker parts divide on the end face

oblong slots

33 and 53 vis-a-vis to match.

Fixedly snap ring 6 is that a cross section is the jump ring of rectangle.The standard component that can preferred dimension adheres to specification.

During assembling, the contact pin body 41 with contact pin 4 inserts in the through hole 31 of external insulation supporter 3 earlier, and the double-screw bolt 43 with contact pin 4 inserts in the through hole 51 of interior insulation support body 5 again, and after the alignment, shimming 7 screws nut 8.Reinstall in the jack housing 2, in groove 22, block fixedly snap ring 6.

After the assembling,, can prevent relatively rotating between the three by cooperating of jack housing 2 inner anti-rotation boss 21 and external insulation supporter 3, interior insulation support body 5 outside grooves 33 and 53.Cooperate with the fixed station 42 of contact pin 4 by the

oblong slots

34 and 54 on external insulation supporter 3, interior insulation support body 5 end faces respectively, can prevent the rotation of contact pin 4.By fixing stopping of snap ring 6, can prevent contact pin 4 and external insulation supporter 3, interior insulation support body 5 and jack housing 2 relative displacement in the axial direction.

During use, only socket 1 need be contained on the installing hole of holding successfully in advance on the power brick metal cabinet, pass fixing hole on the square plate 23 and the installing hole on the power brick casing, screw nut and fix and get final product with 4 screws.The box house line is installed on the double-screw bolt of contact pin 4.

After power brick has been assembled, the head protector that female resin is made can be installed on the screw thread 20 of jack housing, with at power brick accumulating time protection contact pin with prevent to get an electric shock.
