Detailed Description

As shown in fig. 1 and 2, in the power line connecting device for the power battery and the testing equipment, a base 10 and an upper cover 20 enclose a ring sleeve area for restraining a power line, a stud 30 is fixed on the base 10/the upper cover 20 in the ring sleeve area, and a nut 40 is connected on the stud 30 in a threaded manner. The effective parcel power line of the restraint region that upper cover 20 and base 10 lock constitute, contact binding post, conductive metal such as double-screw bolt and nut is in the box, the foreign object can't get into in the box easily, play insulating protection's purpose, do not need the winding of reuse insulating tape, the binding post cover of power battery and test equipment's power line tip is on double-screw bolt 30, thereby screw up with nut 40 and realize being connected of power battery and test equipment power line, and compare traditional nut volume, this device nut 40 is bulky, even drop also easily to retrieve.

The concrete structure is as follows: offer the cross-section on the base 10 and be semicircular lower groove 11, the notch of lower groove 11 is arranged up, 11 trough lengths of lower groove are unanimous with the length direction of base 10 and link up the base 10 both ends, offer the cross-section on the upper cover 20 and be semicircular upper groove 21, the notch of upper groove 21 is arranged down, 21 trough lengths of upper groove are unanimous with the length direction of upper cover 20 and link up the upper cover 20 both ends, power battery's power line and test equipment's power line overlap on double-screw bolt 30 from the both sides of lower groove 11 respectively, when base 10 and upper cover 20 lock, lower groove 11 and upper groove 21 butt joint constitute cylindrical cavity, the internal diameter of cylindrical cavity is identical with the external diameter of power line, the effectual external water that prevents, the filth gets into cylindrical cavity indoor, guarantee protector's reliability.

In order to install the stud 30, the platform 12 is arranged in the middle of the lower groove 11, the stud 30 is fixed on the platform 12, meanwhile, the plane of the platform 12 can support a power battery and a wiring terminal at the end of a power line of a testing device, when the base 10 and the upper cover 20 are buckled, the nut 40 sleeved on the stud 30 is located in a cylindrical cavity formed by butting the lower groove 11 and the upper groove 21, the outer diameter of the nut 40 is smaller than the diameter of the cylindrical cavity, and the situation that the base 10 and the upper cover 20 cannot be buckled is prevented.

The side of base 10 and upper cover 20 constitutes normal running fit through the hinge, and the side that opens and shuts of upper cover 20 is provided with buckle 22, and buckle 22 constitutes the joint cooperation with the draw-in groove 13 that the side that opens and shuts of base 10 set up. That is to say that whole device is the box form, because buckle 22 and draw-in groove 13's cooperation, can guarantee the stability of lock, and then improve the reliability of connecting, protecting.

The nut 40 is detachably connected with a hexagonal handle A, so that the nut 40 can be conveniently mounted and dismounted.

The operation of the whole device comprises the following steps: 1. rotating the hexagonal handle A and taking down the nut 40; 2. the power line of the power battery and the test equipment passes through the lower groove 11 and the upper groove 21; 3. a stud 30 on the base 10 penetrates through a power battery and a power line connecting terminal of the testing equipment; 4. the screw bolt 30 is arranged on the nut 40, and the hexagonal handle A is held by hand to be screwed tightly; 5. closing the upper cover 20, and clamping the buckle 22 of the upper cover 20 into the clamping groove of the base 10; 6. when the device is disassembled, the buckle 22 is unlocked; 7. the upper cover 20 is opened, and the hexagonal handle A is held by hand to loosen the nut 40; 8. the power battery and the test equipment power line and the wiring terminal are taken out, and the nut 40 is mounted on the stud 30.
