The mechanical properties of the quick-connect electrical connector 104 are the plugging force of the quick-connect electrical connector 104, i.e., the force required to plug the male plug 41 into the female socket 42 and the force required to plug the male plug out. The magnitude of the force F is determined by the magnitude of the pressure of the contact and the coefficient of friction, where F is μ N, where F is the insertion and extraction force, N is the contact pressure of the contact, and μ is the coefficient of friction. The male plug 41 is worn to some extent during plugging, the wear will cause loose contact and increase contact resistance, which affects the electrical performance of the quick plugging electrical connector 104, so the wear needs to be controlled in a relatively low range to meet the requirement of a certain minimum plugging frequency, that is, the quick plugging electrical connector 104 needs to meet the requirement of service life.
The electrical performance of the quick connect/disconnect electrical connector 104, i.e., the contact resistance R of the quick connect/disconnect electrical connector 104, is lower than the resistance of the quick connect/disconnect electrical connector 104, which actually represents that the quick connect/disconnect electrical connector 104 is more stable in use. The energy storage battery pack105 is usually a large current, the rated current is about 200A, and the heating power of the quick plug electrical connector 104 is I2R, the value of the contact resistance R is important to ensure that the temperature rise of the quick-connect electrical connector 104 is within an allowable range. And contact pressure pairThe influence of the contact resistance is important, and the contact resistance cannot be obviously reduced only by enlarging the contact surface without enough pressure.
The environmental performance is also a very important performance of the quick plugging electric connector 104, the energy storage battery pack105 is usually used in a container, the operating environment is relatively stable, the requirement is not high, the temperature is generally-20 ℃ to +65 ℃, the relative humidity is below 85%, and the container can generally meet the requirement of IP45, so the design of the quick plugging electric connector 104 ensures reliable operation in the above environmental conditions.

The maximum diameter of the multi-point contact spring 43 is consistent with the inner diameter of the plug cylinder 422, and the minimum diameter of the multi-point contact spring 43 is slightly smaller than the maximum diameter of the plug section 411.
The quick-plugging electrical connector 104 is specially used for dealing with the characteristic of high-current connection connected with the energy storage system battery pack105, and in order to prevent the contact resistance of the quick-plugging electrical connector 104 from being too large to cause temperature rise, enough contact pressure is required, but if the contact pressure is too large, the plugging force required during installation is large, the operation is inconvenient, and the service life of the quick-plugging electrical connector 104 can be influenced by the too large contact pressure.
The design of the multipoint contact elastic sheet 43 just solves the problem, because of the existence of the multipoint contact elastic sheet 43, the contact pressure is moderate, when the inserting section 411 is inserted into the inserting cylinder 422, the material of the multipoint contact elastic sheet 43 generates plastic deformation, the surface film of the multipoint contact elastic sheet 43 is crushed, the influence of the surface film on the contact resistance is effectively inhibited, meanwhile, the effective contact area of the multipoint contact elastic sheet 43 is large, the contact resistance can be rapidly reduced, and a stable value can be obtained.
And the design of the multipoint contact elastic sheet 43 can avoid the abrasion caused by the plugging operation as much as possible, and the contact looseness can not be easily caused by reducing the abrasion, so that the contact resistance can not rise randomly, thereby ensuring that the quick plugging electric connector 104 has good electric performance and more plugging times.
Compared with the prior art, the electrical integration function battery rack provided by the application has the advantages that the contact pressure ratio of the quick plugging electrical connector 104 is smaller, the resistance is smaller, even if a larger current passes through the battery pack105 in the combined use process, the battery pack is not easy to generate heat, the electric energy loss ratio is smaller, electric sparks are not easy to generate, serious fire accidents are not easy to cause, and the electrical integration function battery rack is safer.
Need not to splice the electrically conductive cable according to strict regulation, only need simple grafting operation, can realize battery pack 105's quick installation, installation operation is simpler, and packaging efficiency is higher, and because the plug power ratio is moderate, life is also more of a specified duration, and convenient follow-up change battery pack 105.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
