The electrical connector has a first connector, a second connector, and a retainer. The first connector has a first connecting portion and a first protruding end portion that are integrally connected with each other. The second connector has a second connecting portion and a second protruding end portion that are integrally connected with each other. The second connector and the first connector are independently formed elements, respectively. The retainer is integrally interconnected with the first connector and the second connector. The second connecting portion is electrically connected with the first connecting portion. The first protruding end portion is arranged to protrude from the retainer to electrically connect a first mating connector. The second protruding end portion is arranged to protrude from the retainer to electrically connect a second mating connector. The electrical connector of the present disclosure as a modularized assembly may be applied to a plurality of scenarios and thus has extremely high universal flexibility. ## Claims ### Claim 1 An electrical connection assembly for electrically connecting any one of a plurality of battery cells in a battery pack to a circuit board, the electrical assembly comprising: one or more electrical connector modules, each electrical connector module comprising: a first connector comprising a first connecting portion and a first protruding end portion that are integrally connected with each other; a second connector comprising a second connecting portion and a second protruding end portion that are integrally connected with each other, the second connecting portion being electrically connected to the first connecting portion; and a retainer integrally interconnected with the first connector and the second connector; wherein the second connector and the first connector are independently and separately formed elements; wherein the first protruding end portion is arranged to protrude from the retainer to electrically connect to a first mating connector; and wherein the second protruding end portion is arranged to protrude from the retainer to electrically connect to a second mating connector; a support frame having a plurality of mounting grooves, each of the mounting grooves is configured to removably retain one of the one or more electrical connector modules; wherein the one or more electrical connector modules are removably retained in the plurality of mounting grooves. ### Claim 2 (depends on 1) The electrical connection assembly according to claim 1, wherein: the first mating connector and the second mating connector are provided on the support frame; the first mating connector is electrically connected to the first protruding end portion of the first connector for electrically connecting to a battery cell; and the second mating connector is electrically connected to the second protruding end portion of the second connector. ### Claim 3 (depends on 1) The electrical connection assembly as recited in claim 1, further comprising a circuit board, wherein: each of the plurality of mounting grooves is defined by a groove front end wall, groove side walls, a groove rear end wall, and a groove bottom wall; the support frame further comprises a supporting cantilever, a free end of the supporting cantilever being provided with a return-blocking portion; and the return-blocking portion and the groove front end wall are arranged apart and to be block-fittable with the retainer, respectively. ### Claim 4 (depends on 3) The electrical connection assembly according to claim 3, wherein: at least one of the groove side walls is provided with a backstop arm; and the backstop arm is configured to protrude and extend into the mounting groove and to be block-fittable with the retainer. ### Claim 5 (depends on 4) The electrical connection assembly according to claim 4, wherein: one or two side walls of the retainer are provided with a blocking step; and the blocking step is configured to be block-fittable with the backstop arm. ### Claim 6 (depends on 4) The electrical connection assembly according to claim 4, wherein: the groove front end wall and the groove rear end wall are arranged apart along a longitudinal direction of the retainer; and the distance between the groove rear end wall and the backstop arm is greater than or equal to a longitudinal length of the retainer. ### Claim 7 (depends on 1) The electrical connection assembly as recited in claim 1, further comprising a circuit board, wherein the second protruding end portions electrically connect to the circuit board.
