For example, the second operating component 134 can be a sliding sleeve slidable relative to the second inserting component 131.

[0022] In this embodiment, the second cooperating structure 114 is located between the first cooperating structure 112 and the fixing end 111B of the receiving component 111 along the length direction L of the receiving component 111.

[0023] Besides, the multipurpose receptacle electrical connector 11 further includes a pushing structure 115 protruding from the outer wall of the receiving component 111 and located between the inserting end 111A of the receiving component 111 and the second cooperating structure 114 along the length direction L of the receiving component 111.

An abutment of the transition platform 117 and the end portion of the first inserting component 121 of the first plug electrical connector 12 can provide a sealing effect for keeping terminals of the multipurpose receptacle electrical connector 11 and the first plug electrical connector 12 away from environmental dust and/or moisture, so as to protect the terminals of the multipurpose receptacle electrical connector 11 and the first plug electrical connector 12. An abutment of the abutting protruding platform 116 and the end portion of the first inserting component 121 of the first plug electrical connector 12 can prevent any relative vibration of the first plug electrical connector 12 and the multipurpose receptacle electrical connector 11, so as to secure the mating of the multipurpose receptacle electrical connector 11 and the first plug electrical connector 12.

[0027] When the multipurpose receptacle electrical connector 11 and the second plug electrical connector 13 are mated with each other, the abutting protruding platform 116 and the transition platform 117 are configured to abut against an end portion of the second inserting component 131 of the second plug electrical connector 13. An abutment of the transition platform 117 and the end portion of the second inserting component 131 of the second plug electrical connector 13 can provide a sealing effect for keeping terminals of the multipurpose receptacle electrical connector 11 and the second plug electrical connector 13 away from environmental dust and/or moisture, so as to protect the terminals of the multipurpose receptacle electrical connector 11 and the second plug electrical connector 13. An abutment of the abutting protruding platform 116 and the end portion of the second inserting component 131 of the second plug electrical connector 13 can prevent any relative vibration of the second plug electrical connector 13 and the multipurpose receptacle electrical connector 11, so as to secure the mating of the multipurpose receptacle electrical connector 11 and the second plug electrical connector 13.

[0028] Preferably, as shown in FIG. 3 and FIG. 4, in order to achieve the abutting protruding platform 116 and the transition platform 117 to abut against the end portion of the first inserting component 121 and the end portion of the second inserting component 131 for providing the aforementioned sealing and vibration-proof effects, an inner chamber diameter D2 defined by the transition platform 117 can be greater than an inner chamber diameter defined by the abutting protruding platform 116 and be within the range of 12.1 to 12.5 millimeters, and a distance H2 between an interface of the transition platform 117 and the abutting protruding platform 116 and the end surface of the inserting end 111A can be within the range of 4.2 to 4.3 millimeters.

[0029] It should be noticed that the multipurpose receptacle electrical connector 11 can be manufactured by cutting stainless steel, such that multipurpose receptacle electrical connector 11 can not only comply with the aforementioned dimensional specifications but also have enhanced structural strength.

[0030] Please further refer to FIG. 7. FIG. 7 is a diagram of a multipurpose receptacle electrical connector 11' and a third plug electrical connector 14' mated with each other according to another embodiment of the present invention. As shown in FIG. 7, the multipurpose receptacle electrical connector 11' of this embodiment is similar to the multipurpose receptacle electrical connector 11 of the aforementioned embodiment. Different from the aforementioned embodiment, the multipurpose receptacle electrical connector 11' of this embodiment is compatible with not only the first plug electrical connector and the second plug electrical connector but also the third plug electrical connector 14' different from the first plug electrical connector and the second plug electrical connector. The multipurpose receptacle electrical connector 11' and at least one of the first plug electrical connector, the second plug electrical connector and the third plug electrical connector 14' can form an electrical connector assembly 1' cooperatively. Specifically, the multipurpose receptacle electrical connector 11' further includes a third cooperating structure 118' formed on an abutting protruding platform 116' and configured to engage with a screw structure 142' of the third plug electrical connector 14' in a screwing manner when a receiving component 111' at least partially receives a third inserting component 141' of the third plug electrical connector 14'. For example, the screw structure 142' can be an outer threaded structure different from the inner latch structure and the outer latch structure, and the third cooperating structure 118' can be an inner threaded structure matched with the screw structure 142'. Other details of this embodiment are the same as the ones of the aforementioned embodiment, and have similar variations. Detailed description is omitted herein for simplicity.
