Referring to fig. 6, 9 and 10 to 13, the first electrical connector 1 can rotate relative to the second electrical connector 2 along a first rotation direction R1 from an initial mating state to a final mating state. In the initial mating state, the first mating surface 111 faces the second mating surface 211, the mating slot 116 of the first housing 11 receives the second housing 21, the relief recesses 114 respectively receive the elastic contact portions 221a of the second terminals 22, and when the first electrical connector 1 rotates along the first rotation direction R1 to the final mating state, the contact plates 121 of the first terminals 12 respectively contact the elastic contact portions 221a of the second terminals 22 in a laterally pressing manner. By the first terminals 12 and the second terminals 22 contacting each other in a lateral manner, the length dimension of the first electrical connector 1 and the second electrical connector 2 in the mating direction D can be reduced. In addition, in the first embodiment, the inner side surface 113a of each mating protrusion 113 and the contact plate 121 of each first terminal 12 extend obliquely in the first rotation direction R1 toward a direction away from the center of the mating slot 116, in other words, the contact plate 121 has a first end edge 121a and a second end edge 121b spaced apart from each other in the first rotation direction R1, the second end edge 121b is located in front of the first end edge 121a in the first rotation direction R1, and a second distance L2 between the second end edge 121b and the center point C of the first seat 11 is greater than a first distance L1 between the first end edge 121a of the contact plate 121 and the center point C of the first seat 11 (see fig. 6). The contact plate 121 of the first terminals 12 extending obliquely can prevent the second terminals 22 from buckling or breaking due to improper operation, and can also reduce the wear rate of the plating layers on the surfaces of the first terminals 12 and the second terminals 22 under the condition that the second terminals 22 are subjected to the same pressing amount, so as to increase the service life of the electrical connector assembly 10. In addition, the elastic arm 221 of each second terminal 22 extends along the first rotation direction R1, and the elastic contact portion 221a of each second terminal 22 is located at the end of the elastic arm 221. Thereby, when the first electrical connector 1 is rotated along the first rotation direction R1, the abutting protrusions 113 and the contact plates 121 of the first terminals 12 can move along the extending direction of the elastic arms 221 of the second terminals 22, so as to further reduce the probability of buckling or breaking of the elastic arms 221 of the second terminals 22 when the first electrical connector is rotated from the initial abutting state to the final abutting state.
In addition, the process of the electrical connector assembly 10 from the initial mating state to the final mating state is not limited to rotating the first electrical connector 1 in the first rotation direction R1, but the second electrical connector 2 may be rotated in a second rotation direction R2 opposite to the first rotation direction R1, or the first electrical connector 1 may be rotated in the first rotation direction R1 and the second electrical connector 2 may be rotated in the second rotation direction R2 at the same time, which is not limited thereto. In addition, in the first embodiment, the first rotation direction R1 is counterclockwise and the second rotation direction R2 is clockwise, but in a modified embodiment, the first rotation direction R1 can be clockwise and the second rotation direction R2 can be counterclockwise.
Referring to fig. 14 to 16, a difference between the second embodiment and the first embodiment of the electrical connector assembly 10 of the present invention is that in the second embodiment, each of the mating protrusions 113 has an extension arm 113b extending along the second rotation direction R2, the first housing 11 further has a plurality of first stoppers 118 respectively disposed at the ends of the extension arms 113b of the mating protrusions 113 and protruding toward the mating slot 116, it should be noted that in a variation, the mating protrusions 113 may not have the extension arms 113b, and at this time, the first stoppers 118 are directly disposed on the mating protrusions 113. The second seat 21 further has a plurality of receiving grooves 215 formed on the outer side surface 212 and configured to receive the first stoppers 118, and a plurality of second stoppers 216 respectively adjacent to the receiving grooves 215, the receiving grooves 215 have a first groove portion 215a communicating with the second abutting surface 211 and extending along the abutting direction D, and a second groove portion 215b communicating with the first groove portion 215a and extending along the first rotating direction R1 on the outer side surface 212, and the second groove portion 215b of the receiving grooves 215 has a stopper surface 215c located at a distal end and configured to abut against the first stoppers 118 in the first rotating direction R1. The second stopper 216 is adjacent to the first groove portion 215a and the second groove portion 215b, and the second stopper 216 is adjacent to the second abutting surface 211 than the second groove portion 215 b. During the process of mating the electrical connector assembly 10, the first groove 215a of the receiving groove 215 is used to avoid the first stopper 118, so that the first electrical connector 1 can move toward the second electrical connector 2 along the mating direction D to the initial mating state, when the first electrical connector 1 rotates from the initial mating state to the final mating state, the second groove 215b of the receiving groove 215 receives the first stopper 118, and the first stopper 118 and the second stopper 216 are stopped in the mating direction D, so as to prevent the first electrical connector 1 and the second electrical connector 2 from moving along the mating direction D and being separated from each other. In the second embodiment, the number of the first stoppers 118, the accommodating grooves 215, and the second stoppers 216 is four, but in other variations, the number of the first stoppers 118, the accommodating grooves 215, and the second stoppers 216 may be one, two, three, or more than five, which is not limited thereto.
In the second embodiment, a pushing surface 215d protruding outward than the first groove 215a is formed at the second groove 215b of the receiving groove 215, and the pushing surface 215d is used for pushing the first stopper 118 outward in the process that the first electrical connector 1 rotates relative to the second electrical connector 2 and the first stopper 118 enters the second groove 215b of the receiving groove 215, thereby making the first electrical connector 1 easier to stay in the initial mating state and the final mating state relative to the second electrical connector 2. Further, the second groove portion 215b of the receiving groove 215 further has a recessed groove 215e located between the stopping surface 215c and the pushing surface 215d, and in the final mating state, the recessed groove 215e of the receiving groove 215 correspondingly receives the first stopper 118, so as to further enhance the positioning of the first electrical connector 1 in the final mating state, and further enable a user to feel the touch or sound of the positioning. Through the corresponding matching of the first stopper 118, the accommodating recess 215 and the second stopper 216, the first electrical connector 1 can be positioned in the final mating state relative to the second electrical connector 2, thereby ensuring the working stability of the electrical connection between the first electrical connector 1 and the second electrical connector 2.
In summary, the electrical connector assembly 10 of the present invention can reduce the length dimension of the first electrical connector 1 and the second electrical connector 2 in the mating direction D by the first terminals 12 and the second terminals 22 contacting each other in a lateral manner. The contact plate 121 of the first terminals 12 extending obliquely can prevent the second terminals 22 from buckling or breaking due to improper operation, and can also reduce the wear rate of the plating layers on the surfaces of the first terminals 12 and the second terminals 22 under the condition that the second terminals 22 are subjected to the same pressing amount, so as to increase the service life of the electrical connector assembly 10. In addition, the first stopper 118, the receiving groove 215 and the second stopper 216 are correspondingly matched to position the first electrical connector 1 in the final mating state with respect to the second electrical connector 2, so as to ensure the working stability of the electrical connection between the first electrical connector 1 and the second electrical connector 2.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the contents of the patent specification should be included in the scope of the present invention.
