[0002] A traditional movable electrical connector combination includes a first connector and a second connector that are paired with each other. The first connector has a first body and a first terminal, and the second connector has a second body and a second terminal. The first body includes a fixed base fixed on a circuit board and a movable base movable relative to the fixed base. The first terminal is elastic and connects the fixed base and the movable base, so that it is suitable for use in a vibrating environment. When the movable connector combination is in a vibrating environment, the movable base can absorb vibration, thereby maintaining electrical contact between the first terminal and the second terminal.

[0003] In both the insertion and removal directions of the first and second connectors, as well as in directions intersecting the insertion and removal directions, the movable base can achieve positional change by elastically deforming the first terminal, thereby absorbing vibration. Simultaneously, the contact portions of the first and second terminals slide relative to each other, maintaining electrical continuity. However, because the first terminal can deform under external forces, its positional stability and elasticity requirements are high, and existing first terminals still have shortcomings in this regard.

[0004] In view of this, it is necessary to improve the existing movable electrical connector assembly to solve the above problems. Utility Model Content

[0026] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all within the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 11The figure shows a preferred embodiment of the movable electrical connector assembly of the present invention. In this embodiment, the movable electrical connector assembly includes a first connector 100 and a second connector 200 that are mated with each other. Figures 1 to 8 The preferred embodiment of the first connector 100 of the present invention is shown. Figures 9 to 11 A preferred embodiment of the second connector 200 of the present invention is shown.

[0028] For ease of explanation, when introducing a single first connector 100 or second connector 200 below, the docking ends of the first connector 100 and the second connector 200 will be regarded as the top end and the other end opposite to each other will be regarded as the bottom end. That is, the up and down directions are the docking directions of the first connector 100 and the second connector 200. At the same time, a direction perpendicular to the up and down directions is defined as the first direction, and another direction perpendicular to the up and down directions is defined as the second direction.

[0029] The first connector 100 includes a first body 11 and a first terminal 12 fixed to the first body 11 . The second connector 200 includes a second body 21 and a second terminal 22 fixed to the second body 21 .

[0030] Please refer to Figures 1 to 8 As shown, the first body 11 includes a fixed base 112 and a movable base 113 that can move relative to the fixed base 112, the movable base 113 has a bottom wall 1131, a pair of limiting walls 1132 protruding from the bottom wall 1131 and a central protrusion 1134 located between the pair of limiting walls 1132, an insertion space 1130 is formed between each of the limiting walls 1132 and the central protrusion 1134, the central protrusion 1134 has a plurality of first terminal grooves 1135 respectively connected to the insertion spaces 1130 on both sides thereof and a stop wall 1136 covering the top of the first terminal groove 1135.

[0031] The first terminal 12 has a contact arm 121 inserted and fixed in the corresponding first terminal groove 1135 and a top portion 122 located on the upper side of the contact arm 121. The top portion 122 is bent in a direction away from the insertion space 1130 to form a curved shape. The side of the top portion 122 facing the insertion space 1130 is covered by the stop wall 1136. In this way, since the height of the contact arm 121 in the up and down directions is relatively large, the top end of the first terminal 12 is limited to the inner side of the stop wall 1136 to prevent the first terminal 12 from tilting toward the insertion space 1130. At the same time, it is also beneficial to the insertion of the top end of the first terminal 12 to prevent the top end 122 from overflowing out of the first terminal groove 1135 during insertion.

[0032] In addition, further, in a preferred embodiment of the present invention, the width of the top portion 122 in the second direction is less than half the width of the contact arm 121 , so as to facilitate the bending and forming of the top portion 122 and facilitate the insertion of the first terminal 12 .

[0033] The first terminal 12 further includes an elastic connecting arm 123. The contact arm 121 includes an interference section 1211 located on its lower side and fixed to the movable base 113, and a stopper 1212 that abuts against the movable base 113. A step 11351 is provided in the first terminal slot 1135 to abut against the stopper 1212 to prevent the contact arm 121 from being excessively inserted upward.

[0034] The connecting arm 123 includes a first connecting segment 1231 extending downward from the bottom end of the interference segment 1211. The width of the first connecting segment 1231 in the second direction is less than one-third of the width of the stop portion 1212. In addition, the connecting arm 123 also includes a transverse segment 1232 connected to the bottom end of the first connecting segment 1231, a second connecting segment 1233 extending upward from the end of the transverse segment 1232, and a third connecting segment 1234 extending upward from the first fixing portion 124. The top end of the second connecting segment 1233 is connected to the top end of the third connecting segment 1234, and the length of the second connecting segment 1233 is greater than the length of the third connecting segment 1234.

[0035] The first terminal 12 further includes a first fixing portion 124 fixed in the fixing base 112 and a first solder foot 125 connected to an external circuit board (not shown). The connecting arm 123 connects the first fixing portion 124 to the contact arm 121 .

[0036] The first connector 100 has two rows of first terminals 12 arranged opposite to each other in a first direction, and each row of first terminals 12 is arranged in a second direction perpendicular to the first direction. The contact arm 121 is provided with convex bumps 1213 protruding on both sides thereof in the second direction, and the convex bumps 1213 are located on the upper side of the interference section 1211.

[0037] The bottom end of the central protrusion 1134 is connected to the bottom wall 1131. The bottom wall 1131 is provided with a plurality of through slots 1137 formed therethrough in the up and down directions. The through slots 1137 are connected to the corresponding first terminal slots 1135 to facilitate the positioning and removal of the molding die.

[0038] The movable base 113 is provided with a plurality of protrusions 1138 protruding from its bottom. These protrusions 1138 are arranged along the second direction. Each protrusion 1138 extends along the first direction and is located between two adjacent first terminals 12 in the second direction. This increases the arc creepage distance between the two adjacent first terminals 21, thereby preventing arc discharge and fire. Furthermore, each protrusion 1138 does not extend beyond the extension of the through-slot 1137 in the first direction. Furthermore, each protrusion 1138 is located above the transverse section 1232 of the connecting arm 123.

[0039] Each limiting wall 1132 is provided with a first recessed portion 1141 communicating with the corresponding insertion space 1130. This first recessed portion 1141 is formed from the side of the limiting wall 1132 facing the central protruding wall 1134 toward the side away from the central protruding wall 1134. This provides sufficient clearance for the second connector 200 to prevent interference caused by floating in a vibrating environment. Furthermore, the movable base 113 also has a pair of end walls 1139 connecting the pair of limiting walls 1132. Each end wall 1139 is provided with a second recessed portion 1140, recessed downward from its top, to facilitate injection molding.

[0040] The first recessed portion 1141 extends from the top end of the limiting wall 1132 to the bottom end of the limiting wall 1132 , and the recessed depth of the first recessed portion 1141 gradually decreases from top to bottom.

[0041] The recessed depth of the first recessed portion 1141 in the second direction gradually decreases, that is, the recessed depth of the first recessed portion 1141 on the upper side is greater than that on the lower side, thereby providing a larger clearance space on the upper side to avoid interference with the second body 21.

[0042] Please refer to Figures 9 to 11 As shown, the second connector 200 also has a plurality of fixing members 23 installed on its second body 21. The fixing members 23 are placed on both sides of the second terminal 22 in the second direction, and there are two fixing members 23 distributed on each side of the second terminal 22 in the second direction. The two fixing members 23 are spaced apart and opposite to each other along the first direction.

[0043] Furthermore, if Figure 11As shown, the second terminal 22 includes a second fixed portion 221 and first and second elastic arms 223 and 224 extending from the second fixed portion 221. The first and second elastic arms 223 and 224 successively elastically contact the contact arm 121, and the first and second elastic arms 223 and 224 are in contact with the contact arm 121 in their entire width direction. Specifically, the width direction of the first and second elastic arms 223 and 224 is perpendicular to the material thickness direction, and the width direction is the same as the second direction. The first elastic arm 223 is in contact with the contact arm 121 in its entire width direction, thereby ensuring the contact area with the contact arm 121 and improving the reliability of the electrical contact.

[0044] The second terminal 22 also has a base portion 225 extending from the second fixing portion 221 and a second solder foot 226 bent from the second fixing portion 221 to be flatly attached to another external circuit board. The second elastic arm 224 is located in an O-shaped frame formed by connecting the base portion 225 and the second fixing portion 221, and the first elastic arm 223 is bent from the top end of the base portion 225.

[0045] The movable electrical connector assembly 100 of the present invention is configured by providing a top portion 122 located on the upper side of the contact arm 121 on the elastic first terminal 12, and forming the top portion 122 into a curved shape that is bent in a direction away from the plug-in space 1130. The side of the top portion 122 facing the plug-in space 1130 is covered by the stop wall 1136, thereby limiting the top of the first terminal 12 to prevent the top of the first terminal 12 from tilting up, which would cause difficulty in plugging in or even structural damage, thereby making the structure of the movable electrical connector assembly stable and having a strong vibration absorption capability.
