[0033] An embodiment of the present application provides an electrical connector, which includes a female end structure and a male end structure 1. The male end structure 1 is plugged into the female end structure to achieve electrical conduction for transmitting electrical energy and / or electrical signals.

[0034] See also Figures 1 to 3 , an embodiment of the present application provides a male end structure 1, the male end structure 1 includes a support component 10 and an electrical contact piece 20. The support component 10 includes a support shaft 100 and a sleeve 200, the outer periphery of the support shaft 100 is provided with a mounting groove 101, and the mounting groove 101 is provided with two limiting walls 102 arranged opposite to each other in the axial direction O. The electrical contact piece 20 passes through the mounting groove 101 and abuts against the two limiting walls 102 respectively. Among them, the sleeve 200 is sleeved on the support shaft 100 and covers at least part of the mounting groove 101 to crimp the electrical contact piece 20. Part of the area of ​​the electrical contact piece 20 is exposed in the mounting groove 101 and the sleeve 200, so as to contact the female end structure and be electrically conductive with the female end structure.

[0035] In the male end structure 1, the mounting groove 101 is provided with two limiting walls 102 arranged opposite to each other in the axial direction O, and the electric contact piece 20 is respectively in contact with the two limiting walls 102, so that the position of the electric contact piece 20 in the axial direction O can be limited by the two limiting walls 102. In addition, the sleeve 200 is sleeved on the support shaft 100 and can press the electric contact piece 20, so that the electric contact piece 20 is pressed tightly in the mounting groove 101, thereby achieving the fixation of the electric contact piece 20. Compared with the traditional technology that uses the interference fit method to fix, the present application uses the limit on the structure to fix the electric contact piece 20, and the fixing method is more stable and not easy to loosen and fall off.

[0036] It is understandable that the electrical contact piece 20 is inserted into the mounting groove 101, so the electrical contact piece 20 can be stably positioned in the mounting groove 101 by being limited by the groove wall of the mounting groove 101. In addition, the sleeve 200 is sleeved on the support shaft 100 and can also press the electrical contact piece 20, thereby reducing the probability of the electrical contact piece 20 coming out of the mounting groove 101, so as to stably limit the position of the electrical contact piece 20.

[0037] See also Figure 3 and Figure 4 In one embodiment, the support shaft 100 includes a first shaft section 110 and a second shaft section 120, and the first shaft section 110 and the second shaft section 120 are connected end to end in the axial direction O. The limiting wall 102 is divided into a first limiting wall 112 and a second limiting wall 122, the first limiting wall 112 is arranged on the first shaft section 110, and the second limiting wall 122 is arranged on the second shaft section 120. In other words, the first shaft section 110 is used to abut against one side of the electrical contact piece 20, and the second shaft section 120 is used to abut against the other side of the electrical contact piece 20, and the two cooperate to limit the position of the electrical contact piece 20 in the axial direction O. It can be understood that since the electrical contact piece 20 is arranged in the mounting groove 101 of the support shaft 100 and axially abuts against the limiting wall 102 of the mounting groove 101, and the sleeve 200 is sleeved outside the electrical contact piece 20, it is difficult to complete the installation of the electrical contact piece 20 by simple axial plug-in. In this embodiment, the support shaft 100 is configured as a split design, so the electrical connector 20 can be conveniently installed in the installation groove 101 before the first shaft section 110 and the second shaft section 120 are assembled and installed.

[0038] Furthermore, the mounting groove 101 can be extended to the first shaft segment 110 and the second shaft segment 120 , that is, the first shaft segment 110 and the second shaft segment 120 are provided with corresponding groove portions (the first groove segment 111 and the second groove segment 121 mentioned below), which are connected to form the mounting groove 101 .

[0039] Please continue reading Figure 3 and Figure 4In one embodiment, the electrical connector 20 includes a crimping section 23 and an angle section 22. The crimping section 23 passes through the mounting groove 101 and abuts against the sleeve 200. The angle section 22 is connected to the crimping section 23 and is bent or curved relative to the crimping section 23 to abut against one of the limiting walls 102. In other words, the electrical connector 20 is not limited to abutting against the limiting wall 102 by its end. Part of the area of ​​the electrical connector 20 can be bent or curved to form an angle shape, and abut against the limiting wall 102 by the angle section 22. With such a configuration, on the one hand, Figure 3 As shown, the electrical connector 20 is a lamellar structure, and the angled section 22 is bent or folded relative to the crimping section 23 so that the electrical connector 20 and the limiting wall 102 can have a larger contact surface area, thereby improving the limiting stability. On the other hand, the angled section 22 can extend along the limiting wall 102 to the outside of the mounting groove 101 to be electrically connected to the conductive wire for transmitting electrical energy and electrical signals. It can be understood that the electrical connector 20 of the male end structure 1 is used to contact and electrically connect with the corresponding conductive part of the female end structure, and the tail of the electrical connector 20 also needs to be electrically connected to components such as conductive wires to transmit electrical energy and electrical signals to the device, equipment, etc. connected to the male end structure 1.

[0040] Of course, the electrical connector 20 is not limited to being configured to have the above-mentioned curved section 22 to extend outward from the mounting slot 101 to connect with the conductive wire. When the electrical connector 20 extends linearly, the electrical connector 20 can also be connected with the conductive wire. For example, see Figure 5 The limiting wall 102 may be configured with an opening (not shown in the figure, the same below), and the electrical contact piece 20 is provided with a region with a sudden change in width, thereby forming a transversely protruding wing 26. The wing 26 abuts against the limiting wall 102, and the relatively narrow part passes through the installation groove 101 through the opening to be connected with the conductive wire.

[0041] Please continue reading Figure 3 and Figure 4 In one embodiment, the sleeve 200 includes a limiting strip 210 and a ring sleeve 220, and the ring sleeve 220 is sleeved on the support shaft 100. The limiting strip 210 is inserted into the installation groove 101 to cooperate with the bottom wall of the installation groove 101 to clamp the crimping section 23 and the limiting wall 102 to clamp the angle section 22. The limiting strip 210 is inserted into the installation groove 101 and can cooperate with the groove wall of the installation groove 101 to position the circumferential position of the sleeve 200. In addition, the limiting strip 210 is also used to abut the crimping section 23 and press the angle section 22 against the limiting wall 102 to further improve the position stability of the electrical contact 20.

[0042] Furthermore, the ring sleeve 220 can be sleeved on the second shaft segment 120. The angle segment 22 can be located on the first shaft segment 110, and the angle segment 22 is used to abut against the first limiting wall 112. In other words, the limiting strip 210 is inserted into the mounting groove 101 and abuts against the side of the angle segment 22 that is away from the first limiting wall 112. The limiting strip 210 cooperates with the first limiting wall 112 to clamp the angle segment 22, so as to improve the position stability of the electrical contact 20.

[0043] See also Figure 3 and Figure 4 In one embodiment, the installation groove 101 includes a first groove section 111 and a second groove section 121. The first groove section 111 is arranged on the first shaft section 110, and the second groove section 121 is arranged on the second groove section 121. The first groove section 111 and the second groove section 121 can both extend along the axial direction O of the male end structure 1, and the first groove section 111 and the second groove section 121 are butted in the axial direction O to form the installation groove 101 as described above.

[0044] See also Figure 6 , Figure 7 Combined with Figure 3 and Figure 4 , the first shaft section 110 is provided with a first plug hole 113 along the axial direction O, and the first slot section 111 extends into the first plug hole 113. One end of the limiting strip 210 is connected to the ring sleeve 220, and the other end of the limiting strip 210 is plugged into the first plug hole 113. Thus, the position of the free end of the limiting strip 210 can be limited by the first plug hole 113, thereby improving the stability of the position of the sleeve 200. It can be understood that the first limiting wall 112 is a part of the first slot section 111 that is enclosed and formed, and the first limiting wall 112 is located in the first plug hole 113, and the limiting strip 210 is passed through the first plug hole 113 and presses the angle section 22 against the first limiting wall 112.

[0045] See also Figure 7 In one embodiment, the first insertion hole 113 and the first slot section 111 are arranged in the same radial direction, and the first insertion hole 113 is arranged at the periphery of the arrangement position of the first slot section 111, that is, the radial dimension of the bottom wall of the first insertion hole 113 is greater than the radial dimension of the bottom wall of the first slot section 111. The first limiting wall 112 is connected between the bottom wall of the first slot section 111 and the bottom wall of the first insertion hole 113, and the first limiting wall 112 is also arranged in the first insertion hole 113. The electrical connector 20 also includes a first plug-in section 21, which is used to connect the conductive wire, and the first plug-in section 21 is connected to the angle section 22, and the first plug-in section 21 is plugged into the first insertion hole 113.

[0046] See also Figure 3 and Figure 4In one embodiment, the second shaft section 120 further includes a cover plate 123, which covers one end of the second slot section 121 to form a relatively closed second plug hole 124. The second limiting wall 122 is a part of the second plug hole 124, and the electrical connector 20 is plugged into the second plug hole 124 and abuts against the second limiting wall 122. Further, the electrical connector 20 includes a second plug section 25, which is plugged into the second plug hole 124.

[0047] Of course, the second limiting wall 122 is not limited to being the hole wall of the second plug hole 124. It will be mentioned below that part of the electrical contact piece 20 protrudes out of the mounting groove 101 through the avoidance opening 125. In another embodiment, the second limiting wall 122 can also be the inner wall of the avoidance opening 125, which is used to abut the protruding part of the electrical contact piece 20 (i.e., the contact section 24 mentioned below).

[0048] See also Figure 3 In one embodiment, the support component 10 is provided with a clearance opening 125 connecting the second slot section 121 with the outside, and an area of ​​the electric contact piece 20 protrudes radially outward and is exposed through the clearance opening 125 to be electrically connected with the female end structure. The cover plate 123 is a part of the clearance opening 125, that is, the clearance opening 125 is located in the area close to the second limiting wall 122. The electric contact piece 20 is elastic and can be movably inserted into the second plug hole 124. Therefore, when the electric contact piece 20 cooperates with the female end structure, the electric contact piece 20 has space for elastic deformation to improve the stability of the contact.

[0049] For the avoidance opening 125, please refer to Figure 3 It can be understood that the mounting groove 101 is provided on the outer periphery of the support shaft 100, and the mounting groove 101 is directly connected to the outside. However, the sleeve 200 is sleeved on the support shaft 100 to cover part of the mounting groove 101, and the part of the mounting groove 101 not covered forms a clearance opening 125 and is connected to the outside. In this embodiment, the sleeve 200 partially covers the mounting groove 101, so that the electrical contact 20 can be exposed to the mounting groove 101 through the clearance opening. In another embodiment, the sleeve 200 can completely cover the area where the mounting groove 101 is located, and the electrical contact 20 is exposed by opening a hole in the sleeve 200.

[0050] Please continue reading Figure 3 In one embodiment, the second slot section 121 includes a bottom wall located on a side away from the sleeve 200, and the electrical contact piece 20 is spaced apart from the bottom wall. It is easy to understand that the side of the electrical contact piece 20 away from the bottom wall faces outward and is used to contact the female end structure. Therefore, the electrical contact piece 20 is spaced apart from the bottom wall of the second slot section 121, so that the electrical contact piece 20 has a movable space to bend and deform toward the bottom wall of the second slot section 121 when contacting the female end structure.

[0051] See also Figure 4 In one embodiment, the second shaft section 120 includes an outer shaft portion 126 and an inner shaft portion 127, and the outer shaft portion 126 and the inner shaft portion 127 are connected end to end in the axial direction O. The outer diameter of the outer shaft portion 126 is greater than the outer diameter of the inner shaft portion 127, so as to form a step 128 therebetween. The inner shaft portion 127 is passed through the sleeve 200, and the step 128 abuts against the sleeve 200. Further, the inner shaft portion 127 is passed through the annular sleeve 220, and the step 128 abuts against the annular sleeve 220, and the step 128 and the first limiting wall 112 can clamp the sleeve 200 in opposite directions to limit the position of the sleeve 200 in the axial direction O. Further, the inner shaft portion 127 is used to contact and dock with the first shaft section 110.

[0052] See also Figure 4 , the area of ​​the electrical connector 20 protruding radially outward is recorded as the contact section 24. Along the axial direction O of the male end structure 1, the electrical connector 20 includes a first plug-in section 21, an angle section 22, a crimping section 23, a contact section 24 and a second plug-in section 25 in sequence. Among them, the first plug-in section 21 is plugged into the first plug hole 113. The angle section 22 is used to abut against the first limiting wall 112. A part of the crimping section 23 is inserted into the first slot section 111, and the sleeve 200 cooperates with the bottom wall of the first slot section 111 to clamp the part of the crimping section 23 located in the first slot section 111; the other part of the crimping section 23 is suspended in the second slot section 121. The contact section 24 is exposed to the sleeve 200 and the mounting groove 101 through the avoidance opening 125, and is used to be electrically connected to the female end structure. The second plug-in section 25 is plugged into the second plug hole 124 and abuts against the first limiting wall 112.

[0053] See also Figure 3 and Figure 4 In one embodiment, the male end structure 1 includes a plurality of electrical contacts 20, which extend along the axis of the support shaft 100 and are arranged at intervals in the circumferential direction around the axis of the support shaft 100. There are a plurality of mounting grooves 101, and the positions of the mounting grooves 101 match the positions of the electrical contacts 20. The axis of the support shaft 100 can also refer to the reference numeral O in the drawings of the specification.

[0054] See also Figure 4 and Figure 8 In one embodiment, the male end structure 1 further includes a fixing component 300, and the fixing component 300 includes a pin 310 and a pin shaft 320. One end of the pin 310 abuts against the second shaft segment 120, and the other end of the pin 310 penetrates the second shaft segment 120 along the axial direction O and extends to the first shaft segment 110. The pin shaft 320 penetrates the first shaft segment 110 along the radial direction and is plugged and fixed with the end of the pin 310 away from the second shaft segment 120. In this way, through the cooperation of the pin 310 and the pin shaft 320, the first shaft segment 110 and the second shaft segment 120 can be conveniently fixed.

[0055] See also Fig. 9 Furthermore, the first shaft section 110 is provided with a first fixing hole 114 in the radial direction. The pin 320 is hollow and has elastic properties. The pin 320 is provided with a contraction gap 321 extending along the axial direction O. When the pin 320 is inserted into the first fixing hole 114, it is squeezed by the hole wall of the first fixing hole 114, so that the pin 320 is elastically deformed in the direction of closing the contraction gap 321. In this way, based on the elastic recovery property of the pin 320 itself, the pin 320 always has a tendency to open in the first fixing hole 114 to closely abut against the hole wall of the first fixing hole 114, thereby improving the position stability of the pin 320.

[0056] The support shaft 100 is provided with a second fixing hole 129 along the axial direction O. The second fixing hole 129 extends from the first shaft section 110 to the second shaft section 120. The pin 310 is passed through the second fixing hole 129. Furthermore, the cross-sectional shape of the second fixing hole 129 is not limited to a standard circle. Figure 6 As shown, the cross-section of the second fixing hole 129 can be configured with a flat position to position the pin 310 so that the pin 310 can be inserted into the second fixing hole 129 in a posture that is convenient for plugging and fixing with the pin shaft 320.
