[0048] The electrical connector provided by the present invention includes a pin body 10, a wire crimping barrel 20, a fastener 30 and an elastic component.

[0049] Hereinafter, the specific structures of the above-mentioned components of the electrical connector according to the present embodiment will be described.

[0050] In this embodiment, if Figure 1 and Figure 2 As shown, the pin body 10 has a first connecting hole 11, which is formed as a blind hole structure opened at one end of the pin body 10 in the axial direction. The wire crimping barrel 20 is set at an angle to the pin body 10, that is, the axis of the wire crimping barrel 20 is set at an angle to the axis of the pin body 10 to form a bent electrical connector.

[0051] In this embodiment, if Figure 2 and Figure 4 As shown, the wire barrel 20 is provided with a second connecting hole 21 coaxially arranged with the first connecting hole 11; the fastener 30 is penetrated through the first connecting hole 11 and the second connecting hole 21 to abut the wire barrel 20 against one end of the pin body 10 in the axial direction, the outer wall of the fastener 30 and the inner wall of the first connecting hole 11 form a first connecting area, and the outer wall of the fastener 30 and the interior of the second connecting hole 21 form a second connecting area, the elastic component includes a first elastic member 41 arranged in the first connecting area and a second elastic member 42 arranged in the second connecting area, the first elastic member 41 abuts between the fastener 30 and the pin body 10, and the second elastic member 42 abuts between the fastener 30 and the wire barrel 20, so that the assembly of the fastener 30 with the pin body 10 and the wire barrel 20 includes a two-stage flexible connection formed in the first connecting area and the second connecting area respectively, which reduces the transfer contact resistance, thereby reducing the heat generation, achieving the effect of reducing the temperature rise, and thus meeting the use requirements of the high current connector.

[0052] In this embodiment, the expansion and contraction directions of the first elastic member 41 and the second elastic member 42 are both radial directions of the fastener 30 , so that one end of the first elastic member 41 and the second elastic member 42 in the radial direction can abut against the outer wall of the fastener 30 .

[0053] Specifically, in this embodiment, Figure 4 As shown, the first connecting hole 11 is formed as a stepped hole, and the stepped hole includes a first connecting portion 111 and a second connecting portion 112 arranged in sequence along the insertion direction of the fastener 30, wherein the radial dimension of the first connecting portion 111 is greater than the radial dimension of the second connecting portion 112 to ensure that the fastener 30 can smoothly extend into the first connecting hole 11, and the inner wall of the first connecting portion 111 is formed with an internal thread threadedly connected to the fastener 30, and the first connecting area is formed in the second connecting portion 112, that is, the first elastic member 41 is arranged on the inner wall of the second connecting portion 112, so that the fastener 30 and the pin body 10 are assembled in two different ways in the first connecting portion 111 and the second connecting portion 112. Compared with the existing threaded connection method in which only a screw is used to connect the wire barrel 20 and the pin body 10 respectively, the two-stage flexible connection in the first connecting area and the second connecting area can effectively reduce the transition contact resistance, so that the heat generated by the curved electrical connector at the transition is reduced, thereby achieving the effect of reducing the temperature rise.

[0054] Furthermore, in this embodiment, if Figure 4As shown, the inner wall of the first connecting hole 11 is formed with a concave first groove 1121, and the first groove 1121 is formed into an annular structure. The two ends of the first elastic member 41 in the axial direction are embedded in the first groove 1121, so that the first elastic member 41 is positioned in the axial direction. The middle part of the first elastic member 41 is formed into an arc-shaped structure protruding toward the fastener 30, so that the arc-shaped structure part on the first elastic member 41 can extend out of the first groove 1121 and abut against the outer wall of the fastener 30. In this embodiment, as Figure 5 As shown, the first elastic member 41 can be formed into a non-closed ring with an opening by a sheet structure, and the arc-shaped structure part of the first elastic member 41 as described above is provided with strip holes, and a plurality of strip holes are arranged at intervals along the circumference of the first elastic member 41.

[0055] In addition, a second concave groove 211 is formed on the inner wall of the second connecting hole 21, and the second groove 211 is formed into an annular structure. The two ends of the second elastic member 42 in the axial direction are embedded in the groove wall of the second groove 211, so as to realize the positioning of the second elastic member 42 in the axial direction. The middle part of the second elastic member 42 is formed into an arc-shaped structure protruding toward the fastener 30, so that the arc-shaped structure part on the second elastic member 42 can extend out of the second groove 211 and abut against the outer wall of the fastener 30. In this embodiment, the structure of the second elastic member 42 can be the same as that of the first elastic member 41.

[0056] Furthermore, in this embodiment, if Figure 2 , Figure 4 and Figure 6 As shown, the fastener 30 has an abutment portion 31 and a connection portion 32, the abutment portion 31 is arranged at one end of the fastener 30 away from the pin body 10, and the connection portion 32 extends outward from the end of the abutment portion 31 facing the pin body 10 to form a rod-like structure coaxially arranged with the first connecting hole 11, and a partial area on the rod-like structure is provided with an external thread that cooperates with the first connecting portion 111 as described above; except for the portion provided with the external thread, the surface roughness of the connection portion 32 is ≤0.8μm, thereby ensuring that the surface of the portion of the connection portion 32 that does not have a threaded connection function is smooth and flat, which is beneficial to improving the heat dissipation efficiency.

[0057] Furthermore, the abutment portion 31 is formed as a boss structure protruding outward from the circumferential side wall of the connecting portion 32, that is, the radial dimension of the abutment portion 31 is larger than the radial dimension of the connecting portion 32, so that the abutment portion 31 can press the wire barrel 20 toward the pin body 10, so that the first connecting hole 11 and the second connecting hole 21 are connected, ensuring the effective assembly of the fastener 30, the pin body 10 and the wire barrel 20. In this embodiment, the radial dimension of the second connecting hole 21 is larger than the radial dimension of the first connecting hole 11.

[0058] In a preferred embodiment, Figure 4As shown, the electrical connector also includes a protective member 50, which is formed into a cover-like structure, so that a groove is formed on the side of the protective member 50 facing the fastener 30, and the groove is interference fit with the fastener 30 so that the protective member 50 is covered on the outer wall of the abutment portion 31. A through hole 51 is provided on the protective member 50, so that the outside of the protective member 50 is connected to the abutment portion 31, which not only improves the creepage distance of the electrical connector and increases the withstand voltage of the electrical connector, but also makes the electrical connector shorter, reduces the volume of the electrical connector, and improves the applicable environmental range of the electrical connector. More importantly, since the area where the fastener 30 is located is a dense area of ​​heat transfer, the setting of the heat dissipation holes can effectively accelerate the dissipation of heat.

[0059] In addition, in this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the electrical connector also includes a transition sleeve 60, which is formed as a partial shell of the electrical connector. The transition sleeve 60 is formed as a cylindrical structure to cover the transition between the pin body 10 and the wire crimping barrel 20, so that the fastener 30 and part of the pin body 10 and part of the wire crimping barrel 20 are arranged inside the transition sleeve 60.

[0060] Preferably, the inner wall of the adapter sleeve 60 is provided with a first heat dissipation layer 61, and the first heat dissipation layer 61 may be a graphite patch, and the first heat dissipation layer 61 is arranged on the entire inner wall of the adapter sleeve 60 in a pasting manner instead of being arranged in a pasting manner, so as to accelerate the heat dissipation speed and improve the heat dissipation effect; in addition, Figure 1 As shown, the outer wall of the adapter sleeve 60 is provided with a heat dissipation groove 62, which extends along the axial direction of the fastener 30 to the two axial ends of the adapter sleeve 60. Multiple heat dissipation grooves 62 are arranged at intervals along the circumference of the adapter sleeve 60, thereby increasing the area of ​​the outer wall of the adapter sleeve 60, further accelerating the heat dissipation speed and improving the heat dissipation effect, so that the first heat dissipation layer 61 inside the adapter sleeve 60 and the external heat dissipation grooves 62 can work together to improve the heat dissipation capacity, thereby ensuring the reliability and effectiveness of the electrical connector as a low temperature rise and high current connector.

[0061] Preferably, the cross section of the heat dissipation groove 62 perpendicular to the length direction thereof is formed into a V-shape, thereby further increasing the area of ​​the heat dissipation groove 62 and improving the heat dissipation capacity.

[0062] In this embodiment, if Figure 1 , Figure 2 and Figure 4As shown, the electrical connector further includes an end cap 70, which is connected to the transfer sleeve 60. Specifically, the end cap 70 is arranged at one end of the fastener 30 away from the pin body 10 to close the transfer sleeve 60, and the end cap 70 can be connected to the transfer sleeve 60 by screws. Preferably, the inner wall of the end cap 70 is provided with a second heat dissipation layer 71, so that the area where the fastener 30 is located (i.e., the dense area of ​​transfer heat generation) is completely covered by the first heat dissipation layer 61 and the second heat dissipation layer 71 that help to improve the heat dissipation effect. The second heat dissipation layer 71 can also be a graphite patch, and can also be attached to the inner wall of the end cap 70 by bonding.

[0063] In addition, in this embodiment, Figure 2 As shown, a first plug-in portion 12 is formed at the end of the pin body 10 in the axial direction; the first connecting hole 11 and the first plug-in portion 12 are arranged at both ends of the pin body 10 in the axial direction.

[0064] Furthermore, in this embodiment, if Figure 2 and Figure 3 As shown, the electrical connector further comprises a socket body 80, and the socket body 80 is formed with a first plug-in slot 81 connected with the pin body 10, so that the pin body 10 and the socket body 80 form a plug-in matching mode, specifically, the circumferential inner wall of the first plug-in slot 81 is connected with the circumferential outer wall of the pin body 10 to form a primary connection; the end of the first plug-in portion 12 is formed with a recessed second plug-in slot 121, and the socket body 80 is formed with a second plug-in portion 82 extending into the second plug-in slot 121, so that the pin body 10 can be inserted into the socket body 80 and the socket body 80 can also be inserted into the pin body 10 when in a plugged state, so as to form a secondary connection on the basis of the primary connection, so as to realize that the socket body 80 and the pin body 10 can be inserted into each other, so as to ensure that the plug and the socket of the electrical connector can be locked firmly, and meet the use requirements of vibration and other working conditions. It should be noted that, as described above, the plug comprises the pin body 10, and the socket comprises the socket body 80.

[0065] Furthermore, in this embodiment, if Figure 3As shown, the elastic component also includes a third elastic member 43, which is arranged between the inner wall of the first plug-in slot 81 and the outer wall of the first plug-in portion 12 in the circumferential direction, so that the first plug-in slot 81 and the first plug-in portion 12 are crimped. Specifically, the inner wall of the first plug-in slot 81 is formed with a first limiting portion 811 protruding inward at the end in the axial direction. The first limiting portion 811 can be formed as an annular structure and is arranged at the notch of the first plug-in slot 81. The third elastic member 43 is embedded between the first limiting portion 811 and the slot wall of the first plug-in slot 81 in the axial direction, so that the axial direction of the third elastic member 43 is limited to prevent the third elastic member 43 from moving in the axial direction. In this embodiment, the telescopic direction of the third elastic member 43 is the radial direction of the pin body 10, and the structure of the third elastic member 43 can be the same as that of the first elastic member 41.

[0066] In this embodiment, if Figure 3 As shown, the elastic component also includes a fourth elastic member 44, which is arranged between the second plug-in slot 121 and the second plug-in portion 82. The second plug-in slot 121 has an inwardly protruding second limiting portion 1211 formed at the axial end thereof. The fourth elastic member 44 is embedded between the second limiting portion 1211 and the axial slot wall of the second plug-in slot 121. The second plug-in portion 82 abuts against the fourth elastic member 44. The expansion and contraction direction of the fourth elastic member 44 is the axial direction of the pin body 10. In this way, the axial electrical connection between the pin body 10 and the socket body 80 is achieved through the fourth elastic member 44, which can further enhance the locking force of the plug and the socket, reduce the contact resistance, and reduce the heat generation, thereby enhancing the effect of reducing the temperature rise.

[0067] According to the electrical connector of the present invention, a first connecting hole is arranged on the pin body and a second connecting hole is arranged on the wire barrel arranged at an angle to the pin body, and a first connecting area and a second connecting area are formed by assembling a fastener with the first connecting hole and the second connecting hole, and a first elastic member is arranged in the first connecting area and a second elastic member is arranged in the second connecting area. The assembly of the fastener, the pin body and the wire barrel includes a two-stage flexible connection formed in the first connecting area and the second connecting area, which reduces the switching contact resistance, thereby reducing the heat generation, achieving the effect of reducing the temperature rise, and thus meeting the use requirements of the high current connector.
