[0057] Please refer to Figure 2 as well as Figures 4 to 8 As shown, the electrical connector 200 includes a first body 4, a conductive unit, a cable 6 secured to the conductive unit, a second insulating body 7 mating with the first body 4, and an unlocking spring 8 mounted on the first body 4. In the illustrated embodiment of the present invention, the first body 4 is a first insulating body, i.e., it is made of an insulating material. In the illustrated embodiment of the present invention, the conductive unit is a built-in circuit board 5. Of course, in other embodiments, the conductive unit may also be a conductive terminal, etc.

[0058] The first body 4 includes a main body 43, a first side wall 41 located on one side of the main body 43, a second side wall 42 located on the other opposite side of the main body 43, a top wall 44 extending from the top of the main body 43 in a first direction A1-A1 (e.g., a front-to-back direction), and a docking space 401 located at the front end of the main body 43.

[0061] Please combine Figures 6 to 12As shown, in one embodiment of the present invention, the unlocking spring 8 is made of metal material and is roughly U-shaped. The unlocking spring 8 includes a fixing portion 81, a locking portion 82 spaced apart from the fixing portion 81, a connecting portion 83 connecting one end of the fixing portion 81 and one end of the locking portion 82, a force-bearing portion 86 connecting the locking portion 82, a connecting arm 84, a support arm 85 connected to the locking portion 82, and a force-bearing portion 86 connected to the connecting arm 84 and the support arm 85. The support arm 85 is located beside the connecting arm 84 along the second direction A2-A2 (for example, the left-right direction), and the support arm 85 and the connecting arm 84 are staggered along the first direction A1-A1. The second direction A2-A2 is perpendicular to the first direction -A1. In the illustrated embodiment of the present invention, the fixing portion 81, the connecting portion 83 and the locking portion 82 are U-shaped as a whole. The fixing portion 81 and the locking portion 82 are located on the same side of the connecting portion 83. The fixing portion 81 is fixed to the mounting groove 4421 of the first body 4. The locking portion 82 is provided with at least one locking component 821 (e.g., a locking protrusion), which is configured to lock with the locking hole 311 of the docking connector 100. In the illustrated embodiment of the present invention, there are two locking components 821, which are spaced apart along the second direction A2-A2. In the illustrated embodiment of the present invention, the two locking components 821 are integrally stamped from the locking portion 82 and are aligned along the second direction A2-A2. The force-bearing portion 86 can directly or indirectly drive the locking portion 82 to move closer to the fixing portion 81 (i.e., elastically deform toward the space 80) under the action of an external force, thereby disengaging the locking component 821 from the locking hole 311 of the docking connector 100 to achieve unlocking. In the illustrated embodiment of the present invention, the connecting portion 83 is arc-shaped to better support the deformation of the locking portion 82. The support arm 85 is configured to increase the rigidity of the locking portion 82 to reduce the risk of unlocking failure due to insufficient deformation. Of course, those skilled in the art will understand that the locking protrusion and the locking hole 311 can also be swapped, that is, the locking component 821 is the locking hole 311, and it is provided on the locking portion 82; the locking protrusion that cooperates with the locking hole 311 is provided on the docking connector 100.

[0062] In the illustrated embodiment of the present invention, the locking portion 82 is spaced apart from the fixing portion 81 along a third direction A3-A3 (e.g., a vertical direction), wherein the locking portion 82 is located above the fixing portion 81. The unlocking spring 8 includes a space 80 between the locking portion 82 and the fixing portion 81. The third direction A3-A3 is perpendicular to the first direction A1-A1 and the second direction A2-A2.

[0063] In the illustrated embodiment of the present invention, the connecting arm 84 and the supporting arm 85 are both connected between the locking portion 82 and the force-bearing portion 86. The supporting arm 85 includes a first supporting arm 851 and a second supporting arm 852, wherein the first supporting arm 851 and the second supporting arm 852 are located on both sides of the connecting arm 84 along the second direction A2-A2.

[0064] In the illustrated embodiment of the present invention, the first support arm 851, the second support arm 852, and the connecting arm 84 are all arranged at an angle, wherein the first support arm 851 and the second support arm 852 are both farther away from the connecting portion 83 than the connecting arm 84. In other words, in the illustrated embodiment of the present invention, the first support arm 851 and the second support arm 852 are both located at the rear end of the connecting arm 84 along the first direction A1-A1.

[0065] Specifically, the first support arm 851 includes a first end 8511 connected to the locking portion 82 and a second end 8512 connected to the force-bearing portion 86. The second support arm 852 includes a third end 8521 connected to the locking portion 82 and a fourth end 8522 connected to the force-bearing portion 86. The connecting arm 84 includes a fifth end 841 connected to the locking portion 82 and a sixth end 842 connected to the force-bearing portion 86. The first end 8511 and the third end 8521 are both located at the rear end of the fifth end 841 along the first direction A1-A1, and the second end 8512 and the fourth end 8522 are both located at the rear end of the sixth end 842 along the first direction A1-A1.

[0066] In the illustrated embodiment of the present invention, the first end 8511, the third end 8521 and the fifth end 841 are located in the same first plane, the second end 8512, the fourth end 8522 and the sixth end 842 are located in the same second plane, and the second plane is higher than the first plane.

[0067] In the illustrated embodiment of the present invention, the width of the connecting arm 84 along the second direction A2-A2 is greater than the width of the first support arm 851 along the second direction A2-A2, and the width of the connecting arm 84 along the second direction A2-A2 is also greater than the width of the second support arm 852 along the second direction A2-A2. With this arrangement, when an external force acts on the force-bearing portion 86, the force-bearing portion 86 can transmit the force to the locking portion 82 through the relatively wide connecting arm 84, thereby causing the locking portion 82 to elastically deform into the space 80. At the same time, when the external force acts on the force-bearing portion 86, the force-bearing portion 86 can also transmit the force to the locking portion 82 through the relatively narrow first support arm 851 and the second support arm 852, thereby also causing the locking portion 82 to elastically deform into the space 80. The utility model sets the first support arm 851 and the second support arm 852 at the rear end of the connecting arm 84, so that the first support arm 851 and the second support arm 852 can be closer to the force-bearing part 86. When the force-bearing part 86 receives external force, the first support arm 851 and the second support arm 852 can form a balanced lever (please refer to the reference numerals for reference). Figure 11 As shown in FIG, the connection between the connecting arm 84 and the force-bearing portion 86 is improved, thereby improving the defect of elastic deformation. Ultimately, the external force applied to the force-bearing portion 86 can be effectively transmitted to the locking portion 82, causing the locking portion 82 to elastically deform, thereby reducing the risk of unlocking failure due to insufficient elastic deformation of the locking portion 82.

[0068] Please combine Figures 9 to 12 As shown, in the first embodiment of the unlocking spring 8 of the present invention, the unlocking spring 8 includes a first tearing opening 871 located along the second direction A2-A2 between the connecting arm 84 and the first support arm 851, and a second tearing opening 872 located along the second direction A2-A2 between the connecting arm 84 and the second support arm 852. The first support arm 851 and the second support arm 852 are integrally stamped from the unlocking spring 8, and the first support arm 851 and the second support arm 852 are torn from the unlocking spring 8.

[0069] Please combine Figures 17 to 20As shown, in the second embodiment of the unlocking spring 8 of the present invention, the first support arm 851 and the second support arm 852 are seamlessly connected to the connecting arm 84, wherein the unlocking spring 8 includes a first reinforcing side wall 881 located between the connecting arm 84 and the first support arm 851 along the second direction A2-A2, and a second reinforcing side wall 882 located between the connecting arm 84 and the second support arm 852 along the second direction A2-A2. The first support arm 851 and the second support arm 852 are integrally stamped from the unlocking spring 8, and the first support arm 851 and the second support arm 852 are not torn from the unlocking spring 8.

[0070] In addition, in the illustrated embodiment of the present invention, the force-bearing portion 86 includes a reinforcing rib 861 extending along the first direction A1 - A1 to increase the structural strength of the force-bearing portion 86 .

[0071] When unlocking is required, external force can be applied directly to the force-bearing portion 86 or by pulling a pull strap (not shown) connected to the force-bearing portion 86 to transfer the external force to the force-bearing portion 86. The force-bearing portion 86 transfers the external force to the locking portion 82 through the first support arm 851, the second support arm 852 and the connecting arm 84, and drives the locking portion 82 to move closer to the fixed portion 81 (for example, elastically deform downward), so that the locking component 821 is disengaged from the locking hole 311 of the docking connector 100 to achieve unlocking. The first support arm 851 and the second support arm 852 can form a balancing lever (please refer to the diagram for details). Figure 11 As shown in FIG, the connection between the connecting arm 84 and the force-bearing portion 86 is improved, thereby improving the defect of elastic deformation. Ultimately, the external force applied to the force-bearing portion 86 can be effectively transmitted to the locking portion 82, causing the locking portion 82 to elastically deform, thereby reducing the risk of unlocking failure due to insufficient elastic deformation of the locking portion 82.

[0072] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on technical personnel in the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, ordinary technical personnel in the field should understand that technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
