Here, up and down indicate the second direction and front and back represent the first direction for the convenience of introducing the specific embodiments of the present application. There is no absolute correspondence between the up and down directions and the second direction, and between the front and back directions and the first direction.

[0070] According to the first aspect of this application, reference Figures 1 to 11 , provides a connecting terminal 100 including a main body portion 110 , a plug portion 120 and a reinforcement portion 130 .

[0071] The connecting terminal 100 further includes a sheath housing 150 .

[0072] Part of the main body 110 and the reinforcement portion 130 are installed in the cavity of the sheath housing 150 , and the plug-in portion 120 is located outside the cavity of the sheath housing 150 .

[0073] The main body 110 is used to form an electrical connection with an external power source. The plug portion 120 is located at the front end of the main body 110 and is formed or connected to the main body 110 . The reinforcement portion 130 is formed or connected between the main body 110 and the plug portion 120 .

[0074] Through the above technical solution, the reinforcement part 130 can disperse the stress between the main body part 110 and the plug-in part 120, avoiding excessive concentration of stress in the part between the main body part 110 and the plug-in part 120, thereby improving the mechanical properties of the connecting terminal 100, avoiding the occurrence of crooked needles, and ensuring the structural stability of the connecting terminal 100.

[0075] Specifically, refer to Figure 3 The main body 110 includes a main structure 111, a retaining structure 112, a wire pressing structure 113 and a connecting structure 114.

[0076] The retaining structure 112 and the wire pressing structure 113 are formed to the main structure 111 , the wire pressing structure 113 is located at the rear end of the main structure 111 , and the connecting structure 114 is located at the front end of the main structure 111 .

[0077] Along the second direction, from top to bottom, the retaining structure 112 and the main structure 111 are partially overlapped.

[0078] The main structure 111 is an approximately box-like structure surrounded by an upper arm, a right arm, a left arm and a bottom arm. The retaining structure 112 includes a retaining spring 1121. The retaining spring 1121 is a cantilever structure extending backward from the upper connecting arm 1141. When the connecting terminal 100 is inserted into the cavity of the sheath shell 150, it provides a retaining force for the connecting terminal 100 so that the connecting terminal 100 can be retained in the cavity.

[0079] refer to Figure 3 The wire pressing structure 113 is arranged at the rear end of the main structure 111, and includes a front wire pressing segment 1131 and a rear wire pressing segment 1132. The front wire pressing segment is used to press with the conductor of the wire so that the connecting terminal 100 and the wire form electrical contact. The rear wire pressing segment 1132 is used to press with the insulation of the wire to provide sufficient holding force for the connecting terminal 100 and the wire.

[0080] refer to Figure 3 The plug-in portion 120 is arranged at the front end of the main structure 111 and includes a plug-in section 121 and a guide section 122 .

[0081] The plug section 121 is a nearly square structure surrounded by four walls. When the connecting terminal 100 is mated with the mating end, it can form a contact loop with the spring piece of the mating end to provide electrical contact.

[0082] The guide section 122 is provided at the front end of the plug-in section 121 , and is an inclined surface structure extending forward from two walls in the plug-in section 121 , and provides a guiding function when contacting with the mating end.

[0083] refer to Figure 3The connecting structure 114 includes connecting arms 1141. Three of the four connecting arms 1141 are arranged around the main body structure of the main body 110, wherein the upper connecting arm 1141 extends toward the rear end and tilts upward.

[0084] In some embodiments, reference Figures 3 to 5 The reinforcement portion 130 includes a strength transition structure 131 , a portion of which is formed or connected to the rear end of the plug-in portion 120 , and a portion of which is formed or connected to the front end of the main body portion 110 .

[0085] Specifically, part of the strength transition structure 131 is formed to the plug section 121 of the plug portion 120 , and part of the strength transition structure 131 is formed to the connecting arm 1141 of the connecting structure 114 of the main body 110 .

[0086] The strength transition structure 131 is utilized to achieve a smooth transition between the pin section and the connection structure 114 of the main body 110 , making stress distribution more uniform and avoiding stress concentration.

[0087] In some embodiments, reference Figures 3 to 5 The strength transition structure 131 includes a strength transition arm 1311 , which is arranged to be tilted relative to the first direction along a first direction from the plug-in portion 120 toward the main body portion 110 .

[0088] The strength transition arm 1311 is constructed as an arm extending backward along the first direction from the rear end of the plug-in section 121. The four arms form a strength transition structure 131 with a shape similar to a tetrahedron. The structure is stable and the method of enhancing strength is simple and easy to operate.

[0089] In some embodiments, reference Figures 3 to 5 , along the first direction, from front to back, the orthographic cross-sectional area of ​​the outer peripheral surface of the strength transition structure 131 in the first direction gradually increases.

[0090] Specifically, the orthographic cross-sectional area of ​​the outer peripheral surface of the strength transition structure 131 in the first direction gradually increases, that is, the tetrahedron formed by the four strength transition arms 1311 can be constructed as a tetrahedron, and the orthographic cross-sectional area of ​​the outer peripheral surface of the strength transition structure 131 in the first direction gradually increases, that is, when extending to the left along the first direction, the cross-sectional area of ​​the strength transition structure 131 gradually increases.

[0091] In some embodiments, reference Figures 3 to 5 , different strength transition arms 1311 are set in a smooth transition.

[0092] Specifically, different strength transition arms 1311 can be connected through transition R angles to form a complete structure.

[0093] In some embodiments, reference Figure 6and Figure 7 The strength transition structure 131 and the strength retention structure 132 of the reinforcement portion 130 are both located in the cavity of the sheath shell 150 , and the pin insertion portion is located outside the cavity of the sheath shell 150 .

[0094] In some embodiments, reference Figure 4 , the reinforcement portion 130 further includes a strength maintaining structure 132 .

[0095] Part of the strength maintaining structure 132 is formed or connected to the rear end of the strength transition structure 131 , and part of the strength maintaining structure 132 is formed or connected to the front end of the body portion 110 .

[0096] Specifically, a portion of the strength retaining structure 132 forms the rear end of the strength transition structure 131 , and a portion forms the front end of the connection structure 114 to the main body 110 .

[0097] The strength retaining structure 132 can be arranged in conjunction with the strength transition structure 131 to improve the strength between the main body of the connecting terminal 100 and the plug-in portion 120 and enhance the anti-bending capability.

[0098] In some embodiments, reference Figure 4 , the strength retention structure 132 includes a strength retention arm 1321.

[0099] The strength retaining arm 1321 is connected to the strength transition arm 1311 , and the strength retaining arm 1321 is arranged parallel to the first direction.

[0100] Specifically, the strength retaining arm 1321 is an arm extending to the left from the rear end of the strength transition arm 1311 along the first direction, and the strength retaining structure 132 is an approximately square structure composed of four arms. By arranging the strength retaining arm 1321 in parallel along the first direction, the bending resistance is improved.

[0101] In some embodiments, along the first direction, from front to back, the orthographic cross-sectional area of ​​the outer peripheral surface of the strength retention structure 132 in the first direction is uniformly arranged.

[0102] Specifically, from front to back, the outer peripheral surface of the strength retaining structure 132 is also equivalent to the outer peripheral surface of the tetrahedron formed by the four strength retaining arms 1321, and the tetrahedron is constructed to be approximately a cube.

[0103] In some embodiments, along the first direction, from front to back, the ratio of the orthographic cross-sectional area of ​​the outer circumference of the strength retention structure 132 in the first direction to the orthographic cross-sectional area of ​​the outer circumference of the plug-in portion 120 in the first direction is between 1 and 1.5.

[0104] Specifically, the orthographic cross-sectional area of ​​the outer circumferential surface of the strength maintaining structure 132 in the first direction may be set to be the same as the orthographic cross-sectional area of ​​the outer circumferential surface of the plug-in portion 120 in the first direction.

[0105] When the reinforcing portion 130 and the plug-in portion 120 are made of the same material, simulation analysis of the connecting terminal 100 shows that the bending strength is increased by 29.1%, which can bring great improvement to miniaturized terminals.

[0106] In some embodiments, reference Figure 3 , along the first direction, the ratio of the sum of the lengths of the strength transition arm 1311 and the strength retention arm 1321 to the length of the plug-in portion 120 is between 0.01 and 0.5.

[0107] Specifically, the ratio of the sum of the lengths of the strength transition arm 1311 and the strength retention arm 1321 to the sum of the lengths of the plug section 121 and the guide section 122 of the plug portion 120 can be set between 0.01 and 0.5.

[0108] More specifically, the ratio of the sum of the lengths of the strength transition arm 1311 and the strength retention arm 1321 to the sum of the lengths of the plug section 121 and the guide section 122 of the plug portion 120 may be set between 0.1 and 0.25.

[0109] The sum of the lengths of the strength transition arm 1311 and the strength maintaining arm 1321 is defined as L1, and the sum of the lengths of the plug section 121 and the guide section 122 of the plug section 120 is defined as L2. Then: L1:L2=0.01-0.5.

[0110] The enhancement effect is better when L1:L2=0.01~0.25.

[0111] In some other embodiments, reference Figures 8 to 10 The reinforcing portion 130 includes a strength matching structure 133, which is partially formed or connected to the rear end of the plug-in portion 120 and partially formed or connected to the front end of the main body portion 110, wherein along the first direction from the plug-in portion 120 toward the main body portion 110, the strength matching structure 133 at least partially overlaps with the plug-in portion 120 and the main body portion 110.

[0112] By providing the strength matching structure 133 , the strength between the main body 110 and the plug-in portion 120 can be improved by utilizing the strength matching structure 133 , thereby avoiding stress concentration.

[0113] It should be noted that when the reinforcing portion 130 includes the strength matching structure 133 , it is possible to increase the strength of the connecting terminal 100 without cooperating with the strength transition structure 131 and the strength maintaining structure 132 .

[0114] In some embodiments, reference Figure 10 In order to cooperate with the strength matching structure 133 , the connecting terminal 100 further includes a yielding portion 140 .

[0115] The relief portion 140 is formed between the main body 110 and the plug-in portion 120 , and the strength matching structure 133 includes a strength matching arm 1331 .

[0116] Part of the strength matching arm 1331 is formed on the plug-in portion 120 , and part of it is formed on the main body 110 , so that the strength matching arm 1331 is located in the space defined by the clearance portion 140 .

[0117] Specifically, part of the strength matching arm 1331 forms the plug-in section 121 of the plug-in part 120, and part of it forms the connecting arm 1141 of the connecting structure 114 of the main body 110, and the yielding portion 140 is formed between the connecting structure 114 of the main body 110 and the plug-in section 121 of the plug-in part 120.

[0118] In some embodiments, the relief portion 140 is configured as a groove structure.

[0119] Specifically, refer to Figure 10 A first opening groove can be opened at the connecting arm 1141 of the connecting structure 114 of the main body 110, and a second opening groove can be opened at the plug-in section 121 of the plug-in section 120. The first opening groove and the second opening groove together constitute the yield portion 140. Part of the strength matching arm 1331 is formed to the plug-in section 121 of the plug-in section 120, and part is formed to the connecting structure 114 of the main body 110, and the strength matching arm 1331 is extended toward the yield portion 140.

[0120] By providing the groove structure in conjunction with the strength matching arm 1331 , the strength of the connecting terminal 100 can be improved while also increasing the holding force of the connecting terminal 100 in the sheath housing 150 and the anti-deformation capability of the plug-in portion 120 .

[0121] refer to Figure 11 When the connecting terminal 100 is subjected to an outward pulling force in the cavity, the cavity blocking wall and the retaining structure 112 of the main body 110 of the connecting terminal 100 will interact with each other and transmit the force to the connecting arm 1141 above the connecting structure 114, thereby deforming the connecting arm 1141 above the connecting structure 114. The strength matching arm 1331 can effectively disperse part of the stress that causes the upper wall to deform, thereby increasing the ability of the upper wall of the connecting structure 114 to resist deformation.

[0122] In some embodiments, reference Figure 9A slit 10a is provided between the strength matching arm 1331 and the inner wall surface of the easing portion 140. By providing the slit 10a between the strength matching arm 1331 and the inner wall surface of the easing portion 140, the strength can be ensured while also facilitating molding.

[0123] In some embodiments, a gap may be provided between the upper strength transition arm 1311 and the left and right strength transition arms 1311 . The gap is provided to meet the needs of the production process.

[0124] Of course, without considering the variety, all the strength transition arms 1311 can be formed as one piece without any gaps.

[0125] Similarly, in order to enable the upper connecting arm 1141 to tilt upward smoothly, a gap may be provided between the upper strength retaining arm 1321 and the left and right strength retaining arms 1321 so that the connecting arm 1141 can tilt upward smoothly.

[0126] In some embodiments, the reinforcement portion 130 is integrally formed with the body portion 110 and the plug portion 120 .

[0127] refer to Figure 12 By setting the reinforcement part, it can be concluded that the stress of the connecting terminal of the present application will not be too concentrated and the strength is high.

[0128] According to a second aspect of the present application, an electronic device is provided, comprising a connection terminal 100 , which is the connection terminal 100 as described above. The electronic device has all the beneficial effects of the above connection terminal 100 , which will not be described in detail in this application.

The vehicle 10 has all the beneficial effects of the above electronic device, which will not be described in detail in this application.
