[0035] As Figures 3 to 6 As shown, in an embodiment of the present utility model, a high-voltage electrical connector for improving assembly defects includes a socket 1. A flange 101 is provided on the socket 1. A plurality of connection holes 102 are provided on the flange 101. An elastic bushing 110 with a variable outer diameter is provided in the connection holes 102. A pre-assembly clearance 103 is provided at one end between the connection holes 102 and the elastic bushing 110. The pre-assembly clearance 103 is provided on the connection holes 102 or the elastic bushing 110. The diameter of the connection holes 102 at the pre-assembly clearance 103 is larger than the inner diameters of other segments, and the diameter of the elastic bushing 110 at the pre-assembly clearance 103 is smaller than the outer diameters of other segments.

[0036] During installation, one end of the elastic bushing 110 is aligned with one end of the connection hole 102 where the pre-installation gap 103 is set, and it is gently pushed in. Since the diameter of the connection hole 102 is larger at the pre-installation gap 103, it provides sufficient space for the installation of the elastic bushing 110 and allows a certain deviation during the installation process. As the elastic bushing 110 is further pushed in, the pre-installed section can correct the deviation and provide a guiding force. The elastic bushing 110 enters a section with a smaller diameter in the connection hole 102, and the outer diameter of the elastic bushing 110 shrinks, tightly fitting with the inner wall of the connection hole 102, forming a firm connection.

[0037] In this embodiment, by setting the pre-installation gap 103, the elastic bushing 110 can be more easily aligned with the connection hole 102 during installation, reducing burrs caused by alignment deviation, simplifying the installation process, improving production efficiency, and increasing the production yield. Secondly, the change in the outer diameter of the elastic bushing 110 enables it to tightly fit with the inner wall of the connection hole 102 after installation, improving the firmness of the connection and preventing loosening or falling off during use.

[0038] The elastic bushing 110 is made of an elastic material, such as a steel sheet, and has a telescopic joint 111 provided along the axial direction of the wall surface for diameter variation.

[0039] As Figure 5 shown, in a preferred example, first chamfers are provided at both ends in the connection hole 102, and second chamfers are provided at both ends of the elastic bushing 110.

[0040] In this embodiment, by setting the first chamfer and the second chamfer, and their mutual cooperation enhances the guiding property of the assembly, enabling the elastic bushing 110 to enter the connection hole 102 more accurately, reducing friction and resistance during the assembly process, further improving the smoothness and precision during the assembly process, and reducing burrs and scratches caused by direct hard contact, thereby protecting the surface quality of the connection hole 102 and the elastic bushing 110.

[0041] As Figure 1 、 Figure 2 、 Figures 6 to 11 shown, in a preferred example, the socket 1 is detachably connected to the plug 2.

The first terminal 201 is a female seat, the second terminal 104 is a male head, and the first terminal 201 and the second terminal 104 are inserted and matched.

[0042] In the prior art, in order to meet the maximum load requirement in the connector, a relatively thick wire diameter is uniformly adopted, resulting in unnecessary redundancy on the PINs carrying a smaller current. This not only increases the wire material and manufacturing costs, but also occupies valuable internal space of the connector, restricting the size of the connector. Therefore, in this embodiment, by adopting first terminals 201 and second terminals 104 of different specifications, the cost is relatively low, and the space is fully utilized, making the internal structure of the connector compact and the overall size smaller. In addition, when the first terminals 201 and second terminals 104 of different specifications are docked, the first terminals 201 and second terminals 104 with non-corresponding specifications cannot be docked, so they need to correspond one by one, thus preventing misconnection and ensuring the accuracy and safety of the electrical connection.

[0043] As Figure 1 , Figure 2 , Figures 6 to 12 shown, a first connecting sleeve 202 is provided on the plug 2, and the first terminal 201 is hidden in the first connecting sleeve 202. A second connecting sleeve 105 inserted into the first connecting sleeve 202 is provided on the socket 1, and the second terminal 104 is hidden in the second connecting sleeve 105.

[0044] The plug 2 is provided with a protective sleeve 203 sleeved outside each first terminal 201 in the first connecting sleeve 202. The protective sleeve 203 is provided with a plugging hole at the connecting end.

[0045] The socket 1 is provided with a protective baffle 106 in the second connecting sleeve 105. The protective baffle 106 encloses a plurality of slots, and the slots are in plugging fit with the protective sleeve 203. Each second terminal 104 is separately hidden in each slot.

[0046] In this embodiment, the first connecting sleeve 202 and the protective sleeve 203 on the plug 2 hide the first terminal 201, and the plugging hole enables the first terminal 201 and the second terminal 104 to be smoothly docked. At the same time, the slots enclosed by the protective baffle 106 separate each second terminal 104 to avoid mutual interference, and also ensure a tight plugging with the protective sleeve 203, preventing electrical short - circuit and electric shock risks, further enhancing the stability of the connection between the first terminal 201 and the second terminal 104, improving the safety of the device, and providing safety protection for the device and personnel.

[0049] As Figure 2 , Figure 7 , Figure 9 , Figure 11 , Figure 12 shown in, in a preferred example, an elastic buckle 205 is provided on the first connecting sleeve 202, a fixing buckle 108 that engages with the elastic buckle 205 is provided on the second connecting sleeve 105, a movable buckle 206 is slidably connected to the first connecting sleeve 202 at the elastic buckle 205, the movable buckle 206 restricts the elastic deformation of the elastic buckle 205 in the first position, and the elastic buckle 205 freely elastically deforms in the second position of the movable buckle 206.

[0050] A first seal 209 is provided in the first connecting sleeve 202 of the plug 2. The inner wall of the first seal 209 abuts against the wall surface of the plug 2, the outer wall of the first seal 209 abuts against the inner wall of the second connecting sleeve 105. A retaining ring 210 is provided near the insertion end of the plug 2 on the first seal 209. The retaining ring 210 is provided with a first buckle 211, and a first slot 207 that engages with the first buckle 211 is provided on the plug 2.

[0051] In this embodiment, by providing the mutually engaging elastic buckle 205 and the fixing buckle 108, and providing the movable buckle 206 that restricts the deformation of the elastic buckle 205, the connection between the plug 2 and the socket 1 in the connected state is more reliable, not easily falling off or loosening. When separating, only need to slide the movable buckle 206 to the second position, the elastic buckle 205 can freely deform, releasing the engagement with the fixing buckle 108. At the same time, by providing the first seal 209, the sealing performance between the plug 2 and the socket 1 is improved, effectively preventing the intrusion of external factors such as dust and moisture, and protecting the electrical safety of the connection. In addition, the engagement connection between the first buckle 211 on the retaining ring 210 and the first slot 207 on the plug 2 fixes the first seal 209, preventing the first seal 209 from falling off when the plug 2 and the socket 1 are inserted and removed, ensuring the sealing effect and ensuring the electrical connection safety.

[0052] In actual application, the movable buckle 206 can be provided on any side wall surface of the first connecting sleeve 202, facilitating adaptation to various usage requirements.

[0053] As Figure 6 , Figure 7 , Figure 9 and Figure 11As shown, in a preferred embodiment, a second seal 212 is provided at the terminal of the plug 2. A plurality of first wire holes 213 for each first terminal 201 to pass through are provided on the second seal 212. A end cap 214 is provided at the terminal of the plug 2. Second wire holes 215 corresponding to the first wire holes 213 one by one are provided on the end cap 214. A second card slot 216 is provided on the end cap 214.

[0054] The flange 101 is provided with an installation groove on the connection surface, and a third seal 112 is provided in the installation groove.

[0055] In this embodiment, through the second seal 212, dust, moisture and other pollutants at the terminal are prevented from invading, ensuring a pure environment for electrical connection. At the same time, the end cap 214 is engaged with the second buckle 208 on the plug 2 through the second card slot 216 to achieve the stable installation of the end cap 214, thereby fixing the second seal 212 and ensuring the sealing effect of the terminal.
