[0036] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0037] The present application embodiment provides an electrical connector 100, such as Figures 1 to 4 As shown, the electrical connector 100 includes a flange 1, a conductive member 2 and a first bonding member 3. The flange 1 is used to be installed on the device housing, which is usually provided with an opening, and the flange 1 is installed at the opening to close the opening; the conductive member 2 is passed through the flange 1, and the electronic components inside the device housing can be electrically connected to the external electronic components through the conductive member 2; the first bonding member 3 is used to bond the conductive member 2 to the flange 1.

[0038] For the above flange 1, if Figure 4 and Figure 5 As shown, the flange 1 is in the shape of a flat plate, and includes a first surface 11 and a second surface 12 disposed opposite to each other. The flange 1 is provided with a first plug hole 13, and the first plug hole 13 runs from the first surface 11 to the second surface 12. The flange 1 is provided with a plurality of first plug holes 13, and the plurality of first plug holes 13 are arranged at intervals on the flange 1. It can be understood that the flange 1 is made of an insulating material, such as a plastic material.

[0039] For the above-mentioned conductive member 2, if Figure 2 , Figure 6 and Figure 7 As shown, the conductive member 2 includes a first conductive body 21, and the first conductive body 21 is inserted into the first plug hole 13. The number of conductive members 2 can be multiple, and the first conductive body 21 of one conductive member 2 is inserted into one first plug hole 13. The first plug hole 13 is adapted to the shape and size of the first conductive body 21. In the embodiment of the present application, the first conductive body 21 is in the shape of a sheet, and the first plug hole 13 is in the shape of a long strip. It can be understood that the first conductive body 21 is a conductive material, such as a metal material, which can be copper or aluminum.

[0040] As for the first adhesive member 3, the first adhesive member 3 seals the gap between the flange 1 and the first conductor 21. The first adhesive member 3 may be adhesive or plastic. By applying the adhesive or melted plastic to the gap between the flange 1 and the first conductor 21, the gap between the flange 1 and the first conductor 21 can be sealed, thereby enhancing the sealing performance of the electrical connector 100. The number of the first adhesive members 3 may be multiple, and one first adhesive member 3 is used to seal the gap between one first plug hole 13 and one first conductor 21; the number of the first adhesive member 3 may also be one, and the gaps between multiple first plug holes 13 on the flange 1 and multiple first conductors 21 are sealed by one first adhesive member 3.

[0041] It is understandable that the flange 1 is usually made of plastic, the first conductor 21 is usually made of metal, the first adhesive 3 is usually made of adhesive or plastic, and the bonding effect between the first adhesive 3 and the flange 1 is better than the bonding effect between the first adhesive 3 and the first conductor 21. Therefore, the bonding effect between the first adhesive 3 and the first conductor 21 seriously affects the sealing effect of the electrical connector 100. To improve this problem, in the embodiment of the present application, Figure 6 and Figure 7 As shown, the first conductor 21 is provided with a first groove 211 , and the first adhesive member 3 at least partially wraps the first groove 211 , which can enhance the bonding effect between the first adhesive member 3 and the first conductor 21 , thereby enhancing the sealing effect between the first adhesive member 3 and the first conductor 21 .

[0042] For the first groove 211, Figure 6 and Figure 7 The cross section of the first groove 211 may be rectangular. A plurality of first grooves 211 may be provided, and along the opening direction of the first insertion hole 13, the plurality of first grooves 211 are arranged at intervals; along the axial direction surrounding the first insertion hole 13, the plurality of first grooves 211 are arranged around the first conductor 21, thereby further enhancing the sealing effect between the first adhesive member 3 and the first conductor 21.

[0043] In some embodiments, Figure 6 and Figure 7 As shown, the conductive member 2 further includes a second conductive body 22, the second conductive body 22 is electrically connected to the first conductive body 21, and the second conductive body 22 is used to connect an external cable. Figure 7 As shown, the second conductor 22 may be provided with a first connection hole 221, and the first connection hole 221 is used to connect an external cable. The first connection hole 221 may be a screw hole, and the external cable may be connected to the second conductor 22 by a screw. The second conductor 22 and the first conductor 21 may be welded or threaded, or the two may be integrally processed. For example, Figure 6 and Figure 7 As shown, the second conductor 22 is columnar, with a first connection hole 221 at one end, and one end of the second conductor 22 with the first connection hole 221 is connected to the first conductor 21, and a through hole is formed on the first conductor 21 to expose the first connection hole 221. Optionally, the second conductor 22 is a nut column.

[0044] Since the second conductor 22 is used to connect external cables, the second conductor 22 is at least partially located outside the flange 1. In the embodiment of the present application, Figure 2As shown, the second conductor 22 is at least partially located on the first surface 11 of the flange 1, and the second conductor 22 is used to connect the cable on the first surface 11 side of the flange 1. It can be understood that the second conductor 22 is a conductive material, such as a metal material, such as copper or aluminum.

[0045] In some embodiments, Figure 2 and Figure 4 As shown, the first surface 11 of the flange 1 is provided with a first receiving groove 14, and the second conductor 22 is electrically connected to the first conductor 21 in the first receiving groove 14. The number of first receiving grooves 14 can be multiple, and one first receiving groove 14 corresponds to one conductive member 2. The part where the first conductor 21 is connected to the second conductor 22 is a connecting part. By making the connecting part located in the first receiving groove 14, it is beneficial to protect the connecting part and improve the problem of easy breakage of the connecting part; at the same time, the first connecting hole 221 can also be provided in the first receiving groove 14, so that when multiple external cables are respectively connected to multiple second conductors 22, each first receiving groove 14 can separate each external cable, which is beneficial to reduce the risk of short circuit.

[0046] Furthermore, if Figure 2 and Figure 4 As shown, the first receiving groove 14 is adapted to the connecting portion. When the connecting portion is placed in the first receiving groove 14, the connecting portion can be clamped in the first receiving groove 14 to fix the connecting portion, reduce the shaking of the connecting portion, and reduce the risk of the connecting portion breaking. In the embodiment of the present application, the first receiving groove 14 is adapted to the first conductor 21, and clamps one end of the first conductor 21 connected to the second conductor 22. The connecting portion can also be adhered to the inner wall of the first receiving groove 14 by adhesive. Optionally, the first receiving groove 14 is rectangular.

[0047] To further fix the second conductor 22, in some embodiments, as Figure 2 and Figure 4 As shown, the flange 1 is further provided with a second insertion hole 15 penetrating from the first surface 11 to the second surface 12 , and the second conductor 22 is inserted into the second insertion hole 15 , thereby increasing the stability of the second conductor 22 installed on the flange 1 .

[0048] It can be understood that there is also a gap between the second jack 15 and the second conductor 22. To seal the gap, the electrical connector 100 further includes a second adhesive 4, which seals the gap between the flange 1 and the second conductor 22. The second adhesive 4 can be adhesive or plastic. By applying the adhesive or melted plastic to the gap between the flange 1 and the second conductor 22, the gap between the flange 1 and the second conductor 22 can be sealed, thereby enhancing the sealing performance of the electrical connector 100. The number of second adhesives 4 can be multiple, and one second adhesive 4 is used to seal the gap between one second jack 15 and one second conductor 22; the number of second adhesives 4 can also be one, and the gaps between multiple second jacks 15 on the flange 1 and multiple second conductors 22 are sealed by one first adhesive 3. Optionally, the second adhesive 4 is made of the same material as the first adhesive 3.

[0049] Since the second conductor 22 is usually made of metal, the bonding effect between the second bonding member 4 and the second conductor 22 will also seriously affect the sealing effect of the electrical connector 100. To improve this problem, in the embodiment of the present application, Figure 6 and Figure 7 As shown, the second conductor 22 is provided with a second groove 222 , and the second adhesive member 4 at least partially wraps the second groove 222 , which can enhance the bonding effect between the second adhesive member 4 and the second conductor 22 , thereby enhancing the sealing effect between the second adhesive member 4 and the second conductor 22 .

[0050] For the second groove 222, Figure 6 and Figure 7 The cross section of the second groove 222 may be rectangular. A plurality of second grooves 222 may be provided, and the plurality of second grooves 222 are arranged at intervals along the opening direction of the second insertion hole 15, so as to further enhance the sealing effect between the second adhesive member 4 and the second conductor 22. In the embodiment of the present application, the second conductor 22 is columnar, and the second groove 222 may surround the second conductor 22 around the axis of the second conductor 22.

[0051] In some embodiments, Figure 3As shown, the second conductor 22 includes multiple models, and each model of the second conductor 22 is used to connect to an external cable of one model. That is, different models of second conductors 22 are used to connect to different models of external cables. For example, the second conductor 22 includes a first model and a second model, and the size of the first model is larger than the size of the second model, or the electrical performance of the first model is better than the electrical performance of the second model. Then, the first model can connect to an external cable that passes a large current, and the second model can only connect to an external cable that passes a small current. It is understandable that the second conductor 22 can also include models other than the first model and the second model, which will not be repeated here. Optionally, the second conductor 22 includes M5 nut columns and M6 nut columns, that is, nut columns with inner diameters of 5 mm and 6 mm.

[0052] In some embodiments, Figure 6 and Figure 7 As shown, the conductive member 2 further includes a third conductive body 23, the third conductive body 23 is electrically connected to the first conductive body 21, and the third conductive body 23 is used to connect an external cable. Figure 6 As shown, the third conductor 23 may be provided with a second connection hole 231, and the second connection hole 231 is used to connect an external cable. The second connection hole 231 may be a screw hole, and the external cable may be connected to the third conductor 23 by a screw. The third conductor 23 and the first conductor 21 may be welded or threaded, or the two may be integrally processed. Figure 6 and Figure 7 As shown, the third conductor 23 is columnar, and a second connection hole 231 is formed in the axial direction, and one end of the third conductor 23 is connected to the first conductor 21, and a through hole is formed on the first conductor 21 to expose the second connection hole 231. Optionally, the third conductor 23 is an M4 nut, that is, a nut with an inner diameter of 4 mm.

[0053] It should be noted that in the embodiments of the present application, Figure 1 As shown, the third conductor 23 is located on one side of the second surface 12 of the flange 1, and the second conductor 22 and the third conductor 23 are respectively used to connect external cables on both sides of the flange 1, that is, to respectively connect cables inside the device housing and cables outside the device housing.

[0054] To fix the third conductor 23, in some embodiments, as Figure 5 As shown, the second surface 12 is provided with a mounting plate 16, and the mounting plate 16 is provided with a first through hole 161. The third conductor 23 is at least partially disposed in the first through hole 161, and the third conductor 23 can be fixed to the mounting plate 16. The first through hole 161 is adapted to the third conductor 23, for example, the first through hole 161 is circular, and the inner diameter is equal to the outer diameter of the third conductor 23, and the third conductor 23 can be embedded in the first through hole 161. Figure 5 As shown, there is one mounting plate 16 , and a plurality of first through holes 161 are spaced apart on one mounting plate 16 . In some other embodiments, there may be multiple mounting plates 16 , and one mounting plate 16 may have one or more first through holes 161 .

[0055] In some embodiments, Figure 1 and Figure 5 As shown, the second surface 12 of the flange 1 is provided with a second receiving groove 17, and one end of the first conductor 21 is clamped in the second receiving groove 17. The second receiving groove 17 is adapted to the first conductor 21. When the first conductor 21 is placed in the second receiving groove 17, the first conductor 21 can be clamped in the second receiving groove 17 to fix the first conductor 21 and reduce the shaking of the first conductor 21. The number of the second receiving grooves 17 can be multiple, and one second receiving groove 17 corresponds to the second conductor 22 of one conductive member 2. Optionally, the second receiving groove 17 is rectangular.

[0056] In some embodiments, Figures 1 to 4 As shown, the flange 1 is also provided with a second through hole 18; the electrical connector 100 further includes a screw connection 5, which is disposed in the second through hole 18. By disposing the screw connection 5 in the flange 1, it is convenient to fix the flange 1 to the device housing by screws or bolts. It can be understood that the flange 1 is provided with a plurality of second through holes 18, and the plurality of second through holes 18 are arranged at intervals along the edge of the first surface 11. Optionally, the second through hole 18 passes through from the first surface 11 to the second surface 12. Optionally, the screw connection 5 is a nut.

When the flange 1 is installed at the opening of the device housing, the sealing ring 6 contacts the edge of the opening to seal the gap between the flange 1 and the device housing, thereby enhancing the sealing effect of the flange 1 on the opening of the device housing. Optionally, the third groove 19 is adjacent to the edge of the second surface 12 and extends along the edge of the second surface 12.

[0058] The electrical connector 100 of the embodiment of the present application can enhance the sealing effect between the first adhesive member 3 and the first conductor 21 by providing the first groove 211 on the first conductor 21, and the first adhesive member 3 at least partially covers the first groove 211, thereby enhancing the sealing effect between the first adhesive member 3 and the first conductor 21, and further enhancing the sealing effect between the conductor 2 and the flange 1. The second conductor 22 and the third conductor 23 are both connected to the first conductor 21, the second conductor 22 is provided with a first connection hole 221, and the third conductor 23 is provided with a second connection hole 231, so as to facilitate the connection of the first conductor 21 with external cables on both sides of the flange 1. The second conductor 22 is inserted into the second insertion hole 15, and the third conductor 23 is embedded in the first through hole 161, so that the second conductor 22 and the third conductor 23 can be fixed, and the two ends of the first conductor 21 can be fixed at the same time.
