[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0041] Please refer to Figure 1 and Figure 4The sealing member 100 and the electrical connector 1000 provided in the embodiment of the present invention can solve the above-mentioned problems, which will be described in detail below.

[0042] refer to Figure 1-Figure 4 , the sealing member 100 comprises a first sealing portion 110 and a second sealing portion 120 formed in one piece;

[0043] The first sealing portion 110 is used to be disposed between the upper cover 200 and the lower cover 300 of the electrical connector 1000 , and the second sealing portion 120 is disposed at the wire outlet 500 of the electrical connector 1000 .

[0044] When in use, the seal 100 can seal the position between the upper cover 200 and the lower cover 300 and the position of the wire outlet 500 through the first sealing part 110 and the second sealing part 120 respectively. The two sealing parts are integrally formed to avoid missing assembly during assembly, and there will be no gap between the two sealing parts, thereby ensuring a waterproof effect.

[0045] It is worth noting that by integrally molding the two sealing parts, the seal 100 can seal multiple positions at the same time during installation. Compared with the prior art, the number of seals 100 during assembly is reduced, which not only avoids missing installation, but also simplifies the molding process of the seal 100, thereby reducing manufacturing costs.

[0046] refer to Figure 1 In order to improve the connection strength between the first sealing part 110 and the second sealing part 120 and prevent the connection between the two from being easily broken due to insufficient strength, the first sealing part 110 can be provided with a reinforcement block 111, and the reinforcement block 111 is connected to the second sealing part 120.

[0047] In this embodiment, the cross-section of the first sealing portion 110 is rectangular. By limiting the cross-sectional shape of the first sealing portion 110, the first sealing portion 110 is easier to position during production and installation, thereby improving ease of use. The cross-section of the second sealing portion 120 is circular, so that it is convenient to be mounted on the connecting line 400 located at the discharge hole, ensuring that the second sealing portion 120 can be tightly pressed against the connecting line 400, thereby ensuring the sealing strength at the discharge port.

[0048] Of course, in other embodiments of the present invention, the cross-sectional shape of the first sealing portion 110 may also be other shapes such as circular, trapezoidal, and fan-shaped, and the cross-sectional shape of the second sealing portion 120 may also be other shapes such as rectangular, trapezoidal, and fan-shaped. There is no limitation on the specific cross-sectional shapes of the first sealing portion 110 and the second sealing portion 120.

[0049] In order to ensure a certain degree of flexibility during the sealing process and facilitate extrusion to avoid gaps, the first sealing part 110 and the second sealing part 120 can be made of elastic materials, and the elastic compression of the two can be set to 10% to 45%, so as to avoid gaps caused by excessive elastic compression and affect assembly due to insufficient elastic compression.

[0050] Specifically, the elastic compression amount of the first sealing portion 110 and the second sealing portion 120 may be 10%, 15%, 20%, 25%, 30%, 35%, 40% and 45%, etc., and there is no limitation on the specific elastic compression amount of the two.

[0051] refer to Figure 2-Figure 4 The embodiment of the utility model further provides an electrical connector 1000, comprising:

[0052] An upper cover 200, a lower cover 300, a connecting line 400 and a sealing member 100;

[0053] The same end of the upper cover 200 and the lower cover 300 forms a wire outlet 500, the connecting wire 400 is accommodated in the wire outlet 500, the first sealing portion 110 is arranged between the upper cover 200 and the lower cover 300, and the second sealing portion 120 is arranged at the wire outlet 500 and sleeved on the connecting wire 400. The electrical connector 1000 includes a sealing member 100, which has all the functions of the sealing member 100.

[0054] In this embodiment, the outlet 500 is a circular structure, and a semicircular opening is respectively opened at the same end of the upper cover 200 and the lower cover 300, and the two semicircular openings are enclosed together to form the outlet 500. The cross section of the connecting wire 400 is also circular, and the connecting wire 400 extends from the outer side of the upper cover 200 and the lower cover 300, so that its end is accommodated in the outlet 500 and connected to the electrical components between the upper cover 200 and the lower cover 300.

[0055] Therefore, the corresponding second sealing portion 120 is also in a circular ring shape, which is convenient for being sleeved on the connecting wire 400 to seal the gap between the connecting wire 400 and the wire outlet 500 .

[0056] Of course, in other embodiments of the present invention, the wire outlet 500 may also be a rectangular, triangular, or fan-shaped structure, the corresponding cross-section of the connecting wire 400 may also be a rectangular, triangular, or fan-shaped structure, and the second sealing portion 120 may also be a rectangular, triangular, or fan-shaped structure formed by enclosing.

[0057] Furthermore, a limiting groove 410 may be provided on the outer side of the connecting wire 400 for accommodating the second sealing portion 120 to prevent the second sealing portion 120 from being axially displaced after being sleeved on the connecting wire 400 .

[0058] refer to Figure 5 and Figure 6 In order to ensure that the seal 100 is positioned and pressed and to prevent a gap from appearing on both sides of the seal 100, one of the upper cover 200 and the lower cover 300 may be provided with a groove 310, and the other may be provided with a boss 210, the first sealing portion 110 is accommodated in the groove 310, and the boss 210 is used to resist the first sealing portion 110.

[0059] In this embodiment, the groove 310 is arranged on the lower cover 300, and the boss 210 is arranged on the upper cover 200. During assembly, the first sealing part 110 can be placed in the groove 310, and then the upper cover 200 and the lower cover 300 are closed to facilitate the boss 210 to press against the first sealing part 110.

[0060] Of course, in other embodiments of the present invention, the groove 310 may be disposed on the upper cover 200 , and the boss 210 may be disposed on the lower cover 300 .

[0061] refer to Figure 5 and Figure 6 A first mounting portion 220 and a second mounting portion 320 are respectively formed on the edges of the upper cover 200 and the lower cover 300, and a first avoidance portion 211 and a second avoidance portion 311 are respectively formed on the boss 210 and the groove 310. The first avoidance portion 211 is located on the inner side of the first mounting portion 220, and the second avoidance portion 311 is located on the inner side of the second mounting portion 320.

[0062] Specifically, the first mounting portion 220 and the second mounting portion 320 are used to cooperate with each other to enable the upper cover 200 and the lower cover 300 to be detachably connected, which may be a snap-fit ​​structure or a threaded connection structure, and the specific structure is not limited.

[0063] In this embodiment, the upper cover 200 and the lower cover 300 are both rectangular hollow structures, the first mounting portion 220 and the second mounting portion 320 are respectively arranged on the four sides of the rectangular parallelepiped, the boss 210 and the groove 310 are arranged along the edge of the rectangular parallelepiped, and when extending to a position close to the first mounting portion 220 and the second mounting portion 320, they detour from the inner side of the first mounting portion 220 and the second mounting portion 320, thereby forming a first avoidance portion 211 and a second avoidance portion 311.

[0064] It should be noted that when the upper cover 200 and the lower cover 300 are both triangular, circular or fan-shaped structures, the first mounting portion 220 and the second mounting portion 320 are also respectively arranged at the edge of the structure, and the boss 210 and the groove 310 can also extend along the edge of the structure. When the boss 210 and the groove 310 are close to the position of the first mounting portion 220 and the second mounting portion 320, they should also be detoured from the inner side of the first mounting portion 220 and the second mounting portion 320 to form the first avoidance portion 211 and the second avoidance portion 311. It can be understood that the first avoidance portion 211 is close to the geometric center of the upper cover 200 relative to the first mounting portion 220, and the second avoidance portion 311 is close to the geometric center of the lower cover 300 relative to the second mounting portion 320.

[0065] In order to make the boss 210 better squeeze the seal 100 in the groove 310, the height of the boss 210 can be limited to 20% to 40% of the depth of the groove 310. Specifically, the height of the boss 210 is 20%, 25%, 30%, 35% and 40% of the depth of the groove 310.

[0066] refer to Figure 5 and Figure 6 Since the first sealing part 110 is provided with a reinforcing block 111 connected to the second sealing part 120, the connection strength of the two sealing parts is improved; an extension groove 312 can be provided on the groove 310 near the outlet 500, and an extension platform 212 can be provided on the boss 210 near the outlet 500. The reinforcing block 111 is accommodated in the extension groove 312, and the extension platform 212 is used to resist the reinforcing block 111. By providing the extension groove 312 and the extension platform 212 at the corresponding position of the reinforcing block 111, the reinforcing block 111 can be accommodated and resisted at the same time, so that the reinforcing block 111 can ensure the position stability of the reinforcing block 111 while enhancing the connection strength, and can also ensure the sealing performance at the position of the reinforcing block 111.

[0067] refer to Figure 5 When the boss 210 squeezes the seal 100, in order to achieve a better extrusion and holding effect, the boss 210 can be made conical, and the width of the boss 210 gradually decreases from the bottom end (the end of the boss 210 away from the seal 100) to the top end (the end of the boss 210 that squeezes the seal 100), that is, the extrusion and holding pressure can be concentrated on the contact part between the boss 210 and the seal 100, thereby ensuring that the pressure (i.e., pressure) per unit area of ​​the holding is as high as possible to fully guarantee the sealing performance.

[0068] It is worth noting that during the assembly process, the second sealing portion 120 can be first sleeved on the connecting wire 400, and then the connecting wire 400 can be placed at the semicircular opening of the lower cover 300, and then the first sealing portion 110 can be placed in the groove 310, and then the upper cover 200 can be controlled to approach the lower cover 300. During the approaching process, the boss 210 squeezes and supports the first sealing portion 110, and at the same time, the semicircular opening of the upper cover 200 and the semicircular opening of the lower cover 300 are connected to form the outlet 500, and the second sealing portion 120 is squeezed between the outlet 500 and the connecting wire 400, thereby completing the sealing assembly operation of the electrical connector 1000.

[0069] In summary, the sealing member 100 and the electrical connector 1000 provided by the embodiments of the present invention have at least the following advantages:

[0070] (1) When in use, the seal 100 can seal the position between the upper cover 200 and the lower cover 300 and the position of the wire outlet 500 through the first sealing part 110 and the second sealing part 120 respectively. The two sealing parts are integrally formed to avoid missing during assembly, and there is no gap between the two sealing parts, thereby ensuring a waterproof effect.

[0071] (2) The first sealing portion 110 is provided with a reinforcing block 111, which is connected to the second sealing portion 120, so as to improve the connection strength between the first sealing portion 110 and the second sealing portion 120, thereby preventing the connection between the two from being easily broken due to insufficient strength.

[0072] (3) One of the upper cover 200 and the lower cover 300 is provided with a groove 310, and the other is provided with a boss 210. The first sealing portion 110 is accommodated in the groove 310, and the boss 210 is used to abut against the first sealing portion 110, which can ensure that the sealing member 100 is positioned and pressed to prevent a gap from appearing on both sides of the sealing member 100.
