[0036] Reference below Figure 1-Figure 3 A dust cover 100 of a power swap connector according to an embodiment of the present utility model is described.

[0037] like Figure 2 and Figure 3 As shown, according to the dust cover 100 of the power exchange connector according to an embodiment of the utility model, the dust cover 100 includes a cover body 1 and a wire sleeve 2.

[0038] The two opposite sides of the cover body 1 are the inner side and the outer side. The cover body 1 can cover one end of the power exchange connector 200, and can prevent dust, impurities, etc. from entering the inner side of the cover body 1 from the outer side of the cover body 1, thereby preventing dust and impurities from contaminating one end of the power exchange connector 200. The cover body 1 is provided with a perforation 11 and a wire hole 12, and the perforation 11 and the wire hole 12 can pass through an electrical connector connected to the power exchange connector 200, and the electrical connector can be a wiring harness 4, a terminal assembly, etc.

[0039] The wire sleeve 2 is arranged on the outside of the cover body 1. The wire sleeve 2 can be sleeved on the wire harness 4. The wire sleeve 2 can prevent dust from entering the inside of the cover body 1. One end of the wire sleeve 2 is connected to the cover body 1. Specifically, one end of the wire sleeve 2 is connected to the edge of the wire hole 12.

[0040] In the related art, the gap between the wire harness through hole of the power exchange connector and the wire harness is large, and dust can enter the inside of the power exchange connector 200 through the gap, reducing the service life. In this application, the wire sleeve 2 of the dust cover 100 can be set on the wire harness 4, and the cover body 1 is connected through one end of the wire sleeve 2. Specifically, one end of the wire sleeve 2 is located on the edge of the wire through hole 12, so as to prevent dust, impurities and other substances from passing through the gap 5 between the wire through hole 12 and the wire harness 4, thereby improving the dustproof effect.

[0041] According to the dust cover 100 of the power exchange connector in the embodiment of the utility model, the cover body 1 can cover one end of the power exchange connector 200, which can prevent dust, impurities and the like from entering the inside of the cover body 1 from the outside of the cover body 1, thereby preventing dust and impurities from contaminating one end of the power exchange connector 200; one end of the wire sleeve 2 is located on the edge of the wire hole 12, thereby preventing dust, impurities and the like from passing through the gap 5 between the wire hole 12 and the wiring harness 4, thereby improving the dustproof effect, and thereby improving the service life of the power exchange connector 200.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, the wire sleeve 2 includes a tapered section 21. In the direction away from the cover body 1, the diameter of the tapered section 21 gradually decreases, so that the wire sleeve 2 forms a bell-mouth structure, and the tail of the bell-mouth structure is effectively wrapped with the wire harness 4, reducing the gap 5 between the wire sleeve 2 and the wire harness 4, thereby achieving an effective dustproof effect; on the other hand, the tapered section 21 occupies a small volume, which can reduce the volume of the wire sleeve 2, making the structure of the dust cover 100 more compact.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments, the tapered section 21 is located at one end of the connecting cover body 1 of the wire sleeve 2, and the shape of the pipe mouth of the tapered section 21 is consistent with the shape of the wire hole 12, so that the shape of the tapered section 21 is more matched with the shape of the wire hole 12, thereby improving the adaptability between the wire sleeve 2 and the wire hole 12, which is beneficial to reducing the assembly gap 5 and improving the dustproof effect.

[0044] like Figure 2 and Figure 3 As shown, in some embodiments, the wire sleeve 2 includes a straight tube section 22, which is a tubular structure with a constant diameter, and the straight tube section 22 is located at one end of the wire sleeve 2 away from the cover body 1. The straight tube section 22 is provided to facilitate the assembly between the wire sleeve 2 and the wire harness 4, and can be effectively bundled with the wire harness 4, thereby improving the stability and reliability of the connection.

[0045] like Figure 2 and Figure 3 As shown, for example, in the present application, the structure of the dust cover 100 at the wire hole 12 is changed and designed, and a wire sleeve 2 with a bell-mouth structure is added. The tail of the bell-mouth structure is effectively wrapped with the wire harness 4, reducing the gap 5 between the dust cover 100 and the wire harness 4, thereby improving the dustproof effect. The tail of the tapered section 21 of the wire sleeve 2 is designed to be a closed shape, and a straight tube section 22 is also provided at the tail of the tapered section 21, so that the wire sleeve 2 can form a tightening trend after matching with the wire harness 4, and can be effectively bundled with the wire harness 4, reducing the possibility of the wire sleeve 2 falling off due to movement stress during the floating process of the power exchange connector, thereby improving product quality.

[0046] like Figure 2 and Figure 3 As shown, in some specific examples, the wire hole 12 is a square hole, and the straight pipe section 22 is a round straight pipe section, which simplifies production and processing, reduces costs, and improves production efficiency.
