[0030] Currently, most Bluetooth headset charging boxes on the market use conventional spring needles without rubber rings, which cannot prevent sweat from seeping into the inner wall of the needle tube. Sweat crystals are easily accumulated at the tube mouth or inside the tube, causing the spring needle to get stuck or not rebound.

[0031] To this end, the utility model provides a charging connector.

[0032] In the embodiment of the present utility model, please refer to Figure 1 and Figure 2 The charging connector includes a needle tube 10, a spring 20 and a needle 30. The needle tube 10 is provided with a movable groove 10a and an opening 10b connected to the movable groove 10a, and the opening 10b is located at one end of the needle tube 10; the spring 20 is installed in the movable groove 10a; one end of the needle 30 is movably inserted into the movable groove 10a, and the other end of the needle 30 extends from the opening 10b; one end of the needle 30 located in the movable groove 10a is elastically abutted against the spring 20; one end of the needle 30 extending from the opening 10b is provided with a waterproof member 40.

[0033] In this embodiment, the needle 30 extends from the opening 10b of the needle tube 10 to the outside of the active groove 10a of the needle tube 10, and a waterproof component 40 is provided at the position where the needle 30 is exposed on the outer wall of the active groove 10a. The waterproof component 40 is used to seal the hole wall of the mounting hole of the box body of the Bluetooth headset charging box, so that the waterproof component 40 can seal the gap between the hole wall of the mounting hole and the outer wall of the needle 30, thereby preventing sweat from accumulating in the gap between the hole wall of the mounting hole and the outer wall of the needle 30, and preventing sweat from crystallizing here, so that the needle 30 can move smoothly in the mounting hole, thereby improving the airtightness of the charging connector, thereby ensuring the normal use of the Bluetooth headset charging box.

[0034] In one embodiment, see Figure 1 and Figure 2 The outer wall of the position where the needle 30 extends out of the opening 10b is provided with a mounting groove 30a, and the mounting groove 30a is arranged around the periphery of the needle 30, and the waterproof member 40 is installed at the mounting groove 30a.

[0035] Specifically, the outer wall of the position where the needle 30 extends out of the opening 10b is recessed to form the installation groove 30a. By setting the installation groove 30a, the groove wall of the installation groove 30a is used to limit the position of the waterproof component 40 on the needle 30, so that the waterproof component 40 is not easy to move after abutting against the hole wall of the installation hole, thereby improving the stability of the waterproof component 40 on the charging connector.

[0036] In one embodiment, see Figure 1 and Figure 2 The waterproof member 40 is a waterproof ring. By designing the waterproof member 40 as a waterproof ring, the waterproof ring is arranged around the outer wall of the position where the needle 30 extends out of the opening 10b, so that the waterproof member 40 can be sealed from various positions of the needle 30, further improving the waterproof performance of the waterproof member 40.

[0037] Optionally, the longitudinal cross-section of the waterproof member 40 is circular, elliptical, trapezoidal or rectangular.

[0038] In one embodiment, see Figure 1 and Figure 2 The waterproof member 40 is an elastic waterproof ring. The waterproof member 40 is made of elastic material, so that the waterproof member 40 has elasticity. The elastic waterproof member 40 elastically abuts against the outer wall of the needle 30 and the hole wall of the mounting hole, so that the waterproof member 40 more tightly seals the gap between the outer wall of the needle 30 and the hole wall of the mounting hole, thereby improving the waterproof performance of the charging connector.

[0039] In one embodiment, see Figure 1 and Figure 2 , the outer diameter of the waterproof member 40 is greater than the outer diameter of the needle 30.

[0040] Specifically, the outer diameter of the waterproof component 40 is larger than the outer diameter of the needle 30, and the depth of the mounting groove 30a is smaller than the outer diameter of the waterproof component 40, so that the waterproof component 40 can protrude out of the mounting groove 30a, and the protruding waterproof component 40 abuts more tightly against the mounting hole of the Bluetooth headset charging box, thereby improving the sealing of the waterproof component 40 between the mounting hole and the outer wall of the needle 30.

[0041] In one embodiment, see Figure 1 and Figure 2 The needle 30 includes an embedded portion 31, an external portion 32 and an intermediate portion 33 connected between the embedded portion 31 and the external portion 32. A mounting groove 30a is provided at the connection between the intermediate portion 33 and the external portion 32, and the diameter of the embedded portion 31 is greater than the diameter of the opening 10b.

[0042] Specifically, the needle 30 is divided into an embedded portion 31, an external portion 32 and a middle portion 33, and the diameter of the embedded portion 31 is designed to be larger than the diameter of the opening 10b, so that the embedded portion 31 cannot be detached from the movable groove 10a of the needle tube 10, and the embedded portion 31 is used to fix the needle 30 on the needle tube 10, while the external portion 32 is used to contact and conduct with the charging part of the Bluetooth headset, and the middle portion 33 is used to connect the embedded portion 31 and the external portion 32; by setting a mounting groove 30a between the external portion 32 and the middle portion 33, when the needle 30 moves to a position close to the position between the external portion 32 and the middle portion 33, the waterproof component 40 can seal the opening 10b of the needle tube 10, thereby further increasing the moving range of the needle 30.

[0043] In one embodiment, see Figure 1 and Figure 2The external part 32 is hemispherical or mushroom-shaped. In this way, the external part 32 has a rounded contour, which can make contact with the charging part of the Bluetooth headset without scratching the charging part of the Bluetooth headset, thereby protecting the Bluetooth headset that needs to be charged.

[0044] In one embodiment, see Figure 1 and Figure 2 The outer wall of the middle part 33 is provided with a retaining rib, which is arranged around the outer wall of the middle part 33 and is spaced apart from the mounting groove 30a; the diameter of the retaining rib is larger than the diameter of the opening 10b, and is used to block sweat.

[0045] Specifically, the retaining rib is arranged adjacent to the mounting groove 30a, and the retaining rib and the middle portion 33 are an integrally formed structure, so that the retaining rib is not easily broken from the middle portion 33; by arranging the retaining rib at a position adjacent to the mounting groove 30a, the retaining rib can also be used to further prevent sweat from entering the movable groove 10a of the needle tube 10, thereby improving the air tightness of the charging connector.

[0046] In one embodiment, see Figure 1 and Figure 2 The outer wall of the needle tube 10 is provided with a limiting protrusion 10c, which is arranged around the outer peripheral wall of the needle tube 10 and is used to engage with the mounting hole of the box body of the Bluetooth headset charging box. In this way, the limiting protrusion 10c is engaged with the mounting hole of the box body of the Bluetooth headset charging box, so that the charging connector and the Bluetooth headset charging box are assembled more tightly.

[0047] The utility model also proposes a Bluetooth headset charging box, which includes a box body and a charging connector. The box body is provided with a mounting cavity and a mounting hole, and the mounting hole is connected to the mounting cavity; the charging connector is installed at the mounting hole.

[0048] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
