[0033] Example 1

[0034] like Figures 1 to 5 As shown, this embodiment provides a thin and light quick-detachable connector structure, including a female connector 1 and a male connector 3. The first end of the female connector 1 is provided with a row of spring pins 2. The spring pins 2 are ultra-thin POGPINs. The number can be set according to the connection requirements of the actual product and is not specifically limited here. The welding pins of the spring pins 2 pass through the female connector 1 and are located at the second end of the female connector 2. The first end of the male connector 3 is provided with metal contacts 7 equal to the number of spring pins 2. The positions of the metal contacts 7 correspond one-to-one to the positions of the spring pins 2 and are also arranged in a row. After the male connector 1 and the female connector 3 are connected, the spring pins 2 and the metal contacts 7 of the male connector abut against each other to achieve electrical connection and conduction. In this embodiment, a wire groove 8 is provided in the male connector 3, and a wire outlet hole 6 is provided at the second end of the male connector 3. The wire groove 8 connects the welding pins of the metal contacts 7 with the wire outlet hole 6. That is, each welding pin of the metal contact 7 is fixedly electrically connected to the first end of a connecting wire. The connecting wire is placed in the wire groove 8, and the second end of the connecting wire passes through the wire outlet hole 6 for electrical connection to other devices.

[0035] In this embodiment, a locking shell 11 is fixedly connected to the female connector 1. The locking shell 11 has openings at both ends. The first end of the locking shell 11 is fixedly sleeved on the female connector 1. Of course, the female connector 1 and the locking shell 11 can also be made by integral molding. The second end of the locking shell 11 is open away from the spring pin 2. The male connector 3 is clamped into the second end of the locking shell 11, and the metal contact 7 is brought into contact with the spring pin 2 for conduction. The male head 3 and the locking shell 11 can achieve a stable connection through interference fit. In this embodiment, in order to further provide the stability of the connection, a locking spring piece 12 is provided on the locking shell 11, and a locking groove 4 corresponding to the position of the locking spring piece 12 is provided on one side of the male head 3. When the male head 3 is clamped to the locking shell 11, the locking spring piece 12 will be pushed up first. After the male head 3 is clamped into place, the locking spring piece 12 just coincides with the locking groove 4, and the locking spring piece 12 is clamped into the locking groove 4, thereby locking the male head 1 in the locking shell 11 to achieve a very stable connection. When removing the male head 3, a tool is required to pry up the locking spring piece 12 before it can be pulled out. It is suitable for clamping for a long time, or scenarios where the firmness of the clamping connection is very high, such as connecting headphone products through the quick-release connector on a headband product. The locking structure can provide a relatively stable bearing capacity. In order to facilitate the insertion of the male connector 3 into the locking shell 11 , chamfers 10 are provided on both sides of the male connector 11 near the metal contact 7 . The chamfers 10 serve as guide angles to facilitate quick alignment of the male connector 3 and the locking shell 11 .

[0036] Furthermore, a positioning groove 9 is provided in the male connector 3, and a positioning block 16 is clamped in the positioning groove 9. A mounting hole 5 is also provided at the second end of the male connector 3. The positioning block 16 is fixedly connected to a mounting wire 17. The end of the mounting wire 17 away from the positioning block 16 passes through the housing of the male connector 3 from the mounting hole 5. The mounting wire 17 can be used to assist in carrying the weight of some loads, such as mounted headphones, etc.

[0037] Example 2

[0038] like Figure 6-9As shown, the embodiment provides another light and thin quick release connector structure, which has the same main structure as that of the embodiment 1, and the main difference is that the connection is not fixed by the locking shell 11, but by the magnetic attraction structure. Specifically, the side of the female head 1 is fixedly connected with the side suction plate 21, and the side suction plate 21 and the female head 1 form an open clamping cavity. The first magnet 18 is arranged on the surface of the side suction plate 21, and the second magnet 19 is arranged on the outer side of the male head 3. The magnetic properties of the first magnet 18 and the second magnet 19 are opposite. The male head 3 is connected to the clamping cavity of the female head 1, and the first magnet 18 and the second magnet 19 are fixed by magnetic attraction, so as to realize the conduction of the spring needle 2 and the metal contact 7. Further, the center of the magnetic poles of the first magnet 18 and the second magnet 19 is offset, for example, the width of the second magnet 19 is greater than that of the first magnet 18, so that the center of the magnetic poles of the first magnet 18 and the second magnet 19 has an offset distance, so that the male head 3 is always subjected to a pressing force in the direction of the spring needle 2 of the female head 1, further ensuring the stable connection and conduction of the spring needle 2 and the metal contact 7.

[0039] In other embodiments, a locking shell 11 as in the embodiment 1 can also be fixedly connected to the female head 1 at the same time. In this case, the side suction plate 21 is located on one side of the locking shell 11, but the locking spring sheet 12 is not required. The male head 3 and the female head 1 are fixed by magnetic attraction of the first magnet 18 and the second magnet 19. In this case, the locking shell 11 mainly provides the function of stabilizing the male head 3, which can effectively prevent the male head 3 from shaking left and right.

[0040] In the embodiment, the metal contact 7 can be electrically connected to other devices by the wire slot 8 and the connecting wire as in the embodiment 1, and can also be connected by a circuit board. Specifically, a flexible circuit board 13 is arranged in the male head 3. The first end of the flexible circuit board 13 is provided with a contact pad 14 corresponding to the welding pin of the metal contact 7. The second end of the flexible circuit board 13 close to the wire outlet hole 6 is provided with a wire pad 15. The contact pad 14 and the wire pad 15 are electrically connected one by one through the flexible circuit board 13. The metal contact 7 is fixedly and electrically connected to the contact pad 14 corresponding to the metal contact 7. The wire pad 15 is respectively welded with a connecting wire. The connecting wire is arranged to pass through the wire outlet hole 6 and is used to be electrically connected to other devices. The metal contact 7 is connected by the flexible circuit board 13, which can further simplify the internal structure of the male head 3, and facilitate the design of the male head 1 in a lighter and thinner direction.

[0041] Embodiment 3

[0042] As Figures 10-11As shown, the embodiment provides another kind of magnetic fixing thin and light quick release connector structure, the main structure is same with the embodiment, the main difference is that the locking shell 11 does not need locking spring 12, the third magnet 20 is fixedly connected in the male head 3, the locking shell 11 is made of magnetic material, such as stainless steel metal and other metal materials, after the male head 3 is inserted into the locking shell 11, the third magnet 20 generates magnetic attraction to the locking shell 11 made of magnetic material, thereby realizing the fixation of the male head 3.

[0043] The above is the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, under the premise of can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
