[28] It is worth mentioning that, in the connector of the present invention, the center of the rotary lock 22 is provided with a slot 221, and the boss 214 of the dial 21 is engaged with the slot 221, The dial 21 and the lock 22 are caused to rotate coaxially. At the same time, the center of the boss 212 is provided with a locking hole 215, and the center of the slot 221 is provided with a central through hole 22 2, and the screw 24 is inserted into the locking hole 215 from below the central through hole 222. The dial 21 and the lock 22 are locked.

Referring to FIG. 3, the front end of the connector body 1 is provided with a dial groove 16 communicating with the upper through hole 151; the upper step 211 of the dial 21 protrudes to form a handle 216, the hand A 216 is placed within the dial wheel slot 16 and is movable within the dial wheel slot 16.

As shown in FIG. 3, the connection assembly 3 includes a PCB board 31 electrically connected to the wires 4, and a contact pin 32 mounted on the PCB board 31; the connection assembly 3 protrudes from the connector body through the contact pins 32. The portion of the lower surface is electrically connected to the main body, and the surface of the stylus is provided with a layer of elastic material.

[31] The structure inside the connector body will be described below. The connector body 1 is provided with a cavity 12, and the cavity 12 is provided with a PCB fixing plate 13 fixed on the connector body 1. The stylus is placed on the PCB fixing plate 13 and the stylus The 32-position matching hole is fixed in the connector body 1 and injection molded together with the connector body; the cavity 12 is provided with a connector upper case 14 and is detachably mounted on On the connector body 1. After the stylus 32 is soldered to the PCB, it is loaded into the reserved cavity 12 of the connector body 1, mounted on the PCB fixing plate 13, and the wire is soldered on the PCB, and the C-ring 19 is used to lock the wire. 4 Injection molding with the connector. The connector upper case 14 is then placed over the cavity 12 to seal it. Although the present invention provides a specific internal mounting of the connector body 1, it should be understood that the present invention can be implemented in a variety of ways.

[32] The connector of the present invention has a plurality of positions that are mated to the corresponding positions of the housing of the main unit 5. For example, a wedge-shaped limiting post 223 is disposed on the side of the connector rotation lock 22, and is coupled with the main body wedge-shaped limiting hole 51 for connection. A tail buckle 17 is disposed under the tail of the connector body 1 to cooperate with the main wedge-shaped limiting slot 52 for connection. A middle snap 18 is disposed at a lower portion of the connector body 1 to cooperate with the host limiting hole 53 for connection.

[33] After the attachment is installed, the connector tail buckle 17 is first engaged with the main body wedge-shaped limiting slot 52, the connector rotation lock 22 is aligned with the main body wedge-shaped limiting hole 51, and the wedge-shaped limiting post on the same rotation lock 22 223 corresponds to the wedge surface of the main body wedge-shaped limiting hole 51. Press the connector in, the lock 22 is forced to enter the main wedge limit along the wedge surface. Inside the hole 51. The upper portion of the main body wedge-shaped limiting hole 51 is provided with a main body wedge-shaped limiting member 512, and the lower portion is a cavity. The main body wedge-shaped limiting member 512 includes an upper wedge surface 5121, a lateral corner surface 5122, and a bottom surface 5123. Under the action of an external force, the wedge-shaped surface 2231 of the wedge-shaped limiting post 223 on the rotary lock 22 contacts the wedge-shaped surface 5121 of the main-plate wedge-shaped limiting member 512 and slides down along the wedge-shaped surface 5121, thereby causing the rotation lock 22 and the dial 21 Rotating, thereby causing the torsion spring 23 to deform; when the two inclined faces are disengaged, the wedge-shaped limiting post 223 on the rotary lock 22 bypasses the corner surface 5122; under the force of the torsion spring 23 gradually recovering the deformation, the rotary lock 22 When the dial 21 rotates in the opposite direction to the sliding process, the wedge-shaped limiting post 223 on the rotary lock 22 enters the cavity at the bottom of the main wedge-shaped limiting hole 51 until the torsion spring 23 completely recovers. Therefore, the upper surface of the wedge-shaped limiting post 223 on the rotary lock 22 contacts the bottom surface 5123 of the main-plate wedge-shaped limiting member 512 and generates an interaction force, so that the wedge-shaped limiting post 223 is tightly engaged with the main-shaped wedge-shaped limiting hole 51. In addition, there are two central snaps 18 in the middle of the connector body 1 to make the cooperation between the connector and the main body 5 stronger.

[34] After the connector 拆卸 is removed, the handle 216 of the dial 21 is turned, causing the torsion spring 23 to deform, and the wedge-shaped limit post 223 on the connector lock 22 returns to the position of the corner surface 5122, and the stylus 32 is elastic. Under the action, the wedge surface of the wedge-shaped limiting post 22 3 is disengaged along the wedge-shaped surface 5121 of the main wedge-shaped limiting member 512, thereby achieving the purpose of separating the connector from the main body 5.

[35] In summary, the connector provided by the present invention takes advantage of the stylus connector, changes the nut locking structure, and is self-locking in the form of a dial, which is extremely simple to install and disassemble. In addition, through the reasonable configuration of the internal space, the scheme is compact, and the volume is greatly reduced compared with the conventional connector structure; the connecting component is integrally formed in the connector body, thereby greatly improving the waterproof performance.

[36] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and any person skilled in the art can easily think of within the technical scope disclosed by the present invention. Changes or substitutions are intended to be included within the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
