Embodiments of the invention

Referring to FIGS. 1-3, the rotatable connector 100 provided by the present invention includes a base 110 for connecting cables, an adapter 130 connected to the base 100, and a plug 150 connected to the connection portion 130. . The adapter 130 is coupled between the base 110 and the plug 150. The first end 131 of the adapter 130 is rotatably coupled to the front end of the base 110, and the second end of the adapter 130 is rotatably coupled to the plug 150. The overall process of ultrasonic assembly is used to achieve a 360 degree rotation between the three main parts of the product.

Referring to FIGS. 4 and 5, the front end of the base 110 is provided with a cavity 111, and the opposite inner side walls of the adapter cavity 111 are respectively provided with circular first connecting holes 113. The adapter 130 is embedded in the cavity 111. Specifically, the first end 131 of the adapter 130 is respectively provided with a cylindrical outwardly projecting first connecting portion 135 on the opposite outer sidewalls. The two first connecting portions 135 are respectively inserted into the two first connecting holes 113 of the cavity 111, and are rotatable under the constraint of the two first connecting holes 113.

[0025] A first line passage is disposed in the base 110, and the first line passage is in communication with the first connection hole 113. That is, after the external cable enters the susceptor 110, it can exit through the first connection hole 113.

A second through passage is disposed in the adapter 130. The first connecting portion 135 is hollow to communicate with the second through passage for the cable to pass through. After the external cable enters the base 110, it can exit through the first connection hole 113 and enter the adapter 130 via the first connection portion 135.

[0027] As described above, the two first connecting portions 135 are respectively engaged with the two first connecting holes 113, thereby achieving relative rotation between the base 110 and the adapter 130.

[0028] In order to achieve relative positioning between the pedestal 110 and the adapter 130, the embodiment has a bump-and-groove structure. Specifically, the hollow cylindrical first connecting portion 135 is provided with a plurality of recesses 136. At least one positioning protrusion 115 is disposed in the first connection hole 113. The adapter 130 is assembled to the base 110, the first connecting portion 135 extends into the first connecting hole 113, and the positioning protrusion 115 in the first connecting hole 113 cooperates with the recess 136 of the end surface of the first connecting portion 135. . That is, when the adapter 130 is rotated relative to the base 110 until the positioning projection 115 falls into the recess 136, the adapter 130 and the base 110 will remain in the current rotational position; The force is large enough that the locating projection 115 will enter the other recess 136 from the current recess 136.

[0029] As described above, the adapter 130 and the base 110 are relatively rotatable and held in the desired rotational position by the embossed latch structure.

[0030] In order to make the rotation smoother, the adapter first connecting portion 135 is slightly tightly fitted with the corresponding first connecting hole 113.

Referring to FIG. 5 and FIG. 6, the second end 133 of the adapter 130 is rotatably coupled to the plug 150. The end of the second end 133 of the adapter 130 is provided with a wire hole 137, and the wire hole 137 is located at the center of the second end surface of the adapter and communicates with the second wire passage. The wire hole 137 communicates with the inner holes of the two first connecting portions 135 to form a T-shaped wire passage, and the T-shaped wire passage also communicates with the first connecting hole 113 to facilitate the passage of the transmission wire. The transmission wire penetrates along the rear end of the base 110, passes through the first connection hole 113, the first connection portion 135, and the wire hole 137, and is connected to the terminal of the plug 150.

[0032] The adapter 130 is generally T-shaped, and the first end 131 of the adapter 130 is small in size to mount the cavity 111 of the base 110, and the second end 133 of the adapter 130 is relatively large in size. Preferably, the first end 131 of the adapter 130 has an arcuate surface to avoid interference with the inner wall of the cavity 111 during rotation.

Referring to FIGS. 6 and 7, the tail end of the plug 150 is provided with a cylindrical second connecting portion 155 that is convex toward the adapter 130. The second connecting portion 155 extends into the through hole 137 of the adapter 130. Specifically, the end surface of the second end 133 of the adapter 130 is the bottom plate 136, and the bottom plate 136 is bored to form the wire hole 137.

[0034] The end surface of the second connecting portion 155 is provided with an outer edge 151. Therefore, the second connecting portion 155 forms a neck between the outer edge 151 and the main body of the plug 150, and the neck portion can be caught in the through hole 137 of the bottom plate 136. Thereby, the relative rotation of the plug 150 and the adapter 130 is ensured, and the detachment of the plug 150 from the adapter 130 is prevented.

[0035] The end surface of the second connecting portion 155 has a convex first limiting block 153. A second limiting block 153 is disposed in the adapter 130. The first limit block 153 cooperates with the second limit block 153 to prevent the plug 150 from rotating more than 360 degrees relative to the adapter 130.

[0036] Referring to FIG. 8, as an alternative, the outer edge 151 is further provided with a plurality of concave positions 152. Correspondingly, the adapter member 130 is provided with a plurality of matching protrusions for stable positioning during rotation. . The positioning principle is similar to the positioning principle of the above-mentioned concave and convex card structure, and will not be described in detail.

[0037] It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and scope of the invention. Therefore, the protection model of the patent of the present invention The following claims are subject to the appended claims.
