Description

Technical Field

[0001] The utility model relates to a connector, in particular to a seat shell and a socket. Background Art

[0002] Existing circular plug-in connectors are divided into straight-insert bolt locking and push-pull locking types. Both types of connectors have no interlocking function after the plug and socket are plugged in, and have poor vibration and impact resistance. At the same time, when the plugs and sockets of the two connectors are separated, only an axial force is required to directly separate them, which has poor reliability. In addition, the existing three-slot screw locking connector requires three spiral grooves for three-slot screw locking, which is difficult to process and requires high precision. At the same time, when the connector is plugged in and out, the connecting sleeve needs to be rotated at least 120 degrees, requiring a large operating space and a large torque, making separation more difficult.

[0003] After long-term research, the inventors proposed a circular straight-plug connector, and improved the plug thereof. Utility Model Content

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, a circular straight plug connector includes a plug 100 and a socket 200. Figure 6 and Figure 7 As shown, the plug 100 includes a head shell 101 and a connecting sleeve 104. A head mounting plate 102 is installed in the head shell 101, and a head contact 103 is installed in the head mounting plate 102. In this embodiment, the head mounting plate 102 and the head contact 103 are both existing structures, and their installation method is also existing technology, so their structure and installation method will not be described in detail.

[0033] In this embodiment, if Figure 8 As shown, a circumferential waist-shaped hole 113 is provided at the right end of the head shell 101, and a circumferential waist-shaped groove 114 is provided in the middle of the head shell 101. The circumferential waist-shaped hole 113 and the circumferential waist-shaped groove 114 both extend in the circumferential direction. A sliding groove 117 is provided at the left end of the head shell 101, and the sliding groove 117 is connected to the corresponding circumferential waist-shaped groove 114. The connecting sleeve 104 is sleeved on the head shell 101, and the connecting sleeve 104 can rotate relative to the head shell 101, as shown in FIG. Figure 9As shown, a first rivet hole 121 and a second rivet hole 122 are provided on the connecting sleeve 104, a first rivet 111 is installed in the circumferential waist-shaped hole 113, the bottom of the first rivet 111 is located in the inner cavity of the head shell 101, the top of the first rivet 111 is riveted in the first rivet hole 121, a second rivet 112 and a return spring 116 are installed in the circumferential waist-shaped groove 114, the top of the second rivet 112 is located in the second rivet hole 122, one end of the return spring 116 abuts against the second rivet 112, and the other end of the return spring 116 abuts against the side wall of the circumferential waist-shaped groove 114 away from the sliding groove 117. Further, as shown Figure 8 As shown, plugs 115 are installed at both ends of the return spring 116, one of which is in contact with the second rivet 112, and the other plug 115 is in contact with the side wall of the circumferential waist-shaped groove 114 away from the sliding groove 117. During installation, the return spring 116 is first installed between the two plugs 115, and then the return spring 116 and the plug 115 are placed in the circumferential waist-shaped groove 114. Then, the top of the second rivet 112 is inserted into the second rivet hole 122, and the second rivet 112 is aligned with the sliding groove 117, and the second rivet 112 is snapped into the sliding groove 117. Then, the connecting sleeve 104 is pushed to move axially, thereby causing the second rivet 112 to move along the sliding groove 117 and finally enter the circumferential waist-shaped groove 114, and then the position of the connecting sleeve 104 is adjusted circumferentially so that the first anchor hole and the second rivet 112 are aligned. The circumferential waist-shaped holes 113 are aligned, and then the top of the second rivet 112 is inserted into the second anchor hole from the bottom of the circumferential waist-shaped hole 113. At this time, the return spring 116 is in a compressed state, and one plug 115 abuts against the second rivet 112, and the other plug 115 abuts against the side wall of the circumferential waist-shaped groove 114 away from the sliding groove 117. Then, the top of the first rivet 111 and the second rivet 112 are riveted using a riveting process, so that the first rivet 111 will not fall out of the first rivet hole 121 and the second rivet 112 will not fall out of the second anchor hole. Preferably, the first rivet 111 and the first rivet hole 121 are clearance-fitted. After the first rivet 111 is riveted, the first rivet 111 can also rotate axially relative to the first rivet hole 121, thereby facilitating the first rivet 111 to move on the first arc 213.

[0034] In this embodiment, if Figure 4 As shown, the first rivet 111 is a stepped column, and the diameter of the large end of the first rivet 111 is larger than the axial width of the circumferential waist-shaped hole 113. Therefore, when the first rivet 111 is riveted and installed, the first rivet 111 cannot fall out of the first rivet hole 121 no matter where the plug 100 is located, due to the riveted joint at the top and the large end at the bottom, thereby ensuring the reliability of the installation of the first rivet 111.

[0035] In this embodiment, the second rivet 112 is a stepped column, and the large end diameter of the second rivet 112 matches the axial width of the circumferential waist-shaped groove 114, so that the second rivet 112 can only move in the circumferential direction when in use, so that the elastic restoring force of the reset spring 116 can act well on the second rivet 112, thereby ensuring that the connecting sleeve 104 rotates in the circumferential direction relative to the head shell 101 under the action of the elastic restoring force.

[0036] In this embodiment, if Figure 8 As shown, the depth of the circumferential waist-shaped groove 114 is greater than the depth of the sliding groove 117. Preferably, the circumferential waist-shaped groove 114 and the sliding groove 117 form an L-shaped groove. Therefore, when the second rivet 112 slides into the circumferential waist-shaped groove 114, the circumferential spacing between the second rivet 112 and the plug 115 is at a maximum value. As the connecting sleeve 104 rotates, the second rivet 112 gradually approaches the plug 115 and finally abuts against the plug 115, thereby causing the return spring 116 to produce elastic deformation. Furthermore, the height of the large end of the second rivet 112 is less than or equal to the depth of the sliding groove 117. When the second rivet 112 slides into the circumferential waist-shaped groove 114, the second rivet 112 falls into the circumferential waist-shaped groove 114 under the action of its own weight. At this time, the operator can observe the position of the top of the second rivet 112 to determine whether the second rivet 112 has entered the circumferential waist-shaped groove 114.

[0037] In this embodiment, the socket 200 includes a seat shell 201, a seat mounting plate 202 and a seat contact 203. The seat mounting plate 202 is installed in the seat shell 201, and the seat contact 203 is installed in the seat mounting plate 202. The seat mounting plate 202 and the seat contact 203 are both existing structures, and their installation method is also existing technology. Therefore, their structure and installation method will not be described in detail.

[0038] In this embodiment, if Figure 9 、 Figure 10 and Figure 11As shown, the left end of the seat shell 201 is the plug-in end, and a vertical groove 211 and a guide groove 216 are provided on the plug-in end. In the circumferential direction, the guide groove 216 is located on one side of the vertical groove 211, and a transverse groove 212 is provided at the bottom of the vertical groove 211. The transverse groove 212 extends toward the guide groove 216. The groove wall of the vertical groove 211 near the transverse groove 212 is an arc structure and forms a first arc 213. The left side wall of the transverse groove 212 is an arc structure and forms a third arc 215. The connection between the first arc 213 and the third arc 215 is through The second arc 214 transitions smoothly, thereby making the second arc 214 have a height. Furthermore, a guide protrusion 118 is further provided in the inner cavity of the right end of the head shell 101. During the plug-in process of the plug 100 and the socket 200, the guide protrusion 118 is first aligned with the guide groove 216, and then the plug 100 and the socket 200 are directly inserted. Due to the cooperation of the guide protrusion 118 and the guide groove 216, the head shell 101 and the seat shell 201 are both axially moved relative to each other, thereby making the head contact 103 and the seat The contact piece 203 is plugged in, and the guide protrusion 118 is inserted into the guide groove 216. During the plugging process, the first rivet 111 enters the vertical groove 211 and rolls along the first arc 213. After the first rivet 111 rolls along the first arc 213, the first rivet 111 rotates in the circumferential direction relative to the head shell 101, thereby driving the connecting sleeve 104 to rotate in the circumferential direction. After the connecting sleeve 104 rotates in the circumferential direction, the second rivet 112 is squeezed and reset. The spring 116 increases the deformation of the return spring 116. As the plug 100 and the socket 200 are plugged in, the first rivet 111 transitions from the first arc 213 to the second arc 214. After the first arc passes over the second arc 214, the spring restoring force of the return spring 116 causes the connecting sleeve 104 to rotate in the opposite direction, thereby causing the first rivet 111 to enter the transverse groove 212. Applying a pulling force to the plug 100 or the socket 200 causes the first rivet 111 to enter the third arc 215.

[0039] In this embodiment, in the axial projection, the transverse groove 212 is located on one side of the vertical groove 211, and the return spring 116 is located on the other side of the vertical groove 211, and the arc length of the circumferential waist-shaped hole 113 matches the arc length of the first circular arc 213, and the angle between the left end and the right end of the first circular arc 213 is less than 30°. Furthermore, the initial position of the first rivet 111 in the circumferential waist-shaped hole 113 is the nearest end, so after the first rivet 111 moves from the leftmost end to the rightmost end of the first circular arc 213, the first rivet 111 moves from the nearest end to the farthest end of the circumferential waist-shaped hole 113, and when the first rivet 111 enters the second circular arc 214, the first rivet 111 begins to move from the farthest end to the nearest end, and when the first rivet 111 passes the high point of the second circular arc 214, the first rivet 111 moves quickly to the nearest end.

[0040] In this embodiment, if Figure 9 、 Figure 10 and Figure 11 As shown, the seat shell 201 has multiple sections of cylinders, which are the first cylinder 221, the second cylinder 222, the third cylinder 223 and the fourth cylinder 224 from left to right. The vertical groove 211 and the guide groove 216 are opened on the second cylinder 222. The outer diameter of the first cylinder 221 is smaller than the outer diameter of the second cylinder 222, and the outer diameter of the second cylinder 222 is smaller than the outer diameter of the third cylinder 223. An annular groove is opened at the connection between the first cylinder 221 and the second cylinder 222, and a sealing ring 204 is installed in the annular groove. The outer diameter of the sealing ring 204 is smaller than the outer diameter of the second cylinder 222, and the outer diameter of the sealing ring 204 is larger than the outer diameter of the first cylinder 221. Further, as shown Figure 5 As shown, a resisting step 119 and a limiting step 123 are provided in the inner cavity of the head shell 101. The inner diameter of the limiting step 123 is smaller than the inner diameter of the resisting step 119. The inner diameter of the resisting step 119 matches the outer diameter of the first cylinder 221. When the first rivet 111 moves to the highest point, the squeezing of the sealing ring 204 by the resisting step 119 reaches the maximum limit. Since the sealing ring 204 is an O-ring 204 made of rubber material, the O-ring 204 can be elastically deformed. After the resisting step 119 squeezes the sealing ring 204, the sealing ring 204 has an elastic restoring force on the resisting step 119. After the first rivet 111 passes the high point, the elastic restoring force of the sealing ring 204 enables the first rivet 111 to enter the third arc 215. At this time, the sealing ring 204 is also in a compressed state, thereby realizing sealing when the plug 100 and the socket 200 are plugged in.

[0041] In this embodiment, when the plug 100 and the socket 200 are separated, the connecting sleeve 104 is rotated circumferentially, so that the first rivet 111 enters the second arc 214 from the second arc 214 and moves to the highest point of the second arc 214. At this time, the return spring 116 is at its maximum compression, and then an axial tension is applied to the connecting sleeve 104, and the first rivet 111 enters the vertical groove 211 from the highest point. At this time, the connecting sleeve 104 can be released, and the connecting sleeve 104 rotates in the opposite direction under the action of the return spring 116, and the first rivet 111 moves along the trajectory of the first arc 213, thereby separating the plug 100 and the socket 200.

[0042] In this embodiment, if Figure 9 、 Figure 10 and Figure 11As shown, a mounting flange 205 is provided on the third cylinder 223, and a mounting hole is provided on the flange to facilitate the installation of the socket 200. Furthermore, an external thread is provided on the fourth cylinder 224, and a back-off groove is provided between the fourth cylinder 224 and the third cylinder 223, so that the external thread on the fourth cylinder 224 can be conveniently connected to the tail accessory thread.

[0043] In this embodiment, there are two vertical grooves 211, guide grooves 216, circumferential waist-shaped grooves 114, and circumferential waist-shaped holes 113, and they are evenly distributed on the same circumference, so that the plug 100 and socket 200 insertion and separation force are softer, greatly improving the installation and use efficiency of the connector.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
